Title: Apparatus for the continuous extraction of material
IPC: C11B1/10
Filed: 1934-03-06
Abstract: <PICT:0418725/III/1> An apparatus for the continuous extraction of raw materials with a solvent consists of two concentric extraction chambers through which raw material is conveyed in countercurrent with the solvent.  A receptacle 1 is provided with an inner concentric cylinder 2 forming extraction chambers A, B which are in communication at the bottom through a chamber C formed by a conical member 1<11>.  The cylinder 2 is mounted on a hub member 5 rotated by gearing 9, and is provided with an external feeding screw 13.  A second feeding screw 12 is mounted on a hollow shaft 6 which is rotated by gearing 11.  The two feeding screws are thus rotatable at different speeds whereby the rate of extraction may be regulated.  In operation, the raw material such as oil seeds is admitted to an opening 20 and feeding elements 24 pass the material into the annular chamber A.  The material is conveyed downwards by the screw 13 to the chamber C from which it is raised by the screw 12 through the inner chamber B.  Solvent is admitted through a pipe 22 to nozzles 23. Above the nozzles 23 the inclination of the screw blades is decreased whereby a slight squeezing of the extracted material is effected to remove the extract, and also prevents the fresh solvent from progressing upwards.  The extract passes through openings 1<1> in the upper wall of the chamber A, which are at a lower level than the inlet nozzles 23.  Extracted material passes through an opening 14 to a chamber 15 from which it is removed by rotating vanes 16 to an outlet 26.  The apparatus may also be used for extracting wood bark or wood dyes.

[Class 78(i)] [Also in Group XXXII] Means for coupling a port able excavating and convey ing apparatus to a vehicle comprises a pair of thrusting members rigidly attached to the frame of the apparatus and terminating in forks which serve to guide these members into engagement with stops on opposite sides of the vehicle chassis, an auto. matic coupling means on the vehicle for engagement with a member carried by the ap paratus to hold the thrusting members in engagement witt the stops whereby the appara. tus responds to every movement of the vehicle wher coupled thereto, means operable from the vehicle for releasing the coupling, and outwardly curved guiding members on the vehicle chassis adapted to engage with said forks if the vehicle and apparatus are out of alignment and thereby assist in guiding the thrusting members into engagement with the stops as the vehicle approaches the apparatus. In the embodiment shown, a portable elevator frame 1 is connected to a truck 3 into which material is delivered from a heap'9 9 by an elevator comprising endless chains 6 supported on. rollers 5 and driven through gearing 11 by a power unit 10. Scraper blades 7 on the chassis remove material from the heap 9 and push it up a trough 2 to an extension 2a from which it falls into the truck. The frame normally rests on castors 22 and the lower' end of the trough 2, but when the truck is backed to engage it, stops 14 on the chassis frame engage fork-members 13 on arms 12 at'the sides of the frame 1 whereby these are depressed slightly so as to tilt the frame, about the castors 22 and lift the lower end of the trough 2 off the ground. At the same time the truck is coupled to the frame by a gravity or spring loaded catch 16 engaging over a bar 17 extending between the arms 12. The catch may be withdrawn to disconnect the frame by a handle' 21. If the truck and the frame are not in alignment when the truck is backed, the forks 13 are guided laterally into alignment with the stops 14 by guides 15 secured on the truck. The castors 22 may be adjusted vertically relatively to the frame 1. The blades 7 may be inclined transversely to the chains 6 and to stimulate the loosening of the material to be excavated, tines may be interspersed between the blades. The blades may be cleaned by a stripper device 25, Fig. 3, carried on bars 26 pivoted at 27 on the frame 1 and normally held retracted by a spring 28. As each blade passes the extension 2a, it contacts near its root with the stripper-bar 25 which then moves down the blade to scrape off any material adhering to it. On reaching the dotted line position in Fig. 3 it is brought back to its original position by the spring 28.
