Description

Technical Field

[0001] This utility model relates to the field of refined cotton production technology, specifically to refined cotton alkali removal equipment. Background Technology

[0002] Refined cotton is a white, flocculent material made from cotton linters through processes such as alkaline cooking, bleaching, milling to remove water, and air-drying. It is a fundamental raw material for the production of important chemical products such as nitrocellulose, cellulose acetate, and carboxymethyl cellulose (CMC). After alkaline cooking, refined cotton needs to be cleaned to remove the alkaline solution, which facilitates subsequent bleaching.

[0003] Chinese patent CN223226387U discloses a device for cleaning alkali in refined cotton, which cleans alkali through vibration spraying and rolling. However, on the one hand, since the water content in refined cotton is already relatively saturated, water cannot penetrate into the refined cotton again. At the same time, the vibration method cannot make the refined cotton loose and fluffy. On the other hand, it cannot effectively separate and clean impurities in the refined cotton during the cleaning process. Therefore, we propose a device for cleaning alkali in refined cotton to solve this technical defect. Utility Model Content

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

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

[0006] A cotton alkali removal device includes an alkali removal box, a switch cover hinged to the upper end of the alkali removal box, and a drain pipe connected to the lower end of the alkali removal box. A drive motor is provided at the bottom of the alkali removal box with the same center. A grid spin dryer is provided at the output end of the drive motor and is located inside the alkali removal box.

[0007] A support frame is provided on the left side of the alkali removal box. A hydraulic push rod is provided at the upper left end of the support frame. A loading plate is provided at the push rod of the hydraulic push rod. A hydraulic push rod is provided at the upper end of the loading plate. An output motor is provided at the push rod of the hydraulic push rod. A guide frame is provided at the push rod of the output motor. A pair of movable seats slide inside the guide frame. A drive assembly is provided on the guide frame to drive the movable seats to move in opposite directions.

[0008] The upper end of the movable base is equipped with a rotary motor, the output end of the rotary motor is equipped with a dispersing roller, the outside of the dispersing roller is connected to multiple evenly distributed dispersing hollow cylinders, and the guide frame is equipped with an air-filling component that fills the dispersing roller with airflow.

[0009] Using the above technical solution, when in use, by opening the switch cover on the alkali removal box, putting the refined cotton into the grid spin dryer, closing the switch cover, and driving the grid spin dryer to rotate by the drive motor, the alkali solution absorbed by the refined cotton in the grid spin dryer can be spun out and discharged through the drain pipe.

[0010] After the alkali solution is discharged from the refined cotton, clean water is drained into the alkali cleaning tank by opening the switch cover. Simultaneously, the hydraulic push rod two on the loading plate drives the output motor, guide frame, moving seat, rotary motor, dispersing roller, and dispersing hollow cylinder to move up and down synchronously. This moves the dispersing roller and dispersing hollow cylinder to the top of the alkali cleaning tank. Furthermore, hydraulic push rod one pushes the loading plate, hydraulic push rod two, output motor, guide frame, moving seat, rotary motor, dispersing roller, and dispersing hollow cylinder to move horizontally, bringing them to the top of the grid drying cylinder. The cotton is then moved into the grid spin dryer, where the dispersing roller and the dispersing hollow cylinder are submerged in water. In addition, the output motor drives the guide frame, the dispersing roller, and the dispersing hollow cylinder to rotate inside the grid spin dryer. At the same time, the rotary motor drives the dispersing hollow cylinder to rotate on its own axis. During the rotation and self-rotation, the drive assembly drives the dispersing hollow cylinder to move towards each other, so that the combination of the dispersing roller and the dispersing hollow cylinder can fully disperse the refined cotton in the water, ensuring that the water is fully absorbed by the refined cotton and promoting the discharge of impurities in the refined cotton during the dispersing process.

[0011] The air-filling component inflates the hollow dispersing cylinder, causing the gas to escape and form bubbles in the water. These bubbles rise and adhere to impurities, promoting their removal. After water absorption is complete, the wastewater is discharged through the drain pipe, allowing impurities and lint to be discharged simultaneously. After discharge, the switch cover is opened, causing the dispersing roller and hollow dispersing cylinder to move upwards and laterally to the side of the alkali-removing box to reset. The switch cover is then closed, and the refined cotton is spun dry with the grid drying cylinder. The drain pipe is then opened to remove water, thus significantly improving the water absorption and alkali removal effect of the refined cotton and achieving the removal of impurities from the refined cotton.

