Next, an example of the fabric dyeing and drying system provided by the present utility model will be described with reference to fig. 1 and 2.
As shown in fig. 1 and 2, the system includes the following components.
A cylinder 1; the top of the cylinder body 1 is provided with a nozzle assembly 11 consisting of an upper group of nozzles and a lower group of nozzles, and the inside of the cylinder body 1 is provided with a cloth collecting groove 18 for containing a fabric 19 and a cloth lifting wheel 17 which is positioned above the cloth collecting groove 18 and is used for providing power for running the fabric 19; wherein the fabric 19 passes between the two groups of nozzles in operation, and the included angle between the jet direction of the nozzles and the running direction of the fabric 19 is smaller than 90 degrees. Thus, under the pressure of the gas or liquid sprayed by the nozzles and the action of the cloth lifting wheel 17, the fabric 19 can pass through the gap between the two groups of nozzles, so that the gas or liquid sprayed by the nozzles is sprayed on the fabric 19, and dyeing, washing or drying is realized.
In the dyeing and drying process, the fabric in the cylinder 1 always presents a state as shown in fig. 2, the fabric lifting wheel 17 supplies power for the running of the fabric 19, so that the fabric 19 runs continuously and circularly, the spray head assembly 11 can spray liquid or gas-liquid mixed dye to the fabric 19, and spray the fabric 19 for a cycle in a certain time, and the dye is continuously dyed and fixed on the fabric 19 under the action of temperature.
A bottom liquid collector 8 located below the cylinder 1 and communicating with the bottom of the cylinder 1 and communicating with the nozzle assembly 11 through a pipe; wherein a master cylinder circulating pump 9 is arranged on a pipeline between the cylinder bottom liquid collector 8 and the nozzle assembly 11; the master cylinder circulation pump 9 is used for conveying the liquid in the cylinder bottom liquid collector 8 to the nozzle assembly 11 through a pipeline between the cylinder bottom liquid collector 8 and the nozzle assembly 11 so as to spray the liquid to the fabric 19 through the nozzle assembly 11. Wherein, in the dyeing process, the liquid is dye liquor, thereby realizing dyeing. In the washing, the liquid is a detergent, thereby achieving the washing.
A liquid heater 10 is provided on the conduit between the bottom liquid collector 8 and the nozzle assembly 11, the liquid heater 10 being adapted to heat the liquid passing through the conduit between the bottom liquid collector 8 and the nozzle assembly 11 to meet the temperature conditions required for dyeing or washing the fabric 19.

Because the fabric 19 is distributed in the whole cylinder body 1, the volume of the cylinder body 1 is larger, the uppermost part is connected with the nozzle assembly 11, and the lowermost part is connected with the cylinder bottom liquid collector 8, when a larger temperature difference occurs between the nozzle assembly 11 and the cylinder bottom liquid collector 8, the lower end and the upper end of the cylinder body 1 are indicated to have a larger temperature difference. The dyeing is that the fabric 19 is continuously turned in the cylinder 1 in an O-shaped mode, no matter the fabric 19 is arranged at the lower part or the upper part of the cylinder 1, the dyeing process is all existing, if a large temperature difference occurs, the dyeing difference of the fabric is easily caused when the fabric is arranged at the upper part and the lower part of the cylinder 1, and thus, the color is easily generated. The amount of liquid passing through the proportional valve 16 and the amount of liquid flowing back to the bottom liquid collector 8 by the proportional valve 16 are such that the temperatures of the liquid in the nozzle assembly 11, the liquid in the cylinder body 1 and the liquid in the bottom liquid collector 8 are similar, thereby avoiding color bloom.
Specifically, the temperature is similar through the whole process of the cylinder bottom liquid collector 8, the main cylinder circulating pump 9, the cylinder body 1, the liquid heater 10, the nozzle assembly 11 and the cylinder bottom liquid collector 8, and the process is a circulation process, so that the temperature of the whole process is similar, when the temperature deviates, the temperature can be regulated through the proportional valve 16, and the proportional distribution of the proportional valve 16 is the adjusted proportion of the liquid heater 10 to the nozzle assembly 11 and the liquid heater 10 to the cylinder bottom liquid collector 8. The amount of liquid from the liquid heater 10 to the nozzle assembly 11 may be increased when the temperature in the nozzle assembly 11 is lower, and the amount of liquid from the liquid heater 10 to the bottom liquid collection 8 may be increased when the temperature in the bottom liquid collection 8 is lower. The temperature sensor can be artificial or automatic, and the automation is realized by adding a temperature probe at each part, monitoring the temperature in real time and automatically adjusting when the temperature does not accord with the setting.
