The utility model discloses an inflatable sealing device for aluminum melt degassing equipment, which comprises a box body of the aluminum melt degassing equipment and an upper cover fastened on the box body. There is a groove, and an inflatable sealing ring is arranged in the groove, and a through hole is arranged on the lower side wall of the groove, and the gas nozzle of the inflatable sealing ring extends out of the through hole. When the inflatable sealing ring is filled with gas, it squeezes the upper The fastening edge of the cover and the groove on the box body are sealed to connect the box body and the upper cover. Because the inflatable sealing device of the utility model belongs to the flexible seal, it has good sealing performance, simple structure and low requirements on the operator's operation skills.
Description
Technical field
The utility model relates to the tightness system of metallurgical equipment, relates in particular to a kind of air inflation sealing device of aluminum melt degassing equipment.
Background technology
In molten aluminum liquid, liquid aluminium liquid inevitably contains gases such as hydrogen.What of gas directly have influence on the quality of follow-up aluminum products in the aluminium liquid, if contain more gas in the aluminium liquid, follow-up aluminum products will produce a lot of pores, reduce the mechanical property of aluminum products.
Aluminium liquid getter is the visual plant in the refining of aluminium liquid, and present aluminium liquid getter mainly contains vacuum aluminium liquid getter and rare gas element aluminium liquid getter.Described two kinds of aluminium liquid getters all need the casing of getter to keep higher sealing property.The tightness system of the aluminium liquid getter that generally adopts in the prior art is as shown in Figure 1: it comprise aluminium liquid getter casing 04, be fastened on the loam cake 01 on the casing 04, described loam cake 01 is provided with groove 02, is filled with the asbestos packing 02 of the casing 04 of sealing loam cake 01 and aluminium liquid getter in the groove 02.This sealed structure mainly relies on asbestos packing to seal, it depends primarily on the compactness of asbestos packing, and the compactness of asbestos packing depends primarily on preliminary tension when filling and the deadweight of loam cake, after using for some time, the sealing property of this device will reduce greatly, and the gas in the casing is revealed easily.The operator's of the sealing property of this tightness system and installation asbestos packing degree of being skilled in technique has much relations simultaneously, and general new hand is difficult to install asbestos packing, makes loam cake and casing realize sealing.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides the air inflation sealing device of the aluminum melt degassing equipment of a kind of simple in structure, easy handling and good seal performance.
For achieving the above object, the technical solution of the utility model is: a kind of air inflation sealing device of aluminum melt degassing equipment, comprise the casing of aluminum melt degassing equipment and be fastened on loam cake on this casing, the periphery outside on described casing top is provided with groove, be provided with the gas-flow closure circle in the groove, the lower wall of described groove is provided with through hole, the valve of gas-flow closure circle extends this through hole, during gas-flow closure circle aerification, the locking edge of its extruding loam cake and the groove on the casing, casing and loam cake are tightly connected.
Described casing top is provided with flanging, and loam cake is fastened on the flanging, and the outside of flanging is provided with groove, is provided with the gas-flow closure circle in the groove, and the lower wall of described groove is provided with through hole, and the valve of gas-flow closure circle extends this through hole.
The utility model adopts above structure, utilize the outer upper of casing to be provided with groove, be provided with the gas-flow closure circle in the groove, when inflating to the gas-flow closure circle, the airbag inflation of gas-flow closure circle, the locking edge of its flexible extruding loam cake and the groove on the casing, realize the sealing of loam cake and casing, in the time of need opening loam cake, can make the venting of gas-flow closure circle, the air bag of gas-flow closure circle shrinks, and is easy to opening of loam cake.Air inflation sealing device of the present utility model is because belong to flexible sealing, and its good seal performance is simple in structure, and is low to the operations of operators technical requirements.
