Abstract

The invention relates to an air conveying system and air conveying method for powder materials. Discharging hoppers are arranged at two ends of a sending tank of the air conveying system respectively, conveying belts are arranged on both sides of each discharging hopper, and a lifting hanger is arranged above each discharging hopper. The lifting hangers lift bags on the conveying belts to the discharging hoppers, a sucking head on each discharging hopper is connected with the sending tank through a venturi tube, and the discharging hoppers connected with a dust collecting device. The method includes vacuumizing the sending tank by the aid of compressed air through the venturi tubes to generate sucking force, and using the sucking heads to suck power materials in the bags into the sending tank for temporary storage. A valve of the sending tank changes flowing direction of the compressed air to generate positive pressure and air flow, materials in the tank and air are mixed into fluid, and the mixture of the materials with the air flows like fluid in a pipeline to reach a destination collecting bin. The air conveying system for powder materials is free of bag breaking and dust flying, high in precision, few in impurities, compact, small and suitable for being used in environments with larger throughput and requirements of strict control of dust emission.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
Referring to Fig. 1 to Fig. 4, the invention provides a kind of powder and granule shape material blast system, it mainly is made up of lifting hanger 2, conveyer belt 3, transmission jar 4, dust arrester installation 5, suction head 12, Venturi tube and the pipeline of lifting bag bag.
The two ends of sending jar 4 are provided with discharge hopper respectively, and the two ends of sending jar 4 also are provided with conveyer belt 3 respectively.This conveyer belt 3 can adopt the plate chain type conveyer belt.On transmission jar 4 tops lifting hanger 2 is set, lifting hanger 2 rises to discharge hopper with bag bag on the conveyer belt 3, and discharge hopper is provided with suction head 12 up, and suction head 12 sends jar 4 through the Venturi tube connection.Suction head 12 is trunk shape, and it is equipped with the corrosion-resistant steel suction head, is provided with in the suction head 12 to help the gas pad.
Discharge hopper connects dust arrester installation 5 through a flexible pipe 6; Send jars 4 and be connected to Air compressor 1 through air inlet pipe 7.Send jar 4 and also connect an outlet conduit 8.Lifting hanger 2 is provided with the suspension ring that entangle four jiaos of bag bags.
The present invention also provides a kind of powder and granule shape material wind delivery method, utilizes high pressure air to pass through Venturi tube, will send a jar interior air extraction, makes to send jar and transfer negative pressure to, makes suction, through suction head the material in the bag be drawn into send jar temporary.After treating that all powder material are sucked into; Send the valve of jar and regulate, change air-flow direction, pass through Venturi tube once more through the stored program controlled control computer; Make malleation and air-flow; Let jar interior material and air puddle near fluid state, then because of the generation pressure reduction between the rewinding storehouse, in the jar and destination, making flows as material and the air-blending image fluid arrives rewinding storehouse, destination.
Whole suction and course of conveying all carry out at confined space, do not have dust and leak; Adding a jar interior material is that process is puddled also " fluidization " with air earlier, therefore can in jar or on the pipeline, not leave remnants, has both improved particularity, has also reduced material waste and impurity.The present invention is suitable for the big environment use down that also needs strict control dust emission of loading and unloading capacity.
Below describe the structure and the working process of powder and granule shape material blast system of the present invention in detail.
A kind of powder and granule shape material blast system of the present invention mainly is made up of oil pressure lifting hanger, conveyer belt, transmission jar, dust arrester installation, suction head, Venturi tube and the pipeline of lifting bag bag, and carries out process control by PLC.After the bag bag is transported to the plate chain type conveyer belt by fork truck or driving; The operator can press switch on remote control unit; After the plate chain type conveyer belt is delivered to assigned address to the bag bag, be attached to the electric block that sends on the tank bracket and can reach assigned address by the operator, the suspender belt that wraps bag four jiaos is set on the suspension ring; Rise the bag bull ladle by electric block again, and it is moved to the hopper top.Then, start Air compressor, start the transmission jar and make it the entering program, start dust arrester installation, untie a bag bag bottom discharging sack again, let material through conducting oneself with dignity and sending jar from the suction inspiration of hopper.For preventing to build bridge, hopper top the right and left respectively has a massage thin plate, is connected on bucket body one side through two pneumatic reservoir tubes of gas.During startup, the pneumatic reservoir tube of gas is flexible and therefore make left and right sides thin plate push away mutually shaking, shake bag and so that inner powder can arranged fully to fall.After treating that level sensor or the time that presets arrives, after the completion, system gets into router.
The discharging program can closed and get into to the valve that is connecting dust arrester installation.In the discharging program, other has two valve openings, changes the direction that air communication is crossed Venturi tube; Simultaneously through helping the gas pad to sending a jar injecting compressed air; Transfer malleation sending jar to from negative pressure, and force powder and granule shape material and air-blending, become fluid state; Extruded outside the jar by a jar interior malleation, arrive the rewinding storehouse of destination through conveying pipeline.After treating that line pressure decline or Preset Time arrive, send jar and be reduced to readiness for action, wait next instruction.
When the bag bag unloaded clearly, the operator can put down lifting hanger to default location, untied the Recycling of empty bag, and loaded onto new bag bag next discharging cycle of entering.Be positioned at the lifting hanger and the discharge hopper alternation of position, the left and right sides, to the greatest extent at utmost use the inspiration of sending jar to extrude ability, make maximizing efficiency.
In sum, powder and granule shape material wind of the present invention send the equipment need not bale broken, airborne dust not, and accuracy rate is high, and impurity is little, and compact; Because can one the support of cover transmission system more than one material sucking port, need not any extra mechanical device except that pipeline; Adding pipeline can move towards flexibly, is fit to the high factory building of space density.The present invention is suitable for the big environment use down that also needs strict control dust emission of loading and unloading capacity.
Certainly; Those skilled in the art in the present technique field will be appreciated that; The foregoing description only is to be used for explaining the present invention; And be not with opposing qualification of the present invention, as long as in connotation scope of the present invention, all will drop in the scope of claim of the present invention the variation of the foregoing description, modification etc.
