Abstract

The invention relates to equipment for lowering the level of groundwater and stormwater in pits and underground workings. in particular, to devices for pumping out water and other liquids, preferably with solid inclusions. The invention is aimed at improving the efficiency and reliability. This is achieved in that a tilted shelf is attached to the wall above the bottom in the tank and sump. The spool attachment of the tank and sump is located under their inclined shelves, and the nozzle connecting the tank box with sump is attached to the bottom of the latter. In the process, the air coming out from under the shelves creates an intense movement of solid small and large inclusions. The shelves protect the spool devices from clogging and mechanical damage. 4 il.

The invention relates to equipment for lowering the level of groundwater and storm water in trenches and underground mines, in particular, devices for pumping water and other liquids, preferably with solid inclusions, and can be used in crushing and processing plants for cleaning sump.

The purpose of the invention is to increase efficiency and reliability in operation.

FIG. 1 shows a device for pumping liquids, a section; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 1. The device for pumping liquids has a reservoir 1 with overlap 2 and a bottom 3, inside of which a drainage pipe 4 is fixed, terminated with a connecting flange 5 and a transport line 6 from above, and a water intake funnel 7 at the top of tank 2, The cover 9 of which is equipped with a pressure switch 10, a sensor 11 of the upper level and an exhaust device 12, which consists of a housing 13, a clamp 14 and an elastic valve 15, which is mounted on one end of the hose 16, and the other on the stop 17. In the cover 9 hatch 8 in the center is mounted a pipe 18, and in a cover 14 a pipe 19 coaxially with it. On the side surface of the tank 1 there is a box 20 in which a connecting valve 21 is obliquely mounted above the lower end of the water intake funnel 7, at the end of which is an elastic valve 22, suspended by hinge 23. On the upper part of box 20 there is a process hatch 24 for installation and revision of valve 22.

In the lower part of the tank 1, an inclined shelf 25 is formed in parallel to its side wall, forming a gap 26 with the bottom 3. In the side wall of the tank 1, an air duct 28 with a slide valve 29 and a driving locking element 30 is connected through the hatch 27 under the inclined shelf 25, while the device 29 is located above the level of the lower edge of the shelf 25.

In the sump 31 with the receiving chute 32 and the protective conductor 33, an intermediate level sensor 35 is installed on the floor 34. In the lower part of the sump 31, a sloping shelf 36 is formed tightly attached to its side wall, forming a gap 38 with the bottom 37, and the bottom 37 is located at the top of the valve 22. The air duct 40 with the slide valve 41 and the driving locking element 42 is connected through the hatch 39 located also above the level of the lower edge of the shelf 36.

The device for pumping liquid works as follows.

Liquid, such as a mixture of flush effluent and spillage, and through the receiving chute 32 through the protective grating 33 enters the inclined SHELF 36 and the bottom 37.

As the sump 31 reaches the intermediate level 43 with a liquid, the intermediate level sensor 35, through an automatic control system (not shown), sends a signal to the actuating locking device 42, which, opening, supplies the compressed air to the air duct 40 to the slide valve 41. At the same time, under the inclined a shelf 36 forms an accumulation of air, which, when passing through the gap 38,

creates intensive mixing of solid small and large inclusions with liquid. Next, the mixed liquid through the connecting pipe 21 and the box 20 enters the tank 1. As the tank 1 is filled with air, air is forced out of it through the discharge box 12, the passage through pipe 18 around the valve 15 and pipe 19. When the liquid reaches level 44, the sensor 11 of the upper The level sends a signal through the control system to the opening of the locking element 30 for the supply of compressed air through the duct 28 to the spool device 29. In this case, under the inclined shelf 25, an accumulation of air is formed, which, through the gap 36, it intensively mixes the liquid with solid inclusions. When it rises above level 44, compressed air rapidly begins to exit through pipe 18 and jetly picks up valve 15, clamping it towards the end of pipe 19, and closing it. Collected compressed air at the top

The 0 part of the tank 1 creates pressure, while the valve 22 closes and the pressure increases so much that the changing liquid, together with the inclusions, rises through the water intake funnel 7 but in the sump pipe 4 to the transport main 6.

After pumping fluid from reservoir 1, the pressure in it decreases, pressure relay 10 triggers and sends a signal to close the actuator valve 30. At this, compressed air supply stops, valve 15 is lowered, opening pipe 19, and sump fluid 31 through open valve 22 fills tank 1.

After filling tank 1 to the upper level 44, the cycle is repeated.

5 Such an embodiment of a device for pumping a liquid allows pumping out a liquid with larger inclusions, and also protects spool devices from clogging and mechanical damage, which increases its efficiency and reliability in operation.
