Description

Technical Field

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

[0002] Refined cotton is the basic material of cotton cellulose. It is a white, flocculent substance made from cotton linters through alkaline cooking, rinsing, milling and dehydration, and air-drying. After rinsing, refined cotton is milled and dehydrated, which facilitates subsequent air-drying.

[0003] The prior art CN218034047U discloses a refined cotton dewatering device. Although the document proposes a technical solution using centrifugal dewatering and airflow drying, after the refined cotton is dewatered, workers still need to open the box door to remove the material from the mesh cylinder, which is slow. At the same time, the wastewater generated by dewatering contains a large amount of lint, which can easily cause blockage during drainage and affect the normal discharge of wastewater. Therefore, we propose a refined cotton dewatering device to solve this defect of the prior art. Utility Model Content

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

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

An output motor is provided at the center of the cap. A cleaning brush is provided at the output end of the output motor. The cleaning brush contacts the outside of the filter screen cylinder. A water pumping and draining assembly is provided on the filter screen cylinder.

[0008] Using the above technical solution, refined cotton is stored in a mesh cylinder. During the dehydration of the refined cotton, the drive motor drives the mesh cylinder and the mesh plate in the limiting slide groove to rotate synchronously, centrifugally dehydrating the stored refined cotton. The wastewater generated is discharged into the water storage cylinder through the drain pipe. The filter cylinder filters and isolates the lint in the wastewater. During the filtration process, the output motor on the cover drives the cleaning brush to rotate, cleaning the lint on the outside of the filter cylinder to prevent drainage blockage. The filtered water is discharged through the water pumping and drainage components, ensuring smooth drainage and realizing the collection and reuse of lint.

[0009] After dehydration, the refined cotton can be lifted by raising the lifting component to move the screen and rotating seat upward, thereby improving the feeding efficiency.

[0010] As a preferred technical solution of this utility model, the lifting component includes a storage seat disposed outside the dewatering outer cylinder, a support frame disposed outside the storage seat, a hydraulic push rod disposed at the upper end of the support frame, a connecting rod disposed at the push rod of the hydraulic push rod, the lower end of the connecting rod rotating with the upper end of the rotating seat, and a sealing cover disposed outside the connecting rod to seal the upper opening of the dewatering outer cylinder.

[0011] Using the above technical solution, the hydraulic push rod on the support frame drives the connecting rod, rotating seat, sealing cover and screen plate to move upward synchronously. During the upward movement of the screen plate, the refined cotton falls into the storage seat for storage. It should be noted that when feeding the refined cotton into the screen cylinder, the sealing cover is moved upward to create a feeding gap with the outer dewatering cylinder, so that the refined cotton can be fed into the screen cylinder. During the centrifugal dewatering of the screen cylinder, the sealing cover seals the outer dewatering cylinder to prevent the refined cotton from being thrown out of the screen cylinder during centrifugal dewatering.

[0012] In a preferred embodiment of this utility model, the upper end of the mesh cylinder is sealed to the upper end of the dehydration outer cylinder, and the mesh plate separates from the mesh cylinder when the push rod of the hydraulic push rod is in a fully retracted state.

[0013] By adopting the above technical solution, the screen is moved to the top, which facilitates the unloading and cleaning of the remaining refined cotton on the screen.

[0014] As a preferred embodiment of this utility model, the mesh plate and the outside of the mesh cylinder are provided with a plurality of perforations, and the perforations on the mesh plate and the mesh cylinder are interconnected.

[0015] Using the above technical solution, the perforation facilitates centrifugal dehydration and drainage.

[0016] As a preferred embodiment of this utility model, the connection between the drain pipe and the dehydration outer cylinder is aligned.

[0017] By adopting the above technical solution, it can be ensured that the wastewater inside the dewatering outer cylinder can be fully discharged through the drain pipe.

