Definitions
- the present invention relates to a vibro-compaction compaction device, particularly intended for forming carbonaceous blocks molded from a paste of liquid pitch and crushed coke, for producing electrodes, in particular anodes, for the electrolysis of the aluminum, and equipped with a back-pressure device.
- Vibro-compaction compaction devices are known essentially comprising a generally parallelepipedic mold of rectangular cross-section removably mounted on a vibrating table constituting the bottom of the mold and an pressing mass capable of being introduced axially into said mold by an upper end of the mold.
- the vibrating table is secured to a frame by means of suspension means and is subjected to vibration in a substantially vertical direction, along the axis of the mold, under the effect of vibration actuating means.
- Such a known device represented in FIGS. 1 and 2a of the present application, is then essentially constituted of a mold of parallelepipedal general shape of section rectangular cross-section 1 of substantially vertical axis, movable vertically, and removably mounted on a vibrating table 2, and a pressing mass 3.
- a paste 4 composed of liquid pitch and crushed coke
- the pasty mixture is compacted under the effect of the hammering of the pressing mass 3.
- the bent trees 5 rotate in opposite directions and induce an excitation in the table 2 which then takes a vertical sinusoidal movement.
- the table 2 is installed on an elastic suspension 6 to limit vibration transmissions to the ground 7 and / or in the vicinity of the device.
- Said mold 1 is conventionally mounted on guides 9a, sliding vertically in sleeves 2a integral with the table 2, and is actuated by hydraulic cylinders 10 connected by the free end of their rod to the mold 1 and by the lower end of their cylinder to the table 2, said hydraulic cylinders 10 performing the clamping functions of the mold 1 on the table 2 and demolding, by lifting the mold 1 above the table 2 to allow the lateral removal of a molded block of the above the table 2.
- the compaction device comprises a system for evacuating the inside of the mold 1 and a so-called backpressure device 12 integral with a lid 13 sealingly closing the upper part of the mold 1 by means of mechanisms 15 removable closure of the cover 13 on the mold 1 (see Figure 1), the cover 13 being movable vertically with the pressing mass 3 relative to the mold 1 by external means 11 such as a winch or a hydraulic cylinder with suspension rod, associated the evacuation system of the mold 1, and subject to a frame (not shown), being guided by vertical guides 9b of the cover 13 in the sleeves Ib secured to the mold 1. Said cover 13 seals the mold 1 and provides support for the back-pressure device 12 which pushes the pressing mass 3 towards the paste 4 and the table 2.
- the back-pressure device 12 comprises expandable devices, generally pneumatic cylinders 14, which are installed between the cover 13, against which they bear, and the pressing mass 3, they push down.
- These pneumatic cylinders 14 have their upper and lower bottoms respectively secured to the lid 13 and to the pressing mass 3 and are inflated with compressed air during all or part of the compaction phase, the source of compressed air not being shown in the figures.
- FIG. 2a shows a counter-pressure device 12 already made consisting of two pneumatic cylinders 14 arranged symmetrically on either side of the rod 11 for suspending the pressing mass 3 and the cover 13.

- this type of stack of pneumatic cylinders has the disadvantage of being unstable and buckling under load from a certain critical height.
- buckling is meant the phenomenon by which the average line of the stacked pneumatic cylinders deviates from the vertical straight line. Under the effect of this phenomenon of buckling, the pneumatic cylinders become asymmetrical and generate lateral thrusts which are particularly detrimental to the compacting efficiency of the device.

- the plate 12b guided on the suspension rod 11 can not move in a horizontal plane, it is free to rotate around the same rod.
- the cylinders 14 of the two lateral stackings finally have complete freedom to flambe.
