Description

Technical Field

[0001] The invention relates to the field of dyeing equipment, in particular to a dyeing processing device for chemical fibers. Background Art

[0002] Fiber is the basic unit of fabric. Whether it is natural fiber (such as cotton, wool, silk) or chemical fiber (such as polyester, nylon, acrylic), they are made into various types of fabrics such as woven fabrics, knitted fabrics and non-woven fabrics through spinning and weaving processes. Through dyeing, the fiber can present a variety of colors to meet different aesthetic concepts and fashion trends.

[0003] At present, there are many types of equipment used for fiber dyeing, such as supercritical carbon dioxide dyeing equipment, also known as atmospheric pressure waterless dyeing equipment, which uses other non-aqueous media (such as supercritical carbon dioxide, ionic liquids, etc.) under normal pressure to achieve fiber dyeing. This dyeing method can effectively solve the problems of large water consumption and large sewage discharge in traditional dyeing processes.

[0004] Existing supercritical carbon dioxide dyeing equipment includes carbon dioxide storage and supply system, dyeing reactor, dye adding system, separation and recovery system, etc. The carbon dioxide storage and supply system is used to control the storage of carbon dioxide and the output pressure of carbon dioxide. The dyeing reactor is the place for carbon dioxide dyeing. Multiple bobbins can be stacked inside. It is also equipped with a heating device to increase the temperature inside the reactor. The dye adding system can realize the storage and quantitative output of dyes. The separation and recovery system can separate carbon dioxide and fiber after dyeing is completed, and store carbon dioxide in a storage tank.

[0005] The supercritical carbon dioxide dyeing process and the devices required for use thereof can refer to the process method of supercritical carbon dioxide dyeing disclosed in a Chinese patent with publication number CN100359091C. The disclosed device includes a carbon dioxide storage tank, a dye kettle, and a dye kettle. The carbon dioxide provided by the carbon dioxide storage tank is cooled into liquid by a condensation system and then sent to a preheater through a carbon dioxide high-pressure pump; the preheater is connected to the dye kettle; the dye kettle sends the supercritical carbon dioxide that dissolves the dye to the dye kettle; after dyeing, the carbon dioxide liquid melted with the dye is sent back to the carbon dioxide storage tank through a separator and a second condenser in sequence. The device disclosed in the above patent can recover 100% of the unfixed dye during the dyeing process, and at the same time recycle the carbon dioxide as a dyeing medium, thereby achieving the purpose of saving water and dye resources and reducing environmental pollution.

[0006] After the tube yarn dyeing task is completed by supercritical carbon dioxide dyeing equipment or other high-temperature dyeing equipment, if the temperature and pressure are suddenly reduced and the tube yarn is taken out, the fiber structure of the tube yarn may change drastically, thereby affecting the dyeing effect. Therefore, the dyeing equipment is equipped with a circulating cooling water system to achieve the gradual cooling of the tube yarn. Although the above-mentioned cooling method can achieve the purpose of cooling the tube yarn, it has some defects, that is, its heat energy is directly wasted and not fully utilized. If the heat in the dyeing kettle can be recovered and used to heat the medium to be heated, it will save energy relatively. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0037] Example 1

[0038] like Figure 1 , Figure 2 As shown, in order to realize the heat recovery and utilization of the dyeing equipment and realize the cooling treatment of the bobbin yarn, this embodiment provides a new dyeing processing device, which includes a dyeing cylinder 1 and an airflow tube group 2 arranged in the dyeing cylinder 1. The air inlet and air outlet of the airflow tube group 2 are both arranged outside the dyeing cylinder 1, and the air outlet is connected to the air pump 11, and the output end of the air pump 11 is connected to the gas storage tank 12. Therefore, the low-temperature gas outside the dyeing cylinder 1 can be controlled by the operation control of the air pump 11 to enter the dyeing cylinder 1, and after the temperature is increased under the heating of the dyeing cylinder 1, it flows out of the dyeing cylinder 1 and is then stored in the gas storage tank 12. The high-temperature gas accumulated in the gas storage tank 12 can be used to heat other devices (such as carbon dioxide) to reduce the energy consumed by carbon dioxide heating. Due to the entry of low-temperature gas and the output of high-temperature gas, the cooling of the dyeing cylinder 1 is realized, and then the gradual cooling treatment of the bobbin yarn is realized, that is, when the cooling of the bobbin yarn is met, the heat recovery of the dyeing cylinder 1 is realized.

[0039] The dyeing jar 1 is an existing device, that is, the technical solution provided by this embodiment is to add an airflow pipe group 2 to the existing dyeing equipment. Here, the existing dyeing equipment (supercritical carbon dioxide dyeing equipment) is briefly introduced, which includes a carbon dioxide storage tank, a pressure regulator and a flow controller, a kettle body (the dyeing jar 1 in this embodiment), a dye storage container, a quantitative addition device, a separation device, a carbon dioxide recovery device, etc.