[0018] As a preferred embodiment of this utility model, the inner side of the cleaning brush is provided with soft bristles, and the cleaning brush contacts the surface of the filter cylinder through the soft bristles.

[0019] Using the above technical solution, the soft brush bristles clean the lint from the filter cylinder while avoiding damage to the filter cylinder.

[0021] Using the above technical solution, the water pump works by using the pumping pipe to extract the filtered water from the filter cylinder and discharge it through the drainage pipe.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] Refined cotton is stored in a mesh cylinder. The stored cotton is centrifuged and dehydrated by the synchronous rotation of the mesh cylinder and mesh plate. The resulting wastewater is discharged into a water storage cylinder. The filter cylinder filters and isolates the lint in the wastewater. During the filtration process, the cleaning brush rotates to clean the lint on the outside of the filter cylinder to prevent drainage blockage. The filtered water is discharged through the water pumping and drainage components to ensure smooth drainage and realize the collection and reuse of lint.

[0024] After dehydration, the screen can be raised by lifting the lifting component, which can lift the dehydrated refined cotton and improve the feeding efficiency. Attached Figure Description

[0032] 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.

[0033] Please see Figures 1 to 4 The cotton dewatering equipment in this embodiment includes a dewatering outer cylinder 1, a drive motor 2, a mesh cylinder 3, a limiting slide 4, a mesh plate 5, a rotating seat 6, a lifting component, a drain pipe 11, a water storage cylinder 12, a filter cylinder 13, a cover 14, an output motor 15, a cleaning brush 16, and a water pumping and draining component.

[0034] The outer dewatering cylinder 1 is the main shell of the entire equipment. It is made of high-strength, corrosion-resistant metal materials, such as stainless steel, to ensure the stability and durability of the equipment during long-term use. It is cylindrical in shape and has enough space inside to accommodate the mesh cylinder 3 and other components.

[0035] The lower end of the dehydration outer cylinder 1 is fixed with a support base so that the dehydration outer cylinder 1 can be placed stably on the ground.

[0036] The drive motor 2 is fixed at the center of the lower end surface of the dewatering outer cylinder 1 and is connected by bolts. The drive motor 2 is a high-performance servo motor with adjustable speed, large torque and stable operation, which can provide strong power for the rotation of the screen cylinder 3.

[0037] The mesh cylinder 3 is located inside the dewatering outer cylinder 1 and is fixedly connected to the output shaft of the drive motor 2. The fixing is achieved by a key connection to ensure stable rotation under the drive of the drive motor 2. The mesh cylinder 3 adopts a metal mesh structure.

[0038] The inner wall of the mesh cylinder 3 has a pair of elongated sliding grooves 4 that extend to the bottom. A mesh plate 5 is slidably connected between the sliding grooves 4. The diameter of the mesh plate 5 is equal to the inner diameter of the mesh cylinder 3. It adopts the same metal mesh structure as the mesh cylinder 3 to ensure the consistency of the dewatering effect. The mesh plate 5 has multiple perforations that are interconnected with the perforations on the mesh cylinder 3 to facilitate the smooth discharge of water during centrifugation. The size of the perforations is designed according to the size of the refined cotton and the dewatering requirements to ensure that water can pass through smoothly while preventing the refined cotton from leaking out.

[0039] A rotating seat 6 is fixed to the center of the upper surface of the mesh plate 5. The rotating seat 6 is made of metal and is cylindrical in shape. It is fixedly connected to the mesh plate 5 by welding. The function of the rotating seat 6 is to provide a connection point for the lifting component and to ensure that the mesh plate 5 rotates synchronously when the mesh cylinder 3 rotates.

[0040] The outer dewatering cylinder 1 is equipped with a lifting assembly that is connected to and rotates with the rotating seat 6.

[0041] The lifting assembly is used to lift and feed the refined cotton on the mesh plate 5, and includes a storage seat 10, a support frame 7, a hydraulic push rod 8, a connecting rod, and a sealing cover 9.

