Preheating decomposition device for cement production

The utility model discloses a cement production preheating decomposition device, which comprises a processing box, the inner wall of the processing box is fixedly connected with a fixed plate, the inner bottom wall of the processing box is provided with a heating mechanism, the left side surface of the processing box is fixedly connected with a motor, the left side surface of the processing box is fixedly embedded with a first bearing, and the first bearing is fixedly embedded with a second bearing. And a second bearing is fixedly embedded in the inner wall of the processing box. According to the device, through cooperation of sealing plates, a heating mechanism, an air draft pump and a decomposition box, when processing raw materials generate toxic gas, the two sealing plates are placed in a horizontal state to prevent the toxic gas from being discharged, then the air draft pump is used for extracting the toxic gas in the processing box, the extracted toxic gas can be conveyed into the decomposition box, and
