Description
본 고안은 수세식 화장실로부터 분(糞)과 함께 방류되는 변오수(便汚水) 중 뇨(尿)와 세정수(洗淨水) 만을 정화하여 방류하고 분(糞)은 호기성세균의 분해작용에 의해 처리하여 저장하기 위한 정화조에 있어서 그 통체를 일체로 성형하기 위한 정화조통체 성형용 금형에 관한 것이다.The present invention purifies and discharges only urine and washing water out of the filthy water discharged from the flush toilet together with powder, and the powder is decomposed by aerobic bacteria. A septic tank body molding die for integrally molding the cylinder in a septic tank for treatment and storage.
정화조 중 분뇨를 처리하기 분뇨정화조는 빗물, 부엌, 세면장 등의 잡배수를 혼입시키지 않고 수세식의 화장실로부터 배출되는 변과 오수만를 처리하기 위한 장치로 널리 이용되고 있다.Treatment of Manure in Septic Tanks Manure septic tanks are widely used as devices for treating feces and sewage discharged from flush toilets without mixing wastewater such as rainwater, kitchens, and washrooms.
그리고 대부분의 경우 소형의 분뇨정화조는 도 4에 도시된 바와 같이 원형의 통 형상인 직립통체(101)의 상부에 덮개(102)가 결합되고 직립통체(101)의 하부에는 바닥판(103)이 결합된 구성의 통체(100) 내에 산화조(104) 및 살수판(105) 등의 내부 구성물이 설치되고 또 직립통체(101)에는 유입관(106)과 유출관(107)이 결합되어 있으며 덮개(102)에는 통기관(108)이 설치된 구성으로 되어 있다.In most cases, the small manure septic tank has a cover 102 coupled to an upper portion of the upright cylinder 101 having a circular cylindrical shape, and a bottom plate 103 at the lower portion of the upright cylinder 101. Internal components such as the oxidation tank 104 and the water spray plate 105 are installed in the cylinder 100 having a combined configuration, and the inlet tube 106 and the outlet tube 107 are coupled to the upright cylinder 101. In the 102, the vent pipe 108 is provided.
또 상기와 같은 종래의 분뇨정화조에 있어서 정화조의 통체(100)는 호형의 판재를 여러개 융착 결합(결합면을 녹인 상태에서 압착 결합하는 것를 말함.)하여 직립통체(101)를 만들고 이 직립통체(101)의 상부에는 별도로 성형한 덮개(102)를 융착 결합하며 직립통체(101)의 하부에는 별도로 성형한 바닥판(103)을 융착 결합하여 제조하고 있다.In addition, in the conventional manure purification tank as described above, the tubular body 100 of the septic tank is made by fusion-bonding a plurality of arc-shaped plates (that is, press-bonding in a state where the bonding surface is melted) to make an upright cylinder 101, and the upright cylinder ( The cover 102 formed separately is fusion-bonded to the upper portion of the 101, and the bottom plate 103 formed separately is melt-bonded to the lower portion of the upright cylinder 101.
그런데 상기와 같은 방법에 의해 정화조의 통체(100)를 성형할 경우에는 여러 구성부분을 별도로 성형하여 융착 결합하는 것이므로 그 제조공정이 복잡하여 생산성을 향상시키기 곤란하였던 것이고, 또 각 구성부 사이의 연결부에 의하여 통체(100)의 내충격성이 저하되는 것이며 연결부에 발생될 수 있는 틈새를 통하여 누수현상이 발생될 우려가 있는 것이다.However, in the case of forming the tubular body 100 of the septic tank by the above-described method, since the various components are separately molded and fusion-bonded, the manufacturing process is complicated and it is difficult to improve the productivity. By this, the impact resistance of the cylinder 100 is lowered, and there is a risk of water leakage through gaps that may occur in the connecting portion.
본 고안은 상기와 같은 종래의 여러 문제점을 감안하여 고안된 것으로서, 그 목적으로 하는 것은, 직립통체와 덮개와 바닥판으로 구성된 정화조의 통체를 일체로 성형할 수 있도록 함으로서 정화조의 생산성과 내충격성을 크게 향상시킴을 물론 누수현상을 완벽하게 방지할 수 있는 정화조통체 성형용 금형을 제공하고자 하는 것에 있다.The present invention has been devised in view of the above-described various problems, and its object is to allow the body of the septic tank composed of an upright cylinder, a cover and a bottom plate to be integrally formed, thereby greatly improving the productivity and impact resistance of the septic tank. It is to provide a mold for forming a septic tank body that can be improved and of course completely prevented leakage.

It can be molded integrally.
이하 본 고안의 구체적인 일 실시예를 도면에 따라서 상세히 설명한다.Hereinafter, a specific embodiment of the present invention will be described in detail with reference to the drawings.
