AI Technical Summary
Existing coal mill injection oil heating devices suffer from temperature stratification caused by hot air circulating in the upper part of the oil tank, resulting in insufficient heating of the oil at the bottom and easy formation of deposits and caking, which affects heating efficiency and equipment operation stability, especially in low-temperature environments.
The forced vortex heating structure is adopted, which forms a vortex and circulation in the injection tank by obliquely injecting high-temperature gas, which enhances the stirring effect, prevents temperature stratification and dissolves deposits, improves heating uniformity and prevents caking.
It significantly improves the heating uniformity of lubricating oil, prevents temperature stratification and deposit caking, improves heating efficiency and lubricating oil fluidity, and reduces equipment maintenance costs.
