In figure: the high-temperature vacuum sintering furnace 10, body of heater 20, thermal insulation layer 30, heater 40, heat shielding 50, heat shielding plate 501, heat shielding positioner 502, spacer ring 5021, positioning screw 5022, the silk braid 5023 that adopt heat shielding positioner.
Detailed description of the invention
With reference to figure 1 to Fig. 4, a kind of high-temperature vacuum sintering furnace 10 adopting heat shielding positioner, comprise body of heater 20, thermal insulation layer 30, heater 40 and heat shielding 50, body of heater 20 is cylinder, heater 40 is arranged at furnace interior around body of heater 20 sidewall, thermal insulation layer 30 is between sidewall of the furnace body and heater 40, heat shielding 50 is two groups, be arranged at furnace interior top and bottom respectively, heat shielding 50 comprises heat shielding plate 501, heat shielding positioner 502, heat shielding plate 501 is connected with body of heater 20 top and bottom by heat shielding positioner 502, heat shielding positioner 502 comprises spacer ring 5021, positioning screw 5022 and silk braid 5023, the metallic plate that heat shielding plate 501 stacks for stratiform, spacer ring 5021 is set between neighbouring metallic plate, so that adjacent metallic plate is separated, reserved positioning screw hole on each metallic plate, and the positioning screw hole on adjacent metallic plate faces, positioning screw 5022 assembles described silk braid 5023 through two ends after the positioning screw hole on metallic plate, so that metallic plate is compressed, reserved at least four positioning screw holes on each metallic plate, the quantity of positioning screw 5022 is consistent with positioning screw hole quantity, positioning screw arranges at least four, can be four, the six roots of sensation, positioning screw hole is evenly distributed on heat shielding plate disc, corresponding positioning screw 5022 is also uniformly across on heat shielding plate 501 disc, guarantee positioning screw 5022 uniform force dispersion on heat shielding plate 501, positioning screw also passes spacer ring 5021 and contacts with spacer ring 5021, so locate spacer ring 5021, guarantee that spacer ring can not loosen in the horizontal direction or slide, spacer ring 5021 is elastic metallic ring, the upper and lower end face of spacer ring 5021 is plane, see Fig. 4, it is plane contact when contacting with metallic plate, compared to the scheme using spring head and the tail connected mode space between adjacent metallic plate, contact surface is smooth stable, there is not the problem loosening or slide, at two end configuration silk braids 5023 or the nut of positioning screw 5022, heat shielding plate is compressed by fastening silk braid 5023 or nut, when screwing silk braid 5023, silk braid slowly contacts when contacting the end face of heat shielding plate, and be face contact, because heat shielding plate is very thin metallic plate, in hot environment, fragility is very large, the contact surface of such expansion silk braid and heat shielding plate is just not easy to destroy heat shielding plate.
