Abstract
The invention discloses a spiral filter net which comprises a columnar filter net, wherein meshes are uniformly formed in the side wall of the cylindrical filter net, and a spiral stirrup for enhancing the strength of the filter net is arranged on the side wall of the cylindrical filter net. The spiral filter net is characterized in that a plurality of open pores capable of filtering impurities are formed in the spiral stirrup. Firstly, the spiral stirrup is arranged on the filter net so that the strength of the filter net can be greatly improved, the filter net does not deform; in addition, the open pores are formed in the spiral stirrup, and play a filtering role through the meshes in the filter net so that the impurities are filtered, and the purpose of ensuring the filtering effect and speed while the strength of the filter net is enhanced is achieved.
Description
Technical field
The present invention relates to a kind of spiral screen pack.
Background technology
Screen pack, is called for short filter screen, is that the woven wire by different meshes processes, and its effect is filtering molten material stream and increases material flow resistance, so as to elimination mechanical admixture with improve effect mixing or plasticizing, has acidproof, alkaline-resisting, heatproof, the performance such as wear-resisting.Because the template of screen pack is thin and mesh is overstocked, screen pack ubiquity structural strength is in the market low, yielding problem.In order to increase the intensity of screen pack, generally adopt the intensity that spiral stirrup increases screen pack is set on screen pack, the width of stirrup is wider, the intensity of screen pack is stronger, but along with the width of stirrup increases, the filter effect of screen pack is slowed down, and stirrup can stop filter effect and the speed of screen pack.
Summary of the invention
For the problems referred to above, the invention provides a kind of spiral screen pack, when increasing screen pack intensity, guarantee effect and the speed of filtering.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
Spiral screen pack, comprise cylindrical screen pack, on the sidewall of cylindrical screen pack, be evenly provided with mesh, on the sidewall of cylindrical screen pack, be provided with the tie hoop that increases screen pack intensity, it is characterized in that, on described tie hoop, be provided with the perforate that several can impurity screening.
First the intensity that tie hoop can improve screen pack is greatly set on screen pack, make it not yielding, perforate is set in addition on tie hoop, the filtration of these perforates playing with the mesh on screen pack, filter out impurity, reached and when increasing screen pack intensity, guaranteed the effect of filtration and the object of speed.
Further, the thickness of described tie hoop be cylindrical screen pack sidewall thickness 1-3 doubly.Thickness is thicker, and the intensity of screen pack is higher.
Further, the width of described tie hoop be distance between adjacent two mesh 0.5-2 doubly.Width is wider, and the intensity of screen pack is higher.
The invention has the beneficial effects as follows: spiral screen pack guarantees effect and the speed of filtering, the Stability Analysis of Structures of screen pack, durable in use when increasing screen pack intensity.
Accompanying drawing explanation
Fig. 1 is the spiral screen pack of existing design;
Fig. 2 is spiral screen pack of the present invention;
The mark implication of accompanying drawing is as follows:
1: cylindrical screen pack; 2: sidewall; 21: mesh; 3: tie hoop; 31: perforate.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, so that those skilled in the art can better understand the present invention also, can be implemented, but illustrated embodiment is not as a limitation of the invention.
As shown in Figure 1, be the spiral screen pack of existing design, can easily see, the mesh of cylindrical screen pack compares comparatively dense, the intensity of cylindrical screen pack is very weak, be easy to distortion, in order to increase the intensity of cylindrical screen pack, on sidewall, be provided with tie hoop, but tie hoop is solid, width increase along with tie hoop, slows down the filter effect of screen pack, and solid spiral hoop influential point of tendons stops filter effect and the speed of screen pack.
Fig. 2 is spiral screen pack of the present invention, comprise cylindrical screen pack, on the sidewall of cylindrical screen pack, be evenly provided with mesh, on the sidewall of cylindrical screen pack, be provided with the tie hoop that increases screen pack intensity, on tie hoop, be provided with the perforate that several can impurity screening.Tie hoop is not solid.First the intensity that tie hoop can improve screen pack is greatly set on screen pack, make it not yielding, perforate is set in addition on tie hoop, the filtration of these perforates playing with the mesh on screen pack, filter out impurity, reached and when increasing screen pack intensity, guaranteed the effect of filtration and the object of speed.The thickness of tie hoop should be not less than the thickness of sidewall, and the thickness of preferred tie hoop is 1-3 times of cylindrical screen pack sidewall thickness.Thickness is thicker, and the intensity of screen pack is higher.In order to guarantee that same thickness reaches the best effect of gaining in strength, the thickness that tie hoop exceeds outside in cylindrical screen pack sidewall should equate, that is to say, tie hoop exceeds the thickness of sidewall outside on thickness direction, equates with the thickness that exceeds interior.Same, the width of tie hoop is wider, and the intensity of screen pack is higher.The width of preferred tie hoop is 0.5-2 times of distance between adjacent two mesh.
These are only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
