Description

Technical Field

[0001] This invention relates to the field of water treatment equipment technology, specifically to a device and method for preventing and controlling geological water in coal mines. Background Technology

[0002] Coal mine geological water control is a core technical aspect of coal mine safety production. It mainly involves the dredging, filtration, and purification of water inflows and accumulations in coal mines. Underground mine water contains a large amount of solid impurities such as mud, sand, and ore fragments. Direct discharge can easily cause blockages and wear on pipelines and drainage equipment, as well as water and soil pollution, while also threatening the safety of underground mining operations. Therefore, the filtration, purification, and continuous treatment of mine water are key processes in coal mine geological water control. It is necessary to adapt to the complex and ever-changing water inflow conditions underground to ensure the stable, efficient, and continuous operation of mine drainage and water purification.

[0003] Existing coal mine geological water control and purification equipment has limited overall automation in mine water impurity purification operations. It cannot achieve fully automatic filtration, slag accumulation and slag discharge circulation operations. During equipment operation, staff need to periodically stop the machine to disassemble and clean the equipment to remove impurities. It is difficult to adapt to the large fluctuations in underground water inflow conditions and cannot continuously and stably complete the primary purification operation of mine water. During long-term operation, impurities are prone to accumulate, causing equipment blockage and failure. This not only reduces the overall purification efficiency of mine wastewater but also interrupts the water treatment operation process, affecting the continuity and stability of coal mine water control work. Summary of the Invention

[0004] The purpose of this invention is to address the limitations of existing coal mine geological water control and purification equipment in mine water purification operations. These equipment suffers from limited automation, failing to achieve fully automated filtration, slag accumulation, and slag discharge circulation. Furthermore, the equipment requires periodic shutdowns for disassembly and cleaning, making it unsuitable for the fluctuating water inflow conditions underground. Consequently, it cannot consistently and stably complete primary mine water purification operations, and long-term operation is prone to sluggish accumulation, leading to equipment blockages. This not only reduces the overall purification efficiency of mine wastewater but also interrupts the water treatment process, affecting the continuity and stability of coal mine water control. Therefore, this invention provides a coal mine geological water control device and method.

[0007] As a further embodiment of the present invention: the support columns are arranged in six groups, arranged in a circular array around the axis of the processing tank; the filter cylinder is conical with its tip pointing upwards, and the outer diameter of the bottom end of the filter cylinder is consistent with the inner diameter of the processing tank; the sealing sleeve is arranged in the moving groove, and the thickness of the sealing sleeve is consistent with the depth of the moving groove; the springs are arranged in five groups, arranged in a circular array around the axis of the processing tank on the inner side of the sealing sleeve.

[0008] As a further embodiment of the present invention: a magnetic ring 1 is embedded on the outer side of the sealing sleeve, and a magnetic ring 2 is embedded on the inner side of the moving groove. Two sets of magnetic ring 2 are provided and distributed above and below the discharge groove. The surfaces of magnetic ring 1 and magnetic ring 2 are opposite poles.

[0009] As a further embodiment of the present invention: the sealing component includes a sealing block fixedly connected to the bottom of the inner end of the connecting pipe, the top of the sealing block having a through groove, the center of the filter cylinder having a through hole, and a push block fixedly connected inside the through hole, the push block being arranged in four sets, symmetrically distributed inside the through hole.

[0010] As a further embodiment of the present invention: a connecting rod is provided through the through hole, the top end of the connecting rod passes through the first sealing block and extends into the first connecting pipe, and the top end of the connecting rod is fixedly connected to the second sealing block. The top end of the first sealing block and the bottom end of the second sealing block are rotatably connected. The top end of the second sealing block is provided with a second connecting groove. Both the first and second connecting grooves are fan-shaped and have the same size. There are two sets of both the first and second connecting grooves, which are symmetrically distributed around the axis of the connecting rod.

[0011] As a further embodiment of the present invention: the outer circular surface of the connecting rod is provided with a rotating groove, the rotating groove is spiral-shaped, and there are four sets of rotating grooves. Each set of push blocks is disposed in one set of rotating grooves and is engaged with the rotating groove.

[0012] A method for controlling geological water in coal mines includes the following steps: S1. First, after the equipment is started, the pump at the end of the drain pipe continuously generates negative pressure, which draws the turbid water containing mud, sand and ore fragments in the mine into the equipment through the inlet pipe. In the initial state, the filter elements of water purification component one and water purification component two are in the upper limit position, and the connecting groove one and connecting groove two of the sealing component are completely aligned and connected.

The following describes embodiments of the invention based on its overall structure.

[0018] Reference Figures 1 to 2 According to an embodiment of the present invention, a coal mine geological water control device and method includes: a water purification component 1 and a water purification component 2, wherein the water purification component 1 and the water purification component 2 are arranged in a straight line, and a water inlet pipe 3 is provided at the top of the water purification component 1 and the water purification component 2. One end of the water inlet pipe 3 extends into the mine shaft, and a drain pipe 4 is provided at the bottom of the water purification component 1 and the water purification component 2. A pump is provided at one end of the drain pipe 4. The end face of the water inlet pipe 3 facing the water purification component 2 is sealed, and the end face of the drain pipe 4 facing the water purification component 1 is sealed. Water purification component 1 includes a filter element 5 connected to the inlet pipe 3 and the outlet pipe 4. The filter element 5 is equipped with a sealing element 6 that cuts off the connection between the inlet pipe 3 and the filter element 5. Water purification component 2 has the same structure and size as water purification component 1.

