Description

Housingless type filter module and method for fabricating the same

The present invention relates to a housingless filter module assembly and a method for manufacturing the same.

In general, a water purifier is a device for supplying drinkable purified water by removing harmful substances from incoming raw water such as tap water, and a filter module assembly is used as a core component for removing harmful substances.

As for the filtration method of the filter module assembly, the direction of treatment technology is changing from the conventional sand filtration method to the membrane filtration method using a separation membrane as the water treatment technology for purified water and wastewater is developed.

Separation membrane technology is a high-level separation filtration water treatment technology to almost completely separate and remove the treatment target material present in the treated water according to the membrane pore size, pore distribution, and membrane surface charge.

Separation membrane, a core component, is divided according to the size of pores and is classified into microfiltration membrane (MF membrane), ultrafiltration membrane (UF membrane), nano separation membrane (NF membrane), and reverse osmosis membrane (RO membrane). The scope of its application is expanding, including the production of industrial water, sewage/wastewater treatment and reuse, and the clean production process related to the development of a non-discharge system.

In line with the trend of serious water pollution, this separation membrane technology has been established as one of the core technologies that are attracting attention in recent years, and in fact, tap water supplied by ordinary people after being purified is reprocessed through a water purifier and used for food. In this regard, technological development is increasingly required.

On the other hand, the water purifier system is composed of a separation membrane module, pre- and post-treatment filters, pumps, pipes, tanks and other auxiliary devices.

Plate type, hollow fiber type, tubular type, spiral wound type, etc. are commercialized as types of such filter module assemblies, and spiral wound type separation membrane module filter module assembly that has a high separation membrane insertion density per unit area and can remove ions in water. Research is mainly in progress.

As shown in FIG. 6, the generally known filter module assembly 1 includes a hollow cylindrical housing 10 and a perforated tube 30 having a plurality of inlet holes 35 through it in the longitudinal direction in the center of the body. It includes a filter body 20 which is a separation membrane module provided, and the housing 10 accommodates and assembles the filter body 20 so that the outer end of the brine seal 13 is in contact with the inner surface.

A cap 40 having a raw water inlet 41 through which raw water is introduced is assembled on one opened side of the housing 10, and a purified water outlet 15 through which purified water, which is produced water, is discharged on the other sealed side of the housing, and a concentrated water outlet 16 through which concentrated water is discharged.

Accordingly, in the filtration process of purifying raw water using the filter module assembly 1, when raw water pressurized through the raw water inlet 41 flows in one direction, the filter body 20 housed inside the housing 10 The foreign substances contained in the raw water are filtered while passing through, and purified water, which is water filtered while passing through the separation membrane module, is collected through the perforated pipe 30 and discharged to the outside through the purified water outlet 15, and the concentrated water remaining after purified is concentrated Water is discharged to the outside through the water outlet 16 .

However, in this conventional filter module assembly (1), the separation membrane of the filter body (20) accommodated in the housing (10) frequently occurs due to internal differential pressure that is unavoidably generated in the space formed between the housing and the filter body (10). As it was damaged, the filtration and water purification efficiency was lowered, which shortened the replacement period of the filter module assembly and acted as a major cause of increasing the maintenance cost.

In addition, in the process of assembling the cylindrical filter body to embed the cylindrical filter body inside the housing, assembly defects due to dimensional errors occur, and the manufacturing cost is increased in the process only when all defective components are disposed of, while the miniaturization of the water purifier In keeping with the trend, the volume of the housing accommodating the separation membrane module was reduced to reduce the volume of the filter module assembly, thereby limiting the design of miniaturization.

Accordingly, the present invention is to solve the above-described problems, and its purpose is to fundamentally prevent damage to the separator module due to the internal differential pressure generated when the housing is applied, and to prevent the housing and separator module from being dimensionally defective. An object of the present invention is to provide a housingless filter module assembly and manufacturing method that can fundamentally prevent assembly defects of the liver.

An inner circumferential surface of the first cap is coupled to an outer surface of one end of the filter body via a first sealing material so as to increase a bonding force with one end of the filter body, and an inner circumferential surface of the second cap is coupled to the other end of the filter body It is coupled to the outer surface of the other end of the filter body through a second sealing material to increase the bonding force of the filter body,
One end of the outer edge of the filter body is engaged with a first locking jaw formed on the inner surface of the first cap, so that the raw water is filled between the inner surface of the first cap and one end of the filter body. A space is formed, and the outer edge of the other end of the filter body is hooked on a second locking jaw formed on the inner surface of the second cap, so that the concentration is between the inner surface of the second cap and the other end of the filter body. A method of manufacturing a housingless filter module assembly, which forms a second space filled with water. delete delete delete delete 11. The method of claim 10,
The step of forming the exterior part,
The start end of the winding material is wound and fixed to the first extension pipe extending from the first cap to the second cap side, and the middle length of the winding material is spirally wound to cover the outer surface of the filter body, and then the winding material A method for manufacturing a housingless filter module assembly, wherein the end end of the filter module assembly is wound and fixed to a second extension pipe extending from the second cap to the first cap side to form the exterior part. 11. The method of claim 10,
The step of forming the exterior part,
The winding material spirally wound on the outer surface of the filter body is wound in the same direction as the winding direction in which the filter sheet of the filter body is wound on the perforated tube while winding so that both edges of the adjacent winding materials overlap each other. Housingless A method for manufacturing a type filter module assembly. 11. The method of claim 10,
After the step of forming the exterior part, further comprising the step of integrating the exterior part with the first and second caps and the filter body,
In the step of integrating the exterior part, the exterior part is cured by irradiating heat or ultraviolet rays to a winding material made of an ultraviolet curable resin film to integrate the exterior part with the first and second caps and the filter body, a housingless type filter module assembly manufacturing method . 11. The method of claim 10,
After the step of forming the exterior part, further comprising the step of integrating the exterior part with the first and second caps and the filter body,
In the step of integrating the exterior part, a winding material made of a resin film having an adhesive layer coated with an adhesive on one surface is adhered while the starting end is wound to the first cap, and the middle length is spirally wound on the outer surface of the filter body. A method of manufacturing a housingless filter module assembly, wherein the outer portion is integrated with the first and second caps and the filter body while being adhered and the end end is wound around the second cap to form an outer portion.
