Abstract
Description
Technical Field
[0001] This utility model belongs to the field of materials engineering technology, specifically a drying device for surgical gown-grade breathable PBT copolyester. Background Technology
[0002] PBT copolyester has excellent moisture permeability, effectively allowing water vapor to pass through, ensuring wearer comfort and reducing dampness. This is especially important in surgical gowns, which need to remain dry and comfortable. PBT copolyester has high strength and toughness, capable of withstanding various stresses and stretches in the medical environment, ensuring the durability and reliability of surgical gowns. PBT also has good resistance to many chemicals, which is particularly important for the various disinfectants and medications that may be encountered in the operating room.
[0003] The drying principle of PBT copolyester mainly involves two aspects: heat exchange and moisture removal. Moisture in PBT is removed by means of hot air or vacuum to ensure the material is dry enough before processing, preventing any impact on the final product's performance. Heat is transferred to the PBT material using heat conduction or convection principles to promote moisture evaporation.
[0004] Existing drying devices, when processing PBT copolyester, cause uneven heating of the PBT copolyester because the PBT copolyester is packed too densely inside the drying device, resulting in some parts of the PBT copolyester being blocked, which affects the circulation of hot air and the dissipation of moisture. Therefore, a drying device for surgical gown-grade breathable PBT copolyester is proposed to address the above problems. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, existing drying devices, when processing PBT copolyester, cause some parts of the PBT copolyester to be blocked due to the excessively dense stacking of PBT copolyester inside the drying device, which affects the circulation of hot air and the dissipation of moisture, resulting in uneven heating of the PBT copolyester. This utility model proposes a drying device for surgical gown-grade breathable PBT copolyester.
[0006] The technical solution adopted by this utility model to solve its technical problem is a drying device for surgical gown-grade breathable PBT copolyester, including a heating tank. A top cover is threaded onto the top of the heating tank. A drive motor is fixedly mounted on the top of the top cover. A driving bevel gear is fixedly mounted on the output end of the drive motor. A driven bevel gear is externally meshed with the driving bevel gear. A rotating rod is fixedly mounted on the bottom of the driven bevel gear. A driving gear is fixedly mounted on the outside of one end of the rotating rod. A fixed gear is fixedly mounted on the bottom of the driving gear. A first fixing block is fixedly mounted on the bottom of the fixed gear. The inside of the first fixing block is rotatably mounted on the outside of one end of the rotating rod. Both outer sides of the first fixing block are fixedly mounted... Equipped with connecting rods, each of the connecting rods has a second fixing block fixedly mounted on its outer side at one end. A driven gear is fixedly mounted on the outer side of one end of the second fixing block, and a stirring blade is fixedly mounted on the outer side of the other end of the second fixing block. The outer sides of the driven gears are meshed with the outer sides of the fixed gears. A drive motor drives the active bevel gear and the driven bevel gear to rotate. When the active bevel gear and the driven bevel gear rotate, they drive the stirring blade at the bottom to rotate. The rotation of the stirring blade achieves the effect of stirring the PBT copolyester during drying, preventing the PBT copolyester from piling up and causing uneven heating. This ensures that each particle is heated and dried evenly, thereby improving the consistency and quality of the final product.
[0007] Preferably, a heating wire is fixedly installed on the inner wall of the heating tank, and a baffle is closely attached to the outer side of the heating wire. The bottom of the baffle is fixedly installed on the bottom of the inner wall of the heating tank, and multiple ventilation holes are opened inside the baffle. The heating wire can heat the PBT copolyester inside the heating tank to dehumidify it, while the baffle with ventilation holes can protect the PBT copolyester from being damaged by the heating wire.
[0008] Preferably, one end of the rotating rod has multiple connection ports, and a rotating block is rotatably installed at the bottom center of the inner wall of the heating tank. Multiple fixing rods are fixedly installed on the top of the rotating block. The outside of the fixing rods is located inside the connection ports. When the fixing rods are connected to the connection ports, the fixing rods will connect the rotating rods and the rotating block to achieve the effect of rotating together. This connection method also makes it more convenient to remove the top cover.
[0009] Preferably, a protective housing is fixedly installed on the top of the top cover, and the output end of the drive motor is fixedly installed outside the drive bevel gear through the inside of the protective housing. The outside of both the drive bevel gear and the driven bevel gear is located inside the protective housing. The protective housing located outside the drive bevel gear and the driven bevel gear can protect external impurities from entering the drive device and prevent damage to the drive device.
