Description

Technical Field

[0001] This invention relates to the field of dyeing tanks, and more particularly to a temperature control system for a dyeing tank for cellulose acetate blends. Background Technology

[0002] In the dyeing and processing of acetate fiber blended fabrics, the performance of the dyeing bath temperature control system plays a crucial role in the dyeing quality. Acetate fiber has unique physicochemical properties, and its dyeing process requires extremely stringent conditions regarding temperature and dye liquor concentration uniformity. Even slight fluctuations in temperature or localized differences in dye liquor concentration can lead to serious quality problems such as uneven dyeing and color variations, affecting the fabric's quality and market value. Traditional dyeing bath temperature control methods typically employ a single heating element, such as a heating tube or heating coil, to directly heat the dye liquor and raise its temperature. However, this method suffers from several drawbacks. During heating, the temperature of the dye liquor rises rapidly around the heating element, while areas further away rise slowly, resulting in extremely uneven temperature distribution. This makes it difficult to meet the high temperature uniformity requirements for dyeing acetate fiber blends. Furthermore, during heating, dyes and auxiliaries in the dye liquor are prone to precipitation or aggregation due to localized high temperatures, leading to uneven dye concentration and further affecting the dyeing effect. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a temperature control system for a dyeing bath of cellulose acetate blends. In practical use, the combined use of liquid flow and bubble rising effectively improves the uniformity of dye liquor temperature, while simultaneously avoiding uneven dye liquor concentration and ensuring the effectiveness of temperature control.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A temperature control system for an acetate fiber blend dyeing tank includes a dyeing chamber with two symmetrically mounted support frames at its lower end. Slotted openings are provided on both the left and right side walls of the dyeing chamber. Multiple guide rollers are rotatably connected between the front and rear inner walls of the dyeing chamber, and a fabric body is mounted on each of the guide rollers. Two slotted openings pass through both ends of the fabric body. An agitation mechanism includes a drive motor mounted on the left side of the dyeing chamber. The output shaft of the drive motor extends into the dyeing chamber and is fixedly connected to a rotating shaft. Multiple agitator rods are fixedly connected to the outer side of the rotating shaft. A gas supply mechanism is used to supply gas into the dyeing chamber, utilizing the rising and bursting of the gas to promote liquid flow. A liquid circulation mechanism works in conjunction with the gas supply mechanism to improve the uniformity of the liquid temperature.

[0005] Preferably, the gas supply mechanism includes two piston cylinders symmetrically and fixedly connected to the right side of the dyeing chamber. Each of the two piston cylinders is provided with a piston plate that can slide back and forth. The two piston plates are fixedly connected by a fixing rod. The right end of the rotating shaft extends to the outside and is fixedly connected to a rotating disk. A drive rod is rotatably connected to the right eccentric part of the rotating disk. The other end of the drive rod is rotatably connected to one of the piston plates. The spaces on opposite sides of the two piston cylinders are connected to a first one-way pipe and a second one-way pipe. The other end of the first one-way pipe located on the rear side extends to the top space of the dyeing chamber, and the other end of the second one-way pipe located on the rear side extends to the bottom space of the dyeing chamber.

[0006] Preferably, a flow divider is fixedly connected to the inner top of the dyeing box, and a plurality of flow divider holes are opened in the inner top of the flow divider. The end of the second one-way tube located on the rear side away from the corresponding piston cylinder extends into the interior of the flow divider.

[0007] Preferably, a heating wire is installed inside the diverter plate, and a temperature sensor that works in conjunction with the heating wire is installed inside the dyeing box.

[0008] Preferably, the liquid circulation structure includes two cavities symmetrically arranged in the inner wall of the dyeing box. Multiple through holes are opened on the opposite sidewalls of the two cavities. The first one-way pipe located on the front side is connected to the cavity on the right side. A filter box is fixedly connected to the right side of the dyeing box. The other end of the second one-way pipe located on the front side is connected to the space on the left side of the filter box. The space on the right side of the filter box is connected to the cavity on the left side through a connecting pipe.

[0009] Preferably, each of the first and second one-way tubes is equipped with a one-way valve. The flow direction of the one-way valve inside the first one-way tube is one-way from the outside into the corresponding piston cylinder, and the flow direction of the one-way valve inside the second one-way tube is one-way from the piston cylinder to the outside.