[0042] The storage seat 10 is fixed to the outside of the dewatering outer cylinder 1 with the same center. It is used to store the refined cotton after dewatering. It is made of metal material and has a smooth inner surface, which facilitates the sliding and storage of refined cotton.

[0043] The support frame 7 is fixed to the outside of the storage seat 10. It adopts a metal frame structure and has sufficient strength and stability to provide support for the hydraulic push rod 8.

[0044] The hydraulic push rod 8 is installed and fixed on the upper surface of the support frame 7 by bolts. The hydraulic push rod 8 is made of high-performance hydraulic cylinder, which has the characteristics of large thrust, adjustable stroke and smooth operation. A connecting rod is fixed at its push rod. The connecting rod adopts a metal rod structure. The lower end of the connecting rod is rotatably connected to the upper end of the rotating seat 6 with the same center. The bearing connection method is adopted to ensure that the rotating seat 6 can rotate freely when the hydraulic push rod 8 drives the connecting rod to move up and down.

[0045] The sealing cap 9 is fixed to the outside of the connecting rod and is used to seal the upper opening of the dewatering outer cylinder 1. The sealing cap 9 is made of rubber material and has good sealing performance, which can effectively prevent refined cotton from being thrown out of the mesh cylinder 3 during centrifugal dewatering. When feeding refined cotton into the mesh cylinder 3, the sealing cap 9 is moved upward by the hydraulic push rod 8, so that there is a feeding gap between the sealing cap 9 and the dewatering outer cylinder 1, and the refined cotton can be fed into the mesh cylinder 3. When the mesh cylinder 3 rotates for centrifugal dewatering, the sealing cap 9 seals the dewatering outer cylinder 1.

[0046] The upper end of the mesh cylinder 3 is sealed to the upper end of the dewatering outer cylinder 1. When the push rod of the hydraulic push rod 8 is in a fully retracted state, the mesh plate 5 separates from the mesh cylinder 3 and moves to the top, making it easier to clean the remaining refined cotton on the mesh plate 5.

[0047] Please see Figures 4 to 6 The lower end surface of the dehydration outer cylinder 1 is connected to a drain pipe 11. The drain pipe 11 is flush with the connection of the dehydration outer cylinder 1 and is made of metal pipe with a smooth inner surface to facilitate the smooth discharge of sewage. The other end of the drain pipe 11 is connected to a water storage cylinder 12. The water storage cylinder 12 is a cylindrical metal container with sufficient volume to store the sewage generated during the dehydration process.

[0048] A filter screen cylinder 13 is fixed to the bottom wall of the water storage cylinder 12 at the same center. The filter screen cylinder 13 adopts a metal mesh structure, and its mesh size is designed according to the particle size of the lint, which can effectively filter the lint in the sewage.

[0049] A cap 14 is detachably installed on the upper end of the water storage cylinder 12. The cap 14 is made of metal and is fixed to the water storage cylinder 12 by a threaded connection, which facilitates disassembly and installation and makes it convenient to clean and maintain the filter cylinder 13. An output motor 15 is fixed on the cap 14 at the same center. The output motor 15 is a small DC motor with adjustable speed and stable operation. A cleaning brush 16 is fixed to the output end of the output motor 15. The inner side of the cleaning brush 16 is provided with soft bristles made of nylon material, which is soft and wear-resistant. The cleaning brush 16 contacts the surface of the filter cylinder 13 through the soft bristles. Driven by the output motor 15, the cleaning brush 16 can rotate to clean the lint on the outside of the filter cylinder 13 and prevent drainage blockage.

[0050] The filter cylinder 13 is equipped with a water pumping and drainage assembly for discharging the filtered water. The water pumping and drainage assembly includes a water pump 17, a water pumping pipe 18, and a drainage pipe 19.

