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.

Embodiment 1

[0105] The weight of polyaramide (Polyaramide) is made into 150g / m by spunlace method 2 , a thickness of 1.0㎜, a tensile strength of 50㎏ / 5㎝ (cut strip method), an elongation of 25%, and a deviation of 20% in the left and right tensile strength of the non-woven fabric, relative to the impregnated 100 weight % of the non-woven fabric was impregnated with 40% by weight of a heat-resistant resin aqueous solution consisting of a 1:2% by weight mixture of 60% phenolic resin aqueous solution and 58% PTFE aqueous solution, and then dried at 60° C. for 1 hour , and preheated in a preheater at 80°C for 20 minutes using a knife folding machine, and then folded and cured in a post-heater at 330°C for 20 minutes to manufacture a pleated filter for high-temperature dust removal.

Embodiment 2

[0107] A pleated filter for high-temperature dust removal was produced in the same manner as in Example 1 except that a nonwoven fabric produced by hydroentanglement using polyimide was used.

Embodiment 3

[0109] A pleated filter for high-temperature dust removal was produced by the same method as in Example 1 except that a nonwoven fabric produced by hydroentanglement using PPS was used.

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...
