Technical field
The utility model belongs to single crystal furnace equipment technical field, especially relates to a kind of mono-crystal furnace cover with viewing window.
Background technology
The bell of traditional single crystal growing furnace is generally all provided with viewing window, but viewing window is all fixed together with bell, the growing state of the monocrystalline in single crystal growing furnace cannot be observed in all directions, if corresponding parameter cannot be adjusted in time for observation situation, the quality of production of crystal will be affected.Therefore, the generation situation that a kind of monocrystalline can comprehensively observed in single crystal growing furnace is complete is needed.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of mono-crystal furnace cover with viewing window, clearly can observe furnace interior crystal and generate situation, quality of finished product good.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of mono-crystal furnace cover with viewing window, comprises symmetrically arranged hanger on lid, shield cap, observing device and lid; Described shield cap comprises the retaining plate of the threaded connecting hole in middle part and transparent cylindric cover body; The corresponding threaded connection hole in one end of described cover body opening is connected on retaining plate, and the other end is passed down through lid; Described retaining plate is dismountable to be arranged on lid; Described observing device comprises adjustable lens barrel, the viewing window of adjustable lens barrel upper end and the eyeglass of adjustable lens barrel lower end; What described adjustable lens barrel was vertical is threaded on retaining plate, and its one end being provided with eyeglass is stretched in cover body through retaining plate; On described adjustable lens barrel, the position be in above retaining plate is provided with stop block; Gasket is provided with between described retaining plate and lid.
Further, described lid lower end is spherical concave surface.
Further, described lid lower surface there is heat-reflecting layer.
Further, described lid is also provided with test port.
Further, described adjustable lens barrel is telescopic structure.
Further, full-view camera is provided with in described adjustable lens barrel.
Further, described eyeglass with respect to the horizontal plane has the inclination angle of 15 ° ~ 20 °.
Further, described lid lower end is provided with the boss engaged with body of heater.
The advantage that the utility model has and positively effect are:
1) viewing window is set on the lid of single crystal growing furnace, clearly can observes crystal and generate situation, be conducive to operator and gather and adjustment relevant parameter.
2) observing device is installed on the shield cap on lid, due to good airproof performance between shield cap and lid, structure and the resistance to air loss of mono-crystal furnace cover therefore can not be destroyed, and shield cap energy full protection eyeglass, make observing device longer service life, vulnerable to pollution observing effect is not better for eyeglass.
3) shield cap is dismountablely installed on lid, can disassemble cleaning easily or change when cover body is polluted or damage.
4) what adjustable lens barrel rotated is connected on shield cap, again because eyeglass has certain inclination angle, therefore, can by rotating lens barrel, make eyeglass aim at different position in stove to observe, visible angle improves greatly, and stop block can prevent lens barrel from adjusting excessively and answering back to shield cap downwards.

Embodiment
It should be noted that, in not afoul situation, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
With a mono-crystal furnace cover for viewing window, as shown in Figure 1, symmetrically arranged hanger 3 on lid 1, shield cap 2, observing device and lid 1 is comprised; As shown in Figure 4, described shield cap 2 comprise middle part threaded connecting hole 13 determine plate 4 and transparent cylindric cover body 5; As shown in Figures 2 and 3, the corresponding threaded connection hole 13 in one end of described cover body 5 opening is on retaining plate 4, and the other end is passed down through lid 1; Described retaining plate 4 is dismountable to be arranged on lid 1; Described observing device comprises adjustable lens barrel 6, the viewing window 7 of adjustable lens barrel 6 upper end and the eyeglass 8 of adjustable lens barrel 6 lower end; What described adjustable lens barrel 6 was vertical is threaded on retaining plate 4, and its one end being provided with eyeglass 8 is stretched in cover body 5 through retaining plate 4; On described adjustable lens barrel 6, the position be in above retaining plate 4 is provided with stop block 9; Gasket 10 is provided with between described retaining plate 4 and lid 1.
It should be noted that, observing device is installed on the shield cap 2 on lid 1, due to good airproof performance between shield cap 2 and lid 1, therefore structure and the resistance to air loss of mono-crystal furnace cover can not be destroyed, and shield cap 2 energy full protection eyeglass 8, make observing device longer service life, vulnerable to pollution observing effect is not better for eyeglass 8.
