The inclined wire papermaking machine is a type of papermaking machine, and the central pulp distributor is a part of the inclined wire papermaking machine. It is a device that ensures that the pressure of the pulp entering the headbox is uniform across the entire width of the headbox.

[0003] During use of the existing central pulp distributor, in order to ensure that the pulp entering the headbox has uniform pressure across the entire width in the headbox, the pulp is transported through multiple pipes. After each use, the central pulp distributor needs to be cleaned internally to prevent residual solidified pulp from affecting the next pulping operation. When cleaning the existing central pulp distributor, the central pulp distributor is disassembled in order to be able to clean the dead corners inside it. However, the central pulp distributor is fixed and locked with bolts at the joints with the top cover and the pipes.

The end of the connecting swivel 208 located at one end of the first arc-shaped slide groove 202 is provided with a connecting slot 2011 that matches the outer wall of the positioning plug shaft 2010. The outer wall of the positioning plug shaft 2010 is provided with an annular groove. The inner wall of the first arc-shaped slide groove 202 is formed with a limiting strip 201 that fits with the inner wall of the annular groove. The first arc-shaped slide groove 202 is used for sliding connection between the connecting swivel 208 and the positioning plug shaft 2010.

[0040] The locking assembly includes: a plurality of guide shafts 204 circumferentially equidistantly formed on the outer wall of the pulp distributor body 1, the outer wall of the guide shaft 204 is sleeved with a movable plate 205 that contacts the outer wall of the discharge pipe 7 and the connecting swivel 208, one end of the movable plate 205 is formed with a locking block 209 that contacts the upper surface of the first docking ring 303 and the second docking ring 304, the top of the movable plate 205 is fixedly connected to the connecting shaft 206, and a second arc-shaped slide groove 207 is provided at the connection position between the connecting swivel 208 and the connecting shaft 206, and the locking block 209 is used to block and fix the second docking ring 304.

[0041] In this embodiment: by suspending the top cover 4 and placing it directly above the pulp distributor body 1, and then pulling the top cover 4 down to contact the upper surface of the pulp distributor body 1, during this process, the positioning shaft 2010 is pushed by the top cover 4, penetrates the pulp distributor body 1 and is inserted into the interior of the connecting slot 2011, so that the positioning shaft 2010 can be conveniently connected with the connecting swivel 208, and then the pre-docking of multiple discharge pipes 7 and feed pipes 8 can be achieved through the docking mechanism 3.

[0042] Then, the connecting ring 208 is rotated along the outer wall of the fixed ring 203. At this time, the first arc-shaped slide groove 202, driven by the connecting ring 208, drives the limiting strip 201 to move along the outer wall of the positioning plug shaft 2010. The limiting strip 201 limits the positioning plug shaft 2010, so that the top cover 4 can be conveniently fixed.

[0043] At the same time, the second arc-shaped slide groove 207 moves driven by the connecting swivel 208. At this time, the connecting shaft 206, driven by the second arc-shaped slide groove 207, pushes the outer wall of the locking block 209 to move along the guide shaft 204 through the movable plate 205 until the movable plate 205 is blocked by the limit baffle. At the same time, the locking block 209 moves to the upper surface of the first docking ring 303 and the second docking ring 304, blocking the second docking ring 304, thereby realizing convenient locking of the discharge pipe 7 and the feed pipe 8.

[0044] Then rotate the bolt to pass through the positioning plate 6 and threadedly connect it to the connecting ring 208, so as to lock and fix the connecting ring 208. When it is necessary to clean or maintain the interior of the pulp distributor body 1, the above operation is reversed to further improve the cleaning efficiency of the pulp distributor body 1.

[0046] In this embodiment, the second docking ring 304 can be precisely plugged into the positioning plug block 302 through the square platform-shaped outer wall, so as to facilitate the pre-docking of the first docking ring 303 and the second docking ring 304 .

[0047] A connecting sleeve groove that matches the outer wall of the guide shaft 204 is provided at the connecting position of the movable plate 205 and the guide shaft 204 . A limit baffle is formed on the end of the guide shaft 204 away from the pulp distributor body 1 for blocking the movable plate 205 .

[0048] In this embodiment, through the cooperation between the connecting sleeve and the limit baffle, the movable plate 205 can move along the outer surface of the guide shaft 204 under the guidance of the second arc-shaped sliding groove 207 through the connecting shaft 206 until the movable plate 205 is blocked by the limit baffle.

[0049] The working principle of the present invention is as follows: It is particularly important to note that the pulp distributor body 1 includes a feed pipe 5, a damper, a multi-tube pulp distribution chamber, and the connection between the discharge pipe 7 and the feed pipe 8. The pulp distributor body 1 is designed based on isobaric theory to ensure that the pulp entering the headbox has uniform pressure across the entire width of the headbox. The diameter and number of the pulp inlet pipes are determined based on the amount of sizing to ensure the accuracy of the amount of sizing applied to the screen. The pulp distributor is welded from 5mm thick 304 stainless steel plate, and the inner wall is polished to a roughness of ≤0.4. A cotton ball should be used to check that no cotton fibers are caught.

[0050] When using this device, the top cover 4 is suspended and placed directly above the pulp distributor body 1, and then the top cover 4 is pulled down to contact the upper surface of the pulp distributor body 1. During this process, the positioning shaft 2010 is pushed by the top cover 4, penetrates the pulp distributor body 1 and is inserted into the interior of the connecting slot 2011, so that the positioning shaft 2010 can be easily connected to the connecting ring 208.

[0051] Then, the second docking ring 304 is suspended and placed directly above the positioning plug 302 through a feeding tube 8, and then the feeding tube 8 is pulled to make the second docking ring 304 descend and sleeve the positioning plug 302. During this process, the sealing gasket 301 is deformed under the extrusion of the second docking ring 304, which can make the second docking ring 304 and the first docking ring 303 sealed and pre-docked, so as to achieve pre-docking of the discharge pipe 7 and the feeding pipe 8, and then repeat the operation for multiple discharge pipes 7 and feeding pipes 8 to achieve pre-docking of multiple discharge pipes 7 and feeding pipes 8.

[0052] Then, the connecting ring 208 is rotated along the outer wall of the fixed ring 203. At this time, the first arc-shaped slide groove 202, driven by the connecting ring 208, drives the limiting strip 201 to move along the outer wall of the positioning plug shaft 2010. The limiting strip 201 limits the positioning plug shaft 2010, so that the top cover 4 can be conveniently fixed.

[0053] At the same time, the second arc-shaped slide groove 207 moves driven by the connecting swivel 208. At this time, the connecting shaft 206, driven by the second arc-shaped slide groove 207, pushes the outer wall of the locking block 209 to move along the guide shaft 204 through the movable plate 205 until the movable plate 205 is blocked by the limit baffle. At the same time, the locking block 209 moves to the upper surface of the first docking ring 303 and the second docking ring 304, blocking the second docking ring 304, thereby realizing convenient locking of the discharge pipe 7 and the feed pipe 8.

[0054] Then rotate the bolt to pass through the positioning plate 6 and threadedly connect it to the connecting ring 208, so as to lock and fix the connecting ring 208. When it is necessary to clean or maintain the interior of the pulp distributor body 1, the above operation is reversed to further improve the cleaning efficiency of the pulp distributor body 1.

[0055] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
