Description
Technical field
The utility model relates to the Muffle pot expansion technique field of equipment for Heating Processing, especially the utilization to expansion joint technology, prevents volatilization and the waste of oil product in crude oil envelope after heating, the using appts that equipment for Heating Processing Muffle pot is expanded is more simple and reliable, both reduced cost, improved the life-span again; Relate in particular to the Muffle pot expansion joint structure in a kind of nitriding furnace.
Background technology
At present domestic larger manufacturing concern generally adopts the technology in Muffle pot free expansion in oil sealing, and this heating technique is due to oil volatile contaminate environment and waste resource in heat-processed, and need in oil groove, place scatterer.So not only destroy air ambient, and increased the running cost of producing.
Summary of the invention
Technical problem to be solved in the utility model is, solved existing Muffle pot and in oil sealing, heats the problem that makes oil produce volatilization contaminate environment and waste resource for existing.
The purpose of this utility model is that the utility model has solved existing Muffle pot and in oil sealing, heated the problem that makes oil produce volatilization contaminate environment and waste resource, has reduced fabrication and installation difficulty, provides cost savings, and has improved efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A Muffle pot expansion joint structure in nitriding furnace, comprises nitriding furnace body of heater, Muffle pot, nitriding furnace base of furnace body and table; Also comprise expansion joint, the first sealing-ring and the second sealing-ring; Described nitriding furnace body of heater is arranged on nitriding furnace base of furnace body, and Muffle pot is arranged in nitriding furnace body of heater, and table is fixed on nitriding furnace base of furnace body and is positioned at Muffle pot; Described the first sealing-ring is arranged between nitriding furnace body of heater and Muffle pot, for sealing the space between nitriding furnace body of heater and Muffle pot; Described the second sealing-ring is put between Muffle pot and table, for sealing the space between Muffle pot and table; Described expansion joint is arranged on the lower exit of Muffle pot, and the upper end of expansion joint is connected with the lower end of Muffle pot, and the lower end of expansion joint is connected with nitriding furnace base of furnace body.
When the utility model arrangement works, when Muffle pot heating, Muffle pot can be shifted the stretching force of expanded by heating on expansion joint onto, makes expansion joint produce Free Compression.The utility model adopts expansion joint to replace oil sealing sealing of the prior art, and then solve Muffle pot and in oil sealing, heated the problem that makes oil produce volatilization contaminate environment and waste resource, save again material, reduce fabrication and installation operation, reduced cost of investment, key is to have strengthened the stable mechanical property of equipment.
The first sealing-ring described in the utility model is cellucotton.The second sealing-ring described in the utility model is resistant to elevated temperatures sealing-ring.
Nitriding furnace body of heater described in the utility model is the nitriding furnace body of heater being applied in prior art in thermal treatment process, and Muffle pot described in the utility model is the Muffle pot in the nitriding furnace body of heater being applied in prior art in thermal treatment process; Be existing structure for its independent structure, the utility model is not described in detail.
The utility model advantage compared with prior art: the utility model, by improving, can overcome above shortcoming.The utilization of existing muffle furnace tank expansion technique, changed oil product volatilization in the past, reduced volatile oil and enter the problem of burner hearth difficult sealing, both provided cost savings, and improved again efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1, nitriding furnace body of heater; 2, Muffle pot; 3, expansion joint; 4, the first sealing-ring; 5, the second sealing-ring; 6, nitriding furnace base of furnace body; 7, table.
Embodiment
For content of the present utility model is become apparent more, be further described below in conjunction with accompanying drawing 1 and embodiment.
