Abstract

The utility model discloses an electrolytic tank. The steel frame bottom surface arranged between an inner container and a steel frame is provided with a metal plate. The four sides of the steel frame are paved with a metal net in firm welding with the steel frame. The outside of the metal net is welded with a plurality of plastic blocks with the inner container to position the metal net between the plastic blocks and the inner container. The outside of the steel frame is provided with an overall plastic shell of integral form in rivet bond with the steel frame. The interface portions of the shell and the inner container are in welded sealing. The steel frame, the metal plate and the metal net are sealed in the inner container and the shell. The utility model has high quality, good corrosion proofing performance and acid proofing performance, impacting resistance, free maintenance and long service life.

Description

Electrolyzer

Technical field:

The utility model belongs to the production facility of metallurgy industry electrolytic metal, is specifically related to a kind of electrolyzer.

Background technology:

At metallurgy industry, particularly in the hydrometallurgy, a kind of electrolyzer is to adopt overall plastic global formation inner bag is placed in antiseptic steel framed structure, there is following weak point in the electrolyzer of this structure: the one, and overall plastic inner bag can't be fixedlyed connected with steelframe, under electrolytic actual working environment, because temperature variation is big, plastics can expand with heat and contract with cold, cause the inner bag bubbling, cause electrolyzer to be scrapped; The 2nd, the steelframe aperture causes the local nothing of inner bladder outer wall to support greatly, is unable to undergo the collision of work package; The 3rd, be in the no support section in inner bag bottom in the hyperbaric environment for a long time, easier outside bubbling causes inner bag bottom cracking to be scrapped; The 4th, steelframe rotproofing difficulty, steelframe adopts Resins, epoxy to add the glass reinforced plastic parcel, if deal with improperly, the corrosion of the difficult anti-acid mist of steelframe, also there is the problem of work-ing life and maintenance in glass reinforced plastic simultaneously.

Summary of the invention:

In order to overcome the deficiency of existing cell technologies, the utility model provides a kind of quality height, good, the anti-collision of anticorrosion acid-proof performance, non-maintaining, the novel electrolytic bath of long service life.

The technical scheme in the invention for solving the technical problem is: be provided with a metal sheet on the steelframe bottom surface between overall plastic inner bag and the steelframe, four sides of steelframe are covered with the wire netting that welds with steelframe, the welding of the unit of plastic of some amount and inner bag is clipped in wire netting between unit of plastic and the inner bag outside wire netting; Add the plastic casing of a global formation in the outside of steelframe, shell is riveted on the steelframe with plastic rivet; Shell and inner bag interface welded seal, steelframe, metal sheet and wire netting are sealed among inner bag and the shell.

Beneficial effect: the one, because layer overlay metal sheet on the steelframe bottom surface, inner bag places on the plate, inner bag bottom weight capacity improves greatly; The 2nd, wire netting is spread in four sides of steelframe, and inner bag is fixed on wire netting and the steelframe by unit of plastic, more than 2 improvement, overall plastic inner bag each several part is all supported fully, eliminated inner bag under the situation of high temperature and high pressure, do not produced bubbling, the phenomenon that causes electrolyzer to break and damage because of the part wall of inner container has to support, the inner bag impact resistant capability is greatly improved, thereby has prolonged the work-ing life of electrolyzer; The 3rd, steelframe, metal sheet and wire netting are sealed between the inner bag and shell of two overall plastic global formations, avoided the invasion and attack of steelframe, metal sheet and wire netting because of acid mist, thoroughly solved the maintenance issues of steelframe.

Embodiment:

As Fig. 1, Fig. 2, shown in Figure 3, the steel plate 4 that the utility model upper berth, steelframe 2 bottom surface one deck between overall plastic inner bag 1 and steelframe 2 is thin, steel mesh 3 is spread in four sides of steelframe 2, and steel mesh 3 and steelframe 2 welded, outside steel mesh 3, weld the unit of plastic 5 of some amount, steel mesh 3 is clipped between unit of plastic 5 and the inner bag 1 with inner bag 1; Add the plastic casing 6 of a global formation in the outside of steelframe 2, shell 6 is riveted on the steelframe 2 with the plastic rivet of some amount; , with shell 6 and inner bag 1 interface 7 place's welded seals steelframe 2, steel plate 4 and steel mesh 3 are sealed among inner bag 1 and the shell 6 with plastic welding.
