Description

Technical Field

[0001] The invention relates to the technical field of coating production ventilation, in particular to a ventilation device for a coating production line. Background Art

[0002] Coating production is a coating process, which is usually used to coat a layer of special materials such as lacquer, glue, paint, etc. on the surface of an object. This process can change the appearance, performance or service life of an object, and is widely used in various industries, such as automobile manufacturing, furniture production, architectural decoration, etc. Therefore, in the coating production line, the air quality in the working environment is required to be high, and the floating dust in the air can easily affect the processing quality of coating production.

[0003] The existing ventilation devices have poor self-purification capabilities. In the process of purifying and filtering dust in the air, the dust filtered on the filter surface needs to be cleaned frequently, affecting the normal working efficiency of the workshop. At the same time, the gas flow direction is single. When the external air refluxes, the dust adhered to the filter surface is blown, which easily causes the problem of dust reflux and affects the air quality of the working environment. Therefore, a ventilation device for a coating production line is introduced. Summary of the invention

[0037] Working principle of the present invention:

[0038] First, the air inside and outside the production line is connected through the annular casing 101, and the wind wheel module 3 is started to let the air enter the inside of the annular casing 101 through the air inlet side plate 102. After the air passes through the dust filter plate 201 on the inner wall of the annular casing 101, it is discharged from one side of the air outlet side plate 103. The air is purified and filtered by the activated carbon inside the dust filter plate 201 to prevent harmful gases from causing harm to the workers.

[0039] The driving motor on the movable drum 401 is started to drive the movable drum 401 to rotate. The outer wall of the movable drum 401 contacts one side of the dust filter plate 201, and the dust filter plate 201 deflects, driving the fixed gear 202 to rotate. The fixed gear 202 drives the meshing movable gear ring 203 to rotate. The movable gear ring 203 squeezes the spring 205 through the protrusion 204. The spring 205 is squeezed and rebounded to vibrate the surface of the dust filter plate 201 to clean the dust on the surface of the dust filter plate 201. At the same time, the outer wall of the movable drum 401 is scraped and cleaned by the dust filter plate 201 to avoid the influence of dust accumulation on the device.

[0040] The movable drum 401 is rotated to drive the internal air inlet impeller 301 and the air outlet impeller 303 to rotate, and the air is sucked in from the air inlet side plate 102, and flows to the dust filter plate 201 through the air inlet through hole 402 on the movable drum 401. The gas rotates and flows to between the annular casing 101 and the movable drum 401. Due to the action of centrifugal force, the dust in the air flows outward, and the dust is filtered through the dust filter plate 201. The filtered gas flows out through the air outlet through hole 403. The air outlet impeller 303 continuously rotates to push the purified air to be blown out from the air outlet side plate 103, thereby reducing the content of floating dust in the environment and improving the working environment quality of coating production.

[0041] The dust filter plate 201 cooperates with the movable drum 401 to vibrate and drop the filtered dust particles. The movable drum 401 rotates continuously, and the airflow rotates along the inner wall of the annular casing 101. The rotating plate 105 is deflected by the negative pressure, so that the dust falls into the dust box 104. The dust is processed centrally by disassembling the dust box 104.

[0042] The connection between the air inlet hole 402 and the air outlet hole 403 allows the air to circulate quickly through the dust filter plate 201 for filtration. At the same time, through the cooperation of the air inlet hole 402, the air outlet hole 403 and the movable drum 401, a Tesla valve structure is formed inside the shell 1, which reduces the problem of air backflow and improves the quality of air purification of the device.
