Cement negative pressure sieve analysis instrument capable of achieving heat dissipation conveniently

Abstract

The invention discloses a cement negative pressure sieve analysis instrument capable of achieving heat dissipation conveniently, and relates to the field of cement processing. The cement negative pressure sieve analysis instrument comprises an instrument body, a storage box is installed at the bottom of the instrument body, a guide block is installed in the storage box, discharge ports are formedin the two sides of the storage box, a material falling port, a cavity and a guide port are formed in the lower portion in the instrument body, and baffles are fixed to the two sides in the cavity. Through arrangement of a third motor, a driving shaft, the material falling port, the cavity, the baffles, second motors, second reels, second pull ropes, the discharge ports, a rotating shaft and a partition plate, when shaking balls move to the uppermost part of the instrument body, a worker starts the third motor through an operation table, the third motor works to drive the driving shaft to rotate, the driving shaft rotates so as to drive a filter screen to rotate, after the filter screen rotates by 90 degrees, cement with large granularity on the filter screen falls into the material falling port and falls into the cavity through the material falling port, and therefore the cement on the filter screen is convenient to clean away.

Description

technical field [0001] The invention relates to the field of cement processing, in particular to a cement negative pressure sieve analyzer which is convenient for heat dissipation. Background technique [0002] The cement fineness negative pressure sieve analyzer is used to test the fineness of Portland cement, ordinary Portland cement, slag Portland cement, fly ash Portland cement, composite Portland cement, and cement fineness negative pressure. When the sieve analyzer uses air flow as the power medium for sieving, the whole system maintains a negative pressure state, and the fine powder material to be tested in the screen is in a flow state under the action of the air flow ejected by the rotating jet nozzle, and together with the air flow Movement, in which the fine particles with a particle size smaller than the screen aperture are driven by the airflow to be pumped away through the screen, while the coarse particles with a particle size larger than the screen aperture r...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a cement negative pressure sieve analyzer that is convenient for heat dissipation in order to solve the problem that it is difficult to clean the cement with larger particle size on the analysis sieve and the effect of dredging the analysis sieve is not good.
