A kiln that can improve the firing quality of pigments

Abstract

The invention discloses a kiln which can enhance the sintering quality of a coloring material. The kiln comprises a kiln body and a kiln vehicle, wherein the kiln vehicle sequentially comprises a steel-plate layer, a refractory-brick layer, a perforated-brick layer, a flame-path backing-brick layer and a round sagger layer from bottom to top, wherein a plurality of flues which penetrate through the steel-plate layer are arranged in the steel-plate layer; ventilation holes which penetrate through a whole brick body are formed in a perforated brick; a plurality of round saggers are arranged in the round sagger layer, and a gap is arranged between the adjacent round saggers; a plurality of sagger flame paths are also uniformly arranged in the round sagger layer; the refractory-brick layer and the perforated-brick layer as well as the perforated-brick layer and the flame-path backing-brick layer are arranged in a staggered mode; gaps are arranged among brick bodies in the same brick-body layer. The coloring material is heated and sintered by utilizing the kiln, so that the temperature difference of all parts of the whole kiln is decreased to 5 DEG C from original 50 DEG C, the production quality is guaranteed, and the temperature increase is uniformly quickened; compared with the original sintering time, the whole sintering time of the coloring material is shortened by 10 to 20 percent; the energy-source consumption of the coloring material in the whole sintering process is reduced by 20 to 35 percent.

Description

technical field [0001] The invention relates to the field of pigment firing equipment, in particular to a kiln capable of improving the quality of pigment firing. Background technique [0002] The shuttle kiln for pigments is mainly used for the firing of pigments. In the traditional production method of pigments, the unreasonable setting of the kiln structure affects the quality of firing: 1. The use of square saggers leads to slow temperature rise 2. The unreasonable setting of the hot air channel leads to a large temperature difference between the sagger piles on the trolley; 3. The temperature control of the traditional burner is too extensive, which is not conducive to stabilizing the production quality. The unreasonable setting of the above structures will lead to fluctuations in production quality and increased energy consumption of equipment, which cannot guarantee the firing quality and does not conform to the environmental protection concept of energy saving and em...
