2o
3in be heated volatile impurity and dust etc., so that the leaching yield of operation zinc oxide after improving, this just need to pass through purification process, mostly adopt at present box stoving oven purification secondary zinc oxide raw material to have following several respects problem: one, to be heated inhomogeneous, purification efficiency is low, need staff many, labour intensity is large; Two, coal consumption is large, energy expenditure is too high; Three, equipment power consumption is high.
Utility model content
The utility model is in order to solve existing several respects problem in prior art, and the utility model provides a kind of stoving oven of purifying for crude zinc oxide materials impurity elimination of efficient, energy-conservation, power saving.
The technical solution of the utility model is: described stoving oven comprises blanking device, the cylinder being obliquely installed, be positioned at the dust hood of the top, exit of blanking device, described cylinder two ends are provided with opening for feed and discharge port, the exit of described blanking device is near the opening for feed of cylinder, described cylinder is supported by least two supporting-point roller, described supporting-point roller is arranged on roller, roller is arranged on the pedestal of blanking device same level, on described cylinder, be fixedly installed driving gear, described driving gear is meshed with driving toothed gear, driving toothed gear is connected with motor by speed reduction unit, described cylinder middle part is provided with roasting kiln, on roasting kiln, be provided with coal-fired charging opening, on roasting kiln, be provided with smoke exhaust pipe.
The utility model can make secondary zinc oxide raw material dispersed heat abstraction impurity and the dust of being subject in cylinder at short notice, and only need a staff just can operate, not only alleviate labour intensity and improved secondary zinc oxide refining effect and working efficiency, and saved coal consumption and current consumption, reduce production cost.
