6. The equipment for preparing the high-hardness coating on the surface of the stainless steel shell for the nuclear fuel, according to claim 5, is characterized in that a vertical pipe (23) is fixedly connected to the lower wall of the empty tray (22), a piston plate (28) is slidably connected to the inner wall of the vertical pipe (23), a plurality of through holes (29) are formed in the piston plate (28), an electromagnet (30) is fixedly connected to the inner top wall of the vertical pipe (23), and the electromagnet (30) can generate magnetic attraction force on the piston plate (28) when being electrified.
7. The equipment for preparing the high-hardness coating on the surface of the stainless steel shell for the nuclear fuel, according to claim 6, is characterized in that the electromagnet (30) is electrified when the metal ball (27) is contacted with the conductive ring (25), the lower wall of the vertical pipe (23) is fixedly connected with two conductive rings (31) which are not contacted with each other, the piston plate (28) moves downwards to be contacted with the two conductive rings (31), and the electromagnetic valve is electrified and conducted when the piston plate (28) is contacted with the conductive rings (31).
8. The preparation method of the high-hardness coating on the surface of the stainless steel shell for the nuclear fuel is characterized by comprising the following steps of:
s1 preparing material
Pouring the raw materials for preparing the coating into a raw material barrel for later use;
s2, feeding
One end of the feeding pipe (6) far away from the mixing bin (2) is connected with the raw material barrel, the outer motor (3) is started to drive the driving disc (4) to rotate, the driving disc (4) transmits power to the outer disc (7) through the output disc (14), and therefore the feeding blades rotate to pump the raw materials into the mixing bin (2);
s3, mixing
After the raw materials are sent into the mixing bin (2), an inner motor (16) is started, and the inner motor (16) drives a stirring blade (18) to rotate so as to stir and process the raw materials;
s4, discharging
And automatically opening the electromagnetic valve after the raw materials are mixed, allowing the prepared coating to flow out through the electromagnetic valve, and continuing to prepare the coating of the next batch.
