Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a self-cleaning fluid filtration device. Background Technology

[0002] A fluid filtration device is a device used to separate and remove impurities, particles, suspended solids, and other contaminants from fluids. It uses physical, chemical, or mechanical methods to force the fluid through a specific filter medium, trapping solids or other insoluble substances, thereby purifying the fluid. Using a fluid filtration device can reduce or prevent damage to valves and other equipment caused by impurities, thus ensuring their normal operation. A fluid filtration device generally consists of a housing and a filter cartridge housed within the housing. During operation, wastewater enters the housing and the filter cartridge through the inlet, where impurities carried by the wastewater are trapped and filtered.

[0003] Based on the above, the inventors have discovered the following problems: After the current filter cartridges have filtered the impurities in the wastewater, the impurities will accumulate inside the filter cartridges, requiring manual removal of the filter cartridges for cleaning. After cleaning, the filter cartridges must be reinstalled in their original positions, which is quite inconvenient.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a self-cleaning fluid filtration device in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning fluid filtration device 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 self-cleaning fluid filtration device includes a filter assembly, a drive assembly, and a cleaning assembly. The drive assembly is disposed inside the filter assembly, and the cleaning assembly is disposed on the outer side of the filter assembly. The drive assembly drives the filter cartridge to rotate, and the cleaning assembly cleans the filter cartridge. The cleaning assembly includes a connecting seat, which is hollow inside. A plurality of mounting holes are formed on one side of the connecting seat, and each of the mounting holes has an air nozzle installed inside. The inner diameter of the air nozzle decreases from right to left. A compressed air inlet pipe is connected to the side of the connecting seat opposite to the mounting holes. The filter assembly includes a filter box, which has an elongated groove on its outer side. The outer wall of the filter box with the elongated groove is fixedly connected to one side of the connecting seat. The ends of the air nozzles away from the connecting seat are all located inside the elongated groove, and the ends of the air nozzles away from the connecting seat are all flush with the inner wall of the elongated groove in the filter box.

[0008] Furthermore, grooves are provided on both sides of the interior of the filter box, and linear motors are installed inside the two grooves. The moving ends of the two linear motors are respectively equipped with a first hollow cylinder and a second hollow cylinder. The opposite sides of the first hollow cylinder and the second hollow cylinder are respectively rotatably connected to a first connecting seat and a second connecting seat. A hollow ring is installed between the first connecting seat and the second connecting seat. A filter cylinder is rotatably connected inside the hollow ring. A magnetic ring is fitted on the outside of the filter cylinder near the bottom end.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by setting two linear motors of the same model and with the same moving speed at the moving ends of the two linear motors, when the two linear motors are working, the first hollow cylinder and the second hollow cylinder move synchronously. When the first hollow cylinder and the second hollow cylinder move to the right synchronously, the filter cylinder is misaligned with the drain pipe. When it moves to the middle of the linear motor, the micro servo motor of the first hollow cylinder is activated, so that the filter cylinder begins to slowly flip as it moves to the right and approaches the cleaning component. When the filter cylinder moves to the rightmost end of the linear motor, the filter cylinder has completely flipped over with the cylinder opening facing down and the magnetic ring on top.

[0010] Furthermore, a micro servo motor is installed inside the first hollow cylinder, and the output end of the micro servo motor is fixedly connected to the first connecting seat.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting a micro servo motor, when the micro servo motor is working, it is easy to drive the first connecting seat to rotate. Since a hollow ring is installed between the first connecting seat and the second connecting seat, and the second connecting seat is rotatably connected to the second hollow cylinder, the filter cartridge can be flipped.

