The special filtering bag for the polyacrylamide solution has the advantages that the bottom is a flat bag bottom, and the bag bottom and the bag body are of an integrated structure, so that the structure is firmer, when impurities are deposited in the bag bottom of the filtering bag, the bag bottom cannot be broken due to excessive deposits, the service time of the filtering bag is prolonged, the filtering bag does not need to be frequently replaced, and the working efficiency is improved; the sewing positions of the filter bag are all sewn by 3 threads, so that the sewing positions are firmer and are not easy to break; and through infrared ray singeing treatment, the filtering surface has no fibers easy to fall off, and the filtered polyacrylamide solution can be prevented from being secondarily polluted.
Description
Technical Field
The utility model belongs to be used for liquid filter element, especially relate to a special filter bag of crossing of polyacrylamide solution.
Background
The filter bag is a filter element which can make the liquid in suspension or gas in gas flow containing solid particles permeate through under the action of external force, and can retain the solid particles so as to separate the solid particles from the liquid or gas. The polyacrylamide solution needs to be used after being filtered, the existing polyacrylamide solution filter bag is cylindrical, the bag body and the circular bag bottom are sewn together through a seam, when the sediment in the bag bottom is too much, the seam between the bag body and the bag bottom is very easy to break, or the bag bottom is broken, the polyacrylamide solution filter bag needs to be frequently replaced, the working cost is increased, and the working efficiency is reduced.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a special filter bag for polyacrylamide solution.
The utility model discloses a special filter bag of crossing of polyacrylamide solution, including bag body and circular sack, the bag body is the cylindric bag body, and its both sides wall overlaps each other and sews up and form the seam, and bag body top is equipped with circular sack, the interior parcel has steel ring, bag body bottom to flat bag end.
As a further improvement of the utility model, the top end of the bag body is bent inwards and sewn into a round bag mouth, and the bottom of the bag body is kneaded and is sewn into a flat bag bottom by bending towards the outer wall of one side.
As a further improvement of the utility model, the stitches of the circular bag mouth, the flat bag bottom and the seam are sewn by a three-needle machine, and every 3cm of the bright and dark lines has 7-10 needles.
As a further improvement of the utility model, the outer surface of the bag body is a filtering surface.
As a further improvement of the utility model, the bag body is made of non-woven fabrics.
As a further improvement of the utility model, the bag body is made of nylon net or nylon net.
The special filtering bag for the polyacrylamide solution has the advantages that the bottom is a flat bag bottom, and the bag bottom and the bag body are of an integrated structure, so that the structure is firmer, when impurities are deposited in the bag bottom of the filtering bag, the bag bottom cannot be broken due to excessive deposits, the service time of the filtering bag is prolonged, the filtering bag does not need to be frequently replaced, and the working efficiency is improved; the sewing positions of the filter bag are all sewn by 3 threads, so that the sewing positions are firmer and are not easy to break; and through infrared ray singeing treatment, the filtering surface has no fibers easy to fall off, and the filtered polyacrylamide solution can be prevented from being secondarily polluted.

Detailed Description
Example 1
The utility model discloses a special filter bag of crossing of polyacrylamide solution, bag body 1 is made by nylon wire or polyamide fibre net, is applicable to the coarse filtration. The bag body 1 be the cylindric bag body, its both sides wall is mutual overlap, sew up and form seam 4, bag body 1 surface is for straining out the face, and the inside bending seam of bag body 1 top is made circular sack 2, the circular sack 2 inner parcel has the steel ring, kneads in bag body 1 bottom, and to one side outer wall bending seam flat bag end 3. More sediments can be piled up in the flat bag bottom 3 without breaking, and the flat bag bottom 3 and the bag body 1 structure as an integral type can make this filter bag more firm, increase the live time of this filter bag, need not often to change the filter bag and improved work efficiency.
When the filter bag is sewn, the stitches of the circular bag opening 2, the flat bag bottom 3 and the seam 4 are sewn by a three-needle machine, and each 3cm of the bright and dark stitches has 7-10 needles, so that the toughness of the stitches can be enhanced, and the filter bag is firmer.
Example 2
The utility model discloses a special filter bag of crossing of polyacrylamide solution, bag body 1 is made by the non-woven fabrics, is applicable to the smart filtration. The bag body 1 be the cylindric bag body, its both sides wall is mutual overlap, sew up and form seam 4, bag body 1 surface is for straining out the face, and the inside bending seam of bag body 1 top is made circular sack 2, the circular sack 2 inner parcel has the steel ring, kneads in bag body 1 bottom, and to one side outer wall bending seam flat bag end 3. More sediments can be piled up in the flat bag bottom 3 without breaking, and the flat bag bottom 3 and the bag body 1 structure as an integral type can make this filter bag more firm, increase the live time of this filter bag, need not often to change the filter bag and improved work efficiency.
When the filter bag is sewn, the stitches of the circular bag opening 2, the flat bag bottom 3 and the seam 4 are sewn by a three-needle machine, and each 3cm of the bright and dark stitches has 7-10 needles, so that the toughness of the stitches can be enhanced, and the filter bag is firmer. The outer surface of the bag body 1 is a filtering surface, and the filtering surface is free of fibers which easily fall off after infrared singeing treatment, so that the filtered polyacrylamide solution can be prevented from being secondarily polluted.
