Description

Technical Field

[0001] This invention relates to the field of drying technology, specifically to a rapid drying device for yarn bobbins with multi-dimensional hot air circulation. Background Technology

[0002] In the textile industry, yarns typically contain a certain amount of moisture after processes such as winding, dyeing, sizing, or storage. If they are not dried in a timely and uniform manner, it will not only affect the quality of subsequent processing (such as uneven tension, color difference, and mildew), but may also reduce yarn strength and yield. Therefore, drying equipment is needed to quickly dry the yarn on the yarn bobbins.

[0003] For example, patent publication number "CN115468397A", ​​entitled "A Drying Device for Cotton Yarn Spinning", includes a drying box body, a rotating mechanism, a fixed cylinder, a yarn bobbin fixing mechanism, and a dehumidifier. The rotating mechanism is located on the drying box body, the fixed cylinder is located on the rotating mechanism and inside the drying box body, the rotating mechanism is located on the fixed cylinder and inside the fixed cylinder, the yarn bobbin fixing mechanism is located on the rotating mechanism, and the dehumidifier is located on the drying box body and at the bottom end of the drying box body. The rotating mechanism includes a bracket, a reducer, a motor, a drive shaft, a limiting ring, a rotating base, and ball bearings for cotton yarn drying. The yarn bobbin fixing mechanism includes a fixed roller, a top pin, and a return spring. The fixed roller is located on a connecting shaft. The above patent belongs to the field of cotton yarn drying technology, specifically a simple-to-operate drying device for cotton yarn spinning with a small applicable range.

[0004] The aforementioned patent employs a fixed cylinder combined with a rotating yarn drum, with hot air only entering unidirectionally from one side or bottom of the chamber, resulting in a fixed airflow path. Although the rotation of the yarn drum can change the airflow surface, it is difficult for the hot air to penetrate both axially and radially simultaneously, leading to dead airflow zones inside the stacked yarn drums and in the central area, resulting in uneven drying and low efficiency. Furthermore, the hot air is cooled and humidified after flowing through the upstream yarn drum, causing the downstream area to have lower temperatures and higher humidity. The dehumidification device is only located at the bottom of the chamber, treating only the final humid and hot exhaust gas, failing to separate moisture in real time during the drying process and utilize waste heat in stages. This results in a large amount of sensible heat being discharged with the exhaust gas at once, causing serious energy waste and increasing the burden on subsequent dehumidification. Therefore, a rapid yarn drum drying device with multi-dimensional hot air circulation was invented. Summary of the Invention

[0005] The purpose of this invention is to provide a yarn bobbin rapid drying device with multi-dimensional hot air circulation to solve the problems mentioned in the background art.

A rotating component for controlling the rotation of the placement frame is installed between the placement frame and the cylinder.

[0021] The rotating assembly includes a first gear ring, the inner wall of which is fixed to the outer wall of the cylinder, and a first gear for meshing with the outer wall of the first gear ring is fixedly connected to the bottom end of the placement frame.

[0022] Furthermore, the power unit includes a No. 1 motor, which is fixedly installed at the top of the tank. The output end of the No. 1 motor is fixedly connected to a transmission frame. The outer wall of the transmission frame is rotatably connected to the inner wall of the tank. The inner wall of the transmission frame is fixed to the outer wall of the rotating frame. The inner wall of the transmission frame is fixedly connected to guide vanes.

[0023] Furthermore, the inner wall of the partition plate is rotatably connected to the outer wall of the cylinder, the outer wall of the partition plate is fixed to the inner wall of the transmission frame, and a rotating door is rotatably connected to the outer wall of the tank.

[0024] Furthermore, the exhaust device includes an exhaust ring, the interior of which is rotatably connected to the outer wall of the cylinder, the top end of which is fixed to the top end of the rotating frame, an annular groove on the outer wall of the partition plate, a guide pipe fixedly connected between the annular groove and the exhaust ring, an intake ring fixedly connected to the outer wall of the tank, an exhaust hole on the outer wall of the tank for communicating with the interior of the annular groove and the interior of the intake ring, and a sealing ring fixedly connected to the outer wall of the transmission frame for ensuring communication between the interior of the annular groove and the interior of the intake ring.

[0025] Furthermore, the gas control device includes an air inlet ring, the inner wall of which is fixed to the outer wall of the tank, and the outer wall of the tank is provided with an air filling hole for communicating with the inside of the air inlet ring and the inside of the tank.

