Description

Technical Field

[0001] This utility model relates to the field of paper production and processing technology, and in particular to a high-shear pulping kettle. Background Technology

[0002] Paper is indispensable in daily life. The paper we use is made from plant fibers as the main raw material through complex processes such as pulping, bleaching, beating, papermaking, and post-processing. In the paper production process, the beating step is to shear and fusiform the fibers, making them softer and improving the uniformity and quality of the paper. The beating kettle is a key piece of equipment in this stage of the beating process. The high shear force of the beating kettle allows the fibers to be processed to the ideal state more quickly, reducing processing time, further refining the fibers and increasing the bonding force between the fibers, thereby improving the strength and uniformity of the paper. This device is mainly used in the pulping workshop of paper mills and large-scale paper production workshops.

[0003] In existing technologies, pulping kettles use a high-speed motor to drive a connecting shaft that rotates the blades. The fiber suspension is forced through a very small space, generating high-intensity shear force. However, during the pulping process, fibers may form clumps, or impurities and additives in the pulp may aggregate into clumps, and some fibers may be too long and not sufficiently refined. These can accumulate at the discharge port, causing blockages. Cleaning blocked discharge ports requires a significant amount of time and manpower. Workers need to stop the machine, disassemble relevant components, and use tools to unclog and clean the outlet. This not only increases labor intensity but also leads to recurring blockages due to incomplete cleaning. Therefore, a high-shear pulping kettle is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-shear pulping kettle, which aims to improve the problem of difficult-to-clean discharge port blockage in the prior art, which consumes time and manpower and thus affects the overall work quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-shear pulping kettle, comprising a kettle body, a connecting rod rotatably connected inside the kettle body, a driving assembly fixedly connected to one end of the connecting rod, a fixing ring fixedly connected to the outer wall of the connecting rod, a blade fixedly connected to the outer wall of the fixing ring, a scraper buffer assembly provided on the outer wall of the fixing ring, a discharge pipe fixedly connected to the bottom of the kettle body, a valve rotatably connected to the inner wall of the discharge pipe, a filter box fixedly connected to the outer wall of the discharge pipe, and a filter assembly provided inside the filter box;

[0006] The filter assembly includes a coarse screen, a connecting block fixedly connected to the top of the coarse screen, a latch switch on the side wall of the connecting block, a connecting shaft rotatably connected to the inner wall of the latch switch, both ends of the connecting shaft fixedly connected to the inside of the filter box, a second spring on the side wall of the latch switch, a first spring on the inner wall of the filter box, a connecting block fixedly connected to one end of the first spring, a first connecting block slidably connected to the bottom of the connecting block on its outer wall, and a fine screen fixedly connected to the bottom of the connecting block.

[0007] Furthermore, the buffer scraper assembly includes a buffer disc, the top of which is fixedly connected to the bottom of a fixed ring. A connecting rod two is fixedly connected to the outer wall of the fixed ring. A connecting block two is slidably connected to the outer wall of the connecting rod two. A spring three is provided on the inner wall of the connecting block two. One end of the spring three is fixedly connected to the top of the connecting rod two. A connecting frame is fixedly connected to the outer wall of the connecting block two. A scraper strip is fixedly connected inside the connecting frame.

[0008] Furthermore, the outer wall of the connecting rod is disposed on the inner wall of the vessel body, and a feed pipe is fixedly connected to the upper surface of the vessel body.

[0009] Furthermore, a drive assembly is fixedly connected to the upper surface of the vessel body. The drive assembly includes a motor, a connector is fixedly connected to the outer wall of the motor, and the output end of the motor is fixedly connected to one end of the connecting rod.

[0010] Furthermore, one end of the connecting rod is disposed at the top of the scraper, and the bottom of the scraper is disposed on the upper surface of the discharge pipe.

[0011] Furthermore, the lower surface of the discharge pipe is disposed on the top of the second support frame, and the top of the second support frame is fixedly connected to the bottom of the filter box.

[0013] Furthermore, a support frame is fixedly connected to the outer wall of the vessel body, and the support frame is used to assist in the installation and fixation of the vessel body.

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

[0015] 1. In this utility model, by lifting the buckle switch upwards to disengage it from the bottom groove of the connecting block, the connecting block connected by the spring is pushed outwards, which in turn causes the coarse screen fixedly connected to the connecting block to pop outwards. This achieves the effect of quickly replacing the filter screen and can more effectively intercept larger particles, insufficiently refined long fibers and other impurities, avoiding clogging problems caused by these substances. It is easy to disassemble and clean, which can significantly improve the performance of the equipment, simplify daily maintenance work, and improve the quality of the final product.

[0016] 2. In this utility model, the connecting rod rotates, causing the connecting scraper to rotate tightly against the inner wall of the reactor. The rotation of the scraper can clean up the pulp that splashes onto the inner wall of the reactor when the blades are rotating at high speed. At the same time, a scraper is also provided at the bottom to clean up the pulp residue at the bottom while the connecting rod rotates. The cleaning scraper can continuously scrape the inner wall of the reactor as the stirring shaft rotates or other driving devices drive it, so as to scrape off the pulp adhering to the wall surface in time, improve the uniformity and consistency of pulping, and help produce pulp with stable quality.

