본 발명은 혼합기에 관한 것으로, 특히 서로 다른 종류의 입상물 또는 분상물등을 용기안에 넣고 그 내부에 설치된 회전날개를 회전시켜 혼합실내의 분상물을 교반시켜 혼합하는 혼합기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mixer, and more particularly, to a mixer in which different kinds of particulate matter or powdery matter are put in a container, and the rotary blades installed therein are rotated to stir and mix the powdery matter in the mixing chamber.
여러가지 종류의 분체 조성물을 한데 섞어 혼합물을 만들때 사용하는 혼합기는 일반적으로 원통형 용기와, 다수개의 회전날개로 이루어지고 상기 용기의 회전축상에 회전가능하게 설치된 회전날개 조립체로 구성되어, 이 회전날개 조립체가 회전하면서 용기내의 분체 조성물을 교반시켜 서로 혼합시켜 주는 구조로 되어 있다.A mixer used to make a mixture by mixing various kinds of powder compositions is generally composed of a cylindrical container and a rotor blade assembly composed of a plurality of rotor blades and rotatably installed on the axis of rotation of the vessel. While rotating, the powder composition in the container is stirred and mixed with each other.
그런데 상기 혼합기는 그 회전날개가 단순한 평면 형상으로 되어 회전축에 부착설치되어 있기 대문에 조성물을 균일하게 혼합시켜 줄수 없었고 따라서 혼합물의 조성비가 부분적으로 불균일한 문제점이 있었다.However, the mixer could not be uniformly mixed with the composition because the rotor blade is a simple planar shape attached to the rotating shaft, there was a problem that the composition ratio of the mixture is partially nonuniform.
이러한 문제점을 해소하기 위해 회전및 전동식 혼합기가 제안되었는데, 이 회전및 진동식 혼합기는 회전날개 조립체가 용기내부에서 회전하면서 조성물을 교반시켜 줌과 동시에 용기 자체가 좌우 또는 상하로 요동하면서 용기내부의 조성물을 혼합시켜 주도록 되어 있다.In order to solve this problem, a rotary and electric mixer has been proposed. The rotary and vibratory mixer stirs the composition while the rotor blade assembly rotates inside the container while simultaneously shaking the composition inside the container while the container itself swings left and right. It is to be mixed.
그런데 이와같은 회전및 진동식 혼합기는 용기자체를 좌우 또는 상하로 요동시켜 주는 부수적인 장치가 필요하게 됨으로써 전체적인 구조가 복잡해지고 따라서 고장 발생의 빈도가 높아져 유지 보수에 드는 비용이 높은 단점이 있었다.However, such a rotary and vibratory mixer requires an additional device for rocking the container itself left and right or up and down, and thus, the overall structure is complicated, and thus, the frequency of failures is high, resulting in high maintenance costs.
이에 본 발명은 상기한 종래의 혼합기가 가진 문제점을 해소하기 위해 안출된 것으로, 구조가 간단하면서도 분상물등을 균일하게 혼합시켜 주는 회전 교반식 혼합기를 제공하는데 그 목적이 있다.The present invention has been made to solve the problems of the conventional mixer described above, the object of the present invention is to provide a rotary stirring mixer that has a simple structure and uniformly mixed powdered matter.

또한 상기 각 회전날개(23)(33)는, 제2도및 제3도에 도시된 바와같이, 외측면(21a)(31a)이 축방향의 소정폭(W)에 걸쳐 점차적으로 용기 내벽(11a)과 소정 원호간(θ)만큼 접촉하도록된 구조로 되어 있다.In addition, as shown in FIGS. 2 and 3, each of the rotary blades 23 and 33 has an outer wall 21a, 31a gradually extending over the predetermined width W in the axial direction. 11a) and a predetermined circular arc θ are in contact with each other.
그리고 이 회전날개 조립체(20)는, 제1도에 도시된 바와같이, 용기(10)의 중심축 상에 배치되면서 그 회전축(22)의 양쪽 선단이 각각 용기 측벽(11b)에 베어링(25)을 매개로 하여 설치되는 한편, 한쪽 선단은 모우터(26)와 연결된 구조로 되어, 이 모우터(26)의 회전력으로써 용기(10)내에서 회전하도록 되어있다.As shown in FIG. 1, the rotary wing assembly 20 is disposed on the central axis of the container 10, and both ends of the rotary shaft 22 are connected to the container side wall 11b, respectively. On the other hand, the one end is connected to the motor 26 and is rotated in the container 10 by the rotational force of the motor 26.
