Technical Field

[0001] This utility model relates to the field of paper production technology, specifically to a hydraulic pulper for paper production. Background Technology

[0002] Base paper, also known as processed base paper, is used for further processing into various types of paper. The properties, quality, and specifications of base paper vary depending on the processing requirements. All paper that requires processing is base paper. For example, composite paper used in printing can be called the base paper for printing processing; while the white cardboard used to make composite paper can be called the base paper for that composite paper.

[0003] The known publication number CN220746428U proposes a hydraulic pulper for paper production. Its background technology addresses the problem that "because the plant fibers used in papermaking are filamentous, some fibers easily hang on the outside of the sharp teeth, and long-term accumulation affects pulping efficiency, and cleaning the sharp teeth is inconvenient." To solve this problem, the proposed solution includes "an outer drum, a drive motor fixedly installed in the middle of the bottom surface of the outer drum, a guide fan blade fixedly connected to the top of the output shaft of the drive motor, eight support sleeves fixedly installed on the inner wall of the outer drum, a rotating shaft movably fitted inside the support sleeves, a slitting sheet fixedly installed on the outside of the rotating shaft, and a driven gear fixedly connected to the top of the rotating shaft."

[0004] However, the following problems were found in the implementation of the above technology: it is inconvenient to prevent sedimentation of the slurry during use; during the pulping process, the material is prone to aggregate and deposit at the bottom of the tank, which can affect the slurrying process and uniformity, thus reducing the pulping effect and efficiency.

[0035] The working principle and beneficial effects of this utility model are as follows:

[0036] 1. The slurry is agitated and broken up by rotating the shaft and the crushing mechanism. At the same time, the moving rod revolves around the rotating shaft and causes the ball bearings to roll along the top wall of the tank. Through the intermittent contact between the ball bearings and the arc-shaped block, and with the elastic force of the return spring, the tipping plate moves up and down repeatedly, moving the liquid at the bottom of the tank upward. This prevents the slurry from settling, ensures the fullness and uniformity of the crushing, and effectively improves the crushing effect and efficiency.

[0037] Second, the motor drives the rotating shaft to rotate, causing the crushing blade to rotate and stir the slurry for initial crushing. At the same time, the slurry can flow back and forth through the gap between the groove and the crushing roller, which allows the crushing roller to rotate and crush the material for secondary crushing, thereby further improving the crushing effect of the crushing blade.

[0049] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0050] Example

[0051] Please see Figure 1 - Figure 5 The technical solution of this utility model is as follows: A hydraulic pulper for paper production, comprising: a pulper body, the pulper body comprising: a barrel 1;

[0052] A rotating shaft 2 is rotatably connected to the top wall of the inner wall of the barrel 1, and a power component for driving the rotating shaft 2 is provided on the barrel 1;

[0053] Multiple arc-shaped blocks 3 are fixedly installed on the top wall inside the barrel 1;

[0054] A fixing block 4 is fixedly installed on the surface of the rotating shaft 2;

[0055] A movable rod 5 with a T-shaped cross-section is slidably connected to the fixed block 4;

[0056] A ball bearing 6 is located at the top of the movable rod 5 and in contact with the arc-shaped block 3;

[0057] The material-turning plate 7 is fixedly connected to the bottom end of the movable rod 5;

[0058] And a return spring 8 sleeved on the surface of the movable rod 5, with the two ends of the return spring 8 connected to the fixed block 4 and the top of the movable rod 5, respectively.

[0059] The power component includes a motor 10 fixedly installed on the top of the barrel 1, with the output end of the motor 10 movably passing through the barrel 1 and connected to the rotating shaft 2.

[0060] The pulper body also includes a crushing mechanism 9 mounted on the rotating shaft 2, which is used to pulp the material.

