Description

교반 스크류{A mixing screw}A mixing screw < RTI ID = 0.0 >

본 발명은 교반 스크류에 관한 것으로, 보다 상세하게는 모터의 과부하가 방지되면서도 교반물 중의 덩어리가 용이하게 풀어지고 교반물을 상하로 유동시킬 뿐 아니라 상측 및 하측의 교반물을 교반날개와 접하도록 이송시키면서 교반하여 교반효율이 향상되는 교반 스크류에 관한 것이다.
The present invention relates to a stirring screw, and more particularly, to a stirrer which is capable of preventing a motor from being overloaded, a lump in an agitated object is easily loosened, a stirring object is moved up and down, And stirring the mixture while stirring the mixture.

일반적으로 교반기는 물리적 또는 화학적 성질이 다른 2종 이상의 물질을 회전력을 이용하여 균일한 혼합상태로 만들기 위해 사용한다. 종래 교반기는 교반물이 채워지는 챔버와, 이 챔버 내부에 설치되며 모터의 회전축에 축결된 프로펠러 등과 같은 교반날개로 이루어진다. Generally, a stirrer is used to make two or more materials having different physical or chemical properties to be uniformly mixed using rotational force. Conventionally, an agitator is composed of a chamber filled with an agitated material, and a stirring blade such as a propeller built in the chamber and built on a rotating shaft of the motor.

그런데, 종래 교반기의 프로펠러와 같은 교반날개는 넓적한 형상으로 이루어져서 회전시 교반날개에 압력이 크게 작용하므로, 회전축에 회전력을 전달하는 모터 등에 과부하현상이 발생하기 쉽다. 이에 따라, 교반날개가 회전축에 나선형으로 일체로 이루어진 스크류가 사용되기도 한다. 하지만, 이와 같은 스크류는 챔버의 바닥면에 침전된 교반물은 교반할 수 없어서 교반효율이 저하되는 문제가 있다. 또한, 접착용 풀과 같은 교반물에는 덜 풀어진 덩어리가 많이 있는데, 이와 같은 덩어리는 스크류가 회전되더라도 교반날개에 의해 이송될 뿐 잘 풀어지지 않는 문제가 있다. 이에 따라, 벽지에 풀을 도포하더라도 덩어리가 그대로 남아서 도배된 벽지가 울퉁불퉁하게 되는 문제가 있다. Conventionally, a stirring blade such as a propeller of a stirrer is formed in a wide shape, and pressure is largely applied to the stirring blade at the time of rotation, so that an overload phenomenon is likely to occur in a motor that transmits rotational force to the rotation shaft. Accordingly, a screw in which the stirring wing is spirally formed integrally with the rotary shaft is used. However, in such a screw, there is a problem that the agitated product precipitated on the bottom surface of the chamber can not be agitated and the stirring efficiency is lowered. In addition, there are many loosened loaves in the agitated product such as the adhesive paste. Such loaves are conveyed by the stirring wing even if the screw is rotated, but are not loosened. As a result, there is a problem that even if the grass is applied to the wallpaper, the lumps remain and the roughened wallpaper becomes uneven.

상술한 본 발명의 목적, 특징들 및 장점은 다음의 상세한 설명을 통하여 보다 분명해질 것이다. 이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.The objects, features and advantages of the present invention will become more apparent from the following detailed description. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1 내지 도 2는 본 발명의 바람직한 일실시예에 따른 교반 스크류를 도시한 도면이다. 도시된 바와 같이, 본 발명의 일실시예에 따른 교반 스크류는 모터(3)의 구동축(4)에 결합되는 회전축부재(10)와, 이 회전축부재(10)에 나선형으로 구비된 교반날개(20)와, 이 교반날개(20)의 외측단에 코일 형태로 연속 결합된 교반코일(30)과, 상기 교반날개(20)의 상하단에서 각각 절곡된 상부 및 하부절곡날(40,50)을 포함하여 구성된다. 1 and 2 are views showing a stirring screw according to a preferred embodiment of the present invention. The stirring screw according to an embodiment of the present invention includes a rotating shaft member 10 coupled to the driving shaft 4 of the motor 3 and a stirring blade 20 provided spirally on the rotating shaft member 10, A stirring coil 30 continuously connected to the outer end of the stirring vane 20 in the form of a coil and upper and lower bending blades 40 and 50 bent at the upper and lower ends of the stirring vane 20, .

