Description

Technical Field

[0001] This application relates to the field of pulping equipment technology, and in particular to a device for improving the bulking of pulping equipment. Background Technology

[0002] As a key piece of equipment, pulpers are widely used in waste paper pulping production lines. Their main function is to efficiently disintegrate waste paper. With the rapid development and technological progress of the paper industry, how to improve waste paper disintegration efficiency and reduce equipment maintenance costs has become a key focus of the industry.

[0003] In existing waste paper pulping production lines, chain conveyor belts are typically used to transport waste paper bales into the pulper. However, in practice, due to the large size and solidity of the waste paper bales, a significant impact is generated when they fall directly from the chain conveyor belt into the pulper. Common industry solutions to this problem include: adjusting the height of the chain conveyor belt to reduce the free fall distance of the waste paper bales; adding simple cushioning pads or rubber baffles to absorb some of the impact energy; and improving the stacking method of the waste paper bales to allow them to loosen naturally during transport. While these methods can alleviate the impact problem to some extent, they still have significant limitations.

[0004] Regarding the aforementioned technologies, existing technologies cannot effectively solve the problem of strong impact caused by large-sized waste paper bales on the pulper rotor. At the same time, they fail to adequately improve the difficulties in disintegration caused by the integrity and density of the waste paper bales, resulting in unstable pulper operation, increased maintenance frequency, and ultimately affecting the working efficiency and economic benefits of the entire pulping line. Utility Model Content

[0005] To overcome the above problems, this application provides a device for improving the bulking of pulpers.

[0006] The technical solution provided in this application for improving the bagging device of a pulper is as follows:

[0007] A device for improving the bulking of a pulper includes a connecting assembly comprising a steel plate arranged parallel to the rotation axis of the pulper rotor. One side of the steel plate passes through the side wall of the pulper, with one side located inside the pulper and the other end located outside the pulper. The steel plate is connected to the pulper and is located below the chain conveyor.

[0008] By adopting the above technical solution, the steel plate, as the core component of the connecting assembly, is set parallel to the rotation axis of the pulper rotor. It can effectively receive the waste paper bales falling from the chain conveyor. One side of the steel plate passes through the side wall of the pulper and is fixedly connected to ensure structural stability. At the same time, the design located below the chain conveyor allows the waste paper bales to be blocked by the steel plate during the falling process, playing a preliminary buffering role and effectively solving the problem of strong impact caused by large-sized waste paper bales on the pulper rotor. In addition, the setting of the steel plate can also perform preliminary loosening of the waste paper bales, improve the integrity and density of the waste paper bales, and lay the foundation for more efficient subsequent pulping operations.

[0009] In one specific implementation, the system further includes two rotating assemblies, both located inside the pulper and on either side of the steel plate. The distribution direction of the two rotating assemblies is perpendicular to the rotation axis of the pulper rotor. Each rotating assembly includes a rotating element and an inclined plate. The rotating element includes a rotating rod and a torsion spring. The rotating rod is perpendicular to the rotation axis of the pulper rotor, with one end close to the side wall of the pulper and the other end facing the rotation axis of the pulper rotor. Each end of the rotating rod is connected to a rotating seat, which is connected to the steel plate. The torsion spring is sleeved on the rotating rod. The inclined plate is rotatably connected to the rotating rod, with one end of the torsion spring connected to the rotating rod and the other end connected to the inclined plate. The inclined plate rotates along the axial direction of the rotating rod towards or away from the bottom of the pulper.

[0010] By adopting the above technical solution, the rotating component can effectively buffer the impact force when the paper bales fall. Specifically, the inclined plate rotates around the rotating rod under the action of the paper bales' gravity, causing the paper bales to gradually slide towards the bottom of the pulper, thereby avoiding the strong impact caused by the direct fall of the paper bales. At the same time, the elastic characteristics of the torsion spring further absorb the energy generated during the fall of the paper bales, reducing damage to the equipment and improving the stability and service life of the device. In addition, this design also promotes the initial dispersion of the paper bales, providing favorable conditions for the subsequent pulping process.

