Abstract

272,047. Sansaricq, M. L. June 21, 1926. Strainer separators; driving. - A number of strainer separators are arranged about the axis of a centrifugal machine and each is rotated about its own axis as well as the machine axis. The apparatus can be used for the separation of sugar from molasses or any other similar purpose. The strainer drums are supported by arms 33<1> on a sleeve 33 at the bottom end of the hollow shaft 1; the upper end of the shaft is supported on ball bearings carried on the beam 9. A spindle 16 passes through the hollow shaft 1 and carries a bevel wheel 38 which engages toothed wheels on the strainer drums. The spindle 16 is operated from a disc 14 rotating with the shaft 1 by means of a friction wheel 23 and bevel gearing 19, 18. The rate of rotation relatively to that of the of the shaft 1 can be varied by moving the wheel 23 radially inwards or outwards over the disc 14 bv means of the guide 24 operated by the handle 32. The shaft 1 is driven by the belt 11. The external wall of each strainer drum consists of a perforated metal plate 46; inside this is a body 47 of wide wire netting, a body 48 of fine wire gauze or filter cloth, and then a cage consisting of bars 49 and rings 50. Each strainer contains a drum 51 partcylindrical in form with closed ends; it conforms closely to the cage 49, 50 and is supported by a radial arm from the central standard of the machine. An annular trough 53 is secured to the sleeve 33 and receives the material from the supply pipe 56. This material passes into the strainers through pipes 54 and the solid material remains encrusted in the grating 49, 50 at the same time travelling behind the drum 51 during part of each revolution and travelling down the drum during its treatment until it is discharged at the lower end. In a modification the retention drum 51 is replaced by a semi-cylinder 57, Fig. 13. Loose pinions 59 supported in brackets at each end of the cylinder 57 support chains 60 carrying an endless belt with slots 61. The chains are geared with crowns on the strainers to keep the belt moving.
