Description

Technical Field

[0001] The present application relates to the technical field of cheese dyeing, and in particular to a cheese negative pressure dyeing device and method. Background Art

[0002] Cheese yarn is widely used in the textile industry. Cheese yarn is produced in white color. When used in production, it is usually necessary to dye the cheese yarn. The cheese yarn dyeing method is to put the cheese yarn into the dyeing cabin, clean and bleach the cheese yarn, add the dyeing liquid after the cheese yarn is cleaned, and use the circulation pump to flush the cheese yarn to improve the permeability of the dye and the yarn to achieve full dyeing. Because during the dyeing process, a large number of bubbles will be adsorbed on the surface of the cheese yarn and the surface of the yarn fiber, which hinders the full combination of the dye and the cheese yarn fiber, resulting in uneven dyeing and the appearance of pitting. In particular, in order to reduce pollution to the environment, an ultra-high pressure salt-free dyeing process is adopted. During the ultra-high pressure fixation process, the bubbles in the yarn fibers will explode under the action of ultra-high pressure, affecting the combination of dye and yarn fibers, thereby making the yarn dyeing spots more obvious. Therefore, a dyeing equipment is needed to use negative pressure to extract the tiny bubbles between the dye and yarn fibers during the dyeing process of the cheese yarn, ensuring that the dyed yarn is evenly dyed, reducing spots, and improving the dyeing quality.

When dyeing cheese yarn, the cheese yarn is mounted on the cheese yarn dyeing rack, the dye is prepared in the dye matching device, and the dye matching device transports the dye to the water adding device. When the water adding device adds water to the dyeing chamber, the dyeing liquid is added at the same time. When the water in the dyeing chamber reaches a specified liquid level, the water adding device controls the water to circulate in the dyeing chamber. During the water circulation process, the dyeing liquid is continuously replenished, so that the dyeing liquid mixed with water maintains a certain concentration, thereby making the dyeing more uniform. 2. A vacuum pump connecting pipe is installed on the dye distribution device, and the vacuum pump connecting pipe is connected to the vacuum pump. When the dyeing liquid is completely added, the dyeing solution in the dyeing cabin is controlled to circulate for a period of time through the water adding device, and the dye matching device is evacuated by the vacuum pump to discharge the gas in the dyeing cabin, so that a negative pressure is generated in the dyeing cabin, thereby discharging the gas in the cheese yarn, thereby reducing the bubbles inside the cheese yarn, and allowing the dyeing solution to enter the cheese yarn, thereby reducing the occurrence of pitting caused by the presence of bubbles inside the cheese yarn.

In ultra-high pressure salt-free dyeing, the tiny bubbles in the cheese and cheese fibers are discharged through negative pressure, thereby reducing the precipitation of bubbles during the ultra-high pressure dyeing process and further reducing the generation of cheese spots.

[0016] 5. Under the action of negative pressure, tiny bubbles in the cheese and cheese fibers can be discharged to prevent bubbles from blocking the flow of dye solution and causing uneven dyeing. The vacuum negative pressure allows the dye solution to quickly penetrate into the yarn, improving dyeing efficiency. 6. In a negative pressure environment, bubbles on the surface of the cheese yarn and the cheese yarn fiber surface are discharged, so that the dyeing liquid can better enter the interior of the cheese yarn, making the cheese yarn dyed uniformly inside and outside, thereby improving the quality of the cheese yarn.

[0019] The following is combined with Figure 1 -Attached Figure 19 , further details of this application are given.

