Description

Technical Field

[0001] This invention relates to the field of textile drying equipment technology, and more specifically, to a drying equipment for textile fabric production. Background Technology

[0002] In the textile production process, drying is a crucial step, directly affecting the quality of the fabric, the efficiency of subsequent processing, and the stability of the finished product's performance. When textile fabrics containing moisture are not dried sufficiently and evenly, they are prone to mold growth, leading to discoloration or unpleasant odors. Furthermore, dimensional deviations may occur in subsequent cutting, dyeing, and other processing stages, severely impacting the quality of the final product.

[0003] Currently, most drying equipment widely used in the textile industry heats and dries fabrics using drying drums. A typical structure of this type of equipment consists of multiple drying drums installed at certain intervals on a frame, with the textile fabric wrapped around the surface of each drum in sequence. During drying, heat is generated by a heat source inside the drum (such as steam or electric heating), which is then transferred to the drum wall and further heats the fabric in contact with the drum wall, causing the moisture in the fabric to evaporate, thus achieving the drying effect.

[0004] However, traditional drying equipment has certain limitations in practical applications. Traditional equipment typically arranges multiple drying drums densely, but because the fabric is dried continuously, the steam generated during the drying process re-adheres to the upper layers of the fabric. This causes the fabric's humidity to rise slightly after the initial drying, thus slowing down the drying speed. Increasing the distance between the drying drums to avoid this problem, however, results in a temperature drop in the fabric suspended between adjacent drums due to the slower drum rotation. This leads to repeated heating and cooling of the fabric, which is extremely detrimental to the overall structure of the fabric. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a drying device for textile fabric production, which solves the technical problem in the prior art where the fabric humidity rises or experiences repeated temperature changes due to the spacing between drying cylinders in traditional drying equipment.

[0006] According to one aspect, at least one embodiment of the present invention provides a drying apparatus for textile fabric production, used for drying textile fabrics containing moisture, comprising:

[0007] frame;

[0008] The drying cylinders are a plurality of drying cylinders, which are spaced apart on the frame. The drying cylinders are used to dry textile fabrics by winding them around the fabrics.

[0009] A bracket is detachably mounted on the drying cylinder. An external heating plate is mounted on the bracket, and a heating coil is installed inside the external heating plate. The heating coil is connected to the inside of the drying cylinder, allowing hot air from the drying cylinder to enter the heating coil. The external heating plate is used to contact the textile fabric between two adjacent drying cylinders to heat and dry the textile fabric.

[0010] Optionally, the drying cylinder has an air inlet for introducing hot air and an air outlet for discharging hot air, the drying cylinder comprising:

[0011] Heat-conducting cylinder;

[0012] A fixed end cap is fixedly disposed at one end of the heat-conducting cylinder. The fixed end cap is used to close one end of the heat-conducting cylinder. The fixed end cap has a first shaft tube that is rotatably connected to the frame. The exhaust port is opened on the first shaft tube.

[0013] A movable end cap is detachably disposed at the other end of the heat-conducting cylinder. The movable end cap slides in fit with the outer peripheral wall of the end of the heat-conducting cylinder. The end of the movable end cap away from the heat-conducting cylinder is fixedly connected to the frame. The movable end cap is used to close the other end of the heat-conducting cylinder. The air inlet is opened on the second shaft tube of the movable end cap.

[0014] Optionally, the support includes:

[0015] The heat-conducting cylinder has two side rods, which are respectively disposed at both ends of the heat-conducting cylinder. One end of one side rod is rotatably connected to the first shaft tube, and the other end is hinged to the external heating plate. One end of the other side rod is fixedly connected to the movable end cover, and the other end is hinged to the external heating plate. The external heating plate is located between the two side rods, and the extension direction of the external heating plate is parallel to the axial direction of the heat-conducting cylinder. The external heating plate can swing relative to the support to contact the surface of the textile fabric.

[0016] Optionally, a correction plate is provided at one end of the side rod frame away from the heat-conducting cylinder. The correction plates on both side rod frames extend outward from the external heating plate and are used to limit the two sides of the textile fabric to correct the textile fabric.

