Abstract
Abstract A mixing tank for mixing a powder or liquid in a carrier liquid having a mixing compartment and a discharge compartment separated by a weir into which the mixed liquid overflows. The mixing compartment contains a nozzle adapted to project a film of liquid around its entire periphery. The nozzle is mounted near the bottom of the compartment and below the liquid level and directs the liquid film outwardly and downwardly to agitate the liquid in the compartment and to prevent deposition of the powder or precipitate onto the bottom.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
Mixing apparatus comprising a tank having bottom and side walls and having a divider separating the interior into a mixing compartment and a discharge compartment, and forming a weir over which the liquid flows from the mixing compartment to the discharge compartment, means including a fixed nozzle disposed below the liquid level in said mixing compartment extending vertically from the bottom of said mixing compartment centrally thereof and being provided with a deflector plate extending transversely thereof, said nozzle being adapted to discharge liquid radially and downwardly around its periphery and into the liquid in said compartment for agitating the same, and means withdrawing the liquid from said discharge compartment.
Claim 2
Dependent Claim
110 words
Mixing apparatus comprising a tank having bottom and side walls and having a divider separating the interior into a mixing compartment and a discharge compartment, and forming a weir over which the liquid flows from the mixing compartment to the discharge compartment, means including a fixed nozzle disposed below the liquid level in said mixing compartment extending vertically from the bottom of said mixing compartment centrally thereof and being provided with a deflector plate extending transversely thereof, said nozzle being adapted to discharge liquid radially and downwardly around its periphery and into the liquid in said compartment for agitating the same, and means withdrawing the liquid from said discharge compartment.
