Description

Technical Field

[0001] This utility model relates to the field of cooling technology in chemical fiber production, specifically a cooling device for chemical fiber production and molding. Background Technology

[0002] Chemical fibers are textile-grade fibers made from natural or synthetic polymers as raw materials, through processes such as preparing spinning solutions, spinning, and post-processing. The manufacturing of chemical fibers can be summarized into four steps: raw material preparation; synthesis (polymerization) of polymers or chemical, physical, and mechanical processing of natural polymers; preparation of spinning melt or spinning solution; spinning of chemical fibers; and post-processing of chemical fibers, often requiring cooling during the spinning process.

[0003] A Chinese patent (publication number: CN218711065U) discloses a cooling device for chemical fiber production and forming, including a spinning forming box, a first support column, and a bracket. A water tank is placed on one side of the outer surface of the spinning forming box, and second support columns are fixedly connected to both sides of the upper surface of the water tank. A drying chamber is fixedly connected to one end of the second support column. Several drying plates are installed inside the drying chamber. By activating the water pump in the cooling assembly, the cold water inside the water tank can continuously circulate inside the condenser tube, thereby effectively reducing the temperature of the air inside the cooling chamber. Then, in conjunction with the several drying plates installed inside the drying chamber, layer-by-layer filtration is performed, thereby effectively absorbing the moisture contained in the air, and thus obtaining dry cold air. This improves the cooling effect inside the spinning forming box while effectively preventing moisture in the air from adsorbing onto the surface of the chemical fiber.

[0004] During use, the aforementioned equipment filters out humid air through its drying plate, effectively absorbing moisture and keeping the cool air blown into the spinning box dry. This prevents moisture from adsorbing onto the surface of the synthetic fibers. However, over time, the drying plate may become unusable due to excessive moisture buildup, requiring periodic replacement. Manual replacement is time-consuming and disrupts the equipment's operation.

[0005] To address this issue, we designed a cooling device for chemical fiber production and molding. Utility Model Content

[0006] The purpose of this invention is to provide a cooling device for the production and molding of chemical fibers, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a cooling device for chemical fiber production and forming, including a mounting box, two drying plates slidably connected inside the mounting box, a fixed box connected to the top of the mounting box, a drive gear rotatably connected inside the fixed box, two symmetrical transmission racks meshing on the drive gear, the opposite sides of the two transmission racks being respectively connected to the two drying plates, and a self-locking motor driving the drive gear to rotate is connected to one side of the fixed box.

[0008] When the drive gear rotates, it drives the two drying plates to slide in opposite directions. A cooling structure is provided on one side of the mounting box.

[0009] Furthermore, the cooling structure includes a vortex tube connected to one side of the mounting box, wherein,

[0010] The vortex tube has a cold air outlet and a hot air outlet at its two ends, respectively, and the cold air outlet is connected to the air inlet of the mounting box.

[0011] Furthermore, the hot air outlet is connected to a connecting pipe, and the other end of the connecting pipe is connected to an exhaust fan. The air outlet of the exhaust fan is connected to the fixed box for drying the drying plate.

[0014] Furthermore, the mounting box is connected to a flow guide seat and two mutually symmetrical flow guide plates, and the flow guide seat, flow guide plates and drying plate are distributed sequentially along the air intake direction of the mounting box.

[0015] Furthermore, the end of the mounting box away from the vortex tube is connected to a mounting joint, and the mounting joint has an integrally formed external thread groove.

[0016] Furthermore, a workbench is connected to the bottom of the mounting box.

[0017] Compared with existing technologies, the advantages of this invention are as follows: Compressed air enters the vortex tube and is separated into cold and hot airflows, with the cold air entering the mounting box. The guide seat and guide plate guide the airflow, improving the dehumidification efficiency of the drying plates and ensuring full contact between all parts and the airflow. A self-locking motor drives the drive gear, which in turn drives the transmission rack to make the two drying plates slide in opposite directions.

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a cooling device for chemical fiber production and forming, including a mounting box 1, two drying plates 2 slidably connected inside the mounting box 1, a fixed box 10 connected to the top of the mounting box 1, a drive gear 3 rotatably connected inside the fixed box 10, and two symmetrical transmission racks 4 meshing on the drive gear 3. The opposite sides of the two transmission racks 4 are respectively connected to the two drying plates 2.

[0026] When the drive gear 3 rotates, it drives the two drying plates 2 to slide in opposite directions. A cooling structure is provided on one side of the mounting box 1.

[0027] In practice, the self-locking motor 7 on one side of the fixed box 10 drives the drive gear 3 to rotate. The drive gear 3 meshes with two symmetrical transmission racks 4, with the opposite sides of the transmission racks 4 connected to two drying plates 2 respectively. When the self-locking motor 7 drives the drive gear 3 to rotate, the two transmission racks 4 will cause the two drying plates 2 to slide in opposite directions. The cooling structure on one side of the mounting box 1 can cool the air entering the mounting box 1. When one drying plate 2 is saturated with moisture, it can be switched to another drying plate 2, reducing equipment downtime and improving production efficiency.

[0028] See Figure 1-4 The cooling structure includes a vortex tube 5 connected to one side of the mounting box 1, wherein...

[0029] The two ends of the vortex tube 5 are respectively provided with a cold air outlet and a hot air outlet, and the cold air outlet is connected to the air inlet of the mounting box 1.

