sewage treatment dosing device Manufacturer fully automatic
integrated dry powder dosing system
The three compartment integrated PAM dosing device is composed of
water supply system, dry powder dosing system, dissolution curing
system, control system and liquid dosing system.
The three compartment automatic dosing device is an intelligent,
fully automatic and continuous flocculant dissolving and dosing
device. The concentration of the prepared solution is generally
0.1% - 0.5%.
Working principle
The dosing system is automatically controlled by PLC, and the
control box is connected to the liquid level gauge installed on the
solution storage tank. Once the liquid level reaches the "low
level", the solenoid water inlet valve is triggered to open, and
the dry speculation is started at the same time. The size and
amount of dry dosage can be accurately set to obtain accurate
concentration. Once the "high bit" is reached, the cycle stops.
The whole preparation process of the dosing equipment is controlled
by PLC, which can realize the functions of automatic intermittent,
continuous operation and stop cross mixing, so as to make the
solution blend evenly. When the dry powder level in the hopper
reaches the low level, the electric control box can send out
audible and visual alarm signals and stop the whole machine.
Application
The fully automatic dosing device is safe, convenient, reliable and
widely applicable, especially to the paper industry, industrial
wastewater treatment and municipal wastewater treatment plants,
water plants and various industries that need to use flocculant
solution.

Operating Steps
Note: different plc control systems may have some differences in
operation. Please follow the manufacturer's instructions. This is
mainly for the three tank integrated dosing device.
1. Connect the power supply, pipeline and water source, and do a
good job of basic security.
2. Switch the change-over switch of metering pump of dosing pump,
inlet solenoid valve, dissolution tank mixer, and connecting valve
between raw liquid tank and dissolution tank to the "remote"
position. Adjust the stroke speed of the metering pump on site.
3. Move the floating ball of the box up and down one by one by hand
to see whether the signal can be sent normally, and then check
whether the level alarm in the hopper can work normally.
4. Return to the central control, click to enter the "dosing
system" screen, and manually adjust the output frequency of the
metering pump.
5. Open the water inlet valve and press the start button of the
feeding motor to start feeding. Stop feeding after one minute of
operation.
6. Observe the liquid level gauge. When the liquid level gauge
reaches the required height for dilution of raw solution, close the
inlet solenoid valve and the mixer. Click the icon of the outlet
valve of the dissolution tank to open the outlet valve, and click
the icon of the metering pump to open the metering pump. Pay
attention to the liquid level gauge and flowmeter. When the liquid
level is too low, turn off the metering pump in sequence and close
the liquid outlet valve.
7. Weigh the polymer in the container and make records.
8. Stop the feeder.
