The axial reciprocating motion of the stirring rod can form a longitudinal vortex to enhance the diffusion of the agent, thereby improving the mixing efficiency, shortening the reaction cycle, and reducing energy loss.

[0019] Optionally, one of the infusion tubes is a hose, a return spring is fixed between the outer surface of the plug rod and the bottom side of the plug barrel, the width of the lifting platform is adapted to the position of the plug rod, and the bottom end of the plug rod is located directly above the lifting platform.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1.

[0029] The following is combined with Figures 1 to 7 This application is described in further detail.

[0030] The present application discloses a device for treating waste pulp residue used in base paper production. Figures 1 to 7 A waste pulp treatment device for base paper production includes a waste pulp treatment device 1 for base paper production, the waste pulp treatment device 1 includes a treatment tank 11, and a stirring assembly is provided inside the treatment tank 11. Specifically, the stirring assembly includes a transmission sleeve 12 rotatably mounted inside the treatment tank 11, and a stirring rod 13 extending outside the treatment tank 11 is provided inside the treatment tank 11. The stirring rod 13 passes through the transmission sleeve 12 and is spline-connected to the transmission sleeve 12. A sleeve 15 is rotatably mounted on the top of the stirring rod 13, and an infusion cavity 14 for use with an infusion structure 7 is provided inside the stirring rod 13. It should be noted that the spline-connected transmission sleeve 12 and stirring rod 13 can allow the stirring rod 13 to move up and down along the axial direction while rotating, so that the stirring rod 13 can stir at different depths in the treatment tank 11, break up the slurry stratification, and improve the mixing uniformity.

[0031] Furthermore, the infusion chamber 14 within the stirring rod 13 is directly connected to the infusion function above. The drug is injected into the infusion chamber 14 through the infusion function and ultimately released directly into the slurry from the bottom or side wall of the stirring rod 13 (not shown in the figure), but this is generally a design key. This prevents the drug from remaining on the surface or in the upper layer, achieving deep, precise, and uniform drug addition, greatly improving reaction efficiency and effectiveness.

[0032] In order to improve the waste slurry treatment effect, an automatic adding device 4 for use with a stirring assembly is provided on the top side of the treatment tank 11, and a driving device 3 for use with the automatic adding device 4 is installed on the side wall of the treatment tank 11; the automatic adding device 4 includes a driving assembly 5, a liquid storage structure 6 and an infusion structure 7 arranged above the treatment tank 11; the driving assembly 5 includes a sliding frame 51, a first rack 52 is fixed to one side of the sliding frame 51, and the outside of the first rack 52 is engaged with a first gear 53 connected to the stirring assembly, a lifting platform 54 is provided above the sliding frame 51, and a connecting sleeve 57 connected to the stirring assembly is installed on one side of the lifting platform 54, a sliding seat 55 is provided in the sliding frame 51, and a connecting rod 56 is hinged between the sliding seat 55 and the lifting platform 54. Specifically, first gear 53 is fixed to the outer surface of transmission sleeve 12. The rotation of stirring rod 13 is driven by transmission sleeve 12. The first gear 53 engages with first rack 52, driving slide 51. This, in turn, drives lifting platform 54 and connecting sleeve 57 through connecting rod 56 and other mechanisms, ultimately driving the rotation of transmission sleeve 12. Axial lifting is directly driven by the up-and-down motion of lifting platform 54. Both of these motions originate from the same drive source, namely drive device 3. These two motions are cleverly integrated through linkage assembly 9 and drive assembly 5, achieving strict synchronization of stirring rotation and lifting with drug addition, efficient power utilization, and a simplified transmission structure.

[0033] To achieve the reciprocating motion of the stirring rod 13, the inner side of the connecting sleeve 57 is fixedly connected to the outer surface of the sleeve 15. A guide rod 58 is fixed to the inner top wall of the mounting cover 2 and extends through the interior of the lifting platform 54. A buffer spring 59 is fixed between the inner top wall of the mounting cover 2 and the lifting platform 54 and surrounds the outer side of the guide rod 58. The guide rod 58 extends through the lifting platform 54, providing precise vertical guidance for the vertical linear motion of the lifting platform 54. This ensures that the movement trajectory of the lifting platform 54 is strictly vertical and does not deflect, ensuring that the force applied to the connecting sleeve 57 and the sleeve 15 is uniform and stable.

