Abstract

The utility model relates to an industrial oven door, consisting of a hollow door sheet whose section is caved, an insulating layer bottom plate and a plurality of insulating layer protruding plates; the edges of upper end and lower end of door sheet are provided with a plurality of heat elimination holes with equal distance; a thermal insulation chamber with proper space is provided between the insulating layer bottom plate and inner surface of door sheet, and the back of the insulating layer bottom plate is provided with the insulating layer protruding plate; this structure can isolate high temperature in the oven and can provide thermal insulation effect; moreover, high temperature is isolated by the isolation chamber of door sheet, and then the accumulated heat and high temperature are discharged through the heat elimination holes, thus effectively reducing the temperature of door sheet surface and guaranteeing the safety of operator; the weight is reduced, thus reducing the load of operator, avoiding or reducing the work fatigue and so on.

Description

Industry baking box chamber door

The utility model relates to a kind of industrial baking box chamber door.

As everyone knows, the employed industrial baking box of tradition, the setting of its door-plate is the insulation material that coats multilayer with metal sheath, its function only is that thermal source is completely cut off in baking box inside, and owing to be directly to coat to contact between insulation material and the door-plate, add the isolated thermal source of insulation material its certain restriction is arranged, and can produce thermal phenomena, therefore thermal source can be directly conducted to the door-plate outside, and the temperature of door-plate can very high (about 50 ℃-90 ℃), the as easy as rolling off a log operating personnel's scalded skin that makes of its high temperature, security may be poor.

The baking box door-plate that also has, because ask effectively isolated thermal source to expose,, so will cause door-plate weight quite thick and heavy so can coat insulation material multiple, multilayer, if the unlatching of door-plate, to close number of times too frequent, then can cause the excessive easy fatigue of operating personnel's physical load.

The purpose of this utility model is to provide a kind of and can completely cuts off high temperature in baking box and have its heat preservation effect, and can make the temperature on door-plate surface to effectively reduce, and security is good; Lightweight industrial baking box chamber door.

The purpose of this utility model is such realization: it is mainly formed by having hollow door-plate, a heat-insulation layer base plate and the heat-insulation layer flange more than that a cross section is concavity; And door-plate is positioned at, the equidistant louvre that is provided with of following two ends lateral margin, maintain the heat-insulating room in suitable space between this heat-insulation layer base plate and the door-plate inner face, then folded this slow-witted temperature layer flange of establishing at the back side of heat-insulation layer base plate, utilize the heat-insulation layer flange that high temperature is blocked in the baking box body to reach heat preservation effect, the long-pending heat of heat-insulation layer flange then sees through the heat-insulation layer base plate and conducts to heat-insulating room, and the louvre via door-plate utilizes the cold-hot air convection guide to go out heat-insulating room high temperature, and unlikely amassing on door-plate, make the temperature on door-plate surface can effectively remain on the thermophilic state with this, guarantee operating personnel's safety.

The utility model has following advantage compared to existing technology: can completely cut off high temperature in baking box and have outside its heat preservation effect, and door-plate is isolated high temperature by isolation ward, to amass hot high temperature guide by louvre again leaves, make the temperature on door-plate surface to effectively reduce, to guarantee safety of operators; Weight reduces, and makes operating personnel's minimizing of loading, and avoids or reduces work fatigue etc.

The drawing of accompanying drawing is described as follows:

Fig. 1 is an exploded perspective schematic diagram of the present utility model,

Fig. 2 is the utility model combination generalized section,

Fig. 3 is the example structure schematic diagram of the utility model collocation baking box body.

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing: door-plate 1, heat-insulation layer base plate 2, thermal insulation ceramics pad 3, bed hedgehopping seat 12, keyhole 22, heat-insulation layer flange 4, ventilation slot 21, louvre 11, keyhole 41, baking box body 5, heat-insulating room 10, packing bar 51, long-pending hot H, fixing threaded hole 23,

bolt

24,42, screw 121.

As depicted in figs. 1 and 2, include hollow door-plate 1, the one heat-insulation layer base plate 2 that a cross section is concavity, several thermal insulation ceramics pads 3 and some heat-insulation layer flanges 4 are formed.Door-plate 1 of the present utility model is in equidistant several louvres 11 that is provided with of upper/lower terminal lateral margin, the some appropriate locations of edge are provided with bed hedgehopping seat 12 around the inner face and door-plate 1 is positioned at, on bed hedgehopping seat 12 median planes, be provided with screw 121, close on four peripheral regions at heat-insulation layer base plate 2 in addition and establish several equidistant ventilation slots of arranging 21, and keyhole 22 and fixing threaded hole 23 are set respectively in some appropriate locations of periphery, and each heat-insulation layer flange 4 then is provided with keyhole 41 in fixing threaded hole 23 appropriate locations of relative heat-insulation layer base plate 2.

The utility model mainly is to utilize the keyhole 22 of heat-insulation layer base plate 2 to place with bolt 24, be nested with thermal insulation ceramics pad 3 on one's body respectively in each bolt 24 bolt again, and with bolt 24 locking on the screw 121 of bed hedgehopping seat 12, make and keep a suitable heat-insulating room 10 between heat-insulation layer base plate 2 and the door-plate 1 Inner face, in addition, 4 of heat-insulation layer flanges are placed by keyhole 41 with bolt 42, and revolve on the fixing threaded hole 23 that is locked in heat-insulation layer base plate 2

As shown in Figure 3, its heat-insulation layer flange 4 can give tight packing with the packing bar 51 on 5 edge of baking box body, and door-plate 1 promptly can make heat-insulation layer flange 4 that high temperature is completely cut off in baking box body 5 inside after cutting out, to have good heat insulation effect; The long-pending hot H of heat-insulation layer flange 4 then sees through heat-insulation layer base plate 2 and conducts to heat-insulating room 10, and the long-pending hot H guide of high temperature is left outside the heat-insulating room 10 via the louvre 11 of door-plate 1, and unlikely amassing on door-plate, make the temperature on door-plate 1 surface can remain on the thermophilic state effectively with this, guarantee the security that operating personnel work.The utility model door-plate 1 is owing to have the diffusing long-pending heat energy power of removing, can reduce use heat insulation material, except can reducing cost, make door-plate 1 whole weight saving relatively, operating personnel's load can be reduced, and the tired phenomenon of avoiding giving birth to due to 1 open and close of frequent operation door-plate takes place.

In addition, aforementioned long-pending hot H in heat-insulating room 10, main is to utilize cold and hot convection action, just hot-air up and cold air effect is down discharged toward top louvre 11 fast and will amass hot H.
