Description

Technical Field

[0001] This invention relates to the field of coal mine well water purification technology, and in particular to a deep removal filtration device for suspended solids in coal mine well water. Background Technology

[0002] Coal mining generates a large amount of mine water, which is mixed with coal dust, rock powder, and oil leaks from underground equipment, resulting in a high concentration of suspended solids. If such high-concentration suspended solids are discharged directly, they can easily pollute surface water bodies, affect soil structure, and cause environmental problems. By filtering and treating the mine water, it can be transformed into usable water resources that can be reused for coal mine production, surface living, and greening, thus achieving the recycling of water resources.

[0003] Traditional coal mine water purification and filtration systems often use filter plates or filter cartridges to intercept suspended solids in wastewater. As the filter components gradually become saturated, their water flow capacity and filtration effect continuously decline. In order to maintain the continuous and efficient operation of the filtration device, it is usually necessary to manually disassemble, clean, or replace the filter cartridges after the machine is shut down. However, such operations will cause the filtration operation to be interrupted, affecting the progress of mine water treatment and the continuous supply of clean water. Summary of the Invention

The inlet pipe of the return pump is connected to the upper cavity inside the impurity collection box, and the outlet pipe of the return pump is connected to the right cavity inside the coal mine water separator.

[0006] Furthermore, a limiting screw is provided on the inner wall of the right insert, and the limiting screw is screwed to the filter cylinder limiting ring. An elastic guide cylinder is fixedly connected inside the filter cylinder limiting ring. An elastic push rod is slidably connected inside the elastic guide cylinder, and a reset spring is sleeved on the outer side. The two ends of the reset spring are respectively fixedly connected to the outer end of the elastic push rod and the outer end of the elastic guide cylinder. The left end of the elastic push rod is attached to the main filter cylinder.

[0007] Furthermore, the left edge of the left insert is fixedly connected to an insert flange, which fits against the left end face edge of the main filter cartridge.

[0008] Furthermore, the bottom of the coal mine water separator is fixedly connected to an excitation drive component, the upper end of the shaft of the excitation drive component is fixedly connected to an excitation disc, the side of the excitation disc is rotatably connected to an eccentric push wheel, the shaft of the excitation drive component is rotatably connected to a disc support, the left end of the disc support is fixedly connected to the coal mine water separator, and the edge of the excitation disc is attached to the left end face of the bottommost main filter cylinder.

[0013] Furthermore, two sealing plate top pillars are vertically welded to the upper surface of the sealing plate, with the upper section of the sealing plate top pillars fitting against the lower edge of the outer filter cartridge.

[0014] Furthermore, a conical guide cone is fixedly connected inside the opening of the outer filter cartridge, and the top of the guide cone has an opening.

[0015] This invention provides a deep removal and filtration device for suspended solids in coal mine well water, which has the following beneficial effects: This invention integrates multiple main filter cartridges into a filter cartridge assembly frame driven by a servo-positioning motor inside a coal mine water separator. The assembly frame is positioned between the left and right end plates. When a main filter cartridge requires cleaning due to suspended solids accumulation, the servo-positioning motor rotates the assembly frame to switch the cartridge to the corresponding position of the sealing push cover. The sealing push cover, pushed by a spiral cylinder, forms a sealed connection with the right end of the main filter cartridge. A transfer pump alters the water pressure inside the main filter cartridge via water flow, causing water from inside the coal mine water separator to flow backward through the main filter cartridge. This removes accumulated impurities adhering to the inner wall of the main filter cartridge and transports them to the impurity collection box, achieving rapid sludge removal from the main filter cartridge. The entire process requires no manual disassembly, significantly improving cleaning efficiency. Dynamic switching between filtration and cleaning positions can be achieved without stopping the machine, while the remaining main filter cartridges maintain their filtration state, ensuring the continuity of mine water treatment operations.

