본 발명은 응집제 혼합장치에 관한 것으로, 더욱 상세하게는, 응집제의 공급을 적은 노동력으로 공급하도록 하고, 응집제와 폐수의 혼합이 연속적으로 이루어짐으로 폐수와 응집제의 균일한 반응이 가능하도록 함과 아울러 응집효율을 향상시킬 수 있는 응집제 혼합장치를 제공함에 있다.
The present invention relates to a flocculant mixing device, and more particularly, to supply the flocculant with a small labor force, and to perform the coagulation of the flocculant and the wastewater in a continuous manner to enable uniform reaction between the wastewater and the flocculant and to coagulate the flocculant. It is to provide a flocculant mixing device that can improve the efficiency.

일반적으로, 폐수를 처리하기 위하여 중성 무기계의 응집제 등을 폐수에 혼합하게 되는데, 이는 응집교반조 또는 응집반응조에 폐수를 유입시킨 후 응집제를 투입하여 혼합 또는 응집반응을 시키는 것이다.
In general, in order to treat the wastewater, a neutral inorganic flocculant or the like is mixed with the wastewater. This is to inject the wastewater into the coagulation stirring tank or the coagulation reaction tank and then add the flocculant to mix or aggregate the reaction.

도 1은 종래에 따른 폐수에 응집제를 혼합하도록 하는 장치를 설명하기 위한 도면이다.1 is a view for explaining an apparatus for mixing the flocculant in the wastewater according to the prior art.

도 1은 종래에 따른 폐수에 응집제를 혼합하도록 하는 장치를 설명하기 위한 도면이다.1 is a view for explaining an apparatus for mixing the flocculant in the wastewater according to the prior art.

도 1을 참고하면, 응집 혼합조(1) 내부로 원액공급펌프(2)에서 이송시킨 폐수가 공급됨과 아울러 상부에 설치된 응집제 공급부(3)에서 응집제가 공급되어지며, 상기 응집 혼합조(1)에 공급된 폐수와 응집제는 교반기(4)에 의해 교반되어 상호 혼합되어진다.Referring to FIG. 1, the wastewater transported from the stock solution supply pump 2 is supplied into the coagulation mixing tank 1, and the coagulant is supplied from the coagulant supply unit 3 installed at the upper portion thereof. The wastewater and flocculant supplied to the mixture are stirred by the stirrer 4 and mixed with each other.

또한, 상기 응집 혼합조(1)에서 혼합된 폐수와 응집제 혼합물은 응집 반응조(5)로 유동되어지고, 상기 응집 반응조(5)의 내부에 유입된 혼합물은 탈수조로 이동되어지는 것이다.In addition, the wastewater and the flocculant mixture mixed in the flocculation mixing tank 1 are flowed into the flocculation reaction tank 5, and the mixture introduced into the flocculation reaction tank 5 is moved to the dehydration tank.

그러나, 상기와 같은 응집제 혼합장치는, 응집 혼합조(1) 상부에 응집제 공급부(3)를 설치해야 됨으로 응집제 공급부(3)의 설치 위치가 높아져 응집제를 공급하는 과정이 힘들어서 작업자의 노동력이 많이 소요되는 문제점이 있다.However, in the coagulant mixing device as described above, the coagulant supplying part 3 must be installed on the coagulant mixing tank 1, so that the installation position of the coagulant supplying part 3 becomes high, and the process of supplying the coagulant is difficult, which requires a lot of labor of the worker.