[0051] The water pump 17 is a high-performance centrifugal pump, which has the characteristics of large pumping capacity, high head and stable operation. The water pump 17 has a water pumping pipe 18 connected to the bottom of the filter screen cylinder 13 at the water pump inlet. The water pumping pipe 18 is made of metal pipe with a smooth inner surface to facilitate the smooth pumping of water. The water pump 17 has a drain pipe 19 connected to the drain outlet. The other end of the drain pipe 19 is connected to the sewage discharge system to discharge the filtered water from the equipment.

[0052] To achieve automated operation of the equipment, the refined cotton dewatering equipment of this utility model can be equipped with a control system, which includes a controller and an operation panel.

[0053] The controller is a programmable logic controller (PLC), which has powerful logic control and data processing capabilities. The controller is connected to the drive motor 2, hydraulic push rod 8, output motor 15 and water pump 17 via wires to achieve precise control of each component.

[0054] The control panel is located on the outside of the equipment and adopts a touch screen design, which is intuitive and easy to operate. The control panel is equipped with various operation buttons and display interface. Operators can set the equipment's operating parameters, such as dehydration time, speed, lifting height, etc., and monitor the equipment's operating status in real time through the control panel.

[0055] Usage steps,

[0056] Feeding: Start the hydraulic push rod 8 to move the sealing cover 9 upward, so that there is a feeding gap between the sealing cover 9 and the dewatering outer cylinder 1. Put the refined cotton to be dewatered into the mesh cylinder 3 through the feeding gap. After feeding is completed, the hydraulic push rod 8 moves the sealing cover 9 downward to seal the dewatering outer cylinder 1.

[0057] Dehydration: Start the drive motor 2, which drives the mesh cylinder 3 and mesh plate 5 to rotate synchronously, centrifugally dehydrating the refined cotton. The wastewater generated during the dehydration process enters the bottom of the dehydration outer cylinder 1 through the perforations on the mesh plate 5 and mesh cylinder 3, and then is discharged into the water storage cylinder 12 through the drain pipe 11.

[0058] Filtration and cleaning: After the sewage enters the water storage tank 12, it is filtered through the filter screen 13. The lint is isolated outside the filter screen 13. At the same time, the output motor 15 is started, which drives the cleaning brush 16 to rotate and clean the lint outside the filter screen 13 to prevent drainage blockage.

[0059] Drainage: The controller starts the water pump 17, which pumps the filtered water out of the filter screen cylinder 13 through the water pumping pipe 18 and discharges it out of the equipment through the drainage pipe 19.

[0060] Feeding: After dehydration is completed, the hydraulic push rod 8 is started. The hydraulic push rod 8 drives the connecting rod, rotating seat 6 and screen plate 5 to move upward. During the upward movement of screen plate 5, the dehydrated refined cotton falls into the storage seat 10 for storage. When screen plate 5 moves to the top, it is convenient to feed and clean the remaining refined cotton on screen plate 5.

[0061] Beneficial effects

[0062] This utility model discloses a refined cotton dewatering device. Refined cotton is stored in a mesh cylinder 3. During dewatering, a drive motor 2 rotates the mesh cylinder 3 and the mesh plate 5 within the limiting slide groove 4 synchronously, centrifugally dewatering the stored refined cotton. The resulting wastewater is discharged into a water storage cylinder 12 through a drain pipe 11. A filter cylinder 13 filters and isolates lint from the wastewater. During filtration, an output motor 15 on the cover 14 drives a cleaning brush 16 to clean lint from the outside of the filter cylinder 13, preventing drainage blockage. The filtered water is discharged through a pumping and draining assembly, ensuring smooth drainage and enabling the collection and reuse of lint. After dewatering, a lifting assembly moves the mesh plate 5 and the rotating seat 6 upwards, lifting the dewatered refined cotton and improving feeding efficiency. This equipment has a reasonable structure, is easy to operate, and effectively solves the problems of difficult unloading and drainage blockage in existing technologies, improving the quality and efficiency of refined cotton production.
