They consist of a Central beam 29 with transverse grooves 30 on the ends for insertion of the tie rods 31 (see Fig.5). The beam 29 is centered between the brackets 28 fixed to the transverse axis 32, the ends of which are pivoted two equal armed beam 33. On the shoulders of the rocker arm pivoted supporting elements consisting of two plates 34, fastened to each other by rigid ribs 35. The inner side of the side walls 27 cassette form made the slots 36, which are inserted transverse partition 37, limiting molded blocks.

For molding concrete wall blocks of high operational availability of the surface forms the inner surface of senokosnaya, side walls, partitions and slots must comply with the tolerances classes H14-H12 on metal.

Stacker (Fig. 6,7) consists of a stationary U-shaped frame 38, in vertical racks which move the carriage 39 by means of hydraulic cylinder 40. The carriage by means of the hinge 41 is connected with the deviating frame 42, which is equipped with lugs 43 with the lower support plates 44, copiers 45 with broken profiles and two roller 46. On the U-shaped frame are two two shoulders of the lever 47 with rollers 48. Two shoulders levers in the idle state is pressed by a spring 49 to the lugs 50. In the lower part on upright stationary frame 38 posted linear copiers 51. The stacker is mounted above the roller conveyor 52, which are moved by the method of pushing each other to form 1 for production of wall blocks. The Foundation of the forms provided with end lugs 53.

Device for dispensing liquid according to Fig.8 consists of a feed tank 54, which is connected by a pipe 55 through the electromagnetic valve 56 with pump 57 through the side hole. Through the second side opening of the spout 57 is connected by a pipe 58 through the electromagnetic valve 59 with the pointer 60 of the liquid level in the supply tank 54. On the pipe 58 between electromuse air. The dispenser is equipped with an outlet pipe 62 with solenoid valve 63 and the supply tank -54 discharge valve 64.

The dispenser depicted in Fig.9, includes a hollow body 65 with two side nozzles 66,67 and a bottom outlet pipe 68. In the cavity of the housing 65 is placed a hollow cylinder 69, fixed by means of the outer sleeve 70 and the inner sleeve 71, which is placed between the stuffing box gasket 72. The upper base of the cylinder 69 is provided with a Central nut 73 which is screwed an adjusting screw 74, passed through the support bracket 75. The support bracket 75 of the lower flanges connected with the flange of the outer sleeve 70. One of the rack support bracket 75 is equipped with a scale 76 configuration of the dispenser, which moves the stopper 77.

Line for the production of expanded clay concrete blocks is as follows. After Assembly cassette form 1 on the conveyor 14 return, they go on the roller conveyor 2 of the first vibrator 3, combined with the hopper 4 of the clay fraction 20-40 mm On the vibrator are filling clay forms and seals. After that, the cassette 1 is moved to the turntable 5, unfold the 90oand served on the conveyor 6 of the second vibrating table 7, combined with a drive-Cam-the x pre-prepared concrete mixture from the accumulator-distributor 8. The mix is prepared in the mixer 16 that connects dispensers 17 connected to the hoppers 18, 19 of cement and sand, as well as dispensers 20 water and surfactant solution through which served on the initial part of the roller heat chamber 9, where with the help of the pusher 10 and the side of the lift 11 or hoist clarify its position and the pushing method to move the stacker 12, which raises cassette form and after you move another form under a raised down first then moved. If necessary, we can capture stacks of two forms, his rise and set on then moved another form (option three-tiered stacks). The latter form pushes the stack from under the truck racks 9, stacker her up and set on after roaming. When bunk stack another further form pushes for two stacks of form of pushes for two stacks of forms, pushing out the last stack from the stacker in the heat chamber 9. Thus, in the heat chamber 9 is formed by a chain of two - or three-tiered stacks of cassette form.

After passing the first section of the heat chamber 9 with the help of crane 13 and the plunger 22 a stack of cassette forms move the second section of the term is Fig.2). The output of the last section of the heat chamber of the hoist 13 remove the upper and then the lower cassette forms and submit them to the conveyor 14 return cassette form. On this site carry out the dismantling of the cassette, through the mechanism 15 pickup units transferred to finished blocks on a pallet, shall be cleaned, subsequent lubrication and Assembly of forms, and then move them on to the roller conveyor 2 of the first vibrator for backfill clay.

The proposed line for the manufacture of expanded clay concrete blocks, equipped with sectional racks that allows you to organize the work of the sections and in the same direction. To do this, the stacks of cassettes are served not only in the first section, but in the second, third, fourth, etc., In this case, the speed of advancement of cartridges less, and the total number of cassettes remains the same. The heat treatment time is calculated based on parameters mixes. The output sections of the heat chambers eat and the transfer of tapes on the conveyor return carried out sequentially as their output sections of the heat chamber.

This option is the organization of the line allows in case of failure or breakage of one section of the heat chamber to continue the work of others, and at this time to carry out the adjustment of the emergency section. Povysheniya form (Fig.3,4 and 5) works as follows. Attached hinged to the base 26 of the folding side walls 27 is installed in a vertical position and fix nested in the transverse grooves 30 on the ends of the Central beam 29 of the side clamps coupling pins. In the slots 36 with the inner sides of the side walls 27 is inserted transverse partition 37 forming section forms. Affect the use of the tie rods 31 of the side clamps to fully embrace the ends of the walls 37 of the slot 36 on the side walls. When the contraction of the lateral clamps efforts transmitted to the Central beam 29 that is attached to the bracket 28 through the transverse axis 32 is transmitted to hinged equal armed beam 33 and then evenly distributed on the hinged support elements consisting of two bonded hard edges 35 of the plate 34, which is strictly accurately fixed to the side walls of the cassette form.

