TECHNICAL FIELD
[0001] The application relates to the technical field of roll skin cleaning, in particular to a roll skin cleaning device for a dry magnetic separator. BACKGROUND
[0002] With the development and utilization of mineral resources, dry magnetic separation technology is widely used in the separation of metallic minerals, especially in the separation of iron ore, aluminum ore, titanium ore and other minerals. As the core equipment, the dry magnetic separator has high efficiency in the separation of metallic minerals, and plays an important role in the industries of mineral processing, metallurgy and chemical industry. The performance of the magnetic separator mainly depends on the adsorption capacity of the magnetic roller, and the surface of the roll skin of the magnetic roller will adhere to a large amount of mineral impurities during long-term operation, which will gradually reduce the adsorption capacity and affect the magnetic separation effect. If not cleaned in time, the impurities on the roll skin will not only reduce the working efficiency of the magnetic separator, but also cause interference and damage between the equipment, and even cause equipment failure and stop production, affecting the production progress and benefits.
[0003] At present, the existing cleaning devices for magnetic separators have some deficiencies. The common cleaning methods mostly rely on manual intervention or simple mechanical cleaning methods, which not only have low efficiency, but also easily cause additional damage to the equipment, and the cleaning effect is unstable. In addition, due to the complex working environment of the magnetic separator, the operation conditions are poor, and the types and adhesion strength of the impurities change greatly, so the traditional cleaning method cannot flexibly cope with different situations, and cannot ensure long-term stable and efficient work. SUMMARY

DETAILED DESCRIPTION
[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the application clearer, the technical scheme of the embodiments of the application will be described clearly and completely below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are some embodiments of the application, but not all embodiments of the application. The components of the embodiments of the application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0020] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0021] like Figures 1 to 5 As shown, a dry magnetic separator magnetic roller skin cleaning device includes a base plate 101, a bracket 102 fixedly mounted on the base plate 101, a rotating shaft 103, a feed trough 106 and an impurity trough 107 fixedly mounted on the bracket 102, a side plate 104 rotatably mounted on the rotating shaft 103, a roller skin 105 fixedly mounted on the side plate 104, a slide frame 109 slidably mounted on the base plate 101, a collection frame 111 fixedly mounted on the slide frame 109, a cleaning frame 112 fixedly mounted on the collection frame 111, a scraper 115 slidably mounted on the collection frame 111, a protective shell 114, a buffer shaft 116 and a buffer spring 117 fixedly mounted on the scraper 115, the buffer spring 117 is also fixedly mounted on the collection frame 111, and the buffer shaft 116 is slidably connected to the collection frame 111.
[0022] Specifically, during magnetic separation, material is fed onto roller 105 through feed trough 106. Metal minerals are adsorbed by magnets 108 inside roller 105, while other impurities fall into impurity trough 107 for separation due to inertia. When the adsorbed metal minerals move below roller 105, the magnetic force of magnets 108 is insufficient to continue adsorbing them, so these metal minerals fall onto collection frame 111 by gravity. During this process, some material adheres to roller 105 and continues to rotate. As roller 105 rotates, a large amount of impurities accumulate on roller 105 after prolonged operation, reducing its surface adsorption force and causing interference with feed trough 106 and impurity trough 107, which in turn damages roller 105, feed trough 106, and impurity trough 107.
[0023] After a period of use, when there are many impurities adhering to the roller skin 105 or a large amount of metal minerals collected in the collection frame 111, the slide 109 is controlled to slide to the left on the base plate 101, thereby driving the collection frame 111 to move to the left. This causes the upper end of the scraper 115 on the collection frame 111 to contact the roller skin 105. Through the rotation of the roller skin 105 and the cooperation of the scraper 115, the scraper 115 scrapes off the impurities on the roller skin 105, which fall into the cleaning frame 112 and then fall into the collection trough 113 through the opening at the lower end of the cleaning frame 112 for collection.
[0024] If the impurities adhered to the roller skin 105 are more, the scraper 115 will not directly contact the roller skin 105 at the beginning, and after the scraper 115 scrapes part of the impurities, the collecting frame 111 is gradually controlled to move to the left, so that the upper end of the scraper 115 gradually approaches the roller skin 105, and if the impurities are strongly adhered, the impurities on the roller skin 105 will push the scraper 115 to slide downward on the collecting frame 111, and at the same time drive the buffer shaft 116 to slide downward on the collecting frame 111 and compress the buffer spring 117 on the buffer shaft 116.
[0025] As shown in Figure 5 , the scraper 115 is provided with a sliding part and a scraping part, and the sliding part is arranged on the sliding groove of the collecting frame 111.
[0026] Specifically, the impurities adhered to the roller skin 105 are scraped by the scraping part of the scraper 115, and when the scraper 115 contacts the impurities of the roller skin 105, the impurities of the roller skin 105 will exert a downward pushing force on the scraping part of the scraper 115, thereby pushing the sliding part of the scraper 115 to slide downward on the collecting frame 111, so that the scraper 115 can smoothly move to the predetermined position, and ensure that the impurities scraped from the roller skin 105 can completely fall into the cleaning frame 112.
[0027] As shown in Figure 5 , one end of the scraping part of the scraper 115 close to the roller skin 105 is arc-shaped, which reduces the damage of the scraping part to the roller skin 105.
[0028] Specifically, the scraping part of the scraper 115 is arc-shaped, which reduces the interference caused by the irregular shape of the impurities when the scraping part contacts the impurities of the roller skin 105, and ensures that the impurities can smoothly push the scraper 115 to slide downward, and the scraper 115 can smoothly slide horizontally, thereby improving the smoothness of the movement of the scraper 115 and ensuring the stable operation of the cleaning device.
[0029] As shown in Figure 4 , the collecting frame 111 is fixedly provided with a protective plate 118, and the protective plate 118 contacts the scraping part of the scraper 115.
[0030] Specifically, the side of the sliding part of the scraper 115 close to the collecting frame 111 is protected by the protective plate 118, so that the small metal minerals falling from the roller skin 105 cannot enter the connection between the sliding part of the scraper 115 and the sliding groove of the collecting frame 111, thereby affecting the sliding of the scraper 115.
[0031] As shown in Figure 4 , the bottom plate 101 is provided with 128.
[0032] Specifically, the impurities scraped off by the scraper 115 fall on the cleaning frame 112, and the cleaning frame 112 makes the impurities slide to the collecting frame 128 through the opening and the inclined surface for collection and transportation.
[0033] As shown in the drawings, the collecting frame 111 is provided with an outwardly expanded structure to adapt to the size of the roller skin 105. Figure 4
[0034] Specifically, the outwardly expanded structure of the collecting frame 111 avoids the movement of the collecting frame 111, so that the metal minerals can fall into the collecting frame 111 when the collecting frame 111 is in the initial position, and the interference between the collecting frame 111 and the roller skin 105 can be avoided when the collecting frame 111 moves.
[0035] When the scraper 115 moves to the appropriate position, the scraper 115 pushes the buffer spring 117 to slide downward on the collecting frame 111 and compresses the buffer shaft 116. After reaching the appropriate position, the impurities on the roller skin 105 are scraped off by the scraper 115. During the scraping process, the impurities on the roller skin 105 gradually fall off, and the scraper 115 gradually rises under the action of the buffer shaft 116, so that the scraping part of the scraper 115 maintains close contact with the impurities on the roller skin 105, thereby ensuring the cleaning effect of the impurities.
[0036] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
