Abstract

The utility model relates to a high molecular material sieve plate used for sieving raw materials. Strut rails (7) are fixed on the deck base (1) of the sieve plate from back to front in turn. Comb type grizzly bars are fixed on the strut rails (7). The comb dents (2) of the comb type grizzly bars (8) are in the direction of front. The tail plate (20) of each comb type grizzly bar is fixed on the strut rail. The front ends of the comb dents are freely hung above the tail plate (20) of the previous comb type grizzly bar. The length of the comb dents of each comb type grizzly bar is not less than the (65%)of the fore-and-aft width dimension of the entire comb type grizzly bar. The elasticity of the comb dents is largely enhanced because the length of the comb dents of the comb type grizzly bar is extended to more than (65%) of the width of the entire comb type grizzly bar. Material particles can shake up and down during a process of rolling front and rear when using. The material particles are not easy to jam between the comb dents so that the clogging of the materials can be largely eliminated. In addition, the amount of the strut rails can be reduced after the relative length of the comb dents is lengthened so that the entire weight of the sieve plate can be relieved, the self-weight of the utility model is decreased to a certain extent and the energy consumption of the utility model is reduced.

Description

A kind of macromolecular material sieve plate that is used for material screening
Technical field
The utility model relates to a kind of macromolecular material sieve plate that is used for material screening.
Background technology
In the use of sieve plate, usually cause the sieve plate cisco unity malfunction owing to the obstruction of sieve aperture, therefore, the anti-blocking performance of sieve plate is an important indicator of weighing sieve plate performance quality, in order to improve the anti-blocking performance of sieve plate, people are doing a large amount of work aspect the exploitation of sieve plate.Wherein, uses at present the comparatively successful stepped polyurethane sieve plate of broach that is, this sieve plate is made up of the mutual stepped polyurethane material grating that overlaps, and grating has the wide-open wedged hole of an end on the material movement direction.This fishback has serviceability preferably.But have certain shortcoming: at first, because the length of grating broach is shorter, and the tail-board length of perforate is not longer, causes the percent opening of sieve plate lower, has reduced the screening efficiency of sieve plate yet.The rigidity of broach is bigger simultaneously, elasticity is less, material movement in being stuck in sieve aperture to the overlap joint the position time, its top still is stuck on the sieve plate, but the back of another grating of overlap joint has been run in the bottom that sees through the material of sieve aperture, make material to see through sieve aperture by the strain of broach and realize saturating sieve, can not continue the disengaging sieve aperture that moves ahead again, stop up thereby produce.Because the percent opening of broach is low, broach is short, and required stull quantity is many, and in the use, the weight of whole sieve plate is bigger, and power requirement is bigger, the inconvenience of dismounting simultaneously; By the same token, whole comb shape grating will use more macromolecular material when making, and has improved manufacturing cost.
The utility model content
The purpose of this utility model is to provide a kind of macromolecular material sieve plate that is used for material screening, to solve problems such as foregoing obstruction, screening efficiency be low.
To achieve these goals, the technical solution of the utility model has been to adopt a kind of macromolecular material sieve plate that is used for material screening, be fixed with the steel stull from the back successively to preceding on the steel screen frame of sieve plate, be set with the comb shape grating of macromolecular material in each stull, the broach direction of comb shape grating forward, the tailgate partial fixing of each comb shape grating is in stull, the front end of broach freely is suspended in the tailgate top of last comb shape grating, and the length of the broach of each comb shape grating is not less than 65% of whole comb shape grating front and back width dimensions.
The length of the broach of each comb shape grating is preferably and is not less than 75% of whole comb shape grating front and back width dimensions.
Leading section lower surface at part or all of broach is provided with downward projection.
In broach from the leading section to the tailgate in combization be provided with the elasticity reinforcing bar, the cross section diameter of elasticity reinforcing bar is between 1-4mm.
The inner sulfuration of the tailgate of comb shape grating is provided with horizontal reinforcement steel plate.
Be provided with the gap between the tailgate of the top of projection and its below.
Sieve aperture between described broach and the broach is enlarging " U " shape profile.
In the middle of the broach fore-and-aft direction, laterally connect between the adjacent fingers.
In the middle of the broach lower surface downward projection 25 is arranged, adjacent fingers laterally connects by these projectioies.
Because the broach length of comb shape grating is extended to more than 65% of whole comb shape grating width, make the elasticity of broach increase greatly, during work, material particles is in the process of scroll forward and backward, can produce shake up and down, material particles is difficult for clamping stagnation between broach, has eliminated the clogging of material to a great extent.In addition, behind the relative length of the broach lengthening, can reduce the quantity of stull, the whole weight of sieve plate can alleviate, and can reduce deadweight to a certain extent, reduces the energy consumption of self; By the same token, can also reduce on the sieve plate consumption of macromolecular material in the comb shape grating manufacture process, reduce the manufacturing cost of sieve plate, after the elasticity reinforcing bar is set up in the inside of sliver, can improve the rigidity of broach effectively, prevent that the less macromolecular material broach of rigidity from producing bigger distortion, thereby can guarantee the shape of sieve aperture effectively, guarantee screening precision.Sieve tooth simultaneously and also be difficult for landing from the comb shape grating of front portion, help to guarantee the reliable and stable work of sieve plate.Front end at grating is provided with projection, can increase the gap of overlapping part, help material to sieve thoroughly, under the part broach projection is set, can make broach under the effect of material, produce different distortion, further improve anti-blocking permeability energy, simultaneously should projection under broach bears a heavy burden when curved, can work to arrive hook, stop the slippage of broach front end.Sulfuration elasticity reinforcing bar is set in the broach, can under the situation of broach lengthening, improves the rigidity of broach, prevent the excessive deformation of sieve aperture and influence screening precision, prevent the broach overbending simultaneously.Because broach is longer, so its rigidity is lower, the distortion about broach easily produces in the course of the work makes the sieve aperture distortion, influences screening precision.For this reason after laterally connecting between the adjacent fingers, thereby the precision that can guarantee sieve aperture effectively guarantees screening precision.The projection that laterally connects by the broach lower surface connects, and does not influence the percent opening of sieve plate on the one hand, also is not easy to produce putty on the other hand.
