Technical Field

The invention relates to the field of pass-through windows, in particular to a clean explosion-proof pass-through window.

Background

The transfer window is a matched auxiliary device of a purification system project and is mainly used for transferring small articles between a clean room and an unclean zone or between clean zones of different grades. On one hand, the air lock plays a role of an air lock, and the high pressure in the high-level clean room is not released; on the other hand, the blow-spray sterilization effect is realized in the transfer process, so that the articles entering the clean area are ensured to be clean, and the cross contamination caused by the articles is prevented and reduced. The blowing and showering time can be set according to actual needs, and the optimized blowing and showering sterilization and energy-saving effects are realized. The air purifier is widely applicable to clean rooms and clean workshops in the industries of medicine, health, electronics, chemical engineering, food processing and the like, such as super-clean workshops or air purification engineering systems in the fields of biomedicine, microelectronics, precision machinery, aerospace, scientific research and teaching and the like.

The transfer window is used as an auxiliary device of the clean room and is mainly used for transferring small articles between the clean area and between the non-clean area and the clean area so as to reduce the door opening times of the clean room and reduce the pollution of the clean area to the maximum extent.

When the cleanliness requirement is C level or above, a common mechanical transfer window can not meet the cleanliness requirement, and a self-circulation filter fan is often required to be introduced, which is a very common method in the market, so that the mechanical transfer window has the advantages of convenience in operation, low cost, ideal cleaning effect and the like, and is widely applied. But the method also has a plurality of disadvantages and hidden dangers in special occasions.

Because the traditional transfer window needs to use a self-cleaning fan and other electric control devices, when the fan rotates, the electric control devices are easy to accumulate static electricity when being started and stopped, and electric sparks are released. In some specific areas, such as the areas containing inflammable and explosive dust, the generation of any open fire is strictly prohibited, otherwise, the serious safety accident is caused, and the traditional transfer window is just like a dangerous source in the production field, which is absolutely not allowed to happen. In order to solve the above problems, we focused on the research and improvement in explosion prevention.
