[0002] During the coal mining process, a large amount of wastewater containing suspended matter, heavy metals, oils and other pollutants will be generated. If it is discharged directly without effective treatment, it will cause serious pollution to the surrounding water bodies, soil and ecological environment.

The present invention provides a sedimentation tank and a filter tank, wherein sewage is injected into the sedimentation tank for sedimentation, larger debris and sludge are deposited at the bottom of the sedimentation tank, and the upper sewage is conveyed to the filter tank. When the sewage passes through the filter plate, the filter plate filters the fine particles of impurities and sludge in the sewage.

During long-term operation, the filter holes are easily clogged by impurities, resulting in a decrease in filtration efficiency, requiring frequent shutdowns for cleaning, and affecting the continuity of the treatment process. The filtration area of traditional devices is fixed and cannot dynamically adjust the effective filtration area according to the impurity accumulation situation, resulting in low filter material utilization and difficulty in improving the overall treatment efficiency of the equipment.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention relates to a highly efficient device for treating wastewater in a coal mining process. When treating wastewater generated in a coal mining process, the wastewater enters the filter cartridge from the water inlet pipe, and impurities are retained by the filter holes on the filter cartridge. As the impurities gradually accumulate, the filter holes are gradually blocked, and the pressure between the piston plates increases, thereby driving the piston plates to move away from each other. During the movement of the piston plates, filter holes that have not participated in the filtration will join the filtration behavior, thereby maintaining a good filtration effect at all times, and the filtered sewage is discharged along the drain pipe.

[0020] 2. The present invention describes an efficient device for treating wastewater in a coal mining process. The piston plate pushes the tooth plate to slide along the guide rod through the connecting rod. The synchronous gear drives a pair of tooth plates to slide synchronously while driving the connecting gear to rotate. The connecting gear drives the control gear to rotate and compresses the torsion spring. When the wastewater filtration is completed, the water pressure in the filter cartridge decreases, and the energy stored in the torsion spring drives the driving gear to reset. The driving gear cooperates with the connecting gear, the synchronous gear and the tooth plate to drive the connecting rod and the piston plate to reset. During the resetting process of the piston plate, the inner surface of the filter cartridge can be cleaned and the filtered residue can be squeezed into a filter cake, which is convenient for subsequent filtration and cleaning, thereby improving the wastewater treatment efficiency.

[0021] 3. The present invention relates to an efficient device for treating wastewater in a coal mining process. The positioning rod is inserted into the positioning hole and the connecting hole to fix the connecting rod to the tooth plate, so that the linear motion of the piston plate is transmitted to the tooth plate. When maintenance or cleaning of the filtered filter cake is required, the positioning rod can be pulled out to release the connection between the connecting rod and the tooth plate, which is convenient for disassembly, maintenance and cleaning.

[0043] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0044] like Figures 1 to 12 As shown, an efficient wastewater treatment device for coal mining according to an embodiment of the present invention includes a cylinder 10 supported by a support mechanism 20, cylinder covers 11 are provided at both ends of the cylinder 10, and a drainage pipe is provided on the cylinder cover 11;

[0045] The invention also includes a filtering and processing mechanism 30 disposed in the barrel 10. The filtering and processing mechanism 30 includes a water inlet pipe 31 fixedly mounted on the barrel 10. A filter cartridge 32 is fixedly mounted on one end of the water inlet pipe 31 located in the barrel 10. A pair of piston plates 33 are slidably mounted in the filter cartridge 32. A connecting rod 34 is fixedly mounted on the piston plate 33. The end of the connecting rod 34 away from the piston plate 33 is connected to the control assembly 40 via a connecting assembly 70.

[0046] The wiping assembly 50 provided on the control assembly 40 can wipe and clean the surface of the filter cartridge 32 and flush the filter holes after the filtration is completed.

[0047] When treating the wastewater generated during coal mining, the wastewater enters the filter cartridge 32 from the water inlet pipe 31, and impurities are intercepted by the filter holes on the filter cartridge 32. As the impurities gradually accumulate, the filter holes are gradually blocked, and the pressure between the piston plates 33 increases, thereby driving the piston plates 33 to move away from each other. During the movement of the piston plates 33, filter holes that have not participated in the filtration will join the filtration behavior, thereby maintaining a good filtration effect at all times, and the filtered sewage is discharged along the drain pipe.

