Summary of the invention
In order to overcome the structural shortcoming of atmosphere furnace in the prior art, the utility model provides a kind of design of atmosphere furnace structure of modification, makes to insert and to take out materials and parts convenient, fast, to remedy the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of atmosphere furnace structure of modification, it mainly includes a siege, the siege bottom is provided with thermal insulation layer, described siege and thermal insulation layer outer rim are provided with inner furnace body, the big envelope device can seal the inner furnace body bottom, its siege bottom extension is provided with thermal insulation layer, and described inner furnace body and siege are provided with snap joint, with quick separation or in conjunction with inner furnace body and siege.
The beneficial effect of the utility model atmosphere furnace structure of modification is, can avoid seal component to cross cause thermal damage by present design, separate inner furnace body and siege fast, air inlet pipe is introduced the atmosphere gas of discharging in atmosphere gas and the blast pipe after using, from top to bottom make the atmosphere gas circulation, make the atmosphere gas circulation in the inner furnace body good, because siege is as the usefulness of putting assembly to be sintered, and the assembly that sintering is finished also is by taking out in the inner furnace body, so in charging, all inner furnace body to be separated with siege in the process of discharging, the design of its snap joint can make and insert, discharging is more convenient, fast.
