Description

도트형 홀이 형성된 원통형 필터{Cylindrical filter having hole}Cylindrical filter having a dot-shaped hole

본 발명은 도트형 홀이 형성된 원통형 필터에 관한 것으로서, 보다 상세하게는 외주면에 도트형 홀이 형성되어 여과효율이 향상되고 수명도 연장되는 새로운 구성의 도트형 홀이 형성된 원통형 필터가 관한 것이다.The present invention relates to a cylindrical filter with dot-shaped holes, and more specifically, to a cylindrical filter with dot-shaped holes of a new configuration in which dot-shaped holes are formed on the outer peripheral surface to improve filtration efficiency and extend lifespan.

액체용 필터로 흔히 원통형 필터가 사용되는데, 원통형 필터는 통공이 형성된 심재에 부직포를 권취하여 형성된다. Cylindrical filters are commonly used as filters for liquids, and the cylindrical filter is formed by winding a non-woven fabric around a core material with holes.

그런데, 이러한 원통형 필터를 사용하여 액체를 여과하는 경우에, 액체 즉, 피처리물에 의해 필터에 열과 압력이 가해지면, 필터를 이루는 부직포가 열에 의해 융착되거나 압력에 의해 눌려서 필터의 형태가 변형되어 필터가 손상된다. 따라서 필터의 여과효율이 현저하게 저하되므로 필터를 비교적 자주 교체해주어야 하는 문제점을 가진다. However, when filtering a liquid using such a cylindrical filter, when heat and pressure are applied to the filter by the liquid, that is, the object to be treated, the nonwoven fabric making up the filter is fused by heat or pressed by pressure, deforming the shape of the filter. The filter is damaged. Therefore, since the filtration efficiency of the filter is significantly reduced, there is a problem in that the filter must be replaced relatively frequently.

대한민국 공개특허 제10-2009-0075490호(2009. 07. 08.)Republic of Korea Patent Publication No. 10-2009-0075490 (2009. 07. 08.) 대한민국 등록특허 제10-0322959호(2002. 01. 21.)Republic of Korea Patent No. 10-0322959 (January 21, 2002)

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 외주면에 도트형 홀이 형성되어 표면적이 증가되고 도트형 홀에서 피여과물의 미세 와류가 형성되어 여과효율이 향상되며, 내구성이 향상되어 수명도 연장되는 새로운 구성의 도트형 홀이 형성된 원통형 필터를 제공하는 것이다.The present invention is to solve the above problems. The purpose of the present invention is to increase the surface area by forming a dot-shaped hole on the outer peripheral surface, and to improve filtration efficiency and durability by forming a fine vortex of the filtrate in the dot-shaped hole. The aim is to provide a cylindrical filter with dot-shaped holes of a new configuration that extends the lifespan.

본 발명의 특징에 따르면, 열가소성 수지로 이루어진 부직포를 다수회 권취하여 이루어진 필터부(20)를 포함하며, 상기 필터부(20)의 외주면에는 도트형 홀(22)들이 배열형성된 것을 특징으로 하는 도트형 홀이 형성된 원통형 필터가 제공된다.According to a feature of the present invention, it includes a filter unit 20 made of a non-woven fabric made of thermoplastic resin wound multiple times, and dot-shaped holes 22 are arranged on the outer peripheral surface of the filter unit 20. A cylindrical filter having shaped holes is provided.

본 발명의 다른 특징에 따르면, 상기 부직포는 외측면에 도트형 홀(22)이 형성되며, 상기 필터부(20)의 내부에도 상기 도트형 홀(22)들이 형성된다.According to another feature of the present invention, the nonwoven fabric has dot-shaped holes 22 formed on the outer surface, and the dot-shaped holes 22 are also formed inside the filter unit 20.

이상과 같은 구성의 본 발명은 필터부(20) 외주면에 형성된 도트형 홀(22)에 의해 필터부(20)의 표면적이 증가되고, 아울러 도트형 홀(22)에서 피여과물인 유체의 미세 와류가 형성되어 유체와의 접촉면적이 증가되어 여과효율이 향상된다. In the present invention with the above configuration, the surface area of the filter unit 20 is increased by the dot-shaped hole 22 formed on the outer peripheral surface of the filter unit 20, and in addition, the fine vortex of the fluid to be filtered is generated in the dot-shaped hole 22. This increases the contact area with the fluid and improves filtration efficiency.

또한, 도트형 홀(22)에 의해 필터부(20)의 내구성이 향상되어 필터부(20)의 변형이 방지되므로 필터의 수명도 연장된다. 따라서 필터를 자주 교체하여야 하는 번거로움도 해소되고, 필터교체비용도 절감된다. In addition, the durability of the filter unit 20 is improved by the dot-shaped hole 22 and deformation of the filter unit 20 is prevented, thereby extending the life of the filter. Therefore, the inconvenience of frequently replacing filters is eliminated, and filter replacement costs are also reduced.

