Then the telescopic end of the vertical electric push rod 71 drives the connecting plate 72 and the annular push rod 73 to move downwards, and simultaneously, each compressed elastic piece 61 is initially formed, and simultaneously, the outer edge of the annular film 6 is pushed to expand outwards, so that the distance between the outer edge of the annular film 6 and the inner wall of the kettle body 2 is reduced, at the moment, the annular push rod 73 is kept close to the lower side of the outer edge of the annular film 6, all parts of the outer edge of the annular film 6 are located at the same horizontal height, meanwhile, the output shaft of the motor 54 drives the rotating shaft 55 to rotate, the rotating shaft 55 drives the diverter valve 53 to rotate for one hundred eighty degrees, and the diversion grooves 531 are communicated with the lower areas of the connecting pipe 51 and the annular pipe 4.
And then adding an anti-sticking agent into external steam conveying equipment, conveying the anti-sticking agent to the lower area of the annular pipe 4 along with high-temperature steam by the external steam conveying equipment, filling the whole annular pipe 4 with the high-temperature steam carrying the anti-sticking agent, spraying the high-temperature steam downwards to the middle area of the annular film 6 from a lower nozzle 43, arranging the lower nozzle 43 into a transversely wide and vertically narrow flat nozzle structure, spraying the high-temperature steam and the anti-sticking agent on the annular film 6, preventing part of sprayed high-temperature steam from directly escaping upwards without contacting the annular film 6, and enabling the anti-sticking agent sprayed on the annular film 6 to accumulate in the middle area of the annular film 6 along with moisture in the high-temperature steam, and enabling the rest of moisture high-temperature steam to leave the annular film 6 upwards, so that part of high-temperature steam is kept covered in the kettle body 2, and keeping the inside of the kettle body 2 in a high-temperature state.
Along with the liquid level of the anti-sticking agent accumulation in the middle area of the annular film 6 rises, the anti-sticking agent overflows outwards from the edge area of the annular film 6, overflowed anti-sticking agent flows into a gap between the edge area of the annular film 6 and the inner wall of the kettle body 2 and is adhered to the inner wall of the kettle body 2, meanwhile, the lifting cylinder 12 synchronously drives the fixed ring 3 to move downwards, and the fixed ring 3 drives the annular tube 4, the annular film 6 and the rotary slag scraping mechanism to move downwards, so that the anti-sticking agent overflowed from the edge area of the annular film 6 can be uniformly coated on the inner wall of the kettle body 2 in the downward moving process.
Through this processing step, even if the blocking phenomenon occurs to different degrees in each lower nozzle 43 of the annular tube 4, the liquid level of the anti-sticking agent accumulated in the middle area of the annular film 6 can be kept flush everywhere, so that the anti-sticking agent can uniformly finish the coating work on the inner wall of the kettle body 2 in an overflow manner.
The foregoing is merely exemplary of the present invention and is not intended to limit the present invention. All equivalents and alternatives falling within the spirit of the invention are intended to be included within the scope of the invention. What is not elaborated on the invention belongs to the prior art which is known to the person skilled in the art.
