Quantity Ratio Automatic Feeding System

The Quantity Ratio automatic feeding system adds the ingredients in the set proportion and makes feedback adjustments based on the weight of the liquid and gas. The amount of ingredients and the lag time can be set. When the drop value changes, the extent of the change and the extent of ingredient adjustment can also be set. When the weight after filtration changes, the batching system should be adjusted immediately. In the control system, a dialog window is set up, allowing the operator to select the relevant quantities to be monitored and set (such as drop quantity, weight after filtration, etc.). The feeding machine alarms and controls the liquid and gas detection. When the liquid and gas detection low alarm is triggered, an alarm will be triggered and the exhaust fan will be turned on. When the liquid and gas detection reaches a high alarm, an alarm will be triggered, the exhaust fan will be turned off, and the neutralization device will be automatically activated. The high and low alarm values for liquid and gas detection can be set.

The Quantity Ratio main function of the automatic feeding system is to add flocculant to the liquid through the feeding equipment, so as to absorb the small particles in the incoming liquid and achieve the effect of flocculation. The feeding system is mainly composed of weighing conveyor, silo and material level switch, switch valve, feeding pump, Feeder, weighing module, Weighing system, etc. The addition of the feed agent adopts dry metering and wet dosing. The supply amount should be proportionally added according to the weight of the incoming liquid, and then feedback adjusted according to the quantitative value of the weighing instrument. The proportion coefficient and set value of the dosing are adjustable. The control system should ensure the accuracy of measurement, with the error between the actual dosage and the calculated dosage in the system being less than 0.5%. The regulation of the feeding agent dosage should achieve a good combination of sensitivity and stability to avoid frequent adjustments in the feeding system and fluctuations in liquid quality due to adjustment lag.

The automatic feeding system adds the ingredients in the set proportion and makes feedback adjustments based on the weight of the liquid and gas. The amount of ingredients and the lag time can be set. When the drop value changes, the extent of the change and the extent of ingredient adjustment can also be set. When the weight after filtration changes, the Batching system should be adjusted immediately. In the control system, a dialog window is set up, allowing the operator to select the relevant quantities to be monitored and set (such as drop quantity, weight after filtration, etc.). The Feeding machine alarms and controls the liquid and gas detection. When the liquid and gas detection low alarm is triggered, an alarm will be triggered and the exhaust fan will be turned on. When the liquid and gas detection reaches a high alarm, an alarm will be triggered, the exhaust fan will be turned off, and the neutralization device will be automatically activated. The high and low alarm values for liquid and gas detection can be set.


Application of liquid pumping and mixing batching system
The batching system adopts dual CPU to form a redundant system, and the STEP7MicroWin V4.0SP6 programming software provided by Siemens is used as the man-machine interface to write debugging programs and download programs. The PC and PLC experimental machine are connected by a PC/PPI cable for communication, and the corresponding parameters are set.
Application of weighing modules in large storage tanks
Weighing modules can be used as storage and irrigation materials in and out of the warehouse measurement, can also be used for process flow control, in general, according to the shape of the tank and the installation of different ways to choose 3 or 4 weighing modules to complete, especially suitable for chemical plant production process quantitative feeding system occasions to use.
Reactor feeding and dosage system realization
Reaction kettle feeding dosage system through the explosion-proof electronic weighbridge direct collection of weight signals, automatic control of weighing, the operator through the keyboard or the mouse in the upper computer human-machine interface (HMI) on the input charging information (charging type, weight, etc.), monitoring the whole process of charging control, printing the results of the charging and production reports, to achieve the process of charging the measurement and control of the integration of the management, is not lost as a practicable and effective method.
