Abstract
The utility model discloses a silicon nitride heating device. A cover plate and a press plate are arranged in positions on a silicon nitride heating body with a distance from a heating part, a sealing ring is arranged on the silicon nitride heating body arranged between the cover plate and the press plate, the cover plate and the press plate are connected, a position limiting bulge is arranged on the silicon nitride heating body, the inner side of the sealing ring is provided with a groove, the sealing ring covers the position limiting bulge, the side surface of the press plate is provided with a clamp plate, and the clamp plate covers the sealing ring. The silicon nitride heating device can prevent the sealing ring from generating displacement on silicon nitride.
Description
Technical field
The utility model relates to a kind of electro-heat equipment, is specifically related to a kind of silicon nitride electro-heat equipment.
Background technology
General electric heater unit is to adopt the resistance wire heating, isolate with insulating material, also useful PTC pottery quartz ampoule, all exist useful life short, it mainly is poor stability, cause electric leakage easily, Chinese patent: silicon nitride heat generating body and manufacture method thereof provide a kind of silicon nitride heat generating body, solved with the life-span weak point, the subject matter of poor stability, but when silicon nitride carries out heat exchange as heater, because silicon nitride heat generating body surface smoothing, have heat to produce, certain pressure is arranged when carrying out heat exchange, the sealing when silicon nitride heat generating body carries out heat exchange in container is not easy to realize.
At the problems referred to above, someone has proposed a kind of silicon nitride electro-heat equipment, it utilizes sealing ring to be contained on the silicon nitride heat generating body, though sealing problem has obtained solution,, add the silicon nitride heat generating body surface smoothing because sealing ring does not obtain any position-limiting action, there is heat to produce during work, certain pressure is arranged when carrying out heat exchange, under pressure, cause the relative silicon nitride heat generating body of sealing ring to produce displacement.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model provides a kind of silicon nitride electro-heat equipment, and the utility model can prevent that sealing ring is subjected to displacement on silicon nitride.
The technical scheme that realizes above-mentioned purpose is as follows:
The silicon nitride electro-heat equipment, on silicon nitride heat generating body, one cover plate and pressing plate are set apart from heating place, on the silicon nitride heat generating body between cover plate and the pressing plate, sealing ring is set, cover plate is connected with pressing plate, described silicon nitride heat generating body is provided with spacing preiection, and the sealing ring inboard is provided with groove, and sealing ring is coated on the spacing preiection, the side of pressing plate is provided with clamping plate, and these clamping plate coat described sealing ring.
The side of described cover plate and pressing plate is equipped with recess, and the left end of described sealing ring and right-hand member are arranged in described recess.
Be arranged at intervals with radiating groove on the described clamping plate.
Described spacing preiection is annular spacing preiection.
Adopted such scheme, described silicon nitride heat generating body is provided with spacing preiection, and the sealing ring inboard is provided with groove, sealing ring is coated on the spacing preiection, by spacing preiection, can limit sealing ring and move, like this, sealing ring just can't displacement on pressing plate, guarantees the operate as normal of silicon nitride heat generating body.The side of pressing plate is provided with clamping plate, and these clamping plate coat described sealing ring.After by clamping plate sealing ring being coated, the position of further having guaranteed sealing ring, and sealing ring can stop its deformation by clamping plate when deformation takes place, guarantee the sealing function of sealing ring.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
In the accompanying drawing, 1 is a silicon nitride heat generating body, and 2 is cover plate, and 3 is pressing plate, and 4 is sealing ring, and 5 is spacing preiection, and 6 is clamping plate, and 7 is radiating groove.
Embodiment
With reference to Fig. 1, be silicon nitride electro-heat equipment of the present utility model.On silicon nitride heat generating body 1, one cover plate 2 and pressing plate 3 are set apart from heating place certain distance.Sealing ring 4 is set on the silicon nitride heat generating body between cover plate and the pressing plate, and sealing ring is resistant to elevated temperatures sealing ring.Cover plate 2 is fixedlyed connected by screw or rivet with pressing plate 3, and the side of cover plate and pressing plate is equipped with recess.Silicon nitride heat generating body 1 is provided with spacing preiection 5, and spacing preiection 5 is annular spacing preiection.Sealing ring 4 inboards are provided with groove, and sealing ring is coated on the spacing preiection, and the left end of sealing ring and right-hand member are arranged in described recess.The side of pressing plate is provided with clamping plate 6, and these clamping plate 6 coat described sealing ring, are arranged at intervals with radiating groove 7 on the clamping plate, and the heat that radiating groove can be accelerated on the sealing ring distributes, and avoids sealing ring too fast aging.
