Description

합성수지 원료 배합장치용 고압공기분사노즐{Air nozzle for PVC resin mixing device}Air nozzle for PVC resin mixing device

본 발명은 합성수지 원료 배합장치용 고압공기분사노즐에 관한 것으로, 더욱 상세하게는 고압과 고온의 열풍을 분사하여 합성수지 원료(피브이씨 레진과 열안정제 및 첨가물)가 열풍에 의해 균일하게 배합될 수 있도록 하기 위한 합성수지 원료 배합장치용 고압공기분사노즐에 관한 것이다.The present invention relates to a high pressure air spray nozzle for a synthetic resin raw material mixing device, and more specifically, synthetic resin raw materials (FIG resin and heat stabilizer and additives) may be uniformly mixed by hot air by spraying hot air at high pressure and high temperature. The present invention relates to a high pressure air spray nozzle for a synthetic resin raw material mixing device.

종래의 합성수지 원료 배합장치는 피브이씨(pvc) 레진과 열안정제, 탄산칼슘 등의 첨가물(이하 이들을 모두 '합성수지원료'라 칭한다)을 함께 배합기에 넣고 고속으로 칼날을 회전시키면 합성수지 원료가 칼날과 마찰하고 이와 함께 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 water support material') into the blender and rotating the blade at high speed, the synthetic resin raw material and the blade As the friction and the temperature rises, the synthetic resin 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, and the mixing is performed.

상기와 같이 스크류에 비산익편을 부착하여 투입구로 투입된 배합재료를 재 료 상승 유도관에 의해 스크류의 최상부까지 이송시킴과 동시에 비산익편에 의거 스크류의 외부로 비산 시킬 수 있게 한 종래의 합성수지 원료 배합장치는 배합재료에 수분이 혼합되어 있거나 재료를 세척한 후 배합되는 경우에는 배합기에 재료를 투입하기 전에 먼저 건조기에서 건조시킨 후 작업을 실시해야 하므로 작업이 번거롭고 작업시간이 오래 걸리는 등 단점을 갖는 것이다.Conventional synthetic resin raw material mixing device that attaches the fly wing to the screw and transfers the compounding material introduced through the inlet to the top of the screw by the material raising induction pipe and at the same time scatters the outside of the screw based on the fly wing. In the case that the mixing material is mixed with water or the material is washed and then blended, it must be dried in a dryer before the material is added to the blender, and therefore the work is cumbersome and takes a long time.

상기와 같은 단점을 해결하기 위해 실용신안등록출원 제20-2000-31000호는 스크류의 외부에 재료 상승 유도관을 설치된 합성수지 재료 배합통의 내부에 다수개의 급기공이 뚫린 열풍분사관을 다수개 주립 설치하여 배합통의 외부에 설치한 송풍기에 의해 히터열을 열풍분사관으로 송풍하므로서 재료 상승 유도관의 상부를 통해 낙하 비산되는 재료를 배합과 동시에 건조시킬 수 있게 함으로써 별도의 건조공정이 없이 배합되는 재료를 건조시킬 수 있도록 구성된 합성수지 원료 배합장치가 개발된 바 있다.In order to solve the above drawbacks, Utility Model Registration Application No. 20-2000-31000 states that a plurality of hot air spray pipes are formed in which a plurality of air holes are drilled in the inside of a synthetic resin material mixing vessel in which a material raising induction pipe is installed outside the screw. The blower installed outside of the mixing tank is used to blow the heat of the heater to the hot air injector tube so that the material that is dropped and scattered through the upper portion of the material induction pipe can be mixed and dried at the same time without mixing. Synthetic resin raw material mixing device has been developed configured to dry the material.

그러나, 상기한 바와 같은 종래의 합성수지 원료 배합장치는 송풍기에 의해 발생한 고압의 공기를 히터로 데워서 열풍분사관으로 분사하는 구조를 갖는 것이긴 하나, 이때 열풍분사관은 상부를 향해 있고 입구가 개방된 구조를 갖는 것이어서 고압의 공기에 의해 위로 상승했던 미세한 합성수지 원료가 하강하면서 열풍분사관 속으로 유입되기도 하는 단점을 갖는다.However, the conventional synthetic resin raw material mixing device as described above has a structure in which the high-pressure air generated by the blower is heated by a heater and sprayed to the hot air jet pipe, but the hot air jet pipe is directed upward and the inlet is opened. Since it has a structure, the fine synthetic resin raw material, which has risen upward by the high pressure air, has a disadvantage of being introduced into the hot air spray pipe while falling.

