Description

Technical Field

[0002] Zinc carbonate has attracted much attention due to its wide applications in industries such as medicine, cosmetics, coatings, rubber and plastics, dyes, ceramics, petroleum, and fertilizers. However, in its production process, especially in key links such as batching, mixing, pressing, sintering, and finished product processing, operations such as raw material transfer, mixing and stirring, and high-temperature sintering are extremely likely to cause dust problems. To effectively reduce the potential threat of dust to the environment and employees' health, zinc carbonate production enterprises generally add high-efficiency dust removal devices in the production workshop, aiming to significantly reduce the dust concentration in the workshop air.

[0003] The existing dust removal device consists of a support plate, a collection box, and a fan. Among them, both the collection box and the fan are firmly installed on the support plate. A filter screen is bolted inside the collection box. One end of the fan is closely connected to the bottom of the collection box and is mutually penetrated. The upper end of the collection box is fixedly installed with a ventilation pipe. In addition, a bracket is fixedly provided on one end surface of the support plate, a dust suction hood is connected to the bracket, and one end of the ventilation pipe is connected to this dust suction hood. During the dust removal operation, after the fan is started, the dust suction hood will generate a strong suction force, thereby sucking the outside air containing dust into the ventilation pipe and further introducing it into the collection box. After these air containing dust passes through the filtering effect of the filter screen, the dust is effectively intercepted, and the purified air continues to be discharged to the outside through the fan, thereby reducing the dust concentration in the air. When the dust removal device operates for a period of time, the filter screen reaches the adsorption saturation state. At this time, the staff needs to open the collection box. Use tools to unscrew the bolts fixing the filter screen, take out the filter screen for cleaning. After cleaning, the staff uses tools again to reinstall the filter screen in the collection box.

[0004] Regarding the above related technology, when cleaning the filter screen, the staff needs to use tools to disassemble the bolts. After cleaning, the staff also needs to use tools to fix the bolts, which is time-consuming and laborious, thus having the defect of low cleaning efficiency of the filter screen. Summary of the Invention

[0005] In order to improve the working efficiency of cleaning the filter screen, the present application provides a dust removal device for a zinc carbonate production workshop.

[0006] The dust removal device for a zinc carbonate production workshop provided by the present application adopts the following technical solutions: A dust removal device for a zinc carbonate production workshop, comprising a support plate, a fan and a collection box.

At the same time, the rotating assembly drives the third diversion pipe to rotate, driving the spray heads to perform circular motion, expanding the spraying range of the spray heads and enhancing the cleaning effect on the filter screen. In addition, the vibration assembly causes the filter screen to vibrate, effectively preventing the blockage of the filter screen during the cleaning process. At the same time, during the process of the vibration assembly driving the filter screen to move upward, the sealing plate releases the blockage of the water flow groove, so that the water and dust on the filter screen flow from the water flow groove to the lower part of the filter screen. After the cleaning is completed, only the water supply needs to be stopped.

[0044] The motor 28 is started. After the motor 28 drives the rotating rod 61 to rotate forward to a set angle, the rotating rod 61 is then rotated reversely. The rotating rod 61 drives the first synchronous wheel 9 to rotate. The first synchronous wheel 9 drives the second synchronous wheel 91 to rotate through the synchronous belt 92. The second synchronous wheel 91 drives the first guide pipe 22 to rotate reciprocally. The first guide pipe 22 drives the second guide pipe 3, the third guide pipe 4 and the nozzle 41 to swing in the collection box 2. In this way, the spraying angle of the nozzle 41 is changed, and the cleaning strength of the filter screen 21 is improved.

[0045] The implementation principle of an air dust removal device for a zinc carbonate production workshop in an embodiment of the present application is as follows: During the process of cleaning the filter screen 21, first, the open end of the first guide pipe 22 located outside the collection box 2 is connected to a water source, and the water supply is started, so that the water flow sequentially passes through the first guide pipe 22, the second guide pipe 3 and enters the third guide pipe 4, and finally is sprayed out by the nozzle 41, directly impacting the surface of the filter screen 21 to achieve cleaning. During this period, the rotating assembly 5 drives the third guide pipe 4 to rotate, and then drives the nozzle 41 to perform a circular motion, effectively expanding the spraying range of the water flow. At the same time, the vibration assembly 6 is activated, prompting the filter screen 21 to vibrate in the vertical direction, effectively preventing blockage. In particular, when the filter screen 21 rises, the sealing plate 212 automatically releases the closure of the water trough 211, allowing the water flow and dust on the filter screen 21 to smoothly flow through the water trough 211 to the lower part. After the cleaning operation is completed, the second sealing plate 291 is opened, and the accumulated water and dust in the collection box 2 are discharged from the miscellaneous outlet 29. There is no need to manually turn the bolts throughout the process, saving time, thereby improving the working efficiency of cleaning the filter screen 21.
