Embodiment Construction

[0041] As a non-limiting example, the following describes a counterpressure device for a vertical vibratory compactor or a vertical vibratory compactor for extracting, inter alia, from liquid bitumen and A slurry consisting of crushed coke is formed into molded anode plates. However, the counterpressure device of the present invention is applicable to any other vertical vibratory compaction device for pellets or any other machine within the scope of the present invention.

[0042] As mentioned above, as shown in FIG. 1 , a machine for forming anodes by vibratory compaction according to the invention generally comprises a mold 1 generally in the shape of a parallelepiped with a rectangular cross-section, and an indenter 3. The model 1 is open at its two opposite horizontal end faces, namely its bottom face and its top face, and is detachably fixed on the vibrating table 2 constituting the base of the model 1, and the indenter 3 can be inserted through the top face of the model ...

Abstract

The invention relates to a back-pressure device (12) for a vibrocompacting device, particularly for forming molded carbon blocks, including: at least one mold that is open on two top and bottom horizontal surfaces thereof and securable to a vibrating table forming the bottom of the mold and subject to vibrations by an actuating means; a pressing weight (3) capable of being placed in the mold; and a cover (13) capable of sealingly closing the top surface of the mold. Said back pressure device (12) is characterized in that it does not have a central cylinder stack and includes two stacks (16) or sets of stacks of inflatable cylinders (17a, 17b) that are symmetrically and laterally eccentric on both sides of the central vertical axis (VV) that engages with a guide means (18) that is suitable for each stack (16), the top end of the top cylinder (17a) and the bottom end of the bottom cylinder (17b) of each stack (16) being respectively secured to the cover (13) of the pressing weight (3). The invention also relates to a vibrocompacting device provided with a back pressure device according to the invention.

Description

technical field [0001] The present invention relates to a vibratory compaction device especially for molding carbon blocks from a slurry of liquid pitch and crushed coke for the manufacture of electrodes, in particular anodes, for electrolytic aluminum and which is equipped with a counter pressure device . Background technique [0002] Known vibratory compaction devices basically consist of a former generally in the shape of a parallelepiped with a rectangular cross-section and movably mounted on a vibrating table constituting the base of the former, and an indenter adapted to pass through the The upper end of the form is inserted axially into said form. The vibrating table is connected to the frame through the suspension device, and is subjected to vibration along the axis of the model in a substantially vertical direction under the action of the vibration actuating device. [0003] This is especially the case of patent US 3,767,351, which describes a device for the manuf...
