Compared with prior art the beneficial effects of the utility model are: furnace refining getter axis system air channel air cooling mechanism of the present utility model, be mainly used in substituting and may cause the vortex tube cooling body of potential safety hazard, the main shaft of furnace refining/getter and joint member are cooled process; By being arranged on the flow-mixing blower fan of default air channel end, Cryogenic air relative for quantitative stokehold is sent in cooling body, substitute vortex tube to realize the object cooled to furnace refining getter main shaft and shaft coupling, do not need scene to provide compressed air source simultaneously, the connection of pipeline can be reduced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, furnace refining getter axis system air channel air cooling mechanism of the present utility model, comprise main shaft 10, main spindle box 11, shaft coupling 9, graphite bars 8 and air-cooled engine structure, the tail end of graphite bars is connected to the front end of main shaft by shaft coupling, the outer setting of main shaft has main spindle box, air cooling mechanism comprises blower rack 2, flow-mixing blower fan 1, reducing air channel 3, main air duct 4, primary air separating duct 6 and heat insulation 7, flow-mixing blower fan is arranged on blower rack, the inlet end of main air duct is connected with the air outlet of flow-mixing blower fan by reducing air channel, the outlet side of main air duct is communicated with on main spindle box, the front end of main spindle box connects primary air separating duct, primary air separating duct is enclosed within front-end of spindle, shaft coupling, and the outside of graphite bars tail end, the inside, front end of primary air separating duct is provided with heat insulation, the arranged outside of main air duct has the annex installing rack 5 for mounting block plate annex, main air duct and primary air separating duct are heat-resistance stainless steel material main air duct and heat-resistance stainless steel material primary air separating duct, the outside of air cooling mechanism is enclosed with temperature resistant glass fiber cloth, heat insulation is circular nano warming plate heat insulation, whole air cooling mechanism covers the coupling part of graphite bars, shaft coupling and main shaft three completely, carries out air blast cooling cooling to above position.
Concrete installation process, blower rack 2 is fixed on the bottom of main spindle box by bolt group, and main air duct 4 is fixed on main spindle box front portion by flange, and reducing air channel 3 connects flow-mixing blower fan 1 and main air duct 4 by the disk hole of upper lower flange; It is anterior that heat insulation 7 is contained in primary air separating duct 6, by Flange joint on main air duct 4; Primary air separating duct 6 covers coupling segment completely, and can freely dismantle; Air cooling mechanism outer ring parcel temperature resistant glass fiber cloth, whole air cooling mechanism follows mainshaft mechanism assembly and moves together.
It should be noted that, furnace refining getter axis system air channel air cooling mechanism of the present utility model, directly the air of much lower for atmosphere in stove relative near fire door " cold " is sent in cooling body by main air duct 4 side pipe by flow-mixing blower fan 1, air blast cooling is carried out to main shaft and coupling segment.Due to the atmosphere gas that the air sucked is near fire door, can not impact aluminum anodizing; And shaft coupling bulk temperature will far below through the temperature of graphite bars heat transfer to shaft coupling, therefore can control below 200 DEG C, to avoid shaft coupling overheated by the air themperature sucked.Main air duct 4 and primary air separating duct 6 all adopt heat-resistance stainless steel to make, and side is provided with hot anti-deformation muscle, to prevent its at high temperature excessive deformation, affect main shaft/graphite bars and rotate, and outer ring parcel temperature resistant glass fiber cloth, slows down its ablation oxidation.Annex installing rack 5 is for pacifying shield attachments, and blocking radiant heat is delivered on the mainshaft mechanism at rear portion.Stretching into completely in stove when primary air separating duct 6 works, is detachable block, directly can change spare part during serious ablation; Unloaded when changing graphite bars and exposed coupling assembly, to realize graphite bars quick-replaceable function.Heat insulation 7 circular nano warming plate is made, object stops heat in stove to be directly radiated on shaft coupling, simultaneously using the annular gap between its centre bore and graphite bars as the outlet conduits of cooling blast, cooling blast is drawn out to graphite bars surface, is decreased through the heat of the direct heat transfer of graphite bars to shaft coupling.Interval area S1 and ratio S1: the S2 < 1 of the side pipe sectional area S2 of main air duct 4, is beneficial to cooling blast and forms blast, discharge smoothly along graphite bars surface.
Furnace refining getter axis system air channel air cooling mechanism of the present utility model, it is the vitals of furnace refining getter, by being arranged on the flow-mixing blower fan of default air channel end, Cryogenic air relative for quantitative stokehold is sent in cooling body, substitute vortex tube to realize the object cooled to furnace refining getter main shaft and shaft coupling.Mechanism is as the organic component of furnace refining getter simultaneously, for operating space has been reserved in quick-replaceable graphite bars/high temperature rigid coupling assembly operation.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
