Description

Technical Field

[0001] This invention relates to the field of in-situ leaching uranium mining technology, and in particular to a hose for lifting uranium leaching solution in in-situ leaching mining, as well as its preparation apparatus and method. Background Technology

[0002] In-situ leaching (ISL) is a uranium mining method that integrates mining, beneficiation, and smelting. It involves drilling and using chemical reagents to dissolve uranium from ore under natural burial conditions without displacing the ore. The process involves injecting a leaching agent underground, allowing it to flow through and soak the ore layer, then raising the uranium-bearing leachate to the surface. At the surface plant, the uranium is then recovered through hydrometallurgical separation.

[0003] In current in-situ leaching uranium mining processes, submersible pumps and associated rigid pipes are used to raise the underground leachate to the surface. The main body of this system is located most of the time hundreds of meters underground. When the submersible pump malfunctions or requires maintenance, pump raising and lowering operations are necessary. Existing domestic submersible pump raising and lowering systems mainly consist of a submersible pump, rigid HDPE pipes, threaded connections between the pump and the rigid pipe, metal clamps, safety ropes, and cables.

[0004] However, rigid pipes are bulky, heavy, costly, and difficult to rewind, which can easily cause the submersible pump to detach from the pipe. To solve this problem, an additional safety rope is usually required, but this takes up valuable working space inside the borehole. In addition, the safety rope is also prone to getting tangled with the power cable, causing inconvenience to operation and potentially causing pump or pipe jamming incidents.

[0005] Patent 202111560483.7 uses a flexible tube instead of a rigid tube, which has the advantages of being lightweight, flexible, and having a certain degree of extensibility. However, unlike the rigid tube, which is fixed with a flexible tube, how to fix flexible signal and power cables to the flexible tube with the above characteristics, and how to prevent them from getting tangled, has become a problem. Summary of the Invention

[0006] The purpose of this invention is to provide a hose for lifting uranium leaching solution in in-situ leaching, as well as its preparation device and method, which solves the problem of fixing hoses and cables and avoids entanglement between them under working conditions.

[0007] To achieve the above objectives, the present invention provides the following solution:

[0008] The present invention provides a hose for lifting uranium leaching solution from in-situ leaching, comprising a hose body, wherein a cable channel is formed on the side wall of the hose body, the cable channel extending axially along the hose body for cable passage.

[0009] Preferably, the hose body includes a strip layer, an inner hose layer, and an outer hose layer, wherein the inner hose layer and the outer hose layer are respectively attached to the inner and outer sides of the strip layer; wherein the strip layer is made of woven fibers, and the inner hose layer and the outer hose layer are both soft material layers.

[0013] The present invention also provides a device for preparing a hose for lifting uranium leaching solution from in-situ leaching, comprising a braiding machine, a conveying mechanism, a molding die, and an extruder. The braiding machine is used to braid a hose blank, the conveying mechanism is used to convey the hose blank to the molding die, and the extruder is used to inject heated hose material into the molding die, and the hose blank and the material are extruded together to form a hose body.

[0014] Preferably, the device further includes a metal strip roll, a conveyor roller, and a winding roller. The metal strip roll is disposed at the front end of the forming mold. A thin metal strip is wound around the metal strip roll. The conveyor roller is used to convey the thin metal strip to the winding roller. The winding roller is parallel to the hose body and extends into the forming mold. The winding roller is used to wind the thin metal strip multiple times to form a spiral metal armor, and to allow the spiral metal armor to enter the forming mold along with the winding roller to be formed together with the cable channel.

[0015] Preferably, it further includes a cooling mechanism and a collector, which are sequentially disposed at the rear end of the molding die. The cooling mechanism is used to cool the hose body after extrusion molding, and the collector is used to wind and collect the hose body.

[0016] Preferably, it further includes a cutting mechanism located between the cooling mechanism and the collector, for making spaced cuts in the cable channel to form openings.

[0017] The present invention also provides a method for preparing a hose for lifting uranium leaching solution from in-situ leaching, using the apparatus for preparing a hose for lifting uranium leaching solution from in-situ leaching as described above, comprising the following steps:

At the same time, a cable channel is formed on the side wall of the hose body. The cable channel extends along the axial direction of the hose body for the cable to pass through.

[0021] Preferably, in step S3, when extruding the hose body, the metal strip is conveyed to the winding roller by the conveyor roller. The winding roller is parallel to the hose body and extends into the forming mold. The winding roller winds the metal strip multiple times to form a spiral metal armor, and the spiral metal armor enters the forming mold along with the winding roller to be formed together with the cable channel.

[0022] Following step S3, the following step is also included:

[0023] S4. The extruded hose body is cooled by a cooling mechanism;

[0024] S5. An opening is formed by cutting the cable channel at intervals using a cutting mechanism;

The cable channel extends along the axial direction of the hose body for the cable to pass through, thereby solving the problem of fixing the hose and the cable and avoiding the two from getting tangled in the working environment.

[0028] Furthermore, the present invention integrally fabricates a spiral metal armor in the cable channel, which on the one hand can provide support for the cable channel, making it easier to insert cables into the cable channel, and on the other hand can shield signal noise for the signal cable; at the same time, the spiral armor structure can bend with the hose and has a certain degree of extensibility, which can better match the characteristics of the hose.

