Description
본 발명은 양식장용 부자 제조방법에 관한 것으로서, 더욱 상세하게는 응축수관을 통해 발포폴리프로필렌을 투입하여 부자를 제조함으로써 부자의 제조공정의 단순화를 유도할 수 있어 생산단가를 절감시키고 작업성이 용이하도록 한 양식장용 부자 제조방법에 관한 것이다.The present invention relates to a method for producing rich for aquaculture farms, and more specifically, by introducing expanded polypropylene through a condensate pipe to produce rich, it is possible to induce a simplification of the manufacturing process of the rich to reduce production costs and ease of operation. The present invention relates to a method for manufacturing rich fish for farming.
일반적으로 해양에서 그물을 이용하여 어류를 가두어 양식하는 가두리 및 바다 양식장에는 프레임이 사각 형태로 연결되고, 상기 사각 형태로 연결된 프레임의 하부에는 추에 의해 하부가 수면하부에 위치되도록 설치된 가두리 망이 연결되며, 가두리 망이 하부에 연결된 프레임의 내부에는 상기 프레임이 수면하부로 가라않는 것을 방지하는 부자(浮子)가 설치되어 있다.In general, a frame is connected to a cage and aquaculture farm where fish are trapped using a net in the ocean, and a cage is connected to a lower portion of the frame connected to the square form so that the lower portion is positioned under the water surface by a weight. The inside of the frame connected to the lower portion of the cage is provided with a rich (하는 子) to prevent the frame does not go to the bottom of the water surface.
이러한 부자는, 프레임이 수면하부로 가라않지 않도록 하는 것으로, 종래의 경우 썩지도 않고 재활용이 불가능한 스티로폼으로 제작되기 때문에 예를 들어 부자가 높은 파도 등에 의해 파손되면 스티로폼 조각들이 해변에 쌓이거나 해안에 부유하게 됨은 물론, 부자를 폐기처분시 자연환경을 파손시키게 되는 문제점이 있었다.These rich people ensure that the frame does not go to the bottom of the surface. In the conventional case, since the styrofoam is made of non-rotable and non-recyclable styrofoam, for example, if the rich pieces are broken by high waves, the pieces of styrofoam are piled up on the beach or floating on the shore. Of course, there was a problem that will destroy the natural environment when the rich disposal.
이에 따라, 근자 들어서는 프레임에 부력을 주는 부자를 UV코팅된 고밀도(High Density) 폴리에틸렌(Polyethylene)이나 고강도 고무파이프 및 우레탄, FRP 등으로 제작 하여 스티로폼으로 제작된 부자보다 강도를 향상시키고, 상기 부자를 폐기처분시 재활용이 이루어지도록 하고 있다.Accordingly, the rich that gives the buoyancy to the frame is made of UV-coated high density polyethylene (Polyethylene), high-strength rubber pipe and urethane, FRP, etc. to improve the strength than the rich made of styrofoam, the rich Recycling is allowed at disposal.
또한, 재활용이 가능한 친환경소재인 발포폴리프로필렌(EPP)을 이용하여 부자를 제조하고 있다.In addition, it is manufacturing rich by using expanded polypropylene (EPP), which is an eco-friendly material that can be recycled.
그러나, 발포폴리프로필렌을 이용하여 부자를 제조하는 공정에서 물리적 발포한 상태에서 고온고압의 증기를 이용하여 결합하게 되는데, 제품의 두께가 200mm 이상일 때 표면의 경우 올바르게 성형이 이루어지나 내부의 경우 증기압이 도달하지 않아 결합되지 않은 상태가 되므로 외력에 의한 내구성이 떨어지는 문제점이 있다.However, in the process of manufacturing rich by using expanded polypropylene, it is bonded by using a high temperature and high pressure steam in the physically foamed state. When the thickness of the product is 200mm or more, the surface is formed correctly, but the vapor pressure is internal. There is a problem that durability is not due to external force because it does not reach the state that is not coupled.
종래 기술을 살펴보면, 등록특허 10-1065116호인 양식장용 부자 및 그 제조방법이 안출된 바 있으며 이는, EVA 수지 60∼80중량％와, NBR 20∼40중량％가 한 번의 발포로 최종적인 부자의 형태를 가진 본체가 통째로 형성된 양식장용 부자와, EVA 수지 60∼80중량％와, NBR 20∼40중량％를 혼합하여 형틀에 넣어 최종적인 부자의 형태를 가진 예비 성형물을 만드는 제1단계, 형틀을 가온하여 130∼170℃가 되게 하고, 20∼40분 동안 발포하는 제2단계를 포함하여 구성된 양식장용 부자의 제조방법이 제공된다.Looking at the prior art, the rich for farming and the manufacturing method has been devised Patent No. 10-1065116, which is 60 to 80% by weight of EVA resin, 20 to 40% by weight of NBR in one foam of the final rich form The first step of preparing a preform having a final rich form by mixing the rich body for farming with a main body having a shape of the aquaculture, 60 to 80% by weight of EVA resin and 20 to 40% by weight of NBR, and heating the mold It is made to 130 ~ 170 ℃, and a method for producing a rich farm for farming comprising a second step of foaming for 20 to 40 minutes.
