Technical field
The utility model relates to glass furnace, relates in particular to a kind of discharge structure of glass kiln.
Background technology
In glass industry, the agent structure of kiln (with glass metal contact part) all adopts and can form at the refractory material laying of to a certain degree resisting glass metal erosion.Use position difference, glass kind difference and end-use not equal according to refractory materials, alternative refractory materials comprises fused cast zirconia-alumina brick, the high zirconia block of founding and founding quartz brick etc.Although these high quality refractory bricks use on suitable kiln position through optimization design, Rational choice, it still inevitably can be corroded by glass metal, and the brick material that can not be melted completely by glass metal after erosion just forms impurity calculus.This class impurity is all greater than normal glass liquid because of density, viscosity, generally can concentrate to be deposited on kiln bottom construction, to form motionless metamorphic layer.In the middle and later periods in each furnace life, if clear up not in time the metamorphic layer glass of this part bottom deposition, it likely enters workflow and participates in moulding in the situations such as the slight variation of processing condition, forms product defects, affects quality product and good article rate.
At present, the method that solves glass furnace bottom and other motionless metamorphic layers in position is to open one or more straight type through holes or step through-hole (for platinum sleeve pipe is installed in kiln proper site, prevent from discharging for a long time glass metal and wash away brick material), and kept a plane by perforate refractory brick and next-door neighbour's brick material.Daily this hole is used refractory brick or the sealing of water-cooled plug, and when use, removing sealing can use, and this method is easy and simple to handle, and working cost is lower.But for viscous fluid, the bottom of fluid flows quite slow, metamorphic layer mostly is heavy, large viscosity zirconium white class material in addition, and its mobility is poorer; In addition, it is few that glass furnace bottom is subject to heat hot radiation, and bottom refractory brick heat radiation causes that bottom temp is lower, and metamorphic layer viscosity is greater than normal glass, causes metamorphic layer flow difficulties, even in motionless state.Even so discharge for a long time, the metamorphic layer of flow difficulties cannot be excluded.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, a kind of discharge structure of glass kiln is provided, solve discharge structure in current technology and be not easy to the discharge of metamorphic layer, in furnace bottom and other dead angles of kiln, constantly pile up, in the time that accumulation reaches certain thickness or change due to processing condition, will enter molding device with job stream, affect the problem of quality product and good article rate.
For solving above technical problem, the technical solution of the utility model is:
A kind of discharge structure of glass kiln, at the bottom of comprising kiln, is characterized in that, at the bottom of described kiln, is formed by the tap out block made from refractory materials and end brick masonry, and tap out block end face adopts funnel structure, offers tapping hole in the bottom of funnel structure.Kiln discharge structure described in the utility model adopts the funnel structure of sunk type, makes metamorphic layer can be subject to the effect of gravity along the downward landing in inclined-plane of funnel structure, is conducive to metamorphic layer and flows to tapping hole.When metamorphic layer thickness is increased to a certain degree, metamorphic layer flows the closer to normal glass liquid, temperature is higher, and viscosity is less, and it is less to be subject to kiln wall friction power, and metamorphic layer is just lower the closer to the portion temperature of kiln diapire face, viscosity is just larger, is subject to kiln wall friction power larger, due to the funnel structure of tap out block end face, the self gravitation of metamorphic layer can well overcome friction inhibition, thereby can guarantee metamorphic layer good go out to discharge from tapping hole.
Further, the angle of inclination, inclined-plane of the funnel structure of described tap out block is relatively conducive to metamorphic layer and flows into tapping hole discharge while designing between 0 °～60 °, in the time that pitch angle reaches 90 °, this structure has just been got back to through-type discharge structure, because easily there is the phenomenon of metamorphic layer drippage in the time that angle is excessive, the metamorphic layer tomography drippage of front end is discharged, thereby the metamorphic layer that cannot drive rear portion continues to flow, and does not have on the contrary the effect of good water conservancy diversion.
Further, described tapping hole is opened in a side of tap out block middle or melt flow direction, according to actual discharge structure, tapping hole position is set, and makes tapping hole can not hinder flowing of glass metal.
Further, described tapping hole is straight type through hole or step through-hole, while adopting step through-hole, can platinum sleeve pipe be installed at step place, prevents from discharging for a long time glass metal and washes away brick material.
Further, the end face of described tap out block also can play the effect of water conservancy diversion lower than next-door neighbour's end brick, contribute to the discharge of metamorphic layer.
Further, the difference of altitude of the end face of described tap out block and next-door neighbour's end brick is controlled in 50mm, tap out block and next-door neighbour's end brick difference of altitude can not be excessive, the excessive metamorphic layer that easily causes of difference of altitude forms impurity calculus at step place residual buildup, when production technique sharply changes, while rising as temperature, metamorphic layer viscosity degradation, the easy job stream that flows into along with glass metal.
