After slurry is filtered, the upper-layer vibrator 2 and the lower-layer vibrator 3 are closed, the ultrasonic generator 4 is closed, the ultrasonic lifting cylinder 13 works to move the ultrasonic lifting frame 11 upwards for a certain distance, the upper-layer electromagnetic suction fixing ring 10 and the lower-layer electromagnetic suction fixing ring 26 are electrified, the upper-layer electromagnetic suction fixing ring 10 adsorbs the upper-layer screen mesh 25 to enable the upper-layer screen mesh 25 to leave the upper-layer filtering assembly, the lower-layer electromagnetic suction fixing ring 26 adsorbs the lower-layer screen mesh 24 to enable the lower-layer screen mesh 24 to leave the lower-layer filtering assembly, then, the upper-layer lifting cylinder 14 works to drive the upper-layer screen mesh 25 to move upwards to move out of the upper-layer fixing conical ring 5 by moving the upper-layer electromagnetic suction fixing ring 10 upwards, the upper-layer telescopic cylinder 16 works to drive the upper-layer lifting cylinder 14 to move leftwards to drive the upper-layer screen; meanwhile, the lower layer lifting cylinder 20 works to drive the lower layer screen mesh 24 to move upwards out of the lower layer fixed conical ring 6 by moving the lower layer electromagnetic attraction fixing ring 26 upwards, the lower layer telescopic cylinder 21 works to drive the lower layer screen mesh 24 to move to the rear by driving the lower layer lifting cylinder 20 to move backwards, and then the second steering engine 22 works to turn over the lower layer screen mesh 24; then the upper flushing mechanism works to flush the filtered out oversized flaky particles into the upper collecting container 18, the lower flushing mechanism works to flush the filtered rod-shaped and needle-shaped particles into the lower collecting container 23, meanwhile, the charging basket 7 can be moved away from the lower part of the lower fixed conical ring 6, the waste charging basket is replaced, the charging pipe 9 is controlled to open and close through the tee joint to output purified water to flush the upper fixed conical ring 5 and the lower fixed conical ring 6, and residual slurry is removed. After the washing is finished, a first steering engine 17, an upper telescopic cylinder 16 and an upper lifting cylinder 14 of the upper telescopic turnover mechanism work in sequence to drive the upper screen mesh 25 to return to the position above the upper filtering assembly, and the upper electromagnetic suction fixing ring 10 is powered off, so that the upper screen mesh 25 falls into the upper filtering assembly; the second steering wheel 22, the lower telescopic cylinder 21 and the lower lifting cylinder 20 of the lower telescopic turnover mechanism work in sequence to drive the lower screen 24 to return to the upper part of the lower filtering component, and the lower electromagnetic suction fixing ring 26 is powered off, so that the lower screen 24 falls into the lower filtering component and is prepared for next filtering.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
