Description

세척이 가능한 금속필터{Metel Filter} A metal filter capable of being cleaned (Metel Filter)

본 발명은 금속필터에 관한 것으로서, 더욱 상세히 설명하면 상·하부 캡 사이에는 여러 겹으로 포개진 여과망의 표면에 분리 가능한 불순물 흡착망이 씌어져 불순물을 여과하고, 상기 불순물 흡착망에 오일과 이물질이 포함된 불순물이 50% 이상 흡착되면 이를 여과망에서 분리한 다음 여과망은 세척하여 재사용하고 불순물 흡착망만 교체하는 방식으로 여러 번 재사용할 수 있는 금속필터에 관한 것이다.
More particularly, the present invention relates to a metal filter, and more particularly, a separable impurity adsorption net is provided on the surface of a filter net encapsulated in multiple layers between upper and lower caps to filter out impurities, The present invention relates to a metal filter which can be reused many times by separating the impurity contained therein more than 50% from the filter net and then washing and reusing the filter net and replacing only the impurity adsorption net.

일반적으로 설탕, 물엿을 유동성 용액을 포함하여 석유화학, 상·하수, 오·폐수, 지하수, 해수 등을 정수 처리하는데 사용되는 여과장치의 용기 내부에는 용액에 함유되어 있는 불순물(슬러지나 찌꺼기 등)을 걸러내기 위한 금속필터를 설치한다.Generally, impurities (such as sludge or residue) contained in a solution are contained in a container of a filtration apparatus used for water treatment of petrochemical, sewage, waste water, groundwater, seawater, etc., A metal filter is provided for filtering.

상기 금속필터는 금속망을 원통형상 또는 링 형상으로 절단하여 여과필터로 주로 사용한다.The metal filter is mainly used as a filtering filter by cutting a metal net into a cylindrical shape or a ring shape.

그러나 상기와 같이 구성되는 종래의 금속필터는 오일과 이물질을 포함한 불순물이 직접 흡착되기 때문에 세척이 불가능하여 통상 1회용으로 사용되는 것으로 한번 사용하게 되면 더 이상 재사용할 수 없어 새로운 금속필터로 교체하여 사용해야하므로 인해, 교체비용 및 교체시간이 낭비되는 비경제적인 문제점이 있었다.However, since the conventional metal filter constructed as described above can not be cleaned because impurities including oil and foreign matter are directly adsorbed, it can be used only once, and once it is used, it can not be reused anymore, There is an uneconomical problem that the replacement cost and the replacement time are wasted.

또한, 한번 사용된 종래의 여과재는 폐기시에도 별도의 비용이 소요될 뿐만 아니라 산업폐기물로써 환경오염의 원인이 되는 문제점이 있었다.In addition, the conventional filter material once used has an additional cost not only in disposal but also causes environmental pollution as industrial waste.

한편, 상기 금속필터의 실시 예를 설명하면 설탕의 제조는 사탕수수로 만들어진 원당을 수입해서 원당을 세척한 후, 설탕성분이 아닌 성분을 제거(정제)하고, 여과를 한다. In the meantime, a description will be made of an embodiment of the metal filter. In the production of sugar, a raw sugar made of sugar cane is imported, and the raw sugar is washed. Then, the sugar component is removed (refined) and filtered.

상기 여과를 마친 분말입자의 결정화 단계를 거치면 백설탕이 되고, 처음 생산된 백설탕의 정제과정이 계속되면 열에 의하여 설탕의 색이 갈색으로 변하게 되어 황백당, 흑설탕 등이 제조된다.When the filtrated powder particles are subjected to the crystallization step, the white sugar becomes white sugar. When the first white sugar produced is continuously refined, the color of sugar changes to brown by heat, so that yellow sugar, brown sugar and the like are produced.

따라서 설탕에 녹인 물을 여과할 때에는 여과 탱크 내부에는 여과장치로 금속필터를 삽입하여 설탕 녹인 물에 포함되어 있는 불순물을 여과하고, 상기 여과과정중 금속필터의 표면에는 오염물질인 불순물이 직접 흡착되어 시간이 경과 할수록 여과효율이 저하되어 금속필터를 교체해야하는 문제점이 있다.Therefore, when the water dissolved in sugar is filtered, a metal filter is inserted into the inside of the filtration tank to filter the impurities contained in the sugar dissolved water, and impurities, which are contaminants, are directly adsorbed on the surface of the metal filter during the filtration As the time passes, the filtration efficiency decreases and the metal filter needs to be replaced.

따라서 금속필터의 표면에는 50% 이상 불순물이 직접 흡착되어 있어 세척이 불가능한 문제점이 있다.
Therefore, there is a problem that impurities are directly adsorbed on the surface of the metal filter by 50% or more, which makes it impossible to clean.

상기와 같은 문제점을 해결하기 위한 본 발명은 불순물이 직접 흡착된 금속필터를 1회 사용 후 교체하지않고, 세척 후 재사용이 가능한 것을 목적으로 한다.
In order to solve the above problems, it is an object of the present invention to enable reuse after washing without replacing a metal filter in which impurities are directly adsorbed after a single use.

상기 과제의 해결수단으로 본 발명은 상·하부 사이에 위치하는 상·하부 캡사이에는 여러 겹으로 겹쳐진 원통형상의 여과망과, 상기 여과망중 외부 표면에는 교체 가능한 불순물 흡착망이 결합된 금속필터를 제공한다.
According to an aspect of the present invention, there is provided a metal filter in which a plurality of overlapping cylindrical filter nets are interposed between upper and lower caps positioned between upper and lower portions, and a replaceable impurity adsorption network is coupled to an outer surface of the filter network .

이상에서 설명한 바와 같이 본 발명 금속필터는 불순물이 50% 이상 흡착되는 표면에 교체 가능한 폴리프로필렌(Polypropylene) 재질의 불순물 흡착망을 결합하여 사용한 후 여과효율이 저하되면 불순물 흡착망은 분리하여 폐기하고, 금속재질의 여과망은 세척한 다음 불순물 흡착망만 교체하는 방식으로 금속필터를 40 ∼ 50회 이상 재사용이 가능한 효과가 있다.As described above, in the metal filter of the present invention, a replaceable polypropylene impurity adsorption net is used in combination with a surface adsorbing at least 50% of impurities, and if the filtration efficiency is lowered, the impurity adsorption net is separated and discarded, It is effective to reuse the metal filter more than 40 ~ 50 times by washing only the impurity adsorption net after cleaning the metal filter net.

또한, 본 발명은 불순물 흡착망의 성능을 통해 여과효율의 조절이 가능함은 물론 불순물 흡착망을 제외하고, 상·하부 캡에 고정된 나머지 여과망을 재사용이 가능하여 원가를 절감할 수 있는 효과가 있다.In addition, the present invention is capable of controlling the filtration efficiency through the performance of the impurity adsorption network, and reusing the remaining filter networks fixed to the upper and lower caps, except for the impurity adsorption network, thereby reducing the cost .

또한, 금속필터는 금속과 비금속을 혼합하여 내구성을 향상시키는 효과가 있다.
Further, the metal filter has an effect of improving durability by mixing metal and non-metal.