[0030] It should be noted that in vortex tube 5, high-pressure gas enters the vortex chamber tangentially through a nozzle, forming a high-speed rotating vortex. Due to the inertia of gas molecules, a pressure gradient is generated along the inner diameter of the vortex chamber, with lower pressure in the central region and higher pressure in the peripheral region. Under the action of this pressure difference, part of the gas moves towards the center and is discharged from the cold gas pipe, forming a low-temperature airflow; the other part of the gas is discharged from the hot gas pipe along the wall of the vortex chamber, forming a high-temperature airflow, thus achieving the separation of cold and hot airflows.

[0031] In practice, when compressed air enters the vortex tube 5, it forms a vortex inside, thus separating the air into two streams: a cold air stream and a hot air stream. The cold air outlet of the vortex tube 5 is connected to the air inlet of the mounting box 1, allowing cold air to enter the mounting box 1.

[0032] See Figure 1-4 The hot air outlet is connected to a connecting pipe 12, and the other end of the connecting pipe 12 is connected to an exhaust fan 6. The air outlet of the exhaust fan 6 is connected to the fixed box 10 for drying the drying plate 2.

[0033] In practice, when the exhaust fan 6 is working, it will introduce the hot air generated by the vortex tube 5 into the fixed box 10 to dry the drying plate 2 that slides into the fixed box 10, thus realizing the automatic drying and regeneration of the drying plate 2. The dried drying plate 2 can be reused, improving the utilization rate of the drying plate 2. At the same time, the hot air generated by the vortex tube 5 is used to realize the recovery and utilization of energy, thus improving energy efficiency.

[0034] See Figure 1-4 The top of the mounting box 1 is connected to a compressor 11, and the air outlet of the compressor 11 is connected to the air inlet of the vortex tube 5 through the mounting pipe.

[0035] In practice, the compressor 11 at the top of the mounting box 1 delivers high-pressure air through the mounting pipe to the air inlet of the vortex tube 5, providing continuous and stable compressed air to the vortex tube 5 and ensuring its normal operation.

[0036] See Figure 1-4 A guide block 8 is connected to one side of the transmission rack 4. The guide block 8 is slidably connected inside the fixed box 10. The fixed box 10 has a groove inside that matches the guide block 8.

[0037] In practice, when the drive gear 3 drives the transmission rack 4 to move, the guide block 8 moves along the slide groove to provide guidance for the transmission rack 4, ensuring the stability of the movement of the transmission rack 4, and thus ensuring that the drying plate 2 can slide smoothly and accurately.

[0038] See Figure 1-4 The installation box 1 is connected to a flow guide seat 13 and two symmetrical flow guide plates 14. The flow guide seat 13, flow guide plates 14 and drying plate 2 are distributed in sequence along the air intake direction of the installation box 1.

[0039] In practice, when cold air enters the mounting box 1 from the vortex tube 5, the guide seat 13 and the guide plate 14 guide and divert the airflow, so that the airflow passes through the drying plate 2 more evenly, which improves the dehumidification efficiency of the drying plate 2 and ensures that all parts of the drying plate 2 can fully contact the airflow.

[0040] See Figure 1-4 The end of the mounting box 1 away from the vortex tube 5 is connected to the mounting connector 9, which has an integrally formed external thread groove.

[0041] In practice, the external threaded groove can be used to make a threaded connection with the chemical fiber production and molding equipment.

[0042] See Figure 1-4 The bottom of the installation box 1 is connected to a workbench.

[0043] In practice, the workbench connected to the bottom of the mounting box 1 provides stable support for the entire cooling equipment, allowing the equipment to be placed stably on the production workshop floor, which facilitates the installation of the equipment.

[0044] Working principle: Before use, when compressed air enters the vortex tube 5, it will form a vortex inside, thereby separating the air into two airflows: cold and hot. The cold air outlet of the vortex tube 5 is connected to the air inlet of the mounting box 1, allowing cold air to enter the mounting box 1;

[0045] When cold air enters the mounting box 1 from the vortex tube 5, the guide seat 13 and guide plate 14 guide and divide the airflow, making the airflow pass through the drying plate 2 more evenly, improving the dehumidification efficiency of the drying plate 2, and ensuring that all parts of the drying plate 2 can fully contact the airflow. The self-locking motor 7 on one side of the fixed box 10 can drive the drive gear 3 to rotate. The drive gear 3 meshes with two mutually symmetrical transmission racks 4, and the opposite sides of the transmission racks 4 are connected to the two drying plates 2 respectively. When the self-locking motor 7 drives the drive gear 3 to rotate, the two transmission racks 4 will drive the two drying plates 2 to slide in opposite directions. The cooling structure on one side of the mounting box 1 can cool the air entering the mounting box 1. When one drying plate 2 is saturated with moisture, it can be switched to another drying plate 2, reducing equipment downtime and improving production efficiency.

[0046] When the exhaust fan 6 is working, it introduces the hot air generated by the vortex tube 5 into the fixed box 10 to dry the drying plate 2 that slides into the fixed box 10, realizing the automatic drying and regeneration of the drying plate 2. The dried drying plate 2 can be reused, improving the utilization rate of the drying plate 2. At the same time, the hot air generated by the vortex tube 5 is used to realize energy recovery and utilization, improving energy efficiency.