[0010] Preferably, the device further includes a bubble-breaking mechanism, which includes a rectangular plate horizontally fixedly connected inside the dyeing box. The rectangular plate has a rectangular opening. A slidable shaking net is provided at the upper end of the rectangular plate. Two vertical plates are symmetrically fixedly connected to the lower end of the shaking net. The opposite sides of the two vertical plates are elastically connected to the corresponding inner wall of the dyeing box by springs. Guide plates are fixedly connected to the opposite sides of the two vertical plates. The upper ends of the two guide plates are in contact with the lower end of the rectangular plate and are slidably connected.

[0011] Preferably, an L-shaped abutment is fixedly connected to the outer side of the rotating shaft, a connecting strip is fixedly connected to the upper end of the shaking net, and a round-headed abutment is fixedly connected to the left side of the connecting strip, the round-headed abutment cooperating with the L-shaped abutment.

[0012] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The drive motor rotates the shaft and stirring rod, which can effectively agitate the dyeing liquid, so that the dye is evenly distributed, avoid local concentration differences, ensure uniform dyeing of the fabric, significantly improve dyeing quality, and reduce the defect rate caused by uneven dyeing. In conjunction with the temperature sensor and heating wire, it ensures temperature uniformity and improves the accuracy of the temperature control system.

[0013] 2. The rotating disc drives the drive rod to make the piston plate reciprocate, realizing the intake of gas at the top of the dyeing box and the compression of gas into the bottom space. The gas is evenly injected into the liquid through the distribution plate. The gas rises and bursts to promote the flow of liquid and enhance the dye mixing effect.

[0014] 3. The reciprocating motion of the piston plate creates liquid circulation, which not only further circulates the liquid but also filters out fibers in the dye liquor, preventing them from affecting the quality of the finished product. At the same time, the liquid flow impacts air bubbles, reducing their rising speed, increasing the possibility of bubble breaking, and promoting liquid mixing and temperature uniformity.

[0015] 4. The rotating shaft drives the L-shaped abutment rod to rotate, causing the shaking net to shake continuously, breaking up the rising air bubbles, making the bubbles smaller and evenly distributed in the dye, and then evenly bursting them, further improving the uniformity of liquid flow and enhancing the dyeing effect.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Reference Figures 1-6 A temperature control system for an acetate fiber blend dyeing tank includes a dyeing box 1. Two support frames 6 are symmetrically installed at the lower end of the dyeing box 1. Strip-shaped openings 2 are provided on the left and right side walls of the dyeing box 1. Multiple guide rollers 7 are rotatably connected between the front and rear inner walls of the dyeing box 1. A fabric body 3 is provided on the multiple guide rollers 7. The two ends of the fabric body 3 pass through the two strip-shaped openings 2 respectively and are connected to the external winding and unwinding device. Guided by the guide rollers 7, the fabric body 3 can move smoothly in the dyeing box 1 to realize continuous dyeing operation. The system also includes a stirring mechanism, which includes a drive motor 4 installed on the left side of the dyeing box 1. The output shaft of the drive motor 4 extends into the dyeing box 1 and is fixedly connected to a rotating shaft 10. Multiple stirring rods 11 are fixedly connected to the outside of the rotating shaft 10. After the drive motor 4 is started, it drives the rotating shaft 10 to rotate, thereby causing the stirring rods 11 to rotate in the dyeing box 1, stirring the dyeing liquid, making the dye distribution more uniform, avoiding local concentrations that are too high or too low, and improving the dyeing quality. The system also includes a gas supply mechanism for supplying gas into the dyeing chamber 1. The gas supply mechanism promotes liquid flow by using the rising and bursting of the gas. The gas supply mechanism includes two piston cylinders 19 symmetrically and fixedly connected to the right side of the dyeing chamber 1. Each piston cylinder 19 is provided with a piston plate 29 that can slide back and forth. The two piston plates 29 are fixedly connected by a fixing rod 31. The right end of the rotating shaft 10 extends to the outside and is fixedly connected to a rotating disk 20. A drive rod 32 is rotatably connected to the right eccentric part of the rotating disk 20. The other end of the drive rod 32 is rotatably connected to one of the piston plates 29. The spaces on opposite sides of the two piston cylinders 19 are connected to a first one-way pipe 21 and a second one-way pipe 30. The other end of the first one-way pipe 21 located on the rear side extends to the top space of the dyeing chamber 1, and the other end of the second one-way pipe 30 located on the rear side extends to the bottom space of the dyeing chamber 1. The rotation of the shaft 10 drives the rotating disk 20 to rotate, and through the action of the drive rod 32, the piston plate 29 reciprocates back and forth inside the piston cylinder 19. When the piston plate 29 moves forward, it draws in gas from the top space of the dyeing box 1 through the first one-way pipe 21; when the piston plate 29 moves backward, it forces the drawn-in gas into the bottom space of the dyeing box 1 through the second one-way pipe 30. A flow divider plate 16 is fixedly connected to the inner top of the dyeing box 1. Multiple flow divider holes 17 are opened on the inner top of the flow divider plate 16. The end of the second one-way tube 30 located on the rear side, away from the corresponding piston cylinder 19, extends into the interior of the flow divider plate 16. By using the flow divider holes 17, the injected gas can be more uniform.

