Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, specifically a high-consistency pulper for papermaking. Background Technology

[0002] High-consistency pulpers are widely used in the paper industry. They are machines used to break down, dissolve, and disperse wetted waste paper. They can shred waste newspapers or scraps of paper into fibrous pulp.

[0003] According to a high-consistency pulping device disclosed in the above application (Announcement No.: CN205295778U), a multi-layer filtration mechanism is set up to further improve the quality of pulping. The fiber-resolving protrusions are set at the edge of the pulper tank, which can effectively increase the collision rate and friction rate of waste paper in the pulper tank and improve the pulping effect.

[0004] However, in actual use, while the fiber protrusions on the inner wall of the tank can assist in crushing waste paper thrown to the edge of the tank by centrifugal force, their fixed position causes some waste paper to get stuck on their surface or become blocked at that position, affecting subsequent continuous waste paper crushing. Therefore, we propose a high-consistency pulper for papermaking. Utility Model Content

[0005] The purpose of this invention is to provide a high-consistency pulper for papermaking to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-consistency pulper for papermaking, comprising a base, a tank body fixedly installed on the top of the base, a top cover detachably installed on the top of the tank body, a discharge pipe fixedly installed on the bottom of the tank body, a motor fixedly installed on the inner wall of the bottom of the base, a rotating shaft fixedly installed through the inner wall of the bottom of the motor, a spiral belt fixedly installed on the outer wall of the rotating shaft, and a dispersion component for accelerating the crushing of high-consistency waste paper pulp arranged inside the tank body. The dispersion component includes a fixing frame fixedly installed on the inner wall of the top of the tank body, a turntable rotatably installed on the lower surface of the center of the fixing frame, a gear ring fixedly installed on the outer wall of the top of the rotating shaft, a small gear rotatably installed on the lower surface of the center of the fixing frame, a connecting rod fixedly connected to the arc-shaped outer wall of the turntable, a dispersion plate fixedly installed at the end of the connecting rod away from the turntable, and a perforation formed on the inner wall of the dispersion plate.

[0007] Preferably, the bottom of the tank is inclined with a lower center and a higher outer side, and the pivot is located at the center of the bottom of the tank.

[0008] Preferably, the inner surface of the turntable is provided with teeth that mesh with the pinion, and one side of the pinion meshes with the gear ring, while the other side of the pinion meshes with the inner surface of the turntable.

[0009] Preferably, the number of dispersion plates is set in three sets, and the three sets of dispersion plates are arranged in a circumferential array on the lower surface of the fixing frame. The top of the dispersion plates is set in an L-shape, and the bottom inner wall of the fixing frame is provided with an annular groove that matches the top of the dispersion plates.

[0010] Preferably, the perforation is configured in the shape of ">", and the opening of the ">" shaped perforation faces the center of the tank.

[0011] Preferably, a swing crushing assembly is provided on the side of the dispersing plate near the center of the tank. The swing crushing assembly includes a rotating rod rotatably mounted on the inner wall of the dispersing plate. A hinge block is fixedly mounted through the rotating rod. A coil spring is sleeved on the outer wall of the end of the rotating rod. A collision rod is rotatably mounted on the inner wall of the side of the hinge block. A spike is fixedly mounted on the arc-shaped outer wall of the collision rod.

