[0051] When in use, the disperser of the present invention contains carbon slurry formed by mixing carbon powder and water, which is pumped into the injection pipe by a mud pump, and then discharged from the discharge port of the injection pipe and enters between two adjacent dispersion blades through the inclined through hole of the rotating sleeve. Since the rotating sleeve rotates rapidly with the motor, the carbon slurry flowing out of the discharge pipe is driven by the dispersion blades and thrown out from the opening at the lower end of the shell by the dispersion blades and falls on the firewood in the kiln chamber. The carbon slurry contains moisture and can contact with the burning firewood to reduce the burning speed of the firewood, thereby achieving the purpose of controlling the heating rate in the kiln chamber.

[0052] When there is no need to adjust the heating speed, the piston of the cylinder extends and the control plate moves downward, so that the two protection components are separated to both sides and rotate along the rotating sleeve until the lower ends of the cover plates of the two protection components touch each other. At this time, the two protection components close the lower end opening of the shell, and the cover plate is a hollow arc-shaped plate body, and an air pipe is connected to the cover plate. When there is airflow, the temperature in the kiln chamber is difficult to be transmitted to other parts of the chamber formed by the shell and the protection components, which can extend the service life of the dispersion device.

[0053] The present invention uses carbon slurry mixed with carbon powder and water. After the temperature rise rate is controlled in the kiln chamber, water in the mixed carbon slurry of carbon powder and water evaporates, leaving only carbon powder, which can be burned without affecting the combustion process in the kiln chamber, thereby ensuring the stability of the temperature rise rate.

[0054] The dispersion device of the present invention comprises a shell, a dispersion component, a protection component and an adjustment component, wherein the shell connects the dispersion component, the protection component and the adjustment component, the dispersion component is responsible for dispersing and throwing a mixed carbon slurry of carbon powder and water pumped by a mud pump into the kiln chamber, and adjusting the temperature rise rate in the kiln chamber, the protection component is responsible for protecting the dispersion component from being affected by the high temperature in the kiln chamber when the temperature rise rate does not need to be adjusted, avoiding the reduction of the strength of the dispersion component and extending the service life, and the adjustment component is responsible for adjusting the protection component and controlling the opening and closing of the protection component.

However, the present invention is not limited to the above embodiments. Various modifications may be made to the technical solutions of the present invention without departing from the spirit of the present invention, that is, within the scope of disclosure.
