[0063] The working principle of the embodiment is described in detail as follows: Paper pulp impurity removal process: The paper pulp enters the machine body 1 through the material inlet 101, and the stirring shaft 11 rotates to separate the impurities and the paper pulp.

[0064] The pulp enters the pulp channel 103 through the filter holes 21 on the lower side of the filter cylinder 2, and is discharged from the machine body 1. The impurities are intercepted by the filter holes 21 and finally discharged from the material outlet 102.

[0065] During the separation process, the water pipe 12 sprays water into the machine body 1 to prevent the pulp from adhering to the stirring shaft 11. The clean water is mixed with the pulp and then discharged from the pulp channel 103.

[0066] Filter hole cleaning process: The telescopic part 31 pushes the top plate 3 upwards away from the mounting groove. During the upward movement of the top plate 3, the first rack 32 drives the first gear 22 to rotate, and the first gear 22 drives the filter cylinder 2 to rotate through the gear ring 23, so that the filter holes 21 are directed upwards.

The water in the water pipe 12 enters the arc-shaped water spray pipe 41 through the transverse channel 35.

[0068] After the water enters the water inlet channel 43, the water flow drives the blade 433 to rotate, drives the second sprocket 434 to rotate through the rotating shaft 432, drives the two first sprockets 421 to rotate through the chain 422, and drives the moving wheel 423 to rotate through the conical gear transmission, so that the arc-shaped sliding seat 4 slides horizontally along the mounting groove.

[0069] The several nozzles of the arc-shaped water spray pipe 41 are aligned with the filter holes 21, and each filter hole 21 is washed one by one to ensure that each filter hole 21 can be thoroughly cleaned.

[0070] When the arc-shaped sliding seat 4 slides to the left end of the mounting groove, the left end of the sliding rod 44 abuts against the side wall of the mounting groove, pushes the sliding rod 44 to slide, and makes the connecting part 441 and the connected part disengage, so that the rotating shaft 432 no longer drives the second sprocket 434 to rotate, and the moving wheel 423 loses power.

[0071] The reset spring of the coil spring drives the winding disc 45 to rotate, winds the pull line, and pulls the arc-shaped sliding seat 4 to slide to the right until it returns to the storage groove 33. The right end of the sliding rod 44 abuts against the side wall of the storage groove 33, so that the connecting part 441 and the connected part are reconnected, and the arc-shaped sliding seat 4 realizes reciprocating motion in the mounting groove to continuously clean the filter holes.

[0072] Device reset: After the cleaning is completed, the water supply to the water pipe 12 is stopped, and under the action of the winding disc 45, the arc-shaped sliding seat 4 is located in the storage groove 33, the top plate 3 moves downward to retract the installation groove, the end of the top rod 384 abuts against the inclined surface of the side wall of the installation groove, the top rod 384 is pushed to slide, the second rack 382 is reversely rotated, the blocking block 37 is rotated, the transverse channel 35 is re-blocked, the longitudinal channel 34 is opened, and the clean water of the water pipe 12 enters the machine body 1 again through the longitudinal channel 34, so that the paper pulp impurity separation process is restored.

[0073] Other embodiments; As a further improvement of the above-mentioned embodiments, the arc-shaped sliding seat 4 is further provided with a knocking assembly, the knocking assembly comprises a plurality of third sprockets 5 rotatably installed in the arc-shaped groove 42, the plurality of third sprockets 5 are all engaged with the chain 422, when the arc-shaped sliding seat 4 moves, the chain 422 will move, driving the plurality of third sprockets 5 to move synchronously, the plurality of third sprockets 5 are all connected with knocking blocks 51, the knocking blocks 51 rotate to knock the filter cylinder 2, so that the filter cylinder 2 vibrates, the impurities attached to the filter cylinder 2 are vibrated off, cooperating with the clean water flushing, so that the cleaning effect of the filter hole 21 is further improved.

[0074] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered in the scope of the claims and the specification of the present application.