다른 예로서, 공개특허 10-1995-0028606호인 이중구조부자와 그의 제조방법이 안출된 바 있으며, 이는 폴리스티렌 발포체의 부자 표면을 폴리에틸렌과 폴리스티렌의 공중합 발포체 입자, 폴리프로필렌 발포체 입자 또는 폴리에틸렌 발포체 입자로 충전한 후 성형 코팅하여 제조하여 내마찰성과 내충격성이 우수하도록 하고 있다.As another example, there has been devised a double-structured rich person and a method for preparing the same, which is disclosed in Korean Patent No. It is then manufactured by molding coating to have excellent friction resistance and impact resistance.
그러나, 이러한 종래 기술에 의해 부자를 제조하는 과정에서 공정상의 복잡함에 의해 생산단가가 크게 증대되는 문제점이 있다.However, there is a problem that the production cost is greatly increased due to the complexity of the process in the process of manufacturing rich by this conventional technology.
더욱이, 증기압이 제대로 이루어지지 않거나 또는 스팀의 압력 조절을 제대로 조절하지 못함에 따라 불량률이 발생되는 문제점이 있다.Moreover, there is a problem that the defective rate is generated due to poor steam pressure or poor pressure control of the steam.

이하에서는, 본 발명의 실시예에 따른 양식장용 부자 제조방법을 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, a method for manufacturing rich for farming according to an embodiment of the present invention will be described in detail.
도시된 바와 같이 본 발명인 양식작용 부자 제조방법은, 제1공정(S1) 내지 제8공정(S8)으로 이루어진다.As shown in the figure, the method for producing aquaculture-rich riches comprises the first step (S1) to the eighth step (S8).
본 발명의 제1공정(S1)은, 성형하고자 하는 부자의 외형과 동일한 형상을 갖고 내부가 중공 형성된 성형틀 내부에 제1응축수관을 인입하고 제1응축수관을 통해 발포폴리프로필렌(Expanded Polypropylene, EPP) 입자를 투입한다.In the first step (S1) of the present invention, the first condensed water pipe is introduced into a molding frame having the same shape as the outer shape of the rich to be molded and the hollow is formed, and the expanded polypropylene is expanded through the first condensed water pipe. EPP) particles.
이 때 발포폴리프로필렌(Expanded Polypropylene, EPP)을 물리적인 장치에 의해 성형틀의 내부로 투입한다.At this time, expanded polypropylene (EPP) is introduced into the mold by a physical device.
상기 제2공정(S2)은, 상기 제1응축수관을 통해 발포폴리프로필렌(Expanded Polypropylene, EPP)입자가 투입된 성형틀 내부에 제2응축수관 및 스팀투입관을 삽입한다.In the second step (S2), the second condensed water pipe and the steam injection pipe are inserted into a molding mold into which expanded polypropylene (EPP) particles are introduced through the first condensed water pipe.
이 때, 성형틀에는 응축수관들과 스팀투입관이 투입될 수 있는 투입구들이 형성되는 것이 당연하며 투입구들과 투입된 응축수관들 및 스팀투입관들은 서로 밀착 밀폐됨으로써 응축수관 및 스팀이 새어나오는 것을 방지한다.At this time, it is natural that the mold is formed with inlets through which the condensate pipes and the steam inlet pipes can be formed, and the inlets, the condensate pipes and the steam inlet pipes are tightly sealed together to prevent leakage of the condensate pipes and steam. do.
상기 제3공정(S3)은, 제2공정(S2)에서 성형틀 내부로 투입된 스팀투입관을 통해 압력밸브수치 5kgf/㎠ 까지 스팀을 성형틀 내부에 1차 공급한다.The third step (S3), the first supply of steam to the inside of the mold to the pressure valve value 5kgf / ㎠ through the steam injection pipe introduced into the mold in the second step (S2).
