상승스크류를 이용한 연속식 세척장치{Continuous washing device with rising screw}Continuous washing device with rising screw

본 발명은 상승스크류를 이용한 연속식 세척장치에 관한 것으로서, 더욱 상세하게는 세척조 내부 중앙에 수직으로 설치된 상승스크류 주위로 회전체를 설치하여 재활용 페트병의 분쇄된 페트 플레이크에 묻어 있는 이물질이나 지저분한 때를 세척액으로 교반하여 제거하고 이후 아래로 가라앉는 페트 플레이크는 밑에서부터 순차적으로 상기 상승스크류를 타고 다음 공정의 침전조를 거쳐 배출되도록 하여 세척효율이 향상된 상승스크류를 이용한 연속식 세척장치에 관한 것이다.The present invention relates to a continuous washing apparatus using a rising screw, and more particularly, to install a rotary body around a rising screw vertically installed in the center of the washing tank to remove foreign substances or grime from the crushed PET flakes of a recycled PET bottle. The pet flakes which are removed by stirring with a washing liquid and then sink down are related to the continuous washing apparatus using the rising screws, which are sequentially discharged from the bottom, are discharged through the settling tank of the next process.

일반적으로 폐 페트병을 분쇄한 페트 플레이크(PET Flake)의 세척방법은 하단부에 수평으로 횡단하는 스크류를 설치하거나 측면에 일정한 각도로 기울어진 스크류를 설치한 대형 세척조에 물이나 세척액을 채우고 페트 플레이크를 투입하여 물이나 세척액을 통과하여 하부쪽으로 떨어진 페트 플레이크를 회전구동부에 의해 가동되는 스크류를 이용하여 후공정으로 배출하는 방식으로써, 이때 회전체를 이용한 교반작용을 실시하여 세척액의 와류에 의해 페트 플레이크 표면의 이물질을 제거하고, 세척액의 농도와 온도를 조절하여 침착되어 있는 더러운 때를 시간경과에 의해 세척하는 것이다.In general, the method of washing PET flakes in which waste PET bottles are crushed is filled with water or washing liquid in a large washing tank having a horizontally-crossed screw at the bottom or a screw inclined at an angle. The flakes dropped to the lower side through water or washing liquid are discharged to the post process by using the screw operated by the rotary driving unit.At this time, the stirring process using the rotating body is performed to vortex the surface of the pet flakes by the vortex of the washing liquid. It removes foreign substances, and controls the concentration and temperature of the cleaning liquid to wash the dirty dirt deposited over time.

그러나 세척조의 하부로 떨어진 페트 플레이크는 가동되고 있는 스크류에 의해 곧바로 후공정으로 배출되어지기 때문에 페트 플레이크가 세척액속에 머무르는 시간이 적고 세척액의 농도와 온도를 지속적으로 일정하게 유지하지 못할 경우 세척상태가 저하되는 문제가 발생된다.However, since the pet flakes falling to the bottom of the washing tank are discharged immediately to the post process by the operating screw, the washing condition decreases when the pet flakes stay in the washing liquid for a short time and the concentration and temperature of the washing liquid cannot be kept constant. Problem occurs.

폐 폐트병 재활용공장의 세척과정은 다수개의 세척조를 설치하고 세척조의 하단부에 원료를 배출하기 위하여 이송용 스크류를 45°~ 60°정도의 각도로 부착하여 배출하고 있는데 이 경우 투입된 원료는 하단의 이송스크류에 쌓이게 되면 세척조에 침지되는 시간 없이 이송스크류에 의해 바로 후공정으로 이송됨에 따라 세척시간이 부족하여 다수개의 세척조를 설치하여야 하고, 페트 플레이크의 표면에 묻어서 배출되는 세척액이 많기 때문에 계속적인 세척액 공급이 필요하며, 후공정에서 세척액을 제거하기 위해 깨끗한 용수가 대량으로 투입되어야 하며, 최종제품에서 세척액의 잔존이나 세척부족으로 인한 품질저하가 발생되는 문제가 있었다.Waste washing process of waste bottle recycling plant installs a plurality of washing tanks and attaches the screw for feeding at the angle of 45 ° ~ 60 ° to discharge the raw material at the lower part of the washing tank. When accumulated on the screw, it is transferred to the post process immediately by the transfer screw without being immersed in the washing tank. Therefore, the washing time is insufficient. Therefore, a plurality of washing tanks must be installed. This is necessary, clean water must be added in a large amount to remove the cleaning solution in the post-process, there was a problem that the quality degradation due to the remaining or lack of cleaning solution in the final product.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 투입된 페트 플레이크가 세척조 내부의 회전체에 의해 세척액과 교반 된 후, 세척조 하부에 침전되어 이송가능한 부피의 페트 플레이크가 모여진 후 수직으로 설치되어진 상승스크류에 의해 후공정으로 이송됨으로써, 페트 플레이크가 일정시간 이상 세척액 속에 침지되어 페트 플레이크 표면의 이물질이나 더러운 때가 제거되며 재 활용 제품의 품질이 향상되고 세척액의 과다한 사용을 줄인 상승스크류를 이용한 연속식 세척장치를 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is to vertically after the injected pet flakes are stirred with the washing liquid by the rotating body inside the washing tank, and the PET flakes of the transportable volume are collected at the bottom of the washing tank. As the conveying screw is transferred to the post process by the rising screw installed in the process, the PET flakes are immersed in the washing liquid for more than a certain time to remove foreign substances or dirt on the surface of the PET flakes.The rising screw improves the quality of recycled products and reduces the excessive use of the washing liquid.

