본 고안은 물탱크에 관한 것으로서, 특히 물탱크 내부에 별도의 정수기 구성을 추가하여 고유의 저수기능은 물론 물의 정수기능도 수행할 수 있는 정수기능을 갖는 물탱크에 관한 것이다.The present invention relates to a water tank, and more particularly, to a water tank having a water purification function that can perform a water storage function as well as a unique water storage function by adding a separate water purifier configuration inside the water tank.
기존의 저수용 물탱크에는 자연적인 침전에 의한 정수기능이 있으나, 그 효과가 미비하여 거의 무시되는 상태이다.Conventional water storage tanks have a water purification function by natural precipitation, but the effect is insignificant and almost ignored.
또한 정수기는 일반적으로 실내에 설치하는 것으로서, 실내의 좁은 공간을 차지할뿐아니라 좁은 여과면적으로 인하여 불완전한 방법인 급속여과로 정수하는 것이 일반적인 방식이다.In addition, the water purifier is generally installed indoors, it is not only occupy a small space in the room, but the normal method is to purify by rapid filtration, which is an incomplete method due to the narrow filtration area.
본 고안은 이와같은 점을 고려하여 기존 물탱크의 침전기능을 강화시키고, 또한 물탱크의 넓은 면적을 이용하여 완벽한 완속여과를 실시함으로서 저수기능을 유지하는 상태에서 정수기능을 추가할 수 있는 정수기능을 갖는 물탱크를 제공하는데 그 목적이 있다.The present invention strengthens the sedimentation function of the existing water tank in consideration of such a point, and the water purification function that can add the water purification function while maintaining the water storage function by performing the perfect slow filtration using the large area of the water tank. The purpose is to provide a water tank having a.
이하, 본 고안을 첨부한 도면을 참고하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings of the present invention will be described in detail.
제 1 도는 본 고안의 정단면도로서, 편의상 내부구성을 단면처리하여 도시하였다.1 is a front sectional view of the present invention, and is shown by cross-sectional processing of the internal configuration for convenience.
일반적인 물탱크(1)의 저면에는 중공의 원추형 분리판(2)이 고착되며, 분리판(2)의 상단면은 개방된 상태이다.A hollow conical separator 2 is fixed to the bottom of the general water tank 1, and the top surface of the separator 2 is open.
물탱크(1) 하부는 이 분리판(2)에 의하여 침전조(1A) 저수조(1B) 및 여과조(1C)로 구분된다.The lower part of the water tank 1 is divided into the sedimentation tank 1A, the water storage tank 1B, and the filtration tank 1C by this separation plate 2.
즉, 분리판(2)의 외주부는 진자갈등의 하부여과재(3B)와 모래, 활성탄 및 무연탄 가루등의 상부여과재(3A)를 적층식으로 채움으로서 여과조(1C)로 형성하며, 분리판(2) 내부의 저부는 침전조(1A)로, 그 상부 및 분리판(2) 상부는 저수조(1B)로 각각 구별되어진다.That is, the outer periphery of the separating plate 2 is formed as a filtration tank 1C by filling the lower filter material 3B such as pendulum conflict and the upper filter material 3A such as sand, activated carbon and anthracite powder in a lamination manner, and separating plate 2 The inside of the bottom part is divided into a settling tank 1A, and the upper part and the upper part of the separating plate 2 are respectively divided into a reservoir 1B.
상부 여과재(3A)의 두께는 약 100cm정도가 적절하나 소형물탱크에서는 30∼40cm정도로 하며, 상부여과제(3A)를 지지하는 하부여과제(3B)는 약 15∼20cm 정도로 한다.The thickness of the upper filter medium 3A is preferably about 100 cm, but about 30 to 40 cm in the small water tank, and the lower filter 3B supporting the upper filter 3 A is about 15 to 20 cm.
상부여과재(3A)의 두께가 두꺼울수록 정수효과가 향상되나, 완속여과에서는 표면여과 작용이 크게 작용하므로 그 효과의 정도는 미미하다.The thicker the upper filter material 3A, the better the water purification effect. However, in slow filtration, the surface filtration effect is large, so the degree of the effect is insignificant.
한편, 하부여과재(3B)하단(물탱크(1)저면상)에는 분리판(2) 하단 외주면을 따라 도너츠형의 집수관(4)을 안착시키고, 그 일부에 T관(5)을 접속시킨다.On the other hand, at the lower end of the lower filter material 3B (on the bottom of the water tank 1), a donut-shaped collecting pipe 4 is seated along the outer circumferential surface of the bottom of the separating plate 2, and the T pipe 5 is connected to a part thereof. .