이 때, 스팀투입관의 투입부측에 압력게이지를 설치하여 압력이 5kg 이상이면 자동으로 스팀투입관이 잠겨져 스팀의 공급을 차단하고 압력이 5kg 이하이면 자동으로 개방되어 스팀이 공급되도록 함으로써 시간에 관계없이 압력에 의해 항상 일정한 압력이 이루어지도록 한다.At this time, the pressure gauge is installed on the inlet side of the steam inlet tube so that if the pressure is 5 kg or more, the steam inlet tube is automatically locked to shut off the supply of steam, and if the pressure is 5 kg or less, it is automatically opened to allow steam to be supplied. Constant pressure is always achieved by means of pressure.
또한, 상기 응축수관에는 압력밸브를 설치함으로써 상기 제4공정(S4)에 의해 압력밸브를 열어 1차 응축수를 방출하도록 한다.In addition, by installing a pressure valve in the condensate pipe to open the pressure valve by the fourth step (S4) to discharge the primary condensate.
상기 제5공정(S5)은, 1차 응축수를 방출한 다음, 1차 응축수가 방출된 성형틀 내부에 스팀투입관을 통해 압력밸브수치 5kgf/㎠ 까지 스팀을 2차 공급한다.In the fifth step (S5), after discharging the first condensate, the second supply of steam to the pressure valve value of 5kgf / ㎠ through the steam injection pipe inside the molding mold in which the primary condensate is discharged.
이때에도 역시 스팀투입관의 투입부측에 설치된 압력게이지를 통해 압력이 5kg 이상이면 자동으로 스팀투입관이 잠겨져 스팀의 공급을 차단하고 압력이 5kg 이하이면 자동으로 개방되어 스팀이 공급되도록 함으로써 시간에 관계없이 압력에 의해 항상 일정한 압력이 이루어지도록 한다.In this case, too, the pressure gauge installed on the input side of the steam inlet pipe automatically locks the steam inlet pipe when the pressure is 5 kg or more, and shuts off the supply of steam. Constant pressure is always achieved by means of pressure.
상기 제6공정(S6)은, 상기 응축수관에 설치된 압력밸브를 열어 2차 응축수를 방출하는 공정이다.The sixth step (S6) is a step of discharging secondary condensate by opening a pressure valve provided in the condensate pipe.
이와 같이 발포폴리프로필렌(Expanded Polypropylene, EPP)입자가 투입된 성형틀 내부를 1차 스팀을 공급하여 발포폴리프로필렌(Expanded Polypropylene, EPP)입자가 발포되도록 하고 응축수를 배출한 다음, 다시 2차 스팀을 공급하여 발포폴리프로필렌(Expanded Polypropylene, EPP)입자의 발포가 이루어지도록 하며 또한 응축수를 배출하기 때문에 발포폴리프로필렌(Expanded Polypropylene, EPP)입자에 의한 부자의 발포성형이 용이하게 이루어진다.In this way, the primary steam is supplied to the inside of the forming mold in which the expanded polypropylene (EPP) particles are injected to expand the expanded polypropylene (EPP) particles, discharge the condensate, and then supply the second steam again. Therefore, foaming of expanded polypropylene (Expanded Polypropylene, EPP) particles is carried out, and since the condensate is discharged, rich foaming is easily performed by expanded Polypropylene (Expanded Polypropylene, EPP) particles.
또한, 발포폴리프로필렌(Expanded Polypropylene, EPP)입자의 발포성형과정에서 발생되는 크랙이나 미발포된 부분이 발생되는 것을 방지할 수 있다.In addition, it is possible to prevent the occurrence of cracks or unfoamed parts generated during the expansion molding of expanded polypropylene (Expanded Polypropylene, EPP) particles.
상기와 같이 발포폴리프로필렌(Expanded Polypropylene, EPP)입자의 발포작업이 모두 진행된 후에는 제7공정(S7)에 의해 성형틀 내부로 삽입된 응축수관들 및 스팀투입관을 성형틀 내부로부터 분리한다.After the expansion of the expanded polypropylene (Expanded Polypropylene, EPP) particles as described above, the condensed water pipes and the steam injection pipe inserted into the mold by the seventh process (S7) is separated from the mold.
또한, 제7공정에 의해 응축수관들과 스팀투입관이 분리된 성형틀의 투입구를 제8공정(S8)에 의해 밀봉함으로써 성형틀 내부에서의 성형되는 부자를 냉각한다.In addition, by sealing the inlet of the molding mold in which the condensed water pipes and the steam inlet pipe separated by the seventh process by the eighth process (S8) to cool the rich to be molded in the mold.
상기 제8공정 이후에는 성형틀을 개방하여 성형된 부자를 취출한 후 취출된 부자를 다시 상온에서 건조한다.After the eighth step, the molded rich body is opened to take out the molded rich man, and the extracted rich man is dried again at room temperature.
