Description

Technical Field

[0001] This utility model relates to the field of papermaking processing technology, specifically to a straw papermaking pulping device. Background Technology

[0002] In straw papermaking, pulping is a crucial step that determines pulp quality. Traditional pulping devices have fixed grinding gaps, which cannot be adjusted according to the hardness and moisture content of the straw, resulting in unstable pulping efficiency. Furthermore, the filter components are easily clogged by fibers, requiring frequent shutdowns for cleaning, which affects production continuity. At the same time, the equipment is cumbersome to disassemble and assemble, and internal maintenance and component replacement are time-consuming and labor-intensive. With the increasing demand for straw resource utilization, there is an urgent need for a high-efficiency pulping device that integrates shearing, grinding, and anti-clogging functions. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a straw papermaking pulping device, which solves the existing problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a straw papermaking pulping device, comprising a housing, a feed inlet at the top of the housing, a detachable feed hopper at the bottom, a discharge pipe at the bottom of the feed hopper, a conical filter cylinder fixedly installed inside the discharge pipe, a sleeve rotatably installed inside the housing, a rotating rod that can slide up and down axially inside the sleeve, the lower end of the rotating rod extending into the conical filter cylinder and equipped with a cleaning component, a fixed blade fixedly installed in the upper part of the housing, and a fixed grinding roller fixedly installed in the lower part of the housing, a moving blade fixedly installed on the outer wall of the sleeve and interleaved with the fixed blade, a moving grinding roller cooperating with the fixed grinding roller fixedly installed on the outer wall of the rotating rod, forming a grinding chamber between the moving grinding roller and the fixed grinding roller, an adjusting rod penetrating the sleeve installed at the upper end of the rotating rod, and a driving component installed on the upper wall of the housing.

[0005] Preferably, the drive assembly includes a motor and an electric actuator fixedly mounted on the upper wall of the housing. An adjustment plate is installed on the telescopic end of the electric actuator. The upper end of the adjustment rod is rotatably connected to the lower wall of the adjustment plate. A gear is installed on the drive end of the motor. The upper end of the sleeve penetrates the upper wall of the housing and is equipped with a gear ring that meshes with the gear.

[0006] Preferably, the inner wall of the sleeve is provided with a pair of first guide grooves, and the upper end of the rotating rod is provided with a pair of first guide blocks that are slidably connected to the first guide grooves.

[0008] Preferably, a pair of second guide grooves are provided on the inner walls of both sides of the mounting groove, and a pair of second guide blocks that are slidably connected to the second guide grooves are fixed on both sides of the connecting column.

[0009] Preferably, the bottom of the housing and the outer edge of the top of the hopper are provided with matching folded edges, and the upper and lower folded edges are connected by bolts and nuts.

[0010] Beneficial effects

[0011] This utility model provides a straw pulping device for papermaking, which has the following beneficial effects:

[0012] The moving and fixed blades alternately shear the pre-treated straw, breaking it into small pieces before it enters the grinding chamber of the moving and fixed grinding rollers for fine grinding, forming a two-stage processing mode of "shearing + grinding", which improves fiber uniformity and solves the problem of uneven fiber quality caused by a single processing method.

[0013] The grinding gap between the moving and stationary grinding rollers is changed by adjusting the rod to drive the rotating rod to slide up and down. This can be flexibly adjusted according to the dryness and hardness of the straw, ensuring that raw materials in different states can be efficiently ground and enhancing the versatility of the equipment.

[0014] The cleaning component at the lower end of the rotating rod rotates with the rotating rod, and the cleaning brush continuously cleans the inner wall of the conical filter cartridge to prevent fibers from clogging the filter holes; the spring buffer design makes the cleaning brush fit tightly against the filter cartridge, improving the cleaning effect and reducing the number of times the machine needs to be stopped for cleaning.

[0015] The hopper is detachably connected to the flange and bolts, which facilitates quick disassembly and cleaning of residual slurry and also makes it easy to clean the conical filter cartridge. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-2 This utility model provides a technical solution: a straw papermaking pulping device, including a housing 1, a feed inlet 2 at the top of the housing 1, a detachable feed hopper 3 at the bottom, a discharge pipe 4 at the bottom of the feed hopper 3, a conical filter cylinder 5 fixedly installed inside the discharge pipe 4, a sleeve 6 rotatably installed inside the housing 1, a rotating rod 7 that can slide up and down axially inside the sleeve 6, the lower end of the rotating rod 7 extending into the conical filter cylinder 5 and equipped with a cleaning component, a fixed blade 8 fixedly installed in the upper part of the housing 1, and a fixed grinding roller 9 fixedly installed in the lower part of the housing 1, a moving blade 10 fixedly installed on the outer wall of the sleeve 6 and intersecting with the fixed blade 8, a moving grinding roller 11 fixedly installed on the outer wall of the rotating rod 7 and cooperating with the fixed grinding roller 9, forming a grinding chamber between the moving grinding roller 11 and the fixed grinding roller 9, an adjusting rod 12 penetrating the sleeve 6 installed at the upper end of the rotating rod 7, and a driving component provided on the upper wall of the housing 1.

