Abstract: 190,727. Dorr Co., (Assignees of Stedman, W. A.). Dec. 22, 1921, [Convention date]. Solids, treating with liquids.--In treating solid and liquid mixtures, discharge of thickened material from the body of the pulp is automatically effected, in response to the rate of accumulation of solids therein, by opposing the hydrostatic pressure of the discharging solids by a pressure obtained from a pulp of less density such as a mixture of discharged material and a liquid diluent. Applied to a settling tank 5 of the Dorr thickener type, having a launder 6 for removing clear solution by decantation, and slime collecting mechanism with radial arms 10 provided with scrapers 11, the apparatus comprises a trap consisting of a cylindrical vessel 13 and a tube 15 depending from the slimes outlet nearly to the bottom of the vessel. An outlet pipe 16, with discharge end provided with an adjustable sleeve 17, leads from the upper part of the vessel, overflow thereupon being received in a basin 18 with discharge spout 19. A pipe 20 for introducing diluent enters the vessel about midway between the top and 'bottom and is bent at the outlet to cause the issuing liquid to swirl round the annular space and dilute slimes rising above a level somewhat above the lower end of the tube. The column of liquid in the pipe 16 balances the column of combined solids and solution in the tank and trap, and by adjustment of the height of the sleeve 17 the depth of slimes in the tank 5 can be maintained at anv desired level. Fig. 3 shows a three-compartment apparatus having pipes 40, 40<1>, 40<11>, supplying diluent and overflow pipes 43, 44, removing clear solution from the two upper compartments. diluted slimes being removed from the lowest.