At this time, water is added to the dyeing cabin 1 through the water adding device 3, and hydrogen peroxide is added to the dyeing cabin 1 from the dye matching device 6. When the water is full, the water adding device 3 controls the water to circulate in the dyeing cabin 1 to rinse the cheese, thereby removing impurities and mixed colors in the cheese. After the rinsing is completed, the water is discharged from the dyeing cabin 1. Thus, impurities on the surface of the cheese are discharged, thereby reducing the generation of pitting. After the rinsing water in the dyeing chamber 1 is drained, a dyeing liquid is prepared according to the required color in the dye matching device 6. After the dyeing liquid is prepared, the dyeing liquid is transported to the water adding device 3 through the dye delivery pipe 65. During the water adding process, the dyeing liquid is mixed with water and then transported to the dyeing chamber 1 to dye the cheese yarn. This can effectively prevent the dyeing liquid concentration from being too high, which causes uneven dyeing of the cheese yarn. When the water is added to the specified level, the water adding device 3 controls the water to circulate in the dyeing chamber 1. At this time, dyeing liquid can still be added to the water adding device 3 to replenish the dyeing liquid absorbed by the cheese yarn, so that the dyeing liquid maintains a certain concentration and makes the dyeing more balanced. When the dyeing liquid in the dye matching device 6 is added, the water adding device 3 controls the solution in the dyeing chamber 1 to continue to circulate, so that the cheese yarn is fully dyed; After a period of circulation, the vacuum pump evacuates the dye matching device 6 and exhausts the gas in the dyeing chamber 1 through the negative pressure pipe 67 installed at the upper end of the dyeing chamber 1. Under the action of negative pressure, the gas inside the cheese is discharged, and the dyeing solution can further penetrate into the cheese and be adsorbed on the cheese; thus, the dyeing solution is more evenly adsorbed on the cheese, thereby reducing the pitting on the cheese; In a negative pressure environment, tiny bubbles on the cheese surface and cheese fibers can be quickly discharged, and the dyeing liquid can be quickly combined with the cheese, thereby reducing the cheese soaking time and improving the dyeing efficiency; The negative pressure pipe 67 is arranged at the upper end of the dyeing chamber 1. When the negative pressure is pumped into the dyeing chamber 1, the liquid level drop of the dyeing solution in the dyeing chamber 1 can be effectively reduced, so that the cheese yarn on the upper layer in the dyeing chamber 1 can also be fully dyed.

[0021] After the dyeing liquid is adsorbed, the cheese and cheese dyeing rack 4 are transferred to the ultrahigh pressure dyeing equipment. After ultrahigh pressure treatment, the dyeing liquid molecules are fully combined with the cheese molecules, thereby achieving color fixation and reducing the use of salt.

The water inlet pipe 33 is located at the center and edge of the lower end of the dyeing chamber 1. The dye delivery pipe 65 is connected to the water pump 31. During the water addition process, the water inlet valve 331 is opened, and water enters from the water inlet pipe 33. The water outlet pipe 34 is controlled by the worm gear four-way ball valve 36 to be connected to the water inlet 11 near the center. At this time, the electric butterfly valve 12 on the water inlet 11 near the edge of the U-shaped water pipe 35 is closed, and water enters the dyeing chamber 1 from the water inlet 11 at the center. The dye is transported to the water pump 31 through the dye delivery pipe 65. The dyeing liquid is input into the dyeing chamber 1 from the water inlet 11 near the center. At this time, dyeing begins in the dyeing chamber 1; dyeing is carried out from the inside of the cheese to the outside. When the worm gear four-way ball valve 36 rotates 90 degrees to control the water outlet pipe 34 to be connected to the water inlet 11 near the edge of the dyeing chamber 1, the electric butterfly valve 12 on the water inlet 11 near the center is closed, and then the electric butterfly valve 12 on the water inlet 11 near the edge is opened. At this time, water enters the dyeing chamber 1 from the water inlet 11 near the edge, and dyeing is carried out from the outside of the cheese to the inside of the cheese.

At this time, dyeing is carried out from the outside of the cheese to the inside of the cheese. When the worm gear four-way ball valve 36 rotates 90 degrees, the worm gear four-way ball valve 36 connects the water outlet pipe 34 with the water inlet 11 near the center, and water enters the dyeing chamber 1 from the water inlet 11 near the center, is discharged from the water inlet 11 near the edge of the dyeing chamber 1, and then enters the water pump 31.

The dye delivery pipe 65 is connected to the water pump 31, and the dyeing liquid and water are fully mixed by the water pump 31. During the water circulation process, the dyeing liquid can be continuously added to the water, so that the concentration of the dyeing solution can be maintained in a certain range, thereby making the dyeing more balanced.

