In food processing process, the carrying of (as the melon of fermentation plant is dry, barley, rice, the powder of flour mill, the seed material of oil plant factory etc.) bulk granular material of, powdery granular for some and to carry be much that the mode of carrying with air-flow is carried out.This is to have a lot of irreplaceable advantages of other mode of movement because people in long-term production practice, have recognized air-flow mode of movement gradually.Such as the sealing of: course of conveying (formula pneumatic conveyer is sent in the suction that especially pipeline system is negative pressure state), material loses very little in course of conveying, and carry place airborne dust greatly to reduce, avoided the pollution to environment and improved productive labor condition; The production efficiency of carrying is higher, particularly in the conveying to bulk granular shape, granular material, can more conveniently realize automation mechanized operation, reduces shipping and delivery cost.The form that air-flow is carried is a lot, as according to the material being transferred, the flow regime in transfer line can be divided into suspension conveying and promote to carry two classes; And suspension conveying can be divided into again inhaling and send pressure combined three kinds of formula, pressure sending type and suction.In food-processing industry, adopting more is to inhale to send formula air-flow mode of movement, the ease for operation that it is carried for air-flow, and reliability and spatter property more easily represent.Send in formula flow delivery systems in suction, loader is extremely important parts, and this is that the performance of loader will directly affect whole system because first the material being transferred must be sucked into conveying pipeline by loader with air.Because food processing is generally to carry out in workshop, feeding place is fixed, if material is directly to fall from hopper or container, so loader adopts fixed type material feeding mouth conventionally.No matter current fixed type material feeding mouth is the form such as Y shape or L shaped or r shape, all to allow air-flow and streams shape import in an angle conveying pipeline, because air-flow and streams are unidirectional contacts, the homogeneity of gas distribution is poor, be difficult to obtain preferably mixture ratio, just easily there is the dead angle of air-flow in this, form the monolateral accumulation of material and be prone to material bolt in the transfer line of back segment, makes the whole device parking maintenance of having to.
Summary of the invention
The purpose of this utility model is to provide the fixing material feeding mouth of a kind of induction type around, overcomes at present and send the fixed type material feeding mouth adopting in formula flow delivery systems because the poor transfer line that makes of homogeneity of gas distribution is prone to the deficiency of expecting bolt in suction.
The utility model is achieved by following technical proposals.
The utility model comprises hopper and dress current plate and conveying pipeline thereon, be provided with material feeding elbow, the import of described material feeding elbow and the connection of the discharging opening of described hopper, its outlet and described conveying pipeline are communicated with, on described material feeding elbow, gas guide nozzle is housed, the admission port of described gas guide nozzle outside the wall of described material feeding elbow, its air extractor duct stretches in described material feeding elbow, its outer wall is fixedly connected with hermetically with the outer wall of described material feeding elbow.In the technical program, described hopper, current plate and conveying pipeline are to inhale at present the common prior art of sending formula flow delivery systems.Described gas guide nozzle is in the time making assembling, should make every effort to allow its central axis and the central axis of described conveying pipeline coincide, like this, due to the negative pressure of system, extraneous air is to advance along the central axis of described transfer line after being imported by described gas guide nozzle, spread to the tube wall of surrounding equably simultaneously, make the suffered pneumatic floating power of the material that is transferred and the propelling thrust radial distribution that moves ahead more reasonable, material gas mixture ratio also easily reaches preferable states, streams is smooth and easy the moving ahead of energy in described transfer line, in pipeline, also there will not be and occur expecting bolt because of the monolateral accumulation of material.Generally, described gas guide nozzle can be made into circle, is made into exit skirt, to reduce the resistance to importing air-flow in the part of described material feeding elbow outside; Simultaneously the air extractor duct of described gas guide nozzle do circular after, around air extractor duct, can form the induction district of a circle to material, can make the material being fallen by described hopper more effectively flow into described conveying pipeline with air-flow.
For food processing enterprises, food material is various in style, and a pneumatic conveyer often will be born the conveying of the material of multiple kinds; Even the material of same kind, also before and after existing batch in the difference of the aspect such as fineness degree, humidity, in order to make the conveying of the novel applicable different quality materials of this reality, can suitably will on the air-flow above-below direction being flowed out by described gas guide nozzle, finely tune, for this reason, on the air extractor duct of described gas guide nozzle, airflow fence is housed, the control stalk of described airflow fence is housed simultaneously.
Against existing technologies, the beneficial effects of the utility model are:
Can make system even to the gas distribution of material at storage end, around described gas guide nozzle, can not form the accumulation of material simultaneously, make the smooth and easy transfer line that enters of streams energy, improve the output of system.
