Abstract

A liquid slag granulating system includes a granulator (1), a granulator connecting part and a granulator drive part. The granulator (1) is disc-shaped or cup-shaped, and a diversion cone is arranged at a center of the granulator (1). The granulator drive part drives the granulator to rotate, thus granulating liquid slag. The system further includes an air supply part.

First claim

What is claimed is:

1. A liquid slag granulating system, comprising a granulator ( 1 ), a granulator connecting part, a motor ( 10 ) and an air supply part, wherein:
the granulator ( 1 ) is disc-shaped or cup-shaped, a diversion cone ( 2 ) is arranged at a center of the granulator, fins ( 13 ) are arranged between the diversion cone and an outer edge of the granulator;
the granulator ( 1 ) is connected with the motor ( 10 ) through the granulator connecting part, the motor ( 10 ) is configured to drive the granulator ( 1 ) to rotate through the granulator connecting part so as to granulate liquid slag which flows into the granulator ( 1 ) into droplets;
the air supply part comprises an air duct outer sleeve ( 7 ) and an air duct inner sleeve ( 8 ) coaxially aligned with the air duct outer sleeve 7 both of which are different from each other in outer diameter, a shaft sleeve ( 9 ) is fixed with the air duct inner sleeve ( 8 ) through an annular end cover ( 5 ) at a bottom of the shaft sleeve ( 9 ); an annular air port ( 11 ) is provided at a top portion of the air supply part.

2. The liquid slag granulating system, as recited in claim 1 , wherein: the annular air port ( 11 ) is located at an outer periphery of the granulator ( 1 ), an air-out angle between an air-out direction of the annular air port ( 11 ) and a horizontal plane is in a range of 15 to 60 degrees.

3. The liquid slag granulating system, as recited in claim 1 , wherein: the annular air port ( 11 ) is located below an outer edge of the granulator.

4. The liquid slag granulating system, as recited in claim 1 , wherein: the shaft sleeve has cooling air holes ( 15 ) at two sides of the two thrust bearings ( 4 ).

5. The liquid slag granulating system, as recited in claim 1 , wherein: the granulator connecting part comprises a granulator base ( 2 ), a shaft ( 3 ) and two thrust bearings ( 4 ); the granulator ( 1 ) is fixedly connected with the granulator base ( 2 ), the granulator base ( 2 ) is fixedly connected with the shaft ( 3 ), the shaft ( 3 ) is fixed with a shaft sleeve ( 9 ) through the two thrust bearings ( 4 ) and simultaneously connected with the motor ( 10 ) through a coupling ( 14 ).

6. The liquid slag granulating system, as recited in claim 1 , wherein: an angle between an outer edge of an upper surface of the granulator ( 1 ) and a horizontal plane is in a range of 15 to 60 degrees.
