Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a reduction steaming box. Background Technology

[0002] Existing reduction steamers include a chamber, a guide roller system, a steam generator, and sealing components at the inlet and outlet ends of the chamber. The fabric is guided from the inlet end to the outlet end by the guide roller system, and then steam is generated by the steam generator. After the fabric is dyed, it undergoes reduction and color fixing with steam. The generated steam circulates within the chamber. However, since it relies solely on the sealing components at the inlet and outlet ends of the chamber to reduce steam leakage, some steam can still escape from the sealing components to the outside of the chamber. This results in low steam utilization and increased energy consumption of the steam generator, leading to higher costs.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model discloses a reduction steaming chamber to solve the problems that some steam can still escape from the sealing components to the outside of the chamber, resulting in low steam utilization and increased energy consumption and cost of the steam generator.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A reducing steam oven, characterized in that it comprises:

[0007] The steamer body has a cloth inlet and a cloth outlet at the lower ends of the left and right sides, respectively; inside the steamer body, a partition is provided on the right side of the cloth inlet, which separates the interior of the steamer body into a low temperature zone and a high temperature zone, and the partition is provided with a roller seal; the cloth inlet is provided with a first sealing device, and the cloth outlet is provided with a second sealing device.

[0008] A guide roller system is located inside the steaming chamber; the guide roller system guides the fabric through the inlet, low temperature zone, roller seal, high temperature zone and outlet in sequence.

[0009] A steam generator is located at the bottom of the steam oven body, and the steam outlet of the steam generator is located at the top of the steam generator and communicates with the interior of the steam oven body.

[0010] A further technical solution is that a fabric plate is hinged to the top of the partition plate at the bottom end of the roller seal. When the guide roller system conducts the fabric through the roller seal, the fabric plate deflects in the direction of fabric conduction, and the top of the fabric plate contacts and organizes the fabric.

[0011] A further technical solution is that the guide roller system includes a feed roller, a low-temperature guide roller, a fabric-forming roller, a high-temperature active roller, a high-temperature passive roller, a pressure detection roller, and a discharge roller; several feed rollers are spaced apart on the outer side of the steaming chamber body near the feed inlet; several low-temperature guide rollers are spaced apart in the low-temperature zone; the fabric-forming roller is located at the roller seal and at the upper end of the fabric-forming plate; several high-temperature active rollers and several high-temperature passive rollers are located in the upper and lower layers of the high-temperature zone; the pressure detection roller is located in the high-temperature zone, and a fabric pressure sensor is provided on the outer side of the steaming chamber body, with the front end of the pressure detection roller connected to the fabric pressure sensor; the discharge roller is located inside the second sealing device.

[0012] A further technical solution is that the first sealing assembly includes a heating tube and a turning material trough. The heating tube is a slit-like channel located at the bottom end of the fabric inlet. The turning material trough is movably located at the bottom end of the fabric inlet. When the turning material trough is in a horizontal position, it is filled with reducing liquid, and the heating tube is immersed in the turning material trough. When the fabric passes through the fabric inlet, it is liquid-sealed and fed in. When the turning material trough is lowered, the fabric is vapor-sealed and fed in.

[0013] A further technical solution is that the second sealing component includes a fabric outlet liquid seal groove, which is located at the bottom end of the fabric outlet, and the fabric is liquid-sealed out through the fabric outlet liquid seal groove.

[0014] A further technical solution is that a temperature sensor and a box micro-pressure sensor are also provided on the outside of the steam oven body, and the detection ends of the temperature sensor and the box micro-pressure sensor extend into the interior of the steam oven body.

[0015] A further technical solution is that the top of the steamer body is provided with an auxiliary heating layer, the auxiliary heating layer is provided with a coil tube, the coil tube bends in a serpentine shape from left to right, the coil tube is filled with heat-conducting oil, and the bottom of the auxiliary heating layer is also covered with aluminum shavings; the top of the auxiliary heating layer is also provided with a heat insulation layer, and the heat insulation layer is filled with asbestos.

