The semicontinuous dual chamber vacuum high temperature furnace of existing optical wand new technology sintering.
Background technology
With popularizing to fiber optic communication, and the enforcement of China's broadband strategy in China, the need to fiber optic materials
Ask and sharply increase, require optical fiber enterprise improve production efficiency in the world to the competition in this market again, reduce production cost, and this
A kind of bright vacuum equipment for being exactly to realize requirements above.
Content of the invention
For the present problem that optical fiber enterprises production efficiency is low, production cost is high, the present invention provides a kind of semicontinuous dual chamber
Vacuum high temperature furnace.
The semicontinuous dual chamber vacuum high temperature furnace of the present invention, being characterized by architectural feature includes that one is be furnished with air extractor, if
Get everything ready for perfect sealing structure；Two is vertical double-chamber structure, and top is that thus preparation room workpiece passes in and out, and bottom is heating chamber work
Two upper and lower chambers can be disconnected completely by part in this heat-agglomerating, middle push-pull valve；Three be third layer be actuating device；Four is workpiece
In the high purity graphite cylinder being placed in vacuum cavity.
The use technique of semicontinuous dual chamber vacuum high temperature furnace is to be first turned on passing in and out bin gate, workpiece is sent into and prepares room housing
Interior, water-cooled suspension rod is suspended to, operation adjustment door adjustment position when completing this process, need to be passed through；Two turnover bin gates and operation adjustment door
Close, start vacuum system and start aerofluxuss, monitoring vacuometer reaches setting vacuum, push-pull valve is opened, lifting motor is by workpiece
Send in the graphite-pipe of heating chamber body of heater, then under the collective effect of heating power supply, temperature measurer and control system, realize PID
Temperature control heat-agglomerating, during heating, electric rotating machine starts, workpiece rotary heating, it is ensured that workpiece in circumferencial direction thermally equivalent, radially
The multi-region independent heating in direction, independent temperature control, it is ensured that the uniformity of radial direction heating；After heating terminates, lifting motor is by work
Part is raised in preparation room housing, and push-pull valve cuts out, and workpiece is cooled to the condition of coming out of the stove, and is opened turnover bin gate, is taken out workpiece, complete one
The sintering of individual workpiece；In continuous production, heating chamber body of heater is under vacuum all the time, in hot, so both saves power consumption,
The service life of equipment is improved again, and whole process is automatically finished.
The invention has the beneficial effects as follows：Improve production efficiency, reduction production cost, had both saved power consumption, improved again and set
Standby service life, whole process are automatically finished.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
In figure：1 water-cooled suspension rod, 2 electric rotating machines, 3 lifting motors, 4 magnet fluid sealings, 5 prepare room housings, 6 turnover bin gates, 7
Operation adjustment door, 8 workpiece, 9 push-pull valves, 10 heating chamber bodies of heater, 11 heating chamber doors, 12 heating power supplies, 13,14 stone of graphite-pipe
Black felt heat-insulation layer, 15 graphite heaters, 16 vacuum systems, 17 relief valve, 18 vacuometers, 19 temperature measurers, 20 control systems.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
The semicontinuous dual chamber vacuum high temperature furnace of the present invention, architectural feature include that one is be furnished with air extractor, and equipment has possessed
Kind sealing structure；Two is vertical double-chamber structure, and top is that thus preparation room workpiece passes in and out, and bottom is that heating chamber workpiece here adds
Two upper and lower chambers can be disconnected by thermal sintering, middle push-pull valve 9 completely；Three be third layer be actuating device；Four is that workpiece is placed in very
In high purity graphite cylinder 13 in cavity body.
Innovation advantage is that the two procedures in original production technology are merged into one by the present invention, and the production time shortens one
Half, and the production consumptive material helium in new technology, chlorine etc. substantially reduces, and significantly reduces production cost.
The use technique of semicontinuous dual chamber vacuum high temperature furnace is to be first turned on passing in and out bin gate 6, and workpiece is sent into preparation room shell
In body 5, water-cooled suspension rod 1 is suspended to, 7 adjustment position of operation adjustment door when completing this process, need to be passed through；Two turnover bin gates 6 and operation
Adjustment door 7 is closed, and is started vacuum system 16 and is started aerofluxuss, and monitoring vacuometer 18 reaches setting vacuum, and push-pull valve 9 is opened, and is risen
Drop motor 3 sends into workpiece in the graphite-pipe 13 of heating chamber body of heater 10, then in heating power supply 12, temperature measurer 19 and control system
Under 20 collective effect, PID temperature control heat-agglomeratings are realized, electric rotating machine 2 starts during heating, workpiece rotary heating, it is ensured that workpiece
In circumferencial direction thermally equivalent, radial direction（That is above-below direction）Multi-region independent heating, independent temperature control, it is ensured that radial direction adds
The uniformity of heat；After heating terminates, lifting motor 3 is raised to workpiece in preparation room housing 5, and push-pull valve 9 cuts out, and workpiece is cooled to
Come out of the stove condition, open turnover bin gate 6, take out workpiece, complete the sintering of a workpiece, in continuous production, heating chamber body of heater 10
All the time it is under vacuum, in hot, so both saved power consumption, improve the service life of equipment again, whole process is full-automatic
Complete.