[0026] Furthermore, the negative pressure device includes an air pump, the air outlet pipe of the tank is fixedly connected to the air pump, and a recovery component is installed at the air outlet end of the air pump.

[0027] Furthermore, the recovery assembly includes a regulating diversion pipe, the air inlet end of which is fixed to the air outlet end of the air pump. A cylindrical component is fixedly connected to the first air outlet end of the regulating diversion pipe. The air inlet end of the cylindrical component is connected to the air outlet end of the air pump through the regulating diversion pipe.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] This rapid yarn drying equipment with multi-dimensional hot air circulation integrates a swirling dehumidification structure inside the tank. By introducing airflow tangentially to form a strong vortex field, water vapor molecules migrate towards the central low-temperature zone and condense into droplets under the combined action of centrifugal force and radial temperature gradient. This achieves a pre-dehumidification mechanism that completes moisture separation in the middle of the drying process, preventing hot and humid gas from continuing to flow to the downstream area and causing temperature drop and humidity accumulation. This ensures the drying quality and environmental stability of the yarn in the downstream area.

[0030] Meanwhile, by setting up a multi-dimensional hot air circulation structure with the coordinated operation of guide vanes, air inlet ring and rotating frame, hot air can dynamically penetrate the gap between the yarn bobbins in both the axial and radial directions. Combined with the rotational motion of the placement frame during its revolution due to its engagement with the fixed toothed ring, the yarn bobbins are heated in all directions in three-dimensional space. This effectively eliminates the problems of internal dead corners and uneven drying in stacked areas caused by traditional unidirectional airflow, and significantly improves drying uniformity and efficiency.

[0031] By setting up partitions inside the tank, the drying space is divided into multiple independent but interconnected drying zones along the airflow direction. This allows the hot air to release heat step by step and be utilized in stages as it flows from top to bottom. This avoids the problem of insufficient downstream drying caused by the rapid cooling and humidification of hot air after it penetrates all the yarn bobbins at once in the traditional single-cavity structure. The partitions, together with the multi-dimensional hot air circulation and dehumidification structure, enable each zone to maintain a relatively stable temperature and humidity environment. This not only improves the overall drying uniformity but also provides a structural basis for "pre-dehumidification" and end-of-pipe hot air reuse. Attached Figure Description

[0057] The rotating assembly includes a first gear ring 304, the inner wall of which is fixed to the outer wall of the cylinder 301, and a first gear 305 for meshing with the outer wall of the first gear ring 304 is fixedly connected to the bottom end of the placement frame 303.

[0058] The power unit 6 includes a first motor 601, which is fixedly installed on the top of the tank 1. The output end of the first motor 601 is fixedly connected to a transmission frame 602. The outer wall of the transmission frame 602 is rotatably connected to the inner wall of the tank 1. The inner wall of the transmission frame 602 is fixed to the outer wall of the rotating frame 302. A guide vane 603 is fixedly connected to the inner wall of the transmission frame 602.

[0059] The inner wall of the partition plate 7 is rotatably connected to the outer wall of the cylinder 301, the outer wall of the partition plate 7 is fixed to the inner wall of the transmission frame 602, and the outer wall of the tank body 1 is rotatably connected to the door 10.

[0060] The exhaust device includes an exhaust ring 205, the interior of which is rotatably connected to the outer wall of the cylinder 301. The top end of the exhaust ring 205 is fixed to the top end of the rotating frame 302. The outer wall of the partition plate 7 is provided with an annular groove 206. A guide pipe 207 is fixedly connected between the annular groove 206 and the exhaust ring 205. An intake ring 208 is fixedly connected to the outer wall of the tank body 1. An exhaust hole is provided on the outer wall of the tank body 1 to enable communication between the interior of the annular groove 206 and the interior of the intake ring 208. A sealing ring 604 is fixedly connected to the outer wall of the transmission frame 602 to ensure communication between the interior of the annular groove 206 and the interior of the intake ring 208.

[0061] The gas control device 4 includes an air inlet ring 401, the inner wall of which is fixed to the outer wall of the tank 1, and an air filling hole is provided on the outer wall of the tank 1 to enable communication between the inside of the air inlet ring 401 and the inside of the tank 1.

[0062] The negative pressure device includes an air pump 8, the air outlet pipe of the tank 1 is fixedly connected to the air pump 8, and the air outlet end of the air pump 8 is equipped with a recovery component 9.

