A cotton refining and beating device

Abstract

This application relates to a refined cotton pulping device, including a storage cylinder and a pulp storage cylinder sealed outside the storage cylinder. The bottom of the pulp storage cylinder is provided with a support base, and the upper end of the support base is provided with a hydraulic push rod. A piston disc is provided at the push rod of the hydraulic push rod, and the piston disc is sealed against the inner wall of the storage cylinder. In this refined cotton pulping device, as the piston disc moves upward, it pushes out the pulp that has undergone pulping treatment, allowing it to flow through carding needles to card and disperse the pulp fibers before being discharged into the pulp storage cylinder. Furthermore, during the rotation of the pulping roller and the pulping process, the crossbar rotates synchronously, and in conjunction with the output motor, the dispersing roller rotates. This allows the dispersing roller to rotate around the storage space of the storage cylinder and the pulp storage cylinder during its rotation, dispersing the pulp after pulping treatment, preventing pulp sedimentation and accumulation, and ensuring the pulping and mixing dispersion effects.

Description

Technical Field

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

[0002] Refined cotton is a basic raw material for the production of important chemical products such as cellulose acetate and carboxymethyl cellulose (CMC). During the production process, the refined cotton, after being cooked using an alkaline method, needs to be pulped to facilitate subsequent rinsing processes.

[0003] Chinese patent CN223226389U discloses a refined cotton pulping device, which uses a pulping roller to rapidly beat the pulp floating on the liquid surface. Although it achieves a good pulping effect, the pulp after pulping is still mixed with the original pulp and is not separated. Instead, it is repeatedly pulped, so the pulping efficiency needs to be improved. In addition, the pulp is prone to sedimentation after pulping, which cannot guarantee the mixing effect of the pulp and water after pulping, and is not conducive to subsequent rinsing operations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a refined cotton pulping device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A refined cotton pulping device includes a storage cylinder and a pulp storage cylinder sealed outside the storage cylinder. The bottom of the pulp storage cylinder is provided with a support base, the upper end of the support base is provided with a hydraulic push rod, the push rod of the hydraulic push rod is provided with a piston plate, the piston plate is sealed against the inner wall of the storage cylinder, and a plurality of carding needles are provided at equal intervals in a ring at the upper end of the storage cylinder.

[0007] The upper part of the storage cylinder is provided with a support frame, the upper part of the support frame is provided with an output motor one, the output shaft of the output motor one is provided with an output motor two, the output shaft of the output motor two is provided with a pulping roller, the pulping roller is located inside the storage cylinder, the output shaft of the output motor one is provided with a crossbar, the upper end of the crossbar is provided with an output motor three on both the left and right sides, the output shaft of the output motor three is provided with a dispersing roller, the dispersing roller is located between the storage cylinder and the storage cylinder.

[0008] Using the above technical solution, clean water and refined cotton pulp are stored in a storage cylinder. A piston disc is moved by a hydraulic pusher, causing the stored mixture to move upward. During the upward movement, the output motor 1 on the support frame drives the pulping roller on the output motor 2 to rotate on the surface of the mixture. At the same time, the output motor 2 drives the pulping roller to rotate, thus achieving pulping treatment of the pulp. As the piston disc moves upward and pushes the material, the pulp that has been pulped on the surface is pushed out and flows through the carding needles. After the pulp fibers are carded and dispersed, they are discharged into the storage cylinder, achieving pulp separation. During the rotation of the pulping roller and pulping, the crossbar rotates synchronously, and in conjunction with the output motor 3, the dispersing roller rotates. During its rotation, the dispersing roller rotates around the storage cylinder and the storage space of the storage cylinder to disperse the pulped pulp, preventing pulp sedimentation and accumulation, and ensuring the pulping and mixing dispersion effect of the pulp.

[0009] As a preferred technical solution of this utility model, the upper surface of the piston disc forms a downward inclined surface from the center to the outer ring wall.

[0010] By adopting the above technical solution, the inclined surface ensures that the slurry is discharged from the inclined surface when the piston disc moves to the top.

[0011] As a preferred embodiment of this utility model, the upper surface of the storage cylinder forms a downwardly sloping surface from the inner ring wall to the outer ring wall.

[0012] By adopting the above technical solution, the inclined surface is designed to prevent slurry from accumulating on the upper surface of the storage cylinder and being unable to be discharged.

[0013] As a preferred embodiment of this utility model, the lower surface of the slurry storage cylinder is connected to a slurry discharge pipe, and the outside of the slurry discharge pipe is connected to a switch valve.

