[0029] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0030] Embodiment 1:

[0031] like Figure 1 As shown, a drying device for yarn washing includes a dehumidification chamber 1 for dehumidifying air, and a drying chamber 2 for drying yarn. After the air is dehumidified by the dehumidification chamber 1, the moisture content in the air is greatly reduced. At this time, the dehumidified air is sent to the drying chamber 2, and the air is heated in the drying chamber 2 to dry the yarn. At this time, the air has low moisture content and high temperature, so when it flows through the yarn, the moisture in the yarn can reach the air more easily, thereby accelerating the drying efficiency of the yarn.

[0032] In order to facilitate dehumidification of air, the dehumidification chamber 1 in this solution includes a first cavity 11 and a second cavity 12, wherein the second cavity 12 is arranged around the first cavity 11. In order to facilitate the introduction of external air and send the dried air to the drying chamber 2, one end of the first cavity 11 in this solution is connected with a first air inlet pipe 13, and the other end of the first cavity 11 is connected with a first air outlet pipe 14. The end of the first air inlet pipe 13 away from the first cavity 11 is connected with a first fan 15, and the end of the first air outlet pipe 14 away from the first cavity 11 is connected to the drying chamber 2. When in use, the first fan 15 sends the filtered air from the outside to the first cavity 11 through the first air inlet pipe 13, and the air becomes dry air after dehumidification. The dry air is sent to the drying chamber 2 through the first air outlet pipe 14 to wait for use.

[0033] In order to facilitate the dehumidification of the air, this solution adopts a condensation method. To this end, a plurality of cooling fins 16 are installed on the side wall of the first cavity 11. The cooling fins 16 include a low temperature surface 17 and a high temperature surface 18. The low temperature surface 17 is thermally connected to the side wall of the first cavity 11, and a part of the high temperature surface 18 is exposed in the second cavity 12.

[0034] The cooling plate 16 in this scheme is a semiconductor cooling plate, and its working principle is: when a current passes through a thermocouple pair formed by connecting a piece of N-type semiconductor material and a piece of P-type semiconductor material, heat transfer will occur between the two ends, and the heat will be transferred from one end to the other end, thereby generating a temperature difference to form a cold and hot end. However, the semiconductor itself has resistance, and when current passes through the semiconductor, heat will be generated, which will affect heat transfer. In addition, the heat between the two plates will also be reversely transferred through the air and the semiconductor material itself. When the cold and hot ends reach a certain temperature difference and the amount of these two heat transfers is equal, an equilibrium point will be reached, and the positive and reverse heat transfers will cancel each other out. At this time, the temperature of the cold and hot ends will not continue to change. In order to achieve a lower temperature, the temperature of the hot end can be reduced by heat dissipation or other methods.

[0035] Using the above principle, the low temperature surface 17 transfers the heat in the first cavity 11 to the high temperature surface 18, and the temperature in the first cavity 11 gradually decreases. When the heat in the first cavity 11 decreases to a specified value, the first fan 15 sends the outside air into the first cavity 11. When the air flows in the first cavity 11, the moisture in the air is cooled and condensed into water droplets on the inner wall of the first cavity 11, and the air is dehumidified.

[0036] In order to ensure the cooling efficiency of the low-temperature surface 17, we need to dissipate heat from the high-temperature surface 18. To this end, a second air inlet pipe 19 is connected to one end of the second cavity 12, a second air outlet pipe 110 is connected to the other end of the second cavity 12, and a second fan 111 is connected to the end of the second air inlet pipe 19 away from the second cavity 12. When the second fan 111 is working, it will send the outside air into the second cavity 12 through the second air inlet pipe 19. Since the high-temperature surface 18 is exposed in the second cavity 12, the high-speed flowing air will exchange heat with the high-temperature surface 18, and the heated air will be discharged to the outside through the second air outlet pipe 110. At this time, the cooling work of the high-temperature surface 18 is completed, and the working efficiency of the low-temperature surface 17 is guaranteed.

