The production cost and the price of the vacuum extruder are very expensive, and if the body is hard, the extrusion is not done well from the mold, so the hole of the mold is clogged or high heat and defects occur due to the excessive load of the extrusion pump.

Description

슬립 캐스팅 세라믹 하니컴 제조장치Slip Casting Ceramic Honeycomb Manufacturing Equipment

따라서, 본 발명은 가솔린·디젤· LPG·LNG 와 같은 화석연료를 사용하는 자동차·쓰레기 소각로·화력발전소·디젤기관차·선박 각종 보일러 및 난방용 난로등의 배기가스에 포함된 NOx,SOx, CO·미반응 탄화수소(HC) 등 유해 물질들을 분해 정화시키는 촉매 하니컴 담체를 제조하는 장치에 관한 것이다.Accordingly, the present invention provides NO x , SO x , CO contained in exhaust gases such as automobiles, garbage incinerators, thermal power plants, diesel locomotives, various boilers and heating stoves using fossil fuels such as gasoline, diesel, LPG, and LNG. A device for producing a catalytic honeycomb carrier for decomposing and purifying hazardous substances such as unreacted hydrocarbons (HC).

현재까지의 하니컴 담체는 압축 성형용 금형 진공 압출기에 부착시켜 제작하고 있으나 압출 성형할 때 금형으로부터 소지가 부드럽게 빠져나와 원하는 형상을 유지하도록 하는 방법은 첨가제의 종류와 그 양에 의존하도록 되어 있어서 금형 제작비와 진공압출기의 가격이 매우 비싸 생산성이 떨어지는 편이다.Until now, honeycomb carriers have been manufactured by attaching them to a mold vacuum extruder for compression molding. However, the method of making the body smoothly escape from the mold to maintain the desired shape during extrusion molding depends on the type and amount of additives. And the cost of the vacuum extruder is very expensive, the productivity is low.

이때 소지가 딱딱할 경우 금형으로부터 압출이 잘 이루어지지 않아 금형의 구멍이 막히거나 압출펌프의 부하 증가로 고열 및 불량이 발생된다.At this time, if the body is hard, extrusion is not performed well from the mold, so the hole of the mold is clogged or high load and defect are caused by an increase in load of the extrusion pump.

또한, 소지가 너무 부드러우면 압출 후 원하는 형상을 유지하지 못하고 하니컴 담체는 붕괴되고 만다.Also, if the body is too soft, the honeycomb carrier may collapse while not retaining the desired shape after extrusion.

이와 같은 진공 압출식 하니컴 담체 제작은 소지 제조의 어려움이 따르고 그에 따른 불량율이 비교적 높은 편이다.The manufacture of such a vacuum extruded honeycomb carrier is difficult to produce the base material, the defect rate is relatively high.

본 발명에서는 석고로 만든 주형에 하니컴 담체 제조용 소지액(소지 수용액)을 부어넣어 하니컴 담체를 주조하는 슬립 캐스팅(slip-casting) 하니컴 담체 제조 장치를 발명함에 목적이 있다.An object of the present invention is to invent a slip-casting honeycomb carrier manufacturing apparatus for casting a honeycomb carrier by pouring a holding solution (aqueous solution of honeycomb) for producing a honeycomb carrier into a mold made of gypsum.

지금부터 이와 같은 방법으로 제조된 하니컴은 앞서 언급한 진공 압출식 하니컴과 구별되게 슬립 캐스팅 하니컴으로 부르기로 한다.The honeycomb manufactured in this way from now on will be referred to as slip casting honeycomb to be distinguished from the aforementioned vacuum extruded honeycomb.

슬립 캐스팅 하니컴 제작은 진공 압출 하니컴 제작보다 하니컴 담체 소지제조가 비교적 쉽고 불량율이 적을 뿐 아니라 다양한 형상의 세라믹 하니컴 담체를 비교적 저렴한 가격으로 만들 수 있는 장점을 가지고 있다.Slip-casting honeycomb fabrication has the advantage that it is relatively easy to manufacture a honeycomb carrier and produces a lower defect rate than a vacuum extrusion honeycomb fabrication, and that ceramic honeycomb carriers of various shapes can be made at a relatively low price.

