Description
The utility model relates to a kind of converter steelmaking slag treatment device, particularly a kind of converter steelmaking slag granulation device.
At present, both at home and abroad to the treatment process of copper smelter slag, mainly be that slag is poured slag pan into or the slag ladle post-tensioning carries out fragmentation, classification, go-on-go to cinder yard with melting of producing in the smelting process, recycling, difficulty of processing is big, and the rate of recovery is low, and need take a large amount of soils, contaminate environment.In March, 1999, China Patent Office disclosed a kind of " converter steelmaking slag granulation device "; the patent No.: 98 2 01735.9, though this device slag treatment technology is improved because the granulation wheel construction is single; subject range is narrow, and granulation efficient is lower.
The purpose of this utility model just is to overcome weak point of the prior art, and a kind of less investment is provided, and floor space is little, wide accommodation, the converter steelmaking slag granulation device that granulation efficient is high.
The purpose of this utility model is to realize like this; it comprises: casing; transmission mechanism; quenching device; water trap; exhaust steam tube; quenching device is taken turns by granulation; housing; dreg nozzle constitutes; the granulation wheel is positioned at housing; link to each other with transmission mechanism outward; housing is fixed on the casing; dreg nozzle is positioned at the top of quenching device housing; exhaust steam tube is equipped with in the top of casing; water trap is positioned at the bottom of casing; water trap is by motion-work wheel; axle; driven wheel; chain rivet; hopper constitutes, and each hopper links together by the chain rivet hinge type, is sleeved on the master then; on the driven wheel; motion-work wheel links to each other with transmission mechanism by axle is outer; the pelletizer lower part of frame, the top of water trap is provided with the fluidisation overflow groove, and the side of fluidisation overflow groove is provided with the slide cinder notch.The purpose of this utility model also can realize by following technical measures; the bottom of casing is provided with dreg nozzle and slag removing hole; the granulation wheel construction is a hollow water-cooled; profile can be wolf's fang clavate, W shape, cydariform; equipped high-pressure water pipe on the quenching device; casing is provided with access opening, and water trap motion-work wheel end is provided with tightening device.
The utlity model has following advantage compared to existing technology:
1. simple in structure, use installation and maintenance convenient;
2. less investment, floor space is little, and power consumption is low;
3. wide accommodation;
4. labour intensity is low, granulation efficient height;
