Description

Technical Field

[0001] The utility model relates to the technical field of silicon carbide micropowder impurity removal devices, in particular to a silicon carbide micropowder impurity removal device. Background Art

[0002] Silicon carbide, also known as carbon silicon stone, diamond sand or refractory sand, is a refractory material made of quartz sand, petroleum coke (or coal coke) and sawdust through high-temperature smelting in a resistance furnace. Pure silicon carbide is a colorless and transparent crystal. Industrial silicon carbide is light yellow, green, blue or even black due to the type and content of impurities it contains. The transparency varies with its purity. Since silicon carbide micropowder is mainly used in the abrasive industry, there are special requirements for the classification of micropowder. Large particles of impurities cannot appear in the micropowder. Silicon carbide micropowder needs to be filtered during production to remove large particles of impurities. During the use of the existing silicon carbide micropowder filtering device, the impurities on the filter screen need to be manually cleaned, which increases the labor of personnel, brings inconvenience to the regular cleaning of the filter screen, and affects the efficiency of the later maintenance of the device. Therefore, we propose a silicon carbide micropowder impurity removal device.

[0003] The silicon carbide micropowder impurity removal device disclosed in the Chinese utility model patent application disclosure CN219616013U has the advantages of quickly cleaning impurities on the filter screen and reducing the workload of personnel, but the silicon carbide micropowder impurity removal device still has disadvantages: First, the silicon carbide micropowder impurity removal device uses a push plate to clean the impurities on the filter screen. In actual use, some granular impurities of appropriate size may just get stuck inside the filter holes on the filter screen, so it is not easy to scrape the push plate clean and need to be cleaned again later; Second, during the addition of silicon carbide micropowder, the silicon carbide micropowder may be caused to fly and stir up dust during the addition process because the silicon carbide micropowder is too fine, thereby causing unnecessary waste and affecting the working environment.

A feed port 12 is provided on the top of the screening box 2, and an opening and closing door 13 is rotatably connected to the inside of the feed port 12. A rotating rod 14 is fixedly connected to the front and rear surfaces of the opening and closing door 13, and a connecting rod 15 is fixedly connected to the side of the rotating rod 14. A torsion spring 35 is fixedly installed on the inner wall of the feed port 12, and the feed port 12 and the opening and closing door 13 are The two groups are symmetrically arranged on the top of the screening box 2. There are two torsion springs 35 in the front and rear and both are fixedly installed on the front and rear inner walls of the feed port 12. The bottom of the connecting rod 15 is fixedly connected to the top of the right side of the torsion spring 35. The opening and closing door 13 is rotatably connected to the torsion spring 35 on the front and rear inner walls of the feed port 12 through the rotating rod 14.
