Pre-incineration device for cement production

The invention relates to the technical field of cement production, in particular to a pre-incineration device for cement production, which is used for solving the problem of poor material combustion effect of an existing device, and comprises a combustion platform, the combustion platform comprises a bottom plate, the bottom plate is obliquely arranged, and a plurality of combustion modules are arranged on the bottom plate along the inclination direction of the bottom plate; an air injection gap is formed between every two vertically adjacent combustion modules and provided with an air injection opening, and the air injection openings face the material moving direction. The combustion module is provided with a guide plate which obliquely extends upwards from the upper edge of the air nozzle; the wall attachment effect is generated when the air injection source rushes into the air injection gap, the original flow direction of air flow is changed, and the air flow directionally moves along the wall face of the
