Horizontal spiral unloading sedimentation centrifuge of squeezing baffle plate structure

Abstract

The invention provides a horizontal spiral unloading sedimentation centrifuge of a squeezing baffle plate structure. The horizontal spiral unloading sedimentation centrifuge of the squeezing baffle plate structure comprises a cylinder; a spiral main shaft is arranged in the cylinder; the cylinder consists of a straight cylinder and a conical cylinder; the spiral main shaft consists of a straight section shaft and a conical section shaft; the intersection of the straight section shaft and the conical section shaft is arranged in the straight cylinder; the conical section shaft is welded with aconnecting ring plate; the connecting ring plate is connected with a splashed sleeve; the splashed sleeve consists of a first conical sleeve and a second conical sleeve; one end of the first conical sleeve is welded with the connecting ring plate, and the other end is welded with the conical section shaft; one end of the second conical sleeve is welded with the connecting ring plate, and the otherend is welded with the straight section shaft; spiral blades are welded on the splashed sleeve and the straight section shaft; a spiral channel is formed between the cylinder and the spiral main shaft; and a squeezing baffle plate is welded in the intersection of the first conical sleeve and the second conical sleeve. The slag discharge capacity of the centrifuge is improved; and the blockage cleaning period is prolonged.

Description

technical field [0001] The invention belongs to the technical field of centrifuges, and in particular relates to a horizontal screw discharge sedimentation centrifuge with a pressing baffle structure. Background technique [0002] For materials with soft compressibility in the solid phase, the general horizontal screw discharge decanter centrifuge adopts a large cone angle (15°-20°) and a squeeze baffle structure. This centrifuge uses a single vertical squeeze baffle to The separation liquid and separation slag are separated on both sides, and the squeeze baffle is welded in the middle of the spiral channel with a single ring plate to separate the spiral channel. The squeeze baffle plays the role of squeezing solids and isolating liquid, and at the same time cooperates with the large cone angle structure , can greatly increase the effective volume of the centrifuge, that is, improve the processing capacity of the centrifuge. However, due to the dead angle between the press ...

AI Technical Summary

Problems solved by technology

However, due to the dead angle between the press baffle, the screw blade and the screw shaft, during the working process of the centrifuge, a large amount of solid waste will be stored in this dead angle, and it is difficult to completely clean it during the centrifuge cleaning process.

When the accumulated material is not evenly distributed, the dynamic balance of the centrifuge will be destroyed, resulting in greater vibration during the operation of the centrifuge. At the same time, long-term accumulation of some food materials will cause odor and deterioration.
