Description

Technical Field

[0001] The present invention relates to the technical field of rotary kiln systems, and particularly to a rotary kiln system with a material cleaning device. Background Art

[0002] At present, rotary kilns are widely used in many production industries such as building materials, metallurgy, chemical engineering, and solid waste treatment. Rotary kilns can be classified into cement kilns, metallurgical and chemical kilns, lime kilns, and solid waste treatment kilns according to the types of materials to be processed. Cement kilns are mainly used for calcining cement clinker. Metallurgical and chemical kilns are mainly used for magnetization roasting of lean iron ore in steel mills in the metallurgical industry, silicon thermal method for producing magnesium, oxidation roasting of chromium and nickel iron ore, roasting of high-aluminum bauxite ore in refractory material factories, and roasting of clinker and aluminum hydroxide in aluminum factories. Lime kilns (i.e., active lime kilns) are used for roasting active lime and light burned dolomite used in steel mills and ferroalloy factories. Solid waste treatment kilns are mainly used for roasting steel plant solid waste, etc.

[0003] When a rotary kiln is working, problems such as kiln skin or ring formation often occur in its kiln (the phenomenon of annular adhesion of furnace charge on the inner wall of the high-temperature zone in the rotary kiln. The slight adhesion phenomenon is called kiln skin, and the serious adhesion is called ring formation), which will cause the inner diameter of the rotary kiln to become smaller, affect the ventilation in the kiln, lead to a decrease in output and quality, and in severe cases, production has to be stopped for treatment.

[0004] Currently, the methods for treating ring formation usually include three methods: the ring burning method, the manual ring breaking method, and the rapid cooling method. Ring burning method: By adjusting the inner and outer air of the burner to change the flame shape, or changing the position of the burner, the position of the fire point is reciprocally moved. By continuously changing the thermal field, the bonded kiln ring collapses to achieve the purpose of removing the ring. This method is relatively simple and easy to operate, but has certain limitations.

[0005] (B) Manual ring breaking method: When the ring burning method is ineffective, the kiln must be stopped for treatment. The method is to wait for the kiln to cool after stopping production, and then manually enter the kiln to break the ring. This method has a long kiln stop time, high labor intensity, great damage to the kiln lining, and great danger, and is only used when necessary.

[0006] (C) Rapid cooling method: Using air or water to rapidly cool the ring. Under the condition of thermal expansion and contraction, it undergoes uneven deformation and falls off by itself. The rapid cooling method is likely to cause damage to the rotary kiln itself. Summary of the Invention
