Embodiment 1

[0077] Example 1 ( Figure 2 to Figure 7 )

[0078] Figure 4 to Figure 7 Schemes are shown in four different configurations of the hydraulic circuit supplying the first drive 50 for the collection unit of the invention, which additionally has the above-mentioned ( figure 2 and image 3 )Characteristics.

[0079] The first driver 50 or lifting jack is a double acting jack 51 having a body 55 and a piston 56 to which a rod 52 is attached. rod 52 with the collection unit (not in Figure 4 to Figure 7 shown in ) connection. The double-acting jack 51 has: a rod side chamber 53, referred to as the "low chamber", capable of moving the mobile vertical rod 9" vertically upward at any time; and a piston side chamber 54, referred to as "High chamber", which at any time enables the mobile vertical rod to move vertically downward. The hydraulic circuit consists of two parts 63 supplying the two chambers 53 and 54 of the double acting jack 51 and 64. Said circuit may be connected t...

Embodiment 2

[0104] Example 2 ( Figure 8 )

[0105] Figure 8 is a schematic diagram of a collection unit in which the first driver 50 is an electric motor 53' powered by using a circuit capable of controlling the rotation of said motor. Here, the electric motor is the engine of an electric jack 51' that imparts a vertical movement on a link 52' coupled to the frame 110'. In a variant of this embodiment, the electric jack is replaced by an electric winch and the connection is a cable coupled to the frame, the vertical movement of which is guided, for example, by guide means fixed to the mobile support.

[0106] Depending on the control current delivered by the transmission 83', the electric motor 53' is always able to exert a vertical upward or downward movement on the link 52' at the desired speed. The transmission 83' is controlled by a PLC 84 which receives readings provided by two sensors:

[0107] - The first sensor indicates the distance H between a reference level N (e.g. the p...

Abstract

Collecting unit (100) of bucket shovel type, used in aluminum production ponds, comprising: a) a device fixed on a mobile support (5'); b) a link (52) driven by a first drive (50) , 52'), moving in a vertical direction relative to the mobile support; c) a frame (110) coupled to the connector; d) at least one hinged bucket (120a, 120b) around the axis (115a, 115b) Rotating, mounted on the frame, having blades (128a, 128b), and rotating about said substantially horizontal axis. The first drive (50) is connected to a programmable control system capable of determining the height of said axis and the height difference between said blade and said axis, defining the vertical movement to be imparted to the collecting unit, and defining and passing an appropriate control flow to the first drive to impart said vertical motion. The control flow can be the control current delivered by the transmission to the electric motor or the oil flow controlled by the servo distributor supplying the chamber of the hydraulic jack.

Description

technical field [0001] The present invention relates to the production of aluminum by the Hall-Héroult process using pyroelectrolysis. More specifically, the present invention relates to a device designed for collecting solid fragments submerged in or floating on electrolyte and metal liquid, especially from the electrolyte, collecting in the tank Sludge at the bottom, and especially char residues and shell fragments arising from the various operations performed before and during spent anode removal. Background technique [0002] Industrially, aluminum is produced by fire electrolysis in electrolytic cells using the well known Hall-Heroldt process. The factory consists of a large number of electrolytic cells arranged in a straight line in a building called a potroom or room and connected electrically in series using connecting conductors, thereby making the most of the factory's floor area. Electrolytic cells are usually arranged to form two or more parallel lines electric...