[0034] To ensure stable adjustment, a stopper 510 is fixed to the inner sidewall of the mounting cover 2 to limit the position of the sliding frame 51. The interior of the sliding frame 51 is hollow, and a slider 511 is fixed to the sidewall of the sliding frame 51, which is slidably connected to the stopper 510. The slider 55 is slidably mounted on the top side of the stopper 510. Specifically, the stopper 510 fixed to the inner sidewall of the mounting cover 2 provides a forced directional sliding track for the sliding frame 51, ensuring that the movement path of the sliding frame 51 is strictly limited to a straight line, preventing horizontal deflection or twisting during operation. This ensures that the meshing position of the first rack 52 and the first gear 53 is always maintained accurately, avoiding gear rack misalignment, tooth skipping, or abnormal wear caused by the shaking of the sliding frame 51.

[0035] In order to realize the linkage between stirring and infusion, the infusion structure 7 includes a plug barrel 71, a first piston 72 is provided inside the plug barrel 71, a plug rod 73 extending to the outside of the plug barrel 71 is fixed on the bottom side of the first piston 72, and the bottom end of the plug rod 73 intermittently abuts against the top side of the lifting platform 54; a mounting cover 2 with a hollow interior is fixed on the top side of the processing tank 11, and the drive assembly 5 and the infusion structure 7 are both arranged inside the mounting cover 2. The mounting cover 2 integrates and encapsulates precision moving parts such as the drive assembly 5 and the infusion structure 7 in a rigid hollow mounting cover 2, providing a stable mounting base and operating environment for the entire automatic adding system, effectively isolating external vibrations and interference. It should be noted that the bottom end of the plug rod 73 intermittently abuts against the top side of the lifting platform 54. This means that only when the lifting platform 54 rises to a specific height or is in a specific position will the plug rod 73 be lifted, thereby driving the first piston 72 to move to generate negative pressure suction or downward pressure discharge. This design directly links the trigger point of the drug addition with the lifting position of the stirring rod 13, thereby achieving a strong correlation between the drug addition and the stirring action.

[0036] In this embodiment, the automatic adding device 4 also includes a linkage component 9 for transmitting the drive of the driving device 3, so that the driving component 5 and the liquid storage structure 6 are used in conjunction with each other, and a boosting structure 8 is provided on one side of the infusion structure 7 for use in conjunction.

[0037] The linkage assembly 9 comprises a reciprocating plate 91 mounted on the exterior of the treatment tank 11. An inclined slot 92 is defined within the reciprocating plate 91. A roller 93 is rotatably mounted within the slot 92. A linkage shaft 94, which extends into the mounting cover 2 and is fixed to one side of the slide frame 51, is rotatably mounted within the roller 93. The bottom side of the reciprocating plate 91 is fixed to the output end of the drive device 3. The coordination between the inclined slot 92 and the roller 93 efficiently converts the rotary motion of the drive device 3 into the reciprocating linear motion of the slide frame 51. This, by extending the travel of the drive device 3, increases the displacement of the slide frame 51, thereby driving the movement of the slide 55 and actively triggering the lifting platform 54 to rise and fall via the connecting rod 56. This dynamically links the dosing action with the stirring intensity, enabling automatic dosing when stirring is high and preventing ineffective dosing. It should be noted that the shape of the linkage shaft 94 can be modified as needed. Furthermore, a limiting guide rail can be installed on the outer wall of the treatment tank 11 to limit the position of the reciprocating plate 91.

[0038] To achieve the infusion function, the liquid storage structure 6 includes a liquid storage tank 61 fixed to the side wall of the mounting cover 2. A stirring shaft 62 is rotatably mounted within the liquid storage tank 61. A second gear 63 is fixed to one end of the stirring shaft 62, and a second rack 64 is meshed with the exterior of the second gear 63. A connecting arm 95, fixed to the outer wall of the reciprocating plate 91, is mounted to the second rack 64. This application utilizes the reciprocating motion of the reciprocating plate 91 as power input, driving the second rack 64 to translate via the connecting arm 95, which in turn drives the second gear 63 to rotate. This design eliminates the need for an additional motor, allowing the rotational power of the stirring shaft 62 to be directly derived from the main drive device 3, improving energy utilization. The rotational motion of the stirring shaft 62 and the displacement motion of the reciprocating plate 91 form temporal and spatial coordination. When the reciprocating plate 91 pushes the sliding frame 51 to operate, the liquid in the liquid storage tank 61 is stirred synchronously, effectively preventing drug precipitation or stratification. A movable hole is provided within the mounting cover 2, and a structure is installed within the movable hole to limit the linkage shaft 94, further stabilizing its transmission.

