Abstract
The utility model discloses a device for delivering a solid powdery material. The device comprises a venturi ejector, and a pressure regulator and a guide pipe, which are arranged at the two opposite ends of the venturi ejector. The venturi ejector comprises an air inlet pipe, an acceleration cavity connected with the air inlet pipe and an air outlet pipe connected with the acceleration cavity. The air inlet pipe is provided with an inlet, and the air outlet pipe is provided with an outlet. The pressure regulator is connected with the air inlet pipe, and is close to the inlet. The guide pipe is connected with the outlet of the air outlet pipe. A material inlet is formed above the acceleration cavity, and the solid powdery material enters the material inlet. The air inlet pipe comprises an air inlet cavity in which compressed air flows, and the cross sectional area of the air inlet cavity is progressively decreased in a direction from the inlet to the acceleration cavity. The air outlet pipe comprises a discharge cavity from which the solid powdery material and the compressed air flows, and the cross sectional area of the discharge cavity is progressively increased in a direction from the acceleration cavity to the outlet. According to the whole delivery device, the loss of the powdery material can be prevented, and the addition of a product can be ensured.
Description
Technical field
The utility model relates to a kind of feedway, more particularly, relates in particular to a kind of feedway for the solid state powder material.
Background technology
What usually solid material adopted in process of pneumatic transmission is the material-transporting system that blower fan adds rotovalve, and material utilizes the self gravitation blanking, is seen off by low-pressure air after entering rotovalve again.In this process, air is malleation in the material conveying pipe, and inevitably there is movement clearance in rotovalve, always there is the Partial shrinkage air to scurry into material inlet by pipeline, if the gravity that material (such as powder) falls is less than the buoyancy of the air of scurrying out, material will be blown away by air so, can't enter rotovalve and carry.Adopt blower fan to add the material-transporting system of rotovalve, can cause that powder material blows the mistake problem, and then cause loss of material, addition inaccuracy.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of feedway that is used for the solid state powder material that prevents loss of material is provided.
The technical solution of the utility model is achieved in that a kind of feedway for the solid state powder material, it comprises venturi-type eductors, be arranged on pressure regulator and the guide pipe of venturi-type eductors opposite end, this venturi-type eductors comprises air inlet pipe, the accelerating cavity that links to each other with air inlet pipe and the freeing pipe that links to each other with accelerating cavity, air inlet pipe and freeing pipe are respectively equipped with entrance and exit, pressure regulator links to each other with air inlet pipe and close entrance, guide pipe links to each other with the outlet of freeing pipe, the top of accelerating cavity is provided with the inlet point that enters for the solid state powder material, described air inlet pipe comprises the inlet chamber that the voltage supply stream of compressed air is moving, and successively decreases on the direction of the cross-sectional area of this inlet chamber from the entrance to the accelerating cavity; Described freeing pipe comprises the discharging chamber for solid state powder material and pressurized air outflow, and the direction of the cross-sectional area in this discharging chamber from accelerating cavity to outlet increases progressively.
Described feedway connects the trunk line for delivery of granule materials, and guide pipe is provided with the export mouth identical with trunk line endoparticle mass transport direction.
The utility model is by being provided with venturi-type eductors, being arranged on pressure regulator and the guide pipe of venturi-type eductors opposite end, the air inlet pipe that venturi-type eductors is provided with the inlet point that enters for the solid state powder material, enter for the compression air and the freeing pipe that flows out for solid state powder material and pressurized air, pressure regulator can be regulated the compressed-air actuated pressure in the venturi-type eductors; The intracavity section of air inlet pipe is long-pending to successively decrease from outside to inside, is conducive to improve compressed-air actuated speed; And then the degree of vacuum at control inlet point place, be conducive to the solid state powder material and suck venturi-type eductors; The intracavity section of freeing pipe is long-pending from inside to outside to be increased progressively, and is conducive to powder material and discharges under pressurized air, and whole feedway can prevent the powder material loss and guarantee the product addition.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not consist of any restriction of the present utility model.