[0037] This solution uses low-temperature dehumidification to dry the air, so the air is in a low-temperature state when it reaches the drying chamber 2. In order to ensure the drying efficiency of the yarn, we need to heat the air. To this end, the drying chamber 2 includes a heating chamber 21 and a material chamber 22. A heating mechanism 23 is provided in the heating chamber 21. A plurality of air outlets 24 are provided between the heating chamber 21 and the material chamber 22. One end of the air outlet 24 is connected to the heating chamber 21.

[0038] There are many options for the heating mechanism 23 in the heating chamber 21, one is a heating net composed of electric heating wires, and the other is a spiral heating pipe, in which a heating medium flows. In order to reduce the volume of the entire device and ensure heating efficiency, this solution uses electric heating to heat the low-temperature air.

[0039] After the low-temperature dry air reaches the heating chamber 21, heat exchange occurs with the heating mechanism 23, and the low-temperature air becomes high-temperature air. Then the high-temperature air enters the material chamber 22 through the air outlet to complete the drying of the yarn.

[0040] In order to facilitate the movement of the yarn in the material chamber 22, a plurality of wire wheels 25 are installed in the material chamber 22, and the plurality of wire wheels 25 are arranged along the length direction of the material chamber 22, and a wire inlet hole 26 is arranged at the bottom of the material chamber 22, and a wire outlet hole 27 is arranged at the top of the material chamber 22, and an exhaust port 28 is arranged at one end of the material chamber 22 away from the heating chamber 21, and the exhaust port 28 is covered with a sealing net 29. When in use, the yarn enters the material chamber 22 through the wire inlet hole 26, and then passes through the material chamber 22 to reach the wire outlet hole 27 with the assistance of the wire wheel 25. In this process, the air outlet 24 discharges high-temperature air toward the yarn, and the high-temperature air takes away the moisture contained in the yarn after contacting the yarn. At this time, the dry high-temperature air is transformed into humid high-temperature air. Then the humid air passes through the exhaust port 28 to the outside. Although the flying silk and dust attached to the outer wall of the yarn are greatly reduced after washing, there is still a small amount of flying silk on the outer wall. In order to prevent the air from sending these flying threads to the outside during the flow of air, causing air pollution, the air outlet 28 needs to be covered with a sealing net 29 to intercept the flying threads.

[0041] Embodiment 2:

[0042] In the above embodiment, although the yarn can be dried efficiently, when the yarn moves at a faster speed, the drying quality of the yarn will also decrease, resulting in the yarn not being completely dried. Figure 2-Figure 3 As shown, a plurality of heat-conducting columns 112 are installed in the second cavity 12, one end of the heat-conducting column 112 is connected to the high-temperature surface 18 for heat conduction, a guide wheel 113 for guiding the yarn is arranged on the side wall of the heat-conducting column 112, and the guide wheel 113 is rotatably connected to the heat-conducting column 112, a first wire feeding hole 114 is arranged at one end of the second cavity 12, and a second wire feeding hole 115 is arranged at the other end of the second cavity 12. When in use, the yarn enters the second cavity 12 through the first wire feeding hole 114, and then the yarn is sent out through the second wire feeding hole 115 with the assistance of the guide wheel 113, and then the yarn enters the material chamber 22 through the wire inlet hole 26. In this process, the heat on the high-temperature surface 18 will be transferred along the heat-conducting column 112, and part of the heat will reach the guide wheel 113. When the yarn passes through the guide wheel 113, the yarn contacts the guide wheel 113, and the two complete heat exchange, that is, the guide wheel 113 will heat the yarn, which makes the moisture contained in the yarn turn into water vapor. During this process, the second fan 111 delivers high-speed wind into the second cavity 12, and the high-speed wind takes away the water vapor during the flow, completing the pre-drying of the yarn. The moisture content of the yarn after pre-drying becomes lower, so even if the moving speed of the yarn is increased, the yarn can still be fully dried in the material chamber 22.

[0043] At the same time, the guide wheel 113 and the heat-conducting column 112 expand the heat dissipation area of ​​the high-temperature surface 18 , which enables the high-speed wind to take away the heat on the high-temperature surface 18 more quickly during the flow process, thereby accelerating the working efficiency of the low-temperature surface 17 .