집수관(4)의 상부표면에는 다수의 집수공(4A)이 구성되며, 집수관(4)과 수직을 이루는 T관(5)은 물탱크(1)높이와 거의 동일하다. T관(5)의 분리판(2) 상단면보다 약간 높은 위치에는 정수공급관(5A)이 분기되어 물탱크(1) 외부로 연장된다. T관(5) 상단은 개방된 상태로서 물탱크(1) 내부의 수면상으로 노출된다.The upper surface of the water collecting pipe 4 is composed of a plurality of water collecting holes 4A, and the T pipe 5 perpendicular to the water collecting pipe 4 is almost equal to the height of the water tank 1. At a position slightly higher than the upper surface of the separation plate 2 of the T pipe 5, the purified water supply pipe 5A is branched to extend outside the water tank 1. The upper end of the T pipe 5 is open and exposed on the surface of the water tank 1.
물탱크(1) 내부 상부에는 원수(源水)가 공급되는 볼탭함(6)이 설치되어 있으며, 볼탭함(6) 하부에는 정류관(7)이 연결되어 그 단부가 분리판(2) 상부에 위치한다.In the upper part of the water tank (1), a ball tap box (6) for supplying raw water is installed. Located.
또한, 정류관(7) 하단에는 원추형 정류통(8)이 연결된다.In addition, a conical rectifier (8) is connected to the bottom of the rectifying pipe (7).
따라서 볼탭함(6)과 정류통(8)은 정류관(7)에 의하여 연통되며, 정류통(8)은 분리판(2) 내부에 위치하게 된다. 정류통(8)은 그 하단이 물탱크(1) 저면에서 4∼10cm정도 이격된 상태로 고정된다.Therefore, the ball tap box 6 and the rectifier 8 are communicated by the rectifier tube 7, the rectifier 8 is located inside the separation plate (2). The rectifier 8 is fixed to the bottom of the water tank (1) spaced apart about 4 ~ 10cm.
한편, 분리판(2) 하단의 일측부에는 별도의 파이프(9)를 분기시켜 하부여과재(3B)를 가로질러 물탱크(1) 외부로 노출시킴으로서, 분리판(3B)를 가로질러 물탱크(1) 외부로 노출시킴으로서, 분리판(2, 침전조(1A))내의 여과되지 않은 물(불순물의 1차 침전은 이루어짐)을 식수가 아닌 용도로 사용할 수 있도록 한다.On the other hand, one side of the bottom of the separating plate (2) by branching a separate pipe (9) to expose the outside of the water tank (1) across the lower filter material (3B), across the separation plate (3B) 1) By exposing to the outside, unfiltered water (primary precipitate of impurity) in the separator (2, sedimentation tank (1A)) can be used for non-drinking water.
또한 집수관(4) 하단 일측부에 별도의 배수관(4B)을 구성하여 여과조(1C) 및 집수관(4)내의 정수된 물을 비상식수로서 사용할 수 있다.In addition, a separate drain pipe 4B is formed at one lower end of the collecting pipe 4 so that the purified water in the filtration tank 1C and the collecting pipe 4 can be used as emergency drinking water.
이상과 같은 구성을 갖는 본 고안의 기능을 설명하면, 외부수원에서 공급되어 볼탭함(6)에 저장된 원수는 물탱크(1)내의 수위에 따라 작동하는 볼탭(6A)의 작용에 의하여 정류관(7) 및 정류통(8)을 거쳐 분리판(2) 내부로 유입된다.Referring to the function of the present invention having the configuration as described above, the raw water supplied from the external water source and stored in the ball tap box 6 is rectified by the action of the ball tap (6A) in accordance with the water level in the water tank (1) And into the separator 2 through the rectifier 8.
외부수원에서 공급되어 볼탭함(6)에 저장된 원수는 물탱크(1)내의 수위에 따라 작동하는 볼탭(6A)의 작용에 의하여 정류관(7) 및 정류통(8)을 거쳐 분리판(2) 내부로 유입된다.The raw water supplied from the external water source and stored in the ball tap box 6 is separated through the rectifying pipe 7 and the rectifying tube 8 by the action of the ball tap 6A acting according to the water level in the water tank 1. Flows inside.
정류통(8)으로 유입되는 물은 정류통(8)이 하부로 갈수록 그 단면적이 넓어지는 구조이기 때문에 유속이 감소되며, 따라서 원수에 함유되어 있는 부유고형물(Suspend Solid)은 분리판(2) 하부의 침전조(1A)바닥(물탱크(1)저면)에 침전된다.Water flowing into the rectifier (8) is reduced in flow rate because the cross-sectional area of the rectifier (8) toward the bottom wider, so the suspended solids contained in the raw water (Suspend Solid) is separated from the separator (2) It precipitates in the bottom of 1A of sedimentation tanks (bottom of the water tank 1) of a lower part.