[0063] The recovery component 9 includes a regulating diversion pipe 902, the air inlet end of the regulating diversion pipe 902 and the air outlet end of the air pump 8 are fixed together, a cylinder 901 is fixedly connected to the first air outlet end of the regulating diversion pipe 902, the air inlet end of the cylinder 901 is connected to the air outlet end of the air pump 8 through the regulating diversion pipe 902, a capillary guide plate 903 is slidably connected to the inner wall of the cylinder 901, a first telescopic component 904 for controlling the movement of the capillary guide plate 903 is installed between the inside of the cylinder 901 and the capillary guide plate 903, a circulating air dehumidification device is fixedly connected to one end of the cylinder 901, and the air outlet end of the cylinder 901 is fixed to the air inlet ring 401.

[0064] The staff opens the rotating door 10 and places the yarn bobbins to be dried on the placement rack 303. The staff applies force to the transmission frame 602, causing the transmission frame 602 and the rotating frame 302 to rotate, thereby achieving full placement on the placement rack 303. After placement is completed, the rotating door 10 is closed and the drying device is started to dry the yarn bobbins. After the rotating door 10 is closed, it can be regarded as the tank 1, and the suction ring 208 and the air inlet ring 401 installed on the tank 1 are both installed on the rotating door 10.

[0065] The outer wall of the drying equipment is connected to an air supply device and a recovery device. The air supply device continuously supplies hot air to the air control device 4. The recovery device recovers the gas that passes through the tank 1 and participates in the drying process. The hot and humid gas discharged from the tank 1 is pre-cooled and heat is recovered by a total heat exchanger. Then it enters the condensation module for dehumidification. After the moisture is precipitated, the dry gas is reheated in the total heat exchanger and transported to the air supply device through an insulated flow channel. The whole process minimizes heat loss and realizes the recycling of the dried gas.

[0066] like Figure 3 and Figure 4 As shown, the partition plate 7 divides the interior of the tank 1 into several spaces. The air intake ring 401 continuously supplies hot air to each space. The spaces are arranged vertically from top to bottom, resulting in space number one, space number two, and space number three. The air intake ring 401 continuously supplies hot air to space number one through the tank 1. The output end of motor number one 601 rotates, causing the transmission frame 602 and guide vanes 603 to rotate. The guide vanes 603 guide the hot air. Since the air intake ring 401 is fixedly connected to the top of the tank 1, both the top air intake ring 401 and the air intake ring 401 located on the outer wall supply air simultaneously, thus achieving axial and radial flow. The rotation of the guide vanes 603, in turn, affects the axial flow. The radial hot air is guided to direct the airflow and dry the yarn bobbins on the placement rack 303 in a high-temperature environment. By setting a partition plate 7 inside the tank 1, the drying space is divided into multiple independent but connected drying areas along the airflow direction. This allows the hot air to release heat step by step and be utilized in stages as it flows from top to bottom. This avoids the problem of insufficient downstream drying caused by the rapid cooling and humidification after the hot air penetrates all the yarn bobbins at once in the traditional single-cavity structure. The partition plate 7, together with the multi-dimensional hot air circulation and dehumidification structure 2, can maintain a relatively stable temperature and humidity environment in each area, which not only improves the overall drying uniformity, but also provides a structural basis for "pre-dehumidification" and end-of-line hot air reuse.

[0067] Simultaneously, the transmission frame 602 causes the rotating frame 302 and the placement frame 303 to rotate. During the rotation of the placement frame 303, the first gear 305 and the fixed first gear ring 304 rotate, which in turn causes the first gear 305 to rotate, thereby causing the placement frame 303 and the yarn bobbins mounted on the placement frame 303 to rotate. This causes the yarn bobbins originally located in the central area to rotate to the outer area, thus ensuring uniform drying of the yarn bobbins within the first space. By setting up a multi-dimensional hot air circulation structure in which the guide vanes 603, the air inlet ring 401 and the rotating frame 302 work together, hot air can dynamically penetrate the gap between the yarn bobbins in both the axial and radial directions. Combined with the rotational motion of the placement frame 303 during its revolution due to meshing with the fixed gear ring, the yarn bobbins are heated in all directions in three-dimensional space. This effectively eliminates the problems of internal dead corners and uneven drying in stacked areas caused by traditional unidirectional airflow, significantly improving drying uniformity and efficiency.

