The automation level of powder raw material storage and feeding is related to the production, performance and quality control of products. Improving the level of power supply automation will make a significant contribution to the production efficiency of relevant fields. The automatic storage and processing system of powder ingredients designed and manufactured by Siehe has solved the defects of traditional pressure difference, unstable quality and poor statistical management. At the same time, it has realized database management and network management, which can be connected to the network management of the factory, and can transmit the production data to the network management of the factory in real time, thus realizing the functions of backup, query, management, etc, Statistics and data printing have greatly improved the management level of the factory. On the other hand, optimizing the process and improving the control precision and control mode in the production process are the most effective means to improve the performance and quality of products, and also the most direct method to reduce production costs and enhance the competitiveness of key products of enterprises.
Control Mode | Measuring way | Application Industry |
Monitoring of PC + PLC in real time (DCS Main Line from same place) | Weight method (weight increase method, weight loss method) | It is applicable to paint, ink, daily chemicals, adhesives, dyes, oil, lubricants, pharmaceuticals, food, paper, pesticides, building materials and other industries. |
The Powder Storage and Automatic Batching System is mainly composed of conveying equipment, weighing body, high-precision weighing sensor, weighing demonstration controller, industrial control machine, frequency converter, control cabinet, process simulation screen, etc.
The processing methods of ingredients can generally be divided into weight increase method and weight reduction method.
Weight increase method: the raw material hopper is equipped with a level gauge (high level feeding stop, low level feeding INCIO), with one or more weight hoppers (depending on the quantity and pressure of the material). The feeder is started quickly according to the batching process. When the weight is close to the approximate value (the specific value depends on the adjustment), Used for rapid feed device. Start the precision feed device until the weight is close to the required value, and considering the floating material, the precision feed device will gradually reduce the speed and advance (the predicted value depends on the adjustment). At the same time, the check valve is closed immediately to avoid additional load. The instrument can calculate the power supply at any time. When the precision feed device stops, it will delay Δ t minutes. After it is fixed, the value will be displayed on the instrument, that is, the quantity of the first material. Therefore, the second material will soon be sent to the batching warehouse. Repeat the above process until the feeding process of all raw materials is completed.