[0016] A further technical solution is that the steam generating box is equipped with a U-shaped liquid level display tube and an automatic water replenishment port. Several steam pipes are arranged horizontally at intervals at the bottom of the steam generating box. The openings of the steam pipes face downwards, and the bottom of the steam pipes is equipped with impact plates. Several anti-splash plates are arranged vertically and horizontally at the steam outlet of the steam generating box.

[0017] The beneficial effects of this utility model embodiment are as follows:

[0018] (I) A reduction steaming box includes a steaming box body, a guide roller system, and a steam generator. The lower ends of the left and right sides of the steaming box body are respectively provided with a fabric inlet and a fabric outlet. The guide roller system guides the fabric from the fabric inlet into the steaming box body. The steam generator is started and generates steam. Inside the steaming box body, on the right side of the fabric inlet, there is a partition. The partition separates the inside of the steaming box body into a low-temperature zone and a high-temperature zone. The partition has a roller seal to allow the fabric to pass through. The steam is confined to the high-temperature zone by the partition. The fabric enters the low-temperature zone for preheating to remove moisture from the fabric surface and then enters the high-temperature zone for reduction and color fixing. The partition physically blocks the diffusion of high-temperature steam to the low-temperature zone. Together with the first sealing component and the second sealing component at both ends of the steaming box body, the steam escape rate is reduced, the steam utilization rate is improved, and the energy consumption of the steam generator is reduced. At the same time, the partition separates the low-temperature zone and the high-temperature zone. The fabric is first preheated in the low-temperature zone to avoid direct contact with the high-temperature steam and to protect the fabric material.

[0019] (ii) Furthermore, a fabric plate is hinged to the top of the partition at the bottom of the roller seal. When the fabric roller conducts the fabric through the roller seal, the fabric enters the roller seal along the lower end of the fabric roller. The fabric plate is deflected to the right by the thrust in the direction of fabric conduction. Its top end contacts and smooths the fabric surface, eliminating wrinkles, deviations or knots in the fabric, and ensuring that the fabric enters the high-temperature zone flat. Specifically, a limiting frame is provided on the lower left side of the fabric plate. The limiting frame allows the fabric plate to rotate only to the right. When the fabric plate wants to rotate to the left, the bottom end of the limiting frame abuts against the partition at the lower end of the roller seal, keeping the fabric plate in a vertical state. The limiting frame restricts the fabric plate to rotate only to the right through physical constraints. When the fabric runs abnormally or is subjected to reverse force, the bottom end of the limiting frame contacts the partition to form a rigid support, preventing the fabric plate from swinging back to the left and keeping it in a vertical state. The fabric plate not only avoids the fabric from getting stuck due to reverse deflection, but also maintains the effective separation of the low temperature zone and the high temperature zone by the partition, preventing steam leakage and ensuring the continuous stability of fabric transmission and the accuracy of the internal environment control of the steam chamber.

[0020] (III) Furthermore, the first sealing assembly achieves a dual-selection design of steam seal and liquid seal at the inlet through the synergistic effect of the heating tube and the tilting trough. The heating tube is designed with a slit-type channel at the bottom of the inlet, which not only preheats the fabric entering the low-temperature zone, but also forms a negative pressure in the low-temperature zone through the airflow generated by the heating, effectively preventing steam from overflowing. The built-in anti-vacuum collapse low-pressure protection device can automatically adjust the negative pressure intensity to avoid structural deformation caused by pressure imbalance in the low-temperature zone. The tilting trough achieves lifting control through a multi-link mechanism (linkage of the first link, the second link, the third link and the piston rod). When the trough is raised to the horizontal position, the internal reducing liquid immerses the heating tube to form a liquid seal channel. When the fabric is immersed in the liquid, a liquid seal is achieved. When the piston rod retracts, it drives the link to deflect, and the guide rod moves down along the guide groove on the left side of the support leg. The tilting trough tilts downward and disengages from the heating tube. At this time, the fabric enters through the negative pressure steam seal, adapting to different process requirements and improving the process flexibility of the device.

