[0002] A dust protection device for paint production can be a variety of different devices, and its purpose is to control and reduce the generation, diffusion and harm of dust during the paint production process. The following are some examples of possible dust protection devices: bag filters, electrostatic precipitators, wet scrubbers, local exhaust systems, ventilation ducts and fans, explosion protection systems, dust collection systems. When selecting a suitable dust protection device, it is necessary to consider the properties of the dust (such as particle size, density, flammability, etc.), the requirements of the production process, environmental protection regulations, and economic factors, etc. Usually, an effective dust protection plan may require a combination of multiple devices and technologies.

[0004] However, the device still has the following defects:

[0005] When the device is in use, the device uses a vacuum cleaner to remove the dust generated during the stirring of the mixing barrel. However, there is no air inlet arranged inside the device. When the vacuum cleaner sucks air from the mixing barrel for dust removal, the air inside the device decreases, affecting the continuous use of the vacuum cleaner. Therefore, we need to propose a dust protection device for paint production. Content of the Utility Model

[0006] The purpose of the utility model is to provide a dust protection device for paint production, and by arranging an air inlet pipe on the dust suction hood, it is convenient for ventilation inside the dust suction hood, so as to solve the problems put forward in the above background technique.

During stirring, the vibrator 4 and the dust collector 8 are controlled to work through the control panel 9. The vibrator 4 controls the vibration of the air inlet hood 3 to prevent dust from adhering to the inner wall of the air inlet hood 3. The dust collector 8 sucks out the air inside the air inlet hood 3 through the connecting pipe 7;

[0048] When the vacuum cleaner 8 is in use, the air inside the air inlet hood 3 is pumped out, the air pressure inside the air inlet hood 3 decreases, and under the action of the external air pressure, the sealing plate 55 moves downward to release the sealing of the air inlet pipe 51.
