Description

Technical Field

[0001] This utility model relates to the field of paper production technology, and in particular to a pulp mixing device for paper production. Background Technology

[0002] In the paper industry, base paper production is a crucial foundational step, and pulp blending, as one of the core processes in base paper production, directly affects the quality and performance of the base paper. High-quality, uniform pulp blending ensures that the base paper possesses stable key indicators such as strength and smoothness, which is of great significance for improving the production efficiency and product competitiveness of paper manufacturing enterprises.

[0003] Currently, most existing pulp mixing devices for paper production employ traditional stirring methods, using ordinary agitators to agitate the pulp within a mixing tank. During the mixing process, it is difficult for the pulp to achieve sufficient vertical convection, often resulting in insufficient mixing at the bottom, leading to low mixing efficiency and inconsistent quality. Furthermore, for additives, most devices add all the additives into the mixing tank at once. Due to limitations in pulp fluidity and stirring methods, the additives cannot be quickly and evenly dispersed in the pulp, easily causing localized excessively high or low additive concentrations. This not only wastes additives but also makes the produced paper unstable in performance. To address these technical problems, this application proposes a pulp mixing device for paper production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pulp mixing device for paper production. A motor drives a rotating rod to rotate an inclined tubular mixing tube, causing the pulp at the bottom to flow from the bottom to the top of the tube, achieving bottom-to-top pulp conveying. This dynamic conveying method breaks through the limitations of traditional mixing, allowing the pulp to form more thorough convection and circulation within the mixing tank, avoiding uneven mixing in certain areas, and significantly improving mixing efficiency and quality. When the rotating rod rotates, it drives a drive gear to mesh with a driven gear, causing the annular wedge to rotate. This wedge structure intermittently lifts the support rod, driving the moving tube up and down. Additives are added when the moving tube enters the storage box and stop when it leaves, avoiding excessive addition at once and ensuring that the additives are gradually and evenly mixed with the pulp, enhancing the mixing effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A pulp mixing device for paper production includes a mixing tank. A fixed pipe is fixedly connected to the outer periphery of the top of the mixing tank. A storage box is fixedly connected to the top of the fixed pipe. A fixed plate is fixedly connected to the inner wall of the storage box. A movable pipe is arranged inside the fixed pipe. A through groove is opened on the outer wall of the movable pipe. A lifting component is arranged on the outer wall of the movable pipe. A rotating rod is rotatably connected to the middle of the mixing tank. A driving component is arranged at the top of the rotating rod. A connecting plate is fixedly connected to the outer wall of the rotating rod. A stirring pipe is fixedly connected to the end of the connecting plate away from the rotating rod. A feeding pipe is fixedly connected to the bottom of the mixing tank.

[0007] Furthermore, the lifting assembly includes a support rod fixedly connected to the outer wall of the moving tube, and an annular wedge is provided at one end of the support rod from the moving tube. A driven gear is fixedly connected to the bottom of the annular wedge.

[0008] Furthermore, the drive assembly includes a second motor located at the top of the rotating rod. The non-driving end of the second motor is connected to the mixing tank, and the driving end of the second motor is fixedly connected to the top of the rotating rod. A drive gear is fixedly connected to the top of the outer wall of the rotating rod, and the drive gear meshes with the driven gear.

[0009] Furthermore, a spring is provided at the top of the movable tube, one end of the spring is connected to the top of the movable tube, and the other end of the spring is connected to the middle of the bottom end of the fixed plate.

[0010] Furthermore, the outer wall of the fixed tube is provided with a movable groove, and the support rod is located in the movable groove.

[0011] Furthermore, multiple support legs are fixedly connected to the bottom outer periphery of the mixing tank.

[0012] Furthermore, a feed inlet is fixedly connected to the top outer wall of the mixing tank.

[0013] Furthermore, the outer wall of the storage box is provided with scale lines.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the rotating rod driven by the second motor rotates, which drives the inclined tubular stirring tube to rotate, so that the pulp at the bottom flows from the tube to the top, realizing the conveying of pulp from bottom to top. This dynamic conveying method breaks the limitations of traditional stirring, allowing the pulp to form more sufficient convection and circulation in the mixing tank, avoiding uneven local mixing, and significantly improving mixing efficiency and quality.

[0016] 2. In this invention, when the rotating rod rotates, it drives the driving gear to mesh with the driven gear, causing the annular wedge to rotate. The wedge structure intermittently lifts the support rod, driving the moving tube to move up and down. Additives are added when the moving tube enters the storage box and stop when it leaves, avoiding adding too much at once and ensuring that the additives are gradually and evenly mixed with the pulp, thus enhancing the mixing effect.

[0022] 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.

