Abstract

The utility model relates to a box type high-temperature furnace belonging to the heating device class. The utility model mainly relates to the field of electric heating devices of labs. The utility model solves the problems of large volume, heavy weight, inconvenient disassembly and assembly and maintenance, and easy ablation and exfoliation of paint coat layer of a housing because of high temperature of the existing high-temperature furnace. The utility model has the technical proposal that a furnace hearth port of an oblong housing (1) of a furnace hearth is provided with a door frame type refractory bricks; the tail end wall is provided with a stack nozzle (4) and a thermocouple port (5); the oblong housing of the furnace hearth device is arranged in an inner liner housing (2) of the furnace body larger than oblong housing of the furnace hearth device; the horizontal axis of the oblong housing of the furnace hearth is coincident with the horizontal axis of the inner liner housing of the furnace body; a heat-insulating layer (3) made of cellucotton is filled in the space between the oblong housing of the furnace hearth and the inner liner housing of the furnace body; an inner liner of the furnace body is composed of the oblong housing of the furnace hearth, the heat-insulating layer, and the inner liner housing of the furnace body; a housing (7) with a larger size than the inner liner of the furnace body and the inner liner of the furnace body are assembled on a bottom plate (8) in a coaxial line. The utility model is mainly applicable for coal industry, chemical industry, electric power industry, metallurgy industry, etc. The utility model can also be used in laboratory for sintering, heating, heating chemical analysis, etc.

Description

The novel box type high temperature furnace

(1) technical field: the utility model belongs to the heating instrument class, relates generally to laboratory electrical heating instrument field.

(2) background technology: current coal, electric power, metallurgy, the used box high temperature furnace in chemical industry experiment (test) chamber, rise and constant temperature for guaranteeing that furnace temperature is fast, all block is formed by the metal shell packing after light fire brick is arranged again outside hearth housing, because the light fire brick heat insulation effect is limited, so just causing owing to what be incubated needs the light-weight refractory brick setting thicker, cause volume big, body weight is big; Can cause the shell enamelled coating to ablate reduction of service life again if refractory masonry is thin slightly; After burner hearth endogenous pyrogen stove silk scaling loss, change the stove silk and must tear the stove replacing open, bring a lot of inconvenience to maintenance.

(3) summary of the invention: technical problem to be solved in the utility model is: guaranteeing to dwindle this stove overall dimensions, weight reduction under the not variable situation of box high temperature furnace quick heating, constant temperature; Once the stove silk damages, be convenient to maintain and replace, make the shell enamelled coating can not cause ablation to come off by Yin Gaowen simultaneously, keep the elegant in appearance of this stove external form.

Solve the technical scheme of the above technical problem: the hearth housing mouth at the rectangle burner hearth housing of being with pyrotoxin is equipped with the fire-resistant shaped brick of door case type, be shaped on throat and thermocouple port on the tail end wall, rectangle burner hearth casing device is in the body of heater inner bag shell greater than it, the horizontal axis of the horizontal axis of rectangle burner hearth housing and body of heater inner bag shell coincides, space between rectangle burner hearth housing and the body of heater inner bag shell is filled with the cellucotton heat-insulation layer, by rectangle burner hearth housing, the cellucotton heat-insulation layer, body of heater inner bag shell is formed the body of heater inner bag, greater than the shell of body of heater inner bag size and being assembled on the chassis of body of heater inner bag same level axis.

The beneficial effects of the utility model: 1, because the utility model changes heat-insulation layer into the fiber cotton heat-insulation layer by light fire brick, because cellucotton heat-insulation layer high insulating effect, the insulation layer thickness that dwindled in light weight has realized that volume is little, lightweight purpose; 2, because the cellucotton heat-insulation layer is convenient to dismounting, the heating cooking stove silk in rectangle burner hearth body can in time be extracted rectangle burner hearth housing out after damaging, and changes the heating cooking stove silk, brings convenience to maintenance; 3, because the body of heater inner bag is cased and and shell between leave certain clearance, make box high temperature furnace in use surface of shell be difficult for to ablate, realized in use keeping the generous purpose of appearance looks elegant.

(4) description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right diagrammatic sketch of Fig. 1.

(5) specific embodiment:

With reference to Fig. 1, Fig. 2, the hearth housing mouth that the rectangle burner hearth housing 1 of heating resistor line is housed is equipped with the fire-resistant shaped brick 6 of door case type, be shaped on throat 4 and thermocouple port 5 on the tail end wall, rectangle burner hearth housing 1 device is in the body of heater inner bag shell of being made by steel plate 2 greater than it, the horizontal axis of the horizontal axis of rectangle burner hearth housing 1 and body of heater inner bag shell 2 coincides, aluminosilicate fiber cotton heat-insulation layer 3 is filled in space between rectangle burner hearth housing and the body of heater inner bag shell, by rectangle burner hearth housing, the cellucotton heat-insulation layer, body of heater inner bag shell is formed the body of heater inner bag, steel shell 7 greater than body of heater inner bag size is assembled on the chassis 8 with body of heater inner bag coaxial line, top and the side of shell 7 is shaped on slotted hole 9, also have the plastic-blasting rete on the surface, the shell at stockhole place and the metal of fire door part are made by corrosion resistant plate.Chassis 8 is a flute profile, is shaped on slotted hole 9 on the cell wall.
