Wet and dry sieve shaker for laboratory

Abstract

The invention discloses a wet and dry sieve shaker for a laboratory. The wet and dry sieve shaker comprises a base, a rack, a vibration bracket, a vibration motor, a vibration connecting rod, a vibration spring, a retainer ring, a locking slide rod, a water channel and a control panel, wherein the rack and the base are welded into a whole, the vibration bracket is connected with the rack through the vibration spring, the vibration motor is fixed on the vibration bracket, and the vibration frequency of the vibration motor is subjected to stepless regulation through a frequency converter. One end of the vibration connecting rod is fixed on the vibration bracket, the retainer ring is fixed at the other end of the vibration connecting rod, and the locking slide rod can slide up and down on the vibration connecting rod. The water channel is arranged on the base and is right below the retainer ring. The control panel is located on the rack, can control the frequency converter to regulate the vibration frequency of the vibration motor, and has a timing function. The wet and dry sieve shaker is simple in structure, is convenient to operate, and works reliably, manual work is replaced to carry out wet sieving, the labor intensity is reduced, the working efficiency is improved, the wet and dry sieve shaker is suitable for both dry sieving and wet sieving, one sieve shaker is used for two purposes, and the rate of equipment utilization is increased.

Description

technical field [0001] The invention relates to a vibrating sieve machine, in particular to a laboratory wet and dry vibrating sieve machine. Background technique [0002] In many fields such as coal preparation, mineral processing, chemical industry, etc., it is often necessary to carry out screening test analysis on fine materials to determine the content distribution of each particle size component. Since fine materials are easy to agglomerate, dry sieving is more difficult, so wet sieving is often used for powders below 200 mesh. Most of the existing vibrating sieve machines are dry vibrating sieve machines, which are not suitable for wet sieving. Traditional wet screening is mostly manual work, which is labor-intensive and extremely low in efficiency. Contents of the invention [0003] The object of the present invention is to provide a laboratory vibrating sieve machine for wet and dry use, which is suitable for both dry and wet sieving, has a simple structure and ...