[0021] This includes a liquid circulation mechanism that works in conjunction with a gas supply mechanism to improve the uniformity of liquid temperature. The liquid circulation structure includes two cavities 8 symmetrically arranged in the inner wall of the dyeing chamber 1. Multiple through holes 9 are provided on the opposite sidewalls of the two cavities 8. A first one-way pipe 21 located at the front communicates with the cavity 8 on the right. A filter box 12 is fixedly connected to the right side of the dyeing chamber 1. The other end of a second one-way pipe 30 located at the front communicates with the space on the left side of the filter box 12. The space on the right side of the filter box 12 is connected to the cavity 8 on the left side via a connecting pipe 5. Each first one-way pipe... Both pipe 21 and the second one-way pipe 30 are equipped with one-way valves. The one-way valve inside the first one-way pipe 21 allows the liquid to flow unidirectionally into the corresponding piston cylinder 19, while the one-way valve inside the second one-way pipe 30 allows the liquid to flow unidirectionally out of the piston cylinder 19. When the piston plate 29 moves backward, liquid is drawn into the right cavity 8 through the first one-way pipe 21. When the piston plate 29 moves forward, the drawn-in liquid is forced into the filter box 12 through the second one-way pipe 30. After filtration, the liquid enters the left cavity 8 through the connecting pipe 5 and finally flows out through the through hole 9, forming a liquid circulation. This flow direction can impact the rising air bubbles, causing them to deform and reducing their rising speed, increasing the possibility of bubble breaking in the liquid, and further promoting liquid mixing and temperature uniformity.

[0022] The system also includes a bubble-breaking mechanism, which includes a rectangular plate 13 horizontally fixed inside the dyeing box 1. The rectangular plate 13 has a rectangular opening 14. A slidable shaking net 15 is provided at the upper end of the rectangular plate 13. Two vertical plates 26 are symmetrically fixedly connected to the lower end of the shaking net 15. The opposite sides of the two vertical plates 26 are elastically connected to the corresponding inner wall of the dyeing box 1 through springs 28. Guide plates 27 are fixedly connected to the opposite sides of the two vertical plates 26. The upper ends of the two guide plates 27 are in contact with the lower end of the rectangular plate 13 and are slidably connected. An L-shaped abutment 23 is fixedly connected to the outer side of the rotating shaft 10. A connecting strip 24 is fixedly connected to the upper end of the shaking net 15. A round-headed abutment 25 is fixedly connected to the left side of the connecting strip 24. The round-headed abutment 25 cooperates with the L-shaped abutment 23. After the rotating shaft 10 rotates, it will drive the L-shaped abutment 23 to rotate. When the L-shaped abutment 23 contacts the round-headed abutment 25, it will push the round-headed abutment 25 and the shaking net 15 to move to the right, while compressing or stretching the corresponding spring 28. When the L-shaped abutment 23 separates from the round-headed abutment 25, the shaking net 15 moves to the left and resets under the action of the spring 28. This process is repeated, causing the shaking net 15 to shake continuously, breaking up the rising bubbles, making the bubbles smaller and more evenly distributed in the dye, and subsequently bursting more evenly in the dye, improving the uniformity of liquid flow.