[0040] Carbon dioxide storage tank is a key equipment for storing liquid carbon dioxide, usually a pressure-resistant metal container. Its material should be able to withstand higher pressure, because carbon dioxide needs to maintain a certain pressure to maintain liquid state when stored. The pressure regulator is used to accurately control the pressure of the carbon dioxide output from the storage tank so that it reaches the pressure range required for the dyeing process. The flow controller can accurately adjust the flow of carbon dioxide according to the requirements of the dyeing process. For example, under different fiber types and dyeing depth requirements, the flow of carbon dioxide will be different, and refined operation can be achieved through the flow controller. Before carbon dioxide enters the dyeing reactor, it is necessary to heat carbon dioxide, such as the patent record of publication number CN100359091C, heat carbon dioxide by a heat exchanger, in this case, the high-temperature gas of the gas storage tank 12 can be circulated to the heat exchanger as a heat source, or first flow into the heating device and then flow into the heat exchanger, which can reduce the energy consumed by heating carbon dioxide.

[0041] The dyeing reactor (dyeing tank 1) is the core equipment of supercritical carbon dioxide dyeing. Its reactor body is usually made of high-strength stainless steel, such as 316L stainless steel, to resist the corrosion and high-pressure environment of supercritical carbon dioxide. The reactor body is a sealed structure and needs to have good sealing performance to prevent carbon dioxide leakage. It should also have good pressure resistance, and the design pressure is generally higher than the critical pressure of carbon dioxide, usually around 10-20MPa.

[0042] Dye storage containers are used to store solid or liquid dyes. Dye storage should be protected from moisture and oxidation to maintain the properties of the dye. For some environmentally sensitive dyes, the storage container may also need to have special protection functions, such as light protection, inert gas protection, etc.

[0043] The quantitative addition device is a key part to ensure dyeing uniformity and color accuracy. The dye is added to the reactor at a predetermined amount and speed through a precision metering pump or syringe and other equipment. For example, the amount of dye added is accurately calculated based on factors such as fiber weight and dyeing depth requirements, and the error is controlled within a small range, generally around ±1%.

[0044] After dyeing is completed, the carbon dioxide needs to be separated from the dyed fibers. The separation device usually uses pressure difference or temperature change to achieve this. For example, by reducing the pressure, supercritical carbon dioxide is turned back into gas and escapes from the fiber. At the same time, it is also necessary to prevent the fiber from being carried out during the separation process, and a filtering device is generally installed at the outlet. The carbon dioxide recovery device includes a compressor, a dryer, and a cooler. The compressor compresses the gaseous carbon dioxide back to a liquid state, the dryer removes moisture and impurities in the carbon dioxide, and the cooler further cools the carbon dioxide, returning it to a liquid state and storing it in a storage tank.

[0045] like Figure 3 As shown, in order to be able to introduce external low-temperature gas into the dyeing tank 1 through the air flow pipe group 2 and facilitate the high-temperature gas to flow out of the dyeing tank 1, the air flow pipe group 2 includes an air inlet pipe 21 and an air receiving pipe 22. The air inlet pipe 21 is arranged at the bottom of the dyeing tank 1, and the air inlet end is arranged on the outside of the dyeing tank 1. The air receiving pipe 22 is arranged at the top of the dyeing tank 1, and the air outlet end of the air receiving pipe 22 is arranged on the outside of the dyeing tank 1. At the same time, the air outlet end of the air receiving pipe 22 is connected to the air pump 11. Therefore, after dyeing is completed, by controlling the solenoid valves installed in the air inlet pipe 21 and the air receiving pipe 22 to work, the air inlet pipe 21 and the air receiving pipe 22 are made unobstructed. Under the action of the air pump 11, the external gas can be introduced into the dyeing tank 1 from the air inlet pipe 21 and circulate from the bottom to the top of the dyeing tank 1. In this process, the gas problem can be increased under the action of the dyeing tank 1. After the heated gas enters the air receiving pipe 22, it can be output from the dyeing tank 1 and stored in the gas storage tank 12.

[0046] like Figure 3 As shown, in order to achieve the cooling of the bobbin yarn, a plurality of dispersion tubes 23 may be arranged above the air inlet pipe 21, and the gas outlets of the dispersion tubes 23 all point to the center of the dyeing vat 1, that is, the low-temperature gas output from the dispersion tubes 23 can flow to the side of the bobbin yarn, thereby facilitating the faster cooling of the bobbin yarn.