[0019] Reference Figures 3 to 5The filter element 5 includes a treatment tank 51. A connecting pipe 1 52 and a connecting pipe 2 53 are respectively installed through the upper and lower ends of the treatment tank 51. The connecting pipe 1 52 is connected to the inlet pipe 3, and the connecting pipe 2 53 is connected to the drain pipe 4. A movable groove 54 is provided inside the movable groove 54, and a discharge groove 55 is provided inside the movable groove 54. Support columns 56 are fixedly connected to the inner side of the discharge groove 55 along its height direction. Six sets of support columns 56 are arranged in a circular array around the axis of the treatment tank 51. An installation ring 57 is fixedly connected to the inner side of the movable groove 54, and a filter cylinder 58 is fixedly connected to the top of the installation ring 57. Multiple sets of filter holes are evenly provided on the filter cylinder 58. The filter cartridge 58 is conical with its tip pointing upwards, and the outer diameter of the bottom end of the filter cartridge 58 is the same as the inner diameter of the processing tank 51. A sealing sleeve 59 is fixedly connected to the bottom end of the mounting ring 57. The sealing sleeve 59 is located within the moving groove 54, and its thickness is the same as the depth of the moving groove 54. A spring 510 is fixedly connected to the bottom end of the mounting ring 57. Five sets of springs 510 are arranged in a circular array around the axis of the processing tank 51, inside the sealing sleeve 59. A magnetic ring 1 is embedded on the outer side of the sealing sleeve 59, and a magnetic ring 2 is embedded inside the moving groove 54. Two sets of magnetic ring 2 are arranged above and below the discharge chute 55. The surfaces of magnetic ring 1 and magnetic ring 2 have opposite poles. In the initial state, [the following text is incomplete and requires further context: "..."] When spring 510 is extended, it lifts mounting ring 57 until the top of mounting ring 57 abuts against the top of the inner side of moving groove 54. At this time, magnetic ring one aligns with the upper set of magnetic ring two, forming a magnetic adsorption connection. As filtration proceeds, the amount of silt and mineral debris accumulating at the top of filter cylinder 58 increases. When the weight exceeds the sum of the elastic support force of spring 510 and the magnetic adsorption force of magnetic ring one and magnetic ring two, filter cylinder 58, mounting ring 57, and sealing sleeve 59 move downwards. The magnetic connection between magnetic ring one and the upper set of magnetic ring two is released, and spring 510 contracts under force until the bottom of sealing sleeve 59 abuts against the bottom of processing tank 51. At this time, the top of filter cylinder 58... The filter cylinder 58 is flush with the bottom of the discharge trough 55. The impurities filtered out at the top of the filter cylinder 58 are discharged to the outside of the treatment tank 51 through the discharge trough 55. During this process, magnetic ring 1 is aligned with a set of magnetic rings 2 located below and magnetically attracted together. Since the elastic force of spring 510 is less than the weight of the mud and ore debris accumulated at the top of the filter cylinder 58 and the sum of the magnetic attraction forces of magnetic ring 1 and magnetic ring 2, the filter cylinder 58 is kept in its current position. When most of the impurities at the top of the filter cylinder 58 are discharged, the pressure received by spring 510 decreases sharply until spring 510 overcomes the magnetic attraction forces of magnetic ring 1 and magnetic ring 2, returns to its original length, and drives the filter cylinder 58, mounting ring 57 and sealing sleeve 59 to move upward and reset.

[0020] The above solution involves setting up a complete filtration and purification structure, including water purification component 1, water purification component 2, inlet pipe 3, outlet pipe 4, and filter component 5. Relying on the adaptive linkage structure of spring 510 and magnetic ring, it achieves automatic filtration, slag accumulation, slag discharge, and reset cycle operation of mine water impurities. There is no need for manual shutdown to clean the equipment. It can continuously separate and purify pollutants such as mud, sand, and ore fragments in mine water, eliminating the drawbacks of traditional drainage equipment that only pumps water but does not purify it, and effectively improving the continuity and automation of mine water treatment.