[0021] (iv) Furthermore, the top of the steam oven body is equipped with an auxiliary heating layer, within which is a coiled tube that bends serpentinely from left to right. The coiled tube is filled with heat-conducting oil, and aluminum shavings are laid at the bottom of the auxiliary heating layer. An insulation layer, filled with asbestos, is also located at the top of the auxiliary heating layer. The heat-conducting oil circulating in the coiled tube absorbs waste heat from the steam due to its high heat capacity. The serpentine path from left to right extends the heat exchange time, and combined with the high thermal conductivity of the aluminum shavings at the bottom, heat is evenly diffused to the bottom surface of the auxiliary heating layer, compensating for the temperature gradient in the top area and preventing excessive temperature differences in the upper part of the oven due to rising steam. The insulation layer at the top is filled with asbestos to form a thermal barrier, reducing heat loss to the external environment, lowering energy consumption, and maintaining the stability of the thermal field inside the oven. Specifically, the top of the steam oven body is equipped with a removable small window. This window can be opened during cleaning and maintenance to quickly cool the temperature inside the oven and prevent the gap between the guide roller at the top and the top plate from being too small, which could lead to excessively high temperatures. The design of the detachable small window combines practicality and safety. During daily operation, closing the small window can prevent heat loss, while opening the small window during cleaning and maintenance can accelerate the discharge of steam inside the chamber to achieve rapid cooling, and also provide heat dissipation space for the steam chamber body. This avoids thermal expansion deformation caused by the small gap between the roller and the top plate under high temperature conditions, thereby improving the thermal energy utilization rate while ensuring the long-term reliability and maintenance convenience of the equipment.

[0022] (V) Furthermore, the steam generator is equipped with a U-shaped liquid level display tube and an automatic water replenishment port. Several steam pipes are horizontally spaced at the bottom of the steam generator, with their openings facing downwards. An impact plate is located at the bottom of each steam pipe, allowing steam to directly impact the plate. The steam generator monitors and maintains a stable water level in real time through the U-shaped liquid level display tube and the automatic water replenishment port, preventing the steam pipes from drying out or overflowing. The downward-facing design of the horizontally spaced steam pipes at the bottom, combined with the impact plate, ensures that the steam impacts the plate surface at high speed during generation, breaking up large molecular clusters, improving steam uniformity and heat exchange efficiency, and reducing energy waste. Several anti-splash plates are staggered at the steam outlet of the steam generator. These staggered anti-splash plates intercept water droplets through multiple deflections, ensuring that the output steam is dry and pure, preventing liquid water from entering the steam generator and interfering with fabric processing or reducing temperature field stability. Specifically, the steam generator is also equipped with pressure and temperature / humidity sensors. The built-in pressure and temperature / humidity sensors dynamically collect pressure, temperature, and humidity data inside the generator, and link them with the steam pipe power adjustment and automatic water replenishment system to ensure that the steam generation rate is precisely matched with the process requirements. This achieves efficient, uniform, and controllable steam supply, provides a stable and reliable steam source for the generator body, and reduces energy consumption while extending the service life of the equipment.

[0032] Example:

[0033] A reduction steamer includes a steamer body 100, a guide roller system, and a steam generator 300.

[0034] Figure 1 This is a front view of the internal structure of a reduction steamer according to the present invention. Figure 2 for Figure 1 A magnified view at point A. (See image below.) Figures 1-2As shown, the lower ends of the left and right sides of the steamer body 100 are respectively provided with a cloth inlet 101 and a cloth outlet 102. Inside the steamer body 100, to the right of the cloth inlet 101, there is a partition 110, which separates the interior of the steamer body 100 into a low-temperature zone 103 and a high-temperature zone 104. The partition 110 has a roller seal 111. The cloth inlet 101 is provided with a first sealing device, and the cloth outlet 102 is provided with a second sealing device.

