Description

Technical Field

[0001] The invention relates to the technical field of filtering devices, in particular to an anti-clogging electromagnetic filter device. Background Art

[0002] The working principle of the electromagnetic filter is to use electromagnetic force to remove magnetic oxides from water. The electromagnetic filter uses electromagnetic force to adsorb and remove magnetic oxides in water. This filter usually contains strong magnetic materials and blocking filters. When water containing magnetic oxides passes through, the magnetic oxides will be adsorbed on the magnetic material, thereby achieving separation and purification. Electromagnetic filters are suitable for a variety of application scenarios, including but not limited to water treatment, chemical production, etc., and can effectively remove magnetic impurities in water to ensure the purity of water quality or production processes. In addition, the working principle of the magnetic filter is mainly based on magnetic adsorption and fluid dynamics. It contains strong magnetic materials and blocking filters. When a fluid containing ferromagnetic impurities passes through, these impurities will be adsorbed on the magnetic material to achieve separation and purification. Some magnetic filters also use turbulent conditions to change the water flow speed and pressure and release bubbles. The bubbles gather on the metal net, and the impurities are separated from the fluid by gravity.

[0003] A search of Chinese utility model patent publication number CN218742493U discloses an electromagnetic filter for pipelines, which uses an electromagnetic adsorber to adsorb magnetic oxides in water. However, over a long period of use, as the magnetic oxides adsorbed on the surface of the electromagnetic adsorber accumulate, the thickness of the magnetic oxides adsorbed on the surface of the electromagnetic adsorber becomes larger, which affects the adsorption capacity of the electromagnetic adsorber. At the same time, the magnetic oxides are directly attached to the filter screen without being adsorbed by the electromagnetic adsorber, which causes blockage on the filter screen surface. If manual cleaning is relied on, the liquid flow of the entire pipeline needs to be closed during disassembly, causing inconvenience. Therefore, there is a need for an electromagnetic filtering device that can reduce the cleaning cycle of the electromagnetic filter and avoid blockage of the filter screen. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 - Fig. 9The present invention provides a technical solution: an anti-clogging electromagnetic filter device, including a filter chamber 2, an outer wall of the filter chamber 2 is provided with a water inlet 3 and a water outlet 1, the water inlet 3 and the water outlet 1 are respectively connected to the water inlet end and the water outlet end of the pipeline, a mounting port is provided on the periphery of the lower side of the filter chamber 2, a filter tank 5 is inserted on the mounting port, a plurality of filter holes are provided on the periphery of the filter tank 5, the filter tank 5 is open at one end facing the water inlet 3, and the open end of the filter tank 5 is inserted into the filter chamber 2, so that the filter tank 5 can pass through the filter chamber 2. The interior of the filter tank 5 is connected with the water inlet 3, and the liquid in the pipeline enters the filter tank 5 from the water inlet 3. A transition chamber 6 is formed between the outer wall of the filter tank 5 and the inner wall of the filter bin 2. A protrusion 14 is fixedly connected to the filter tank 5. The protrusion 14 is narrow at the top and wide at the bottom, that is, the upper end of the protrusion 14 is a small-diameter end. An electromagnetic absorber 11 is penetrated at the bottom of the filter tank 5. The upper end of the electromagnetic absorber 11 penetrates into the filter tank 5. One end of the electromagnetic absorber 11 that penetrates into the filter tank 5 is hinged with four sealing covers 4 (such as Figure 3 As shown), after the four sealing covers 4 rotate along the hinge axis of the electromagnetic absorber 11, the four sealing covers 4 will be combined into a cylindrical shape, and a cleaning cavity is formed between the inner wall of the sealing cover 4, the outer wall of the protrusion 14 and the outer wall of the electromagnetic absorber 11;

