Description

Technical Field

[0001] This invention belongs to the field of papermaking machinery technology, and more specifically, relates to a paper pulper with automatic feeding function and its feeding method. Background Technology

[0002] Pulp is a fibrous substance made from plant fibers through different processing methods. It can be classified into mechanical pulp, chemical pulp, and chemimechanical pulp according to the processing method, and into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, rag pulp, etc. according to the fiber raw materials used. Pulp is a semi-solid substance and is formed by mixing the raw materials with the solution required for pulping.

[0003] A pulper is a machine used in the wet nonwoven and papermaking industries for breaking down, dissolving, and dispersing pulp, such as pulp boards, waste paper, and scrap paper, into fibrous pulp.

[0004] The operation of a pulper involves the operator pouring raw materials into the pulper chamber through the feed inlet, injecting the solution required for pulping into the chamber, and then crushing the raw materials in the solution using an impeller. The crushed raw materials and solution are then mixed to form pulp. Currently, raw materials are manually poured into the pulper chamber. When the impeller inside the pulper chamber is working, the raw materials enter the pulper through the feed inlet. The impeller rotates at high speed to crush the raw materials. During the high-speed rotation of the impeller, the raw materials come into contact with the impeller, and the force of the impeller's rotation makes the raw materials prone to splashing. The splashed raw materials can easily cut the operator through the pulper's feed inlet, and manual feeding has a high risk factor, making it difficult to guarantee the personal safety of the operators.

[0005] To address the above issues, a search revealed Chinese Patent Publication No. CN 114318921 A, published on April 12, 2022, which discloses a continuous intelligent unloading and crushing production line and method. The production line includes a hoisting device, an automatic unloading device, a pulper, and a control system. The automatic unloading device includes a vertical lifting device, a support frame, a cylinder, a telescopic arm, and a pull plate. The hoisting device hoists the pulp plates onto the vertical lifting device, which is located on one side of the pulper. The pulper is located below the support frame. The cylinder is located above the pull arm, with one end hinged to the support frame and the other end extending to control the raising or lowering of the pull arm. One end of the telescopic arm is hinged to the support frame, and the other end is fitted with a pull plate. Under the control of the telescopic arm, the pull plate pulls the pulp plates layer by layer into the pulper. The pulper is connected to a water inlet pipe, and the vertical lifting device is equipped with a pulp plate weighing sensor. The control system controls the water inlet flow rate and also controls the cylinder, telescopic arm, and hoisting device. Automatic unloading can be achieved by installing a cylinder and a pull arm on the support frame. Combined with the hoisting device, automatic unloading is realized. The pull arm of this invention pulls the pulp board into the pulper layer by layer during the material pulling process. Although it avoids the safety risks of manual operation, it is still difficult to avoid the material splashing generated when the pulp board is pulled into the pulper for crushing. Summary of the Invention

[0006] 1. The problem to be solved

[0007] To address the problem in existing pulpers where raw materials are easily splashed outwards due to the force of impeller rotation during feeding, this invention provides a paper pulper with automatic feeding function and its feeding method. This invention uses a feeding screw in the feeding bin to spirally feed material into the crushing bin, achieving buffered and indirect feeding within the crushing bin, thus avoiding outward splashing caused by direct feeding.

[0008] 2. Technical Solution

[0009] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0010] A paper pulper with automatic feeding function includes a pulp bin, a feeding mechanism, and a crushing mechanism fixedly connected to and communicating with the upper part of the pulp bin. The crushing mechanism includes a vertical crushing bin. The feeding mechanism includes a feeding bin that is horizontally connected to the crushing bin and a feeding screw that is horizontally fixed inside the feeding bin and feeds material into the crushing bin. The feeding screw is externally connected to the output end of a second motor. A feed pipe is externally connected to the upper part of the feeding bin. In actual use, the operator pours raw materials such as pulp board, waste paper, and scrap paper into the feeding bin through the feed pipe. The operator then turns on the second motor, and the output end of the second motor drives the feeding screw to rotate. The rotation of the screw pushes the raw materials inside the feeding bin towards the discharge end of the feeding bin, propelling the raw materials into the crushing bin connected to the feeding bin for crushing. This allows the paper pulper to automatically feed material. Because it is a buffered and indirect feeding method, the raw materials cannot splash out of the feed pipe.

