Lime dosing device automatic feeding storage tank

working principle
The automatic dosing device of lime lotion and dry powder is used to store a certain amount of lime powder (Cao, CaoH) (through negative pressure suction, blow in by material transport vehicle, input by screw conveyor, and manual pouring) in a special container (lime silo). The powder dust generated when the powder is put into the silo is collected by the bag dust collector, and the dust absorbed on the surface of the bag is vibrated by the vibrator to fall back to the powder silo. The stored lime powder is loosely and evenly fed to the variable frequency speed regulating feeder for quantitative feeding (dry powder feeding process) through the oscillator. The screw conveyor is transported to the lime milk dissolving tank, and lotion is generated by mechanical mixing. The liquid medicine feeding pump is used to transport the lotion with a concentration of 5% -10% to the liquid medicine feeding point (lotion feeding process).

The system is fully controlled by PLC program and displays the material level; Display of high, low, and low liquid levels, with the system shutting down when the liquid level is low and automatically running when the liquid level is low; The concentration of the medicinal solution is controlled by adjusting the frequency of the frequency converter to control the speed of the feeder motor to achieve quantitative feeding; Shutdown is controlled by the program for practical system cleaning.

In the process of treating acidic wastewater in water treatment systems, lime is commonly added after neutralization and pH adjustment. The dosing process requires strong continuity, and manual dosing is labor-intensive. In order to meet market demand, we are now providing a lime milk dosing device with simple equipment operation, continuous dosing, and stable dosing amount to the environmental water treatment market.

1.1 Working principle

The lime milk dosing device is a device for storing, preparing, and dosing quicklime powder. Lime powder is stored in the lime silo and evenly fed into the feeder. The spiral conveyor feeder sends the lime powder into the dissolution tank for dissolution. The dissolution tank mixer thoroughly stirs the solution, and the prepared solution is pumped by the lime milk pump to the user's point of use.

1.2 Product Features

1. Basic entry and exit capacity: The storage capacity of the powder silo ranges from 20m3 to 500 cubic meters;

The preparation concentration of lime lotion (lime emulsion) is about 5% -10%.

2. The use of a feeding oscillator can make lime feeding smoother.

3. Continuous and fully automatic preparation, powder feeder with speed regulating device, wide range of feed volume adjustment, high precision of lime lotion concentration preparation.

4. Optional vibrators or arch breakers can make lime feeding smoother.

5. The volumetric quicklime digestion device used can adjust the relationship between the feed rate and inlet water rate reasonably, adjust the most suitable digestion temperature, and make the quicklime digestion more efficient and efficient.

6. The lime pipeline valve adopts a special pipe valve, which is unobstructed, leak free, and easy to operate and control, especially suitable for the transportation of process materials containing particles.

7. The level gauge adopts imported liquid level measuring instruments for control.

8. The electronic control system adopts an automatic control system, and the equipment operates automatically.
