Description

Technical Field

[0001] This utility model belongs to the field of papermaking equipment technology, specifically, it relates to a pulp concentration adjustment device for papermaking equipment. Background Technology

[0002] A slurry concentration regulating device is an automated control device that detects the slurry concentration and automatically adjusts the amount of dilution water or other parameters to keep the slurry concentration within a set range.

[0003] Existing technology discloses a pulp concentration adjustment device for papermaking equipment (CN221118081U), including a pulp tank, a support base symmetrically fixed to the bottom of the pulp tank, a fixed plate fixed to the top of one side of the outer wall of the pulp tank, a movable groove provided on the top surface of the fixed plate, and an adjustment component inside the movable groove; a discharge port is provided at the bottom of the outer wall of the pulp tank away from the fixed plate, a drain valve is provided in the discharge port, and one end of a drain pipe is fixed to the outer end of the discharge port; an inlet is provided on the inner wall of the pulp tank above the discharge port, and one end of an input pipe is fixed to the outer end of the inlet; the adjustment component includes a servo motor, which is embedded in one side of the inner wall of the movable groove, one end of the servo motor drive is fixed to one end of a lead screw, and the other end of the lead screw is rotatably connected to the other side of the inner wall of the movable groove. This utility model can adjust the water addition position and, in conjunction with a stirring rod, quickly and evenly stir the pulp, improving the efficiency of pulp concentration adjustment.

[0004] Research revealed that the pulp concentration is related to the mixing ratio between paper fibers and water. Existing technology does not consider whether the size of the paper fibers can fully integrate with the water. This results in excessively large paper fibers not being able to fully integrate with the water, thus affecting the pulp concentration ratio. Furthermore, when the pulp concentration is too low, existing technology cannot extract water from the pulp, requiring the addition of paper fibers. This method has certain drawbacks, leading to excessive pulp in the later stages and causing waste.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] A pulp concentration adjustment device for papermaking equipment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the system includes an adjustment box 10, which is fixedly placed on the ground, with a cover plate 12 snapped onto its top surface; a mixing filter structure, which is rotatably disposed within the cover plate 12, comprising an agitator 19, a crushing filter cylinder 21, and a crushing blade roller 24. The agitator 19 is rotatably disposed on the inner bottom surface of the adjustment box 10, the crushing filter cylinder 21 is fixedly disposed inside the adjustment box 10, and the crushing blade roller 24 is rotatably disposed within the cover plate 12 and the crushing filter cylinder 21, and is movably disposed above the agitator 19; and a water absorption structure, which is fixedly disposed inside the adjustment box 10, comprising a screw 29, a side column 30, a folding curtain 32, a lifting seat 33, and a sponge 35. The side column 30 is fixedly disposed inside the adjustment box 10, the screw 29 is rotatably disposed inside the side column 30, the folding curtain 32 and the lifting seat 33 are both slidably disposed within the side column 30, the screw 29 is threaded within the lifting seat 33, and the sponge 35 is movably disposed within the lifting seat 33.

[0030] The working principle is as follows: By setting up a mixing and filtering structure in this device, the paper fibers are crushed by the crushing roller 24. Paper fibers of suitable size pass through the crushing filter cylinder 21 and enter the regulating box 10. Then, the stirring paddle 19 mixes the paper fibers and water evenly, thus avoiding the situation where excessively large paper fibers cannot be completely mixed with water, resulting in uneven pulp ratio. By setting up a water absorption structure, the lifting seat 33 is raised and lowered by the screw 29. While the lifting seat 33 is rising and falling, it squeezes out the excess water from the paper fibers. Then, the water is absorbed and retained by the sponge 35. During this process, the folding curtain 32 folds and unfolds along with the movement of the lifting seat 33 to prevent paper fibers from entering the side column 30 and adhering to the screw 29, causing problems. Finally, the sponge 35 is taken out through the water inlet, which can adjust the pulp concentration and avoid the situation where the concentration is too dilute, thus avoiding the waste caused by excessive pulp.

[0031] like Figure 1 and Figure 2 As shown, the adjustment box 10 has a square box structure. A retaining edge 18 is fixedly connected to the top surface of the adjustment box 10. The cover plate 12 consists of a square plate and a square ring, with the retaining edge 18 engaging within the square ring. Figure 1 , Figure 2 and Figure 3 As shown, a discharge pipe 11 is fixedly connected to one side of the regulating box 10. A detection hole 14 is opened on one side of the regulating box 10. The discharge pipe 11 is located directly below the detection hole 14. A concentration monitor 15 is snapped into the detection hole 14. A fixing plate 16 is fixedly connected to the top surface of the concentration monitor 15 by bolts. The fixing plate 16 fixes the regulating box 10 and the concentration monitor 15. A water inlet pipe 13 and a feed inlet 26 are fixedly connected to the top surface of the cover plate 12. Figure 1 and Figure 2 As shown, the crushing filter cylinder 21 consists of a cross ring and a cylinder. The cross ring is fixedly connected to the inner wall of the adjusting box 10, and a filter plate 22 is fixedly connected inside the cylinder. Both the cover plate 12 and the filter plate 22 have circular holes at their centers, and the crushing roller 24 is rotatably connected to these holes via bearings. Figure 1 , Figure 2 and Figure 3 As shown, a fixed column 17 is fixedly connected to the bottom surface of the regulating box 10, a rotating groove 36 is opened on the bottom surface of the stirring paddle 19, the fixed column 17 is rotatably connected in the rotating groove 36, a slot 20 is opened on the top surface of the stirring paddle 19, and a locking block 23 is fixedly connected to the bottom surface of the crushing roller 24, the locking block 23 is locked in the slot 20.

