Overview of the Structure
System of water supply
It is made comprised of an intake solenoid valve, a flow meter, and a pressure lowering valve to provide a smooth water supply and no significant pressure fluctuations, as well as to calculate and show inlet flow.
System for feeding dry powder
It is made up of a screw pump, a vibrator, a heater, and a material level switch. The screw pump's speed is regulated by a PLC and a frequency converter, and dry powder is added at the specified concentration. The vibrator and heater can keep the powder from becoming wet, caking, and metamorphism from occurring.
System for dry powder premixing
Three tanks in one: a mixing tank, a storage tank, and a storage tank. The ultrasonic level sensor measures the liquid level height, and the PLC controls the start and stop of the powder feeding and dosing motors.
System of dosing 
Open and prepare two frequency-controlled dosing pumps, set the motor frequency to the actual dosing volume requirements, and manage dosage size. The dosing pump must be selected manually, and the selection is invalid when the dosing pump is functioning.
System of secondary dilution
A pressure reduction valve is used to manually modify the inlet flow rate. The inlet flow rate is indicated by a plate flowmeter, and secondary dilution is performed based on liquid concentration and dosage. Install a pressure reduction valve to guarantee a steady water supply and no significant fluctuations in the pressure of the Secondary dilution system.
The solution tank, mixer, metering pump, Y-type filter, safety valve, back pressure valve, check valve, pulse damper, water level gauge, pressure gauge, control cabinet installation platform, and other components comprise an automatic dosing equipment. Installed on a foundation. Simply position the combination dosing device in the dosing room, attach the dosing tube to the power source, and begin operating. During operation, the pH of the fluid is automatically determined and the appropriate liquid is added. A comprehensive set of factory equipment can significantly decrease the labor of design and on-site building, allowing the machine to be built unattended and providing a trustworthy assurance for quality, safety, and on-site operation of the entire machine.

Automatic dosing device Submission of Applications:
1. Chemical agent dosing in acidic and alkaline environments.
2. Including chemicals in sewage treatment schemes
3. Quantitative chemical dosing in the chemical industry

Characteristics of an automatic dosing device:
1. The equipment is made of corrosion-resistant materials that have a long service life and consistent performance.
2. Automated control, the equipment may start up automatically, administering the drug quantitatively, and stopping automatically when the liquid level is low to prevent the equipment from malfunctioning.
3. Highly integrated, saving space.
