Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a zinc oxide dust removal device. Background Art

[0002] Zinc oxide is an oxide of zinc, which is insoluble in water but soluble in acid and strong alkali. Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints, ointments, adhesives, foods, batteries, flame retardants and other products. Zinc oxide has a large energy band gap and exciton binding energy, high transparency, and excellent room temperature luminescence performance. It is used in liquid crystal displays, thin film transistors, light-emitting diodes and other products in the semiconductor field. In addition, microparticle zinc oxide as a nanomaterial has also begun to play a role in related fields. Zinc oxide will produce a lot of dust during production. If it is not treated, it will cause air pollution. For this reason, a dust removal device will be set up during the production process of zinc oxide to remove the waste gas discharged into the air during the production of zinc oxide.

[0003] For example, the application number is 201920952914.6, a zinc oxide dust removal device, which adopts a design that combines mechanical vibration and pulse airflow as a cleaning method. This structure advantageously extends the service life of the filter bag; this method is most effective when the device is out of use. If the device is in operation, the airflow will change the direction of the exhaust gas blowing toward the filter bag, thereby reducing the wind force passing through the filter bag, which will in turn make the dust removal efficiency of the exhaust gas in the zinc oxide production process lower.

[0004] Therefore, those skilled in the art provide a zinc oxide dust removal device to solve the problems raised in the above background technology. Utility Model Content

Among them, the first fixed plate 2 and the second fixed plate 3 are adapted to the inner diameter of the dust removal chassis 1, so that it can be prevented that during the dust removal treatment of the waste gas in the zinc oxide production process, dust from zinc oxide will pass through the gap between the first fixed plate 2, the second fixed plate 3 and the inner wall of the dust removal chassis 1 and enter the dust cleaning device above the first fixed plate 2 and below the second fixed plate 3, thereby affecting the dust removal effect of the waste gas in the zinc oxide production process.

[0023] like Figures 3 to 5As shown, the dust cleaning device includes a fixed horizontal plate 5 fixedly arranged in the dust removal case 1, a transmission member 6 is rotatably arranged on the fixed horizontal plate 5, a transmission disc 7 is fixedly arranged on the transmission member 6, a connecting rod 8 is fixedly arranged on the transmission disc 7, a first push rod 9 is sleeved on the connecting rod 8, and a second push rod 10 is rotatably connected to the end of the first push rod 9 away from the connecting rod 8. A fixed block 11 is fixedly arranged at the end of the second push rod 10 away from the first push rod 9, a dust scraping block 12 is fixedly arranged on the fixed block 11, and an end surface of the dust scraping block 12 away from the fixed block 11 is attached to the dust removal mesh plate 4. A servo motor 13 is fixedly arranged on the dust removal case 1, and the servo motor 13 corresponds to the transmission member 6 in the dust removal case 1, and the output end of the servo motor 13 is connected to the transmission member 6 on the fixed horizontal plate 5. There are multiple dust removal screens 4 in the dust removal chassis 1, wherein the mesh size of the dust removal screens 4 decreases from left to right. There are multiple transmission disks 7 rotatably connected through transmission members 6 on the fixed cross plate 5, and the transmission members 6 on the multiple transmission disks 7 are connected by belts.

[0024] In this embodiment, when the exhaust gas in the zinc oxide production process is transported to the dust removal box 1, the servo motor 13 is started. The start of the servo motor 13 drives the transmission member 6 connected thereto to rotate, and the rotation of the transmission member 6 drives the transmission disk 7 on the transmission member 6 to rotate. The rotation of the transmission disk 7 drives the connecting rod 8 thereon to rotate. The rotation of the connecting rod 8 will push the first push rod 9 mounted thereon to move up and down. The movement of the first push rod 9 pushes the second push rod 10 to move. The movement of the second push rod 10 drives the scraper block 12 to move on the dust removal mesh plate 4. The movement of the scraper block 12 will clean the dust attached to the dust removal mesh plate 4. The servo motor 13 drives the transmission member 6 to rotate while the transmission members 6 connected to each other by belts all rotate. The rotation of multiple transmission members 6 will drive the scraper blocks 12 on multiple dust removal mesh plates 4 to move up and down, thereby removing dust.

[0025] By setting up the dust cleaning device, the dust attached to the dust removal mesh plate 4 can be cleaned, so that the device can avoid being blown through the dust removal mesh plate 4 from other directions during operation. Not only will the exhaust gas passing through the dust removal mesh plate 4 change direction, thereby reducing the wind force passing through the dust removal mesh plate 4, and further reducing the dust removal efficiency of the exhaust gas in the zinc oxide production process, but the setting of the dust cleaning device also reduces the problem of low dust removal efficiency of the exhaust gas in the zinc oxide production process caused by clogging of the mesh holes of the dust removal mesh plate 4.

Slide blocks 15 are fixedly provided at both ends of the scraper block 12, and the slide blocks 15 at both ends of the scraper block 12 are slidably connected in each group of slide grooves 14.

[0027] Among them, the setting of the slide groove 14 and the slider 15 can reduce the friction between the scraper block 12 and the inner wall of the dust removal box 1, thereby improving the service life of the device. While reducing the friction between the scraper block 12 and the dust removal box 1, the scraper block 12 can slide up and down in the dust removal box 1 more smoothly.

[0030] The working principle of the utility model is:

[0031] First, the exhaust gas in the zinc oxide production process is transported to the dust removal box 1 through the air inlet 16. The exhaust gas transported to the dust removal box 1 will be filtered and dusted through the dust removal screen 4. In the process of filtering the exhaust gas, the dust removal screen 4 starts the servo motor 13. The start of the servo motor 13 drives the transmission member 6 connected thereto to rotate. The rotation of the transmission member 6 drives the transmission disk 7 on the transmission member 6 to rotate. The rotation of the transmission disk 7 drives the connecting rod 8 thereon to rotate. The rotation of the connecting rod 8 drives the first push rod 9 mounted thereon to move up and down. The movement of the first push rod 9 drives the second push rod 10 to move. The movement of the second push rod 10 drives The scraper block 12 moves on the dust removal mesh plate 4. The movement of the scraper block 12 will clean the dust attached to the dust removal mesh plate 4. The servo motor 13 drives the transmission member 6 to rotate while the transmission members 6 connected to each other by belts all rotate. The rotation of multiple transmission members 6 will drive the scraper blocks 12 on multiple dust removal mesh plates 4 to move up and down, thereby removing dust. The exhaust gas passing through the dust removal mesh plate 4 will be discharged from the dust removal chassis 1 through the air outlet 17.
