Small-scale screening device

Abstract

The invention relates to a small-scale screening device which is formed by a screening groove, a screen mesh, an outlet material baffle, a support, a rotating shaft, a motor and the like. The screening groove is formed by welding a semicircular cylinder and an end cover and is supported by the rotating shaft to complete pendular motion; the screen mesh is fixed in a rectangular screen mesh frame and installed in the middle of the screening groove in a detachable mode, and screen meshes with different screen holes are easy to replace; the outlet material baffle is installed on the periphery of the screening groove and is welded together with the support, a certain interval or gap is formed between the inner wall of the outlet material baffle and the outer wall of the screening groove, and overall swinging of the screening groove is not affected; the motor is connected with the rotating shaft through a circuit, and swinging frequency and amplitude of the screening groove are regulated through the motor. The screening device can effectively control standing time of materials in the screening groove on the screen mesh, blocking phenomena are not easily formed, the purpose of screening is rapidly realized, regulation performance is good, operation is stable, and the screening device can be widely applied to screening of the related industries of particles in food, medicine, the chemistry industry, the light industry and the like and is utilized on occasions where liquid and solid are rapidly separated.

Description

technical field

[0001] The invention relates to a small screening device, in particular to a swing type screening device which controls the swing frequency of a screening tank through a motor, and belongs to the field of particle classification or powder filtration. Background technique

[0002] The traditional screening device is a device that completes the screening through the size difference between the sieve hole diameter and the screened particles. The purpose of size particles. Its functions also include drying of washed vegetables, rapid separation of waste liquid and residue, etc. At present, most of the screening devices produced in China are up and down reciprocating vibration type, the local area of ​​the material stays too long, the screen holes are easy to block, the adjustment performance is poor, and the production efficiency is low; there are also large-scale devices with complex structures and high costs. , It is not suitable for the screening purpose of ...
