Abstract
The invention discloses a vibration screen. The vibration screen comprises a screen box, a vibrator installed in the screen box, an upper supporting device installed on the screen box and a transmission device. The screen box comprises a screen plate and screen cloth fixed to the screen plate, the screen plate is a toothed polyurethane screen plate and provided with a plurality of areas of the same size, a plurality of strip-shaped protrusions A and protrusions B are arranged in each area in the horizontal and vertical directions, and the distance between the protrusions A in the horizontal direction is equal to the distance between the protrusions B in the vertical direction. Holes A are arranged between every two protrusions A and every two protrusions B, a plurality of holes B are formed in the screen cloth, and the holes B correspond to the holes A in position. The toothed polyurethane screen plate is adopted. Therefore, the mass of the screen plate is reduced without affecting the performance of the screen plate, the screen plate can be replaced conveniently, and the noise during work of the vibrator is also lowered.
Description
Technical field
The present invention relates to powder screening field, especially a kind of vibratory sieve.
Background technology
Vibratory sieve utilizes vibrating motor exciting as vibration source, make material tossed on screen cloth, simultaneously moving linearly forward, material enters the charging aperture of screening machine equably from batcher, by multilayer screen cloth produce several specifications oversize, screenings, discharge from respective outlet respectively.The scope of application of vibratory sieve is very extensive, the every aspect almost related in life all needs to use various types of vibratory sieve when processing and manufacture, the replacement screen cloth of vibratory sieve owing to needing vibration meeting regular, cause work inconvenience, and inconvenient operation, simultaneously screen cloth layout is single, can not maximum using material screening during material screening.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of vibratory sieve, described vibratory sieve is provided with multiple tracks screen cloth composition, need not overallly replace when screen cloth is replaced, monolithic is only needed to replace, make simple to operate, angle along material movement direction by screen cloth and horizontal direction is reduced successively, the movement velocity of the material that can slow down simultaneously, material maximum using can be got up.
In order to solve the problem, technical scheme of the present invention is a kind of vibratory sieve, comprise support, and the screen box on support, vibrating mechanism in screen box, motor in screen box, screen cloth is provided with in described screen box, screen cloth connects vibrating mechanism, driven by motor vibrating mechanism vibrates, it is characterized in that, described screen slope is placed, and comprise first screen cloth, second screen cloth, tertiary screen net, described first screen cloth along the angle being angle in the horizontal direction with described first screen cloth on material movement direction be greater than described second screen cloth on material movement direction with the angle that described second screen cloth is angle in the horizontal direction, the angle that described second screen cloth is angle in the horizontal direction with described second screen cloth on material movement direction be greater than described tertiary screen net on material movement direction with the angle that described tertiary screen net is angle in the horizontal direction.
Further, described first screen cloth is 30 ° ~ 35 ° along the angle being angle in the horizontal direction with described first screen cloth on material movement direction.
Further, the angle that described second screen cloth is angle in the horizontal direction with described second screen cloth on material movement direction is 25 ° ~ 30 °.
Further, the angle that described tertiary screen net is angle in the horizontal direction with described tertiary screen net on material movement direction is 25 ° ~ 30 °.
Further, described tertiary screen net adopts Rubber screen.
Beneficial effect of the present invention: adopt tertiary screen net composition, can conveniently replace when wherein certain section of screen cloth goes wrong, angle along material movement direction by screen cloth and horizontal direction is reduced successively, the movement velocity of the material that can slow down simultaneously, material maximum using can be got up.

Detailed description of the invention
A kind of vibratory sieve, comprise support 1, and the screen box 2 on support 1, vibrating mechanism 3 in screen box 2, motor 4 in screen box 2, screen cloth 21 is provided with in screen box 2, screen cloth 21 connects vibrating mechanism 3, motor 4 drives vibrating mechanism 3 to vibrate, screen cloth 21 slant setting, and comprise first screen cloth 211, second screen cloth 212, tertiary screen net 213, first screen cloth 211 along the angle with first screen cloth 211 being angle on material movement direction be in the horizontal direction greater than second screen cloth 212 on material movement direction with the angle that second screen cloth 212 is angle in the horizontal direction, second screen cloth 212 is that the angle of angle is greater than the angle that tertiary screen net 213 is angle in the horizontal direction with tertiary screen net 213 on material movement direction in the horizontal direction with second screen cloth 212 on material movement direction, in the course of the work, adopt tertiary screen net composition, can conveniently replace when wherein certain section of screen cloth goes wrong, make replacement more convenient.
Even in order to ensure the movement velocity of material, be 30 ° ~ 35 ° by first screen cloth 211 along being the angle of angle in the horizontal direction with first screen cloth 211 on material movement direction, second screen cloth 212 is the angle of angle in the horizontal direction with second screen cloth 212 on material movement direction is 25 ° ~ 30 °, the angle by tertiary screen net 213 with tertiary screen net 213 being angle on material movement direction is in the horizontal direction 25 ° ~ 30 °, adopts said structure the angle along material movement direction by screen cloth and horizontal direction to be subtracted successively.Little, the movement velocity of the material that can slow down, can get up material maximum using.
Tertiary screen net is adopted Rubber screen, screen cloth overall weight is reduced, screen cloth elastic force can increase well the jumping frequency rate of material simultaneously, improving screening efficiency, also increasing various different framework material in mould pressing process, can increase the service life.
Above one embodiment of the present of invention have been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalizations done according to the invention application range change and improve, and still all should belong to patent covering scope of the present invention.
