Description

Technical Field

[0001] This utility model relates to the field of coal testing technology, and in particular to an auxiliary device for coal quality testing and analysis. Background Technology

[0002] Coal is a traditional energy source formed from the remains of ancient plants over a long period of time. Coal is generally black and is mainly composed of elements such as carbon, hydrogen, and nitrogen. Through the analysis of various physical and chemical properties of coal, including important parameters such as calorific value, ash content, volatile matter, and sulfur content, coal testing is mainly used to assess the quality and suitability of coal.

[0003] Coal quality testing and analysis involves many steps, including reduction, weighing, drying, and cooling. Cooling mainly involves cooling the freshly dried coal. Current cooling methods involve placing the dried coal inside a drying tank and allowing it to cool naturally. Natural cooling takes a long time, which prolongs the entire coal quality testing process.

[0004] Therefore, how to provide an auxiliary device for coal quality testing and analysis is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide an auxiliary device for coal quality testing and analysis. This invention solves the problem in the prior art where the natural cooling of coal after drying results in a long cooling time, thus extending the overall coal quality testing time.

[0006] An auxiliary device for coal quality testing and analysis according to an embodiment of the present invention includes a cooling tank, a placement slot is provided on the side of the cooling tank, and a coal sample placement component is movably placed inside the placement slot; a cooling component is provided on the side of the cooling tank, and an exhaust component is provided on the top of the cooling tank.

[0007] The coal sample placement assembly includes a placement rack, a cover plate, and a positioning assembly. The cover plate is movable on the side of the cooling tank, and one side of the cover plate extends into the interior of the placement channel. The placement rack is fixed on the side of the cover plate located inside the placement channel.

[0008] The coal sample placement assembly also includes a track rod, which is fixed to the inner wall of the cooling tank and corresponds to the placement slot. The placement frame is slidably connected to the surface of the track rod. The positioning assembly includes two magnets with opposite polarities attracting each other. The two sets of magnets are respectively embedded in the side of the cooling tank and the surface of the cover plate.

[0009] The cooling assembly includes a dehumidifier and an exhaust fan. Both the exhaust fan and the dehumidifier are fixed to the side of the cooling tank, with the dehumidifier located directly above the exhaust fan. The output port of the dehumidifier is fixed to the air inlet of the exhaust fan.

[0010] A flow-dividing assembly is provided at the bottom of the inner wall of the cooling tank. The flow-dividing assembly is fixedly connected to the cooling assembly. The flow-dividing assembly includes an air inlet pipe, a central flow-dividing chamber, and a flow-dividing pipe. The air inlet pipe is located at the bottom of the inner wall of the cooling tank. The central flow-dividing chamber is located at the middle of the bottom of the inner wall of the cooling tank. One end of the air inlet pipe is fixed to the surface of the central flow-dividing chamber, and the other end of the air inlet pipe is fixed to the output port of the exhaust fan. The flow-dividing pipe is fixed to the side of the central flow-dividing chamber and is offset from the air inlet pipe. The flow-dividing pipe is located directly below the placement rack.

[0011] The exhaust assembly includes an exhaust port and an exhaust fan. The exhaust port is located at the top of the cooling tank and directly above the central distribution chamber, and the exhaust fan is built into the exhaust port.

[0012] The exhaust assembly also includes a filter screen, which is located at the top of the air intake.

[0013] The interior of the cooling tank is equipped with a partition mesh plate located between the placement rack and the flow distribution assembly.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a coal sample placement component and a cooling component, the coal sample placement component is moved by a pull-out mechanism to place the coal sample. Then, the cooling component provides dehumidified air into the cooling tank to accelerate the gas flow inside the cooling tank while also injecting fresh air. The heated air is then discharged from the top exhaust component, which achieves the effect of accelerating the gas flow inside the cooling tank to speed up the cooling of the coal sample. This solves the problem in the existing technology where natural cooling after coal drying leads to a long cooling time, thus prolonging the overall coal quality testing time.

[0016] By setting up a flow diversion component, the airflow entering the cooling tank is precisely diverted to the area directly below each placement rack. This allows fresh air from the outside to directly contact the coal samples on the placement rack, thereby improving the accuracy of the airflow reaching the coal samples.