[0044] It is worth noting that the guide wheel 113 in this solution needs to select a part for guiding the yarn according to customer needs.

[0045] Preferably, one end of the second air outlet pipe 110 away from the second cavity 12 is connected to a filter 116 .

[0046] Embodiment 3:

[0047] In Example 2, although the yarn drying work can be completed efficiently, its energy consumption problem is relatively serious. Figure 4-Figure 5 As shown, the second cavity 12 includes an inner cavity 117 and an outer cavity 118, the inner cavity 117 is arranged around the first cavity 11, the outer cavity 118 is arranged around the inner cavity 117, a part of the high temperature surface 18 is located in the inner cavity 117, a part of the heat-conducting column 112 passes through the inner cavity 117 to reach the outer cavity 118, the end of the first air outlet pipe 14 away from the first cavity 11 is connected to the end of the outer cavity 118, and the third air outlet pipe 119 is arranged between the end of the outer cavity 118 away from the first air outlet pipe 14 and the heating chamber 21. In order to ensure the working efficiency of the low temperature surface 17, we need to cool down the high temperature surface 18. To this end, the low temperature air after dehumidification is sent into the outer cavity 118 by the first air outlet pipe 14, and then the air will flow along the outer cavity 118 and reach the heating chamber 21 through the third air outlet pipe 119. During this process, the low-temperature air will exchange heat with the portion of the heat-conducting column 112 located in the outer cavity 118, which not only cools the high-temperature surface 18, but also preheats the low-temperature air. After the preheated air temperature is increased to a certain level, the energy required to heat the air in the heating chamber 21 will be greatly reduced.

[0048] The first wire feeding hole 114 and the second wire feeding hole 115 are respectively disposed at two ends of the inner cavity 117 .

[0049] In order to further increase the heat dissipation efficiency of the high temperature surface 18, the heat conducting column 112 is U-shaped, and a plurality of heat conducting fins 120 are installed on the side wall of the heat conducting column 112, a part of the heat conducting fins 120 is located in the inner cavity 117, and another part of the heat conducting fins 120 is located in the outer cavity 118. The heat conducting fins 120 are heat-conductingly connected to the heat conducting column 112, so the heat conducting fins 120 increase the heat dissipation area of ​​the heat conducting column 112, and the flowing air can take away the heat on the heat conducting column 112 more quickly, thereby accelerating the working efficiency of the low temperature surface 17.

[0050] In order to increase the heat exchange efficiency between the heat-conducting column 112 and the high-temperature surface 18, we need to increase the heat exchange area between the two. For this purpose, a heat-conducting shell 121 is provided between the heat-conducting column 112 and the high-temperature surface 18. A heat-conducting groove 122 is provided at one end of the heat-conducting shell 121 facing the high-temperature surface 18. The heat-conducting groove 122 covers the high-temperature surface 18, and the bottom of the heat-conducting groove 122 is heat-conductingly connected to the high-temperature surface 18. The heat-conducting column 112 is heat-conductingly connected to one end of the heat-conducting shell 121 away from the high-temperature surface 18. Among them, the middle area of ​​the U-shaped heat-conducting column 112 is connected to the heat-conducting shell 121, and the two ends of the U-shaped heat-conducting column 112 extend toward the outer cavity 118.

[0051] Preferably, a collecting chamber 123 is provided at the bottom of the first cavity 11. The collecting chamber 123 is funnel-shaped. A water outlet pipe 1240 is connected to the bottom of the collecting chamber 123. The water outlet pipe 1240 is connected to the water storage tank 124. The first fan 15 is located on one side of the water storage tank 124. The end of the first air inlet pipe 13 away from the first fan 15 passes through the collecting chamber 123 and extends into the first cavity 11. One end of the first air outlet pipe 14 is connected to the top of the first cavity 11, and the other end of the first air outlet pipe 14 is connected to the top of the outer cavity 118. In order to prevent the dehumidified air from taking out a part of the water when it is discharged through the first air outlet pipe 14, the first cavity 11 in this solution adopts the method of external air entering from the bottom and exiting from the top. When the air flows upward along the first cavity 11, the water contained in it continuously condenses into water droplets on the inner wall of the first cavity 11. The water droplets flow downward and gather under the influence of gravity, and finally reach the collecting chamber 123, and then enter the water storage tank 124 through the water outlet pipe for temporary storage. The dehumidified air is difficult to carry water droplets upward, so the dehumidification of the air is completed to the greatest extent. In order to prevent water droplets from entering the first air inlet pipe 13, the end of the first air inlet pipe 13 away from the first fan 15 needs to be slightly higher than the inner wall of the collection chamber 123.