[0035] One end of the electromagnetic absorber 11 that penetrates into the filter tank 5 is sleeved with a scraper ring 18 that can slide freely up and down. The lower end surface of the scraper ring 18 is vertically fixed with two tie rods 9. The two tie rods 9 are symmetrically arranged along the axial direction of the scraper ring 18, and the tie rods 9 pass through the protrusion 14 and the filter tank 5 and slide freely. The lower end of the tie rod 9 is fixed with a floating plate 10. The bottom of the filter tank 5 is vertically installed with a cylinder 7. The cylinder rod of the cylinder 7 is connected to the floating plate 10. The cylinder rod of the cylinder 7 is extended and retracted, so that the cylinder 7 drives the tie rod 9 to move up and down, so that the tie rod 9 drives the scraper ring 18 to move up and down accordingly. The scraper ring 18 moves to scrape the magnetic oxide on the surface of the electromagnetic adsorber 11. When the four sealing covers 4 rotate downward to form a cylindrical structure, the periphery of the scraper ring 18 conflicts with the inner wall of the sealing cover 4, that is, the outer diameter of the scraper ring 18 is consistent with the inner diameter of the cylindrical structure, and the surface gap between adjacent sealing covers 4 is small. An annular storage cavity 17 is provided on the upper end surface of the protrusion 14, and the storage cavity 17 is connected with the cleaning cavity. In this way, when the scraper ring 18 scrapes the magnetic oxide on the surface of the electromagnetic adsorber 11, the magnetic oxide will be driven into the storage cavity 17.

[0036] The inner wall of the filter tank 5 is fixedly connected with a mounting ring 12, and a driving spring 19 is fixedly connected between the inner ring wall of the mounting ring 12 and the outer wall of the sealing cover 4. The driving spring 19 generates an elastic resisting force on the sealing cover 4 in the direction of the electromagnetic absorber 11, and then in the initial state, the driving spring 19 drives the sealing cover 4 to swing downward, so that the sealing cover 4 is combined into a cylindrical structure. In addition, a plurality of resisting columns 13 are fixedly connected to the upper end surface of the scraper ring 18, and the positions and number of the resisting columns 13 are consistent with the positions and numbers of the plurality of sealing covers 4, and then when the scraper ring 18 slides upward on the surface of the electromagnetic absorber 11, the ends of the resisting columns 13 will resist the sealing cover 4, so that the sealing cover 4 has an upward swinging force, and then the sealing cover 4 is swung upward along the hinge axis with the electromagnetic absorber 11, and then the sealing covers 4 are mutually unfolded, so that when the electromagnetic absorber 11 is working, it can adsorb the magnetic oxides in the water in the filter tank 5;

[0037] A packing cavity 20 is coaxially provided in the filter tank 5, and the packing cavity 20 is filled with filter material. A sliding ring 16 is coaxially engaged in the packing cavity 20, and the sliding ring 16 slides up and down in the packing cavity 20. A rotating rod 15 is horizontally penetrated through the inner wall of the filter tank 5, and the rotating rod 15 rotates freely on the inner wall of the filter tank 5. The rotating rod 15 is arranged below the sliding ring 16. The rotating rod 15 (such as Fig. 9 As shown in the figure, one end of the rod 15 that penetrates into the packing cavity 20 is fixedly connected with a protrusion 24, and the end of the rotating rod 15 that faces the protrusion 14 is coaxially fixedly connected with a gear portion 21, and the rotating rod 15 is rotatably arranged on the protrusion 14. The peripheral edge of the pull rod 9 is provided with an escape groove 8 for the gear portion 21 to pass freely, and the inner wall of the escape groove 8 is provided with a rack portion 22 that meshes with the gear portion 21. The lower end surface of the protrusion 14 is provided with a blind hole-shaped accommodating cavity 23, and the gear portion 21 is located in the accommodating cavity 23. When the cylinder rod of the cylinder 7 is extended, the drive The movable floating plate 10 moves downward, thereby driving the pull rod 9 to move downward, and enabling the gear portion 21 to mesh with the rack portion 22, thereby driving the gear portion 21 to drive the rotating rod 15 to rotate, so that the protrusion 24 rotates 90°, and then the protrusion 24 lifts the sliding ring 16, so that the sliding ring 16 compacts the filter filler in the filler cavity 20, so that the gap between the filter filler is reduced. In addition, the surface of the sliding ring 16 is chrome-plated, so that the wear of the lower end face of the sliding ring 16 and the surface of the protrusion 24 when sliding is small.

