The hole in the regulator for the passage of heavy deposits on discharge is made equal to the corresponding input and output holes of the fittings of the regulator. 4 Il., table 1. The invention relates to the processing and washing technique and can be used in various industries.Known washing machine containing ink outlines preliminary and OK the wires for the supply of the working agent to inkjet outlines preliminary and final processing intake pipe which is connected to the outlet pipe of the pump, and the discharge pipe of the pipeline for the supply of the working agent is connected with jet contour final processing through the hydrocyclone cleaning of light sediments (USSR author's certificate N967595, CL B08B 3/02, 1981).The disadvantage of analog is inefficient mechanical hydraulic impact of the jet on the treated contaminated surface products due to the lack of a solid filler in the washing solution.The technical essence and the principles of implementation the closest to the claimed technical solution is a washing machine containing ink outlines preliminary and final processing hydrocyclone cleaning of light sediments, capacity for working agent with the pump, the piping for supplying the working agent to inkjet outlines preliminary and final processing, intake pipe which is connected with the outlet pipe of the pump, and the discharge pipe of the pipeline for the supply of the working agent is connected with jet contour final processing through the hydrocyclone cleaning of light sediments, while it has hydrocyclone separation of heavy sediments, built-in pipes, light sediment in the direction of the working agent, moreover, the nozzles of the waste outlet of the hydrocyclone separation of heavy deposits connected with a pipeline for the supply of the working agent to inkjet contour pre-treatment (USSR author's certificate N971528, CL B08B 3/02, 1982).The disadvantage of the prototype is the inability to control the concentration of particulate filler in manufacturing hydraulic jet, as with the same parameters supplied by a pump operating agent (the pressure of the liquid, the size and concentration of pollutants) and nereguliruemost (stiffness) of the structural parameters of the hydrocyclone from the nozzle to the waste outlet of the hydrocyclone separation of heavy deposits in the piping for supplying the working agent to inkjet pre-processing circuit receives heavy deposits of certain malaysiensis (unregulated) concentration.It is known (see, for example, Khudobin L. C. Berdichevsky that is, the Technique of application of lubricant-coolants in metal cutting. M. engineering, 1977, S. 189, S. 79), from the output nozzle of the hydrocyclone heavy sediments (particles) come from some part of the liquid 5 to 15% of the total volume of fluid, the directional pump in the hydrocyclone. If you ask the original heavy concentration of 5% and as a practical expedient, to assume the approximate equality of expenditure flows of the working solution in both circuits, the cost of working agent supplied by a pump in the circuit pre-treatment (KPOand in hydrocyclone separation of heavy sediments (Hz) should also be approximately equal (or be comparable). Thus, ifKPO=Hz=1, then the concentration of the solid filler in the working solution of the pre-processing circuit will be:
.The inability to control the concentration of particulate filler, and flow rate of the washing solution in the final processing circuit does not select the processing modes and cleaning products with different types and degrees of contamination of their surface, reduces the quality of the processing and washing, narrows the scope of the prototype.The purpose of the invention, the expansion of technological capabilities, improve the quality of treatment and washing.This goal is achieved by the fact that the installation for processing and washing, containing inkjet pre-processing circuit with hydrocyclone separation of heavy sediments and inkjet final processing circuit with hydrocyclone Department of the major contours of the preliminary and final processing intake pipe which is connected with the outlet pipe of the pump, while the hydrocyclone separation of heavy deposits embedded in the pipeline for the supply of the working agent to inkjet contour final processing before hydrocyclone separation of light sediments is further provided with Bolotnikova regulator costs of heavy sediments and cleaned working agent connected with two output fittings with tubing for the supply of the working agent to inkjet contour pre-treatment and one with a drain line to an excess of heavy deposits in the tank and through the two inlet fittings with the waste outlet of the hydrocyclone separation of heavy sediments and one with tubing connected to the output of the purified agent hydrocyclone separation of light sediments, the orifices in the valve for the passage of heavy sediments and cleaned working agent to inkjet pre-processing circuit is made large, the respective inlet and outlet openings of the fittings regulator, and their great distance from the center distances between the input and output holes of the fittings regulator, and the hole in the regulator for the passage of heavy deposits on the drain is made of the type and similar, the claimed technical solution is further provided with a pipeline connecting the outlet cleared a working agent hydrocyclone cleaning of light sediments (i.e., the pipeline for the supply of this solution to jet contour final processing) with a pipeline for the supply of the working agent to inkjet contour pre-treatment, and control costs: heavy sediment and cleaned working agent coming in the pipeline for the supply of the working agent to inkjet contour pre-treatment, respectively, from the outlet of