Specific embodiment
With reference to the accompanying drawing, the present invention is described in more detail.
A kind of top heating device of platinum channel stirred tank provided by the invention is by improving stirred tank apex cavity
Environment temperature inhibits the condensation of platinum rhodium metal volatile matter, and by moving up to cooling coagulation region, makes it fixed
Region condensation accumulation, and the design to structure herein can periodically replace the brick of coagulation accumulation, reduce coagulation
A possibility that falling.
Since during the manufacturing of base plate glass, the melting defect of high-temperature area is that influence is undesirable main at present
Problem, and the defect of platinum rhodium accounts for major portion in melting defect.It therefore, is current production process to the reduction of platinum rhodium defect
In big event.Since platinum channel uses platinum-rhodium alloy material, compared to corrosion resistance resistant to high temperatures for other materials
It is excellent, but nonetheless, producing line long lasting for using, material itself is also faced with huge test.At 1600 DEG C or more
Environment in, platinum-rhodium alloy can also generate volatilization with oxidation process, in air be mainly respective oxide form,
When encountering the lower region of temperature, simple substance will be dissociated into again and be attached to interface zone, and can be tired with the time
Product, coagulation also increase and expand continuous, these coagulations show different similar " rock sugar " under an optical microscope
Structure it is polyhedron-shaped.When the amount of coagulation accumulation reaches a certain level, it just will appear falling for randomness, and these
When grain is fallen into the glass metal in stirred tank, so-called " flash-point " just will form.The particulate matter of these platinum rhodiums can be with stirring
The effect mixed, is partially dissolved in high-temperature glass liquid, and the platinum rhodium concentration in glass metal is made to become larger.At present by periodically in glass
Platinum rhodium element content be measured, come understand they concentration variation.
These glass metals for containing a certain concentration platinum rhodium continue to flow backward with platinum channel, and gradually with temperature
It reduces, finally is precipitated to form tens the even metal defect of several hundred a micron levels in the region that condition meets, and these are lacked
It falls into once being greater than 100um, product will be caused bad.Due to this unmodifiable fault of construction there is agitating device, stir
Mixing groove top portion will necessarily be there is open area, and current soluble scheme is exactly by lifting agitation tank apex cavity
Temperature avoids condensing it in cavity inside, and top exit region will be moved on coagulation region, and design in this region
Replaceable structure achievees the purpose that periodic cleaning.
As shown in Figure 1 and Figure 2, the top heating device of a kind of platinum channel stirred tank provided by the invention, including be mounted on
The top heating device ontology in platinum channel stirred tank top exit region, the top heating device ontology includes sector structure
Side insulating brick 4 and sector structure side wire vent insulating brick 6.The side insulating brick 4 is provided with eight, and side wire vent is protected
There are two the warm settings of brick 6, side wire vent insulating brick 6 and the circumferentially disposed formation cylindrical structure of side insulating brick 4, together
When, in 180 ° of arrangements between two side wire vent insulating bricks 6, guarantee that the heater strip on both sides can be drawn.
The axial cross section of side insulating brick 4 and side wire vent insulating brick 6 is the L-type structure of horizontal inversion, cylindrical body knot
Structure is centrally formed with stepped cavity, and the big end of the stepped cavity is cavity area 9, the region belong to one it is relatively closed
Heating space, by the lasting heating of heating rod, make the heat of its cavity to the inside of stirred tank top heater transmit, it is auxiliary
Help top heater that the region inside stirring groove top is heated and kept the temperature jointly, to guarantee that stirring groove top internal temperature holds
Continue stable requirement.There are two the front arch 8 of semicircle ring structure, two front arch 8 to form circle for installation in the small end of stepped cavity
Ring structure, and then guarantee the heat preservation of cavity top.
Structure brick 5 is installed, the structure brick 5 includes the structure brick sheet of step arc structure in the circular ring structure
Body, the structure brick ontology be provided with it is multiple, combination be formed as step cylindrical structure；Structure design can be in process of production
Dismounting and change is carried out, since internal-external temperature difference actual at the top of stirred tank will will cause a large amount of volatility object inside stirred tank
Matter is precipitated to the cold in the interface zone that temperature reduces, and then is attached on these interfaces, with the accumulation of time, these precipitates
It can be increasing and may fall into the glass metal in stirred tank, cause defect.Therefore, this structure brick 5 is replaced original
Fixed interface can periodically carry out dismounting and change to it, i.e., regularly be cleared up the particulate matter of precipitation, avoid its heap
It accumulates and falls.
It is placed with stirring rod in the cavity of the cylindrical structure, the lateral wall of the stirring rod is interior with cylindrical structure cavity
Gap between side wall is 15~20mm, this gap be under the premise of meeting stirring rod and protruding into stirred tank inside as far as possible
The gap between barred body and brick is reduced, avoids gap excessive, the loss of internal heat.
Meanwhile the step surface of structure brick 5 is in contact with the upper surface of front arch 8, in the actual production process, due to three valves
The inner wall of formula front arch 5 will become the interface of coagulation attachment accumulation, it is therefore desirable to which periodic replacement cleaning, the structure to tie
Structure brick 5 is replaced fairly simple.
The heating rod 1 of one U-shaped structure is installed, the open end of the heating rod 1 is worn on each side insulating brick 4
The square block 3 of 4 upper end of side insulating brick setting is crossed, and is fixed on square block 3 by the clip 2 of metal material.
The square block 3 is alumina-silica thermal insulation material, can remain unchanged shape at a high temperature of 1450 DEG C or more；Its side length
For 115mm.
Side insulating brick 4 and side wire vent insulating brick 6 it is identical, be the eccentric circular ring knot of outer diameter 710mm, internal diameter 360mm
Structure；Wherein, the wire hole 7 out for being three diameters for 10mm is offered on the outer wall of side wire vent insulating brick 6, for internal heating
Silk is drawn wiring and is used.
Cavity area 9 and current heater outer wall form the gap of 60mm, the gap can be formed meet heat storage and
Inward basic demand can be adjusted correspondingly in actual design according to the requirement of heating rod power.Due to current
Stirred tank top heater is using the radiant heating method and power limit of platinum heating wire form, and the temperature of cavity area 9 is only
1300 DEG C or so can be reached.And from the point of view of current service condition, there is also coagulation on the heater inner wall of cavity inside,
Therefore after being heated using this auxiliary, the temperature of internal cavities 9 can be promoted to 1400 DEG C or more, coagulates volatile matter here
Knot accumulation or a small amount of condensation.