[0012] Furthermore, a cover is hinged to one side of the upper end of the filter box, and the bottom end of the cover fits against the upper end of the filter box. The drive assembly includes an electric turntable, which is located on one side of the bottom end of the cover. An electromagnet is installed at the bottom end of the electric turntable. When the electromagnet is energized, it can magnetically attract a magnetic ring. An electric telescopic rod is installed at the center of the electric turntable at the upper end of the cover. The movable end of the electric telescopic rod passes through the cover and is fixedly connected to the upper end of the electric turntable.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting an electric telescopic rod, when the electric telescopic rod is working, it is convenient to realize the upward or downward movement of the electric turntable. When the electric turntable moves downward and the filter cartridge moves to the rightmost end of the linear motor, at this time the filter cartridge has been completely flipped over and the cylinder opening is facing down with the magnetic ring on top. When this happens, the electromagnet is energized, causing the electromagnet to attract the magnetic ring. Then the electric turntable works to drive the filter cartridge to rotate inside the hollow ring, so that the cleaning component can perform all-round air blowing cleaning on the surface of the filter cartridge.

[0014] Furthermore, the top of the cover is connected to a water inlet pipe at a point away from the electric telescopic rod, a partition is installed at the center of the bottom of the filter box, and a drain pipe is connected to the bottom of the filter box on one side of the partition. The centers of the drain pipe, the filter cylinder, and the drain pipe are located on the same axis, and one end of the water inlet pipe, the drain pipe, and the compressed air inlet pipe is connected to a flange.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, by aligning the centers of the drain pipe, filter cartridge, and drain pipe on the same axis, the fluid flows into the filter cartridge through the inlet pipe, is filtered by the filter cartridge, and then discharged through the drain pipe. By setting a baffle, the water discharged from the filter cartridge will not be discharged from the drain outlet. Flanges are connected to one end of the inlet pipe, drain pipe, and compressed air inlet pipe, so that the inlet pipe and outlet pipe are connected to external pipelines through the flanges, and the compressed air inlet pipe is connected to the exhaust port of the air compressor.

[0016] Furthermore, the bottom of the filter box has a drain outlet on the side away from the drain pipe, and the drain outlet and the drain pipe are located on both sides of the partition.

[0017] The advantage of adopting the above-mentioned further solution is that by setting up a drain outlet, it is convenient for filtered impurities after cleaning to be discharged from the drain outlet.

[0018] Furthermore, the filter cartridge is made of stainless steel filter mesh.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by setting the filter cartridge to a stainless steel filter screen material, the strength and service life of the filter cartridge are improved.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This self-cleaning fluid filtration device connects the compressed air inlet pipe to the exhaust port of the air compressor. When the two linear motors are started, the first and second hollow cylinders move synchronously to the right, causing the filter cartridge to be misaligned with the drain pipe. When it moves to the middle of the linear motor, the micro servo motor of the first hollow cylinder is started, driving the first connecting seat to rotate. Since a hollow ring is installed between the first and second connecting seats, and the second connecting seat is rotatably connected to the second hollow cylinder, the filter cartridge begins to slowly rotate as it moves to the right and approaches the cleaning component. When the filter cartridge moves to the rightmost end of the linear motor, the filter cartridge has completely rotated and the cylinder opening is facing downwards, with the magnetic ring located at the top. Above, when the electric telescopic rod is activated, the electric turntable moves downward, energizing the electromagnet and causing it to attract the magnetic ring. The electric turntable then rotates the filter cartridge within the hollow ring. Simultaneously, the air compressor activates, allowing compressed air to enter the connecting seat through the compressed air inlet pipe and exit through the air nozzle to clean the filter cartridge surface. This allows the cleaning components to perform comprehensive air cleaning of the filter cartridge surface. The air compressor compresses the air, giving it high pressure and energy. Because the inner diameter of the air nozzle decreases from right to left, the compressed air is ejected from the nozzle at high speed, effectively cleaning the filter screen and removing impurities adhering to it, thus achieving the cleaning purpose.

