Vibration filtering centrifugal machine

Abstract

The invention belongs to the technical field of centrifugal machines, and particularly relates to a vibration filtering centrifugal machine. The vibration filtering centrifugal machine comprises a machine base, a filtering cylinder assembly and a driving mechanism; the filtering cylinder assembly is fixedly connected with the machine base and comprises a feeding cylinder, a liquid collecting cylinder and a material collecting cylinder which are sequentially arranged in a sleeving mode from inside to outside, a gap exists between the feeding cylinder and the liquid collecting cylinder as well as between the liquid collecting cylinder and the material collecting cylinder, the feeding cylinder is sleeved with a rotatable screening basket, and the screening basket is located between the feeding cylinder and the liquid collecting cylinder and provided with a main shaft connected with the driving mechanism; the driving mechanism is fixedly connected with the machine base, the main shaft is connected with the machine base through a connecting assembly, and the main shaft can rotatably, axially and elastically move relative to the machine base; and the main shaft is provided with a vibration exciter, the main shaft and the screening basket are driven by the driving mechanism to rotate, and axial vibration of the main shaft and the screening basket is achieved through the vibration exciter. According to the vibration filtering centrifugal machine, the whole structure is simple, and little parts are arranged; and the vibration exciter directly acts on the screening basket through themain shaft, the reliability is high, vibration participating parts are reduced, and energy losses are reduced.

Description

technical field [0001] The invention belongs to the technical field of centrifuges, in particular to a vibrating filter centrifuge. Background technique [0002] A centrifuge is a machine that uses centrifugal force to separate a mixture of liquid and solid particles. The vibrating filter centrifuge is a filter centrifuge with axial vibration added. There are currently two vibrating filter centrifuges, vertical and horizontal. The principle of the vibrating filter centrifuge is: the sieve basket not only rotates around the axis, but also reciprocates linearly along the axis. In this kind of centrifuge, the axial vibration of the screen basket is very important. On the one hand, it makes the material on the screen surface move from the small end of the screen basket to the large end. On the other hand, the sliding speed of the material on the screen surface is gradually slowed down, causing the material layer on the screen surface to be tight and sometimes loose, which int...

AI Technical Summary

Problems solved by technology

Therefore, the mechanical structure of the axial vibration transmitted from the exciter to the screen basket is complex, with many parts, large vibration quality, low efficiency, and large energy loss, so there are many faults and poor reliability. The main manifestations are: (1) The vibration parameters are unstable, Frequent and difficult adjustments; (2) The main bearings, springs, connecting bolts and other components are subject to large shock forces, which are easily damaged, the support is easy to crack, and the box body leaks oil seriously; (3) Serious problems such as loud noise

[0005] At present, the screen basket of the known filter centrifuge, the filtration area is only the surface area of ​​the screen basket, so the traditional screen basket has a small filtration area and low efficiency
