Description

실험용 교반기{A VORTEXER FOR EXPERIMENTATION}Experimental Stirrer {A VORTEXER FOR EXPERIMENTATION}

본 고안은 각종 실험용 액체를 교반 혼합하여 주는 교반기에 관한 것으로서, 더욱 상세하게는 일반 화학실험 또는 화학실험 기자재 또는 제약회사 실험실 및 학교에서 주로 많이 쓰이며 화학제품 생산 시약, 시료, 원료 등의 샘플을 희석(dilute)하거나 섞음(mix), 교반(stir)시에 사용되는 교반기 구조에 관한 것이다.The present invention relates to an agitator that stirs and mixes various experimental liquids, and more particularly, is commonly used in general chemical experiments or chemical experiment equipment or pharmaceutical company laboratories and schools, and dilutes samples of chemical production reagents, samples, and raw materials. The present invention relates to a stirrer structure used for dilute, mix, and stir.

일반적으로, 생물발효공정나 화학반응공정에서는 원하는 반응을 최적의 상태에서 정확하게 유지하기 위해 발효조내의 온도, pH, 용존산소량, 영양물질의 농도 등과 같은 환경변수를 적절히 조절해 주어야만 한다. 이러한 환경변수와 미생물의 발효대사활동을 최대로 만들어 주기 위해서는 배양액을 적절히 교반시켜 주어야 한다.In general, in biofermentation or chemical reaction processes, environmental variables such as temperature, pH, dissolved oxygen, concentration of nutrients, etc. in fermenter must be properly adjusted to maintain the desired reaction correctly and optimally. In order to maximize these environmental variables and the fermentation metabolism of microorganisms, the culture medium should be agitated properly.

이에 사용되는 통상의 교반기는 구동용 모터와 동력전달장치, 교반기 주축, 랙크등으로 구성된다. 발효조내의 배양액을 교반시키는 것은 일반적인 발효반응에서 산소가 필요하기 때문에, 발효조 외부에서 배양액속으로 공급하는 공기나 산소를 세분 및 분산시켜 배양액중의 산소공급속도를 높이고, 배양액 전체를 적절히 혼합하여 균일한 상태의 최종 물질을 얻기 위함이다.A conventional stirrer used for this is composed of a driving motor, a power transmission device, a stirrer spindle, a rack and the like. Stirring the culture medium in the fermentation tank requires oxygen in a general fermentation reaction. Therefore, by subdividing and dispersing air or oxygen supplied to the culture medium from the outside of the fermentation tank, the oxygen supply rate in the culture medium is increased, and the entire culture medium is appropriately mixed to achieve uniformity. To get the final material in the state.

그러나, 종래에 사용되어지는 교반기의 경우 교반되어질 용기의 형태(시험관, 앰플, 플라스크, 비이커 등)에 따라 각기 다른 종류의 랙크를 장착해주어야 하는 불편이 있었으며, 교반기에서 발생되어지는 진동력에 의해 교반기의 위치가 조금씩 이동되어짐으로 인해 실험용 액체가 담겨져 있는 용기가 낙하되어 파손되는등의 문제점이 발생하였다.However, in the case of a stirrer used in the prior art, it was inconvenient to install different kinds of racks according to the type of container to be stirred (test tube, ampoule, flask, beaker, etc.), and the stirrer was caused by the vibration force generated in the stirrer. As the position of is moved little by little, the problem that the container containing the experimental liquid falls and is damaged is caused.

본 발명은 상기한 종래 문제점을 개선하기 위해 제안된 것으로서, 교반작업에 따른 내부진동력이 전달되어지더라도 교반기가 안정적으로 지지되어질 수 있도록 하는데 목적이 있다.The present invention has been proposed to improve the above-mentioned conventional problems, and an object thereof is to enable the stirrer to be stably supported even when the internal vibration force is transmitted by the stirring operation.

또한, 본 발명의 다른 목적으로는 여러가지 형태의 실험용기가 공통적으로 수용가능한 랙크구조를 제공함으로서 실험의 효율을 개선시키는데 있다.In addition, another object of the present invention is to improve the efficiency of the experiment by providing a rack structure that can be commonly accommodated in various types of experimental containers.

또한, 본 발명의 또다른 목적으로는 내부 마이크로 스위치의 위치를 변경함으로서 교반기의 전체적인 높이를 감소시키도록 하여 안정된 작동을 도모하는데 있다.In addition, another object of the present invention is to reduce the overall height of the stirrer by changing the position of the internal micro switch to achieve a stable operation.

(2) and the control switch 3 for speed control were provided, and the leg part 4 protruded in the predetermined | prescribed place at the bottom surface. The upper surface of the rack 10 has a test tube receiving groove 11 is formed in the center to enable the seating of the test tube 15, as shown in Figure 4a, in a radial direction around the test tube receiving groove (11) As shown in 4b, a small container in the form of an ampoule 16 is laid down and a large number of ampoule accommodation grooves 12 are formed, and elastic rubber bands 13 are provided along the periphery, so that various types of containers are seated. It can be fixed stably. In addition, a plurality of rubber tiles 18 forming a flat surface is attached to the upper surface of the rack 10 so that the flask 17 can be stably seated as shown in FIG. 4C.

