Abstract
The utility model provides a video disc annular filter screen, include from last to down the first filter layer on the ring is established to the cover in proper order, first minute fluid layer, enhancement layer, second divide fluid layer and second filter layer, all are provided with circular fixed loop on first filter layer and the second filter layer, are provided with the radial preforming of several on the outer circumference of circular fixed loop that the outward flange that preforming, first filter layer, first minute fluid layer, enhancement layer, second divide fluid layer and second filter layer passes through welded connection and is in the same place. The utility model discloses an outside at two filter layers increases fixed loop and preforming to with the outer fringe welding of preforming and filter screen together, increased the intensity of whole filter screen, prolonged the life of filter screen.
Description
Technical field
The utility model relates to filter, particularly a kind of video disc annular filter screen being used for filtering optical film raw material impurity.
Background technology
In blooming industrial processes, occur brilliant point, be one of its modal quality problems.Brilliant point can affect the quality such as outward appearance, gluing of blooming, and in order to eliminate brilliant point and impurity, the main way adopted is filtered raw material when film production at present.The filter adopted in filter process is disc-type filter mainly, and the outer surface cover of filter core has multiple video disc annular filter screen, and filter core and video disc circular filter net are filtered raw material.But the filter course of video disc circular filter net is outside exposed, cause it to be very easily out of shape in hyperbaric environment, virtually add the use cost of enterprise.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide that a kind of intensity is large, the video disc annular filter screen of long service life.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of video disc annular filter screen, comprise annulus and be set in the first filter course, the first shunting layer, enhancement Layer, the second shunting layer and the second filter course on annulus from top to bottom successively, the corresponding described enhancement Layer place of inwall of described annulus is equidistantly provided with several conduction hole, described first filter course and the second filter course are provided with circular retainer ring, the excircle of described circular retainer ring is provided with several radial compressing tablet, and the outward flange of described compressing tablet, the first filter course, the first shunting layer, enhancement Layer, the second shunting layer and the second filter course is by being welded together.
Preferably, described retainer ring and described compressing tablet one-body molded.
Preferably, the excircle of described retainer ring is provided with eight radial compressing tablets, these eight compressing tablets make equidistant arrangement around the center of circle of described retainer ring.
Preferably, described first filter course and the second filter course are net double-face protective net sintering felt, and its filtering accuracy is 0.5 ~ 200 micron.
Preferably, described enhancement Layer is 8 orders, and wire diameter is the stainless (steel) wire of 1.5mm.
Pass through technique scheme, the video disc annular filter screen that the utility model provides, by increasing retainer ring and compressing tablet in the outside of two filter courses, and welds together the outer rim of compressing tablet and filter screen, add the intensity of whole screen pack, extend the service life of screen pack.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is the front view of a kind of video disc annular filter screen disclosed in the utility model embodiment;
Fig. 2 is the side cutaway view of a kind of video disc annular filter screen disclosed in the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As illustrated in fig. 1 and 2, a kind of video disc annular filter screen, comprise annulus 11 and be set in the first filter course 12 on annulus 11 from top to bottom successively, first shunting layer 13, enhancement Layer 14, second shunting layer 15 and the second filter course 16, enhancement Layer 14 is 8 orders, wire diameter is the stainless (steel) wire of 1.5mm, corresponding enhancement Layer 14 place of inwall of annulus 11 is equidistantly provided with several conduction hole 17, first filter course 12 and the second filter course 16 are provided with circular retainer ring 18, the excircle of circular retainer ring 18 is provided with eight radial compressing tablets 19, these eight compressing tablets 19 make equidistant arrangement around the center of circle of retainer ring, and retainer ring and compressing tablet one-body molded.The outward flange of compressing tablet 19, first filter course 12, first shunting layer 13, enhancement Layer 14, second shunting layer 15 and the second filter course 16 is by being welded together.
Wherein, the first filter course 12 and the second filter course 16 are net double-face protective net sintering felt, and its filtering accuracy is 40 microns.First shunting layer and the second shunting layer are porous plate, and its aperture is 1mm.
In use, on the filter core of filter, melt flows into from filter core by nestable for polylith annular filter screen, enters in enhancement Layer 14 from the conduction hole 17 of annulus 11, then is flow in filter course by shunting layer and filter.
In sum, the video disc annular filter screen that the utility model provides, by increasing retainer ring and compressing tablet in the outside of two filter courses, and welding together the outer rim of compressing tablet and filter screen, adding the intensity of whole screen pack, extending the service life of screen pack.
To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
