Description

Technology Field

[0001] The present invention relates to a PLA multi-nanomembrane filter and a method for manufacturing the same, and in particular to a PLA multi-nanomembrane filter and a method for manufacturing the same that increases the water purification effect by increasing the temperature of a specific part to reduce the diameter of the filter material. Background Technology

[0002] As modern people's living standards steadily improve, their interest in health is also rising relatively. In particular, interest in drinking water, which is most closely related to human life, is increasing, and the market for it is also expanding.

[0003] Generally, drinking water is broadly divided into cases where water is purchased as pre-purified water, groundwater, or bottled water, and cases where it is purified directly using a water purifier.

[0004] However, recently, due to severe groundwater contamination and frequent contamination of bottled water sold by companies, there is a growing trend of people using water purifiers directly. With this increased interest in water, while water purifiers were previously used only for drinking water, their scope of use has gradually expanded, leading to the use of purified water for cooking in the kitchen as well.

[0005] Generally, filters are divided into water purifier filters and industrial filters. However, since these filters are primarily devices used for filtering, adsorbing, ion-exchanging, and sterilizing domestic or industrial water, their operating principles are similar.

[0006] These filters include sediment filters, activated carbon filters, hollow fiber membrane filters, ion exchange resin filters, and reverse osmosis filters. Among them, the sediment filter serves to filter out particulate residue contained in water before purification (hereinafter referred to as 'raw water').

[0007] In other words, the sediment filter is a pretreatment sedimentation filter that filters out foreign substances such as rust, soil, sand, dust, and various debris and oxides contained in the raw water, and is installed behind the main filter to provide an important function of ensuring the normal operation of all parts or filters that come into contact with water.

[0008] Conventional sediment filters are mostly provided in a pipe shape or a cylindrical shape as shown in Fig. 1, and their thickness and length are standardized depending on whether they are for water purifiers or industrial use. However, since water flows in the thickness direction of the sediment filter to filter out debris contained in the water, it is generally designed to have a large thickness. This increased material costs, which caused the unit price of the product to rise.

[0009] As related prior art, there is Korean Published Patent Application No. 10-2015-0065293 (published on June 15, 2015), and the said prior art discloses technology regarding a water purifier filter structure. The problem to be solved

[0015] It includes a step in which a hollow portion is formed as the molded filter moves by a screw formed on one side of the above rod.

[0016] Air and resin are input into the above heater device from the top, heated by the heat of the internal heater, and output through the outlet as a thin thread-shaped filter material.

[0017] The step of supplying filter material to multiple outlets through a heater device having the above-mentioned plurality of heaters is:

[0030] FIG. 2 is a drawing showing a method for manufacturing a PLA multi-nanomembrane filter according to an embodiment of the present invention, and FIG. 3 to 6 are drawings for explaining a method for constructing an insulating material according to an embodiment of the present invention.

[0031] Referring to FIGS. 2 to 6, a PLA multi-nanomembrane filter according to an embodiment of the present invention has a hollow formed in a cylindrical body (300), and at least one tree ring shape (310, 320) is formed on the cross-section of the cylinder.

[0033] The above tree ring shape (310, 320) is formed by maintaining the temperature of the two middle heaters among the six heaters of the heater device (200) high so that the diameter of the filter material is 0.5 to 1 micrometer and wound on the rod (110), and can be seen as a tree ring shape (310, 320) with the naked eye.

[0034] In this invention, Polylactic Acid (PLA) nanofibers are used to improve the water purification performance of the filter by being biodegradable, eco-friendly, and possessing inherent antimicrobial properties. PLA decomposes rapidly under industrial composting conditions and does not generate harmful chemicals during this process, thereby significantly reducing the environmental burden. Unlike conventional petroleum-based plastics, PLA generates almost no harmful gases other than carbon dioxide even when incinerated, thus contributing to the reduction of greenhouse gases.

[0035] The method for manufacturing a PLA multi-nanomembrane filter according to an embodiment of the present invention having such a configuration is as follows.

[0036] Referring to FIGS. 2 and FIGS. 3, first, a step (S310) of supplying filter material to a plurality of outlets (220) through a heater device (200) having a plurality of heaters is performed.

[0037] Here, air and resin are input into the upper inlet (210) of the heater device (200), the resin is heated by six internal heaters, and is output as a thin thread-shaped filter material through the outlet (220).

[0038] At this time, the temperature of the second and fifth heaters of the heater device (200) is maintained at 300°C, and the diameter of the filter material of the outlet (220) corresponding to the second and fifth heaters is maintained at 0.5 to 1 micrometer.

[0039] And the temperature of the 1st, 3rd, 4th, and 6th heaters of the heater device (200) is maintained at 200°C, and the diameter of the filter material of the outlet (220) corresponding to the 1st, 3rd, 4th, and 6th heaters is maintained at 10 to 20 micrometers.

[0040] Next, a step (S320) is performed in which a filter is formed by rotating a rod (110) connected to a motor, using the filter material supplied to the plurality of outlets (220).

[0041] Referring to FIG. 4 or FIG. 5, a filter (300) having a certain thickness is formed as the filter material is wound around a rod (110). At this time, at least one tree ring shape (310, 320) is formed on the side cross-section of the cylindrical filter (300).

[0042] The above tree ring shape (310, 320) is formed by maintaining the temperature of the two middle heaters among the six heaters of the heater device (200) high, so that the diameter of the filter material is 0.5 to 1 micrometer and wound around the rod (110), and can be seen as a tree ring shape (310, 320) with the naked eye. If necessary, the number of heaters of the heater device (200) and the temperature or the number of heaters that maintain a high temperature can be modified.

[0043] Next, a step (S330) is performed in which the molded filter (300) is moved by a screw (120) formed on one side of the rod (110) to form a hollow portion.

[0044] Referring to FIG. 5 or FIG. 6, the filter (300) that has been moved after the molding is completed has a hollow formed therein, and a tree ring shape (310, 320) is formed on the side cross-section.

[0045] Therefore, the filter (300) has two parts where the diameter of the filter material is very small, so the water purification effect is excellent.

[0046] As such, in an embodiment of the present invention, the water purification effect of the filter can be enhanced by manufacturing a filter by increasing the temperature of some of the heaters among a plurality of heaters to reduce the diameter of the filter material.

[0047] In addition, in an embodiment of the present invention, a filter is manufactured in a rotary manner using a driving motor and a screw, and the water purification effect can be enhanced by manufacturing the filter with the diameter of the filter material maintained at 0.5 to 1 micrometer by maintaining the temperature of the two middle heaters among the six heaters at a high level.

[0048] One embodiment of the disclosed technology has been described with reference to the embodiment illustrated in the drawings for the sake of understanding, but this is merely illustrative and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the disclosed technology should be determined by the appended claims.