[0011] A further technical solution includes a crushing mechanism comprising a crushing chamber connected to the upper part of a pulping chamber, a screen plate fixed at the connection between the crushing chamber and the pulping chamber, and blades above the screen plate. The blades are sleeved and fixed on a vertical rotating shaft. The fixed end of the rotating shaft is fixedly connected to the output end of a third motor. The far end of the rotating shaft passes through the blades and is generally rotatably connected to the screen plate via a bearing. The third motor is fixed to the upper part of the crushing chamber. The vertical rotating shaft drives the blades to crush the raw material. The crushed material, under its own weight, passes directly through the screen plate and falls into the pulping chamber.

[0012] A further technical solution is that the bottom of the feeding bin where the screen plate is located creates a discharge drop while also providing crushing space for the blades, facilitating the discharge and crushing of raw materials; a discharge gap is reserved between the blades and the screen plate, so that the raw materials can be squeezed out of the screen plate holes by the rotating blades after crushing.

[0013] A further technical solution involves an external injection pipe connecting the pulping chamber to inject water into the chamber, a horizontally rotating spiral stirring rod connected inside the pulping chamber, and a discharge pipe connected to the bottom of the pulping chamber. The upper part receives the material, the middle part mixes the material, and the lower part discharges the material, resulting in uniform mixing and smooth discharge.

[0014] A further advanced technical solution involves a cleaning ring that slides close to the inner wall of the pulping chamber, which can scrape off the residue adhering to the inner wall of the pulping chamber, making cleaning easier.

[0015] A further technical solution involves a spiral stirring rod passing through the center of the cleaning ring to avoid mutual interference. A threaded rod is also laterally rotatably connected inside the pulping chamber. One end of the threaded rod is rotatably connected to an inner wall of the pulping chamber, and the other end passes through the cleaning ring and the other side wall of the pulping chamber before being fixedly connected to the first gear. The connection between the cleaning ring and the threaded rod is threaded. By rotating the first gear, the cleaning ring moves laterally within the pulping chamber, scraping off the residue adhering to the inner wall of the pulping chamber. No opening of the chamber for cleaning is required, making operation convenient and labor-saving.

[0016] In a further technical solution, a sliding rod is also fixedly connected laterally inside the pulping chamber, with both ends of the sliding rod fixed to the left and right inner side walls of the pulping chamber, respectively; the cleaning ring is slidably connected to the sliding rod, which can guide the lateral back-and-forth movement of the cleaning ring.

[0017] A further technical solution involves meshing the first gear with the second gear, with the second gear rotatably connected to the outer wall of the pulping chamber. The diameter of the first gear is smaller than that of the second gear. Rotating the second gear drives the first gear to rotate, making the operation more dynamic. A second handle can be fixedly installed at the eccentric position of the second gear surface, making the cleaning work more labor-saving and convenient.

[0018] A further technical solution involves a brush fixedly connected to the center of the cleaning ring. As the cleaning ring slides back and forth laterally, it cleans the blades of the spiral stirring rod.

[0019] A feeding method for a paper pulper with automatic feeding function is provided, in which the raw material is conveyed to the crushing chamber by a feeding screw in the feeding bin, so as to achieve buffered and indirect feeding.

[0020] 3. Beneficial effects

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] (1) In the paper pulping machine of the present invention, when feeding, the operator pours the raw material into the inside of the feeding bin through the feeding pipe. The operator turns on the second motor, and the output end of the second motor drives the screw rod to rotate. The rotation of the screw rod pushes the raw material to move inside the feeding bin and into the crushing bin for the next process. This allows the paper pulping machine to automatically feed the raw material and prevents the raw material from splashing inside the paper pulping machine, making it easier for the raw material to enter the next process inside the paper pulping machine. It can automatically and stably supply the raw material, reduce the cost of manual supervision, and has a simple structure. Its cost is low and it is easy to maintain. By setting up the feeding bin, the second motor and the screw rod, it is easy to push the raw material. During the operation of the paper pulping machine, there is no need for manual pushing of the raw material to feed it, which improves the safety of the manual operation process.

[0023] (2) In the paper pulping machine of the present invention, the rotating screw pushes the raw material into the interior of the crushing chamber. The operator turns on the third motor. The output end of the third motor drives the rotating shaft and blades to crush the raw material. The screen plate screens the crushed material. The material falls into the interior of the pulping chamber through the screen plate and enters the next process to fully crush the solid raw material. The crushed material is easier to pulp in the interior of the pulping chamber. The solution is injected into the interior of the pulping chamber through the injection pipe. After the raw material is crushed into material, it is mixed with the solution, which effectively improves the pulping efficiency of the paper pulping machine. At the same time, it improves the working efficiency of the paper pulping machine. It is convenient for the fiber in the material to be evenly mixed with the solution, so that the pulp content and color in the solution are more uniform. It is convenient for the paper pulping machine to mix the material and the solution into pulp. By setting the third connecting chamber, the third motor, the rotating shaft, the screen plate and the blades, the uniformity of pulp mixing in the paper pulping machine is effectively improved.

