Abstract
The utility model discloses a material conveying fan impeller with back blades of a fan for conveying granular grain crops, which consists of a wheel plate with main blades, and is characterized in that a wheel disc is arranged on the back surface of the wheel plate, and the back blades are arranged on the wheel disc. Once grinding oil moves from the back surface of the impeller to a rotating shaft, the grinding oil can be thrown away under the action of the back blades and be sucked out from an air outlet, thereby fundamentally solving the leakage problem and prolonging the service life of a motor. The wheel plate and the wheel disc can be designed into a whole, thereby further simplifying the structure.
Description
Technical field: the utility model relates to a kind of blower fan of conveying granular material, particularly relates to a kind of impeller of conveying granular grain crops blower fan.
Background technique: conveying granular grain crops blower fan is mainly used in the field, storehouse now, the station, port and pier and grains crop production, the loading and unloading of processing industry, owing to usually contain grinding oil in the conveying granular grain crops, these grinding oils can slowly move to running shaft from the back side of draught fan impeller in course of conveying, leak out the gap between shell and running shaft then, can influence the environment on ground on the one hand, on the other hand owing on the running shaft grinding oil is arranged, dust in the meeting absorbed air, after using often, cumulative, have a strong impact on the rotation of running shaft, cause motor speed to descend, phenomenons such as corresponding reduction of transfer efficiency and motor intensification quickening.Some producer has adopted centrifugal pump to solve the working principle of leaking, and increases the mazy type sub-propeller on the running shaft of blower fan, though this structure has certain effect, still the seepage phenomenon can occur after the operating time is long, can not fundamentally solve leakage problems.
Summary of the invention: the purpose of this utility model is exactly to be to avoid above-mentioned the deficiencies in the prior art part and a kind of defeated material draught fan impeller with back blades is provided, the wheel disc of band back blades is installed at the back side of draught fan impeller, in case there is grinding oil to move to running shaft from the back side of impeller, effect by back blades, grinding oil is thrown away sucking-off from exhaust outlet.
The purpose of this utility model is achieved in that a kind of defeated material draught fan impeller with back blades, is made up of the wheel plate of band primary blades, and it is characterized in that: the back side at described wheel plate is equipped with wheel disc, and described wheel disc is provided with back blades.
Described wheel plate and wheel disc are an integral body.
The utility model compared with prior art has following advantage:
1. the wheel disc of band back blades is installed at the back side of draught fan impeller, in case there is grinding oil to move to running shaft from the back side of impeller, by the effect of back blades, grinding oil is thrown away, sucking-off from exhaust outlet fundamentally solves the problem of leaking, the working life of improving motor.
2. wheel plate and wheel disc are an integral body, further simplified structure,
Description of drawings:
