Abstract
An assembly for sealing an electrode of a sapphire crystal furnace includes a round insulating plate (3), an O-shaped ring (4), an O-shaped ring (5) and connecting screws (8), two end faces of the round insulating plate are respectively provided with a seal groove I (14) and a seal groove II (15), the seal grooves are respectively provided with the O-shaped ring (4) and the O-shaped ring (5), the excircle sizes of the two end faces of the round insulating plate respectively coincide with a mesa II (16) of an electrode and a mesa I (10) of an electrode hole of a furnace body, a round hole (12) which is used for the electrode to be inserted into is formed along the axial center of the round insulating plate, at least three through-holes (13) which are used for connecting and fixing the electrode onto the furnace body are arranged in the radial direction of the round insulating plate, screws (8) are arranged in the through-holes in a penetrating mode, and an insulation sleeve (6) and an insulation gasket (17) are arranged on the periphery of every screw (8). The assembly for sealing the electrode of the sapphire crystal furnace has the advantages of being simple in structure, convenient to use and long in service life and not needing frequent replacement due to the fact that sealing faces are outside the furnace body to eliminate the high-temperature problem.
Description
Technical field
The utility model relates to a kind of vacuum apparatus electrode sealing, particularly a kind of assembly for the sealing of sapphire crystal stove electrode
Technical background
The sapphire crystal stove is high-vacuum apparatus, in crystal growing process, the stove internal heater is connected with the outer power supply system of stove with crossing copper electrode, for guaranteeing vacuum tightness in the stove, seal between body of heater needs and the electrode, need to guarantee to be between body of heater and the electrode state of insulation simultaneously.General electrode sealing construction adopts multiple tracks bakelite ring and rubber o-ring sealing, and this structure has following shortcoming:
At first bakelite partly is positioned at stove, ftractureed by furnace high-temperature baking easy deformation, causes sealing actual effect, needs periodic replacement; Its sub-electrode sealing is by placing sealing-ring between electrode sidewall and the electrode hole inwall, sealing-ring is realized by bakelite crimp, owing to cross and have O shape circle between electrode sidewall and the electrode hole inwall, both are Elastic Contact, can produce deformation after stressed, therefore can not fine assurance electrode and the verticality of body of heater, to such an extent as to influence the placement of interior heater.
Summary of the invention
The purpose of this utility model provides a kind of assembly for the sealing of sapphire crystal stove electrode, this unit construction is simple, easy to use, after adopting this assembly, there is not high temperature problem in trim outside body of heater, therefore long service life does not need frequent replacing, can guarantee the verticality of electrode and body of heater simultaneously.
To achieve the above object of the invention, the utility model is by the following technical solutions:
This assembly for the sealing of sapphire crystal stove electrode, it comprises circular insulating board, O shape circle, O shape circle and coupling screw, the both ends of the surface of described circular insulating board are respectively equipped with sealing groove I, sealing groove II, be respectively equipped with O shape circle 4 in the sealing groove, O shape circle 5, the excircle dimension of two end faces of described circular insulating board respectively with the table top II of electrode, the table top table top I unanimity of the electrode hole of body of heater, have the circular hole that the power supply utmost point inserts along the insulcrete axial centre, its radially have at least three be used for to connect and fixed electorde in the through hole of body of heater, be installed with screw in the through hole, the screw periphery is provided with insulation covering and insulation spacer.
The quantity of described through hole (13) is 3-6.
Described circular insulating board is rubber plate.
The utility model has the advantages that: unit construction is simple, and is easy to use, and there is not high temperature problem in trim outside body of heater, so long service life, do not need frequent replacing, can guarantee the verticality of electrode and body of heater simultaneously.
