A fold type filter and a method for manufacturing the same

Abstract

The invention provides a method for manufacturing a fold type filter. The method comprises the steps of soaking non-woven cloth or glass fiber non-woven cloth manufactured at high temperature or normal temperature in a heat-resisting resin water solution for dipping processing; taking the non-woven cloth or glass fiber non-woven cloth out and drying the non-woven cloth or glass fiber non-woven cloth at low temperature; folding the non-woven cloth or glass fiber non-woven cloth and then solidifying the same; winding a shape-maintaining band around and combining the shape-maintaining band to the periphery of the solidified folded non-woven cloth, namely the fold type filter bag; driving in U-shaped nails from the outside to fix the shape-maintaining band, wherein the shape-maintaining band is an annular band in the length direction and the inner side surface thereof is coated with adhesive.

Description

technical field [0001] The present invention relates to a pleated filter, in particular to a pleated filter, through various means of maintaining the distance between the pleated peaks and pleated valleys of the pleated filter bag, even if the length of the pleated filter bag changes A pleated filter capable of maintaining a certain distance between pleated peaks and pleated valleys of a pleated filter bag to prevent deformation of the pleated filter bag and a manufacturing method thereof. Background technique [0002] The dust removal device is an air purification device that filters the gas containing dust, etc., and then sends it into the room or discharges it to the outside. [0003] The conventional structure of the dust removal device is composed of an air intake chamber, an exhaust chamber, an air inlet, an exhaust part, a filter, a compressed air supply pipe, and a nozzle. The air intake chamber and the exhaust chamber in the housing are separated by a partition wal...

AI Technical Summary

Problems solved by technology

[0013] Such a large pleated filter is difficult to maintain the spacing of multiple pleated peaks during the manufacturing process, and the spacing between the pleated peaks of the pleated filter bag 110 will be locally widened and lose the unique advantages of the pleated filter (for example, handling air volume Large size, energy saving, miniaturization of dust removal device, etc.), and the adjacent pleats will stick together, resulting in the failure of the filter to function normally.