[0017] Optionally, the external heating plate includes:

[0018] A strip-shaped base, wherein one side wall of the strip-shaped base has an installation space, and the heating coil is disposed within the installation space;

[0019] A cover plate is detachably mounted on the strip base and covers the opening of the installation space. The cover plate is provided with a number of heat dissipation holes at intervals. The cover plate is used to contact the textile fabric and to transfer the heat of the heating coil to the textile fabric through the heat dissipation holes.

[0020] Optional, also includes:

[0021] An annular nozzle is fixedly installed inside the movable end cover and is arranged concentrically with the movable end cover. The annular nozzle is provided with a plurality of air nozzles arranged at circumferential intervals.

[0022] A turntable is rotatably mounted inside the movable end cover. The turntable has several fan blades arranged in a circle. The jet nozzle is used to spray airflow onto the fan blades to drive the fan blades and the turntable to rotate synchronously.

[0023] Optionally, an air passage is provided in the middle of the turntable, the air passage is connected to the air inlet, and a baffle is provided in the air passage to disturb the hot air entering the heat-conducting cylinder.

[0024] Optionally, the annular nozzle includes:

[0025] An annular air guide tube is fixedly mounted on the movable end cap, and the air nozzle is mounted on the annular air guide tube;

[0026] An air inlet pipe is connected at one end to the annular air guide pipe and at the other end to the air passage. The air inlet pipe is used to send some of the hot air in the air passage into the annular air guide pipe.

[0027] A flow divider is disposed within the air passage. The air inlet pipe is connected to the flow divider. The flow divider has an opening facing the air inlet. The flow divider and the inner wall of the air passage can form an air storage cavity for supplying air to the air inlet pipe. The flow divider is used to receive the airflow from the air inlet and allow the airflow to enter the air inlet pipe.

[0028] Optional, also includes:

[0029] A hot air input pipe is connected to the movable end cap and communicates with the air inlet;

[0030] The three-way valve has a first port connected to the inlet end of the hot gas input pipe, a second port connected to an external hot gas source, and a third port connected to the exhaust end of the heating coil via a hose. The three-way valve can deliver hot gas from the heating coil and hot gas from the hot gas source to the hot gas input pipe.

[0031] Optionally, both the cover plate and the outer wall of the strip seat can be detachably provided with a moisture-absorbing sponge layer.

[0032] The beneficial effects of this invention are as follows:

[0033] In this invention, on the one hand, the fabric between adjacent drying drums is heated by an external heating plate, effectively preventing the fabric temperature from dropping during transport and avoiding repeated heating and cooling, thus protecting the overall structure of the textile fabric. On the other hand, since the heating coil is connected to the inside of the drying drum, the residual heat inside the drying drum is fully utilized, improving energy efficiency and accelerating the drying speed of the fabric. This ensures the uniformity of fabric drying and reduces problems such as mold growth, discoloration, odor, and dimensional deviations in subsequent processing caused by insufficient drying.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0045] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product.

[0050] like Figure 1 and Figure 2 The diagram illustrates a drying apparatus for producing textile fabric 3 according to an embodiment of the present invention, used for drying textile fabric 3 containing moisture. The drying apparatus comprises a frame 1, several drying cylinders 2, and supports 4 mounted on the drying cylinders 2. Specifically, the drying cylinders 2 are arranged at certain intervals on the frame 1, and the textile fabric 3 is wound sequentially around these drying cylinders 2 in an S-shape. The drying cylinders 2 are used to heat and dry the textile fabric 3. The supports 4 are detachably mounted on the drying cylinders 2. It should be noted that the supports 4 can also be directly mounted on the frame 1. An external heating plate 5 is mounted on the supports 4, and a heating coil 6 is installed inside the external heating plate 5. The heating coil 6 is interconnected with the interior of the drying cylinders 2. This design allows the hot air inside the drying cylinders 2 to enter the heating coil 6 after heating the drying cylinders 2, while the external heating plate 5 is specifically used to heat the textile fabric 3 between two adjacent drying cylinders 2.

