Description
Technical field
The present invention relates to the heating and thermal insulation component technology of sapphire single-crystal furnace thermal field stove, be specifically related to a kind of multilayered structure molybdenum heat screen.
Background technology
Thermoscreen is the important insulation construction of sapphire single-crystal furnace, its Main Function be ensure burner hearth thermal field temperature homogeneity and improve heat utilization rate.Thermoscreen is generally divided into side thermoscreen and upper and lower thermoscreen.Because the temperature of thermal field of sapphire single-crystal bulk-growth is more than 2000 DEG C, under such environment for use, to the resistance toheat of thermoscreen and intensity, there is higher requirement.In existing technology, because each individual layer thermoscreen heating temperature from inside to outside after heating element heats is higher, because thermoscreen self expands with heat and contract with cold and the unequal condition of internal stress, thermoscreen is caused to deform, thus make warm field uneven, substantially reduce the work-ing life of thermoscreen.Virtually improve cost of manufacture, equally also govern the development and progress of China's sapphire single-crystal furnace apparatus.
Utility model content
The purpose of this utility model is the single molybdenum disk problem on deformation of the thermoscreen for the multilayered structure existed in prior art, a kind of multilayered structure molybdenum heat screen is provided, comprise multiple single molybdenum disk, each single molybdenum disk is provided with through hole, each single molybdenum disk is provided with the protruding rail supporting each adjacent monolayer Mo wafer, is installed with two ends in through hole and is provided with fastening support molybdenum screw rod.
Preferably, described in the through hole be arranged on single molybdenum disk have several, each through hole two ends close position is respectively provided with one protruding rail, described protruding rail is used for supporting and fixing adjacent Mo wafer, wherein, protruding rail place is pressed into semicircle, makes also to leave gap between adjacent Mo wafer;
Preferably, being arranged to quarter bend below described molybdenum screw rod curved, and leaving one section of supported molybdenum screw rod, for forming molybdenum heat screen bottom support frame, above screw rod, being provided with fitting nut;
Preferably, described supported molybdenum screw rod is outside equipped with molybdenum screw support cover;
Preferably, described single molybdenum disk to comprise on individual layer Mo wafer under Mo wafer and individual layer;
Preferably, under described individual layer, the quantity of Mo wafer is 8-12;
Preferably, described each single molybdenum disk is coaxial cylindrical;
Preferably, described supported molybdenum screw rod quantity is 8.
The beneficial effects of the utility model are:
1, because technology provides a kind of multilayered structure molybdenum heat screen, each single molybdenum disk supports the structure be connected together mutually, can not produce distortion after making to be heated.
2, each single molybdenum disk is provided with organizes protruding rail more, each protruding rail protruding rail place is pressed into semicircle, make also to leave gap between adjacent Mo wafer, when can make to heat, heat both can outwards flow out, and decreased the distortion because internal/external heating inequality causes heat insulation bottle to produce.
Accompanying drawing explanation
Fig. 1 be the utility model patent look squarely sectional view.
Embodiment
Below in conjunction with Figure of description, the utility model preferred embodiment is described, a kind of multilayered structure molybdenum heat screen that the utility model provides looks squarely sectional view as shown in Figure 1, this thermoscreen comprises multiple single molybdenum disk 11, each single molybdenum disk 11 is provided with through hole, each single molybdenum disk 11 is provided with the protruding rail 15 supporting each adjacent monolayer Mo wafer 11, is installed with two ends in through hole and is provided with fastening support molybdenum screw rod 12.Wherein, each through hole two ends close position is respectively provided with one protruding rail 15, for supporting and fixing adjacent single molybdenum disk 11, wherein, protruding rail 15 place is pressed into semicircle 16, makes also to leave gap 19 between adjacent monolayer Mo wafer 11, quarter bend tune 17 is arranged to below supported molybdenum screw rod 12, and leave one section, for forming molybdenum heat screen bottom support frame 18, above supported molybdenum screw rod, be provided with fitting nut 14.During concrete enforcement, each single molybdenum disk 11 is first through machinery and mould compacting, and make it form the semicircle protruding rail 15 of desired number according to actual needs, each single molybdenum disk 11 stacks up along semicircle protruding rail about 15, like this, lower support form gap 19 on each adjacent monolayer Mo wafer 11.Supported molybdenum screw rod 12 have quarter bend curved one is as bottom, one with molybdenum nut 14 is passed from the through hole of each single molybdenum disk 11 stacked up, especially, according to actual needs, molybdenum screw rod 12 bottom right angle stays one section outside knee, for supporting each single molybdenum disk 11; Molybdenum screw rod 12 is by outer field molybdenum screw support cover 13, and molybdenum screw support cover 13 can fastening each single molybdenum disk 11, and protects molybdenum screw rod 12.One with molybdenum nut 14 is passed through fastening nuts.In whole process, optimum, supported molybdenum screw rod 12 is outside equipped with Mo wafer support set 13; Single molybdenum disk 11 to comprise on individual layer Mo wafer under Mo wafer and individual layer; Under individual layer, the quantity of Mo wafer is 8-12; Each single molybdenum disk is coaxial cylindrical; Supported molybdenum screw rod quantity is 8.
It is last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model but not to be limited, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical solution of the utility model or equivalent replacement, and these are revised or be equal to the spirit and scope that replacement also can not make amended technical scheme disengaging technical solutions of the utility model.