[0035] like Figures 1-2 As shown, the guide roller system is located inside the steam chamber body 100. The guide roller system guides the fabric sequentially through the inlet 101, the low-temperature zone 103, the roller seal 111, the high-temperature zone 104, and the outlet 102. Exemplarily, the guide roller system includes an inlet roller 201, a low-temperature guide roller 202, a fabric-forming roller 203, a high-temperature active roller 204, a high-temperature passive roller 205, a pressure detection roller 206, and an outlet roller 207. Three inlet rollers 201 are spaced apart on the outer side of the steam chamber body 100 near the inlet 101. Five low-temperature guide rollers 202 are spaced apart in the low-temperature zone 103, with four low-temperature guide rollers 202 arranged side-by-side on the left side of the low-temperature zone 103 and one low-temperature guide roller 202 located on the right side of the low-temperature zone 103. The fabric-forming roller 203 is located at the roller seal 111 and is situated at the upper end of the fabric-forming plate 120. Several high-temperature active rollers 204 and several high-temperature passive rollers 205 are staggered and spaced between the upper and lower layers of the high-temperature zone 104. For example, the upper layer has two high-temperature active rollers 204 and one high-temperature passive roller 205, with the high-temperature passive roller 205 positioned between the two high-temperature active rollers 204. Correspondingly, the lower layer has two high-temperature passive rollers 205 and one high-temperature active roller 204, with the high-temperature active roller 204 positioned between the two high-temperature passive rollers 205. Four pressure detection rollers 206 are located within the high-temperature zone 104 and spaced between the roller sets in the upper layer. For example, the first pressure detection roller 206 is located on the upper leftmost side of the high-temperature zone 104, where the fabric is transferred from the upper fabric roller 203 to the first pressure detection roller 206. To the right of the first pressure detection roller 206 and on the corresponding lower layer, two high-temperature active rollers 204 are respectively arranged, so that the fabric passing through the pressure detection rollers 206 can be better transferred backward. Four fabric pressure sensors 208 are provided on the outside of the steamer body 100, and the front end of the pressure detection roller 206 is connected to the fabric pressure sensor 208. The fabric discharge roller 207 is located inside the second sealing device.

[0036] Figure 3 for Figure 1 A magnified view at point B. (See image below.) Figure 1 and Figure 3 As shown, the steam generator 300 is located at the bottom of the steam chamber body 100, and the steam outlet 301 of the steam generator 300 is located at the top of the steam generator 300 and communicates with the interior of the steam chamber body 100.

[0037] like Figure 2 As shown, further, a fabric plate 120 is hinged to the top of the bottom part of the partition plate 110 at the roller seal 111. When the fabric roller 203 conducts the fabric through the roller seal 111, the fabric enters the roller seal 111 along the lower end of the fabric roller 203. The fabric plate 120 is deflected to the right by the thrust in the direction of fabric conduction. Its top end contacts and smooths the surface of the fabric, eliminating wrinkles, deviations or knots in the fabric, and ensuring that the fabric enters the high temperature zone 104 flat. Specifically, a limiting frame 121 is provided on the lower left side of the fabric plate 120. The limiting frame 121 allows the fabric plate 120 to rotate only to the right. When the fabric plate 120 wants to rotate to the left, the bottom end of the limiting frame 121 abuts against the partition plate 110 at the lower end of the roller seal 111, keeping the fabric plate 120 in a vertical state. The limiting frame 121 restricts the fabric plate 120 to rotate only to the right in one direction through physical constraints. When the fabric runs abnormally or is subjected to reverse force, the bottom end of the limiting frame 121 contacts the partition plate 110 to form a rigid support, preventing the fabric plate 120 from swinging back to the left and keeping it in a vertical state. The fabric plate 120 avoids the fabric from getting stuck due to reverse deflection and maintains the effective separation of the low temperature zone 103 and the high temperature zone 104 by the partition plate 110, preventing steam leakage and ensuring the continuous stability of fabric transmission and the accuracy of the internal environment control of the steam chamber.

