Description

발포소재 믹싱헤드{Mixing head of foaming material}[0001] Mixing head of foaming material [0002]

본 발명은 발포소재 믹싱헤드에 관한 것이다.The present invention relates to a foam material mixing head.

일반적으로 폴리우레탄 같은 발포성 수지는 아이소시아네이트(Isocianat)와 폴리올(Polyol)과의 반응에 의해 생성된다. 믹싱헤드는 이러한 발포소재들을 교반시키고 분사한다. 이를 위해, 믹싱헤드는 발포소재가 교반되는 공간을 형성하는 하우징과, 하우징 내부에서 회전하여 발포소재를 교반하는 임펠러를 갖는다.In general, expandable resins such as polyurethane are produced by the reaction of an isocyanate with a polyol. The mixing head stirs and ejects these foam materials. To this end, the mixing head has a housing which forms a space in which the foam material is stirred, and an impeller which rotates inside the housing to stir the foam material.

믹싱헤드의 교반 정도는 제조되는 폴리우레탄의 품질에 중요한 영향을 미친다. 즉, 발포소재들의 교반을 확실하게 할수록, 생성되는 풀리우레탄의 품질이 향상되는 것이다.The degree of agitation of the mixing head has an important influence on the quality of the polyurethane produced. That is, the more agitated the foaming materials are, the better the quality of the resulting pulley urethane is.

그러나 종래의 믹싱헤드는 교반 정도가 만족스럽지 못하다. 그리고 불필요하게 부피가 커서 유지보수가 불편하고, 그만큼 모터의 구동력도 강력한 것을 사용해야 했기 때문에 장치의 비용을 불필요하게 증대하는 문제점이 있었다.However, the mixing head of the conventional mixing head is not satisfactory. In addition, since the motor is unnecessarily bulky, maintenance is inconvenient, and the driving force of the motor is also required to be high, there is a problem that the cost of the apparatus is unnecessarily increased.

본 발명의 목적은 콤팩트한 구조로써 발포소재의 교반효과를 극대화하는 믹싱헤드를 제공하는 것이다.An object of the present invention is to provide a mixing head that maximizes the stirring effect of a foamed material with a compact structure.

본 발명에 따른 발포소재 믹싱헤드는 축선을 따라 연장된 관상의 원통부와, 상기 원통부의 일단부에 발포소재를 공급하는 적어도 하나의 공급관과 연결되는 공급관 연결부와, 상기 원통부의 타단부에 탈착 가능하게 결합되어 상기 발포소재의 혼합액이 토출되는 토출노즐을 갖는 하우징과, 상기 하우징 내부에 동심적으로 수용되는 임펠러 본체와, 상기 임펠러 본체로부터 원주방향 및 축선방향을 따라 분산 배치되는 복수의 돌출날개를 갖는 임펠러와, 상기 원통부의 내벽으로부터 상기 돌출날개들의 축선방향 이격 틈새로 돌출되도록 배치되는 교반돌기와, 상기 임펠러와 축선 결합하여 상기 임펠러를 회전시키는 모터를 포함한다.The foamed material mixing head according to the present invention comprises a cylindrical tubular part extending along an axis, a supply pipe connecting part connected to at least one supply pipe for supplying a foamed material to one end of the cylindrical part, And a plurality of protruding blades dispersedly disposed in the circumferential direction and the axial direction from the impeller body, and a plurality of protruding blades And a motor for rotating the impeller in axial engagement with the impeller. The impeller of the present invention comprises: an impeller having an impeller for rotating the impeller; a stirring protrusion disposed so as to protrude from an inner wall of the cylindrical portion to a clearance in an axial direction of the protruding blades;

여기서, 상기 하우징은 측벽에 적어도 하나의 관통공이 형성되며, 상기 교반돌기는 상기 하우징의 외측에서 상기 관통공을 통해 내부로 탈착 가능하게 삽입되는 것이 믹싱헤드의 보수에 유리하다.In this case, at least one through-hole is formed in the side wall of the housing, and the stirring protrusion is detachably inserted from the outside of the housing through the through-hole to the maintenance of the mixing head.

