Abstract

The invention discloses a furnace tube structure of a tungsten-molybdenum calcination or reduction rotary furnace. The furnace tube structure aims to solve the technical problems of large temperaturedifference, unstable product quality and low powder material yield in a furnace tube in existing rotary furnace processing. The furnace tube structure is a double-layer coaxial hollow tubular structure and comprises an inner furnace tube wall and an outer furnace tube wall which are fixedly connected with each other, a feeding opening is formed in one end between the inner furnace tube wall and the outer furnace tube wall, a discharging opening is formed in the other end between the inner furnace tube wall and the outer furnace tube wall, a heating space for tungsten-molybdenum calcination orreduction is formed between the inner furnace tube wall and the outer furnace tube wall, and a plurality of material-blocking rib plates perpendicular to the axial direction are correspondingly and fixedly installed on the inner furnace tube wall and the outer furnace tube wall in the heating space in the axial direction in a uniform distribution mode. According to the furnace tube structure of the tungsten-molybdenum calcination or reduction rotary furnace, an inner furnace tube and an outer furnace tube are heated at the same time, the temperature uniformity and sufficient reaction of powdermaterials are effectively ensured, uniformity and stability of the product quality are ensured, and the powder material yield is improved.

Description

technical field [0001] The invention belongs to the field of tungsten-molybdenum chemical metallurgical treatment equipment, in particular to a furnace tube structure of a tungsten-molybdenum calcining or reduction rotary furnace. Background technique [0002] Rotary furnace is a kind of thermal processing equipment for calcining, roasting or drying granular and powdery materials. It is widely used in various chemical and metallurgical treatments. The characteristic of rotary furnace is that its furnace tube will be connected to a motor to drive its rotation, so it is called It is a rotary furnace; at the same time, according to its different processing needs, the structure of the rotary furnace will also undergo certain changes accordingly. [0003] In the field of tungsten and molybdenum processing, the rotary furnace includes a rotary tube calciner and a rotary tube reduction furnace. The rotary tube calciner can be used to heat and calcinate ammonium paratungstate (or am...