[0038] like Figure 2As shown, the first sealing assembly further includes a heating tube 400 and a tilting trough 500. The heating tube 400 is a slit-like channel located at the bottom of the fabric inlet 101. The heating tube 400 can initially heat the fabric entering the low-temperature zone 103, causing a negative pressure in the low-temperature zone 103 to prevent steam from escaping. The heating tube 400 is also equipped with a low-pressure protection device to prevent excessive negative pressure in the low-temperature zone 103 from causing expansion and damage. The tilting trough 500 is movably located at the bottom of the fabric inlet 101. When the tilting trough 500 is in a horizontal position, it is filled with reducing liquid, and the heating tube 400 is immersed in it. When the fabric passes through the fabric inlet 101, it is liquid-sealed; when the tilting trough 500 is lowered, it is vapor-sealed. Specifically, a first connecting rod 501 is vertically positioned within the tilting trough 500. The top of the first connecting rod 501 is connected to a second connecting rod 502 horizontally positioned within the tilting trough 500. The right end of the second connecting rod 502 is hinged to the top right side of the left-side support leg at the bottom of the steamer body 100. A piston rod 504 is located at the bottom right side of the support leg. The bottom end of the cylinder of the piston rod 504 is hinged to the bottom right side of the bracket. A third connecting rod 503 is also provided to the right of the second connecting rod 502. The third connecting rod 503 is integrally formed with the second connecting rod 502. The right side of rod 503 is hinged to the top of the rod of piston rod 504. A guide groove 130 is also provided on the left side of the support leg along the movement trajectory of the tilting trough 500. Two guide rods 505 are provided at the upper and lower ends of the rear side of the first connecting rod 501. The piston rod 504 extends or retracts. The rod of piston rod 504 pushes or pulls the third connecting rod 503. The third connecting rod 503 and the second connecting rod 502 drive the first connecting rod 501 to deflect downward or upward. The guide rods 505 move downward or upward along the guide groove 130. The tilting trough 500 is lowered or raised to a horizontal position. The first sealing assembly achieves a dual-seal design for the fabric inlet 101 through the synergistic action of the heating tube 400 and the tilting trough 500, allowing for both steam and liquid sealing. The heating tube 400, designed as a slit-like channel at the bottom of the fabric inlet 101, provides initial heating to the fabric entering the low-temperature zone 103 and creates negative pressure in the low-temperature zone 103 through the airflow generated by heating, effectively preventing steam leakage. The built-in anti-vacuum collapse low-pressure protection device automatically adjusts the negative pressure intensity to prevent structural deformation in the low-temperature zone 103 due to pressure imbalance. The tilting trough 500 is connected via a multi-link mechanism... The linkage (first connecting rod 501, second connecting rod 502, third connecting rod 503 and piston rod 504) realizes lifting control. When the material tank is raised to the horizontal position, the internal reducing liquid immerses the heating tube 400 to form a liquid seal channel. When the cloth is immersed in the liquid, the liquid seal is achieved. When the piston rod 504 retracts, it drives the connecting rod to deflect. The guide rod 505 moves down along the guide groove 130 on the left side of the support leg. The flipped material tank 500 tilts downward and disengages from the heating tube 400. At this time, the cloth is fed in through the negative pressure steam seal, which can adapt to different process requirements and improve the process flexibility of the device.

