[0001] This utility model belongs to the field of dyeing machine technology, and in particular relates to a low liquor ratio high temperature and high pressure dyeing machine. Background Technology

[0002] Low liquor ratio high temperature and high pressure dyeing machine is a dyeing equipment used in textile dyeing processes. It features a low ratio of dye liquor to dyed material weight and high temperature and high pressure operation. It is suitable for various blended fabrics such as cotton + spandex, nylon + spandex, polyester + spandex, as well as pure cotton knitted fabrics, plain woven fabrics, and warp-knitted fabrics. By reducing the consumption of water and other resources, it reduces the cost of textile dyeing and processing, making low liquor ratio high temperature and high pressure dyeing machine widely used in printing and dyeing enterprises.

[0003] However, existing low-liquor-ratio high-temperature and high-pressure dyeing machines operate at temperatures as high as 135°C, causing their outer shell to become extremely hot during operation, resulting in a significant waste of thermal energy.

[0004] This will also increase the working environment temperature, affecting workers' work efficiency and personal safety. There is a technical problem that it is impossible to provide heat insulation protection for the high-temperature and high-pressure dyeing machine in operation while simultaneously carrying out heat exchange treatment to improve the utilization rate of heat energy. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a low liquor ratio high temperature and high pressure dyeing machine, which can effectively solve the problems of the existing technology.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a low-liquor-ratio, high-temperature, high-pressure dyeing machine, comprising a dyeing cylinder, a base frame disposed at the bottom of the dyeing cylinder, and a guide tube disposed between the two sides of the top of the dyeing cylinder, and further comprising:

[0008] A heat insulation cover is installed on the outside of the dyeing vat.

[0009] Thermally conductive filler is disposed between the inner side of the heat insulation cover and the outer side of the dyeing cylinder, and the thermally conductive filler is evenly distributed between the inner side of the heat insulation cover and the inner side of the dyeing cylinder.

[0010] The heat exchange structure is located between the inner side of the heat insulation cover and the outer side of the dyeing cylinder.

[0011] Furthermore, the bottom end of the heat insulation cover is fixedly connected to the top end of the base frame, and the heat insulation cover has the same shape as the dyeing vat.

[0012] Furthermore, a feed inlet is inserted at the top of one side of the dyeing cylinder, a connecting pipe is inserted at the bottom of one side of the dyeing cylinder, and a drain pipe is provided at the bottom of the dyeing cylinder.

[0013] Furthermore, a first observation window is provided on one side of the front end of the dyeing cylinder, and a second observation window is provided on one side of the top end of the dyeing cylinder.

[0014] Furthermore, the heat exchange structure includes a cold water pipe, a mounting flange, a hot water pipe, a heat exchange coil, an inlet, and an outlet. The heat exchange coil is disposed between the outer side of the dyeing tank and the inner side of the heat insulation cover. The top end of the heat exchange coil has an inlet, and the bottom end has an outlet. The front end of the inlet penetrates the top of the front end of the dyeing tank and the top of the front end of the heat insulation cover. The front end of the outlet penetrates the bottom of the front end of the dyeing tank and the bottom of the front end of the heat insulation cover. A cold water pipe is disposed between the front ends of the inlets, and a hot water pipe is disposed between the front ends of the outlets. One end of each of the cold water pipe and the hot water pipe has a mounting flange.

[0015] Furthermore, the heat exchange coil is spiral-shaped and is arranged at equal intervals between the outer side of the dyeing cylinder and the inner side of the heat insulation cover. The water inlet is connected to the cold water pipe, and the water outlet is connected to the hot water pipe.

[0016] This utility model has the following beneficial effects:

[0017] This invention utilizes a heat insulation cover on the outside of the dyeing cylinder to prevent heat loss through the outer wall of the cylinder, thus avoiding significant heat energy waste and preventing the workshop temperature from rising, ensuring employee work efficiency and safety. While the heat insulation cover prevents heat loss, cold water is introduced through a cold water pipe and enters the heat exchange coil through the inlet. The heat exchange coil absorbs the heat dissipated from the cylinder and blocked by the heat insulation cover. The cold water is heated into hot water and then flows back to the hot water pipe through the outlet. Furthermore, the thermally conductive filler ensures uniform heat distribution between the heat insulation cover and the dyeing cylinder, preventing excessive temperature differences near and far from the heat exchange coil that could affect structural strength. This further ensures safe and effective utilization of the heat lost from the cylinder during dyeing machine operation, improving energy efficiency and making the equipment more environmentally friendly.

A connecting pipe 15 is inserted into the bottom of one side of the dyeing cylinder 10, and a drain pipe 7 is set at the bottom of the dyeing cylinder 10. When the dyeing machine is running, high-pressure water or steam is used to transfer heat in the fabric to be dyed, so that it reaches the temperature required for dyeing. At the same time, the dyeing agent can also be evenly dispersed in the fabric with the transfer of heat, thereby achieving the dyeing effect. After the shaping action of the guide pipe 2, the fabric moves towards the tail of the machine and begins to be evenly stacked and creeping forward at the tail of the machine to carry out the dyeing cycle. A first observation window 4 is set on one side of the front end of the dyeing cylinder 10, and a second observation window 13 is set on one side of the top end of the dyeing cylinder 10. Technicians can check the dyeing status of the textile through the first observation window 4 and the second observation window 13.

