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
Specific embodiment of the present utility model 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
Air inlet 41 and gas outlet 42 are equipped with, the connection of described air inlet 41 turns crystal formation furnace exhaust outlet connection, and gas outlet 42 then connects
To subsequent processing；The switch member 31 of described heating element heater 3 is connected with temperature sensor 16 with controller.
The bottom of the chain guide 2 of described heating furnace chamber 12 is provided with heating element heater 3.
The bottom of described described heating element heater 3 is provided with fan 21.
Described heating element heater 3 is PTC heater elements.
One kind described in the utility model prepares high purity aluminium oxide tunnel dehydration furnace, and it is pre- using electricity that it preheats furnace chamber 11
Heat, and the bottom of heating furnace chamber 12 is heated by heat entrained by turning crystal formation furnace gases product, due to turning the production of crystal formation furnace gases
Thing temperature is up to 800 DEG C, therefore it is enough as dehydration furnace heating source.Even if dehydration furnace is in the case of load is big, gas
For shortage of heat entrained by product to provide enough dehydration heats, the bottom of heating furnace chamber 12 still can coordinate electric heater unit to carry out
