Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester filament processing technology, specifically to a high-efficiency and energy-saving dyeing device for polyester filament. Background Technology
[0002] Polyester filament is a type of polyester fiber that is commonly used in clothing manufacturing because it is resistant to chemicals and can withstand frequent washing.
[0003] When dyeing polyester yarn, a dyeing device is required. However, the dyeing device does not have the function of preventing sedimentation of the dyeing solution in the dyeing tank. As a result, the dyeing solution will separate into layers in the dyeing tank, causing uneven dyeing of polyester yarn. This requires secondary dyeing of polyester yarn and greatly reduces the dyeing efficiency of polyester yarn. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a high-efficiency and energy-saving dyeing device for polyester yarn, which has advantages such as preventing sedimentation of the dyeing solution and solving the problem of sedimentation and stratification in the dyeing solution.
[0005] This utility model discloses a high-efficiency and energy-saving dyeing device for polyester yarn, comprising a dyeing box, a dyeing tank on the right side of the inner cavity of the dyeing box, sliding sleeves on both sides of the inner cavity of the dyeing tank, guide rods rotatably connected to both sides of the bottom of the inner cavity of the dyeing tank, an anti-sedimentation component in the inner cavity of the dyeing tank, the anti-sedimentation component including a water pump, the water pump being fixedly connected to the front of the dyeing box, a suction pipe connected to the input end of the water pump, one end of the suction pipe being connected to the dyeing tank in the dyeing box, an outlet pipe connected to the output end of the water pump, a diversion pipe extending through and into the inner cavity of the dyeing tank at one end of the outlet pipe, a connecting pipe connected to the bottom of the diversion pipe, a drain pipe connected to the bottom of the connecting pipe, and a drain hole on the surface of the drain pipe. When it is necessary to prevent sedimentation and stratification of the dyeing solution in the dyeing tank, the water pump first operates, and the dyeing solution in the dyeing tank is transferred to the suction pipe, and then drained through the suction pipe... The dyeing solution is transferred to a water pump, which then transfers it to an outlet pipe. From there, it's transferred to a distribution pipe, which in turn distributes it to multiple connecting pipes. Finally, it's transferred to a drain pipe. The drain hole in the drain pipe allows for high-pressure discharge of the dyeing solution, ensuring its flow within the dyeing tank. This high-pressure discharge also promotes rolling within the dyeing tank, preventing sedimentation and stratification of the dyeing solution during polyester dyeing. This results in uneven dyeing of the polyester yarn, requiring secondary dyeing and significantly reducing dyeing efficiency. When dyeing polyester yarn is needed, it is transported separately through two sliding sleeves and guided into the dyeing tank by two guide rods.
[0006] The present invention relates to a high-efficiency and energy-saving dyeing device for polyester yarn, wherein a fixing plate is fixedly sleeved on the surface of the diversion tube, and the inner cavity of the fixing plate is fixedly connected to the dyeing tank by fixing bolts. The fixing plate and fixing bolts can fix the diversion tube, thus improving the diversion tube's performance during use and preventing the diversion tube from shaking and causing unstable flow.
[0007] This utility model discloses a high-efficiency and energy-saving dyeing device for polyester yarn. The dyeing chamber has a drain trough on its left side, and an opening at the top of the left side of the drain trough. Two drain rollers are rotatably connected to the top of the drain trough. An outlet is located at the bottom of the left side of the dyeing chamber, and the outlet's inner cavity communicates with the drain trough's inner cavity. The dyed polyester yarn is transferred to the drain trough, where it is positioned on opposite sides of the two drain rollers. As the yarn is conveyed through the opening, the two drain rollers drain excess dyeing liquid from the yarn. The drained dyeing liquid falls into the drain trough and is periodically discharged through the drain outlet for reuse.
[0008] This utility model discloses a high-efficiency and energy-saving dyeing device for polyester yarn. The dyeing box is provided with a lid on the top, and handles are provided on both sides of the top of the lid. The surface of the handles is covered with anti-slip rubber sleeves. The handles and anti-slip rubber sleeves make it easy to pick up and put down the lid when the dyeing box needs to be opened and closed, avoiding the inconvenience of picking up and putting down the lid.
