Abstract
The invention discloses a foot pad for a heating body support foot. The foot pad has the advantages that the heat insulation performance is good, and the installation and the regulation are convenient. The foot pad comprises a support foot (1), a positioning support seat and a positioning insulation body, wherein the support foot (1) is provided with a positioning pin hole (2) in the axial direction, and the positioning support seat is positioned by the positioning pin hole (2). The foot pad is characterized in that the positioning support seat is processed and manufactured by carbon/carbon composite materials. The foot pad has the advantages that the heat insulation performance is better, the heat loss is small, the energy sources are saved, the production cost is reduced, in addition, the intensity is high, the height is easy to regulate, and the installation and the use are convenient.
Description
Technical field
The present invention relates to a kind of single crystal growing furnace, specifically relate to a kind of heater of single crystal growing furnace, particularly relate to a kind of foot pad of heater feet.
Background technology
Single crystal growing furnace is the capital equipment that semiconductor and solar photovoltaic industry are generally applied, and its maximum operation (service) temperature is up to more than 1600 DEG C.At present, often adopt resistance heating manner, its heater generally adopts high-purity special graphite or carbon/carbon compound material preparation.Heater is all provided with four connecting pins usually, is uniformly distributed at heater circumferencial direction, and two relative pin partner, and all has support and/or conducting function.During installation, only need a pair pin wherein to connect with the graphite electrode in stove and make work pin, this graphite electrode is connected with the copper electrode outside stove, the electric current that copper electrode stream comes is passed to heater, heater is generated heat, for the fusing of silicon material and crystal growth provide heat; Another is to making feet, be supported on comprise positioning support, locating insulator foot pad on, when at high temperature working for a long time to prevent heater occur creep.
Because positioning support adopts graphite material to make, and the thermal conductivity of graphite material is good, poor thermal insulation property, and the heat that heater produces can pass to outside stove from here, causes energy waste, increases production cost.In addition, feet, positioning support, locating insulator are stacked together one by one, and the adjustment of its height comparatively bothers, and during installation, the work of finding accurately of horizontal level is also more difficult.
Carbon/carbon compound material is a kind of net tire of being made by carbon fiber and net tire, or carbon cloth and carbon cloth, or net tire and carbon cloth compound, again through density, the carbon/carbon compound material of carbonization and graphitization processing, there is high specific strength, high ratio modulus, high temperature resistant, resistance to ablation, thermal coefficient of expansion is little, resistance to rapid heat cycle and indeformablely do not ftracture and have the premium properties such as heat insulating ability concurrently, be adapted to high-temperature field especially, now become or progressively will become Aero-Space, metallurgical, one of the important foundation material in the fields such as new forms of energy, it is the ideal substitute of graphite product and high temperature steel.
Summary of the invention
The object of this invention is to provide a kind of good heat insulating, the foot pad of installation, heater feet easy to adjust.
The present invention adopts following technical scheme to realize its goal of the invention, a kind of foot pad of heater feet, it comprises axis and offers the feet of dowel hole, the positioning support of being located by dowel hole, locating insulator, and described positioning support is processed into by carbon/carbon compound material.
The present invention is for the ease of regulating height, described positioning support comprise located by dowel hole support bar, be located at supporting disk above locating insulator, support bar one end is provided with screw rod, and support bar to be threaded with supporting disk by screw rod and to be fastened on supporting disk by fastening screw nut.
The present invention is in order to install steadily, and described locating insulator is the insulating cylinder of tubular, is connected between supporting disk with insulating cylinder with ledge structure.
The present invention is for the ease of installing, and the barrel of described insulating cylinder is provided with the groove being parallel to its center line, and groove width is greater than the diameter of screw rod.
The present invention is in order to energy-saving safe, and described insulating cylinder adopts ceramic material to make.
Owing to adopting technique scheme, the present invention achieves goal of the invention preferably, and its heat-insulating property is better, and thermal losses is few, saved the energy, reduced production cost, and intensity is high, is highly easy to regulate, easy to install.