The coal sample placement assembly 3 includes a placement frame 6, a cover plate 7, and a positioning component 8. The cover plate 7 is movably located on the side of the cooling tank 1, with one side extending into the interior of the placement slot 2. The placement frame 6 is fixed to the side of the cover plate 7 located inside the placement slot 2. A partition mesh plate 19 is installed inside the cooling tank 1 between the placement frame 6 and the diversion component 13. The coal sample placement assembly 3 also includes a track rod 9, which is fixed to the inner wall of the cooling tank 1 corresponding to the interior of the placement slot 2. The placement frame 6 slides... The positioning assembly 8 is connected to the surface of the track rod 9. It includes two sets of magnets 10 that attract each other. The two sets of magnets 10 are respectively embedded in the side of the cooling tank 1 and the surface of the cover plate 7. When the cover plate 7 is completely closed in the placement channel 2, the two sets of magnets 10 attract each other. During operation, the cover plate 7 is pulled first, causing it to separate the two sets of magnets 10. Then the cover plate 7 moves to move the placement rack 6 out of the cooling tank 1 from the placement channel 2. The coal sample is then placed on the placement rack 6. The placement rack 6 is then placed and inserted into the cooling tank 1 through the placement channel 2. When the cover plate 7 is completely covered in the placement channel 2, the two sets of magnets 10 attract each other.

[0027] The cooling tank 1 is provided with a cooling assembly 4 on its side. The cooling assembly 4 includes a dehumidifier 11 and an exhaust fan 12. The exhaust fan 12 and the dehumidifier 11 are both fixed on the side of the cooling tank 1, and the dehumidifier 11 is located directly above the exhaust fan 12. The output port of the dehumidifier 11 is fixed to the air inlet of the exhaust fan 12. During operation, the exhaust fan 12 draws fresh air from outside into the dehumidifier 11 for dehumidification. The dehumidified air is then sent into the interior of the cooling tank 1 through the exhaust fan 12 to cool the coal sample.

[0028] The top of the cooling tank 1 is provided with an exhaust assembly 5, which includes an exhaust port 17 and an exhaust fan 18. The exhaust port 17 is located on the top of the cooling tank 1 and directly above the central distribution chamber 15. The exhaust fan is built into the exhaust port 17. The exhaust assembly 5 also includes a filter screen, which is located on the top of the air inlet to improve the filtration effect and prevent dust from entering the interior of the cooling tank 1. During operation, fresh air enters the cooling tank 1 and drives the hot airflow upward. The rising hot airflow passes through the exhaust port 17, and the rotation of the exhaust fan 18 drives the hot airflow to be quickly discharged from the exhaust port 17.

[0029] Example 2

[0030] refer to Figure 1-5A flow-dividing assembly 13 is provided at the bottom of the inner wall of the cooling tank 1. The flow-dividing assembly 13 is fixedly connected to the cooling assembly 4. The flow-dividing assembly 13 includes an air inlet pipe 14, a central flow-dividing chamber 15, and a flow-dividing pipe 16. The air inlet pipe 14 is located at the bottom of the inner wall of the cooling tank 1, and the central flow-dividing chamber 15 is located at the middle of the bottom of the inner wall of the cooling tank 1. One end of the air inlet pipe 14 is fixed to the surface of the central flow-dividing chamber 15, and the other end of the air inlet pipe 14 is fixed to the output port of the exhaust fan 12. The flow-dividing pipe 16 is fixed to the side of the central flow-dividing chamber 15 and is connected to the air inlet pipe. The air intake pipe 14 is staggered, and the diversion pipe 16 is located directly below the placement rack 6. During operation, when the exhaust fan 12 sends fresh air into the intake pipe 14, the fresh air is then diverted to the diversion pipe 16 through the central diversion chamber 15. The fresh air is then discharged vertically upward through the air holes on the diversion pipe 16. Since the diversion pipe 16 is located directly below the placement rack 6, the vertically upward fresh air will directly act on the coal sample on the placement rack 6, greatly improving the cooling effect on the coal sample. Then, the heated air is discharged through the exhaust port 17.
