Vinasse waste liquid centrifuge

Abstract

The invention discloses a vinasse waste liquid centrifuge. The vinasse waste liquid centrifuge comprises a cover, a drum, a spiral, a differential, a main motor and a feeding pipe; the drum is positioned in the cover; the spiral is positioned in the drum; spiral blades are arranged on the outer surface of the spiral; the main motor drives the differential to drive the drum; the drum is connected with the spiral through the differential; a material cavity is formed in the spiral; a pipe orifice of the feeding pipe extends into the material cavity; a discharge port is formed in the wall surfaceof the material cavity, is oblong and is aslant arranged; and the inclined direction of the discharge port is consistent with the inclined direction of the spiral blades. In the centrifuge, the discharge port is aslant arranged, and the inclined direction of the discharge port is kept consistent with the inclined direction of the spiral blades, so that the scour and the wear to the spiral blades in the extrusion process of solid materials are reduced, and the service life of the centrifuge is prolonged.

Description

technical field [0001] The invention relates to a centrifuge, in particular to a centrifuge used for solid and liquid separation of vinasse waste liquid. Background technique [0002] The centrifuge uses the principle of centrifugal sedimentation to separate solids and liquids. It is widely used in tailings water, coal washing, PVC production, urban and industrial wastewater treatment, and wine making. It is of great significance to national production. [0003] figure 1 It is a structural schematic diagram of a centrifuge in the prior art, including a machine cover 1, a drum 2, a screw 3, a differential 4, a main motor 5, an auxiliary motor 7 and a feed pipe 6; the drum 2 is located in the machine cover 1, and the screw 3 is located in the drum 2, and the outer surface of the screw 3 is provided with a spiral blade 31; the main motor 5 drives the differential 4, drives the drum 2 to rotate, and the drum 2 and the screw 3 are connected through the differential 4; the auxili...

AI Technical Summary

Problems solved by technology

[0004] The defect of this centrifuge is: (1) the solid material coming out from the discharge port directly impacts on the screw blade, which makes the wear of the screw blade serious; (2) the screw is an integrated structure, and the discharge port of the material chamber is in the In long-term use, it is easy to be repeatedly worn by the solid material in the mixed material, resulting in the failure of the entire screw drum; (3) The solid material in the drum is easy to accumulate in the upper part of the first chamber after being thrown out. The outer wall of the drum is rubbed repeatedly, which makes the drum wear seriously; (4) The main motor and the auxiliary motor are arranged at both ends of the hood, and the length of the entire horizontal centrifuge is large, which is not easy to install