이하에서 도면을 참조하여 본 발명을 구체적으로 설명한다. Hereinafter, the present invention will be described in detail with reference to the drawings.

도 1과 도 2는 본 발명의 제1실시예의 사시도 및 측단면도이다. 본 발명은 도시된 바와 같이, 통공(12)이 형성된 원통형 심재(10)와, 심재(10)에 부직포를 권취하여 이루어진 필터부(20)와, 상기 필터부(20)의 외주면에 소정형태로 배열형성된 도트형 홀(22)을 포함하여 이루어진다.1 and 2 are a perspective view and a side cross-sectional view of the first embodiment of the present invention. As shown, the present invention includes a cylindrical core material 10 with a through hole 12 formed, a filter portion 20 formed by winding a non-woven fabric around the core material 10, and a filter portion 20 formed in a predetermined shape on the outer peripheral surface of the filter portion 20. It includes arrayed dot-shaped holes 22.

상기 심재(10)는 원통형상으로 되어 내부로 통수가 가능하도록 통공(12)이 형성된다. 이러한 심재(10)는 금속으로 이루어진다. The core material 10 has a cylindrical shape and a through hole 12 is formed to allow water to pass through the inside. This core material 10 is made of metal.

상기 필터부(20)는 폴리에틸렌, 폴리프로필렌, 폴리아미드 등과 같은 열가소성 수지로 이루어진 부직포를 심재(10) 외주면에 다수 회 권취하여 소정두께로 형성된다. 여과효율을 고려할 때 필터부(20)는 멜트브라운 부직포를 권취하여 이루어지는 것이 바람직하다. The filter unit 20 is formed to a predetermined thickness by winding a non-woven fabric made of thermoplastic resin such as polyethylene, polypropylene, polyamide, etc. multiple times around the outer peripheral surface of the core material 10. Considering filtration efficiency, it is preferable that the filter unit 20 is formed by winding melt brown nonwoven fabric.

한편, 이와 같이 형성된 필터부(20)의 외주면에는 도트형 홀(22)이 소정 형태로 배열형성된다. 이와 같이 필터부(20)에 도트형 홀(22)이 형성되면 필터부(20)의 표면적이 증가되며, 아울러 도트형 홀(22)에서 피여과물인 유체가 도트형 홀(22)안으로 돌면서 빨려 들어가게 되어 도트형 홀(22)에서 유체의 미세 와류가 형성되므로 유체와의 접촉면적이 증대되어 여과효율이 향상된다. 뿐만 아니라, 도트형 홀(22)에 의해 필터부(20)의 내구성이 향상되어 필터부(20)의 변형이 방지되며, 이에 따라 필터의 수명도 연장된다.Meanwhile, dot-shaped holes 22 are arranged in a predetermined shape on the outer peripheral surface of the filter unit 20 formed in this way. In this way, when the dot-shaped hole 22 is formed in the filter unit 20, the surface area of the filter unit 20 increases, and in addition, the fluid to be filtered in the dot-shaped hole 22 rotates and is sucked into the dot-shaped hole 22. As a result, a fine vortex of fluid is formed in the dot-shaped hole 22, thereby increasing the contact area with the fluid and improving filtration efficiency. In addition, the durability of the filter unit 20 is improved by the dot-shaped hole 22, preventing deformation of the filter unit 20, and thereby extending the life of the filter.

이러한 도트형 홀(22)은 바람직하게는 반구형이나 반타원형 등과 같이 내주면이 곡면으로 이루어진 형상으로 소정 깊이 함몰되는데, 도트형 홀(22)이 이러한 형상을 가지면 도트형 홀(22)에서 유체의 와류가 좀 더 효과적으로 형성될 것으로 기대된다. 한편, 도트형 홀(22)이 과도하게 크면 필터부(20)의 표면적증대 효과가 미미하고, 반대로 도트형 홀(22)이 과도하게 작으면 미세 와류의 형성효과가 저하되어 여과효율의 상승을 기대하기 곤란해진다. 따라서 이러한 점을 고려하여 도트형 홀(22)의 크기는 필터의 용도에 따라 적절히 조절되는데, 도트형 홀(22)은 대략 직경은 1~2mm, 깊이는 1~2mm 정도의 크기로 형성된다. These dot-shaped holes 22 are preferably sunken to a predetermined depth in a shape in which the inner peripheral surface is curved, such as a hemisphere or a semi-elliptical shape. If the dot-shaped hole 22 has this shape, a vortex of fluid occurs in the dot-shaped hole 22. is expected to be formed more effectively. On the other hand, if the dot-shaped hole 22 is excessively large, the effect of increasing the surface area of the filter unit 20 is minimal, and conversely, if the dot-shaped hole 22 is excessively small, the effect of forming fine vortices is reduced, thereby reducing the increase in filtration efficiency. It becomes difficult to expect. Therefore, taking this into consideration, the size of the dot-shaped hole 22 is appropriately adjusted depending on the purpose of the filter. The dot-shaped hole 22 is formed to have a diameter of approximately 1 to 2 mm and a depth of 1 to 2 mm.