그리고 용기(10)의 상단 측벽에는 투입구(13)가 형성되고 하단측벽(11)에는 배출구(14)가 형성되며 이 배출구(14)는 제5도에 도시된 바와같이 실린더(27)의 신축작동에 따라 링크부재(29a)(29b)를 매개로 선회운동을 하는 문(28)에 의해 개폐되도록 되어 있다.In addition, an inlet 13 is formed in the upper sidewall of the container 10 and an outlet 14 is formed in the lower side wall 11, and the outlet 14 is telescopic operation of the cylinder 27 as shown in FIG. 5. In accordance with the link members 29a and 29b, the door 28 is opened and closed by pivoting.
본 발명에 따른 혼합기의 제2실시예는, 제6도에 도시된 바와같이, 용기(40)의 내부가 상호 평행한 2개의 원통형 혼합실(41)로 구성되고 이들 각 원통형 혼합실(41a)(41b)에는 그 중심축상으로 상기 회전날개 조립체(20a)(20b)가 회전가능하게 설치되는 한편 이들 각 회전날개 조립체(20a)(20b)는 서로 반대방향으로 회전하도록 된 것에 특징이 있는 것이다.The second embodiment of the mixer according to the present invention, as shown in FIG. 6, consists of two cylindrical mixing chambers 41 in which the interior of the container 40 is parallel to each other, and each of these cylindrical mixing chambers 41a. The rotary blade assemblies 20a and 20b are rotatably installed on the central axis 41b while the rotary blade assemblies 20a and 20b are rotated in opposite directions.
이하, 본 발명에 따른 혼합기의 작동 및 효과를 설명한다.Hereinafter, the operation and effects of the mixer according to the present invention will be described.
본 발명에 따른 혼합기(1)의 투입구(23)를 통하여 혼합하고자 하는 몇가지 분상물을 혼합실(12)안으로 투입한 후 전원을 인가하여 모우터(26)를 회전시키면 회전날개 조립체(20)가 회전하면서 그 회전날개(23)(33)가 혼합실(12)내의 분상물을 교반시켜 주게 된다.After inserting some powder to be mixed into the mixing chamber 12 through the inlet 23 of the mixer 1 according to the present invention, the power is applied to rotate the motor 26 to rotate the rotor blade assembly 20. While rotating, the rotary blades 23 and 33 stir the powdered powder in the mixing chamber 12.
그런데 제1회전날개(23)는 제4(a)에 도시된 바와같이 회전하면서 분상물을 위로 퍼올림과 동시에 축방향으로 전진이송시켜 주게 되고, 이렇게 뒤집히면서 전진이송되는 분상물을 다시 제2회전날개(33)가 회전하면서 위로 퍼올림과 동시에 뒷쪽으로 후진 이송시켜 줌으로써 분상물을 골고루 혼합하게 되는 것이다.However, the first rotary blade 23 is rotated as shown in the fourth (a), while the powdered material is spun up while simultaneously moving forward in the axial direction. The two rotary blades 33 are rotated and raised, and at the same time, the backward movement to the rear is to mix the powder evenly.
이와같이 동일 회전축(22)상에 교대로 배치 고정된 제1회전날개(23)와 제2회전날개(33)가 상호 반대되는 교반동작을 교대로 행하게 됨으로써 혼합실(12)내의 분상물을 균일하게 혼합해 주게 되는 것이다.In this way, the first rotary blades 23 and the second rotary blades 33 which are alternately arranged and fixed on the same rotary shaft 22 alternately perform mutually stirring operations, thereby uniformly separating powders in the mixing chamber 12. It will be mixed.
특히, 본 발명에 따른 혼합기의 제2실시예의 경우 제6도에 도시된 바와같이 상기와 같은 구조의 회전날개 조립체(20)를 상호 평행하게 배치된 2개의 혼합실(41a)(41b)내에 각각 설치하여 상호 반대방향으로 회전시키면 더 많은 량의 혼합물을 더 높은 효율로 혼합해 줄 수 있다.In particular, in the case of the second embodiment of the mixer according to the present invention, as shown in FIG. 6, the rotor blade assembly 20 having the above structure is respectively arranged in two mixing chambers 41a and 41b arranged in parallel with each other. By installing and rotating in opposite directions, more mixtures can be mixed with higher efficiency.
이상에서 설명한 바와같이 본 발며엥 따른 혼합기는 용기를 흔들어 주거나 요동시켜 주는 용기 진동장치 없이도 회전날개의 소위, 쟁기식 교반 작동방식에 의해 분상물들을 균일하게 혼합해 줄수 있고, 진동장치 등과 같은 부속장치가 필요없기 때문에 상대적으로 고장발생 되는 낮은 실용적인 발명인 것이다.As described above, the mixer according to the baldungen can uniformly mix the powders by the so-called plow-type stirring operation of the rotary blade without the container vibrating device which shakes or shakes the container, and the accessory device such as the vibrating device. It is a low practical invention that is relatively troublesome because it is not necessary.