[0047] like Fig.12 As shown, in order to stably install the air inlet pipe 21 in the dyeing tank 1, a support plate 41 is provided at the bottom of the dyeing tank 1, and the end of the support plate 41 is connected to the dyeing tank 1. A third buckle arc plate 46 is provided above the support plate 41. The central angle of the third buckle arc plate 46 is greater than 180° and is sleeved on the air inlet pipe 21, thereby limiting the air inlet pipe 21 to be stably arranged above the support plate 41.

[0048] like Fig.12As shown, in order to make the third snap-on arc plate 46 stably and detachably arranged above the support plate 41, a plurality of through holes 48 are arranged on the support plate 41, and an insert plate 47 is arranged under each third snap-on arc plate 46. The insert plate 47 passes through the through hole 48, and a bolt is passed through the bottom. Therefore, under the action of the bolt, the insert plate 47 can be stably installed on the support plate 41, and at the same time, it is convenient to remove the insert plate 47 according to needs.

[0049] like Figure 3 , Figure 4 As shown, in order to stably install the dispersion tubes 23, a support ring plate 24 is provided on the outside of the plurality of dispersion tubes 23, the outer diameter of the support ring plate 24 is less than or equal to the inner diameter of the dyeing jar 1, and the support ring plate 24 is connected to the dyeing jar 1. A plurality of first buckle arc plates 242 are connected and provided on the inner side of the support ring plate 24 through a first connecting plate 241, and the plurality of first buckle arc plates 242 are distributed and provided along the circumferential direction of the support ring plate 24. The center angle of the first buckle arc plate 242 is greater than 180°, and the number of the first buckle arc plates 242 is equal to the number of the dispersion tubes 23, therefore, the plurality of dispersion tubes 23 are respectively provided through the plurality of first buckle arc plates 242, therefore, when the support ring plate 24 is stably installed, the plurality of dispersion tubes 23 are stably installed in the dyeing jar 1.

[0050] like Figure 5 As shown, similarly, in order to stably install the air collecting pipe 22 on the top of the dyeing tank 1, a plurality of connecting frames 26 are provided on the air collecting pipe 22, and the connecting frames 26 are connected to the dyeing tank 1. Therefore, under the action of the connecting frames 26, the air collecting pipe 22 is stably installed on the dyeing tank 1.

[0051] like Figure 6 As shown, specifically, the connecting frame 26 includes a connecting plate 261, a second connecting plate 263 and a second snap-on arc plate 264, the central angle of the second snap-on arc plate 264 is greater than 180°, and is sleeved on the air collecting pipe 22, one end of the second connecting plate 263 is connected to the second snap-on arc plate 264, and the other end is installed in the notch 262 of the connecting plate 261 by bolts, and the end of the connecting plate 261 away from the second snap-on arc plate 264 is connected to the dyeing tank 1, and after the second snap-on arc plate 264 is sleeved on the air collecting pipe 22, the connecting plate 261 and the second connecting plate 263 cooperate to support the air collecting pipe 22 to be stably placed.

[0052] like Figure 5 As shown, in addition, a plurality of gas hoods 25 can be arranged below the air collecting pipe 22, and the gas is collected by the gas hoods 25 and enters the air collecting pipe 22. The top of the gas hood 25 is connected with an external threaded pipe 251, which is threaded and connected to the air collecting pipe 22.

[0053] Example 2

[0054] like Figure 2 , Figure 7 As shown, in order to facilitate the cooling of the bobbin yarn, make the bobbin yarn have more contact with the low-temperature gas, and at the same time make the bobbin yarn stably placed in the dyeing tank 1 to complete the dyeing process, a supporting frame 3 is also provided on the inner side of the dyeing tank 1, and the supporting frame 3 is arranged on the inner side of the airflow tube group 2. Therefore, under the action of the supporting frame 3, the bobbin yarn is located on the inner side of the dispersion tube 23, which facilitates the low-temperature gas to flow to the side of the bobbin yarn.

[0055] like Figure 8 As shown, specifically, the support frame 3 includes a center rod 31, a bottom plate 33 and a plurality of limiting rods 32. The bottom plate 33 is set as a polygonal structure, the bottom of the center rod 31 is connected to the center of the bottom plate 33, and a U-shaped ring 311 connected to a hook is fixedly set on the top, so that the hook of the lifting equipment can be connected to the U-shaped ring 311, and then the entire support frame 3 and the bobbin can be controlled to move under the support of the center rod 31, so as to facilitate the support frame 3 and the bobbin to enter and exit the dyeing tank 1. The plurality of limiting rods 32 are respectively arranged at each end corner of the bottom plate 33, so that a plurality of bobbin yarns stacked up and down are sleeved on the limiting rods 32, so that the bobbin yarns can be stably placed relative to the bottom plate 33.

