Technical Field

The utility model belongs to the hydrometallurgy field, more specifically the tuber pipe device that makes things convenient for high-efficient oxidation of zinc smelting output copper sediment to leach that says so.

Background

In the zinc hydrometallurgy process, according to the difference of the leaching process, 25-90% of copper in the zinc raw material enters copper slag after cadmium is recovered. The copper slag generally contains 10-50% of copper and 2-10% of zinc, copper in the newly produced copper slag mainly exists in the form of simple substance copper and a small amount of cuprous oxide, when the wet copper slag is stacked, the copper reacts with carbon dioxide in the air, and according to the difference of stacking time and stacking mode, part or most of metal copper in the copper slag can be converted into easily leached basic copper carbonate. In order to realize the recycling of the valuable metal copper in the copper slag, a great deal of research work is carried out on the leaching of the copper in the copper slag by mass production and scientific research workers, and various methods are found, wherein the most widely applied method is the atmospheric pressure blast leaching of the copper slag. The air pipe is a core device in the blast leaching process, and the arrangement of the air pipe not only relates to the leaching rate of copper and the leaching time, but also relates to the workload of installation and maintenance. In the traditional view, the leaching efficiency of the porous centrally arranged air pipe on copper is high, but the air pipe is easy to block and difficult to maintain, and the installation and application are difficult to realize in industrialization; therefore, research workers improve the stirring, so that the air pipe and the stirring are unified, but the maintenance and the repair of the air pipe are difficult, and the processing cost is high; in addition, a plurality of points are distributed on one air pipe, so that the air pipe is inconvenient to use and influences the leaching process during maintenance. In view of the unreasonable arrangement of the air ducts, the invention patents 2007103012161 and 2012101361351 both adopt the steps of pre-stacking and oxidizing the copper slag, and then putting the copper slag into a leaching tank for blast leaching, but the stacking and oxidizing have the problems of occupying the site, large workload of transportation, easy environmental pollution, overstocked capital and the like.

Therefore, finding and realizing the air pipe and the air pipe arrangement which are convenient to manufacture and install, easy to maintain and repair, free of stacking and oxidation of copper slag and capable of guaranteeing high leaching rate in direct leaching has very important practical significance.
