Description

Technical Field

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

[0002] With rapid industrialization and accelerating urbanization, air pollution has become increasingly severe. Pollutants from various industrial emissions, vehicle exhaust, and construction dust are constantly released into the atmosphere, leading to increased concentrations of particulate matter and harmful gases. This not only severely damages the ecological environment, causing environmental disasters such as smog and acid rain, but also poses a significant threat to human health, causing respiratory and cardiovascular diseases. In the field of air pollution control, air filtration devices, as an effective pollution control method, are widely used in various scenarios such as industrial production, environmental monitoring, and indoor air purification. Their core function is to intercept and separate particulate matter, dust, and other pollutants in the atmosphere through specific filter media, thereby achieving the purpose of purifying the air.

[0003] However, traditional air filtration devices have many limitations in practical applications. On the one hand, most traditional filtration devices adopt a fixed filtration structure, and air can only be filtered through a fixed area of ​​the filter medium. As the filtration process continues, a large amount of pollutants will quickly accumulate in the filter medium in that area, leading to local blockage, a sharp increase in airflow resistance, and a significant reduction in filtration efficiency. This not only increases the energy consumption of the equipment, but also makes it difficult for the filtration device to play a continuous and stable filtration role, and cannot meet the needs of long-term high-efficiency filtration.

[0004] On the other hand, due to the lack of an effective cleaning mechanism, pollutants accumulated on the surface of the filter media are difficult to remove in a timely manner during the filtration process of traditional filtration devices. As time goes by, pollutants continue to accumulate, which will not only further aggravate the clogging of the filter media, but also seriously affect the effectiveness of air pollution prevention and control.

[0005] Therefore, it is necessary to design an air filtration device for atmospheric pollution control. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an air filtration device for air pollution control.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An air filtration device for air pollution control includes a base, an upper part of which is fixedly connected to a housing. An air intake channel is provided inside the housing. An air intake hood communicating with the air intake channel is provided on the upper part of the side wall of the housing. A filter cylinder is provided inside the housing. One end of the filter cylinder is connected to a vent pipe communicating with the inside of the filter cylinder. The end of the vent pipe away from the filter cylinder extends through the housing and is connected to a suction mechanism. A rotating column is fixed to the other end of the filter cylinder. The end of the rotating column away from the filter cylinder extends through the housing. A rotating mechanism connected to the rotating column is provided on the outer wall of the housing. A cleaning mechanism located on one side of the filter cylinder is provided inside the housing. A linkage mechanism connected to the cleaning mechanism and the rotating mechanism is provided on the outer wall of the housing.

[0010] As a further improvement of the present invention, the cleaning mechanism includes a striking plate disposed inside the housing. The side wall of the striking plate is provided with striking protrusions that contact the side wall of the filter screen cylinder. The inner walls of opposite sides of the housing are provided with mounting grooves. The two ends of the striking plate are respectively located inside the two mounting grooves. The two mounting grooves are each provided with a guide rod. The guide rod passes through the striking plate and is slidably connected to the striking plate. Both ends of the guide rod are fixedly connected to the inner wall of the mounting groove. A spring is fitted on the guide rod. One end of the spring is connected to the striking plate, and the other end of the spring is connected to the inner wall of the mounting groove. A movable rod is fixed on the side wall of the striking plate. The movable rod passes through the housing and is fixed with a movable frame. The movable rod is slidably connected to the housing. A stop block is fixed on the inner side wall of the movable frame.

[0011] As a further improvement of the present invention, the linkage mechanism includes two bearing seats fixedly connected to the outer wall of the housing, and the same rotating shaft is rotatably mounted on the two bearing seats. A second synchronous pulley is fixedly sleeved at the end of the rotating shaft, and a first synchronous pulley is fixedly sleeved on the side wall of the rotating column. The first synchronous pulley and the second synchronous pulley are sleeved together by a synchronous belt. A cam is fixedly sleeved in the middle of the rotating shaft. The cam is located inside the movable frame and cooperates with the abutment block.

[0012] As a further improvement of the present invention, the collection mechanism includes a collection box, and a pull-out groove that mates with the collection box is provided through the side wall of the housing.

[0016] The beneficial effects of this invention are: By incorporating a filter cylinder, a suction mechanism, and a rotation mechanism, the suction mechanism creates negative pressure on the surface of the filter cylinder, drawing in atmospheric air through the air inlet hood and air inlet channel. The filter cylinder then filters and removes dust from the air, achieving automatic filtration and purification. The rotation mechanism drives the filter cylinder to rotate, allowing it to filter at different positions in turn, reducing the risk of clogging and effectively maintaining good filtration performance.

[0017] By incorporating a cleaning mechanism, the surface of the filter cylinder can be cleaned, preventing clogging and effectively maintaining good filtration performance, thus improving the filtration effect on atmospheric air.

[0018] By setting up a collection mechanism, the dust that the cleaning mechanism removes from the surface of the filter cylinder can be collected, which facilitates subsequent dust treatment.

[0019] This invention can utilize different positions of the filter cylinder for filtration in turn, and can automatically clean the filter cylinder, reducing the risk of clogging and effectively maintaining good filtration performance. Attached Figure Description

[0024] In this invention, the suction mechanism includes a suction fan 9 installed on the outer wall of the housing 3.

[0025] The rotating mechanism includes a motor 18 mounted on the outer wall of the housing 3. The output shaft of the motor 18 is fixedly connected to a first gear 19. A second gear 20 is fixedly sleeved on the side wall of the rotating column 21. The second gear 20 meshes with the first gear 19.

[0026] The cleaning mechanism includes a striking plate 31 installed inside the housing 3.

When the rotating shaft 26 rotates, it can drive the cam 27 to rotate. When the cam 27 rotates, it can intermittently squeeze the abutment block 29, thereby causing the movable frame 28 to move. Using the movable frame 28 and the movable rod 30, it drives the striking plate 31 to move. With the help of the spring 33, the striking plate 31 can intermittently move quickly toward the filter cylinder 16, thereby driving the striking protrusion 34 to strike the filter cylinder 16, thereby causing the surface of the filter cylinder 16 to vibrate. The vibration can cause the dust on the surface of the filter cylinder 16 to fall off the filter cylinder 16, realizing the automatic cleaning of the filter cylinder 16.
