The invention relates to the dewatering of pits and mines, can be used in the extraction of gravel and sandy materials in water bodies and is an improvement of the invention according to the author. No. 775233.

The purpose of the invention is to increase productivity and reliability by eliminating water hammer in the pressure head.

The drawing shows the device, re; Alizing the proposed cleaning method; mine water collectors from sludge.

The device consists of supplying working fluid water to the hydraulic elevator 1 of the pipeline 2, one end of which is connected through the valve 3 to the discharge pipe of the basic pump unit 4 below the controlled valve 5, and the other to the hydraulic elevator nozzle 1. One suction pipe 6 of the hydraulic elevator 1 the end is connected to a vacuum chamber of a hydraulic elevator, the other to a soil intake confuser embedded in a hydraulic substage 7. The diffuser of hydraulic elevator 1 is connected to two (and more) parallel drain pipelines 8 and 9, each The first of which is connected to the pressure pipe 10 at one end and has bridges with controlled taps 11 and 12 between them. Exhaust pipe 13 is connected to valve 12 and pipe 2 is connected to valve 12. At the junction of pipelines .8 and 9 with hydraulic elevator 1 a controlled valve 14 is installed, and before connecting them to the pipeline, 10-check valves 15 and 16. The controlled valves 11, 12 and 14 serve to alternately distribute the flow of the slurry and pressurized water.

The method using the device is as follows.

During normal operation, clean water is pumped from the reservoir'17 to the sludge trap (to the surface) when the controlled valve 3 and check valves 15 and 16 are closed and the valve 5 is open.

When working to remove sludge from a hydroliver 7, a device implementing the method, and an automatic process control system, ensuring the operation of the hydraulic elevator 1 for removing the sludge from the hydrolabber 7 with alternate connection of the respective drain pipelines 8 and 9, are put into operation.

When cleaning the water collector, the controlled valve 4 is opened, the handles of the valves 11 and 12 are rotated, for example, counterclockwise, when the atomizer 5 and the check valve 16 are closed, and the handle of the controlled valve 14 is turned clockwise. In this position of the shut-off valve, water from the operating pump 4 comes through pipeline 2 and pipelines 9 and Hume simultaneously and the nozzle of the elevator 25 of elevator 1. flows through it into the diffuser, then through edge 14 and drain pipe into the worm operated valve 11 into pipeline 13. In its time, the GMDrozleator 1 begins to suck in the sludge from the hydro * 30 bottom 7 worm pipeline b. After a specified time, the drain pipe 8 is filled with pulp formed by hydraulic elevator 1, when the atom automatically switches the controlled 35 taps 11,12 and 14. During operation, water is pumped through the hydraulic line: pump 4, open valve 3, discharge pipe 2, controlled faucet 12, drain pipe 8, non-return valve 40 valve 15, pressure valve becoming 10 (valve 5 is closed). Simultaneously pressurized water

the lower branch of the pipeline 2 is fed to the nozzle of the hydraulic elevator 1 and then through the controlled valve 14, the drain pipe 8, the controlled valve 11 in the exhaust pipe 13 to the discharge. As a result, the drain pipe 8 is freed from the pulp, and the drain pipe 9 is filled with pulp. At this cycle of transportation of sludge from hydrosaw 7 to the pressure head 10 and then to the dump is completed.

The next cycle is performed in the same sequence. The presence of two or more discharge pipelines connected in parallel eliminates the effect of inertial phenomena of a liquid column (sludge) in a pressure head.

The use of the proposed method for cleaning mine sludges and other mountain workings from sludge and oozy deposits, as well as for extracting gravel-sandy materials in water bodies from large depths, allows to work more economically and efficiently, to increase the service life of the base pump, to reduce labor costs and to operate drainage and development of deposits in the underwater way.
