Description

The long brilliant stove temperature measuring equipment of a kind of two-way type sapphire
Technical field
The utility model relates to the infrared temperature field, especially a kind of temperature measuring equipment of crucible inside temperature measurement when being applicable to sapphire crystal growth.
Background technology
What the long brilliant stove temperature measurer of sapphire of the prior art adopted is the high speed infrared temperature measurer, can catch Fast Moving Object and temperature variation fast, utilize its high-quality optical lens can clearly detect little measurement target, argon gas fed a mouthful position in the middle of pyrometer was installed on the long brilliant stove furnace chamber of heat exchange, infrared rays is through lagging material, directly measure the mode of crucible outer wall by induced radiation and obtain temperature data, control the furnace chamber temperature inside by industrial computer and change, thus the growth of control crystal.
But be arranged on the other pyrometer of sidewall of crucible and be easy to occur reading error, and after work for some time, show ultimate value because the corresponding temperature reading of its operating power of the rising of temperature can surpass.And because pyrometer is installed in the logical ingress of argon gas, furnace chamber middle part, the volatile matter of crystal is attached to lagging material work in the crystal growth because the cooling effect of argon gas causes easily, and the cooling effect meeting of argon gas causes the temperature spot place of pyrometer collection local overcooling to occur, and then causes furnace chamber temperature inside field inequality.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the applicant has designed the long brilliant stove temperature measuring equipment of a kind of two-way type sapphire through long-term practical exploration.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is: the long brilliant stove temperature measuring equipment of a kind of two-way type sapphire, comprise the thermal insulation layer of growing brilliant furnace body, being arranged on the brilliant furnace body inwall of described length, described thermal insulation layer is provided with argon gas and feeds mouth, the brilliant furnace body inner chamber of described length is provided with infrared rays survey pyrometer A near the position that argon gas feeds mouth, the brilliant furnace body of described length top arranges the pyrometer support, and infrared rays survey pyrometer B and Continental Europe table temperature regulator is set on the described pyrometer support.Utilize infrared rays survey pyrometer A and infrared rays survey pyrometer B to cooperatively interact and carry out reading, before high temperature crystal in long brilliant stove is not stopped up the pyrometer hole, the read-around ratio of infrared rays survey pyrometer A is more accurate, compares the correction data error with the reading of infrared rays survey pyrometer B.In the rising because of temperature, the temperature reading of infrared rays survey pyrometer A surpasses after the readable ultimate value like this, just can control temperature field in the crucible by the reading of observation infrared rays survey pyrometer B.
The oblique side of the brilliant furnace body probe location of described length is provided with vision slit, and described infrared rays survey pyrometer B keeps certain height apart from vision slit.Be provided with the water flow pipes cooling that circulates around the described vision slit.
The apical pore of described vision slit, thermal insulation layer inclined hole and crucible cover is designed to sight alignment, and the thermometric infrared rays of described like this infrared rays survey pyrometer B passes the apical pore of vision slit, thermal insulation layer apical pore and crucible cover, through crucible inwall.
Temperature value by infrared rays survey pyrometer B detection, forward the Continental Europe table to, corresponding temperature reading can appear in Continental Europe table display instrument, change temperature measurement module over to after by artificial mode set(ting)value being arranged, described temperature measurement module adopts the RS485 communication bus, need the RS232/485 modular converter to insert the industrial computer serial ports, realize the monitoring to the crucible temperature field.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
1, the utility model utilizes the infrared rays survey pyrometer that the temperature field in the crucible is monitored, and response is rapid, and measuring accuracy is higher;
2, two-way type infrared rays survey pyrometer is adopted in the utility model utilization, the infrared rays survey pyrometer that can realize place, long brilliant stove furnace wall is normally behind the reading, utilize the infrared rays survey pyrometer on top to carry out the temperature monitoring reading, can realize the real-time monitoring to temperature field in furnace;
3, the utility model belongs to improvement embedded type device, implants this device and just can continue to produce in original infrared observation system, needn't upgrade a complete set of equipment, and cost performance is higher.
Description of drawings
Fig. 1 is the structural representation of the long brilliant stove temperature measuring equipment of a kind of two-way type sapphire of the utility model.
Fig. 2 is for offering the synoptic diagram of inclined hole on the thermal insulation layer.
Embodiment
Below by a most preferred embodiment, the technical program is elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, the long brilliant stove temperature measuring equipment of a kind of two-way type sapphire, comprise the thermal insulation layer 2 of growing brilliant furnace body 1, being arranged on brilliant furnace body 1 inwall of described length, described thermal insulation layer 2 is provided with argon gas and feeds mouth 3, brilliant furnace body 1 inner chamber of described length is provided with infrared rays survey pyrometer A4 near the position that argon gas feeds mouth 3, the brilliant furnace body of described length 1 top is provided with pyrometer support 7, and infrared rays survey pyrometer B is set on the described pyrometer support 7.The brilliant furnace body of described length 1 top is provided with vision slit 6, and described infrared rays survey pyrometer B keeps certain height apart from vision slit 6.Around described vision slit 6, be provided with water flow pipes circulation cooling.The thermometric infrared rays of described infrared rays survey pyrometer B passes inclined hole 9 on vision slit 6, the thermal insulation layer 2 and the apical pore of crucible cover 5, through crucible inwall.
