Description
본 발명은 글라스비드(glass beads)제조용 가스로의 가열부 내벽에 유리 슬러지가 형성되지 않도록 가열부의 외벽을 적절히 냉각시켜주는 냉각장치에 관한 것이다.The present invention relates to a cooling apparatus for appropriately cooling the outer wall of the heating unit so that glass sludge is not formed on the inner wall of the heating unit to produce glass beads.
일반적으로 글라스비드 제조용 가스로는 상부 본체와 하부 가열부로 구성되고 하부 가열부에는 수개의 가스버너와 재료(유리분말) 투입구가 설치되어 있으며, 재료 투입구로 투입된 유리분말은 가스버너의 강력한 화염에 의하여 본체쪽으로 상승하면서 약 1,000℃~1,100℃의 고온으로 용융되어 비드화하고 본체에서 비드화가 완성된 다음 본체의 외곽쪽 하부에 형성된 배출부로 낙하하여 수집통으로 수집되는 방법으로 제조되며, 이때 가열부의 내부는 약 1,000℃ 정도가 되나 외벽이 외기와 접하고 있는 가열부의 내벽온도는 약 950℃ 정도밖에 되지 않으므로 가열부에서 화염과 함께 상승중이던 유리분말의 일부가 외측으로 밀려 내벽에 닿아 녹아 붙고, 또한 본체까지 상승하여 비드화가 완성된 후 낙하하는 비드중의 일부도 외곽의 배출부로 낙하하지 못하고 가열부쪽으로 다시 떨어지면서 가열부의 내벽에 닿아 녹아 붙으므로 가열부의 내벽에는 항상 두껍게 유리 슬러지가 형성되는 것이다.Generally, the glass bead gas is composed of an upper body and a lower heating part, and several gas burners and a material (glass powder) inlet are installed in the lower heating part, and the glass powder injected into the material inlet is formed by a strong flame of the gas burner. It is manufactured by melting and beading at a high temperature of about 1,000 ° C. to 1,100 ° C. as it rises toward the side, and after the beading is completed in the main body, falls to the discharge part formed at the lower portion of the outer part of the main body and is collected by a collecting container. The inner wall temperature of the heating part which is about 1,000 ° C but the outer wall is in contact with the outside air is only about 950 ° C. Therefore, a part of the glass powder which is rising together with the flame in the heating part is pushed outward and touches the inner wall to melt and rises to the main body. Some of the beads falling after the beading is completed cannot fall to the outer discharge part Then, it falls back toward the heating part and touches and melts on the inner wall of the heating part, so that thick sludge is always formed on the inner wall of the heating part.
가열부내에 유리 슬러지가 형성되면 가열부 내부가 그만큼 협소하게 되고 따라서 그만큼 생산량이 감소하게 될 뿐 아니라 유리 슬러지는 대체로 평활하게 형성되는 것이 아니고 수없이 굴곡된 형상으로 형성되기 때문에 상승하는 화염의 흐름에 저항을 주어 흐름을 왜곡시키며 이와 같이 화염의 흐름이 원활하지 못하고 왜곡되면 생산성 저하와 함께 제품의 품질에도 문제를 초래하게 되는 것이다.When the glass sludge is formed in the heating part, the inside of the heating part is narrowed accordingly, and thus the yield is reduced. Also, the glass sludge is not formed generally smoothly but is formed in a number of curved shapes. It gives resistance to distortion of the flow, and if the flow of flame is not smooth and distorted like this, it will cause a problem in the quality of the product along with the decrease in productivity.
따라서 종래에는 이와 같이 가열부에 형성되는 유리 슬러지를 제거하기 위하여 가열부 외벽에 컴퓨터에 의하여 제어되는 여러개의 전자식 자동햄머를 설치하고 이들 햄머들이 수시로 가열부의 외벽을 타격하여 충격을 주도록 하므로서 내벽의 슬러지가 떨어져 제거되도록 하였다.Therefore, in the related art, in order to remove the glass sludge formed in the heating part, a plurality of electronic automatic hammers controlled by a computer are installed on the outer wall of the heating part, and these hammers frequently strike the outer wall of the heating part, thereby impacting the sludge of the inner wall. Was removed to remove.
그러나 이러한 외벽 충격방법은 전자햄머, 컴퓨터등의 설치운영비가 비쌀 뿐아니라 내벽의 슬러지 제거가 충분하게 되지 않으므로 때때로 로의 불을 끄고 로를 냉각시켜 슬러지를 모두 제거한 다음 다시 가동하여야 하는 등의 문제가 있는 것이었다.However, this external wall impact method is not only expensive to install and operate electronic hammers and computers, but also it is not enough to remove sludge from the inner wall, so it is sometimes necessary to turn off the furnace's fire, cool the furnace, remove all the sludge, and then start the operation again. Was.