이는 원활한 합성수지 원료의 배합을 방해할 뿐만 아니라 열풍분사관의 내부로 유입된 합성수지 원료에 의해 열풍분사관이 막히거나, 고장의 원인이 되기도 하는 단점을 갖는다.This not only prevents the smooth mixing of the synthetic resin raw material but also has the disadvantage that the hot air injection pipe is blocked by the synthetic resin raw material introduced into the hot air injection pipe, or it may cause a failure.

따라서 본 발명은 합성수지 원료가 열풍분사관에 유입될 수 없도록 열풍분사관의 입구에 열풍은 분사할 수 있으면서 합성수지 원료는 유입될 수 없도록 고압공기분사노즐이 형성되도록 한 것이다. Therefore, the present invention is to form a high-pressure air spray nozzle so that the synthetic resin raw material can not be introduced while the hot air can be injected into the inlet of the hot air injection pipe so that the synthetic resin raw material does not flow into the hot air injection pipe.

이처럼 본 발명은 합성수지 원료의 배합을 위한 고압 고온의 열풍을 분사할 수 있으면서도 합성수지 원료가 열풍분사관으로 유입되는 것을 이중으로 차단할 수 있도록 하여 열풍분사관이 막히는 것을 방지하고, 고장의 원인이 최소화할 수 있는 매우 유용한 발명인 것이다. As described above, the present invention is capable of injecting a high pressure and high temperature hot air for the compounding of the synthetic resin raw material, thereby preventing the synthetic resin raw material from being introduced into the hot air spray pipe twice, thereby preventing the hot air spray pipe from being blocked and minimizing the cause of the failure. It is a very useful invention that can be.

이하 첨부된 도면에 의해 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명 합성수지 원료 배합장치용 고압공기분사노즐(100)은 합성수지 원료를 배합하기 위한 배합통(A)의 바닥에 다수개 형성되어 지며, 그 구조는 다음과 같 다. 즉 배합통(A)에 나사결합되며 하부에 공기유입구(111)와 측면에 공기배출구(112)를 구비하는 밸브 하우징(110)과, 상기 밸브 하우징(110)의 공기유입구(111)를 차단하기 위한 밸브(120)와, 상기 밸브(120)를 눌러주기 위한 밸브 누름구(130)와, 상기 밸브 누름구(130)의 상단에 형성된 밸브 로드(131)와, 상기 밸브 누름구(130)에 탄성을 부여하기 위한 스프링(140)과, 상기 스프링(140)이 하방으로 탄성이 작용하도록 하고 밸브 로드(131)의 승·하강 구동시 이를 지지할 수 있도록 하는 결합부재(150)가 밸브 하우징(110)에 나사 결합되도록 구성되어 진다.The high pressure air spray nozzle 100 for the synthetic resin raw material mixing device of the present invention is formed in the bottom of the mixing barrel (A) for compounding the synthetic resin raw material, the structure is as follows. That is, the valve housing 110 is screwed to the mixing cylinder (A) and provided with an air inlet 111 at the bottom and an air outlet 112 at the side, and to block the air inlet 111 of the valve housing 110. Valve 120, a valve presser 130 for pressing the valve 120, a valve rod 131 formed at an upper end of the valve presser 130, and the valve presser 130. A spring 140 for imparting elasticity and a coupling member 150 for allowing the spring 140 to elastically act downward and support the spring when the valve rod 131 is driven up and down are provided in the valve housing ( It is configured to be screwed to 110).

