Description

Technical Field

[0001] This utility model relates to the field of coal processing technology, specifically to a dust reduction device for a coal washing machine. Background Technology

[0002] As we all know, coal plays an important role in modern industry, whether it is heavy industry or light industry; whether it is energy industry, metallurgical industry, chemical industry, machinery industry, or light textile industry, food industry, and transportation industry. Various industrial sectors consume a certain amount of coal to a certain extent. Therefore, some people call coal the "real food" of industry.

[0003] Common coal washing machines only use simple water spraying to suppress dust. Although this method can suppress dust to a certain extent, the water spraying is uneven, resulting in poor dust suppression in some areas. Moreover, a large amount of water spraying may affect the quality parameters of coal, such as moisture content, which is not conducive to subsequent processing. Therefore, we propose a dust suppression device for coal washing machines. Utility Model Content

The bottoms of the first water outlet hose 63 and the second water outlet hose 67 are fixed on the square water collection plate 68. The middle part of the turntable 66 is provided with a groove for the first water outlet hose 63 and the second water outlet hose 67 to be wound.

[0041] In Embodiment 1, the detachable structure 4 includes a transparent window 41 and detachable bolts 42. The transparent window 41 is located at the front of the dust collection box 3. There are four detachable bolts 42, which are respectively located at the four corners of the transparent window 41. Both the transparent window 41 and the transparent window 42 are made of tempered glass.

[0042] Specifically, by setting transparent viewing windows 2 and 41 on the two side walls of the filter box 2 and the front of the dust collection box 3, it is convenient to monitor the dust collection, dust collection and filtration of the main body 1 in real time, which can improve the dust collection accuracy.

[0043] In Example 2, the number of filter mechanisms 8 is three, and the pore size of the three filter screens 82 decreases sequentially. The materials of the three filter screens 82 are polypropylene, polyester fiber and glass fiber, respectively.

[0044] Specifically, the first filter 82 is made of polypropylene and performs basic filtration on the dust-laden airflow entering the dust suppression device, intercepting some common particle sizes of dust. After the first filter 82 is completed, the airflow enters the second polyester fiber layer for enhanced filtration, which further filters the dust that was not intercepted. Multiple filtration precisions can be selected to further reduce the range of dust particle sizes and improve the overall filtration effect, preparing for high-precision filtration. Finally, the airflow passes through the third filter 82, which is made of glass fiber. This third filter performs high-precision filtration on the fine dust remaining after the first two filtrations, strictly controlling the dust content in the exhaust gas and meeting the high filtration precision requirements of the coal washing machine dust suppression device.

[0045] Working principle:

[0046] First, move the main body 1 of the device to the location where dust suppression of the coal washing machine is required. Support the main body 1 using support blocks and matching anti-slip pads. Start the processor, which activates the first motor 54. The first motor 54 drives the first rotating shaft 55 to rotate. The first rotating shaft 55 drives the two dust extraction fans 56 to begin collecting the smoke, dust, and particulate matter from the coal washing machine through the input hopper 9. During the dust extraction process of the two dust extraction fans 56, the wind speed sensor 53 detects the wind speed inside the dust extraction box 51 in real time. At this time, the smoke, dust, and particulate matter enter the interior of the main body 1. Turn off the first motor 54, and the processor activates the second motor 64 to rotate. The second motor 64 drives the second rotating shaft 65 to rotate. The second rotating shaft 65 drives the bottom-fixed turntable 66 to rotate, simultaneously rotating the square water collection plate 68 at the bottom of the turntable 66. Multiple fixed water outlet pipes 69 and fine mist nozzles 70 rotate, and the second rotating shaft 65 drives the square water collection plate 68 to rotate 90° clockwise from the vertical position to the horizontal position. At the same time, the first water outlet hose 63 and the second water outlet hose 67 are wound around the internal groove of the turntable 66. The processor starts the high-pressure pump. At this time, the water outlet pipes 69 and fine mist nozzles 70 perform dust suppression inside the device body 1. During the dust suppression process, the dust sensor 10 detects the dust, particulate matter and other particles inside the device body 1 in real time. When the concentration of dust, particulate matter and other particles is detected to be lower than 3mg / m3, the processor shuts down the second motor 64. The second motor 64 stops driving and drives the second rotating shaft 65 to rotate 90° counterclockwise from the horizontal position to the vertical position, that is, return to the initial position. The high-pressure pump is shut down, and the water outlet pipes 69 and fine mist nozzles 70 stop the dust suppression operation.

[0047] The smoke and dust sensor 10 detects smoke, dust, and particulate matter inside the main body 1 of the device in real time. When the concentration of smoke, dust, and particulate matter is detected to be higher than 3 mg / m3, the second motor 64 in the dust suppression component 6 is immediately activated. The second motor 64 drives the second rotating shaft 65 to rotate 90° clockwise from a vertical position to a horizontal position, which facilitates the overall dust suppression of the inner cavity of the main body 1. The processor starts the high-pressure pump, and the water outlet pipe 69 at the bottom of the square water collection plate 68 and the fine mist nozzle 70 draw water from the water tank 61 for dust suppression spraying. Because the dust sensor 10, the wind speed sensor 53, and the processor are electrically connected, and with the setting of transparent window 1 41 and transparent window 2, it is convenient to monitor the interior of the main body 1 of the device in real time, resulting in good dust reduction effect. Furthermore, the second motor 64 drives the second rotating shaft 65 to rotate 90° clockwise from the vertical position to the horizontal position, resulting in uniform water spraying and good dust reduction effect. The water spraying is carried out in real time based on the concentration of internal dust, particulate matter, etc., without affecting parameters such as the humidity of the coal, which is beneficial to subsequent processing.

[0048] This concludes the entire workflow.
