Description
Technical field
The utility model relates to a kind of continous way does not have not meshbeltfurnace sealed device for drive-shaft of horse, is applicable to the not sealing device of meshbeltfurnace of no horse.Belong to not meshbeltfurnace technical field of no horse.
Background technology
At present, grill-hearth travelling oven is the common equipment of heat treatment industry, and the grill-hearth travelling oven of prior art has been generally not structure of horse, and this have a not meshbeltfurnace of structure of horse, have the advantages that to be convenient to keep furnace atmosphere, but have the shortcoming of complicated integral structure, cost height, maintenance difficult.Therefore, the someone begins to use continous way and does not have not meshbeltfurnace of horse now.Owing to do not have horse sealing not, therefore, cause furnace atmosphere to leak easily, power transmission shaft in the meshbeltfurnace reaches outside the furnace chamber in furnace chamber, be easy to generate the slit between power transmission shaft and the furnace wall, the atmosphere in the meshbeltfurnace is leaked, and majority is that the junction between power transmission shaft and the furnace wall produces.Because be provided with a lot of power transmission shafts in the meshbeltfurnace, therefore, the sealing problem of resolving between power transmission shaft and the furnace wall is most important.There is the continous way of technology not have not meshbeltfurnace of horse,, therefore is easy to generate furnace atmosphere and leaks, thereby bring adverse influence to heat treatment production owing to do not solve the sealing problem of power transmission shaft preferably.
The utility model content
The purpose of this utility model is not have the not sealing problem of meshbeltfurnace power transmission shaft of horse for the continous way that solves prior art, provides a kind of continous way simple in structure, with low cost not have not meshbeltfurnace sealed device for drive-shaft of horse.
The purpose of this utility model can reach by taking following measure:
Continous way does not have not meshbeltfurnace sealed device for drive-shaft of horse, and its design feature is: be made of heat insulation/trapping cover, seal washer radiator, high temperature resistant bearing and heat-resisting rotating seal ring; Heat insulation/trapping cover is positioned at furnace lining and power transmission shaft joint, inner chamber socket power transmission shaft, outer wall and the tight cramp joint of furnace lining of heat insulation/trapping cover, constitute first resealing: the two ends of power transmission shaft extend outward outside the body of heater, the formation outer end, radiator and the socket of described outer end, one end of radiator and heat insulation/trapping be locked connect airtight touch, the internal chamber wall of the other end joins by high temperature resistant bearing and heat-resisting rotating seal ring and aforementioned outer end, seal washer is positioned at the junction of radiator and heat insulation/trapping cover and is close to the outer wall of furnace lining.
The purpose of this utility model can also reach by taking following measure:
Described heat insulation/the trapping cover can be hollow umbrella shape, the shape of its inner chamber and power transmission shaft outer shape are coincide, its head is umbrella shape, the tight cramp joint of the part of head and furnace lining, another part exposes and with the tight cramp joint of radiator, seal washer be positioned at power transmission shaft umbrella shape head and radiator the junction and with power transmission shaft umbrella shape head, furnace lining outer wall and the tight cramp joint of radiator.
Described radiator body can be the easy mounted-dismounted type structure, is fixed on the end of power transmission shaft by some people's lead screw, nut.
Described seal washer can be the refractory seals gas ket.
The utlity model has following outstanding beneficial effect:
1, the utility model is owing to adopt heat insulation/trapping cover sealing and radiator, furnace lining, the hot two-stage of temperature resistant encapsulation to seal to power transmission shaft, therefore can prevent that the outer atmosphere of furnace atmosphere and stove from exchanging by power transmission shaft, thereby the heat that reduces power transmission shaft scatters and disappears, improve the malleation of furnace atmosphere, help energy savings, guarantee the quality of heat treated article.
2, the utility model is simple in structure, and material therefor is few, and is with low cost, is applicable to that not having horse in the borderland formula not promotes the use of in the meshbeltfurnace.
Description of drawings
Fig. 1 is that the structure of an embodiment of the utility model is cutd open figure.
The specific embodiment
Specific embodiment:
With reference to Fig. 1, present embodiment is made of heat insulation/trapping cover 1, seal washer 2, radiator 3, high temperature resistant bearing 4 and heat-resisting rotating seal ring 5; Heat insulation/trapping cover 1 is positioned at furnace lining 6 and power transmission shaft 7 joints, and inner chamber socket power transmission shaft 7, outer wall and the furnace lining 6 tight cramp joints of heat insulation/trapping cover 1 constitute first resealing; The two ends of power transmission shaft 7 extend outward outside the body of heater, formation outer end 8, radiator 3 and 8 sockets of described outer end, an end of radiator 3 with heat insulation/trapping cover 1 closely contacts, the internal chamber wall of the other end joins by high temperature resistant bearing 4 and heat-resisting rotating seal ring 5 and aforementioned outer end 8.
In the present embodiment:
Described heat insulation/trapping cover 1 is hollow umbrella shape, the shape of its inner chamber and power transmission shaft 7 outer shape are coincide, its head is umbrella shape, the part of head and furnace lining 6 tight cramp joints, another part exposes and with radiator 3 tight cramp joints, seal washer 2 be positioned at power transmission shaft 7 umbrella shape heads and radiator 3 the junction and with power transmission shaft 7 umbrella shape heads, furnace lining outer wall and radiator 3 tight cramp joints.Radiator 3 main bodys are the easy mounted-dismounted type structure, are fixed on the end of power transmission shaft by some people's lead screw, nut.The outside of furnace lining also is provided with furnace shell 11, makes the better heat preservation in the stove.
In the present embodiment, power transmission shaft 7 with moulding is installed in the meshbeltfurnace earlier, expose outside the body of heater two ends 8 of power transmission shaft 7, exist gap between power transmission shaft 7 and the furnace lining 6 this moment, heat insulation/trapping cover 1 is compressed into gap between power transmission shaft 7 and the furnace lining 6 from the outer end 8 of power transmission shaft, and make the outer wall of heat insulation/trapping cover 1 and first resealing of furnace lining 6 tight cramp joints, formation power transmission shaft, because the outer shape of power transmission shaft 7 and heat insulation/trapping are overlapped 1 inner chamber and are coincide, therefore heat insulation/trapping cover 1 had both played the effect of first resealing, had not influenced the rotation of power transmission shaft again.For sealing and the radiating effect that increases power transmission shaft 7,8 places, outer end at power transmission shaft 7 are provided with radiator 3, the tight cramp joint in end of one end of this radiator 3 and heat insulation/trapping cover 1, in cramp joint place temperature resistant encapsulation packing ring 2 is set, the inner chamber of the other end is provided with high temperature resistant bearing 4 and heat-resisting rotating seal ring 5, described high temperature resistant bearing 4 closely contacts, can seal with the outer end 8 of power transmission shaft with heat-resisting rotating seal ring 5, constitutes second resealing of power transmission shaft 7.
Continous way does not have horse meshbeltfurnace when work not, and external drive mechanism drives sprocket wheel 9 rotations, and sprocket wheel 9 drives power transmission shafts 7 and rotates, thereby workpiece is passed through in burner hearth 10, and the temperature in the burner hearth 10 is at least up to 920 ℃.Owing to be provided with two resealings, therefore, can keep the temperature constant in the burner hearth 10, guarantee the thermal treatment quality of workpiece.
