[0026] Working principle: Zinc oxide dust removal device is usually used to treat waste gas containing zinc oxide to ensure that the quality of the discharged air meets environmental protection standards. Zinc oxide is an inorganic compound with the chemical formula ZnO. It is an oxide of zinc. Zinc oxide is generally removed by a dust removal device. The dust removal device is provided with an air inlet, an exhaust port and a dust removal box. The air inlet is used to receive the waste gas containing zinc oxide, and the exhaust port is used to discharge the treated clean gas. In the dust removal box, a filtration system is provided. The filtration system includes a bag filter for capturing and collecting zinc oxide particles in the waste gas. A bag filter is provided inside the purification box 3, and an exhaust pipe is provided on the back of the purification box 3. The exhaust pipe The purified gas can be discharged, and the dust suction pipe 4 can mainly receive the waste gas containing zinc oxide. After starting the vacuum pump 2, the waste gas containing zinc oxide can be sucked into the interior of the purification box 3 through the dust suction pipe 4. The waste gas first passes through the filter cylinder 5 and is then guided to the interior of the dust removal box 1. The waste gas is again introduced into the interior of the purification box 3, so that the zinc oxide particles and dust can be filtered and purified, and large particles of impurities will be blocked by the filter net 16. As the use time increases, the amount of large particles of impurities on the surface of the filter net 16 gradually increases, and then the surface area of ​​the filter net 16 becomes smaller. At this time, it will hinder the exhaust gas from being introduced into the interior of the purification box 3, slowing down the exhaust gas. The purification speed is increased. At this time, the rotating rod 18 is manually rotated clockwise to drive the vertical plate 12 to move to a position close to the filter cylinder 5. Under the action of the clamping ring 13, the split cover 15 moves at the same time, and the filter screen 16 gradually fits with the multiple scraper strips 7. The multiple scraper strips 7 will be embedded in the surface of the filter screen 16, so that the impurities blocked on the surface can be pounded out, increasing the ventilation area of ​​the dust collecting cover 14. Then, the area of ​​exhaust gas passage will be increased, thereby accelerating the speed of exhaust gas being guided to the inside of the purification box 3, and then accelerating the speed of dust removal of exhaust gas containing zinc oxide. When the rotating rod 18 is rotated, the threaded rod 10 fixed thereto is driven to rotate at the same time. Due to the movement The outer surface of the movable block 11 fits with the inner wall of the straight plate 9, so during the rotation of the threaded rod 10, the movable block 11 will move left and right, thereby driving the vertical plate 12 and the clamping ring 13 to move, and the clamping ring 13 and one end of the dust collecting cover 14 are fixedly sleeved, thereby driving the dust collecting cover 14 to move at the same time. Since the corrugated circular tube 8 is composed of a combination of foldable corrugated sheets, it will gradually extend and stretch after being subjected to force, thereby not interfering with the left and right movement of the split cover 15. By rotating the two positioning columns 19 in the opposite direction, the two adjacent arc blocks 17 can be separated from each other, so that the dust collecting cover 14 and the split cover 15 can be separated from each other, and the impurities and dust on the surfaces of both can be cleaned.