[0023] 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.

[0024] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model is provided: a high-shear pulping kettle, including a kettle body 1, a connecting rod 8 rotatably connected inside the kettle body 1, a driving assembly fixedly connected to one end of the connecting rod 8, the driving assembly being used to provide power to drive the connecting rod 8, a fixing ring 12 fixedly connected to the outer wall of the connecting rod 8, a blade 13 fixedly connected to the outer wall of the fixing ring 12, a scraper buffer assembly provided on the outer wall of the fixing ring 12, a discharge pipe 5 fixedly connected to the bottom of the kettle body 1, a valve 26 rotatably connected to the inner wall of the discharge pipe 5, the valve 26 being used to close the bottom space of the kettle body 1 during pulping, a filter box 6 fixedly connected to the outer wall of the discharge pipe 5, and a filter assembly being provided inside the filter box 6;

[0025] The filter assembly includes a coarse screen 16, a connecting block 14 fixedly connected to the top of the coarse screen 16, a latch switch 21 provided on the side wall of the connecting block 14, a connecting shaft 20 rotatably connected to the inner wall of the latch switch 21, both ends of the connecting shaft 20 fixedly connected to the inside of the filter box 6, a second spring 22 provided on the side wall of the latch switch 21, a first spring 18 provided on the inner wall of the filter box 6, a first connecting block 19 fixedly connected to one end of the first spring 18, a first connecting block 19 slidably connected to the bottom of the connecting block 14 on the outer wall, and a fine screen 17 fixedly connected to the bottom of the connecting block 14.

[0026] Specifically, after the pulping process is completed, the paper pulp is extracted through the discharge pipe 5 by opening the rotary valve 26. At this time, the latch switch 21 is activated. After the latch switch 21 is subjected to force, the other end of the latch switch 21 squeezes the second spring 22. At the same time, the other end of the latch switch 21 disengages from the bottom groove of the connecting block 14. After disengagement, the connecting block 14 loses its limiting function and is squeezed outward by the connecting block 19 connected to one end of the spring 18. This causes the coarse screen fixedly connected to the connecting block 14 to pop outward, achieving the effect of quickly replacing the screen.

[0027] Reference Figure 4 The buffer scraper assembly includes a buffer disc 9, the top of which is fixedly connected to the bottom of a fixed ring 12. The buffer disc 9 is used to buffer the force of the papermaking raw material directly impacting the blade 13 during feeding. A connecting rod 15 is fixedly connected to the outer wall of the fixed ring 12. A connecting block 24 is slidably connected to the outer wall of the connecting rod 15. A spring 23 is provided on the inner wall of the connecting block 24. One end of the spring 23 is fixedly connected to the top of the connecting rod 15. A connecting frame 10 is fixedly connected to the outer wall of the connecting block 24. A scraper 11 is fixedly connected inside the connecting frame 10.

[0028] Specifically, the motor 2 drives the connecting rod 8 to rotate, which in turn drives the connecting frame 10 connected to the top of the connecting rod 15 to rotate. At the same time, the connecting frame 10 is squeezed by the spring 23 inside the connecting block 24, which drives the connected scraper 11 to rotate tightly against the inner wall of the reactor body 1. The rotation of the scraper 11 can clean the pulp splashed onto the inner wall of the reactor body 1 by the blade 13 during high-speed rotation and pulping, achieving a cleaning effect. At the same time, a scraper 11 is also provided at the bottom, which drives the scraper 11 to rotate while the connecting rod 8 rotates, cleaning the paper pulp residue at the bottom.

[0029] Working principle: First, the paper pulp is injected into the reactor body 1 through the feed pipe 3. After contacting the upper surface of the buffer plate 9, the paper pulp slides into the interior of the reactor body 1. The buffer plate 9 buffers the direct contact between the paper pulp and the blade 13. Then, the drive motor 2 outputs to drive the connecting rod 8 to rotate. At the same time, the blade 13, which is fixedly connected to the fixing ring on the connecting rod 8, rotates and begins to perform high-speed shearing of the paper pulp. While the connecting rod 8 is rotating, it also drives the connecting frame 10 connected to the top of the connecting rod 15 to rotate. At the same time, the connecting frame 10 is squeezed by the spring 23 inside the connecting block 24, which causes the connected scraper 11 to rotate tightly against the inner wall of the reactor body 1. The rotation of the scraper 11 can clean the blade 1. 3. During high-speed rotating pulping, the paper pulp splashes onto the inner wall of the reactor body 1. At the same time, a scraper 11 is also provided at the bottom. As the connecting rod 8 rotates, it drives the scraper 11 to rotate and clean the paper pulp residue at the bottom. After the pulping process is completed, the rotary valve 26 draws out the paper pulp through the discharge pipe 5. At this time, the latch switch 21 is activated. After the latch switch 21 is subjected to force, the other end of the latch switch 21 squeezes the spring 22. At the same time, the other end of the latch switch 21 disengages from the bottom groove of the connecting block 14. After disengagement, the connecting block 14 loses its limiting function and is squeezed outward by the connecting block 19 connected to one end of the spring 18. Then, the coarse screen 16 fixedly connected to the connecting block 14 is ejected outward to achieve the effect of quickly replacing the screen.

[0030] 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.
