Accompanying drawing explanation
Fig. 1 is ceramic sintering electric kiln one example structure schematic diagram of the present invention.Fig. 2 is the electric heating body of ceramic sintering electric kiln of the present invention and the making die device one example structure schematic diagram of integrated heat-insulation liner plate.
Detailed description of the invention
In order to understand technical scheme of the present invention further, by following examples, the invention will be further described by reference to the accompanying drawings.
As illustrated in fig. 1 and 2, the ceramic sintering electric kiln of the present embodiment comprises in box body of heater 1, embeds heat insulation flue 2 in the shell body 6 of body of heater 1 and corresponding fire door 8 etc.Be placed in heat insulation flue 2 in box body of heater 1 to be connected and composed by the heat insulation liner plate 3 of corresponding monoblock (body) formula of body of heater inner chamber top, the end, left and right and rear side; The integrated heat-insulation liner plate 3 corresponding with the flue mouth of heat insulation flue is connected with in the interior sidewall surface of fire door 8.
The integrated heat-insulation liner plate of fire door 8, and the top of heat insulation flue, the end, left and right and rear totally five blocks of integrated heat-insulation liner plates 3 interior sidewall surface offer some corresponding pockets 4 respectively separately, be set around the top of the body of heater inner chamber of kiln, electric heating body 5 segmentation of downside wall and front, rear, left and right surrounding be embedded in respectively in the corresponding pockets of each corresponding integrated heat-insulation liner plate 3, with integrated heat-insulation liner plate and be made as integral type.Its side by body of heater inner chamber of each electric heating body 5 is exposed shape, the edge of its relative both sides adjacent with exposed side embeds in the two lateral walls of the pockets of (snapping in) corresponding integrated heat-insulation liner plate.
The integral type preparation method of its integrated heat-insulation liner plate and corresponding electric heating body comprises makes a monoblock type or modular by the heat insulating board such as heating wire and aluminosilicate refractory fiber, both energy-conservation, durable again.Namely use in comprising, the die device of outer two moulds, for the mould made in the pockets of integrated heat-insulation liner plate, die body 22 in groove type is set, and in groove type die body 22 two lateral walls on offer the corresponding shape with a relative two side portions of electric heating body (as helix tube type electric heating body), the long rabbet 23 that size is corresponding with length, again die body in groove type 22 is placed in the corresponding position in outer mold 21, corresponding helix tube type electric heating body is placed in the groove of die body 22 in each corresponding groove type, and it is outside to make these relative both sides of the edge (part) 5a two long rabbet 23 places of die body 22 in groove type of helix tube type electric heating body 5 protrude from the relative both sides of die body 22 in groove type, corresponding heat-insulating material is finally used to insert in outer mold 21, and then by the cooperation of inside and outside two moulds, electric heating body (as helix tube type electric heating body) and integrated heat-insulation liner plate are made as integral type.To be produced shaping after, namely the electric heating body edge 5a of this relative two side portions of helix tube type electric heating body is embedded into and is fixed in integrated heat-insulation liner plate, both energy-conservation, durable again.
Integrated heat-insulation liner plate can be made by alumina silicate heat-insulating material and form hard formula or soft.The heat insulation liner plate of rigid unitary formula can also be formed by making containing zirconium alumina silicate or mullite heat-insulating material.Its electric heating body and integrated heat-insulation liner plate making structure is set; can protect electric heating body indeformable, do not come off; not fragile; simultaneously; effectively can improve heat utilization efficiency; and relatively can reduce the thickness of integrated heat-insulation liner plate, to reduce the volume of whole kiln, there is responsiveness and the control accuracy of very high firing temperature control.
Be provided with concave station face 7 in the surrounding end wall surface of the flue mouth corresponding with fire door 8 of heat insulation flue 2, the integrated heat-insulation plate on fire door 8 is by the embedded joint of heat insulation flue in this concave station face and body of heater 1.Can further improve the heat insulating effect of kiln.
In another embodiment of the invention, the heat insulation flue in body of heater can make in by alumina silicate, form containing zirconium alumina silicate and/or mullite heat-insulating material, comprise the end, top about and the integrally insulating flue of rear wall.All the other structures of the present embodiment and preparation method can with above-described embodiment roughly the same.
The heat absorption of its kiln body material of ceramic sintering electric kiln of the present invention is directly proportional to the density of its material, and the density of existing light mullite brick is 600 ~ 800kg/m
3, and the density of alumina silicate or mullite flame-proof fiberboard is 320 ~ 350kg/ m
3, therefore energy-saving effect is remarkable, and meanwhile, because the heat absorption of kiln body is few, therefore thermal inertia is little, and also very accurate to the regulation and control of kiln temperature, make kiln temperature difference become very little, temperature control is accurate, thus substantially increase goods burn till quality.
Simultaneously both energy-conservation, durable again by heating wire and alumina silicate or mullite flame-proof fiberboard being made an entirety (being made into module in other words).From durable angle, heating wire is effectively inlayed fixing, has excellent thermal shock resistance, and intensity is good, can not skid off from groove, long-life low maintenance.The modularization of heating and heat-barrier material, also the brick-building art of body of heater is made greatly to simplify, save man-hour, reduce labour intensity, avoid the suffering that operating personnel obtain sunset tuberculosis, simultaneously, same volume, the kiln of identical temperature class, its overall dimensions are more much smaller than traditional kiln, also just save steel and refractory material.