[0023] Reference Figure 1-3This utility model provides an embodiment of a pulp mixing device for paper production, comprising a mixing tank 1, a fixed pipe 8 fixedly connected to the outer periphery of the top of the mixing tank 1, a storage box 7 fixedly connected to the top of the fixed pipe 8, the storage box 7 being used to store additives, a fixed plate 15 fixedly connected to the inner wall of the storage box 7, a movable pipe 17 being provided inside the fixed pipe 8, and a through groove being formed on the outer wall of the movable pipe 17. When the tank groove is located inside the storage box 7, the additives in the storage box 7 can enter the movable pipe 17 through the tank groove, and then enter the pulp mixing device through the movable pipe 17. Inside the mixing tank 1, a support rod 18 is fixedly connected to the outer wall of the moving tube 17. An annular wedge 9 is provided at one end of the support rod 18, which moves the support rod 18, thus moving the moving tube 17. A driven gear 10 is fixedly connected to the bottom of the annular wedge 9, which rotates to rotate the annular wedge 9. A rotating rod 14 is rotatably connected to the middle of the mixing tank 1. A second motor 5 is provided at the top of the rotating rod 14. The non-driving end of the second motor 5 is connected to the mixing tank 1, and the driving end of the second motor 5 is connected to the rotating rod. The top of rod 14 is fixedly connected to a motor 5, which drives the rotating rod 14 to rotate. A drive gear 11 is fixedly connected to the top of the outer wall of the rotating rod 14, and the drive gear 11 meshes with the driven gear 10. The rotation of the rotating rod 14 can rotate the drive gear 11, and also rotate the stirring tube 12 via a connecting plate 13. A connecting plate 13 is fixedly connected to the outer wall of the rotating rod 14, and a stirring tube 12 is fixedly connected to the end of the connecting plate 13 away from the rotating rod 14. When the stirring tube 12 rotates around the rotating rod 14, because the stirring tube 12 is inclined... Furthermore, it is tubular. When the mixing tube 12 rotates around the rotating rod 14, the pulp at the bottom of the mixing tube 12 will flow from the inside of the mixing tube 12 to the top of the mixing tube 12, thereby conveying the pulp from the bottom to the top, which greatly improves the efficiency and quality of pulp mixing. The bottom end of the mixing tank 1 is fixedly connected to the feeding pipe 3, and the feeding pipe 3 is equipped with an auger. The outer wall of the feeding pipe 3 is equipped with a motor 4. The drive end of the motor 4 is fixedly connected to the auger. The motor 4 can drive the auger to rotate, thereby conveying the pulp in the mixing tank 1 out.

[0024] Reference Figure 1-3The moving tube 17 has a spring 16 at its top. One end of the spring 16 is connected to the top of the moving tube 17, and the other end is connected to the middle of the bottom of the fixed plate 15. When the moving tube 17 moves upward, it compresses the spring 16. When the spring 16 returns to its original position, it pushes the moving tube 17 downward, causing the groove on the outer wall of the moving tube 17 to move out of the storage box 7. The outer wall of the fixed tube 8 has a moving groove, and the support rod 18 is located in the moving groove. When the support rod 18 is at the bottom of the moving groove, the groove on the outer wall of the moving tube 17 is completely inside the fixed tube 8, and the groove does not intersect with the moving groove. Multiple support feet 2 are fixedly connected to the bottom periphery of the mixing tank 1. The top outer wall of the mixing tank 1 is fixedly connected to a feed inlet 6, through which pulp can enter the mixing tank 1. The outer wall of the storage box 7 is provided with scale lines, which make it easy for workers to judge the amount of additives.

[0025] Working principle: First, the pulp is fed into the mixing tank 1 through the feed port 6, and then an appropriate amount of additives are added into the storage box 7. The rotating rod 14 is driven to rotate by the motor 5. The rotating rod 14 rotates the stirring tube 12 through the connecting plate 13 on its outer wall. Since the stirring tube 12 is inclined and tubular, when the stirring tube 12 rotates around the rotating rod 14, the pulp at the bottom of the stirring tube 12 will flow from the inside of the stirring tube 12 to the top of the stirring tube 12, thereby conveying the pulp from the bottom to the top, which greatly improves the efficiency and quality of pulp mixing.

[0026] While the rotating rod 14 rotates with the stirring tube 12, it also rotates the driving gear 11 at its top. Since the driving gear 11 meshes with the driven gear 10, it can drive the driven gear 10 to rotate. Then, the driven gear 10 drives the annular wedge 9 at its top to rotate. Because the annular wedge 9 is wedge-shaped, when the bottom of the annular wedge 9 rotates to below the support rod 18, continued rotation of the annular wedge 9 will push the support rod 18 upward, causing the support rod 18 to move the moving tube 17 upward. At this time, the moving tube 17 will compress the spring 16. When the through groove on the outer wall of the moving tube 17... When the additive enters the storage box 7, it enters the moving tube 17 through the trough and then enters the mixing tank 1 from the bottom of the moving tube 17, where it mixes with the pulp. When the support rod 18 disengages from the highest point of the annular wedge 9, the spring 16 returns to its original position, causing the moving tube 17 to fall again. This causes the trough on the outer wall of the moving tube 17 to move out of the storage box 7, preventing the additive from entering the mixing tank 1. This intermittent addition of additives greatly improves the mixing effect between the additives and the pulp in the mixing tank 1, avoiding the problem of adding too much additive at once, which would prevent the additives from being fully mixed with the pulp.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