[0068] The air pump 8 starts, creating a negative pressure at the outlet of tank 1. As hot air is continuously introduced into the interior of space one, it enters the area of ​​the dehumidification structure 2 through the air inlet on cylinder 301. The hot air is guided by the first vortex component 203. The dehumidification structure 2 adopts a tangential air inlet vortex cavity design. Its core function is to induce a humidity and temperature gradient in the radial direction of the humid air through the first vortex channel 202, and to use condensation phase change and airflow organization to preferentially discharge high-humidity components, thereby achieving dehumidification without relying on external refrigeration and high-pressure air sources. Under these conditions, efficient and low-energy "pre-dehumidification" is achieved. Its working principle and verifiable basis are as follows: A swirling flow field is formed in the hot air within the first vortex channel 202, creating a central low-temperature zone (at which point a temperature gradient is established). Driven by the hot air in the first space, the humid and hot air enters the first vortex channel 202 at a speed of 15–25 m / s through the tangential inlet, forming a strong rotating flow. Due to gas viscosity dissipation and angular momentum redistribution, the pressure and temperature in the central axis region decrease, while the outer wall region maintains a higher temperature due to frictional heating, thus achieving efficient and low-energy "pre-dehumidification." A stable internal and external temperature gradient is formed radially. Water vapor molecules are smaller than the average molecular weight of dry air. Under centrifugal force, air tends to approach the outer wall region of the first vortex channel 202. Furthermore, driven by thermophoretic force, water vapor molecules migrate from the high-temperature outer region to the low-temperature central axis, resulting in a higher water vapor mole fraction in the central region compared to the periphery, forming humidity stratification. When the temperature in the central region is lower than the dew point temperature of the moist air (the dew point is determined by the temperature and humidity inside the drying chamber, e.g., 85℃ / 85%RH → dew point ≈ 82℃), the enriched water vapor... Local condensation of the gas generates a large number of micron-sized droplets (typically 1–3 μm in diameter). The droplet diameter generated by condensation is usually less than 5 μm. Under these conditions, the droplet motion is mainly dominated by the gas drag force and closely follows the airflow trajectory. Since the center of the swirling flow field is a low-pressure reflux zone and the airflow direction is towards the central exhaust port, i.e., the No. 1 exhaust pipe 204, the tiny droplets are stably carried to the No. 1 exhaust pipe 204 and discharged from the tank 1, without migrating to the outer wall due to centrifugal force. Furthermore, the exhaust structure 2 is located in a high-temperature environment inside the tank 1, thereby reducing the generation of large droplets.

[0069] When the droplet size is less than 8 micrometers, in a typical drying swirling field, its motion is mainly dominated by the airflow drag force, almost completely following the airflow trajectory. Centrifugal sedimentation is negligible. Only larger droplets (greater than 10 micrometers) will be significantly affected by centrifugal force and migrate outward. For example, droplets formed by condensation are less than or equal to 3 μm and will not be thrown to the outer layer. Most small droplets will be discharged with the central airflow. By controlling the air pressure, the speed at which the gas enters the internal dehumidification structure 2 is increased, thereby shortening the residence time of the gas in the internal dehumidification structure 2. This reduces the generation of large droplets and ensures early dehumidification. Through the integrated swirling dehumidification structure 2 inside the tank 1, a strong vortex field is formed by tangentially introducing airflow. Under the combined action of centrifugal force and radial temperature gradient, water vapor molecules migrate to the central low-temperature zone and condense into droplets. This achieves the "early dehumidification" mechanism of completing moisture separation in the middle of the drying process, avoiding the continued flow of hot and humid gas to the downstream area, which causes temperature drop and humidity accumulation, thereby ensuring the drying quality and environmental stability of the downstream area.

[0070] Water vapor migrates from the high-temperature outer region to the low-temperature central axis due to the thermophoretic effect. When the temperature in the central region is lower than the dew point of the humid air, the water vapor undergoes local condensation, forming micron-sized droplets, which are then directionally discharged with the central airflow, thus achieving early dehumidification. This process is not a simple gas-gas separation, but rather the result of the synergistic effect of thermophoretic migration and condensation phase change.