[0061] The technical solution provided in this embodiment is as follows: During use, the motor 10 drives the rotating shaft 2 to rotate, so that the rotating shaft 2, through the crushing mechanism 9, stirs and pulverizes the material-liquid mixture in the barrel 1. Simultaneously, during the rotation of the rotating shaft 2, the fixed block 4 drives the movable rod 5 to revolve around it, and the movable rod 5 drives the ball bearing 6 to roll along the inner top wall of the barrel 1 to reduce friction. When the ball bearing 6 contacts the arc-shaped block 3, the ball bearing 6 can roll along the arc surface of the arc-shaped block 3, so that the movable rod 5, under the action of the arc-shaped block 3... The lower compression of the return spring 8 causes the movable tilting plate 7 to move downwards. After the ball bearing 6 and the arc-shaped block 3 separate, the elastic force of the return spring 8 drives the movable rod 5 and the tilting plate 7 to move upwards and reset, so that the ball bearing 6 contacts the inner top wall of the barrel 1. In this way, the ball bearing 6 intermittently contacts the arc-shaped block 3, which causes the tilting plate 7 to move up and down repeatedly, moving the liquid at the bottom of the barrel 1 upwards. Therefore, the sedimentation of the slurry is prevented, avoiding affecting the quality of the pulping, ensuring the fullness and uniformity of the pulping, and effectively improving the pulping effect and efficiency.

[0062] Furthermore, the crushing mechanism 9 includes: multiple sets of crushing blades 901 fixedly installed on the surface of the rotating shaft 2, and multiple slots are provided on the crushing blades 901, wherein the crushing blades 901 are inclined relative to the horizontal plane;

[0063] And the crushing roller 902 that is rotatably connected inside the groove.

[0064] Specifically: During pulping, the motor 10 drives the rotating shaft 2 to rotate, thereby causing the crusher 901 to rotate and crush the material in the liquid. The crusher 901 also stirs the liquid, and during the stirring process, the liquid can flow back and forth through the gap between the trough and the crusher roller 902, which causes the crusher roller 902 to rotate and crush the material again, thereby further improving the crushing effect of the crusher 901.

[0065] Furthermore, the inside of the barrel 1 is equipped with a collision crushing mechanism 11 for assisting in pulping.

[0066] The collision crushing mechanism 11 includes: a plurality of fixed seats 1102 fixedly installed on the inner wall of the barrel 1; a rotating rod 1103 rotatably connected to the fixed seats 1102; a cutting plate 1104 fixedly installed on the surface of the rotating rod 1103; a transmission component provided on the barrel 1 for driving the rotating rod 1103; and a drive component provided on the barrel 1 for driving the transmission component.

[0067] The transmission components include: a gear ring 1101 rotatably mounted on the inner wall of the barrel 1;

[0068] And a transmission gear 1105 fixedly connected to the top of the rotating rod 1103 and meshing with the gear ring 1101.

[0069] The driving component includes: a second motor 1106 fixedly installed on the top of the barrel 1, with the output end of the second motor 1106 moving through the barrel 1;

[0070] And a power gear 1107 that is fixedly connected to the output end of motor 2 1106 and meshes with gear ring 1101.

[0071] Specifically: Motor 1106 drives the power gear 1107 to rotate, which in turn drives the gear ring 1101 to rotate. This causes the gear ring 1101 to drive multiple transmission gears 1105 to rotate, resulting in multiple rotating rods 1103 rotating synchronously. This adjusts the sharp edge of the cutting plate 1104 to a position opposite to the direction of slurry flow. During the slurry mixing and crushing process, the cutting plate 1104 collides with the slurry for secondary crushing, which further improves the crushing effect. After crushing, Motor 1106 reverses the direction of slurry flow to rotate the cutting plate 1104 to a position with the direction of slurry flow, allowing the slurry to wash and clean the cutting plate 1104.

[0072] Furthermore, the pulper body also includes: a feed pipe 101 fixedly installed on one side of the top of the barrel 1;

[0073] And multiple support legs 103 fixedly installed on the surface of the barrel body 1.

[0074] The pulper body also includes a discharge pipe 102 fixedly installed at the bottom of the barrel 1, and a valve is provided on the surface of the discharge pipe 102.

[0075] Specifically: By setting up the feed pipe 101, it is easy to add raw materials into the barrel 1; by setting up the support leg 103, the barrel 1 can be supported and fixed; and by setting up the discharge pipe 102, it is easy to discharge the pulped liquid.

[0076] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
