It is equally spaced, the so convenient thermally equivalent in larger space improves thermal efficiency.In order to be supervised in real time to temperature everywhere
Survey, can be provided with multiple thermocouple temperature control points 10 in body of heater 1, thermocouple temperature control point 10 alternatively up and down, be equally spaced, utilize heat
Galvanic couple detects and controls the current interruptions of heater circuit by control system to realize heating or be incubated.Due to heating tube simultaneously
Connection, with certain independence, and thermocouple temperature control point mount point is corresponding with heating tube position, and so when somewhere, temperature exists
When outside specified for temperature ranges, Partial controll can be achieved, it is to avoid hot-spot.
The automatic locking mechanism 3 includes the multiple fire resisting doors 4 for being arranged on the side of heating furnace body 1, and fire resisting door 4 is using Ni-based
Alloy material is made.Nickel-bass alloy material belongs to exotic material, it is ensured that using permanent.Fire resisting door 4 is by slide bar 11 along heating
Body of heater 1 is slided up and down, and the bottom of slide bar 11 and the bottom of heating furnace body 1 are mounted on pulley 12, and steel wire rope 13 bypasses pulley 12 and wound
On hook base 14, pulley not only has draw, while can also make steel wire rope away from high-temperature furnace body, it is to avoid high temperature influences.
Hook base 14 is slidably arranged on slide rail and driven by cylinder 5.And the upper end of hook base 14 is provided with splicing bar 6, cylinder 5 is forward
Drive hook base 14 when, splicing bar 6 is gradually forward extended out, when fire resisting door 4 is slipped down to it is a certain external when, the termination of splicing bar 6 is just
Stretch out material mouth.During work, the piston rod of switch board control cylinder is released, and steel wire rope is moved forward in roller, because slide bar loses
Lineoutofservice signal pull is gone to act on, it is automatic under gravity to glide, open softening furnace.The structure has some benefit：1）, the structure exists
Outside, each mechanism avoids being influenceed by high temperature, increases the service life, and reduces and changes number of times；2）, fire resisting door, the drive of splicing bar
Dynamic is linkage, and whole action is uniformly coordinated, relative to original independent enabling, for splicing bar rises, simplifies action,
Reduce because control program is excessive and caused by more errors possibility；3）, need only to rope traction, and in outside, not only
Operable automatically, when power down mode can be also operated manually.4）, when cylinder release drive fire resisting door glide material mouth is opened
When, bracket is released simultaneously, is that blowing is prepared, and can so ensure that blowing is continuously quickly carried out, it is to avoid the heat in high temperature furnace dissipates
Lose, impacted while reducing heat bridges to the working environment of workers（Summer temperature is too high）.
Set resistance in addition, body of heater 1 is set on rectangle, body of heater 1 equidistantly be provided with multiple material mouths, material mouth along its length
Vent, fire resisting door is provided opposite to splicing bar.When cylinder 5 advances, fire resisting door is moved down under gravity, and splicing bar is stretched simultaneously
Go out, glass object is put into, cylinder is returned, carry out multigroup operation.Due to that can be operated apart from speed etc. by control system to air valve
To realize, so condition can be provided for batch-automated operation.
The heating furnace body 1 includes metal shell body 7, heat-insulation layer 8 and flame retardant coating 9, and wherein heat-insulation layer 8 uses asbestos material
Make, flame retardant coating 9 is made of the refractory brick of silicon carbide material.It is acidproof because the refractory brick of silicon carbide material has alkali resistance
Property, thermal shock resistance, thermal coefficient of expansion is small, and the advantages of thermal conductivity is good, highest is resistant to 1650 degree of high temperature.So, can effectively it change
Kind device needs the adaptability of hot conditions to glass manufacture, also makes full use of complementary energy and waste heat, has reached resource secondary utilization
Effect.
Hollow cavity is set in the splicing bar 6, cavity termination connects with cooling water pipe 15, collectively forms circulating cooling pipe
Road.Thereby guarantee that in high temperature furnace, the temperature of splicing bar 1 will not also be raised to very high, exist for a long time this avoid splicing bar
High temperature is more than deformation under 1000 degrees celsius, oxidation.
The splicing bar 6 includes front end splicing portion 6-1, stage casing refractory sections 6-2 and rear connecting portion 6-3, wherein, preceding termination
Material portion 6-1 opens, and is formed on support mouth, the support mouth and is evenly distributed with multiple limited impressions, the limited impression can limit original state
Parison is slided, it is ensured that turnover is steady.Because parison upper end size is big, lower end size is small, by asking mouth to enter
Row excellent support, spacing, support mouth and the charging aperture on softening furnace are just right.High temperature resistant graphite cannula is cased with outside the refractory sections 6-2 of stage casing, by
This can ensure the supporting part overall performance of splicing bar, it is to avoid because length is long and local deformation, improve intensity.Rear connecting portion 6-
3 are connected with cylinder 5, put in stretching by cylinder 5.
The rear connecting portion 6-3 is by connecting seat and the bolt connection of hook base 14, and connecting seat includes train wheel bridge 6-4 with
Clamping plate 6-5, train wheel bridge 6-4 and lower plate 6-5 one end are hinged, the other end is locked in pin-and-hole 6-6 by bayonet lock, and splicing
Bar 6 is then arranged in mounting groove 6-7；Connect for convenience, in lower plate 6-5, bottom is provided with the L-type connecting seat of specular, L
Type connecting seat 6-8 can facilitate the locking of two ends slot milling progress lower members.
Further, since the heating wire heat resistance inside traditional U-shaped heating tube is relatively low, in the stove more than 1000 degrees Celsius
Damage soon in vivo and bending section is easily rupturable.Find that Cr-Al alloy heating wire maximum operating temperature can reach by test of many times
1400 degrees Celsius, thermal conductivity factor is 60.3KJ/m.h DEG C, and resistivity is 1.09+0.05 μ Ω m, with the heating wire of such a material
Replace the heating wire of softening furnace in itself and can adapt to glass lens production, service life is long, and surface recombination is high, and have preferably anti-
Oxidisability.In addition, in order to avoid bending part is broken, the straight sections pipe thickness of U-shaped heating tube is less than bent portion thickness.