[0012] As a preferred technical solution of this utility model, the upper outer side of the alkali removal tank is connected to a water inlet pipe, which is connected to a faucet through a pipe, and a switch control valve is connected to the outside of the water inlet pipe.

[0013] Using the above technical solution, the water inlet connector pipe is connected to the faucet through a pipeline. By opening the faucet and switching the control valve, water can be discharged into the alkali removal tank.

[0014] As a preferred embodiment of this utility model, a pair of guide rods are provided on the left side of the loading plate, and the guide rods pass through to the left side of the support frame.

[0015] By adopting the above technical solution, during the process of the hydraulic push rod pushing the loading plate to move, the guide rod is driven to move on the support frame, thereby improving the stability of the loading plate movement.

[0016] As a preferred embodiment of this utility model, the output shaft of the output motor is connected to the upper middle part of the guide frame, and the movable seat is symmetrically distributed front and back based on the middle part of the guide frame;

[0017] The drive assembly includes a servo motor located at the front of the guide frame. The output end of the servo motor is provided with a bidirectional threaded rod, which passes through the movable seat. The other end of the movable seat is provided with a movable seat, which is connected to the inner side of the guide frame.

[0018] The outer side of the bidirectional threaded rod is provided with a forward thread groove and a reverse thread groove on the front and rear sides of the middle part of the guide frame, respectively. The forward thread groove and the reverse thread groove have opposite thread directions, and the forward thread groove and the reverse thread groove are respectively threaded to the two moving seats.

[0019] Using the above technical solution, the servo motor drives the bidirectional threaded rod to rotate on the movable seat. By utilizing the threaded connection between the forward and reverse threaded grooves on the bidirectional threaded rod and the movable seat, as well as the linear limiting sliding of the guide frame on the movable seat, the forward and reverse rotation of the bidirectional threaded rod can drive the movable seat to move in opposite directions within the guide frame, thereby driving the dispersing roller and the dispersing hollow cylinder to move synchronously in opposite directions.

[0020] As a preferred technical solution of this utility model, the inflation assembly includes an annular seat rotatably connected to the outside of the dispersing roller and a vortex blower disposed on the surface of the guide frame. An air pipe is connected to the exhaust port of the vortex blower, and a flexible hose is connected to the other end of the air pipe. The flexible hose is connected between the annular seats.

[0021] As a preferred embodiment of this utility model, the outer side of the dispersing roller is provided with a plurality of annularly distributed air holes, and the outer side of the dispersing roller is provided with an annular groove communicating with the air holes, the annular groove being used for the sealing rotation of the annular seat.

[0022] By adopting the above technical solution, during the rotation of the dispersing roller, the rotation of the annular groove and the annular seat ensures that the annular seat does not rotate synchronously during the rotation of the dispersing roller. During the process of the vortex blower working and discharging the airflow, the airflow is discharged from the dispersing hollow cylinder by utilizing the interconnection between the vortex blower, air pipe, hose, annular seat, air hole, dispersing roller and dispersing hollow cylinder.

[0023] As a preferred technical solution of this utility model, it also includes a water storage base, and a filter screen is installed in the partition of the water storage base. The filter screen is located above the opening at the other end of the sewage pipe.

[0024] Using the above technical solution, sewage discharged from the drain pipe flows into the filter screen on the water storage base, so that the filter screen can filter and isolate impurities and lint in the sewage, which is convenient for the collection and reuse of lint, and the alkaline sewage is stored in the water storage base.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] By moving the dispersing roller down into the grid drying cylinder, the dispersing roller is driven to rotate and the dispersing hollow cylinder rotates on its own. During the rotation and self-rotation, the dispersing hollow cylinders move towards each other, which fully disperses the refined cotton in the water, ensuring that the water is fully absorbed by the refined cotton, improving the water absorption and alkali removal effect of the refined cotton. In the process of dispersing, it can also promote the discharge of impurities in the refined cotton.