자동차 및 공장 배기가스 정화처리에는 백금(Pt), 팔라듐(Pd)과 로듐(Rh) 같은 귀금속 촉매가 사용되고 있으나, 이와 같은 귀금속 촉매는 단가가 높고 가격이 비싸기 때문에 대체 촉매 개발이 활발히 진행되고 있다.Precious metal catalysts such as platinum (Pt), palladium (Pd) and rhodium (Rh) are used for the exhaust gas purification treatment of automobiles and factories, but alternative catalysts are actively being developed due to the high cost and high price of these precious metal catalysts.

특히, 퍼로브스카이트(perovskit) 촉매는 열 안정성이 뛰어나고 산화활성이 우수하여 완전연소 반응에서 귀금속 촉매에 필적하는 성능을 나타내면서도 가격이 저렴하기 때문에 많은 연구가 수행되고 있다.In particular, many studies have been carried out because perovskit catalysts have excellent thermal stability and excellent oxidation activity, which are comparable to noble metal catalysts in a complete combustion reaction, and are inexpensive.

순수 촉매의 제조보다는 산업화에 적용이 편리한 감마-알루미나 (T-A1203), 바륨-알루미나(Ba-A1203) 및 코디어라이트(cordierite)로 만든 하니컴 담체에 퍼로브스카이트(Perovskite, ABO3)를 담지시킨 담지 촉매 제조에 관심이 집중되고 있다.Perovskite is used in honeycomb carriers made of gamma-alumina (T-A1 2 0 3 ), barium-alumina (Ba-A1 2 0 3 ), and cordierite, which are more convenient for industrialization than the preparation of pure catalysts. Attention is focused on the production of supported catalysts supported on Perovskite, ABO 3 ).

따라서, 본 발명에서는 앞서 언급한 감마-알루미나(T-A1203)와 코디어라이트(cordierite, 2MgO·2A1205·5Si02)로 담체 하니컴을 만드는 장치 제작에 초점을 두기로 한다.Therefore, the present invention focuses on the production of a device for making a carrier honeycomb from the aforementioned gamma-alumina (T-A1203) and cordierite (cordierite, 2MgO · 2A1 2 0 5 · 5Si0 2 ).

상기목적을 달성하기 위하여 성형실을 갖는 석고주형의 개구부에 플렌지가 빙둘러 형성된 상부판과 하부판을 각각 형성하고, 상·하부판의 플렌지 부분에 수직 지지간을 등 간격으로 설치하여 상부판을 분리할 수 있도록 하고, 상부판과 하부판의 상·하부에 돌출부와 요입부를 각각 형성하고, 석고주형과 플렌지 사이에 패킹을 설치하고, 요입부의 상부에 깔대기 형상의 호퍼를 설치하고, 요입부의 가장자리 부분에 성형실과 연결되는 주입공과 배기관을 복수 개 설치하거나 형성하고, 돌출부에 조밀한 간격으로 삽입공을 형성한 다음 철금속을 인발 가공하여 길이가 긴 성형봉의 상단부를 평방 인치당 약 100-500셀(100-500CellS/inCh2)의 조밀한 간격을 갖도록 삽입 고정하여 성형봉과 성형봉 사이에 하나로 연결되는 좁은 간격의 공간부가 형성되도록 하고, 하부판에 삽입공을 형성하여 성형봉의 하단부가 주조를 전·후하여 삽입 및 분리되게 하고, 하부판의 요입부에 영구자석이나 전자석을 매입 설치하여 주조할 때 철금속으로 된 성형봉(54)의 하단부가 자력에 의해 그 간격들이 유지되게 한 것으로, 이하 본 발명의 바람직한 실시 예를 첨부한 도면에 따라 상세히 설명하면 다음과 같다.In order to achieve the above object, the upper plate and the lower plate each having a flange formed in the opening of the gypsum mold having the molding chamber are respectively formed, and the upper plate can be separated by equally spaced vertical supports between the flange portions of the upper and lower plates. The protrusions and the recesses are formed at the upper and lower portions of the upper plate and the lower plate, and a packing is installed between the gypsum mold and the flange, and a funnel-shaped hopper is installed at the upper portion of the recess. Install or form a plurality of injection holes and exhaust pipes connected to the seal, and form insertion holes at tight intervals on the protrusions, and then draw the ferrous metal to process the upper end of the long forming rod at about 100-500 cells per square inch (100-500CellS). / inCh 2 ) to have a tight gap between the forming rod and the forming rod to form a narrow spaced part connected to one, Insertion holes are formed in the lower plate so that the lower end of the forming rod can be inserted and separated by casting before and after casting, and the lower end of the forming rod 54 made of ferrous metal when the permanent magnet or electromagnet is inserted into the recess of the lower plate and cast. The intervals are maintained by the magnetic force, which will be described below in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

