Technical Field
[0001] This utility model relates to the field of water pollution control technology, specifically to a solid-liquid separation device for water pollution control. Background Technology
[0002] Water pollution prevention and control refers to the prevention and treatment of water pollution caused by the introduction of certain substances, which alters the chemical, physical, biological, or radioactive properties of water bodies, thereby affecting the effective use of water, endangering human health, or damaging the ecological environment, and causing water quality deterioration. In the process of water pollution prevention and control, solid-liquid separation devices are needed to treat the already polluted water in order to facilitate further purification treatment.
[0003] Based on the above, the inventors have discovered the following problems: Current solid-liquid separation devices generally use a filter plate inside the housing as the core separation component. In actual use, wastewater directly impacts the surface of the filter plate, achieving solid-liquid separation through the densely distributed filter holes. Solid impurities are intercepted on the surface of the filter plate. As the amount of wastewater increases, solid impurities accumulate on the filter plate, easily clogging the filter holes and reducing wastewater throughput. Current solid-liquid separation devices are not convenient for flushing and cleaning clogged filter holes, thus reducing the practicality of the solid-liquid separation device.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a solid-liquid separation device for water pollution prevention and control, in order to achieve a more practical value. Utility Model Content
[0005] The purpose of this invention is to provide a solid-liquid separation device for water pollution control, so as to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A solid-liquid separation device for water pollution control includes a placement component, a separation component, and a flushing component. The separation component and the flushing component are respectively disposed on both sides inside the placement component. The separation component is used for solid-liquid separation of sewage, and the flushing component is used for flushing the separation cylinder. The placement component includes a box body, and a circular cavity and a U-shaped cavity are respectively opened on both sides inside the box body. The flushing component includes a partition plate, the outer wall of which is fixedly connected to the inner wall of the U-shaped cavity. A rotating groove is opened inside the partition plate, and a circular connecting plate is rotatably connected inside the rotating groove. A flushing head is connected to one side of the top surface of the circular connecting plate, and a connecting seat is connected to the bottom end of the circular connecting plate. A compressed air inlet pipe is connected to the bottom end of the connecting seat. The compressed air inlet pipe extends through the box body to the outside at the end away from the connecting seat, and the outer wall of the compressed air inlet pipe is clearance-fitted with the inner wall of the through hole of the box body.
[0008] Furthermore, the bottom end of the connecting seat is connected to the inner bottom end of the U-shaped cavity via a bearing, and a toothed ring is sleeved on the outside of the connecting seat. A second servo motor is installed at the bottom end of the housing near the compressed air inlet pipe. The output end of the second servo motor extends through the housing into the interior of the U-shaped cavity. A gear is connected to the output end of the second servo motor, and the gear meshes with the toothed ring.
[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of the second servo motor, gear and gear ring, since the bottom end of the connecting seat is connected to the bottom end of the U-shaped cavity through the bearing, when the second servo motor works, it drives the gear to rotate, the gear meshes with the gear ring to drive the connecting seat to rotate, and then causes the circular connecting plate and the flushing head to rotate, thereby realizing the all-round flushing of the separation cylinder, improving the flushing efficiency and effect.
[0010] Furthermore, the top surface of the housing is provided with a first limiting ring groove and a second limiting ring groove on both sides. The separation component includes a limiting ring plate, which is disposed in the first limiting ring groove. A hollow ring is rotatably connected inside the limiting ring plate. A separation cylinder is slidably disposed inside the hollow ring. The outer wall of the separation cylinder is provided with four sliding grooves. Each of the four sliding grooves is provided with a slider near its upper end. The outer walls of the four sliders are slidably engaged with the inner walls of the four sliding grooves. The outer walls of the four sliders are fixedly connected to the inner walls of the hollow ring. The outside of the separation cylinder is provided with several micro-filter holes. The bottom end of the separation cylinder is provided with a circular hole, and a strong magnet is installed inside the circular hole.