[0032] The working principle is as follows: When in use, the discharge pipe 11 is first blocked to prevent slurry leakage. Alternatively, a check valve can be installed as needed. Specifically, material is added into the crushing filter cylinder 21 through the feed pipe 26. The crushing roller 24 crushes the material. The crushed material is filtered through the filter plate 22 and reaches the regulating box 10. At this time, clean water is added through the water inlet pipe 13. The stirring paddle 19 stirs and mixes the material and water. The mixed slurry is then drawn into the concentration detector 15 through the detection hole 14. The concentration detector 15 then detects the concentration. If the concentration is appropriate, the slurry can be taken out. If the concentration is not appropriate, water can be added or water can be absorbed as needed.

[0033] like Figure 1 and Figure 4 As shown, a fan-shaped side post 30 is fixedly connected to one corner of the inside of the adjusting box 10. A through hole is opened inside the side post 30, and a screw rod 29 is rotatably connected inside the through hole. An arc-shaped groove is opened on the curved side of the side post 30, and two folding curtains 32 are slidably arranged in the arc-shaped groove. The two folding curtains 32 are fixedly connected to the two side planes of the lifting seat 33 respectively. The side of the two folding curtains 32 away from the lifting seat 33 is fixedly connected to the two end walls of the arc-shaped groove respectively. A threaded hole is opened at one end of the lifting seat 33 near the screw rod 29, and the screw rod 29 is threadedly connected in the threaded hole. A water filter trough 34 is opened at the other end of the lifting seat 33, and a sponge 35 is placed in the water filter trough 34.

[0034] The working principle is as follows: When the pulp concentration is too diluted, the lead screw 29 rotates, and the rotation of the lead screw 29 pushes the lifting seat 33 to rise and fall. When the lifting seat 33 falls, one of the folding curtains 32 located above the lifting seat 33 slides down, and the other folding curtain 32 located below the lifting seat 33 squeezes down. At this time, the lifting seat 33 squeezes the paper fibers in the pulp, so that the excess water in the paper fibers is absorbed by the sponge 35 through the filter tank 34. When the lead screw 29 rotates in the opposite direction, it drives the lifting seat 33 to rise. At this time, the two folding curtains 32 follow the lifting seat 33 to move upward. When the lifting seat 33 approaches the water inlet 27, the sponge 25 is taken out, and the pulp concentration is detected again by the concentration detector 15. The water absorption operation is repeated again according to the concentration, or clean water is added by the water inlet pipe 13 for dilution.

[0035] like Figure 3 and Figure 4As shown, a water inlet 27 is provided on the top surface of the cover plate 12. The water inlet 27 is located directly above the side column 30. A bracket 31 is fixedly installed on the top surface of the side column 30 by bolts. There are two brackets 31 with different sizes. A lifting motor 28 is fixedly installed on the side column 30 through one of the smaller brackets 31. The output end of the lifting motor 28 is connected to the top surface of the lead screw 29. Another larger bracket 31 is fixedly installed on the top surface of the cover plate 12 by bolts. A rotating motor 25 is fixedly installed inside the other larger bracket 31. The output end of the rotating motor 25 is connected to the top surface of the crushing roller 24.

[0036] The specific implementation method is as follows: First, the discharge pipe 11 is blocked by a plug. Material is added into the crushing filter cylinder 21 through the feed pipe 26. The rotating motor 25 is started, which drives the crushing roller 24 and the stirring paddle 19 to rotate. The crushing roller 24 crushes the material. After crushing, the material of suitable size is filtered through the filter plate 22 and enters the regulating box 10. At this time, clean water is added through the water inlet pipe 13. The stirring paddle 19 stirs and mixes the material and water. The mixed slurry is then sucked up by the concentration detector 15 through the detection hole 14. The concentration detector 15 then detects the concentration. If the concentration is suitable, the slurry can be taken out through the discharge pipe 11. If the concentration is not suitable, water absorption treatment is required. The lifting motor 28 is started, which drives the rotation of the lead screw 29. The lead screw 29 pushes the lifting motor 28 to rotate. As the lifting seat 33 descends, the folding curtains 32 located on the upper and lower sides of the lifting seat 33 move accordingly, blocking the pulp outside the side column 30. At this time, the lifting seat 33 squeezes the paper fibers in the pulp, so that the excess water in the paper fibers is absorbed by the sponge 35 through the filter tank 34. The lifting motor 28 is started in reverse. It should be noted that the lifting motor 28 is connected to an external control power supply, which controls the forward and reverse rotation of the lifting motor 28. When the lead screw 29 rotates in reverse, it drives the lifting seat 33 to rise. At this time, the two folding curtains 32 move upward with the lifting seat 33. When the lifting seat 33 approaches the water inlet 27, the sponge 25 is taken out, and the pulp concentration is detected again by the concentration detector 15. The water absorption operation is repeated again according to the concentration, or clean water is added by the water inlet pipe 13 for dilution.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