During the water circulation process, the electromagnetic heater 332 continues to heat the dyeing solution to maintain a constant temperature of the dyeing solution; when the dyeing is completed, the dyeing solution needs to be discharged. At this time, the condenser 333 is opened, and the water circulation mode is turned on. The condenser 333 is used to cool down the dyeing solution to reduce the temperature. When the dyeing solution temperature drops to a safe range, it is discharged. This can effectively prevent the high-temperature dyeing solution from damaging the surrounding environment, and does not require a large amount of water to absorb the temperature of the discharged dyeing solution, reducing the practicality of water, while speeding up the cooling speed and improving production efficiency.

During the working process of the water circulation, when the water pump 31 starts working, the dyeing solution enters the dyeing cabin 1 from the water inlet 11 at the center position, and then is discharged from the water inlet 11 near the edge of the dyeing cabin 1 into the water inlet pipe 33, and then enters the water pump 31 to realize water circulation. When the valve stem 363 is rotated to control the ball 362 to rotate 90 degrees, the water inlet 11 near the edge of the dyeing chamber 1 is connected to the water outlet pipe 34 set at the water outlet end of the water pump 31, and the water inlet 11 at the center position is connected to the water inlet pipe 33. Therefore, during the working process of water circulation, when the water pump 31 starts working, the dyeing solution enters from the water inlet 11 at the edge of the dyeing chamber 1, is discharged from the water inlet 11 near the center position, enters the water inlet pipe 33, and then enters the water pump 31, realizing water circulation.

A first water channel 431 is retained between the support rod 42 and the porous sleeve 43. When the dyeing solution is input into the dyeing chamber 1, the dyeing solution can pass through the first water channel 431. When the water rises to the top and is resisted by the lower pressure plate 45, water pressure is generated. At this time, the dyeing solution can pass through the porous sleeve 43 and dye the cheese from the inside out. When the cheese yarn is dyed from the outside to the inside, the dyeing liquid can be input into the lower side of the frame 41 through the first water guide channel 431 .

A second water guide channel 416 is left between the support rod 42 and the water guide ring seat 414; the second water guide channel 416 corresponds to the first water guide channel 431.

[0027] When water enters from the water inlet 11 provided at the edge of the dyeing chamber 1, the dyeing solution enters the dyeing chamber 1 through the water guide hole 411. At this time, the dyeing solution enters the dyeing chamber 1 from the outside of the cheese yarn to the inside of the cheese yarn, and finally enters the first water guide channel 431, then enters the second water guide channel 416, and enters the water inlet 11 at the center of the dyeing chamber 1 through the water guide channel 413, and is discharged from the water inlet 11 at the center of the dyeing chamber 1.

At this time, the cheese dyeing rack 4 in the dyeing cabin 1 can be lifted out by the crane or the cheese dyeing rack 4 can be placed in the dyeing cabin 1; A counterweight 76 is fixed to the end of the L-shaped turning frame 72 away from the sealing cover 5. The lever principle can make the turning of the sealing cover 5 more convenient, while reducing the pulling force required during the turning process, reducing the wear of the traction cylinder 75, and extending the service life of the traction cylinder 75. After the cheese dyeing frame 4 is placed in the dyeing chamber 1, the L-shaped turning frame 72 is turned over by the traction cylinder 75, and the limiting protrusion 51 fixed around the sealing cover 5 is aligned with the limiting groove 151 on the U-shaped limiting ring 15. The lifting cylinder 73 controls the sealing cover 5 to move downward, and the hollow rotating platform reducer 74 controls the sealing cover 5 to rotate, so that the limiting protrusion 51 is stuck on the U-shaped limiting ring 15. Under the action of the sealing gasket, the sealing cover 5 and the dyeing chamber 1 form a sealing structure; After the sealing cover 5 and the dyeing chamber 1 form a sealing structure, the sealing cover 5 and the dyeing chamber 1 are locked by the locking assembly 52, so that the dyeing equipment can work more stably.

[0029] Reference Figure 12 、 Figure 13 、 Figure 14 A locking assembly 52 is fixed on the side of the dyeing cabin 1 to lock the dyeing cabin 1 and the sealing cover 5 together. The locking assembly 52 includes a pressure balance pipe 521 fixed to the side of the dyeing cabin 1, a pressure balance valve 522 is installed on the pressure balance pipe 521, and a gear 523 is installed on the pressure balance valve 522.