[0010] Preferably, a pressure relief valve is fixedly installed on the top of the top cover. The input end of the pressure relief valve is located inside the heating tank. When a large amount of air pressure accumulates inside the heating tank, the air pressure inside the heating tank is discharged through the pressure relief valve located on the top of the top cover to prevent damage to the internal structure of the heating tank.
[0011] Preferably, the bottom of the heating tank is provided with an electric valve, the valve seat of which is fixedly installed at the bottom of the heating tank, and the inlet and outlet of which are installed inside the heating tank. A filter screen is provided at the bottom of the inner wall of the heating tank to prevent PBT copolyester from overflowing. The electric valve at the bottom of the heating tank can quickly discharge the moisture generated during the drying process of PBT copolyester, preventing moisture accumulation and maintaining the effectiveness of the drying environment.
[0012] The advantages of this utility model are:
[0013] This invention addresses the problem of uneven heating of PBT copolyester during the drying process by using a drying device to dry the exterior of the PBT copolyester. The device utilizes a drive motor to rotate a driving bevel gear and a driven bevel gear, which in turn rotate a stirring blade located at the bottom. This stirring blade effectively agitates the PBT copolyester during drying, solving the problem of uneven heating caused by overly dense packing of PBT copolyester inside the drying device, which obstructs hot air circulation and moisture dissipation. This invention improves the consistency and quality of the final product. Attached Figure Description

[0021] 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 scope of protection of the present utility model.
[0022] Please see Figure 1-5As shown, a drying device for surgical gown-grade breathable PBT copolyester includes a heating tank 1. A top cover 2 is threaded onto the top of the heating tank 1. A drive motor 3 is fixedly mounted on the top of the top cover 2. A driving bevel gear 4 is fixedly mounted on the output end of the drive motor 3. A driven bevel gear 5 is externally meshed with the driving bevel gear 4. A rotating rod 6 is fixedly mounted on the bottom of the driven bevel gear 5. A driving gear 7 is fixedly mounted on the external end of one end of the rotating rod 6. A fixed gear 8 is fixedly mounted on the bottom of the driving gear 7. A first fixing block 10 is fixedly mounted on the bottom of the fixed gear 8. A fixed block 10 is rotatably mounted inside one end of a rotating rod 6. Connecting rods 12 are fixedly mounted on both sides of the first fixed block 10. A second fixed block 11 is fixedly mounted on one end of each of the connecting rods 12. A driven gear 9 is fixedly mounted on one end of each of the second fixed blocks 11, and a stirring blade 13 is fixedly mounted on the other end of each of the second fixed blocks 11. The driven gears 9 are meshed with the outside of a fixed gear 8. During operation, existing drying devices, when processing PBT copolyester, cause problems due to the excessively dense packing of PBT copolyester inside the drying device. Some parts of the PBT copolyester are blocked, affecting the circulation of hot air and the dissipation of moisture, resulting in uneven heating of the PBT copolyester. Starting the drive motor 3 rotates the driving bevel gear 4, which in turn rotates the driven bevel gear 5 meshing with it. The driven bevel gear 5 then rotates the rotating rod 6 fixed at the bottom, which in turn rotates the driving gear 7 and the fixed gear 8. The fixed gear 8 then rotates the first fixed block 10 fixed at the bottom, which in turn rotates the connecting rods 12 on both sides of its exterior. When the device is in motion, it drives the second fixed block 11 to rotate. The rotation of the second fixed block 11 drives the stirring blade 13 at the bottom to rotate. The stirring blade 13 stirs the PBT copolyester, making it more uniform during the drying process. The driven gear 9 fixedly installed on the top of the second fixed block 11 meshes with the fixed gear 8. The meshing between the driven gear 9 and the fixed gear 8 effectively transmits the power of the fixed gear 8 to the outside of the driven gear 9, ensuring that the driven gears 9 on both sides rotate simultaneously. This is crucial for applications that require uniform mixing, and can achieve a more uniform effect in the stirring process of PBT copolyester.
[0023] A heating wire 15 is fixedly installed on the inner wall of the heating tank 1. A baffle 16 is closely attached to the outer side of the heating wire 15. The bottom of the baffle 16 is fixedly installed on the bottom of the inner wall of the heating tank 1. Multiple ventilation holes are opened inside the baffle 16. During operation, when processing PBT copolyester, the existing drying device packs the PBT copolyester too densely inside the drying device, causing some parts of the PBT copolyester to be blocked, affecting the circulation of hot air and the dissipation of moisture, resulting in uneven heating of the PBT copolyester. By activating the heating wire 15, the inside of the heating tank 1 is heated, and the baffle 16 can prevent the PBT copolyester from directly contacting the heating wire 15, thus preventing damage to the PBT copolyester.
