Metal-rubber composite flow channel of separator

Abstract

The invention relates to a metal-rubber composite flow channel of a separator. The metal-rubber composite flow channel comprises a rotating drum body and a rotating drum body rack arranged outside the rotating drum body. An annular arc-face elastic piece is arranged on the inner side, close to a slag discharging outlet of the rotating drum body, of the rotating drum body rack. An annular elastic lining with the U-shaped longitudinal section are arranged on the inner wall of a slag discharging flow channel body at the bottom of the rotating drum body rack. A drum of the separator is simple in design and low in cost, the cell survival rate at the time of separating of cells from materials can be effectively increased. The cell survival rate of the separator in separating of the cells from the materials is about 10% before using the structure and increased to 60%-80% after using the metal-rubber composite flow channel.

Description

technical field [0001] The invention relates to a metal-rubber compound flow path of a separator, especially suitable for the design of a drum of a disc-type separator for cell materials such as chlorella, and belongs to the field of separators. Background technique [0002] Disc separator is a high-speed sedimentation centrifuge, which can quickly and effectively separate the mixture of liquid and solid with high speed and strong centrifugal force. Due to its high-efficiency separation, it is widely used in ships, food, medicine, etc. , chemical, textile and environmental protection industries. For cell-based materials, the effective components after separation are solid phase cells, that is, the slag phase that comes out through slag discharge; due to the high-speed rotation of the drum of the separator, the solid phase cells are discharged at a very high speed, and the inner flow channel of the drum is metal The material is subject to a large shear force when the separat...

AI Technical Summary

Problems solved by technology

For cell materials, the effective components after separation are solid phase cells, that is, the slag phase that comes out through slag discharge; due to the high-speed rotation of the drum of the separator, the solid phase cells are discharged at a very high speed, and the inner flow channel of the drum is made of metal. Material, when the separator is rotated and collided at high speed, it is subjected to a large shear force, which can easily lead to cell wall death and loss of activity