도 1은 본 고안에 따른 정화조통체 성형용 금형(1, 이하 '금형'이라 한다.)의 사시도, 도 2는 본 고안에 따른 금형(1)의 분해사시도를 각각 도시하고 있다.1 is a perspective view of a mold for forming a septic tank body according to the present invention (hereinafter, referred to as a 'mold'), and FIG. 2 shows an exploded perspective view of the mold 1 according to the present invention, respectively.
금형본체(2)는 정화조통체의 직립통체를 성형하기 위한 직립통체성형부(21)와, 정화조통체의 바닥판을 성형하기 위한 바닥판성형부(22)로 되어 있다.The mold main body 2 includes an upright cylindrical molding portion 21 for molding the upright cylinder of the septic tank body, and a bottom plate molding portion 22 for molding the bottom plate of the septic tank body.
상기 직립통체성형부(21)는 중공(中空)의 통(筒) 형상으로 되어 있음과 함께 상단부 가장자리 둘레에는 외측으로 돌출되게 결합판부(21a)가 형성되어 있고 또 가로 세로방향의 일정 간격마다에는 보강대성형부(21b)가 형성되어 있다.The upright cylindrical molding portion 21 has a hollow cylindrical shape, and a coupling plate portion 21a is formed around the edge of the upper end so as to protrude outwards. The reinforcement stand molding part 21b is formed.
상기 바닥판성형부(22)는 돔(Dome) 형상과 대칭되는 형상으로 되어 있음과 함께 소정의 간격마다에는 보강대성형부(22a)가 형성된 구성으로 되어 상기 직립통체성형부(21)의 하부에 직립통체성형부(21)와 일체로 형성되어 있다.The bottom plate forming portion 22 has a shape that is symmetrical with a dome shape and a reinforcing bar forming portion 22a is formed at predetermined intervals, so that the bottom plate forming portion 22 is disposed below the upright cylindrical forming portion 21. It is formed integrally with the upright cylindrical molding part 21.
금형덮개(3)는 정화조통체의 덮개를 성형하기 부분으로서 돔 형상으로 되어 있음과 함께 중앙에는 원형의 공간부(31)가 형성되어 있고 가장자리 둘레에는 외측으로 돌출되게 결합판부(32)가 형성되어 있다. 그리고 소정의 간격마다에는 보강대성형부(33)가 형성되어 있다.The mold cover 3 has a dome shape as a part for forming a cover of the septic tank body, and a circular space portion 31 is formed at the center thereof, and a joining plate portion 32 is formed to protrude outwardly around the edge. have. And the reinforcement stand forming part 33 is formed in every predetermined space | interval.
금형본체(2)와 금형덮개(3)에 있어서 보강대성형부(21b,22a,33)는 정화조통체의 외측으로 돌출되게 ' ?' 단면형의 보강대를 형성하기 위한 것으로서 위치에 따라 일체로 형성시키거나 또는 별도로 제작한 것을 용접에 의한 방법으로 결합할 수 있다.In the mold main body 2 and the mold cover 3, the reinforcing bar forming parts 21b, 22a, and 33 protrude outward of the septic tank body. It is for forming a cross-sectional reinforcement stand, which may be integrally formed according to the position, or may be separately manufactured and welded together.
상기와 같은 금형본체(2)와 금형덮개(3)는 결합판부(21a,32)를 결합볼트(4)와 너트(5)로 체결하는 것에 의해 결합되어 있다. 여기서 결합볼트(4)와 너트(5)는 클램프 등으로 대체할 수도 있다.The mold body 2 and the mold cover 3 as described above are coupled by fastening the coupling plate portions 21a and 32 with the coupling bolt 4 and the nut 5. Here, the coupling bolt 4 and the nut 5 may be replaced with a clamp or the like.
상기와 같은 본 고안의 금형(1)을 이용하여 정화조의 통체를 성형하는 과정은 다음과 같다.The process of molding the cylinder of the septic tank using the mold 1 of the present invention as described above is as follows.
본 고안의 금형(1)을 이용하여 정화조의 통체를 성형할 때에는 먼저 도 3에 도시된 바와 같이 금형(1)의 길이방향을 수평으로 하여 별도의 회전 승강장치(도시하지 않음)에 장착한다.When molding the cylinder of a septic tank using the metal mold | die 1 of this invention, as shown in FIG. 3, the longitudinal direction of the metal mold 1 is mounted horizontally, and it mounts in a separate rotary lifting apparatus (not shown).
금형(1)의 설치작업이 완료된면 금형덮개(3)의 공간부(31)를 통하여 금형(1)의 내부에 폴리에틸렌파우더를 투입한 후 금형(1)의 하부에서 금형(1)에 열을 가함과 함께 금형(1)을 지지하고 있는 회전 승강장치를 작동시켜 금형(1)을 회전시키면서 금형(1)의 길이방향 양 선단부를 상하로 소정의 각도만큼(적당하게는 상하 45°) 반복하여 승강시킨다.After the installation of the mold 1 is completed, the polyethylene powder is introduced into the mold 1 through the space 31 of the mold cover 3, and then heat is applied to the mold 1 at the bottom of the mold 1. In addition, while operating the rotary lifting device supporting the mold 1 to rotate the mold 1, the longitudinal ends of the mold 1 are repeatedly lifted up and down by a predetermined angle (45 ° upward and downward). Let's do it.
