Simple tool for detecting strength of coal briquettes

Abstract

The invention provides a simple tool for detecting the strength of coal briquettes. The simple tool comprises a support and a full-sealed water tank, a threaded sleeve is vertically installed on the support, a lead screw installed in the threaded sleeve in a threaded fit mode penetrates through the threaded sleeve, and the full-sealed water tank comprises a tank body with an opening in the upper portion and a leather cover buckled on the opening in the upper portion of the tank body; the tank body is communicated with a water pipe, a pressure gauge is installed at the end, exposed out of the tank body, of the water pipe, a horizontal base plate is arranged on the leather cover, the full-sealed water tank and the water pipe are filled with water, and coal briquettes are placed on the horizontal base plate during work. According to the invention, the coal briquettes are pressed on the full-sealed water tank, the pressure borne by the coal briquettes is converted into the water pressure in the full-sealed water tank in real time, and then the pressure gauge is used for monitoring the change of the water pressure in the full-sealed water tank, so that the indirect measurement of the compressive strength of the coal briquettes is realized, and the maximum value of the pressure gauge (the value monitored by the pressure gauge when the coal briquettes are about to break) can be used for representing the compressive strength of the coal briquettes.

Description

technical field [0001] The invention relates to a briquette detection device, in particular to a simple tool for detecting the strength of briquettes. Background technique [0002] The coal ball is shaped like a ginkgo fruit and as big as a walnut. It is extruded by two relatively rotating rollers with hemispherical dimples on the surface. After the briquettes are formed, the quality of the briquettes needs to be evaluated. The compressive strength of the briquettes is the most important performance index and must-check item to measure the quality of the briquettes. Existing briquette compressive strength measurement, there is a special briquette testing machine, because this kind of special briquette testing machine needs to be used in conjunction with a computer, the cost is high, it is not suitable for the use of small factories or some retail investors. Contents of the invention [0003] The purpose of the present invention is to provide a simple tool for testing the ...
