Description

BACKGROUND OF THE RELATED ART In-situ leaching of uranium is a very advanced mining technology in the world. Its basic principle is to arrange in-situ leaching mines for in-situ leaching sandstone-type uranium mines according to a certain mesh size, inject in-situ leaching solution from liquid injection wells, and make the in-situ leaching solution fully react with uranium ore to form a solution containing uranium ions, the solution containing uranium ions permeates through the stratum and enters the pumping wells, then the solution containing uranium ions is lifted out of the surface through the pumping wells, and uranium is further extracted in the surface factory. The existing descaling and cleaning methods for in-situ leaching uranium mines have the following shortcomings: Firstly, because the insertion depth of the air duct is about 50m below the liquid level in the well, it needs a large wind pressure to smoothly discharge the air in the air duct from the lower port of the air duct. Moreover, in the drainage process, a high-pressure air source needs to run continuously, and compressed air is fed into the air duct, which consumes a lot of energy; On the other hand, because the insertion depth of the air duct is about 200m below the liquid level in the well, it takes huge energy to push the waste liquid in the air duct to be discharged from the lower port of the air duct, which leads to the fact that the air flow discharged from the lower port of the air duct will not have great impact force, and it is difficult to wash the dirt firmly attached to the well wall; Secondly, because the lower port of the air duct is arranged downwards, the air flow discharged from the lower port of the air duct will firstly slow down and gush out, then slow up to zero, while the waste liquid to be discharged can only be transported to the wellhead by the rising air flow. In this case, the rising speed of the air flow is slow, and the transportation power provided is not strong, so it is difficult to transport the waste liquid to the upper section of the well quickly and 1

As shown in Figure 5-7, a method for discharging waste liquid from in-situ leaching uranium mines is applied to the intermittent inflatable in-situ leaching uranium mine waste liquid discharging device, which is used to discharge the cleaning waste liquid containing impurities from in-situ leaching uranium mines after the descaling operation is carried out in 7
DESCRIPTION LU102935 the in-situ leaching uranium mines. The steps are as follows: S01, connecting air duct and steel cable: a. The hanging tower and the air compressor are installed on the ground outside the wellhead of the in-situ uranium leaching mine 8, and the hanging tower includes a wire retractor 61 and two steel cables 62 connected to the lower end of the wire retractor 61; b. One end of the air duct 7 is connected to the air inlet, and the other end is connected to the air compressor; c. One end of the two steel cables 62 are respectively connected to the take-up and take-off device 61, and the other ends are respectively connected to the take-up and take-off device 61 after passing through the two perforations 1011 of the steel cable connecting pipe 10, after the connection, the two steel cables 62 are both U-shaped and symmetrically distributed on both sides of the air duct 7.
S02, lower the waste liquid discharge device: a. The take-up and take-off device 61 operates to pay out two steel cables 62 synchronously, so that the waste liquid discharge device can be gently put down through the wellhead of the in-situ uranium leaching mine 8; b. Every 50-60m, above the wellhead of the in-situ uranium leaching mine 8, a set of steel cable binding kit is fixedly installed outside the air duct 7 and the two steel cables 62, and the positions of the two steel cables 62 are constrained by the steel cable binding kit to prevent the steel cables 62 from rubbing against the shaft wall of the underground uranium mine; The size of the steel cable bundle kit is smaller than the inner diameter of the in-situ uranium leaching mine 8, which will not hinder the lowering process of the waste liquid discharging device; c. When the waste liquid discharging device is lowered to a predetermined depth, the take-up and take-off device 61 stops.
S03, inflating: When the air compressor is started, the compressed air enters the upper chamber 232 through the air duct 7, the air inlet 161, the gas-liquid channel 16 and the through hole 141 in turn, so that the pressure in the upper chamber 232 suddenly increases; The following four actions are triggered synchronously:
1. Part of the air and liquid in the upper chamber 232 is discharged through the upper hole 211, and the outflow direction is toward the upper part of the in-situ uranium leaching mine 8; 8
DESCRIPTION LU102935
2. The piston 3 is pushed by the sudden increasing pressure, and moves downward against the elastic force of the return spring 4, moving from the first position to the second position;
3. With the movement of the piston, the shaft wall sealing ring 5 changes from the contracted state to the expanded state, and the shaft wall of the in-situ leaching uranium mine 8 is closely contacted to cut off the underground uranium mine 8;
4. With the movement of the piston 3, the air and liquid in the lower chamber 231 are discharged from the lower chamber 231 through the lower hole 221, and the outflow direction is toward the lower part of the in-situ uranium leaching mine 8.
