Brief description of the drawings
Fig. 1 is a kind of sectional view for preparing high purity aluminium oxide tunnel dehydration furnace；
Fig. 2 is A-A direction views in Fig. 1.
Embodiment
The embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
One kind as shown in Figure 1 prepares high purity aluminium oxide tunnel dehydration furnace, including body of heater 1, chain guide 2 and heating unit
Part 3, the inside of body of heater 1 are the furnace chamber of tunnel type, and described furnace chamber is divided into three sections, respectively preheats furnace chamber 11, the and of heating furnace chamber 12
Cool down furnace chamber 13；The roof and side wall of furnace chamber set the inwardly protruded thermal resistance beam 14 of multiple tracks, the roof of described furnace chamber be provided with to
Few 1 steam vent 15；Chain guide 2 runs through furnace chamber, and heating element heater 3 is arranged on the bottom of the chain guide 2 of preheating furnace chamber 11；Institute
The furnace chamber top stated is provided with temperature sensor 16, and the chain bottom of described heating furnace chamber 12 is provided with coiled pipe 4, and coiled pipe 4 is set
