AI Technical Summary

Technical Problem

Existing laboratory coal tar pitch melting devices suffer from uneven heating, low melting efficiency, and an inability to raise or lower the stirring mechanism, leading to inconvenience and environmental pollution.

Method used

A coal tar pitch melting device was designed, comprising a cover plate driven by a hydraulic cylinder, annularly distributed heating tubes, and a stirring mechanism. The cover plate is raised and lowered by the hydraulic cylinder, enabling convenient maintenance of the stirring mechanism. The annular heating tubes ensure uniform heating, and an air purification device is connected to the exhaust pipe to treat harmful gases.

Benefits of technology

This technology enables uniform heating and rapid melting of coal tar pitch, reduces environmental pollution, improves operational convenience and melting efficiency, and ensures the quality of coal tar pitch and precise control of experiments.
