Abstract

The present invention relates to a device for collecting the metal powder of a waste friction material generated when the friction material of a brake pad for an automobile is processed. When a magnet feeder (12) supplies a waste friction material in a supply container (10) to a vibrating screen (14), while the waste friction material is transported along the vibrating screen (14), a light general waste friction material or the metal powder of particles is scattered by the hot air of an air supply fan (16) and a heater (18), and the metal powder of particles heavier than the general waste friction material is collected in a first cyclone dust collector (26). In addition, the light general waste friction material passes through the first cyclone dust collector (26) and is collected in a second cyclone dust collector (28). Heavy metal powder is dropped and discharged along a discharge pipe (20) provided at the bottom of the vibrating screen (14) by the weight thereof. Therefore, the metal powder of a copper component can be recovered from the waste friction material.

Description

자동차용 브레이크패드의 마찰재가공시 발생된 폐마찰재의 금속분 회수장치{Metal powder collecting device of waste friction materials when friction materials on brake pads for automobiles are made available}Metal powder collecting device of waste friction materials when friction materials on brake pads for automobiles are made available}

본 발명은 자동차용 브레이크패드의 제조시 마찰재의 표면가공과 면취가공 및 슬로트가공시 발생된 폐마찰재로부터 구리성분의 금속분을 회수하기 위한 금속분 회수장치에 관한 것이다.The present invention relates to a metal powder recovery device for recovering copper-based metal powder from waste friction material generated during surface processing, chamfering, and slot processing of a friction material when manufacturing a brake pad for an automobile.

일반적으로 자동차용 브레이크패드의 마찰재는 크게 원재료를 결합하여 형태를 갖추도록 하기 위한 결합재와 마찰재의 강도와 성형성 등을 부여하기 위한 보강재 및 마찰성능을 부여하기 위한 마찰조정재로 이루어지고 또 여기에 내페이드성과 내마모성을 부여해주기 위한 구리성분의 금속분을 첨가해주도록 하고 있는데, 마찰재에 구리성분의 금속분이 포함될 경우 매 제동시 마모에 의한 구리성분의 금속분 배출로 환경을 크게 오염시키게 되고 또 이러한 이유로 일부 선진국가에서는 구리성분의 금속분을 일정량 이상 함유하고 있는 브레이크패드는 사용을 금지하는 등 구리성분의 금속분에 의한 환경오염을 심각하게 여기고 있다.In general, the friction material of brake pads for automobiles is largely composed of a binder for combining raw materials to form a shape, a reinforcing material for imparting strength and formability of the friction material, and a friction adjusting material for imparting friction performance. Copper-based metal powder is added to provide fading and abrasion resistance.If copper-based metal powder is included in the friction material, the environment is greatly polluted by the discharge of copper-based metal powder due to wear during each braking process.For this reason, some advanced countries , Considers serious environmental pollution caused by copper-based metal powders, such as prohibiting the use of brake pads containing more than a certain amount of copper-based metal powder.

그러나 자동차용 브레이크패드는 등록특허 10-1573313호 '브레이크 패드 마찰재 연속 가공장치' 및 등록특허 10-1866166호 '진공흡입 유닛을 갖는 브레이크 디스크 패드 마찰재 연삭장치' 등과 같이 백플레이트 일면에 분말화된 원재료를 열가압하여 마찰재를 성형한 후 규격화를 위해 그 표면을 황삭 및 정삭가공해 주어야 하고 또 양측에는 디스크에 대한 마찰재의 접촉면적을 줄여서 균일한 면압을 부여해주기 위한 면취가공을 해 주어야 하며, 중앙부에는 마찰소음감소 및 마모시 분진배출을 위한 슬로트가공을 해주어야 하므로 이러한 마찰재의 성형후 연삭기를 이용한 연삭가공시 발생되는 폐마찰재 내 금속분으로 인한 환경오염도 심각한 실정이라 이에 대한 대책도 시급한 실정이다.However, automotive brake pads are raw materials powdered on one side of the back plate, such as Registration Patent No. 10-1573313'Brake Pad Friction Material Continuous Processing Device' and Registration Patent No. 10-1866166'Brake Disc Pad Friction Material Grinding Device with Vacuum Suction Unit'. After the friction material is formed by thermally pressurizing the friction material, the surface should be roughed and finished for standardization, and chamfering should be applied to both sides to provide a uniform surface pressure by reducing the contact area of the friction material to the disk. Since it is necessary to perform slot processing to reduce friction noise and discharge dust during wear, environmental pollution due to metals in the waste friction material generated during grinding using a grinding machine after forming such friction material is also a serious situation.Therefore, countermeasures are urgently needed.

