Abstract
The invention provides a method for screening materials in industry and an industrial sieve, in particular to an impact sieving method using energy of falling materials to be sieved and a technical proposal of an impact sieve. The technical proposal is as follows: a plurality of inclined and step-like screens are arranged up and down, and an impact board is arranged corresponding to an upper material outlet of each screen and above the next screen; the falling material to be sieved strikes a first screen to be sieved for the first time, the material is rebounded by the first screen, falls down to strike the impact board, then the material is reflected with the counteraction of the impact board and strikes the next screen to be sieved for the second time, and sieving of the material goes on like this. The impact sieve is characterized by the at least two screens in an inclined and step-like arrangement, and the material outlet on the sieve corresponding each screen, and the impact board which is arranged corresponding to the material outlet of each screen and above the next screen, and is fixed on a cross beam of a box body through a connecting rod.
Description
Affiliated technical field:
What the present invention relates to is a kind of industrial method for sieving and industry sieve that is used for sieving material, especially a kind of counterattack method for sieving and counterattack sieve that utilizes screening material drop energy.
Background technology:
In the prior art, it is known that what can sieve sticky material is Suspension arm sieve in usefulness, but Suspension arm sieve neither be specially at sticky material, therefore, unsatisfactory to the screening sticky material, and still not having a kind ofly so far to sticky material sieve ratio method for sieving and screening plant more effectively, 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, utilize the counterattack method for sieving of screening material drop energy and counterattack to sieve technical scheme and provide a kind of, this scheme adopts screen cloth to become the angled step formula to settle, in the oversize outlet of corresponding each screen cloth, there is counterpunch board the top of next screen cloth.Can utilize the energy that is sized the material whereabouts to hit screen cloth like this sieves, oversize rebounds to next screen cloth by counterpunch board again, and the screening downwards of one-level one-level ground is to hit on screen cloth owing to be sized material, just separated easily to sticky material, reach the purpose of screening effectively.
This programme is realized by following technical measures:
The characteristics of utilizing the counterattack method for sieving of screening material drop energy are that screen cloth a plurality of inclinations and that be arranged above and below by staged is arranged, and in the oversize outlet of corresponding each screen cloth, there is counterpunch board the top of next screen cloth; The screening material that falls hits and carries out screening first time on the first screen cloth, and material is hit on the counterpunch board by screen cloth downslides of upspringing, and is strikeed back by counterpunch board and carries out screening second time on next screen cloth, the downward screening like this.
The counterattack sieve includes support, support is connected with casing by shock absorber, charging aperture, oversize discharging opening, minus mesh discharging opening and vibration source are arranged on casing, screen cloth is arranged in casing, the characteristics of this programme are that described screen cloth has two at least, and become the angled step formula to settle, in the oversize outlet of corresponding each screen cloth, there is counterpunch board the top of next screen cloth, and this counterpunch board is fixed on the crossbeam of casing by connecting rod.The concrete characteristics of this programme also have, and described connecting rod is an elastic link.Bottom at described charging aperture also is connected with the charging chute.Described casing is the casing that tilts.
The beneficial effect of this programme can learn that owing in this scheme, adopt screen cloth to become the angled step formula to settle, in the oversize outlet of corresponding each screen cloth, there is counterpunch board the top of next screen cloth according to the narration to such scheme.Can utilize the energy that is sized the material whereabouts to hit screen cloth like this and sieve, the oversize that glides after first screen cloth sieves rebounds by counterpunch board and sieves to next screen cloth, so sieves downwards to the one-level one-level.Owing to be sized material is to hit on screen cloth, and sticky material is helped screening with regard to disperseing easily, reaches the purpose that can effectively sieve sticky material, has remedied the deficiencies in the prior art.This shows that the present invention compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the specific embodiment of the invention.
Among the figure, 1 is the oversize discharging opening, and 2 is support, and 3 is casing, and 4 is vibration source, and 5 is shock absorber, and 6 is counterpunch board, and 7 is connecting rod, and 8 is crossbeam, and 9 is charging aperture, and 10 are the charging chute, and 11 is screen cloth, and 12 are the minus mesh discharging opening.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, the utilization of this programme is sieved the counterattack method for sieving and the counterattack sieve of material drop energy and set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the described counterattack sieve of this programme has support 2, this support 2 is connected with the casing 3 that tilts by shock absorber 5, following charging aperture 9, oversize discharging opening 1, minus mesh discharging opening 12 and the vibration source 4 that connects charging chute 10 arranged on casing 3, screen cloth 11 is arranged in casing 3, the described screen cloth 11 of this programme is Flexible sieves 11 and has two at least that what this specific embodiment adopted is three screen clothes 11.11 one-tenth angled step formulas of described each screen cloth are settled, and in the oversize outlet of corresponding each screen cloth 11, there is counterpunch board 6 top of next screen cloth 11, and this counterpunch board 6 is fixed on the crossbeam 8 of casing 3 by rubber-like connecting rod 7.This just can utilize and be sized the energy strike screen cloth 11 that material falls, and the oversize that glides after first screen cloth 11 screenings passes through counterpunch board 6 bounce-backs again to next screen cloth 11, so downward screening in one-level one-level ground.Owing to be sized material is to hit on screen cloth 11, and sticky material is helped screening with regard to disperseing easily, reaches the purpose that can effectively sieve sticky material.
