Abstract
The utility model discloses a self-sealing device of a trolley type heat treatment furnace, which comprises the following components: sealing grooves which are provided at two sides of the trolley, and sealing plates which are provided at two sides of the furnace body. Sand is filled in the sealing grooves. The sealing plates are placed in the sand. The furnace body above the sealing plates is fixedly provided with a fireproof fiber boss. Two side edges of the trolley are provided with heatproof cast iron rings which closely contact with the fireproof fiber boss. The self-sealing device of the trolley type heat treatment furnace has the following advantages: ensuring close and reliable sealing, preventing underflow of the heat in the furnace, and improving heat efficiency of the heat treatment furnace.
Description
Technical field
The utility model relates to a kind of sealing device, particularly a kind of self-seal device that is used for Type Car-bottom Heat Treating Furnace.
Background technology
The conventional sealing device of Type Car-bottom Heat Treating Furnace is the sand seal device, shown in accompanying drawing 1, comprises and the seal groove 1 of being located at chassis 7 both sides and the sealing plate 2 of being located at body of heater 8 both sides in the seal groove 1 sand is housed, and puts under in the sand through sealing plate 2 to seal.In order to prevent the heat underflow heated sealant plate 2 and seal groove 1 in the stove, make its temperature distortion, cause poorly sealed; Precompressed has refractory fibre platform 3 above sealing plate 2, and build by laying bricks or stones with refractory brick 4 at the edge of chassis 7, has hindered the underflow of a part of heat; But because chassis moves, between chassis edge and refractory fibre platform, still exist the running clearance of 50-80mm, the heat in the stove will be along this running clearance underflow; Not only direct losses a part of heat; And this heat also makes sealing plate and seal groove temperature distortion, and is poorly sealed, influenced the thermal efficiency of Type Car-bottom Heat Treating Furnace.Build the refractory brick at the chassis edge in addition by laying bricks or stones, essence takes place when coming out of the stove " water-cooled " split expansion, the refractory brick 4 that expands when advancing stove once more can be drawn and decrease refractory fibre, has reduced sealing effectiveness.
The utility model content
To above-mentioned deficiency, the utility model provides a kind of self-seal device that is used for Type Car-bottom Heat Treating Furnace, and the sealing of sealing device is tight, reliable, has stoped the underflow of furnace heat, has improved the thermal efficiency of heat-treatment furnace.
The utility model is to realize through such technical scheme: a kind of self-seal device of Type Car-bottom Heat Treating Furnace; Comprise the seal groove of being located at the chassis both sides and the sealing plate of being located at the body of heater both sides; Sand is housed in the seal groove, and sealing plate places in the sand, it is characterized in that: on the body of heater above the sealing plate, be installed with the refractory fibre boss; The both sides of the edge of chassis are equipped with the heat-resisting cast iron ring, and the heat-resisting cast iron ring closely contacts with the refractory fibre boss.
Owing to adopted said structure, the beneficial effect of the utility model is following: the refractory fibre boss in the utility model is compared with the refractory fibre platform of prior art, many precompressed 40% refractory fibre; Make it to produce a seal boss; The heat-resisting cast iron at chassis edge is closely contacted with the refractory fibre boss, do not had the gap, because the characteristics of refractory fibre compression rebound; Formed sealing fully; Can underflow on the chassis face with the heat in stove retaining, thereby can not make sealing plate and seal groove temperature distortion, prolonged the sealing effectiveness of sealing plate and seal groove.Heat-resisting cast iron is compared with refractory brick, and heat-resisting cast iron has the long performance of better anti-oxidant antibiosis, when being heated cooling; The swell increment of volume is littler; And meeting water-cooled can not be difficult for scratching refractory fibre, the service life of having improved sealing device as brick " not cracked " but the time.

The specific embodiment
For purpose, technical scheme and the beneficial effect that is expressly understood the utility model more, below in conjunction with accompanying drawing the utility model is done further explanation, but the protection domain of the utility model is not limited in following examples.
With reference to Fig. 2, the self-seal device of a kind of Type Car-bottom Heat Treating Furnace of the utility model comprises the seal groove 1 of being located at chassis 7 both sides and the sealing plate 2 of being located at body of heater 8 both sides; On the body of heater above the sealing plate 28 precompressed refractory fibre boss 5; The both sides of the edge of chassis 7 are equipped with heat-resisting cast iron ring 6, and heat-resisting cast iron ring 6 closely contacts with refractory fibre boss 5, form sealing fully; Heat in the stove is kept off on the chassis face; In the seal groove 1 sand is housed simultaneously, sealing plate 2 puts under and carries out the sealing of second road in the sand, has stoped the excessive of heat fully.
Refractory fibre boss 5 in the utility model is compared with the refractory fibre platform 3 of prior art; Many precompressed 40% refractory fibre, eliminated the gap between chassis edge and body of heater, because the characteristics of refractory fibre compression rebound; Formed sealing fully; Can underflow on the chassis face with the heat in stove retaining, thereby can not make sealing plate 2 and seal groove 1 temperature distortion, prolonged the sealing effectiveness of sealing plate and seal groove.Heat-resisting cast iron is compared with refractory brick, and heat-resisting cast iron has the long performance of better anti-oxidant antibiosis, when being heated cooling; The swell increment of volume is littler; Heat-resisting cast iron chain rate refractory brick surface wants slick and sly simultaneously, is difficult for scratching refractory fibre, the service life of having improved sealing device.
