Abstract
The invention discloses a sealing cover board and especially relates to a heat- and electric-insulation arc-shaped sealing cover board used for an aluminum electrolysis cell. The heat- and electric-insulation arc-shaped sealing cover board used for an aluminum electrolysis cell includes a frame board being arc-shaped, wherein a connecting aluminum plate is disposed on each of the two ends of the arc-shaped frame board. The outer end of each connecting aluminum plate is wrapped by two U-shaped electric-insulation boards. Each U-shaped electric-insulation board is wrapped by a U-shaped heat-insulation aluminum board. Each connecting aluminum plate is provided with a mounting hole. Each U-shaped electric-insulation board and each U-shaped heat-insulation aluminum board are respectively provided with bolt holes. A set of electric-insulation fastener is disposed at each bolt hole. The connecting aluminum plate, the U-shaped electric-insulation board and the U-shaped heat-insulation aluminum board are connected together through the electric-insulation fastener. The sealing cover board avoids high temperature grilling and can prevent the electric-insulation board from damage due to electrolyte and high temperature, so that the electrolysis cell can be normally used even in a high-temperature environment and the service life of a sealing cover is prolonged. The sealing cover board is electric-insulated and is not liable to damage and deform during a use process.
Description
Technical field
The present invention relates to
oneplant sealing cover plate, particularly relate to a kind of aluminum electrolyzing cell used partiting thermal insulation arc sealing cover plate.
Background technology
China is increasingly strict to the requirement of environment protection, for aluminum electrolysis industry, can produce harmful hydrogen fluoride gas and flue dust when aluminium cell is produced, and therefore just needs to adopt sealing cover plate to be sealed by aluminium cell, avoids obnoxious flavour and flue dust to leak.Airtight electrolyzer is also more conducive to the Effec-tive Function of Smoke Gas Purity by Electrolysis system.
Traditional electrolyzer cover plate adopts rectangle aluminum pipe to be welded into basic framework, then welds the sealing of one deck aluminium sheet thereon, and welding capacity is comparatively large, manufactures loaded down with trivial details, yielding after welding.
In the normal production process of electrolyzer, need constantly to change anode, frequent opening encapsulation cover plate, when changing anode, the ionogen of a part of high-temperature fusion can be splash.When partial electrolyte splashes on the insulating shield of conventional seals cover plate, high temperature makes insulating material carbonization, causes failure of insulation, causes on-the-spot sealing cover plate insulation turnover rate higher, also causes danger of hazardous electrical discharges, cause great danger to personnel safety.
Anode distance when traditional straight shape sealing cover plate is installed and after installing is also comparatively near, and when electrolyzer is produced, anode self-temperature is also higher, and cover plate is subject to high temperature for a long time and scorches, and is out of shape comparatively serious, causes larger difficulty to the maintenance of follow-up cover plate.
Summary of the invention
The present invention is exactly to solve the problems of the technologies described above; and the one provided aluminum electrolyzing cell used partiting thermal insulation arc sealing cover plate; it avoid cover plate to scorch by high temperature; protection insulcrete avoids ionogen and high temperature; electrolyzer still can normally be used in high temperature environments; extend the work-ing life of sealing cover plate, it in use insulate not fragile, not yielding.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A kind of aluminum electrolyzing cell used partiting thermal insulation arc sealing cover plate, its structure is as follows: frame board is arc frame board, the both ends of arc frame board are respectively provided with one piece and connect aluminium sheet, the outer end that every block connects aluminium sheet is coated with two pieces of U-shaped insulcretes, the U-shaped insulcrete of every block is coated with one block of U-shaped heat insulation aluminium sheet, connect on aluminium sheet and offer open holes, the U-shaped insulcrete of every block and U-shaped heat insulation aluminium sheet offer bolt hole, each bolt hole place is provided with a set of insulated fasteners, connection aluminium sheet, U-shaped insulcrete and U-shaped insulcrete is linked together by insulated fasteners.
The cross section of above-mentioned arc frame board is corrugated.
Above-mentioned arc frame board is die mould corrugated aluminium sheet.
The outside surface of above-mentioned arc frame board is provided with thermal insulating coating.
Above-mentioned arc frame board is provided with one-level mark time and secondary mark time.
Above-mentioned one-level is marked time and secondary is marked time is welded on arc frame board.
Above-mentioned secondary is marked time and is provided with handle.
Above-mentioned secondary is marked time and is arranged on the middle part of arc frame board, and one-level is marked time and is arranged on the bottom of arc frame board.
Two blocks of above-mentioned connection aluminium sheets and arc frame board are by being welded to connect.
The above-mentioned structure of often overlapping insulated fasteners is as follows: containing a bolt, a spring washer, a packing ring, a nut, two insulation spacers, an insulation thimble and insulating washers; Insulating washer is arranged in the hole of connection aluminium sheet, and be arranged on U-shaped heat insulation aluminium sheet by U-shaped insulcrete and be connected on aluminium sheet, insulation thimble is inserted in bolt hole, successively installing insulating pad, bolt, another sheet insulation spacer, packing ring, spring washer and nut.
Owing to adopting technique scheme, tool of the present invention is had the following advantages and effect:
Arc frame board adopts die mould corrugated aluminium sheet, for thermal insulation protection cover plate not by the impact that high temperature scorches.Aluminium sheet after die mould adopts rational ripple type, both ensures physical strength, decreases welding job amount to greatest extent again.The reinforced seal aluminium sheet of arc increases the distance between anode, avoids high temperature to scorch.Portion and top adopt heat insulation aluminium sheet to protect insulcrete; because the fusing point of aluminium sheet is higher, can prevent when art electrolysis cells operates, the direct scaling loss of the high-temperature electrolysis confrontation insulcrete spilt; electrolyzer still normally can be used in high temperature environments, extend the work-ing life of sealing cover plate insulation.Workman also can climb up upper part of the electrolytic cell by two-stage stepping easily.It in use insulate not fragile, not yielding.