[0014] Using the above technical solution, the stored slurry can be discharged through the slurry discharge pipe by simply opening the switch valve.

[0015] As a preferred embodiment of this utility model, the lower end of the crossbar is provided with an outer cover located outside the upper end of the combing needle.

[0016] The above technical solution, with its outer cover, prevents slurry from splashing out during pulping by the pulping roller.

[0017] As a preferred technical solution of this utility model, the output motor 2 is provided with a detachable mounting sleeve on its exterior, and the output motor 2 is connected to the output shaft of the output motor 1 through the mounting sleeve.

[0018] By adopting the above technical solution, the mounting sleeve ensures the installation and fixation effect, as well as the protection effect on the second output motor.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0020] During the rotation and pulping process of the pulping roller, the crossbar rotates synchronously, and the output motor drives the dispersing roller to rotate. As the dispersing roller rotates, it rotates around the storage space of the storage cylinder and the pulp storage cylinder to disperse the pulped pulp. Under the action of the piston plate moving upward, the pulped pulp is discharged to the storage cylinder through the carding needle, realizing pulp separation. This not only improves pulping efficiency, but also avoids pulp sedimentation and accumulation, ensuring the pulping effect and mixing and dispersion effect of the pulp. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1 to 3 The refined cotton pulping device in this embodiment mainly includes a storage cylinder 1, a pulp storage cylinder 5, a support base 2, a hydraulic push rod 3, a piston disc 4, a carding needle 6, a support frame 7, an output motor 1 8, an output motor 2 9, a pulping roller 10, an outer cover 11, a crossbar 12, an output motor 3 13, a dispersing roller 14, a pulp discharge pipe 15, and a switch valve 16.

[0028] The slurry storage cylinder 5 is sealed and fixed to the outside of the storage cylinder 1, forming a double-layer storage structure. A support base 2 is fixedly installed at the bottom of the slurry storage cylinder 5, which provides stable support for the entire device. A hydraulic push rod 3 is installed and fixed on the upper surface of the support base 2. A piston disc 4 is connected and fixed at the push rod of the hydraulic push rod 3. The piston disc 4 is tightly fitted with the inner wall of the storage cylinder 1 to achieve a seal and prevent slurry leakage.

[0029] Multiple carding needles 6 are fixed at equal intervals in a ring at the upper end of the storage cylinder 1. These needles are used to card and disperse the pulp fibers after beating, thereby achieving pulp separation. In this application, the number of carding needles 6 is not less than 100, and can be set according to the actual carding situation. A support frame 7 is fixedly installed on the upper surface of the outer side of the storage cylinder 5. The support frame 7 provides support for the motor and beating component above. An output motor 1 8 is installed and fixed on the upper surface of the support frame 7. An output motor 2 9 is installed at the output shaft of the output motor 1 8. A beating roller 10 is installed and fixed at the output shaft of the output motor 2 9. The beating roller 10 is located inside the storage cylinder 1 and is used to beate the pulp inside the storage cylinder 1.

[0030] A crossbar 12 is fixedly installed on the outside of the output shaft of the output motor 18. The left and right sides of the upper surface of the crossbar 12 are symmetrically installed and fixed with the output motor 3 13. A dispersing roller 14 is fixed at the output shaft of the output motor 3 13. The dispersing roller 14 is located between the storage cylinder 1 and the slurry storage cylinder 5 and is used to disperse the slurry discharged into the slurry storage cylinder 5 after slurrying to prevent sedimentation and accumulation.

[0031] The upper surface of the piston disc 4 forms a downward inclined surface from the center to the outer ring wall. This inclined surface is designed so that when the piston disc 4 moves to the top, the slurry can be smoothly discharged along the inclined surface, avoiding the accumulation of slurry on the piston disc 4. The piston disc 4 is fixed to the push rod of the hydraulic push rod 3 by threaded connection or other reliable connection method to ensure that it can move up and down stably under the action of the hydraulic push rod 3.

[0032] The upper surface of the storage cylinder 1 forms a downward sloping surface from the inner ring wall to the outer ring wall. The function of this sloping surface is to prevent the slurry from accumulating on the upper surface of the storage cylinder 1 and being unable to be discharged, so as to ensure that the slurry can flow smoothly through the carding needles 6 and be discharged into the storage cylinder 5. The storage cylinder 1 is generally made of corrosion-resistant and high-strength materials such as stainless steel to ensure its stability and durability during use.

