Horizontal double-spiral band drum-type resistance furnace system and technological process thereof

Abstract

The invention relates to the technical field of resistance furnaces, in particular to a horizontal double-spiral band drum-type resistance furnace system and a technological process thereof. The system comprises a mobile loading machine, a double-spiral band resistance furnace, a condenser and a cooling furnace. The double-spiral band resistance furnace has a unique double-spiral band design, anda resistance furnace inner spiral band and a resistance furnace outer spiral band are used in cooperation, wherein the resistance furnace inner spiral band pushes material from the middle to the two ends, and the resistance furnace outer spiral band with a coiled form matched with the rotation direction pushes the material from the two ends to the middle, so that convective mixing is formed, the material is evenly mixed in relatively short time, and thus the heating efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of resistance furnaces, in particular to a horizontal double-screw belt drum-type resistance furnace system and its process flow. Background technique [0002] Existing resistance furnaces are mainly used for drying, roasting and cooling negative electrode materials, metallurgy and powder materials. However, the existing electric resistance furnace does not achieve good results for powdery and granular objects that are viscous or cohesive and easy to stick to the wall, and are easy to stick. [0003] Traditional resistance furnaces generally use conveyor belts for feeding, which has a great impact on the environment and has a great impact on the health of workers. [0004] The traditional electric resistance furnace is generally straight plate stirring, the stirring direction is single, and the material is stirred unevenly, which leads to uneven heating, low thermal efficiency, and reduced output.

AI Technical Summary

Problems solved by technology

However, for viscous or cohesive powdery and granular objects with poor fluidity, the existing resistance furnaces cannot achieve good results and are easy to stick

[0003] Traditional resistance furnaces generally use conveyor belts for feeding, which has a great impact on the environment and has a great impact on the health of workers.

[0004] The traditional electric resistance furnace is generally straight-sheet stirring, the stirring direction is single, and the material is unevenly stirred, which leads to uneven heating, low thermal efficiency, and reduced output.

[0005] In addition, the traditional resistance furnace is limited by the fact that it cannot cool down quickly. After the material is discharged, the temperature inside the furnace is too high to load the material in time, which affects the production of the next furnace. It can only be produced in an intermittent production mode, that is, once the heating is completed. After that, after the heat dissipation is completed, proceed to the next production

[0006] Restricted by factors such as material stickiness, traditional resistance furnaces generally use inclined unloading for unloading, which has a long unloading cycle, is not clean, and consumes a lot of energy.

[0007] In addition, the waste gas generated during the production of traditional electric resistance furnaces cannot be effectively treated, which seriously pollutes the environment
