The utility model content
For addressing the above problem, the utility model provides a kind of Pneumatic conveyer, and it is adjustable that the conveying of material is stablized, and reduces the wearing and tearing to pipeline, cuts down the consumption of energy.
For achieving the above object, Pneumatic conveyer of the present utility model, comprise air compressor, storage tank, loading hopper, storage tank, screw feeder, Material pipeline and spray gun, described air compressor is divided into two-way after delivering the gas to described storage tank, wherein one road gas enters described storage tank, and another road gas enters the material delivery port of described screw feeder; Described loading hopper is arranged on the top of described storage tank, and described screw feeder is arranged on the below of described storage tank, and an end of described Material pipeline links to each other with the material delivery port of described screw feeder, and the other end connects described spray gun.
Preferably, described spray gun is a plurality of.
Pneumatic conveyer of the present utility model is applicable to the powdery or the granular material conveying of industries such as chemical industry, metallurgy, food, pharmacy.
Pneumatic conveyer of the present utility model under storage tank internal gas pressure and material deadweight effect, is full of the import of screw feeder, can effectively prevent problems such as getting stuck in the course of conveying, material segregation and bridge formation, and can effectively improve the material-gas ratio of course of conveying; Adopt screw machine to force the feeding method by screw feeder, thereby guaranteed the continuity and the stability of feeding; By the screw feeder motor gear box, realize feeding coal adjusting arbitrarily in certain scope, to satisfy the best winding-up amount of mass transport.
By Pneumatic conveyer of the present utility model, realized that stablizing of mass transport is adjustable, reduced wearing and tearing, reduced energy consumption delivery duct.
Description of drawings
Fig. 1 is the process equipment diagram of circuit of Pneumatic conveyer of the present utility model.
The specific embodiment
Fig. 1 is the process equipment diagram of circuit of Pneumatic conveyer of the present utility model, as shown in the figure, Pneumatic conveyer of the present utility model comprises air compressor 1, storage tank 2, loading hopper 3, storage tank 4, screw feeder 5, Material pipeline 6 and spray gun 7, described air compressor 1 is divided into two-way after delivering the gas to described storage tank 2, wherein one road gas enters described storage tank 4, for the quantitative spiral output of material in the jar provides constant interior pressure and propelling thrust, another road gas enters the material delivery port 51 of described screw feeder 5, enter Material pipeline 6 as assist gas, at any time purge the material of spiral output, and timely injectant material conveying tube 6.
Storage tank 2 is installed after the air compressors 1, can not only storing compressed air, reduce because the pressure pulsation of the discontinuous generation of air compressor 1 exhaust, and realize air feed and with the balance of gas.
The gas control valve 11,12,13 that is provided with on gas circuit can be used for the adjusting of gas flow or the switch of gas circuit.
Described loading hopper 3 is arranged on the top of described storage tank 4, and described screw feeder 5 is arranged on the below of described storage tank 4, and an end of described Material pipeline 6 links to each other with the material delivery port 51 of described screw feeder 5, and the other end connects described spray gun 7.
Material to be carried after loading hopper 3 is discharged into described storage tank 4, under jar inner high voltage and deadweight effect, is loose shape and is piled up in tank body bottom (and the suspended state in the non-traditional pneumatic conveying mode), quantitatively exports through screw feeder 5; Material is blown into spray gun 7 at a high speed by assist gas immediately after spiral output enters Material pipeline 6, be injected to the receiver (not shown) then, finishes whole process of pneumatic transmission.Described receiver is the final terminal that material need be carried, such as high temperature furnaces such as blast furnace, coke oven, converter, cement rotary kilns.
The utility model is applicable to the conveying less than 15mm, no adhesion, dry tiny solid particle and granular material of plastic grain, rubber grain, coal dust, fly ash, lime equigranular.
Described screw feeder 5 mainly comprises by conveying screw rod and change-speed motor 52.Conveying screw rod is the screw rod that a constant pitch is arranged, screw rod is positioned at the bottom of described storage tank 4, driving screw rod by change-speed motor 52 rotates, by regulating the rotating speed of change-speed motor 52, can change the rotating speed of screw rod, can change the delivery rate of described screw feeder 5, thereby reach the purpose of quantitative outputting material.
According to the material difference of being carried, assist gas is also different at velocity in pipes, and flow rate of carrier gas is by being provided with flow counter and control cock is regulated on pipeline, thereby according to the winding-up requirement, provides best material-gas ratio.
Described spray gun 7 can be one or more, and the layout of the caliber of each spray gun, length and shape should be similar with design, so that spray gun internal resistance damage is equal as far as possible, reaches the purpose that the even strength of material is carried.Described spray gun end outlet pressure should be higher than the receiver internal pressure at least, so that material sprays smoothly.Described spray gun 7 can adopt traditional sleeve-type, inner core winding-up material, urceolus spray cold air.