[0024] Multiple connection ports are provided inside one end of the rotating rod 6. A rotating block 17 is rotatably installed in the middle of the bottom of the inner wall of the heating tank 1. Multiple fixing rods 18 are fixedly installed on the top of the rotating block 17. The outside of the fixing rods 18 is located inside the connection port. During operation, when the existing drying device processes PBT copolyester, the PBT copolyester is too densely packed inside the drying device, causing some parts of the PBT copolyester to be blocked, affecting the circulation of hot air and the dissipation of moisture, resulting in uneven heating of the PBT copolyester. By connecting multiple fixing rods 18 to the connection port, the rotating rod 6 can be removed while rotating.
[0025] A protective shell 14 is fixedly installed on the top of the top cover 2. The output end of the drive motor 3 passes through the inside of the protective shell 14 and is fixedly installed outside the drive bevel gear 4. The exteriors of the drive bevel gear 4 and the driven bevel gear 5 are both located inside the protective shell 14. During operation, when the existing drying device processes PBT copolyester, the PBT copolyester is piled too densely inside the drying device, causing some parts of the PBT copolyester to be blocked, affecting the circulation of hot air and the dissipation of moisture, resulting in uneven heating of the PBT copolyester. The protective shell 14 provided outside the drive bevel gear 4 and the driven bevel gear 5 can prevent external impurities from entering between the drive bevel gear 4 and the driven bevel gear 5.
[0026] A pressure relief valve 19 is fixedly installed on the top of the top cover 2, and the input end of the pressure relief valve 19 is located inside the heating tank 1. During operation, when the existing drying device processes PBT copolyester, the PBT copolyester is too densely packed inside the drying device, causing some parts of the PBT copolyester to be blocked, affecting the circulation of hot air and the dissipation of moisture, resulting in uneven heating of the PBT copolyester. The pressure relief valve 19 provided on the top of the top cover 2 can release the air pressure inside the heating tank 1.
[0027] The bottom of the heating tank 1 is equipped with an electric valve 20. The valve seat of the electric valve 20 is fixedly installed at the bottom of the heating tank 1, and the inlet and outlet of the electric valve 20 are installed inside the heating tank 1. During operation, existing drying devices, when processing PBT copolyester, cause some parts of the PBT copolyester to be blocked due to the excessively dense stacking of PBT copolyester inside the drying device, which affects the circulation of hot air and the dissipation of moisture, resulting in uneven heating of the PBT copolyester. The electric valve 20 at the bottom of the heating tank 1 can more conveniently discharge the moisture generated during the drying process, thereby improving the drying efficiency of the PBT copolyester.
[0028] Working principle: When drying the exterior of PBT copolyester using a drying device, firstly, the top cover 2, which is threaded onto the heating tank 1, is opened, and the PBT copolyester is placed inside the heating tank 1. Then, the heating wire 15 is activated to heat the exterior of the PBT copolyester. The drive motor 3 is activated, driving the active bevel gear 4 to rotate. When the active bevel gear 4 rotates, it drives the driven bevel gear 5, which meshes with it externally, to rotate. When the driven bevel gear 5 rotates, it drives the rotating rod 6, which is fixedly mounted at the bottom, to rotate. The rotation of the rotating rod 6 drives the active gear 7 and the fixed gear 8 to rotate. The rotation of the fixed gear 8 drives the first fixed block 10, which is fixedly mounted at the bottom, to rotate. When block 10 rotates, it drives the connecting rods 12 on both sides of its exterior to rotate. When the connecting rods 12 rotate, they drive the second fixed block 11 to rotate. The rotation of the second fixed block 11 drives the stirring blades 13 at the bottom to rotate. The stirring blades 13 stir the PBT copolyester to make it more uniform during the drying process. The driven gear 9 fixedly installed on the top of the second fixed block 11 meshes with the fixed gear 8. The meshing between the driven gear 9 and the fixed gear 8 effectively transmits the power of the fixed gear 8 to the outside of the driven gear 9, ensuring that the driven gears 9 on both sides rotate at the same time. This is crucial for applications that require uniform mixing, and it can achieve a more uniform effect for the PBT copolyester during the stirring process.