[0039] like Figure 1 As shown, the second sealing assembly further includes a fabric outlet liquid seal groove 600, which is located at the bottom end of the fabric outlet 102. The fabric is liquid-sealed out through the fabric outlet liquid seal groove 600. The second sealing component, through the design of the liquid sealing groove 600, achieves liquid sealing at the bottom of the outlet 102. After the fabric is treated in the high-temperature zone 104, it needs to pass through the reducing liquid or water-based liquid stored in the liquid sealing groove when it is discharged through the outlet 102. The liquid covers the gap between the fabric and the outlet 102, forming a physical barrier layer, which effectively prevents the high-temperature steam inside the steam chamber 100 from overflowing through the outlet 102, maintaining a stable micro-positive pressure environment inside the steam chamber 100, avoiding energy waste or deterioration of the working environment caused by steam leakage. At the same time, the liquid in the liquid sealing groove 600 can initially cool the high-temperature fabric, reduce the surface temperature of the fabric, reduce the risk of fiber shrinkage or oxidation caused by sudden cooling, and further fix the color or stabilize the reduction reaction effect through liquid wetting. In addition, the liquid sealing structure can also prevent external air backflow, prevent external impurities from entering the steam chamber 100 and interfering with the process conditions, and ensure the accuracy of steam purity and temperature and humidity control in the high-temperature zone 104, thereby achieving a balance between sealing performance, process continuity and fabric treatment quality.

[0040] like Figure 1 As shown, a temperature sensor 140 and a box micro-pressure sensor 150 are further provided on the outside of the steam oven body 100, and the detection ends of the temperature sensor 140 and the box micro-pressure sensor 150 extend into the interior of the steam oven body 100. Temperature sensor 140 and chamber micro-pressure sensor 150, installed on the outside of the steam chamber body 100, penetrate into the interior of the steam chamber body 100 through their detection ends to monitor the temperature distribution and pressure changes inside the steam chamber body 100 in real time. Temperature sensor 140 collects the actual temperature data of the high-temperature zone 104 to ensure stable steam heating efficiency and fabric reduction reaction conditions. Chamber micro-pressure sensor 150 accurately senses pressure fluctuations inside the steam chamber body 100. When the steam supply of the steam generator 300 or the efficiency of the sealing components changes, pressure feedback is used in conjunction with the steam generator 300 and the second sealing device (such as negative pressure control at the fabric inlet 101 and liquid level adjustment at the fabric outlet 102) to maintain the pressure environment inside the steam chamber body 100. This prevents steam leakage from increasing energy consumption and avoids structural deformation or external air backflow from interfering with the process flow due to negative pressure overload. The coordinated monitoring of both can also provide early warning of abnormal operating conditions, ensuring the efficient and accurate execution of the reduction steaming process.

[0041] Figure 4 This is a top view schematic diagram of the internal structure of the auxiliary heating layer in a reducing steam oven according to this utility model. Figure 1 and Figure 4As shown, the top of the steam oven body 100 is further provided with an auxiliary heating layer 160, within which is a coiled tube 161. The coiled tube 161 bends serpentinely from left to right and is filled with heat-conducting oil. Aluminum shavings are also laid at the bottom of the auxiliary heating layer 160. An insulation layer 170 is also provided at the top of the auxiliary heating layer 160, filled with asbestos. The heat-conducting oil circulating in the coiled tube 161 utilizes its high heat capacity to absorb waste heat from the steam. The serpentine path from left to right extends the heat exchange time, and combined with the high thermal conductivity of the aluminum shavings at the bottom, heat is evenly diffused to the bottom surface of the auxiliary heating layer 160, compensating for the temperature gradient in the top area and preventing excessive temperature differences at the top of the steam oven body 100 due to rising steam. The insulation layer 170 at the top is filled with asbestos to form a thermal barrier, reducing heat loss to the external environment, lowering energy consumption, and maintaining the stability of the internal thermal field. Specifically, the top of the steam oven body 100 is equipped with a removable small window. This window can be opened during cleaning and maintenance to quickly cool the interior temperature and prevent the gap between the top guide roller and the top plate from being too small, which could lead to excessively high temperatures. The removable window design balances practicality and safety. During normal operation, closing the window prevents heat loss, while opening it during cleaning and maintenance accelerates steam discharge from the steam oven body 100 for rapid cooling and provides ventilation space. This prevents thermal expansion and deformation caused by insufficient gap between the roller and the top plate under high temperatures, thus improving thermal efficiency while ensuring long-term reliability and ease of maintenance.

