1. Introduction to RX-GMJ intelligent dosing system
The RX-GMJ intelligent dosing system consists of a control host, a diaphragm metering pump, a medicine tank and related medicine pipelines. The dosing amount at each point is set through the control host, and the control host controls each dosing metering pump. , thereby realizing and completing the process control requirements for the dosage of each dosing point.
The RX-GMJ intelligent dosing system uses a diaphragm metering pump as the execution equipment unit for dosing. As an ideal equipment for precise fluid measurement and dosing, the diaphragm metering pump uses a specially designed and processed flexible diaphragm to replace the piston, and is driven by a driving mechanism to achieve Reciprocating motion completes the suction and discharge process.
Due to the isolation effect of the diaphragm, the structural isolation between the metered fluid and the driving lubrication mechanism is truly realized. The medicine is fully enclosed during the transportation process and will not come into contact with any objects, so it will not cause pollution or corrosion to the outside world, making the The entire dosing process is extremely environmentally friendly.
The RX-GMJ intelligent dosing system can realize local operation through the touch screen on the local control box; at the same time, the RX-GMJ intelligent dosing system has a networking function and can also realize remote monitoring and remote control operations.
　　2. Intelligent design of dosing system
1. System model construction
The intelligent dosing system is constructed in a three-layer model: the bottom layer uses a diaphragm metering pump as the dosing output control unit to accurately control the dosing output; the middle layer uses a control system to control the dosing of the bottom metering pump and the dosing pump. Carry out fault monitoring; the upper layer uses computers and industrial networks to manage the dosing system, and perform intelligent optimization data processing of the dosing system (a touch screen is configured on site to facilitate on-site operation and settings).
2. Intelligent analysis and calculation of dosage
The intelligent dosing system quickly analyzes and processes the production process data retrieved in real time from the mineral processing automation control system to achieve intelligent identification of the amount and minerality of the ore entering flotation.
Therefore, based on the amount of ore entering the flotation, the mineral properties and the dosage of the unit pharmaceutical component as required by the process, the current dosage of the dosage is calculated, and the dosage of the dosage is calculated based on this calculation to adjust the dosage of the dosage system.
　　3. System functions and features
1. Reasonable selection of metering pumps
The dosage setting range of the RX-GMJ dosing system can be very wide (as small as 3-5ml\/min, as large as 40l\/min), or even larger. Usually we will make a better design and selection based on user requirements. .
Calculate the amount of medicine required at each dosing point based on the process requirements and medicine preparation concentration, and select the metering pump based on the principles of being technically feasible and economically reasonable.
2. Precise dosing control
Through the application of advanced metering pumps, the relative error of dosing is controlled within ±1 percentage, and the PLC control system is used to realize remote automatic control and display of the dosing amount at each point.
Compared with other dosing methods, the RX-GMJ dosing system has obvious advantages in dosing accuracy:
●The dosing error of the RX-GMJ dosing system is no more than ±1 percent, and the dosing error of other dosing machines is about 5 percent.
●Avoiding the problem of inaccurate hose deformation, broken tubes and burning of the peristaltic pump dosing method
●The single-point dosing range can be adjusted, which is better than the single-point dosing machines such as pulsating dosing machines that require replacement of components to adjust the dosing amount.
●Remote\/local switching and automatic control of each dosing point.
3. Strong self-priming ability
The RX-GMJ dosing system has a good self-priming function (non-siphoning) and carries out pressure delivery (back pressure up to 10bar).
Compared with traditional dosing machines, the dosing flow rate of the RX-GMJ dosing system is not affected by the liquid level of the dosing tank, and the installation position of the equipment can be high or low, overcoming the shortcomings of solenoid valve dosing that requires the use of height difference self-flow. .
4. Historical data query and report generation
The dosing system has the function of accumulating the amount of dosing, enabling the generation of drug usage reports; and the ability to query historical data on important dosing parameters.