[0051] For example, such as Figure 1 As shown, during operation, after the equipment starts, the heat source inside the drying cylinder 2 begins to work, generating hot air that first heats the drying cylinder 2 itself, raising the temperature of the cylinder wall. When the textile fabric 3 is wrapped around the drying cylinder 2, the heat from the cylinder wall is transferred to the fabric, heating and drying it. Simultaneously, the hot air inside the drying cylinder 2 only enters the heating coil 6 after the cylinder 2 is completely filled, ensuring that the heat distribution across the cylinder wall is roughly uniform. It should be noted that a valve is installed at the exhaust port 220 of the drying cylinder 2. When the air pressure inside the drying cylinder 2 increases to a preset pressure value, the valve automatically opens, allowing hot air to enter the heating coil 6. The heating coil 6 then transfers heat to the external heating plate 5, which in turn heats the textile fabric 3 suspended between adjacent drying cylinders 2. In this way, the fabric is continuously heated throughout the entire transfer process, avoiding the temperature drop problem that occurs with traditional equipment when the fabric is between adjacent drying cylinders 2.

[0052] In summary, on the one hand, by heating the fabric between adjacent drying cylinders 2 using the external heating plate 5, the temperature of the fabric during transport is effectively prevented, avoiding repeated heating and cooling, and protecting the overall structure of the textile fabric 3. On the other hand, since the heating coil 6 is connected to the inside of the drying cylinder 2, the residual heat inside the drying cylinder 2 is fully utilized, improving energy efficiency and accelerating the drying speed of the fabric. This ensures the uniformity of fabric drying and reduces problems such as mold growth, discoloration, odor, and dimensional deviations in subsequent processing caused by insufficient drying.

[0053] In some examples, the drying cylinder 2 has an air inlet 230 for introducing hot air and an exhaust outlet 220 for discharging hot air. Both the air inlet 230 and the exhaust outlet 220 are located at the center of both end faces of the drying cylinder 2, facilitating the connection of external pipes to the air inlet 230 and the exhaust outlet 220. Specifically, the drying cylinder 2 includes a heat-conducting cylinder body 21, a fixed end cap 22, and a movable end cap 23. The fixed end cap 22 is fixedly disposed at one end of the heat-conducting cylinder body 21, and is fastened to the end of the heat-conducting cylinder body 21, serving to seal one end of the heat-conducting cylinder body 21. The end of the fixed end cap 22 away from the heat-conducting cylinder body 21 is rotatably connected to the frame 1. The support 4, located near the fixed end cap 22, is directly sleeved on the fixed end cap 22, so that the support 4 does not rotate with the fixed end cap 22. The exhaust outlet 220 is located on the first shaft tube of the fixed end cap 22. Additionally, it should be noted that a sprocket is fixedly installed on the outside of the fixed end cover 22. This sprocket is a driven sprocket. A geared motor is installed on the frame 1, and a driving sprocket is installed at the output end of the geared motor. The chain is sequentially wound around the driven sprocket and the driving sprocket of each drying cylinder 2. In this way, when the geared motor drives, it can drive several drying cylinders 2 to rotate synchronously, so as to ensure that the textile fabric 3 will not be damaged by excessive stretching during the drying process.

[0054] Secondly, when the fixed end cap 22 rotates, it can drive the heat-conducting cylinder 21 to rotate as well. In this way, the heat-conducting cylinder 21 can serve as a power source for the movement of the textile fabric 3, driving the textile fabric 3 to continuously dry. The movable end cap 23 is detachably set at the other end of the heat-conducting cylinder 21. Specifically, the movable end cap 23 is also directly fastened to the heat-conducting cylinder 21, but a sealing ring is set at the connection between the two for sealing. The reason for the detachable connection is that the inside of the heat-conducting cylinder 21 needs to be cleaned and impurities removed after a period of production. In addition, the end of the movable end cap 23 away from the heat-conducting cylinder 21 is fixedly connected to the frame 1 through the second shaft tube. The movable end cap 23 is mainly used to support the heat-conducting cylinder 21 and to seal the other end of the heat-conducting cylinder 21. The air inlet 230 is opened on the second shaft tube of the movable end cap 23. The bracket 4 is connected to the movable end cap 23 near the movable end cap 23 through a flange to ensure that the bracket 4 does not rotate with the heat-conducting cylinder 21.