Further, described tap out block and end brick adopt founding zirconium material, reduce the frictional force between metamorphic layer and refractory materials, promote flowing of metamorphic layer.Founding zirconium material can be casting zirconia corundum, can be also the high zirconia block of founding, high zirconia block better effects if, preferred high zirconia block.
Compared with prior art, the utility model advantage is:
Discharge structure of glass kiln described in the utility model can be widely used on all kinds of glass production lines, its have simple in structure, be easy to manufacture, Maintenance free, low operating cost, be applicable to the advantages such as scale operation, at the bottom of more fully discharging as kiln under the state that does not affect normal production, the metamorphic layer at the position such as dog-hole, supply channel, improve the comprehensive good article rate of product; And in the time that technique adjustment causes in stove that temperature sharply changes, can effectively reduce calculus quantity stable.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The disclosed a kind of discharge structure of glass kiln of the utility model embodiment, plays good guide functions to metamorphic layer, is convenient to the discharge of metamorphic layer, there will not be the accumulation of metamorphic layer in furnace bottom and other dead angles of kiln, improves the quality of products and good article rate.
Metamorphic layer in glass furnace starts just constantly to produce in furnace equipment operation, if got rid of not in time, it will constantly pile up in furnace bottom and other dead angles of kiln, but will enter molding device with job stream in the time that accumulation reaches certain thickness or changes due to processing condition.Below analyze the stressed mobility status of metamorphic layer:
Fig. 1 be the discharge of melting pool or supply channel while carrying out metamorphic layer flow and be subject to force mode, in figure taking certain particle in metamorphic layer as evaluating objects.The proal power of particle A is from job stream tensile force f 1 forward, and under the normal condition of production, F1 is constant; On reverse direction, due to the frictional force F2 producing between viscous liquid and wall, F2 is relevant to metamorphic layer viscosity, wall state etc.; And G is the gravity of particle A, approximately constant.This shows, what particle A moved moves under the suffered F1-F2 of making a concerted effort.When metamorphic layer thickness is increased to a certain degree, particle A is the closer to normal glass liquid stream, and temperature is higher, and viscosity is less, and it is less to be subject to wall friction power, and F2 is less, and F1-F2 is larger, and particle A will enter job stream, polluted product.In addition, when production technique sharply changes, while rising as temperature, metamorphic layer viscosity degradation, particle A equally easily enters job stream.
When normal operation, particle A is suffered to make a concerted effort in steady state, and particle A is near wall, and F2 is larger, thus near the metamorphic layer of wall substantially in motionless state, traditional discharge structure is difficult to metamorphic layer to discharge.
As shown in Figures 2 to 4, a kind of discharge structure of glass kiln, comprise at the bottom of kiln 1, at the bottom of kiln, 1 is built by laying bricks or stones and is formed by the tap out block 2 made from refractory materials and end brick 3, tap out block 2 adopts and the accurate wide design of passage, being conducive to metamorphic layer fully discharges, tap out block 2 end faces adopt funnel structure, offer tapping hole 4 in the bottom of funnel structure, funnel structure is conducive to metamorphic layer and flows to tapping hole 4, but not the pitch angle of funnel structure is the bigger the better, in the time that pitch angle equals 90 °, this structure is just got back to through-type discharge structure design, the pitch angle of funnel structure is controlled at and between 0-60 °, is relatively beneficial to metamorphic layer and flows into tapping hole and get rid of, tapping hole is positioned at funnel middle, also can the different perforates at position be set in a side of melt flow direction according to discharge structure.The straight type through hole of tapping hole 4 or step through-hole, for platinum sleeve pipe is installed, prevents from discharging for a long time glass metal and wash away brick material.
The end face of tap out block 2 is lower than next-door neighbour's end brick 3, and tap out block 2 end faces and next-door neighbour's end brick difference of altitude of 3 are controlled to 50mm contribute to flowing of metamorphic layer with interior.
Reduce the frictional force of laminar flow pattern metamorphic layer and wall, select the refractory materials of high-quality, tap out block 2 and end brick 3 adopt founding zirconium material, reduce the frictional force of metamorphic layer and refractory materials, promote metamorphic layer to flow.Tap out block 2 and end brick 3 can adopt fused cast zirconia-alumina brick, but this class material is subject to glass metal can form the transition layer that brick and glass metal are combined closely after corroding, and this class transition layer will increase wall friction power, be unfavorable for the mobile of metamorphic layer.Also can adopt the high zirconium of founding to make tap out block 2 and end brick 3, not have the transition layer between glass metal and brick, glass metal is less than zircon corundum brick in high zirconia block surface flow frictional force, is more conducive to metamorphic layer flow state.
Below be only preferred implementation of the present utility model, it should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim limited range.For those skilled in the art, not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
