Abstract

Gaseous bubbles in viscous liquid tend to dissipate only very slowly under the action of gravity. This apparatus is for increasing the effective Pressure in liquid while maintaining a free surface at atmospheric Pressure for enabling escape of the unwanted bubbles.

Viscous Liquid Devoider

Gaseous bubbles in viscous liquid tend to dissipate only very slowly under the action of gravity. This apparatus is for increasing the effective Pressure in liquid while maintaining a free surface at atmospheric Pressure for enabling escape of the unwanted bubbles.

The apparatus includes a block 10 having machined in one face circular chamber 12. This has liquid-inlet gas-outlet aperture 14 communicating to the atmosphere. The front face of chamber 12 is closed by a sheet of transparent material 16 permitting visual monitoring of the fluid level within the device.

Disk 18 is mounted for rotation around a fixed axis 20, offset from axis 22 of chamber 12. Disk 18 is of the same thickness as chamber 12 but of smaller diameter so that it fills all but a crescent-shaped segment 24 of 12. Disk 18 is rotatable about its axis 20 in direction 26, by operation of a shaft, not shown, journaled through the back of block 10.

As disk 18 rotates, its surface friction on liquid 28 within crescent 24 is such as to increase the pressure at the lower end, adjacent outlet port 30. This operates to squeeze bubbles 32 from the liquid, urging them by the greater pressure at the lower portion of crescent 24 to rise toward the free surface 34 of the liquid for escape through aperture 14.

The result is that liquid issuing from the outlet 36 of the device is substantially free of voids. From time to time or continuously, additional fluid to be treated is introduced...