[0027] By inflating the hollow cylinder with an air-filling component, the air bubbles rise and adhere to impurities, promoting their discharge and thus cleaning impurities from refined cotton. Attached Figure Description

[0041] Hydraulic push rod 29 is fixed to the upper surface of loading plate 8. A connecting seat is fixed to the push rod. The connecting seat is used to install and fix the output motor 10. Hydraulic push rod 29 is used to drive the output motor 10, guide frame 12, moving seat 13, rotary motor 16, dispersing roller 17 and dispersing hollow cylinder 18 to move up and down synchronously.

[0042] The output motor 10 is a geared motor, and its output shaft is connected and fixed to the middle of the upper surface of the guide frame 12. The output motor 10 is used to drive the guide frame 12, the dispersing roller 17 and the dispersing hollow cylinder 18 to rotate inside the grid drying cylinder 4.

[0043] The guide frame 12 is a frame-like structure made of stainless steel. A pair of movable seats 13 slide inside the guide frame 12, and the movable seats 13 are symmetrically distributed back and forth based on the middle of the guide frame 12.

[0044] The guide frame 12 is equipped with a drive assembly that drives the moving seat 13 to move in opposite directions.

[0045] The drive assembly includes a servo motor 14 fixed to the front surface of the guide frame 12. A bidirectional threaded rod 15 is fixed to the output end of the servo motor 14. The bidirectional threaded rod 15 passes through the movable seat 13. The other end of the movable seat 13 has a circumferentially rotating movable seat. The movable seat is connected and fixed to the inner side of the guide frame 12. The outer side of the bidirectional threaded rod 15 is provided with a forward thread groove and a reverse thread groove respectively on the front and rear sides of the middle part of the guide frame 12. The threads of the forward thread groove and the reverse thread groove are opposite in direction, and the forward thread groove and the reverse thread groove are threadedly connected to the two movable seats 13 respectively. The servo motor 14 drives the bidirectional threaded rod 15 to rotate on the movable seat. By utilizing the threaded connection between the forward and reverse thread grooves on the bidirectional threaded rod 15 and the movable seat 13, and the linear limiting sliding of the guide frame 12 on the movable seat 13, the forward and reverse rotation of the bidirectional threaded rod 15 can drive the movable seat 13 to move in opposite directions within the guide frame 12.

[0046] A rotary motor 16 is fixed on the upper surface of the movable seat 13. A dispersing roller 17 is fixed at the output end of the rotary motor 16. The dispersing roller 17 is cylindrical and made of stainless steel. Multiple evenly distributed dispersing hollow cylinders 18 are connected to the outside of the dispersing roller 17. The number of dispersing hollow cylinders 18 is 30-40. The dispersing hollow cylinders 18 are cylindrical with a central hole and are used to disperse the refined cotton in the water and realize the discharge airflow.

During the rotation of the dispersing roller 17, the rotation of the annular groove and the annular seat 19 ensures that the annular seat 19 does not rotate synchronously during the rotation of the dispersing roller 17. During the operation of the vortex blower 20 to discharge airflow, the interconnection between the vortex blower 20, air pipe 21, hose 22, annular seat 19, air hole, dispersing roller 17 and dispersing hollow cylinder 18 allows the airflow to be discharged from the dispersing hollow cylinder 18, forming bubbles in the water and promoting the discharge of impurities.

[0049] The water inlet connector pipe 25 is connected to the upper outer surface of the alkali removal tank 1 and is connected to the faucet through a pipe. The outside of the water inlet connector pipe 25 is connected to the switch control valve 26. Opening the faucet and the switch control valve 26 will allow water to flow into the alkali removal tank 1.

[0050] The water storage base 23 is located below the sewage pipe 5. An internal partition is equipped with a filter screen 24, which is located above the opening at the other end of the sewage pipe 5. Sewage discharged from the sewage pipe 5 flows into the filter screen 24 on the water storage base 23, so that the filter screen 24 filters and isolates impurities and lint in the sewage, which facilitates the collection and reuse of lint. The alkaline sewage is stored in the water storage base 23. The water storage base 23 is connected to the outside of a drain pipe to discharge the stored water. A switch valve is connected to the outside of the drain pipe.

[0051] Filter screen 24 is a stainless steel filter screen used to filter impurities and refined cotton lint.