[0011] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the limiting ring plate, the first limiting ring groove, the second limiting ring groove, the hollow ring plate, and the separation cylinder, the separation cylinder is inserted into the circular cavity with the cylinder opening facing upwards and the limiting ring plate located inside the first limiting ring groove. When the separation cylinder rotates inside the hollow ring plate, the micro-filter holes on the separation cylinder can achieve solid-liquid separation. Through the combined use of the sliding groove and the slider, after the solid-liquid separation is completed, the user takes out the separation cylinder and inverts it so that the hollow ring plate and the limiting ring plate are located at the end of the separation cylinder where the strong magnet is installed. The separation cylinder is then inserted into the U-shaped cavity with the cylinder opening facing downwards and the limiting ring plate located inside the second limiting ring groove.
[0012] Furthermore, a waterproof seat is connected to the bottom of the inner cavity of the circular cavity, and a turntable is rotatably connected to the top surface of the waterproof seat. A groove is formed on the top surface of the turntable, and a waterproof electromagnet is connected inside the groove. The waterproof electromagnet is magnetically attracted to a strong magnet. A first servo motor is installed at the bottom of the inner cavity of the waterproof seat. The output end of the first servo motor passes through the waterproof seat and is fixedly connected to the bottom of the turntable.
[0013] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the first servo motor, turntable, waterproof electromagnet and strong magnet, the waterproof electromagnet is energized, causing it to attract the strong magnet. Then, when the first servo motor works, it drives the turntable to rotate. Under the attraction of the waterproof electromagnet and the strong magnet, the separation cylinder rotates, realizing the solid-liquid separation of sewage in the separation cylinder. The waterproof electromagnet adopts special waterproof sealing technology, such as rubber or silicone sealing rings, special coatings or welding seals, to ensure that the electromagnetic coil and magnet components are completely sealed, preventing the intrusion of water and moisture.
[0014] Furthermore, the limiting ring plate is composed of a ring plate and four limiting strips on the outer wall of the ring plate. The inner walls of the first limiting ring groove and the second limiting ring groove are respectively clearance-fitted with the outer wall of the limiting ring plate. The first limiting ring groove is connected to the circular cavity, and the second limiting ring groove is connected to the U-shaped cavity.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the limiting ring plate is composed of a ring plate and four limiting strips, and the outer wall of the limiting ring plate is in clearance fit with the first limiting ring groove and the second limiting ring groove, so that the separation cylinder is placed stably. Since the first limiting ring groove is connected to the circular cavity and the second limiting ring groove is connected to the U-shaped cavity, the separation cylinder can be inserted into the circular cavity or the U-shaped cavity through the first limiting ring groove or the second limiting ring groove to perform solid-liquid separation or rinsing operations.
[0016] Furthermore, the bottom of the box is connected to a drain pipe on the side of the waterproof seat, and both the drain pipe and the outer end of the compressed air inlet pipe are connected to a solenoid valve.
[0017] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the drain pipe, the compressed air inlet pipe and the solenoid valve, the drain pipe is used to discharge the liquid after solid-liquid separation, the solenoid valve connected to one end of the drain pipe can control the opening and closing of the drain pipe, which facilitates the processing and collection of the separated liquid, and the solenoid valve at one end of the compressed air inlet pipe can control the opening and closing of the compressed air inlet pipe, which facilitates the compressed air to enter the connecting seat, the circular connecting plate and the flushing head through the compressed air inlet pipe, thereby performing the flushing operation on the separation cylinder.
[0018] Furthermore, a lid is hinged to one side of the upper end of the box, a door is hinged to the back of the box at the U-shaped cavity, and support legs are connected to the four outer corners of the box.
