During boundary's air pressure, in the very empty easy entrance furnace chamber of outside air, cause the product in furnace chamber to aoxidize, influence product quality.
Number of patent application 2014100947355 discloses a kind of Muffle furnace that can effectively prevent outside air from entering in furnace chamber
On exhaust apparatus, furnace chamber is provided with body of heater, the air inlet of the blast pipe is connected with furnace chamber, the gas outlet of the blast pipe and
Closed Drain system connectivity.The Closed Drain system, which includes, is provided with water or other liquid, blast pipe in tank, the tank
Gas outlet be located in the water in tank or other liquid.The air inlet of the blast pipe is connected with earthenware one end, earthenware
The other end is connected with furnace chamber.The height that the tank is set is less than at the top of furnace chamber.Also include on vertical pipe, the gas outlet of blast pipe
Face is provided with solid matter valve, and vertical pipe one end is connected with the blast pipe above solid matter valve, and the other end of vertical pipe is provided with inline valve
Men Bingyu atmospheres.The present invention is because outside air by water segregation because cannot be introduced into furnace chamber, it is to avoid carbonisation product
Oxidation, improves the yield rate and covered effect of product carbonization.
But, can not be to discharging the oxygen in furnace chamber well although it, which isolates outside air, enters furnace chamber.
The content of the invention
In order to solve one of defect present in above-mentioned prior art, there is provided the new anti-oxidation Muffle furnace of one kind.
The utility model solves the technical scheme that its technical problem used:
There is heat-insulation layer and furnace chamber in a kind of new anti-oxidation Muffle furnace, including body of heater, body of heater, furnace chamber bottom and/or on
