The invention further adopts the technical scheme that: the number of repeating unit segments is 1 segment.
Compared with the prior art, the invention has the following advantages:
1. the extracting method is used for extracting the leaching liquid under the deep water of the in-situ leaching uranium mine, can meet the requirement of pumping liquid flow rate of 6-10m < 3 >/h, and has the advantages of high pumping liquid flow rate, relatively low power consumption and relatively low cost compared with the traditional deep water submersible pump when the extracting depth is below 250 m.
2. In the process of recycling the extracting mechanism, the high-pressure air charging device charges air into the water pipe, the high-pressure air pushes the residual leaching liquid in the water pipe to flow downwards, and finally, the leaching liquid washes out a pressure release valve on the extracting mechanism to be discharged into an on-site uranium leaching mine; based on the above-mentioned operation of aerifing, on the one hand, the intraductal lixivium of water is replaced for the air, effectively reduced the weight of cable pipe complex, the cable pipe complex of being convenient for is convoluteed to the hoist engine, on the other hand, water pipe length can reach hundreds of meters, the intraductal remaining lixivium of water is great, intraductal remaining lixivium of water is discharged under the atmospheric pressure promotion in the on-site leaching uranium mine, avoided intraductal remaining lixivium of water to be wasted, on the other hand, the inside part lixivium of extracting mechanism is replaced for the air, provide certain buoyancy for extracting mechanism, effectively reduced the consumption of hoist engine recovery extracting mechanism.
3. Considering that the inside diameter of a ground-diameter uranium mine is narrow (the inside diameter of the well is smaller than 150 mm), when a waterway is designed, on one hand, space feasibility needs to be met as much as possible, and on the other hand, the cross-sectional area of water inlet and drainage needs to be enlarged as much as possible on the premise of meeting structural strength, so that an annular water cavity is designed in a section where an oil cylinder and a piston (comprising a piston A and a piston B) are arranged in a shell assembly for water drainage; the section of the water inlet (comprising a water inlet A, a water inlet B and a water inlet C) arranged outside the shell assembly is provided with a plurality of water inlet channels and water outlet channels which are annularly and uniformly distributed so as to supply water and discharge water. The waterway design is more fully utilized for the internal space of the shell assembly than the waterway design adopting a single water inlet and outlet channel, and can provide a relatively larger water inlet and outlet cross-sectional area.
4. The piston adopts a split threaded connection structure, so that the piston is convenient to install and assemble; two groups of Y-shaped sealing rings and one group of O-shaped sealing rings are arranged on the piston so as to fully meet the sealing requirement when the piston slides; the anti-abrasion ring is arranged in the middle of the piston, so that on one hand, the guiding effect of the piston in moving is achieved, on the other hand, the situation that the Y-shaped sealing ring is worn on one side to cause sealing failure is avoided, and on the other hand, the wearing probability of the piston body can be reduced, and a certain protection effect is achieved on the piston body.
5. When the number of the repeated unit sections is 1 section (as shown in the embodiment 1), the two-stage piston structure is adopted, and the experiment proves that the liquid pumping flow can reach 8m 3 And/h, the pumping flow rate can be 6-10m 3 Requirements of/h. When repeating unit segmentsWhen the number of the liquid pumping units is 2, the liquid pumping flow rate can reach 11m as proved by experiment determination 3 On one hand, the pressure in the annular water cavity is increased, the cavity walls on the two sides of the annular water cavity are correspondingly thickened, the overall radial dimension of the shell assembly is correspondingly increased, the space feasibility requirement is difficult to meet, on the other hand, the sealing performance of the sealing element is also higher, the grade and the cost of the sealing element are correspondingly increased, on the other hand, the force required by the oil cylinder during operation is also higher, the wall of the oil circuit pipeline is required to be designed thicker, the overall radial dimension of the shell assembly is correspondingly increased, and the space feasibility requirement is difficult to meet; in view of the above, it is most preferable that the number of repeating unit segments is 1 segment.
6. The application scene is an in-situ uranium mine with the well depth of 200-300m, the shell assembly bears larger water pressure, so that channels at all positions cannot be designed to be too thin (namely, the minimum requirement on the wall thickness of the channels is met), channel patterns based on central symmetry arrangement are adopted in the upper two-way communication section and the middle two-way communication section, and the number of water inlet channels and water outlet channels is respectively set to be four; based on the arrangement mode, on one hand, the full utilization of the inner space of the upper two-way communication section and the middle two-way communication section is realized, and relatively larger water inlet cross-sectional area and water outlet cross-sectional area are provided in a limited design space so as to expire the water inlet and outlet amount (6-10 m 3 On the other hand, this channel pattern based on a central symmetrical arrangement helps to keep the center of gravity of the housing assembly centered and stable during water lifting operations, avoiding lateral (radial) tilting of the housing assembly during water lifting operations or standing.