the hydrocyclone separation of heavy sediments and from a pipeline connected to the output of cleaned working agent hydrocyclone cleaning of light sediments, as well as an excess of hard deposits (formed during operation of the low concentrations of heavy deposits in the desktop agent is supplied to the circuit pre-processing), stitched through the valve of the regulator to the tank.The orifices in the valve regulator for the passage of heavy sediments and cleaned working agent to the pre-processing circuit is made large, the respective inlet and outlet openings of the fittings regulator, and their distance Otley is tnike to drain heavy sediment in the tank is made equal to the corresponding input and output holes of the fittings of the controller.Thus, the following two additional features - continuously variable (in the whole range of, for example, from 3.7 to 8.7%) of the regulation of the concentrations of heavy deposits in the desktop agent is supplied to the jet path pre-processing, and automatic throttling (flow), peeled working agent in the jet path final processing (i.e., the intensity of the final wash) depending on the concentrations of heavy deposits in the desktop agent is supplied to the jet path pre-treatment. As these functions, and methods for their implementation are not known neither the prototype nor the similar.All this together leads to the conclusion on the compliance of the claimed technical solution the criteria of "novelty" and "significant differences".In Fig. 1 shows a schematic diagram of the installation of Fig. 2 - possible position of the valve; Fig. 3 corresponding concentration values (K) of the solid filler in the desktop agent circuit 6 of Fig. 4 - curves of dependences of spending a working agent in the circuits 6 and 7 and the total (depending on To.Installation for processing and washing has a reservoir 1 with a working agent, nasosy collection, inkjet contours of the pre-treatment 6 and final processing 7. Capacity 1 mesh filter is divided into two compartments desktop 9 and spent 10 agent. Pump 2 suction pipe 11 is connected with the compartment 9, and the discharge pipes 12 and 13 respectively with the cyclone 3 and jet circuit 6. The hydrocyclone 3 pipe 14 release agent containing light deposits, connected to the inlet pipe 15 of the cyclone 4. The hydrocyclone 4 output 16 cleaned agent connected to the blasting circuit 7, and the output 17 of the waste to the tank 5. Circuit 6 carries out pre-processing (washing, cleaning), contour 7 - final processing (washing).The output 18 of waste containing heavy deposits of hydrocyclone 3, and the output 16 of the purified agent hydrocyclone 4 (line 19) is connected to the inlet fittings 20 and 21 of the controller 22 of the costs of heavy sediments and cleaned working agent.Output fittings 23 and 24 of the controller 22 are connected respectively by pipes 25 and 26 with the pipe 13 for supplying a working agent to the circuit 6. (The connection may be made in the form of ejection devices 27).In addition, the output 18 of the cyclone 3 is connected through a tee 35 to the inlet 36 reg the events in the compartment 9 of the tank 1.Thus, the controller 22 has three input (20, 36 and 21) and three output (23, 37 and 24) of the nozzle. The spool 28 of the slider (sliding, rotary or other type) has openings 29, 30 and 39 for the passage respectively of heavy sediments and cleaned working agent. These holes are made large, the corresponding input 31, 32 and 40 and the output 33, 34 and 41 of the holes in the fittings 20, 21, 36, 23, 24 and 37 by a certain amount. Holes 29, 30 and 39 may be made of circular or non-circular shape (ellipse, rectangular, etc). Thus, the size D of the holes 29 more size DDD holes 31, and the size D of the hole 33 on the value of D. I.e.L29-D31=D29-D33= D1.
Similarly, D30-D32=D30-D34= D2.
The distance between the axes of the holes 29 and 30 are made different from the distance AND1between the axes of the holes 31 and 32 and holes 33 and 34. Possible options: <1(shown on Fig. 2) or A > AND2.The hole 39 is made equal to its corresponding inlet 40 and outlet 41 of the holes in the fittings 36 and 37. In turn, the holes 40 and 41 is made equal to the holes 31 and 33. I.e., D39D40D41D31D33. If this is Tajani at exit 18 (a) and the total in the hole 31 (1and the holes 40 (2), i.e.1+2= - at different positions of the spool 28.Tee 35 is made with the possibility to freely drain through him excessive amounts of solid sediments from holes 31 (in case of partial or complete overlap of the spool 28) into the hole 40. The spool 28 of the regulator can be executed with the manual or mechanized (automated) drive motion.Installation for processing and cleaning works as follows.The working agent, pre-cleaned through the filter 8, the pump 2 is drawn out of the compartment 9 of the tank 1 and through the pipeline 12 is fed to the hydrocyclone 3, and the pipe 13 in the circuit 6. In the cyclone 3 is the separation of the working agent from which emit the heavy sediments (sand, clay, small chips, scale, etc.,) and from the output 18 together with some part of the fluid received in the socket 20 and 36 of the regulator. The main part of the liquid (up to 85 to 95%) through the nozzle 14 is directed into the inlet 15 of the hydrocyclone 4, in which it is cleared from the lung deposition and through the exit 16 enters the circuit 7, and the pipe 19 into the socket 21 of the regulator. Separated from the liquid in the cyclone 4 pollution through the exit 17 atlautla in certain quantities, depending on the position of the valve 28, respectively, through the fittings 23 and 24, the pipes 25 and 26 in the pipe 13 and the circuit 6. Due to the displacement flow of the working agent, moving through the pipes 13, 25 and 