Description

Technical Field

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

[0002] A rotary magnetic separator is an improved version of the grid magnetic separator. Its main function is to solve the problems of bridging and clogging that occur when traditional grid magnetic separators filter powdery materials with poor flowability. Rotary magnetic separators have a wide range of applications, including production lines in the food, food additive, pharmaceutical, fine chemical, lithium battery cathode and anode materials, pigment, carbon black, and flame retardant industries. The rotary magnetic separator uses a geared motor to drive a ring-shaped grid to rotate, effectively preventing bridging and clogging as materials flow through the separator, and efficiently removing iron impurities from loose, agglomerated materials.

[0003] One disadvantage of existing rotary magnetic separators compared to grid magnetic separators is their inability to self-clean. Because rotary magnetic separators require an additional geared motor to rotate the magnetic rod assembly, and lack the space for scraping devices and core / outer jacket separation mechanisms, most rotary magnetic separators require manual cleaning, resulting in lower iron removal efficiency. While some rotary magnetic separators on the market possess self-cleaning capabilities, their structures are complex and manufacturing costs are high. Therefore, the applicant has redesigned a simpler, easier-to-manufacture rotary magnetic separator with a self-cleaning structure. Utility Model Content

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

[0005] To achieve the above objectives, this application provides a rotary iron separator with a self-cleaning function, employing the following technical solution: A self-cleaning rotary iron remover includes a filter chamber, a cleaning chamber, a geared motor, and a rotary iron removal device. The rotary iron removal device is disposed within the filter chamber and is movable into the cleaning chamber. A connecting channel is provided between the filter chamber and the cleaning chamber. The rotary iron removal device includes a base plate, a rotating body, a magnetic rod, a scraper, a cleaning retaining ring, a telescopic key shaft, and a spring. The geared motor is disposed on the side of the filter chamber. The base plate is slidably disposed within the cleaning chamber, and the side of the base plate can seal against the end of the connecting channel. The rotating body is rotatably connected to the filter chamber. On the side of the substrate near the filter chamber, a plurality of magnetic rods are evenly mounted on the rotating body. A cleaning retaining ring is installed on the scraper corresponding to the position of the magnetic rod. The cleaning retaining ring is matched and set on the magnetic rod. One end of the telescopic key shaft is connected to the reduction motor, and the other end of the telescopic key shaft is fixed to the rotating body. A transmission block is fixed on the scraper corresponding to the position of the telescopic key shaft. A clearance hole is opened in the middle of the transmission block corresponding to the position of the telescopic key shaft. A spring is sleeved on the telescopic key shaft, and one end of the spring is fixed on the telescopic key shaft, and the other end of the spring is fixed to the transmission block. Cylinders are symmetrically arranged on both sides of the filter chamber. The piston tube of the cylinder can extend into the cleaning chamber, and the piston rod of the cylinder is fixed to the base plate.

[0006] Preferably, in order to ensure smooth transmission of the telescopic key shaft, a bearing seat is fixed on the side of the base plate away from the rotating body, and the rotating body is rotatably connected in the bearing seat.

[0007] A sealing gasket is fixed on the end face of the connection channel near the cleaning chamber, and the substrate can abut against the sealing gasket.

[0008] Preferably, the scraper includes a left pressure plate, a right pressure plate, and a middle retaining plate. The surfaces of the left and right pressure plates are provided with through holes corresponding to the positions of the magnetic rods. The middle retaining plate is provided with mounting holes for placing the cleaning retaining rings corresponding to the positions of the through holes. The diameter of the mounting holes is larger than the diameter of the through holes. The transmission block is disposed between the left and right pressure plates.

[0009] By adopting the above technical solution, the scraper blade has a detachable structure, which facilitates the replacement of the cleaning retaining ring and makes maintenance relatively simple.

[0010] Preferably, in order to avoid iron impurities accumulating in the through holes, the through holes on the left pressure plate are provided in a frustum shape.

[0011] The tip of the magnetic rod away from the rotating body is a non-magnetic region.

[0012] In summary, this application includes at least one of the following beneficial technical effects: the self-cleaning rotary iron remover has a compact structure and reasonable layout. The scraper moves relative to the magnetic rod by the stroke difference between the end of the telescopic key shaft and the spring, so that iron impurities on the magnetic rod are removed. The cleaning efficiency is high and the cleaning effect is good. Moreover, the telescopic key shaft and the spring are both conventional parts, with low manufacturing cost and easy maintenance.

