Description

Technical Field

[0001] This utility model relates to a dust treatment device, and more particularly to a coal dust treatment device, belonging to the field of coal mine machinery technology. Background Technology

[0002] In coal processing and usage sites, such as coal preparation plants and boiler rooms, there is a significant amount of dust. To prevent dust from affecting the workshop environment and the health of employees, it is necessary to treat coal dust. Existing technologies, such as the utility model application with application number 202323507929.7, disclose a coal mining spray dust suppression device. To address the problem that current dust suppression devices generally rely on spraying water mist into the air, which is a relatively simple method and has an unsatisfactory dust removal effect, this device is equipped with a mist cannon for spray dust removal and a water washing and adsorption system. When the air pump is working, air mixed with coal dust is drawn into the water tank through the air inlet pipe. Since the air inlet pipe extends below the water surface in the tank, the coal dust is adsorbed in the water as the air rises. The air, now free of coal dust, is discharged through the exhaust pipe, thereby further removing coal dust from the air and improving dust suppression efficiency.

[0003] The above-mentioned applications still have shortcomings:

[0004] After coal powder is drawn into the water, the aqueous solution becomes a suspension. As the amount of coal powder increases, coal powder settles, which causes the liquid level of the device to rise. However, the device cannot regularly remove the sediment during use, affecting the continuous use of the device.

[0005] Therefore, a coal dust treatment device was designed to optimize the above-mentioned problems. Utility Model Content

[0006] The main objective of this invention is to provide a coal dust treatment device to solve the problems mentioned in the background art.

[0037] Example 1

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment proposes a coal dust treatment device, including a water tank 1. An air pump 2 is installed on the top of the water tank 1, and the input end of the air pump 2 is connected to the top of the water tank 1. A telescopic pipe 3 is installed at the middle position on one side of the water tank 1, and a dust suction hood 4 is installed at the top of the telescopic pipe 3. A first turntable 5 is rotatably installed at the bottom of the water tank 1. A receiving groove 6 is evenly opened on the top of the first turntable 5. A cross-shaped partition 7 is fixed on the top of the first turntable 5. The bottom end of the cross-shaped partition 7 separates the adjacent receiving grooves 6, and the side of the cross-shaped partition 7 is in contact with the inner side of the water tank 1. A drive motor 8 is installed at the bottom of the water tank 1, and the output end of the drive motor 8 is fixedly connected to the middle position of the bottom end of the first turntable 5. A sediment discharge mechanism 9 is provided at the bottom of the water tank 1.

[0039] Before use, fill the water tank 1 with water, ensuring the liquid level is below the top of the cross-shaped baffle 7 and above the bottom of the telescopic pipe 3. During use, move the device to the designated location and start the vacuum pump 2 to create negative pressure inside the water tank 1. Gas containing coal dust from the outside enters the water tank 1 through the dust extraction hood 4 and the telescopic pipe 3, first contacting the water. The coal dust then forms a suspension between the cross-shaped baffle 7 and the solution inside the water tank 1. If there is a large amount of coal dust inside the compartment, it will settle inside the receiving tank 6. Then, the drive motor 8 controls the flow of the suspended solids. The first turntable 5 is rotated to connect the solution inside the other compartment with the bottom end of the telescopic tube 3, and the suspension containing coal powder moves to another position in the water tank 1 for sedimentation. After the coal powder in the compartment has settled, the drive motor 8 is started again to connect the bottom of the coal powder compartment after sedimentation with the sediment discharge mechanism 9. The sediment discharge mechanism 9 discharges the coal powder to the outside of the water tank 1. By intermittently controlling the first turntable 5, the coal powder sediment in the water can be removed to ensure the continuous use of the device.

[0040] Example 2

[0041] The solution in Example 1 will be further described below with reference to its specific working method.

[0042] like Figure 5 As shown, in a preferred embodiment, based on the above method, the bottom of the water tank 1 is provided with a carrier plate, and the bottom of the carrier plate is provided with casters. The use of casters makes it easier to push the device and move its position.

[0043] like Figure 5 As shown, in a preferred embodiment, based on the above method, a transparent window is vertically provided on the outside of the water tank 1, and a liquid level line is provided on the transparent window. The liquid level inside the water tank 1 can be observed through the transparent window, and the liquid inside the water tank 1 can be replenished in time after the liquid level reaches the first set position.