본 발명에서는 이러한 문제점을 해결하여 가열부 외벽에 냉각조를 설치하고 일정온도의 냉각수를 회전시켜 가열부 내벽의 온도를 적절히 냉각시켜 주므로서 슬러지가 내벽에 붙지 않고 저절로 낙하도록 한 것이다.In the present invention to solve this problem, the cooling tank is installed on the outer wall of the heating unit and the cooling water at a predetermined temperature is cooled to properly cool the temperature of the inner wall of the heating unit so that the sludge does not adhere to the inner wall.
다시 말하면 약 1,000℃ 온도로 가열 용융된 유리분말이나 비드가 950℃ 정도의 가열부 내벽에는 엿처럼 녹아 달라붙지만 내벽의 온도가 750℃ 정도가 되면 유리분말이나 비드가 내벽에 닿는 순간 온도 차이에 의한 냉각 수축 작용 때문에 내벽에 달라붙지 못하고 떨어져 내리므로 슬러지가 형성되지 않는 것이다.In other words, the glass powder or beads melted at a temperature of about 1,000 ° C melt and adhere to the inner wall of the heating part at about 950 ° C. However, when the temperature of the inner wall reaches about 750 ° C, the glass powder or bead touches the inner wall. Due to the cooling shrinkage action, the sludge is not formed because it does not stick to the inner wall and falls down.
가열중인 가열부의 내벽온도를 적절히 냉각시키는 것은 매우 중요한 것이다.It is very important to properly cool the inner wall temperature of the heating portion being heated.
왜냐하면 내벽 온도를 지나치게 냉각시키면 냉각 에너지가 많이 소요될 뿐아니라 1,000℃ 정도로 유지되어야 하는 가열부 내부온도에 지장을 초래하게 되며 반대로 내벽 온도가 적정온도 이상으로 높아지면 슬러지 제거효과가 감소되기 때문이다.Because excessive cooling of the inner wall temperature not only consumes a lot of cooling energy, but also causes a problem in the internal temperature of the heating part which should be maintained at about 1,000 ° C. On the contrary, when the inner wall temperature rises above an appropriate temperature, the sludge removal effect is reduced.
시험한바 내벽의 온도를 약 750℃ 정도로 유지하면 가열부내의 온도를 비드화에 적절한 1,000℃~1,100℃로 유지하는데 지장이 없으면서 슬러지가 형성되지 않았으며, 내벽의 온도를 약 750℃ 정도로 유지하기 위하여는 외벽의 온도가 75℃~80℃가 되도록 냉각수에 의한 냉각을 해주어야 하는 것이다.When the temperature of the inner wall was maintained at about 750 ℃, the sludge was not formed without any problem in maintaining the temperature in the heating part at 1,000 ~ 1,100 ℃ suitable for beading, and to maintain the temperature of the inner wall at about 750 ℃. Is to be cooled by the cooling water so that the temperature of the outer wall is 75 ℃ ~ 80 ℃.

이와 같이 구성된 본 발명은 약 30℃~35℃ 정도의 냉각수를 유입구(5)를 통하여 냉각조(3)에 공급하므로서 가열부(2)의 외벽온도가 약 75℃~80℃ 정도로 냉각되게 하면 가열부(2)의 내벽온도가 약 750℃ 정도가 되고, 따라서 약 1,000℃로 가열 용융되었던 유리분말이나 비드가 내벽에 닿아도 달라붙지 않고 급작히 냉각 수축되면서 아래로 떨어져 내리게 되므로 슬러지가 형성되지 않는 것이다.The present invention configured as described above is heated when the outer wall temperature of the heating unit 2 is cooled to about 75 ° C to 80 ° C by supplying cooling water of about 30 ° C to 35 ° C to the cooling tank 3 through the inlet 5. The inner wall temperature of the part 2 is about 750 ° C., so that the glass powder or beads that have been heated and melted at about 1,000 ° C. do not adhere to the inner wall but are suddenly cooled and contracted and fall down. will be.
본 발명의 냉각장치에 의하여 가열부(2) 내벽에 유리 슬러지가 형성되지 않으므로 값비싼 전자제어식 햄머를 설치 운용하여가 수시로 로의 불을 끄고 냉각시킬 필요가 없고, 가열부(2) 내부공간의 협소화와 화염의 흐름에 대한 왜곡으로 생산성과 품질이 저하되는 것을 방지할 수 있는 효과가 있는 것이다.Glass sludge is not formed on the inner wall of the heating part 2 by the cooling device of the present invention, so that expensive electronically controlled hammers are installed and operated, and the furnace does not need to be turned off and cooled at any time, and the space inside the heating part 2 is narrowed. Distortion of the flow of the flames and the effect is to prevent the degradation of productivity and quality.