[0024] (3) When the operator needs to inspect the inside of the pulping chamber of the paper pulping machine of the present invention, the operator will separate the nut and bolt by screwing them apart. The operator will remove the sealing chamber door from the inside of the pulping chamber through the first handle. The operator can then inspect the inside of the pulping chamber. The sealing chamber door, bolt, nut, first handle and limit groove are provided so that the sealing chamber door can be opened, which is convenient for the operator to inspect the inside of the pulping chamber. By regularly inspecting the inside of the pulping chamber, the stability of the paper pulping machine is effectively guaranteed. By regularly inspecting the paper pulping machine, the efficiency of the paper pulping machine in the pulping process is guaranteed.

[0025] (4) In the paper pulper of the present invention, when it is necessary to clean the inner wall of the pulp bin in the paper pulper, the operator reverses the second handle. The reverse rotation of the second handle drives the connecting shaft and the second gear to reverse, and the reverse rotation of the second gear drives the first gear meshing with the second gear to rotate forward. The forward rotation of the first gear drives the threaded rod to rotate forward, and the forward rotation of the threaded rod drives the cleaning ring to move on the outer wall of the threaded rod. The cleaning ring scrapes against the inner wall of the pulp bin, and the cleaning ring scrapes against the waste pulp adhering to the inner wall of the pulp bin. The pulp is pushed towards the sealed chamber door. The operator separates the nut and bolt by screwing them together. The operator then removes the sealed chamber door from the inside of the pulping chamber using the first handle. The operator cleans the waste pulp scraped by the cleaning ring and the waste pulp on the inner wall of the cleaning ring, making it easier to clean the waste pulp uniformly and reducing the difficulty of cleaning the waste pulp. The sealed chamber door and cleaning ring facilitate the rapid cleaning of the pulp on the inner wall of the pulping chamber, effectively improving the cleaning efficiency of the pulping chamber and making it easier for the paper pulper to process the next batch of raw materials.

[0040] The present invention will be further described below with reference to specific embodiments.

[0041] Example 1

[0042] This embodiment features a paper pulper with automatic feeding function, such as... Figure 1 , 2As shown in Figures 3, 4, and 8, the device includes a pulping bin 1, a feeding mechanism, and a crushing mechanism 6 fixedly connected to and communicating with the pulping bin 1. The crushing mechanism 6 includes a vertical crushing bin 61. The feeding mechanism includes a feeding bin 52 that is laterally connected to the crushing bin 61, and a feeding screw 54 that is laterally fixed inside the feeding bin 52 and feeds material to the crushing bin 61. The feeding screw 54 is externally connected to the output end of a second motor 51. A feed pipe 53 is externally connected to the upper part of the feeding bin 52.

[0043] In this embodiment, the paper pulper with automatic feeding function and its feeding method are used in the following way: the operator pours raw materials such as pulp board, waste paper and scrap paper into the feeding bin 52 through the feed pipe 53. The operator turns on the second motor 51, and the output end of the second motor 51 drives the feeding screw 54 to rotate. The rotation of the screw pushes the raw materials inside the feeding bin 52 toward the discharge end of the feeding bin 52. The raw materials are pushed into the crushing bin 61 connected to the feeding bin 52 for crushing, so that the paper pulper can automatically feed. Because it is a buffer and the feeding is indirect into the crushing bin 61, the raw materials cannot splash out of the feed pipe 53.

