Description

Technical Field

[0001] This utility model belongs to the field of papermaking technology, and in particular relates to a high-efficiency pulping device for papermaking. Background Technology

[0002] Papermaking refers to the process of producing paper from raw materials such as cellulose through a series of processing steps. The pulp needs to be stirred during the papermaking process, typically using specialized pulping equipment.

[0003] For example, Chinese utility model patent with announcement number CN222160770U discloses a papermaking pulping device. In this device, during the rotation of the stirring shaft, one end of the auxiliary shaft, which is fixed by bearings on both sides of the stirring shaft, rotates independently inside the sealed transmission ring inside the barrel under the action of the fixed gear ring and the rotating gear at one end of the auxiliary shaft. This allows the stirring blades on one side to achieve the effect of fully stirring the liquid.

[0004] However, in actual use, although the device can increase the stirring effect on the pulp, air bubbles will appear in the pulp during the stirring process. These air bubbles can easily lead to uneven fiber distribution in the pulp, thus affecting the uniformity and strength of the paper. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency pulping device for papermaking. The device utilizes a structure capable of eliminating air bubbles that appear in the pulp during mixing, thereby improving paper quality.

[0006] The technical solution adopted by this utility model to solve the above problems is: a high-efficiency pulping device for papermaking, comprising:

[0007] A pulping tank, wherein a feed pipe is fixedly connected to one side of the top of the pulping tank, and a discharge pipe is fixedly connected to the center of the bottom of the pulping tank;

[0008] The defoaming assembly includes a motor fixedly connected to the center of the top of the pulping tank, and a shaft coaxially fixedly connected to the end of the motor rotor and rotatably connected inside the pulping tank.

[0009] A sleeve movably fitted onto the shaft, a tension spring disposed on the shaft and used to push the sleeve downward, a connecting frame fixedly connected to the sleeve, a ball disposed at the end of the connecting frame, a guide rail fixedly connected to the inner cavity of the pulping tank and used to install the ball, and a spike assembly fixedly connected to the bottom of the connecting frame.

[0010] The inner bottom surface of the guide rail has several protrusions for repeatedly lifting the rolling ball.

[0011] The motor drives the shaft to rotate, and the sleeve and the connecting frame rotate synchronously. When the rolling ball moves along the guide rail, the convex on the bottom surface of the guide rail repeatedly lifts the rolling ball, forcing the connecting frame and the spike assembly to move up and down while rotating. When the spike assembly rotates and moves up and down in the pulp, it pierces the bubbles generated during stirring through physical piercing, avoiding bubble retention. The tension spring ensures that the rolling ball is always in contact with the guide rail, maintaining the continuity of the up-and-down movement and enhancing the stability of bubble removal.

[0012] The application actively destroys bubbles through the composite motion of the spike assembly, reduces the problem of uneven distribution of fibers, thereby improving the uniformity and strength of the paper. The bubble removal assembly and the stirring function are integrated in the same shaft, without the need for an additional power source or independent device, simplifying the structure, reducing the cost, and saving installation space. The convex of the guide rail cooperates with the spring to automatically adjust the motion amplitude of the spike assembly according to the stirring state, adapt to different viscosities of the pulp, and enhance the applicability. The stirring and bubble removal are completed synchronously, shortening the process flow time and improving the beating efficiency. In summary, the application innovatively combines traditional stirring and active bubble removal functions through mechanical linkage, specifically solves the problem of pulp bubbles, and has functionality and economy.

[0013] Further preferred technical solutions are that the spike assembly includes a hollow pipe, a vertical rod movably connected inside the hollow pipe and extending to the outside of the hollow pipe at the bottom end, a connecting plate fixedly connected to the bottom end of the vertical rod, a plurality of spike rods fixedly connected to the bottom end of the connecting plate, and a spring arranged between the inner wall of the hollow pipe and the inner end of the vertical rod.

[0014] Further preferred technical solutions are that the connecting frame is provided in two groups and symmetrically arranged along the sleeve.

[0015] Further preferred technical solutions are that the outside of the sleeve is fixedly connected with a plurality of stirring rods at equal intervals in the circumferential direction.

[0016] Further preferred technical solutions are that the bottom of the beating tank is in a funnel-shaped structure.

[0017] Further preferred technical solutions are that the outside of the shaft is symmetrically fixedly connected with a limiting strip, and the inner wall of the sleeve is provided with a limiting groove for slidingly connecting the limiting strip.

[0018] Further preferred technical solutions are that the two ends of the tension spring are fixedly connected with a protruding part on the shaft and the sleeve, respectively.

[0019] Further preferred technical solutions are that the top end of the vertical rod is fixedly connected with a limiting plate, and the limiting plate is fixedly connected with the spring.

[0020] Further preferred technical solutions are that the bottom end of the spike rod is in a conical structure.

[0021] Further preferred technical solutions are that the feeding pipe and the discharging pipe are respectively provided with valves.
