Abstract

The utility model provides a plastic grain vibration screen, comprising feeding openings, a bracket, a screen, and a discharging opening. The plastic grain vibration screen is characterized in that at least two feeding openings are arranged; the screen is divided into two layers; a first layer of the screen is used for filtering large grains and strip-shaped grains, and a second layer of the screen is used for filtering thin and small grains and powder; and screens of the first layer and the second layer of the vibration screen are arranged in an inclined manner. According to the plastic grain vibration screen provided by the utility model, multi-path feeding is used, so that the thickness of a material layer on the screen is reduced; the screen is sufficiently used; the unnecessary transportation distance of thick and large grains can be reduced; and the filtering efficiency of the screen of the first layer is improved. The screens are mounted in the inclined manner, so that the grain mobility is increased, and the filtering efficiency of the materials is improved.

Description

A kind of plastic grain vibratory sieve
Technical field
The utility model belongs to mechanical manufacturing field, relates to a kind of plastics-production equipment, is specifically related to a kind of vibratory sieve of plastic grain screening.
Background technology
Sieving machine be in the engineering to material by the special equipment that particle diameter carries out classification, obtained extensive use at plastic industry, the screening effect of vibratory sieve not only has very big influence to value of the product, and directly next step efficiency of operation is had material impact.And existing common vibratory sieve only is provided with a material inlet usually, apart from 1/3~1/2 screen cloth of exhaust end, except that a part of sieving actoion, also will play about the transportation of a part like this, has reduced the utilization rate of screen cloth, and screening efficiency is low; In addition, existing vibratory sieve is in the process that screens out tiny plastic cement pellet and powder, because illiquidity causes screening unclean easily, product quality reduces.
The utility model content
It is low that the utility model purpose solves existing bolting efficient exactly, and tiny plastic cement pellet and powder is difficult to screen clean problem simultaneously.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of plastic grain vibratory sieve comprises: material inlet, support, screen cloth, discharging opening is characterized in that: described material inlet has 2 at least; Said screen cloth is divided into two-layer, and ground floor filters bulky grain or rectangular particle, and the second layer filters fine particle and powder, and wherein the ground floor screen cloth of vibratory sieve and second layer screen cloth all tilt to place; Every layer of screen cloth of said vibratory sieve is provided with blow tank, is communicated with discharge hole for discharge; Fine particle and powder that said vibratory sieve second layer screen filtration goes out are provided with blow tank, are communicated with discharge hole for discharge.
Preferably, the angle that tilts between described ground floor screen cloth and second layer screen cloth and the horizontal plane is 8 °~17 °;
Preferably, described screen cloth material is rubber or polyurethane material;
The beneficial effect of the utility model is: through adopting the multichannel feed, reduced the thickness of feed layer that is given on the screen cloth, utilized screen cloth fully, reduced the unnecessary transportation distance of big particle, improved the filter efficiency of ground floor screen cloth; Ground floor screen cloth and the second layer screen cloth mounting means through tilting, the flowability of increment rate particle has improved the filter efficiency of material, effectively the quality of fraction downstream product.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure:
1 material inlet; 2 ground floor screen clothes;
3 second layer screen clothes; 4 ground floor screen cloth discharging openings;
5 second layer screen cloth discharging openings; 6 supports;
The filtrate discharging opening that 7 second layer screen filtrations go out.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
Embodiment
As shown in Figure 1, for a kind of plastic grain vibratory sieve of the utility model, comprising: material inlet 1; Ground floor screen cloth 2, second layer screen cloth 3, ground floor screen cloth discharging opening 4; Second layer screen cloth discharging opening 5, support 6, the filtrate discharging opening 7 that second layer screen filtration goes out; Wherein contain 2 material inlets 1 and two-layer screen cloth, wherein ground floor screen cloth 2 apertures are bigger, mainly filter bulky grain or rectangular particle; Tilt to place, and be 9 ° of angles between the horizontal plane, filter the back leftover materials and be communicated to discharging opening 4 dischargings through blow tank; Second layer screen cloth 3 filters fine particle and powder, tilts to place, and is 16 ° of angles between the horizontal plane, filters the back leftover materials and is communicated to discharging opening 5 dischargings through blow tank, and the filtrate that filters out is through discharging opening 7 dischargings; Whole vibrating screen device is supported by support 6, is placed horizontally at ground.

Claims (2)

1. plastic grain vibratory sieve, comprising: material inlet, support, screen cloth, discharging opening is characterized in that: described material inlet has 2 at least; Said screen cloth is divided into two-layer, and wherein the ground floor screen cloth of vibratory sieve and second layer screen cloth all tilt to place; Every layer of screen cloth of said vibratory sieve is provided with blow tank, is communicated with discharge hole for discharge; Fine particle and powder that said vibratory sieve second layer screen filtration goes out are provided with blow tank, are communicated with discharge hole for discharge.
