s1, injecting a praseodymium neodymium chloride solution into a reaction kettle 11 through a praseodymium neodymium chloride solution input pipe 14, heating the mixed solution through heating equipment on the inner wall of the reaction kettle 11, then injecting an ammonium bicarbonate solution into the reaction kettle 11 through an ammonium bicarbonate solution input pipe 15, sealing an opening at the top of a collecting net cylinder 32 by an inner sealing block 42 and an outer sealing block 43 at the moment, and stopping the mixed solution at the tops of a guide hopper 31, the inner sealing block 42 and the outer sealing block 43;
s2, reacting the praseodymium neodymium chloride solution with an ammonium bicarbonate solution to generate a precipitate, aging and placing the mixed solution, driving the driving motor 23 to drive the driving shaft 21 to rotate clockwise through the driving gear 24 and the driven gear 22, driving the first threaded sleeve 54 to ascend when the driving shaft 21 rotates clockwise, further driving the screw 44 to rotate when the first threaded sleeve 54 drives the second threaded sleeve 56 to ascend through the side rod 55 and the second threaded sleeve 56 to ascend, and further driving the outer sealing block 43 and the inner sealing block 42 to ascend along the driving shaft 21 by the screw 44;
s3, when the inner sealing block 42 and the outer sealing block 43 ascend, the top opening of the collecting net cylinder 32 is opened, mixed liquid and sediments enter the collecting net cylinder 32 through the top opening of the collecting net cylinder 32, the mixed liquid passes through the collecting net cylinder 32 and flows to the top of the partition plate 12, then the mixed liquid is discharged through the mixed liquid output pipe 16, the sediments are remained on the inner side of the collecting net cylinder 32, when the inner sealing block 42 and the outer sealing block 43 ascend, the driving shaft 21 drives the inner sealing block 42 to rotate through the sliding plate 41, and the sediments remained on the top of the inner sealing block 42 are thrown outwards and further slide into the collecting net cylinder 32;
s4, after the mixed liquid is completely output, the driving motor 23 drives the driving shaft 21 to rotate anticlockwise, water is supplied to the inside of the driving shaft 21 through the washing water input pipe 61, the first threaded sleeve 54 is driven to descend when the driving shaft 21 rotates anticlockwise, the first threaded sleeve 54 drives the compressed first spring 53 to reset in the descending process, the water in the driving shaft 21 enters the washing branch pipes 63 through the connecting transverse pipe 62, then is sprayed to sediments to wash the sediments, meanwhile, the driving shaft 21 drives the collecting net barrel 32 to synchronously rotate through the connecting transverse pipe 62, and then the collecting net barrel 32 centrifuges the washing water and the sediments on the inner side of the collecting net barrel 32, so that the washing water which is washed quickly passes through the collecting net barrel 32 and is discharged;
s5, when the top of the collecting net cylinder 32 is closed again by the inner sealing block 42 and the outer sealing block 43, the output of the washing water is stopped, hot air is input into the driving shaft 21 by the hot air output pipe 71, the hot air enters the sealing cover 73 through the air hole 72, and then is sprayed to the sediment from the opening at the bottom of the extension pipe 74, so that the sediment is dried, in the drying process, the driving shaft 21 continuously drives the collecting net cylinder 32 to rotate, and simultaneously continuously drives the first threaded sleeve 54 to descend, and when the first threaded sleeve 54 descends, the side rod 55 continuously drives the second threaded sleeve 56 to descend, but at the moment, the inner sealing block 42 and the outer sealing block 43 cannot continuously descend, so that the screw 44 cannot rotate, that is, the second threaded sleeve 56 cannot rotate, and the side rod 55 cannot drive the second threaded sleeve 56 to descend, but compresses the second spring 57;
s6, as the first threaded sleeve 54 continuously descends, the reset first spring 53 drives the sealing seat 51 to be separated from the bottom of the collecting net cylinder 32, at the moment, the dried sediment slides along the inclined surface at the top of the sealing seat 51, and then slides to the sediment output pipe 18 through the guide table 13 to be output.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