S04, stop gas: Pause the air compressor to stop the introduction of compressed air into the upper chamber 232, so that the pressure in the upper chamber 232 suddenly decreases to form negative pressure; The following four actions are triggered at the same time:
1. The piston 3 moves upward under the elastic force of the return spring 4 and moves from the second position to the first position;
2. With the movement of the piston 3, the shaft wall sealing ring 5 changes from the expanded state to the contracted state, so as to release the cut-off state of the uranium mine 8;
3. With the movement of the piston 3, the volume of the lower chamber 231 expands to form negative pressure. Under the negative pressure of the lower chamber 231, part of the waste liquid in the in-situ uranium leaching mine 8 enters the lower chamber 231 through the lower hole 221;
4. Under the negative pressure in the upper chamber 232, part of the waste liquid in the in-situ uranium leaching mine 8 enters the upper chamber 232 through the one-way valve 17, the water inlet 162, the gas-liquid channel 16 and the through hole 141 in turn, and then exits the upper chamber 232 from the upper hole 211 with the push of the piston 3, and the outflow direction is toward the upper part of the in-situ uranium leaching mine 8.
Repeat step S03-S04 to realize the continuous upward transportation of the waste liquid at a specific depth in the in-situ leaching uranium mine 8, and finally overflow from the wellhead of the in-situ leaching uranium mine 8.
In step SOI, the air duct 7 is a plastically deformable PE pipe. When the air duct 7 is connected, the port of the air duct 7 is screwed and installed on the external thread at the front end of the upper air duct 12. On the one hand, the upper air duct 12 expands to the port of the air duct 7 through the cone at the front end, which improves the connection tightness between 9
DESCRIPTION LU102935 the air duct 7 and the upper air duct 12, on the other hand, when the air duct 7 is twisted, the inner wall of the port of the air duct 7 rubs against the external thread at the front end of the upper vent pipe 12, so that an internal thread is molded on the inner wall of the port of the air duct 7, and the connection firmness between the air duct 7 and the upper vent pipe 12 is improved, On the other hand, when the air duct 7 is turned, the external wall of the port of the air duct 7 rubs against the internal thread at the front end of the air inlet sleeve 11, so that the external thread is molded on the external wall of the air duct 7, and the air duct 7 and the air inlet sleeve 11 are in threaded connection.
In step S02, when the waste liquid discharging device is lowered, the liquid in the in-situ uranium leaching mine 8 communicates with the air in the lower chamber 231 through the lower hole 221, and the air in the lower chamber 231 provides a certain buoyancy for the waste liquid discharging device, so as to reduce the load-bearing burden of the hanging tower.
In step S02, when the waste liquid discharging device is lowered, an annular gap is formed between the outer surface of the piston sleeve assembly and the wall of the in-situ leaching uranium mine 8, so the liquid at the upper end and the lower end of the waste liquid discharging device can be communicated through the annular gap in the in-situ leaching uranium mine 8.
In the step S02, because the waste liquid generated by cleaning the in-situ uranium leaching mine 8 is concentrated in the filter section, the lowering depth of the waste liquid discharging device is subject to the fact that the check valve 17 is 0-3m above the filter.
In step S02, as shown in Figure 8-9, the cable retracting kit includes a slotted plate 91 and a bolt 92. The groove plate 91 includes a U-shaped groove part and flanging parts connected to both sides of the U-shaped groove part, and the two flanging parts extend horizontally to the two outer sides of the U-shaped groove part respectively. The number of the groove plates 91 is two, and the two groove plates 91 are oppositely arranged, and are respectively connected at two groups of opposite turned-up parts by bolts, and two opposite U-shaped groove parts jointly form a constraint channel. When installing the cable retraction kit, two trough-shaped plates 91 are oppositely arranged around the outside of the air duct 7 and two U-shaped steel cables 62, so that the air duct 7 and the two steel cables 62 are contained in the restraint channel, then, bolts 92 are screwed into the two sets of opposite turned-up parts respectively, and the size of the restraint channel is changed by adjusting bolts 92, so that the U-shaped grooves of the two trough-shaped plates 91 press the air duct 7 and the two steel cables 62, so that the cable retraction kit can be fixedly installed outside the air 10