[0033] Multiple combing needles 6 are evenly arranged in a ring at equal intervals at the top of the storage cylinder 1. The combing needles 6 are made of slender metal needles, and their length and diameter are designed according to actual needs. They can effectively comb and disperse the pulp fibers, making the pulp more uniform.

[0034] The support frame 7 is made of metal and has sufficient strength and stability. It is fixed to the upper part of the outside of the slurry storage cylinder 5 by bolts or other connection methods, providing a solid support for the output motor 8.

[0035] The output motor 29 is externally fixed with a mounting sleeve that can be detached by bolts. The output motor 29 is connected and fixed to the output shaft of the output motor 18 through the mounting sleeve. The mounting sleeve is generally made of metal or high-strength plastic material to ensure the installation and fixing effect and the protection effect of the output motor 29.

[0036] Output motor 8 drives output motor 9 to rotate, and output motor 9 drives pulping roller 10 to rotate, realizing the revolution and rotation of pulping roller 10 on the surface of the mixture, improving the pulping effect. Output motor 13 drives dispersing roller 14 to rotate, and at the same time, it rotates around the storage space of storage cylinder 1 and pulp storage cylinder 5 with the rotation of crossbar 12.

[0037] Both the pulping roller 10 and the dispersing roller 14 are made of metal with a certain degree of surface roughness to enhance the pulping and dispersing effect. The length and diameter of the pulping roller 10 are designed according to the inner diameter of the storage cylinder 1 to ensure full contact with the pulp for pulping. The length and diameter of the dispersing roller 14 are designed according to the distance and depth between the storage cylinder 1 and the pulp storage cylinder 5 to effectively disperse the pulp within this space.

[0038] Please see Figure 4 The lower end surface of the crossbar 12 is fixed with an outer cover 11 located outside the upper end of the combing needle 6. The outer cover 11 is made of transparent plastic or metal material and is a cylinder with an opening at the lower end, which can cover the upper part of the combing needle 6. The outer cover 11 is set to prevent the pulp from splashing out when the pulping roller 10 is pulping, and to keep the environment around the device clean.

[0039] The lower surface of the slurry storage cylinder 5 is connected to a slurry discharge pipe 15. The slurry discharge pipe 15 is made of metal or plastic pipe, and its diameter is designed according to the discharge flow rate of the slurry. The outside of the slurry discharge pipe 15 is connected to a switch valve 16. The switch valve 16 adopts common ball valves or gate valves, etc. The valve is opened and closed by manual or electric means to control the discharge of slurry.

[0040] This device can be controlled by an automatic control system, which can use a PLC (Programmable Logic Controller) or other types of controllers, to control the operation of each component through a preset program.

[0041] Usage steps,

[0042] Prepare the pulp: Add clean water and refined cotton pulp to storage cylinder 1 in a certain proportion.

[0043] Start pulping: Turn on output motor 8 and output motor 9. Output motor 8 drives the pulping roller 10 on output motor 9 to rotate on the surface of the pulp. At the same time, output motor 9 drives the pulping roller 10 to rotate on its own, thus pulping the pulp.

[0044] Promoting the pulp: Start the hydraulic push rod 3 to push the piston disc 4 upward, causing the stored pulp to move upward. As the piston disc 4 moves upward, the output motor 8 on the support frame 7 drives the pulping roller 10 on the output motor 9 to rotate on the surface of the pulp. At the same time, the output motor 9 drives the pulping roller 10 to rotate, achieving full pulping treatment of the pulp. The pulp that has been pulped is pushed out and flows through the carding needle 6. The carding needle 6 card and disperses the pulp fibers, realizing pulp separation.

[0045] Dispersing the slurry: During the rotation and slurrying process of the slurry roller 10, the crossbar 12 is driven to rotate synchronously. At the same time, the output motor 3 13 is turned on, driving the dispersing roller 14 to rotate. During its rotation, the dispersing roller 14 rotates around the storage space of the storage cylinder 1 and the slurry storage cylinder 5 to disperse the slurry after slurrying and prevent the slurry from settling and accumulating.

[0046] Discharging slurry: After the pulping and dispersing process is completed, open the switch valve 16 to discharge the stored slurry through the slurry discharge pipe 15.

[0047] In summary, this refined cotton pulping device, through its reasonable structural design, achieves thorough pulping of refined cotton pulp, fiber combing and dispersion, and prevention of sedimentation and accumulation, thus possessing high practicality and promotional value.

[0048] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and the existing publicly available power connection technologies are not described in detail in the text.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
