The present invention relates to a vacuum drainage systems for sanitary facilities, such as toilets, urinals, sinks, etc., containing the by-pass pipe connected to sanitary facilities and communicating with the manifold, and the vacuum device is connected to the collector to create a vacuum in the pipes and transportation of sewage from sanitary equipment in precast Reutovo type are dominant when using them on ships, planes and trains. However, on land, such units are also widely used and conditions for this first of all is the low water use and flexible pipe systems for such systems.Known vacuum drainage system (1), in which the circulation pump is installed in the bypass pipeline and used for mixing, separating and aerating the contents of the tank or reservoir. The jet pump is connected, moreover, with by-pass piping and creates a vacuum in the drainage system. The jet pump is driven by a sewage circulating in the bypass pipeline under the action of the circulation pump. However, the main drawback of the circulation pump of the centrifugal type is that it is easily hammered textiles, accessories, sanitation, etc., which fall into the tank. In case of occlusion of the pump should be removed and cleaned, which leads to the cessation of his work and higher operating costs. In addition, one of the main disadvantages of these drainage systems is that they contain large, requiring a large space collection tank, which makes it unsuitable for use in equipment such as small vessels, where amused is as, because it uses two pumps, i.e., ink-jet and centrifugal pumps together with an additional bypass pipe and a collecting tank.The tank should have such dimensions and at any time to contain this amount of liquid (sewage), to eliminate foaming. Foaming due to the jet pump losing its pumping action, and practice has shown that even if supported by a large number of circulating fluid in the tank one way or another, in some cases, foaming is increased by the washing of toilets, from which the soapy water enters the tank.Known to the receiver system for vacuum drainage systems (2), which uses a vacuum tank with two chambers and a crusher with an individual drive. Sewage coming into the first chamber of the tank, are crushed and sent to the second chamber through the crusher. Vacuum pump, in particular a screw pump creates a vacuum in the tank and remove the contents of the second chamber outside the tank. Even if someone using the above system will be able to solve the problem of clogging and termination in connection with this work, the system remains relatively to the acquisition is the creation of a vacuum drainage system, which is devoid of the aforementioned drawbacks, i.e. which is:
is more compact and simple in construction and which therefore may be used on small boats in the automotive and residential houses, where frequent is the lack of space, but at the same time, system,
is cheaper to make,
has the safe operation and low operating costs,
has a high efficiency,
simply connected to the collecting tanks or wastewater treatment systems.the system eliminated the problems associated with foaming and loss of pumping ability.The technical result is achieved by the fact that in a vacuum drainage system for sanitary equipment: toilet bowls, urinals, sinks, etc. containing discharge piping connected to the sanitary-technical equipment and a collector, the device for creating a vacuum, connected in series in the direction of travel of the liquid comminuting device and a screw pump, in accordance with the invention connected in series in the direction of travel of the liquid comminuting device and a screw pump is made in the form of a block, with ismel what we disclosed in the dependent clauses. Their essence lies in the fact that the grinding device is made with stationary and rotating blades, while fixed blade installed at the entrance grinding device or a screw pump, and a rotating knife on the shaft of the screw pump.In addition, the system includes a separator with inlet and outlet pipe and the separator inlet pipe is connected to the collector, and the output to the input comminuting device and through a duct with the inlet of the screw pump.In Fig. 1 shows the side, front and top part of the drainage system of the present invention, containing a collection tank and a screw pump of Fig. 2 in an enlarged scale a longitudinal section of the screw pump shown in Fig. 1; Fig. 3 longitudinal section of the screw pump of a different design.In Fig. 1 shows a portion of the vacuum drainage system in accordance with the present invention, containing a collection tank 1 and two of the vacuum pump 2 connected in parallel. Pumps their outputs 3 is connected to the tank by means of connecting pipes 4 and they receive sewage from toilets and so on (not shown) of the manifold 5. At the outlet of each pump 2 installed air Sep'a is a great cross-section of one of the pumps, presented on Fig. 1. Pumps are pumps screw type and contain body 7 located in the inner screw 8 with bearings 9 and 10. On the input ends of the pumps installed chopping device or mill 11, comprising a housing 12 with a fixed knife 13 and the rotating knife 14. The body 12 of the mill has an inlet 15 with a flange to which is attached an air separator 6. Rotating knife 14 in the example shown mounted on the same shaft 16, and the screw 8, and is driven by a common motor (not shown). However, it should be noted that the knife, alternatively, may be mounted on a separate shaft and driven by a separate engine.The vacuum pump operates as follows.The vacuum switch is installed in the manifold 5 and includes a pump (works only one of the pumps when the pressure in the reservoir falls below the specified level. The air and impurities, supplied through the manifold 5, are separated in the separator 6, after which the air is directed, bypassing the mill, through the duct 17 and right at the entrance of the pump housing 18, while the sewage coming into the body of the mill through inlet 15. From the last impurity absorbed through the body 12 of the mill, JSC, as the impurity is again mixed with air in the inlet chamber 19 of the pump casing. Hence, sewage and air are sucked into in the axial direction through the housing 7 of the pump and then forced through the connecting pipe 4 in the tank 1.The tank 1 is provided with a separate pump 20 for draining the contents, the end 21 of the pipe with flange for connection to the pipe for irrigation (not shown), one end 22 of the pipe with flange for connection to the air duct (not shown) and an observation hatch 23. In addition, the side walls of the tank attached fuse box and the junction box 24. In this regard, it should be noted that if in the above description says that the pump 2 is connected with the tank 1, the invention is not limited to this example. Thus, the pump alternatively, may be connected with cleaning system, collecting system to public sewer, or if the vacuum drainage system is located on the vessel, directly overboard pipeline. Considering the above-described vacuum pump, it should be noted that air separator serves to reduce the velocity of the flow passing through it into the mill through the mill pass t is liczenie performance pumping. Thus, the pump separator is particularly suitable for large vacuum drainage systems that require high capacity feeder.An alternative design of the pump, is suitable, in particular, for small systems with small capacity feeder shown in Fig. 3. Except that the pump has no air separator, the design in the rest is the same as that of the pump shown in Fig. 2. It includes a housing 25 with an internal screw 26 mounted in bearings and mill 27 connected to the end of the pump housing. The mill includes a housing 28 within which is placed the fixed blade 30 and the rotary knife 29. The latter is installed on the same shaft 32, and the screw pump 26, and thus they are driven together using, for example, a not shown motor. At the entrance to the mill shell has a non-return valve 31, which prevents reverse flow of air and impurities in the suction pipe when the pump stops (vacuum is maintained in the suction pipe). Since the pump has no air separator, air and sewage is sent to the mill shell and forth in the axial direction through the pump. Otherwise, it works similarly to us is: toilets urinals, sinks, etc. containing discharge piping connected to the sanitary-technical equipment and a collector, the device for creating a vacuum, connected in series in the direction of travel of the liquid comminuting device and a screw pump, wherein connected in series in the direction of travel of the liquid comminuting device and a screw pump is made in the form of a block, with the chipping device is connected directly to the collector.2. The system under item 1, characterized in that the grinding device is made with stationary and rotating blades, while fixed blade installed at the entrance grinding device or a screw pump, and a rotating knife on the shaft of the screw pump.3. The system under item 1, characterized in that it is provided with a separator with the inlet and outlet nozzles, and the separator inlet pipe is connected to the collector, and the output to the input comminuting device and through a duct with the inlet of the screw pump.
