Adjustable material collection device for rotary kiln

Abstract

The invention provides an adjustable material collection device for a rotary kiln. The adjustable material collection device for the rotary kiln is simple in structure and capable of effectively recycling resources, and facilitates discharging of iron slag. The rotary kiln comprises a rotary kiln body and a kiln head hood body. The rotary kiln body is provided with a feed port and a discharge port. The material collection device comprises a collection bin and a conveyor belt. The collection bin is in a funnel shape with a big top and a small bottom. The conveyor belt is arranged below the collection bin. The collection bin is arranged below the discharge port of the rotary kiln body. The conveyor belt is arranged below the collection bin. A plurality of grid bars are evenly distributed at a bin opening of the collection bin and movably connected to the bin opening of the collection bin through connecting rods. Each connecting rod is provided with a sleeve. The sleeves are located between adjacent grid bars. The orientation of the grid bars is consistent with that of the axis of the rotary kiln body. The adjustable material collection device improves the working efficiency and is convenient and fast to use.

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...

AI Technical Summary

Problems solved by technology

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 utilization of resources

[0003] At the same time, it cannot meet the size specifications of the iron slag according to the processing requirements, and cannot be discharged effectively and reliably.
