摘要： In an apparatus for classifying objects by sedimentation having a straightening passage, capable of being prevented adhesion of bubbles to the straightening passage, and capable of being prevented a sample supplying error generated caused by a closed sample supplying portion on account of air locking, there is provided a bubble-removing passage for removing the bubbles within fluids at upper stream position of a straightening mesh within a classifying bath for classifying objects based on dropping position caused by a final sinking velocity of said objects falling within fluids after throwing said objects into flowing fluids, the bubble-removing passage which comprises a filter and a filter holder secured within the classifying bath through a protuberance.

摘要： A method for classifying sand wherein a mixture of sand and water is introduced into a classification tank (7) partially filled with water. Depending on the weight of the sand grains, the grains of sand will precipitate at the bottom (8) of the tank (7) at graduated distances from an inlet pipe (6), the heavier particles nearest the inlet and the lighter particles farther away.To prevent large quantities of fines, i.e., sand grains between about 0.002 mm and 0.006 mm in size, from being lost by being washed out of the tank (7) together with the overflow water, the water from the tank (7) is recirculated by means of a pump (14) so that the water becomes progressively more saturated with fines, which means that larger amounts of fines will precipitate in the tank (7).Because the water is recirculated, water consumption can be reduced by 2/3, and at the same time the problem of the overflow water from the tank (7) is also reduced.

摘要： A device for separating and recovering solid particles or granulated matel from a stream of fluid in a state of high purity and with minimal fluid remaining in the recovered solids. The device also provides a calibration or sizing of the recovered solids. More particularly, the device is suitable for recovering sand and gravel from a liquid slurry in dredging operations or the like and comprises a chamber into which the slurry is discharged in the form of two diametrically disposed impinging jets to decrease the kinetic energy of the slurry. The chamber is provided with one or a plurality of outlets disposed in communication with a corresponding number of channels each having a discharge port in the base thereof and a deflector in the discharge port, preferably disposed at an angle of about 45 degrees, for directing the concentrated lower layer of slurry in each channel through the discharge port into a deposition tank. Preferably, a plurality of deposition tanks are employed disposed in series for receiving the overflow from the downstream tank to effect recovery and classification of the recovered particulated solids.

摘要： A method and apparatus for separating a mixture of cation and anion resins is disclosed. The separation involves introducing the mixture of cation and anion resins to a treatment zone in countercurrent flow with a carrier fluid to achieve hydroclassification of the resins. The method and apparatus may be employed to separate cation and anion resins on either a batch or continuous basis.
