[0002] A high-intensity magnetic filter is a filtration device that uses a high-intensity magnetic field to remove magnetic impurities from fluids. It is mainly used in the field of industrial fluid purification.
[0003] Currently, most methods involve filtering magnetic impurities from fluids using strong magnetic filters. Existing strong magnetic filters include a top cover and a cylinder. Magnetic rods for adsorbing magnetic impurities are mounted on the top cover, and the top cover and cylinder are usually connected by bolts. After the magnetic rods adsorb a certain amount of magnetic impurities, the magnetic impurities accumulate on their outer surface, reducing the adsorption capacity. Therefore, it is necessary to clean the magnetic impurities from the magnetic rods periodically, requiring regular disassembly and reassembly of the top cover. Disassembly and reassembly of the top cover requires frequent and repeated rotation of the bolts connecting the top cover and the cylinder, making the operation cumbersome, time-consuming, and inefficient. Therefore, this application proposes a strong magnetic filter. Utility Model Content
[0004] The purpose of this utility model is to provide a strong magnetic filter to solve the problem mentioned in the background art that when periodically cleaning magnetic impurities on the magnetic rod, it is necessary to frequently and repeatedly rotate the bolts at the connection between the top cover and the cylinder, which is cumbersome and inconvenient to disassemble and assemble.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a strong magnetic filter, comprising a cylinder, an inlet / outlet pipe, a top cover, and a magnetic rod. The inlet / outlet pipe is installed on the cylinder and is connected to the cylinder. Fluid enters the cylinder through the inlet / outlet pipe and flows out of the cylinder.

[0018] Beneficial effects:
[0019] This utility model provides a strong magnetic filter. The magnetic rod in the top cover is inserted into the cylinder, ensuring the positioning frame and inner positioning block are aligned with the lugs on the cylinder. After the top cover is fully pressed onto the cylinder, the positioning frame and inner positioning block are inserted into the lugs. Then, the positioning rod is inserted into the positioning frame and lugs from a direction perpendicular to the direction of movement of the positioning frame. The locking groove in the positioning rod is then aligned with the locking block, and the locking block is inserted into the positioning rod. At this point, the positioning rod cannot move left or right relative to each other due to the restriction of the locking block and locking box. The only movement tendency of the positioning rod is restricted, and its position is fixed. Multiple positioning rods lock the positions of multiple lugs and positioning frames, completing the assembly of the top cover and cylinder. This assembly method requires fewer steps for disassembly and assembly, making it easier to clean magnetic impurities adsorbed on the magnetic rod. Compared to rotating bolts, directly pulling the positioning rod is easier and takes less time. Attached Figure Description

The six magnetic rods 16 surround the central magnetic rod and together form an adsorption area to adsorb magnetic core impurities in the fluid. A flange is provided at the inlet and outlet pipes 2, and the inlet and outlet pipes 2 are connected to an external pipe through the flange. The filter's design pressure is 1.0 MPa, the design temperature is 80°C, and the inlet and outlet diameter (i.e., the diameter of the inlet and outlet pipes 2) is DN80 (national standard). The flange is made of PTFE-coated material. The diameter / thickness of the cylinder 1 is: Magnetic rod 16 specifications: magnetic.
[0029] It should be noted that the top cover 3 is provided with an observation window 4, and a sealing plug 5 is inserted into the observation window 4. The outer ring of the sealing plug 5 is provided with a sealing groove, and an O-ring for sealing is provided in the sealing groove.
[0030] Specifically, a drain pipe 6 is provided at the bottom of the cylinder 1, a plunger 7 is inserted into the drain pipe 6, a sealing ring is provided on the plunger 7 for sealing, a pin 8 is inserted into the drain pipe 6, a connecting hole is provided in the plunger 7 to cooperate with the pin 8, and a rubber sleeve is provided at the pin 8 for sealing the connection with the drain pipe 6.
[0031] In order to achieve the assembly between the cylinder 1 and the top cover 3, multiple sets of ear seats 9 are provided on the cylinder 1. Each set of ear seats 9 includes two ear plates. Two positioning frames 10 are provided on the top cover 3. One side of the positioning frame 10 is aligned vertically with the side plate of the ear plate. The positioning frame 10 can be inserted into the ear plate by moving downward. The two positioning frames 10 cooperate with the two ear plates respectively.
[0032] It should be noted that the upper cover 3 is provided with several sets of inner positioning blocks 11. The inner positioning blocks 11 are located between the two positioning frames 10. The two sides of the inner positioning blocks 11 are aligned with the two opposite sides of the two ear plates. When the upper cover 3 is placed on the cylinder 1, the inner positioning blocks 11 are inserted between the two ear plates, and the two sides of the inner positioning blocks 11 are in contact with the two opposite sides of the two ear plates.

After the top cover 3 is completely pressed on the cylinder 1, the positioning frame 10 and the inner positioning block 11 are inserted into the ear seat 9. Then, the positioning rod 12 is inserted into the positioning frame 10 and the ear seat 9 from a direction perpendicular to the moving direction of the positioning frame 10. Then, the locking groove in the positioning rod 12 is aligned with the locking block 13 and the locking block 13 is inserted into the positioning rod 12. At this time, the positioning rod 12 cannot move left or right relative to each other under the restriction of the locking block 13 and the locking box 14. The only movement trend of the positioning rod 12 is restricted. At this time, the position of the positioning rod 12 is fixed.

[0036] In summary, this utility model embodiment provides a strong magnetic filter. The magnetic rod 16 in the upper cover 3 is inserted into the cylinder 1, and care is taken to align the positioning frame 10, the inner positioning block 11 with the ear seat 9 on the cylinder 1. After the upper cover 3 is completely pressed onto the cylinder 1, the positioning frame 10 and the inner positioning block 11 are inserted into the ear seat 9. Then, the positioning rod 12 is inserted into the positioning frame 10 and the ear seat 9 from a direction perpendicular to the moving direction of the positioning frame 10. Then, the locking groove in the positioning rod 12 is aligned with the locking block 13, and the locking block 13 is inserted into the positioning rod 12. At this time, the positioning rod 12 cannot move left or right relative to each other under the restriction of the locking block 13 and the locking box 14. The only movement trend of the positioning rod 12 is restricted. At this time, the position of the positioning rod 12 is fixed. Multiple positioning rods 12 lock the positions of multiple ear seats 9 and positioning frames 10, completing the assembly work between the upper cover 3 and the cylinder 1. The assembly of the upper cover 3 and the cylinder 1 in this way requires fewer steps for disassembly and assembly, and is more convenient to disassemble and assemble, making it easier to clean the magnetic impurities adsorbed on the magnetic rod 16.