[0026] 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.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a self-cleaning fluid filtration device, including a filter assembly 1, a drive assembly 2, and a cleaning assembly 3. The drive assembly 2 is disposed inside the filter assembly 1, and the cleaning assembly 3 is disposed on the outer side of the filter assembly 1. The drive assembly 2 is used to drive the filter cartridge 18 to rotate, and the cleaning assembly 3 is used to clean the filter cartridge 18. The cleaning assembly 3 includes a connecting seat 31, which is hollow inside and has several mounting holes on one side. Each mounting hole has an air nozzle 32 installed inside it, with the inner diameter of the air nozzle 32 decreasing from right to left. The connecting seat 31 has a compressed air inlet pipe 33 connected to the side opposite to the mounting holes. The filter assembly 1 includes a filter box 11, which has an elongated groove on one side. The outer wall of the filter box 11 with the elongated groove is fixedly connected to one side of the connecting seat 31. Each air nozzle 32 is located at the end away from the connecting seat 31. Located inside the long slot, several air nozzles 32 are flush with the inner wall of the long slot in the filter box 11 at the end away from the connecting seat 31. The compressed air inlet pipe 33 is connected to the exhaust port of the air compressor. The air compressor is started, so that the compressed air enters the interior of the connecting seat 31 through the compressed air inlet pipe 33 and is then discharged from the air nozzles 32 to blow clean the surface of the filter cartridge 18. This allows the cleaning component 3 to blow clean the surface of the filter cartridge 18 from all directions. The air compressor compresses the air, giving it high pressure and energy. Since the inner diameter of the air nozzles 32 decreases from right to left, the air compressed by the air compressor can be ejected from the air nozzles 32 in the form of a high-speed airflow, effectively blowing away the impurities attached to the filter screen and achieving the purpose of cleaning. The working principle of the air compressor is the content of the air compressor in patent publication number CN211722280U.

[0028] 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.

[0029] Please see Figures 1-4This utility model provides a technical solution: Grooves are provided on both sides of the interior of the filter box 11. Linear motors 14 are installed inside each of the two grooves. A first hollow cylinder 15 and a second hollow cylinder 16 are respectively installed on the moving ends of the two linear motors 14. A first connecting seat and a second connecting seat are rotatably connected to opposite sides of the first hollow cylinder 15 and the second hollow cylinder 16. A hollow ring 17 is installed between the first connecting seat and the second connecting seat. A filter cartridge 18 is rotatably connected inside the hollow ring 17. A magnetic ring 19 is fitted onto the outside of the filter cartridge 18 near its bottom end. A micro servo motor is installed inside the first hollow cylinder 15. The output end of the micro servo motor is fixedly connected to the first connecting seat. A cover 12 is hinged to one side of the upper end of the filter box 11. The bottom end of the cover 12 fits against the upper end of the filter box 11. The drive assembly 2 includes an electric turntable 21, which is located on one side of the bottom end of the cover 12. An electromagnet 22 is installed at the bottom end of the electric turntable 21. When the electromagnet 22 is energized, it can magnetically attract the magnetic ring 19. An electric telescopic rod 2 is installed at the center of the electric turntable 21 on the upper end of the cover 12. 3. The movable end of the electric telescopic rod 23 passes through the box cover 12 and is fixedly connected to the upper end of the electric turntable 21. When the two linear motors 14 are started, the first hollow cylinder 15 and the second hollow cylinder 16 move to the right synchronously, causing the filter cartridge 18 to be misaligned from the drain pipe 111. When it moves to the middle of the linear motor 14, the micro servo motor of the first hollow cylinder 15 is started, driving the first connecting seat to rotate. Since a hollow ring 17 is installed between the first connecting seat and the second connecting seat, and the second connecting seat is rotatably connected to the second hollow cylinder 16, the filter cartridge 18 continuously moves to the right. As the filter cartridge 18 moves to the right and approaches the cleaning component 3, it begins to slowly flip. When the filter cartridge 18 moves to the rightmost end of the linear motor 14, the filter cartridge 18 has completely flipped over with the opening facing down and the magnetic ring 19 positioned above. When the electric telescopic rod 23 is activated, the electric turntable 21 moves downward, and the electromagnet 22 is energized, causing the electromagnet 22 to attract the magnetic ring 19. Then, the electric turntable 21 works to drive the filter cartridge 18 to rotate inside the hollow ring 17. The working principle of the electric turntable 21 is the same as that of the electric turntable 21 in patent publication number CN209687692U.