[0016] This invention features a filter cartridge self-cleaning module. When the impurities and water mixture generated during the cleaning of the main filter cartridge is transported to the bottom of the impurity collection box via a transfer pump, the wastewater enters the outer filter cartridge from the space below the partition of the collection box. As the wastewater passes through the outer filter cartridge wall, impurities are intercepted and further separated into solid and liquid components. The separated water is collected in the upper cavity of the impurity collection box and then sent back to the right cavity inside the coal mine water separator for further filtration via a return pump. This structure effectively reduces the amount of muddy water directly discharged, improves water resource utilization, and facilitates centralized collection and treatment of impurities. When the outer filter cartridge is saturated and needs cleaning, it is rotated and pulled out of the impurity collection box through the spiral assembly port. During this process, the sealing plate moves upward under the push of the sealing spring, sealing the bottom opening of the partition guide tube and closing the gap created by the removal of the outer filter cartridge. This prevents wastewater from leaking through the gap and flowing into the coal mine water separator. After a single outer filter cartridge is removed, impurities are continuously separated by another outer filter cartridge without interrupting the purification process, thus maintaining the continuous operation of the device.

[0017] This invention integrates filtration, switching, backwashing and sludge removal, and impurity concentration functions into one unit. The modules form a closed loop through pipelines and actuators, which can complete the filtration and self-cleaning cycle without relying on manual intervention. It is suitable for continuous treatment of coal mine well water. Attached Figure Description

[0023] Example 1: Please refer to Figures 1 to 13 : This invention proposes a deep filtration device for removing suspended solids from coal mine water, comprising: a suspended solids filtration module, including a coal mine water separator 1, a servo-positioning motor 2 installed on the left side of the coal mine water separator 1, and a filter cartridge assembly frame 3 installed inside; the filter cartridge assembly frame 3 includes an assembly frame shaft 301 and a left end plate 302 and a right end plate 303 fixed at its two ends, the assembly frame shaft 301 is connected to the coal mine water separator 1 through bearings and sealing rings, the servo-positioning motor 2 drives the assembly frame shaft 301, the right end plate 303 has four right inserts 304, the left end plate 302 has four left inserts 306, a main filter cartridge 4 is inserted between the right inserts 304 and the left inserts 306, the right end of the main filter cartridge 4 has an opening and the left end is sealed, the left end plate 302... A sealing ring is provided between the edge of the right end plate 303 and the inner wall of the coal mine water separator 1; a mine water inlet pipe 101 is installed at the right end of the coal mine water separator 1, and a clean water outlet pipe 102 is provided at the middle position above it; during the operation of the device, the valves of the pump body of the transfer pump 8 and the return pump 908 are closed, the mine water inlet pipe 101 is connected to the water pump, so that the coal mine water is sent into the coal mine water separator 1 through the mine water inlet pipe 101, enters the cavity to the right of the right end plate 303, and enters the main filter cylinder 4 through the right insert 304. Under the action of water pressure, it passes through the cylinder wall of the main filter cylinder 4. During the process, impurities are intercepted on the inner wall of the main filter cylinder 4. After passing through the main filter cylinder 4, the clean water is discharged through the clean water outlet pipe 102, thus realizing the purification of coal mine water.

