Solid sample division device

Abstract

The invention discloses a solid sample division device, comprising an outer barrel, partition plates, receiving troughs, a feeding hopper, a standard screen, a cover plate, a motor, a pulley, a belt groove, a belt, oblique distribution pipes, a feeding valve, a maintenance door, discharge valves, and support legs; the partition plates are radially fixed at the inner bottom of the outer barrel and divide the inner bottom of the outer barrel into a plurality of receiving troughs in equal area, the feeding hopper is vertically and rotationally arranged in the upper center of the outer barrel, the standard screen is fixed to the upper portion of the feeding hopper, the cover plate is horizontally and rotationally arranged at the upper portion of the standard screen, a motor having a vertical spindle is fixed to the outer side of the outer barrel, and the pulley is fixed to the spindle of the motor. Compared with the prior art, the solid sample division device has the advantages that solid samples can be divided quickly and efficiently, division uniformity for the solid samples is improved, sample drifting is effectively avoided, and experimental operations are greatly facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of shrinkage devices, in particular to a solid sample shrinkage device. 【Background technique】 [0002] Dividing is the most critical procedure of sample preparation. The purpose is to reduce the amount of sample. The division of samples can be carried out by mechanical or manual methods. The sampling volume of solid samples in laboratory testing is relatively large, while the actual testing uses The amount of samples is relatively small, so it is particularly important to obtain representative samples for the division of samples. The existing division method is the quartering method, which uses manual division, and the uniformity of division is poor, and powdery samples are easy to float. , resulting in dirty air in the laboratory, which is detrimental to the respiratory health of the experimenters. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the pri...