[0044] like Figure 3 As shown, in a preferred embodiment, based on the above method, a limiting ring 404 is fixed to the top of the outer side of the water tank 1, and the top end of the telescopic tube 3 is stuck inside the limiting ring 404. During use, the position of the dust hood 4 can be limited by the limiting ring 404, and the dust hood 4 can be used at a fixed point.

[0045] like Figure 3 As shown, in a preferred embodiment, based on the above method, a mounting plate 401 is rotatably mounted on the outer end of the dust hood 4, an electromagnet 402 is mounted on the outer side of the mounting plate 401, and a battery 403 electrically connected to the electromagnet 402 is mounted on the inner side of the mounting plate 401.

[0046] During use, the dust hood 4 can be lifted up and the telescopic tube 3 can be extended. Then, the dust hood 4 can be placed in the dust concentration area, and the electromagnet 402 can be turned on and magnetically attached to the outer shell or metal bracket of the equipment to improve the absorption effect of coal dust.

[0047] like Figure 4 As shown, in a preferred embodiment, based on the above method, the sediment discharge mechanism 9 further includes a collection tank 901, a second turntable 902, a guide trough 903, and a pulley assembly 904. The collection tank 901 is located on the side of the water tank 1 away from the telescopic pipe 3. The second turntable 902 is rotatably mounted inside the water tank 1. The second turntable 902 has a guide trough 903 that cooperates with the receiving tank 6. The number of guide troughs 903 is the same as the number of receiving tanks 6. The pulley assembly 904 is provided between the bottom of the second turntable 902 and the output shaft of the drive motor 8. The first turntable 5 rotates at the same speed as the second turntable 902.

[0048] When the coal powder sediment is discharged, the receiving groove 6 on the first turntable 5 is aligned with the guide groove 903, and the coal powder sediment will enter the interior of the guide groove 903 for storage. As the first turntable 5 rotates, the pulley assembly 904 will simultaneously drive the second turntable 902 to rotate. When the guide groove 903 containing the coal powder sediment on the second turntable 902 enters the top of the collection tank 901, the coal powder sediment will automatically fall into the interior of the collection tank 901 for storage due to its own gravity.

[0049] like Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the receiving tank 6 is funnel-shaped, the sediment discharge mechanism 9 is cylindrical, the diameter of the bottom end of the receiving tank 6 is the same as the diameter of the guide trough 903, the funnel-shaped receiving tank 6 can conveniently collect coal powder sediment, and after the receiving tank 6 is aligned with the guide trough 903, the coal powder can be conveniently moved downward.

[0050] Example 3

[0051] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0052] Before use, fill water tank 1 with water, ensuring the liquid level is below the top of the cross-shaped baffle 7 and above the bottom of the telescopic pipe 3. During use, move the device to the designated location and start the vacuum pump 2 to create negative pressure inside the water tank 1. External gas containing coal dust enters the water tank 1 through the dust extraction hood 4 and the telescopic pipe 3, first contacting the water. The coal dust forms a suspension between the cross-shaped baffle 7 and the solution inside the compartment of the water tank 1. If there is a large amount of coal dust in this compartment, it will settle inside the receiving tank 6. Then, the drive motor 8 controls the first turntable 5 to rotate, connecting the solution in another compartment to the bottom of the telescopic pipe 3. The suspension containing coal dust moves to another location in the water tank 1 for sedimentation. After the coal dust sedimentation in this compartment is complete, the drive motor 8 is used again to rotate the first turntable 5. When the motor 8 is started, it connects the receiving trough 6 at the bottom of the coal powder compartment after sedimentation with the guiding trough 903. The coal powder sediment will enter the interior of the guiding trough 903 for storage. As the first turntable 5 rotates, the pulley assembly 904 will simultaneously drive the second turntable 902 to rotate. When the guiding trough 903 containing the coal powder sediment on the second turntable 902 enters the top of the collecting trough 901, the coal powder sediment will automatically fall into the interior of the collecting trough 901 for storage due to its own gravity. When the receiving trough 6 and the guiding trough 903 are misaligned, the compartment formed by the cross-shaped baffle 7 and the water tank 1 will be sealed again. By intermittently controlling the first turntable 5, the coal powder sediment in the water can be automatically removed to ensure the continuous use of the device.

[0053] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