[0019] The beneficial effects of adopting the above-mentioned further solution are that by setting a box cover, it is convenient to pour sewage into the separation cylinder or to take the separation cylinder out of the circular cavity and place it in the U-shaped cavity. By setting a box door, it is convenient to maintain and repair the flushing components in the U-shaped cavity, and at the same time, it is convenient to clean the solid impurities that fall into the partition and the circular connecting plate in the separation cylinder after flushing.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This water pollution control solid-liquid separation device first pours wastewater into the separation cylinder, then closes the lid. At this time, liquid molecules in the wastewater are discharged through micro-filter holes and drained through the drain pipe, while solid molecules such as sludge remain in the separation cylinder. Then, the first servo motor is activated to drive the turntable to rotate. Under the attraction of the waterproof electromagnet and the strong magnet, the separation cylinder rotates, allowing the water remaining in the sludge to be discharged again through the micro-filter holes, thus achieving solid-liquid separation. After the operation is completed, the lid is opened, the separation cylinder is removed from the circular cavity, and the sludge is disposed of. At this time, there may be solid impurities such as sludge remaining in the micro-filter holes. The separation cylinder is then inverted so that the hollow ring plate and the limiting ring plate are located at the end of the separation cylinder where the strong magnet is installed. The separation cylinder is then inserted into the U-shaped... Inside the cavity, the cylinder opening is facing downwards, and the limiting ring plate is located in the second limiting ring groove. Then, the compressed air inlet pipe is connected to the air compressor. The air compressor compresses the air to form a compressed air flow with a certain pressure and velocity. This air flows through the compressed air inlet pipe, the connecting seat, and the circular connecting plate, and is then sprayed out by the flushing head to blow away the impurities remaining in the micro-filter holes. The impurities fall onto the partition plate and the circular connecting plate under the action of gravity. When the second servo motor works, it drives the gear to rotate. The gear meshes with the gear ring, causing the connecting seat to rotate, which in turn causes the circular connecting plate and the flushing head to rotate, achieving all-round flushing of the separation cylinder and improving the flushing efficiency and effect. Because the outer wall of the compressed air inlet pipe is clearance-fitted with the inner wall of the through hole at the bottom of the box, when the connecting seat rotates, the compressed air inlet pipe at the bottom of the connecting seat rotates inside the through hole.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-5This utility model provides a technical solution: a solid-liquid separation device for water pollution control, including a placement component 1, a separation component 2, and a rinsing component 3. The separation component 2 and the rinsing component 3 are respectively disposed on both sides inside the placement component 1. The separation component 2 is used for solid-liquid separation of sewage, and the rinsing component 3 is used for rinsing the separation cylinder 22. The placement component 1 includes a box body 11, and a circular cavity 12 and a U-shaped cavity 13 are respectively opened on both sides inside the box body 11. The rinsing component 3 includes a partition plate 31, the outer wall of which is fixedly connected to the inner wall of the U-shaped cavity 13. The interior of the partition plate 31 is open... A rotating groove is provided, and a circular connecting plate 32 is rotatably connected inside the rotating groove. A flushing head 33 is connected to one side of the top surface of the circular connecting plate 32. A connecting seat 34 is connected to the bottom end of the circular connecting plate 32. A compressed air inlet pipe 35 is connected to the bottom end of the connecting seat 34. The compressed air inlet pipe 35 extends through the housing 11 to the outside at the end away from the connecting seat 34. The outer wall of the compressed air inlet pipe 35 is clearance-fitted with the inner wall of the through hole of the housing 11. The bottom end of the connecting seat 34 is connected to the inner bottom end of the U-shaped cavity 13 through a bearing. A toothed ring 36 is sleeved on the outside of the connecting seat 34. At the bottom of housing 11, near the compressed air inlet pipe 35, a second servo motor 38 is installed. The output end of the second servo motor 38 extends through housing 11 into the interior of the U-shaped cavity 13. The output end of the second servo motor 38 is connected to a gear 37, which meshes with a gear ring 36, connecting the compressed air inlet pipe 35 to an air compressor. The air compressor compresses the air, forming a compressed air flow with a certain pressure and velocity. This compressed air flows through the compressed air inlet pipe 35, the connecting seat 34, and the circular connecting plate 32, and is then sprayed out by the flushing head 33, removing residual air from the micro-filter pores. The remaining impurities are blown away and fall onto the partition plate 31 and the circular connecting plate 32 under the action of gravity. When the second servo motor 38 works, it drives the gear 37 to rotate. The gear 37 meshes with the gear ring 36 to drive the connecting seat 34 to rotate, which in turn causes the circular connecting plate 32 and the flushing head 33 to rotate, thereby achieving all-round flushing of the separation cylinder 22 and improving the flushing efficiency and effect. Since the outer wall of the compressed air inlet pipe 35 is clearance-fitted with the inner wall of the through hole at the bottom of the box 11, when the connecting seat 34 rotates, the compressed air inlet pipe 35 at the bottom of the connecting seat 34 rotates inside the through hole.
