Description

Technical Field

[0001] The utility model relates to a kiln spray gun and belongs to the technical field of kiln spray guns. Background Art

[0002] A kiln is a furnace used to fire ceramics and sculptures or to fuse enamel to the surface of metal objects. It is usually made of bricks and stones. It can be made into various sizes according to needs and can be operated by combustible gas, oil or electricity.

[0003] During the glass melting process, a large amount of foam will be generated in the glass liquid because of the introduction of air and moisture into the gaps between the raw materials and the generation of gas by chemical reactions between the raw materials. The existence of this foam layer is very unfavorable to the production of the kiln. The general practice is to spray a defoaming agent into the kiln to eliminate the foam layer. At present, the full oxygen combustion kiln generally uses a hole in the breast wall on one side of the furnace body and adds a spray gun to continuously spray the defoaming agent; the air combustion spray gun will add a spray gun to the heat storage chamber or small furnace on both sides of the furnace body to spray the defoaming agent. Because the air combustion kiln needs to regularly change the direction of air and fuel addition during the production process, this change The operation of changing direction is called "reversing" on the kiln, so the defoaming agent spray gun also needs to follow the reversing operation and spray the defoaming agent intermittently. During the reversing period, because the spray gun is still inside the kiln at 1600℃, although there is a protective device outside the spray gun, because there is no material cooling, the spray gun is in a "dry burning" state for a long time. The existence of this state will cause a small amount of residual material at the spray gun mouth to carbonize at high temperature, which will clog the spray gun after a long time, causing the spray effect to deteriorate and thus affecting the use of the defoaming agent; on the other hand, it will greatly reduce the service life of the spray gun, and will also cause poor atomization of the spray gun and affect the use of the defoaming agent.