우선, 이와 같이 구성된 본 발명의 일실시예에 따른 교반 스크류는 도 2에서와 같이 교반용 챔버(1)에 설치되어 챔버(1)에 투입된 교반물(6)을 교반시키는데, 도시된 실시예에서는 챔버(1)의 하측에 모터(3)가 브래킷(5)에 의해 설치되고 이 모터(3)의 구동축(4)이 챔버(1) 내부로 수직 연장된 것을 예시하였으나 경우에 따라 상기 구동축(4)이 수평하게 형성될 수도 있다. 또한, 챔버(1)는 바닥면의 중앙에 모터(3)의 구동축(4)을 지지하는 원형의 지지돌부(2)가 돌출 형성된다. 그리고 상기 교반물(6)은 다양한 물질로 이루어질 수 있지만, 본 발명의 교반 스크류는 특히 점도가 비교적 높은 페이스트 상태로 이루어진 접착용 풀에 물을 섞어 도배용 풀을 만들 때 사용된다. 2, the stirring screw according to an embodiment of the present invention is installed in the stirring chamber 1 to stir the stirring object 6 charged into the chamber 1. In the illustrated embodiment, The motor 3 is provided by the bracket 5 on the lower side of the chamber 1 and the drive shaft 4 of the motor 3 extends vertically into the chamber 1. However, May be formed horizontally. In the chamber 1, a circular support projection 2 for supporting the drive shaft 4 of the motor 3 is formed at the center of the bottom surface. Although the agitating material 6 may be made of various materials, the agitating screw of the present invention is particularly used in making paste for pooling by mixing water into an adhesive paste having a relatively high viscosity.

상기 회전축부재(10)는 모터(3)의 구동축(4)에 결합되어 모터(3)의 구동에 의해 회전된다. 이와 같은 회전축부재(10)는 하단에 모터(3)의 구동축(4)이 끼워지는 끼움홈(11)이 상측으로 연장 형성된다. 그리고 회전축부재(10)에는 지름방향으로 결합공(12)이 형성되고 이 결합공(12)에 구동축(4)을 관통하는 결합핀(13)이 끼워져서 회전축부재(10)가 구동축(4)에 고정된다. The rotating shaft member 10 is coupled to the driving shaft 4 of the motor 3 and rotated by driving the motor 3. In such a rotary shaft member 10, a fitting groove 11 in which the driving shaft 4 of the motor 3 is fitted is formed at the lower end to extend upward. The engaging hole 12 is formed in the rotating shaft member 10 in the radial direction and the engaging pin 13 penetrating the driving shaft 4 is inserted into the engaging hole 12 so that the rotating shaft member 10 is engaged with the driving shaft 4, Respectively.

상기 교반날개(20)는 회전축부재(10)의 외주면에서 측방으로 돌출되어 나선형으로 연장된다. 이때, 교반날개(20)의 내경이 회전축부재(10)의 외경과 동일하게 형성되어 교반날개(20)의 내측면 전체가 회전축부재(10)에 직접 결합될 수도 있지만, 도시된 실시예에서는 교반날개(20)의 내경이 회전축부재(10)의 외경보다 크게 형성된 것을 예시하였다. 그리고 교반날개(20)의 내측면에서 내측으로 일정간격 이격된 다수의 내향지지돌기(22)가 회전축부재(10)의 외주면에 용접 등에 의해 결합된다. 이에 따라, 회전축부재(10)와 교반날개(20) 사이에 개구부(23)가 연속적으로 형성된다. 한편, 교반날개(20)의 외측단에는 다수의 통공(21)이 일정간격 이격 형성된다. The stirring vanes 20 project sideways from the outer circumferential surface of the rotating shaft member 10 and extend spirally. At this time, the inner diameter of the stirring vane 20 is formed to be equal to the outer diameter of the rotating shaft member 10 so that the entire inner surface of the stirring vane 20 can be directly coupled to the rotating shaft member 10, And the inner diameter of the blade 20 is formed to be larger than the outer diameter of the rotating shaft member 10. A plurality of inwardly supporting protrusions 22 spaced inwardly from the inner surface of the stirring vane 20 at a predetermined interval are joined to the outer circumferential surface of the rotating shaft member 10 by welding or the like. Thereby, the opening 23 is continuously formed between the rotating shaft member 10 and the stirring vane 20. On the other hand, at the outer end of the stirring vane 20, a plurality of through holes 21 are formed with a predetermined spacing.

