Abstract
The invention provides an industrial screen, in particular to a technical proposal of an erect impact screen; the technical proposal includes a feeding port and a box including a discharge hole of plus mesh and a discharge hole of undersieves, and sieve plates are arranged in the box; the proposal is that: at least two impact screen separation units are vertically arranged in the box in an up and down way; the impact screen separation units are provided with distributors, the tops of the cross sections of which take a conical shape, at the position of the central lateral plane of the box from top to bottom, two sieve plates, which are symmetrical by taking the central lateral plane of the box as an axle, are arranged at the two sides of the middle lower part in a V-shaped way, and two guide boards of the material under the screen, which are symmetrical by taking the central lateral plane of the box as an axle, are arranged at the lower parts of the two sieve plates in an inverted V-shaped way. The discharge hole of the plus mesh is the space between the impact screen separation units and the two guide boards of the material under the screen, and the discharge hole of the undersieves is the space between the two guide boards of the material under the screen and the side wall of the box.
Description
Affiliated technical field:
What the present invention relates to is a kind of industrial industry sieve that is used for sieving material, especially a kind of vertically-arranged impact screen.
Background technology:
In the prior art, technique known is that the applicant applies for and authorizes disclosed No. 200420097464.0 patents by State Intellectual Property Office, this patent disclosure a kind of technical scheme of vertical screen, be to incite somebody to action continuously arranged sieve plate up and down, make into to be staggered up and down, save the area that screening takies to reach, this structure, really when reaching identical screening effect, saved floor space again, but the effect to screening toughness material just seems very not enough, and this is the existing in prior technology weak point.
Summary of the invention:
Purpose of the present invention is exactly at the existing in prior technology deficiency, and provide a kind of vertically-arranged impact screen technical scheme, this scheme is formed the impact screen subdivision by tripper, two sieve plates and two minus mesh guide plates, the potential energy that utilizes material to fall separately impacts the both sides sieve plate by tripper with material and sieves, and this is very favourable to screening toughness material.
This programme is realized by following technical measures: comprise the casing that has charging aperture and discharging opening, sieve plate arranged in casing, the characteristics of this programme be in casing up and down arranged vertical have two impact screen subdivisions at least; Described impact screen subdivision is to have from top to bottom that in the position of casing central lateral plane the cross section top to be arranged be the tripper of taper, there are two to be axial symmetry in both sides, described tripper middle and lower part with the casing central lateral plane, and be the sieve plate that herringbone is arranged, there are two to be axial symmetry in the bottom of described two sieve plates, and are the minus mesh guide plate that splayed is arranged with the casing central lateral plane.The concrete characteristics of this programme also have, and described discharging opening has oversize discharging opening and minus mesh discharging opening.Described oversize discharging opening is the space between the two minus mesh guide plates of afterbody impact screen subdivision.Described minus mesh discharging opening is two minus mesh guide plates of afterbody impact screen subdivision and the space between the wall box.It is mouthful corresponding with tripper that described charging aperture has charging to lead in casing.On described casing, exciting source can be arranged.
The beneficial effect of this programme can learn according to the narration to such scheme because in this scheme, be in casing up and down arranged vertical have two impact screen subdivisions at least; Described impact screen subdivision is to have from top to bottom that in the position of casing central lateral plane the cross section top to be arranged be the tripper of taper, there are two to be axial symmetry in both sides, tripper middle and lower part with the casing central lateral plane, and be the sieve plate that herringbone is arranged, there are two to be axial symmetry in the bottom of two sieve plates, and are the minus mesh guide plate that splayed is arranged with the casing central lateral plane.This structure, the material that is sized enters into first impact screen subdivision by charging aperture, material is separated it by the tripper of first impact screen subdivision under the effect of gravity to both sides, and the sieve plate that impacts first impact screen subdivision both sides sieves, entering second impact screen subdivision through the oversize of first impact screen subdivision screening sieves once more, this screening is to be sized material to impact on the sieve plate and sieve, and is just fairly obvious to the screening effect of toughness material.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure schematic diagram of the specific embodiment of the invention.
1 is casing among the figure, and 2 for the minus mesh guide plate, and 3 be sieve plate, and 4 is tripper, and 5 is charging aperture, and 6 lead mouth for charging, and 7 is exciting source, and 8 is the minus mesh discharging opening, and 9 is the oversize discharging opening.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the vertically-arranged impact screen of this programme, band charging aperture 5 is arranged and comprise the casing 1 of oversize discharging opening 9 with minus mesh discharging opening 8, arranged vertical has two impact screen subdivisions at least up and down in casing 1, and this specific embodiment has adopted three impact screen subdivisions.Described impact screen subdivision is to be arranged with from top to bottom that in the position of casing 1 central lateral plane the cross section top to be arranged be the tripper 4 of taper, there are two to be axial symmetry in both sides, described tripper 4 middle and lower part with casing 1 central lateral plane, and be the sieve plate 3 that herringbone is arranged, there are two to be axial symmetry in the bottom of described two sieve plates 3, and are the minus mesh guide plate 2 that splayed is arranged with casing 1 central lateral plane.Described oversize discharging opening 9 is the spaces between the two minus mesh guide plates 2 of afterbody impact screen subdivision; And described minus mesh discharging opening 8 is two minus mesh guide plates 2 of afterbody impact screen subdivision and the space between casing 1 sidewall.It is mouthfuls 6 corresponding with tripper 4 that described charging aperture 5 has charging to lead in casing 1.What described sieve plate 3 adopted in this specific embodiment is vibratory sieve.In addition, on described casing 1, exciting source 7 can be arranged, can certainly be without exciting source 7.
