Description

Technical Field

[0001] This utility model belongs to the field of air pollution control technology, and in particular relates to an air filtration device for air pollution control. Background Technology

[0002] Air pollution control refers to treating the atmospheric environment as a whole within a specific area, uniformly planning energy structure, industrial development, and urban construction layout, comprehensively utilizing various pollution control technologies, and making full use of the environment's self-purification capacity to improve air quality. Filtration devices are needed in air pollution control, but existing filtration devices are not ideal in terms of filtration efficiency. After prolonged use, the filter screens are prone to clogging, affecting filtration effectiveness and making them inconvenient for users. A search revealed that patent CN219559031U discloses an air pollution control filtration device, including a base plate, a housing fixedly connected to the top of the base plate, an intake fan connected to one side wall of the housing, and several exhaust holes on the other side wall of the housing. Inside the housing, along the airflow direction, a filtration section and a deodorization section are arranged sequentially. Cleaning sections are located on both sides of the filtration section, and a water storage tank is located at the bottom of the filtration section, fixedly connected to the top of the base plate. A battery is fixedly installed on the top of the base plate near the exhaust holes. The cleaning section, the intake fan, and the battery are electrically connected.

[0003] However, in actual use, the applicant found that the method of cleaning the filter screen by driving the lead screw to rotate by the motor to drive the brush to move up and down could not effectively remove the impurities from the filter screen. Therefore, we propose an air filtration device for atmospheric pollution prevention and control. Utility Model Content

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] An air filtration device for air pollution control includes a base 1. A filter box 3 is fixedly connected to the top of the base 1 via a support column 2. A filter screen 9 is inserted inside the filter box 3. An activated carbon plate 10 is inserted into the filter box 3 above the filter screen 9. A water spray plate 11 is arranged between the filter screen 9 and the activated carbon plate 10. Nozzles are evenly arranged at the bottom of the water spray plate 11. An air inlet pipe 31 is arranged on the front side of the filter box 3, and an air outlet pipe 33 is arranged on the rear side of the filter box 3. A fan 6 is fixedly installed inside the air outlet pipe 33. By installing the fan 6 at the air outlet pipe 33, the fan 6 can be better protected. A sewage hopper 34 is fixedly installed at the bottom of the filter box 3. A sewage branch pipe is arranged at the lower part of the sewage hopper 34, and a sealing cap 341 is threadedly screwed onto the lower end of the sewage branch pipe. A water tank 4 is fixedly connected to the top of the base 1 on the rear side of the filter box 3. A water pump 5 is fixedly installed on the top of the water tank 4. The water inlet is connected to the bottom of the inner side of the water tank 4. The water outlet pipe of the water pump 5 is connected to the water inlet of the spray plate 11 through the water supply pipe 7. The top of the base 1 on the rear side of the water tank 4 is fixedly connected to the battery 8. The rear side of the filter box 3 is fixedly installed with the controller 14. The water pump 5, fan 6, battery 8 and controller 14 are electrically connected through wires. The top of the base 1 on the rear side of the water tank 4 is fixedly connected to the pusher 12. The four corners of the bottom of the base 1 are fixedly installed with the walking wheels 13. By driving the water pump 5, the water inside the water tank 4 is transported to the spray plate 11 and sprayed out through the nozzles at the bottom of the spray plate 11. This can wash away the impurities and dust on the filter screen 9, thereby avoiding the filter screen 9 from being blocked and ensuring the smooth ventilation of the filter screen 9. The sewage generated during the washing process can be collected through the sewage hopper 34, and the sewage in the sewage hopper 34 can be discharged by opening the sealing cover 341.

[0022] The filter box 3 has a take-out window, and a door 32 is provided on the outside of the take-out window. The door 32 can effectively seal the take-out window. The inner side wall of the filter box 3 has symmetrically provided insertion slots 35, and there are two sets of insertion slots 35 arranged vertically. The filter screen 9 and the activated carbon plate 10 are respectively inserted into the two sets of insertion slots 35. The filter screen 9 is located above the air inlet pipe 31, and the activated carbon plate 10 is located below the air outlet pipe 33. By opening the door 32, the filter screen 9 and the activated carbon plate 10 can be taken out from the take-out window, which is convenient for personnel to replace the filter screen 9 and the activated carbon plate 10.

[0023] Working principle: In use, the device can be moved to the desired location, and the fan 6 can be turned on via the controller 14. The fan 6 rotates, creating negative pressure inside the filter box 3. At this time, the air to be filtered enters the filter box 3 through the inlet pipe 31, and impurities in the air are filtered through the filter screen 9. Odors in the air are adsorbed and filtered through the activated carbon plate 10, and finally discharged through the outlet pipe 33, thus achieving air filtration. After a period of time, the fan 6 can be stopped and the water pump 5 can be turned on. The water pump 5 then empties the water from the water tank 4. Water is delivered to the spray plate 11 through the water pipe 7 and sprayed out through the nozzle at the bottom of the spray plate 11, which can automatically wash and clean the filter screen 9. The wastewater generated during the washing process can be collected through the sewage hopper 34. After the filter screen 9 is washed, the water pump 5 is stopped and the fan 6 is turned on again to continue filtering the air. After use, the sealing cover 341 can be unscrewed to discharge the wastewater collected inside the sewage hopper 34. The filter screen 9 and activated carbon plate 10 can be removed or replaced from the inside of the filter box 3 by opening the box door 32.