상기 교반코일(30)은 금속와이어를 교반날개(20)의 통공(21)들을 코일 형태로 연속 통과시켜 결합시킨 것이다. 이와 같은 교반코일(30)은 금속와이어가 교반날개(20)의 각 통공(21)들에 끼워져서 일정간격으로 벌어진 코일 형태이므로 일반적인 코일 및 양단부만 고정된 코일과 달리 외력에 의해 신축되지 않는다. 이에 따라, 회전축부재(10)의 회전에 따라 교반물(6)에 의해 가압되더라도 교반코일(30)의 형상이 거의 그대로 유지되므로 교반코일(30)의 기능저하가 발생되지 않는다. The stirring coil 30 is formed by continuously passing the metal wires through the through holes 21 of the stirring vane 20 in the form of a coil. Since the metal wire is inserted into the through holes 21 of the stirring vane 20 and is in the form of a coil spread at regular intervals, unlike a conventional coil and a coil having only both ends, the stirring coil 30 is not expanded or contracted by an external force. Accordingly, even if the stirring coil 30 is pressed by the stirring object 6 in accordance with the rotation of the rotating shaft member 10, the shape of the stirring coil 30 is substantially maintained, so that the function of the stirring coil 30 does not deteriorate.

상기 상부절곡날(40) 및 하부절곡날(50)은 교반날개(20)의 상단 및 하단에서 각각 상향 및 하향 절곡 형성된다. 이때, 상부 및 하부절곡날(40,50)은 교반날개(20)에서 일체로 절곡 형성될 수도 있지만 도시된 실시예에서는 교반날개(20)와 별체로 이루어져서 고정볼트(60)와 너트(61)에 의해 교반날개(20)에 착탈가능하게 결합된 것을 예시하였다. 이에 따라, 상부 및 하부절곡날(40,50)의 마모 등에 의한 교체가 용이하다. The upper bending blade 40 and the lower bending blade 50 are bent upward and downward at the upper and lower ends of the stirring vane 20, respectively. At this time, the upper and lower bending blades 40 and 50 may be integrally bent in the stirring vane 20, but in the illustrated embodiment, the upper and lower bending blades 40 and 50 are separate from the stirring vane 20 and are fixed to the fixing bolt 60 and the nut 61, And is detachably coupled to the stirring vane 20 by means of a screw. Accordingly, the upper and lower bending blades 40 and 50 can be easily replaced due to wear and the like.

이와 같이 구성된 본 발명의 일실시예에 따른 교반 스크류의 작동을 설명하면, 우선 챔버(1)에 접착용 풀과 물을 채우는데 풀은 바닥으로 가라앉고 물은 풀의 상측에 위치된다. 그리고 모터(3)를 구동시키면 회전축부재(10)가 회전됨에 따라 교반물(6)인 접착용 풀과 물이 교반날개(20)에 의해 섞이게 된다. 이때, 배경기술에서 언급한 바와 같이 접착용 풀에는 덜 풀어진 덩어리(7)들이 많이 있는데, 이와 같은 덩어리(7)들은 교반날개(20) 외측단에 구비된 교반코일(30)에 부딪치면서 풀어지게 된다. 그리고 챔버(1) 상측의 교반물(6)이 상부절곡날(40)에 부딪치면서 상하로 유동될 뿐 아니라 하측으로 이동되어 교반날개(20)와 직접 접촉됨에 따라 교반이 더욱 효과적으로 이루어진다. 또한, 접착용 풀에 섞인 상기 덩어리(7) 중 챔버(1) 하측에 가라앉은 덩어리(7)는 하부절곡날(50)에 의해 부유하므로 보조교반날개(30)에 의해 풀어지고 교반날개(20)에 의해 교반된다. 따라서 교반물(6) 중 덜 풀어진 덩어리(7)가 효과적으로 풀어지면서 챔버(1) 상측 및 하측의 교반물(6)을 더욱 균일하게 교반되어 교반효율이 향상된다. The operation of the stirring screw according to one embodiment of the present invention will be described. First, the chamber 1 is filled with the adhesive paste and water. The paste sinks to the bottom and the water is positioned on the upper side of the pool. When the motor 3 is driven, as the rotating shaft member 10 is rotated, the adhesive paste and the water, which are the stirring object 6, are mixed by the stirring vane 20. At this time, as mentioned in the background art, there are many loosened loops 7 in the adhesive pool, and these loops 7 collide with the stirring coil 30 provided at the outer end of the stirring vane 20, do.
