Abstract
The utility model relates to a belt-shaped furnace, which belongs to an industrial furnace. The technical problems to be solved include the shrinkage cracking of ceramic fiber boards under high temperature, the sinking of the setter plate, the collapse of the furnace chamber, the drop of debris and the like. The technical point of the belt-shaped furnace is that: refractory mounting boards are mounted on the walls and top of a furnace chamber, fiber felt insulating layers are fixed on the inner walls of the refractory mounting boards by rivets, a refractory layer which is formed by assembled modules is stuck on the inner walls of the fiber felt insulating layers, a setter platform is mounted on the upper part of a scissor type hydraulic lift platform, and comprises a loading platform and a setter plate, the loading platform comprises a ceramic fiber product and a plurality of corundum mullite tubes, and the furnace chamber is sealed by the stepped convex-concave seal between hard ceramic fiber boards and flexible ceramic modules. The structure of the belt-shaped furnace is firm and stable, and has the advantages of high temperature control precision, low energy consumption, clean furnace chamber and uniform temperature, and moreover, the belt-shaped furnace can be conveniently and effectively operated, and can stably operate for a long time.
Description
Technical field
The utility model belongs to industrial furnace, specifically is a kind of resistance furnace that is used for electronic ceramics (function ceramics and structural ceramics), magnetic material and powder metallurgy high temperature sintering.
Background technology
Bell jar stove serial equipment mainly is applicable to the high-sintering process of electronic ceramics (function ceramics and structural ceramics), magnetic material and powder metallurgy.Can be divided into bottom elevation and two kinds of top liftings from loading and unloading material mode, can divide circular and square two kinds from furnace binding.The traditional bell jar stove that uses takes ceramic beaverboard to assemble on chamber structure at present, its shortcoming is ceramic beaverboard shrinkage cracking, the load bearing board sinking of can sinking at high temperature easily, simultaneously because the proportion of ceramic beaverboard is bigger, the bell jar stove furnace roof of making so just caves in easily, whole burner hearth falls slag easily in sintering process, has a strong impact on the cleanliness factor of fire box temperature uniformity and burner hearth and material on sintering process.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned existing in prior technology weak point, provide do not collapse top, load bearing board of a kind of chamber structure firm stable to sink, has the temperature-controlled precision height, energy consumption is low, and temperature is even, hearth sealability good, cleanliness factor is high, be difficult for falling the bell jar stove of advantages such as slag.
Technical solution adopted in the utility model is: a kind of bell jar stove, mainly containing furnace body frame, burner hearth and scissors hydraulic elevator platform forms, furnace body frame is a up-down structure, top is burner hearth fixedly, the bottom is the scissors hydraulic elevator platform fixedly, around the burner hearth and top is equipped with the installing plate of anti-the material, and the installing plate of anti-material inwall has the fibrofelt heat-insulation layer with the rivet rivet clasp, and it is the flame retardant coating that module is spliced to form that the gluing of fibrofelt heat-insulation layer inwall has structure.Several are inserted along the U-shaped heating element heater Si-Mo rod that square burner hearth distributes all around in the burner hearth top, have exhaust outlet at roof of the furnace, and thermocouple inserts burner hearth from the top, and the both sides of scissors hydraulic elevator platform are hinged with the driving oil cylinder respectively, are covered with load bearing board on the loading platform.The position of travel switch restriction scissors hydraulic elevator platform lifting, scissors hydraulic elevator platform top is equipped with holds the burning platform, holds the burning platform and comprises loading platform and load bearing board, and loading platform is made up of ceramic fibre and many group corundum-mullite pipes.The step convex-concave sealing between hard ceramics fiberboard and the soft ceramic module is adopted in the burner hearth sealing.
The beneficial effects of the utility model are: the corundum-mullite pipe is mainly used in better load-bearing, prevent that load bearing board from sinking in sintering process, burner hearth and hold to burn and adopt the anti-material and the step convex-concave of anti-material to seal between the platform, effectively reduce the heat transmission, reduced fire door temperature all around, solved the phenomenon that steel plate comes off because of the high-temperature oxydation surface; Burner hearth adopts unique concavo-convex assembly unit of step, smooth, the sealing of cavity have effectively been guaranteed, hold and burn many corundum-mullite pipes of platform increase, more efficiently load-bearing, prevent that the overweight load bearing board that causes of material from sinking, whole burner hearth all adopts fibrous material of the same race, and the uniformity of temperature field is guaranteed, and simultaneously the temperature homogeneity of burner hearth is significantly improved; Load bearing board adopts the corundum-mullite material, and the thermal conductivity that it is good, wearability, corrosion resistance, high strength have guaranteed that load bearing board is indeformable in long-term the use, do not rupture, the life-span is long.
Description of drawings
Fig. 1 is the front view of a kind of bell jar stove of the utility model.
