TECHNICAL FIELD [0001] The present invention relates to a device for manufacturing a functional deep-

The present invention relates to an apparatus and a method for manufacturing a functional deep-drawn filter, and more particularly, to a method for removing a specific metal ion component contained in a water in a water depth filter, which removes fine suspended substances contained in industrial water and domestic water The present invention relates to an apparatus and a method for manufacturing a functional deep-layer filter that increases the efficiency of use and improves the quality of a product by allowing continuous production.

In general, water such as living water or industrial water contains foreign particles or impurities composed of various particles. Therefore, a micro filter is mainly used to purify the water and obtain clean water.

The microfilter is applied to general water, chemical treatment water, foods, dyes, etc., and it is used for deep filter, which filters particles of 0.5 to 100 μm, wrinkle filter (for food and beverage, cosmetics, Pleated Filter, Membrane Filter which is applied to food and beverage and cosmetics and removes particles and microorganisms less than 1.0 ㎛.

In addition, since the deep layer filter has disordered grid structure, the airtightness is assured, the price is low, the range of application is wide, the foreign matter containing a wide particle distribution can be effectively removed, and also the filtration of viscous fluid is effective Widely used.

Such a deep filter is made by arranging the synthetic resin fibers as a raw material in parallel or in an indefinite direction and bonding them with a synthetic resin adhesive to make the felt nonwoven fabric more than a cylindrical support. '), The synthetic resin fibers are directly laminated on the rotating support body 10' to form a filter structure. The material of the synthetic resin fibers to be radiated at this time is different in density, radial position, and radiation pattern The shape of the filter can be changed.

 On the other hand, during operation of the wastewater treatment plant, only one or two specific components among the various metal components in the water may exceed the treatment standard due to the change of the production process, the change of the product, and various chemicals to be added to the wastewater treatment process.

In this case, since facilities for removing the metal components should be additionally installed in existing facilities, it is complicated and requires a lot of time, cost, and location. In order to leave the environment, There was a problem such as violation.

For example, conventionally, in order to remove metal ions in water, a plurality of filters for filtering suspended substances (foreign substances) are connected in series, and a column capable of inducing a reaction separately is connected, A method is known in which a resin cartridge is charged and water is passed therethrough to induce a reversible reaction to remove ion components.

In this case, the ion exchange resin is a bead-shaped polymer having a water content of about 30 to 50%. If the ion exchange resin is to be formed into a filter form, a cartridge is formed and a water inlet and an outlet It was necessary to employ a method of screening such as a mesh to prevent leakage of the exchange resin, or to insert an ion exchange resin between two nonwoven fabrics.

However, when the ion exchange resin is formed of a separate cartridge as in the conventional method, the system may be complicated because it must be connected to the water filter in multiple stages. When the ion exchange resin is disposed between the nonwoven fabrics A second process is required to apply heat or an adhesive. Therefore, there is a problem that the process is troublesome and the process cost is extra, and there is a disadvantage that it can not be applied to the deep filter due to the difference in processing method.

This will be described in more detail as follows.

The support body 10 is a cylindrical frame having a predetermined length, and the core 11 is disposed at the center of the support body 10 and is rotated and interlocked (right and left reciprocating) by the motor M. The support 10 may be any known one.

The radiator 20 forms a filter by laminating a synthetic resin fiber (filter raw material), which is a raw material of a nonwoven filter, on the outer circumferential surface of the support 10 so as to have a cylindrical shape, and at least one or more fixed .

In other words, the radiator 20 may be installed in one or more layers depending on whether a filter having a single layer or a layered filter is to be manufactured. In the present invention, preferably, the radiator 20 is provided with two or more layers.

The radiator 20 is provided with a spinning nozzle 21 at its tip end, and a known melt extruder 25 is connected to receive molten synthetic resin fibers.

A separate water jetting device 22 is provided around the radiator 20 so as to cool the molten resin to a certain extent by finely spraying water toward the molten resin laminated on the outer circumferential surface of the support body 10 It is possible.

It is preferable that it is provided at a position adjacent to the support body and is provided between the radiator 20 and the radiator.

The injector 30 is vertically long in the shape of a pipe so as to control the injection quantity of the functional material moving inside.

