Treatment method and tool for rotary kiln flame high-temperature belt formed ring

Abstract

The invention discloses a treatment method and tool for a rotary kiln flame high-temperature belt formed ring. The treatment method includes the steps that (1) a plurality of through holes in multiple rows and multiple lines are formed in a rotary kiln barrel of a flame high-temperature belt zone; (2) a castable precast block is constructed, and a horn-shaped center hole is formed in the center of the castable precast block; (3) the castable precast block is constructed in heat insulation cotton of the flame high-temperature belt zone, and the through holes and the center hole form intercommunicating holes; (4) production is stopped after the ring is formed, and an air pick extends into the intercommunicating holes to knock the formed ring out; (5) after the formed ring is knocked out, the tool is used, quick-drying refactory castables are filled inside and outside pipe holes of the tool, the intercommunicating holes are plugged, and then reproduction can be carried out. The treatment method is quick and convenient to realize, the tool is simple in structure, convenient to use and practical, the formed ring in a rotary kiln can be knocked out under the condition that a furnace body is not cooled, production can be carried out instantly, long-time kiln halt is not needed, maintenance cost is reduced, and continuity of production can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of a rotary kiln, in particular to a method for treating ring formation in a flame high temperature zone of a rotary kiln and a special tool thereof. Background technique [0002] At present, after the rotary kiln for clinker production has been used for a period of time, due to the complex composition of the kiln wall masonry materials, the mixing of materials is not uniform or sufficient, resulting in the relative concentration of some low-melting materials, which are liquid and viscous at high temperatures. The refractory castables on the wall are bonded, and the unmelted materials with higher refractoriness that enter are also gradually bonded, forming high-temperature zone rings. In the actual production process, the ring formation has a great relationship with the length of the burner flame, the concentration or divergence of the flame. According to the usual roasting in the current production, the fla...

Problems solved by technology

Once the rotary kiln forms a ring, it is difficult to restore the normal use state. Over time, the entire kiln will be blocked and production cannot continue

Now the industry generally needs to clean once every three months. The cleaning method is to stop the kiln and let the rotary kiln cool down. The operator enters the kiln to clean it with a pick, and then heats up the rotary kiln to continue production. Cooling, processing, and heating up The time is long, continuous production cannot be formed, and more fuel is used for heating, which causes huge waste to the enterprise. The labor intensity of the workers is high during processing, and the working environment is harsh.
