Aggregate device of rotary kiln

Abstract

The utility model discloses an aggregate device of a rotary kiln, and relates to the aggregate device of the rotary kiln which is simple in structure, is capable of effectively recycling resources and preparing the residual slag of second zinc oxide by collecting raw materials including iron-making blast furnace flue dust, zinc smelting tailings and the like. A rotary kiln body is provided with a feeding hole and a discharge hole, the aggregate device is arranged below the discharge hole of the rotary kiln and comprises an aggregate bin and a transmit device, wherein the aggregate bin is in a funnel shape which is of big top and small bottom, and the transmit device is arranged below the aggregate bin. The aggregate device is arranged below the rotary kiln body, so that the residual slag can be effectively collected, resources can be further utilized, sold or processed. When the process of the discharge hole of the rotary kiln is completed, the slag and the like can be discharged, and then can be conveniently integrated through the aggregate bin and the transmit device; furthermore, grid rods are uniformly distributed at the upper part of the aggregate bin, in order to prevent the slag with larger volume from mingling and conveniently classify. The aggregate device of the rotary kiln is convenient and fast to use and is capable of improving the working efficiency.

Description

technical field [0001] The invention relates to a collecting device, in particular to collecting iron slag and other raw materials such as iron smelting blast furnace flue ash, zinc smelting tailing slag and the like for preparing secondary zinc oxide residue. Background technique [0002] With the continuous growth of market demand for active zinc oxide and the continuous increase of production costs, as well as the continuous reduction of sub-zinc oxide resources produced in smelting copper and zinc. Some manufacturers have begun to use cheaper ironmaking blast furnace ash to produce secondary zinc oxide. Ironmaking blast furnace ash raw materials contain a large amount of iron and manganese (the iron content is generally 25%, and the manganese content is generally 0.3%). In the prior art, when the iron and manganese in the raw materials are removed, the iron slag formed has no special collection device and can be placed randomly, which is not conducive to the subsequent u...