[0048] The control assembly 40 includes a pair of guide rods 41 fixedly mounted on the inner wall of the cylinder 10, a toothed plate 42 being slidably mounted on the guide rods 41, a synchronous gear 43 cooperating with the toothed plate 42 being rotatably mounted on the cylinder 10, a connecting gear 44 being fixedly mounted on the synchronous gear 43, a pair of control gears 45 being rotatably mounted on the fixing ring 22, the control gears 45 cooperating with the connecting gears 44, and a torsion spring 46 connected to the control gears 45 being provided on the fixing ring 22;

[0049] The piston plate 33 pushes the tooth plate 42 to slide along the guide rod 41 through the connecting rod 34. The synchronous gear 43 drives a pair of tooth plates 42 to slide synchronously while driving the connecting gear 44 to rotate. The connecting gear 44 drives the control gear 45 to rotate and compresses the torsion spring 46. When the wastewater filtration is completed, the water pressure in the filter cylinder 32 is reduced, and the energy stored in the torsion spring 46 drives the driving gear to reset. The driving gear cooperates with the connecting gear 44, the synchronous gear 43 and the tooth plate 42 to drive the connecting rod 34 and the piston plate 33 to reset. During the resetting process of the piston plate 33, the inner surface of the filter cylinder 32 can be cleaned and the filtered residue can be squeezed into a filter cake, which is convenient for subsequent filtration and cleaning, thereby improving the wastewater treatment efficiency.

[0050] The connecting assembly 70 includes a connecting hole 71 formed on the tooth plate 42, a positioning hole 73 formed on the connecting rod 34, and a positioning rod 72 slidably mounted on the tooth plate 42 to cooperate with the positioning hole 73;

[0051] The positioning rod 72 is inserted into the positioning hole 73 and the connecting hole 71 to fix the connecting rod 34 to the tooth plate 42, so that the linear motion of the piston plate 33 is transmitted to the tooth plate 42. When maintenance or cleaning of the filtered filter cake is required, the positioning rod 72 can be pulled out to release the connection between the connecting rod 34 and the tooth plate 42, which is convenient for disassembly, maintenance and cleaning.

[0052] The wiping assembly 50 includes an outer ring 51 fixedly mounted on the tooth plate 42, an inner ring 52 rotatably mounted on the outer ring 51, and a threaded guide rail 53 is provided on the filter cartridge 32, and the inner ring 52 cooperates with the threaded guide rail 53;

[0053] After the filtration is completed, when the tooth plate 42 returns to its original position and slides, the outer ring 51 is driven to move, and the inner ring 52 moves and rotates due to the action of the threaded guide rail 53, so that the inner ring 52 wipes the outer surface of the filter cartridge 32 in a spiral manner to maintain a good filtration effect of the filter cartridge 32.

[0054] A conduit 54 is fixedly mounted on the tooth plate 42. The conduit 54 is in communication with the inner cavity of the tooth plate 42. A cavity is provided between the inner ring 52 and the outer ring 51. An end of the conduit 54 away from the tooth plate 42 is fixedly connected to the outer ring 51. The inner ring 52 is provided with a plurality of through holes 55.

[0055] When the piston plates 33 approach each other and drive the tooth plates 42 to move, the conduit 54 transports high-pressure water to the cavities of the outer ring 51 and the inner ring 52, and sprays it to the surface of the filter cartridge 32 through the through hole 55 of the inner ring 52. In conjunction with the rotation and movement of the inner ring 52, a composite cleaning mode of wiping and flushing is formed, which further improves the cleaning effect of the filter cartridge 32. During flushing, impurities in the filter holes can be flushed back into the filter cartridge 32 to prevent impurities from escaping between the cylinder body 10 and the filter cartridge 32.

[0056] The piston plate 33 is provided with a flip assembly 60, which includes a rotating disk 61 rotatably mounted on the piston plate 33, and a plurality of toggle plates 62 fixedly mounted on the rotating disk 61. The filter cartridge 32 is provided with a threaded groove 63 that cooperates with the rotating disk 61.

[0057] When the piston plate 33 slides, the rotating disk 61 moves and rotates due to the action of the threaded groove 63, driving the paddle plate 62 to stir the sewage, accelerating the sedimentation of large particles of impurities or the filtration of suspended particles. At the same time, when the piston plate 33 is reset to squeeze the impurities into filter cakes, the paddle plate 62 can paddle the impurities deposited at the bottom to improve the effect of pressing and forming the filter cakes.

[0058] The filter cartridge 32 is provided with a limit assembly 80, which includes a movable groove 81 provided on the filter cartridge 32, a movable block 82 being slidably mounted in the movable groove 81, and a lifting plate 83 being slidably mounted on the movable block 82;

[0059] When one end of the lifting plate 83 is located in the filter cartridge 32 , the movement range of the piston plate 33 can be limited, thereby preventing the piston plate 33 from being separated from the filter cartridge 32 and improving the filtering stability.

[0060] A pull rod 84 is fixedly mounted on the movable block 82, and a blocking block 85 is fixedly mounted on the pull rod 84. The blocking block 85 is slidably connected to the inner wall of the water inlet pipe 31;

[0061] When the piston plate 33 moves and contacts the lifting plate 83, it will drive the lifting plate 83 and the movable block 82 to move together. The movable block 82 drives the pull rod 84 and the blocking block 85 to move, blocking the water inlet pipe 31 and suspending water inlet so that the filter cartridge 32 can be cleaned.

[0062] The piston plate 33 is provided with a pressure sensor for detecting water pressure; the water pressure between the piston plates 33 can be detected so that the staff can understand the clogging condition of the filter cartridge 32.

