Description
Technical field
The utility model belongs to machining graphite field, more particularly to a kind of to prevent graphite-pipe to be tightly connected by thermal destruction
Component.
Background technology
The purifying of graphite material is that graphite product is put into the crucible of graphite furnace, by graphite crucible be warming up to 1800 DEG C with
Chlorine is passed through after upper, by becoming at high temperature after the metal in chlorine and graphite, nonmetallic ion impurity reaction generation chloride
Taken out of into gas.
Graphite furnace is provided with the graphite-pipe of ventilation, graphite-pipe one end access body of heater, one end connection air feed equipment.Existing skill
Art connects the connection component of air feed equipment and graphite-pipe（Shown in accompanying drawing 1）Usually a metallic sleeve gasket headgear is on graphite-pipe,
Sealing gasket is lined between sealing pullover and graphite-pipe to stop that gas is leaked.When graphite furnace is heated to thousands of spend, graphite-pipe is heated
It can expand and transfer heat to connector position, metal pullover has the temperature difference with graphite-pipe junction, it is easy to cause graphite-pipe fracture leakage
Hazardous gas, security risk is big.
Utility model content
The purpose of this utility model is：To overcome the shortcomings of the existing technology, the utility model, which provides one kind, prevents graphite-pipe
By the sealing connecting component of thermal destruction.
To achieve the above object, the technical solution of the utility model is：
A kind of sealing connecting component for preventing graphite-pipe by thermal destruction, including ventilation graphite-pipe, sealing gasket, connector, lead to
Gas graphite-pipe one end is connected with connector, and ventilation graphite-pipe is lined with connector junction prevents the sealing gasket of gas overflowing, institute
State ventilation graphite-pipe and neck is provided with the tube wall of connector one end, the connector is provided with the first connection sheet and the second connection
Piece, the first connection sheet is placed in ventilation graphite-pipe one end, and second connection sheet one end is inserted in neck, pull bar through the first connection sheet and
The two is connected and locked with fixture by the second connection sheet, and buffer spring, buffering elastic are provided between the second connection sheet and fixture
Spring is enclosed on pull bar, and the trachea for being used for conveying gas is provided with the middle part of first connection sheet.
Further, the neck number is 3~8, is uniformly arranged in tube wall one week.
Further, the internal diameter of the trachea is identical with the internal diameter for graphite-pipe of ventilating.
Further, the fixture is nut.
As a result of such scheme, the beneficial effects of the utility model are：The utility model is simple in construction, sets slow
Spring is rushed, is that graphite expands with heat and contract with cold offer pulling force buffering, the problem of connector is with ventilation graphite-pipe junction easy fracture is solved,
Production efficiency is improved, it is cost-effective；Good seal performance, prevents gas leakage, it is ensured that the security of production line；Connector and ventilation
Graphite-pipe contact area is small, rapid heat dissipation, further prevents the ventilation graphite-pipe contact surface temperature difference and causes fracture.
Brief description of the drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Reference：1- ventilation graphite-pipes, 11- necks, 2- sealing gaskets, 3- connectors, the connection sheets of 31- first, 32- second
Connection sheet, 33- tracheas, 34- buffer springs, 35- fixtures, 36- pull bars.
Embodiment
Embodiment：With reference to Fig. 2, a kind of sealing connecting component for preventing graphite-pipe by thermal destruction, including ventilation graphite-pipe 1,
Sealing gasket 2, connector 3, ventilation one end of graphite-pipe 1 are connected with connector 3, and ventilation graphite-pipe 1 is lined with anti-with the junction of connector 3
The only sealing gasket 2 of gas overflowing, the ventilation graphite-pipe 1 is provided with neck 11, the connection on the tube wall of the one end of connector 3
First 3 are provided with the first connection sheet 31 and the second connection sheet 32, and the first connection sheet 31 is placed in ventilation graphite-pipe 1 one end, the second connection sheet
32 one end are inserted in neck 11, and the two is connected through the first connection sheet 31 and the second connection sheet 32 and use fixture 35 by pull bar 36
Locking, is provided with buffer spring 34 between the second connection sheet 32 and fixture 35, buffer spring 34 is enclosed on pull bar 36, and described first
The middle part of connection sheet 31 is provided with the trachea 33 for being used for conveying gas.
The number of neck 11 described in the present embodiment is 3~8, is uniformly arranged in tube wall one week.
The internal diameter of trachea 33 described in the present embodiment is identical with the internal diameter for graphite-pipe 1 of ventilating.
Fixture 35 described in the present embodiment is nut.
During work, gas is passed through in graphite furnace by the connection air feed equipment of trachea 33, air feed equipment ventilation graphite-pipe 1, stone
Black stove constantly heats up, the expanded by heating of graphite-pipe 1 of ventilating, with the ventilation graphite-pipe 1 of the junction of connector 3 laterally, longitudinal direction all can be by
Thermal expansion.In transverse direction, the ventilation expansion elongation of graphite-pipe 1, the forced compression of buffer spring 34, can prevent graphite expansion unbalance stress and
Fracture；On longitudinal direction, connector 3 is not exerted a force to ventilation graphite-pipe 1, and the expanded by heating of graphite is not influenceed.Likewise, working as graphite furnace
When work finishes cooling, unbalance stress causes the situation of fracture to occur when being also possible to prevent ventilation 1 cooling meat of graphite-pipe.
