For strengthening passing into outer gas stream, on the top of described stir shaft, breather is installed, comprise bearing, conduit coupling and safety valve.
Height for integral body adjustment stirring module is provided with mobilizable lifting rod on described bracing frame, and lifting rod one end is connected with the power set that stirs module.
In production practice, described agitating vane is preferably installed two pairs, and the one pair of blade that is fixed on stir shaft one end at the bottom of near burner hearth is called primary blades, and another pair of moving vane is installed on primary blades, is called back blades.
Compared with prior art, advantage of the present invention is as follows:
1. adopt the churned mechanically mode that adds on body of heater, and further adopt the design of multipair agitating vane and moving vane, make powder body material upset more abundant, reduced the phenomenon that hardens in high-temperature oxidation process, powder body material oxidation is more even, the more excellent performance of products obtained therefrom;
2. adopt the interior ventilation design of novel axle of hollow stir shaft and corresponding breather composition, can effectively control the add-on of gas, also can adopt Purge gas, make powder body material oxidation more all even effective;
3. adopt body of heater automatic position-adjusting device, can prevent the phenomenon of agitating vane scraping crucible, the work-ing life of improving equipment.
Accompanying drawing explanation
The structural representation of Fig. 1 embodiment of the present invention 1;
The structural representation of breather in Fig. 2 embodiment 1.
Embodiment
Below in conjunction with embodiment, the invention will be further described, but the present invention is not limited to the statement of embodiment.
Embodiment 1
For the production of an oxidized still for oxide powder material, Fig. 1 is shown in by one-piece construction schematic diagram, comprises that body of heater module 1, power stir module 2, automatic position-adjusting device module and bracing frame 3; Body of heater module 1 is conventional Proper Design, comprises shell 4, thermal insulation layer 5 and burner hearth 6, has heating unit and lagging material in thermal insulation layer 5, and body of heater top installs bell 7 additional, is mounted with crucible 8 in burner hearth 6.In body of heater four sides, spring 14 (only having shown both sides installation situation in figure) is installed, spring 14 is all connected with bracing frame 3, at bottom of furnace body, be provided with movable base 15, body of heater module whole is placed on movable base 15, and spring 14 has just formed automatic position-adjusting device module with movable base.
Power stirs module 2 and is comprised of agitating vane, stir shaft 9 and power set 10, and power set provides corresponding power for stirring, and adopts conventional mechanical to stir power set; Stir shaft 9 is quill shaft, and there is ventilating pit 16 bottom, and the part that stir shaft is equipped with agitating vane is placed in the crucible 8 in burner hearth 6, and the other end is connected with power set 10, on the top of stir shaft, breather 17 is installed, and power set 10 is installed on bracing frame 3; Mobilizable lifting rod 13 is installed on bracing frame 3, and one end of lifting rod 13 is connected with the power set 5 that stirs module; Agitating vane is installed two pairs from bottom to up along stir shaft, and one pair that is fixed on stir shaft one end at the bottom of near burner hearth is primary blades 11, and the moving vane being installed on primary blades 11 is back blades 12.
Fig. 2 is the structural representation of breather 17, installs 17 and is interconnected and formed by following parts, bearing 18, breather line web member I19, safety valve 20 and breather line web member II21.During work, air, through breather line web member I19, safety valve 20 and the breather line web member II21 of breather, is passed into crucible 8 bottoms by ventilating pit 16 in hollow stir shaft 9.
During use, can implement mechanical power simultaneously and stir when heating and thermal insulation, under primary blades 11 effects of revolving stirrer, air fully contacts with metal-powder, and back blades 12 can be by the material reverse cleaning rotating on crucible 8 walls.Owing to requiring the material on crucible 8 walls must to be removed totally at every turn, and crucible 8 at high temperature life-time service there will be certain distortion, and employing body of heater automatic position-adjusting device, body of heater automatic position-adjusting device is by spring 14 and movable pedestal 15, can automatically adjust the position of body of heater, can help material to remove the damage of simultaneously avoiding crucible and stir shaft.Practical application proves, adopts this oxidized still, can make powder body material upset more abundant, has greatly reduced the phenomenon that hardens in high-temperature oxidation process, and powder body material oxidation is more even, the more excellent performance of products obtained therefrom.