[0055] For example, such as Figure 1 and Figure 3 As shown, during operation, external hot air enters the heat-conducting cylinder 21 through the air inlet 230. The hot air flows inside the heat-conducting cylinder 21, transferring heat to the cylinder and raising its temperature, thereby heating and drying the textile fabric 3 on its surface. During the hot air flow, the fixed end cap 22 rotates with the heat-conducting cylinder 21, ensuring its normal operation. Simultaneously, the hot air after heat exchange is discharged through the exhaust port 220. When maintenance or cleaning of the drying cylinder 2 is required, the movable end cap 23 can be removed from the heat-conducting cylinder 21. Since the movable end cap 23 is slidably connected to the heat-conducting cylinder 21, the disassembly process is more convenient.

[0056] The fixed end cap 22 is rotatably connected to the frame 1, enabling the heat-conducting cylinder 21 to rotate smoothly, ensuring continuous transport of the textile fabric 3 and smooth drying process. The detachable movable end cap 23 facilitates maintenance and cleaning of the inside of the drying cylinder 2, helping to maintain its good working condition and extend the equipment's service life. The air inlet 230 and exhaust outlet 220 ensure smooth flow of hot air inside the drying cylinder 2, improving heat exchange efficiency and thus enhancing the drying effect of the fabric.

[0057] In some examples, the support 4 includes two side rods 41, which are respectively disposed at both ends of the heat-conducting cylinder 21. One side rod 41 is sleeved with the fixed end cover 22 at one end, and the other side rod 41 is fixedly connected to the movable end cover 23 at one end. The external heating plate 5 is hinged between the two side rods 41 and is located on the outside of the heat-conducting cylinder 21. It should be noted that the two side rods 41 can be adjusted in position according to the winding path of the textile fabric 3 to meet the winding and weaving requirements of the textile fabric 3, ensuring that the external heating plate 5 can contact the suspended textile fabric 3 without excessively pulling on the textile fabric 3.

[0058] For example, such as Figure 3 and Figure 4As shown, during equipment operation, since one side rod 41 is sleeved with the fixed end cover 22, when the fixed end cover 22 drives the heat-conducting cylinder 21 to rotate, the side rod 41 sleeved with the fixed end cover 22 will not rotate with the fixed end cover 22, while the other side rod 41 fixedly connected to the movable end cover 23 will also remain stationary. This allows the side rod 41 to provide stable support for the external heating plate 5. The external heating plate 5 is hinged between the two side rods 41 and can be adjusted in angle according to actual needs to ensure that it can accurately heat the textile fabric 3 between the two adjacent drying cylinders 2. In fact, the external heating plate 5 has a slight pushing effect on the textile fabric 3 it contacts, which allows the textile fabric 3 to fit more closely to the external heating plate 5, achieving a smooth ironing effect.

[0059] The side support frame 41 provides stable support for the external heating plate 5, allowing it to be securely installed in a suitable position and ensuring smooth external heating. The side support frame 41 accommodates the rotation of the heat-conducting cylinder 21, ensuring the overall stability of the support frame 4. Furthermore, the angle of the external heating plate 5 can be flexibly adjusted, accommodating not only different winding methods of the textile fabric 3 but also textile fabrics of varying thicknesses and types, thus improving the equipment's applicability.

[0060] In some examples, a correction plate 42 is provided at the end of the side rod 41 away from the heat-conducting cylinder 21. The correction plates 42 on the two side rods 41 work together to correct the deviation of the textile fabric 3. Specifically, the correction plate 42 and the side rod 41 are an integral structure, which can be understood as the correction plate 42 being a separate outward extension of the side rod 41.

[0061] For example, such as Figure 1 and Figure 3 As shown, it is understandable that because the distance between the two adjacent drying cylinders 2 is relatively large, the textile fabric 3 will experience a slight deviation during the drying process. When the textile fabric 3 deviates during transmission, the edge of the fabric will contact the correction plate 42. The correction plate 42 will exert a lateral pushing force on the fabric, gradually returning it to the correct transmission track. Since the two correction plates 42 are respectively set on both sides of the fabric, they can restrict and guide the fabric from two directions, ensuring that the fabric is always transmitted along the predetermined path.

[0062] This effectively prevents uneven drying of the textile fabric due to misalignment during the drying process, ensuring that all parts of the fabric receive sufficient heating and drying. Simultaneously, it avoids damage caused by friction between the fabric and other equipment components after misalignment, reducing fabric waste and improving production quality and efficiency.