[0044] Example 2

[0045] The paper pulper with automatic feeding function in this embodiment has the same basic structure as in embodiment 1, with the following differences or improvements: Figure 1 , 2 As shown in Figures 3 and 6, the crushing mechanism 6 includes a crushing chamber 61 connected to the upper part of the pulping chamber 1, a screen plate 64 fixed at the connection between the crushing chamber 61 and the pulping chamber 1, and blades 65 above the screen plate 64. The blades 65 are sleeved and fixed on a vertical rotating shaft 63. The fixed end of the rotating shaft 63 is fixedly connected to the output end of a third motor 62. The distal end of the rotating shaft 63 passes through the blades 65 and is generally rotatably connected to the screen plate 64 via a bearing. The third motor 62 is fixed to the upper part of the crushing chamber 61. The vertical rotating shaft 63 drives the blades 65 to crush the raw material. The crushed material, under its own weight, passes directly through the screen plate 64 and falls into the pulping chamber 1. The horizontal plane of the screen plate 64 is lower than the horizontal plane of the bottom of the feeding hopper 52, forming a discharge drop and providing crushing space for the blades 65, facilitating the discharge and crushing of the raw material. A discharge gap is reserved between the blades 65 and the screen plate 64 to facilitate the crushing of the raw material by squeezing it out of the holes of the screen plate 64 through the rotating blades. The pulping bin 1 is connected to an external injection pipe 13 to inject water into the bin. The pulping bin 1 is connected to a horizontally rotating spiral stirring rod 22. The bottom of the pulping bin 1 is connected to an external discharge pipe 12, which receives material at the top, mixes material in the middle, and discharges material at the bottom, ensuring uniform mixing and smooth discharge.

[0046] Example 3

[0047] The paper pulper with automatic feeding function in this embodiment has the same basic structure as in embodiment 2, but the differences or improvements are as follows: Figure 2 , 4 As shown in Figure 5, a cleaning ring 41 is slidably connected to the inner wall of the pulping chamber 1, which can scrape off the residue adhering to the inner wall of the pulping chamber 1, making cleaning convenient. The spiral stirring rod 22 passes through the center of the cleaning ring 41 to avoid mutual interference. A threaded rod 4 is also rotatably connected to the pulping chamber 1. One end of the threaded rod 4 is rotatably connected to the right inner wall of the pulping chamber 1, and the other end passes through the cleaning ring 41 and the left side wall of the pulping chamber 1 in sequence, and is fixedly connected to the first gear 42. The connection between the cleaning ring 41 and the threaded rod 4 is a threaded connection. By rotating the first gear 42, the cleaning ring 41 is driven to move laterally in the pulping chamber 1, scraping off the residue adhering to the inner wall of the pulping chamber 1. There is no need to open the chamber for cleaning, making the operation convenient and labor-saving. A sliding rod 46 is horizontally fixedly connected inside the pulping chamber 1, with its two ends fixed to the left and right inner walls of the pulping chamber 1, respectively. The cleaning ring 41 is slidably connected to the sliding rod 46, guiding its horizontal back-and-forth movement. A first gear 42 meshes with a second gear 44, which is rotatably connected to the outer wall of the pulping chamber 1. The diameter of the first gear 42 is smaller than that of the second gear 44. Rotating the second gear 44 drives the first gear 42 to rotate, making operation more dynamic. A second handle 45 can be fixedly installed at the eccentric position of the second gear 44, making cleaning work more labor-saving and convenient. A brush is fixedly connected to the center of the cleaning ring 41. While the cleaning ring 41 slides horizontally back and forth, it cleans the blades of the spiral stirring rod 22.

[0048] Example 4

[0049] The paper pulper with automatic feeding function in this embodiment has the same basic structure as in embodiment 3, with the following differences or improvements: Figure 6 , 7 As shown, the blade 65 is inclined downwards, with an inclination angle of 'a' at its far end. This creates a triangular cross-section space between the blade 65 and the screen plate 64 for crushing and extrusion, ensuring smoother material flow during the buffered extrusion of the crushed material through the screen plate 64 holes. Preferably, the blade 65 is inclined in two stages, with the inclination angle of the middle section being 'b', greater than the inclination angle of the far end 'a'. This two-stage buffered extrusion further prevents motor overload due to material blockage. The inclination angles 'a' and 'b' are: 5°≤a≤10°, 12°≤b≤20°, preferably a=10° and b=18°. This ensures both crushing efficiency and immediate material discharge from the screen plate 64 holes. The screen plate 64 holes are preferably arranged radially from the center to the edges, achieving a division of labor where edge crushing and central discharge occur within the two-stage triangular crushing and extrusion space. This synchronizes crushing and discharge as much as possible, preventing material accumulation and blockage.

[0050] Example 5

[0051] The paper pulper with automatic feeding function in this embodiment has the same basic structure as in embodiment 3, but the difference or improvement is that it includes a pulping bin 1, a first connecting bin 2, a sealing bin door 3, a threaded rod 4, a second connecting bin 5, and a crushing bin 611. The first connecting bin 2 is provided on one side of the pulping bin 1. The sealing bin door 3 extending into the pulping bin 1 is sleeved on the right side of the pulping bin 1. The threaded rod 4 is arranged horizontally inside the pulping bin 1. The second connecting bin 5 is fixed to the upper part of the pulping bin 1. The crushing bin 611 extending into the pulping bin 1 is also provided on the upper part of the pulping bin 1. The second motor 51 is installed inside the second connecting bin 5. The feeding bin 52 extending into the crushing bin 61 is provided on the right side of the second connecting bin 5.

