Abstract
The utility model relates to a gate mechanism for an industry furnace. The utility model is composed of channel steel tracks (or support boards), a wheel axle, a heavy hammer, a furnace casing, and convex refractory material. The channel steel tracks (or support boards) are arranged on both sides of a furnace fate, and the angle alpha between the channel steel tracks and the outer casing of the furnace is 8 DEG to 88 DEG. When the furnace gate is opened or closed, the utility model can moved up and down freely no matter manual driving or powered driving, and operation procedures are reduced; in addition, the convex refractory material body enhances the sealing performance and service life of the furnace; The utility model is suitable for various industrial furnaces.
Description
The utility model is a kind of fire door mechanism of used for industrial furnace, is applicable to various industrial furnaces: ir resistance furnace, various box, car-types, tunnel type resistance furnace and Fuel Furnace.
In the prior art, general fire door can only parallel fire door vertical lift, and towards the fire door inboard of burner hearth, refractory material does not put in the burner hearth (Fig. 5), and fire door and stove outer covering are gapped, and furnace heat is excessive, has increased thermal losses.
A kind of experimental electric furnace be side open the door (Fig. 6) though have convex refractory brick to put in the fire door, poorly sealed, thermal loss is also arranged.The structure that side is opened the door makes the direct excessive face of pouncing on of the interior hot gas of stove when opening fire door, influences workman's operation.
Fire door pattern (Fig. 7) in the Chinese patent 86206964.5, the problem that exists at former fire door, but a kind of push-and-pull and liftable fire door mechanism have been proposed, rely on outstanding soft refractory fibrous material, go deep into fire door 50～100mm, stop that the interior hot-fluid of stove is excessive.Soft refractory fibre is like this being adorned, is very easily being broken when coming out of the stove, and furnace life is reduced.In addition, fire door is when opening, will be earlier with manually drawing handle of fire gate, again manually or the electric hoist fire door, the wheel shaft of the fire door left and right sides could withdraw from along arc track, is retracted into vertical lifting behind the vertical section, and the groove steel rail mechanism that this mechanism adopts makes fire door must lean on artificial push-and-pull pressure handle when opening or closing, the fire door lifting has increased operational sequence not freely.
The purpose of this utility model provides a kind of lifting freely, manually the mechanism of fire door can be opened or close to the push-and-pull pressure handle just, adopt specific refractory material and seal approach around stove outer covering and the fire door, stove gate shell temperature rise ratio national standard is reduced more than 70 ℃, reach energy-saving effect.
For reaching this purpose, the utility model is provided with inverted Y-shaped groove steel rail (or supporting plate) at two at fire door, with the stove outer covering tilt angle alpha be 8 °～88 °, fire door by the deadweight by all liftings freely of manual or electronic mode.
The fire door mechanism that adopts groove steel rail with 5～［ 30 channel-section steels are made, and are provided with the wheel shaft that diameter is slightly less than grooved rail in the groove steel rail.If fire door mechanism supporting plate, then supporting plate is the thick steel plate of 3～50mm.Y type well width D is 36～273mm, and supporting plate can directly be fixed on the stove shell by two bolts.Because grooved rail does not have the right angle part, wheel shaft along the lifting very freely of inverted Y-shaped groove, does not need artificial push-and-pull fire door with fire door in the grooved rail, can open smoothly or close.
Fire door is equipped with the convex soft refractory towards the side of burner hearth and puts in the stove, and with the high-temperature alloy net soft refractory (or refractory brick) is encased, and protection is adorned, do not broken when coming out of the stove.For solving the excessive problem of hot gas,, improved the stove sealing property and made stove gate temperature rise ratio national standard reduce more than 70 ℃ with iron-clad boundary around convex refractory material and the stove gate on the fire-resistant soft fibre sealing door.
Cooperate door opened with close, fire door is close to the stokehold outward and is provided with the weight that a plurality of semi-cylindricals are formed by stacking along shell and moves up and down.Weight is made by casting pig, and movement weight mass number (being quantity) is pressed fire door weight to be increased or reduce.
It is 8 °～88 ° structure that the utility model has adopted tilt angle alpha between inverted Y-shaped groove steel rail (or supporting plate) and the furnace shell, can solve the fire-resistant body of convex and stretch into when also having solved 86206964.5 utility model industrial furnace fire doors in the fire door and opening or close, simplify operational sequence with the problem of artificial push-and-pull and lifting inconvenience.Strengthened heat-insulating property.Make stove increase heat-insulating property because the utility model is asked at the fire door face on the refractory material of burner hearth inboard with the fire-resistant soft fibre of high-temperature alloy net and good seal again, prolonged service life.There is the combination movement weight mass to provide the convenience of regulating again for the fire door lifting.

The utility model is described in further detail below in conjunction with drawings and Examples.
Fire door mechanism of the present utility model (Fig. 1) is made up of groove steel rail (or supporting plate) mechanism 2, power transmission shaft 3, stove gate 5, stove outer covering 6, convex refractory material 4 etc.When door opened or when closing, the track wheel shaft 1 that is fixed together with fire door slides in inverted Y-shaped groove steel rail (or supporting plate 2), rise or descend with fire door, make the fire door lifting freely.The fixed head 9 of groove steel rail and stove gate shell (Fig. 2) is connected by bolt, and the grooved rail width D is 36～273mm.If adopt supporting plate mechanism (Fig. 3), then supporting plate directly and stove outer covering fix with nut, inverted Y-shaped wheel shaft slideway 10 width in steel plate 11 is the same with the grooved rail width to be D.Adopting groove steel rail still is that supporting plate all will be fixed with stove outer covering, and the angle of inclination is α between 8 °～88 °, and this angle will stretch into furnace depth towards burner hearth side convex refractory material 4 on fire door and decide.For protection convex refractory material is being adorned, be not damaged when coming out of the stove; encase its surface with high-temperature alloy net 12; for preventing that fire door and furnace shell gap location from having hot gas excessive; iron-clad boundary seals with fire-resistant soft fibre 13 around convex refractory material and stove gate; the stove gate temperature rise is reduced, reach energy-saving effect.In order to cooperate door opened or to close, fire door is close to the stokehold outward and is provided with combination movement weight mass (Fig. 4) along shell, movement weight mass is formed by a plurality of semi-cylindrical casting pig 12 accumulations, weight after the combination is the semicircle cylinder, the combination weight that is connected with power transmission shaft 3 when the fire door lifting moves up and down, drive door opened or close, movement weight mass number (being weight) will increase or reduce by fire door weight, and the combined type weight is that weight is regulated and provided convenience.
