Problems solved by technology

[0003]The traditional method of making double-layer corrugated filter cloth is to connect the crests of one layer of corrugated filter cloth with the troughs of another layer of corrugated filter cloth, Brush the connecting medium glue on the place, and when the glue is solidified, the two layers of corrugated filter cloth are connected together to form a double layer of corrugated filter cloth. Layers of corrugated filter cloth connected to each other are prone to separation, and can no longer form a mutually supporting structure, which makes the strength of the filter element invalid and can no longer be used, which affects the use effect of the industrial dust collector

Embodiment Construction

[0044] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] Such as figure 1 As shown, it is a double-layer corrugated filter cloth according to the present invention, including two layers of corrugated filter cloth 10 arranged oppositely. The cloth 10 is arranged symmetrically, so that the troughs of one layer of corrugated filter cloth 10 are in contact with the peaks of another layer of corrugated filter cloth 10, and then ultrasonic welding is performed on the conflicting positions. The width L of the welded seam 21 after welding is 1~ 1.5 mm, a channel 22 is formed between two adjacent welds 21 .

[0046] Using ultrasonic welding and setting the weld seam to a width L of 1 to 1.5mm can improve the strength of the weld seam 21 of the double-layer corrugated filter cloth and the overall structural strength of the double-layer corrugated filter cloth. The two-layer corrugated filter cloth 10 ...

Abstract

The invention discloses double-layer corrugated filter cloth. The double-layer corrugated filter cloth comprises two layers of corrugated filter cloth arranged oppositely. The folding angle beta of the two layers of corrugated filter cloth is not larger than 30 degrees, the two layers of corrugated filter cloth are symmetrically arranged, wave troughs of one layer of corrugated filter cloth abut against wave crests of the other layer of corrugated filter cloth one to one, then the abutting positions are subjected to ultrasonic welding, the width L of weld joints obtained after welding is completed ranges from 1 mm to 1.5 mm, and a channel is formed between every two adjacent weld joints. The weld joints of the double-layer corrugated filter cloth welded ultrasonically are firm and not likely to be separated, the service life of the double-layer corrugated filter cloth is greatly prolonged, no connecting medium exists, no medium disengaging phenomenon is generated, and it is completely eradicated that new contaminates are formed for an industrial dust remover by the double-layer corrugated filter cloth.

Description

technical field [0001] The invention relates to a double-layer corrugated filter cloth and its welding positioning device, welding device and welding method. Background technique [0002] Double-layer corrugated filter cloth is a kind of filter element material, which is widely used in the manufacture of flat frame filter elements. The double-layer corrugated filter cloth is formed by connecting the peaks to the troughs of two layers of corrugated filter cloth. Directly arranged channels, the double-layer corrugated filter cloth uses its corrugated shape and closed channels to increase the speed of airflow, avoid mutual interference of airflow, and improve the use effect of the filter element. [0003] The traditional method of making double-layer corrugated filter cloth is to connect the peaks of one layer of corrugated filter cloth with the troughs of another layer of corrugated filter cloth, and then brush the connecting medium glue on the seams, and when the glue solidif...
