Abstract
An anodic steel claw for preventing denudation relates to a structural component of aluminium cell, comprising a steel claw with claw heads. The neck of each claw head is provided with an annular groove where is felted with an insulation layer whose surface is level with the outside circumference of the claw head; the outside circumference of the insulation layer is provided with firebricks. The anodic steel claw for preventing denudation of the utility model has the advantages of long service life, low price, and convenience for use.
Description
The utility model is put it briefly and is related to a kind of structure unit of electrolyzer, relates in particular to the structure unit of aluminium cell anode.
Aluminium cell prebake carbon piece anode steel jaw has conduction current and two kinds of functions of carrying carbon piece.In prebake electrolysis production operational process, anode block is because of constantly consuming attenuate, press to a certain degree after, electrolytic solution just may etch to anode steel jaw, and produce electrochemical reaction, make it to dissolve scaling loss, so just limited the operating limit of prebake carbon piece.After carbon piece thickness is determined, in order to prolong the life cycle of carbon piece,, rationally increase the carbon piece amount of pressing guaranteeing that the steel pawl is not soaked by ionogen under the molten situation, reducing anode scrap thickness is unique possible method.Therefore guarantee that anode steel jaw is not to increase the carbon piece amount of pressing by the scaling loss etch, prolongs the carbon anode key in work-ing life.No. 91218895 patent disclosures a kind of aluminium cell anode steel pawl that has carbon protective ring, make that the life-span of anode block is prolonged.But when being to use this steel pawl, anode block of every replacing just must be changed one time carbon protective ring simultaneously, very tired fiber crops, and the cost height, labour intensity is big.This anode steel jaw rigidity is poor, and is yielding under the electrolysis process state, still very big to the workload of its reparation.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of life-span long, and price is low, anti-corrosion anode steel jaw easy to use.
The utility model is prevented the corrosion anode steel jaw, comprises the steel pawl that has the pawl head, and wherein the neck at described each pawl head is equipped with the refractory brick ring.
The utility model is prevented the corrosion anode steel jaw, and wherein said refractory brick ring is made of two semi-rings, and they are linked together by " U " shape web member.
The utility model is prevented the corrosion anode steel jaw, and wherein said refractory brick ring is made of the semi-ring of two band ear handles, and ear handle is provided with pin-and-hole, passes the pin that is used for fixing described refractory brick ring in the described pin-and-hole.
The utility model is prevented the corrosion anode steel jaw, and the neck of wherein said pawl head is provided with annular recesses, is bonded with insulation layer in described groove, and its outside surface is concordant with pawl head outer circumference surface.
The utility model is prevented corrosion anode steel jaw, the dark 3mm of wherein said annular recesses, high 100mm.
The utility model is prevented the corrosion anode steel jaw, fills refractory paint between two semi-ring butt joint slits of wherein said refractory brick ring.
The utility model is prevented the corrosion anode steel jaw, is provided with heat-resisting reinforcing bar in the wherein said refractory brick ring.
The utility model is prevented the corrosion anode steel jaw, at the pawl head excircle of anode steel jaw the refractory brick ring is housed, and when having guaranteed that the carbon piece reaches operating limit thickness 140～150mm, the pawl head is not by electrolytic solution etch, oxidation or scaling loss.Promptly increased the anode block amount of pressing, reduced anode scrap thickness, made prolong 2～3 days the work-ing life of anode block.And when changing anode block, needn't change the refractory brick ring, and promptly the refractory brick ring is compared with the carbon protective ring of No. 98251702.5 patents and is had reusable superiority, so its cost is low, and labour intensity is low.Again because the refractory brick ring is anti-oxidant, erosion resistance is strong, good thermal shock, so the anti-corrosion anode steel jaw intensity of the utility model is good, and not yielding under the electrolysis process state, reduced the workload that anode steel jaw is repaired, saving of work and time is increased work efficiency.