[0011] In one specific implementation, the system further includes a bale assembly, which includes a sliding member comprising a connecting plate, a first buffer plate, and a second buffer plate. The connecting plate is connected to the side of the inclined plate away from the steel plate and is located on the side of the inclined plate near the bottom of the pulper. The first buffer plate and the second buffer plate are both located on the side of the inclined plate near the bottom of the pulper. When the bale presses the inclined plate to rotate, the inclined plate, the first buffer plate, and the second buffer plate form a three-tiered step with a height difference.

[0012] By adopting the above technical solution, the paper bales slide sequentially onto the inclined plate, the first buffer plate, and the second buffer plate, achieving multi-level buffering of the paper bales and effectively reducing the impact force generated during the descent. Simultaneously, the intermittent levitation and re-falling of the paper bales during the sliding process on the three steps helps disperse them, thereby improving the pulper's efficiency in disintegrating waste paper bales and reducing the risk of impact damage during equipment operation.

[0013] In one specific implementation, the bulk packaging assembly further includes a bulk packaging component, which includes a plurality of saw teeth. The plurality of saw teeth are evenly connected to the inclined plate, the first buffer plate, and the second buffer plate. The saw teeth connected to the inclined plate are located on the side of the inclined plate away from the bottom of the pulper. The saw teeth connected to the first buffer plate are located on the side of the first buffer plate away from the bottom of the pulper. The saw teeth connected to the second buffer plate are located on the side of the second buffer plate away from the bottom of the pulper. When the inclined plate is rotated to a suitable angle, the teeth of the saw teeth face the side of the steel plate.

[0014] By adopting the above technical solution, when the paper bale slides down the inclined plate, the first buffer plate, and the second buffer plate, the saw teeth can generate shearing force on the paper bale, thereby effectively tearing the overall structure of the paper bale and dispersing it into smaller pieces more quickly, improving the pulper's processing efficiency for waste paper. Furthermore, the saw tooth design can increase the frictional resistance during the paper bale's descent, further reducing the bale's falling speed, decreasing the impact force on the pulper rotor, improving equipment operational stability, and reducing maintenance costs.

[0015] In one specific implementation, the bulk assembly further includes a blocking element comprising a plurality of blocking rods. The plurality of blocking rods are evenly connected to the inclined plate, the first buffer plate, and the second buffer plate. The blocking rods connected to the inclined plate are located on the side of the inclined plate away from the bottom of the pulper. The blocking rods connected to the first buffer plate are located on the side of the first buffer plate away from the bottom of the pulper. The blocking rods connected to the second buffer plate are located on the side of the second buffer plate away from the bottom of the pulper. When the inclined plate rotates to a suitable angle, the blocking rods are arranged parallel to the rotation axis of the pulper rotor.

[0016] By adopting the above technical solution, the paper bales collide with the barrier bars during their descent, effectively cushioning the bales. Simultaneously, the barrier bars cause the bales to gradually loosen during impact, improving their integrity and density, reducing impact on the pulper rotor, and enhancing the pulper's efficiency and stability. Furthermore, the barrier bars are evenly distributed on the inclined plates, the first buffer plate, and the second buffer plate, ensuring that the bales are repeatedly blocked and dispersed as they slide down multiple steps, further improving the bale-loosening effect.

[0017] In one specific implementation, the blocking member further includes a baffle plate connected to the inclined plate on the side near the rotation axis of the pulper rotor. The baffle plate is perpendicular to the inclined plate, and the side of the inclined plate near the rotation axis of the pulper rotor, the side of the first buffer plate near the rotation axis of the pulper rotor, and the side of the second buffer plate near the rotation axis of the pulper rotor are all connected to the baffle plate.

[0018] By adopting the above technical solution, the baffle can effectively prevent the paper bale from deviating from the predetermined path during the sliding process, ensuring that the paper bale passes through the inclined plate, the first buffer plate and the second buffer plate in sequence, achieving a stable buffering and bale dispersal effect. At the same time, by limiting the inclined plate, the first buffer plate and the second buffer plate on the side close to the rotation axis of the pulper rotor, the paper bale is prevented from directly impacting the pulper rotor, thereby reducing the risk of equipment damage and improving the reliability of pulper operation.

