Abstract
The utility model discloses a kind of thermocouple fixed system is installed.Native system is made up of thermopair, Thermal couple casing pipe, sleeve fixing part, vertical columns and tumbler pin.Have simple in structurely, steadiness is good, installs to change conveniently, and the advantage such as thermocouple is not fragile, is applicable to method of crystal growth by crystal pulling field.
Description
Technical field
The utility model is open
oneplant method of crystal growth by crystal pulling thermopair fixed system, relate to crystalline material preparation field, particularly method of crystal growth by crystal pulling thermocouple is installed fixed system.
Background technology
The thermocouple mounting means that formulation crystal is grown conventional at present mainly contains two kinds: 1) adopt the YAG crystal growth of zirconium cup pot mode, thermopair is enclosed within two hole alundum tubes, and alundum tube rides on zirconium cup, and in dependence, stay-warm case is fixed alundum tube; 2) adopt the YVO4 crystal of zircon sand land-fill method to grow, thermopair is enclosed within two hole alundum tubes, and whole thermocouple is embedded near zirconium dioxide insulation sand crucible, fixes by the zircon sand of tamping.(referring to patent of invention: CN02104314.0) two kinds of modes respectively have relative merits: it is simple and convenient that mode one has installation, change the advantages such as quick, but in use procedure due to the impact such as vibration and upper stay-warm case cracking of coil, thermocouple easily becomes flexible, waves the phenomenon that is even shifted, and causes the inaccurate even thermocouple of thermometric to damage; Mode two thermocouple landfills are in the zircon sand compacting, thermocouple becomes flexible, waves phenomenon and substantially stopped, but thermocouple is installed fixing more loaded down with trivial details, and in crystal growing process, zircon sand is becoming more closely knit after heating and cooling repeatedly, and easily caking, while particularly climbing material phenomenon, the zircon sand of thermocouple thermometric head and caking expects to be bonded together with climbing, and easily causes thermocouple distortion even to damage.
Summary of the invention
Problem to be solved in the utility model is to ensure that thermocouple does not become flexible, waves and the phenomenon that is shifted installing and using in process, solves again in thermopair use procedure the problems such as easily damages, meets thermocouple installation simultaneously and is fixedly easy to stdn, convenience.
For addressing the above problem, the utility model is open
oneplant method of crystal growth by crystal pulling thermopair fixed system, fixed system comprises thermocouple and thermocouple fixed support.Thermocouple can be the thermocouples such as S, Type B or iridium rhodium, W-Re, and thermocouple fixed support is made up of vertical columns (1), sleeve fixing part (2), Thermal couple casing pipe (3) and tumbler pin (4) and (5) five parts of Thermal couple casing pipe retaining screw.One threaded hole of growing is arranged at vertical columns (1) bottom, and for the height of fixing whole mounting bracket and adjusting pole, column upper side has a through hole, and top has an aperture to run through side through hole, as fixed pin holes; Thermal couple casing pipe mounting block has a circular groove, installs for Thermal couple casing pipe, and tumbler pin is used for fastening to Thermal couple casing pipe mounting block (2) and vertical columns (1).
Brief description of the drawings
Fig. 1 is the utility model thermocouple fixed support component diagram
Fig. 2 is installation fixed effect figure of the present utility model
Fig. 3 is the schematic diagram that practices of the present utility model
In figure, 1, vertical columns, 2, sleeve fixing part, 3, Thermal couple casing pipe, 4, tumbler pin, 5, Thermal couple casing pipe retaining screw, 6, thermocouple.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
First vertical columns (1) is screwed in from coil fixed leg top, be adjusted to proper height, thermocouple (6) penetrates from Thermal couple casing pipe (3), then whole Thermal couple casing pipe (3) packed in the circular groove of sleeve fixing part (2), again sleeve fixing part (2) is inserted in the side through hole of vertical columns (1), the aperture at the fixed orifices of sleeve fixing part (2) and column top is adjusted to concentric, embed tumbler pin (4), after regulating thermocouple temperature measuring head and crucible suitable distance, screw Thermal couple casing pipe retaining screw (5), for the purpose of safe, with electric tape, Thermal couple casing pipe (3) and sleeve fixing part (2) are wound around to several circles again, finally thermocouple positive and negative electrode wire is connected with the thermocouple compensating lead wire in stove, complete thermocouple fixation procedure is installed.As shown in Figure 3.In the time of the upper stove of crystal growth or lower stove, only need be by vertical columns (1) rotation one angle, thermocouple mounting bracket can integral-rotation, very convenient.And need to change when thermocouple, only Thermal couple casing pipe need be taken out, reload after penetrating new thermocouple.
Claims (1)
1.
oneplant method of crystal growth by crystal pulling thermopair fixed system, comprise temperature-measuring heat couple and thermocouple fixed support, thermocouple fixed support is made up of vertical columns (1), Thermal couple casing pipe (2), sleeve fixing part (3), tumbler pin (4) and Thermal couple casing pipe retaining screw (5) five parts, it is characterized in that: a threaded hole of growing is arranged at described vertical columns (1) bottom, for the height of fixing whole mounting bracket and adjusting pole, column upper side has a through hole, top has an aperture to run through side through hole, as fixed pin holes; Thermal couple casing pipe mounting block has a circular groove, installs for Thermal couple casing pipe, and tumbler pin is used for fastening to Thermal couple casing pipe mounting block (2) and vertical columns (1).
