Description

Technical Field

[0001] This utility model relates to the field of activated carbon production, and in particular to a sand removal device in activated carbon production. Background Technology

[0002] Activated carbon is a porous carbon material with a high specific surface area and abundant functional groups, thus possessing strong adsorption capacity. It is widely used in food processing, pharmaceuticals, industrial applications, and water treatment. During the processing of activated carbon, a small amount of fine sand, dust, and other particles inevitably adhere to its surface. Direct processing can affect the quality of the subsequent activated carbon. Therefore, during activated carbon production, a sand removal device is usually used to remove sand and dust from the activated carbon. As shown in the activated carbon sand removal device disclosed on the China Patent Network (Announcement No. CN221335234U), when using this type of sand removal device, the activated carbon is poured into the sand removal box, and the motor and vibrator are started. The motor drives the spiral blades to rotate, which causes the activated carbon to tumble. At the same time, the vibrator vibrates, causing the filter plate to vibrate. The vibration of the filter plate causes the continuously tumbling activated carbon to vibrate and screen out the sand and dust on the activated carbon.

[0003] However, the aforementioned patented and existing activated carbon sand removal devices have some shortcomings: While existing methods using vibrating screens to remove sand from activated carbon offer good screening performance, the vibration can easily cause the activated carbon itself to break, resulting in sand and dust being screened out along with the activated carbon, affecting its quality and resulting in poor sand removal efficiency.