[0019] In one specific implementation, the connecting assembly further includes an embedded part, which includes an embedded plate and a plurality of anchor bars. The embedded plate is located outside the pulper and is perpendicular to the rotation axis of the pulper rotor. The embedded plate is connected to the bottom of the steel plate, and the plurality of anchor bars are all connected to the side of the embedded plate away from the steel plate. The embedded plate and the plurality of anchor bars are embedded in the floor slab.

[0020] By adopting the above technical solution, the fixing effect between the connecting components and the floor slab can be enhanced, the stability of the overall device can be improved, and multiple anchor bars are evenly distributed and connected to the pre-embedded plate, and are buried together in the floor slab, which effectively prevents the device from being displaced or loosened due to the impact of waste paper bags during operation, and ensures the long-term reliable operation of the device.

[0021] In one specific implementation, the connecting assembly further includes a reinforcing member comprising a first reinforcing rib and at least one second reinforcing rib. The first reinforcing rib is located outside the pulper and is connected to the steel plate. The first reinforcing rib is arranged along the rotation axis of the pulper rotor. The second reinforcing rib is located inside the pulper and is arranged along a rotation axis perpendicular to the pulper rotor. The second reinforcing rib is connected to the steel plate. One end of the second reinforcing rib is connected to the side wall of the pulper, and the other end faces the rotation axis of the pulper rotor.

[0022] By adopting the above technical solution, the setting of the first reinforcing rib and the second reinforcing rib can significantly enhance the overall structural strength of the device. The first reinforcing rib is located on the outside of the pulper and is set along the rotation axis, which effectively prevents the steel plate from deforming when it is subjected to external impact. The second reinforcing rib is located inside the pulper and is set perpendicular to the rotation axis, which further strengthens the connection stability between the steel plate and the side wall of the pulper, ensuring that the device maintains reliable performance during long-term operation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The designed bale-breaking device for the pulper, located below the chain conveyor, allows the waste paper bales to be blocked by steel plates during their descent, providing initial cushioning and effectively solving the problem of strong impact caused by large-sized waste paper bales on the pulper rotor. In addition, the steel plates can also perform initial bale-breaking treatment, improving the integrity and density of the waste paper bales and laying the foundation for more efficient subsequent shredding operations.

[0025] 2. The designed bale-dispersing device for the pulper features an inclined plate that rotates around a rotating rod under the weight of the bales, causing them to gradually slide towards the bottom of the pulper, thus avoiding the strong impact of direct falls. Simultaneously, the elastic properties of the torsion spring further absorb the energy generated during the bale's descent, reducing damage to the equipment and improving the device's stability and lifespan. Furthermore, this design promotes initial bale dispersion, providing favorable conditions for subsequent pulping.

[0026] 3. The designed bale-dispersing device for the pulper has evenly distributed blocking rods on the inclined plate, the first buffer plate, and the second buffer plate, ensuring that the paper bales are blocked and dispersed multiple times when sliding down the multi-step steps, further improving the bale-dispersing effect.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0033] This application discloses an embodiment of a device for improving the bulking of pulpers.

[0034] Example 1

[0035] Reference Figure 1 A device for improving the bagging of a pulper includes a connecting assembly 1, two rotating assemblies 2 and two bagging assemblies 3, wherein the rotating assemblies 2 are mounted on the connecting assembly 1 and the bagging assemblies 3 are mounted on the rotating assemblies 2.

[0036] Reference Figure 1 The connecting assembly 1 includes a steel plate 11, a reinforcing member 12, and an embedded member 13. In this embodiment, the steel plate 11 is a rectangular plate, and the steel plate 11 is arranged parallel to the rotation axis of the rotor of the pulper 4. One side of the steel plate 11 passes through the side wall of the pulper 4, with one end located inside the pulper 4 and the other end located outside the pulper 4. The steel plate 11 is fixedly connected to the side wall of the pulper 4 by screws, and the connection between the steel plate 11 and the pulper 4 is sealed by a sealing gasket to reduce the leakage of pulp from the pulper 4 from the connection between the steel plate 11 and the pulper 4. At the joint, the steel plate 11 is located below the waste paper chain conveyor. The steel plate 11 is located inside the pulper 4 and is inclined on the side near the bottom of the pulper 4. The inclined surface of the steel plate 11 is inclined from the side wall of the pulper 4 to the rotation axis of the rotor of the pulper 4 towards the side away from the bottom of the pulper 4. The waste paper bales are conveyed to the outlet of the chain conveyor through the waste paper chain conveyor. When entering the pulper 4, due to the height difference, they fall onto the steel plate 11 due to gravity. The steel plate 11 blocks the falling paper bales, plays a buffering role, and also helps to disperse the paper bales.

