For guaranteeing temperature homogeneity and heat insulation best effect in the lehre stove, in the work-ing life of extension fixture, furnace lining is a bilayer structure, and its skin is a compression aluminum silicate fiber module, and internal layer is the cotton plate of aluminum silicate fiber acupuncture.On the furnace shell wall, lay the thick needle punched blanket of one deck 50mm earlier and make thermal insulation layer, good as refractory insulating layer fibre module again with bolt.
The top is the circular arc arch on the tank body of retort; Jar mouthful place of retort is connected with fire door through water-chilling plant, is provided with the multiwalled thermoscreen in jar mouth.Roof pressure on the tank body is processed the circular arc arch, can play the effect of strengthening support; And the multiwalled thermoscreen can be sealed temperature in the stove.Retort adopts existing Muffle pot.
As a kind of improvement project of the present invention, silicone rubber O-ring is adopted in the sealing between fire door and the water-chilling plant.
As a kind of improvement project of the present invention, also be provided with on the water-chilling plant and detect jar thermopair interface arrangement and the gas barrier of interior temperature.
As a kind of improvement project of the present invention, bottom of furnace body is provided with flame-retardant fibre board or the light-weight mullite brick is done backing.Be laid between the globars with flame-retardant fibre board or light-weight mullite, can be used for supporting retort.
In order to enlarge the heating area of heating unit, improve the homogeneity of heating, heating unit adopts globars, in the retort rectilinear installation of level or both sides up and down, and arranges along retort outside phase-splitting.Horizontal is installed heating unit about retort, can shorten radiation length, improves temperature homogeneity, reaches optimum energy-saving effect.
As a kind of improvement project of the present invention, system comprises detecting unit, the program adjusting apparatus that is connected with the output terminal of detecting unit, and the programmable logic controller that is connected with program adjusting apparatus input terminus; Said detecting unit comprises three thermopairs, and three thermopairs lay respectively at before, during and after the burner hearth.Thermopair is used to measure the temperature in the burner hearth, makes system in time regulate the temperature in the burner hearth according to need of work, before, during and after burner hearth, respectively establishes a thermopair, helps further improving the temperature homogeneity in stove Nei Ge district.
Advantage of the present invention is: simple in structure, can in time regulate Heating temperature as required, heats is even, and production efficiency is high, and installation easy to use.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in Figure 1, the furnace lining 2 that the present invention includes body of heater 1, fits with body of heater 1 inwall, the retort 4 that is positioned at body of heater 1, and with the heating unit 5 of retort 4 internal communication; Body of heater 1 front end is established fire door, and the jar mouth of retort 4 stretches out fire door, and and fire door between for being tightly connected, a jar mouthful place also establishes fire door 7, is connected through water-chilling plant 6 between fire door 7 and the jar mouth; Heating unit 5 is connected with the system of peripheral hardware, regulates the temperature of heating unit through system.
Aforementioned body of heater 1 shell adopts Q235 steel plate and shaped steel to be welded, and said body of heater 1 top is provided with opening, and opening part is established furnace top cover 3, is connected through bolt between furnace top cover 3 and the opening.
Aforementioned furnace lining 2 materials adopt plug to draw aluminum silicate fiber module and aluminum silicate fiber needle punched blanket, and promptly needle punched blanket is made thermal insulation layer after laying one deck 50mm earlier on body of heater 1 inwall, and is good as refractory insulating layer with bolt fibre module again.
Lay with flame-retardant fibre board or light-weight mullite body of heater 1 bottom, is used to support retort 4.
System comprises detecting unit, the program adjusting apparatus that is connected with the output terminal of detecting unit, and the programmable logic controller that is connected with program adjusting apparatus input terminus; Said detecting unit comprises that 9, three thermopairs 9 of three thermopairs lay respectively at before, during and after the burner hearth.Aforementioned program adjusting apparatus adopts existing KP program temperature controller.
