Description
본 고안은 압출기의 압출원료중 불순물 제거장치에 관한 것으로, 더욱 상세하게는 압출기에서 압출되는 원료중에 함유되어 있는 모래 등과 같은 불순물을 걸러주는 불순물제거판을 일정 주기로 교체 청소하여 사용할 수 있도록 하여 불순물제거판의 교체과정에 있어서도 연속하여 원료로 공급하고 불순물제거판의 막힘으로 인한 압출기의 과부하를 방지할 수 있도록 함을 목적으로 한 것이다.The present invention relates to an impurity removal device in the extruded raw material of the extruder, and more particularly, to remove impurities by allowing the impurity removal plate that filters impurities such as sand contained in the raw material extruded from the extruder to be used at regular intervals. In the process of replacing the plate is to continuously supply the raw material and to prevent the overload of the extruder due to clogging of the impurity removal plate.
일반적으로, 압출기는 입자상태의 원료를 가열 용융하여 압출시키는 것으로, 입자상태로 투입되는 원료중에는 모래 등과 같은 불순물이 함유되어 있어, 이를 제거하지 않을 경우에는 압출물의 균열 또는 기공 형성을 초래하므로 이를 제거하기 위하여 압출노즐과 압출기 사이에 불순물을 제거할 수 있도록 한 불순물제거판을 구비하고 있다.In general, the extruder is a heat-melting extrusion of the raw material in the particulate state, and the raw material introduced in the particulate state contains impurities such as sand, and if not removed, it causes cracking or pore formation of the extrudate and thus is removed. In order to remove impurities, an impurity removal plate is provided between the extrusion nozzle and the extruder.
그러나, 종래의 불순물제거판은 압출기와 노즐 사이에 고정 결착되어 있는 것으로, 일정시간 사용하게 되면 불순물이 누적되어서 막혀 원활한 압출물의 공급이 이루어지지 않고 압출기에 과부하가 발생하므로 압출기의 작동을 정지하고 불순물제거판을 교체하여야 하는 불편함이 있었다.However, the conventional impurity removal plate is fixedly fixed between the extruder and the nozzle, and when used for a certain time, impurities accumulate and become clogged, so that the extruder is not supplied smoothly, and the extruder is overloaded so that the extruder stops the operation There was an inconvenience to replace the removal plate.
또한, 불순물제거판의 교체과정에 있어 압출기가 냉각되어 용융된 원료를 사용할 수 없고 압출기를 청소하여야하는 등 작업효율이 저하되는 등의 문제점이 있었다.In addition, in the replacement process of the impurity removal plate, there is a problem that the working efficiency is reduced such that the extruder is cooled and the molten raw material cannot be used and the extruder needs to be cleaned.
이에, 본 고안은 상술한 문제점을 해결하기 위하여 안출한 것으로, 일정 주기로 불순물제거판을 교체 청소하여 불순물의 퇴적으로 인한 압출기의 작동 정지 등을 방지할 수 있도록 한 것이다.In order to solve the above problems, the present invention is designed to prevent the operation of the extruder due to the deposition of impurities by replacing and cleaning the impurity removal plate at regular intervals.

본 고안은 일정주기로 불순물을 걸러주는 불순물제거판을 교체 청소하여 연속적인 압출작업을 실시함과 더불어 불순물제거판의 교체로 인한 원료의 낭비를 방지할 수 있도록 한 것으로, 압출기와 압출노즐 사이에 구비되며 측면으로 관통되는 제거판결합구(11)를 형성한 불순물제거부(10)와, 상기 불순물제거부(10)의 제거판결합구(11)에 슬라이딩 결합되며 두 개 이상의 필터부를 구비한 불순물제거판(20)과, 상기 불순물제거판(20)의 가열을 위하여 끼워 결합되는 히터(25)와, 상기 불순물제거판(20)을 슬라이딩 이동시키는 액츄에이터(30)로 구성된 것이다.The present invention is designed to prevent the waste of raw materials due to replacement of the impurity removal plate by replacing and cleaning the impurity removal plate that filters the impurities at regular intervals, and is provided between the extruder and the extrusion nozzle. And impurity removal part 10 having a removal plate coupling hole 11 penetrating to the side, and an impurity having two or more filter parts and slidingly coupled to the removal plate coupling hole 11 of the impurity removal part 10. The removal plate 20, the heater 25 is inserted and coupled for heating the impurity removal plate 20, and the actuator 30 for slidingly moving the impurity removal plate 20.
