Description
Technical field
The utility model relates to the powder material delivery device, is specifically related to a kind of powder material air pulsing device for discharging.
Background technology
For powder material, when utilizing gravity to carry out discharging by the discharge valve that is positioned at container bottom, very easily produce retention layer at the conical funnel place of device for discharging or discharge port occurs and stop up.For powder can all be drawn off from the valve of container bottom swimmingly, oscillatory system is set on container in the prior art employing or the aerated flow gasifying device solves the not smooth problem of powder material discharging.But these auxiliary discharging devices during for the poor powder material of flowing power, usually require multiple auxiliary discharging device to be used in combination and could meet job requirement, and this makes the complex structure of device for discharging, and cost of manufacture improves, and over-the-road expense and maintenance cost increase.Use oscillatory system, to also having a certain impact in service life of container simultaneously.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of simple in structure, cost of manufacture is low, operation and maintenance cost is few air pulsing powder material device for discharging is provided.It utilizes pressurized air, make to be positioned near the powder uniform pulse inflation of container unloading valve, and make it produce slightly rotation, thereby make near the powder material this place there is good flowing power, reduce the friction coefficient of this place's powder material and container inner wall simultaneously, guarantee that powder material is by the smooth and easy discharging of device for discharging.
The technical scheme that realizes above-mentioned purpose is: a kind of air pulsing powder device for discharging, it comprises the powder material warehouse of bottom with the circular cone bucket, the lower end of this powder material warehouse connects a disc for air inflation by a flange, the discharge hopper of following connection one cone shape of this disc for air inflation, the lower end of this discharge hopper is equipped with blow-off valve; The upper disk surface of described disc for air inflation is provided with circumferential groove, be provided with the air inlet through hole be communicated with described circumferential groove below this disc for air inflation, be evenly distributed with the air discharge duct be communicated with this circumferential groove in the inboard of described circumferential groove, the radially angle α of each air discharge duct is 30 ° ~ 45 °.
The technical solution of the utility model also comprises: between the lower card of the upper disk surface of described disc for air inflation and described flange, be provided with seal gasket.
The utility model can be realized quick and smooth powder material discharging operation.It has overcome the defect of original technology, for the powder of poor fluidity, can guarantee that discharging is smooth and easy.Simultaneously it has simple in structure, cost of manufacture and over-the-road expense is low, working stability failure-free advantage.
The accompanying drawing explanation
Fig. 1 is this air pulsing powder device for discharging structural representation.
Fig. 2 is the disc for air inflation structural representation of this air pulsing powder device for discharging.
The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, this air pulsing powder device for discharging comprises the powder material warehouse 1 of bottom with the circular cone bucket, the lower end of powder material warehouse 1 connects a disc for air inflation 3 by a flange 2, the discharge hopper 4 of following connection one cone shape of disc for air inflation 3, a blow-off valve 5 is assembled in the lower end of discharge hopper 4, between the lower card of the upper disk surface of disc for air inflation 3 and flange 2, is provided with seal gasket 6.The upper disk surface of disc for air inflation 3 is provided with circumferential groove 7, is provided with the air inlet through hole 8 be communicated with circumferential groove 7 below disc for air inflation 3, and air inlet through hole 8 communicates with external air source.Be evenly distributed with the air discharge duct 9 be communicated with circumferential groove in the inboard of circumferential groove 7, the radially angle α of each air discharge duct 9 is 30 ° ~ 45 °.
As accompanying drawing 2 embodiment, the circumferential groove 7 above disc for air inflation 3 can be arranged to the arc groove that a plurality of radiuses are identical, and each arc groove is uniformly distributed on circumference, and the bottom of each arc groove one end arranges an air inlet through hole 8.
Principle of work of the present utility model is described as follows:
When the powder material warehouse 1 that powder material is housed needs the discharging operation, compressed air control valve starts the pulse conducting, pure air enters in the circumferential groove 7 of disc for air inflation 3 through control cock with the form of pulse by air inlet through hole 8, then, gas is again through each air discharge duct 9 ejections, form the pulse screw air-flow, this pulse screw air-flow is constantly inflated and is made it to produce unitary rotation trend to powder material inside, after the gas of powder material inside is increased to certain value, distance between powder particle increases, the cubic expansion of powder, the internal friction coefficient of powder descends, the friction coefficient of powder and container inner wall reduces simultaneously, now open blow-off valve 5, the smooth and easy outflow under the effect of gravity of sufficient powder material is inflated in the container bottom.After the sufficient powder of inflation flows out, its top is inflated inadequate powder and also can be followed and drop near disc for air inflation 3, and at this moment disc for air inflation 3 is inflated and twisted it again, makes its smooth and easy outflow.Disc for air inflation 3 constantly produces the pulse swirling eddy in whole discharge process, finally completes whole discharging operation.
