[0025] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0026] A concentration device for pigment extraction, comprising a concentration box 1, a shell 2 is fixedly installed on the outer side of the top of the concentration box 1, a steam inlet 3 is connected to the left side of the top of the shell 2, a steam outlet 4 is connected to the right side of the bottom of the shell 2, and a feeding pipe 20 is fixedly installed on the left side of the top of the concentration box 1; a concentration chamber 5 is opened inside the top of the concentration box 1, a return pipe 6 is connected to the right side of the concentration chamber 5, a machine box 7 is fixedly installed on the outside of the right bottom of the concentration box 1, and a water pump 8 is fixedly installed inside the machine box 7; a cold water chamber 9 is opened inside the bottom of the concentration box 1, one end of the return pipe 6 away from the concentration chamber 5 passes through the shell 2 and is connected to the water pump 8, and the other end of the water pump 8 is connected to the bottom of the cold water chamber 9;

[0027] In this embodiment, after the high-temperature steam heats the pigment solvent, the water in the solvent evaporates into water vapor. When the high-temperature steam circulates in the cold water chamber 9, since the middle part of the cold water chamber 9 is located inside the shell 2, the gas in the high-temperature steam can be recovered through the shell 2 for waste heat, thereby achieving the purpose of energy saving.

[0028] like Figure 4 As shown, the concentration tank 1 is provided with an inner cavity 10 between the concentration chamber 5 and the cold water chamber 9, a discharge port 11 is fixedly installed in the middle of the bottom end of the concentration chamber 5, the bottom end of the discharge port 11 is connected to a feed pipe 13 through an electric valve 12, and the bottom end of the feed pipe 13 passes through the cold water chamber 9 and is fixedly provided with a feed port 14 at one end outside the concentration tank 1;

[0029] In this embodiment, after the water pump 8 is started, the high-temperature water vapor is sent into the cold water chamber 9 through the reflux pipe 6 for cooling. After the high-temperature steam enters the cold water chamber 9, the residual pigment in the gas will dissolve in the water inside the cold water chamber 9, and the gas will be discharged from the exhaust pipe 21 after cooling, so that part of the pigment in the water vapor can be recovered to avoid waste.

[0030] like Figure 2 As shown, a motor 15 is fixedly installed at the middle of the top of the concentration box 1, and an output shaft of the motor 15 is located inside the concentration chamber 5 and a stirrer 16 is fixedly installed at one end thereof;

[0031] In this embodiment, after the motor 15 is started, it drives the stirrer 16 inside the concentration chamber 5 to continuously stir the pigment solvent, which can increase the contact area between the pigment solvent and the air, thereby improving the evaporation efficiency.

[0032] like Figure 2 As shown, the concentration tank 1 is located on the left side of the cold water chamber 9 and is connected to a water supply port 17, and the lower side of the concentration tank 1 near the water supply port 17 is connected to a drain port 18;

[0033] In this embodiment, after the water in the cold water chamber 9 dissolves part of the pigment, the water can be extracted and then concentrated again.

[0034] like Figure 3 As shown, a plurality of heat conducting plates 19 are provided on both sides of the inner wall of the housing 2, and the heat conducting plates 19 are made of ceramic material;

[0035] In this embodiment, the heat conducting plate 19 disposed inside the shell 2 is convenient for increasing the contact area with the steam, and can also guide the steam, thereby extending the circulation time of the steam inside the shell 2, thereby improving the heat exchange rate.

[0036] like Figure 2 As shown, the top of the cold water chamber 9 near the feeding port 14 is connected to the outside with an exhaust pipe 21, and the height of the exhaust pipe 21 is greater than the height of the water supply port 17;

[0037] In this embodiment, the height of the exhaust pipe 21 is greater than the height of the water supply port 17 , so that the gas can be smoothly discharged from the device through the exhaust pipe 21 after being cooled by the water inside the cold water chamber 9 .

[0038] Working principle: During operation, the pigment solvent is poured into the concentration chamber 5 from the feeding pipe 20, and then the motor 15 is started. After the motor 15 is started, the agitator 16 inside the concentration chamber 5 is driven to continuously stir the pigment solvent. At the same time, high-temperature steam is input from the position of the steam inlet 3. The high-temperature steam will heat the pigment solvent inside the concentration chamber 5, and then be discharged from the steam outlet 4. After the high-temperature steam heats the pigment solvent, the water in the solvent evaporates into water vapor. At this time, the water pump 8 is started. After the water pump 8 is started, the high-temperature water vapor is sent into the cold water chamber 9 through the reflux pipe 6 for cooling. After the high-temperature steam enters the cold water chamber 9, the residual pigment in the gas will dissolve in the water inside the cold water chamber 9, and the gas will be discharged from the exhaust pipe 21 after cooling. When the high-temperature steam circulates in the cold water chamber 9, since the middle part of the cold water chamber 9 is located inside the shell 2, the gas in the high-temperature steam can be recovered through the shell 2 for waste heat.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
