Description

Technical Field

[0001] This utility model relates to the field of sedimentation centrifuges, specifically a sedimentation centrifuge for impurity separation. Background Technology

[0002] A sedimentation centrifuge is a type of centrifuge that performs a centrifugal sedimentation process. During operation, the suspension forms an annular liquid layer along the drum wall under centrifugal force. The denser solid particles settle radially onto the drum wall, forming sediment. The clarified liquid is discharged through the drum overflow port, and the sediment is removed manually or mechanically. Commonly used, intermittent types include the three-legged sedimentation centrifuge and the horizontal scraper discharge sedimentation centrifuge, used for processing solid particles >5µm in size and solid-liquid phase density differences >500kg / m³. 3 And suspensions with a concentration of less than 10%.

[0003] For example, the key technical features of a horizontal spiral sedimentation centrifuge (authorization announcement number CN204933747U) are as follows: it includes a shell, a spiral pusher, a differential, and a bearing seat. The end of the spiral pusher extends to the outside of the shell and is connected to the differential. A rotating drum is provided outside the spiral pusher, and a separation chamber is formed between the rotating drum and the inner wall of the shell. A feed inlet and a solid phase outlet are provided at the right end of the rotating drum, and a liquid phase outlet is provided at the left end of the shell. A defoaming plate for eliminating foam in the liquid is provided at the end of the spiral pusher near the liquid phase outlet. The defoaming plate is slidably connected to the spiral pusher, and an adjusting element for locking the position of the defoaming plate is provided between the defoaming plate and the spiral pusher.

[0004] The above-mentioned device solves the problem of poor defoaming effect of the defoaming plate in the existing horizontal spiral sedimentation centrifuge by providing an adjusting component for locking the position of the defoaming plate. However, the above-mentioned device does not have a device to capture fine particles that are not completely separated by the centrifuge and recover valuable solid phases. As a result, the above-mentioned device is relatively wasteful in recovering valuable solid phases because it does not have a device to capture fine particles that are not completely separated by the centrifuge.
