Abstract
The utility model discloses a five-surface heating box type electric furnace, which comprises a furnace casing, a furnace door, an insulation masonry and a heated filament, and is characterized in that the heated filament is placed in a left side surface, a right side surface, a furnace back side, a furnace bottom and a furnace back side of the box type electric furnace. Compared with the prior art, the five-surface heating box type electric furnace has an obvious advantage that the five-surface heating can be realized, the temperature difference in the furnace can be reduced, the quality of the roasted product can be fully guaranteed; the temperature hysteresis quality can be largely improved due to direct heating by open fire, the electric furnace is in favor of the control of the furnace temperature, and enables energy saving; and the reasonable installation and layout of the heat-generating body is convenient for installation and maintenance.
Description
Technical field
The utility model relates to electric heater unit, particularly a kind of cabinet-type electric furnace.
Background technology
The heating technique of existing cabinet-type electric furnace generally has two kinds:
1) two sides heated type
The heater of this stove and arranged on left and right sides in stove.Characteristics are simple in structure, and easy mounting is with low cost.
If but the shortcoming heating wire is when being installed in the stove both sides, the product radiation in the middle of heat is positioned at from two side direction causes burner hearth both sides temperature drift, and positive, the temperature of the back side and bottom surface is on the low side.If to the burner hearth thermometric, then the each point temperature difference is more obvious by " 9 thermometry ".
2) Muffle furnace courage formula
Muffle furnace courage formula batch-type furnace is to adopt refractory ceramics to be made into flue, outside flue, twines heating wire, and energising back heating wire is earlier to the flue heating, and flue is transmitted to burner hearth (dying fire heated type) to heat through heat exchange pattern.Characteristics: realize that heat simultaneously at the left and right sides, bottom and top in the stove, the uniformity of temperature is improved preferably.
Its shortcoming is:
1. since the conduction of its heat energy be earlier the heating flue again radiation give product, so temperature has bigger hysteresis quality, energy consumption is also bigger;
2. have only both sides, bottom and the top heating of burner hearth, chamber door and box back surface do not have thermal source, and the uniformity of temperature also is not too desirable;
3. temperature is prone to assemble to the top in the principle that makes progress naturally according to heat, stove, causes head temperature too high, and heating wire blows easily;
4. because its structural reason, when changing hair, need stove in masonry remove, be not easy to install, more be not easy to maintenance.
Summary of the invention
For solving the problems of the technologies described above, the purpose of the utility model provides a kind of cabinet-type electric furnace of five heating, and it can solve the burner hearth uniform problem of being heated, and reaches the uniformity requirement of temperature.
The purpose of the utility model is achieved in that a kind of cabinet-type electric furnace of five heating; Comprise stove outer covering, fire door, insulation masonry and heating wire, it is characterized in that: described heating wire is arranged at the position at left surface, right flank, the stove back side, furnace bottom and the fire door back side in the box burner hearth.
Described heating wire is placed in five groups of refractory ceramics Guan Shanghou, is arranged at the position at left surface, right flank, the stove back side, furnace bottom and the fire door back side in the box burner hearth respectively.
Said stove outer covering medial surface and the fire door back side are built and are established heat-insulation layer, and the surface that the side of heating wire is installed at needs is provided with special-shaped exotic material layer, forms whole insulation masonry, and heating wire is inserted in the outer and integral body of refractory ceramics pipe and is inlaid on the insulation masonry.
Said heat-insulation layer comprises multilayer, the setting of staggering of the masonry crack between every layer.
Described special-shaped exotic material layer is the frame type, and the frame inboard of special-shaped exotic material layer is fixed at refractory ceramics pipe two ends.
The utility model compared with prior art has clear superiority: realized five heating, thereby reduced the temperature difference in the stove, fully guaranteed to fire the quality of product; Owing to be that naked light directly heats, temperature lag property is improved greatly, more helps the control of fire box temperature, and is also more energy-conservation; The rational mounting arrangement of heater both had been convenient to install, and also was convenient to maintenance.

The specific embodiment
As shown in Figure 1, the utility model is a kind of cabinet-type electric furnace of five heating, comprises Funnel Cover 1, insulation masonry 2, heating wire 3, stove outer covering 4 and fire door 5 etc.Stove outer covering 4 adopts steel stove outer covering, single open-door formula structure.Shown in each figure; Heating wire 3 is arranged at the position at left surface in the box burner hearth, right flank, the stove back side, furnace bottom and the fire door back side, realized Muffle furnace courage formula batch-type furnace the heating at irrealizable fire door and the stove back side, and heating wire is directly installed in the burner hearth; Adopt the naked light mode of heating; Effectively improve the hysteresis quality of temperature, and need not to remove the insulation masonry when installing, very convenient.Do not establish heating surface in furnace roof portion, avoided the too high and problem of frequently blowing heating wire of head temperature.In the present embodiment, heating wire 3 is placed in back (as shown in Figure 5) on five groups of refractory ceramics pipes 6, is arranged at the position at left surface, right flank, the stove back side, furnace bottom and the fire door back side in the box burner hearth respectively.
Five and the fire door back side are built and are established heat-insulation layer in the said stove outer covering; That several side of heating wire being installed at needs surface is special-shaped exotic material layer 21; Form whole insulation masonry 2, heating wire 3 is inserted in refractory ceramics pipe 6 outer also integral body and is inlaid on the insulation masonry 2.For example in the present embodiment, special-shaped exotic material layer 21 is the frame type, and the frame inboard of special-shaped exotic material layer 21 is fixed at refractory ceramics pipe 6 two ends.Heat-insulation layer can comprise multilayer, and the thickness and the number of plies can suitably be thickeied or attenuate according to actual serviceability temperature height.The setting of staggering of masonry crack between every layer, lost to prevent that heat from directly penetrating.
During preparation, around stove outer covering 4 internal layers, reach outer block of fire door earlier and make heat-insulation layer, build special-shaped exotic material layer 21 and the block doing to have made at innermost layer then and make furnace roof, thereby form whole insulation masonry 2; Be inserted in earthenware 6 outer also integral body to heating wire 3 again and be embedded on the insulation masonry 2, so far accomplish the block of whole five heated type batch-type furnaces and make process.