상기와 같이 금형(1)을 회전 승강시키면 금형(1) 내에 투입된 폴리에틸렌파우더는 원심력에 의해 금형(1)의 내면 전체에 고르게 확산되면서 열에 의해 금형(1)의 내면에 용융되어 밀착되고 이러한 과정을 일정시간동안 계속하면 용융된 폴리에틸렌수지는 금형(1)의 내면 형상과 동일한 형상을 갖고 일정한 두께를 갖는 형상으로 성형된다.As described above, when the mold 1 is rotated up and down, the polyethylene powder injected into the mold 1 is uniformly diffused through the entire inner surface of the mold 1 by centrifugal force, and is melted and adhered to the inner surface of the mold 1 by heat. After a certain period of time, the molten polyethylene resin is molded into a shape having the same shape as the inner surface of the mold 1 and having a constant thickness.
금형(1) 내에서 폴리에틸렌수지가 일정한 형상으로 성형되면 금형(1)의 승강작동은 정지시키고 금형(1)의 길이방향을 수평으로 한 상태에서 일정시간동안 금형(1)을 회전시키면 금형(1) 내의 폴리에텔렌수지는 형태의 변화없이 냉각되어 정형화되며 이러한 상태가 되면 승강 회전장치의 작동을 중지시킨다.When the polyethylene resin is molded to a certain shape in the mold 1, the lifting operation of the mold 1 is stopped and the mold 1 is rotated for a predetermined time while the length direction of the mold 1 is horizontal. The polystyrene resin in) is cooled and shaped without change of shape, and when it is in this state, the lifting and rotating device is stopped.
이후 결합볼트(4)와 너트(5)를 분리하고 금형덮개(3)를 금형본체(2)에서 분리한 후 성형된 금형본체(2) 내의 폴리에틸렌수지체를 금형본체(2)의 축방향으로 당겨 탈형하면 직립통체(101)와 바닥판(103)과 덮개(102)가 일체로 되고 또 직립통체(101)와 바닥판(103)과 덮개(102)에 보강대(104)가 일체로 형성된 정화조통체(100)를 얻을 수 있다. 여기서 금형본체(2)로 부터 성형된 정화조통체(100)를 탈형함에 있어서는 직립통체(101)에 가로방향으로 형성된 보강대(104)가 직립통체성형부(21)의 가로방향 보강대성형부(21b)에 걸려 탈형이 곤란할 것이라 우려할 수 있으나 금형(1) 내에서 폴리에틸렌수지체가 경화하는 과정에서는 약 5% 정도의 수축이 발생함으로 탈형에는 어떠한 문제도 발생되지 않는다.Thereafter, the coupling bolt 4 and the nut 5 are separated, and the mold cover 3 is separated from the mold body 2, and then the polyethylene resin body in the molded mold body 2 is moved in the axial direction of the mold body 2. When the mold is pulled out, the upright cylinder 101, the bottom plate 103, and the cover 102 are integrally formed, and the septic tank 104 is integrally formed with the upright cylinder 101, the bottom plate 103, and the cover 102. The cylinder 100 can be obtained. Here, when demolding the septic tank body 100 formed from the mold body 2, the reinforcing bar 104 formed in the upright cylinder 101 in the transverse direction is a transverse reinforcing bar molding part 21b of the upright cylindrical molding part 21. It may be feared that the mold would be difficult to be demolded, but the curing of the polyethylene resin in the mold 1 would result in about 5% shrinkage, which would not cause any problems in the mold release.
본 고안에 따른 정화조통체 성형용 금형은, 정화조통체의 직립통체와 바닥판을 일체로 성형하기 위한 금형본체에 정화조통체의 덮개를 성형하기 위한 금형덮개를 결합 및 분리 가능하게 결합한 것이다.The mold for forming a septic tank body according to the present invention is a mold body for molding the upright cylinder and the bottom plate of the septic tank body integrally so that the mold cover for molding the lid of the septic tank body can be combined and detachably combined.
따라서 상기와 같은 본 고안의 정화조통체 성형용 금형을 이용하여 정화조통체를 성형할 경우에는 직립통체와 바닥판과 덮개가 일체로 된 정화조통체를 얻을 수 있으므로 정화조통체의 생산성과 내충격성을 크게 향상시킬 수 있고 또 정화조통체의 누수현상을 완벽하게 방지할 수 있는 것이다.Therefore, in the case of forming the septic tank body by using the mold for forming the septic tank body of the present invention as described above, it is possible to obtain a septic tank body in which the upright cylinder, the bottom plate and the cover are integrated, thereby greatly improving the productivity and impact resistance of the septic tank body.
