Description

Multi Structure filter cartridge

The present invention relates to a filter cartridge for filtering foreign substances in fluids and liquids. More specifically, the filter cartridge 400 for filtering foreign substances in a liquid inflow process may have different diameters of filter cartridges having different absorption holes. It is a filter to be used as one multi-structure filter cartridge 400. More specifically, a multi-structure filter cartridge 400 in which an aggregate having different filtration effects penetrates a central portion in one cylindrical shape and an aggregate having different filtration effectiveness enters into the hole and is cylindrically attached in the form of a normal body. will be.

The present invention relates to a filtration filter cartridge used in various fields such as electronic components, food, medicine, and pure water, and more particularly, to a multi-structure filter cartridge 400 for filtering foreign substances in the process of introducing a fluid or a liquid. .

Currently, various filters have been developed and produced to purify fluids or liquids. A typical filter cartridge is a device that is composed of replaceable cylinders so that fluids or liquids are sucked in to filter out impurities such as dust and powder so that a high-purity emulsion or liquid can be used. Since the conventional filter is filtered by only one filter unit, as shown in FIG. 1, precise filtration cannot be performed, and the filter has to be used separately according to impurity filter particles, and maintenance costs are also increased. There is this.

Conventional filter cartridges consist of a single filter portion, which makes it difficult to adjust the size or shape of the gap, so there is a drawback that the size and amount of particles that can be sucked are limited. In addition, as shown in Fig. 1, a filter having a structure in which a wide nonwoven fabric is rolled around a perforated ordinary body as it is, and a so-called nonwoven laminated filter cartridge is limited in size of the filtration particles, and differs depending on the filtration particles. There is a disadvantage to use, which increases the manufacturing cost of use.

Another drawback of the above-described conventional filtration filters is that the support is cylindrical and thin, so that the support for pressure is weak and thus the filter body is easily broken when subjected to an external pressure exceeding the support. In order to eliminate these drawbacks, the support should be formed thickly. If the support is thickened, the length and thickness of the filter medium should be made thin, resulting in a decrease in capacity.

In view of these various problems, a multi-structure filter cartridge 400 which integrates several filter cartridges having a specific diameter and absorption holes into one cylindrical filter cartridge increases the filtration capacity, the filtration efficiency, and reduces the cost. It can be seen that it is necessary.

In order to solve the above problems, the filter cartridge, in which the absorbing holes are used differently according to the particle size to be filtered, is not affected by the size of the filter particles, and is liquid permeable to a common body having a hole capable of precisely filtering foreign substances. To provide a tubular multi-structure filter cartridge 400 excellent in the stability of filtration life and filtration precision.

In addition, to provide a filter cartridge having a multi-structured filter of a variety of materials having the above structure that can filter the foreign matter precisely without being affected by the filter cartridge used differently for each filter material.

In order to achieve the problem to be solved, the unit of the particle size is larger so that the foreign matter is filtered out, that is, the unit of the filter particle size penetrating through the central portion and the outer filter portion 200 or 300 having a larger absorption hole is smaller. In addition, a cylindrical inner filter part 210 or 310 & 320 having a smaller absorption hole and smaller diameter than the outer filter part 200 or 300 is fastened in the outer filter part 200 or 300 to become a single filter part to prevent foreign substances in a fluid or liquid. It includes a state in which the through-hole is re-filtered and the central portion through which the fluid filtered by the inner filter unit 210 or 310 & 320 can move.

The material of the filter may be polypropylene, poly vinylidene fluoride, polyethylene, polyolefin, etc. In some cases, the external filter unit 200 or 300 may be used. It includes a state formed by varying the material of the internal filter unit (210 or 310 & 320).

As described above, according to the multi-structure filter cartridge 400 according to the present invention provides the following effects.

First, the foreign matter of the fluid and the liquid is first filtered in the outer filter unit 200 or 300 and secondly filtered in the inner filter unit 210 or 310 & 320 can be precise and sophisticated filtration can increase the filtration efficiency.

Second, because the filter can be used to obtain a high filtration efficiency because of the double filter can be used in a narrow place by using the filter housing for one multi-structure filter cartridge 400, the space utilization is high, and the housing use cost can be reduced.

Third, the internal filter unit 210 or 310 & 320 is formed to have a smaller absorption hole than the external filter unit 200 or 300 to alleviate the impact that the external filter unit 200 or 300 receives from the fluid or liquid, Can extend its life.

Fourth, since the material of the outer filter unit 200 or 300 and the inner filter unit 210 or 310 & 320 can be used differently, it is possible to reduce the cost by using one multi-structure filter cartridge 400 without using filter cartridges of different materials separately. Reduce and increase the filtration efficiency.

Fifth, when using the end cap (410) and the flange (flange) 420 can be combined with a variety of external fastening portion can increase the practicality.
