Abstract

The invention discloses a method and a device for feeding rice husks into a rice husk combustion furnace for light calcium carbonate. The method is characterized in that a conveying pipeline is arranged below a rice husk stacking site, an air blower is arranged at an end of the conveying pipeline, an air outlet of the air blower is butted to an inlet of the conveying pipeline, air can be deliveredto the conveying pipeline, an outlet of the conveying pipeline extends into a hearth of the rice husk combustion furnace, a rice husk inlet is formed in the middle of the conveying pipeline and is particularly formed in a position below the rice husk stacking site, and the rice husks can be fed into the conveying pipeline from the rice husk inlet and can be blown into the hearth of the rice huskcombustion furnace; a control valve for controlling the conveying quantities of the rice husks is arranged between the rice husk inlet of the conveying pipeline and an outlet in the hearth of the ricehusk combustion furnace, and the quantities of the rice husks which are fed into the rice husk combustion furnace can be controlled by the control valve, so that the combustion temperatures of the rice husk combustion furnace and generated heat can be controlled.

Description

technical field [0001] The invention relates to a method and device for producing light calcium carbonate, in particular to a method and device for adding dye to a light calcium carbonate chaff burning furnace, and to a method for adding dye to a light calcium carbonate chaff burning furnace The device is more energy-saving, environmentally friendly, resource-saving, and realizes intelligent control, and belongs to the technical field of light calcium carbonate production. Background technique [0002] Light Calcium Carbonate (Light Calcium Carbonate) is also called Precipitated Calcium Carbonate (PCC for short).
