Description

합성수지 원료 배합장치{PVC Resin Mixing Device}Synthetic resin raw material mixing device {PVC Resin Mixing Device}

본 발명은 합성수지 원료 배합장치에 관한 것으로, 더욱 상세하게는 합성수지 원료, 즉 피브씨 레진과 열안정제 및 첨가물이 열풍에 의해 균일하게 배합될 수 있도록 하기 위한 합성수지 원료 배합장치에 관한 것이다.The present invention relates to a synthetic resin raw material blending device, and more particularly, to a synthetic resin raw material blending device for uniformly blending synthetic resin raw materials, ie, fib C resin, heat stabilizer and additives by hot air.

종래의 합성수지 원료 배합장치는 피브이씨(pvc) 레진과 열안정제, 탄산칼슘 등의 첨가물(이하 이들을 모두 '합성수지 원료'라 칭한다)을 함께 배합기에 넣고 고속으로 칼날을 회전시키면 합성수지 원료가 칼날과 마찰되고 온도가 상승하면서 합성수지 원료가 균일하게 혼합되는데, 이때 배합기 내부의 온도가 120~140℃ 정도 상승하게 되면 피브이씨 레진에 열안정제와 첨가물이 흡착되면서 배합이 이루어지게 된다.Conventional synthetic resin raw material mixing device is a combination of the PVC resin, heat stabilizer, calcium carbonate and other additives (hereinafter referred to as 'synthetic resin raw material') in the blender at high speed to rotate the blade and the synthetic resin raw material As the friction and the temperature increase, the synthetic resin raw material is uniformly mixed. At this time, when the temperature inside the blender rises to about 120 to 140 ° C., the heat stabilizer and the additive are adsorbed onto the fibC resin to mix.

이처럼 열안정제와 첨가물이 흡착되어 배합된 피브이씨 레진은 온도가 너무 높을 경우 경화될 가능성이 있어 이를 냉각 블랜더로 이송하여 냉각시킨 후 압출기로 이송하여 제품을 압출·성형하게 된다.As the heat stabilizer and additives are adsorbed and blended, the fibrous resin may be cured when the temperature is too high. The fibrous resin is then transferred to a cooling blender, cooled, and then transferred to an extruder to extrude and mold a product.

따라서 상기와 같이 합성수지 원료의 균일한 배합과 흡착을 위해 실용신안등록 제186141호와 같이 배합기의 내부에 건조장치를 일체로 설치하여 배합 재료를 건조시키면서 배합함으로써 별도의 건조공정을 거치지 않고 보다 간편하게 재료를 배합할 수 있도록 하는 수직형 자동배합기가 안출된 바 있으나, 이는 배합통(호퍼)의 내부에 설치한 스크류의 외부에 재료 상승 유도관을 설치하고 당해 재료 상승 유도관의 상부로 노출된 스크류에 비산익편을 부착하여 투입구로 투입된 배합재료를 재료 상승 유도관에 의해 스크류의 최상부까지 이송시킴과 동시에 비산익편에 의거 스크류의 외부로 비산 시킬 수 있게 한 구조여서 배합재료에 수분이 혼합되어 있거나 재료를 세척한 후 배합해야 되는 경우에는 배합기에 재료를 투입하기 전에 먼저 건조기에서 건조시킨 후 작업을 실시해야 됨에 따라 작업이 번거롭고 작업시간이 오래 걸리는 등 단점을 갖는 것이다.Therefore, in order to uniformly mix and adsorb synthetic resin raw materials as described above, as in Korean Utility Model Registration No. 186141, a drying device is integrally installed inside the blender and blended while drying the blending material, thereby simplifying the material without a separate drying process. Although a vertical automatic mixer has been devised, the material raising induction pipe is installed on the outside of the screw installed inside the mixing vessel (hopper) and the screw exposed to the upper portion of the material rising induction pipe is installed. It is designed to transfer the compounding material introduced through the inlet port to the top of the screw by the material induction pipe and to scatter the material outside the screw based on the flying wing piece. If it is necessary to mix after washing, first in the dryer As was crude have to carry out working to have a drawback such as the operation cumbersome, time-consuming work.

상기와 같은 단점을 해결하기 위해 실용신안등록출원 제20-2000-31000호는 스크류의 외부에 재료 상승 유도관을 설치된 재료 배합통의 내부에 다수개의 급기공이 뚫린 열풍관을 다수개 주립 설치하여 배합통의 외부에 설치한 송풍기에 의해 히터열을 열풍관으로 송풍하므로서 재료 상승 유도관의 상부를 통해 낙하 비산되는 재료를 배합과 동시에 건조시킬 수 있게 함으로써 별도의 건조공정이 없이 배합되는 재료를 건조시킬 수 있도록 구성된 구조를 갖는다.In order to solve the above drawbacks, Utility Model Registration Application No. 20-2000-31000 has installed a plurality of state hot air pipes in which a plurality of air supply holes are perforated inside a material mixing vessel in which a material raising induction pipe is installed outside the screw. A blower installed outside of the mixing vessel blows the heat of the heater to the hot air pipe, allowing the material to be dropped and scattered through the upper portion of the material induction pipe to be dried at the same time as the mixing, thereby drying the blended material without a separate drying process. It has a structure configured to be able to.