A locking nose 528 is fixed to the outer edge of the sealing cover 5, and the locking nose 528 cooperates with the locking seat 527. When the sealing cover 5 and the dyeing chamber 1 are closed, the locking cylinder 524 extends, driving the gear 523 to rotate through the rack 525, so that the pressure balancing valve 522 installed on the pressure balancing pipe 521 is closed. At the same time, the locking bolt 526 passes through the locking seat 527 and the locking nose 528, so that the sealing cover 5 cannot move relative to the dyeing chamber 1, thereby locking the closed dyeing chamber 1 and the sealing cover 5 to form a sealed structure. When dyeing is completed, the dyeing chamber 1 needs to be opened. The locking cylinder 524 is shortened, and the rack 525 drives the gear 523 to rotate, opening the pressure balance valve 522. Gas can enter the dyeing chamber 1 from the pressure balance pipe 521, so that the negative pressure environment in the dyeing chamber 1 is quickly balanced with the external air pressure, thereby facilitating the opening of the sealing cover 5 and the dyeing chamber 1. If the dyeing chamber 1 is under high pressure, the gas can be quickly discharged from the pressure balance pipe 521 to balance the pressure in the dyeing chamber 1 with the external pressure.

[0030] An air pressure balance pipe 529 is installed on the pressure balance pipe 521. The air pressure balance pipe 529 is connected to an air pump for inputting air into the pressure balance pipe 521. An air valve is installed on the air pressure balance pipe 529. In order to quickly balance the air pressure in the dyeing cabin 1 with the external air pressure, the air valve on the air pressure balance pipe 529 can be opened to input air to accelerate the air pressure balance in the dyeing cabin 1; When the pressure balance valve 522 is closed, gas can be added to the dyeing cabin 1 through the pressure balance pipe 529 by an air pump to control the air pressure in the dyeing cabin 1 .

[0033] After adding water into the color matching chamber 61, the dye is mixed and added into the color matching chamber 61. The stirring motor 621 drives the stirring shaft 622 to rotate, so that the dye and water are fully mixed to form a dye liquid. The dye liquid is connected to the water pump 31 through the dye delivery pipe 65. During the process of adding water, the dye liquid is input into the dyeing chamber 1. One end of the negative pressure tube 67 is connected to the color matching chamber 61, and the other end is connected to the upper end of the dyeing chamber 1. When the dyeing liquid enters the negative pressure tube 67 during the negative pressure pumping process, it can be discharged into the color matching chamber 61, which can effectively prevent the dyeing liquid from entering the vacuum pump and causing damage to the vacuum pump. A color matching pump 68 is fixed to one end of the dye delivery pipe 65 connected to the water pump 31. The color matching pump 68 is used to transport the water in the dyeing cabin 1 to the color matching bin 61. The color matching pump 68 transports the water in the dyeing cabin 1 to the color matching bin 61 to complete the color matching and then transports it back to the dyeing cabin 1, which can better stabilize the bath ratio, thereby effectively preventing color differences caused by changes in the bath ratio and further improving the dyeing quality.

