Abstract
The utility model relates to an air delivery centrifugal fan to blow objects, and comprises an enclosure body, an air inlet, an air outlet and a fan shaft. A base plate parallel with a sideboard of the enclosure is provided on the fan shaft in the enclosure; an annular front dish parallel with the base plate is provided on the base plate; fan blade plates are provided between the base plate and the annular front dish and are at an oblique angle with the base plate. A wind shield cover is provided on the base plate and is parallel with the base plate, and the wind shield cover is connected with the base plate through a support. The fan blade plates of the utility model are positioned radially comparing with those of prior fans, which not only reduces angle of wind direction, but also regulates air current direction inside the fan so that vortex on both sides of the fan blades is significantly reduced, efficiency of the fan is improved, dissipation of energy is reduced. In addition, the utility model has the advantages of few damages to conveyed materials, and is therefore extremely applicable for conveyance of such articles, as cotton and so on.
Description
Technical field:
The utility model relates to a kind of suction of conveying material and blows over thing strength conveying centrifugal blower.
Background technique:
Common blower fan, the blower fan in particular for mass transport is used blows the blower fan of unginned cotton as blower fan and the Lei Shi suction of band picogram dragon, because on its structural design, efficient is lower, effect is bad when conveying material.
Summary of the invention:
The purpose of this utility model is to provide a kind of efficient height, the effective suction that is used for conveying material of conveying material to blow over the thing strength and carries centrifugal blower.
The utility model comprises the flow blower casing body, intake grill, exhaust outlet and fan shaft, it is characterized in that the fan shaft in the housing is provided with the base plate parallel with the housing side plate, on base plate, be provided with and base plate parallel annular shroud, between base plate and annular shroud, be provided with the fan impeller, the fan diameter that the fan impeller constitutes is greater than base plate and annular shroud diameter, and described fan impeller and base plate have a non-perpendicular angle α, be that the fan impeller is skewed on base plate, on base plate, be provided with the current plate parallel with this base plate, this current plate is in the other end of fan, one axial gap is arranged between current plate and the fan, be connected with support between current plate and the base plate.
The angle α that tilts between above-mentioned fan impeller and the base plate is best≤and 45 °.
Compare with existing blower fan, the utility model is radially installed the fan impeller, and with base plate non-90 ° of angles are arranged, the angle that not only facings the wind reduces, and transfer along the fan internal gas flow flow to, the eddy current of fans both sides is greatly reduced, improved the efficient of blower fan, reduced energy consumption, and have simple in structure, conveying material is effective, to the low advantage of the material extent of damage of being carried, be highly suitable for carrying as class article such as cottons.