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-5The present invention provides the following technical solution: A first limiting ring groove 14 and a second limiting ring groove 15 are respectively provided on both sides of the top surface of the housing 11. The separation component 2 includes a limiting ring plate 21, which is disposed within the first limiting ring groove 14. A hollow ring is rotatably connected inside the limiting ring plate 21. A separation cylinder 22 is slidably disposed inside the hollow ring. Four sliding grooves are provided on the outer wall of the separation cylinder 22. Each of the four sliding grooves has a slider near its upper end. The outer walls of the four sliders are slidably engaged with the inner walls of the four sliding grooves, and the outer walls of the four sliders are fixedly connected to the inner walls of the hollow ring. The separator 22 has several micro-filter holes on its exterior. A circular hole is located inside the bottom of the separator 22, and a strong magnet 23 is installed inside the circular hole. A waterproof seat 24 is connected to the bottom of the circular cavity 12. A turntable 26 is rotatably connected to the top surface of the waterproof seat 24. A groove is located on the top surface of the turntable 26, and a waterproof electromagnet 27 is connected inside the groove. The waterproof electromagnet 27 and the strong magnet 23 are magnetically attracted to each other. A first servo motor 25 is installed at the bottom of the waterproof seat 24. The output end of the first servo motor 25 passes through the waterproof seat 24 and is fixed to the bottom of the turntable 26. The separation cylinder 22 is connected via the cooperation of the limiting ring plate 21, the first limiting ring groove 14, the second limiting ring groove 15, the hollow ring plate, and the separation cylinder 22. The cylinder opening faces upwards, and the limiting ring plate 21 is located inside the first limiting ring groove 14. As the separation cylinder 22 rotates within the hollow ring plate, the micro-filter holes on the separation cylinder 22 achieve solid-liquid separation. Through the cooperation of the sliding groove and the slider, after solid-liquid separation is completed, the user removes the separation cylinder 22 and inverts it so that the hollow ring plate and the limiting ring plate 21 are positioned within the separation cylinder 22. With one end equipped with a strong magnet 23, the separation cylinder 22 is inserted into the U-shaped cavity 13 with the cylinder opening facing downwards and the limiting ring plate 21 located in the second limiting ring groove 15. Through the combined use of the first servo motor 25, the turntable 26, the waterproof electromagnet 27, and the strong magnet 23, the waterproof electromagnet 27 is energized, causing it to attract the strong magnet 23. Then, when the first servo motor 25 is working, it drives the turntable 26 to rotate. Under the attraction of the waterproof electromagnet 27 and the strong magnet 23, the separation cylinder 22 rotates, realizing the solid-liquid separation of sewage in the separation cylinder 22.