그리고 상기 돌출날개들 중 적어도 하나는 상기 임펠러의 회전 시 상기 발포소재가 상기 토출노즐 측으로 이동되도록 하는 경사면을 갖는 것이 교반에 있어서 유리하다.And at least one of the protruding blades has an inclined surface in which the foamed material is moved toward the discharge nozzle side when the impeller is rotated.

또한, 상기 돌출날개는 상기 임펠러 본체의 축선방향에 대해 가로방향을 따라 연장되는 수평판면을 가지고, 상기 경사면은 상기 수평판면의 대향측에 배치되는 것이 콤팩트한 구조를 가지는데 있어서 유리하고, 또한 하향흐름을 강제하고 수평회전유동이 유발되기 때문에 상호 작용되어 난류를 발생시켜 교반효과를 극대화하는 효과를 발휘한다.Further, it is advantageous that the protruding vanes have a horizontal plate surface extending in the transverse direction with respect to the axial direction of the impeller body, and the inclined surfaces are disposed on the opposite sides of the horizontal plate surface in order to have a compact structure, Since the flow is forced and the horizontal rotating flow is induced, the turbulent flow is generated to maximize the stirring effect.

여기서, 상기 교반돌기는 상기 돌출날개에 의한 상기 발포소재의 토출노즐 측 이동에 대항하여 상기 발포소재가 상기 공급관 연결부 측으로 이동되도록 하는 경사면을 갖는 것이 발포소재의 와류 형성에 도움이 되어 교반 효과를 향상시킬 수 있다.Here, the agitating projection has an inclined surface that allows the foamed material to move toward the supply pipe connection portion against the movement of the foamed material toward the discharge nozzle by the protruding blades, which contributes to the formation of a vortex of the foamed material, .

본 발명은 콤팩트한 구조로써 발포소재의 교반 효과를 극대화한다.The present invention maximizes the stirring effect of the foamed material with a compact structure.

도 2는 결합 사시도이며,
도 3은 본 믹싱헤드가 지지부에 설치되었을 때의 모습을 나타낸 종단면도이다.1 is an exploded perspective view of a mixing head according to the present invention,

도 1은 본 발명에 따른 믹싱헤드의 분해 사시도이며, 도 2는 결합사시도이다. 이들 도면에 도시된 바와 같이, 본 믹싱헤드는 발포소재가 교반되는 공간을 형성하는 하우징(100)과, 하우징(100) 내부에 동심적으로 삽입되어 발포소재를 교반하는 임펠러(200)로 이루어진다.FIG. 1 is an exploded perspective view of a mixing head according to the present invention, and FIG. 2 is an assembled perspective view. As shown in these drawings, the mixing head includes a housing 100 forming a space in which a foamed material is stirred, and an impeller 200 concentrically inserted in the housing 100 to stir the foamed material.

하우징(100)은 높이방향 축선을 따라 연장된 관상의 원통부(110)를 갖는다. 원통부(110)의 측벽에는 높이방향을 따라 소정 간격을 두고 배치되는 적어도 하나의 관통공(111)이 형성된다. 관통공(111)은 같은 높이 위치에서 원주방향을 따라 복수 개가 형성될 수 있다. 이러한 관통공(111)에는 교반돌기(300)가 삽입 장착된다. 관통공(111)과 교반돌기(300) 사이에는 기밀을 위한 실(seal)이 설치될 수 있다.The housing 100 has a tubular cylindrical portion 110 extending along the height direction axis. At least one through hole 111 is formed on the side wall of the cylindrical portion 110 at a predetermined interval along the height direction. A plurality of through holes 111 may be formed along the circumferential direction at the same height position. In this through hole 111, a stirring protrusion 300 is inserted and mounted. A seal for airtightness may be provided between the through hole 111 and the stirring protrusion 300.

