Description

Technical Field

[0001] This invention relates to the field of dehydration equipment technology, specifically a dehydration device for degreased cotton used in spunlace nonwoven fabrics. Background Technology

[0002] In the production process of spunlace nonwoven fabric, degreased cotton is a key raw material, and its dehydration efficiency and quality directly affect the performance of the final product and the production cost. Traditional dehydration devices for degreased cotton in spunlace nonwoven fabric mainly rely on the principle of centrifugal dehydration, that is, the centrifugal force generated by the high-speed rotating inner cylinder throws the water in the material out through the filter holes on the side wall of the inner cylinder, thereby achieving the dehydration of the material.

[0003] However, traditional dehydration devices rely solely on centrifugal force for dehydration, resulting in long processing cycles. This is especially true when processing high-moisture-content degreased cotton, where dehydration efficiency drops significantly, leading to low production efficiency. Furthermore, the dehydrated material often requires an additional drying step to further remove residual moisture, which undoubtedly increases the complexity and cost of the production process.

[0004] Based on this, a dehydration device for degreased cotton used in spunlace nonwoven fabrics is provided, which can eliminate the drawback of long processing cycles in existing devices. Summary of the Invention

[0009] Preferably, the scraper has an air passage two and an air passage three inside, the air passage three is connected to the air passage one on the side of the inner cylinder through the air passage two, and the scraper has a plurality of air holes one through it, the air holes one being connected to the inside of the air passage three.

[0011] Preferably, the lifting member includes a lifting plate and a fixed cylinder fixed in the middle of the lifting plate. The inner wall of the fixed cylinder is slidably connected to the outer wall of the limiting ring. The outer diameter of the lifting plate is the same as the inner diameter of the inner cylinder.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] The core technical concept of this invention lies in integrating centrifugal dehydration and hot air drying functions to achieve simultaneous dehydration and drying, significantly shortening the processing cycle and improving production efficiency, while ensuring thorough dehydration and drying quality of the materials; the inner cylinder stabilizing component design effectively absorbs vibration, prevents swaying and displacement, and ensures stable operation of the device; the scraper and hot air auxiliary cleaning system automatically remove impurities from the inner wall, reducing manual maintenance costs.

[0027] In one embodiment, such as Figures 1-7 As shown, a dehydration device for degreased cotton used in spunlace nonwoven fabric includes an outer cylinder 1, a water collection frame 11 fixed at the lower end of the outer cylinder 1, an inner cylinder 2 disposed inside the outer cylinder 1, the inner cylinder 2 being rotatably mounted on the upper end of the water collection frame 11, a plurality of filter holes being opened through the side wall of the inner cylinder 2, a drain outlet being opened at the lower end of the water collection frame 11, a drain pipe 14 being installed at the drain outlet of the water collection frame 11, a bracket 12 being fixed at the lower end of the water collection frame 11, a fixing pipe 13 being fixed in the middle of the bracket 12, a drive structure for driving the inner cylinder 2 to rotate being installed on the bracket 12 and the fixing pipe 13, and a lifting component 3 being placed inside the inner cylinder 2; The fixed pipe 13 is equipped with a fan and a heater 131, and the inner cylinder 2 is equipped with a drying structure for drying materials. The drying structure is connected to the fixed pipe 13. The outer wall of the inner cylinder 2 is provided with a number of stabilizing components 21 around its central circumference to ensure stable rotation. Between every two stabilizing components 21, there is a scraper 22 for removing impurities attached to the inner wall of the outer cylinder 1 and the water collection frame 11. The scrapers 22 are fixedly installed on the outer wall of the inner cylinder 2.

[0028] In this embodiment, the lifting member 3 is first placed inside the inner cylinder 2, followed by the material. Then, the driving structure rotates the inner cylinder 2 and the lifting member 3, causing the material to rotate. Under centrifugal force, the moisture in the material is flung out through the filter holes on the side wall of the inner cylinder 2, enters the water collection frame 11, and is then discharged through the drain pipe 14. Simultaneously, the fan and heater 131 inside the fixed pipe 13 are activated. The fan blows air in, which is then heated by the heater 131 to form hot air. This hot air dries the material inside the inner cylinder 2 through the drying structure. During the dehydration and drying process, the scraper 22 on the outer wall of the inner cylinder 2 rotates with the inner cylinder 2, removing impurities adhering to the inner walls of the outer cylinder 1 and the water collection frame 11. After dehydration and drying are complete, the driving structure, fan, and heater 131 are stopped, and the material is removed from the inner cylinder 2 using the lifting member 3.