이처럼 구성된 본 발명의 투입된 페트 플레이크 세척 과정은 다음과 같다.The injected pet flake washing process of the present invention configured as described above is as follows.

폐 페트병이 분쇄기에 의해 5~10mm로 분쇄된 페트 플레이크가 세척조(1)에 투입되면 회전모터(5)로 구동되는 회전체(3)에 의해 생성된 세척액의 와류가 페트 플레이크 표면의 이물질을 제거하고 세척액을 페트 플레이크에 충분히 적셔준다. 세척과정에서 세척조(1) 하부로 떨어진 페트 플레이크는 수직으로 설치된 상승스크류(2)의 하단부 주위로 모여지게 된다. 상기 상승스크류(2)는 세척조(1)의 하단부에서 격판(4)까지 외경이 점차적으로 커졌다가 격판(4)을 통과하여 스크류배관(12)으로 들어가면서 감소되는 형태를 갖는 것으로서, 수직형태의 상승스크류(2)가 페트 플레이크의 이송을 원활히 할 수 있도록 구성되며, 세척조(1) 하부로부터 모여진 페트 플레이크는 후공정으로 이송이 가능하게 되므로 상승스크류(2)의 회전 속도와 페트 플레이크의 투입량을 원하는 조건으로 조절한다면 페트 플레이크를 세척액 속에 정체시키는 시간 및 생산량 조절도 가능하다.When the waste PET bottle is crushed to 5 ~ 10mm by the pulverizer is put into the washing tank (1), the vortex of the washing liquid generated by the rotating body (3) driven by the rotary motor (5) removes foreign substances on the surface of the pet flakes And soak the cleaning solution in the pet flakes. During the washing process, the pet flakes dropped to the lower part of the washing tank 1 are collected around the lower end of the rising screw 2 installed vertically. The rising screw (2) has a form in which the outer diameter gradually increases from the lower end of the washing tank (1) to the diaphragm (4) and then decreases as it enters the screw pipe (12) through the diaphragm (4), and the vertical rise The screw (2) is configured to facilitate the transfer of the pet flakes, and the pet flakes collected from the bottom of the washing tank (1) can be transferred to the post-process, so that the rotational speed of the lifting screw (2) and the amount of the pet flakes desired Conditions can also be used to control the amount of time and yield of the pet flakes in the wash solution.

좀 더 많은 양을 세척하고자 할 경우 세척조(1)를 다수개 설치하면 된다. 또한 세척액 속에 보다 많은 시간을 침지시킬 수 있음으로 인하여 세척력이 더욱 향상되어 고품질의 제품생산이 가능하다. 침전조(11)는 세척조(1)의 스크류배관(12) 상부와 원료 이송로(8)로 연결되는데, 상승스크류(2a)의 회전속도를 고속이나 저속 으로 조절하여 침전조(11)내에 페트 플레이크의 정체되는 양을 조절함으로서, 세척과정 중 발생될 수 있는 공정중 부하를 해소하는 역할을 한다. 도 2에서 스크류배관(12)의 하단부에 연결된 격판(4)은 나중에 떨어지는 페트 플레이크가 상승스크류(2)에 의해 먼저 이송되는 것을 방지하여 밑에서 부터 순차적으로 페트 플레이크가 후공정으로 이송되도록 하며, 상승스크류(2)로 이송되는 페트 플레이크가 회전체(3)에 의한 세척액의 와류에 영향을 받지 않고 이송되도록 해준다.If you want to wash more, you can install a plurality of washing tank (1).
