Description

Technical Field

[0001] This utility model relates to the field of alumina powder production technology, and in particular to a filtration device for alumina powder production. Background Technology

[0002] During the production of alumina, other impurities may be introduced into the raw materials, such as metal particles, non-alumina chemicals, or other contaminants. These impurities can affect the quality, performance, and subsequent application of alumina powder. Filtration can effectively remove these impurities, ensuring that the product purity meets the required standards.

[0003] Existing filtration devices for alumina powder production are cumbersome and time-consuming to replace internal filter screens during installation and use, which affects the efficiency of the filtration device. Secondly, existing screening devices tend to accumulate powder during feeding, causing filter screen blockage and affecting the filtration efficiency of the powder, which brings certain adverse effects to the user experience. In order to overcome the shortcomings of the existing technology, we propose a filtration device for alumina powder production. Utility Model Content

[0024] Through the adjustable screw 10 and hard brush 11, the motor 12 drives the transmission gear 13 to rotate, so that the two sets of hard brushes 11 can move left and right to clean the filter screen inside the filter screen frame 8. The hard brushes 11 can also flatten the accumulated powder and improve the filtration efficiency.

[0025] It should be noted that this utility model is a filtration device for alumina powder production. In use, the user feeds the powder through the feed port 3. The motor 12 drives the transmission gear 13 to rotate, and the transmission gear 13 drives the transmission chain 14 to transmit to another set of transmission gears 13, so that the two sets of transmission gears 13 rotate synchronously, allowing the two sets of hard brushes 11 to move left and right to clean the filter screen inside the filter screen frame 8.
