Detailed Description

The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way. The unit module components, structures, mechanisms, sensors and other devices referred to in the following examples are all conventional and commercially available products unless otherwise specified.

Example (b): as shown in fig. 1-3, a cooling device for white corundum smelting comprises a furnace body 1 and a furnace cover arranged at the top of the furnace body 1, wherein in order to reduce heat loss and damage of temperature in the furnace to the furnace body 1, a heat insulation layer 3 is arranged on the inner side of the furnace body 1 and the bottom side of the furnace cover 2, and a lifting ring 20 is arranged at the top of the furnace cover 2; the furnace cover 2 comprises a disc-shaped upper supporting plate 4 and a lower sealing plate, the lower sealing plate comprises an annular outer fixing plate 5, a lower movable plate 6 and an inner fixing plate 7, the outer fixing plate 5 is used for covering the furnace mouth, the outer fixing plate 5 is fixedly connected with the upper supporting plate 4 through 3-5 first supporting rods 8, the inner fixing plate 7 is fixedly connected with the upper supporting plate 4 through 3-5 third supporting rods 9, the lower movable plate 6 is fixedly connected with an upper movable plate 11 through 3-5 second supporting rods 10, the upper movable plate 11 is fixedly connected with a piston end of a lifting hydraulic cylinder 12, a cylinder body part of the lifting hydraulic cylinder 12 is fixedly arranged on the upper supporting plate 4, a cooling water pipe 13 is arranged between the upper movable plate 11 and the lower movable plate 6, the cooling water pipe 13 spirally surrounds the second supporting rods 10, and two ends of the cooling water pipe 13 respectively penetrate through the upper movable plate 11 and then are respectively connected with a water inlet pipe 14, The water outlet pipe 15 is connected.