Figure 3 and Figure 5As shown, the steam generator 300 is further equipped with a U-shaped liquid level display tube 302 and an automatic water inlet 303. Several steam pipes 304 are horizontally spaced at the bottom of the steam generator 300, with the openings of the steam pipes 304 facing downwards. An impact plate 305 is provided at the bottom of the steam pipes 304. The steam generator 300 monitors and maintains the water level in the tank in real time through the U-shaped liquid level display tube 302 and the automatic water inlet 303, preventing the steam pipes 304 from dry burning or overflowing. The downward-facing design of the horizontally spaced steam pipes 304 at the bottom, together with the bottom impact plate 305, allows the steam to impact the plate surface at high speed when it is generated, breaking up the steam clusters, improving the uniformity of steam and the heat exchange efficiency, and reducing energy waste. The steam generator 300 has several anti-splash plates 306 arranged in a staggered pattern at the steam outlet 301. These plates intercept water droplets through multiple deflections, ensuring the output steam is dry and pure, and preventing liquid water from entering the steam generator body 100 and interfering with fabric processing or reducing temperature field stability. Specifically, the steam generator 300 is also equipped with pressure and temperature / humidity sensors. These sensors dynamically collect pressure, temperature, and humidity data within the steam generator body 100, linking them to the power adjustment of the steam pipe 304 and the automatic water replenishment system. This ensures precise matching between the steam generation rate and process requirements, achieving efficient, uniform, and controllable steam supply. This provides a stable and reliable steam source for the steam generator body 100, while reducing energy consumption and extending equipment lifespan.

[0043] In operation, this embodiment is as follows:

[0044] The fabric first enters the low-temperature zone 103 through the first sealing device of the inlet 101 via the feed roller 201. At this time, the tilting trough 500 selects a horizontal position as needed to immerse the fabric in the reducing liquid for liquid-sealed feeding or, after being lowered, achieves vapor-sealed feeding and preliminary preheating through the negative pressure generated by the heating pipe 400. The guide roller in the low-temperature zone 103 guides the movement of the fabric. Subsequently, the fabric passes through the sizing roller 203 at the roller seal 111 of the partition 110. After being deflected and sorted by the sizing plate 120, the fabric enters the high-temperature zone 104. In the high-temperature zone 104, the high-temperature active roller 204 and passive roller work together with the pressure detection roller 206 to conduct the fabric. The pressure detection roller 206 monitors the fabric in real time through the fabric pressure sensor 208. The steam generated by the heating pipe 400 at the bottom of the steam generator 300 is evenly fed into the steam chamber body 100 through the anti-splash plate 306. The anti-splash plate 306 at the steam outlet 301 prevents water droplets from splashing. At the same time, the U-shaped liquid level display tube 302 and the automatic water replenishment port 303 maintain a stable water level. The high-temperature steam performs reduction and color fixing treatment on the fabric in the high-temperature zone 104. The auxiliary heating layer 160 at the top of the steam chamber body 100 dissipates heat evenly through the heat transfer oil coil and aluminum shavings. The asbestos in the insulation layer 170 reduces heat loss. The temperature sensor 140 and the chamber micro-pressure sensor 150 monitor the internal environment. Finally, the fabric is output after being immersed and sealed in the liquid seal tank at the fabric outlet 102, completing the entire reduction steaming process.

[0045] In this embodiment, the partition 110 physically blocks the diffusion of high-temperature steam to the low-temperature zone 103. Together with the first and second sealing components at both ends of the steam chamber body 100, it reduces the steam escape rate, improves the steam utilization rate, and reduces the energy consumption of the steam generator 300. At the same time, the partition 110 separates the low-temperature zone 103 and the high-temperature zone 104. The fabric is first preheated in the low-temperature zone 103 to avoid direct contact between the fabric and the high-temperature steam, thus protecting the fabric material.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
