Embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figures 1 to 4, a kind of EFU fan filter uints, comprise that one end has the casing 30 that air inlet ring 10, the other end have outlet air surface 20, in casing 30, be provided with intake grill over against the centrifugal blower 40 of air inlet ring 10, outlet air surface 20 places at casing 30 are provided with filter 50, impurity with in filtered air, purifies air.On 30 liang of madial walls of casing, be equipped with the barge board 60 tilting to outlet air surface 20, the air-flow trend that the angle of inclination of barge board 60 can throw away according to centrifugal blower 40 and shape, the size of outlet air surface 20 are set; The barge board 60 of inclination is set, be convenient to by the air-flow blowing out from centrifugal blower 40 take advantage of a situation guiding outlet air surface 20, and reduce the loss of air-flow in casing 30, because traditional fan filter uints does not arrange barge board in casing, air-flow each corner in casing of can flowing through, air loss is larger, such barge board 60 is set in the utility model, can avoid air-flow in the loss at place, the interior dead angle of casing 30, guarantee that blast is stable, the wind blowing out through outlet air surface 20 at the uniform velocity and air quantity large.
Further, at the exhaust outlet place of centrifugal blower 40, be provided with concave surface towards the gradually open form guide plate 70 of this centrifugal blower 40, guide plate 70 is " ︺ " shape, and the flow tendency of the air-flow that guide plate 70 can throw away according to centrifugal blower 40 is carried out water conservancy diversion, thereby reduction crushing, improves efficiency.
The utility model is by arranging the barge board 60 of inclination and the guide plate 70 of " ︺ " shape, the air channel that can restrain gradually after the interior formation of casing 30 is first opened gradually, compare the air channel of traditional straight-through shape, shortened the distance of centrifugal blower 40 with outlet air surface 20, thereby can reduce the height of casing 30, this EFU fan filter uints is installed to after ceiling board, and EFU fan filter uints and in-house operation personnel's distance is elongated, and has reduced this fan filter uints noise effect.Therefore,, by forming such air channel, can reduce noise.
Filter in traditional fan filter uints be inlay card on the shell of casing, dismounting is inconvenient, and easy dust stratification; Filter 50 two ends in the fan filter uints that the utility model provides are provided with the bending part 51 that can be fixed on outlet air surface 20, between bending part 51 and outlet air surface 20, gasket seal 80 is set, with Anti-air-leakage, and contaminated air, this bending part 51 can be fixed on outlet air surface 20 by fastening screw trip bolt 52, easy for installation, be convenient to dismounting, prevent from leaking out, dust stratification.
On casing 30 in the utility model, in air inlet ring 10 both sides, be also provided with rotating handle 90, when fan filter uints leaves unused, handle 90 can be fallen, and not affect space; Controller 100 is arranged near one of them handle 90, is convenient to control.
For convenience of fan filter uints is installed on ceiling board, on casing 10 bi-side, be provided with fastening flange 31, fixed hole 32 is set on fastening flange 31, easy for installation.
EFU fan filter uints of the present utility model, by barge board and guide plate are set, have reduced stream pressure loss, has reduced power consumption, and Diffusion of gas stream is even, makes outlet air surface wind speed uniform and stable, and filter quick detachable, be difficult for dust stratification, easy to use.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this model utility technological thought, carry out various change and modification completely.The technical scope of this model utility is not limited to the content on specification, must determine technical scope according to claim scope.