[0056] like Fig.11 As shown, in order to limit the stable installation of the bobbin yarn relative to the limiting rod 32, a threaded structure 321 is arranged on the top of the limiting rod 32, and an internal threaded tube 324 is threadedly sleeved at the threaded structure 321, and a pressure plate 322 is arranged below the internal threaded tube 324, and a spring 323 in a compressed state is arranged between the pressure plate 322 and the internal threaded tube 324. Therefore, after multiple bobbin yarns are stacked and sleeved on the outside of the limiting rod 32, the pressure plate 322 is placed on the top of the bobbin yarn, and then pressure is applied to the spring 323 through the internal threaded tube 324, so that the pressure plate 322 presses against the top of the bobbin yarn, thereby limiting the stable placement of the bobbin yarn.

[0057] like Figure 8 As shown, in order to control the rotation of the bobbin yarn, the bottom of the limiting rod 32 is connected through the bottom plate 33 through a bearing, and the bottom of the limiting rod 32 is fixedly provided with a support plate with a structure communicating with the pressure plate 322, and the bobbin yarn is arranged between the support plate and the pressure plate 322. Therefore, when the limiting rod 32 rotates, the bobbin yarn rotates synchronously, which facilitates the contact between different parts of the side wall of the bobbin yarn and the low-temperature gas.

[0058] like Figure 1 , Figure 2 , Figure 7 , Fig.10As shown, in order to control the rotation of the bobbin yarn, a motor 13 is arranged above the dyeing jar 1, and a transmission shaft 14 is arranged below the power output shaft of the motor 13 through a coupling, and an end column 15 is fixedly arranged at the bottom of the transmission shaft 14, and a slot 16 is arranged on the bottom surface of the end column 15. The slots 16 are arranged crosswise, and the top of the U-shaped ring 311 can be inserted into the slot 16, that is, after the bobbin yarn and the supporting frame 3 are placed in the dyeing jar 1, and the cover of the dyeing jar 1 is closed, the U-shaped ring 311 is inserted into the slot 16, then when the motor 13 is working, the center rod 31 can be driven to rotate, so the center rod 31 is fixedly connected to the bottom plate 33, and multiple limiting rods 32 revolve around the center rod 31. The ends of the transmission shaft 14 and the center rod 31 adjacent to each other can also be respectively provided with two parts of a magnetic coupling, so as to realize transmission under the action of magnetic force.

[0059] like Fig. 9 , Fig.12 As shown, during the revolution of the limiting rod 32, in order to realize the self-rotation of the limiting rod 32, a wheel body 34 is sleeved on the end of the limiting rod 32 protruding from the bottom plate 33. At the same time, a fixed ring plate 43 is provided above the support plate 41 through bolts, and multiple wheel bodies 34 are distributed on the outside of the fixed ring plate 43 and contact the fixed ring plate 43. Therefore, the wheel body 34 can rotate relative to the fixed ring plate 43 under the action of friction, thereby driving the limiting rod 32 to rotate, providing convenience for adjusting the direction of the bobbin yarn. In order to increase the friction between the wheel body 34 and the fixed ring plate 43, mutually matching concave-convex structures can be provided on the side walls of the wheel body 34 and the fixed ring plate 43, or an anti-slip layer can be provided on the side walls.

[0060] like Fig.12 As shown, in order to stably set the bracket 3 on the support plate 41, a limiting ring plate 44 is fixedly set in the middle above the support plate 41, and a thrust bearing 45 is set on the inner side of the limiting ring plate 44. The top surface of the thrust bearing 45 is higher than the top surface of the fixed ring plate 43 and contacts the bottom plate 33. Therefore, under the action of the thrust bearing 45, not only the bottom plate 33 is stably placed relative to the support plate 41, but also support is provided for the rotation of the bottom plate 33. Because the thrust bearing 45 includes a shaft ring, a seat ring, a ball, etc., the seat ring contacts the support plate 41, and the shaft ring can be fixedly installed on the bottom plate 33.

[0061] like Fig.12 , Fig.13As shown, in order to mix the dye and carbon dioxide when dyeing the bobbin yarn, a stirring blade 42 is arranged below the support plate 41. The central axis 49 of the stirring blade 42 is connected through the bracket through a bearing, and the top is arranged through the central hole of the support plate 41. A magnetic coupling 312 is arranged on the top of the central axis 49. The magnetic coupling 312 is connected to the end of the center rod 31 protruding from the bottom plate 33 and is located on the inner side of the thrust bearing 45. Therefore, when the center rod 31 rotates, the stirring blade 42 can be driven to rotate to achieve material mixing.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