[0029] In an optional embodiment, the drive structure includes a motor 41 mounted on a bracket 12, with a large gear 42 fixedly connected to the output end of the motor 41. The large gear 42 meshes with a small gear ring 43, which is fixedly mounted on the outer wall of a connecting pipe 44. The connecting pipe 44 is rotatably mounted on the upper end of a fixed pipe 13 and fixedly mounted in the middle of the lower end of the inner cylinder 2. The connecting pipe 44 corresponds to the position of the drying structure.

[0030] It should be noted that the output end of motor 41 is fixedly connected to large gear 42, which rotates along with it. Since large gear 42 meshes with small gear ring 43, according to the principle of gear transmission, when two meshing gears rotate, the large gear drives the small gear ring to rotate, and their rotational speed is inversely proportional to the number of teeth. Large gear 42 has more teeth than small gear ring 43, so the rotational speed of small gear ring 43 is faster than that of large gear 42, achieving speed-increasing transmission.

[0031] The small toothed ring 43 is fixedly installed on the outer wall of the connecting pipe 44. When the small toothed ring 43 rotates, it will drive the connecting pipe 44 to rotate as well. The connecting pipe 44 is rotatably installed on the upper end of the fixed pipe 13, ensuring that the connecting pipe 44 can rotate stably around its own axis. Since the connecting pipe 44 is fixedly installed in the middle of the lower end of the inner cylinder 2, the rotation of the connecting pipe 44 will be directly transmitted to the inner cylinder 2, causing the inner cylinder 2 to rotate as well.

[0032] In an optional embodiment, the drying structure includes a connecting hole 201 located in the middle of the lower end of the inner cylinder 2. The air inlet end of the connecting hole 201 is connected to the inside of the connecting pipe 44, and the air outlet end of the connecting hole 201 is connected to the air inlet ends of a plurality of air passages 202. The plurality of air passages 202 are arranged in a circular array around the center of the inner cylinder 2 at the bottom and sides of the inner cylinder 2, and each air passage 202 on the side of the inner cylinder 2 corresponds to a scraper 22.

[0033] It should be noted that the fan in the fixed pipe 13 blows air in, which is heated by the heater 131 to form hot air. The hot air can enter the connecting pipe 44 through the fixed pipe 13, and then enter the internal airflow channel of the inner cylinder 2 through the connecting hole 201.

[0034] Hot air enters the air inlet of several air channels 202 from the outlet end of the connection hole 201. These air channels 202 are arranged in a circumferential array around the center of the inner cylinder 2 at the bottom and sides of the inner cylinder 2. The hot air flows and is divided within the air channels 202. The air channels 202 at the bottom of the inner cylinder 2 heat the bottom of the inner cylinder 2 with hot air, while the air channels 202 on the sides heat the inner wall of the inner cylinder 2. The material is heated and dried from different directions and positions, so that a relatively uniform thermal field is formed inside the entire inner cylinder 2, ensuring that all parts of the material are fully heated.

[0035] In an optional embodiment, the scraper 22 is provided with air passage 203 and air passage 3 204. Air passage 3 204 is connected to air passage 1 202 on the side of the inner cylinder 2 through air passage 203. A plurality of air holes 1 205 are provided through the scraper 22. The air holes 1 205 are connected to the inside of air passage 3 204.

[0036] It should be noted that, since the air passage 3 204 inside the scraper 22 is connected to the air passage 1 202 on the side of the inner cylinder 2 through the air passage 2 203, the hot air entering the air passage 1 202 on the side of the inner cylinder 2 will continue to flow into the air passage 3 204, and then be blown out through several air holes 1 205 connected to the inside of the air passage 3 204.