[0030] 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.

[0031] Please see Figures 1-4This utility model provides a technical solution: A water inlet pipe 13 is connected to the top of the cover 12 at a location away from the electric telescopic rod 23. A partition 110 is installed at the center of the bottom of the filter box 11. A drain pipe 111 is connected to the bottom of the filter box 11 on one side of the partition 110. The centers of the drain pipe 111, the filter cartridge 18, and the drain pipe 111 are located on the same axis. One end of the water inlet pipe 13, the drain pipe 111, and the compressed air inlet pipe 33 are all connected to a flange. A drain outlet 112 is provided at the bottom of the filter box 11 on the side away from the drain pipe 111. The drain outlet 112 and the drain pipe 111 are located on opposite sides of the partition 110. The filter cartridge 18 is made of stainless steel filter mesh. The fluid is filtered through the filter cartridge 18 and the drain pipe 111 is located on the same axis. The fluid flows into the filter cartridge 18 through the inlet pipe 13, is filtered by the filter cartridge 18, and then discharged through the drain pipe 111. By setting the baffle 110, the water discharged from the filter cartridge 18 will not be discharged from the drain port 112. One end of the inlet pipe 13, the drain pipe 111 and the compressed air inlet pipe 33 are all connected to flanges, so that the inlet pipe 13 and the outlet pipe are connected to external pipes through flanges, and the compressed air inlet pipe 33 is connected to the exhaust port of the air compressor. By setting the drain port 112, it is convenient for the filtered impurities after cleaning to be discharged from the drain port 112.

[0032] Specifically, the working principle of this self-cleaning fluid filtration device is as follows: During use, the centers of the drain pipe 111, filter cartridge 18, and drain pipe 111 are aligned on the same axis. Fluid flows into the filter cartridge 18 through the inlet pipe 13, is filtered by the filter cartridge 18, and then discharged through the drain pipe 111. A baffle 110 prevents water discharged from the filter cartridge 18 from the drain port 112. When cleaning is required, the compressed air inlet pipe 33 is connected to the exhaust port of the air compressor. When the two linear motors 14 are started, the first hollow cylinder 15 and the second hollow cylinder 16 move synchronously to the right, causing the filter cartridge 18 to be misaligned with the drain pipe 111. When the filter cartridge 18 reaches the middle of the linear motor 14, the micro servo motor of the first hollow cylinder 15 is activated, driving the first connecting seat to rotate. Because a hollow ring 17 is installed between the first and second connecting seats, and the second connecting seat is rotatably connected to the second hollow cylinder 16, the filter cartridge 18 slowly rotates as it moves to the right towards the cleaning component 3. When the filter cartridge 18 moves to the rightmost end of the linear motor 14, the filter cartridge 18 is completely flipped over with the opening facing down and the magnetic ring 19 is on top. When the electric telescopic rod 23 is activated, the electric turntable 21 moves downward, and the electromagnet 22 is energized, causing the electromagnet 22 to attract the magnetic ring 19. Then, the electric turntable 21 works to drive the filter cartridge 18 to rotate inside the hollow ring 17. The air compressor is activated, so that compressed air enters the interior of the connecting seat 31 through the compressed air inlet pipe 33 and is discharged from the air nozzle 32 to blow clean the surface of the filter cartridge 18. This allows the cleaning component 3 to blow clean the surface of the filter cartridge 18 from all directions. The air compressor compresses the air, giving it high pressure and energy. Since the inner diameter of the air nozzle 32 decreases from right to left, the air compressed by the air compressor can be ejected from the air nozzle 32 in the form of a high-speed airflow, effectively blowing away the impurities attached to the filter screen and achieving the purpose of cleaning. The cleaned filter impurities are discharged from the drain port 112.

[0033] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