한편, 교반기 본체(1)의 내부구성은 도 2에 도시된 바와같이 구동모터(M)와, 상기 구동모터(M)의 구동축(21)상에 편심 결합되어진 연결부재(22)와, 상기 연결부재(22)의 회전을 소정각도범위내에서 억제하기 위한 코일스프링(23)과, 상하방향으로 간격유동이 가능한 상태에서 상기 모터 구동축(21)의 하단과 접촉되어져 있으며 그 일단이 측상방으로 연장 형성되어진 판스프링(24)과, 상기 판스프링(24)의 이격 유동에 의해 전원의 인가가 선택적으로 이루어지는 리미트스위치(25) 등이 구성되었다.On the other hand, the internal configuration of the agitator body 1 is a drive motor (M), as shown in Figure 2, the connecting member 22 is eccentrically coupled on the drive shaft 21 of the drive motor (M), the connection The coil spring 23 for suppressing the rotation of the member 22 within a predetermined angle range, and in contact with the lower end of the motor drive shaft 21 in the state in which the clearance flow in the vertical direction, one end thereof extends laterally The formed leaf spring 24 and the limit switch 25 etc. which apply power selectively by the spaced flow of the leaf spring 24 were comprised.

도면중 미설명 부호 26은 구동축(21)을 지지하는 지지프레임을 나타낸다.In the figure, reference numeral 26 denotes a support frame for supporting the drive shaft 21.

또한, 교반기 본체(1)의 저면에 돌설된 다리부(4)는 내부에 지지체(5)가 내설되어져 있는데, 상기 지지체(5)는 탄성스프링(6)의 탄성력을 받으며 지지되어지고, 상부에는 이탈방지너트(7)가 체결되어져 있다. 상기 다리부(4)와 지지체(5)는 진동전달을 최소화하기위해 고무재질로 이루어져 있다.In addition, the leg portion 4 protruding from the bottom of the stirrer body 1 has a support 5 therein, which is supported by the elastic force of the elastic spring 6, The release preventing nut 7 is fastened. The leg 4 and the support 5 is made of a rubber material to minimize vibration transmission.

이와같은 구성을 이루고 있는 본 발명 교반기의 동작에 따른 작용효과를 이하에서 살펴보기로 한다. The effect of the operation of the stirrer of the present invention having such a configuration will be described below.

먼저, 동작선택버튼(2)을 위쪽으로 눌러주어 "Continue" 모드를 선택하면 전원이 인가되어 바로 구동모터(M)가 동작되어지면서 구동축(21)을 회전시키게 되고, 이로인해 구동축(21) 상부에 편심 장착되어져 있는 연결부재(22)가 편심회동되어지게 된다. 이때, 연결부재(22)는 편심력에 의한 유동이 이루어질 뿐 코일스프링(23)의 구속력에 의해 회동은 소정범위내에서만 이루어지게 된다.First, when pressing the operation selection button (2) upward to select the "Continue" mode, the power is applied to the drive motor (M) immediately operates to rotate the drive shaft 21, thereby driving the upper drive shaft 21 The connecting member 22 mounted on the eccentric is to be eccentrically rotated. At this time, the connection member 22 is made only by the flow of the eccentric force is rotated by the restraining force of the coil spring 23 is made only within a predetermined range.

따라서, 연결부재(22)의 상단에 결합되어져 있는 랙크(10)에는 이러한 유동력이 전달되어짐으로서 샘플에 대한 교반이 효과적으로 이루어지게 됨을 알 수 있다.Therefore, it can be seen that the rack 10 is coupled to the upper end of the connecting member 22 such that the flow force is transmitted, thereby effectively stirring the sample.

이와같이 랙크(10)의 진동에 의한 교반동작이 이루어지는 가운데 작업자는 조절스위치(3)를 적절하게 조절함으로서 최적의 교반작업을 수행할 수 있게된다.In this way, while the stirring operation is performed by the vibration of the rack 10, the operator can perform the optimum stirring operation by appropriately adjusting the control switch (3).

한편, 작업자가 동작선택버튼(2)을 아래쪽으로 눌러주어 "Touch"모드를 선택하게 되면 전원은 바로 인가되어지지 않고 내부의 리미트스위치(25)에 의해 선택적으로 이루어지게 된다.On the other hand, when the operator presses the operation selection button (2) downward to select the "Touch" mode, the power is not applied directly, it is selectively made by the internal limit switch 25.

