Multi-bin weighing system adopts PLC ladder diagram programming to realize various logic sequence control and flow rate detection control. The control system can realize automatic/manual switching and frequency conversion/industrial frequency switching (if it is necessary to inject the reaction tank quickly, the industrial frequency operation mode can be used). When using the frequency conversion start-up mode, the frequency converter frequency rises to 25Hz in the first 3s, and then drops to the lowest frequency after 2s. This start-up process allows the air in the transfer pipe to be exhausted, and the starting flow rate is extremely small. Then the frequency converter is slowly accelerated from the lowest frequency to ensure that the flow rate is increased linearly, so that the injection volume increases with time in square proportion to meet the process requirements.

The feeding system can realize measuring and proportioning conveying for many kinds of materials, featuring accurate measuring, fast speed, no abrasion to materials and high measuring precision. It is characterized by high degree of automation, simple operation, environmental protection, accurate feeding and high proportioning accuracy. Through the computer control center, the whole production process can be viewed, and the operation process can be effectively controlled, which eliminates the errors that may be caused by human operation. It is widely used in pharmaceutical, food and chemical industries.
Feeder through the tank through the weighing module measurement to add liquid (or powder) and timed mixing, mixing is completed to open the material gate, the mixed material into the transition bin. The material in the transition bin and the resin weighed at the same time evenly into the matching material hopper lifter will be sent to the material bin. Completion of the process site temperature, pressure, flow, such as real-time monitoring, recording of historical data, complete the record of production parameters, hand / automatic state, dosage state, protection state system in the form of sound and light alarm form of early warning, to ensure that the system in the fully automatic control mode of stable operation.
Main features of the feeding system
1) Flexible layout and easy installation;
2) The material is transmitted in the closed pipe, no dust leakage, high environmental quality;
3) The Weighing system can realize many kinds of processes at the same time during the conveying process, such as: mixing, batching, grading, packing, dust removing and so on;
4) Avoid moisture, non-destructive and mixing of other sundries of the conveyed materials, avoid manual intervention and ensure product quality;
5) For flammable and explosive materials, inert gas can be used for closed-loop transportation to improve system safety;
6) Reduce packaging and handling costs;
7) The weighing system can realize intermittent or continuous conveying, multi-point feeding and multi-point unloading, flexible program, wide range of options;
8) Less moving parts, easy maintenance, high reliability;
9) High degree of automation, suitable for continuous production process.
