Technical Field

[0001] The utility model relates to the technical field of alkali solution mixing equipment, in particular to an alkali concentration automatic configuration device. Background Art

[0002] Dyeing and finishing equipment such as alkali shrinking machines and mercerizing machines usually have a working tank immersed in alkali solution, and the fabric is treated by being immersed in the alkali solution in the working tank. The existing method for controlling the concentration of alkali solution in the working tank usually adopts manual titration, and the operator manually adjusts the size of the valve to add original alkali, diluted alkali or water to control the concentration of alkali solution in the working tank.

[0003] However, manual titration has the following disadvantages in work: different operators often have different titration results, which is very easy to produce errors; there is a huge time interval between detection and adjustment of alkali solution concentration, and during this interval, the concentration of the alkali solution has changed again, so the adjusted value is not adjusted according to the concentration at the adjustment time, and there is a large error; manual methods cannot achieve continuous detection and cannot continuously adjust the alkali solution concentration, making it difficult to keep the alkali solution at the set concentration value, affecting the reproducibility of subsequent dyeing processes, resulting in a high rate of defective fabrics, and failing to achieve automated control, increasing the number of workers and labor costs, resulting in waste of resources such as water, steam, and chemicals, increasing sewage treatment costs, and affecting the environment, which urgently needs improvement.