[0024] In this embodiment, the filter cartridge self-cleaning module includes a spiral pusher 6 fixed to the right end of the coal mine water separator 1, a transfer pump 8, an impurity collection box 9, and a sealing push cover 7 located inside the coal mine water separator 1; the left end of the push rod of the spiral pusher 6 is fixedly connected to the sealing push cover 7; the input pipe of the transfer pump 8 is connected to the sealing push cover 7, and the output pipe is connected to the impurity collection box 9; the impurity collection box 9 is provided with a collection box partition 901, and the collection box partition 901 is provided with two partition guide tubes 902, which are inserted into the open end of the outer filter cartridge 10. The top of the outer filter cartridge 10 is threadedly connected to the spiral assembly port 903 at the top of the impurity collection box 9. A return pump 908 is provided on the left side of the impurity collection box 9, and the inlet pipe of the return pump 908 is connected to... The impurity collection box 9 is connected to the upper cavity inside the impurity collection box 9, and the outlet pipe of the return pump 908 is connected to the right cavity inside the coal mine water separator 1. When the impurity and water mixture generated by the main filter cartridge 4 is transported to the bottom of the impurity collection box 9 by the transfer pump 8, the sewage enters the outer filter cartridge 10 from the space below the partition plate 901 of the collection box. As the sewage passes through the wall of the outer filter cartridge 10, the impurities are intercepted and further separated into solid and liquid by the outer filter cartridge 10. The separated water is collected in the upper cavity of the impurity collection box 9 and sent back to the right cavity inside the coal mine water separator 1 by the return pump 908 for further filtration. This structure effectively reduces the amount of muddy water directly discharged, improves the water resource utilization rate, and also facilitates the centralized collection and treatment of impurities.

[0025] In this embodiment, a limiting screw 305 is provided on the inner wall of the right insert 304. The limiting screw 305 is screwed to the filter cartridge limiting ring 308. An elastic guide 309 is fixedly connected inside the filter cartridge limiting ring 308. An elastic push rod 310 is slidably connected inside the elastic guide 309. A return spring 311 is sleeved on the outer side. The two ends of the return spring 311 are fixedly connected to the outer ends of the elastic push rod 310 and the outer ends of the elastic guide 309, respectively. The left end of the elastic push rod 310 is attached to the main filter cartridge 4. An insert flange 307 is fixedly connected to the left edge of the left insert 306. The insert flange 307 is attached to the left end face edge of the main filter cartridge 4. The filter cartridge limiting ring 308 is assembled through the limiting screw 305. Under normal conditions, the main filter cartridge 4 is pushed to the left by the return spring 311 in conjunction with the elastic push rod 310, so that it is firmly installed in the filter cartridge assembly frame 3.

[0026] In this embodiment, a vibration drive component 5 is fixedly connected to the bottom of the coal mine water separator 1. A vibration disc 501 is fixedly connected to the upper end of the shaft of the vibration drive component 5. An eccentric pusher 502 is rotatably connected to the side of the vibration disc 501. A disc support 503 is rotatably connected to the shaft of the vibration drive component 5. The left end of the disc support 503 is fixedly connected to the coal mine water separator 1. The edge of the vibration disc 501 is attached to the left end face of the lowermost main filter cartridge 4. During cleaning of the outer filter cartridge 10, the vibration drive component 501 is... During the process of the transfer pump 8 causing impurities inside the main filter cartridge 4 to enter the impurity collection box 9 with the water flow, the excitation drive 5 is activated. The excitation drive 5 drives the excitation disc 501 to rotate. While the excitation disc 501 rotates at high speed, the eccentric pusher 502 impacts the main filter cartridge 4 at high frequency. Under the elastic action of the sealing push spring 905 and the pushing action of the eccentric pusher 502, the outer filter cartridge 10 is frequently moved laterally in small amplitude reciprocating motion, thereby causing the impurities firmly attached to the inner wall of the outer filter cartridge 10 to detach.

[0027] In this embodiment, the connecting pipe between the sealing push cover 7 and the transfer pump 8 is composed of a push cover guide pipe 701 and a fixed guide pipe 801 slidably connected. The push cover guide pipe 701 connects to the inside of the sealing push cover 7, and the fixed guide pipe 801 is fixedly connected to the right wall of the coal mine water separator 1. The lower end of the outer filter cartridge 10 is tightly inserted into the inside of the partition guide pipe 902. The lower end of the outer filter cartridge 10 has an opening and the upper end is sealed. Two vertical guide pillars 904 are vertically welded to the bottom of the impurity collection box 9. A sealing block plate 906 is sleeved on the upper part of the vertical guide pillars 904. Under normal conditions, when the outer filter cartridge 10 is working normally, due to the setting of the block plate top pillar 907, there is a gap between the sealing block plate 906 and the lower end of the partition guide pipe 902, and impurities and sewage can enter the outer filter cartridge 10 for separation.

