When the liquid level in the lime storage silo preparation tank rises to a high level, the water inlet solenoid valve is closed, and the vibrator, star feeder, and screw conveyor stop working at the same time.
(1) When the solution in the lime storage silo preparation tank is in the neutral position, the lime silo circulating pump supplies the liquid to the metering tank, and then the dosing pump is transported to the point of use.
(2) This operating device can be operated both locally and remotely. When an emergency occurs, local or remote operation can immediately terminate the dosing process.
(3) When the system fails, the dosing will be terminated immediately and the fault light will be on. Restart dosing after troubleshooting.
(4) When the material level of the storage bin reaches the low material level, the dosing will be automatically stopped, the low material level alarm light will be on, and the dosing will be restarted after the material is added to the storage bin.
(5) The magnetic flap level gauge provides 4-20mA, analog signal to the central control room.
The automatic control can be remotely controlled in the main control room or on-site in the on-site control cabinet. During commissioning, the frequency converter and flow meter manually adjust the feeding volume and water volume, and operate normally after confirmation.
1. Manual control
In the manual control state, all the devices can be started individually by using the control cabinet buttons.
2. Automatic control
When the liquid level in the lime storage silo preparation tank is at a low level, the water inlet solenoid valve is opened to feed water into the lime silo preparation tank, and at the same time the vibrator, star feeder, and screw conveyor start to work to feed the lime material The ingredients in the silo preparation box and the vibrator work are mainly to prevent the agglomeration of lime and to evenly feed the star feeder.