[0063] In some examples, the external heating plate 5 includes a strip-shaped base 51 and a cover plate 53. The strip-shaped base 51 has an installation space 52 inside, and the heating coil 6 is disposed in the installation space 52. The length of the strip-shaped base 51 is the same as the length of the heat-conducting cylinder 21. The cover plate 53 is detachably mounted on the strip-shaped base 51 to cover the installation space 52. Several heat dissipation holes 510 are provided at intervals on the cover plate 53. The function of these heat dissipation holes 510 is to transfer the heat from the heating coil 6 to the textile fabric 3.

[0064] It should be noted that the external heating plate 5 has two configuration options. First, the strip base 51 itself has poor thermal conductivity, while the cover plate 53 has good thermal conductivity. In this configuration, the cover plate 53 directly contacts the textile fabric 3, allowing heat to escape through the heat dissipation holes 510 on the cover plate 53, thus drying the textile fabric 3. It is understood that although the panel and the strip base 51 are detachably connected, using bolts or fasteners, the surface of the cover plate 53 must be smooth. Second, the strip base 51 itself also has good thermal conductivity, allowing some of the heat from the heating coil 6 to dissipate outwards through the strip base 51. This ensures a higher temperature environment between the adjacent heating coil and the drying cylinder 2, reducing heat loss from the textile fabric 3.

[0065] Secondly, it is important to emphasize that the heating gas inside the drying cylinder 2 is steam. Traditional drying cylinders 2 directly input steam at a suitable temperature, filling the entire cylinder with steam, then heating it. Steam is then added again to maintain a positive pressure inside the cylinder. The steam condenses into water before being discharged. This results in the drying cylinder 2 being under high pressure for an extended period during the drying of the textile fabric 3. After a section of fabric 3 is dried, the first priority is to drain the condensate, leading to a longer downtime and a brief heating and cooling process in the drying cylinder 2. However, in this device, the steam in the drying cylinder 2 is flowing. The steam heats the drying cylinder 2 as it flows from the inlet 230 to the outlet, resulting in less condensate production compared to existing drying cylinders 2. Furthermore, the longitudinally arranged, adjacent drying cylinders 2 in this application have a larger spacing, preventing excessive contact between the textile fabric 3 and the bottom of the drying cylinder 2, a condensate accumulation area. This avoids uneven heating and cooling, which is beneficial for the drying of the textile fabric 3.

[0066] For example, such as Figure 5As shown, specifically, during operation, the heating coil 6 is heated by the hot air introduced from inside the drying cylinder 2 within the installation space 52. The generated heat is dissipated through the heat dissipation holes 510 on the cover plate 53, directly acting on the textile fabric 3 between two adjacent drying cylinders 2 to heat and dry the fabric. When it is necessary to inspect or replace the heating coil 6, the cover plate 53 can be removed from the strip seat 51, which is very convenient. The length of the strip seat 51 is the same as that of the heat-conducting cylinder 21, which ensures that the heating range of the external heating plate 5 on the fabric matches the heating range of the drying cylinder 2, ensuring that the fabric is heated evenly. The removable cover plate 53 facilitates the maintenance and inspection of the heating coil 6, reducing the maintenance cost of the equipment. The setting of the heat dissipation holes 510 allows the heat to be concentrated and evenly transferred to the fabric, improving heating efficiency and further ensuring the drying effect of the fabric.

