[0016] The beneficial technical effects of this utility model are as follows: According to the coal preparation dust removal electromechanical equipment of this utility model, through the setting of the dust washing box and the dust removal box, this device first absorbs coal dust with water, and then physically intercepts it through the dust removal bag, which can perform two-stage dust removal and has a higher dust removal efficiency. During use, coal dust enters the dust washing box through the main air inlet pipe and flows upward. At this time, the annular pipe sprays water downward through the nozzle to contact the coal dust, bringing the coal dust and other particles into the bottom of the dust washing box. The airflow after being absorbed by water rises, passes through the dehumidification net to remove water, and is then introduced into the dust removal box by the fan. After being filtered by the dust removal bag, the clean air is discharged through the exhaust pipe. By setting up the fan, the airflow can agitate the dust removal bag, thereby causing the dust attached to the dust removal bag to fall off, reducing clogging and improving filtration efficiency.

[0025] like Figures 1-6 As shown, the coal preparation dust removal electromechanical equipment provided in this embodiment includes a dust washing box 1 and a dust removal box 2. A fan 3 is provided between the dust washing box 1 and the dust removal box 2. The air inlet end of the fan 3 is connected to the top of the dust washing box 1 through an air inlet pipe 4. The output end of the fan 3 is connected to an air outlet pipe 5 located on one side of the dust removal box 2. An air inlet main pipe 6 is fixedly connected to the middle of the dust washing box 1. An annular pipe 7 located above the air inlet main pipe 6 is installed in the middle of the dust washing box 1. Several nozzles 8 are evenly provided at the bottom of the annular pipe 7. A dehumidifying screen 9 located above the annular pipe 7 is installed in the middle of the dust washing box 1. An intermediate plate 10 is fixedly connected to the middle of the dust removal box 2. Several dust removal bags 11 are connected to the bottom of the intermediate plate 10. An exhaust pipe 12 is connected to the top of the dust removal box 2. By setting up dust washing box 1 and dust removal box 2, this device first absorbs coal dust with water, and then physically intercepts it through dust removal bags 11, which can perform two-stage dust removal and has higher dust removal efficiency. During use, coal dust enters dust washing box 1 through the main air inlet pipe 6 and flows upward. At this time, the annular pipe 7 sprays water downward through the nozzle 8 to contact the coal dust, bringing the coal dust and other particles into the bottom of dust washing box 1. The airflow after being absorbed by water rises, passes through the dehumidifying net 9 to remove water, and is then introduced into dust removal box 2 by fan 3. After being filtered by dust removal bags 11, the clean air is discharged through exhaust pipe 12. By setting up fan 3, the airflow blown out can disturb the dust removal bags 11, thereby causing the dust attached to the dust removal bags 11 to fall off, reducing clogging and improving filtration efficiency.
[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the main air intake pipe 6 is an L-shaped pipe. A conical shroud 13 is provided on the top of the end of the main air intake pipe 6 located inside the dust washing box 1, and a flange 14 is connected to the end of the main air intake pipe 6 located outside the dust washing box 1. The conical shroud 13 is provided to prevent sprayed water from entering the main air intake pipe 6, and the flange 14 is provided to facilitate connection with the dust discharge pipe of the coal preparation machine.
[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a gas collecting hood 15 is fixedly connected to the middle of the dust collection box 1, located between the main air inlet pipe 6 and the annular pipe 7. A through hole 16 is provided in the middle of the gas collecting hood 15, and several through grooves 17 are provided between the edge of the gas collecting hood 15 and the inner wall of the dust collection box 1. By setting up the gas collecting hood 15 and the through hole 16, the airflow can converge and rise in the middle, thereby fully contacting the water and improving dust removal efficiency; by setting up the through grooves 17, water will not accumulate on the gas collecting hood 15.
[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a trough 18 is provided at the bottom of the dust collection box 1. A motor 19 is installed at the bottom of the dust collection box 1, and a scraper 20 located inside the dust collection box 1 is connected to the output shaft of the motor 19. A funnel 21 located below the trough 18 is fixedly connected to the bottom of the dust collection box 1. A drain pipe 22 is connected to the bottom of the funnel 21, and a valve is installed on the drain pipe 22. By setting up the trough 18, motor 19, and scraper 20, the motor 19 drives the scraper 20 to rotate, which can scrape the deposited coal sludge into the funnel 21 and discharge it through the drain pipe 22, thereby achieving a more thorough cleaning.
[0029] In this embodiment, as Figure 1 and Figure 2 As shown, a dust removal pipe 23 is fixedly connected to the bottom of one side of the dust collection box 2. A slot is provided at the top of the dust removal pipe 23, and an insert plate 24 is installed inside the slot. A handle is connected to the top of the insert plate 24. An electric telescopic rod 25 is installed at the end of the dust collection box 2 furthest from the dust removal pipe 23, and a push plate 26 is connected to the output end of the electric telescopic rod 25. By setting up the dust removal pipe 23, insert plate 24, electric telescopic rod 25, and push plate 26, after collecting a large amount of dust, opening the insert plate 24 allows the electric telescopic rod 25 to drive the push plate 26 to discharge the dust through the dust removal pipe 23.
[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, a water inlet pipe 701 is fixedly connected to the middle of the annular pipe 7. By setting the water inlet pipe 701, it is possible to connect to tap water or a water pump.
[0031] In this embodiment, as Figures 1-6As shown in the figure, the working process of the coal preparation dust removal electromechanical equipment provided in this embodiment is as follows:
[0032] Step 1: Connect the main air inlet pipe 6 to the dust discharge pipe of the coal preparation machine, connect the water inlet pipe 701 to tap water or a water pump, and start the blower 3;
[0033] Step 2: Coal dust enters the dust washing box 1 through the main air inlet pipe 6, is collected by the gas collection hood 15, and then rises through the through hole 16. At this time, the annular pipe 7 sprays water downward through the nozzle 8 to contact the coal dust, bringing the coal dust and other materials into the bottom of the dust washing box 1. When sewage needs to be discharged, the valve on the sewage pipe 22 is opened, and the motor 19 is started to drive the scraper 20 to rotate, which can scrape the deposited coal sludge into the funnel 21 and discharge it through the sewage pipe 22.
[0034] Step 3: After being absorbed by water, the airflow rises and passes through the dehumidifying net 9 to remove water. It is then introduced into the dust collection box 2 by the fan 3. After being filtered by the dust collection bag 11, the clean air is discharged through the exhaust pipe 12. When cleaning is required, open the insert plate 24 and start the electric telescopic rod 25 to drive the push plate 26 to discharge the dust through the impurity removal pipe 23.
