Abstract
A filter structure capable of being incinerated and a manufacturing method thereof are characterized in that a top cap, a bottom cap, and a supporting frame inserted in a net structure are formed of a plastic material, which is coupled to a cartridge filter bag, do.
Description
In particular, the present invention relates to a filter structure, and more particularly, to a filter structure comprising a top cap coupled to a cartridge filter bag, a bottom cap, and a support frame inserted into the net structure in a plastic material, And to a process for producing the same.
The dust collecting apparatus is a kind of air purifying apparatus that filters a gas containing dust or the like and then flows it back into the room or discharges it to the outside.
The general structure of the dust collecting device is composed of an intake chamber, an exhaust chamber, an intake port, an exhaust portion, a filter, a compressed air supply pipe, and a spray nozzle. The intake chamber and the exhaust chamber in the housing are separated by a partition.
The gas introduced into the intake chamber through the intake port is moved to the exhaust chamber after dust or the like is caught by the filter. The gas moved to the exhaust chamber flows into the room through the exhaust unit or is discharged to the outside.
The dust collecting apparatus is provided with a plurality of filters. The dust collecting filter needs to have heat resistance so as to withstand warm gas and has a surface area as wide as possible in order to increase the filtering efficiency. A filter with a large surface area is a cartridge filter.
The conventional cartridge filter includes a cartridge filter bag folded into a cylindrical shape and folded so as to form a plurality of corrugations, a top cap and a bottom cap respectively coupled to upper and lower portions of the cartridge filter bag, Respectively.
The upper cap, lower cap, and support frame are typically made of a metal such as aluminum.

The method for manufacturing the large-scale
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.
