Abstract
The utility model relates to a vortex fan; the utility model needs to solve that the utility model improves the air intake state of a fan so as to enhance exhaust rates of the fan and the complete machine efficiency. The utility model is composed of an impeller, a main shaft, a machine body and a machine cover, which is characterized in that an air quantity supply impeller is arranged between an air inlet of the machine body and a filter, the outside of the machine cover is provided with a casing which contains the air quantity supply impeller and communicates with the air inlet of the machine body, and the front end of the casing of the air quantity supply impeller is provided with the air inlet which is connected with the filter. The utility model can be used for replacing a Roots fan with equivalent capacitances.
Description
The utility model relates to Cyclone wind motor.
Existing Cyclone wind motor is made up of impeller, main shaft, fuselage, cover, the intake grill of fuselage connects filter, exhaust port connects baffler, fuselage and cover are provided with the bearing of supporting spindle, have sealing gasket and gland, main shaft can adopt coupling direct connection motor in the bearing outside or adopt belt wheel by diesel engine drag, the drives impeller running.This blower fan structure is simple, volume is less, does not still have the Cyclone wind motor that surpasses 7.5KW at present.
The purpose of this utility model provides a kind of compound blower fan of vortex that can improve Cyclone wind motor air intake state, raising blower fan exhaust air rate, improve overall efficiency.
The utility model is made up of impeller, main shaft, fuselage, cover, between the intake grill of fuselage and filter, be provided with air quantity supply impeller, air quantity supply impeller is installed on the projecting shaft of front-end of spindle, in the cover outside housing that holds air quantity supply impeller and be communicated with the fuselage intake grill is arranged, establish intake grill at the housing front end of air quantity supply impeller and connect filter.
Established air quantity supply parts by what the utility model, can improve the air intake state of Cyclone wind motor, facilitated blower fan exhaust air rate and overall efficiency obviously to improve, for Cyclone wind motor increase capacity provides a kind of simple and direct mode.
Accompanying drawing is represented structural representation of the present utility model.
Realize best way of the present utility model below in conjunction with description of drawings:
3 is air quantity supply impellers that the utility model is provided with in the accompanying drawing, this air quantity supply impeller 3 can adopt centrifugal impeller, especially be fit to adopt the closed centrifugal impeller, on the wheel disc of closed centrifugal impeller, establish airflow hole and can cause circulating air flow in the housing, help disperseing to take out of the heat of cover 2; Air quantity supply impeller 3 is installed on the projecting shaft of main shaft 6 front ends, and adopts fair water cone fastening; Establish intake grill 1 at the front end of the air quantity supply impeller housing of the arranged outside of cover 2 and connect filter.4 expressions main impeller of the present utility model in the accompanying drawing, the blade of main impeller 4 extends to the impeller center can expand fan capacity, leak increase for the both ends of the surface of avoiding main impeller 4, between main impeller 4 and fuselage 8 and cover 2, make concavo-convex alternate mazy type combining structure and can effectively reduce leakage.5 expression exhaust ports in the accompanying drawing are received air quantity that the outlet of air quantity supply will be unnecessary and are fed back and carry out air demand adjusting energy efficient but from exhaust port 5 bypass valve is set; The rear portion that by-pass line is received fuselage 8 is established in the outlet of air quantity supply, can help the fuselage heat radiation.7 is glands in the accompanying drawing, utilizes adjustment gland and sealing gasket accurately locate for impeller.Can break through the present situation that Cyclone wind motor only adopts in the smaller power scope in the manner described above, the utility model single-machine capacity can reach 15KW, can partly replace suitable " Roots " blower fan of capacity.
