Abstract
The invention belongs to a technology for reducing metals through electrolysis and proposes an electrolysis device for recycling lead from lead paste, which mainly consists of an electrobath (1), an anode and a cathode; the cathode is arranged under the anode (5) and can be used as moving structure, namely that the cathode provided with a compound can move oppositely to the electrobath and the anode. In the invention, cathode disks provided with the compound (a mixture which mainly consists of PbO and Pb) to be electrolyzed are arranged on a rolling roller formed by a rolling shaft from the arranging opening of the cathode disks; the cathode disks move from one end to the other end at the lower side of the anode under the effect of the rolling shaft and move to the other end of the electrobath under the situation of continuous electrolysis; then the cathode disks are taken out from the taking opening of the cathode disks, namely that a plurality of cathode disks are continuously arranged in turn to move for accomplishing the electrolysis and then are taken out in turn; the whole process is simple and is easily grasped and opened; besides, the electrolysis efficiency is improved.
Description
Technical field
The invention belongs to the electrolytic reduction alloying technology, mainly propose a kind of plumbous electrolyzer that from lead plaster, reclaims; This electrolyzer is particularly useful for the PbO in the waste lead accumulator, PbO
2, Pb (OH)
2, PbSO
4Be electrolyzed to produce metallic lead in the mixture of forming.
Background technology
The existing method that reclaims lead from waste lead accumulator has pyrogenic process, wet method and wet method, pyrogenic process integrated process.Producer mainly adopts pyrogenic process both at home and abroad, and this method rate of recovery is low, and environmental pollution is serious.Wet method has rate of recovery height, characteristics such as environmentally safe.
Hydrometallurgic recovery is divided into LE method and solid phase electrolytic process two classes.LE method is to obtain the dissoluble lead thing (as Pb (BF by series of process
4)
2, PbSiF
4) the aqueous solution, in electrolyzer, carry out electrolysis and obtain metallic lead.The solid phase electrolytic process is with PbO, PbO
2, Pb (OH)
2, PbSO
4Be placed directly in and carry out electrolysis on the negative electrode and obtain metallic lead in the mixture of forming.The solid phase electrolytic process is compared with lixiviation process has advantages such as technology is simple, electrolytic current density is big, but the shortcoming when simultaneously also having the negative electrode production costs.The method that provides as certain patent (88103531) is reduzate and water and paste to be mixed in proportion make the paste spread type negative electrode, fit together and place electrolytic solution to carry out electrolysis with wringing fit structure formation it and dividing plate, negative electrode again, be negative electrode, dividing plate and anode assembling back many-one to be risen insert electrolytic solution and carry out when electrolysis, take out together again after the electrolysis, have not easy to operate and inefficient defective.
Summary of the invention
The objective of the invention is to propose from lead plaster, to reclaim plumbous electrolyzer, make and reclaim plumbous operation and become simple and convenient and enhance productivity.
The present invention finishes the technical scheme that its invention task taked: electrolyzer mainly is made of electrolyzer, negative electrode and anode, and wherein, negative electrode is positioned at the anodic below and is removable frame, and the negative electrode that compound promptly is housed can move relative to electrolyzer and anode.
Described negative electrode is made of back up pad, the axis of rolling and cathode disc, and the back up pad that wherein is fixed on the electrolyzer has a plurality of short slots, and the axis of rolling is positioned at short slot and constitutes the rolling carrying roller that cathode disc is moved, in be placed with compound cathode disc be positioned on the axis of rolling.
The cathode disc that is positioned on the axis of rolling has latticed conductor.
Anode is rectangular shaped rim and has the latticed conductor that connects with frame in frame.
Anode is rectangular shaped rim and has the strip conductor that connects with frame in frame.
Electrolyzer working process of the present invention: will be equipped with by the cathode disc of electrolytic compound (based on the mixture of PbO, Pb) and put on mouthful rolling carrying roller that is put into axis of rolling formation from cathode disc, cathode disc is moved to the other end by an end below anode under axis of rolling effect, under the situation of continuous electrolysis, move to the other end of electrolyzer, take out this cathode disc from the cathode disc conveying end again, be that a plurality of cathode discs are put into successively continuously, move and finish electrolysis, take out successively, whole process simply is easy to grasp operation, and has improved electrolytic efficiency.