[0021] Reference Figures 6 to 8 The sealing component 6 includes a sealing block 61 fixedly connected to the bottom of the connecting pipe 52. A connecting groove 62 is formed through the top of the sealing block 61. A through hole 63 is formed through the center of the filter cylinder 58. A push block 64 is fixedly connected inside the through hole 63. Four sets of push blocks 64 are symmetrically distributed inside the through hole 63. A connecting rod 67 is inserted through the through hole 63. The top of the connecting rod 67 passes through the sealing block 61 and extends into the connecting pipe 52. A second sealing block 65 is fixedly connected to the top of the connecting rod 67. The top of the sealing block 61 is rotatably connected to the bottom of the second sealing block 65. A connecting groove 66 is formed through the top of the second sealing block 65. The connecting groove 62 and the connecting pipe 58 are connected through the filter cylinder 58. All through slots 66 are fan-shaped and of the same size. There are two sets of connecting slots 62 and 66, symmetrically distributed around the axis of the connecting rod 67. The outer surface of the connecting rod 67 has a rotating slot 68, which is spiral in shape. There are four sets of rotating slots 68. Each set of push blocks 64 is set in one set of rotating slots 68 and engages with the rotating slot 68. When the filter cylinder 58 moves up to the limit position, the connecting slots 62 and 66 are aligned. When the filter cylinder 58 moves down to the limit position, the push blocks 64 move down synchronously. Under the engagement with the rotating slots 68, they push the connecting rod 67 to rotate, causing the connecting slots 62 and 66 to be misaligned, thus blocking the connecting pipe 52.

[0022] The above solution involves setting up a sealing block 61, a sealing block 65, a connecting rod 67, and a meshing transmission structure to match the sealing component 6. This allows for adaptive switching of the water flow opening and closing based on the working state of the filter component 5. During slag discharge operations, the water inlet passage is automatically blocked, preventing unpurified mine water from being directly discharged. This ensures that each batch of mine water is fully filtered and purified, effectively improving the purification accuracy of mine wastewater and preventing substandard water treatment.

[0023] The working principle of this invention is as follows: After the equipment is started, the pump at the end of the drain pipe 4 continuously provides negative pressure to draw the turbid mine water containing mud, sand, and ore fragments into the equipment through the inlet pipe 3. In the initial state, the filter elements 5 of both the first and second water purification components are in the upper limit working position, and the connecting groove 62 of the sealing component 6 is completely aligned with the connecting groove 66 of the second water purification component. The water circuits of the two sets of equipment are synchronously connected, and the mine water enters the two purification structures at the same time to carry out filtration. As water treatment continues, affected by water flow and impurity distribution, one set of equipment... The filter cartridge 58 of water purification component 1 first reaches the sludge accumulation threshold. For example, the weight of the accumulated impurities at the top of the filter cartridge 58 gradually exceeds the sum of the elastic support force of the spring 510 and the adsorption force of the magnetic ring. The filter cartridge 58, the mounting ring 57, and the sealing sleeve 59 move downward as a whole, compressing the spring 510 until the sealing sleeve 59 is in contact with the bottom of the treatment tank 51. During this process, the push block 64 moves downward synchronously with the filter structure. By engaging with the spiral rotating groove 68, it drives the connecting rod 67 to rotate. The connecting groove 1 62 and the connecting groove 2 66 are misaligned. The water passage of water purification component 1 is automatically blocked and enters the sludge discharge mode. At this time, water purification component 2... 2. If the slag accumulation standard is not met, the water path remains open and normal filtration and purification continues. It undertakes all mine water treatment work, ensuring uninterrupted operation of the entire equipment. After the impurities are discharged through the discharge chute 55, the load on the filter cylinder 58 decreases significantly. The spring 510 overcomes the magnetic ring's adsorption force, causing the overall structure to move upwards and reset. The water path of the sealing component 6 is reopened, and the water purification component 1 resumes filtration. Subsequently, the water purification component 2 continues to accumulate slag until the threshold is reached, repeating the entire process of downward movement, sealing, slag discharge, and reset. At this point, the process is switched to be handled solely by the water purification component 1. The filtration task is carried out by two sets of equipment in a continuous cycle according to this logic, naturally completing the alternating start and stop and the rotation of slag discharge, always maintaining the operation mode of one working and one standby. During the purification process, the mine water is screened by the conical filter cylinder 58, and solid impurities are intercepted. The clean water flows through the connecting pipe 2 53 and the drainage pipe 4 in sequence to complete the external discharge. This not only achieves efficient purification of mine water, but also reduces manual operation by utilizing the adaptive structure. At the same time, it avoids the leakage of turbid water during the slag discharge stage, ensures stable water quality, and reduces the wear of mud and sand debris on pumps and pipelines, taking into account the dual needs of drainage and water purification for geological water control in coal mines.The filter element 5 enables fully automated filtration of solid impurities in mine water, as well as the circulation of slag and wastewater discharge. This eliminates the need for manual shutdown and equipment disassembly for cleaning. It reliably intercepts pollutants such as mud, sand, and ore fragments in the mine water, continuously completing primary purification. Adapting to complex and variable water inflow conditions underground, it effectively ensures the continuity of mine water treatment operations, significantly improves mine wastewater purification efficiency, and reduces equipment blockage caused by impurity accumulation. The sealing element 6, relying on a linkage transmission structure, enables intelligent on / off control of the water circuit. It precisely matches the working state of the filter element 5, automatically blocking water inflow during the wastewater discharge stage to prevent the direct discharge of large amounts of unpurified, turbid mine water. This effectively avoids problems of incomplete water treatment and substandard water quality, significantly improving the precision of mine water purification and ensuring the standardization and stability of coal mine drainage and water purification operations.