[0009] The present invention relates to a high-efficiency and energy-saving dyeing device for polyester yarn, wherein the bottom of the dyeing box is provided with an anti-slip pad, and the bottom of the anti-slip pad is provided with an anti-slip thread.
[0010] The present invention relates to a high-efficiency and energy-saving dyeing device for polyester yarn, wherein the number of connecting tubes is seven, and four connecting tubes are equidistantly connected to the inner cavity of the diversion tube.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. When it is necessary to prevent sedimentation and stratification of the dyeing solution in the dyeing tank, this utility model first operates a water pump. The dyeing solution in the dyeing tank is transferred to the suction pipe, then to the water pump, and finally to the outlet pipe. The outlet pipe then transfers the dyeing solution to the distribution pipe, which in turn transfers it to multiple connecting pipes. Finally, the connecting pipes transfer the dyeing solution to the drain pipe. The drain hole in the drain pipe allows for high-pressure discharge of the dyeing solution, thus preventing sedimentation and stratification in the dyeing tank. The dye solution acts as a flow mechanism, and the high-pressure discharge of the dye solution allows it to circulate within the dyeing tank, preventing sedimentation during polyester dyeing. If the dyeing device lacks the ability to prevent sedimentation, the dye solution will separate within the tank, resulting in uneven dyeing of the polyester fibers. This necessitates secondary dyeing and significantly reduces dyeing efficiency. When dyeing is required, the polyester fibers are transported separately via two sliding sleeves and guided into the dyeing tank by two guide rods.
[0013] 2. After dyeing, the polyester filaments of this utility model will be transferred to the draining tank. At this time, the polyester filaments are located on the opposite side of the two draining rollers. When the polyester filaments are conveyed out through the opening, the excess dyeing liquid on the polyester filaments is drained out by the two draining rollers. The drained dyeing liquid will fall into the draining tank and be discharged through the drain outlet for reuse periodically.
[0014] The handle and non-slip rubber sleeve make it easy to open and close the dyeing box, avoiding the inconvenience of opening and closing the box lid.
[0015] The fixing plate and fixing bolts can fix the diverter pipe, which makes the diverter pipe work better and avoids shaking during use, which would lead to unstable flow in the diverter pipe. Attached Figure Description

[0022] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.
[0023] Please see Figure 1-4 This utility model discloses a high-efficiency and energy-saving dyeing device for polyester yarn, comprising a dyeing box 1, a dyeing tank 9 on the right side of the inner cavity of the dyeing box 1, sliding sleeves 7 on both sides of the inner cavity of the dyeing tank 9, and guide rods 12 rotatably connected to both sides of the bottom of the inner cavity of the dyeing tank 9. The inner cavity of the dyeing tank 9 is equipped with an anti-sedimentation component 8, which includes a water pump 801, and the water pump 801 is fixedly connected to the front of the dyeing box 1. The input end of the water pump 801 is connected to a suction pipe 802, and one end of the suction pipe 802 is connected to the dyeing tank 9 inside the dyeing box 1. The output end of the water pump 801 is connected to the outlet pipe 803. One end of the outlet pipe 803 passes through and extends into the inner cavity of the dyeing tank 9, where a diversion pipe 805 is provided. The bottom of the diversion pipe 805 is connected to a connecting pipe 804, and the bottom of the connecting pipe 804 is connected to a drain pipe 808. A drain hole 809 is provided on the surface of the drain pipe 808. When it is necessary to prevent the dyeing solution in the dyeing tank 9 from sedimenting and stratifying, the water pump 801 is first operated, and the dyeing solution in the dyeing tank 9 is transferred to the suction pipe 802. 02. The dyeing solution is transferred to the water pump 801, which then transfers it to the outlet pipe 803. From the outlet pipe 803, the dyeing solution is transferred to the diversion pipe 805, which in turn transfers it to multiple connecting pipes 804. Finally, through the connecting pipes 804, the dyeing solution is transferred to the drain pipe 808. The drain hole 809 in the drain pipe 808 allows for high-pressure discharge of the dyeing solution, which in turn promotes flow within the dyeing tank 9. High-pressure discharge of the dyeing solution allows the dyeing solution in the dyeing tank 9 to circulate, preventing the polyester yarn from being dyed. If the dyeing device does not have the function of preventing sedimentation of the dyeing solution in the dyeing tank 9, the dyeing solution will separate in the dyeing tank 9, resulting in uneven dyeing of the polyester yarn. This would require secondary dyeing of the polyester yarn and greatly reduce the dyeing efficiency of the polyester yarn. When it is necessary to dye the polyester yarn, the polyester yarn is separated and transported through two sliding sleeves 7 and guided into the dyeing tank 9 by two guide rods 12.
