The sludge separator 3 is covered by a receiving bunker 38, which is equipped with a discharge window 39.

The blades 13 in each volume formed by the conical plates 10 (the first and third sections) are combined into two separate impellers, with THOM the blades 13 of one impeller are located between the blades 13 of the other impeller. The blades 1 3 in the volume between the large bases of the conical plates 10 (in the second section) are combined into a separate impeller, and all the wheel arbors are fixed on the drive shaft 15, forming a common wheel 12.

Installation for cleaning the mine water collector works as follows.

Before starting operation, the knob of the manual current regulator 22 is set to the Closed position, in which the shell 18 completely overlaps the annular discharge gap 11 of the separator - sludge separator 3.

The switch 24 is set to the Manual unloading position for connecting the manual current regulator 22 to the winding of the electric control 26 of the pressure regulator 25. Shut-off valve 33 on the suction pipe 6 hydro 8225 closes

elevator 2 by remote control. With the aid of the nozzle 31, the outlet of the jetting unit 30 is closed. The valves are opened.

34 and 35. Through valve 34, water, for example, from a universal pipe, flows and fills the entire installation, and air flows out of it through valve 35. After the installation is filled with water

10 valves 34 and 35 are closed, the installation is ready for operation. The electric drive 9 is connected to the network, which drives the impeller 12 of the sludge separator 3 and the working body

t5 14 centrifugal pump 1. Pump 1 captures water from the volume of sludge separator 3 and delivers it to the hydraulic elevator 2 through the pressure pipe 4. After the speed of the electric drive 9 is set, the shut-off valve 33 in the suction pipe 6 of the hydraulic elevator 2 opens.

Due to the vacuum created in the mixing chamber (not indicated) of the hydraulic elevator 2, water is sucked through the screen 7, the shut-off valve 33 and the suction pipe. The conduit 6 from the mine water collector 36 and through the injection pipeline 5 is supplied to the volume of the sludge separator body 3 formed by the fixed conical plates 10 and the movable one. shell 18. Due to the rotation of the impeller 12 with blades 13 by the electric drive 9, the entrant in the sludge separator 3 - the separator mixture of water and sludge acquires a significant speed of rotational motion, which causes the action of centrifugal force. Under the action of centrifugal force, which exceeds the force of gravity several times, the mixture separates according to specific gravity. On the inner surfaces of the cones of the plates 10, due to the special implementation of the thumb wheel 12, the blades 12 are bent by a propeller in a given direction and angle — the slow streams of water-thinned sludge moving transverse to the plane of rotation are moving

towards each other in the middle part

the sludge separator 3, where the concentration of psham continues in the compacting sludge ring, and the clarified water forms a faster flow moving along the axis of the sludge separator 3 - separator into the inlet of pump 1, and then with pump 1 it is fed into the discharge pipe 4 to hydraulic elevator 2.

Pump 1 and hydraulic elevator 2 are the driving force of the flow, which is greater than the pressure in the flow. Excess water is discharged through the discharge valve 16 into the pipe 17. From the pressure pipe 4, the water is also supplied by the flexible hose 32 to the hydraulic monitor 30 of the slip ring 8. The flow rate of the jet of water from the monitor 30 is controlled by a step 31. The jet of water from the monitor 30 is used to stir up psham in the overflow channel 37, catchment 36, as well as wash them and the horizon (track) of the shaft.

The mixture of WATER and sludge is sucked in continuously by the jetting machine 2 and is supplied to the sludge separator 3 at a certain speed, due to which the unloading valve 16 is constantly in operation, providing automatic pressure regulation in the sludge separator body 3.

As the mixture of water and sludge enters the sludge separator 3, the tholium of the compacted sludge ring increases in the middle part of the sludge separator body 3 and its boundary begins to touch the blades 13 of the impeller 12 in its second section, which in turn increases the resistance to rotation of the impeller 12 and the electric current electric drive 9. To achieve a certain value of the current of electric drive 9, which is limited by a current meter, remote control is performed by discharging sludge from sludge separator 3. For this, the knob is a controller A manual current 22, for example, a selsyn-sensor, is set to the Open position, which causes a certain voltage to be output at the output of the manual current regulator 22. This voltage is supplied through the current switch 24 to the coil 26 of the electric etching of the pressure regulator 25. According to the effective voltage at the output of current regulator 12, the movable bore of pressure regulator 25 occupies a certain position in the electric control winding 26 and simultaneously changes the position of the spool in the flow control working chamber, which determines in turn the pressure of the working medium, such as compressed air, at the outlet 28 transmission of adjustable pressure from the inlet. 27 Receives982256

of the working medium and the pressure in the power cylinders I9 of the drive of the shell 18. In this case, the pistons with the rods 21 are proportional to the setting pressure in the cylinders 19 move and shift the movable shell 18, which relative to the lower conical plate 10 forms a discharge ring slot 11, the size corresponding to the actual pressure value working medium in cylinders 19.

Thus, a certain current in the winding 26 of the electric control of the regulator, pressure torch 25, coming from the manual control current regulator 22 is determined by a certain size of the discharge gap 11 for discharging sludge from the sludge separator 3.

20 Sludge removal occurs simultaneously with the entry of a mixture of water and sludge into the sludge separator 3. During sludge discharge, the thickness of the sludge ring gradually decreases and, finally, its boundary goes beyond the blades -13 of the impeller 12 into its second section. The resistance to rotation of the impeller decreases, and the current of the electric drive 9 decreases. According to the reading of the current meter, it is determined that it is necessary to close the discharge gap AND, for which the knob of the manual current regulator 22 is set to the Closed position, which

5 turn leads to change

voltages in the winding 26 of the electric control, a decrease in the pressure of the working medium in the cylinders 19 and a return. shell 18 due to compressed energy

0 springs to a position in which the discharge gap 11 is closed. Then, due to the continuous flow of the mixture of water and sludge into the sludge department: itel 3, the boundary of the sludge ring moves again to the straight blades 13 of the knife 12, and the cycle of the sludge discharge control unit is repeated.

If automatic sludge discharge control is required, the switch 24 is set to the Automatic discharge position. In this case, the current controller 22 is turned off.

and an automatic control current regulator 23 is connected to the winding 26 of the electric control of the pressure regulator 25. When the boundary of the slurry ring 7 reaches the straight blades 13 of the impeller 12, the current in the circuit of the electric drive 9 increases, according to which the shunt in the circuit of the electric drive 9 and the current amplifier provide a certain amount of voltage to the winding 26 of the electric control. In proportion to the voltage, the pressure of the working medium in the power cylinders 19 of the shell 18 is moved, the shell 18 moves to open the discharge gap 11. Leaving the border of the slurry ring from the blades 13 in the second section of the wing 12 reduces the current in the drive circuit 9, changing the voltage in the circuit of the winding 26 of the electric control and overloading of the annular discharge gap 11 by the ring 18. Thus, the opening and closing 258 of the discharge gap 11 automatically proceeds from the current value of the electric drive 9 bechaykoy sludge discharge control unit allows due to the gap between the vanes 13 of the impeller 12, the movable shell 18 to close the annular discharge slit 11 prior to the ejection of water from the sludge. Discharged through the discharge gap 1 1 of the separator 3, the sludge enters the receiving hopper 38 and through its discharge opening 39 goes, for example, for further processing. In the separated sludge separator 3 there is always some water left, which can be removed permanently by drying or, for example, in the process of briquetting the sludge - mixing it with the holding material, followed by pressing and cutting the briquettes and holding them to crystallization.