[0037] On the one hand, the hot air inside the outer cylinder 1 further enhances the drying effect on the material, causing the moisture on the surface and inside of the material to evaporate more quickly, thus improving the dehydration and drying efficiency. On the other hand, during the blowing process, the hot air exerts a certain impact force on the impurities adhering to the inner wall of the outer cylinder 1 and the water collection frame 11. Combined with the rotating scraping action of the scraper 22, it can more effectively remove impurities from the inner wall, preventing long-term adhesion of impurities from affecting the normal operation and service life of the device. At the same time, it can also ensure the cleanliness and hygiene of the inside of the device, avoiding contamination of the material by impurities. Moreover, this method of hot air-assisted scraping of impurities, compared with simply relying on mechanical scraping by the scraper, can reduce the frictional resistance between the scraper and the inner wall, reduce scraper wear, and extend the service life of the scraper.

[0038] In an optional embodiment, an air pipe 24 is fixed in the middle of the inner cylinder 2. The air pipe 24 is connected to a connecting pipe 44 through a connecting hole 201. A plurality of limiting rings 25 are fixed in an array on the outer wall of the air pipe 24. A plurality of air holes 241 are provided between every two limiting rings 25. The plurality of air holes 241 are opened through the side wall of the air pipe 24 and are connected to the inside of the air pipe 24. The air pipe 24 is adapted to the lifting member 3.

[0039] It should be noted that during the dehydration and drying operation, the fan inside the fixed pipe 13 sends the hot air heated by the heater 131 into the connecting pipe 44, and the hot air enters the air pipe 24 through the connecting hole 201. The air pipe 24 is fixed in the middle of the inner cylinder 2, and its position is relatively stable, which can provide a stable channel for the delivery of hot air.

[0040] After the hot air enters the trachea 24, several limiting rings 25 are fixed to the side wall of the trachea 24. A relatively independent area is formed between every two limiting rings 25. Each area is provided with several air holes 241 that communicate with the inside of the trachea 24. The hot air will be blown out evenly from these air holes 241 and diffused in all directions.

[0041] In an optional embodiment, the lifting member 3 includes a lifting plate 31 and a fixing cylinder 33 fixed in the middle of the lifting plate 31. The inner wall of the fixing cylinder 33 is slidably connected to the outer wall of the limiting ring 25. The outer diameter of the lifting plate 31 is the same as the inner diameter of the inner cylinder 2. A connecting member is provided at the bottom of the inner cylinder 2 and the lower end of the lifting member 3 to connect the two.

[0042] It should be noted that when the lifting component 3 is placed into the inner cylinder 2, the inner wall of the fixed cylinder 33 is slidably connected to the outer wall of the limiting ring 25. This design provides precise guidance for the installation of the lifting component 3. The operator can easily slide the fixed cylinder 33 down along the limiting ring 25, so that the lifting component 3 is accurately placed in the predetermined position inside the inner cylinder 2, avoiding any offset or jamming of the lifting component 3 during placement, thus improving the efficiency and accuracy of installation.

[0043] The outer diameter of the lifting plate 31 is the same as the inner diameter of the inner cylinder 2. This design allows the lifting plate 31 to fit tightly against the inner wall of the inner cylinder 2. During the dehydration and drying process, when the inner cylinder 2 rotates together with the lifting component 3, the tight fit between the lifting plate 31 and the inner wall of the inner cylinder 2 prevents material from leaking out from the gaps between the lifting plate 31 and the inner wall of the inner cylinder 2. This ensures that the material is always within the relatively enclosed space formed by the inner cylinder 2 and the lifting component 3, guaranteeing the normal operation of the dehydration and drying process. At the same time, this tight fit also helps the lifting component 3 to better follow the rotation of the inner cylinder 2, reducing swaying and friction caused by gaps, and reducing energy loss and equipment wear.

[0044] In an optional embodiment, the connector includes a plurality of docking grooves 32 and a plurality of docking blocks 23. The plurality of docking grooves 32 are arranged in a circular array around the center of the lifting member 3 at the lower end of the lifting member 3, and the plurality of docking blocks 23 are arranged in a circular array around the center of the inner cylinder 2 and fixed to the bottom of the inner cylinder 2. Each docking groove 32 is matched with a docking block 23.

