[0017] Beneficial effects of the present invention:

[0018] 1. The present application provides an air filter for environmentally friendly emissions. The air filter assembly is composed of a vertical plate I, a vertical plate II and a filter element. By utilizing the characteristics of the foldable design of the filter element's filter surface, after back-blowing the filter element with high-pressure gas, the vertical plate II is rotated toward the vertical plate I to overlap the filter element's filter surfaces. After back-blowing, dust, particulate matter and other impurities on the outside of the filter element fall to the bottom of the filter element and will not re-attach to the filter element's filter surface, thereby improving the back-blowing effect of the filter element in the air filter assembly and avoiding the problem that dust, particulate matter and other impurities are easily re-attached to the filter element's filter surface when back-blowing the filter element to clean it. This in turn increases the service life of the air filter and eliminates the need for frequent replacement of the filter element.

[0019] 2. The present application provides an environmentally friendly emission air filter, which is designed with two air filter components. When one air filter component is used for backblowing high-pressure gas cleaning, the other air filter component filters the air normally and is not affected. It only reduces the filtration efficiency and avoids the problem of no effective air filtration during the backblowing cleaning stage. It is convenient to use and reduces the rotation angle of the vertical plate II, so that the filter surfaces of the filter element can be normally overlapped after the vertical plate II is rotated.

A motor 12 for driving the two positioning shafts 11 to rotate is respectively installed on the two positioning circular plates 1. The two positioning shafts 11 are movably sleeved through a positioning sleeve 13 so that the rotation of the two positioning shafts 11 does not interfere with each other.

[0040] After one of the air filter components is back-blown and cleaned, the motor 12 drives the vertical plate II 4 in the air filter component to rotate, so that the vertical plate II 4 in the air filter component rotates toward the vertical plate I 3, thereby compressing the filter element 7, so that the filter surfaces on the filter element 7 overlap, and the dust, particulate matter and other impurities on the outside of the filter element 7 after back-blowing fall to the bottom of the filter element 7 and will not re-attach to the filter surface of the filter element 7, and then the motor 12 drives the vertical plate II 4 in the air filter component to rotate in the opposite direction to reset, and the air filtering work is resumed, while the other During this period, an air filter assembly always performs air filtering work normally and is not affected, thereby improving the backblowing effect of the filter element 7 in the air filter assembly and avoiding the problem that impurities such as dust and particulate matter are easily re-attached to the filtering surface of the filter element 7 when the existing air filter is backblown to clean the filter element 7, thereby increasing the service life of the air filter and eliminating the need for frequent replacement of the filter element 7. The air guide branch pipe 8 is close to one side of the vertical plate I3. After the vertical plate II4 is rotated to overlap the filtering surfaces of the filter element 7, the air guide branch pipe 8 is still located between the vertical plate II4 and the vertical plate I3.

[0041] See also Figure 7 and Fig. 9 Sealing strips 15 are provided at the top and bottom of the vertical plate Ⅱ4. The two sealing strips 15 are movably fitted with the two isolation connecting plates 2 on the side away from the vertical plate Ⅱ4. The sealing strips 15 are used to form a seal between the vertical plate Ⅱ4 and the two isolation connecting plates 2 to ensure that the gas only enters and exits through the filter element 7.

The center of the limiting ring shaft 17 and the axis of the positioning shaft 11 are located on the same straight line. Through the support and limiting function of the limiting ring shaft 17, the vertical plate II4 can rotate stably.

[0044] See also Figure 2-Figure 3 , Fig.10 Two sets of limiting devices 18 are installed on the positioning circular plate 1, and the number of each set of limiting devices 18 is not less than two. The limiting device 18 includes a guide shaft 181 movably mounted on the positioning circular plate 1, one end of the guide shaft 181 is fixedly mounted with a limiting shaft 182, and the other end of the guide shaft 181 is fixedly mounted with a limiting block 183.

The two arc-shaped rubber blocks 20 are respectively movably connected with one end of the two filter elements 7 on one side away from the arc-shaped fixing plates 19. Due to the elastic force of the spring 184 and the limiting effect of the limiting block 183, the arc-shaped rubber block 20 can completely cover one end of the filter element 7, thereby forming an effective seal to ensure that the gas only enters and exits through the filtering surface of the filter element 7.

An electromagnet 22 corresponding to the magnetic block 21 is fixedly mounted on the positioning circular plate 1. When the electromagnet 22 is energized, it is magnetically attracted to the magnetic block 21. After the filter surface of the filter element 7 is cleaned by back-blowing high-pressure gas, the electromagnet 22 is energized to generate a magnetic attraction force on the magnetic block 21, so that the magnetic block 21 drives the arc-shaped fixed plate 19 and the arc-shaped rubber block 20 to move and separate from the filter element 7, thereby ensuring that when the vertical plate II 4 rotates, the two ends of the filter element 7 will not be affected by the arc-shaped rubber block 20.
