본 발명은 유리연마 슬러지를 사용한 경량소재 제조용 로터리형 킬른에 관한 것으로서 보다 상세하게는 소정 온도 영역에 있어 각 영역별 온도의 컨트롤이 가능하도록 하여 경량소재의 유리화 및 내부기공의 컨트롤이 가능하도록 함과 온도 영역에 있어 각 영역별로 단열막을 설치하여 열손실을 최대로 방지하도록 한 유리연마 슬러지를 사용한 경량소재 제조용 로터리형 킬른에 관한 것이다.The present invention relates to a rotary kiln for manufacturing a lightweight material using glass polishing sludge, and more specifically, to control the temperature of each region in a predetermined temperature range to enable vitrification of light materials and control of internal pores. The present invention relates to a rotary kiln for manufacturing a lightweight material using glass polishing sludge in which a thermal insulation film is installed in each temperature zone to prevent heat loss.

종래의 로터리형 킬른은 첨부도면 도 1에 도시된 바와 같이 원료를 공급하는 호퍼(100)를 통하여 공급된 원료는 진동수단(200)에 의해 정렬되어 구동모터(300)와 연결되어 작동하는 이송수단(400)을 통과시 발열체(510)가 설치된 가열수단(500)에 의해 원료(유리연마 슬러지)가 가열되며, 상기 가열수단의 가열온도는 콘트롤장치(600)에 의해 조절되는 구조로 되어 발열체와 발열체 간에 단열막이 없어서 각 구간의 독립적인 온도 구배 설정이 불가능하였다. 따라서 경량소재를 제조함에 있어 단순히 소성 온도를 조절할 뿐이어서 작업 가능한 소성 온도 범위가 좁아 지며 내부기공 컨트롤이 매우 어렵다. In the conventional rotary kiln, as shown in FIG. 1, raw materials supplied through a hopper 100 for supplying raw materials are aligned by vibrating means 200 and connected to a driving motor 300 to operate. The raw material (glass polishing sludge) is heated by the heating means 500 in which the heating element 510 is installed when passing through the 400, and the heating temperature of the heating means is controlled by the control device 600. Since there was no insulation film between the heating elements, it was impossible to set an independent temperature gradient in each section. Therefore, in the manufacture of lightweight materials, simply by controlling the firing temperature, the working temperature range becomes narrow and the internal pore control is very difficult.

또한 원료가 유리연마 슬러지이기 때문에 경량소재 제조시 로터리 킬른 내부에서 유리연마 슬러지를 연화시켜야 하지만 소성 온도 범위가 좁으므로 로터리 킬른 내부 모든 구간에서 용융점이상의 온도로 소성할 경우 내부 벽면에 유리연마슬러지가 융착 되어 경량소재 제조에 어려움이 있다. In addition, since the raw material is glass polishing sludge, it is necessary to soften the glass polishing sludge inside the rotary kiln during the manufacture of lightweight materials. There is a difficulty in manufacturing a lightweight material.

상기 종래 로터리 킬른을 사용해 경량소재를 제조시 제조조건을 RPM : 27, 1st zone : 660℃, 2st zone : 700℃, 3st zone : 630℃이며 킬른 내에서 체류시간은 약 60초로 하였을 때 미세구조는 첨부도면 도 2a 내지 도 2c에 도시된 바와 같이 전자현미경으로 촬영되었다.When manufacturing lightweight materials using the conventional rotary kiln, manufacturing conditions are RPM: 27, 1st zone: 660 ° C, 2st zone: 700 ° C, 3st zone: 630 ° C, and the microstructure has a residence time of about 60 seconds. Attached drawings were taken with an electron microscope as shown in FIGS. 2A to 2C.

상기한 종래 로터리 킬른을 사용해 경량소재를 제조할 경우 내부벽면에 원료가 융착되는 것을 방지하기 위해 소성온도를 원료의 용융점 이하로 설정하기 때문에 양질의 경량소재를 제조할 수 없다.When manufacturing a lightweight material using the conventional rotary kiln it is not possible to manufacture a good quality lightweight material because the firing temperature is set below the melting point of the raw material in order to prevent the raw material is fused to the inner wall surface.

본 발명은 상기한 종래 문제점을 감안하여 안출한 것으로서 이의 목적은 소성 온도 영역에 있어 각 영역별 온도의 컨트롤이 가능하도록 하여 경량소재의 유리화 및 내부기공의 컨트롤이 가능하도록 함과 온도 영역에 있어 각 영역별로 단열막을 설치하여 열손실을 최대로 방지하도록 한 유리연마 슬러지를 사용한 경량소재 제조용 로터리형 킬른을 제공하는데 있다.The present invention has been made in view of the above-mentioned conventional problems, and its object is to enable the control of the temperature of each region in the firing temperature range, so that the vitrification of the lightweight material and the control of the internal pores are possible, It is to provide a rotary kiln for manufacturing lightweight materials using glass polishing sludge, which is installed to prevent heat loss by installing thermal insulation film for each area.

이러한 본 발명의 목적은 원료를 공급하는 호퍼를 통하여 공급된 원료는 진 동수단에 의해 정렬되어 구동모터와 연결되어 작동하는 이송수단을 통과시 가열수단에 의해 고열의 온도로 가열하는 가열수단이 콘트롤 장치와 연결 구성되어 이루어진 유리연마 슬러지를 사용한 경량소재 제조용 로터리형 킬른에 있어서, 상기 가열수단을 4구역으로 분리하며 분리된 구역별로 소정의 온도를 갖도록 구성되며, 상기 가열수단은 내열보드로 외부가 보호되도록 되어 있고 상기 구동모터와 연결되어 작동하는 이송수단을 통과시 가열수단에 의해 고열의 온도로 가열하는 가열수단이 설치된 테이블을 소정각도로 조절하는 각도조절수단을 더 포함하여 이루어진 것을 특징으로 하는 유리연마 슬러지를 사용한 경량소재 제조용 로터리형 킬른에 의하여 달성된다.The object of the present invention is that the heating means for heating to a high temperature by the heating means when the raw material supplied through the hopper for supplying the raw material is passed by the transfer means which is aligned by the vibration means and connected to the drive motor to operate the control In a rotary kiln for manufacturing a lightweight material using glass polishing sludge composed of a device, the heating means is divided into four zones and configured to have a predetermined temperature for each divided zone. It is characterized in that it further comprises an angle adjusting means for controlling the table is provided with a heating means for heating to a high temperature by the heating means when passing through the transfer means which is connected to the drive motor to operate at a predetermined angle. A rotary kiln for the production of lightweight materials using glass polishing sludge is achieved.
