Efficient, energy-saving and environment-friendly high-temperature calcination device for electrode paste raw materials

Abstract

The invention provides an efficient, energy-saving and environment-friendly high-temperature calcination device for electrode paste raw materials. The efficient, energy-saving and environment-friendlyhigh-temperature calcination device for the electrode paste raw materials comprises a hearth, a chimney, a feeding mechanism, a discharging mechanism and a controller. According to the technical scheme, every two unit furnace walls in each furnace unit communicate with each other; when flowing in each furnace unit, high-temperature smoke can randomly enter one unit furnace wall to make sure thatthe temperature of the center of the hearth and the temperature of the edges of the hearth are uniform and consistent, and thus, the calcination quality of the calcined materials is made uniform; combustible volatile matter generated after calcination of the raw materials enters unit flues via micropores in the unit furnace walls, so that heat is provided for the hearth, and the situation that thevolatile matter enters the atmosphere and pollutes the environment is prevented; opening and closing of electric brake valves are synchronously controlled through a timer, so that it is ensured thatthe feeding quantities of material channels are consistent; a conveying part in a discharging mechanism is formed by a plurality of conveying units which are of the same structure and are arrayed linearly, and the conveying units which operate stably can ensure that materials in the material channels have the same conveying opportunity, so that uniform discharging is ensured, and the process stability of the calcined materials is ensured.

Description

technical field [0001] The invention relates to the technical field of carbon brick and electrode paste production equipment, in particular to high-temperature calcining equipment for high-efficiency, energy-saving and environment-friendly electrode paste raw materials. Background technique [0002] Ordinary calciner is a high-temperature heat treatment equipment for the production of cathode carbon blocks for aluminum, electrode paste raw materials for super-large submerged arc furnaces, and electric calcined coal. By heating the coal blocks, the volatile components in the coal blocks are dry-distilled. It is carried out in an environment where dry distillation of coal is used to make carbon materials, and a part of the gas containing combustibles is discharged from the chimney of the general forge. After being ignited, the smoke is emitted into the atmosphere. This emptying method not only wastes energy but also pollutes the air. There is a temperature gradient in the hea...

AI Technical Summary

Problems solved by technology

This emptying method not only wastes energy but also pollutes the air.

There is a temperature gradient in the hearth of the existing common calciner, and the temperature in the center of the furnace is about 100-200°C higher than the temperature at the edge of the furnace, so that the calcined quality of the calcined material is uneven. During the feeding process, the material in the center of the furnace is discharged quickly, while the material is discharged slowly at the edge of the furnace, which causes a bias flow and affects the process stability of the calcined material