[0021] By adopting the above technical solution, the material is fed into the feed port 2, the motor 13 drives the sleeve 6 to drive the moving blade 10 to rotate, and cooperates with the fixed blade 8 to cut the material. The cut material enters the lower part, and the rotating rod 7 drives the moving grinding roller 11 to rotate relative to the fixed grinding roller 9 to grind into slurry. The slurry is filtered through the conical filter cylinder 5, and impurities are retained. The cleaning component at the lower end of the rotating rod 7 cleans the filter cylinder at the same time. The adjusting rod 12 can adjust the position of the rotating rod 7 and change the grinding gap.

[0022] In this embodiment, the driving assembly includes a motor 13 and an electric push rod 14 fixedly mounted on the upper wall of the housing 1. An adjustment plate 15 is installed on the telescopic end of the electric push rod 14. The upper end of the adjustment rod 12 is rotatably connected to the lower wall of the adjustment plate 15. A gear 16 is installed on the driving end of the motor 13. The upper end of the sleeve 6 penetrates the upper wall of the housing 1 and is equipped with a gear ring 17 that meshes with the gear 16.

[0023] By adopting the above technical solution, the motor 13 is started, and the gear 16 drives the gear ring 17 to rotate the sleeve 6, so that the moving blade 10 cuts and the moving grinding roller 11 grinds. When the grinding gap needs to be adjusted, the electric push rod 14 pushes the adjusting plate 15 to drive the adjusting rod 12 and the rotating rod 7 to slide up and down, changing the distance between the moving grinding roller 11 and the fixed grinding roller 9. The adjusting plate 15 and the adjusting rod 12 are rotatably connected to ensure that the rotating rod 7 can move axially while rotating synchronously with the sleeve 6.

[0024] In this embodiment, the inner wall of the sleeve 6 is provided with a pair of first guide grooves 18, and the upper ends of the rotating rod 7 are provided with a pair of first guide blocks 19 that are slidably connected to the first guide grooves 18.

[0025] By adopting the above technical solution, when the rotating rod 7 slides along the axial direction of the sleeve 6, the first guide block 19 moves synchronously along the first guide groove 18, restricting the circumferential rotation of the rotating rod 7 and ensuring that the rotating rod 7 rotates synchronously with the sleeve 6.

[0026] In this embodiment, the cleaning component is further configured such that the cleaning component includes a mounting groove 20 located at the lower end of the rotating rod 7, a connecting post 21 is slidably disposed in the mounting groove 20, the upper end of the connecting post 21 is connected to the top of the mounting groove 20 by a spring 22, and a pair of cleaning brushes 23 are fixedly installed at the lower end.

[0027] By adopting the above technical solution, when the rotating rod 7 rotates, the connecting column 21 drives the cleaning brush 23 to rotate synchronously, cleaning the deposits on the inner wall of the conical filter cylinder 5, and the spring 22 pushes the connecting column 21 to make the cleaning brush 23 always closely fit the filter cylinder.

[0028] In this embodiment, the inner walls on both sides of the mounting groove 20 are provided with a pair of second guide grooves 24, and a pair of second guide blocks 25 that are slidably connected to the second guide grooves 24 are fixedly provided on both sides of the connecting column 21.

[0029] In this embodiment, the bottom of the housing 1 and the top outer edge of the hopper 3 are provided with matching folded edges, and the upper and lower folded edges are connected by bolts and nuts.

[0030] By adopting the above technical solution, when it is necessary to clean the hopper 3 or replace the conical filter cartridge 5, the bolts and nuts of the folded edge connection can be unscrewed to separate the hopper 3 from the shell 1. After cleaning or replacement, the folded edge is aligned and the bolts are tightened again to achieve quick assembly.

[0031] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0032] Example: Based on the material characteristics, the position of the rotating rod 7 is adjusted by the electric actuator 14 to set the grinding gap between the moving grinding roller 11 and the fixed grinding roller 9. The material is continuously fed in from the feed inlet 2, the motor 13 is started, the sleeve 6 drives the moving blade 10 to rotate, and the rotating rod 7 drives the moving grinding roller 11 to rotate. The moving blade 10 and the fixed blade 8 cut the straw, and after crushing, it enters the grinding chamber. The material forms pulp under the squeezing and grinding action of the moving grinding roller 11 and the fixed grinding roller 9. The pulp is filtered through the conical filter cylinder 5 and discharged through the discharge pipe 4. Coarse fiber impurities are intercepted. After the batch pulping is completed, the motor 13 is turned off, the folded bolt is unscrewed, the feed hopper 3 is removed, and the residual impurities in the conical filter cylinder 5 are cleaned. It is convenient to use.
