Title: An apparatus for continuously mixing together a liquid and one or more substances
IPC: C13B20/02
Filed: 1950-08-22
Abstract: 674,794. Mixing appliances. AKTIESELSKABET DE DANSKE SUKKERFABRIKKER. Aug. 22, 1950 [Aug. 24, 1949], No. 20760/50. Class 86. Apparatus for continuously mixing together a liouid and one or more substances, under conditions in which the substance or substances are progressively added so that their concentration in the liquid increases substantially uniformly, comprises an elongated vessel along which the liquid flows with means at one or more points along its length for adding the substance or substances and stirring means for imparting transverse rotary motion to the liquid and shutters inclined in such a manner as to return some of the liquid containing a concentration of substance or substances to a zone longitudinally upstream where the concentration is relatively lower. As shown in Fig. 1, an elongated vessel 1 is provided with transverse partitions 2 forming chambers 3 to 8, in each of which chambers a set of stirring blades 10 is carried by means of a rotatable shaft 9. Above each partition is a shutter 15, which is of a length to extend substantially across the width of the vessel and which is angularly displaceable about a vertical central axis. In operation, as described in a process of liming diffusion juice obtained in the extraction of sugar beet, the diffusion juice is fed in through a pipe 18 and the treated juice is removed through an outlet 20, liming composition being continuously fed through a pipe 19. The rotation of the stirrers causes a circulation of the contents about the axis of the shaft 9 and the shutters are set at an angle such that some liquid in each chamber will be deflected back to the next chamber nearer the inlet and in this way the concentration of liming composition in the juice is caused to increase as the outlet is approached. The shutters can be employed unassociated with partitions and several relatively long vessels thus equipped may be connected in series with or without provision for liquid return between individual vessels.

A steering-column-mounted hand shift-lever 8, operates the sliding and turning. selector-shaft 30 of a 3-speed and reverse vehicle changespeed gear through a shift-rod 9 mounted parallel to the column to slide and turn on fixed axial pins 12, 15 on the column, the pins having spherical enlargements, that 17 at the upper end providing a fulcrum for the hand-lever 8 which latter has a pin 20 engaging the outwardlyturned forked end of the rod 9, whilst the enlargement 18 at the lower end fulcrums an arm 23, levered by an offset ball-end 22 of a curved finger 21 at the cranked lower end of the rod 9. A link 25 rigidly connects the arm 23 with a similar arm 31 which fulcrums on a ball-ended fixed stud 27 and is engaged by a ball 28 on an arm 29 fast to the gear selector-shaft 30. Selecting movement of the hand-lever 8 in the plane of the column thus moves the rod 9 axially in the same direction, swinging the lower arm 23 in the same plane and, through the link 25, swinging the arm 31 perpendicular to the gear selector-shaft 30 and thus moving the latter axially, whilst rotary movement of the lever 8 about the axis of the rod 9 turns the latter and the arm 23 about the same axis, which, through the link 25 turns the arm 31 about the axis of the gear selector shaft 30, thus turning the latter to establish a gear. A spring 52 in the upper end of the rod 9 biases the lever 8 downwards into the 2nd and high plane, and springs 24 load the ball joints. Gear shift arms 37, 39, Fig. 4. are journalled on the selector-shaft and clutched selectively thereto by a diametral pin 41 on the shaft engaging notches 43 in the adjacent end faces of the arms when the shaft slides axially for selection. That arm 37 or 39 not locked to the shaft 30 is locked against all movement by a ball 44 or 45 engaging a recess in the arm and released by a shaft-groove 47 or 48 when the shaft 30 is moved axially to clutch the appropriate arm. The usual spring detents retain the arms 37, 39 in set positions, Fig. 5 (not shown).
