Pushing driving device of mechanical pushing centrifuge

Abstract

The invention discloses a pushing driving device of a mechanical pushing centrifuge, and relates to the technical field of mechanical pushing centrifuges. The pushing driving device of the mechanicalpushing centrifuge adopts a motor driving speed reducer to drive a transmission device to move front and back; the transmission device and a connected shaft sleeve are rotated; the shaft sleeve drivesa pushing shaft to slide back and forth; a guide key is arranged between the pushing shaft and a hollow shaft, so that the pushing shaft slides back and forth in the hollow shaft in a path of the guide key; the pushing shaft drives a first-grade rotating drum bottom to drive a first-grade rotating drum to move back and forth; and a pushing piece is of a fan annular structure to stop materials from leaking in mother liquor in centrifugal treatment. The pushing driving device of the mechanical pushing centrifuge is simple in structure, lower in production and maintenance cost and simple in positioning and guide structure of the pushing shaft, prevents the oil leakage phenomenon, can achieve the effects needed by the reciprocating motion of the first-grade rotating drum; the pushing piece issimple in structure; and materials are not easy to leak into the mother liquor in centrifugal treatment.

Description

technical field [0001] The invention belongs to the technical field of a mechanical pushing centrifuge, and in particular relates to a pushing driving device of a mechanical pushing centrifuge. Background technique [0002] The pusher driving device in the mechanical pusher centrifuge is usually divided into two types: mechanical or hydraulic. The pusher drive device rotates at the same speed and in the same direction as the drum, and pushes the material back and forth with the pusher plate. At present, the mechanical pusher driving device uses a speed-regulating motor to drive the reducer, and then uses the eccentric wheel output on the reducer to drive the connecting rod, and the connecting rod is connected with the push rod coupling to make forward and backward motions to achieve the purpose of pushing materials. Although the structure of the device is simple, there is a lot of wear between the mating parts, the pusher shaft cannot be positioned and guided, and the rotati...

AI Technical Summary

Problems solved by technology

[0004] The invention solves the problem of complex structure, high manufacturing and maintenance costs, complicated positioning and guiding structure of the pusher shaft, and easy oil leakage of the main bearing in the prior art, and the pusher driving device of the present invention realizes that the original separation principle is not changed. At the same time change the reciprocating motion drive mode of the drum

The invention also overcomes the problem that the structure of the pushing piece is complex and the material is easily leaked into the mother liquor during centrifugal treatment