[0038] The working principle of the present invention is as follows: in the initial state, the cylinder rod of the cylinder 7 is in a shortened state, so that the cylinder 7 drives the floating plate 10 to move upward, and the scraper ring 18 slides on the electromagnetic absorber 11, and the end of the abutting column 13 abuts the sealing cover 4, so that the sealing cover 4 has an upward swinging force, and then the sealing cover 4 swings upward along the hinge axis with the electromagnetic absorber 11, and then the sealing covers 4 are unfolded with each other, so that the water in the filter tank 5 will contact the surface of the electromagnetic absorber 11, and the electromagnetic absorber 11 will generate magnetism when it works, and then the magnetic oxides in the water will be adsorbed, and the water will enter the filling cavity 20 through the filter holes on the surface of the filter tank 5, so that the water is filtered by the filter filler in the filling cavity 20, and the filtered water enters the transition cavity 6, and then enters the external pipeline from the water outlet 1, so as to achieve the filtration of the water;

[0039] When the cleaning cycle of the electromagnetic absorber 11 is reached (technical knowledge of those skilled in the art), the cylinder 7 is started, and the cylinder rod of the cylinder 7 is extended, thereby driving the floating plate 10 to move downward, so that the pull rod 9 drives the scraper ring 18 to move downward, and the abutment state of the abutment column 13 on the sealing cover 4 disappears. At this time, the elastic potential energy of the driving spring 19 is released, so that the sealing cover 4 swings downward along the hinge axis with the electromagnetic absorber 11, and then the sealing cover 4 is combined into a cylindrical structure. At this time, the inner wall of the lower side of the sealing cover 4 is engaged and contacted with the peripheral edge of the small diameter end of the protrusion 14, and a cleaning cavity is formed between the sealing cover 4, the upper end surface of the protrusion 14 and the peripheral edge of the electromagnetic absorber 11, and the scraper ring 18 slides downward on the peripheral edge of the electromagnetic absorber 11. The magnetic oxide attached to the surface of the electromagnetic absorber 11 is scraped off, so that the magnetic oxide is scraped into the storage cavity 17 of the protrusion 14 by the scraper ring 18. When the scraper ring 18 scrapes off the magnetic oxide, the water in the cleaning cavity will overflow from the gap of the sealing cover 4, and the magnetic oxide will remain in the storage cavity 17. The depth of the storage cavity 17 is set to 1-2 mm. In this way, the scraper ring 18 can compact the magnetic oxide in the storage cavity 17, so that the magnetic oxide is pressed into a sheet or cake shape. At this time, the magnetic oxide is transformed from the original powder granular state into a larger solid state, which is not easy to float in the water body. In this way, when the water body continues to be filtered, the magnetic oxide will not cause the filter holes on the filter tank 5 to be blocked;

[0040] In addition, synchronously, when the pull rod 9 moves downward to a fixed position, the gear portion 21 will mesh with the rack portion 22, causing the gear portion 21 to rotate and drive the rotating rod 15 to rotate, so that the rotating rod 15 drives the protrusion 24 to rotate, causing the protrusion 24 to rotate 90°, and then the protrusion 24 lifts the sliding ring 16, so that the sliding ring 16 compacts the filter filler in the filler cavity 20, so that the gap of the filter filler is reduced, so that when the scraper ring 18 compacts the magnetic oxide on the surface of the electromagnetic adsorber 11, the gap of the filter filler is reduced, and the magnetic oxide in the water body is prevented from escaping from the gap of the filter filler, thereby causing the filtering effect of the magnetic oxide in the water body to decrease. The whole process basically does not require manual operation and is relatively convenient. In addition, after performing multiple cleaning operations, the staff disassembles the filter tank 5 for cleaning. Compared with the prior art, the cleaning cycle of the filter tank 5 is reduced, and the frequent closure of the pipeline to affect the liquid transportation is avoided.
