[0002] Dust workshops are filled with a large amount of dust particles. Workers are in this working environment for a long time.

When the dust-containing air rushes into the inertial collision filtration zone at high speed, a sharply turned airflow is formed under the guidance of the upper guide plate, the first inertial collision mechanism and the second inertial collision mechanism.

By providing a cleaning device, the filter area can be cleaned without disassembling the equipment. When the equipment is shut down for maintenance and the liquid in the water tank needs to be replaced, the vacuum mechanism is first turned on, and the vacuum pump sucks air and discharges it from the dust outlet pipe to the water tank, stirring the water flow to form turbulence, which can re-suspend some of the dust attached to the wall of the water tank, and then open the valve of the drain pipe, so that the suspended dust is discharged along with the water flow, thereby improving the self-cleaning ability of the water tank, and stirring the water flow can also prevent dust from gathering and settling at the drain outlet, thereby ensuring smooth discharge of sewage and avoiding blockage of the drainage pipe. After the drainage is completed, liquid needs to be added to the water tank. The clean liquid in the water tank is sprayed onto the upper guide plate through the liquid replenishment spray head. The upper guide plate blocks the liquid and guides the liquid to fall into the water tank, so that the upper guide plate can be cleaned while replenishing the liquid.

[0027] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-Figure 3As shown, in this embodiment, a multiple air purification device for a dust workshop includes an air inlet box 1, a purification box 2 and an air outlet box 3 arranged in sequence from front to back; the purification box 2 is provided with an inertial collision filter area 21 and a filter filter area 22 located at the rear side of the inertial collision filter area 21, and a water tank 211 is provided at the bottom of the inertial collision filter area 21. The filter filter area 22 includes a first filter 221, a second filter 222 and a cleaning device; the cleaning device includes a movable cleaning brush mechanism 223 and a dust suction mechanism 224, and the The mobile cleaning brush mechanism 223 is arranged between the first filter 221 and the second filter 222. The mobile cleaning brush mechanism 223 can move in the up and down directions and contact the surfaces of the first filter 221 and the second filter 222. The dust suction mechanism 224 includes a dust suction pipe 2241, a dust suction pump 2242 and a dust outlet pipe 2243. The opening of the dust suction pipe 2241 extends into the bottom between the first filter 221 and the second filter 222 and the opening faces upward. The dust outlet pipe 2243 extends below the liquid surface of the water tank 211.

[0029] In this embodiment, the inertial collision filtration area 21 includes an inertial collision device and an upper guide plate 213, the inertial collision device includes a first driving element 214, a first transmission assembly 215, a first inertial collision mechanism 216 and a second inertial collision mechanism 217, the first inertial collision mechanism 216 and the second inertial collision mechanism 217 each include a first rotating shaft, a second rotating shaft and a belt, the belt is sleeved on the first rotating shaft and the second rotating shaft, the first rotating shaft is located in the middle of the purification box 2, the second rotating shaft is located below the liquid surface of the water tank 211, the first driving element can drive the two first rotating shafts to rotate through the first transmission assembly 215, so that the two belts rotate on the corresponding first rotating shaft and the second rotating shaft respectively; the upper guide plate 213 is located at the upper part of the purification box 2, and the bottom end of the upper guide plate 213 extends between the first inertial collision mechanism 216 and the second inertial collision mechanism 217. The first driving element 214 can be a motor, and the first transmission assembly 215 can be belt driven, chain driven or gear driven.

[0030] The air intake box 1, the purification box 2 and the air outlet box 3 are divided into three modules for easy assembly, disassembly and maintenance. The dust-containing air passes through the air intake box 1, the inertial collision filter area 21, the filter filter area 22 and the air outlet box 3 in sequence, which can form multiple air purification.

[0031] Since the two belts rotate on the corresponding first and second rotating shafts respectively, and both belts are partially immersed in the water tank 211, the surfaces of the two belts are wet. When the dust-containing air rushes into the inertial collision filtration area 21 at high speed, a sharply turned airflow is formed under the guidance of the upper guide plate 213, the first inertial collision mechanism 216 and the second inertial collision mechanism 217. Part of the dust hits the belt due to inertia and is adsorbed on the wet surface. The belt rotation will also cause this part of the dust adsorbed on the belt surface to enter the water tank 211. Part of the dust hits the liquid surface of the water tank 211 due to the guiding effect of the upper guide plate 213 and inertia, and is directly absorbed by the water in the water tank 211. Therefore, the inertial collision filtration area 21 can remove part of the dust and reduce the subsequent purification burden.

[0032] The filter holes of the second filter 222 are smaller than the filter holes of the first filter 221. When the air passing through the inertial collision filter area 21 passes through the filter filter area 22, the filter filter area 22 can perform double filtration on the air through the first filter 221 and the second filter 222 to ensure that the air flowing to the air outlet box 3 is clean.

[0033] When the equipment is shut down for maintenance and the first filter 221 and the second filter 222 need to be cleaned, the dust on the surface of the filter is brushed off by moving the cleaning brush mechanism 223, and the dust suction mechanism 224 forms a negative pressure to suck air, and the brushed dust is sucked and discharged into the water tank 211 to prevent the brushed dust from flying again. By setting up a cleaning device, the filter area can be cleaned without disassembling the equipment.

[0035] When the equipment is shut down for maintenance and the liquid in the water tank 211 needs to be replaced, the dust suction mechanism 224 is first turned on, and the dust suction pump 2242 sucks air and discharges it from the dust outlet pipe to the water tank 211, stirring the water flow to form turbulence, which can re-suspend some of the dust attached to the wall of the water tank 211, and then open the valve of the drain pipe 212, and the suspended dust is discharged along with the water flow, improving the self-cleaning ability of the water tank 211. The stirring of the water flow can also prevent dust from gathering and settling at the drain port, ensuring smooth discharge of sewage and avoiding clogging of the drainage pipe. The dust outlet pipe 2243 is inserted obliquely below the liquid surface of the water tank 211 to further enhance the stirring effect of the water flow.

[0040] After the drainage is completed, liquid needs to be added to the water tank 211. The clean liquid in the water tank 231 is sprayed onto the upper guide plate 213 through the liquid replenishment spray head 233. The upper guide plate 213 blocks the liquid and guides the liquid to fall into the water tank 211, so that the upper guide plate 213 can be cleaned while replenishing the liquid.

[0041] The water tank 211 has the functions of cleaning the belts of the first inertial collision mechanism 216 and the second inertial collision mechanism 217, directly absorbing dust caused by inertial collision with the liquid surface, preventing the dust from flying again due to the dust suction mechanism 224, and receiving the liquid from the liquid replenishment spray head 233 to clean the upper guide plate 213.

The left and right ends of the sliding rod 2234 are respectively provided with a connecting structure that slides with the guide rail. The lead screw is driven to rotate by the second driving element 2231, so that the sliding rod 2234 slides up and down along the lead screw. During the sliding process, the two brushes 2235 on both sides of the sliding rod 2234 respectively contact the surfaces of the first filter screen 221 and the second filter screen 222 to brush off the surface dust.
