Description

Maintenance and cleaning device for ultra-clean workbench

Technical Field

The invention belongs to the technical field of cleaning devices, and in particular relates to a maintenance cleaning device for a clean bench.

Background technique

The clean bench is designed to meet the needs of modern industry, optoelectronics industry, biopharmaceuticals, scientific research and other fields for the cleanliness of local work areas. The principle of the clean bench is that in a specific space, the indoor air is initially filtered by a pre-filter, pressed into a static pressure box by a small centrifugal fan, and then filtered by a high-efficiency air filter. The clean air flow blown out from the air outlet of the high-efficiency air filter has a certain and uniform cross-sectional wind speed, which can remove the original air in the work area and take away dust particles and biological particles to form a sterile and highly clean working environment. Existing clean benches are easily contaminated by external air. In addition, existing air cleaning devices are prone to cleaning dead corners, and dust particles and biological particles are easily floating.

Summary of the invention

The purpose of the present invention is to provide a maintenance and cleaning device for a clean bench, which introduces external air through an air inlet portion, and the incoming air passes through a dust removal portion and undergoes centrifugal motion to achieve dust removal of the air, thereby solving the related problems raised in the background technology.
