Dry graphite powder dipping istructure and method

Abstract

The invention relates to the field of mechanics, in particular to a dry graphite powder dipping structure and method. The structure comprises a kerosene spraying structure. The kerosene spraying structure comprises a rack. A platform is arranged on the rack. A kerosene tank is arranged on the platform. More than one sprayer stretches out of the kerosene tank through pipelines. An atomizing chamberhood above the platform is further arranged. A holding platform is arranged in the middle. Objects can be placed on the holding platform. The sprayers can spray kerosene towards the holding platform.The dry graphite powder dipping structure and the method have the beneficial effects that when the structure is used, a steel claw is arranged above the holding platform, the sprayers spray out the kerosene, and the kerosene can be sprayed to the steel claw; it should be noted that the sprayers can be fixed or rotational, and of course, the sprayers are high-pressure sprayers preferentially; andit is should be noted that high pressure of the high-pressure sprayers can be provided directly by a pump or high-pressure airflow.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a structure and method of dry powder dipped in graphite. Background technique [0002] In the anode assembly process of the electrolytic aluminum industry, before the prebaked anode and steel claws are cast and assembled, a layer of graphite must be coated on the surface of the steel claws to avoid melting cast iron and steel claws from sticking to death during casting and assembly. At present, the wet dipping method is widely used in graphite coating in the industry: the specific working process is to first mix graphite powder and kerosene into a mixed solution in an appropriate proportion, then the steel claws invade into the mixed solution, and a layer of kerosene-graphite mixed liquid film is attached to the surface of the steel claws . Then use the heating device to dry the kerosene in the kerosene-graphite mixed liquid film, leaving the attached graphite layer on the surface of the ...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned graphite dipping process has the following defects and problems in practical application: because graphite and kerosene are in the state of a mixed liquid, they are easy to precipitate, resulting in poor uniformity and stability of the mixed liquid, making the mixed liquid film dipped on the steel claws uneven and stable, and it is difficult to achieve the process. Quality requirements; kerosene volatilization or combustion during drying has a great impact on ambient air quality, and secondary damage to the uneven and stable mixed liquid film; there is a fire or explosion hazard when drying with gas; kerosene volatilization or combustion forms waste of energy, environmental pollution

However, in actual work, the gas needs to be burned with a large flame, and the hot air flow of the combustion will cause damage to the uniformity of the graphite layer when the steel claw is dried.

Burning gas and kerosene pollute the environment. To use this kind of equipment, you need to connect gas pipelines or gas storage equipment, which increases the fire hazard. Therefore, this process is not as widely used as intermediate frequency drying.

[0007] The graphite dipping process in the wet dipping process is to immerse the steel claws directly into the graphite kerosene mixed liquid tank. Generally, the mixed liquid will be stirred by the compressed air method. The principle of this stirring structure is simple but the practical effect is poor, and it is often supplemented by manual stirring.