The sprayer 30 is provided with a spray nozzle 31 at its distal end and a spray pump 32 at its distal end so as to approach the support. The spray pump dispenses the functional substance and moisture to the spray nozzle while reciprocating do.

As shown in the drawing, each component according to the present invention can be disposed inside the box-shaped housing 100, and this configuration can be applied in various forms by arranging one or several pieces in a row in the entire process of manufacturing the filter .

Next, a method for manufacturing a functional deep layer filter according to the present invention will be described.

[1] Supply of functional materials

First, the functional material (I) is prepared.

The functional material is stored in the supply part 101 provided at the lower part of the box-shaped housing 100 or the separately provided supply part together with water. At this time, the functional material uses an ion exchange resin, A bead-shaped resin having a size of 1.0 mu m-1.0 mm is preferably used so as to be homogeneously distributed on the outer circumferential surface of the support during the lamination.

The ion exchange resin may be selected from a cation exchange resin and an anion exchange resin, as well as an amphoteric resin, an electron exchange resin and a chelate resin.

[2] Nonwoven fabric raw material spinning

Next, a synthetic resin fiber (filter raw material) such as polyethylene, polypropylene, polyester, or polybutylene terephthalate is spun on the outer circumferential surface of the support to laminate the nonwoven filter.

That is, the chip-shaped synthetic resin fibers P are put into a known melt extruder 25, and the filter raw material extruded and melted by the melt extruder is stretched by compressed air at high temperature and high pressure, . Accordingly, the filter material is stacked on the outer circumferential surface of the support body 10 which is rotated and reciprocated by a certain distance from the left and right by the motor M to form a nonwoven filter.

At this time, since the filter raw materials sequentially laminated on the outer peripheral surface of the support 10 are in a slightly melted state, they are easily combined with each other.

In addition, the molten resin can be cooled to some extent by finely spraying water through the water injector 22 in the above-mentioned spinning process.

[3] blending of functional materials

Next, the functional material is sprayed together with moisture on the outer side of the synthetic resin fibers laminated on the outer circumferential surface of the support.

That is, the injection pump 32 of the injector is connected to the supply part 101 to receive the functional material and water. As the injection pump reciprocates, the functional material or the like is injected through the injection nozzle 31 of the injector into the outside of the synthetic resin fiber . As a result, the functional material in the form of beads is uniformly sprayed together with moisture and adhered to the filter raw material which is radiated to the support.

At this time, the injection process of [3] may be performed sequentially or concurrently with the spinning process of [2]. If the spinning process is followed by the spraying process, a functional material .

In addition, when water is finely sprayed to the synthetic resin fibers by the water spraying device 22 in the spinning process of [2], the functioning material may be sprayed together to double-coat the functional material, thereby further improving the metal ion removing function .

[4] deep filter forming

A nonwoven fabric filter having a metal ion removing function is obtained by the process of [2] and [3].

That is, as the spinning of the filter material by the radiator 20 and the injection of the functional material by the injector are performed sequentially or simultaneously, the functional material (I) is mixed between the filter materials to be laminated on the outer circumferential surface of the support Thereby forming a nonwoven filter.

Next, when the stacking of the filters is completed with a predetermined thickness, natural cooling or cooling air is supplied by air to rapidly dry the filter. At this time, the water spraying apparatus of [2] and the thermal spraying function of water sprayed by the sprayer of [3] So that the curing of the filter can be performed quickly.

When the filter raw material is radiated toward the outer peripheral surface of the support, the support is laminated from one side of the support. When the filter raw material is formed to have a constant thickness, it is sensed by a sensor provided adjacent to the support and is transported outward. A detailed description thereof will be omitted.

Thereafter, the nonwoven fabric filter cured to a predetermined strength is cut at a predetermined interval while being sent to the outside of the housing to form a cylindrical filter F.

FIGS. 3 and 4 each show a cross-section of a nonwoven fabric filter manufactured according to the present invention and a nonwoven fabric filter fabricated by a general manufacturing method. It can be seen from the figure that a functional material is applied between the filter material and the raw material.

INDUSTRIAL APPLICABILITY As described above, in the process of continuously producing a filter by directly spinning a raw material of a nonwoven fabric filter onto a cylindrical support, it becomes possible to manufacture a deep-drawn filter containing a functional material, that is, an ion exchange resin, inside the filter.
