The automatic batching equipment controls the temperature in the reaction tank within a certain range during the whole system operation, and controls the temperature sensor in the jacket temperature design. The communication between the industrial control computer and the site reactor can be adjusted according to the time required for the complete reaction of the material. The reaction tank temperature and jacket temperature cascade proportioning composed of computer and electric regulating valve, the selection of control mode and control algorithm, the setting of set values and related parameters, and the display box of the real-time curve of the reaction tank temperature control, make the proportion coefficient and online debugging, the integration time and differential time can be adjusted intuitively and timely according to the shape of the real-time curve of the temperature in the reaction tank. Get full scale.
020-34563445The loader utilizes the rotational speed of the screw to measure the feeding volume, and changes the motor speed through the weight indicator, thus changing the feeding flow. Through the weighing module, the signal is transmitted to the weighing instrument, which changes the rotational speed of the motor through the frequency converter, thus changing the feeding flow. Since the load cell can transmit the change of material in the machine to the weighing instrument, the material flow always fluctuates around the set value, and the average feeding flow is highly accurate. The visualized computer operating system is designed and developed for monitoring and automated batching in the batching section. It has the features of simple and convenient operation, strong reliability, friendly man-machine interface, complete functions, etc. It can be widely used in feed, grain, pharmacy, metallurgy, chemical and other industries that need computerized automatic dosage, and has high level of intelligent informatization: the upper computer has the function of management of formula library; the intelligent report software provides a large amount of data for the production management, such as the list of dosage results, the list of raw material consumption, the list of production, the record of formula usage results, etc., which can be recorded by the time. The intelligent report software provides a large amount of data information for production management, such as the list of batching results, the list of raw material consumption, the list of production quantity, the record of formula usage results, etc. The statistics and printing function can be performed according to the time and formula, such as the production of shift report, daily report, monthly report and annual report. Meanwhile, it provides two kinds of user-defined report components, one is to adopt crystal report for secondary design; the other is to embed the data seamlessly into EXCEL report. In addition, the system can interact with other management systems to meet the requirements of deep-level data analysis. The upper part stores the parameters such as cumulative quantity, proportion, running start and stop time of each road of each run for query. The software part of the Dosage system can automatically complete the system dosage process, the computer screen real-time display of the dosage system (workflow, the software is simple to operate, the screen is realistic. Meanwhile, it has the following characteristics: the upper computer software sets the running password and important parameter password modification protection, and the user realizes the hierarchical management, which can define the personnel's authority arbitrarily.
1) Adopting Siemens S7-200 series programmable logic controller (PLC) as the core, with small volume, high precision and good stability performance.
2) Multiple scales can be controlled at the same time, with many different materials or control outputs (depending on the process).
3) Intelligent control of dosage time, no waiting between dosage scales, making the dosage cycle shorter and improving the dosage speed and output.
4) Running on Windows system platform, running faster and more stable, real-time dynamic production screen, showing the production process, intuitive operation, clear, automatic recovery function.
5) Powerful report function, can be a large number of records to store all kinds of data and tabulation printing, automatically after the completion of each production to print dosage reports, and provide the date, time, report number and the actual consumption of each type of material and other information; report extraction using a PC manual query, the end of the production of the report hosted in the computer internal, unlimited read, to ensure that the correctness and completeness of the production report.
6) Simple operation, the system has manual, semi-automatic and fully automatic three production modes.
7) PLC processing data ability, fast and stable sampling rate, the dosage process can fully meet the process requirements dosage.
8) The process can be set according to the user.
9) good reliability, the system has two kinds of control program (touch screen and industrial computer program) when one of the external kind of failure when the other one immediately cut into the operation does not affect the production, weighing and dosage system can put an end to the production failure of production out of control phenomenon.
10) Metering mixer real-time graphic display of the production process and text display of the production process, convenient for operators to operate.
11) Text file display production reports, recipe reports, etc. (there are a number of printouts by the user's choice) powerful alarm function, can minimize the scrap rate
12) When each aggregate is discharged, the frequency converter is used to control the discharging speed so that each aggregate is discharged in an equal time, which ensures the uniformity of batching.
13) Automatic monitoring software: the relationship between people and production lines from passive to active, once the production of abnormalities, the computer system immediately take the initiative to send alarms to the relevant personnel, take the initiative to do the reminder function, through the real-time online monitor, at any time to monitor the production of important information.
