Abstract
The invention belongs to field of alloy preparation technology, be specifically related to a kind ofly utilize the centrifugal method preparing silicon aluminium alloy powder of flyash.The present invention mainly solves that flyash waste is serious, utilization rate is low and the problem of contaminated environment.Technical scheme of the present invention is: a kind ofly utilize the centrifugal method preparing silicon aluminium alloy powder of flyash, opening centrifuge makes the temperature in centrifuge be 30 ~ 40 degree, open motor to rotate to drive the basket of centrifuge lower end, flyash enters centrifuge continuously by pusher, after centrifuge, become filter cake, namely filter cake out makes silicon aluminium alloy powder through basket from discharging opening.The present invention has that method is simple, environmental protection and the high advantage of utilization rate.
Description
Technical field
The invention belongs to field of alloy preparation technology, be specifically related to a kind ofly utilize the centrifugal method preparing silicon aluminium alloy powder of flyash.
Background technology
There is abundant coalfield in China, and coal is made up of elements such as carbon, silicon, aluminium, calcium, iron, sulphur, titaniums.Be dispersed with many thermal power plants in China various places, be burning the coal of varying number every day, produce the flyash of enormous amount.Composition mainly sulfurous acid silicon, aluminium sulfite, the calcium oxide etc. of flyash.Have a large amount of flyash in Shuozhou City god two power plant, these flyash are wasted more, and utilization rate is low, also result in certain environmental pollution.
Summary of the invention
The present invention is serious mainly for flyash waste, utilization rate is low and the problem of contaminated environment, provides a kind of and utilizes the centrifugal method preparing silicon aluminium alloy powder of flyash.
The present invention is the technical scheme taked that solves the problem:
A kind ofly utilize the centrifugal method preparing silicon aluminium alloy powder of flyash, opening centrifuge makes the temperature in centrifuge be 30 ~ 40 degree, open motor to rotate to drive the basket of centrifuge lower end, flyash enters centrifuge continuously by pusher, after centrifuge, become filter cake, namely filter cake out makes silicon aluminium alloy powder through basket from discharging opening;
One end of wherein said basket is by blast pipe gravity-flow ventilation, and the other end of basket is collected tail gas by blow-down pipe and carried out conventional dry method or wet desulphurization;
The reciprocal time of described pusher is 20 ~ 25 beats/min, and the stroke of pusher is 35 ~ 40 millimeters;
Described motor pump outlet oil pressure is 8 ~ 16 kilograms, and oil sump temperature is less than 60 degree, and oil groove oil level is 1/2 ~ 2/3 of liquid level gauge, and motor current is less than 40 peaces.
The present invention adopts technique scheme, the flyash of power plant is carried out secondary and utilizes and produce silicon aluminium alloy powder, open a new direction, decrease the pollution of environment simultaneously for coal ash secondary utilizes.
