In order to achieve the above purpose, the utility model adopts the following technical scheme:
a waste heat preheating device of a wide roller kiln comprises a roller kiln body, wherein a combustion bin is arranged at the bottom of the roller kiln body, and the roller kiln body is communicated with the combustion bin through a sintering port; a hot gas outlet is arranged above the roller kiln body; a preheating bin is arranged on one side edge of the roller kiln body, and the preheating bin is communicated with the roller kiln body above the side wall of the roller kiln body; the preheating bin is provided with an inclined side wall, a nozzle with an inclined downward opening is arranged on the inclined side wall, and the nozzle is communicated with a hot gas outlet of the roller kiln bin body through a pipeline.
And a combustion spray gun is arranged in the combustion bin.
A roller way transmission belt is arranged in the roller way kiln body, and a ceramic tile green body to be sintered is placed on the roller way transmission belt.
The side wall of the roller kiln body is provided with a discharge hole which can be opened and closed.
The bottom of the preheating bin is provided with a transmission belt, and the ceramic tile green bodies are conveyed to the interior of the roller kiln bin body through the transmission belt.
And a carrying device is also arranged in the roller way bin body.
The utility model has the advantages that: the waste heat preheating device for the wide roller kiln realizes one-time heating to complete the sintering process of the ceramic tile, and improves the production efficiency and saves energy compared with twice sintering in the traditional firing process.
