[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figures 1 to 4 The improved TEG dyeing vat shown in the figure comprises a vat body 1, a plurality of cloth lifting cylinders 2 are installed on the top of the vat body 1, a cloth conveying air duct 3 is connected to the back of the cloth lifting cylinder 2, and the cloth conveying air duct 3 is connected to the vat body 1 at one end away from the cloth lifting cylinder 2, a liquid infusion pipeline 4 is arranged in the inner cavity of the vat body 1, an overflow pipe 5 is connected to the outer side of the liquid infusion pipeline 4 in turn through a connecting pipe, a barrel 6 is connected to the end of the liquid infusion pipeline 4 away from the vat body 1, a main conveying pump 7 and an exchanger 8 are arranged in turn on the liquid infusion pipeline 4, and the bottom of the vat body 1 is connected to the bottom of the vat body 1. There is a collecting frame 9, the bottom of the collecting frame 9 is connected to a storage tank 10, the inner cavity of the storage tank 10 is provided with a dye mixing assembly 11, a collecting cup 12 is fixed to the outside of the overflow pipe 5, the bottom of the collecting cup 12 is connected to a collecting pipe 13, the end of the collecting pipe 13 away from the collecting cup 12 passes through the cylinder 1 and extends to the inner cavity of the collecting frame 9, the bottom of the storage tank 10 is connected to a reflux pipe 14, the end of the reflux pipe 14 away from the storage tank 10 is connected to the exchanger 8, and a reflux pump 15 is installed on the reflux pipe 14;

[0021] The used dye in the cylinder body 1 is collected through the collecting pipe 13 and the guide pipe 19 and introduced into the collecting frame 9. Then, the concentration of the dye in the storage tank 10 and the barrel 6 is detected by the sensor 16 for measuring the dye concentration. The concentrated dye is quantitatively introduced into the storage tank 10 through the supply pipe 114 by the metering pump 115. Then, the dye concentration in the storage tank 10 and the dye concentration in the barrel 6 are basically balanced through stirring. The dye is directly transported by the reflux pump 15 into the exchanger 8, which not only realizes recycling but also reduces the use cost of the dye cylinder.

[0022] The dye mixing component 11 includes a stirring motor 111 fixed to the bottom of the storage tank 10. The output shaft of the stirring motor 111 passes through the inner cavity of the storage tank 10 and is fixed with a stirring shaft 112. A stirring impeller 113 is fixed to the outside of the stirring shaft 112. The side wall of the storage tank 10 is connected to a supply pipe 114 of concentrated dye solution. A metering pump 115 is installed on the supply pipe 114. The stirring motor 111 drives the stirring shaft 112 to rotate, and then the stirring shaft 112 drives the stirring impeller 113 to rotate, so as to stir the dye to ensure that dyes of different concentrations are mixed evenly. At the same time, the metering pump 115 can quantitatively deliver high-concentration dyes to the storage tank 10 to avoid increasing the concentration of the original dye.

[0023] The inner cavities of the barrel 6 and the storage tank 10 are both equipped with sensors 16 for measuring the dye concentration. The sensors 16 are distributed at different heights of the barrel 6 and the storage tank 10. Through the setting of the sensors 16, real-time detection of the dye concentrations in the storage tank 10 and the barrel 6 is convenient, ensuring that the dye concentration in the storage tank 10 is basically consistent with the dye concentration in the barrel 6.

[0024] The outside of the reflux pipe 14 is connected to a drain pipe 17, and control valves 18 are installed on the drain pipe 17 and the reflux pipe 14. Through the setting of the drain pipe 17 and the control valve 18, it is not only convenient to return the liquid transported by the reflux pump 15 to the exchanger 8, but also to discharge the waste liquid from the dye vat system, thereby realizing the switching of different functions.

[0025] The bottom of the cylinder body 1 is connected with a guide pipe 19, which extends upward and is connected with the cloth conveying air duct 3. The setting of the guide pipe 19 facilitates the recovery of the dye carried by the cloth in the cloth conveying air duct 3.

