Briquette coal sample preparation device

Abstract

A briquette sample preparation device, characterized in that it includes a column, an upper panel, a lower panel, a middle panel, a pad, a hollow cylinder, a lower part of the chassis, an upper part of the chassis, a jack, and a jack piston rod; the lower part of the chassis and the upper part of the chassis Consolidation into one body; the inner surface of the hollow cylinder is smooth; the pads can be fully extended into the cylinder and are in close contact with the inner wall of the cylinder; there are four columns in total, the columns penetrate the middle panel, and the two ends are respectively fixed On the upper and lower panels; the jack is placed in the center of the lower panel. The briquette sample preparation device can independently complete sample preparation, is easy to operate, requires less labor, and has a high success rate of sample preparation.

Description

technical field [0001] The invention relates to laboratory equipment, in particular to a briquette sample preparation device. Background technique [0002] When testing the mechanical properties of soft coal, it is necessary to make a large number of molded coal samples. The molded coal has become a commonly used sample in the laboratory. The existing molded coal sample preparation device does not have the function of independent sample preparation. When used in conjunction with a machine, the device has to be transported many times, the operation is cumbersome, time-consuming and laborious, and the success rate of sample preparation is low. The prepared coal samples are often not up to standard and cannot meet the test requirements. Contents of the invention [0003] The invention aims at avoiding the disadvantages of the prior art, and relates to a briquette sample preparation device. [0004] For realizing this purpose, the structure that the present invention adopts i...
