Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, and in particular to a direct filtration device for treating high-turbidity mine water. Background Technology
[0002] Mine water refers to water generated during the mining process, also known as mine runoff. Mine water is primarily generated from the natural infiltration of groundwater, the infiltration of surface water caused by climatic conditions (such as rainfall), and artificially introduced water (such as water from washing processes). Mine water typically contains large amounts of dissolved minerals, acidic substances, toxic and harmful substances, mineral dust, and rock fragments. Therefore, mine water must be properly managed and treated during mining operations. Treatment methods include pH adjustment, sedimentation, flocculation, filtration, adsorption, and biological treatment to meet discharge standards or for reuse.
[0003] A search revealed Chinese Patent Publication No. CN117566855A, which discloses an ultrafiltration direct filtration device for coal mine water treatment. The device includes a filter tank and an ultrafiltration tank connected by pipes. The filter tank comprises a tank body and a filter element installed within the tank body. The filter element includes a shell, a filter screen installed within the shell, a flushing pipe installed within the filter screen, a brush installed on the lower side of the outer wall of the filter screen, and a drain outlet on the inner wall of the shell. The flushing pipe has several layers of flushing pipes arranged at an angle; when the flushing liquid is discharged through the flushing pipes, it drives the flushing pipes to rotate, thus flushing the filter screen. The ultrafiltration tank includes a tank body and an ultrafiltration filter element installed within the tank body. The ultrafiltration filter element includes a shell, an ultrafiltration membrane installed within the shell, and an inlet pipe installed within the ultrafiltration membrane. The inlet pipe has several layers of outlet pipes arranged at an angle; when well water enters the ultrafiltration filter element through the outlet pipes, it drives the inlet pipe to rotate.
[0004] In most existing technologies, clean water is sprayed from inside the filter element to the outside to backwash and clean the filter element. However, the debris adhering to the filter pores cannot be directly impacted by the water flow, making it difficult to remove some tightly adhered debris during backwashing, thus affecting the cleaning efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a direct filtration device for treating high-turbidity mine water in order to solve the above-mentioned problems.
[0006] This utility model achieves the above objectives through the following technical solutions:
[0007] A direct filtration device for treating high-turbidity mine water includes a treatment cylinder. A cover is detachably connected to the top of the treatment cylinder. An inlet pipe and a drain pipe are fixedly connected to one side of the treatment cylinder. A drain pipe is fixedly connected to the bottom of the treatment cylinder. A groove is formed in the inner bottom wall of the treatment cylinder, and a filter cylinder is movably connected in the groove. The top of the filter cylinder extends out of the treatment cylinder. The drain pipe communicates with the inside of the filter cylinder. A backwashing component is installed inside the filter cylinder. An auxiliary mechanism is installed on the outer periphery of the filter cylinder. The auxiliary mechanism includes a second toothed ring rotatably connected to the top wall of the treatment cylinder. A connecting frame is provided at the bottom of the second toothed ring. A baffle is fixedly connected to the other end of the connecting frame. Several protrusions are fixedly connected to the side of the baffle near the filter cylinder. The auxiliary mechanism also includes a power component for driving the second toothed ring to rotate the baffle around the filter cylinder.
[0008] Preferably, the bottom of the second toothed ring is provided with a groove, the connecting frame is slidably connected in the groove, a spring is connected between the connecting frame and the groove, and several circumferentially arranged driving blocks are fixedly connected to the inner wall of the processing cylinder, and the connecting frame abuts against the driving blocks during rotation.
[0009] Preferably, the drive block is arc-shaped, and the corners of the connecting frame and the drive block that are close to each other are rounded.
[0010] Preferably, the power assembly includes a rotary motor fixedly connected to the top of the cover, the output end of the rotary motor is connected to a rotary shaft via a coupling, the bottom end of the rotary shaft extends into the processing cylinder and is fixedly connected to a second gear, the second gear meshing with a second gear ring.
[0011] Preferably, a first toothed ring is fixedly connected to the outside of the filter cartridge, and a first gear is fixedly connected to the rotating shaft, with the first gear meshing with the first toothed ring.

[0026] The present invention will be further described below with reference to the accompanying drawings:
[0027] like Figures 1-6 As shown, a direct filtration device for treating high-turbidity mine water includes a treatment cylinder 1. A cover 101 is detachably connected to the top of the treatment cylinder 1. An inlet pipe 102 and a drain pipe 104 are fixedly connected to one side of the treatment cylinder 1. The drain pipe 104 is located below the inlet pipe 102. A drain pipe 103 is fixedly connected to the bottom of the treatment cylinder 1. A groove is formed in the inner bottom wall of the treatment cylinder 1. A filter cylinder 2 is movably connected in the groove. The top of the filter cylinder 2 extends out of the treatment cylinder 1. A through hole is formed in the top of the treatment cylinder 1. The filter cylinder 2 extends out of the through hole. The drain pipe 103 communicates with the inside of the filter cylinder 2. Solenoid valves are installed inside the inlet pipe 102, the drain pipe 103, and the drain pipe 104.
