Description

Technical Field

[0001] This utility model relates to the field of kraft paper production technology, specifically a slag removal device for improving the quality of kraft paper pulp. Background Technology

[0002] Kraft paper has high strength and is usually yellowish-brown. Semi-bleached or fully bleached kraft pulp is light brown, cream, or white. Its basis weight is 80-120 g / m2, and its breaking length is generally over 6000 m. It has high tear strength, bursting energy, and dynamic strength. It is made from sulfate softwood pulp, which is beaten and formed on a fourdrinier paper machine. It can be used as cement bag paper, envelope paper, sealing paper, asphalt paper, cable protection paper, insulating paper, etc. In the production of kraft paper, impurities need to be removed from the pulp to improve its quality.

[0003] Chinese patent CN218026903U discloses a pulp deslagging device for papermaking, including a deslagging box with symmetrically arranged support seats on the bottom side wall of the deslagging box. The support seats are perpendicular to the deslagging box, and a filter box is rotatably connected to the bottom inner wall of the deslagging box. This utility model, through the cooperation of the deslagging box, filter box, arc plate, filter screen, and drive motor, can quickly centrifuge and separate pulp for deslagging. Through the cooperation of the first shaft, second shaft, and dispersing blades, the dispersing blades can be automatically driven to rotate during centrifugal rotation to disperse the pulp, facilitating centrifugal deslagging and improving the centrifugal effect. However, in the above patent, after filtering and deslagging the pulp, impurities remain in the filter box, requiring them to be removed little by little, which is very inconvenient, reduces the removal efficiency, and reduces the practicality of the device. Therefore, we propose a deslagging device to improve the quality of kraft paper pulp. Utility Model Content

[0004] The purpose of this utility model is to provide a slag removal device for improving the quality of kraft paper pulp, so as to solve the problem in the prior art that when the pulp is filtered and slag removed, impurities remain in the filter box and need to be removed little by little, which makes the removal of impurities very inconvenient, reduces the removal efficiency, and reduces the practicality of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slag removal device for improving the quality of kraft paper pulp, comprising a slag removal cylinder, a discharge pipe fixed to the bottom edge of the slag removal cylinder, a conical platform fixed to the bottom center of the inner cavity of the slag removal cylinder, a support column fixed to the bottom of the slag removal cylinder, a drive motor fixed to the bottom center of the slag removal cylinder, an installation cylinder fixed to the end of the output shaft of the drive motor, a filter cylinder connected inside the installation cylinder, a disassembly and assembly mechanism provided on the outside of the filter cylinder, and a scraping mechanism connected to the top of the slag removal cylinder.

[0006] Preferably, the disassembly and assembly mechanism includes mounting blocks symmetrically fixed to the top outer side of the mounting cylinder, a slot extending through the top center of the mounting block, L-shaped rods symmetrically fixed to the top outer side of the filter cylinder, a contraction cavity opening at the bottom of one side of the L-shaped rod, a return spring fixed to the center of one side of the contraction cavity, a connecting plate fixed to one end of the return spring, a locking block fixed to the center of one side of the connecting plate, a pull plate fixed to the center of the top of the connecting plate, and a moving groove extending through the center of the top of the contraction cavity.

[0007] Preferably, the output shaft end of the drive motor passes through the bottom of the inner cavity of the slag removal cylinder and the top of the conical platform.

[0008] Preferably, the length and width of the slot are equal to the length and width of the bottom of the L-shaped rod, which facilitates the outer wall of the L-shaped rod to fit against the inner side of the slot. The bottom of the card block is provided with an inclined surface, which facilitates the pressing of the inclined surface of the card block to move the card block.

[0009] Preferably, the connecting plate slides inside the contraction cavity, and the outer wall of the connecting plate is in contact with the inner wall of the contraction cavity, which facilitates stable movement of the connecting plate, and the pull plate is located inside the moving groove.

[0010] Preferably, the scraping mechanism includes a support rod fixed to the top of the slag removal cylinder, a mounting plate fixed to the top of the support rod, a dual-axis motor fixed to the top center of the mounting plate, a turntable fixed to the end of the output shaft of the dual-axis motor, a connecting rod fixed to one side of the turntable, slide rods symmetrically sliding through the top of the slag removal cylinder, a scraping ring fixed to the bottom end of the slide rod, a moving rod fixed to the top end of the scraping ring, and a square groove through the middle of one side of the moving rod.

[0011] Preferably, the sliding rod passes through the top of the mounting plate, the outer wall of the scraper ring is in contact with the inner wall of the slag removal cylinder to facilitate scraping the inner wall of the slag removal cylinder, the connecting rod is located inside the square groove, and the outer wall of the connecting rod is in contact with the inner wall of the square groove, and the diameter of the turntable is smaller than the length of the square groove to avoid motion interference.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application utilizes a disassembly and assembly mechanism. By pulling the pull plate, the connecting plate is moved, causing the connecting plate to move the locking block. This causes the locking block to retract inside the shrinkage cavity, thereby releasing the obstruction of the mounting block on the locking block. Pulling the filter cylinder allows for the complete disassembly of the filter cylinder, making it easier to remove all the filter residue inside. This makes removal simpler and more convenient, saving time and effort, and improving the practicality of the device.

