Application Of Rotary Lobe Pump In New Energy Battery Slurry Industry

In recent years, the new energy battery industry has grown rapidly. By 2025, the battery industry will also increase its capacity by about five times.

Battery slurry conveying process design equipment and devices are transfer pumps, filtering devices, dispersion devices, storage tanks, etc.. Among them, the key equipment transfer pumps are screw pumps, gear pumps, lobe pumps and many other types, but considering the slurry has abrasive lithium iron phosphate and other powders, but also acid and alkali, organic solvents and other highly corrosive components, strong abrasion, viscosity up to tens of thousands, and the temperature can be as high as 100 degrees, so the requirements of the battery slurry transfer pumps are very high.

A comparison shows that lobe pumps have clear advantages in the manufacture of lithium batteries. The lobe pump is particularly suitable for the transport of mediums that are prone to foam as well as high viscosity, consistency and any media containing particles. The output pressure and flow rate are stable. The material conveyed by it remains unchanged in its original quality, without shear and without any physical or chemical reaction.

Advantages of Ace lobe pumps for transferring battery slurry.

1、No need to fill the pump manually, that is, it has a strong self-priming force, the maximum suction range is 8.5m; conveying flow range 1-2000m3/h.

2. The maximum medium viscosity is 100,000 cp and the maximum solids content is 60% of the slurry.

3. Forward and reverse rotation is possible, suitable for loading and unloading scenarios.

4、The non-clogging design ensures the passage of large diameter materials, with a maximum passage diameter of 80mm.

5、Triple flow precision casting mould and five-axis linkage process empowered with the pump, making it highly efficient, energy saving and low noise.

6. The double support structure allows the pump to run more stably and the output pressure can be up to 1.8Mpa.

7、Smooth conveying, small pulsation, low shear force, can convey mixed media of gas, solid and liquid as well as media sensitive to truncation.

8、The extractable design of the back cover allows maintenance without dismantling the pump body and piping.

Ace lobe pumps in the battery slurry industry

Highly accurate supply of electrode material for a more uniform coating thickness.

Pulsation-free dosing even with highly concentrated slurries, regardless of viscosity. Helps to achieve a more uniform film thickness for precision film coating. Easy to use and versatile as the spout volume can be adjusted by simply controlling the rotation speed.

Powerful attraction even under high vacuum conditions

Through the attractive force generated by the rotor during rotation, high viscosity liquids or highly concentrated slurries can be strongly drawn in and dosed even under high vacuum conditions.

Improving the homogeneity of slurries

The liquid material is supplied to the dispersion unit in a pulsation-free and dosed manner to improve the dispersion of micro particles. The flow rate can be easily adjusted to the capacity of the dispersion unit.

The lobe pump not only ensures the quality and performance of power battery production by quantitatively transporting cathode material, cathode material and electrolyte without pulsation, but also provides excellent durability and ease of maintenance, meeting the high standards and requirements of battery production sites that pursue strict management.
