Rotary crystallization kiln for alpha gypsum powder
The invention discloses a rotary crystallization kiln for alpha gypsum powder. The rotary crystallization kiln for alpha gypsum powder comprises a rack, a kiln body, a feeding end, a discharging end, a tail gas collector, a heat supply chamber, a heat exchanging pipe, an inlet end socket, an outlet end socket and a power transmission device, wherein the kiln body and the power transmission device are mounted on the rack; the power transmission device is used for driving the kiln body to rotate on the rack, and when the inlet end socket and the outlet end socket are closed, the kiln becomes an airtight space; and a circle of heat exchanging pipe communicated with the heat supply chamber and having the function of a lifting board is fixed on the inner wall of the kiln body. The rotary crystallization kiln is in a dynamic mode rather than a static mode; the heat exchanging area is increased due to the arrangement of the heat exchanging pipe; heat energy is fully used through multiple technical methods, and therefore, energy consumption is lowered; the functions of pre-drying, autoclaving crystallization and product drying are integrated, the process steps are reduced, the quantity of equipment is lowered, the production time is shortened, and the production cost is lowered; and no external high-temperature steam or aqueous solution participates in heat exchange and reaction, and hemihydrate gypsum is prevented from being hydrated again into dihydrate gypsum, so that the product quality is more stable.
