[0002] Coal is a solid combustible mineral. After coal mining is completed, the moisture content inside the coal needs to be tested. The amount of moisture directly affects the value of coal, combustion efficiency, transportation and storage, etc. The most common and rapid method for testing coal moisture on the market is generally the heating and drying method, which determines the moisture content based on the mass loss of coal when it is heated.

[0003] The existing Chinese patent application with application publication number CN118050283A discloses a coal moisture detection device, comprising a base, a chassis is fixedly installed on the top of the base, a weighing device is provided at the inner bottom of the chassis, a feeding device is fixedly installed on the upper end of one side of the chassis, a box door is hinged on one side of the chassis, a fixed bracket is fixedly installed on the top of the chassis, a square groove is opened in the middle of the top of the chassis, a telescopic cylinder is fixedly installed in the middle of the fixed bracket, a drying device is fixedly installed at the bottom output end of the telescopic cylinder through the fixed frame and the square groove, and a hot air blower is fixedly installed on the upper end of one side of the chassis away from the feeding device; the invention uses a first motor to drive the lead screw to drive the slider to slide horizontally inside the bottom rail, so that the position of the feeding box toward the chassis can be adjusted, and at this time, the feeding pipe slides inside the circular groove to cause the discharge pipe to move to the top of the storage barrel, and after the feeding is completed, the first motor drives the lead screw to rotate in the reverse direction to cause the slider to reset, and the feeding pipe and the discharge pipe at its end leave the inside of the storage barrel, so that the position of the feeding mechanism and the crushing mechanism can be adjusted flexibly, and it is convenient for fast feeding and use.

[0004] However, the moisture detection device has the following defects when used specifically: 1. When the existing moisture detection device detects the moisture inside the coal, in order to improve the efficiency of coal detection, the coal to be detected needs to be crushed to ensure that the hot air can fully and quickly contact the coal sample. However, when the coal sample is actually heated to remove the moisture inside it, the heating part is generally set at the bottom of the coal. At this time, after the heating of the coal at the bottom is completed, the top coal needs a longer time for heating and dehydration operation, resulting in a longer detection time. At the same time, the heating and dehydration of the coal set in the upper and lower parts is not uniform enough, the detection data fluctuates greatly, and the detection results are not accurate enough; 2. When the existing moisture detection device detects the moisture content inside the coal by heating and drying, the coal is heated in the air for a long time, and the coal sample being tested is easily oxidized and increased, resulting in low measurement results when testing the moisture content of the coal.

At this time, the gas (nitrogen) can be intermittently injected by overlapping or misaligning the gas channel inside the gas delivery component and the gas channel inside the turntable. On the one hand, it ensures that when the coal is dried and tested, the coal sample (after crushing) is not easy to oxidize and increase, thereby improving the accuracy of the test results.
