The specific embodiment
Embodiment 1:
As shown in Figure 3, Figure 4, in the present embodiment, the aspiration-type hopper that is applicable to granule materials mainly comprises a cylindrical shell, and cylindrical shell is comprised of container body 1 and lid 2, and between the two by sealing member and hinge arrangement, realization can be opened or the structural relation of seal closure.
In the present embodiment, lid 2 adopts the material identical with container body 1, when its height is 1:2 with diameter ratio, can obtain the working effect of the best.
In the present embodiment, also be provided with negative pressure tracheae 21 on the lid 2, negative pressure tracheae 21 is positioned at the center of lid 2, is communicated with external depression generator (such as vacuum pump etc., not shown), to produce negative pressure in the cavity volume of container body 1.Be provided with feed pipe 11 on the container body 1, feed pipe 11 and external material source (such as comminutor etc., not shown) be communicated with.
Especially, in the utility model, feed pipe 11 is arranged on the tangential direction of container body 1 sidewall as good.The height of feed pipe 11 is positioned at the below of negative pressure tracheae 21.
In addition, also be provided with a back-up ring 3 in the cylindrical shell, the position of back-up ring 3 is in the negative-pressure air-flow passage between negative pressure tracheae 21 and the feed pipe 11 between container body 1 and lid 2.
Such as Fig. 5, shown in Figure 6, further, in the present embodiment, back-up ring 3 is funnel-form, has the wide mouth 31 towards container body 1 top, reaches the slot 32 towards container body 1 below, also can as shown in Figure 6, increase by a guiding circle at slot 32 places.
Principle of work of the present utility model is: because negative pressure tracheae 21 is positioned at the top of feed pipe 11, after external depression generator was opened, negative-pressure air-flow was from bottom to top by arrow B flow arrows A at inner barrel flow direction generally.
Granule materials from the material source is blended in the negative-pressure gas, is drawn into container body 1 along feed pipe 11.Because the position that feed pipe 11 arranges is in the sidewall tangential direction of container body 1, therefore, granule materials has a centnifugal force after leaving feed pipe 11, is not having in the situation of other External Force Actings, should be along the inwall rotational flow of container body 1.
Because negative-pressure air-flow generally flow direction in cylindrical shell is from bottom to top, therefore granule materials there is a upwards application force.In this simultaneously, act on the granule materials centnifugal force the self gravitation with granule materials form make a concerted effort after, be enough to offset above-mentioned upwards application force dropped in the cylindrical shell so that granule materials drops.In addition, because the position between negative pressure tracheae 21 and feed pipe 11 also is provided with the back-up ring of aforementioned structure, changed the flow trace of negative-pressure gas, after making negative-pressure gas in cylindrical shell, have an elder generation downwards on circuitous flowing, more be conducive to reduce negative-pressure gas and act on application force on the granule materials.
As shown in Figure 7, further, the aspiration-type hopper that is applicable to granule materials of the present utility model also comprises a baffle plate 4, and the cylinder 5 of control baffle plate 4 foldings.Baffle plate 4 shown in Figure 7 is turning structure (for example bar linkage structure), is driven by cylinder 5, when baffle plate 4 is among Fig. 7 solid line position, is in the state of a unlatching between the outlet of baffle plate 4 and cylindrical shell.When baffle plate 4 is among Fig. 7 dotted line position, be in the state of a closure between the outlet of baffle plate 4 and cylindrical shell.
The baffle plate of automatic control is set, is conducive to improve the degree of automation of the aspiration-type hopper that is applicable to granule materials.
In other embodiments, lid 2 and the container body 1 of cylindrical shell also can be reduced to integrative-structure, and in the course of processing back-up ring 3 are fixed on inner barrel by modes such as welding.
Embodiment 2:
Such as Fig. 8, shown in Figure 9, another embodiment of the present utility model, basic identical with the structure of above-described embodiment, difference is, negative pressure tracheae 21 is arranged on the tangential direction of lid 2 sidewalls, especially, the air inlet openings place of negative pressure tracheae 21 is towards the sense of motion of container body 1 endoparticle material, granule materials from air inlet pipe 11 along B after enter container body 1, by the effect of inertia of centnifugal force, inwall around container body 1 moves in a circle, and final negative-pressure gas is from negative pressure tracheae 21 along A to discharge, and granule materials is trapped in the container body 1.
Another difference of present embodiment is that back-up ring 3 is hollow cylindrical, has simple structure, can change equally the flow trace of negative-pressure gas in container body 1, makes negative-pressure gas circuitous flowing in cylindrical shell.
In other embodiments, back-up ring also can have towards the slot of cylindrical shell top and the wide mouth below cylindrical shell for falling funnel-form, can realize essentially identical technique effect.
As shown in figure 10, in the present embodiment, baffle plate 4 is Collapsible structure, is driven by the piston arm of cylinder 5, can change between the state of the state of a unlatching or a closure between 1 outlet of baffle plate 4 and container body.
Embodiment 3:
In the present embodiment, different from above-described embodiment is that further, the aspiration-type hopper that is applicable to granule materials also comprises a shunt valve, is arranged on the cylindrical shell downside.Shunt valve is existing structure, and this paper is burdensome stating not.
Adopt the shunt valve structure, be conducive to the outlet according to the granule materials in the different demand assignment cylindrical shell cavity volumes.
More than describe preferred embodiment of the present utility model in detail.The ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all in the art technical personnels are complied with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