[0024] A fixing plate 806 is fixedly sleeved on the surface of the diverter pipe 805, and the inner cavity of the fixing plate 806 is fixedly connected to the dyeing tank 9 by fixing bolts 807. The fixing plate 806 and fixing bolts 807 can fix the diverter pipe 805, so that the diverter pipe 805 performs better when in use and avoids shaking of the diverter pipe 805 during use, which would lead to unstable flow of the diverter pipe 805.
[0025] A drain trough 10 is provided on the left side of the inner cavity of the dyeing box 1. A through-hole 3 is provided at the top of the left side of the inner cavity of the drain trough 10. Two drain rollers 11 are rotatably connected to the top of the inner cavity of the drain trough 10. A water outlet 2 is provided at the bottom of the left side of the dyeing box 1, and the inner cavity of the water outlet 2 is connected to the inner cavity of the drain trough 10. The dyed polyester yarn will be transferred into the drain trough 10. At this time, the polyester yarn is located on the opposite side of the two drain rollers 11. When the polyester yarn is conveyed out through the through-hole 3, the excess dyeing liquid on the polyester yarn is drained out by the two drain rollers 11. The drained dyeing liquid will fall into the drain trough 10. The drained dyeing liquid is periodically discharged through the drain outlet for reuse.
[0026] The top of the dyeing box 1 is provided with a box cover 4. Both sides of the top of the box cover 4 are provided with handles 5, and the surface of the handles 5 is covered with anti-slip rubber sleeves 6. Through the handles 5 and the anti-slip rubber sleeves 6, the box cover 4 can be easily put on and taken off when the dyeing box 1 needs to be opened and closed, avoiding the inconvenience of taking on and taking off the box cover 4 when needed.
[0027] The bottom of the dyeing box 1 is provided with an anti-slip pad, and the bottom of the anti-slip pad is provided with anti-slip threads.
[0028] There are seven connecting pipes 804, and four connecting pipes 804 are equidistantly connected to the inner cavity of the diverter pipe 805.
[0029] When using this invention: to prevent sedimentation and stratification of the dyeing solution in the dyeing tank 9, the water pump 801 is first activated. The dyeing solution in the dyeing tank 9 is transferred to the suction pipe 802, then to the water pump 801, and finally to the outlet pipe 803. The outlet pipe 803 then transfers the dyeing solution to the distribution pipe 805, which in turn transfers it to multiple connecting pipes 804. Finally, the connecting pipes 804 transfer the dyeing solution to the drain pipe 808, where the drain hole 809 allows for high-pressure discharge of the dyeing solution. The function of the high-pressure discharge of the dyeing solution is to allow the dyeing solution in the dyeing tank 9 to flow. Secondly, the high-pressure discharge of the dyeing solution allows the dyeing solution in the dyeing tank 9 to roll, preventing the polyester yarn from being dyed. If the dyeing device does not have the function of preventing sedimentation of the dyeing solution in the dyeing tank 9, the dyeing solution will separate in the dyeing tank 9, resulting in uneven dyeing of the polyester yarn and requiring secondary dyeing of the polyester yarn, which will greatly reduce the dyeing efficiency of the polyester yarn. When the polyester yarn needs to be dyed, the polyester yarn is separated and transported by two sliding sleeves 7, and guided by two guide rods 12 into the dyeing tank 9 for dyeing.
