Background technique
High-purity polycrystalline silicon is the basic material of semiconductor devices such as photoelectric conversion battery, intergrated circuit.Along with the fast development of world semiconductor industry, the extensive application of very large scale integrated circuit, the wilderness demand of photovoltaic cell, All Around The World is significantly increasing the demand of polysilicon.
Hydrogenation furnace is the key equipment in the polysilicon production process, and is very high to Security and sealing requirements, and good sealing property is related with the bolt arrangement that is used for connection device flange and chassis.In addition, hydrogenation furnace needs regular blowing out maintaining in process of production, and the bolt arrangement that is used for connection device flange and chassis will be a purpose with the conveniently fast disassembling connection.And present most of hydrogenation furnace employings is the quick open type bolt arrangement, though it is more convenient that this bolt arrangement is dismantled, but pad impacting force between vessel flange and the chassis and action center circular diameter increase, therefore required bolt pretightening and minimum bolt area increase, flange thickness increases, and diameter increases.
The model utility content
The purpose of this utility model is to provide a kind of hydrogenation furnace that can satisfy various models, and connection for convenience detach, and the pad impacting force is little, little, the thin thickness of flange diameter, the swing bolt structure of the requirement that required bolt pretightening and minimum bolt area are little.
Novel hydrogenated stove swing bolt structure in the utility model, be used to seal the vessel flange and the chassis of the hydrogenation furnace of the various models of tight connection, described swing bolt structure includes bearing, swing bolt, packing ring, nut, gusset, the chassis of wherein said hydrogenation furnace and vessel flange are evenly equipped with several orientation, U-groove bevel that quantity is consistent in order to cooperate described swing bolt structure at outer side wall;
Described bearing welding is connected in the lower surface on described chassis, the lower surface of the described U-groove bevel corresponding position of offering on described chassis simultaneously, the sidewall of described bearing are welded with two relative gussets, and on these two relative gussets, have coaxial through hole, that end in described swing bolt strap bolt hole is put between described two gussets and is connected with described gusset by link, and can be around described link upset;
Described packing ring and described nut described swing bolt be used to be sealedly connected and fixed described vessel flange during with the chassis end opposite with described swing bolt strap bolt hole be connected and fixed.
Described link is to penetrate bolt behind the bolt hole of the through hole of described gusset and described swing bolt and the coupling nut that is used to tighten, and the through hole of described gusset is a bolt hole.
The centre of described chassis and vessel flange is provided with the pad of sealing usefulness.
The outward edge of described vessel flange is processed with the annular small boss that can prevent that described swing bolt from skidding off because of the micro-deformation behind the vessel flange pretension.
Novel hydrogenated stove in the utility model can be dismantled connection very easily with the swing bolt structure, and is fastening effective.
Description of drawings
Fig. 1 is to be the cross-sectional schematic that hydrogenation furnace is used the swing bolt structure in the utility model;
Fig. 2 is the schematic side view of the lower half portion of swing bolt structure shown in Fig. 1;
Fig. 3 is the schematic top plan view of swing bolt structure shown in Fig. 1.
Among the figure:
1 bearing, 2 swing bolts, 3 chassis, 4 vessel flanges
5 packing rings, 6 nuts, 7 gussets, 8 bolts
9 coupling nuts, 10 pad 11U shape grooves, 12 annular small boss
Embodiment
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, hydrogenation furnace is used to seal the vessel flange 4 and chassis 3 of the hydrogenation furnace of the various models of tight connection in the utility model with the swing bolt structure, be that vessel flange 4 connects by the swing bolt structure with chassis 3, and at vessel flange 4 and the chassis 3 middle pads 10 that are used to seal that are provided with.
Swing bolt structure in the utility model includes bearing 1, swing bolt 2, and packing ring 5, nut 6, gusset 7, bolt 8, coupling nut 9, wherein:
The chassis 3 of hydrogenation furnace and vessel flange 4 are evenly equipped with the U-groove bevel 11 of several orientation, quantity unanimity in order to cooperate the setting of swing bolt structure at outer side wall.And between the outward edge of vessel flange 4, per two U-groove bevels 11, be processed with annular small boss 12, be used to prevent swing bolt 2 and skid off, as shown in Figure 3 because of the micro-deformation behind vessel flange 4 pretensions.
The installation process of swing bolt structure is as follows in the utility model:
Quantity and U-groove bevel 11 consistent swing bolts 2 are put into corresponding U-groove bevel 11, wherein the size of the fluting of U-groove bevel 11 is bigger slightly than the diameter of swing bolt 2, that end in swing bolt 2 strap bolt holes is put between two gussets 7, penetrate the bolt hole of gusset 7 and swing bolt 2 with bolt 8, and tighten with coupling nut 9, one end of swing bolt 2 just can be overturn around bolt 8, wherein bolt 8 can be by other links with coupling nut 9, substitute as polished rod, pin etc., as long as can make swing bolt 2 make rotary movement.So assembling finishes.
Before equipment operation, swing bolt 2 around upwards upset of bolt 8, is snapped in the U type groove 11, on swing bolt 2, be inserted in packing ring 5, be stuck in the annular small boss 12 of vessel flange 4 fastening nut 6.
When the blowing out cleaning needs dismounting swing bolt 2, unclamp nut 6, swing bolt 2 upsets are put down, whole unloading process is simple and convenient.
In sum, swing bolt structure in the utility model links up swing bolt 2 and gusset 7 by bolt 8, make that swing bolt 2 can be around bolt 8 rotations, connection for convenience detach, gusset 7 not only can play reinforing function to bearing 1 simultaneously, and, can bear bigger tensile stress by being welded on the chassis 3.
In addition, by between chassis 3 and vessel flange 4, pad 10 being set, and, not only can make swing bolt 2 more close pads 10, pad impacting force action center circular diameter is reduced by opening U type groove 11, and connection for convenience detach.Simultaneously, the external diameter of chassis 3, vessel flange 4 is corresponding can be reduced, and thickness can attenuate, saves material.
