Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filter equipment, in particular to a magnetic filter with an automatic slag discharge function. Background Art
[0002] Purification of liquid media is a crucial step in industrial production, particularly in industries such as metallurgy, chemicals, and food processing. Effectively removing ferromagnetic impurities from liquids is crucial for ensuring product quality, extending equipment life, and ensuring production safety. Magnetic filters, as efficient and economical separation devices, utilize the attractive force of magnets to separate ferromagnetic materials from liquids and are widely used in these areas.
[0003] Deficiencies of existing technology:
[0004] Currently, the most common magnetic filters are mainly composed of a shell and several magnetic strips. When the liquid passes through the filter, the mixed ferromagnetic debris will be adsorbed by the magnetic strips. However, during the application of this common magnetic filter, once the ferromagnetic debris adsorbed on the outside of the magnetic strips reaches saturation, the filtering effect will drop significantly. At this time, the magnetic strips need to be cleaned. Conventional cleaning methods require stopping the filtration first, then opening the magnetic filter, removing all the magnetic rods, cleaning all the debris on the surface, and finally putting them back into the filter. Since the entire process requires opening the filter for cleaning, the operation process is complicated and slow, which will undoubtedly have a greater impact on the filtration progress and efficiency. Frequent disassembly of the equipment will also cause wear and tear, reducing the service life of the equipment. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "several" means two or more, unless otherwise specifically defined. Example
[0032] See also Figure 1-5 As shown, the present invention provides a technical solution for a magnetic filter with automatic slag discharge: a magnetic filter with automatic slag discharge, comprising a filter housing 1, an upper cover 2 mounted on the upper end of the filter housing 1, several magnetic strips 3 mounted on the inner side of the upper cover 2, a slag discharge assembly 4 mounted on the lower end of the filter housing 1, and a drive assembly 5 mounted on the upper end of the filter housing 1. The slag discharge assembly 4 includes a cleaning plate 401, a bottom cover 402, a mounting hole 404, and a through hole 406. The cleaning plate 401 is slidably and sealedly connected to the magnetic strips 3 via a sliding hole. The outer side of the cleaning plate 401 is slidably and sealedly connected to the inner sidewall of the filter housing 1. Sealing rings or rubber strips can be provided on the inner and outer walls of the sliding hole of the cleaning plate 401 to ensure a sealing effect without affecting the sliding movement, thereby reducing liquid leakage that may occur during the slag discharge process. The bottom cover 402 is mounted on the lower end of the filter housing 1. Several limit rods 403 are mounted on the outer side of the upper end surface of the bottom cover 402, and a pull ring 4021 is mounted on the lower end of the bottom cover 402. Mounting hole 404 is defined at the lower end of filter housing 1. A limiting rod 403 is slidably connected to the wall of mounting hole 404. A tension spring 405 is located within mounting hole 404, the lower end of which is connected to limiting rod 403. A through hole 406 is defined through cleaning plate 401. Several sealing rods 407, each matching the diameter of through hole 406, are mounted on the upper end surface of bottom cover 402.
[0033] When the filter needs to be drained, the bolts connecting bottom cover 402 to filter housing 1 are removed. Bottom cover 402 maintains a sealed connection to the lower end of filter housing 1 through the tension of tension spring 405 and its built-in sealing ring. The manually controlled drive assembly 5 then moves cleaning plate 401 downward from filter housing 1. As cleaning plate 401 moves downward, debris from the surface of magnetic strip 3 is scraped away. Simultaneously, liquid at the lower end of filter housing 1 flows upward through through-hole 406, ensuring hydraulic balance between the upper and lower ends of filter housing 1. When cleaning plate 401 reaches the lower end of filter housing 1, through-hole 406 on cleaning plate 401 is inserted into sealing rod 407, sealing through-hole 406. Cleaning plate 401 continues to move downward until it and bottom cover 402 overcome the tension of tension spring 405 and separate from the lower end of filter housing 1. At this point, debris from magnetic strip 3 has been pushed out of filter housing 1 and can be cleaned. If the cleaning plate 401 and the bottom cover 402 remain in contact and the debris is difficult to discharge, the pull ring 4021 can be manually pulled to separate the bottom cover 402 from the cleaning plate 401, and then the debris between the two can be cleaned. Note that the sealing rod 407 cannot be completely separated from the through hole 406 to prevent the liquid above the cleaning plate 401 from leaking in large quantities through the through hole 406. After cleaning is completed, the cleaning plate 401 can be reset by the driving component 5. The bottom cover 402 remains in contact with the lower end face of the filter housing 1 under the tension of the tension spring 405. The staff can re-fix the bottom cover 402 to the lower end of the filter housing 1 through bolts. The slag discharge component 4 is used to quickly discharge the debris on the filter magnetic strip 3. The entire process is easy to operate, takes a short time, and does not require the equipment to be disassembled. This significantly improves the cleaning efficiency of the filter, avoids the impact of the filtration progress, reduces the frequency of disassembly of the equipment, and increases the service life of the equipment.
[0034] The drive assembly 5 includes a seal 501 and a mounting bracket 503. The seal 501 is mounted on the cover body of the upper cover 2. The inner side of the seal 501 is slidably sealed and connected to a lifting rod 502. The lower end of the lifting rod 502 passes through the upper cover 2 and is connected to the upper end surface of the cleaning plate 401. The surface of the lifting rod 502 matches the sealing layer of the seal 501 to prevent leakage of the filter. The mounting bracket 503 is mounted on the upper end surface of the upper cover 2. A ball screw 504 is installed on the mounting bracket 503, and the lower end of the ball screw 504 is connected to the upper end of the lifting rod 502. When it is necessary to drive the cleaning plate 401 to rise or fall, the ball screw 504 is rotated, and the ball screw 504 drives the cleaning plate 401 to rise or fall through the lifting rod 502. Through the drive assembly 5, the lifting and lowering of the cleaning plate 401 can be controlled from the outside of the filter housing 1, further improving the convenience of operation and ensuring the efficiency of cleaning.
[0035] The upper cover 2 and the bottom cover 402 are both connected to the filter housing 1 by bolts. The bolt connection has good stability and is more convenient for subsequent replacement and maintenance.
[0036] A limit piece 5021 is installed at the upper end of the lifting rod 502. The length of the lifting rod 502 at the lower end of the limit piece 5021 limits the stroke of the cleaning plate 401 to prevent the cleaning plate 401 from moving downward excessively and falling off from the magnetic strip 3.
[0037] A rotating handle 5041 is installed at the upper end of the ball screw 504 , and the rotating handle 5041 facilitates the staff to operate the rotation of the ball screw 504 .
[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
