Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of low pressure ejector will of the present utility model;
Fig. 2 is the left view of a kind of low pressure ejector will of the present utility model.
Detailed description of the invention
Contriver of the present utility model, in order to understand the technical solution of the utility model better, is described in detail by reference to the accompanying drawings below by embodiment particularly:
Refer to Fig. 1 and Fig. 2, a kind of low pressure ejector will of the present utility model, comprise air inlet pipe fitting 1, high velocity projector 2, blending box 3, hopper 4, drainage tube 6 and diffuser 7.
Blending box 3 is divided into airflow inlet end and airflow outlet end in the horizontal direction, and the top of blending box 3 is communicated with the neck of hopper 4 bottom.
Air inlet pipe fitting 1 is socketed with the inlet end of blending box 3, and the inlet end of air inlet pipe fitting 1 is positioned at outside blending box, is provided with an inlet flange.The inlet end of blending box 3 is stretched in the outlet side of air inlet pipe fitting 1.Seal between the excircle of air inlet pipe fitting 1 and the inlet end of blending box 3.The inlet end of high velocity projector 2 is socketed with the outlet side of air inlet pipe fitting 1 in blending box 3.In high velocity projector 2, jet-stream wind should meet the requirements of high velocity air, can not have very high pressure drop, causes higher energy consumption; The size of high velocity projector 2 can adjust according to the difference of jet length and operational throughput, to reach optimized conveying effect.High velocity projector 2 outlet side is positioned at immediately below hopper 4 outlet.
The inlet end of drainage tube 6 and the inner peripheral wall of blending box 3 outlet side are socketed, and the inlet end of diffuser 7 is connected with the outlet side of drainage tube 6, and the outlet side of diffuser 7 is provided with flange of giving vent to anger.
Low pressure ejector will needs to suck air from air, and the material in hopper 4 can be flow in blending box 3 under suction function.With source, the top of the hopper 4 of a kind of low pressure ejector will of the present utility model directly can expect that feed bin is connected, form airtight feed status, can not make material spilling or form airborne dust; And enter in blending box 3 in order to suck air from air together with material, the circle wall on hopper 4 top adds suction grille.
The top of the hopper 4 of low pressure ejector will of the present utility model is provided with communication port 51, with the source that material is housed, communication port 51 expects that feed bin or hopper are directly connected; The inlet flange of air inlet pipe fitting 1 inlet end is connected, as whirlpool blower fan etc. with conveying source of the gas; The flange of giving vent to anger of diffuser 7 outlet side is connected with Pneumatic conveying pipeline.After material enters this Pneumatic conveying pipeline, be transported in finished product bin or container under the effect of conveying gas.
