Description

Technical Field

[0001] This invention relates to the field of fresh air handling unit technology, and in particular to a fresh air handling unit for clean air conditioning in hospitals. Background Technology

[0002] Hospital clean air conditioning systems typically consist of return air handling units, fresh air units, and exhaust air units. The fresh air units handle the entire wet load of the clean space, while the return air handling units operate in a dry condition.

[0003] When existing hospital cleanroom air conditioning fresh air units are in use, hospital air conditioning usually adopts wet cleaning. During the humidification process, a large amount of water vapor is easily deposited on the filter screen, affecting its filtration effect and reducing air circulation. In addition, the filter screen in the fresh air collection box of the hospital must be maintained and cleaned regularly, and the cleaning cycle of the primary and secondary filters is relatively short. Since the filter screen removal operation is relatively troublesome, the maintenance efficiency is greatly reduced. Summary of the Invention

[0015] Beneficial effects

[0016] 1. This device is powered by a dual-head motor, which simultaneously drives two swing blocks to rotate. The swing blocks rotate and swing, and the corresponding convex shaft slides into the limiting through hole, which enables the sliding seat to move the floating filter plate up and down. During the rotation and swing of the swing blocks, the floating frame can move the sliding seat and the floating filter plate left and right. The first and second restoring springs rebound and pull, realizing the multi-directional vibration process of the floating filter plate, thereby effectively preventing the humidified mist from depositing on the floating filter plate and ensuring the filtration effect of the floating filter plate.

[0017] 2. This device is powered by a first servo motor. Through the transmission of the scraper and the adjusting screw, the scraper can be driven to slide back and forth along the guide rod. Since the scraper is in contact with the inner wall of the base frame cavity, it can scrape off the scale and impurities attached to the base frame, which saves the trouble of manual collection and treatment. Its structure is simple and easy to use and operate.

[0018] 3. This device is powered by a second servo motor and uses gears and toothed plates for transmission. It can drive the primary plate filter to slide backward along the limit guide rail. Since the second connecting post is connected to the chain, the chain can drive the secondary bag filter during its backward sliding. The first connecting post is also connected to the chain, so the chain can drive the secondary bag filter to slide backward along the limit guide rail. Through mechanical transmission, the primary plate filter and the secondary bag filter are linked together in sequence and slid out in one go, eliminating the trouble of step-by-step operation. Moreover, the primary plate filter and the secondary bag filter are staggered when they are removed, so they will not affect each other's replacement and cleaning operations, making the structure more reasonable.
