All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, belong to the scope of protection of the present invention.

As shown in fig. 1 to 4, a papermaking felt water spraying device comprises a high-pressure water spraying pipe 1, wherein a plurality of high-pressure nozzles 11 are arranged at intervals on the top of the high-pressure water spraying pipe 1, one end of the high-pressure water spraying pipe 1 is connected with a swing mechanism 2 for driving the high-pressure water spraying pipe to swing in a reciprocating manner, the swing mechanism 2 is an automatic swing device, one end of the automatic swing device is fixed, the other end of the automatic swing device is detachably connected with the end part of the high-pressure water spraying pipe 1, a rotatable cleaning brush 4 is arranged in the high-pressure water spraying pipe 1, and the end part of the cleaning brush 4 is rotatably matched with the other end; the outside of the high-pressure spray pipe 1 is provided with a tug mechanism 5, and the tug mechanism 5 assists the reciprocating motion of the high-pressure spray pipe 1. This papermaking felt water jet equipment installs in the front side of felt 7, and high pressure nozzle 11 aims at the felt, has still seted up the water inlet on the high pressure spray pipe 1 and has connected into water hose 8 through the water inlet, and high pressure water pump (not drawn in the picture) is connected to the hose 8 other end that intakes, and normal washing pressure is 15 ~ 20 bar. When the coarse cotton cloth 7 is not cleaned, the end part of the cleaning brush 4 can be rotated to drive the cleaning brush 4 to integrally rotate to clean the inside of the high-pressure water spray pipe 1 well, so that the problem that the inside of the high-pressure water spray pipe 1 is polluted by dirt after long-term use so as not to clean the coarse cotton cloth 7 well is avoided; the sliding friction of the high-pressure spray pipe 1 during swinging is changed into rolling friction through the tug mechanism 5, so that the damage to the high-pressure spray pipe 1 is reduced, and the high-pressure spray pipe 1 can swing more smoothly; and, the high pressure nozzles 11 at both ends of the high pressure water spraying pipe 1 are more densely arranged, so that the cleaning effect of both ends of the felt 7 is enhanced, and the related production problems caused by the edge contamination of the felt can be reduced.

As shown in fig. 1, the high pressure water spray pipe 1 comprises a pipe body 12 and a sealing flange 13 fixed at the end of the pipe body 12, the high pressure nozzle 11 is arranged on the pipe body 12, the end of the cleaning brush 4 is rotatably connected to the sealing flange 13, and the end of the cleaning brush 4 can be sealed with the sealing flange 13 when being screwed, so that the end of the cleaning brush 4 can be conveniently connected with and detached from the high pressure water spray pipe 1 and can also play a role in sealing the high pressure water spray pipe 1. In addition, can dismantle at the tip of cleaning brush 4 and be connected with hand rim plate 3, specifically, hand rim plate 3 utilizes the screw hole that the tip that the screw rod inserted cleaning brush 4 set up to compress tightly gland axial fixity and connects at the tip that can dismantle cleaning brush 4, utilizes hand rim plate 3 to rotate the tip of cleaning brush 4 for it is more laborsaving more convenient to clean, and the bottom of sealing flange 13 or body 12 still is equipped with drain 6, and in this embodiment, drain 6 is established in the bottom of sealing flange 13, is equipped with blowdown hand valve 61 on the drain 6. When the coarse cotton cloth is not cleaned, the hand wheel disc 3 can be installed at the end part of the cleaning brush 4, the sewage discharge port 6 is opened, the high-pressure water pump is started, the rotary hand wheel disc 3 drives the cleaning brush 4 to rotate, the pipe body 12 of the high-pressure water spray pipe 1 is cleaned by the cleaning brush 4, and sewage is discharged from the sewage discharge port 6. After the inner wall of the high-pressure spray pipe 1 is cleaned by the cleaning brush 4, the high-pressure water pump is closed, the blowdown hand valve 61 is closed, and the end part of the cleaning brush 4 is screwed to seal the sealing flange 13.

As shown in fig. 2 to 4, the cleaning brush 4 includes a brush rod 41 and bristles 42 provided on the brush rod 41, the bristles 42 are rotatably arranged on the brush rod 41 at an angular interval of 120 degrees in the circumferential direction, and the bristles 42 can be kept away from the high pressure nozzle 11 by screwing the cleaning brush 4 to the sealing flange 13 by rotating the end of the cleaning brush 4.
