Feeding system is suitable for the site without continuous dosage requirements, can be batch dosage, batch allows the existence of a certain time interval, kettle weighing before and after the feeding of the two batch time interval of 3 ~ 5min, each batch of material from a variety of materials, materials accounted for the ratio of the requirements of the process over a period of time in a relatively fixed proportion of the composition of a single material requirements are not stringent, as long as the proportion of the composition of the material in the more batches to meet the process requirements. Requirements can be. Automatic feeding system due to material measurement, transportation, adding and other aspects of the time can be overlapped, in the control process can be used in parallel, in order to save feeding time, improve feeding speed. Various materials are stored in different silos, silo feeding is generally used in the form of electric vibration feeding, screw feeding or gate feeding. Measuring silo and equipped with pressure or weighing module for force and power conversion, the signal is amplified by the secondary instrumentation processing access to PLC or DCS to complete the measurement. In some applications with wide time requirements, a measuring trolley can be used for uniform measurement, measuring trolley running along the track, positioned in turn to the bin under the proportional material dosage, the dosage of various materials using the subtraction method of calculation. There is also a single fixed measuring bin way, the bins in a ring-like distribution around a measuring bin, the measurement of the material also uses the subtraction method, the material from the chute or conveyor in order to proportionally add to the measuring bin. The materials after dosing and metering are assembled, generally forming a layer or segment distribution, and then conveyed to the receiving port by the conveying equipment (such as screws or trolleys) to enter the next process, i.e., completing a batch of material dosing.
020-34563445The Weighing system adopts a touch screen as the human-machine interface and is composed of weighing instruments, temperature control instruments, water addition control devices and starch conveying control devices, etc. The system is also equipped with some pumps, shut-off valves, liquid level and material level sensors. Monitor the deviation during the feeding process through the screen and automatically correct the subsequent feeding ratio according to the formula ratio to ensure the accuracy of the formula. It can achieve data communication with the user's production management system. Through parameter setting, the control quantity can be automatically determined based on the order to be produced. The program can then automatically modify the formula to meet the process requirements of the batching production line.
The feeding system is suitable for sites without continuous batching requirements. Batching can be carried out by batch, with a certain time interval allowed between batches. The time interval between two batches before and after the weighing and feeding of the reaction vessel is 3 to 5 minutes. Each batch of materials is composed of multiple materials, and the proportion of materials is relatively fixed within a certain period of time according to the process requirements. The composition ratio of individual materials is not strictly required. As long as the material composition ratio in many batches can meet the process requirements, it is fine.
The automatic feeding system, due to the fact that the material measurement, conveying, and addition processes can overlap in time, can adopt a parallel control method in the control flow to save feeding time and increase feeding speed. All kinds of materials are stored in different silos respectively. The feeding of silos generally adopts forms such as electric vibration feeding, screw feeding or portal feeding. The metering chamber is equipped with a pressure or weighing module for force-to-electricity conversion. The signal is amplified and processed by the secondary instrument and then connected to the PLC or DCS, etc. to complete the measurement. In some application scenarios with strict time requirements, a metering trolley can be used for unified measurement. The metering trolley runs along the track and is positioned under each silo in sequence to add materials in proportion. The addition amounts of various materials are calculated by the subtraction method. There are also cases where a single fixed metering silo method is adopted. Each silo is distributed in a ring around one metering silo, and the measurement of each material is also carried out by the subtraction method. The materials are successively added to the metering silo in proportion through the chute or conveyor. After the materials have been proportioned and measured, they are generally distributed in layers or sections after being collected. They are then conveyed to the receiving port by conveying equipment (such as screws or trolleys) and enter the next process, thus completing the addition of a batch of materials.
