FIG. 7 is a view showing a method of manufacturing a large-scale incinerable filter structure according to a second embodiment of the present invention, and FIG. 8 is a view showing a gap holding jig according to a second embodiment of the present invention.

The method for manufacturing the large-scale incinerable filter structure 200 according to the second embodiment of the present invention is a nonwoven fabric manufactured by a neddle punching method at a high temperature (180 to 260 ° C) or a room temperature (120 ° C or less) Is impregnated with a heat-resistant resin, and is then bended and cured after drying at a low temperature.

First, a glass fiber cloth of 1000 Deniar thickness and 10 × 10 mesh was prepared and a PTFE (Polytetrafluoroethylene) aqueous solution (about 60 wt% solids) was added in a weight ratio of 10 to 50% in order to reduce damage to the fabric during needle punching. , The glass fiber fabric is impregnated with the solution, dried, and heat-treated at a temperature of 300 to 350 ° C. This is because PTFE is coated on a glass fiber fabric and PTFE is lubricated during needle punching, so that fiber damage can be minimized.

Here, a 1000 Deniar multi filament made of fine fibers having a diameter of about 10 ㎛ in diameter is cut into a length of 30 - 60 mm and carded to a web of a certain thickness and width by a molding machine After shaping, the glass fiber cloth coated with PTFF is needle punched at a weight of 200 to 300 g / m < 2 > to produce a glass fiber nonwoven fabric laminated with a glass fiber fabric.

Next, the present invention is to impregnate the nonwoven fabric and the glass fiber nonwoven fabric produced by the needle punching method at room temperature or high temperature into the heat resistant resin aqueous solution.

The impregnation process increases the heat resistance of the nonwoven fabric and improves the lubricity of the filter fiber to reduce abrasion caused by friction between the fibers, and also to improve bending performance and draining performance.

Preferably, the heat resistant resin aqueous solution is a mixture of a phenol resin aqueous solution and a PTFE aqueous solution, more preferably 10 to 40% by weight of a phenol resin aqueous solution and 60 to 90% by weight of an aqueous PTFE solution, Bending performance and exhausting performance. As a concrete example, it is of course possible to use a 60% aqueous phenol resin solution or a 58% aqueous PTFE solution which is commercially available.

The content of the heat resistant resin aqueous solution may be appropriately adjusted by those skilled in the art, and it is preferable to use 10 to 80 parts by weight, more preferably 20 to 50 parts by weight, based on 100 parts by weight of the impregnated nonwoven fabric. Within the above range, the durability, heat resistance, etc. of the cartridge filter manufactured in the subsequent step and manufactured are better.

Next, the present invention is impregnated with the heat resistant resin aqueous solution, and then the nonwoven fabric is subjected to a low temperature drying step. This process removes the liquid component from the heat resistant resin aqueous solution in the nonwoven fabric and has a stiffness enough for bending.

If the nonwoven fabric is too stiff, the fibers will be damaged during the bending process, resulting in a lower tensile strength, resulting in a shorter life of the cartridge filter bag. The temperature for low-temperature drying is preferably 80 占 폚 or lower, and it is preferable to adjust the temperature to 50 to 80 占 폚 in consideration of productivity.

The low temperature dried nonwoven fabric is bent using a bending machine. Here, before bending the nonwoven fabric, it can be preheated to 50 to 100 DEG C, which helps to ensure that the nonwoven fabric has a degree of stiffness suitable for bending.

More preferably, the bending and curing of the present invention is preferably performed using a knife-type bending machine equipped with a preheater and a postheater. In the bending machine, the preheater performs a preheating process before bending, and the postheater performs a bending curing process.

The folded nonwoven fabric is made into a cartridge filter bag (210) for dust collection at room temperature and high temperature through a curing step.

6, a coil spring 240 is mounted on upper and lower portions of the cartridge filter bag 210, and the crests 210a and 210b of the cartridge filter bag 210, And the gap holding jig 250 is engaged with the valley portion 210b.
The coil spring 240 is engaged with the crest portion 210a and the valley portion 210b of the cartridge filter bag 210 so as to surround the outer periphery of the cartridge filter bag 210.
The gap holding jig 250 is formed of a jig body 252 having a predetermined thickness and length and is coupled to the jig body 252 at regular intervals, 254 are formed to be engaged with the crests 210a and the valleys 210b of the cartridge filter bag 210, respectively.
The cartridge filter bag 210 is formed by joining one or more coil springs 240 and the gap retaining jig 250 to the crests 210a and the valleys 210b of the cartridge filter bag 210, The shape retaining band 217 is wound around the outer periphery of the cartridge filter bag 210 and attached to each crest part 210a of the cartridge filter bag 210. [
After the shape retaining bands 217 are coupled to the top and bottom of the cartridge filter bag 210 in six places, a plurality of staples 218 are stamped on each shape retaining band 217 to further strengthen the retaining force.
The coil spring 240 and the gap retaining jig 250 are formed in the shape of a rectangular parallelepiped shape when the shape retaining band 217 is wound around the outer periphery of the cartridge filter bag 210, 210b are kept constant.
The gap between the crests 210a and the valleys 210b of the cartridge filter bag 210 must be maintained constantly because the crests 210a of the cartridge filter bag 210 are removed before the shape- If the gap between the filters is widened or adhered to, the final filter product can not function properly.
The present invention maintains the interval between the peak 210a and the valley 210b of the cartridge filter bag 210 constant before winding the shape retaining band 217 around the outer periphery of the cartridge filter bag 210 Melt adhesive applied to the shape retaining band 217, the stapler 218, the gap retaining jig 250, the coil spring 240, the silicon retaining member 219, and the shape retaining band 217 do.
