During the dyeing process with reactive dyes, a large amount of mirabilite (or table salt) and soda ash are used, and the labor intensity of manual feeding is extremely high, which affects the production efficiency. Meanwhile, manual feeding will result in errors and waste, which in turn affects the product quality. The Tianfu automated liquid dispensing systems(salt and alkali) is specifically designed for the automatic dispensing of such high-volume powder additives. After its application, it can save labor, reduce labor intensity, enhance production efficiency, and boost the first-time pass rate of products.
For low bath ratio dyeing in dyeing vats, Tianfu has developed a product that directly conveys salt-alkali powder into the dyeing vats.
Advantages and Characteristics:
1. Saturated solution dispensing method: When a dispensing order is received, there is no need to dissolve the material; it can be dispensing immediately, achieving high dispensing efficiency.
2. The large storage tank is equipped with a stirrer and a constant temperature device to keep the concentration of the salt-alkali solution uniform in the tank.
3.For salt and alkali packaged in ton bags, the unit cost of raw materials in large packages is cheaper than that in small packages, thus reducing costs.
4. Dual-pump configuration with one in operation and one as a standby, reducing downtime.
5. It supports simultaneous measurement and dispensing for multiple branches, ensuring high dispensing efficiency.
6.The main circulation mode can be optionally equipped with large and low_flow dispensing modes, which can enhance the dispensing accuracy.
7. A detailed emptying design to prevent crystallization when the pipeline stops flowing.
8. Comprehensive monitoring of all aspects including material dissolving, material storing, and dispensing, with automatic alarms in case of abnormal states.
9.The consumption situation is automatically counted and a report is generated.