36, in the circuit 6 is formed by a flow of processing agent with a solid filler concentration of the latter, an adjustable within wide limits, providing pre-blasting products. In the circuit 7 is the final processing of the product purified from all kinds of contamination of the liquid working agent. Arising on the product surface from the nozzles of inkjet circuits 6 and 7 working agent together with pollution flows into the container 1, and the cycle repeats.The design of the controller provides infinitely variable regulation of the concentration of particulate filler in the working agent in the circuit 6. In Fig. 2 shows the seven provisions of the spool 28 of the regulator, including extreme I and VII, and Fig. 3 corresponding received the concentration of particulate filler (To,). In the first position when the openings 31 and 33 are fully open and the holes 32 and 34 are fully closed, the value of To (coincides with that achieved For the prototype) maximum, for example 8,7% (Fig.3). In the seventh position when, on the contrary, overstaging deposits in the compartment 9 of the tank 1). Gradually changing the position of the spool 28, the transition from I to VII position, i.e. pushing it from the chassis controller on the value of L1L6get gradually decrease and, conversely, when pushing it into the body, increasing K. the Dependence f(L) (valve position) can be linear or nonlinear depending on the shape of the holes 29 and 30, on the ratio of their sizes (square bore) with the size of the holes in the fittings 20, 21 and 23, 24, as well as on the ratio between the quantities a and a2.In cases of partial or complete overlap of the spool 28 of the bore hole 20 automatically opens the valve 28 by the same amount the flow area of the holes 40. (Regulation V, VI and VII of the valve). Thus, in these cases, part of the flow (or the whole thread) working agent containing heavy deposits, is discharged through the tee 35, the orifice 40 of the nozzle 36, the hole 39, the hole 41 of the fitting 37 and pipe 38 in section 9 of the tank 1, i.e., if you need to get in the circuit 6 a reduced concentration of particulate filler in the desktop agent (less than 15 12% according to the schedule in Fig. 3) the flow of the working agent with a heavy sediment from the output 18 of the cyclone 3 is partially or fully discharged into the tank 1.In position I of the valve 28, when the holes 32 and 34 are fully closed, the flow GTfully enters the loop 7 (o= 0,7225). The provisions of II-IY these holes, opening up about 1/3, 2/3 and full, direct part of the flowGPin the pipeline 13, slimming oaccordingly to 0.62, 0.51 and 0,4 (o=0,4) conditionally adopted by the min value flowing in the circuit 7, still providing high-quality final washing and component, for example, a large part of the value ofGT= 0,7225.Similarly, the provisions V VII of the spool 28, the flow rate of 0.18 directed into the pipe 13 also changes to reflect postaer> The obtained data on the change in the concentration of particulate filler in the desktop agent (loop 6) and the flow of the working solution depending on the position of the slide valve 28 is shown in the table (initial concentration To heavy deposits in the desktop agent is supplied by a pump, adopted 5%).According to the data obtained the dependencesp,oand from K (or h) (Fig. 4), showing the relative invariabilitygradual automatic increase of the flow rate qocleaned working agent in the circuit 7 with increasing concentrations of heavy deposits in the desktop agent is applied to the circuit 6. The increase leads to an increase in settling on the surface of workpiece machining of heavy particles and products to the needs of the increasing consumptionoin the circuit 7 to ensure the quality of washing. On the contrary, when used in circuit 6 working agent with smaller values To the possibility of reducing flowocircuit 7 (underused in the circuit 7 partoautomatically used for reduction in circuit 6).Positive technical and economic effect from the use of the proposed t is abode, cleaning and washing products due to the stepless regulation of the concentrations of heavy deposits in the desktop agent is applied to the pre-processing circuit, and automatically controlling the flow of purified working agent in the loop final cleaning. Installation for processing and washing, containing inkjet pre-processing circuit with hydrocyclone separation of heavy sediments and inkjet final processing circuit with hydrocyclone cleaning of light sediments, capacity for working agent with the pump, the piping for supplying the working agent to inkjet outlines preliminary and final processing, intake pipe which is connected with the outlet pipe of the pump and hydrocyclone separation of heavy deposits embedded in the pipeline for the supply of the working agent to inkjet contour final processing before hydrocyclone separation of light sediments, characterized in that it further provided with Bolotnikova regulator costs of heavy sediments and cleaned working agent connected with two output fittings with tubing for the supply of the working agent to inkjet contour pre-treatment and one with Truboprovod Department of heavy sediments and one with the pipeline, connected to the output of the purified agent hydrocyclone cleaning of light sediments, the orifices in the valve for the passage of heavy sediments and cleaned working agent to inkjet circuit pre-processing large respective inlet and outlet openings of the fittings regulator, and their distance is different from the axial distance between the input and output holes of the fittings regulator, and the hole in the regulator for the passage of heavy deposits on the drain is equal to the corresponding input and output holes of the fittings of the regulator.
