Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device for air purification. Background Technology

[0002] In workshops producing particulate and dusty materials, some dust will be scattered in the air. If the air is not purified and filtered, this dust will enter the respiratory system of the workers and seriously affect their health. Therefore, air purification and filtration devices are needed to purify the air in the workshop.

[0003] Current devices include a purification chamber with a filter inside. Air enters the purification chamber through an air intake hood, is filtered by the filter, and is then discharged from the air outlet.

[0007] Preferably, a collection scraper is fixedly connected to the outer wall of the collection box, the collection scraper is distributed correspondingly to the collection groove, and the collection scraper is attached to the filter screen.

[0008] Preferably, the second agitator blade has a through groove.

[0009] Preferably, the second agitator blade is S-shaped.

[0013] Preferably, a fan is provided on the side of the filter screen near the air outlet hood, and the fan is fixedly connected to the rotating shaft.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model, by setting up a collection box, a collection scraper and other structures, allows particulate impurities to enter the interior of the collection box through the collection groove when air containing particles and dust is drawn in through the exhaust hood, purification cylinder and intake hood, thus achieving the effect of cleaning and collecting particulate impurities.

[0016] 2.

[0023] This utility model provides, for example Figures 1-4The air purification filter device shown includes a purification cylinder 1, one end of which is connected to an air inlet hood 2, and the other end of which is connected to an air outlet hood 3. The air outlet hood 3 is connected to a suction device, which includes a pump and other structures. The suction device draws air containing particles and dust through the air outlet hood 3, the purification cylinder 1, and the air inlet hood 2. The suction device is a common existing technology and will not be described in detail here.

[0024] To filter particulate impurities in the air, a filter screen 4 is fixedly connected inside the purification cylinder 1. The air containing particles and dust is drawn in through the air outlet hood 3, the purification cylinder 1, and the air inlet hood 2. The filter screen 4 filters particulate impurities in the air, reducing wear on the suction equipment and other components.

[0025] Considering that during the filtration of particulate impurities in the air, these impurities can accumulate on the filter screen 4 due to suction, easily causing clogging and affecting suction efficiency, a circular groove is provided on the filter screen 4 to ensure suction efficiency. A rotating shaft 5 is rotatably connected inside the groove. The rotating shaft 5 is concentrically positioned with the filter screen 4. A fan 9 is located on the side of the filter screen 4 closest to the exhaust hood 3, and the fan 9 is fixedly connected to the rotating shaft 5. During suction, the fan 9 drives the rotating shaft 5 to rotate under the action of airflow.

[0026] A collection box 6 is located on the side of the filter screen 4 near the air intake hood 2. The collection box 6 is fixedly connected to the rotating shaft 5, and a collection groove 7 is formed on the side wall of the collection box 6. A collection scraper 8 is fixedly connected to the outer wall of the collection box 6, and the collection scraper 8 is distributed correspondingly to the collection groove 7, with the collection scraper 8 adhering to the filter screen 4. When the rotating shaft 5 rotates, it will drive the collection box 6 to rotate synchronously. The collection scraper 8 and the collection groove 7 are in the windward direction of the rotation direction of the collection box 6. Since the collection scraper 8 is adhering to the filter screen 4, it pushes and scrapes the filter screen 4. Under the pushing and scraping action, particulate impurities enter the interior of the collection box 6 from the collection groove 7, achieving the effect of cleaning and collecting particulate impurities.

[0027] In actual use, the air containing particles and dust is drawn in through the exhaust hood 3, the purification cylinder 1 and the intake hood 2. Under the action of airflow, the fan 9 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the collection box 6 to rotate synchronously. The collection scraper 8 and the collection trough 7 are in the windward direction of the rotation direction of the collection box 6. Since the collection scraper 8 is attached to the filter screen 4, it pushes and scrapes the filter screen 4. Under the pushing and scraping action, the particulate impurities enter the interior of the collection box 6 from the collection trough 7.

[0028] By setting up structures such as the collection box 6 and the collection scraper 8, when air containing particles and dust is drawn through the exhaust hood 3, the purification cylinder 1 and the intake hood 2, the particulate impurities enter the interior of the collection box 6 through the collection groove 7, thereby achieving the effect of cleaning and collecting particulate impurities.

[0029] A second agitator 12 is fixedly connected to the rotating shaft 5, and the second agitator 12 is located at the end of the rotating shaft 5 near the air intake hood 2. When the rotating shaft 5 rotates, it will drive the second agitator 12 to rotate synchronously, agitating the airflow entering the purification cylinder 1 from the air intake hood 2, expanding the distribution range of particles and dust, facilitating uniform filtration by the filter screen 4, and improving the filtration efficiency.

[0030] The second stirring blade 12 has a through groove 13 and is S-shaped to increase the stirring effect and ensure the quality of filtration.

[0031] A purification plate 10 is provided on the side of the purification cylinder 1 near the air outlet hood 3. The purification plate 10 is fixedly connected to the inner wall of the purification cylinder 1. Multiple purification plates 10 are provided. The purification plates 10 can be made of activated carbon material, but are not limited to activated carbon material, and have a purification effect.

[0032] A first stirring blade 11 is fixedly connected to one end of the rotating shaft 5 near the air outlet hood 3. The first stirring blade 11 cooperates with the purification plate 10. The rotating shaft 5 drives the first stirring blade 11 to rotate, stirring the filtered air so that the air can fully contact the purification plate 10 and improve the purification effect.
