What the emerging pottery of mud fired pottery use in the early time is kilns such as imperial kiln, down-draft kiln, tunnel cave, and what use now mainly is electrical kiln or gas kiln, is that reduction is burnt till; Its principle is: the interior oxygen supply of kiln was insufficient when utilization was burnt till; Be in barotropic state in the kiln, fuel can not fully burn, and produces smog; Make carbon monoxide in metal oxide and the kiln in the potter's clay combine that (for example copper oxide reduction becomes cuprous oxide; Color becomes green), the parts that will between two parts that separate, contact before burning till are pounced on aluminium powder, in case the bonding phenomenon takes place in sintering procedure.When greenwave being installed on the stove car, blanket will keep balance, and base substrate wants strictness to be in same horizontal plane.After installing, follow the riding position resultant whether of the principle check greenwave of " transverse joint will will lead to, perps, outer tight hollow, last close rare down ", irrational will at once the adjustment.After the check, can the stove car slowly be pushed furnace chamber, close wicket, energising is fired.The time of firing is generally the time about 20h, and temperature reaches about 1200 ℃ in stove, but the time ability kiln discharge that the outage back lowers the temperature about two days naturally.In the existing this method for cooking; But the time ability kiln discharge that needs nature to lower the temperature about two days after the outage; The heat that is equivalent to distribute this temperature-fall period from 1200 ℃ to intimate normal temperature wastes, and this not only causes the raising of production cost, on the other hand; Also because the pottery that burns till must be accomplished to lower the temperature in firing kiln also extends manufacture cycle, this is a factor that causes the production cost high equally.

The utility model content

The technical problem that the utility model will solve provides a kind of energy-conservation ceramic sintering equipment, and this device structure is simple, adopts this equipment effectively energy savings that fires pottery, and reduces production costs.

The described energy-conservation ceramic sintering equipment of the utility model; It comprises carries out the holding furnace of preheating and fires kiln to what the greenwave after the preheating was fired greenwave; Be provided with a dividing plate in the burner hearth of said holding furnace; This dividing plate is separated into two independently first chamber and second chambers with burner hearth, offers at least one through hole on the described dividing plate to realize the circulation of two chamber air.

Described through hole can be arranged arbitrarily on dividing plate, preferably is arranged; The diameter of said through hole is generally 8～20cm, and this moment, the centre-to-centre spacing of adjacent two through hole was 10～25cm in the horizontal direction, and the centre-to-centre spacing of adjacent two through hole is 10～25cm on the vertical direction.

The described kiln of firing is to fire the conventional electric kiln that uses when mud is emerging makes pottery, and individuality can be a shuttle kiln.

Compared with prior art; The said device structure of the utility model is simple; Through burner hearth being divided into two chambers with the dividing plate that is provided with through hole, greenwave and the pottery of firing completion are placed two chambers respectively, the heat that the pottery that utilizes completion to fire distributes when cooling carries out preheating to the greenwave that is about to fire; Not only practiced thrift the energy; And, make it certainly will be able to reduce conduction time firing in the step of postorder because greenwave is preheated to uniform temperature in advance, when reducing production costs, shorten the production cycle; In addition,, after completion is burnt till, promptly from kiln, take out, thereby make that firing kiln can begin firing of next round again, improved the utilization rate of equipment, reduced production cost from another aspect owing to fire the pottery that bakes in the kiln.
