Horizontal spiral centrifuge

Abstract

The invention relates to a decanter centrifuge, comprising a screw pusher (1), a rotating drum (2) and a motor (3), and the motor (3) is used to drive the rotating drum (2) and the screw pushing device (1) Rotate on the same axis and in the same direction at the preset speed difference. There is a cavity in the drum (2). The central axes of the screw pusher (1) and the drum (2) are the same straight line. The screw pusher (1) Part is located inside the drum (2), and the screw propeller (1) includes an integral part formed by the discharge part (4) and the liquid discharge part (5), as well as the screw blade (6), the discharge part (4) and the liquid discharge part Both parts (5) are provided with cavities, the discharge part (4) and the liquid discharge part (5) are not connected, the discharge part (4) is provided with a discharge port (7), and the liquid discharge part (5) is provided with a liquid First outlet (8) and second outlet (9) for liquid. The decanter centrifuge provided by the invention has better solid-liquid separation effect and can be used for centrifugal separation and purification of montmorillonite in the production process of high-purity montmorillonite.

Description

technical field [0001] The present invention relates to a solid-liquid separation device, in particular to a decanter centrifuge. Background technique [0002] Montmorillonite is a layered mineral composed of extremely fine particles of hydrous aluminosilicate. It is widely used in medicine. It can be used as a pharmaceutical carrier, a controlled release agent, and has an antidiarrheal effect. Montmorillonite is used in storage There are also good applications in breeding, especially the yellow and white scours of piglets and suckling pigs, and diarrhea of ​​rabbits. It plays a preventive role, and montmorillonite can also be used as the best mold remover for feed. [0003] In the production process of high-purity montmorillonite, decanter centrifuges are often used for centrifugal separation and purification, but the centrifuges commonly used in the market now, in the centrifugal separation and purification of montmorillonite, there is a solid content in the separated liqu...

Problems solved by technology

[0003] In the production process of high-purity montmorillonite, decanter centrifuges are often used for centrifugal separation and purification, but the centrifuges commonly used in the market now, in the centrifugal separation and purification of montmorillonite, there is a solid content in the separated liquid More, the solid-liquid separation is not complete, and the problem of failing to meet the process requirements

[0004] The "decanter centrifuge" disclosed in Chinese Patent No. 201110029868.0 discloses a decanter centrifuge, which includes a screw pusher and a drum, and grooves with a wave-shaped structure are arranged on the inner wall of the drum. The solid-liquid mixture collides on the groove on the inner wall of the drum. Due to the different quality of solid and liquid, the direction and distance of rebound after hitting the groove on the inner wall of the drum are different, so that the solid-liquid separation is more thorough. However, in the actual application process, The effect of solid-liquid separation is hardly improved
