Both the first and second housings are equipped with sealed doors, and safety locks are installed on the sealed doors.

[0011] The beneficial effects of this utility model are:

[0012] (1) When the exhaust fan is started, the external air can be drawn into the first housing from the air inlet and discharged to the outside from the air outlet. During the air flow, the pump indirectly transports the liquid between the outer wall of the partition and the inner wall of the second housing to the atomizing nozzle. The atomizing nozzle sprays the liquid into the air. The dust in the air is humidified and aggravated, and then falls onto the first guide block. The plate air filter filters the dust that is still present in the air, avoiding the situation where some dust is not sprayed and is transported to the outside again. Thus, the present invention can effectively remove the dust generated during the mining construction process. Through the coordinated arrangement of a series of structures such as the pump, connecting pipe, plate liquid filter, first liquid outlet pipe, and second liquid outlet pipe, the liquid that falls from the spray will be discharged into the second housing from the first liquid outlet pipe. The plate liquid filter filters the liquid, and the filtered liquid will be indirectly transported to the atomizing nozzle by the pump again and sprayed out. Thus, the present invention adopts water circulation filtration technology, which reduces the consumption of water resources.

[0013] (2) The output shaft of the geared motor of this utility model passes through the surface of the first mounting plate and is connected to the rotating shaft through the coupling. The bottom end of the rotating shaft passes through the bearing on the top of the first housing and is installed in the bearing on the bottom of the first housing. Cams are installed on the upper and lower sides of the outer wall of the rotating shaft. The cams are located inside the first housing, and the outer wall of the cams is in contact with the outer wall of one side of the third U-shaped plate. When the geared motor starts, it will drive the cam to rotate. The rotation of the cam will reciprocate to squeeze the third U-shaped plate. After the third U-shaped plate is reciprocated to squeeze, the plate air filter will vibrate reciprocally. The reciprocating vibration of the plate liquid filter can prevent dust from clogging the plate air filter.

[0014] (3) The second mounting plate of this utility model is provided with ventilation slots, which is conducive to the exhaust fan to exert the maximum exhaust effect. The second mounting plate is fixedly installed by the first U-shaped clamp, and the plate liquid filter screen is installed by the second U-shaped clamp, which facilitates the replacement of parts and reduces labor intensity.

[0015] (4) The bottom of the hollow rectangular plate of this utility model is provided with multiple sets of second branch pipes and atomizing nozzles, which increases the spray area of ​​atomized water and effectively enhances the dust removal effect.

[0016] (5) The plate-type liquid filter screen of this utility model is installed by the second U-shaped card plate, which facilitates the replacement of parts and reduces labor intensity. The first liquid outlet pipe is provided with a third sealing ring, and the two ends of the connecting pipe are provided with a first sealing ring and a second sealing ring to avoid leakage of liquid during pumping and reduce resource waste.

[0033] In use, this utility model comprises a first housing 6 and a second housing 10, with the second housing 10 positioned below the first housing 6. The first housing 6 and the second housing 10 are connected by a first liquid outlet pipe 25, the bottom end of which penetrates the top of the second housing 10 and extends into its interior. The first housing 6 has an air inlet slot 7 on one side and an air outlet slot 12 on the other side, with an exhaust mechanism mounted on the air outlet slot 12.

[0034] The staff moved the utility model to the location where dust removal was needed, connected it to an external power source, and started it. The exhaust fan 30 started, drawing outside air into the first housing 6 through the air inlet 7 and expelling it to the outside through the air outlet 12. During this airflow, the pump 35 indirectly transported the liquid between the outer wall of the partition 34 and the inner wall of the second housing 10 to the atomizing nozzle 22. The atomizing nozzle 22 sprayed the liquid into the air, causing the dust in the air to become humidified and heavier before falling onto the first guide block 24. The plate-type air filter 23 filters out dust in the air, preventing some dust from being sprayed out and being transported to the outside again, thus effectively removing dust generated during mining construction. The sprayed liquid is discharged from the first liquid outlet pipe 25 into the second box 10. The plate-type liquid filter 39 filters the liquid, and the filtered liquid is indirectly transported to the atomizing nozzle 22 by the pump body 35 and sprayed out. This utility model adopts water circulation filtration technology, which reduces water consumption.

[0035] The bottom four corners of the second box 10 are equipped with self-locking casters 11. The front walls of the first box 6 and the second box 10 are equipped with sealing doors 9, and safety locks 8 are installed on the sealing doors 9. A second rainproof louver 13 is installed on one side of the outer wall of the second box 10. A protective cover 2 is installed on the top of the first box 6.

A first sealing ring 5 and a second sealing ring 14 are provided at both ends of the connecting pipe 1.

[0036] The second rainproof louver 13 provides natural ventilation and rain protection to one side of the interior of the second housing 10. Because the end walls of the second mounting plate 31 are connected to the U-shaped groove walls of the first U-shaped clamping plate 33 with gaps, it facilitates maintenance of the exhaust fan 30. Similarly, because the end walls of the plate air filter 23 are connected to the U-shaped groove walls of the third U-shaped clamping plate 40 with gaps, it facilitates disassembly, replacement, or cleaning of the plate air filter 23. The first rainproof louver 3 provides natural ventilation and rain protection to the interior of the protective cover 2. The end walls at both ends of the mesh 39 are connected to the groove walls of the U-shaped groove on the second U-shaped clamping plate 38 with a gap, which facilitates the disassembly, replacement or cleaning of the plate liquid filter mesh 39 by the staff. Through the coordinated arrangement of the geared motor 16, the rotating shaft 32, the cam 28, the spring 43 and other structures, the geared motor 16 will drive the cam 28 to rotate when it starts. The rotation of the cam 28 will reciprocate to squeeze the third U-shaped clamping plate 40. After the third U-shaped clamping plate 40 is subjected to reciprocating compression, the plate air filter mesh 23 will vibrate reciprocally. The reciprocating vibration of the plate liquid filter mesh 39 can prevent dust from clogging the plate air filter mesh 23.
