Description
Technical field
The utility model belongs to Equipment for Heating Processing field, and specifically, what relate to is a kind of furnace door sealing device being mainly used in the elevated-temperature seal batch-type furnace that the occasion such as industrial production or laboratory uses.
Background technology
In industrial production, school or scientific research institutions, mostly need a kind of elevated-temperature seal batch-type furnace.The batch-type furnace of prior art manufacture has been difficult to good sealing effectiveness.The fire door of batch-type furnace is access way that is reinforced and production operation, and be provided with a circle rubber laminating encapsulant at the fire door edge pressing close to fire door one side, its Main Function fits with fire door to realize sealing.Rubber laminating encapsulant is due to the frequent unlatching of fire door, and mechanical wear is serious, and when in-furnace temperature is higher, easily agingly causes seal failure, and have a strong impact on furnace atmosphere, therefore effect is unsatisfactory.
Utility model content
Utility model object: the purpose of this utility model is to solve deficiency of the prior art, provides that a kind of structure is simple, good airproof performance, the batch-type furnace door seal device that durable in use, security is good.
Technical scheme: a kind of batch-type furnace furnace door sealing device described in the utility model, comprise the double-deck body of heater be made up of outer body of heater and internal layer body of heater, the double-deck fire door be made up of outer fire door and internal layer fire door, described outer body of heater outside is provided with outer fire door, described outer fire door outward flange is provided with sealing strip, some U-shaped breach are evenly provided with outside described outer fire door, described outer body of heater is connected with fastening screw, outer fire door and outer body of heater are compressed by fastening screw and sealing strip, described outer fire door is flexibly connected by connecting rod with outer body of heater, described internal layer body of heater is provided with interior fire door, groove is provided with outside described interior fire door, described groove is built with encapsulant, described outer fire door is connected by some springs with between internal layer fire door.
As optimization, described fastening screw and described U-shaped breach suitable.
As optimization, described U-shaped breach is arranged on the described upper and lower both sides of outer fire door.
As optimization, outside described interior fire door, the opening part width of groove is identical with the width of encapsulant.
As optimization, described encapsulant adopts high-temperature resistant rubber, can be specifically high temperature resistant silica gel or high temperature glass-fiber-fabric etc.
Beneficial effect: the utility model structure is simple, good airproof performance, double-deck design possess good mechanical performance under the high temperature conditions, prevents from use causing distortion, improves the security of sealing effectiveness and equipment in stove.
