[0030] In the related art, the principle is to drive the scraper to rotate on the filter screen by the motor driving the bevel gear meshing, which can avoid filter screen blockage. However, in the existing device, the bevel gear is arranged inside the discharge pipe, which will be attached to the bevel gear when the paper pulp is discharged, affecting the meshing between the gears, so it is not practical in actual use

[0031] To address some of the problems in the related technologies, this application provides a pulping device for paper production. When pulping is required for paper production, the pulp and water inside the pulping tank 11 are mixed evenly, and the pulp is stirred more finely. After the mixing is completed, the pulp is discharged through the discharge pipe 12. During discharge, the motor 21 is connected to an external power source. The pulp is then filtered through the filter screen 13 via the discharge pipe 12. At this time, the motor 21 drives the pressing block 22. During rotation, in conjunction with the spring 28, the pressing plate 27 can be dragged up and down inside the housing 23. At the same time, the frame 25 at the bottom of the upright 24 also moves up and down, driving the insertion rod 26 to clear the holes in the filter screen 13 to prevent blockage during rotation.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] This application provides a pulping device for paper production, including: a pulping tank 11 with a feed pipe 12 at its bottom; a filter screen 13 disposed inside the feed pipe 12; a cleaning assembly 2 disposed inside the feed pipe 12, the cleaning assembly 2 including: a motor 21 disposed on the outer wall of the feed pipe 12, with its output shaft inserted into the feed pipe 12; a pressing block 22 disposed on the output shaft of the motor 21; a housing 23 with its bottom end penetrating through the filter screen 13 and fixedly connected to the filter screen 13; a vertical rod 24 with its bottom end penetrating through the housing 23; a frame 25 disposed at the bottom end of the vertical rod 24; an insert rod 26 disposed at the top of the frame 25; a pressure plate 27 fixedly sleeved on the outer wall of the vertical rod 24; a spring 28 with both ends connected to the inner wall of the housing 23 and the pressure plate 27; and an installation assembly 3 disposed on the feed pipe 12 for fixing the position of the filter screen 13 inside the feed pipe 12.

[0034] Specifically, the working principle of a pulping tank mainly includes the operation of the mixing system, the design of the tank, and the various stages of the workflow.

[0035] stirring system

[0036] The mixing system of a pulping tank consists of a motor, a reducer, a coupling, and an agitator. The motor provides power, which is reduced in speed and increased in torque by the reducer, ultimately driving the agitator to rotate. The type and design of the agitator directly affect the mixing effect; for example, a three-bladed swept blade is suitable for medium to low viscosity materials, while an anchor-type blade is often used for high viscosity systems.

[0037] Waterproof rings are installed at the connection points between the housing 23 and the upright 24 to prevent water from entering the housing 23.

[0038] When the paper production needs to be beaten, the pulp and water inside the beating tank 11 are mixed evenly, and the pulp is stirred more finely. After the process is completed, the pulp is discharged through the discharge pipe 12. When discharging, the motor 21 is connected to an external power source, and then the pulp is filtered through the filter screen 13. At this time, the motor 21 drives the extrusion block 22, which, in cooperation with the spring 28, can drag the pressing plate 27 to move up and down inside the shell 23. At the same time, the frame 25 at the bottom end of the vertical rod 24 also moves up and down, driving the plug rod 26 to dredge the holes of the filter screen 13 to avoid blockage during rotation.

[0039] Further, the spring 28 is sleeved on the outside of the vertical rod 24.

[0040] When in use, the design of the sleeve can limit the spring 28 from bending when it is compressed, thereby better protecting the spring 28.

[0041] Further, the cleaning assembly 2 further comprises: a top plate 29 arranged on the top of the vertical rod 24.

[0042] When in use, the design of the top plate 29 can prevent the top end of the vertical rod 24 from retracting completely into the shell 23, and can increase the contact between the top end of the vertical rod 24 and the extrusion block 22.

[0043] Further, the installation assembly 3 comprises: a groove 31 opened in the inner side wall of the discharge pipe 12; a spring 32 arranged inside the groove 31; a U-shaped plate 33 inserted into the inside of the groove 31 and connected with the spring 32; and a pull rod 34 inserted through the outer side wall of the discharge pipe 12 and connected with the U-shaped plate 33 through the spring 32.

[0044] When the filter screen 13 needs to be disassembled, the pull rod 34 is pulled to retract the U-shaped plate 33 into the groove 31, and the inside of the U-shaped plate 33 is separated from the filter screen 13, so that the filter screen 13 can be disassembled from the inside of the discharge pipe 12.

[0045] Further, the installation assembly 3 further comprises: a vertical plate 35 arranged on one end of the pull rod 34; and an inclined ring 36 sleeved on the outer side wall of the discharge pipe 12.

[0046] When the U-shaped plate 33 is controlled to retract, the inclined ring 36 can be slid upward to press the vertical plate 35, thereby driving the vertical plate 35 to move, and the vertical plate 35 pulls the pull rod 34 to move.

[0047] Further, the installation assembly 3 further comprises: a convex rod 37 arranged on the outer side wall of the inclined ring 36

[0048] The design of the convex rod 37 is convenient to grip and better controls the upward movement of the inclined ring 36.

[0049] Further, the installation assembly 3 further comprises: an arc-shaped block 38 arranged at the bottom end of the vertical plate 35.

[0050] The design of the arc-shaped block 38 can reduce the scratch between the components when contacting the inclined ring 36.

[0051] Further, the installation assembly 3 further comprises: a blocking ring 39 fixedly arranged at the outer wall of the bottom end of the discharging pipe 12.

[0052] The design of the blocking ring 39 can avoid the disengagement of the inclined ring 36 from the discharging pipe 12.

[0053] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "an example", "a specific example", "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in the present specification.
