AI Technical Summary

Technical Problem

Traditional water-cooled furnace covers suffer from insufficient sealing reliability, poor cooling efficiency and uniformity, and inconvenience of operation. In particular, when used under high temperature and mechanical load, the seal is prone to failure, the cooling is uneven, and the hoisting is inconvenient.

Method used

It adopts a spiral water channel design, a double sealing structure and a distance adjustment component. The spiral water channel extends the water flow path to enhance heat exchange efficiency, the double sealing structure improves sealing reliability, and the distance adjustment component is compatible with different hoisting tools to enhance operation convenience.

Benefits of technology

It improves the sealing reliability and cooling efficiency of the water-cooled furnace cover, reduces equipment maintenance frequency and energy consumption, and enhances the stability and safety of hoisting.

Abstract

The utility model discloses a novel water -cooled furnace cover belongs to water -cooled furnace cover technical field, including the furnace cover, the inside fixed spiral water channel of furnace cover, and the water inlet and water outlet of spiral water channel all extend to the outside of furnace cover, and the inner surface of furnace cover is provided with sealing assembly, and sealing assembly effectively solved the problem that traditional single -way seal is easily invalid, even if the first sealing ring appears the leakage because of high temperature ageing or wear and tear, and the second sealing ring still can form effective barrier, and spiral water channel design is through the extension water flow path, and enhances the water flow disturbance, makes the heat exchange area of cooling water and furnace cover to obtain the increase, avoided the thermal stress crack of partial overheating, improved the heat exchange efficiency, and the equipment replacement frequency and maintenance cost were reduced greatly.