[0034] Reference Figure 2 、 Figure 12 A liquid discharge pipe 13 and a liquid level monitoring assembly 14 are provided on the side of the dyeing chamber 1; an electromagnetic sealing valve 131 is installed on the liquid discharge pipe 13; the upper end of the liquid discharge pipe 13 is connected to the upper end of the dyeing chamber 1. When the liquid level in the dyeing chamber 1 is too high, it can be discharged from the liquid discharge pipe 13. An electromagnetic sealing valve 131 is installed on the liquid discharge pipe 13. The electromagnetic sealing valve 131 is controlled to control the liquid discharge pipe 13 to be blocked or opened. When negative pressure is drawn into the dyeing chamber 1, the liquid discharge pipe 13 is blocked by the electromagnetic sealing valve 131; when the liquid level in the dyeing chamber 1 is too high, the electromagnetic sealing valve 131 is opened to discharge excess dyeing solution; under normal circumstances, the electromagnetic sealing valve 131 is in a closed state; The liquid level monitoring assembly 14 includes a liquid level monitoring tube 141. The upper end of the liquid level monitoring tube 141 is connected to the upper end of the dyeing chamber 1, and the lower end of the liquid level monitoring tube 141 is connected to the lower end of the U-shaped water pipe 35. Using the principle of a coupling, the liquid level in the dyeing chamber 1 can be seen through the liquid level monitoring tube 141. When the liquid level reaches a set height, it is convenient to stop adding water in time. When the liquid level is too high, the excess is discharged through the liquid discharge pipe 13. A drain pipe 351 is provided at the lower end of the U-shaped water pipe 35. The drain pipe 351 is connected to the liquid level monitoring pipe 141. A first pneumatic drain valve 352 is provided at the end of the drain pipe 351 away from the liquid level monitoring pipe 141, and a second pneumatic drain valve 353 is provided at the end of the drain pipe 351 close to the liquid level monitoring pipe 141. Under normal circumstances, the second pneumatic drain valve 353 is open and the first pneumatic drain valve 352 is closed. The drain pipe 351 is connected to the liquid level monitoring pipe 141, and the liquid level and color of the dyeing solution in the dyeing chamber 1 can be observed through the liquid level monitoring pipe 141. When the first pneumatic drain valve 352 is opened, the liquid in the dyeing chamber 1 can be discharged through the drain pipe 351, and the dyeing solution can be sampled and tested to check the color and concentration of the dye. The liquid in the dyeing chamber 1 can be discharged through the drain pipe 351, which can reduce the residual dyeing solution in the dyeing chamber 1 and the U-shaped water pipe 35 and reduce the influence of the dyeing solution on the second dyeing; A water circulation pump 142 is provided on the liquid level monitoring pipe 141. The water circulation pump 142 is used to circulate the liquid in the dyeing chamber 1 up and down. When the water adding device 3 stops working, the water circulation pump 142 is turned on. The water circulation pump 142 transports the dyeing liquid at the bottom to a higher place, thereby promoting water circulation and effectively preventing the dyeing liquid from settling and causing dyeing differences between the upper and lower layers of the cheese yarn. Before vacuuming, the electric butterfly valve 12 on the water inlet 11 is closed, and other valves are closed to form a sealed structure in the dyeing cabin 1. At this time, the water circulation pump 142 is turned on to allow the dyeing liquid inside the water adding device 3 to enter the dyeing cabin 1, increasing the liquid level inside the dyeing cabin 1. This can effectively prevent the discharge of bubbles on the surface of the cheese yarn and yarn fiber during the negative pressure extraction process, causing the liquid level of the dyeing liquid inside the dyeing cabin 1 to drop, so that the upper cheese yarn is not immersed in the dyeing liquid, resulting in the upper cheese yarn failing to fully contact with the dyeing liquid, resulting in the phenomenon of pitting on the upper cheese yarn.

The breathing valve 81 is used to balance the air pressure, so that the air pressure in the dyeing cabin 1 is balanced, and the safety valve 82 is used to prevent high pressure; During the process of adding and draining water into the dyeing chamber 1, the air pressure in the dyeing chamber 1 is balanced by the breathing valve 81. This effectively prevents the air pressure in the dyeing chamber 1 from being too high, which would affect the water adding efficiency. When dyeing is completed, the liquid in the dyeing chamber 1 needs to be drained. At this time, the breathing valve 81 can balance the negative pressure in the dyeing chamber 1, so that the liquid in the dyeing chamber 1 can be quickly drained. When the pressure in the dyeing chamber 1 rises sharply, the safety valve 82 opens under the action of high pressure, and the gas is quickly discharged, effectively preventing the cloud dyeing chamber 1 from exploding due to excessive pressure inside; A protective sealing valve 84 is fixed to one end of the safety protection tube 83 near the dyeing cabin 1. When the dyeing cabin 1 is pumped with negative pressure, the protective sealing valve 84 is closed. At this time, the breathing valve 81 and the safety valve 82 no longer work, thereby generating negative pressure in the dyeing cabin 1, discharging the gas inside the cheese yarn, and allowing the dyeing liquid to enter the cheese yarn and be more evenly adsorbed on the cheese yarn.

[0036] The breathing valve 81 can effectively reduce the dust in the air from entering the dyeing chamber 1 and affecting the dyeing effect.