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-5The present invention provides the following technical solution: The limiting ring plate 21 is composed of a ring plate and four limiting strips on the outer wall of the ring plate. The inner walls of the first limiting ring groove 14 and the second limiting ring groove 15 are respectively clearance-fitted with the outer wall of the limiting ring plate 21. The first limiting ring groove 14 is connected to the circular cavity 12, and the second limiting ring groove 15 is connected to the U-shaped cavity 13. The bottom of the inner part of the box body 11 is connected to a drain pipe 16 on one side of the waterproof seat 24. The drain pipe 16 and the outer end of the compressed air inlet pipe 35 are both connected to a solenoid valve. A box cover 17 is hinged to one side of the upper part of the box body 11. A box door 18 is hinged to the back of the box body 11 at the U-shaped cavity 13. Support legs are connected to the four corners of the outer part of the box body 11. The limiting ring plate 21 is composed of a ring plate and four limiting strips, and the outer wall of the limiting ring plate 21 is clearance-fitted with the first limiting ring groove 14 and the second limiting ring groove 15. The separation cylinder 22 is stably placed. Since the first limiting annular groove 14 is connected to the circular cavity 12 and the second limiting annular groove 15 is connected to the U-shaped cavity 13, the separation cylinder 22 can be inserted into the circular cavity 12 or the U-shaped cavity 13 through the first limiting annular groove 14 or the second limiting annular groove 15 to perform solid-liquid separation or rinsing operations. Through the cooperation of the drain pipe 16, the compressed air inlet pipe 35 and the solenoid valve, the drain pipe 16 is used to discharge the liquid after solid-liquid separation. The solenoid valve connected to one end of the drain pipe 16 can control the opening and closing of the drain pipe 16, which is convenient for processing and collecting the separated liquid. The solenoid valve at one end of the compressed air inlet pipe 35 can control the opening and closing of the compressed air inlet pipe 35, which is convenient for compressed air to enter the connecting seat 34, the circular connecting plate 32 and the rinsing head 33 through the compressed air inlet pipe 35, thereby performing a rinsing operation on the separation cylinder 22.
[0033] Specifically, the working principle of this water pollution control solid-liquid separation device is as follows: First, wastewater is poured into the separation cylinder 22, then the cover 17 is closed. At this time, liquid molecules in the wastewater pass through micro-filter holes and are discharged through the drain pipe 16, while solid molecules such as sludge remain inside the separation cylinder 22. Then, the first servo motor 25 is activated to drive the turntable 26 to rotate. Under the attraction of the waterproof electromagnet 27 and the strong magnet 23, the separation cylinder 22 rotates, allowing the water remaining in the sludge to pass through the micro-filter holes. The filter holes discharge again, achieving solid-liquid separation. After the operation is complete, open the box cover 17, remove the separation cylinder 22 from the circular cavity 12, and dispose of the sludge. At this time, there may be sludge or other solid impurities remaining in the micro-filter holes. Invert the separation cylinder 22 so that the hollow ring plate and the limiting ring plate 21 are located at the end of the separation cylinder 22 where the strong magnet 23 is installed. Insert the separation cylinder 22 into the U-shaped cavity 13, with the cylinder opening facing down and the limiting ring plate 21 located in the second limiting ring groove 15. Then, connect the compressed air inlet pipe 35 to the... The air compressor is connected, and when it works, it compresses the air to form a compressed air flow with a certain pressure and velocity. This compressed air flows through the compressed air inlet pipe 35, the connecting seat 34, and the circular connecting plate 32, and is then sprayed out by the flushing head 33, blowing away the impurities remaining in the micro-filter pores. The impurities fall onto the partition plate 31 and the circular connecting plate 32 under the action of gravity. When the second servo motor 38 works, it drives the gear 37 to rotate. The gear 37 meshes with the gear ring 36, which drives the connecting seat 34 to rotate, thereby causing the circular connecting plate 32 and the flushing head 33 to rotate, achieving all-round flushing of the separation cylinder 22, improving the flushing efficiency and effect. Since the outer wall of the compressed air inlet pipe 35 is clearance-fitted with the inner wall of the through hole at the bottom of the housing 11, when the connecting seat 34 rotates, the compressed air inlet pipe 35 at the bottom of the connecting seat 34 rotates inside the through hole. Opening it facilitates the maintenance and repair of the flushing component 3 in the U-shaped cavity 13, and also facilitates the cleaning of solid impurities that have fallen onto the partition plate 31 and the circular connecting plate 32 in the separation cylinder 22 after flushing.
