Single Silo Single Weigh Type
The single silo single weigh dynamic automatic batching system is an automatic batching device that can be used with BB fertilizer equipment, organic fertilizer equipment, compound fertilizer equipment, and blended fertilizer equipment. This equipment adopts an independent configuration of "one bin, one scale," with each raw material bin corresponding to its own high-precision weighing module, avoiding interference from mixed raw materials at the source. The system's dynamic weighing algorithm can capture the weight changes of materials in real time during their descent, and combined with frequency conversion feeding technology, it achieves stepped feeding through "fast, medium, and slow" feeding. Actual testing shows that the system can control the batching accuracy of fertilizer raw materials in different forms, such as granular and powdered materials, within ±0.2%, far exceeding the industry average of ±1%.
The value of the single-bin, single-weighing dynamic automatic batching system in fertilizer production is reflected in multiple dimensions, including ensuring batching accuracy, improving the level of production automation, and ensuring stable control of product quality. The system achieves seamless integration of production processes through fully automated control. From monitoring material levels in the raw material silo and automatic replenishment to dynamic weighing, batching, and finished product conveying, the entire process requires no manual intervention and can operate continuously 24 hours a day. Compared with traditional semi-automated batching lines, this system can increase the batching volume per unit time by more than 30%.
Equipment Structure
The single silo single weigh dynamic automatic batching system mainly consists of a storage system (each raw material bin, material level sensor), a feeding system (electromagnetic vibratory feeder, screw feeder, etc.), a weighing system (weighing sensor, junction box, weighing hopper, weighing instrument), a control system (PLC controller, host computer, human-machine interface), and a discharge and conveying system (discharge valve, belt conveyor).
Application range of equipment
The single-material warehouse weighing dynamic automatic batching system is widely used in the batching stage of fertilizer production lines for BB fertilizer, organic fertilizer, compound fertilizer, and blended fertilizer. It can adapt to the fertilization needs of different crops and soil types, and the system can store hundreds of formula parameters, enabling rapid recall and modification of formulas.
Types of available raw materials
The single-material warehouse weighing dynamic automatic batching system can handle a wide variety of raw materials. Organic raw materials include livestock and poultry manure, crop straw, humic acid, etc. Fertilizer raw materials include urea, potassium chloride, potassium sulfate, monoammonium phosphate, diammonium phosphate, etc. Additives include trace elements, biological agents, etc. The system's control parameters can be adjusted according to the characteristics of the raw materials, achieving stable batching whether it is high-moisture fermentation materials or light peat moss.
Working principle of the equipment
The working principle of the single-bin single-weighing dynamic automatic batching system is based on the coordinated operation of sensors, PLC controllers, and actuators. The system controls the feeding device to add material to the weighing hopper according to the set formula, and the weighing sensor monitors the weight change in real time. When the set value is reached, feeding stops and the material is discharged.
Equipment operation method
(I) Pre-start Inspection: Check that each hopper has sufficient raw materials. Check that the weighing sensors and junction boxes are functioning properly. Check that the feeding device is operating normally.
(II) Formula Setting and Startup: Retrieve or input the formula through the human-machine interface. Set the target weight and error range for each raw material. Start the automatic batching program.
(III) Operation Monitoring: Monitor the weighing data displayed on the instrument or host computer in real time. Observe the operating status of each piece of equipment. When an abnormality occurs, the system will immediately sound an audible and visual alarm and locate the fault point.
(IV) Shutdown Operation: After completing the batching task, shut down each piece of equipment in sequence.
Equipment maintenance methods
(I) Daily Maintenance: Inspect the equipment's operation daily. Observe whether the scale body is deformed or corroded.
(II) Periodic Maintenance: Clean, lubricate, and calibrate the equipment regularly. Regularly inspect the infeed/discharge mechanisms, valves, flexible connections, and other components.
(III) Calibration Management: The system should be calibrated regularly.
Equipment troubleshooting
Inaccurate weighing: Check if the sensor is under even force. Replace damaged or damp sensors. Check if water has entered the junction box. Recalibrate the scale after troubleshooting.
Instrument display values fluctuate: Check if water has entered the junction box or if the circuit board is damp.
No material feeding or poor feeding: Check if there is raw material in the hopper. Check if the raw material is clumped. Check if the solenoid valve or motor is damaged. Check for poor contact in the circuit.
Material blockage: Adjust the feeding speed. Optimize the hopper cone angle design. Use a feeder with a stirring function.
Application of equipment in production line
The single-material warehouse weighing dynamic automatic batching system is located between raw material storage and mixing in the fertilizer production line, undertaking the core task of precise batching. The system achieves seamless connection of production links through full-process automated control.
