TECHNICAL FIELD

[0001] The present application relates to the technical field of papermaking, in particular to a papermaking screen cleaning device. BACKGROUND

[0002] The papermaking screen is a key component in the papermaking process, used to carry the pulp and filter out the water to form a wet paper sheet. During long-term use, the surface of the papermaking screen will accumulate a large amount of fibers, fillers and other impurities. These residues not only block the screen holes, reducing the water filtration efficiency, but also affect the quality of the paper. The traditional cleaning method mainly relies on manual brushing or high-pressure water flushing, but has the following problems:

[0003] Incomplete cleaning: manual operation cannot completely remove the fibers and impurities embedded in the screen holes, resulting in repeated accumulation of residues; low efficiency: high-pressure water flushing can remove some impurities, but water and fibers are easily reattached to the screen surface, causing secondary pollution.

DETAILED DESCRIPTION

[0030] The present application will be further described in detail through specific embodiments. Figures 1-6

[0031] The papermaking screen cleaning device provided by the present application comprises a centralized box 1, the upper end of the centralized box 1 is provided in an open manner, a positioning mechanism 3 is mounted on the upper side of the centralized box 1, the positioning mechanism 3 comprises a mounting bracket 301, a collection roller 302 is rotatably connected to the inner side of the mounting bracket 301, a plurality of hole-shaped structures are formed on the outer side of the collection roller 302, an adhesion cylinder 303 is attached to the outer side of the collection roller 302, so as to avoid the fibers and moisture on the surface of the papermaking screen from being difficult to clean due to the attachment of the collection roller 302 to the surface of the papermaking screen, and the hole-shaped structures on the outer surface of the collection roller 302 and the mesh structure on the outer side of the adhesion cylinder 303 can enable the fibers and moisture to enter the inside of the collection roller 302, thereby avoiding the fibers and moisture from falling back to the other surface of the papermaking screen due to the rapid downward movement caused by gravity;

[0032] One end of the collection roller 302 is connected to the output end of a driving motor 304, the driving motor 304 is mounted on the outer side of the mounting bracket 301, and the driving motor 304 drives the collection roller 302 to rotate actively, so as to enable the collection roller 302 to rotate automatically and clean the surface of the papermaking screen automatically;

[0033] ​The outer side of the positioning mechanism 3 is provided with a cleaning mechanism 4 mounted on the upper end of the collecting box 1, which sprays gas or water to clean the surface of the papermaking net, and the cleaning mechanism 4 comprises a support frame 401, the inner side of the support frame 401 is inclinedly arranged, and a plurality of cleaning pipes 402 are arranged at equal intervals on the upper end of the support frame 401, the cleaning pipes 402 are connected with external air pumps or water pumps, so that the gas or water is discharged, and the outlet of the cleaning pipe 402 is inclined downward, so that the spraying direction of the gas or water is downward, so that part of the fibers and moisture on the surface of the papermaking net can be directly cleaned into the collecting box 1;

[0034] The length of the adhesion cylinder 303 is smaller than the length of the papermaking net, one end of the collecting roller 302 is provided with a clamping mechanism 5 for clamping the part of the papermaking net protruding from the adhesion cylinder 303, the clamping mechanism 5 comprises a mounting ring 501 arranged on the outer side of the connecting shaft of the collecting roller 302, and the mounting ring 501 is rotationally connected with the connecting shaft, a gas cylinder 502 is mounted on the end of the mounting ring 501 away from the adhesion cylinder 303, the gas cylinder 502 drives the mounting ring 501 to move horizontally, a plurality of clamping blocks 503 are slidably connected to the inner side of the mounting ring 501, and the clamping blocks 503 clamp the part of the papermaking net protruding from the adhesion cylinder 303 in cooperation with the mounting ring 501, and an auxiliary ring 504 is fixedly mounted on the end of the collecting roller 302 facing the mounting ring 501, and the contact surfaces of the auxiliary ring 504 and the clamping blocks 503 are both inclinedly arranged;

[0035] Specifically, the gas cylinder 502 is started to drive the mounting ring 501 to move towards the collecting roller 302, so that the clamping blocks 503 are unfolded outward along the inclined outer surface of the auxiliary ring 504, so that the distance between the clamping blocks 503 and the mounting ring 501 is reduced, and then the motor 304 is started to change the contact position between the adhesion cylinder 303 and the papermaking net, so that the contact surface between the adhesion cylinder 303 and the papermaking net has no residual fibers and moisture, and the cleaning of the papermaking net is more thorough, after the clamping mechanism 5 is clamped, the collecting roller 302 rotates for a period of time, and then the clamping mechanism 5 is released, so that the papermaking net is recombined with the adhesion cylinder 303;

[0036] During the cleaning process, the moisture and fibers will move downward due to gravity, so that they finally move circularly on the inner surface of the circumference of the papermaking net, therefore, the circumference of the adhesion cylinder 303 needs to be larger than the width of the papermaking net, so that the papermaking net cannot form a closed loop on the outer surface of the adhesion cylinder 303, so that the moisture and fibers can be discharged from the position where the papermaking net is not closed;

[0037] When the collecting roller 302 rotates for a period, the papermaking net covered on the outer surface of the adhesion cylinder 303 is cleaned, and a small part of fibers may be left. For the remaining fibers, the papermaking net can be manually held at one end, separated from the adhesion cylinder 303, and gradually pulled out, so that the papermaking net is completely separated from the adhesion cylinder 303. In the process of separation, the cleaning pipe 402 continuously works to clean the small part of fibers into the collecting roller 302.

[0038] The inner side of the centralized box 1 is further provided with a separation structure 2, which comprises a filter screen 201, one end of the filter screen 201 is fixed with a handle 202 located outside the centralized box 1. The filter screen 201 can separate the water and fibers cleaned by the cleaning mechanism 4, so that the water flows downward and the fibers are retained on the upper side of the filter screen 201.

[0039] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradiction), in order to make the description simple, not all possible combinations of each technical feature in the above embodiments are described; these embodiments which are not explicitly written should also be considered as the scope of the present application.