[0052] The control system of this equipment uses a programmable logic controller (PLC) to precisely control each component through a preset program. The specific control steps are as follows:

[0053] Initial state: The equipment is in standby mode, switch cover 2 is closed, and all hydraulic push rods and motors are in their initial positions.

[0054] Add refined cotton: The operator opens the switch cover 2, puts the refined cotton to be cleaned into the grid drying drum 4, and then closes the switch cover 2.

[0055] Alkali solution ejection: The PLC-controlled drive motor 3 starts, which drives the grid drying drum 4 to rotate, ejecting the alkali solution absorbed by the refined cotton and discharging it through the drain pipe 5 to the water storage base 23.

[0056] Water injection: The operator opens the faucet and switches the control valve 26, and water is discharged into the alkali removal tank 1 through the water inlet connector pipe 25.

[0057] Movement of the dispersing components: The PLC controls the hydraulic push rod 29 to drive the output motor 10, guide frame 12, moving seat 13, rotary motor 16, dispersing roller 17 and dispersing hollow cylinder 18 to move upward synchronously, so that the dispersing roller 17 and dispersing hollow cylinder 18 move above the alkali cleaning tank 1. Then, the PLC controls the hydraulic push rod 17 to push the loading plate 8, hydraulic push rod 29, output motor 10, guide frame 12, moving seat 13, rotary motor 16, dispersing roller 17 and dispersing hollow cylinder 18 to move horizontally, so that the dispersing roller 17 and dispersing hollow cylinder 18 move above the grid drying cylinder 4. Finally, the PLC controls the hydraulic push rod 29 to drive the above components to move downward, so that the dispersing roller 17 and dispersing hollow cylinder 18 are submerged in water.

[0058] Dispersing operation: The PLC controls the output motor 10 to drive the guide frame 12, dispersing roller 17, and dispersing hollow cylinder 18 to rotate inside the grid drying cylinder 4. At the same time, the PLC controls the rotary motor 16 to drive the dispersing hollow cylinder 18 to rotate. During the rotation and self-rotation, the PLC controls the servo motor 14 to drive the bidirectional threaded rod 15 to rotate in both directions, so that the moving seat 13 moves in opposite directions inside the guide frame 12, driving the dispersing roller 17 and the dispersing hollow cylinder 18 to fully disperse the refined cotton in the water, ensuring that the water is fully absorbed by the refined cotton and promoting the discharge of impurities in the refined cotton.

[0059] Inflation operation: The PLC controls the start of the vortex blower 20 to fill the hollow cylinder 18 with airflow, so that the gas is discharged from the hollow cylinder 18 and forms bubbles in the water. The bubbles move upward and attach to impurities, promoting the discharge of impurities.

[0060] Wastewater discharge: After water absorption is completed, the PLC controls the opening of the sewage pipe 5, and the sewage is discharged through the sewage pipe 5 to the water storage base 23. The filter screen 24 filters and isolates impurities and lint in the sewage.

[0061] Reset and spin-drying: After the sewage is discharged, the PLC controls the dispersing roller 17 and the dispersing hollow cylinder 18 to move upward and laterally to the side of the alkali cleaning box 1 to reset. Then, the switch cover 2 is closed, and the drive motor 3 is controlled to drive the grid spin-drying cylinder 4 to rotate, spin-drying the moisture in the refined cotton. Finally, the drain pipe 5 is opened to remove the remaining moisture.

[0062] Beneficial effects

[0063] The alkali removal equipment for refined cotton of this utility model uses a grid drying cylinder 4 to initially remove the alkali solution from the refined cotton, and then uses a dispersing roller 17 and a dispersing hollow cylinder 18 to fully disperse the refined cotton in the water, ensuring that the water is fully absorbed by the refined cotton and improving the alkali removal effect.

[0064] The air-filling component inflates air into the hollow cylinder 18, forming bubbles in the water, which promotes the discharge of impurities and effectively cleans impurities from refined cotton.

[0065] The filter screen 24 inside the water storage base 23 filters and isolates impurities and lint in the sewage, making it easy to collect and reuse the lint, while storing alkaline sewage, thus reducing environmental pollution.

[0066] The equipment adopts a PLC control system, which realizes the automated operation of each component, improving production efficiency and ease of operation.
