Abstract

The invention relates to the mining industry and makes it possible to increase the reliability of the installation. For this, the inlet chute (G) 2 of the settling tank 1 is made in the form of a U-shaped branch pipe with an expanding outlet part 3 and having an inlet regulator of the thickness of the layer in the form of a gate 4. At the junction of the lower part of the G 2 with the settling tank, a source of 5 sound vibrations is installed . It is made with a plate 6 floating above it. At the bottom of the sump 1, a discharge unit is installed in the form of a conical auger 8 with a check valve at the bottom in the form of an unloading hatch 13. The drilling fluid enriched with drill cutting is fed into G 2 through the gate 4 , Shieber 4 regulates the amount of incoming solution, and in the expanded part 3 G 2, its velocity is quenched. A thin layer of the solution is treated with ultrasound and enters the settling tank 1. The purified solution through the output G 18 with the filter screen 19 enters the next cleaning stage.

The invention relates to the mining industry and can be used in cleaning solutions from sludge.

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

FIG. 1 is a schematic diagram of the installation; in fig. 2 shows section A-A in FIG. one.

The installation consists of a settling tank 1 with an inlet chute 2, made in the form of an i-shaped nozzle with an expanding outlet part 3 and having a layer thickness regulator at the inlet, made in the form of a gate 4, and in the lower part of the inlet chute 2 at its junction with a sump 1 is equipped with a source 5 of sound vibrations made with a plate 6 floating above it. At the bottom of the sump 1, a conical case 7 of a discharge unit made in the form of an auger 8 with reverse is mounted on the flange connection

bearings 9 through the clutch 10 by an electric motor, a romotor 11. The pressed sludge is discharged into the container 12 through a check valve made in the form of a discharge hatch 13. The housing 7 has a perforated zone B.

The pressing force of the discharge port 13 to the flange of the side opening in the cone case is regulated by the degree of compression of the spring 14 with screws 15. The stop 16 serves to install the adjustment screws 15. Along the channel 17, the filtered solution is drained into the tank of the cleaning system. The source of ultrasonic vibrations is a magnetostriction transducer. The output of the chute 18 is blocked by a filter element 19.

Cleaning is as follows.

by force of strength. Large particles that have failed to settle in the upper layer are delayed by the filter screen 19.

The cleaned solution is continuously fed to the next cleaning stage, and the settled sludge in the cone housing 7 is periodically ejected by the cone auger when the electric motor 11 is turned on. The compressible condensed suspension consisting of solution and large sludge compresses until the compressive force becomes greater force generated by the springs 14 of the check valve.

When this condition is met, the discharge port 13 opens and the compacted sludge falls into the container 12. The compaction of the sludge is compressed by compressing the springs 14 with screws 15. The filtered solution flows through the gutter 17 in the circulation system tank through the holes in the cone housing. The perforated area of the housing starts from mark B to the discharge port. The frequency and duration of activation of the discharge / sealing means depends on the rate of accumulation of the thickened suspension of a certain concentration.

The use of a drilling mud treatment unit provides a twofold increase in productivity, a reduction in energy consumption for sound radiation and a loss of drilling mud by up to 30%, eliminating downtime during drilling when cleaning sumps.

Claims (3)

1. Installation for cleaning mud, including a sump with inlet and outlet chutes, source The drilling mud, enriched with 45 sound vibrations and a waste node, rented rock enters through the gate 4 into the inlet chute 2 of the settler 1. By regulating with the gate 4 the amount of the incoming solution into the expanded outlet part 3 of the U-shaped pipe (in the latter, the velocity is quenched), certain values of the velocity and thickness of the flow in the inlet groove 2. A thin layer of the solution is treated with ultrasound. The result of such processing sharply reduces the viscosity of the solution entering the settling tank 1, where the rock is effectively deposited under the installed in the bottom of the settler, characterized in that, in order to increase the reliability of operation, the inlet chute is filled the form i-shaped socket with an expanding outlet part and. has a layer regulator at the input, with the source of sound vibrations installed in the lower part of the inlet chute in place connect it with a settling tank and are made with a plate floating above it. 2. Installation according to claim 1, characterized in that the reg st torus jsfiHbi layer is made in the form of a gate. 312833534 3. Installing pop, 1, o tl and h a y- is made in the form of a conical auger with a pin, so that the waste unit is a check valve in the lower part.
