Abstract
The utility model belongs to the technical field of the filter, especially, relate to a spectacle plate protection extruder filtration system, its characterized in that includes the filter fixed plate that links to each other with the extruder, sets up crossing filter plate and setting up in the having the filter screen protection orifice plate I of perforating hole and have the filter screen protection orifice plate II of perforating hole of fixed plate both sides in the filter fixed plate, crisscross setting of perforating hole on perforating hole on the filter screen protection orifice plate I and the filter screen protection orifice plate II. The utility model discloses an advantage: because the sizing material of extruder after leaving the thread groove, directly gets into the in -process of perforated plate II, under the effect of intensive perforating hole, with powerful sharp pressure with because of the produced torsion of the rotary motion of sizing material decomposes, the thrust and the velocity of flow that make whole flow direction receive keep even unanimity as far as possible. The speed on the surface and the pressure of the filter screen of the flow (filtration stage) of sizing material in extruder head are comparatively even like this, and reduce the impact force of sizing material to the filter screen.
Description
Technical field
The invention belongs to filter technology field, more particularly, to a kind of spectacle plate protection formula extruder filtration system.
Background technology
Extruder/extruder is the capital equipment in rubber and plastic products production technology.Extruder is so that material is passed through
Effect between extruder barrel wall and screw rod, is continuously manufactured by into the various difference semi-finished product of present situation or the technique mistake of finished product
Journey.Extruder extrudes principle：1. material puts into the feeding stage；2. plasticizing compression stage in extruder for the material；3. material exists
Motion state flowing stage in Extrusion；4. flow regime filtration stage in cross-head for the material；5. material exists
Flow regime in the extruder shape of the mouth as one speaks goes out the type stage.
Extruder filtration system, is in the production process of rubber or plastic extruding forming, is used for preventing from going out in the middle of material
Existing impurity enters in the shaped article of extrusion, causes defective work or the waste product of product.
The type of the filtration system of existing extruder is as protection board by fixing porous plate, adds screen pack and consolidates
Determine what ring was formed.The specification of screen pack（Mesh number）Being credit rating according to product requirement to determine, higher grade, filters
The mesh number of net is higher.
During rubber extruding product, when just starting, in the case that screen pack is clean, sizing material is produced by screen pack
Extruding force less, and be gradually increased, with the amount of impurities in institute's trapped material above screen pack, the sieve blocking screen pack
Hole.So in the case that the flowing velocity of sizing material is constant, the pressure filtering on net surface is gradually increased.And what screen pack used
The pressure that bearing steel wires are subject to is limited, and the mesh number of screen pack is bigger, and the pressure that steel wire more carefully bears is less.If screen pack is subject to
The steel wire of pressure bearing not screen pack will rupture, and causes the screen pack to start a leak.And the appearance with leak, the stream of sizing material
Dynamic speed increases, and what other local sizing materials also can be concentrated goes to the fast local motion of flow velocity, therefore promotes leak constantly to expand
Greatly, filtration system is caused to lose efficacy.
Content of the invention
For solving drawbacks described above present in prior art, it is an object of the invention to provide a kind of spectacle plate protection formula extrusion
Machine filtration system, this filtration system has little to screen pack pressure oscillation in extrusion, little impact on production, can have simultaneously
Effect ground extends the service life of screen pack.
The purpose of this utility model is realized by following technical proposals：
Spectacle plate protection formula extruder filtration system of the present utility model is it is characterised in that include the mistake being connected with extruder
Filter fixed plate, the screen pack being arranged in filter fixing plate and the mistake with through hole being arranged on screen pack both sides
Filter screen protects orifice plate I and the screen pack with through hole to protect orifice plate II, and screen pack protects through hole and screen pack on orifice plate I
Through hole on protection orifice plate II is crisscross arranged.
Between described screen pack protection orifice plate II and screen pack apart from h be 2-3 millimeter.
Advantage of the present utility model：
Because the sizing material of extruder is after leaving thread groove, during being directly entered porous plate II, in intensive insertion
In the presence of hole, by powerful straight line pressure with because torsion produced by the rotary motion of material is decomposed, make entirely to flow
The thrust that dynamic direction is subject to and flow velocity keep uniformity as far as possible.So flowing in cross-head for the sizing material（Filter rank
Section）The surface of screen pack on speed and pressure more uniform, and reduce the impulsive force to screen pack for the sizing material, effectively extended
The service life of filter screen.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Further illustrate specific embodiment of the present utility model below in conjunction with the accompanying drawings.
As shown in figure 1, spectacle plate protection formula extruder filtration system of the present utility model is it is characterised in that including and extruding
The filter fixing plate 1 that machine is connected, the screen pack 2 being arranged in filter fixing plate 1 and be arranged on screen pack 2 both sides
Screen pack with through hole protects orifice plate I 3 and the screen pack with through hole to protect orifice plate II 4, and screen pack protects orifice plate I 3
On through hole and screen pack protect the through hole on orifice plate II 4 to be crisscross arranged.
In figure arrow direction is material Extrusion Flow direction.
Because the utility model has additional one to reduce this phenomenon, root as far as possible in sizing material Extrusion Flow direction side
According to rubber and plastic material in extruder within motion state and liquid form principle, increased band on the basis of original
The screen pack having through hole protects orifice plate II 4, and sizing material, after leaving thread groove, is directly entered the screen pack protection with through hole
In orifice plate II 4, in the presence of intensive aperture, by powerful straight line pressure with because of torsion produced by the rotary motion of material
Decomposed, make thrust that whole flow direction is subject to and flow velocity keep uniformity as far as possible.So material is in extruder
Flowing in head（Filtration stage）The surface of screen pack on make the speed of material and pressure could more uniformity, thus
Give the passage of the multiple fixation of sizing material, thus reducing the impulsive force to screen pack for the sizing material.
Protecting distance between orifice plate II 4 and screen pack 2 additionally, due to screen pack described in the utility model is 2-3 millimeter.
In figure shows that between screen pack protection orifice plate II 4 and screen pack 2, distance is 2 millimeters, and this slight space is in extruder
Formed adverse current when the impurity in sizing material is brought into toward contrary direction, here it is impurity meet obstructions after rebound phenomena.But
The strength of following current is far longer than the strength of adverse current, and the impurity that bounce-back is constantly returned by the sizing material of following current shifts screen pack again onto
The impurity in direction, therefore sizing material just can constantly be stacked into above screen pack, results in blockage.Therefore this slight space is exactly can
Enough make the sizing material of following current that the impurity " purging " returned that rebounds is not subject to the place of impulsive force to screen pack（The gap of porous plate
Or edge）, the impurity of therefore sizing material will not be stacked into above screen pack in large area, results in blockage, because sizing material has admittedly
Fixed passage, thus reduce the squeezed possibility springing a leak of screen pack, thus ensureing the weight performance of material extrusion.