[0052] See Figure 1 , 2 As can be seen from points 4 and 8, the upper part of the feeding bin 52 is provided with a feeding pipe 53 extending into the inside of the feeding bin 52, and the output end of the second motor 51 is fitted with a feeding screw rod 54 extending into the inside of the feeding bin 52.

[0053] In practice, when the paper pulper needs to be fed, the operator pours the raw material into the feeding bin 52 through the feed pipe 53. The operator then turns on the second motor 51, and the output end of the second motor 51 rotates, driving the feeding screw 54 to rotate. The rotation of the feeding screw 54 drives the raw material into the groove on the outside of the feeding screw 54. The rotation of the feeding screw 54 pushes the raw material to move laterally inside the feeding bin 52, pushing it into the crushing chamber 61. By setting up the second motor 51, feeding bin 52, feed pipe 53, and feeding screw 54, the raw material is pushed into the crushing chamber 61 for the next process. This allows the paper pulper to automatically feed the material, while preventing the raw material from splashing inside the paper pulper, facilitating its entry into the next process. The semi-automatic and stable feeding of raw materials reduces the cost of manual supervision. At the same time, the structure is simple, the cost is low, and the maintenance is convenient.

[0054] See Figure 1 , 2 As can be seen from 3, 4 and 6, a vertical third connecting chamber is provided at the upper part of the crushing chamber 61. A third motor 62 is installed inside the third connecting chamber. A rotating shaft 63 extending into the crushing chamber 61 is sleeved at the output end of the third motor 62. A screen plate 64 is provided on the inner wall at the bottom of the crushing chamber 61. A blade 65 is sleeved at the bottom end of the rotating shaft 63.

[0055] In practice, when raw materials need to be crushed, the feeding screw 54 rotates to push the raw materials into the crushing chamber 61. The operator starts the third motor 62, and the output of the third motor 62 drives the rotating shaft 63 and the blades 65 to rotate. After the blades 65 crush the raw materials, the screen plate 64 screens the crushed material. At the same time, the output of the second motor 51 drives the feeding screw 54 to continuously push the raw materials into the crushing chamber 61, rapidly pushing the crushed material inside the crushing chamber 61. The raw material is crushed by the blades 65, and the resulting powder falls through the screen plate 64 into the pulping bin 1 for the next process. The solid raw material is then fully crushed. The crushed powder is easier to pulp inside the pulping bin 1. Solution is injected into the pulping bin 1 through the injection pipe 13. The crushed raw material is mixed with the solution, which effectively improves the pulping efficiency of the paper pulper and the working efficiency of the paper pulper. It also facilitates the uniform mixing of the fiber in the powder with the solution, making the pulp content and color in the solution more uniform.

[0056] See Figure 1 , 2 As can be seen from points 3 and 4, a support column 11 is fixedly connected to the bottom of the pulping bin 1, a discharge pipe 12 extending to the outside of the bottom of the pulping bin 1 is provided inside the pulping bin 1, and a liquid injection pipe 13 extending to the outside of the upper part of the pulping bin 1 is provided inside the pulping bin 1.

[0057] In practice, the pulp from the paper pulper is fed through the feed pipe 12, which is equipped with a valve. The solution required for the pulp is injected into the pulp bin 1 through the injection pipe 13, so that the solution and the pulp can be mixed to form pulp.

[0058] See Figure 2 It is known that a first motor 21 is installed inside the first connecting chamber 2, and a spiral stirring rod 22 extending into the pulping chamber 1 is sleeved at the output end of the first motor 21.

[0059] In practice, when it is necessary to stir and pulp the solution and material, the operator turns on the first motor 21. The output end of the first motor 21 drives the spiral stirring rod 22 to rotate inside the pulping chamber 1. The rotation of the spiral stirring rod 22 stirs the solution and material inside the pulping chamber 1, so that the material dissolves into fibers in the solution and the material and solution form pulp.

