Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silicon powder processing, specifically to a screening device for silicon powder processing. BACKGROUND

[0002] Silicon powder, also known as micro silicon powder, is a kind of industrial dust collected and processed by special capturing device during the process of industrial electric furnace smelting industrial silicon and silicon iron. The silicon powder needs to be screened during processing. The caked part is difficult to be screened, so a new type of silicon powder processing and screening device is needed.

[0003] The existing patent with the publication number CN217392959U, named "silicon powder screening device", discloses a silicon powder screening device, which includes a first sieve body and a first sieve plate. The first sieve body includes a first shell and a first lining. The first lining is arranged inside the first shell. The first lining includes a main body and a protruding part. The main body covers the inner wall of the first shell. The protruding part is arranged on the side of the main body away from the inner wall of the first shell. The edge of the first sieve plate is a stepped structure. The edge of the first sieve plate is arranged on the protruding part. The stepped surface formed by the protruding part and the stepped structure is connected. By arranging the first lining inside the first shell, the main body of the first lining covers the inner wall of the first shell, so that the silicon powder only contacts the first lining and does not rub between the first sieve body to produce particles that pollute the silicon powder, ensuring the high purity of the silicon powder. The protruding part of the first lining and the stepped surface formed by the stepped structure are connected, so that the first sieve plate can be better positioned, facilitating the installation and removal of the first sieve plate. The first sieve plate is not easy to separate from the first lining.

[0004] The above device vibrates when the vibration motor starts, so that the shell, support frame, first sieve body, first sieve plate, second sieve body and second sieve plate are vibrated to screen the silicon powder. However, the silicon powder is very small and is easy to caking in a humid environment, which affects the efficiency of screening and cannot meet the needs of people. In view of the above situation, technical innovation is made on the basis of the existing screening device. UTILITY MODEL CONTENTS