분리판(2) 내부에서 부유고형물이 1차적으로 침전된 원수는 계속적인 원수의 공급으로 인하여 여과조(1C)로 상승, 유입되어 상부여과부재(3A)와 하부여과부재(3B)를 거쳐 최종적인 여과기능이 이루어진다.The raw water in which the suspended solids are primarily precipitated in the separating plate 2 rises and flows into the filtration tank 1C due to the continuous supply of raw water, and finally passes through the upper filtration member 3A and the lower filtration member 3B. Filtration is achieved.
여과조(1C) 상부로 유입된 원수는 물은 상부여과재(3A)와 하부여과재(3B)를 순차적으로 통과하여 집수관(4)에 도달한다.The raw water introduced into the upper part of the filtration tank 1C sequentially passes through the upper filter material 3A and the lower filter material 3B to reach the collection pipe 4.
이 과정을 거치는 동안 물은 상, 하부 여과재(3A, 3B)에 의하여 여과되며, 따라서 침전과 여과의 정수작용을 거친 원수는 집수관(4)의 상부표면에 구성된 다수의 집수공(4A)을 통하여 집수관(4)내로 유입된다.During this process, the water is filtered by the upper and lower filter media (3A, 3B), so that the raw water, which has undergone the water purification of sedimentation and filtration, collects a plurality of collecting holes (4A) formed on the upper surface of the collecting pipe (4). It is introduced into the collecting pipe (4) through.
집수관(4)내의 물은 그일측부에 연결시킨 T관(5)내로 유입, 상승된다. T관(5) 상단은 개방된 상태이므로 정수가 완료된 T관(5)내의 물은 물탱크(1)내의 수위(분리판(2)내부에서 1차 침전이 완료된 상태)와 동일한 수위를 갖는다.Water in the collecting pipe 4 flows into and rises into the T pipe 5 connected to one side thereof. Since the upper end of the T pipe 5 is in an open state, the water in the T pipe 5 in which the purified water is completed has the same water level as the water level in the water tank 1 (the state in which the primary sedimentation is completed in the separator 2).
따라서 T관(5)내에 저장된 정수된 물은 중앙부 일측에 구성된 정수공급관(5a)를 통하여 외부로 인출가능하게 된다.Therefore, the purified water stored in the T pipe 5 can be taken out through the purified water supply pipe 5a configured at one side of the central portion.
이 정수공급관(5A)은 여과조(1B) 표면(상부여과재(3A)표면)보다 약간 높게 위치하도록 구성하여 물탱크(1)내의 수위가 여과조(1C)표면이하로 내려가지 못하도록 한다. 즉, 정수된 물의 사용에 의하여 T관(5)내의 수위가 정수공급관(5A) 이하로 떨어질 경우 정수의 배출은 이루어지지 않으며, 이때 물탱크(1) 내부의 수위도 여과조(1C) 표면보다 높게 위치하게 된다.The purified water supply pipe 5A is configured to be positioned slightly higher than the surface of the filtration tank 1B (the surface of the upper filter material 3A) to prevent the water level in the water tank 1 from falling below the surface of the filtration tank 1C. That is, when the water level in the T pipe 5 falls below the purified water supply pipe 5A by the use of purified water, the purified water is not discharged, and the water level inside the water tank 1 is also higher than the surface of the filtration tank 1C. Will be located.
따라서, 상부여과재(3A)는 노출된 상태가 이루어지지 않으므로 분리판(2) 내부에서 공급되는 원수로 인하여 상부여과재(3A) 표면에서 자연적으로 형성되는 여과막의 파괴를 방지할 수 있다.Therefore, since the upper filter material 3A is not exposed, it is possible to prevent destruction of the filtration membrane naturally formed on the surface of the upper filter material 3A due to the raw water supplied from the inside of the separator 2.
여기서, 여과막은 원수에 함유되어 있는 유기물에 의하여 상부여과재(3A)표면에서 퇴적되는 것으로, 침전이 완료된 원수가 상부여과재(3A)내로 스며들기전에 이 여과막에 의하여 1차적인 여과가 선행된다.Here, the filtration membrane is deposited on the surface of the upper filter material 3A by the organic matter contained in the raw water, and the primary filtration is preceded by the filtration membrane before the precipitated raw water penetrates into the upper filter material 3A.
본 고안을 구성하는 각부재의 구성적 특징을 설명하면, 분리판(2)을 원뿔대형으로 구성한 이유는 침전조(1A, 분리판(2)내의 물탱크 저면)와 여과조(1C)의 구성면적을 넓게 형성하기 위함이다.When explaining the structural features of each member constituting the present invention, the reason for the configuration of the separation plate 2 in a truncated conical shape is the area of the settling tank (1A, the bottom of the water tank in the separation plate 2) and the filtration tank (1C). To form a wide.
