Abstract
The utility model discloses a pneumatic unloading device for canned powdered materials, which is the device of pneumatic conveying bulk canned tankers or powdered materials of fixed bulk canned tankers. The existing pneumatic unloading device for canned powdered materials has a large unloading resistance and low unloading capability. Besides, the existing pneumatic unloading device for canned powdered materials has a phenomenon of a blast of materials and a blast of gas. The utility model carries out improvements that the pneumatic unloading device for canned powdered materials is provided with a blast fence and the blowing assistant method of a conveying pipe is improved because the utility model wants to improve the unloading capability, which obviously improves the conveying capacity. The conveying distance of horizontal direction can be reached to 150 meters. The conveying distance of vertical height can be reached to 40 meters. The unloading speed can be reached to 1.6 tons/minute and the residual amounts are under 0.2%.
Description
" canned powder gas handler " is strength delivery of bulk tank car or fixing a kind of device of bulk pot granular material.
In canned powder gas handler, crucial problem is how further to improve the traffic capacity of material.Be provided with in the powder jar of effluent plate, gasification board, air inlet pipe, discharge duct by the tank body bottom at present, adopt this class powder jar gas handler of up feeding, directly facing to gasification board, gasification board is to be supported by stephanoporate steel plate to material sucking port.What adopt at the pressurized air auxiliary blowing apparatus on the conveying pipeline is that compressed air inlet pipe directly is connected in and helps blowing compressed air on the conveying pipeline or adopt and adorn a chuck on conveying pipeline, and pressurized air enters the parallel blowing compressed air that helps with the conveying pipeline wall behind the interlayer by air inlet pipe.This device for discharging gasification board compressed air directly blows to material sucking port by gasification board.Reduced the difference of pressure at material sucking port place, to the big resistance of the mobile generation of material, and gasification board by compression air effect raise up, can not guarantee the reasonable distance of material sucking port and gasification board, even the obstruction material sucking port.On the other hand, stephanoporate steel plate under the gasification board reduces air and gasification board direct contact surface, influences the uniformly penetrating of pressurized air to material on the gasification board, has reduced the mixture ratio of air and material, fully fluidization of material produces material " channel ", " turbulent " phenomenon.Conveying pipeline auxiliary blowing apparatus structure exists and to help that to blow the dead angle big, and air and mixing of materials are inhomogeneous, produces defeated one gas phenomenon of one material when expecting.The problem that prior art exists has limited traffic capacity.
The objective of the invention is to unload the powder feedway for improving said this class gas, formulate a kind of new structure, solve problems of the prior art, improve traffic capacity, simple in structure, cost is low, and is easily manufactured.
For solving this task, its feature of improvement structure provided by the invention comprises: establish a baffle plate (Fig. 1) facing to the material sucking port place on gasification board, directly blow to material sucking port to block the gasification board compressed air by gasification board, this baffle plate can be to be provided with on gasification board, also can be that this structure is set on the gasification board carriage, or be stained with to be coated in sir-tight material and replace baffle plate on the gasification board; With the stephanoporate steel plate cancellation of gasification board, gasification board is by the direct fixed pedestal of framework; Auxiliary blowing apparatus employing jacket type porous on the conveying pipeline helps blows, and bores the single row or multiple rows pore on the anterior conveying pipeline of chuck, and this hole and conveying pipeline axis are into about 30-degree angle (Fig. 2).
Experiment shows that the present invention effectively raises air and mixing of materials ratio, makes the abundant fluidization of material, reduce resistance, significantly improved traffic capacity, reached 150 meters of fed distance levels, 40 meters of vertical dimensions, 1.6 tons/minute of discharge rates, surplus is below 0.2%.
The following description of drawings of embodiments of the invention:
Fig. 1 is a constructional drawing of the present invention.1-tank body wherein, 2-effluent plate, the 3-gasification board, the 4-baffle plate, the 5-material sucking port, the 6-support frame, 7-conveying pipeline, 8-chuck, 9-help and blow into tracheae, 10-pore, 11-air inlet pipe.
Fig. 2 is the principle schematic of conveying pipeline auxiliary blowing apparatus of the present invention.
Device shown in Figure 1 is furnished with air compressor, does not draw among the figure.Air inlet pipe 11, air inlet pipe 9 link to each other with air compressor, and by air inlet pipe 11, air inlet pipe 9 is advanced in gasification board bottom and the conveying pipeline 7 air compressor air.The pressurized air that enters gasification board bottom makes fluidization of material by gasification board 3 and mixing of materials, in jar with the effect of conveying pipeline difference of pressure under, enter material sucking port 5, by conveying pipeline 7 dischargings.Baffle plate 4 below material sucking port 5, blocked the air-bed compressed air and directly blowed to material sucking port 5 by gasification board 3, because the existence of baffle plate 4, so just guaranteed the mix spacing of material sucking port 5 with gasification board 3, reduced the amount of air that directly enters material sucking port 5, therefore increased the difference of pressure at material sucking port place, reduced air directly enter material sucking port 5 and produce to the Flow of Goods and Materials resistance, reach the raising unloading performance.
Because the present invention has removed the stephanoporate steel plate that supports gasification board, simplify the structure, and the gasification board compressed air distributes more even on gasification board 3, ventilative amount increases, air and mixing of materials are more even, therefore the abundant fluidization of material can improve the Flow of Goods and Materials ability, has solved " channel ", " turbulent " phenomenon.
Fig. 2 has described conveying pipeline auxiliary blowing apparatus of the present invention, bores single row or multiple rows pore 10 at chuck 8 anterior conveying pipeline 7 upper edge circumference, and it and conveying pipeline axis are into about 30-degree angle.Pressurized air blows into tracheae 9 and enters in the interlayer by helping, and enters material in conveying pipeline 7 boost tubes by pore 10.Windstream enters in the conveying pipeline and can evenly rationally distribute like this, when pressurized air enters conveying pipeline at a high speed material is imposed actv. and quickens to promote, and further improves traffic capacity, and material is evenly carried continuously.
