In addition, according to the different needs and application scenarios of the clean workshop, the blowing ventilation structure may also include other specific designs and measures.

[0003] At present, some blowing ventilation equipment is usually installed on the top of the factory building by bolts, which is convenient for the equipment to extract external air. In order to ensure the normal production of the factory building and the stability and reliability of the production environment, the indoor ambient temperature and relative humidity must be effectively controlled to ensure the stability of product quality and safety and hygiene. However, when the adsorption plate in the equipment needs to be replaced and repaired after long-term use, the staff needs to carry tools to disassemble the equipment and then disassemble the adsorption plate. This operation is complicated and it is not easy to replace and repair the adsorption plate, which reduces the practicality of the equipment. Utility Model Content

This operation is complicated and it is not easy to replace and repair the adsorption plate, which reduces the practicality of the equipment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blowing ventilation structure for a clean workshop, comprising a ventilation tank, on which a limiting device is arranged to realize rapid disassembly and installation;

Then the outside air is processed by the adsorption plate inside the ventilation tank and then enters the workshop to achieve ventilation. This prevents dust in the air from entering the workshop, improves the practicality and efficiency of the equipment, and at the same time improves the quality of the workshop air.