[0060] See Figure 1 , 2As can be seen from 3, the sealed chamber door 3 is provided with a bolt 31 that passes through the right outer wall of the sealed chamber door 3 and connects to the pulping chamber 1. The bolt 31 is screwed with a nut 32. The outer side of the sealed chamber door 3 is provided with a first handle 33. A limiting groove 34 is opened on the side of the sealed chamber door 3 away from the first handle 33. The limiting groove 34 is rotatably connected to the right end of the spiral stirring rod 22.

[0061] In practice, when the operator needs to inspect the interior of the pulping chamber 1, the operator separates the nut 32 from the bolt 31 by screwing them together. The operator then opens the sealing chamber door 3 using the first handle 33. The movement of the sealing chamber door 3 causes the limiting groove 34 to separate from the right end of the spiral stirring rod 22, allowing the operator to inspect the interior of the pulping chamber 1. By setting up the sealing chamber door 3, bolt 31, nut 32, first handle 33, and limiting groove 34, the sealing chamber door 3 can be opened and closed, facilitating the operator's inspection of the interior of the pulping chamber 1. Regular inspection of the interior of the pulping chamber 1 effectively ensures the stability of the paper pulping machine's operation.

[0062] See Figure 1 , 2 As can be seen from 3, the outer wall of bolt 31 has an external thread, and the inner wall of nut 32 has an internal thread. The external thread of bolt 31 and the internal thread of nut 32 are threadedly connected.

[0063] In practice, the operator connects the nut 32 and the bolt 31 by rotating the nut 32.

[0064] See Figure 1 , 2 As can be seen from points 4 and 5, the threaded rod 4 is fitted with a cleaning ring 41, the pulp bin 1 is provided with a first gear 42 on the left outer side, and a second gear 43 is provided on one side of the first gear 42. The first gear 42 and the second gear 43 are meshed and connected.

[0065] See Figure 1 , 2 As can be seen from points 4 and 5, the second gear 43 has a connecting shaft 44 that passes through it, and a second handle 45 is provided on one side of the connecting shaft 44. The cleaning ring 41 has a sliding rod 46 that is connected to the inner wall of the pulping chamber 1. The threaded rod 4 is rotatably connected to the pulping chamber 1, and the connecting shaft 44 is rotatably connected to the pulping chamber 1.

[0066] In practice, when it is necessary to clean the inner wall of the pulp bin 1 in the paper pulper, the operator reverses the second handle 45. This reverse rotation of the second handle 45 causes the connecting shaft 44 to reverse, which in turn causes the second gear 43 to reverse. The reverse rotation of the second gear 43 then causes the first gear 42, which meshes with the second gear 43, to rotate forward. The forward rotation of the first gear 42 causes the threaded rod 4 to rotate forward, which in turn causes the cleaning ring 41 to move laterally along the rod of the threaded rod 4. The cleaning ring 41 scrapes the inner wall of the pulp bin 1. The cleaning ring 41 slides guided by the sliding rod 46, scraping the waste pulp adhering to the inner wall of the pulp bin 1. The cleaning ring 41 pushes the pulp on the inner wall of the pulp bin 1 toward the sealing door 3. The operator separates the nut 32 from the bolt 31 by screwing it. The operator opens the sealing door 3 through the first handle 33. The operator cleans the waste pulp scraped by the cleaning ring 41 and the waste pulp on the inner wall of the cleaning ring 41, making it easier to clean the waste pulp uniformly and reducing the difficulty of cleaning the waste pulp.

[0067] See Figure 1 , 2 As can be seen from points 4 and 5, a threaded hole is provided at the threaded connection between the cleaning ring 41 and the threaded rod 4, and a sliding hole is provided at the sliding connection between the cleaning ring 41 and the sliding rod 46. The cleaning ring 41 and the threaded rod 4 are threadedly connected through the threaded hole, and the cleaning ring 41 and the sliding rod 46 are slidably connected through the sliding hole.

[0068] In summary: When a paper pulper is needed to produce pulp, the operator starts the second motor 51. The output of the second motor 51 drives the feeding screw 54 to rotate, which pushes the raw material into the crushing chamber 61. The operator then starts the third motor 62. The output of the third motor 62 drives the rotating shaft 63 and blades 65 to crush the raw material. The screen plate 64 screens the crushed material, causing it to fall into the pulping chamber 1. The solution required for pulping is injected into the pulping chamber 1 through the injection pipe 13. The operator then starts the first motor 21. The output of the first motor 21 drives the spiral stirring rod 22 to rotate, which stirs the solution and material inside the pulping chamber 1, causing the material to dissolve into fibers in the solution and forming pulp. The pulp is then fed through the discharge pipe 12, completing the entire processing of the raw material.