[0028] A heat insulation cover 1 is installed outside the dyeing cylinder 10. The bottom end of the heat insulation cover 1 is fixedly connected to the top end of the base frame 8. The heat insulation cover 1 has the same shape as the dyeing cylinder 10. When the dyeing machine is working, the heat insulation cover 1 isolates the heat lost from the dyeing cylinder 10, preventing the working environment temperature from rising and harming the health and safety of workers. A heat-conducting filler 11 is installed between the inner side of the heat insulation cover 1 and the outer side of the dyeing cylinder 10, and the heat-conducting filler 11 is evenly distributed between the heat insulation cover 1 and the inner side of the dyeing cylinder 10. The heat is evenly distributed between the dyeing tank 10 and the heat insulation cover 1 through the heat-conducting filler 11. A heat exchange structure is located between the inner side of the heat insulation cover 1 and the outer side of the dyeing tank 10. The heat exchange structure includes a cold water pipe 3, a mounting flange 5, a hot water pipe 6, a heat exchange coil 12, an inlet 14, and an outlet 16. The heat exchange coil 12 is located between the outer side of the dyeing tank 10 and the inner side of the heat insulation cover 1. The heat exchange coil 12 is spiral-shaped and located within the dyeing tank 10. The outer side and the inner side of the heat insulation cover 1 are arranged at equal intervals. The top of the heat exchange coil 12 is provided with a water inlet 14, and the bottom of the heat exchange coil 12 is provided with a water outlet 16. The front end of the water inlet 14 penetrates the top of the front end of the dyeing tank 10 and the top of the front end of the heat insulation cover 1. The front end of the water outlet 16 penetrates the bottom of the front end of the dyeing tank 10 and the bottom of the front end of the heat insulation cover 1. A cold water pipe 3 is provided between the front ends of the water inlet 14. The water inlet 14 is connected to the cold water pipe 3, and cold water is introduced through the cold water pipe 3 and then... The water enters the heat exchange coil 12 through the inlet 14. The medium in the heat exchange coil 12 absorbs the heat lost from the dyeing cylinder 10 and blocked by the heat insulation cover 1. A hot water pipe 6 is provided between the front ends of the outlet 16. A mounting flange 5 is provided at one end of the cold water pipe 3 and the hot water pipe 6. The outlet 16 is connected to the hot water pipe 6. After the medium in the heat exchange coil 12 absorbs heat and its temperature rises, it enters the hot water pipe 6 through the outlet 16 and is discharged for use, so as to improve energy utilization and make the dyeing machine more environmentally friendly.

[0029] When the dyeing machine is working, the heat insulation cover 1, which is set on the outside of the dyeing cylinder 10 and matches its shape, blocks the heat lost by the dyeing cylinder 10. At the same time, the heat exchange medium is introduced into the spiral heat exchange coil 12, which is set between the outside of the dyeing cylinder 10 and the inside of the heat insulation cover 14, through the cold water pipe 3 set at the top of the front end of the dyeing cylinder 10 and connected to the water inlet 14. The heat exchange coil 12 absorbs the heat blocked by the heat insulation cover 1 to heat the heat exchange medium inside it. After the heat exchange medium is heated in the heat exchange coil 12, it is discharged through the water outlet 16 set at the bottom of its front end to the hot water pipe 6 at the bottom of the front end of the dyeing cylinder 10 and connected to it for use.

[0030] Working Principle: When using the high-temperature and high-pressure dyeing machine, firstly, connect the cold water pipe 3 and hot water pipe 6 to the inlet and outlet water pipes via the mounting flange 5. Then, feed the textile to be dyed into the dyeing cylinder 10 through the feed inlet 9, and simultaneously add the dyeing agent. A connecting pipe 15 is inserted into the bottom of one side of the dyeing cylinder 10. High-pressure water or steam is used to transfer heat to the fabric being dyed, bringing it to the temperature required for dyeing. At the same time, the dyeing agent is also evenly dispersed in the fabric along with the heat transfer, thus achieving the dyeing effect. After being shaped by the guide pipe 2, the fabric moves towards the tail of the machine and... The dyeing cycle begins with evenly stacked and creeping forward at the tail end of the machine. At the same time, the heat insulation cover 1 blocks the heat lost from the dyeing cylinder 10, and the heat exchange medium is introduced into the heat exchange coil 12 through the cold water pipe 3. The heat exchange coil 12 absorbs the heat blocked by the heat insulation cover 1 and heats the heat exchange medium inside. After being heated in the heat exchange coil 12, the heat exchange medium is discharged through the water outlet 16 and then output through the hot water pipe 6 for use. Meanwhile, the technician can check the dyeing status of the textiles through the first observation window 4 and the second observation window 13. After dyeing is completed, the excess liquid is discharged through the drain pipe 7 and the textiles are taken out to complete the dyeing operation.
