Equipment for automatically preparing sulfur solid

The invention discloses equipment for automatically preparing sulfur solids. The equipment comprises a pyrite crushing mechanism, a sealing mechanism, a stirring mechanism and an iron trioxide discharging mechanism, when the equipment is in use, the pyrite is firstly put into the pyrite crushing mechanism to be crushed into powder, then the pyrite powder is put into the fluidized bed furnace, the sealing mechanism is started, the fluidized bed furnace is sealed, gas is prevented from being exposed, and the equipment is used for discharging the pyrite. Then, the heating ring heats the fluidized bed furnace, a stirring part is started, the pyrite and air are fully contacted and reacted, sulfur dioxide generated after the reaction and residual air enter the converter through the air blower, sulfur dioxide reacts with carbon in the converter through heating of the heating ring, sulfur steam and carbon dioxide are generated, and then a valve is opened; sulfur steam and other gases enter the condenser through the a