The first cyclone dust collector 26 and the second cyclone dust collector 28 are connected and installed side by side using pipes 22 and 24.

본 발명은 브레이크패드의 성형후 마찰재의 표면가공과 면취가공 및 슬로트가공과정에서 발생되는 폐마찰재를 공급통(10)에 공급해주게 되면 공급통(10) 내 폐마찰재가 마그넷피더(12)에 의해 전방으로 이송되어 케이스 내에 경사지게 설치된 바이브레이팅 스크린(14) 상에 공급되게 하고, 바이브레이팅 스크린(14) 상에 공급된 폐마찰재는 진동모터의 진동 및 경사면에 의해 바이브레이팅 스크린(14)을 따라 전방으로 이송되면서 구리 등 금속분이 분리제거되게 한다.In the present invention, when the waste friction material generated in the process of surface processing, chamfering, and slot processing of the friction material after forming the brake pad is supplied to the supply container 10, the waste friction material in the supply container 10 is transferred to the magnet feeder 12. The waste friction material supplied on the vibrating screen 14 is transferred to the front by the vibrating screen 14, which is installed inclined in the case, along the vibrating screen 14 by the vibration and inclined surface of the vibrating motor. As it is transferred to the front, metals such as copper are separated and removed.

즉, 폐마찰재가 바이브레이팅 스크린(14)을 따라 이송될 시 그 측면에 차례로 연결된 히터(16)와 급기팬(18)은 열풍을 발생시켜서 바이브레이팅 스크린(14) 내부로 공급해주게 되므로 바이브레이팅 스크린(14) 내 폐마찰재는 열풍에 의한 건조로 뭉침 없이 분말상태를 유지하도록 하면서 이송시 가벼운 일반폐마찰재와 미립자화된 금속분은 열풍에 의해 비산하여 이송관(22)(24)을 따라 제1사이클론집진기(26)로 이송되는데, 이때 일반폐마찰재에 비해 무거운 미립자화된 금속분은 제1사이클론집진기(26)에 집진되고 또 가벼운 일반폐마찰재는 제1사이클론집진기(26)로부터 제2사이클론집진기(28)로 이송되어 제2사이클론집진기(28)에 집진되며, 무거운 금속분은 열풍에도 불구하고 자중에 의해 바이브레이팅 스크린(14) 저부의 배출관(20)을 따라 낙하배출되어 별도의 수집통에 수집된다.That is, when the waste friction material is transferred along the vibrating screen 14, the heater 16 and the air supply fan 18, which are sequentially connected to the side, generate hot air and supply it to the inside of the vibrating screen 14, so the vibrating screen (14) The inner waste friction material is dried by hot air to maintain the powder state without agglomeration, while the light general waste friction material and particulated metal powder are scattered by the hot air and the first cyclone along the transfer pipes (22, 24). It is transferred to the dust collector 26, at this time, the particulated metal, which is heavier than the general waste friction material, is collected in the first cyclone dust collector 26, and the light general waste friction material is transferred from the first cyclone dust collector 26 to the second cyclone dust collector 28. ) Is transferred to the second cyclone dust collector 28 and collected in the second cyclone dust collector 28, and the heavy metal powder falls along the discharge pipe 20 at the bottom of the vibrating screen 14 by its own weight despite the hot air and is collected in a separate collection container.

따라서 바이브레이팅 스크린(14)의 배출관(20)을 통하여 배출된 구리성분의 금속분 및 제1사이클론집진기(26)에 집진된 구리성분의 금속분은 다른 용도로 재활용하면 되므로 산업페기물의 발생량을 최소화하면서 구리성분의 금속분으로 인한 환경오염을 방지해줄 수가 있게 된다.Therefore, the copper-based metal powder discharged through the discharge pipe 20 of the vibrating screen 14 and the copper-based metal powder collected in the first cyclone dust collector 26 can be recycled for other purposes. It is possible to prevent environmental pollution due to the metal powder of the component.