[0014] 2. In this application, the scraping mechanism is designed to drive the turntable to rotate by starting a dual-axis motor, which causes the connecting rod to move in a circular motion. This causes the connecting rod to squeeze the side wall of the square groove, which in turn causes the moving rod to move up and down. This causes the sliding rod to move the scraper ring up and down, scraping the side wall of the slag removal cylinder. This facilitates the scraping of the pulp, allowing the pulp to fall quickly, improving the discharge efficiency and reducing residue. Attached Figure Description

[0023] Please see Figure 2 , Figure 3 and Figure 4 The disassembly and assembly mechanism 400 includes mounting blocks 410 symmetrically fixed to the top of the outer side of the mounting cylinder 310. A slot 420 is provided through the center of the top of the mounting block 410. An L-shaped rod 430 is symmetrically fixed to the top of the outer side of the filter cylinder 600. A contraction cavity 440 is provided at the bottom of one side of the L-shaped rod 430. A return spring 450 is fixed to the center of one side of the contraction cavity 440. A connecting plate 460 is fixed to one end of the return spring 450. A locking block 470 is fixed to the center of one side of the connecting plate 460. A pull plate 480 is fixed to the center of the top of the connecting plate 460. A moving groove 490 is provided through the center of the top of the contraction cavity 440. The output shaft end of the drive motor 300 passes through the bottom of the inner cavity of the slag removal cylinder 100 and the top of the conical platform 120. The length, width, and L of the slot 420 are... The bottom of the rod 430 has equal length and width, and the bottom of the locking block 470 is provided with an inclined surface; the connecting plate 460 slides inside the shrinkage cavity 440, and the outer side wall of the connecting plate 460 is in contact with the inner side wall of the shrinkage cavity 440; the pull plate 480 is located inside the moving groove 490; by using the disassembly and assembly mechanism 400, by pulling the pull plate 480, the connecting plate 460 is moved, which causes the connecting plate 460 to move the locking block 470, so that the locking block 470 retracts inside the shrinkage cavity 440, thereby releasing the obstruction of the mounting block 410 on the locking block 470, pulling the filter cylinder 600, and disassembling the filter cylinder 600 as a whole, so that all the filter residue inside the filter cylinder 600 can be easily removed, making removal simpler and more convenient, saving removal time and effort, and improving the practicality of the device.

[0024] Please see Figure 5The scraping mechanism 500 includes a support rod 510 fixed to the top of the slag removal cylinder 100. A mounting plate 520 is fixed to the top of the support rod 510. A dual-axis motor 530 is fixed to the middle of the top of the mounting plate 520. A turntable 540 is fixed to the end of the output shaft of the dual-axis motor 530. A connecting rod 550 is fixed to one side of the turntable 540. Sliding rods 560 symmetrically slide through the top of the slag removal cylinder 100. A scraping ring 570 is fixed to the bottom end of the sliding rod 560. A moving rod 580 is fixed to the top of the scraping ring 570. A square groove 590 is formed through the middle of one side of the moving rod 580. The sliding rod 560 passes through the top of the mounting plate 520 and the outer wall of the scraping ring 570. The connecting rod 550 is located inside the square groove 590 and its outer side wall is in contact with the inner side wall of the square groove 590. The diameter of the turntable 540 is smaller than the length of the square groove 590. By using the scraping mechanism 500, the turntable 540 is rotated by starting the dual-shaft motor 530, which causes the connecting rod 550 to move in a circular motion. This causes the connecting rod 550 to squeeze the side wall of the square groove 590, which in turn causes the moving rod 580 to move up and down. This causes the sliding rod 560 to move the scraper ring 570 up and down, scraping the side wall of the slag removal cylinder 100. This facilitates the scraping of the pulp, allowing it to fall quickly, improving discharge efficiency and reducing residue.

[0025] In use, this invention works as follows: During slag removal, kraft pulp is poured into the filter cylinder 600. The drive motor 300 is started, causing the mounting cylinder 310 to rotate, which in turn rotates the filter cylinder 600, centrifuging the pulp and leaving the waste residue inside the filter cylinder 600. After slag removal is complete, the pull plate 480 is pulled, causing the connecting plate 460 to move. This causes the connecting plate 460 to move the locking block 470, causing the locking block 470 to retract into the shrinkage cavity 440, thereby releasing the mounting block. Block 410 blocks 470, pulls the filter cylinder 600, and disassembles the filter cylinder 600 as a whole, so that all the filter residue inside the filter cylinder 600 can be removed. Then, the dual-shaft motor 530 is started, which drives the turntable 540 to rotate, causing the connecting rod 550 to move in a circular motion. This causes the connecting rod 550 to squeeze the side wall of the square groove 590, which drives the moving rod 580 to move up and down, causing the slide rod 560 to drive the scraper ring 570 to move up and down, scraping the side wall of the slag removal cylinder 100 to reduce pulp residue.
