Preferably, cold air inlet and hot-blast outlet are set on the cooling section, described cold air inlet is connected airduct with hot-blast outlet, and cold air inlet connects the natural wind blower fan by airduct, and hot-blast outlet is communicated with kiln combustion fan and preheating section by airduct.
Preferably, oxygen-enriched burning device comprises oxygen rich fuel gas burner, gas pipeline, oxygen-enriched combustion-supporting air duct.
The utility model is compared with existing combustion gas hot blast pottery oven dry burning kiln, has the following advantages:
1. realize the fume afterheat water conservancy diversion of burning kiln in the burner hearth of oven dry kiln, the fume afterheat of burning kiln is fully used, and the comprehensive energy consumption of burning kiln and dry kiln is reduced; Solved the problem that the existing burning kiln fume afterheat of existing combustion gas hot blast pottery, refractory material oven dry burning kiln is utilized and baking room burning kiln energy consumption is high.
2. the microwave hot air recombination energy pottery, the refractory material series of products drying and sintering machine that relate to of the utility model, floor space is little, has dwindled 30% through the preheating section length of overtesting kiln body, burns till segment length and has dwindled 20%; A large amount of occupation of land of the prior art, the thermal efficiency is low, product drying is not enough technical problem have been solved; Saved land resource greatly; Traditional drying sintering process equipment homogeneous heating and pure microwave drying sintering thermal efficiency height have been absorbed, the fireballing advantage of drying and sintering, problems such as traditional drying sintering process occupation area of equipment is big, the thermal efficiency is low, environment is abominable, and pure microwave drying sintering is inhomogeneous have been overcome.
3. furnace construction improves, and has thoroughly solved the problem ceramic, that refractory material is fired yielding cracking, and the product percent of pass height owing to preheating section, the section of burning till, cooling section shorten, is saved the energy and improved production efficiency simultaneously, has reduced toxic emission.
