Description

Technical Field

[0001] The utility model belongs to the technical field of spherical coal molding, in particular to a strength detection device for spherical coal molding. Background Art

[0002] The strength of spherical coal is a problem that has always attracted much attention in the production line of briquette presses, because the quality of briquette is related to the quality and sales of briquette produced by the briquette production line, and is directly related to the value and profit created by the entire briquette production line. Under specified conditions, the performance indicators of briquette coal under various mechanical forces are divided into cold strength, hot strength, dry strength, wet strength, compressive strength, drum strength and drop strength according to the measurement conditions.

[0003] After the production of spherical coal is completed, in order to ensure the quality of the coal balls, it is usually necessary to use a special strength detection instrument to test its strength. In the prior art, Chinese patent CN206470132U discloses a briquette strength tester, including: a compressed air source, an equipment support, a cylinder arranged on the upper part of the equipment support, a sample base arranged on the lower part of the equipment support, and a working pressure gauge connected to the cylinder, wherein the compressed air source is connected to the cylinder, and the sample base is arranged directly below the cylinder. According to the requirements of coal powder molding, the utility model tests the working pressure of the cylinder while pressurizing the briquette, thereby obtaining the pressure when the briquette is broken. The utility model can significantly reduce the detection time of coal powder molding and improve the analysis ability of raw coal samples.

[0004] However, the coal mold strength tester provided in the above technical solution still has many shortcomings in actual use. For example, when conducting strength testing on coal molds, the compression resistance of coal molds is tested by air pressure, which cannot simulate the pressure that coal molds are subjected to when falling from a height. In addition, the compressive strength of coal molds is also related to temperature factors. The device cannot adjust the temperature, which makes the test not detailed and accurate enough.
