The invention discloses a magnetic ferrite production device, which comprises a machine body, a feeding valve pipe, a material discharging valve pipe, a heating external coil, a circulation heater, an electric stirring machine, a gradient magnetic guide assembly, an air heat exchanger and an air compressor, wherein a material feeding opening is formed in an upper end sealing cover of the machine body; a material discharging opening is formed in a lower end sealing bottom of the machine body; the material discharging end of the material feeding valve pipe passes through the material feeding opening formed in the machine body and then extends into the machine body; the material feeding end of the material discharging valve pipe is connected with the material discharging opening of the machine body; the heating external coil is arranged on the outer periphery surface of the machine body in a surrounding way; the circulation heater is used for heating a heating medium; a heating air outlet is connected in parallel into the material discharging opening of the machine body through a connecting pipe; a compressed air outlet of the air compressor is connected with an air inlet of the air heat exchanger. When the magnetic ferrite production device provided by the invention is used for treating electric plating sludge, the goal of changing all the electric plating sludge into resources can be achieved; the problems of large occupied area, resource waste and easiness of secondary mineralization dissolution ecological risk due to a filling method can be solved.
Description
technical field [0001] The invention relates to the technical field of environmental protection equipment for recycling hazardous waste containing heavy metals, in particular to the technical field of electronic equipment for the production of electronic material magnetic ferrite, and in particular to a magnetic ferrite production device. Background technique [0002] The traditional treatment method for electroplating sludge and heavy metal-containing sludge in other industries is harmless treatment. At present, most of them use cement embedding to stabilize and no longer dissolve, and finally use landfill for disposal. Another treatment method is to add silicate to melt at a high temperature above 1400°C to achieve vitrification, so that after the heavy metals are stabilized, landfill is finally used for disposal. The disadvantages of these two treatment methods are that they occupy a large area, waste a lot of land resources, and waste hazardous waste resources. After lon...
