Abstract
The utility model discloses a continuous high-temperature furnace. A thermal resistor serves as a heating element, a heat-insulating cavity is arranged between the heating element and a furnace tube, and the heating element is arranged in the heat-insulating cavity and is not directly contacted with the furnace tube; and the furnace tube, a furnace head and a furnace tail form a relative sealing entity, process gas and other gases can flow in and out of a vessel at positive pressure to prevent the air from entering the furnace tube; in addition, a sealing ring is arranged between the furnace tube and the furnace cavity to prevent the gas in the furnace tube from entering a furnace shell cavity, and inert gas is led to the furnace shell cavity to protect the outer wall of the furnace tube, the heating element and the heat-insulating material. The furnace tube does not serve as the heating element, so that the resistance valve of the furnace tube is not limited, and the wall of the furnace tube can be thickened basically without being corroded, so that the service life is obviously prolonged, and the furnace tube can be used generally above eight months; and the furnace tube can be installed individually and is convenient to assemble and disassemble, therefore, the maintenance workload is greatly simplified.
Description
Technical field
The utility model relates to high temperature furnace, is specially a kind of continuous high temperature stove that can be used for the continuous roasting of material.
Background technology
As heater, boiler tube is direct fill insulant material outward boiler tube for the continuous high temperature stove of Shi Yonging now.Because high temperature, graphite material easily and gases such as oxygen, hydrogen easily react and cause corrosion and damage, make body of heater have only about 20 days common service time.
Boiler tube need be close together with insulation material owing to will make heater, so, in case need repairing, needing to remove earlier insulation material, maintenance is extremely inconvenient, and this body of heater frequency of maintenance is again than higher, thereby brings the deuce to pay to the user.
The utility model content
The technical problem that the utility model solved is to provide a kind of continuous high temperature stove, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of continuous high temperature stove utilizes thermal resistance as heater element, and an incubation cavity is set between heater element and boiler tube, and heater element is arranged in incubation cavity, does not directly contact with boiler tube; Simultaneously, be respectively arranged with the import and the outlet of protective gas in the furnace shell upper and lower, utilize protective gas that furnace part is protected.
The utility model needs with boat material to be advanced from the burner end in use; after roasting finishes; from the discharging of stove tail end; boiler tube, burner, integral body that seals relatively of stove urogenesis; atmosphere such as process gas can keep malleation into and out of boat the time; prevention air etc. enters boiler tube; be provided with sealing ring again as sealing device between boiler tube and the furnace chamber simultaneously; the interior atmosphere of boiler tube can not be entered in the furnace shell chamber; and furnace shell has fed inert protective gas in the chamber; can protect furnace tube outer wall again, heater and insulation material.
The utility model is not subjected to the resistance value requirement owing to boiler tube does not remake heater, thereby furnace wall can strengthen thickness.
Beneficial effect:The utility model is owing to thicken boiler tube, and outer wall does not have corrosion substantially, significant prolongation service life, generally can use more than eight months.And because boiler tube is installed separately, easy accessibility has been simplified the workload of keeping in repair widely.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of continuous high temperature stove referring to Fig. 1, comprise burner 2, body of heater and stove tail 7, wherein the opening in the middle of the burner 2 is a process gas inlets 1, opening in the middle of the stove tail 7 then is process gas outlet 6, in addition, at the intersection of stove tail 7 and body of heater, also be provided with sealing device 5, in the present embodiment, sealing device 5 comprises two sealing rings that respectively have up and down.
In the oven body part of present embodiment, be the heat insulation protecting material in the furnace shell 8, be provided with boiler tube 9 in the furnace shell 8, boiler tube 9 usefulness incubation cavities 11 carry out insulation blocking, are provided with heating unit assembly 3 in the incubation cavity 11, and heating unit assembly 3 does not directly contact with boiler tube 9.
In the bottom of furnace shell 8, also be provided with protective gas import 10 simultaneously, the top of Dui Ying furnace shell 8 is provided with protective gas outlet 4 with it.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