[0028] In Example 2, based on Example 1, a sealing spring 905 is fitted over the vertical guide post 904. The bottom of the sealing spring 905 is fixedly connected to the impurity collection box 9, and the top of the sealing spring 905 is fixedly connected to the sealing block plate 906. Two block plate top posts 907 are vertically welded to the upper surface of the sealing block plate 906, and the upper section of the block plate top posts 907 fits against the lower edge of the outer filter cartridge 10. A conical guide cone 1002 is fixedly connected inside the opening of the outer filter cartridge 10, and the top of the guide cone 1002 has an opening. When the outer filter cartridge 10 is saturated and needs to be cleaned, the outer filter cartridge 10 is rotated to allow the impurities to pass through the spiral assembly port 903. The wastewater collection box 9 is pulled out. During this process, the sealing plate 906 moves upward under the push of the sealing spring 905, sealing the bottom opening of the partition guide tube 902. This seals the gap created after the outer filter cartridge 10 is pulled out, preventing sewage from leaking through the gap and flowing into the coal mine water separator 1. After a single outer filter cartridge 10 is pulled out, impurities are continuously separated by another outer filter cartridge 10 without interrupting the purification process, thus maintaining the continuous operation of the device. The guide cone 1002 prevents impurities in the water from returning to the wastewater collection box 9 through the bottom opening of the outer filter cartridge 10 during the extraction process.

[0029] The working principle of this embodiment is as follows: First, mine water is pressurized by a water pump and sent into the right cavity inside the coal mine water separator 1 through the mine water inlet pipe 101. Then, it enters the main filter cylinders 4 through the right insertion cylinder 304 on the right end plate 303. Under water pressure, the mine water passes through the cylinder wall of the main filter cylinder 4, and suspended solids are trapped on the inner wall of the main filter cylinder 4. The resulting clean water enters the space between the left end plate 302 and the right end plate 303, and is finally discharged through the clean water outlet pipe 102, thus achieving filtration and purification. When a lot of impurities accumulate on the inner wall of the main filter cylinder 4 and it needs to be cleaned, the servo shifting motor 2 drives the assembly frame shaft 301 to rotate the filter cylinder assembly frame 3, switching the main filter cylinder 4 to be cleaned to the position corresponding to the sealing push cover 7. Then, the spiral push cylinder 6 pushes the sealing push cover 7 to the left, sealing and connecting it with the right end of the main filter cylinder 4. After the transfer pump 8 starts, it extracts the mixture of impurities and water inside the main filter cylinder 4, which is then discharged through the push cover guide pipe 70. 1. The mixture is transported to the bottom of the impurity collection box 9 via the fixed conduit 801. After entering the outer filter cartridge 10, the mixture passes through the cylinder wall. Impurities are trapped inside the outer filter cartridge 10. The separated water rises to the upper cavity of the impurity collection box 9 and is then sent back to the right cavity inside the coal mine water separator 1 by the return pump 908 for further filtration, extending the manual cleaning and maintenance cycle. During the sludge discharge process, the excitation drive 5 drives the excitation disc 501 to rotate at high speed, and the eccentric push wheel 502 impacts the main filter cartridge 4 at high frequency, causing the impurities attached to the inner wall to fall off and improving the cleaning effect. When the outer filter cartridge 10 is saturated and needs to be replaced, the outer filter cartridge 10 is rotated to unscrew it from the spiral assembly port 903. The sealing plate 906 automatically moves up under the action of the sealing push spring 905 to seal the bottom opening of the partition guide tube 902, preventing sewage leakage. The other outer filter cartridge 10 continues to maintain normal separation operation, ensuring continuous operation of the device and realizing non-stop maintenance and cleaning of the device.