이러한 구성을 가지는 본 발명은 다음과 같은 방법으로 제조된다.The present invention having this configuration is manufactured by the following method.

회전봉에 통공(12)이 형성된 심재(10)를 끼우고, 심재(10)에 부직포를 소정 두께로 권취하여 필터부(20)를 형성시키는데, 부직포를 권취하면서 부직포의 권취된 층들이 상호 융착되므로 열을 가하여 필터부(20)의 권취된 상태가 유지되도록 한다. The core material 10 having the through hole 12 is inserted into the rotating rod, and non-woven fabric is wound to a predetermined thickness around the core material 10 to form the filter unit 20. As the non-woven fabric is wound, the wound layers of the non-woven fabric are fused together. Heat is applied to maintain the wound state of the filter unit 20.

이와 같이 하여 원하는 두께의 필터부(20)를 형성시킨 다음, 엠보싱돌기가 형성된 엠보싱롤러로 필터부(20)의 외주면를 가압가열한다. 이와 같이 하면 필터부(20)의 외주면에 상기 엠보싱돌기에 대응되는 형상으로 함몰된 도트형 홀(22)이 형성된다. 이어서 필터부(20)를 냉각시킨 다음, 상호 부착된 심재(10)와 필터부(20)를 히팅봉에서 분리하고 소정 길이로 절단하여 필터를 완성한다. After forming the filter unit 20 with the desired thickness in this way, the outer peripheral surface of the filter unit 20 is heated and pressed using an embossing roller on which embossing protrusions are formed. In this way, a dot-shaped hole 22 recessed into a shape corresponding to the embossed protrusion is formed on the outer peripheral surface of the filter unit 20. Next, the filter unit 20 is cooled, and then the core material 10 and the filter unit 20 that are attached to each other are separated from the heating rod and cut to a predetermined length to complete the filter.

본 실시예에서는 필터부(20) 내부에 심재(10)가 구비된 것으로 예시되었으나, 심재(10)가 생략될 수도 있다. 도 3은 본 발명의 제2실시예의 사시도로서, 본 실시예에서는 필터부(20) 내부에 심재가 구비되지 않는다. 이러한 본 실시예는 회전봉에 직접 부직포를 권취하여 필터부(20)가 형성된다. In this embodiment, it is illustrated that the core material 10 is provided inside the filter unit 20, but the core material 10 may be omitted. Figure 3 is a perspective view of the second embodiment of the present invention. In this embodiment, no core material is provided inside the filter unit 20. In this embodiment, the filter unit 20 is formed by winding the nonwoven fabric directly on the rotating rod.

이하에서는 본 발명의 다른 실시예를 설명하되, 전술한 실시예와 동일한 구성 및 효과에 대해서는 설명을 생략한다.Hereinafter, another embodiment of the present invention will be described, but description of the same configuration and effect as the above-described embodiment will be omitted.

도 4는 본 발명의 제3실시예의 평단면도이다. 본 실시예에서는 도시된 바와 같이, 필터부(20)의 외주면 뿐만 아니라 필터부(20) 내부에도 도트형 홀(22)이 형성된다. Figure 4 is a plan cross-sectional view of a third embodiment of the present invention. In this embodiment, as shown, dot-shaped holes 22 are formed not only on the outer peripheral surface of the filter unit 20 but also inside the filter unit 20.

본 실시예에서는 일측 면에 도트형 홀(22)이 형성된 부직포를 도트형 홀(22)이 형성된 면을 외향으로 향하도록 권취하여 필터부(20)가 형성된다. 따라서 필터부(20)의 외주면에 도트형 홀(22)이 형성되는 것은 물론이며, 필터부(20)의 내부 즉, 부직포의 권취된 층 사이에도 도트형 홀(22)이 형성된다. In this embodiment, the filter portion 20 is formed by winding a nonwoven fabric with dot-shaped holes 22 formed on one side so that the side on which the dot-shaped holes 22 are formed faces outward. Therefore, not only are the dot-shaped holes 22 formed on the outer peripheral surface of the filter unit 20, but the dot-shaped holes 22 are also formed inside the filter unit 20, that is, between the wound layers of the nonwoven fabric.

이와 같이 본 실시예는 필터부(20)의 외주면과 더불어 필터부(10)의 내부에도 도트형 홀(22)이 형성되므로 유체와의 접촉면적이 한층 더 증가되며, 필터부 내부에서도 유체의 미세 와류가 형성되기 때문에 여과효율이 한층 더 효과적으로 향상된다.As such, in this embodiment, the dot-shaped hole 22 is formed not only on the outer peripheral surface of the filter unit 20 but also on the inside of the filter unit 10, so that the contact area with the fluid is further increased, and even within the filter unit, the fine particles of the fluid are formed. Because vortices are formed, filtration efficiency is further improved.
