Abstract
The invention relates to a filter cloth bag for filtration of a filter press, which does not produce folds or biological accumulation, does not affect the formation of filter cakes in a filter chamber and has low feeding resistance and high work efficiency. The filter cloth bag for the filtration of the filter press comprises a filter cloth bag; a flange elastic sleeve made of high polymer material with elasticity is sleeved in the middle of the filter cloth bag and can be folded randomly, and a feeding hole sleeve of the flange elastic sleeve is tightly attached to the inner hole of a feeding hole in a filter plate and has no folds so that the material passes smoothly and is not easily accumulated and the filter cakes are easily formed; the filter cloth bag and the flange elastic sleeve are easy to clean; the flange edge of the flange elastic sleeve is adhered with the filter cloth bag or sewn with the filter cloth bag by adopting an annular fine needle; and a medium needle is used for preventing enlarging, so the filter effect of the material is ensured. The filter cloth bag has the advantages that: 1, the problems that the filter cloth is easy to produce folds so as to produce material accumulation and affect the formation of the filter cakes in the filter chamber in the background technology are solved; and 2, because the sleeve head made of elastic material is adopted in the flange type high polymer elastic sleeve, passages are easy to form, the feeding resistance is reduced and the work efficiency is high.
Description
Technical field
The present invention relates to that a kind of neither can to produce gauffer and biological stockpile long-pending, can not influence the filter chamber filter cake again and be shaped, and the charging resistance is little, a kind of filter press that is used for of high efficiency filters and use the filter cloth bag, belong to filter press with filter cloth bag manufacturing field.
Technical background
At present, the existing middle coupling sleeve that is used for the filter cloth bag of filter press filtration usefulness adopts the filter cloth material to make, the one, owing to make soft, the poor flexibility of middle coupling sleeve material of filter cloth, after forcing to enter the filter plate mouth, not only can't return to reset condition, and it is very serious to cause producing gauffer in charging, filtration are used, the material of being piled up not only makes feeding-passage narrow down, the charging resistance increases, and filter cake is difficult for being shaped, and is cleaning dirty, the coupling sleeve cracky can't use in the middle of the more important thing is; The 2nd, because making to bodkin, makes by the filter cloth cover, it is big that its pinprick in use becomes gradually, influences the material filter effect.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of can be when filtering, a kind of filter press that is used for that the intermediate sleeve of filter cloth can keep being shaped does not all the time have a wrinkle filters and uses the filter cloth bag.
Design: in order to realize above-mentioned purpose of design.On structural design: 1, coupling sleeve is the design of flange form high molecular polymer resilient sleeve between the filter plate two filter cloth sheets, is one of technical characterictic of the present invention.The purpose of doing like this is: it not only possesses coupling sleeve elasticity, and can fold resilient sleeve arbitrarily, the more important thing is since flange form high molecular polymer resilient sleeve when charging, its filter cloth bag and high molecular polymer resilient sleeve linkage path remain shaping, its flange form high molecular polymer resilient sleeve charging aperture sleeve pipe is close to filter board hole, it is non-wrinkled to be shaped, be difficult for piling up material, charging is unobstructed, good filtration effect, so that filter cake is shaped, and clean easily, the anti-intensity that pulls is big during the filter cloth bag filtration simultaneously.2, the flange of filter cloth sheet in the filter cloth bag and flange form high molecular polymer resilient sleeve adopts the design of adhesive bond or fine needle annular no-wrinkle tailoring to connect (two circles or multi-turn are made), is two of technical characterictic of the present invention.The purpose of doing like this is: because flange form high molecular polymer resilient sleeve adopts the high polymer material, possess certain elasticity, easy to leak not when the pinprick that adopts fine needle to make filters, the weak point of having avoided background technology to exist.
Technical scheme: a kind of filter press filtration filter cloth bag that is used for, it comprises the filter cloth bag, described filter cloth bag intermediate sleeve employing macromolecule polymer material is made rubber-like flange resilient sleeve and can be folded arbitrarily, and the charging hole inwall in flange resilient sleeve charging muzzle and the filter plate is close to and is non-wrinkled, make the material that passes through unobstructed, be difficult for piling up, filter cake easily is shaped, filter cloth bag and flange resilient sleeve easy cleaning, the flange of this flange resilient sleeve and filter cloth bag adhesive bond or employing fine needle annular are made connection, pinprick can not become greatly in the use, has guaranteed the good filtration effect of material.
Product of the present invention is compared with background technology, and the one, solved in the background technology filter cloth and overlapped easy gauffer and produce solid accumulation, influence a filter chamber filter cake shaping difficult problem; The 2nd, because flange form high molecular polymer resilient sleeve adopts and to possess elastic material and do pulloverly, passage easily is shaped, and the charging resistance reduces, high efficiency.

The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of filter press filtration filter cloth bag that is used for, it comprises filter cloth bag 2, described filter cloth bag 2 intermediate sleeve employing macromolecule polymer material is made rubber-like flange resilient sleeve 3 and can be folded arbitrarily, and the charging hole inwall in flange resilient sleeve 3 charging muzzles and the filter plate 1 is close to and is non-wrinkled, unobstructed, the difficult accumulation of the material that passes through, filter cake easily are shaped, filter cloth bag 2 and flange resilient sleeve 3 easy cleanings, the flange of this flange resilient sleeve 3 and filter cloth bag 2 adopt adhesive bond or adopt the fine needle annular to make connection, in the use, guaranteed the filter effect of material.The purpose that adopts high molecular polymer to make resilient sleeve 3 is: because high molecular polymer possesses elasticity, can fold arbitrarily, can not produce gauffer, and the anti-intensity that pulls of filter cloth bag is big; The flange adhesive bond of filter cloth bag 2 and flange form high molecular polymer resilient sleeve 3 or adopt annular fine needle to make to connect purpose and be: both solved in the background technology filter cloth cover and adopted bodkin to make and pinprick in use becomes big gradually, influence the defective of material filter effect, guaranteed the filter effect and the filter quality of material again.
Need to prove: though in above-mentioned to the design of the present invention detailed text description of contrasting; but these text descriptions; just the simple text of mentality of designing of the present invention is described; rather than to the restriction of design of the present invention; any combination, increase or modification that does not exceed in the design of the present invention all falls within the scope of protection of the present invention.
