Description

Technical Field

[0001] The utility model relates to the technical field of utilization of waste heat from smelting ladle connection, in particular to a smelting ladle heat dissipation and waste heat recovery device. Background Art

[0002] The smelting process of fused white corundum and fused spinel is basically the process of melting and recrystallizing industrial alumina powder and light-burned magnesium powder, which has the advantages of simple process, short flow and low product cost. The industrial alumina and light-burned magnesium powder treated by electric melting with arc discharge in an electric furnace are in a molten liquid state, and the solution temperature can reach 2000℃. The high-temperature solution can be solidified into white corundum and spinel ingots after cooling for about 4 hours. After smelting, the melt in the smelting furnace needs to be poured into a special container for cooling and crystallization. The cooling and crystallization of the ingot in production is generally carried out in a connection package, the shape of which is an inverted trapezoid, and corundum sand is laid inside the steel plate to protect the external steel shell and provide heat insulation.

[0003] In actual production, the traditional package has the following shortcomings; first, the shape of the molten block in the traditional package is flat and disc-shaped, the molten block is high, the upper section is large and the heat dissipation is fast, and the lower section is close to the sand pad and the heat dissipation is slow. This causes the upper and lower heat dissipation rates of the melt to be uneven during the cooling process, resulting in a small amount of melt in the lower part that has not completely solidified and crystallized when the upper part of the molten block has been cooled and solidified; at this time, the strength of the molten block is low. When workers use special clamps to lift the molten block out of the package, collapse or leakage may occur during the lifting process, causing great safety hazards; secondly, the package emits a lot of heat during the cooling process in the workshop. Even after 4 hours, the surface temperature of the molten block is still 500~600℃. In summer, the ventilation and heat exchange effect inside the workshop is poor. The high temperature environment can easily cause adverse reactions such as heatstroke among workers, greatly affecting work efficiency. Summary of the invention

The air inlet of the fan is connected to the end of the hot air duct, the front end of the heat storage duct is connected to the air outlet of the fan, and the rear end of the heat storage duct leads to the hot water storage tank.