[0063] The support mechanism 20 includes a mounting frame 21, on which a fixing ring 22 is rotatably mounted via a rotating shaft 23. The cylinder 10 is fixedly connected to the fixing ring 22. A sliding groove 24 is formed on the mounting frame 21, in which a slider 25 is slidably mounted. A latch 26 capable of being inserted into the rotating shaft 23 is fixedly mounted on the slider 25.

[0064] When the filter cake in the filter barrel 32 needs to be taken out, the sliding block 25 drives the pin 26 away from the rotating shaft 23, thereby releasing the restriction on the barrel 10. After removing the connecting rod 34, the piston plate 33 and the barrel cover 11, the barrel 10 is rotated to tilt it, and the filter cake in the filter barrel will fall due to gravity, thereby achieving a convenient and quick cleaning effect.

[0065] Working principle: When treating wastewater generated during coal mining, wastewater enters the filter cartridge 32 from the water inlet pipe 31. Impurities are trapped by the filter holes on the filter cartridge 32. As impurities gradually accumulate, the filter holes gradually become blocked, and the pressure between the piston plates 33 increases, thereby driving the piston plates 33 to move away from each other. During the movement of the piston plates 33, filter holes that were not involved in the filtration will participate in the filtration, thereby maintaining a good filtration effect at all times. The filtered sewage is discharged along the drain pipe;

[0066] The piston plate 33 pushes the tooth plate 42 to slide along the guide rod 41 through the connecting rod 34. The synchronous gear 43 drives the pair of tooth plates 42 to slide synchronously while driving the connecting gear 44 to rotate. The connecting gear 44 drives the control gear 45 to rotate and compresses the torsion spring 46. When the wastewater filtration is completed, the water pressure in the filter cartridge 32 is reduced, and the energy stored in the torsion spring 46 drives the driving gear to reset. The driving gear cooperates with the connecting gear 44, the synchronous gear 43 and the tooth plate 42 to drive the connecting rod 34 and the piston plate 33 to reset. During the resetting process of the piston plate 33, the inner surface of the filter cartridge 32 can be cleaned and the filtered residue can be squeezed into a filter cake, which is convenient for subsequent filtration and cleaning, thereby improving the wastewater treatment efficiency.

[0067] The positioning rod 72 is inserted into the positioning hole 73 and the connecting hole 71 to fix the connecting rod 34 to the tooth plate 42, so that the linear motion of the piston plate 33 is transmitted to the tooth plate 42. When maintenance or cleaning of the filtered filter cake is required, the positioning rod 72 can be pulled out to release the connection between the connecting rod 34 and the tooth plate 42, making it easier to disassemble, inspect and clean.

[0068] After the filtration is completed, the tooth plate 42 slides back to its original position, driving the outer ring 51 to move. The inner ring 52 rotates while moving due to the action of the threaded guide rail 53, so that the inner ring 52 wipes the outer surface of the filter cartridge 32 in a spiral manner, maintaining a good filtration effect of the filter cartridge 32.

[0069] When the piston plates 33 approach each other and drive the tooth plates 42 to move, the conduit 54 delivers high-pressure water to the cavities of the outer ring 51 and the inner ring 52, and sprays the water onto the surface of the filter cartridge 32 through the through hole 55 of the inner ring 52. In conjunction with the rotation and movement of the inner ring 52, a composite cleaning mode of wiping and flushing is formed, which further improves the cleaning effect of the filter cartridge 32. During flushing, impurities in the filter pores can be flushed back into the filter cartridge 32 to prevent the impurities from escaping between the cylinder body 10 and the filter cartridge 32.

[0070] When the piston plate 33 slides, the rotating disk 61 moves and rotates due to the action of the threaded groove 63, driving the toggle plate 62 to stir the sewage, accelerating the sedimentation of large particles of impurities or the filtration of suspended particles. At the same time, when the piston plate 33 returns to its original position to squeeze the impurities into a filter cake, the toggle plate 62 can pull up the impurities deposited at the bottom, thereby improving the effect of the filter cake pressing and forming;

[0071] When one end of the lifting plate 83 is located in the filter cartridge 32, the movement range of the piston plate 33 can be limited to prevent the piston plate 33 from being separated from the filter cartridge 32, thereby improving the filtering stability;

[0072] When the piston plate 33 moves and contacts the lifting plate 83, it drives the lifting plate 83 and the movable block 82 to move together. The movable block 82 drives the pull rod 84 and the blocking block 85 to move, blocking the water inlet pipe 31 and suspending water inflow so that the filter cartridge 32 can be cleaned.

[0073] When the filter cake in the filter barrel 32 needs to be taken out, the sliding block 25 drives the pin 26 away from the rotating shaft 23, thereby releasing the restriction on the barrel 10. After removing the connecting rod 34, the piston plate 33 and the barrel cover 11, the barrel 10 is rotated to tilt it, and the filter cake in the filter barrel will fall due to gravity, thereby achieving a convenient and quick cleaning effect.

[0074] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
