But existing centrifugal high pressure fan cannot be to air filtration in air draught at present, the particulate matter in air can accumulate
In centrifugal high pressure fan, and cause centrifugal high pressure fan service life reduce the problem of；Therefore, it is unsatisfactory for existing use
Demand.
Utility model content
The purpose of this utility model is to provide a kind of centrifugal high pressure fans, to solve the problems of the prior art.
To achieve the above object, the utility model provides the following technical solutions: a kind of centrifugal high pressure fan, including air inlet
Cover, support base and damping spring, the support base upper surface are equipped with centrifugal high pressure fan ontology, the centrifugal high pressure fan sheet
One side external surface of air intake on body is connect by fastening bolt with connecting plate, and the connecting plate is arranged in air intake cover one end outer wall
On, air intake cover inner wall top and bottom end are mounted on U-shaped card plate, are equipped with filtering between the U-shaped card plate is adjacent two-by-two
Net, and the both ends of filter screen are connect with the U-type groove gap on U-shaped card plate.
Preferably, air inlet is provided on air intake cover other end outer surface.
Preferably, fixation hole is provided on the connecting plate outer surface.
Preferably, the lower surface of the support base is connected by the upper surface of damping spring and pedestal, and damping spring
Both ends are between support base and pedestal by being welded and fixed.
Compared with prior art, the utility model has the beneficial effects that setting of the utility model by air intake cover, air inlet
Filter screen inside cover can filter the air, and can enter centrifugal high pressure fan ontology to avoid the particulate matter in air
It is interior, thus the utility model solve existing centrifugal high pressure fan cannot particle to air filtration, in air in air draught
Object can accumulate in centrifugal high pressure fan, and cause centrifugal high pressure fan service life reduce the problem of；Pass through U-shaped card plate
Setting, facilitates the installation and removal of filter screen, to facilitate the replacement or cleaning of filter screen, of simple structure and strong practicability.