여기서, 상기 불순물제거판(20)의 필터부는 다수의 구멍이 천공 형성된 판체로만 이루어진 걸름판(22)과 다수의 구멍이 천공 형성되며 양측에 끼움돌기(24a)를 돌출형성한 걸름지지판(24)과 다수의 미세한 구멍이 형성되며 상기 걸름판(22)과 걸름지지판(24) 사이에 개재되는 필터판(23)으로 이루어진 필터체와, 상기 필터체가 결합되게 관통 형성되며 내측에 걸름판(22)이 안착되어 걸려지는 걸림턱(21a)을 형성하고, 외측에 걸름지지판(24)의 끼움돌기(24a)가 결합되는 끼움공(21b)을 형성한 필터체결합구(21)로 구성된 것이다.Here, the filter part of the impurity removal plate 20 is a filter plate 22 made of only a plate body formed with a plurality of holes and a plurality of holes formed therein, and the filter support plate 24 protruding the fitting protrusions 24a on both sides thereof. ) And a plurality of fine holes are formed, the filter body consisting of a filter plate 23 interposed between the filter plate 22 and the filter support plate 24, and formed through the filter body to be coupled to the filter plate 22 inside. ) Is formed of a catching jaw (21a) is settled to be caught, the filter body coupling sphere 21 formed a fitting hole (21b) is coupled to the fitting projection (24a) of the filter support plate 24 on the outside.
한편, 상기 걸름판(22)과 걸름지지판(24)은 그 구멍이 중앙으로 갈 수록 작아지게 형성하는 것이 바람직하며, 원료의 진행 방향에 대하여 걸름판(22)이 앞쪽에 형성되게 하고, 걸름지지판(24)의 구멍보다 걸름판(22)의 구멍을 작게 형성하는 것이 바람직하다.On the other hand, the filter plate 22 and the filter support plate 24 is preferably formed to be smaller as the hole toward the center, so that the filter plate 22 is formed in the forward direction with respect to the direction of the raw material, the filter support plate It is preferable to form the hole of the filter plate 22 smaller than the hole of (24).
그리고, 상기 불순물제거판(20)을 슬라이딩 이동시키는 액츄에이터(30)는 불순물제거판(20)을 1 초 이내로 순간 교체할 수 있게 포웨이밸브(50)를 통하여 어큐뮬레이터(40)에 축적된 유압에너지를 공급받아 동작되게 구성한 것으로, 상기 불순물제거판(20)의 교체시간을 최소화하여 압출이 연속적으로 이루어질 수 있게 한 것이다.In addition, the actuator 30 slidingly moving the impurity removing plate 20 may accumulate hydraulic pressure accumulated in the accumulator 40 through the four-way valve 50 so that the impurity removing plate 20 may be instantly replaced within 1 second. It is configured to operate by supplying, minimizing the replacement time of the impurity removal plate 20 is to be made to extrusion continuously.
한편, 상기 어큐뮬레이터(40)는 모터(70)에 의하여 구동되는 유압펌프(60)로부터 작동유를 공급받아 유압에너지를 축적하는 것으로, 상기 어큐뮬레이터(40)의 압력이 일정 압력 이상이 되면 관로상의 압력감지기(80)기 이를 감지하여 모터(70)의 동작을 정지시켜 과부하로 인하 모터의 손상을 방지할 수 있게 하는 것이다.Meanwhile, the accumulator 40 receives hydraulic oil from the hydraulic pump 60 driven by the motor 70 and accumulates hydraulic energy. When the pressure of the accumulator 40 becomes higher than or equal to a predetermined pressure, the pressure sensor on the pipe line is detected. 80 is to detect this to stop the operation of the motor 70 to prevent damage to the motor due to overload.