[0035] The purpose of this invention is to provide a hose for lifting uranium leaching solution in in-situ leaching, as well as its preparation device and method, which solves the problem of fixing hoses and cables and avoids entanglement between them under working conditions.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] like Figure 3 As shown, this embodiment provides a flexible hose for lifting uranium leaching solution from in-situ leaching, mainly comprising a hose body. A cable channel 15 is formed on the side wall of the hose body. The cable channel 15 extends along the axial direction of the hose body for the cable to pass through, thereby solving the problem of fixing the hose and cable and preventing them from tangling in the working environment. At the same time, there is no need to set an underwater protective sleeve for the cable itself. Moreover, the cable channel 15 extends along the axial direction of the hose body, so it will not be affected even if the hose body is flattened, and it is also convenient for the hose body to be wound and stored.

[0039] It should be further noted that the cables running through the cable channel 15 can be optical fibers, signal cables, and power cables used to supply power to devices such as pumps at the end of the hose.

[0040] In this embodiment, the hose body mainly includes a strip layer 53, an inner hose layer 52, and an outer hose layer 51. The inner hose layer 52 and the outer hose layer 51 are respectively attached to the inner and outer sides of the strip layer 53. The strip layer 53 is woven from fiber bundles, and the inner hose layer 52 and the outer hose layer 51 are both soft material layers, which can be made of rubber, plastic, or resin, etc.

[0041] In this embodiment, a spiral metal armor is provided inside the cable channel 15. The spiral metal armor is made of a thin metal strip 14 wound together with the cable channel 15 and formed together. The thin metal strip 14 can be steel strip, aluminum strip, or copper strip, etc. In this embodiment, the spiral metal armor can support the cable channel 15, making it easier to insert cables into the cable channel 15, and can also shield signal noise for the signal cable. At the same time, the spiral armor structure can bend with the body of the flexible hose and has a certain degree of extensibility, which can better match the characteristics of the flexible hose.

[0042] In this embodiment, an opening 16 is made at intervals along the length of the cable channel 15. When the flexible tube is too long, manual assistance can be used to thread the cable.

[0043] In this embodiment, multiple cable channels 15 may be provided on the side wall of the hose body, and all the cable channels 15 are evenly distributed along the circumference of the hose body; as a preferred embodiment, two cable channels 15 may be provided opposite to each other on both sides of the hose body.

[0044] like Figure 1 and Figure 2As shown, this embodiment also provides a device for preparing a hose for improving uranium leaching solution, mainly including a braiding machine 1, a conveying mechanism, a forming mold 7, and an extruder 6; wherein, the braiding machine 1 is preferably a vertical braiding machine, used to braid fiber bundles from multiple fiber rolls 2 into a hose strip blank 4; the conveying mechanism is preferably a conveying roller 3, used to convey the hose strip blank 4 to the forming mold 7; the feed port of the extruder 6 is connected to an injection funnel 5, and the hose material (the hose material is the soft material such as rubber, plastic, and resin mentioned above) from the injection funnel 5 is heated and injected into the forming mold 7 through the extruder 6, and is extruded together with the hose strip blank 4 to form a finished hose body, and a cable channel 15 is formed on the side wall of the hose body, the cable channel 15 extending along the axial direction of the hose body for the cable to pass through; wherein, the forming mold 7 is correspondingly configured to also integrally form the cable channel 15 along the axial direction on one or both sides of the hose body.

[0045] In this embodiment, it should also be noted that the hose blank 4 forms the blank layer 53 of the hose body, and the hose material forms the hose inner layer 52 and hose outer layer 51 of the hose body.

[0046] In this embodiment, the preparation apparatus further includes a metal strip roll 8, a conveyor roller 13, and a winding roller 12. The metal strip roll 8 is disposed at the front end of the forming mold 7. A thin metal strip 14 is wound on the metal strip roll 8. The conveyor roller 13 is used to convey the thin metal strip 14 to the winding roller 12. The winding roller 12 is parallel to the hose body. The winding roller 12 is a long roller that extends into the forming mold 7. The winding roller 12 is used to wind the thin metal strip 14 multiple times to form a spiral metal armor, and to allow the spiral metal armor to enter the forming mold 7 along with the winding roller 12 to be formed together with the cable channel 15.

[0047] In this embodiment, the preparation apparatus further includes a cooling mechanism and a collector 11, which are sequentially disposed at the rear end of the molding die 7. The cooling mechanism is used to cool the hose body after extrusion molding, and the collector 11 is used to wind and collect the cooled hose body.

[0048] In this embodiment, the preparation device further includes a cutting mechanism, which is used to cut an opening 16 in the cable channel 15 at intervals; wherein, the cutting mechanism is preferably a cutting head 9.

[0049] This embodiment also provides a method for preparing a flexible tube for lifting uranium leaching solution from in-situ leaching, using the preparation apparatus described above, specifically including the following steps:

[0050] S1. The fiber bundles from multiple fiber rolls 2 are braided into a hose strip blank 4 using the vertical braiding machine.

[0051] S2. The hose blank 4 is conveyed to the molding die 7 via the conveying mechanism;

[0052] S3. The heated hose material from the injection funnel 5 is injected into the molding die 7 through the extruder 6 and extruded together with the hose blank 4 to form the finished hose body. At the same time, a cable channel 15 is integrally formed along the axial direction on one or both sides of the hose body. The cable channel 15 is used for the cable to pass through.

[0053] In this embodiment, during step S3, when the hose body is extruded, the metal strip 14 wound on the metal strip roll 8 is conveyed to the winding roller 12 by the conveyor roller 13. The metal strip 14 is wound multiple times by the winding roller 12 to form a spiral metal armor, and the spiral metal armor enters the forming mold 7 along with the winding roller 12 to be formed together with the cable channel 15.

[0054] Following step S3, the following step is also included:

[0055] S4. The extruded hose body is cooled by a cooling mechanism;

[0056] S5. An opening 16 is formed by cutting the cooled cable channel 15 at intervals using a cutting mechanism;
