Microwave drying oven for coal quality detection

Abstract

The invention discloses a microwave drying oven for coal quality detection, and relates to the technical field of coal quality detection. The microwave drying oven comprises a drying oven body, a control panel and a drying cavity, the drying cavity is formed in the front surface of the drying oven body, the control panel is fixedly mounted on the front surface of the drying oven body in an embedded mode and located on the left side of the drying cavity, a circulating box is fixedly mounted at the top of the inner wall of the drying cavity, an electric adjusting rod is fixedly connected to the bottom of the circulating box, and a heat insulation block is fixedly connected to the bottom of the electric adjusting rod. Through arrangement of a heating cylinder and a heat conduction pipe, heat entering the circulating box is transmitted into the heating cylinder through the heat conduction pipe, meanwhile, when the heat passes through the heat conduction pipe, the temperature of the inner wall of the heat conduction pipe is increased, and an expansion block can be enlarged, so that the angle of a movable clamping plate can be adjusted; and the higher the heat in the circulating box is, the closer the distance between the heating cylinder and dried coal is, so that the use efficiency of heat can be improved.

Description

technical field [0001] The invention relates to the technical field of coal quality detection, in particular to a coal quality detection microwave oven. Background technique [0002] Coal is a combustible black or brown-black sedimentary rock, which usually occurs in the rock strata or veins of coal beds or coal seams. Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, and the sum of the former three is about Occupying more than 95% of organic matter, it is a very important energy source, mainly through combustion to produce electricity or heat energy, and is also an important raw material for metallurgy and chemical industries, used for refining metals, or producing fertilizers and many chemical products, and with the global energy resources coal as a non-renewable resource has always been valued by the governments of various countries. With the acceleration of the mechanization of the coal industry, coal slime, a by-product of the coal mi...

Problems solved by technology

[0005] The present invention provides a coal quality detection microwave drying box, one of the purposes of which is to be able to re-use the heat in the drying box when drying the coal in the drying box, and to solve the problem of drying When the coal is dried by the oven, the heat cannot be recycled; another purpose is to solve the problem that when the coal is dried, the moisture in the coal is liquefied, which causes the water vapor in the oven to The problem that it cannot be collected is to achieve the liquefaction of the water vapor in the drying box, thereby improving the drying efficiency of coal
