One-time stacking burning tunnel kiln

Abstract

The invention discloses a one-time stacking burning tunnel kiln. The one-time stacking burning tunnel kiln comprises a tunnel kiln main body structure and a flow guide device; the tunnel kiln main body structure is divided into a plurality of working zones from the kiln head to the kiln tail of the tunnel kiln main body structure, each working zone is provided with a kiln chamber and an interlayer, and the kiln chambers communicate with the interlayers through smoke holes; the plurality of working zones comprise the first working zone and the second working zone, and the flue gas temperature in the first working zone is higher than that in the second working zone; and the flow guide device is used for guiding flue gas in the interlayer corresponding to the first working zone into the kiln chamber corresponding to the second working zone. According to the one-time stacking burning tunnel kiln, the operation parameters (including temperature, air volume, air speed and the like) of the working zones are adjusted, so that different varieties of sintered brick wet blanks are correspondingly treated, and the quality of sintered bricks is ensured.

Description

technical field [0001] The invention relates to the technical field of incineration equipment, in particular to a tunnel kiln for primary code-firing. Background technique [0002] One-time code firing refers to the fact that the wet billet is directly put into the kiln for one-time firing without drying or biscuit firing. One-time code-fired tunnel kiln has simple production process, low investment, less land occupation, less labor, energy saving, high output, high labor efficiency of workers, low production cost, complete product appearance and uniform color, and is easy to realize mechanized code blank and Advantages such as depalletizing. [0003] However, due to the different components of different types of fired bricks, there are differences in the drying cycle of the green body and the firing cycle of the roasting kiln in one-time code firing, and the time intervals between the drying zone and the firing zone are different. The difference from the throughput rate o...

[0003] However, due to the different components of different types of fired bricks, there are differences in the drying cycle of the green body and the firing cycle of the roasting kiln in one-time code firing, and the time intervals between the drying zone and the firing zone are different. The throughput rate is different from that of the roasting process, which leads to the imbalance of each process and the disorder of production order, which affects the quality of sintered bricks