[0020] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0021] This application discloses a rotary iron separator with a self-cleaning function, referring to... Figure 1-6The system includes a filter chamber 1, a cleaning chamber 2, a geared motor 3, and a rotary iron removal device 4. The rotary iron removal device 4 is located inside the filter chamber 1 and can move into the cleaning chamber 2. A connecting channel 11 is provided between the filter chamber 1 and the cleaning chamber 2. The rotary iron removal device 4 includes a base plate 41, a rotating body 42, magnetic rods 43, a scraper 44, a cleaning retaining ring 45, a telescopic key shaft 46, and a spring 47. The geared motor 3 is located on the side of the filter chamber 1. The base plate 41 is slidably located inside the cleaning chamber 2, and the side of the base plate 41 can seal against the end of the connecting channel 11. Specifically, a sealing gasket 111 is fixed on the end face of the connecting channel 11 near the cleaning chamber 2, and the base plate 41 can abut against the sealing gasket 111. The rotating body 42 is rotatably connected to the side of the base plate 41 near the filter chamber 1, and several magnetic rods are evenly installed on the rotating body 42. 43. A cleaning retaining ring 45 is installed on the scraper 44 at the position corresponding to the magnetic rod 43. The cleaning retaining ring 45 is matched and set on the magnetic rod 43 (the cleaning retaining ring 45 and the magnetic rod 43 are tightly fitted). In order to facilitate material discharge, the tip of the magnetic rod 43 away from the rotating body 42 is a non-magnetic area. One end of the telescopic key shaft 46 is connected to the reduction motor 3, and the other end of the telescopic key shaft 46 is fixed to the rotating body 42. A transmission block 48 is fixed on the scraper 44 at the position corresponding to the telescopic key shaft 46. A clearance hole is opened in the middle of the transmission block 48 at the position corresponding to the telescopic key shaft 46. A spring 47 is sleeved on the telescopic key shaft 46, and one end of the spring 47 is fixed on the telescopic key shaft 46. The other end of the spring 47 is fixed to the transmission block 48. When there is no pressure, the end of the spring 47 can extend into the cleaning chamber 2, and the direction of the elastic force of the spring 47 is in the direction of the spring 47 contraction. Cylinders 5 are symmetrically arranged on both sides of the filter chamber 1. The piston tube of the cylinder 5 can extend into the cleaning chamber 2, and the piston rod of the cylinder 5 is fixed to the base plate 41.

[0022] Reference Figure 2-4 To ensure smooth transmission of the telescopic key shaft 46, a bearing seat 6 is fixed on the side of the base plate 41 away from the rotating body 42, and the rotating body 42 is rotatably connected in the bearing seat 6.

[0023] Reference Figure 5-6 The scraper 44 includes a left pressure plate 441, a right pressure plate 442, and a middle retaining plate 443. The left pressure plate 441 and the right pressure plate 442 have through holes on their surfaces corresponding to the positions of the magnetic rod 43. The middle retaining plate 443 has mounting holes 4431 for placing the cleaning retaining ring 45 at the positions corresponding to the through holes. The diameter of the mounting holes 4431 is larger than the diameter of the through holes. The transmission block 48 is disposed between the left pressure plate 441 and the right pressure plate 442. The through hole on the left pressure plate 441 is frustum-shaped.

[0024] The scraper 44 has a detachable structure, which makes it easy to replace and clean the retaining ring 45 later, and the maintenance is relatively simple. At the same time, the through hole on the left pressure plate 441 is set in a frustum shape, which can prevent iron impurities from accumulating in the through hole and facilitate scraping.

[0025] The implementation principle of a self-cleaning rotary iron separator according to an embodiment of this application is as follows: During normal iron removal operation, the cylinder 5 is in a retracted state, which drives the base plate 41 to press against the end of the connecting channel 11. The reduction motor 3 drives the rotating body 42 to rotate via the telescopic key shaft 46. The rotating body 42 drives the magnetic rod 43 to rotate, thereby adsorbing iron impurities in the material flowing through the filter chamber 1.

[0026] When self-cleaning is required, the cylinder 5 simply extends to move the substrate 41 into the cleaning chamber 2. During this process, the spring 47 first releases pressure, and the scraper 44 moves into the cleaning chamber 2 together with the magnetic rod 43. After the spring 47 returns to its original position, the magnetic rod 43 continues to move into the cleaning chamber 2. At this time, the scraper 44 stops moving under the pulling force of the spring 47 (the pulling force of the spring 47 is greater than the friction between the cleaning retaining ring 45 and the magnetic rod 43). The cleaning retaining ring 45 can scrape off the iron impurities on the magnetic rod 43. 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 43 and fall into the cleaning chamber 2. The cleaning efficiency is high. In addition, the pulling force of the spring 47 can also give the scraper 44 a continuous kinetic energy, thereby improving the scraping effect of the cleaning retaining ring 45.

[0027] 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.