[0037] Reference Figure 1The reinforcing member 12 includes a first reinforcing rib 121 and at least one second reinforcing rib 122. The first reinforcing rib 121 is located outside the pulper 4 and close to the steel plate 11. The first reinforcing rib 121 is arranged along the rotation axis of the pulper 4 rotor and is welded to the steel plate 11. In this embodiment, there are two second reinforcing ribs 122, both located inside the pulper 4 and distributed along the rotation axis of the pulper 4 rotor. The second reinforcing ribs 122 are arranged perpendicular to the rotation axis of the pulper 4 rotor and are welded to the steel plate 11. One end of the second reinforcing rib 122 is welded to the pulper 4 rotor. The side wall of the pulper 4, with the other end facing the rotation axis of the pulper 4 rotor, can further enhance the overall strength of the device; the embedded part 13 includes an embedded plate 131 and multiple anchor bars 132. The embedded plate 131 is located outside the pulper 4 and is perpendicular to the rotation axis of the pulper 4 rotor. The embedded plate 131 is welded to the bottom of the steel plate 11. The first reinforcing rib 121 is welded to the embedded plate 131. Multiple anchor bars 132 are all welded to the side of the embedded plate 131 away from the steel plate 11. The anchor bars 132 are set perpendicular to the embedded plate 131 and are set parallel to each other. The embedded plate 131 and multiple anchor bars 132 are embedded in the floor slab, which can further strengthen the device and ensure the stability of the device.

[0038] Reference Figure 1 , Figure 2 and Figure 3 Both rotating components 2 are located inside the pulper 4, on both sides of the steel plate 11. The distribution direction of the two rotating components 2 is perpendicular to the rotation axis of the pulper 4 rotor. Each rotating component 2 includes a rotating element 21 and an inclined plate 22. The rotating element 21 includes a rotating rod 211 and a torsion spring 212. The rotating rod 211 is perpendicular to the rotation axis of the pulper 4 rotor. One end of the rotating rod 211 is close to the side wall of the pulper 4, and the other end faces the rotation axis of the pulper 4 rotor. Each end of the rotating rod 211 has a... A rotating seat 2111 is welded to the steel plate 11. A torsion spring 212 is sleeved on the rotating rod 211. An inclined plate 22 is rotatably connected to the rotating rod 211 and rotates synchronously with the rotating rod 211. One end of the torsion spring 212 is welded to the rotating rod 211, and the other end is welded to the inclined plate 22. When the paper bale falls onto the steel plate 11, the paper bale slides onto the inclined plate 22. Due to the weight of the paper bale itself, the paper bale presses the inclined plate 22 to rotate toward the bottom of the pulper 4, which can further buffer the paper bale.

[0039] Reference Figure 1 , Figure 2 and Figure 3The loose bale assembly 3 corresponds one-to-one with the rotating assembly 2. The loose bale assembly 3 includes a sliding component 31 and a loose bale component 32. The sliding component 31 includes a connecting plate 311, a first buffer plate 312, and a second buffer plate 313. The connecting plate 311 is located on the side of the inclined plate 22 away from the steel plate 11, and the connecting plate 311 is located on the side of the inclined plate 22 near the bottom of the pulper 4. One side of the connecting plate 311 is welded to the inclined plate 22. The first buffer plate 312 and the second buffer plate 313 are both located on the side of the inclined plate 22 near the bottom of the pulper 4. When the paper bale presses against the inclined plate... When 22 rotates, the inclined plate 22, the first buffer plate 312 and the second buffer plate 313 form three steps. The paper package slides down to the inclined plate 22, the first buffer plate 312 and the second buffer plate 313 in sequence, further cushioning the paper package. At the same time, the paper package is intermittently suspended in the air and falls to the next step as it slides down the three steps with a height difference, which facilitates the dispersion of the paper package. The side of the first buffer plate 312 near the connecting plate 311 and the side of the second buffer plate 313 near the connecting plate 311 are both welded to the connecting plate 311.

