Detailed description of the invention
The invention provides the air-duct apparatus being applied to clarifier, noise is low, air pressure air flow is large, cost is low.Below in conjunction with accompanying drawing, technical solution of the present invention is described in detail, is easier to make it understand and grasp.
As shown in Figure 2, be applied to the air-duct apparatus of clarifier, air-duct apparatus is used for the exhausting air inlet of clarifier, extraneous air is imported in clarifier and purifies, discharge after purification, circularly purifying air-flow reaches the object of purification, the centrifugal blower 2 that this air-duct apparatus comprises duct main 1 and is arranged in duct main 1, centrifugal blower 2 comprises fan blade 8, duct main as shown in Figure 7, the wind inlet end 3 of duct main 1 has an air dam expanded from inside to outside 4, air dam is funnel-form, bell mouth shapes etc. expand form shape from inside to outside, preferably, the narrow end of air dam is circular, the wide end of air dam is rectangle, the form expanded from inside to outside can increase the air inflow in air channel, when centrifugal blower starts, centrifugal blower has the guiding force along wind direction to air dam inner air, air in air dam along its narrow end to wide end by the guiding force of centrifugal blower from large to small, in the wide end of air dam, air stores by air dam guiding, can not go out because of by guiding force is little and free, therefore improve the kinetic energy efficiency of centrifugal blower, ensure the air inflow in air channel, and through the effect of air dam, the air in air dam is made to be subject to the guiding force effect of centrifugal blower larger, the stable inlet air of air-duct apparatus is even, be conducive to the later purification of clarifier.
Wherein, there is between the inwall of duct main 1 and the side of fan blade 8 passage 5 for airflow, this passage 5 can provide the break-in distance of air-flow, the radial motion power making fan blade 8 in centrifugal blower throw away wind decays and complies with the axial flow direction, the inwall of duct main 1 can further be optimized, it has a guiding curved portions 7, and this guiding curved portions 7 is arranged in the outlet air end lateral location of centrifugal blower 2 fan blade 8.This guiding curved portions 7 effectively can change wind direction stably, reduces air loss.
In addition, as each schematic diagram that Fig. 4 to Fig. 6 is fan blade, the side that fan blade 8 deviates from air dam 4 has in funnelform wind deflector 6, the narrow end of this wind deflector 6 is towards air dam 4 side, the airflow centrifugal of importing throws away by fan blade 8, namely throw away along the move tangential direction of periphery of fan blade 8, and by wind deflector 6 pairs of air-flows, there is guide effect, concrete, air flow in air-duct apparatus work is as shown in dotted line in Fig. 3 14, the sidewall of the wind direction and duct main that make centrifugal blower throw away air-flow has angle of inclination, prevent wind direction vertical, decrease air loss, reduce noise.More refinement, is optimized wind deflector, and wind deflector 6 be 45 ° ~ 60 ° angles 13 with the axis of fan blade 8, through test, and the effect optimum of this angle 13 scope internal air baffle.
This programme is optimized, and all has to meet to assemble the gap run between the bottom of fan blade 8 and the inwall of duct main 1, and the gap in this case is for increasing resistance gap 9.Play by reducing gap the effect increasing resistance, the width increasing resistance gap 9 is preferably 1 ~ 3mm, this width and the gap between fan blade and air channel.
Concrete, the bottom of fan blade 8 has concave arc end wall 10, and the inwall of duct main 1 has the convex arc wall 11 matched with concave arc end wall 10, is formed to increase and hinder gap 9 between concave arc end wall 10 and convex arc wall 11.The design of arc further increases the resistance of extraneous air in increasing resistance gap, forces extraneous air all to be entered by fan blade, can not invade from gap.Certainly also can be optimized, in order to ensure the stability increasing resistance gap, the slot end face of air dam 4 is mutually coplanar with the bottom face of fan blade 8, increases the increasing resistance of resistance gap more stable.
This programme also can be optimized further, and increase the diameter of the wind inlet end of fan blade, the port diameter of concrete fan blade 8 wind inlet end is at least 3/4 of wind blade main body diameter, and so design can increase air inflow further.
Finally, the wide end of air dam 4 has along limit 12, and this facilitates the assembling of air-duct apparatus along limit 12, can be used for supporting increase frictional force, easily can be used for assembling filter mechanism.In addition, it should be noted that, the filter mechanism of clarifier is positioned at the air intake vent side of duct main, namely the air inflow etc. of air-duct apparatus has direct impact to the filter effect of filter mechanism, and the air-duct apparatus of this case effectively can increase the blast of air inlet, indirectly improve the filter effect of clarifier.
Above abundant description is carried out to technical scheme of the present invention; it should be noted that; the specific embodiment of the present invention is not by the restriction of foregoing description; those of ordinary skill in the art adopts equivalents or equivalent transformation and all technical schemes formed according to Spirit Essence of the present invention in structure, method or function etc., all drops within protection scope of the present invention.
