Mixing Plant PLC System

The mixing plant PLC system of the commercial concrete station for commercial concrete is managed by an upper computer, and controlled and monitored by a lower computer PLC, achieving automation and intelligence throughout the entire process from batching measurement, and mixing, to discharge production. To improve ingredient accuracy, enhance product quality and yield, and reduce costs.

Features of Mixing Plant PLC System

  1. A work control computer can control multiple batching scales and silos with a multifunctional weighing manager.
  2. PLC controls equipment action, and frequency converter controls ingredient accuracy with high precision.
  3. Adopting 232 bus, simplifying instrument and computer wiring, ensuring reliable equipment.
  4. Multiple batching scales are composed of scales with different ranges and structures, which are suitable for batching raw materials such as powders and liquids.
  5. All operational data such as production process parameters, formula input, production statistics, historical data queries, and process control are controlled by computers and can connect to the local area network.

System features

  1. Automatic control of the start and stop of the batching screw conveyor for batching.
  2. Start and stop the valve of the batching scale feeder.
  3. Start and stop of the mixer, control of mixing time, and discharge control of the mixer.
  4. Input and modification of formulas.
  5. Various process parameter equipment related to ingredient mixing.
  6. Quantitative packaging of computer-controlled products.

Function of Mixing Plant PLC System

The automation level of the ingredient control system is high:

  1. Mixing plant PLC system can automatically complete the system ingredient process flow, and the computer screen displays the ingredient system workflow in real time. The software operation is simple, and the screen is realistic.
  2. The control methods of the mixing plant PLC system are diverse, and the system is equipped with multiple operation modes such as upper-level manual/automatic, PLC automatic, control room manual, and on-site manual, which can be operated and controlled in multiple locations as needed.
  3. According to the process flow and equipment layout, the start-up sequence and delay time of each batching scale can be selected.
  4. Manual feeding on-site prompt and feeding response function.
  5. Manual ingredients can also enter the statistical database.
  6. The upper computer software is equipped with password protection for running and important parameter password modification, and users can achieve hierarchical management and freely define personnel permissions.
  7. The mixing plant PLC system can be equipped with an industrial television monitoring device to observe the operation of equipment such as ingredients and mixers.
  8. Powerful interlocking functions are installed between upper and lower-level equipment to ensure safety during production, operation, and maintenance processes.
  9. The instrument has functions such as parameter backup, online replacement, and manual testing.
  10. It is convenient to define alarm categories such as out-of-limit alarm, out-of-tolerance alarm, limit alarm, etc. The alarm output can be selected from one or more of the screen flashing, dialog box prompt, saved alarm event, printed alarm event, played or looped alarm prompt sounds.
  11. All input and output points can be tested, making it convenient for customers to quickly find fault points.

The information technology level of the ingredient control system is high:

  1. The upper computer has a recipe library management function;
  2. The upper-level stores the cumulative quantity, ratio, and start and end time of each run for easy querying;
  3. Intelligent reporting software provides a large amount of data information for production management, such as ingredient result lists, raw material consumption lists, production quantity lists, formula usage result records, etc. It can provide statistical and printing functions for production shift reports, daily reports, monthly reports, and annual reports based on time and formula.

1.5Additive feed controlAdditive measurement and control method: using peristaltic pump+PLC external start control.Set1CustomizedAdditive measurement and control method: using peristaltic pump+PLC external start control. The PLC system outputs an external start control signal (relay passive contact pulse signal) to start the peristaltic pump. The peristaltic pump adopts a timed control method to feed the admixture to the mixer, and the peristaltic pump automatically stops when the feeding time is up. The required dose is manually indicated and operated by the external peristaltic pump equipment itself
1.6Mixer controlCylinder door dischargeSet1CustomizedPLC control reference logic:1) The mixer has no material, allowing the scale to unload the material; After the scale is unloaded to the mixer, it is placed in a concrete state;2) After the unloading of the 2 scales is completed, and the water and additives are added, start stirring at a fixed time. When the stirring time is up, let it mix well;3) After mixing, it is allowed to unload the concrete;4) Mixer discharge: automatic/manual selection
