Horizontal spiral discharge sedimentation filtration centrifuge and secondary separation process thereof

Abstract

The invention relates to a horizontal spiral discharge sedimentation filtration centrifuge. The horizontal spiral discharge sedimentation filtration centrifuge comprises a drum part, a spiral materialpusher, a machine base and a cover shell, wherein the cover shell is arranged on the machine base; a drum component is arranged in the cover shell, the drum component is internally provided with thespiral material pusher, and the drum component comprises a straight-section drum, a butt-joint flange drum and a screen drum which are sequentially arranged from left to right; a screen is arranged inthe screen drum, and the butt-joint flange drum is provided with a conical cavity; the spiral material pusher comprises spiral material pusher components I and spiral material pusher components II, and seam allowances of the spiral material pusher components I and the spiral material pusher components II are in fit connection; the spiral material pusher components I are positioned in the straight-section drum and the butt-joint flange drum, and material feeding bins and material feeding holes are formed in the spiral material pusher components I; and the spiral material pusher components II are positioned in the screen drum, and a plurality of through holes are formed in the inner walls of spiral material pusher components II. The invention further discloses a secondary separation processof the horizontal spiral discharge sedimentation filtration centrifuge. The horizontal spiral discharge sedimentation filtration centrifuge has the beneficial effects that the separation effect is improved, the liquid outlet rate is high, the leakproofness is good, and the maintenance cost is low.

Description

technical field [0001] The utility model relates to the technical field of centrifuges, in particular to a horizontal spiral unloading sedimentation filter centrifuge and its secondary separation process. Background technique [0002] Horizontal spiral unloading decanter centrifuge is an automatic equipment widely used in continuous feeding, separation and unloading in chemical, sewage, medical, food and other industries. The working principle of this type of centrifuge is: the drum and the screw rotate at a high speed in the same direction at a certain differential speed, and the material continuously enters the feeding bin of the screw pusher from the feeding pipe, and enters the drum after acceleration. Under the action of centrifugal force, the heavier The solid phase deposits on the drum wall to form a sediment layer. The screw pusher continuously pushes the deposited solid phase to the cone section of the drum, and is discharged out of the machine through the slag dis...

AI Technical Summary

Problems solved by technology

[0003] At the same time, the oil yield of the existing horizontal spiral unloading sedimentation centrifuge used in the hot pot bottom material industry has basically reached the bottleneck, and the oil yield cannot be further improved; in addition, the residue in the drum deteriorates, which affects the problem of the next use increasingly prominent

[0004] Now, by combining the advantages of horizontal screw discharge sedimentation centrifuge and piston pusher centrifuge, a new type of horizontal screw discharge sedimentation filter centrifuge and its secondary separation process are designed, which can perfectly solve the above problems. And there is no similar equipment in the market