[0028] The filter cartridge 2 is equipped with a backwashing assembly, which includes a backwashing pipe 105. The backwashing pipe 105 is fixedly connected to the cover 101. One end of the backwashing pipe 105 extends into the filter cartridge 2. Several water outlet holes located inside the filter cartridge 2 are opened around the backwashing pipe 105. The other end of the backwashing pipe 105 extends out of the cover 101. Under the action of the water pump, clean water is transported into the filter cartridge 2 through the backwashing pipe 105. Then, it is sprayed out from the inside of the filter cartridge 2 through the water outlet holes opened around the backwashing pipe 105, backwashing away the impurities filtered outside the filter cartridge 2.
[0029] An auxiliary mechanism is provided on the outer periphery of the filter cartridge 2. The auxiliary mechanism includes a second toothed ring 401 rotatably connected to the top wall of the inner wall of the processing cartridge 1. An L-shaped connecting frame 402 is provided at the bottom of the second toothed ring 401. A baffle 403 is fixedly connected to the other end of the connecting frame 402. Several protrusions 404 are fixedly connected to the side of the baffle 403 near the filter cartridge 2.
[0030] The bottom of the second toothed ring 401 is provided with a sliding groove, and the connecting frame 402 is slidably connected in the sliding groove. A spring 405 is fixedly connected between the connecting frame 402 and the sliding groove. Several circumferentially arranged driving blocks 406 are fixedly connected to the inner wall of the processing cylinder 1. During the rotation of the connecting frame 402, it abuts against the driving blocks 406. The driving blocks 406 are arc-shaped. The corners of the connecting frame 402 and the driving blocks 406 that are close to each other are rounded to improve the stability of the driving blocks 406 and the connecting frame 402 when they move relative to each other and to avoid jamming.
[0031] The auxiliary mechanism also includes a power assembly, which drives the second gear ring 401 to rotate the baffle 403 around the filter cylinder 2. The power assembly includes a rotary motor 407 bolted to the top of the cover 101. The output end of the rotary motor 407 is connected to a rotary shaft 408 via a coupling. The bottom end of the rotary shaft 408 extends into the processing cylinder 1 and is fixedly connected to a second gear 409. The second gear 409 meshes with the second gear ring 401.
[0032] The filter cartridge 2 is externally fixedly connected to a first toothed ring 301 located above the processing cylinder 1. A first gear 302 is fixedly connected to the rotating shaft 408. The first gear 302 meshes with the first toothed ring 301. The first toothed ring 301 and the first gear 302 mesh externally, while the second toothed ring 401 and the second gear 409 mesh internally, so that the rotation direction of the filter cartridge 2 is opposite to that of the baffle 403.
[0033] Working principle: During use, the mine water to be treated enters the treatment cylinder 1 through the inlet pipe 102 under the action of the water pump. The purified water after filtration through the filter cylinder 2 is discharged through the drain pipe 103. When it is necessary to clean the filter cylinder 2, the solenoid valves in the inlet pipe 102 and the drain pipe 103 are closed, and the solenoid valve in the drain pipe 104 is opened. Under the action of the water pump, the clean water is transported into the filter cylinder 2 through the backwash pipe 105. Then, the clean water is sprayed out from the inside of the filter cylinder 2 through the water outlet holes opened around the backwash pipe 105. The debris on the outside of the filter cartridge 2 is backflushed away, and the debris is discharged from the drain pipe 104 with the water flow. When the water sprayed from the filter cartridge 2 impacts the baffle 403, the protrusion 404 acts as a counterforce on the water flow, dispersing the water flow and causing it to backflush against the outer wall of the filter cartridge 2. This facilitates the removal of debris adhering to the outside of the filter cartridge 2, improving the cleaning effect. Simultaneously with the backflushing, the rotary motor 407 is activated, driving the rotary shaft 408 to rotate. The rotary shaft 408 then drives the second gear 409 to rotate. The second gear 409... The second toothed ring 401 engages, thereby driving the second toothed ring 401 to rotate. The second toothed ring 401 drives the connecting frame 402 to rotate the baffle 403 around the filter cartridge 2, improving the comprehensiveness of cleaning. During the rotation of the connecting frame 402, it will abut against the driving block 406. When the connecting frame 402 abuts against the driving block 406, the connecting frame 402 is squeezed by the driving block 406, driving the connecting frame 402 to move the baffle 403 closer to the filter cartridge 2. When the connecting frame 402 separates from the driving block 406, the connecting frame 402... Under the action of the spring 405, the baffle 403 is driven to move away from the filter cartridge 2, thereby adjusting the distance between the baffle 403 and the filter cartridge 2, increasing the range of water flow backwashing and improving the cleaning effect. At the same time, the rotating shaft 408 drives the first gear 302 to rotate. The first gear 302 meshes with the first gear ring 301, thereby driving the first gear ring 301 to drive the filter cartridge 2 to rotate in the opposite direction to the second gear ring 401, increasing the relative rotation speed between the filter cartridge 2 and the baffle 403 and improving the cleaning efficiency.
