The application relates to the technical field of
inorganic compound equipment, in particular to a
rotary kiln system for producing
vanadium pentoxide, which comprises a
rotary kiln body, a supporting mechanism is arranged on one side of the
rotary kiln body, a sealing mechanism is movably installed on one side of the rotary
kiln body, and a gas conveying
pipe is connected to one side of the sealing mechanism; the rotary
kiln system can be stably supported by the positioning rod, the
rotating drum, the nut and the rollers, the
rotating drum is movably sleeved on the positioning rod and is fixed and positioned with the nut, the rollers are distributed in a circumferential array mode at the bottom of the rotary
kiln body, the roller is in contact with the rotary kiln body, the rotation of the rotary kiln body is supported through rolling friction, and the resistance is greatly reduced compared with sliding friction. Meanwhile, the
rotating drum is matched with the positioning rod to limit the
axial displacement of the positioning ring, the convex block is combined with the clamping groove to limit the
radial displacement, and the effect that the device can stably support the rotary kiln body to rotate, reduce the running resistance and improve the stability of the supporting structure is achieved.