Proposed cassette form allows you to mould lightweight keramzitobetonnye wall blocks high factory readiness, clutches that are available on adhesives and mastics with a thickness of not more than three millimeters. The dimensional accuracy and surface quality building blocks allow you to plug the easier concrete wall blocks high factory readiness successfully implemented in the Moscow firm "Annex".

Stacker (Fig.6 and 7) works as follows. In the production line of the roller conveyor (roller) 52 before the stacker is placed in one floor of form 1. The movement of the forms is carried out by pushing them into each other by stops 53 in step mode. The stacker is positioned so that its vertical axis deviating frame 42 coincides with the axis passing through the center of gravity of the shape, which is designed for lifting. The rise of form 1 as follows. In rod cylinder chamber 40 serves oil and stem, pulling, moving up in the guiding pillars of the frame 38 of the carriage 39, while providing a plane-parallel (without tilting) movement of the two hinge arms 41, which are deviating frame 42. Located on deviant frame 42 stops 43 take the form 1 bottom center of gravity and move it up. In the first stage of lifting two rollers 46 deviant frame roll on copiers 51, located on the stationary frame 38 that provides a strictly vertical movement of the form 1. At the end of this section, the rollers 48 come in contact with copiers 45, which determine the future trajectory of the form 1. The roller 48 is mounted on horizontally raspolozene rolling copier 45 on the roller 48, the force of their interaction focused on the preload lever 47 to the stop 50, consequently, the frame 42 with the form 1 is rejected at the hinges 41, allowing the lugs 53 are raised form to bypass the stops adjacent form that is already installed in the previous step stacker on the second floor. In the lower part of the copier 45 angle to the working surface is selected so that the resultant of the force interaction roller 48 causes the lever 47 to rotate down and thus allow the possibility of deviating the frame 42 to begin to reverse the rotation around the hinge 41, until the contact of the front lugs 53 are raised form stops, standing on the second floor. Then the pusher delivers the bottom row forms a step forward, thereby summing another form under raised stacker shape. Thereafter, the hydraulic cylinder 40 stacker switch on the extension rod and the carriage 39 with deviant frame 42 is lowered to its original position. This raised form refuses on the second floor close to iterested. The stops 43, leaning up on its own hinges, round bottom shape and again stand on the supporting plate 44, and the lever 47 by the spring 49 is pressed against the plate 50, there is provided in its original position. The stacker is ready to rise following form.

Forms used in technological linetest, that form, standing on the second floor will be slightly longer than the lower forms. The accumulation of this difference can cause the back rest 53 top shape to protrude in the rear stop on the bottom of the form. In this case, the rise of the shape of the bottom row should be the deviation from the vertical trajectory, which were described above. If the value of the total accumulated error exceeds the value of the maximum deviations of the frame 42 of the pallet truck, the lines do pass one form without the upper floor, which allows you followed to install the stacker another form on the second floor with some initial offset forward relative to the bottom of the form, the value of which can be selected. This enables you again some time to work the stacker in nominal mode processing line.

The principle of operation of the lift allows you to adjust the cassette form and more than two tiers, while deviating frame raises two cassette form, flowing under them the next.

We offer stacker allows to increase the throughput of the heat treatment chamber, eliminating the need for a strict keeping of sizes shapes along their length, and also prevent the performance and smooth operation of the whole line.

Device for dispensing fluid works as follows. After filling the fluid supply tank 54 open solenoid valves 56 and 57 (Fig.8). When this solenoid valves 61 and 63 are closed. The liquid from the supply tank to the dispenser 57, and through the second pipe 58 and the solenoid valve 59 fills the pointer 60 of the liquid level in the supply tank 54. When the alignment of the liquid levels in the pointer 60 of the liquid level in the supply tank 54 to accurately set the volume of the dispenser is filled completely. After this, the solenoid valves 56 and 59 to close and open the solenoid valves 61 and 63. Through the electromagnetic valve 61 in the fuel line enters the air, which gives the opportunity to freely pouring the liquid from the metering device 57 through the electromagnetic valve 63.

The volume occasioanly fluid is determined by the internal volume of the hollow housing of the dispenser 57 and displacement of segments of highways connecting the dispenser to the solenoid valves 56, 59, 61, 63. This constant volume at a constant setting of the dispenser 57. Discharge valve 64 is designed to drain the fluid from the supply tank 54 when carrying out routine maintenance.

The volume of desire is through the support bracket 75.

When this hollow cylinder 69 is rigidly secured to the upper base of the Central nut 73 is raised or lowered along the vertical axis, simultaneously raising or lowering the limiter 77 on the scale 76 configuration of the dispenser. Outer 70 and 71 internal sleeve 71, which is placed between the stuffing box gasket 72, ensures the tightness of the volume of the hollow body 65 of the dispenser. Through pipe 66 is provided by the flow of fluid into the hollow body 65 of the dispenser, and the pipe 67 connects with pointer liquid level in the supply tank, and the flow of air from the discharge oldservername volume of liquid through the outlet 68.

Thus, the proposed device is excluded supply tank, which greatly simplifies the design. This is easily accomplished dosage relatively large volumes of fluid, as it does not require lifting / lowering of the dispenser. Increased precision and ease of control devices, highway which is equipped with an electromagnetic valve, and exclusion of the filling in each cycle dosage additional supply capacity, significantly reduces the time of dosing. The proposed line is equipped with two still the ode blocks in units and volume of output blocks according to the number of sections of the heat chamber, and other parameters at one, two, three and four-section of the heat chamber and shestnadtsatidnevnoy heat treatment. When the four chambers of the number of produced units per day is 1248 against 360 in one-section, which is sufficient for a continuous supply of construction of several to
