Assembled anode for electrochemical reaction to synthesize stannous octoate, and assembling method thereof

Abstract

The invention discloses an assembled anode for an electrochemical reaction to synthesize stannous octoate, and an assembling method thereof. The anode is formed by assembling a tin anode plate in a supporting frame; the supporting frame comprises a square tube conductive cross beam and a frame with the outer surface coated with an insulating layer, which are welded with each other, and the frame is a U-shaped tankt frame with an inward groove opening; hanging lug supports are symmetrically welded to the upper portions of two vertical frames, and a conductive copper bar and an insulating plateare installed on the bottom faces of two sides of the conductive cross beam respectively; tin anode plate side inlets are symmetrically formed in the upper parts of the front surfaces or the back surfaces of the two vertical frames, or a tin anode plate insertion notch is formed in the top surface of the conductive cross beam, or the tin anode plate side inlets and the tin anode plate insertion notch are formed at the same time; the bottom transverse frame is provided with a liquid discharging hole; and two hanging lugs of the tin anode plate are placed on the hanging lug supports. The anode residual rate in stannous octoate electrochemical synthesis can be reduced, the anode plate breaking and falling phenomena are reduced, and the production efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of anodes for electrolytic cells. Background technique [0002] In the organic electrochemical synthesis reaction of stannous octoate, high-purity metal tin is used as the anode, and the tin cation required for the reaction synthesis is obtained by sacrificing and dissolving the anode. The anode plate needs to be hung on the electrolytic cell containing electrolyte during electrolysis and ionization. In order to ensure a certain width between the side of the anode plate and the wall of the electrolytic cell, the length of the anode lugs often needs to be longer; to ensure the anode lug beam There is still a certain strength after electrolysis. Generally, the hanging ear beams will leave a certain height from the liquid surface (waterline); in order to increase the effective area of ​​the anode plate, the vertical direction of the plate is often made longer; and due to the high height Pure metal tin is soft and e...

Problems solved by technology

The anode plate needs to be hung on the electrolytic cell filled with electrolyte during electrolysis and ionization. In order to ensure that there is a certain width distance between the side of the anode plate and the wall of the electrolytic cell, the length of the anode lug is often made longer; in order to ensure that the anode lug beam There is still a certain strength after electrolysis, and generally there will be a certain height distance between the hanging ear beam and the liquid surface (water line); in order to increase the effective area of ​​the anode plate surface, the vertical direction of the plate surface is often made longer; and due to the high Pure metal tin is soft and easy to deform. In order to bear the heavy weight of the anode plate, prevent the deformation of the anode beam and the deformation and breakage of the hanging lug, and cause unnecessary troubles such as falling off the plate, the anode beam and the hanging lug must be made relatively thick. This greatly increases the weight of the anode plate, resulting in an increase in the ineffective weight of the anode plate and an increase in the rate of electrolytic residual electrodes
