[0022] The working principle of the self-cleaning air circulation ventilation device in this veterinary drug cleanroom will be explained in detail below.

[0023] like Figure 1-5As shown, the device is first installed at the ventilation opening in the veterinary drug cleanroom. The drive motor 42, stepper motor 61, and electrostatic generator 51 are connected to the power control board in the workshop via wires. The dust collection box 72 is placed inside the collection shell 71 and magnetically fixed to the outer surface of the collection shell 71 using magnets 74. During daily operation, the drive motor 42 is started, and the output shaft of the drive motor 42 drives the fan blades 43 to rotate. The high-speed airflow generated by the two fan blades 43 draws dust and other impurities in the workshop into the rectangular frame 1 through the louvers 3. Then, the electrostatic generator 51 is started, and high-voltage DC is applied between the electrode wire 53 and the metal filter plate 54 to form a strong electric field. When the electric field... When the intensity is high enough, the air is ionized, generating a large number of free electrons and ions, forming a corona region. Under the action of the electric field, charged dust particles move towards the positively charged dust collection electrode and are eventually adsorbed on the surface of the metal filter plate 54, further improving the cleanliness of the air circulation ventilation. After a period of use, the stepper motor 61 is started, and the output shaft of the stepper motor 61 drives the lead screw 62 to rotate, causing the moving collars 64 on both sides to move the cleaning plate 65 downward. During the movement, the brush bristles 67 remove the dust particles attached to the surface of the metal filter plate 54. At the same time, the brush bristles 67 scrape off the dust on the surface of the metal filter plate 54, and the adsorbed dust falls into the dust collection box 72 through the dust collection port 710 for collection.
