Abstract
The invention belongs to the technical field of alloy preparing, and particularly relates to a method for preparing silumin powder through coal ash centrifugation to mainly solve the problems that coal ash is wasted seriously, is low in utilization ratio and pollutes the environment. According to the technical scheme and the method for preparing silumin powder through coal ash centrifugation, a centrifugal machine is started to enable the temperature in the centrifugal machine to range from 30 degrees to 40 degrees, a motor is started to drive a screen basket at the lower end of the centrifugal machine to rotate, the coal ash continuously enters the centrifugal machine through a material pushing device and becomes filtering cakes through the centrifugal machine, and the filtering cakes are discharged from a discharge port of the screen basket to be prepared into the silumin powder. The method has the advantages of being simple, friendly to the environment and high in utilization rate.
Description
Technical field
The invention belongs to alloy preparing technical field, be specifically related to a kind of centrifugal method of preparing silicon aluminium alloy powder of flyash of utilizing.
Background technology
There is abundant coalfield in China, and coal is made up of elements such as carbon, silicon, aluminium, calcium, iron, sulphur, titaniums.Many thermal power plants that distributing in China various places, the coal of the varying number that burning every day, is producing the flyash of enormous amount.The composition of flyash is mainly sulfurous acid silicon, aluminium sulfite, calcium oxide etc.Have a large amount of flyash in Shuozhou City god two power plant, these flyash are wasted more, and utilization rate is low, has also caused 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, and a kind of centrifugal method of preparing silicon aluminium alloy powder of flyash of utilizing is provided.
The present invention addresses the above problem the technical scheme of taking to be:
A kind of centrifugal method of preparing silicon aluminium alloy powder of flyash of utilizing, opening centrifuge, to make temperature in centrifuge be 30～40 degree, opening motor rotates with the basket that drives centrifuge lower end, flyash enters centrifuge continuously by pusher, after centrifuge, become filter cake, 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 liquid level gauge 1/2～2/3, and motor current is less than 40 peaces.
The present invention adopts technique scheme, the flyash of power plant is carried out to secondary utilization and produce silicon aluminium alloy powder, for a new direction has been opened up in coal ash secondary utilization, has also reduced the pollution of environment simultaneously.
