A spacer for electrodes has pair of walls which define a channel for an edge of an electrode. An arm extends from an edge of each wall, and the arms include respective sections which flare to opposite sides of the channel. Each arm can include an additional section which extends from the associated flaring section and is inclined towards the opposite wall.

Spacer for electrodes

An electrolytic processing tank contains alternating cathodes and anodes. Each anode carries a sealing unit on either side thereof. The sealing units include flexible U-shaped sealing members which are in surface contact with neighboring cathodes. A sealing member which is T-shaped as seen in an end view is positioned adjacent the end of each anode. Each T-shaped member has a leg whose thickness is the same as that of the anodes, and a crosspiece which extends partway along the leg. The leg is aligned with a neighboring anode, and the end of the leg remote from the crosspiece abuts the anode. The crosspiece projects beyond the opposite end of the leg to form a flexible flap which establishes a seal with a wall of the processing tank. The crosspieces of neighboring T-shaped members overlap one another.

Preventing escape of vapor or gas from electrolytic systems

An electrode assembly for use in electrowinning includes a cathode in the form of a plate. The cathode has a pair of parallel vertical edges, and a horizontal bottom edge which runs between the vertical edges and defines respective corners therewith. An edge strip is mounted on each of the vertical edges as well as on the bottom edge. The bottom edge strip has an end at either corner, and each end of the bottom edge strip is in abutment with the lower end of the adjoining vertical edge strip. A corner protector is located at each corner and has a vertical channel which receives the lower end of the respective vertical edge strip, a horizontal channel which receives the respective end of the bottom edge strip, and a cutout which receives the cathode.

Corner protector for electrowinning electrode

An electrode edge protector that includes an elongate strip having a substantially H-shaped cross-section in combination with an expansion member. The elongate strip comprises two lever-arm portions made of rigid material that define a longitudinal edge slot for receiving and wrapping around the edge of an electrode and an opposing expansion slot for receiving the expansion member. The rigid lever-arm portions are interconnected between the slots by a coextruded hinge member made of resilient material which enhances the ability of the edge strip to adhere to the electrode in the edge slot as a result of the force exerted by the expansion member in the expansion slot.
