Abstract
The utility model discloses an insulation universal expansion joint used in smoke exhaust pipelines of electrolytic smoke treating engineering of aluminium electrolysis industry. The utility model has the structure that an upper insulation hemisphere and a lower insulation hemisphere both made of insulation materials are movably sheathed; the connecting position between the lower insulation hemisphere and the upper insulation hemisphere is sealed; the lower insulation hemisphere and the upper insulation hemisphere are connected through a fastener; the upper end of the upper insulation hemisphere is pressed with an opening steel plate whose middle has an opening; the opening steel plate is fixedly connected with a corrugated pipe. The utility model has the advantages and effect that the insulation universal expansion joint can obtain the effect completed by a plurality of devices and saves investment and occupied space. The utility model solves the problem that smoke exhaust pipelines can not be connected easily because of the replacement and the deformation of overhauling devices of electrolytic tanks. The utility model also solves the problem that local connecting positions between electrolytic plant buildings and smoke exhaust pipelines are damaged because of the deformation of the smoke exhaust pipelines caused by heat effect.
Description
Technical field
The utility model relates to that a kind of electrolysis flue gas that is applied in the electrolysis of aluminum industry is administered the engineering smoke discharging pipe and accumulates high-tension electrolyzer with high electric current and steel construction is subjected to insulation tube and the telescopic joint that smoke discharging pipe heat rises and produces the distortion occasion, relates in particular to the universal telescopic joint of a kind of insulation.
Background technology
The electrolyzer of aluminum smelting technology belongs to high electric current, accumulates high-tension aluminium metallurgy equipment, and the temperature of aluminum smelting technology is higher, has caused the electrolyzer steel construction piece that certain deformation is arranged.The smoke discharging pipe of electrolysis flue gas governing system and electrolyzer outlet pipe coupling, and be fixed on the potroom buildings.So must disposing, the smoke discharging pipe of electrolysis flue gas governing system has insulation and resistance to deformation equipment.Insulation tube that is provided with on the present smoke discharging pipe and telescopic joint are that two sections pipes are separately positioned on the smoke discharging pipe, and the anti-deformation of expansion pipe is relatively poor, has caused shortening the work-ing life of smoke discharging pipe; And when electrolytic cell overhaul, smoke discharging pipe connects difficulty, has reduced working efficiency.

The utility model is exactly that a kind of universal telescopic joint of insulation that but the insulating power any direction rotates, telescopicing performance is good that has is provided in order to solve the problems of the technologies described above.
In order to solve the problems of the technologies described above, the utility model is achieved in that the universal telescopic joint of insulation, its structure is as follows: by insulating material first spheroid of insulation of making and second spheroid pivot bush unit that insulate, insulate second spheroid and the insulation first spheroid junction airtight, insulate second spheroid with the insulation first spheroid be to be connected by fastening piece, the insulate upper end of first spheroid is pressed with the opening steel plate of intermediate openings, and the opening steel plate is fixedlyed connected with corrugated tube.
The upper end of described corrugated tube is provided with discharge flange.
The lower end of described second spheroid of insulation is provided with inlet flange.
Described fastening piece is to be made of following structure: be arranged on outside, second spheroid bottom of insulation and prolong the ring-type steel ring that it circumferentially is provided with, with the ring-type steel ring by bolted vertical rod, the other end of vertical rod is fixedlyed connected with the opening steel plate.
Advantage of the present utility model and effect are as follows:
1, can solve the effect that several equipment are finished, the space of saving investment and occupying by a universal telescopic joint of insulation.
2, solved the displacement of electrolytic cell overhaul equipment and be connected difficult problem with the smoke discharging pipe that distortion causes.
3, solved the problem that causes the local damage that smoke discharging pipe distortion and potroom buildings connection produce because of heat effect.
Below in conjunction with the drawings and specific embodiments the utility model is done and to be described in further detail.