따라서 종래의 합성수지 원료 배합장치는 배합을 위해 배합통(호퍼)의 내부로 유입된 합성수지원료가 스크류에 의해 상부까지 이송된 다음 비산익편에 의해 살포되어 비산되면서 교반, 건조되는 구조를 갖는 것이어서 스크류와 비산익편과 같은 별도의 장치를 배합통 내부에 설치하여야 하며, 따라서 배합통의 내부 체적이 줄어들게 되어 배합하여야 할 합성수지원료의 양은 줄어들 수밖에 없는 단점을 갖는 것이며, 또 다수개의 열풍관이 배합통 상부에 수직으로 형성되어 열풍이 상부에서 하부로 분사되는 구조를 갖는 것이어서 자연법칙, 즉 열풍은 공기보다 가벼워 아래에서 위로 상승되는 법칙에 반대로 작용하게 되므로 열풍의 건조효율이 현저히 떨어지는 단점을 갖는 것이다.Therefore, the conventional synthetic resin raw material mixing device has a structure in which the synthetic resin support material introduced into the mixing vessel (hopper) for mixing is transferred to the upper portion by the screw, then sprayed and scattered by the fly wing, and then stirred and dried. A separate device, such as fly wing, should be installed inside the mixing vessel, and therefore, the internal volume of the mixing vessel is reduced, so that the amount of synthetic water support to be mixed has to be reduced, and a plurality of hot air pipes are placed on the upper portion of the mixing vessel. It is formed vertically and has a structure in which hot air is injected from the top to the bottom, so that the natural law, that is, hot air is lighter than air and thus acts against the law of rising from the bottom to the bottom, so that the drying efficiency of hot air is significantly lowered.

이를 위해 본 발명은 합성수지 원료, 즉 피브씨 레진과 열안정제 및 첨가물이 열풍에 의해 균일하게 배합될 수 있도록 하되 열풍이 호퍼의 하부로 부터 유입되어 자연스럽게 상승하면서 호퍼 내부에 충진된 합성수지 원료 들을 상하로 순환시킴으로써 균일하게 배합될 수 있도록 하고, 동시에 건조가 가능하도록 하였다.To this end, the present invention allows the synthetic resin raw materials, that is, the fib C resin and the heat stabilizer and the additives to be uniformly mixed by the hot air, but the hot air flows from the lower portion of the hopper and naturally rises, thereby filling the synthetic raw material filled in the hopper up and down. By circulating, it was possible to mix evenly and at the same time allow drying.

또한 본 발명은 열풍의 공급을 위해 콤프레셔를 이용하되 콤프레셔에서 발생하는 고온의 압축공기를 이용하여 가열탱크를 예열하도록 하고, 가열탱크에는 고압공기의 수분제거와 재가열을 위한 히터를 형성하여 고온고압의 열풍이 호퍼로 공급되도록 하였다. In addition, the present invention is to use a compressor for the supply of hot air to preheat the heating tank by using a high-temperature compressed air generated in the compressor, to form a heater for removing water and reheating the high-pressure air in the heating tank of the high temperature and high pressure Hot air was supplied to the hopper.

이처럼 본 발명은 열풍의 분사방향을 자연의 법칙에 위배되지 않는 방향으로 분사하여 균일한 교반을 통한 합성수지 원료의 탁월한 배합효과를 얻을 수 있으며, 또 합성수지 원료의 분사 및 교반을 위한 별도의 장치를 호퍼 내에 설치하지 않아도 되어 공간을 효율적으로 활용할 수 있는 효과를 갖는 것이다.      As such, the present invention can obtain an excellent mixing effect of the synthetic resin raw material through uniform agitation by spraying the spraying direction of hot air in a direction that does not violate the laws of nature. There is no need to install in the space to have the effect of efficient use of space.

또한 히터의 효율적인 배치와 콤프레셔로부터 발생하는 고온의 압축공기를 이용하여 가열탱크의 내부를 예열하도록 하고, 수분이 제거된 열풍만을 호퍼로 유입되도록 함으로써 전력손실을 최소화하여 에너지를 절약할 수 있는 매우 유용한 발명인 것이다. In addition, it is very useful to save energy by minimizing the power loss by preheating the inside of the heating tank using the efficient arrangement of the heater and the high temperature compressed air generated from the compressor and allowing only the hot air from which moisture is removed into the hopper. It is an invention.
