technical scheme
The object of this invention is to provide one to be combined with wax removal kiln by sintering oven, being burnt completely by the wax cigarette produced in the waste heat in sintering process and de-waxing process is used for de-waxing, makes the ceramic member process units that whole production process is significantly energy-conservation.In sintering process, adopt two warm area sintering, low-temperature space utilizes gas fuel burning to sinter, and high-temperature region adopts molybdenum bar electrical heating to sinter, and has greatly saved electricity consumption.
A kind of ceramic member process units in conjunction with sintering oven and wax removal kiln, comprise electric-control system, wax removal kiln and sintering oven, wax removal kiln and sintering oven are side by side and product traffic direction is contrary, wax removal kiln comprises kiln body, product chamber, flue, quirk, chimney, the central authorities of kiln body are product chambeies, quirk surrounds product chamber, the entrance point of flue is communicated with product chamber, the port of export of flue is communicated with one end that quirk exports near wax removal kiln, quirk is communicated with chimney near one end of wax removal kiln import, sintering oven comprises electrical kiln and combustion chamber and feeder, combustion chamber was passed through burner and was communicated with the quirk of wax removal kiln.
Described wax removal kiln divides product chamber, upper strata and lower floor's product chamber.
Described chimney intake end is divided into two arms, and an arm is communicated with product chamber, upper strata, and an other arm is communicated with lower floor's product chamber.
Described flue has multiple entrance point.
Described feeder is gas generator or combustible gas direct-furnish.
During the work of this device, electric control system controls system cloud gray model, ensures that wax removal kiln and sintering oven product line run and the high temperature sintering work of electrical kiln and the low-temperature sintering work of combustion chamber; Feeder passes into combustible gas in combustion chamber combustion, and tail gas enters the quirk of wax removal kiln through burner, and electrical kiln heat transfer, using waste heat from tail gas and wax cigarette are burnt and to be heated to wax removal kiln product chamber; When wax removal kiln runs, the wax cigarette in product chamber is extracted out by flue and is delivered to quirk, is crossed burner flame ignition, outwards discharges after burning completely through chimney.
The invention has the beneficial effects as follows: sintering oven and wax removal kiln combine, and wax removal kiln no longer needs heater, significantly energy-conservation in production process; Wax cigarette in de-waxing process burns completely, without discharge, protects environment; Utilize combustion chamber to carry out low-temperature sintering, greatly save electricity consumption.

Detailed description of the invention
A kind of ceramic member process units in conjunction with sintering oven and wax removal kiln, comprise electric-control system, the wax removal kiln that product traffic direction arranged side by side is contrary and sintering oven, wax removal kiln comprises kiln body 3, product chamber 5, flue 2, quirk 4, chimney 1, the central authorities of kiln body 3 are the tunnel-shaped product chambeies 5 surrounded with refractory material, the quirk 4 closed surrounds product chamber 5, the entrance point of flue 2 is communicated with product chamber 5, the port of export of flue 2 is communicated with one end that quirk 4 exports near wax removal kiln, quirk 4 is communicated with chimney 1 near one end of wax removal kiln import, sintering oven comprises for the electrical kiln 8 of high temperature sintering with for low sintering combustion chamber 6 and feeder, combustion chamber 6 was passed through burner 7 and was communicated with the quirk 4 of wax removal kiln.
Wax removal kiln is divided into product chamber, upper strata and lower floor's product chamber.Chimney intake end is divided into two arms, and an arm is communicated with product chamber, upper strata, and an other arm is communicated with lower floor's product chamber.
Flue has multiple entrance point, entrance point is equipped with valve regulated flux magnitude.
Feeder is normal-pressure coal gas generating furnace, adopts mayor peak, Yixing machinery plant FJ-04.
One end that quirk exports near wax removal kiln exceeded burner, was in the cooling section of wax removal kiln; The port of export of flue connection quirk is in the high temperature section of wax removal kiln, but does not exceed burner; And flue is communicated with the import of entrance point near wax removal kiln in product chamber.