[0012] Preferably, the number of spikes is set to multiple sets, which are evenly distributed on the outer surface of the collision rod, and adjacent sets of spikes are staggered.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the arrangement and cooperation of the fixed frame, turntable, gear ring, pinion, connecting rod, dispersing plate, and perforations, the high-concentration slurry in the tank will rotate with the rotation of the rotating shaft and the spiral belt. Under the transmission of the pinion and gear ring, the turntable drives the dispersing plate to rotate in the opposite direction relative to the rotating shaft below the fixed frame. Larger pieces of pulp move outward along the tangential direction of the slurry rotation and collide head-on with the dispersing plate. At this time, the perforations inside the dispersing plate and the bends and corners inside the perforations will also have an auxiliary crushing effect on the pulp. At the same time, larger pieces of pulp will also come into contact with the collision rod. Due to the rotatability of the collision rod and the hinge block, the arrangement of the spikes improves the ability to cope with the impact of large pieces of pulp. The staggered spikes can effectively achieve the piercing and crushing effect of large pieces of pulp, improve the crushing efficiency of the device for larger pieces of pulp, and thus improve the production and processing efficiency of the device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 The diagram shows a high-consistency pulper for papermaking, including a base 1, a tank 2 fixedly mounted on the top of the base 1, a top cover 3 detachably mounted on the top of the tank 2, a discharge pipe 4 fixedly mounted on the bottom of the tank 2, a motor 5 fixedly mounted on the inner wall of the bottom of the base 1, a rotating shaft 6 fixedly mounted through the output end of the motor 5 through the inner wall of the bottom of the tank 2, a spiral belt 7 fixedly mounted on the outer wall of the rotating shaft 6, and a dispersion component for accelerating the crushing of high-consistency waste paper pulp inside the tank 2. The dispersion component includes a fixed frame 8 fixedly mounted on the inner wall of the top of the tank 2, a turntable 9 rotatably mounted on the lower surface of the center of the fixed frame 8, a gear ring 10 fixedly mounted on the outer wall of the top of the rotating shaft 6, a pinion 11 rotatably mounted on the lower surface of the center of the fixed frame 8, a connecting rod 12 fixedly connected to the arc-shaped outer wall of the turntable 9, a dispersion plate 13 fixedly mounted on the end of the connecting rod 12 away from the turntable 9, and a perforation 14 opened on the inner wall of the dispersion plate 13.

[0023] Please see Figure 1 , Figure 2The top cover 3 is detachable, so that the top of the tank 2 serves as the feeding end during processing, while the discharge pipe 4 is located at the bottom of the tank 2. It can be used as a liquid discharge pipe or a slag discharge pipe in actual use. At the same time, the base 1 has a cavity for the motor 5 to be installed inside, and ventilation windows are provided on both sides of the cavity to facilitate the wiring of the motor 5 and meet the heat dissipation requirements of the motor 5 during operation. Furthermore, the spiral belt 7 is located at the center of the tank 2. When the motor 5 is started, it creates an upward conveying motion of the pulp flowing to the bottom area of ​​the tank 2, so as to continuously push the thick pulp with higher concentration upward and avoid its deposition in the bottom area of ​​the tank 2, which would affect the pulping effect of the device.

[0024] The bottom of the tank body 2 is set in an inclined shape with the center lower and the outer side higher, and the rotating shaft 6 is located at the center of the bottom of the tank body 2.

[0025] Please see Figure 2 Because the bottom of the tank 2 is low, the highly concentrated pulp inside the tank 2 will gather towards the center along the bottom inner wall of the tank 2 under the action of gravity. This, in conjunction with the spiral belt 7 rotating with the shaft 6, will generate an upward movement tendency, thus achieving the effect of breaking up and crushing.

[0026] The inner surface of the turntable 9 is provided with teeth that mesh with the pinion 11, and one side of the pinion 11 meshes with the gear ring 10, while the other side of the pinion 11 meshes with the inner surface of the turntable 9.

[0027] Please see Figure 4 Multiple pinions 11 are arranged in a circular array on the lower surface of the center of the fixed frame 8. At the same time, the top end of the rotating shaft 6 passes through the turntable 9 and is rotatably connected to the lower surface of the center of the fixed frame 8. Through the transmission of the pinions 11, when the rotating shaft 6 drives the gear ring 10 to rotate, the turntable 9 rotates in the opposite direction of the rotation of the rotating shaft 6. Due to the driving of the rotating shaft 6 and the spiral belt 7, the flow direction of the pulp in the tank 2 is always opposite to the rotation direction of the turntable 9, so as to cooperate with the dispersing plate 13 to break up the larger pieces of pulp thrown out along the tangential direction of the pulp flow.

[0028] The number of dispersion plates 13 is set in three sets. The three sets of dispersion plates 13 are arranged in a circular array on the lower surface of the fixing frame 8, and the top of the dispersion plates 13 is set in an L-shape. The bottom inner wall of the fixing frame 8 is provided with an annular groove that matches the top of the dispersion plates 13.