[0071] Due to the continuous rotation of the motion device 3, the moisture in the first exhaust pipe 204 needs to be quickly discharged to reduce the impact of moisture on the inside of the tank 1. The exhaust port is connected to a negative pressure device to form a negative pressure, thereby ensuring the rapid movement of moisture. The moisture moves from the first exhaust pipe 204 to the exhaust ring 205, and is sucked out by the negative pressure device through the air guide pipe 207, the annular groove 206 and the suction ring 208. Note that the negative pressure maintained by the negative pressure device is small and will not affect the swirling field in the dehumidification structure 2. At the same time, the sealing ring 604 set on the transmission frame 602 can ensure the communication between the inside of the annular groove 206 and the suction ring 208. The inner wall of the sealing ring 604 is rotatably connected to the outer wall of the partition plate 7, and the outer wall of the sealing ring 604 is rotatably connected to the inside of the tank 1. The rotation of the sealing ring 604 will not affect the communication between the inside of the annular groove 206 and the suction ring 208.

[0072] The dehumidification structure 2 can remove most of the moisture in the hot air, but it cannot completely remove moisture. The hot air passing through the dehumidification structure 2 will flow into the second space through the air outlet on the pipe and the cylinder 301. At this time, the air inlet ring 401 will also continuously introduce hot air into the second space. Combined with the rotation of the guide vane 603 and the rotation of the placement frame 303, the yarn bobbin in the second space will be completely dried. At the same time, the hot and humid air in the second space will be moved to the third space through the dehumidification structure 2. Following the above steps, the yarn bobbin in the third space will be completely dried.

[0073] The shock-absorbing pad 5 is fixedly installed inside the cylinder 301 and on the outer wall of the first pipe fitting 201. At the same time, the shock-absorbing pad 5 is provided with vent holes to ensure communication between the dehumidification structure 2 and the inside of the tank 1, thereby ensuring the passage of airflow. Since the moving device 3 will vibrate under the drive of the first motor 601, the shock-absorbing pad 5 is provided to ensure the stability of the swirling flow field inside the dehumidification structure 2 and reduce the impact of the moving device 3 on the dehumidification structure 2. At the same time, the bottom end of the first pipe fitting 201 is fixedly installed inside the bottom end of the tank 1 through the shock-absorbing pad 5.

[0074] In the terminal space, such as space number three, the fresh air introduced to achieve uniform drying of the yarn tube inside tank 1 (entering the interior of tank 1 through air inlet ring 401) will quickly mix with the original terminal air flowing to the end inside tank 1 to obtain a mixed gas. Because the residence time of this mixed gas is extremely short, it is drawn away before it has fully participated in the drying process. If the heat is recovered by the recovery device, the limited heat exchange efficiency will result in a large amount of heat energy being wasted, which will increase the power consumption of the fan and the complexity of the system. The mixed gas must be discharged in time to maintain the airflow and pressure balance inside tank 1. However, because its residence time in the cavity is extremely short, a recovery component 9 is provided.

[0075] Air pump 8 starts, ensuring negative pressure at the outlet of tank 1. Air pump 8 guides the mixed gas in space 3 to recovery component 9. The diversion pipe 902 controls the mixed gas, moving it into the interior of cylinder 901. The telescopic end of telescopic component 904 moves. Telescopic component 904 can be electrically, hydraulically, or pneumatically operated. The volume of the mixed gas inside cylinder 901 changes, inducing spontaneous condensation of water vapor. Capillary guide plate 903, with its internal capillary pores, can drain condensate. The circulating dehumidification device continuously supplies hot air to one side of capillary guide plate 903, causing water on that side to vaporize. This allows capillary guide plate 903 to continuously absorb water, which is then discharged through the circulating dehumidification device. Simultaneously... The system can dehumidify hot air. After the recovery component 9 has been running for a set time, the telescopic end of the first telescopic component 904 extends, thereby introducing the mixed gas inside the cylinder 901 into the air intake ring 401, preferentially into the air intake ring 401 of the third space. At the same time, when the mixed gas is introduced into the air intake ring 401, the control pipe 902 adjusts the internal control valve, so that the airflow will flow out through the second outlet of the control pipe 902. The second outlet is connected to the total heat exchanger until the mixed gas inside the cylinder is completely discharged. Then, the control pipe 902 is adjusted to allow the first outlet to discharge air, and the above cycle is repeated. By setting the recovery component 9 at the end of the tank 1, the mixed air that was originally discharged with a short residence time and had not fully participated in drying is introduced into the controllable circulation channel. After simple diversion and short retention, it is directly reinjected into the upstream drying area using its own waste heat, avoiding the energy waste of hot air entering at the end.