[0040] Reference Figure 1 and Figure 2 The loose package component 32 includes multiple saw teeth 321, which are evenly distributed on the inclined plate 22, the first buffer plate 312, and the second buffer plate 313. The saw teeth 321 are welded to the corresponding inclined plate 22, the first buffer plate 312, and the second buffer plate 313. The saw teeth 321 connected to the inclined plate 22 are located on the side of the inclined plate 22 away from the bottom of the pulper 4. The saw teeth 321 connected to the first buffer plate 312 are located on the side of the first buffer plate 312 away from the bottom of the pulper 4. The saw teeth 321 connected to the second buffer plate 313 are located on the side of the second buffer plate 313 away from the bottom of the pulper 4. When the inclined plate 22 rotates to a suitable angle, the teeth of the saw teeth 321 face the side of the steel plate 11. When the paper package rolls along the inclined plate 22, the first buffer plate 312, and the second buffer plate 313, the saw teeth 321 can generate shearing force on the paper package, which facilitates the dispersion of the paper package.

[0041] The implementation principle of Example 1 is as follows: When it is necessary to drop the paper bale into the pulper 4, the waste paper bale is conveyed to the outlet of the waste paper chain conveyor. Then, the paper bale falls onto the steel plate 11 through the outlet of the chain conveyor and slides onto the inclined plate 22. Due to the weight of the paper bale, the paper bale presses the inclined plate 22 to rotate around the rotating rod 211 towards the bottom of the pulper 4. At this time, the paper bale slides onto the inclined plate 22, the first buffer plate 312 and the second buffer plate 313 in sequence, causing the paper bale to be intermittently suspended in the air and then fall to the next step. During the process of the paper bale sliding down, the saw teeth 321 generate a shearing force on the paper bale. After that, the paper bale slides into the pulper 4 and is stirred and dispersed by the rotor of the pulper 4.

[0042] Example 2

[0043] Reference Figure 4The difference between this embodiment and Embodiment 1 is that the bulk packaging assembly 3 further includes a blocking component 33, which includes multiple blocking rods 331 and baffles 332. The multiple blocking rods 331 are evenly distributed on the inclined plate 22, the first buffer plate 312, and the second buffer plate 313. The blocking rods 331 are welded to the corresponding inclined plate 22, the first buffer plate 312, and the second buffer plate 313. The blocking rods 331 connected to the inclined plate 22 are located on the side of the inclined plate 22 away from the bottom of the pulper 4. The blocking rods 331 connected to the first buffer plate 312 are located on the side of the first buffer plate 312 away from the bottom of the pulper 4. The blocking rods 331 connected to the second buffer plate 313 are located on the side of the second buffer plate 313 away from the bottom of the pulper 4. When the inclined plate 22 rotates to a suitable angle... When the paper bale slides down the inclined plate 22, the blocking rod 331 is set parallel to the rotation axis of the pulper 4 rotor. The blocking rod 331 can block the paper bale to further achieve buffering. The paper bale is loosened by collision until it slides down the inclined plate 22, the first buffer plate 312 and the second buffer plate 313 in sequence, and then falls into the pulper 4. The baffle 332 is located on the side of the inclined plate 22 near the rotation axis of the pulper 4 rotor. The baffle 332 is set perpendicular to the inclined plate 22. The side of the inclined plate 22 near the rotation axis of the pulper 4 rotor, the side of the first buffer plate 312 near the rotation axis of the pulper 4 rotor and the side of the second buffer plate 313 near the rotation axis of the pulper 4 rotor are all welded to the baffle 332 to ensure the stability of the device and achieve buffering of the paper bale.

[0044] The implementation principle of Example 2 is as follows: the paper package slides down to the inclined plate 22, the first buffer plate 312 and the second buffer plate 313 in sequence, causing the paper package to be intermittently suspended in the air and then fall to the next step. During the process of the paper package sliding down, the barrier rod 331 collides with the paper package to disperse the paper package. After that, the paper package slides down to the pulper 4 and is dispersed by the rotor of the pulper 4.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