[0045] It should be noted that when installing the lifting component 3, it is slowly lowered into the inner cylinder 2. Because the docking grooves 32 are arranged in a circular array around the center of the lifting component 3, and the docking blocks 23 are fixed in a circular array around the center of the inner cylinder 2, this symmetrical and regular layout allows operators to easily locate the docking position. When the lifting component 3 falls to a certain height, each docking block 23 can accurately embed into its matching docking groove 32, achieving precise docking. This docking method is not only simple to operate but also allows for rapid connection between the lifting component 3 and the inner cylinder 2, greatly improving installation efficiency. It is particularly suitable for large-scale production or scenarios requiring frequent installation and disassembly of the lifting component 3.

[0046] From a stability perspective, the multiple docking slots 32 and docking blocks 23 cooperate to form a multi-point fixed structure. When the inner cylinder 2 drives the lifting component 3 to rotate at high speed for dehydration and drying, this multi-point fixing can effectively disperse centrifugal force and other forces, preventing the lifting component 3 from loosening, shifting, or even detaching due to excessive force at a single fixed point. After each docking block 23 is embedded in the docking slot 32, it can effectively restrict the lifting component 3 in both the vertical and horizontal directions, ensuring that the lifting component 3 is always stably positioned in the predetermined position within the inner cylinder 2. This ensures that the material can undergo dehydration and drying in a relatively stable environment, improving the reliability and stability of the entire device.

[0047] When the material needs to be removed after dehydration and drying, simply apply a certain external force upwards to pull the lifting component 3 out of the inner cylinder 2. Because the mating groove 32 and the mating block 23 have a certain gap and are not completely rigidly connected, the lifting component 3 can be separated from the inner cylinder 2 relatively easily. Furthermore, this detachable connection method facilitates separate cleaning and maintenance of the lifting component 3 and the inner cylinder 2.

[0048] Furthermore, the structural design of the mating groove 32 and the mating block 23 can be optimized according to actual needs. For example, the head of the mating block 23 can be designed as an arc, and the entrance of the mating groove 32 can also be made with a corresponding arc transition. This can guide the mating process, making it easier for the mating block 23 to enter the mating groove 32 and further reducing the installation difficulty. At the same time, some anti-slip textures or materials with a certain friction can be added to the contact surfaces of the mating block 23 and the mating groove 32 to enhance the friction between them and improve the stability of the connection.

[0049] In an optional embodiment, a lifting ring 34 is fixed to the upper end of the fixed cylinder 33.

[0050] It should be noted that when installing or removing the lifting component 3 from the inner cylinder 2, the lifting component 3 itself may have a certain weight, especially when the inner cylinder 2 is large and the lifting component 3 carries a lot of material. Directly moving the lifting component 3 by hand is not only laborious but also makes it difficult to accurately control its position and direction. The existence of the lifting ring 34 provides the operator with a convenient point of force application. The operator can use tools such as hooks and ropes to pass through the lifting ring 34 and, with the help of lifting equipment or manual traction, easily lift, move, and place the lifting component 3 to the designated position.

[0051] In an optional embodiment, the stabilizer 21 includes a damping spring 211 and a damping rod 212 fixed to the outer wall of the inner cylinder 2. The damping rod 212 is sleeved inside the damping spring 211. A connecting block 213 is fixed to one end of the damping spring 211 and the damping rod 212 away from the inner cylinder 2. A roller 214 is rotatably mounted on one end of the connecting block 213 near the inner wall of the outer cylinder 1. An annular groove 15 that cooperates with the roller 214 is opened on the inner wall of the outer cylinder 1.