상기 석고주형(10)은 세라믹 소지 수용액(12)을 부어 넣게되면 모세관 현상에 의해 소지 수용액(12) 중의 수분을 흡수한 다음 석고주형(10)의 바깥으로 내뿜게 되며, 석고주형(10)의 형상은 성형하고자 하는 세라믹 하니컴(14)의 형상에 따라 원통형·정사각형·직사각형·타원형 또는 다각형 등으로 각각 형성할 수 있으며, 석고주형(10)의 상·하부에 형성된 개구부(2)(4)에는 플렌지(18)(20)가 빙둘러 형성된 상부판(22)과 하부판(24)을 각각 형성하고, 상·하부판(22)(24)의 플렌지(18)(20) 부분에는 제2도와 같이 상·하부판(22)(24)을 잡아주는 3개 내지 6개의 지지간(26)을 등 간격으로 설치하여 세라믹 하니컴(14)이 성형되는 동안 석고주형(10)이 견고히 고정되게 한다.When the gypsum mold 10 is poured into the ceramic holding solution 12, the gypsum mold 10 absorbs the moisture in the holding solution 12 by capillary action and then blows out of the gypsum mold 10.

Ceramic honeycomb can be produced.

상기에서 전자석(64)으로 구성하는 경우 스위치(SW)와 구동전원(I)이 전자석(64)과 직렬로 접속되며, 탈형할 때 스위치(SW)를 오프(OFF)시키면 전자석(64)의 자력과 성형봉(54) 흡자력이 곧바로 제7되므로 쉽게 탈형할 수 있게 된다.In the case of the electromagnet 64, the switch SW and the driving power supply I are connected in series with the electromagnet 64. When the switch SW is turned off when demolding, the magnetic force of the electromagnet 64 is reduced. And the forming rod 54 can be easily demolded because the absorption force is immediately seventh.

제9도는 본 발명 일 실시 예로 도시한 평면도로, 스위치(SW)와 구동전원(I)이 직렬로 접속되고 평면적이 비교적 널은 평판형의 전자석(66)위에 복수 개의 세라믹 하니컴(1)을 얹어 설치한 다음 세라믹 하니컴(12)을 제작할 수 있음을 도시하고 있으며, 한 개의 전자석(66)을 이용하여 각각의 세라믹 하니컴 제조장치(1)에 설치된 성형봉(54)의 하단부를 자력으로 동시에 고정시킬 수 있는 효과가 있다.FIG. 9 is a plan view showing an embodiment of the present invention, in which a plurality of ceramic honeycombs 1 are placed on a flat electromagnet 66 in which a switch SW and a driving power source I are connected in series and whose planes are relatively large. After installation, it is shown that the ceramic honeycomb 12 can be manufactured, and by using one electromagnet 66, the lower ends of the forming rods 54 installed in each ceramic honeycomb manufacturing apparatus 1 can be simultaneously fixed by magnetic force. It can be effective.
