Description

Technical Field

[0001] This utility model relates to the field of magnetic filter technology, specifically a leak-proof pipeline magnetic filter. Background Technology

[0002] The working principle of a magnetic filter is based on magnetic force. When a liquid or slurry containing magnetic impurities passes through the filter, the magnetic impurities are attracted by the magnetic rods and firmly adsorbed onto the rods. As the liquid flows, non-magnetic substances continue to pass through the filter, while the magnetic impurities are trapped inside the filter, thus achieving the separation of magnetic impurities from non-magnetic substances. Magnetic filters usually adopt a pipeline structure with flange connections at both ends, which facilitates connection and disassembly with the production line's conveying pipelines.

[0003] A typical pipeline magnetic filter includes a filter body, an inlet pipe, an outlet pipe, a filter cartridge, a magnetic rod, and a cover. The magnetic rod is mounted on the cover, and when the cover is connected to the filter body, the magnetic rod is embedded inside the filter cartridge, thereby intercepting magnetic impurities in the fluid. Generally, the cover and the filter body are only fixed together by bolts, which is not tight and secure enough. This may result in poor sealing, leading to liquid leakage inside the filter, or allowing external impurities or contaminants to enter the filter, affecting the filtration effect.

[0025] like Figure 1-5As shown, in this embodiment,

[0026] A leak-proof pipeline magnetic filter includes a filter body 1, a cover 5, a magnetic rod 6, and a filter cartridge 10. The bottom left end of the filter body 1 is connected to an inlet pipe 2, and the upper right end of the filter body 1 is connected to an outlet pipe 8. The ends of the inlet pipe 2 and the outlet pipe 8 that are close to the filter body 1 are connected to the filter body 1, and the ends of the inlet pipe 2 and the outlet pipe 8 that are away from the filter body 1 are both provided with a connecting flange 3. The edges of the connecting flange 3 are evenly distributed with mounting holes 15.

[0027] The filter body 1 is fixedly connected to the pipeline via the connecting flange 3 on the inlet pipe 2 and the outlet pipe 8, forming a pipeline structure, which facilitates connection and disassembly with the production line conveying pipeline.

[0028] An annular groove 16 is provided on one side of the connecting flange 3. A sealing ring 17 is embedded inside the annular groove 16. The sealing ring 17 is made of fluororubber, which helps to increase the tightness of the filter body 1 after it is connected to the pipeline. At the same time, fluororubber has a certain high temperature resistance.

[0029] A filter cartridge 10 is provided at the center of the filter body 1, and a cover 5 is provided at the top of the filter body 1. Magnetic rods 6 are evenly distributed at the center of the bottom of the cover 5. Several partitions 22 are arranged longitudinally inside the filter body 1. Several partitions 22 are located between the inlet pipe 2 and the outlet pipe 8. A through hole 23 is provided at the center of the partition 22. A sealing ring 24 is provided between the inner wall of the through hole 23 and the filter cartridge 10.

[0030] The magnetic rods 6 all extend into the interior of the filter cartridge 10. When the liquid containing magnetic impurities enters the filter cartridge 10 inside the filter body 1 through the water inlet pipe 2, the magnetic impurities are attracted by the magnetic rods 6 and firmly adsorbed onto the magnetic rods 6.

[0031] The outer side of the magnetic rod 6 is uniformly provided with grooves 21, which can increase the surface area of ​​the magnetic rod 6 in contact with the magnetic material. A larger contact area means that more magnetic material can be adsorbed, thereby improving the adsorption effect.

[0032] A sealing gasket 7 is provided at the connection between the cover 5 and the filter body 1 to increase the tightness of the connection and prevent leakage. The four corners between the cover 5 and the filter body 1 are fixedly connected by fixing bolts 4. Both ends of the fixing bolts 4 are locked by fastening nuts 14, which facilitates the disassembly and cleaning of the magnetic rod 6.

[0033] The end of the fastening nut 14 near the cover 5 and the filter body 1 is tightly fitted to the cover 5 and the filter body 1 through the buffer pad 11. The end of the buffer pad 11 near the fastening nut 14 is provided with a bulge 12, and an elastic strip 13 is provided between the bulge 12 and the fastening nut 14.

[0034] The elastic strips 13 are all made of arched rubber strips, and both ends of the elastic strips 13 abut against the bulge 12. When subjected to external force, they can disperse and buffer the external force through their own elastic characteristics, making it difficult for the fastening nut 14 to loosen, maintaining the sealing effect of the sealing gasket 7, making it difficult for the liquid inside the filter body 1 to leak, and at the same time, it is not easy for external impurities or contaminants to enter the filter body 1, thus avoiding affecting the filtration effect.

[0035] A fixed base 9 is provided at the bottom of the filter body 1, and sliding grooves 18 are provided on both sides of the fixed base 9. A slider 20 matching the sliding groove 18 is provided on the outer side of the bottom of the filter cartridge 10.

[0036] Each of the fixed seats 9 at one end of the slide groove 18 is provided with an insertion port 19, and the slider 20 is inserted into the fixed seat 9 through the insertion port 19 respectively;

[0037] By rotating the filter cartridge 10, the slider 20 at the bottom of the filter cartridge 10 can be rotated to the insertion port 19 at one end of the slide groove 18. Then, by pulling the filter cartridge 10 upward, it can be separated from the fixing seat 9 at the bottom of the filter body 1, which facilitates the disassembly, cleaning or replacement of the filter cartridge 10.

[0038] The working principle and beneficial effects of the above technical solution are as follows:

[0039] In use, the filter body 1 is fixedly connected to the pipeline via the connecting flanges 3 on the inlet pipe 2 and the outlet pipe 8. Each side of the connecting flange 3 has an annular groove 16, into which a sealing ring 17 is embedded to increase the tightness of the connection between the filter body 1 and the pipeline. Magnetic rods 6 are evenly distributed at the bottom of the cover 5. A sealing gasket 7 is placed between the cover 5 and the filter body 1 to increase the tightness of the connection and prevent leakage. The cover 5 and the filter body 1 are evenly connected by fixing bolts 4, both ends of which are locked with fastening nuts 14 for easy disassembly and cleaning of the magnetic rods 6. The elastic strip 13 is made of rubber, with both ends abutting against the bulge 12. When subjected to external force, its elasticity disperses and buffers the force, making it difficult for the fastening nuts 14 to loosen, maintaining the sealing effect of the sealing gasket 7, and preventing liquid from entering the filter body 1. It is easy to leak, and external impurities or contaminants are not easy to enter the filter body 1, so as to avoid affecting the filtration effect. When liquid containing magnetic impurities enters the filter cartridge 10 inside the filter body 1 through the inlet pipe 2, the magnetic impurities are attracted by the magnetic rod 6 and firmly adsorbed on the magnetic rod 6. The outer side of the magnetic rod 6 has grooves 21 evenly distributed, which can increase the surface area of ​​contact between the magnetic rod 6 and the magnetic material. The larger contact area means that more magnetic material can be adsorbed, thereby improving the adsorption effect. As the liquid flows, non-magnetic material continues to flow through the filter cartridge 10 to the outlet pipe 8, while magnetic impurities are trapped inside the filter cartridge 10. In addition, by rotating the filter cartridge 10, the slider 20 at the bottom of the filter cartridge 10 can be rotated to the insertion port 19 at one end of the slide groove 18. Then, the filter cartridge 10 can be pulled upward to separate it from the fixing seat 9 at the bottom of the filter body 1, which is convenient for disassembling, cleaning or replacing the filter cartridge 10.

[0040] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