즉, 이러한 터치모드에서는 랙크(10)에 가압력이 전달되어진 상태에서만 교반동작이 이루어지게 되는 것으로, 샘플이 들어있는 시험관을 랙크(10)의 시험관수용홈(11)에 올려놓고 눌러주게 되면 그 가압력에 의해 연결부재(22)와 모터구동축(21)이 함께 눌려지게 되면서 구동축(21)의 하단이 판스프링(24)을 눌러주게 된다. 이로 인하여 측상방으로 연장되어져 있는 판스프링(24)의 일단이 리미트스위치(25)를 눌러주게 되고, 이에따라 구동모터(M)에 전원이 인가되면서 동작이 발생되어지게 된다.That is, in such a touch mode, the stirring operation is performed only when the pressing force is transmitted to the rack 10, and when the test tube containing the sample is put on the test tube receiving groove 11 of the rack 10 and pressed, the pressing force is applied. By the connecting member 22 and the motor drive shaft 21 is pressed together, the lower end of the drive shaft 21 is pressed by the leaf spring 24. As a result, one end of the leaf spring 24 extending laterally presses the limit switch 25. Accordingly, power is applied to the driving motor M to generate an operation.

그리고 상기 시험관에 의한 랙크(10)의 가압력이 해제되면 다시 판스프링(24)이 원위치되어지면서 리미트스위치(25)에 대한 누름력이 해제되어지면서 구동모터(M)로의 전원공급이 중단되어지게 되는 것이다.When the pressing force of the rack 10 is released by the test tube, the leaf spring 24 is released again, and the pressing force on the limit switch 25 is released, thereby stopping the power supply to the driving motor M. will be.

이와같은 선택적인 동작이 이루어짐에 있어서 종래에는 리미트스위치(25) 및 스위치를 단속하는 부재가 구동모터(M)의 하부에 설치되어져 있음으로 인하여 교반기 본체(1)의 전체적인 설계높이가 불필요하게 증가하였으나, 본 발명에서는 이러한 부재들을 측방으로 위치시킴으로서 교반기 본체(1)의 높이를 낮출 수 있게됨을 부가적인 특징으로 한다.In this selective operation, the overall design height of the stirrer body 1 is unnecessarily increased because the limit switch 25 and the member for controlling the switch are installed in the lower part of the driving motor M. In the present invention, it is an additional feature to be able to lower the height of the stirrer body (1) by placing these members laterally.

한편, 본 발명의 주된 특징으로는 다리부(4)구조를 들수있다.On the other hand, the main feature of the present invention is the structure of the leg portion (4).

즉, 종래에는 교반기 내부로 부터 발생되는 진동 유동력이 교반기 본체(1)로 전달되어짐에 따라 교반기의 위치가 조금씩 이동되어졌으나, 본 발명의 구조에 따르면 도 3에 도시된 바와같이 전달되어지는 진동력에 의해 일측의 다리부(4)가 지면과 이격되어지더라도 내설되어진 지지체(5)가 탄성스프링(6)의 탄성력에 의해 지면과 계속적인 접촉상태를 유지하고 있음으로 인하여 보다 안정적인 지지가 가능하게 됨을 알 수 있다.That is, in the related art, the position of the stirrer is moved little by little as the vibration flow force generated from the inside of the stirrer is transmitted to the stirrer body 1, but according to the structure of the present invention, the jin is transmitted as shown in FIG. Even if the leg portion 4 on one side is separated from the ground by the power, the support 5, which is built in, is maintained in continuous contact with the ground by the elastic force of the elastic spring 6, thereby enabling more stable support. It can be seen that.

그리고, 상기에서 본 발명의 특정한 실시예가 설명 및 도시되었지만 본 발명의 교반기 구조가 당업자에 의해 다양하게 변형되어 실시될 가능성이 있는 것은 자명한 일이다.And while specific embodiments of the present invention have been described and illustrated above, it is obvious that the stirrer structure of the present invention may be variously modified and implemented by those skilled in the art.

그러나, 이와 같은 변형된 실시예들은 본 발명의 기술적 사상이나 전망으로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시예들은 본 발명의 첨부된 특허청구범위 안에 속한다 해야 할 것이다.However, such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended claims of the present invention.

이상에서 살펴본 바와같은 본 발명은, 교반기의 동작에 따른 내부진동력이 전달되어지더라도 교반기가 안정적으로 지지되어질 수 있는 다리부 구조를 제공함과 함께 여러가지 형태의 실험용기(시험관, 앰플, 플라스크 등)가 공통적으로 수용가능한 랙크구조를 이룸으로서 교반에 따른 실험작업을 보다 용이하게 이룰 수 있게된다.As described above, the present invention provides a leg structure in which the stirrer can be stably supported even when the internal vibration force is transmitted according to the operation of the stirrer. By forming a commonly acceptable rack structure it is possible to more easily achieve the experimental work by stirring.

이와함께 교반기 본체의 전체적인 설계높이를 저감시킬 수 있게됨으로서 제품의 작동안정을 도모하는 이점을 나타내게 된다.Along with this, it is possible to reduce the overall design height of the agitator body, thereby exhibiting the advantages of improving the operation of the product.