[0052] In order to speed up the condensation of water droplets, we need to increase the contact area between the air and the inner wall of the first cavity 11 . To this end, a plurality of heat-conducting nets 125 are installed in the first cavity 11 , and the plurality of heat-conducting nets 125 are arranged along the length direction of the first cavity 11 .

[0053] Embodiment 4:

[0054] like Figure 6-7As shown, the difference between this embodiment and embodiment 3 is that the heat-conducting net 125 includes a connecting ring 126 and a cone net 127. The connecting ring 126 is arranged around the cone net 127. The connecting ring 126 is connected to the inner wall of the first cavity 11 by heat conduction. The end of the cone net 127 with a larger bottom area is connected to the connecting ring 126 by heat conduction, and the end of the cone net 127 with a smaller bottom area is arranged toward the collection cavity 123. The purpose of this design is: first, to use the connecting ring 126 and the cone net 127 to expand the thermal contact area between the inner wall of the first cavity 11 and the air, thereby accelerating the dehumidification speed of the air. Second, the water droplets condensed on the cone net 127 can be quickly gathered to form larger water droplets, and then the water droplets quickly fall to the collection cavity 123 under the influence of gravity.

[0055] In Example 3, the heat-conducting net 125 is horizontally arranged in the first cavity 11, but the heat exchange area increased by this design is limited. In this regard, the cone net in this embodiment is conical, which increases the heat exchange area to the greatest extent and accelerates the convergence speed of the condensed water droplets.

[0056] In this embodiment, an ion air knife 210 is arranged between the material chamber 22 and the heating chamber 21 . The end of the ion air knife 210 facing the heating chamber 21 is connected to the heating chamber 21 , and a plurality of air outlets are evenly arranged at the end of the ion air knife 210 away from the heating chamber 21 .

[0057] Ion air knife (also known as ion fan) static eliminator is a kind of static eliminator that transports ionized air to a distant place to eliminate static electricity. It is mainly composed of corona discharger, high voltage power supply and air supply system. It is designed and manufactured based on the principle of tip discharge and "neutralization" of positive and negative electricity. It can eliminate static electricity on insulating materials and objects. The air volume of ion fan static eliminator can be adjusted to make the destaticization space larger.

[0058] Using the above principle, high-temperature dry air carries positive and negative electrode ions to dry the yarn, which allows the yarn to be dried while the flying silk attached to the yarn due to static electricity can be fully removed.

[0059] It is worth noting that the sealing net 29 installed at the exhaust port 28 in this solution is detachable. In order to ensure ventilation, the sealing net 29 needs to be cleaned and replaced after being used for a period of time.

[0060] Preferably, a filter 116 is installed at one end of the second air outlet pipe 110 away from the second cavity 12, and the filter 116 includes a sealing shell, and an activated carbon plate is installed in the sealing shell. Since the inner cavity 117 will preheat the yarn, the high-speed air sent into the inner cavity 117 by the second fan 111 will take away some of the flying silk attached to the yarn. In order to avoid air pollution, the high-speed air will reach the filter 116 along the second air outlet pipe 110, and will be discharged after being filtered by the activated carbon plate.

[0061] In summary, the advantages of this solution are as follows: First, the moisture in the air is removed by condensation, and then the dehumidified air is heated and sent to the material chamber 22 to dry the yarn. This design speeds up the drying speed of the yarn and improves the drying quality of the yarn. Second, the heat conducting column 112 is used in conjunction with the guide wheel 113 to send the heat on the high temperature surface 18 to the guide wheel 113, and the yarn is preheated by the guide wheel 113, which speeds up the drying speed of the yarn.

[0062] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work are all within the protection scope of the present invention.