[0067] In some examples, the drying equipment also includes an annular nozzle 8 and a turntable 10. The annular nozzle 8 is fixedly mounted on the movable end cover 23, located inside the heat-conducting cylinder 21 and concentrically arranged with the movable end cover 23. Several air nozzles 9 are arranged on the annular nozzle 8 at circumferential intervals. The turntable 10 is rotatably mounted on the movable end cover 23. Several fan blades 11 are arranged circumferentially on the turntable 10. The air nozzles 9 can spray air onto the fan blades 11, thereby driving the fan blades 11 and the turntable 10 to rotate. It should be noted that a turntable 10 and a fan blade 11 are also provided on the end face of the fixed end cover 22 near the heat-conducting cylinder 21, but no annular nozzle 8 is provided. The turntable 10 and the fan blade 11 on the fixed end cover 22 can rotate with the fixed end cover 22. The fan blade 11 on the fixed end cover 22 and the annular nozzle 8 blow the fan blade 11 in opposite directions, thereby increasing the turbulence on the steam in the drying cylinder 2. This not only allows the newly entered steam to mix fully and quickly with the steam in the drying cylinder 2, but also ensures that the temperature of the air inlet 230 and the air outlet 220 of the drying cylinder 2 are almost the same. Therefore, the internal pressure of the drying cylinder 2 of this device is much lower than the internal pressure of the traditional drying cylinder 2. Moreover, the drying effect on the cylinder wall of the drying cylinder 2 is the same at all locations. Furthermore, if the interior of the traditional drying tube is corroded in some places due to the corrosion of condensate and steam, the positive pressure state of the drying cylinder 2 will cause the corroded parts to crack, and in severe cases, an explosion may occur.

[0068] For example, such as Figure 6 and Figure 7 As shown, when hot air enters the heat-conducting cylinder 21 through the air inlet 230, some of the hot air enters the annular nozzle 8 and is then ejected through the jet nozzle 9. The ejected airflow acts on the fan blades 11, causing them to rotate, which in turn causes the turntable 10 to rotate. The rotation of the turntable 10 creates airflow disturbance inside the heat-conducting cylinder 21, making the distribution of hot air inside the heat-conducting cylinder 21 more uniform.

[0069] The rotating disc 10 is driven by the jet nozzle 9, utilizing the kinetic energy of the hot air without the need for an additional power unit, thus saving energy. The airflow disturbance generated by the rotation of the disc 10 makes the hot air distribution inside the heat-conducting cylinder 21 more uniform, avoiding local overheating or underheating, thereby ensuring the uniformity of heating of the fabric by the heat-conducting cylinder 21 and further improving the drying quality of the fabric.

[0070] In some examples, an air passage 1001 is provided in the middle of the turntable 10, which is connected to the air inlet 230. A baffle 13 is provided in the air passage 1001 to turbulent the hot air entering the heat-conducting cylinder 21. It should be noted that a baffle 13 is also provided at the central hole of the fan blade 11. Because the baffle 13 installed in the air passage 1001 is stationary, while the baffle 13 at the central hole of the fan blade 11 can rotate with the turntable 10 and the fan blade 11, the baffle 13 at both locations can increase the turbulence effect on the airflow and also slightly obstruct the airflow entering the drying cylinder 2. This allows some gas to enter the distribution hood 12, increasing the gas pressure in the air inlet pipe 82.

[0071] For example, such as Figure 7 and Figure 8 As shown, when hot air enters the air passage 1001 from the air inlet 230, it collides with the baffle 13. The baffle 13 changes the flow direction of the hot air, causing turbulent airflow within the air passage 1001. This turbulent airflow, after entering the heat-conducting cylinder 21, further enhances the mixing and flow of the hot air, making the distribution of hot air within the heat-conducting cylinder 21 more uniform. The turbulence effect of the baffle 13 on the hot air further improves the uniformity of the hot air within the heat-conducting cylinder 21, avoiding stratification or local stagnation of hot air during transmission. This ensures temperature consistency in all parts of the heat-conducting cylinder 21, ensuring that the textile fabric 3 can be uniformly heated and dried, thus improving the drying effect.

[0072] In some examples, the annular nozzle 8 includes an annular air guide pipe 81, an air inlet pipe 82, and a flow divider 12. The flow divider 12 can form an air storage chamber with the inner wall of the air passage 1001 for supplying air to the air inlet pipe 82. The flow divider 12 is used to receive the airflow from the air inlet 230 and allow the airflow to enter the air inlet pipe 82. The annular air guide pipe 81 is fixedly mounted on the movable end cap 23, and several nozzles 9 are mounted on the annular air guide pipe 81. One end of the air inlet pipe 82 is mounted on the annular air guide pipe 81, and the other end is connected to the air passage 1001 to send some of the hot air in the air passage 1001 into the annular air guide pipe 81. The flow divider 12 is mounted on the inner wall of the air passage 1001, and the air inlet pipe 82 is connected to the flow divider 12. The flow divider 12 has an opening facing the air inlet 230.