[0023] The distribution plate 16 is equipped with a heating wire 18, and the dyeing chamber 1 is equipped with a temperature sensor 22 that works in conjunction with the heating wire 18. Together, they enable automatic heating. The temperature sensor 22 monitors the temperature of the liquid inside the dyeing chamber 1 in real time and feeds the signal back to the control system. When the temperature is lower than the set value, the control system activates the heating wire 18; when the temperature reaches the set value, the control system stops the heating wire 18, thus ensuring that the dyeing liquid remains within a suitable temperature range and improving dyeing quality.

[0024] In this invention, the drive motor 4 installed on the left side of the dyeing chamber 1 is started, and its output shaft drives the rotating shaft 10 extending into the dyeing chamber 1 to rotate. Multiple stirring rods 11 fixedly connected to the outside of the rotating shaft 10 rotate in the dyeing chamber 1, stirring the dyeing liquid, making the dye distribution more uniform, avoiding local concentrations that are too high or too low, thereby improving the dyeing quality.

[0025] When the rotating shaft 10 rotates, the rotating disk 20, which extends to the outside and is fixedly connected to it on its right end, rotates synchronously. The drive rod 32, which is eccentrically connected to the right side of the rotating disk 20, drives one of the piston plates 29 to reciprocate back and forth inside the piston cylinder 19. Since the two piston plates 29 are fixedly connected by the fixing rod 31, the two piston plates 29 move synchronously. When the rear piston plate 29 moves forward, it draws in gas from the top space of the dyeing tank 1 through the first one-way tube 21; when the rear piston plate 29 moves backward, it pushes the gas drawn in into the bottom space of the dyeing tank 1 through the second one-way tube 30, and finally into the interior of the distribution plate 16. The gas is evenly blown into the liquid at the bottom of the dyeing tank 1 through multiple distribution holes 17 at the top of the distribution plate 16, and the rising and bursting of the gas promotes the flow of the liquid.

[0026] When the front piston plate 29 moves backward, it draws liquid into the right cavity 8 through the first one-way pipe 21 on the front side; when the front piston plate 29 moves forward, it forces the drawn-in liquid into the filter box 12 through the second one-way pipe 30 on the front side. After being filtered in the filter box 12, the liquid enters the left cavity 8 through the connecting pipe 5 and finally flows out through the through hole 9, forming a liquid circulation. This allows the liquid to flow further while filtering out any fibers that may be generated in the dye solution, preventing them from affecting the quality of the finished product. This liquid flow direction can impact the rising air bubbles, causing them to deform, reducing their rising speed, increasing the possibility of bubble breaking in the liquid, and further promoting liquid mixing and temperature uniformity.

[0027] The rotation of the shaft 10 also drives the L-shaped abutment 23 fixed on its outer side to rotate. When the L-shaped abutment 23 contacts the round-headed abutment 25 on the left side of the connecting strip 24 at the upper end of the shaking net 15, it pushes the round-headed abutment 25 and the shaking net 15 to move to the right, while compressing or stretching the corresponding spring 28. When the L-shaped abutment 23 separates from the round-headed abutment 25, the shaking net 15 moves to the left and resets under the action of the spring 28. This process repeats, causing the shaking net 15 to shake continuously, breaking up rising bubbles, making the bubbles smaller and more evenly distributed in the dye, and subsequently bursting more evenly in the dye, improving the uniformity of liquid flow.

[0028] The distribution plate 16 is equipped with a heating wire 18, and the dyeing chamber 1 is equipped with a temperature sensor 22 that works in conjunction with the heating wire 18. The temperature sensor 22 monitors the temperature of the liquid in the dyeing chamber 1 in real time and feeds the signal back to the control system. When the temperature is lower than the set value, the control system starts the heating wire 18; when the temperature reaches the set value, the control system stops the heating wire 18, thereby ensuring that the dyeing liquid is always within a suitable temperature range, improving the dyeing quality. Because the liquid is in a flowing state, the temperature is relatively uniform, ensuring heat dissipation quality and preventing sedimentation.
