Problems solved by technology

[0019] However, the base fabric layer 20 of the filter cloth F described in this patent document 3 is formed by winding the woven fabric in the shape of a belt into a helical shape and then sewing it into a cylindrical shape. Therefore, when the filter cloth F is installed In the filter cloth structure used on the holder, since there is no measure to strictly limit the length of the filter cloth F in the cylindrical axis direction X, the filter cloth F is pulled in the cylindrical axis direction X due to its own weight during use. so that it hangs down from the lower end of the cage
[0020] In addition, if no special treatment is performed on the drooping part, the tension of the filter cloth F will disappear, which will reduce the dust-off efficiency of the captured dust, and the filtering function of the filter cloth F will also be reduced accordingly, and the stress will be concentrated. The sagging part is prone to damage, which hinders the energy saving of the filter cloth F and the improvement of the life of the filter cloth F.

Embodiment Construction

[0052] Hereinafter, embodiment of the filter cloth structure of this invention is demonstrated based on drawing.

[0053] figure 1 and figure 2 A dust collector to which the filter cloth structure of the present invention is applied is shown in .

[0054] In this dust collector, the inside of the housing 2 is divided into a dusty air introduction chamber 4 (also referred to as a polluted side) and a clean air chamber 5 (also referred to as a clean side) by a partition wall 3 .

[0055] The dust-laden air introduction chamber 4 has a cone-shaped falling dust receiving portion 4b at the lower portion, and a falling dust discharge port 4c is provided at the bottom of the tapered falling dust receiving portion 4b.

[0056] In addition, a dust-laden air introduction port 4 a for introducing dust-laden air A into the dust-laden air introduction chamber 4 is provided on a side portion of the dust-laden air introduction chamber 4 .

[0057] A clean air suction pipe 6 including a s...

Abstract

The invention provides a filter cloth structural body, and the structural body can improve the dust cleaning efficiency during the regeneration of filter cloth, can save energy because of the reduction of the loss of mean pressure of the filter cloth, and can prolong the service life of the filter cloth. The structural body is formed in a manner that the filter cloth (F) is installed on a holder (C), wherein the length (Lf) of the filter cloth is shorter than the length (Lc) of a filter cloth installation part (Ca) of the holder (C). The filter cloth (F) is installed at the filter cloth installation part (Ca) of the holder (C) in an extending manner.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2015-081724 filed on April 13, 2015. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The present invention relates to a filter cloth structure used for dust collectors and the like. Background technique [0003] Conventionally, as a filter cloth used in dust collectors, etc., a filter cloth made of a base fabric layer composed of a woven fabric and a nonwoven fabric bonded to at least the filter surface side of the base fabric layer has been widely used. The filter cloth roll made of filter layer is formed into a cylindrical shape, and the dusty air is filtered through the filter cloth from the filter surface side of the filter cloth to the back side of the filter cloth, and the countercurrent airflow is passed from the back side of the filter cloth Pass the filter cloth sideways to the filter surface to dust off the collected dust...