원통부(110)의 상단부는 후술할 지지부(500)와 결합되어 발포소재 공급관(510, 520)과 연결되는 플랜지 형태의 연결부(120)가 형성된다. 연결부(120)에는 복수의 체결공(121)이 원주방향을 따라 소정의 간격을 두고 축선방향을 따라 관통되어 형성된다.The upper end of the cylindrical portion 110 is formed with a flange-shaped connection portion 120 connected to the foam material feed pipes 510 and 520 by being coupled with the support portion 500 to be described later. A plurality of fastening holes 121 are formed in the connection part 120 so as to penetrate along the axial direction at predetermined intervals along the circumferential direction.

원통부(110)의 하부에는 나선(113)이 높이방향을 따라 소정 길이만큼 형성되며, 여기에 발포소재의 혼합액이 분사되는 토출노즐(130)이 결합된다. 분사노즐(130)은 발포소재 혼합액이 분사되는 분사구(131)를 갖는다. At the lower part of the cylindrical part 110, a spiral 113 is formed along the height direction by a predetermined length, and the discharge nozzle 130 through which the mixed liquid of the foamed material is sprayed is coupled. The injection nozzle 130 has an injection port 131 through which the mixed material of the foamed material is injected.

이러한 하우징(100)의 내부에는 임펠러(200)가 동심적으로 삽입된다. 임펠러(200)는 원기둥형상의 임펠러 본체(210)를 갖는다. 임펠러 본체(210)의 상단부 축심영역에는 모터의 구동축(410)이 장착되기 위한 축삽입공(211)이 소정 깊이로 형성된다.The impeller 200 is concentrically inserted into the housing 100. The impeller 200 has a cylindrical impeller body 210. A shaft insertion hole 211 for mounting a motor drive shaft 410 is formed at a predetermined depth in an upper axial center region of the impeller body 210.

그리고 임펠러 본체(210)에는 외주면으로부터 반경방향 외측으로 돌출되는 다수의 돌출날개(230)가 형성된다. 이러한 돌출날개(230)들은 판상이며, 원주방향 및 축선방향을 따라 소정 간격을 두고 분산 배치된다. 돌출날개(230)의 형상은 변경가능하다.The impeller main body 210 is formed with a plurality of protruding blades 230 projecting radially outward from the outer circumferential surface. These protruding blades 230 are plate-shaped and are dispersed and arranged at predetermined intervals along the circumferential direction and the axial direction. The shape of the protruding blade 230 can be changed.

돌출날개(230)는 임펠러(200)의 회전 시 발포소재가 토출노즐(130) 측으로 유동되도록 하기 위해, 하부에 경사면(231)이 형성된다. 즉, 도 1에서와 같이 하부 경사면(231)이 우측 사선방향으로 경사지게 마련되었을 경우, 임펠러(200)가 반시계방향으로 회전하면 발포소재는 토출노즐(130) 측으로 유동된다.The protruding blades 230 are formed with an inclined surface 231 at a lower portion thereof in order to allow the foamed material to flow toward the discharge nozzle 130 when the impeller 200 rotates. 1, when the lower inclined surface 231 is inclined in the right diagonal direction, when the impeller 200 rotates counterclockwise, the foamed material flows to the discharge nozzle 130 side.

여기서, 돌출날개(230)들은 원주방향 및 축선방향을 따라 행과 열이 평행하게 배치되도록 한다. 그리고 경사면(231)의 대향 측에는 임펠러(200)의 축선방향에 대해 가로방향으로 연장되는 수평판면(233)이 형성되도록 한다. 이에 따라, 본 임펠러(200)의 제조는 용이해진다. Here, the protruding vanes 230 allow the rows and columns to be arranged in parallel in the circumferential direction and along the axial direction. A horizontal plate surface 233 extending in the transverse direction with respect to the axial direction of the impeller 200 is formed on the opposite side of the inclined surface 231. This makes it easy to manufacture the impeller 200.

즉, 본 임펠러(200)를 제조하기 위한 방법으로, 원기둥형태의 임펠러 소재를 준비한 다음 원주방향으로의 선반 가공 및 축방향으로의 엔드밀 가공으로 비교적 간단하게 판상의 돌출날개(230)가 형성된 임펠러(200)를 제조할 수 있다. 그리고 돌출날개(230)의 하부면을 모따기하여 경사면(230)을 형성할 수 있다.That is, as a method for manufacturing the impeller 200, a cylindrical impeller material is prepared, then an impeller having a plate-like protruding blade 230 is formed relatively easily by lathe processing in the circumferential direction and end milling in the axial direction (200) can be manufactured. The inclined surface 230 may be formed by chamfering the lower surface of the protruding blade 230.

