Description

Technical Field

[0001] This application relates to the technical field of iron separators, and in particular to a drawer-type iron separator with a self-cleaning function. Background Technology

[0002] The drawer-type magnetic separator is a device used to remove ferromagnetic impurities from powdery, flaky, and granular raw materials. It is widely used in industries such as ceramics, power, and mining. This device uses magnetic filter rods fixed in a drawer-type frame to adsorb iron-containing substances, effectively protecting production equipment and product safety. Its features include low energy consumption, high efficiency, simple structure, and easy installation. The magnetic rods are arranged in an alternating pattern with a precise magnetic spacing design. Different configurations can be customized to meet specific needs.

[0003] Existing drawer-type iron separators generally require manual cleaning when removing iron impurities, and cannot achieve automated cleaning. Therefore, the applicant has designed a drawer-type iron separator with a self-cleaning function. Utility Model Content

[0004] The purpose of this application is to provide a drawer-type iron remover with a self-cleaning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides a drawer-type magnetic separator with a self-cleaning function, using the following technical solution: A drawer-type iron remover with self-cleaning function includes a filter chamber, a cleaning chamber, and an iron removal device. The iron removal device is disposed in the cleaning chamber and can move into the filter chamber. The iron removal device includes a support frame, magnetic rods, scrapers, cleaning retaining rings, pull rods, and stop blocks. The support frame is slidably disposed in the cleaning chamber. Several magnetic rods are uniformly fixed on the side wall of the support frame near the filter chamber. Multiple rows of square channels are opened between the filter chamber and the cleaning chamber corresponding to the positions of the magnetic rods. Sealing gaskets are fixed on the side walls of the square channels near the cleaning chamber. The scrapers are disposed between the sealing gaskets and the support frame, and cleaning retaining rings are installed on the scrapers corresponding to the positions of the magnetic rods. The cleaning retaining rings are matched and disposed on the magnetic rods. Stop blocks are symmetrically fixed on the outer walls of both sides of the filter chamber. Pull rods are movably inserted through the stop blocks. Limiting protrusions are fixed to the ends of the pull rods. One end of the pull rod extends into the cleaning chamber and is fixed to the scrapers. Cylinders are symmetrically fixed on both sides of the filter chamber, and the piston rods of the cylinders extend into the cleaning chamber and are fixed to the support frame.

[0006] The scraper includes a left pressure plate, a middle retaining plate, and a right pressure plate. The left pressure plate, the middle retaining plate, and the right pressure plate are fixed to each other by screws. One end of the pull rod is fixed to the right pressure plate. The left pressure plate can abut against the sealing gasket. The left pressure plate and the right pressure plate have through holes corresponding to the position of the magnetic rod. The middle retaining plate has a mounting hole for placing the cleaning retaining ring corresponding to the position of the through hole. The diameter of the mounting hole is larger than the diameter of the through hole.

[0007] Preferably, to prevent iron impurities from clogging the through holes, the through holes on the left pressure plate are frustum-shaped.

[0008] The tip of the magnetic rod located inside the filter chamber is a non-magnetic region.

[0009] Preferably, in order to ensure smooth operation of the scraper, two tie rods are symmetrically and movably mounted on the stop block.

[0010] In summary, this application includes at least one of the following beneficial technical effects: the drawer-type iron remover with self-cleaning function has a more reasonable layout. By integrating the scraper onto the magnetic rod and using the limiting of the pull rod to make the magnetic rod and the scraper move relative to each other, the iron impurities on the magnetic rod are removed. The cleaning efficiency is high, the cleaning effect is good, the manufacturing cost is low, and it is easy to maintain. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0018] This application discloses a drawer-type iron separator with a self-cleaning function, referring to... Figure 1-5 The system includes a filter chamber 1, a cleaning chamber 2, and an iron removal device 3. The iron removal device 3 is located inside the cleaning chamber 2 and can move into the filter chamber 1. The iron removal device 3 includes a support frame 31, magnetic rods 32, scrapers 33, a cleaning retaining ring 34, a pull rod 35, and a stop block 36. The support frame 31 is slidably disposed inside the cleaning chamber 2. Several magnetic rods 32 are evenly fixed on the side wall of the support frame 31 near the filter chamber 1. The tips of the magnetic rods 32 inside the filter chamber 1 are non-magnetic areas. Multiple rows of square channels are opened between the filter chamber 1 and the cleaning chamber 2 corresponding to the positions of the magnetic rods 32. 11. A sealing gasket 21 is fixed on the side wall of the square channel 11 near the cleaning chamber 2. A scraper 33 is disposed between the sealing gasket 21 and the support frame 31. A cleaning retaining ring 34 is installed on the scraper 33 at the position corresponding to the magnetic rod 32. The cleaning retaining ring 34 is matched and disposed on the magnetic rod 32 (the cleaning retaining ring 34 and the magnetic rod 32 are tightly fitted). Stop blocks 36 are symmetrically fixed on the outer walls of both sides of the filter chamber 1. A pull rod 35 is movably inserted through the stop block 36. A limit protrusion ring 37 is fixed at the end of the pull rod 35. One end of the pull rod 35 extends into the cleaning chamber 2 and is fixed to the scraper 33. Cylinders 4 are symmetrically fixed on both sides of the filter chamber 1. The piston rod of the cylinder 4 extends into the cleaning chamber 2 and is fixed to the support frame 31.

[0019] Reference Figure 5 The scraper 33 includes a left pressure plate 331, a middle retaining plate 332 and a right pressure plate 333. The left pressure plate 331, the middle retaining plate 332 and the right pressure plate 333 are fixed to each other by screws. One end of the pull rod 35 is fixed to the right pressure plate 333. The left pressure plate 331 can abut against the sealing gasket 21. The left pressure plate 331 and the right pressure plate 333 have through holes at the positions corresponding to the magnetic rod 32. The middle retaining plate 332 has a mounting hole 3321 for placing the cleaning retaining ring 34 at the position corresponding to the through hole. The diameter of the mounting hole 3321 is larger than the diameter of the through hole. To prevent iron impurities from clogging the through holes, the through holes on the left pressure plate 331 are frustoconical, which greatly improves the scraping efficiency.

[0020] To ensure the smooth operation of the scraper 33, two tie rods 35 are symmetrically and movable on the upper and lower sides of the stop block 36.

[0021] The implementation principle of a drawer-type iron separator with self-cleaning function in this application embodiment is as follows: During normal iron removal operation, cylinder 4 is in the retracted state, pulling the support frame 31 to push the scraper 33 to abut against the sealing gasket 21. When the material passes through the filter chamber 1, the material comes into contact with the magnetic rod 32, and the magnetic rod 32 can adsorb iron impurities in the material.

[0022] After working for a period of time, when the magnetic rod 32 needs to be cleaned, the cylinder 4 extends and pushes the support frame 31 to move the magnetic rod 32 into the cleaning chamber 2. Under the friction of the cleaning retaining ring 34, the scraper 33 also moves into the cleaning chamber 2 along with the magnetic rod 32 until the limiting protrusion 37 at the end of the pull rod 35 is limited by the stop block 36, and the scraper 33 stops moving. At this time, the magnetic rod 32 continues to move into the cleaning chamber 2. The cleaning retaining ring 34 blocks iron impurities on the magnetic rod 32. Excessive iron impurities will fall into the cleaning chamber 2. Finally, the remaining iron impurities will also lose their attraction in the non-magnetic area at the end of the magnetic rod 32 and fall into the cleaning chamber 2. The cleaning effect is high.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
