Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of moisture detection, and particularly to a mobile device for rapidly measuring the moisture content of coal. Background Art
[0002] Coal is a solid combustible mineral. After coal mining is completed, it is necessary to detect the moisture content inside the coal. The amount of moisture directly affects factors such as the value, combustion efficiency, transportation, and storage of coal. The common and rapid method for detecting the moisture content of coal on the market is generally the heating and drying method, which measures the amount of moisture content based on the mass loss of coal during heating.
[0003] The existing Chinese patent application with the publication number CN118050283A discloses a coal moisture detection device, which includes 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 at the upper end of one side of the chassis. A box door is hinged to 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. The bottom output end of the telescopic cylinder passes through the fixed frame and the square groove and is fixedly installed with a drying device. A hot air blower is fixedly installed at the upper end of the side of the chassis away from the feeding device; in this invention, by using the first motor to drive the lead screw to drive the slider to slide horizontally inside the bottom rail, the position of the feeding box facing the chassis can be adjusted. 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. After feeding, the first motor reversely drives the lead screw to rotate to reset the slider, and the feeding pipe and the discharge pipe at its end leave the inside of the storage barrel, which is convenient for flexibly adjusting the positions of the feeding mechanism and the crushing mechanism and facilitating rapid feeding.
[0004] However, the moisture detection device has the following defects in specific use:
[0005] 1. When the existing moisture detection device detects the moisture inside the coal, in order to improve the detection efficiency of the coal, it is necessary to crush the coal to be detected to ensure that the hot air can fully and quickly contact the coal sample. However, when actually heating the coal sample to remove the moisture inside it, the heating part is generally set at the bottom of the coal. At this time, after heating the coal at the bottom is completed, it takes a long time to heat and remove the water from the coal at the top, resulting in a long detection time. At the same time, the heating and water removal of the coal set in the upper and lower parts are not uniform enough, the detected data fluctuates greatly, and the detection result is not accurate enough;
[0006] 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. This effect is particularly significant when testing coal that has just been mined. Summary of the invention

[0044] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:
[0045] 1. In the device for rapidly and mobilely measuring the moisture content of coal, when detecting the moisture content of coal, the coal to be detected can be crushed by the rotation of two crushing wheels, so that the volume of the coal for drying detection is smaller, and the contact area with the heated drying gas can be increased during subsequent detection, improving the efficiency of detecting the internal moisture content of coal. At the same time, the force driving the crushing wheels to rotate can synchronously drive the coal (after crushing) inside the lower detection frame and the upper detection frame to tumble. Through tumbling, the coal at each position can be fully contacted with the heat medium (generated gas) at the bottom, further improving the uniformity of the coal during heating and drying, and making the detected data more stable and accurate. And the rotational force driving the lower detection frame and the upper detection frame is intermittent, ensuring that there is enough time for contact with the hot gas after each tumbling of the coal;
[0046] 2. In the device for rapidly and mobilely measuring the moisture content of coal, when the lower detection frame and the upper detection frame rotate to drive the coal (after crushing) inside them to tumble, the rotational force driving the lower detection frame to rotate can synchronously drive the gas delivery component to rotate. At this time, by making the gas channel inside the gas delivery component coincide or misalign with the gas channel inside the turntable, intermittent charging of gas (nitrogen) can be achieved. On the one hand, it ensures that the coal sample (after crushing) is not easily oxidized and increased in quantity during the drying detection of coal, improving the accuracy of the detection result. On the other hand, it can reduce the cost of gas (nitrogen) transmission, ensure that the charged gas can be fully mixed with the heated drying gas, and be more uniform when contacting the coal;
[0047] 3. In the device for rapidly and mobilely measuring the moisture content of coal, after the coal is crushed, the crushed coal will first be screened through a screening mesh to ensure that the coal sample meeting the detection standard can be transmitted to its inner bottom along the obliquely arranged discharge pipe, ensuring that when the coal sample is subsequently placed inside the lower detection frame and the upper detection frame for drying, the operation of removing the internal moisture of the smaller coal sample when contacting the hot gas is faster. At the same time, due to the design of the discharge pipe, the staff can conveniently move the crushed coal sample into the lower detection frame and the upper detection frame;
[0048] 4. In the device for rapidly and mobilely measuring the moisture content of coal, when pulverizing the coal to be detected in the next group, the drying detection of the pulverized coal and the operation of charging gas (nitrogen) can be carried out synchronously, ensuring that the operations of pretreatment (pulverization), detection (heating and drying), and detection protection (charging nitrogen) of the coal can be carried out synchronously, effectively improving the efficiency and effect of detecting the moisture content of the coal and ensuring the accuracy of the moisture content detection of the coal.

[0071] See also Figures 1 - 12The mobile device for quickly determining the moisture content of coal comprises a detection box 10, a crushing box 20, an integrated crushing and tumbling mechanism 30 and a gas delivery component 40. The detection box 10 is installed on the top of the base 100. The crushing box 20 is installed on the top of the detection box 10.