[0052] It should be noted that when the inner cylinder 2 begins to rotate, due to the gap between the inner cylinder 2 and the outer cylinder 1, the inner cylinder 2 may experience some swaying and displacement during high-speed rotation. At this time, the damping spring 211 and damping rod 212 fixed to the outer wall of the inner cylinder 2 begin to function. The damping spring 211 is elastic and can generate a counter-force when the inner cylinder 2 sways, attempting to pull the inner cylinder 2 back to its original position, thus providing a buffering and stabilizing effect. The damping rod 212, fitted inside the damping spring 211, further enhances this stabilizing effect. It can limit the extension and contraction direction of the damping spring 211, preventing the damping spring 211 from bending or twisting under force, ensuring that the elastic force can be accurately applied to the inner cylinder 2, effectively suppressing the swaying of the inner cylinder 2.

[0053] As the inner cylinder 2 rotates, the roller 214 rolls within the annular groove 15. Compared to sliding friction, this rolling friction greatly reduces the friction between the inner cylinder 2 and the outer cylinder 1, allowing the inner cylinder 2 to rotate more smoothly, reducing energy loss, and also reducing heat and wear caused by friction, thus extending the service life of the device.

[0054] The design of the annular groove 15 provides a fixed rolling track for the roller 214, ensuring that the roller 214 always rolls along the predetermined path and will not deviate from the track. This further ensures the stability of the inner cylinder 2 during rotation, enabling the inner cylinder 2 to rotate uniformly and stably around its central axis. This ensures that the material inside the inner cylinder 2 is evenly subjected to centrifugal force and hot air, improving the uniformity and effect of dehydration and drying.

[0055] The above embodiment discloses a dehydration device for degreased cotton used in spunlace nonwoven fabric. In this device, a motor 41 installed on a bracket 12 is started. The output end of the motor 41 drives a large gear 42 to rotate. The large gear 42 meshes with a small toothed ring 43 fixed on the outer wall of the connecting pipe 44 to achieve speed-increasing transmission, causing the connecting pipe 44 to rotate accordingly, which in turn drives the inner cylinder 2 to rotate at high speed on the water collection frame 11.

[0056] Under the action of centrifugal force, the water in the material is thrown out through the filter holes on the side wall of the inner cylinder 2, enters the water collection frame 11, and is then discharged out of the device through the drain pipe 14 at the lower end of the water collection frame 11, thus achieving the initial dehydration of the material.

[0057] Simultaneously, the fan and heater 131 inside the fixed pipe 13 are activated. The fan blows air in, which is then heated by the heater 131 to form hot air. The hot air enters the connecting hole 201 at the lower middle of the inner cylinder 2 through the connecting pipe 44, and then flows to several air passages 202 arranged in a circular array around the center of the inner cylinder 2 at the bottom and sides of the inner cylinder 2.

[0058] Hot air is blown out from air duct 202 to heat and dry the material inside the inner cylinder 2 from all directions. At the same time, some of the hot air is blown out from the air hole 205 on the scraper 22 through air ducts 203 and 204 inside the scraper 22, further enhancing the drying effect and impacting and assisting in the scraping away of impurities attached to the inner wall of the outer cylinder 1 and the water collection frame 11.

[0059] The outer wall of the inner cylinder 2 is provided with stabilizing components 21, including damping springs 211, damping rods 212, connecting blocks 213, and rollers 214. When the inner cylinder 2 rotates, the damping springs 211 and damping rods 212 provide cushioning and stabilization, preventing the inner cylinder 2 from swaying or shifting. The rollers 214 roll within the annular grooves 15 on the inner wall of the outer cylinder 1, reducing friction and ensuring smooth rotation of the inner cylinder 2.

[0060] A scraper 22 is provided between every two stabilizing components 21. The scraper 22 rotates with the inner cylinder 2, mechanically scraping away impurities adhering to the inner wall of the outer cylinder 1 and the water collection frame 11. At the same time, the hot air blown out by the scraper 22 generates an impact force on the impurities, which, together with the scraping action of the scraper, more effectively removes impurities and keeps the inside of the device clean.

[0061] After dehydration and drying are completed, stop motor 41, fan and heater 131. Use lifting ring 34 on lifting member 3, and tools such as hooks or ropes to remove lifting member 3 together with the dehydrated and dried material from inner cylinder 2.

[0062] Any aspects of this invention not described in detail are well-known to those skilled in the art.

[0063] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
