Problems solved by technology

Usually rotary kiln roasting is continuous production, while the existing acid leaching method is single tank leaching (such as figure 1 shown), in order to match the production rhythm of the roasting rotary kiln, more than 30 tanks need to be leached in a single shift. Therefore, the existing leaching method is labor-intensive and difficult to manage

Abstract

The invention relates to vanadium oxide production equipment and discloses a continuous acid leaching device. The continuous acid leaching device comprises supports, a rotary cylinder and a driving mechanism, wherein the rotary cylinder is horizontal, the supports are arranged at two ends of the rotary cylinder, two ends of the rotary cylinder are connected with shaft barrels, material holes communicated with the rotary cylinder are formed in the shaft barrels, bearings are arranged on the supports, the shaft barrels are mounted on the supports through the bearings, and the driving mechanism is in driving connection with the rotary cylinder; a feeding end and a discharging end are arranged at two ends of the rotary cylinder, a feeding main pipe is arranged at the feeding end, a discharging main pipe is arranged at the discharging end, the feeding main pipe and the discharging main pipe are connected with the corresponding shaft barrels though rotary seal rings respectively, and a discharging control valve is mounted on the discharging main pipe. The continuous acid leaching device can cooperates with continuous roasting of a rotary kiln for production, so that operation is simplified, and the production efficiency is improved.

Description

technical field [0001] The invention relates to production equipment of vanadium oxide, in particular to an acid leaching vanadium extraction device after calcification and roasting. Background technique [0002] Vanadium is an important non-ferrous metal, which is widely used in metallurgy, chemical industry, atomic energy and aviation and other fields. At present, vanadium extraction processes include sodium roasting-water leaching vanadium extraction, blank roasting-low-acid vanadium extraction, and calcification roasting-sulfuric acid leaching, etc. Among them, sodium roasting-water leaching vanadium extraction is the most widely used, its technology is mature, the equipment is simple, and the investment is less, but it will form Cl after roasting. 2 , HCl and other harmful gases, the leaching residue contains a large amount of sodium salt, direct backfilling will cause harm to the soil; blank roasting-low-acid vanadium extraction has high requirements for ore raw mater...