[0073] For example, such as Figure 7 and Figure 8 As shown, when hot air enters the air passage 1001 from the air inlet 230, under the guidance of the diffuser 12, some of the hot air will enter the annular air guide pipe 81 through the air inlet pipe 82, and then be ejected through the nozzle 9 to drive the fan blade 11 to rotate. The opening of the diffuser 12 faces the air inlet 230, which can more effectively collect hot air and ensure a stable amount of hot air entering the annular air guide pipe 81. The diffuser 12 can reasonably distribute the hot air in the air passage 1001, ensuring that enough hot air enters the annular air guide pipe 81, and ensuring that the nozzle 9 can continuously and stably drive the fan blade 11 to rotate. The air inlet pipe 82 connects the air passage 1001 and the annular air guide pipe 81, realizing the rational utilization of hot air and improving energy utilization. The annular air guide pipe 81 and the nozzle 9 ensure that the airflow can act evenly on the fan blade 11, making the rotation of the turntable 10 more stable.

[0074] In some examples, the drying equipment also includes a hot gas inlet pipe 15 and a three-way valve 7. The hot gas inlet pipe 15 is installed through the movable end cover 23 and communicates with the air inlet 230. The first port of the three-way valve 7 is connected to the hot gas inlet pipe 15, the second port is connected to an external hot gas source, and the third port is connected to the exhaust end of the heating coil 6 via a hose. The three-way valve 7 can mix the cooled hot gas in the heating coil 6 with the hot gas in the hot gas source and then deliver it to the hot gas inlet pipe 15. Temperature monitors are installed inside the drying cylinder 2 and at the air inlet 230 to monitor the temperature of the mixed steam.

[0075] For example, such as Figure 4 As shown, during operation, hot air from an external heat source enters through the second port of the three-way valve 7. Simultaneously, hot air cooled by heat exchange in the heating coil 6 enters the third port of the three-way valve 7 through a hose. Inside the three-way valve 7, these two streams of hot air mix together, then enter the hot air input pipe 15 through the first port, and finally enter the drying cylinder 2 through the air inlet 230. By recovering and reusing the cooled hot air from the heating coil 6 through the three-way valve 7, mixing it with the hot air from the external heat source, and then re-entering the drying cylinder 2, energy utilization efficiency is improved and energy consumption is reduced. Furthermore, the temperature of the mixed hot air is more stable, avoiding the impact of temperature fluctuations from a single heat source on the drying effect and ensuring the stability of the drying process.

[0076] In some examples, a moisture-absorbing sponge layer 14 is removably provided on the cover plate 53 or the strip seat 51. It should be noted that the moisture-absorbing sponge layer 14 has a breathable effect and will not excessively affect the dissipation of heat.

[0077] For example, such as Figure 3 and Figure 4As shown, a moisture-absorbing sponge layer 14 is detachably installed on the cover plate 53 or strip seat 51 of the external heating plate 5. When the textile fabric 3 is heated and dried, water vapor will evaporate. The moisture-absorbing sponge layer 14, which is not in contact with the textile fabric 3, can absorb this water vapor, preventing water vapor from accumulating inside the equipment and preventing water vapor from re-adhering to the textile fabric 3, thus affecting the drying effect. After the moisture-absorbing sponge layer 14 has absorbed a certain amount of moisture, it can be removed from the cover plate 53 or strip seat 51 for drying or replacement, ensuring its continuous moisture absorption capacity. Secondly, the sponge layer in contact with the textile fabric 3 will perform simple moisture absorption and drying on the textile fabric 3 due to the slight pushing effect of the external heating plate 5, improving the drying effect of the textile fabric. Moreover, because the moisture-absorbing layer has a certain thickness and flexibility, it can also prevent the textile fabric 3 from being torn. The setting of the moisture-absorbing sponge layer 14 effectively absorbs the water vapor generated during the drying process, avoids secondary contamination of the fabric by water vapor, ensures the drying quality of the fabric, and speeds up the drying process. The detachable and portable installation design makes the maintenance and replacement of the moisture-absorbing sponge layer 14 very convenient, ensuring the continuous and stable operation of the equipment.