[0039] The plug barrel 71 is fixed to the inner top wall of the mounting cover 2. The outer surface of the plug barrel 71 is fixedly connected to two check valves 75. The two check valves 75 are installed with an infusion tube 76 at one end. The two infusion tubes 76 are fixedly connected to the sleeve 15 and the liquid storage tank 61 at one end. The reciprocating motion of the plug barrel 71 of the present application is driven by the linkage assembly 9 to form an alternating volume chamber. In conjunction with the unidirectional conduction characteristics of the two check valves 75, the treatment liquid in the liquid storage tank 61 is pumped into the sleeve 15. In conjunction with the axial reciprocating motion of the stirring rod 13, a longitudinal vortex can be formed to enhance the diffusion of the agent, thereby improving the mixing efficiency, shortening the reaction cycle, and reducing energy loss. Specifically, one of the infusion tubes 76 is a hose. A return spring 74 is fixed between the outer surface of the plug rod 73 and the bottom side of the plug barrel 71. The width of the lifting platform 54 is adapted to the position of the plug rod 73, and the bottom end of the plug rod 73 is located directly above the lifting platform 54. A hose is used as the infusion tube 76, and the elastic potential energy storage and release mechanism of the return spring 74 is used to convert the intermittent lifting motion of the lifting platform 54 into a continuous reciprocating motion of the plug rod 73, thereby achieving energy optimization.

[0040] The boost structure 8 includes a mounting base 81, the internal thread of the mounting base 81 is installed with a knob 82 extending into the interior of the mounting cover 2, the bottom end of the knob 82 is fixed with an adjusting rod 83, and the bottom end of the adjusting rod 83 is installed with a second piston 84 extending into the interior of the sleeve 15. When the stirring rod 13 reciprocates, the second piston 84 can adjust the volume of the cavity, thereby generating a pulsed pressure wave to achieve boosted injection, using high-pressure jets to penetrate high-viscosity slurries to avoid surface floating, and the pulse pressure flushes the nozzle of the stirring rod 13 to achieve the advantage of anti-clogging. The mounting base 81 is bolted to the top side of the mounting cover 2, and the bottom end of the adjusting rod 83 is rotatably connected to the second piston 84. The knob 82 is threadedly matched with the mounting base 81 to adjust the position of the second piston 84, and then to adjust the volume of the adjustment cavity to improve the boost effect.

[0041] It is worth mentioning that the synergistic effect of the boosting structure 8 further increases the pressure or flow of the injected agent. Combined with the design of the hollow stirring rod 13, the pressurized agent can more effectively penetrate the thick waste slurry, overcome resistance, and reach the bottom of the treatment tank 11 or the target area, thereby enhancing the mixing contact effect between the agent and the slurry, especially when treating high-concentration and high-viscosity waste slurry.

[0042] Combined with attachment Figures 1 to 7 , the working principle of the above embodiment is as follows: First, the driving device 3 pushes the reciprocating plate 91 to perform linear motion. The oblique slide 92 converts the linear motion of the reciprocating plate 91 into lateral displacement of the linkage shaft 94, driving the sliding frame 51 to slide left and right. The displacement of the sliding frame 51 drives the first gear 53 to rotate through the first rack 52, which in turn drives the transmission sleeve 12 to rotate, thereby driving the stirring rod 13, thereby processing the base paper waste pulp inside the processing tank 11. When medication is required, the output distance of the driving device 3 is extended, so that the displacement of the sliding frame 51 becomes longer. When the sliding frame 51 is extended, its inner side will abut against the outer wall of the sliding seat 55, thereby driving the sliding seat 55 to move and pushing the lifting platform 54 up and down through the connecting rod 56; The lifting platform 54 rises to lift the plug rod 73, pulling the first piston 72 upward, forming a negative pressure in the plug barrel 71, and cooperating with the opening and closing of the two check valves 75, so that the liquid medicine in the liquid storage tank 61 is sucked into the plug barrel 71 through the infusion tube 76. The lifting platform 54 descends, and the liquid medicine is injected into the sleeve 15 through another infusion tube 76 and enters the infusion cavity 14 inside the stirring rod 13 and is discharged, thereby directly reaching the interior of the waste slurry. At the same time, the up and down movement of the lifting platform 54 will drive the stirring rod 13 to reciprocate up and down, thereby realizing the rotation and axial reciprocating compound movement of the stirring rod 13, thereby improving the dosing effect; In addition, when the stirring rod 13 reciprocates up and down, the adjusting rod 83 pushes the second piston 84 to move up and down in the sleeve 15 to change the volume of the infusion cavity 14, control the ejection pressure of the liquid medicine, further deliver the medicine, realize binary medicine pressure delivery, and uniformly place the medicine in the treatment tank 11.

[0043] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, and: all equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