상기 밸브(130)는 구(球) 형상으로 이루어지며, 따라서 공기유입구(111)의 상단과 밸브 누름구(130)의 하단의 형상도 밀폐와 지지를 용이하게 하기 위하여 반구(半球)의 형상을 갖도록 함이 바람직하다.The valve 130 is formed in a spherical shape, and thus the shape of the upper end of the air inlet 111 and the lower end of the valve presser 130 also has a hemispherical shape to facilitate sealing and support. It is preferable to have.

또한 상기 밸브 로드(131)는 결합부재(150)의 중앙에 천공된 로드 삽입공(152)을 통해 결합부재(150)의 상단으로 노출되도록 구성할 수도 있는데, 이는 상기 로드 삽입공(152)을 통해 합성수지재료 분말이 유입되지 못하도록 로드 삽입공(152) 상단을 깔때기 형태의 오목홈(153)을 형성하고, 상기 오목홈(153)은 밸브 로드(131)에 삽입되어 스프링(140)에 의해 견인력이 작용하는 원추형 마개(160)에 의해 차단되도록 하기 위해 필요한 구성이다.In addition, the valve rod 131 may be configured to be exposed to the upper end of the coupling member 150 through the rod insertion hole 152 bored in the center of the coupling member 150, which is the rod insertion hole 152 A concave groove 153 having a funnel shape is formed at the top of the rod insertion hole 152 so that the synthetic resin material powder does not flow therethrough, and the concave groove 153 is inserted into the valve rod 131 to be pulled by the spring 140. It is a configuration necessary to be blocked by the acting conical stopper 160.

이때 상기 원추형 마개(160)는 밸브 로드(131)의 끝단에 형성된 걸고리 체결공(132)에 걸려있는 걸고리(170)에 의해서 밸브 로드(131)로부터 이탈되지 않게 된다.In this case, the conical stopper 160 is not separated from the valve rod 131 by the hook 170 hanging on the hook fastening hole 132 formed at the end of the valve rod 131.

이처럼 본 발명 합성수지 원료 배합장치용 고압공기분사노즐(100)은 공기유 입구(111)로부터 스프링(140)의 탄발력을 상회 하는 고온고압의 열풍이 유입될 경우 밸브(120)와 상기 밸브(120)를 눌러주기 위한 밸브 누름구(130)가 상승하게 되고, 그 결과 공기배출구(112)를 통해 고온고압의 열풍이 분사되면서 배합통(A)의 합성수지 원료를 와류 시키게 되고, 이로 인해 상기 합성수지 원료들이 균일하게 혼합되어 진다.As described above, the high pressure air injection nozzle 100 for the synthetic resin raw material mixing device has a valve 120 and the valve 120 when a high temperature and high pressure hot air is introduced from the air oil inlet 111, which exceeds the elasticity of the spring 140. The valve presser 130 for pressing) rises, and as a result, hot air of high temperature and high pressure is injected through the air outlet 112 to vortex the synthetic resin raw material of the mixing container A, thereby the synthetic resin raw material Are mixed evenly.

반대로 공기유입구(111)로부터 유입되는 고온고압의 열풍이 스프링(140)의 탄발력보다 약할 경우 스프링(140)의 탄발력에 의해 밸브 누름구(130)는 하강하게 되고, 상기 밸브 누름구(130)는 밸브(120)를 눌러주게 되어 공기유입구(111)를 차단하게 된다. 이때 상기 밸브 누름구(130)는 하강함과 동시에 밸브 로드(131)를 잡아당기게 되고 또 상기 밸브 로드(131)는 원추형 마개(160)를 잡아당기게 되어 로드 삽입공(152)이 차단되어 진다. 이로 인해 로드 삽입공(152)을 통해 합성수지 원료가 유입되는 것을 차단할 수 있게 된다.On the contrary, when the hot air of the high temperature and high pressure introduced from the air inlet 111 is weaker than the spring force of the spring 140, the valve press hole 130 is lowered by the spring force of the spring 140. ) Presses the valve 120 to block the air inlet 111. At this time, the valve pusher 130 is lowered and at the same time pulls the valve rod 131, and the valve rod 131 is pulled by the conical stopper 160 is blocked the rod insertion hole 152. As a result, the synthetic resin raw material can be blocked from being introduced through the rod insertion hole 152.
