Description
Technical field
The invention belongs to a kind of filter element of band filter, relate in particular to a kind of for the compound strainer of strong suction on the filter.
Background technology
The strainer that existing band filter is used, concrete structure are the reticular zones of monofilament polyester knitting forming, and its purposes is the suspension in the liquid to be leached drain, its advantage is the hot strength height, its shortcoming, and the one, the strainer mesh is big, between the 0.5-0.8 millimeter of aperture, during press dewatering, pressure is less than 0.3mpa, when pressure is big slightly, easily saturating filter, flash, filtering accuracy is low, and the suspension in the filtrate still has 0.1%-1%, requirement height to flocculant, secondly the production cost height is that polyester moulding guipure does not have water imbibition, when dehydrated material enters pressed zone, water in the material is squeezed out, and when dehydrated material broke away from pressed zone, the water that adheres on the strainer can be sucked by material again, especially serious when particularly squeezing organic materials, so the material water ratio height, moisture content to 82% when the highest, the 3rd,, partial material can stick on the strainer, incrust, need a large amount of one meter wide strainers of clear water flushing, water consumption needs 6-8m
3/ hm has caused secondary pollution, and existing strong suction gathers ethanol (pva) sponge material in addition, as the Separation of Solid and Liquid medium, though the water absorbing properties excellence, the filtering accuracy height, hot strength is low, and only being suitable for two or three months in the commercial Application just need replacing.
Summary of the invention
The low compound strainer of strong suction of a kind of filtering accuracy height, hot strength height, water consumption that the objective of the invention is to overcome the deficiencies in the prior art and provide.
The present invention is achieved in that
A kind of for the compound strainer of strong suction on the filter, comprise the strainer body, it is characterized in that: described strainer body is made of a plurality of strainer sheet materials, described strainer sheet material is made of polyester webs and water-absorbing sponge, polyester webs is the mesh sheets structure, and be embedded in the water-absorbing sponge, the last wire side of polyester webs all is implanted with hair with following wire side.
Expose from water-absorbing sponge at described polyester webs sheet material two ends, and exposed portions serve is rolled the formation ring joint.
The material of described hair is polyester fiber.
The material of described water-absorbing sponge is polyvinyl alcohol.
The ring joint butt joint of described each strainer sheet material, and penetrate the plastics silk, form the strainer body.
The present invention has drawn the advantage of existing strainer and existing strong water-absorbing sponge sheet material, has avoided the defective of the two again, its filtering accuracy height, interception suspension particle diameter is less than 10 microns, and filtrate is limpid, and is big to the squeeze pressure of material, can reach 3mpa, the water of squeezing out is sucked by water-absorbing sponge immediately, and can not sucked again by material, and material water ratio is less than 65%, by compound strainer aperture less than 10 microns, smooth surface, material easily peels off, and flushing strainer water consumption is less than 2m
3/ hm, the hot strength of the compound strainer that absorbs water by force reaches 1600N/cm, strength of joint 650N/cm.

The specific embodiment
Embodiment 1: as shown in Figure 1, a kind of for the compound strainer of strong suction on the filter, comprise the strainer body, it is characterized in that: described strainer body is made of a plurality of strainer sheet materials, described strainer sheet material is made of polyester webs 11 and water-absorbing sponge 10, polyester webs 11 is the mesh sheets structure, and be embedded in the water-absorbing sponge 10, the last wire side of polyester webs 11 all is implanted with hair 12 with following wire side, and expose from water-absorbing sponge 10 at polyester webs 11 sheet material two ends, and exposed portions serve is rolled and formed ring joint 9, the material of hair 12 is polyester fiber, the material of water-absorbing sponge 10 is polyvinyl alcohol, needs before using the strainer installation is combined, with ring joint 9 alignment of two strainer sheet materials, ring joint 9 penetrates the plastics silk, so operation forms the strainer body, and is installed on the filter; In the course of work, the water of squeezing out is inhaled 10 by water-absorbing sponge immediately and is gone into, polyester webs 11 is embedded in the water-absorbing sponge 10, increased the hot strength of water-absorbing sponge 10, hair 12 makes the more firm of polyester webs 11 and water-absorbing sponge 10 combinations, and specifically: the principle of planting hair 12 at polyester webs 11 has been equivalent to increase the contact area of polyester webs 11 with water-absorbing sponge 10.
The application of strong suction strainer, the process of its suction dehydration is as follows:
The material that the step 1) charging aperture is 4 li is evenly distributed on the lower filter belt 7 because of gravity fall;
Step 2) material arrives gravity dehydration district 2 with lower filter belt 7, and in gravity dehydration district 2, water a large amount of in the material are sucked by lower filter belt 7, and material water ratio is down to 90% once;
Step 3) material then enters wedge shape drying zone 3, and last strainer 6 and lower filter belt 7 clampings material and further dewatered, and at this moment, material loses flowability substantially;
The step 4) material enters pressurizing and dehydrating district 1 under the clamping of last strainer 6 and lower filter belt 7, be 8 squeezings by backer roll, and material is step dehydration again;
Specifically: in whole pressurizing and dehydrating process, because the suction of strainer, water separation capability be considerably beyond suction, the water separation capability of material self, the moisture content that is squeezed out in the material only can be sucked by strainer, and can not sucked by material again;
Step 5) enters discharge zone, and the material that is drained is scraped from strainer by wing, pulls storage bin hopper 5 into, finishes the squeezing operation.
The present invention has drawn the advantage of existing strainer and existing strong water-absorbing sponge sheet material, has avoided the defective of the two again, its filtering accuracy height, interception suspension particle diameter is less than 10 microns, and filtrate is limpid, and is big to the squeeze pressure of material, can reach 3mpa, the water of squeezing out is sucked by water-absorbing sponge immediately, and can not sucked again by material, and material water ratio is less than 65%, by compound strainer aperture less than 10 microns, smooth surface, material easily peels off, and flushing strainer water consumption is less than 2m
3/ hm, the hot strength of the compound strainer that absorbs water by force reaches 1600N/cm, strength of joint 650N/cm.