[0026] The collecting cup 12 is horn-shaped, and the bottom of the collecting frame 9 is concave toward the middle. The shape of the collecting cup 12 and the collecting frame 9 is limited to facilitate faster diversion of the dye when collecting the dye to avoid dye retention.

[0027] When in use, the dye is poured into the barrel 6, and the main delivery pump 7 pours the dye into the exchanger 8 for heating. The heated dye flows into the overflow pipe 5 in the cylinder 1 through the infusion pipe 4. The dye forms an overflow column of about 60 cm at the outlet of the overflow pipe 5, which is convenient for dyeing the cloth. Then the cloth lifting roller in the cloth lifting cylinder 2 lifts the cloth into the cloth conveying air duct 3. After the overflow column dyes the cloth, the concentration gradually decreases. At this time, the used dye is introduced into the collection cup 12 and the collection pipe 13 below the cylinder 1. The dye is collected in the collecting frame 9 and finally flows into the storage tank 10. The sensor 16 detects and compares the concentrations of the dye in the storage tank 10 and the barrel 6. The controller controls the metering pump 115 to pass the high-concentration dye into the storage tank 10 through the supply pipe 114. Under the drive of the stirring motor 111, the stirring impeller 113 mixes and stirs the dyes of different concentrations to make the dye concentration in the storage tank 10 consistent with the dye concentration in the barrel 6. Finally, the reflux pump 15 re-transports the prepared dye into the exchanger 8 for recycling.

[0028] TEG dye vats are named after the special dyeing process, which is the air overflow dyeing process;

[0029] The air overflow dyeing process is a dyeing technology that combines the characteristics of air flow dyeing and overflow dyeing. The following is its related introduction:

[0030] Dyeing principle

[0031] Airflow dyeing principle: Use strong airflow to blow open the fabric and drive it to move, so that the fabric constantly changes its rope state during the dyeing process, achieving "no memory wrinkle" dyeing. The dye liquid is sprayed evenly onto the fabric after being atomized. Under the action of the airflow, the dye liquid quickly penetrates into the fabric to complete the dyeing.

[0032] Overflow dyeing principle: After the dye liquid is fully and evenly mixed in the barrel, it is heated and flows into the dye vat through the overflow pipe to form a dye overflow, so that the grey cloth is fully soaked and dyed. The fabric is pushed by the overflow and assisted by the cloth lifting roller in the dye liquid, and circulates repeatedly in the dye vat to achieve the dyeing effect.

[0033] Process

[0034] Pretreatment: After water and cloth are fed in, corresponding auxiliaries such as desizing agent and scouring agent are added, and the temperature is raised to a certain temperature for heat preservation treatment to remove impurities and slurry on the fabric, and then drainage is carried out.

[0035] Dyeing: After water enters, electrolytes such as salt are added first, and then auxiliaries such as dyes and alkalis are added. The fabric is fully contacted with the dye solution through the combined action of airflow and overflow to complete the dyeing process, and finally the water is discharged.

[0036] Post-treatment: Wash with water to remove floating color and residual auxiliaries on the surface of the fabric, then carry out acid washing, soap washing and other treatments as needed to further improve the color fastness and quality of the fabric, and finally wash it several times until the fabric meets the requirements.

[0037] Equipment Features

[0038] Cloth lifting wheel and atomization chamber: The cloth lifting wheel lifts the fabric and sends it into the atomization chamber. The dye liquid in the atomization chamber is quickly atomized into tiny particles under the wind pressure generated by the fan, which fully contacts the fabric and improves the dyeing effect.

[0039] Duct design: The horizontal tube of the duct adopts a conical design to ensure uniform wind pressure, so that the atomized dye can be evenly sprayed on the fabric, improving the dyeing quality, while reducing the air supply requirements of the fan, saving energy and reducing noise.

[0040] Automatic control system: The advanced PLC control system can realize fully automatic control of the dyeing process. Operation and parameter setting are carried out through the touch screen. The operation is simple, which reduces the influence of human factors on dyeing quality and improves production efficiency and product quality stability.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