한편, 정류관(7)에 연결된 정류통(8)을 하부의 직경이 점차 증가되는 원뿔형으로 구성함으로서, 정류관(7)을 따라 유입된 원수는 점차적으로 면적으로 증가되는 정류통(8) 내부에서 그 유속이 감소되므로 분리판(2)내의 수위는 점차적으로 상승되어 여과조(1C)표면(상부여과재(3A) 표면)에 퇴적된 여과막의 흐트러짐을 방지한다.On the other hand, by composing the rectifying tube (8) connected to the rectifying tube (7) in a conical shape of which the diameter of the lower portion gradually increases, the raw water introduced along the rectifying tube (7) is gradually increased in the area within the rectifying tube (8) Since the flow rate is reduced, the water level in the separating plate 2 is gradually raised to prevent the filtration membrane deposited on the surface of the filtration tank 1C (surface of the upper filter material 3A).
또한 분리판(2) 저부에 퇴적된 부유고형물(Suspend Solid)의 퇴적상태를 유지할 수도 있다.In addition, it is possible to maintain the deposited state of the suspended solid (Suspend Solid) deposited on the bottom of the separator (2).
이 부유고형물은 침전기능을 수행하며, 부유 고형물의 퇴적층에 원수에 함유된 또 다른 부유고형물에 대한 흡착작용을 수행하므로 침전작용을 촉진시킨다.The suspended solids perform the settling function and promote the settling action by performing the adsorption action on another suspended solids contained in the raw water in the sedimentation layer of the suspended solids.
여과조(1C) 표면 즉, 상부여과재(3A) 표면에 퇴적된 여과막의 두께가 너무 두꺼울 경우 분리판(2)에서 상승, 유입된 원수가 상, 하부 여과재(3A, 3B)로 통수되지 못하므로 사용과정에서 세척은 하여야 한다.If the thickness of the filtration membrane deposited on the surface of the filter tank 1C, that is, the upper filter material 3A is too thick, the raw water that rises and flows from the separator 2 cannot pass through the upper and lower filter media 3A and 3B. The process must be cleaned.
세척방법은 상부여과재(3A)의 표면을 일부두께(약 1cm) 걷어내는 흐르는 물에 세척을 한 뒤, 다시 채움으로서 이루어진다.The washing method is performed by washing the surface of the upper filter material 3A with running water to remove a part of thickness (about 1 cm) and then refilling it.
본 고안의 세척주기는 일반적인 완속여과와는 달리 약30일 간격을 두는 것이 비실용적이다.Unlike the general slow filtration cycle of the present invention, it is impractical to leave an interval of about 30 days.
본 고안은 침전조(1A, 분리판 내부저면)에서 완벽한 침전이 이루어진후 여과가 이루어지므로 여과조의 부하가 감소되며, 식수등의 같은 특별히 청결을 필요로 하는 물만 여과시키므로 세척기간을 수백일 정도로 연장시킨 것이다.The present invention reduces the load of the filtration tank because the filtration is performed after complete precipitation in the settling tank (1A, bottom of the separator), and only the water requiring special cleanness such as drinking water is extended to extend the washing period to several hundred days. will be.
본 고안은 어떠한 형태의 물탱크에는 응용할 수 있으나, 여과재의 두께를 충분히 유하기 위해서는 입치원통형 물탱크에 가장 적합하게 실시할 수 있다.The present invention can be applied to any type of water tank, but in order to sufficiently maintain the thickness of the filter medium, it can be most suitably carried out in a standing cylindrical water tank.
본 고안에서 상부여과재의 두께를 중요시하는 것은 여과막에 의하여 1차 여과된 물은 상부여과재에 의하여 세균등의 여과작용이 이루어지기 때문이다.The importance of the thickness of the upper filter material in the present invention is because the primary filtered water is filtered by the upper filter material, such as bacteria.
원수를 여과막 및 상부여과재를 거쳐 완속여과시키는 본 고안은 부유고형물과 세균을 거의 완전히 제거시킬 수 있으며, 물탱크의 저수작용으로 인하여 THM(트리 할로 메탄)등 원수에 함유되어 있는 유해 휘발성분은 감소시킬 수 있다.The present invention, which slows the filtration of raw water through the filtration membrane and the upper filter material, can almost completely eliminate suspended solids and bacteria, and the toxic volatiles contained in raw water such as THM (trihalo methane) are reduced due to the water action of the water tank. You can.
이상과 같은 본 고안은 물탱크의 저수기능에 영향을 끼치지 않으면서도 일반적인 정수기의 기능을 추가시킴으로서 위생상 좋을 뿐만 아니라 2가지 기능을 물탱크가 복합적으로 수행하므로 경제적인 효과도 얻을 수 있다.The present invention as described above is not only good for hygiene by adding the function of the general water purifier without affecting the water storage function of the water tank, as well as economical effect can be obtained because the water tank performs a combination of the two functions.
