Embodiment
For the present invention is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Fig. 1 is sulphur provided by the invention molding device schematic diagram under water, described sulphur under water molding device comprises the molten sulfur distributing disc 1 of carrying vapour chuck, moulding tank 2 is positioned at molten sulfur distributing disc 1 below, moulding tank 2 bottoms connect draining screen 3 and cooling trough 4 by stopcock, draining screen 3 bottoms are also connected with cooling trough 4, cooling trough 4 connects water cooler 5 by cooling-water pump 6, and water cooler 5 connects moulding tank 2; Draining screen 3 connects feed bin 8 by closed belt conveyer 7.
Steam jacket is located on molten sulfur distributing disc 1, the steam jacket on low-pressure steam pipe network connecting fluid sulfur distribution dish 1, and with the temperature of the molten sulfur in maintenance medium sulfur distribution dish 1, sulfur vapor is emptying by the high point of ventilator 9.Some distribution holes are arranged at molten sulfur distributing disc 1 bottom.
Moulding tank 2 bottoms are provided with radar level gauge.Moulding tank 2 tops are provided with overflow groove, and overflow groove connects cooling trough 4.
Water cooler 5 is plate-type heat exchangers, and circulating water cooling system connects water cooler 5, and circulating water enters water cooler 5, and the circulating hot water after heat exchange is discharged.
Sulphur is moulding process under water, adopts above-mentioned sulphur molding device under water, comprises the following steps:
