Abstract
A novel axial flow impeller comprises a hub, a fixing screw, a strengthening rib, a nut, an impeller, a conical surface, a rotating shaft hole, and a plurality of conical mounting holes, and is characterized in that the rotating shaft hole is arranged in the central position of the hub, the plurality of conical mounting holes are arranged on the side wall of the hub, the strengthening rib is arranged at the root part of the impeller, the conical surface is arranged at one end of the strengthening rib, the fixing screw is fixedly arranged inside the strengthening rib, the hub is connected with the impeller through the fixing screw, the conical surface (6) is matched with the conical mounting holes, the fixing screw can rotating the angle of the impeller during fixing process to regulate the quantity of wind power, and the axial flow impeller is made of SMC glass-reinforced plastic material. Compared with the prior art, the novel axial flow impeller has the benefits of convenient use, good acid resistance, alkali resistance, corrosion resistance and wear resistance, and prolonged service life.
Description
Technical field
The utility model relates to a kind of ventilation equipment, specifically a kind of novel axial-flow blower.
Background technique
At present, axial-flow blower of the prior art has two structures: a kind of is to adopt simple Structural Hardware, shortcoming is the corrosion of the acid-base material that is vulnerable to discharge in the blower fan, another kind is to adopt plastic construction, shortcoming is an easy deformation under the high-temperature condition, broken easily under the low temperature condition, thus cause reduce the working life of draught fan impeller.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of axial-flow blower of new structure of corrosion-resistant, long service life is provided.
The technological scheme that its technical problem that solves the utility model adopts is: its structure comprises wheel hub (1), retaining screw (2), stiffening rib (3), nut (4), impeller (5), conical surface (6), rotary shaft hole (7), taper mounting hole (8), it is characterized in that wheel hub (1) central position is provided with rotary shaft hole (7), the sidewall of wheel hub (1) is provided with several taper mounting holes (8), the root of impeller (5) is provided with stiffening rib (3), stiffening rib (3) one ends are provided with conical surface (6), retaining screw (2) is fixedly installed in the stiffening rib (3), wheel hub (1) is connected with impeller (5) by retaining screw (2), conical surface (6) matches with taper mounting hole (8), retaining screw (2) can rotary blade (5) in fixation procedure angle, regulate the size of wind-force, this axial-flow blower adopts SMC glass fibre reinforced plastic material structure to make.
The beneficial effects of the utility model are, the utility model is compared with prior art, and the axial-flow blower of this new structure is not only easy to use, acid-alkali-corrosive-resisting, wear-resisting, and long service life.
