Abstract

The invention relates to a communal household, namely to silt machines, and can be used to clean water intake and manholes from mud and silt sediments. It makes it possible to increase the efficiency of the machine’s operation by creating a vacuum in the composite pipe 7 when the working reagent is fed under pressure to the nozzles of the ring holders 2 and 3 to loosen the sludge. Each annular cage is made with a distribution chamber for supplying air, which is connected to the cavities of the nozzles of the distribution chamber for supplying the working reagent via ejectors. In this case, the distribution chamber for supplying air through the pipeline 9 communicates with the cavity of the composite pipe 7 in its upper part. When the composite pipeline 7 is filled with the pulp, its cavity is disconnected from the air conduction system by means of a three-way switching valve 10 and air is drawn in from the atmosphere. 4 il. with S WITH

I The invention relates to a communal household, namely, the sludge kamHHaM, and can be used to clean water intake and manholes from mud and sludge deposits.

I The purpose of the invention is to improve the efficiency of the machine.

FIG. 1 shows the working body of the pumping machine, general view; in fig. 2 - ring holder, cut; FIG. 3 is a section A-A in FIG. 2; Fig. 4 is a connection diagram for a switching three-way valve.

The working body of the pumping machine consists of an end nozzle 1, in the lower part of which are arranged annular sleeves 2 and 3, in which a distribution chamber 4 is provided for supplying the working reagent and a distribution chamber 5 for supplying air to a group of nozzles 6 directed along the axis of the composite pipeline 7 side of the low face cut

end nozzle 1. In the annular cage 3, the nozzles 6 are directed at an acute angle away from the outer surface of the end nozzle 1 (not shown), h, then it increases the zone of hydrodynamic loosening of sediment. The composite pipe 7 in the upper part is connected to the distribution chamber 5, which is equipped with ejectors 8, one end of which is connected to it, and the other end to the cavities of the nozzles 6. In this case, their distribution chamber 4 is connected to a tank filled with liquid reagent (water, etc.). In addition, the other end of the ejectors faces the exit of the nozzles 6. The distributor to: Amer 5 is connected to the composite pipeline 7 by means of the pipeline 9, equipped with a three-way switching valve 10, and the distribution chamber 4 by means of the pipeline 11 to a container filled with liquid working reagent under pressure. The working unit of the pumping unit is lowered into the water intake well 12 by sludge 13. A collector 14 has been brought into and out of the well. The working unit of the pumping unit works as follows.

When cleaning wells and settling tanks with a compacted sludge, the end pipe 1 of the composite pipe 7 of the pumping machine is lowered onto the surface of the sludge 13. Through pipe 11 into the distribution chamber 4 is fed under pressure,

reagent, for example water.

Since the principle of interaction of the working reagent with the elements of the ring holders is similar, the further operation of the device is considered on the example of the ring holder 2.

The nozzle group 6 serves to hydrodynamically loosen sediment. The flow rate of the working reagent through them is sufficient to achieve minimum sludge mobility and to enter it into the composite pipe 7. From the distribution chamber 4, the liquid working reagent enters the nozzle group 6. Due to the flow

the ends of the ejectors 8 rapid high-pressure fluid flow vacuum occurs, which contributes to the suction of air from the cavity of the composite pipeline 7. The liquid from

The nozzles 6 are supplied with pulses, since when air enters them from the ejectors 8, the hydraulic modes change. This increases the effectiveness of loosening sludge and contributes to water saving. At the same time, the smallest air bubbles that fall into the liquefied liquid sludge adhere.

its particles. The process of flotation takes place, which contributes to

uniform distribution of sludge particles over the depth of a well filled with liquefied sludge. In addition, due to the suction of air from the composite pipe 7, a reduction is created in it, which allows increasing the volume of sludge from the well and increases the efficiency of the machine.

In the process of creating a vacuum

the slurry rises in the composite conduit. When filling the composite pipe 7 with pulp using a three-way switching valve 10, the cavity of the composite pipe is disconnected from the air pipe

water system and the intake of air comes from the atmosphere.