도 3은 본 믹싱헤드가 지지부(500)에 설치되었을 때의 모습을 나타낸 종단면도이다. 지지부(500)에는 두 종류의 발포소재가 공급되는 제1공급관(510)과 제2공급관(520)이 설치되며, 중심축에는 모터(400)가 장착된다.3 is a longitudinal sectional view showing a state in which the present mixing head is installed in the supporter 500. Fig. The support part 500 is provided with a first supply pipe 510 and a second supply pipe 520 through which two kinds of foamed materials are supplied and a motor 400 is mounted on the center axis.

모터(400)의 구동축(410)은 임펠러(200)의 축삽입공(211)에 결합된다. 임펠러(200)는 모터의 구동에 의해 축선을 중심으로 회전될 수 있다. 그리고 하우징(100)은 연결부(120)의 체결공(121)에 체결핀(123)이 삽입되어 지지부(500)에 지지된다.The driving shaft 410 of the motor 400 is coupled to the shaft insertion hole 211 of the impeller 200. The impeller 200 can be rotated around the axis by driving of the motor. The housing 100 has a fastening pin 123 inserted into the fastening hole 121 of the connecting part 120 and is supported by the supporting part 500.

교반돌기(300)는 하우징(100)의 관통공(111)을 통해 돌출날개(230)의 높이방향 이격 공간 사이에 설치되어 도 3과 같은 종단면도를 나타낸다.The stirring projections 300 are longitudinal cross-sectional views as shown in FIG. 3, which are installed between the spaces in the height direction of the protruding vanes 230 through the through holes 111 of the housing 100.

이러한 구조에 의해, 발포소재들은 제1공급관(510) 및 제2공급관(520)을 통해 임펠러(200)와 하우징(100) 사이의 유동공간으로 유입되며, 임펠러(200)의 회전에 의해 교반된 후 분사구(131)를 통해 분사된다.With this structure, the foamed materials are introduced into the flow space between the impeller 200 and the housing 100 through the first supply pipe 510 and the second supply pipe 520, and the foamed materials are agitated by the rotation of the impeller 200 And is injected through the post-injection opening 131.

이때, 교반돌기(300)는 임펠러(200)의 회전에 의해 유동되는 발포소재에 와류가 형성되도록 하여 본 믹싱헤드의 교반 효과를 극대화한다. 여기서, 교반돌기(300)는 돌출날개(230)에 의한 발포소재의 토출노즐(130) 측 이동에 대항하여 발포소재가 연결부(120) 측으로 이동되도록 하는 경사면을 갖도록 하는 것이 더 강력한 와류를 형성할 수 있어 바람직하다.At this time, the agitation protrusion 300 forms a vortex in the foamed material flowing by the rotation of the impeller 200, thereby maximizing the agitation effect of the present mixing head. Here, the stirring protrusion 300 has a slope that allows the foam material to move toward the connection part 120 against the movement of the foam material by the protruding vane 230 toward the discharge nozzle 130, thereby forming a stronger vortex .

이와 같이, 본 발명에 따른 돌출날개(230)들은 원주방향 및 축선방향을 따라 행과 열이 평행하게 배치되어 임펠러(200)의 제조가 용이하고, 또 이러한 돌출날개(230)의 축선방향 사이 간격에 교반돌기(300)를 배치하여 전체적인 구조를 콤팩트하게 구성함과 동시에 발포소재의 교반 효과를 극대화하는 효과를 발휘한다.As described above, the protruding vanes 230 according to the present invention are arranged such that the rows and the columns are arranged in parallel in the circumferential direction and the axial direction to facilitate the manufacture of the impeller 200, and the interval between the axial directions of the protruding vanes 230 The stirring protrusions 300 are arranged in the center of the main body 100, thereby achieving a compact overall structure and maximizing the stirring effect of the foamed material.
