[0029] Example 1

[0030] This embodiment provides a novel magnetic filter, as shown in the attached image. Figure 1 and attached Figure 3 As shown, the system includes a housing 1, a filter basket 2, a flange cover 3, and a magnetic suction assembly. The assembly structure of the housing, filter basket, and flange cover is that of an existing basket filter, and will not be described in detail here. The magnetic suction assembly is fixedly disposed inside the filter basket and fixedly mounted on the flange cover. The magnetic suction assembly includes a fixing base 4, multiple strong magnetic columns 5, multiple connecting columns 6, a rubber plate 7, a drive rod 8, and a strong magnetic block 9, wherein:

[0031] The top sleeve 4.1 of the fixing seat 4 passes through the flange cover 3 and is fixed with a nut. The bottom of the fixing seat 4 is provided with multiple blind holes 4.2 for inserting the strong magnetic column 5. In this embodiment, the fixing seat 4 is preferably made of non-magnetic material, and a sealing element (not shown in the figure) is provided between the fixing seat 4 and the flange cover 3 for sealing.

[0032] The top of the drive rod 8 passes through the sleeve 4.1 of the fixed base 4 in a movable and sealed manner, and its bottom extends to the bottom of the filter basket 2, where a strong magnetic block 9 is fixedly installed. The drive rod 8 also has a spiral groove 8.1. In this embodiment, the drive rod 8 and the sleeve 4.1 of the fixed base 4 are movably connected. Rotary seals are provided at both ends of the sleeve 4.1 to ensure a seal during rotation of the drive rod 8. The strong magnetic block 9 is preferably installed by fixing it to the threaded joint of the drive rod 8 with a nut, allowing for easy installation and removal.

[0033] A plurality of strong magnetic columns 5 are arranged between the fixed seat 4 and the strong magnetic block 9, and one end of each strong magnetic column 5 is fixed in the blind hole 4.2, and the other end is fixed to the connecting column 6 made of non-magnetic material with the same outer diameter. Preferably, the blind hole 4.2 and the strong magnetic column 5 are in interference fit, and the blind hole 4.2 is coated with strong glue. During assembly, first coat the blind hole with strong glue, then insert the strong magnetic column into the blind hole, and after the glue is cured, the assembly is completed. Similarly, the top of the connecting column 6 is provided with a socket, the bottom of the strong magnetic column 5 is provided with a plug-in connector, the plug-in connector and the socket are in interference fit, and the socket is coated with strong glue. The strong magnetic column fixing and mounting mode of the embodiment is reliable in structure.

[0034] The rubber plate 7 is movably arranged on the driving rod 8, the inner wall of the rubber plate 7 is provided with a protrusion 7.1 embedded in the spiral groove 8.1, and the rubber plate 7 is provided with a through hole 7.2 corresponding to each strong magnetic column 5. When the driving rod rotates, the spiral groove on the driving rod drives the protrusion on the rubber plate to move, thereby driving the rubber plate to move along the length direction of the driving rod.

[0035] Preferably, the bottom of the connecting column 6 of the embodiment is further provided with a limiting plate 6.1 for limiting the rubber plate to prevent the rubber plate from completely coming out of the connecting column.

[0036] Preferably, the top of the driving rod 8 of the embodiment is provided with a handle 8.2 or a transmission mechanism for controlling the forward or reverse rotation of the driving rod. When the handle is set, the driving rod is controlled to rotate by manpower; when the transmission mechanism is set, the driving rod can be driven by the driving device through the transmission mechanism.

[0037] In specific use, the initial position of the scraper is located at the top of the strong magnetic column. With the operation of the filter, after the strong magnetic column adsorbs a certain amount of iron filings, the rubber plate can be lowered by controlling the rotation of the driving rod. Under the action of the rubber plate, the iron filings adsorbed on the strong magnetic column move downward along the strong magnetic column until the rubber plate moves to the connecting column. Since the connecting column has no magnetic attraction, the iron filings are separated from the connecting column and are adsorbed by the strong magnetic block below. When the rubber plate moves to the limiting plate, the driving rod is turned over to move the scraper to the uppermost position.

[0038] After a certain period of time, the magnetic assembly needs to be disassembled for cleaning. During cleaning, the flange cover plate is removed, the strong magnetic column is cleaned according to the above method, then the nut is loosened, the strong magnetic block is removed for cleaning, and after cleaning, the strong magnetic block is installed, and the flange cover plate is installed on the shell.

[0039] Embodiment two

[0040] On the basis of embodiment one, the structure of the embodiment is further optimized and designed, as shown in Figs. 2 and 3. Figure 1 and Figs. 4 and 5. Figure 3As shown, the device further comprises a net fence 10, which is detachably wrapped around the outer edge of the strong magnetic block 9, and the height of the net fence 10 exceeds the connecting column 6. The net fence designed in the embodiment can maintain the scraped iron filings in a certain area and be adsorbed by the strong magnetic block.

[0041] The above is only the embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation made by using the content of the present application specification, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
