Technical Field
[0001] This utility model relates to the field of coal-related technology, specifically a coal moisture detection device. Background Technology
[0002] Coal is a carbon-rich, solid, combustible organic sedimentary rock mainly formed from plant remains through coalification. It is the most abundant and widely distributed fossil fuel on Earth, playing a vital role in modern industry. Both heavy and light industries require a certain amount of coal. Moisture testing of coal allows for accurate assessment of its moisture content, thus determining its economic value and providing important reference for coal procurement, sales, and use. Moisture testing devices are equipment used to measure the moisture content of substances.
[0003] In existing coal moisture detection devices, the moisture evaporated after heating the coal is not fully absorbed and may remain in the coal, which can easily affect the detection results and cause deviations. Therefore, it is necessary to propose a new coal moisture detection device. Utility Model Content
[0004] The purpose of this invention is to provide a coal moisture detection device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal moisture detection device, comprising a detection box, an electric heating plate installed on one side of the inside of the detection box, first bolts penetrating both sides of the electric heating plate, a sealing ring fixed on one side surface of the detection box, slide rails fixed on both sides of the inside of the detection box, a slider movably connected inside the slide rails, a partition fixed on one side of the slider, a drying box placed above the partition, a motor installed at the lower inside of one side of the detection box, a drive shaft installed at the output end above the motor, a turntable installed above the drive shaft, a plastic box placed above the turntable, and an electronic balance installed on the other side of the inside of the detection box.
[0006] Preferably, the heating plate is threadedly connected to the testing box via a first bolt, and the first bolt is symmetrically arranged about the central axis of the testing box.
[0007] Preferably, the shape of the sealing ring conforms to the shape of one side of the inner surface of the test box, and the outer side of the sealing ring is in contact with one side of the inner surface of the test box.
[0008] Preferably, the partition plate forms a sliding structure with a slider and a slide rail, and the partition plate and the slider are welded together.
[0009] Preferably, a fan is installed at the rear of the testing box, and second bolts pass through both sides of the fan, with a dust cover fixed to one side of the fan.
[0010] Preferably, the fan is threadedly connected to the testing box by a second bolt, and the second bolt is symmetrically arranged about the central axis of the fan.
[0011] Preferably, the turntable forms a rotating structure with the motor via a drive shaft, and the plastic boxes are distributed circumferentially above the turntable.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This coal moisture detection device uses a combination of a slide rail, a slider, a partition, and a drying box. During the use of this device, the drying box is placed on the partition. The drying box can absorb the moisture generated after the coal is heated and remove the moisture from the coal. By using the drying box, the moisture in the coal can be effectively removed, thereby obtaining more accurate detection results. Furthermore, the partition can be directly pulled out of the slide rail by the slider, which facilitates the replacement of the drying box by the staff.
[0014] 2. This coal moisture detection device, through the setting of a fan, a second bolt and a dust cover, allows the fan to be installed into the detection box through the second bolt during the use of the device, which can quickly cool the inside of the detection box, saving the cooling time of the plastic box, and enabling the staff to weigh the coal after removing the moisture more quickly, thus speeding up the coal moisture detection work progress.
[0015] 3. This coal moisture detection device, through the arrangement of a motor, a drive shaft, a turntable, and a plastic box, allows the drive shaft to rotate the turntable when the motor is turned on during use, resulting in more uniform heating of the coal in the plastic box. The presence of multiple plastic boxes allows for the simultaneous testing of multiple coal samples, meaning that more testing tasks can be completed in the same amount of time, thereby significantly improving work efficiency.

[0023] Please see Figure 1 , Figure 3 and Figure 4 A fan 9 is installed at the rear of the testing box 1. The fan 9 is threadedly connected to the testing box 1 by a second bolt 10. The second bolt 10 is symmetrically arranged around the central axis of the fan 9 to facilitate the disassembly and assembly of the fan 9. The second bolt 10 passes through both sides of the fan 9. A dust cover 11 is fixed to one side of the fan 9. A motor 12 is installed at the lower inside one side of the testing box 1. A drive shaft 13 is installed at the output end of the motor 12. A turntable 14 is installed above the drive shaft 13. The turntable 14 forms a rotating structure with the motor 12 through the drive shaft 13.

After heating for a period of time, the moisture in the coal evaporates, and the drying box 8 on the partition 7 absorbs the moisture. The process involves removing moisture from the coal to ensure more accurate test results. Finally, the device door is opened, and the fan 9 is turned on to quickly cool the plastic box 15, saving cooling time. The cooled plastic box 15 is then weighed on the electronic balance 16.