[0029] Please see Figure 2 , Figure 3The arrangement of three sets of dispersing plates 13 ensures the device's efficiency in crushing larger pieces of pulp. At the same time, the L-shaped connecting part at the top of the dispersing plate 13 cooperates with the annular groove inside the fixing frame 8 to provide a certain support force for the dispersing plate 13 in the vertical direction, ensuring that it can always rotate along the inner surface of the tank 2 and avoid bending damage.

[0030] The perforation 14 is set in the shape of ">", and the opening of the perforation 14 in the ">" shape faces the center of the tank body 2.

[0031] Please see Figure 5 The perforations 14 are arranged in multiple sets, and the multiple sets of perforations 14 are evenly distributed in a vertical linear array on the inner wall of the dispersing plate 13. Due to the ">" shape of the perforations 14, when the dispersing plate 13 impacts larger pieces of pulp, the bending corners inside the perforations 14 will also have an auxiliary crushing effect on the pulp, thereby improving the crushing efficiency of the device for larger pieces of pulp and thus improving the production and processing efficiency of the device.

[0032] A swing crushing assembly is provided on the side of the dispersing plate 13 near the center of the tank body 2. The swing crushing assembly includes a rotating rod 15 rotatably installed on the inner wall of the dispersing plate 13. A hinge block 16 is fixedly installed through the rotating rod 15. A coil spring 17 is sleeved on the outer wall of the end of the rotating rod 15. A collision rod 18 is rotatably installed on the inner wall of the side of the hinge block 16. A spike rod 19 is fixedly installed on the arc-shaped outer wall of the collision rod 18.

[0033] Please see Figure 5 , Figure 6 The number of oscillating crushing components corresponds one-to-one with the perforations 14, and the oscillating crushing components are set on the side of the perforations 14 near the center of the tank 2, so as to better achieve the crushing effect of the pulp in the tank 2 in conjunction with the perforations 14. Specifically, the inner wall of the dispersion plate 13 near the center of the tank 2 is provided with an oscillating groove whose height is adapted to the height of the hinge block 16. The two ends of the rotating rod 15 are rotatably connected to the upper and lower inner walls of the oscillating groove, and the two ends of the coil spring 17 are fixedly connected to the arc-shaped outer wall of the rotating rod 15 and the inner wall of the oscillating groove, so that the rotating rod 15 always has the tendency to rotate in the opposite direction to achieve reset when it drives the hinge block 16 to rotate.

[0034] The number of spikes 19 is set in multiple groups, and the multiple groups of spikes 19 are evenly distributed on the outer surface of the collision rod 18, and the adjacent groups of spikes 19 are staggered.

[0035] Please see Figure 6A reinforcing ring is provided at the connection between the collision rod 18 and the hinge block 16 to ensure the rotatability of the collision rod 18 on the side of the hinge block 16 and its stability during use. At the same time, the staggered arrangement of the spikes 19 enables it to better cope with the impact of large pieces of pulp. Furthermore, under the horizontal swing of the rotating rod 15 and the rotation of the collision rod 18 itself, the staggered spikes 19 can effectively achieve the piercing and crushing effect of large pieces of pulp, thereby improving the efficiency of the device in crushing and processing pulp.

[0036] Working principle: Open the top cover 3 and pour water and the high-concentration pulp to be crushed into the internal cavity of the tank 2 in proportion. Then close the top cover 3 and start the motor 5 to drive the rotating shaft 6 to rotate. At this time, under the transmission of the pinion 11 and the gear ring 10, the turntable 9 drives the dispersing plate 13 to rotate in the opposite direction relative to the rotating shaft 6 below the fixed frame 8. Through the action of the rotating shaft 6 and the spiral belt 7, the high-concentration pulp in the bottom area of ​​the tank 2 moves upward and spreads to the surroundings. When the pulp rotates, the larger diameter pulp blocks move outward along the tangent of the pulp rotation and collide head-on with the dispersing plate 13. At this time, the bending corners inside the dispersing plate 13 also have an auxiliary crushing effect on the pulp, improving the crushing efficiency of the device for larger pulp blocks, thereby improving the production and processing efficiency of the device.

[0037] After crushing for a certain period of time, the discharge pipe 4 is opened to discharge the slurry in the tank 2, so as to obtain the crushed slurry, which facilitates the subsequent paper production work.
