At this time, the gas can be washed with water, so that the dust in the gas can flow into the treatment tank through the drain pipe. After being filtered by the filter plate, the washed-out dust can be filtered onto the filter plate. When the drive shaft rotates, the meshing transmission of multiple worms and corresponding worm wheels can drive multiple rotating pipes to rotate synchronously. The corresponding two mesh plates can be used to stir the gas, so that more dust in the gas can be washed out, thus purifying the gas.

[0028] 3. In this invention, after the gas is sprayed and rinsed, it can be discharged through the exhaust pipe. When the gas enters the installation pipe, the composite filter element can be used to filter the remaining dust in the gas, so as to ensure that the discharged gas does not contain dust. This allows the gas environment at the construction site to be purified when used.

[0029] In this invention, by starting the drive motor, external gas can be drawn into multiple filter components. After spraying, the dust in the gas can be washed and filtered, so that the discharged gas does not contain dust. Therefore, when used at construction sites, it can purify the air environment at the construction site and has good practicality. Attached Figure Description

[0045] By starting the drive motor 9, the transmission shaft 12 is driven to rotate. At this time, multiple worm gear components can distribute and transmit the power of the transmission shaft 12 to multiple rotating tubes 6.

The worm 17 is fixedly sleeved on the transmission shaft 12, and the worm wheel 18 is fixedly sleeved on the corresponding rotating tube 6. The worm 17 and the worm wheel 18 mesh with each other.

[0047] When the worm 17 rotates with the drive shaft 12, it can drive the rotating tube 6 to rotate under the meshing transmission action of the worm wheel 18, which can facilitate the stirring of gas.

[0048] In this embodiment, as Figure 3 In the process, the air intake assembly includes a power box 10, an intake pipe 11, a blade shaft 13, an air delivery pipe 16, and a bevel gear component.

[0051] When the driving bevel gear 14 rotates with the drive shaft 12, the meshing transmission of the driven bevel gear 15 can drive the blade shaft 13 to rotate.

[0052] In this embodiment, as Figure 6The water supply assembly includes a water pump 26, a mounting bracket 25, a delivery pipe 27, and a distribution box 20. The distribution box 20 is fixedly installed on the top of the treatment box 2. The top ends of multiple inlet pipes 19 extend into the distribution box 20 and are fixedly connected to the bottom inner wall of the distribution box 20. The mounting bracket 25 is fixedly installed on the top of the movable base 1, and the water pump 26 is fixedly installed on the top of the mounting bracket 25. The top end of the delivery pipe 27 is fixedly installed on the rear inner wall of the distribution box 20, and the bottom end of the delivery pipe 27 extends to the rear side of the treatment box 2 and is fixedly connected to the outlet end of the water pump 26. The suction end of the water pump 26 extends into the mounting bracket 25 and is fixedly installed with a suction pipe. The front end of the suction pipe extends into the treatment box 2 and is fixedly connected to the rear bottom inner wall of the treatment box 2.

[0053] By starting the water pump 26, water can be drawn out of the treatment tank 2, and then pumped to the distribution tank 20 through the delivery pipe 27. After passing through multiple water inlet pipes 19, the water can be dispersed and delivered to multiple rotating pipes 6 to achieve spraying and rinsing of the gas.

[0054] In this embodiment, as Figure 7 In the process, the exhaust assembly includes an exhaust pipe 21 and a filter element component. The exhaust pipe 21 is fixedly installed on the left inner wall of the support cover 5 located on the left side. The top end of the exhaust pipe 21 extends to the top of the processing box 2 and is connected to the filter element component.

[0055] The gas, after being processed by multiple filtration components, can be discharged through the exhaust pipe 21, and secondary filtration of the gas can be achieved using the filter element assembly.

[0056] In this embodiment, as Figure 7 In the process, the filter element component includes a threaded part, an installation tube 22 and a composite filter element 28, and the threaded part is connected to the top end of the exhaust pipe 21 and the inner wall of the installation tube 22 respectively, and the composite filter element 28 is fixedly installed in the installation tube 22.

[0060] In this embodiment, when the device is installed at the construction site, the drive motor 9 can be started to drive the transmission shaft 12 to rotate. At this time, under the meshing transmission of the active bevel gear 14 and the driven bevel gear 15, the blade shaft 13 can be driven to rotate. When the blade shaft 13 rotates, it can generate suction, so that the external gas is transported from the air inlet pipe 11 to the power box 10. Then, the gas can be transported to the connecting cover 7 located on the right side by the gas delivery pipe 16. At this time, the gas can be transported through multiple connecting pipes 8, so that the gas passes through multiple rotating pipes 6, thereby facilitating multiple processing of the gas.

[0061] Then, by starting the water pump 26, the water in the treatment tank 2 can be extracted. Then, the water can be transported to the distribution tank 20 through the delivery pipe 27. Then, through multiple water inlet pipes 19, the water can be sprayed into the corresponding rotating pipes 6 through multiple nozzles 23. At this time, the gas can be washed with water, so that the dust in the gas can flow into the treatment tank 2 through the drain pipe 30. After being filtered by the filter plate 3, the washed dust can be filtered on the filter plate 3. When the drive shaft 12 rotates, under the meshing transmission of multiple worms 17 and corresponding worm wheels 18, multiple rotating pipes 6 can be driven to rotate synchronously. The corresponding two mesh plates 24 can be used to stir the gas, so that more dust in the gas can be washed out, thus purifying the gas.

[0062] After the gas is sprayed and rinsed, it can be discharged through the exhaust pipe 21. When the gas enters the installation pipe 22, the composite filter element 28 can be used to filter the remaining dust in the gas, so as to ensure that the discharged gas does not contain dust. This allows the gas environment at the construction site to be purified, which is very practical.