이하, 본 고안의 작동과정에 대하여 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.
상기한 바와 같이 압출노즐과 압출기 사이에 두 개 이상의 필터부를 구비한 불순물제거판(20)이 슬라이딩 결합되어 있는 불순물제거부(10)로 이루어진 본 고안은 압출기에 원료를 공급하여 압출 성형하는 과정에 있어 원료중에 함유되어 있는 불순물은 일차적으로 걸름지지판(24)에 의하여 걸러지고, 이차 적으로 다수의 미세한 구멍이 형성된 필터판(23)에 의하여 걸러지게 된다.As described above, the present invention consists of an impurity removal unit 10 in which an impurity removal plate 20 having two or more filter units is slidingly coupled between the extrusion nozzle and the extruder. The impurities contained in the raw material are first filtered by the filtering support plate 24 and secondly by the filter plate 23 in which a plurality of fine holes are formed.
이상과 같이 이 단계로 불순물이 걸러진 원료에 의하여 성형된 압출물은 균열과 기공 등이 발생하지 않는 우수한 제품이 되는 것이다.As described above, the extrudate molded by the raw material filtered out of the impurity is an excellent product without cracks and pores.
한편, 상기한 바와 같은 압출과정에 있어 필터부를 교체하고자 할 경우에는 포웨이밸브(50)를 작동시켜 어큐뮬레이터(40)에 축적된 유압에너지를 액츄에이터(30)로 공급하여 상기 액츄에이터(30)가 어큐뮬레이터(40)에 축적된 유압에너지에 의하여 순간 동작되어 불순물제거판(20)을 슬라이딩 이동시켜 불순물이 퇴적된 필터부는 외부로 노출시키고 깨끗한 필터부가 압출물이 유동되는 관로상에 위치되게 하므로 원료의 공급이 연속하여 이루어지게 된다.On the other hand, when the filter unit is to be replaced in the extrusion process as described above, by operating the four-way valve 50 to supply the hydraulic energy accumulated in the accumulator 40 to the actuator 30 to the actuator 30 accumulator Instantaneous operation is performed by the hydraulic energy accumulated in the 40 to slide the impurity removal plate 20 so that the impurity accumulated filter part is exposed to the outside and the clean filter part is positioned on the pipeline through which the extrudate flows. This is done continuously.
그리고, 불순물이 퇴적되어 막힌 필터부는 걸름지지판(24)을 제거하고 필터판(23)과 걸름판(22)을 꺼내어 에어 등으로 불순물을 제거하고 다시 필터체결합구(21)에 장착한다.Then, the filter portion clogged with impurities are removed, the filter support plate 24 is removed, the filter plate 23 and the filter plate 22 are taken out, and impurities are removed by air or the like, and then the filter unit coupling port 21 is mounted.
이상과 같이 불순물이 퇴적되어 막힌 필터체를 청소하여서 준비하므로서 연속하여 압출이 이루어지는 것이다.As described above, extrusion is continuously performed by cleaning and preparing a filter body in which impurities are deposited and clogged.
따라서, 본 고안은 압출과정에 있어 불순물제거판을 교체 청소하여 주므로서 원료의 공급을 불순물제거판의 교체와 관계없이 연속적으로 실시할 수 있으므로 작업성이 향상되며, 필터부의 필터체를 분해하여 청소할 수 있게 하므로서 필터체의 청소가 용이한 매우 유용한 것이다.Therefore, the present invention improves workability because the raw material can be continuously supplied regardless of replacement of the impurity removal plate by replacing and cleaning the impurity removal plate during the extrusion process. It is very useful to make it easy to clean the filter body.
