Abstract
The utility model for prior art filter bag filter high flow rate liquid or gas time, cylindrical shell and bottom yielding, cause the deficiency that filter efficiency and quality all reduce, a kind of filter bag is provided, comprise at the bottom of cylindrical shell and bag, the outer setting of the bottom of cylindrical shell has barrel support layer, supporting layer at the bottom of outer setting marsupial at the bottom of bag, barrel support layer is connected by suture with between cylindrical shell, bag the end and bag at the bottom of supporting layer and cylindrical shell, cylindrical shell filtering layer is connected by suture, described cylindrical shell is cylinder, the internal diameter of barrel support layer equals the external diameter of cylindrical shell, the height of barrel support layer is less than or equal to 1/1 to two/4th of barrel lenght, adopt the filter bag of the utility model structure, owing to being provided with supporting layer at the bottom of the bottom of cylindrical shell and bag, can provide strong support to cylindrical shell when filtering high-speed liquid or high-speed gas, prevent barrel distortion, keep water penetration and the filtering accuracy of cylindrical shell, therefore filter efficiency is high, good water permeability, the water content of filter cake is low, filter cake is thick.
Description
Technical field
The utility model relates to a kind of filter bag, particularly filters the filter bag of high flow rate liquid or high flow rate gas.
Background technology
The filter bag of current filter sludge adopts individual layer eedle-punched non-wovens composition top to be tubular, bottom arranges filter bag with the end, adopt this kind of structure, when filter bag is used for high flow rate liquid or high flow rate gas filtration, cylindrical shell is yielding, causes filter effect decline, filtering accuracy reduces, cake moisture is high.
Summary of the invention
The purpose of this utility model be for prior art filter bag filter high flow rate liquid or gas time, cylindrical shell and bottom yielding, the deficiency causing filter efficiency and quality all to reduce, provides the filter bag that a kind of good filtration effect, filter efficiency are high.
Goal of the invention of the present utility model is achieved through the following technical solutions:
A kind of filter bag, comprise at the bottom of cylindrical shell and bag, the outer setting of the bottom of described cylindrical shell has barrel support layer, supporting layer at the bottom of outer setting marsupial at the bottom of bag, barrel support layer is connected by suture with between cylindrical shell, is connected at the bottom of bag with supporting layer at the bottom of bag and cylindrical shell, cylindrical shell filtering layer by suture;
Described cylindrical shell is cylinder;
The internal diameter of described barrel support layer equals the external diameter of cylindrical shell;
The height of described barrel support layer is less than or equal to 1/1 to two/4th of barrel lenght.
Adopt the filter bag of the utility model structure, owing to being provided with supporting layer at the bottom of the bottom of cylindrical shell and bag, can provide strong support to cylindrical shell when filtering high-speed liquid or high-speed gas, prevent barrel distortion, keep water penetration and the filtering accuracy of cylindrical shell, therefore high, the good water permeability of filter efficiency, the water content of filter cake is low, and filter cake is thick.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
As shown in Figure 1, the filter bag of the utility model embodiment by 3 forming at the bottom of cylindrical shell 1 and bag, cylindrical shell with at the bottom of bag between to be sewed up by suture 2 and be connected, constitute the filter course of filter bag at the bottom of cylindrical shell and bag./ to two/4th place accounting for cylindrical shell height at cylinder body bottom is provided with barrel support layer 4, barrel support layer is arranged on the outside of cylindrical shell, the internal diameter of preferred cylindrical shell supporting layer is equal with the external diameter of cylindrical shell, barrel support layer and cylindrical shell are sewed up by suture 2 and are connected, at the bottom of bag 3 outer setting marsupial at the bottom of supporting layer 5, bag end supporting layer is connected by suture with at the bottom of bag, and supporting layer 5 at the bottom of bag is connected with being adjacent at the bottom of bag.
Bottom cylindrical shell lower end and bag, supporting layer is set respectively, when the bottom of filter bag to be subject to when airflow is impacted supporting layer can to the bag of cylinder body bottom and filter bag at the bottom of beneficial support is provided, prevent the distortion that gas shock brings filter course, there is provided secondary filter simultaneously, keep the accuracy that filter bag filters.Only at the bottom of bag and one of 1 to two/4th of cylinder body bottom parts places supporting layer is set, compared with arranging supporting layer with direction at the bottom of the total length of cylindrical shell, its advantage is: the water penetration that 1, can keep filter course; 2, in the cumulative process of filter mud, first be accumulated in bottom filter mud and provide lasting pressure at the bottom of cylinder body bottom and bag, at the bottom of easily making bag and the filter course distortion of cylinder body bottom, reduce the precision of permeability rate and filtration, and owing to just carrying out current limliting and filtration to filtrate in the top of cylindrical shell, without the need to bearing the pressure of filter mud, therefore, adopt and supporting layer is set at the bottom of cylinder body bottom and bag, effectively can improve the accuracy of filtration, keep the quality of efficiency and the filter cake filtered, cake moisture can not be made too high.
Especially at the bottom of the bag of filter bag, arrange supporting layer, the impulsive force that can absorb high velocity air or high-speed liquid stream more effectively reduces the distortion of cylindrical shell, therefore improves filter effect and the rate of filtration.
Preferred cylindrical shell is cylinder.The material of certain supporting layer is preferably identical with the material at the bottom of bag with cylindrical shell, also can be different.In the utility model embodiment, filter bag is acupuncture filter-cloth filtering bag.
