Description

A kind of clarifying plant of TFT substrate glass delivery system

Technical field

The utility model relates to base plate glass and manufactures field, is specifically related to a kind of clarifying plant of TFT substrate glass delivery system.

Background technology

In TFT-LCD base plate glass is produced, because the specification of quality of base plate glass is high, need to reduce the deficient point of gaseous state and solid inclusions etc. in glass as much as possible.

In glass production, starting material devote in melting kiln and carry out melting, due to starting material physical aspect change at high temperature and the chemical polymerization of each storeroom, make in the glass melt of fusing containing a large amount of bubbles, and the different diameters of bubble is huge, along with the change bubble of temperature also constantly produces, assembles.In these bubbles, most of portion excludes from flue.Through kiln discharge port, because certain temperature drop makes part gas bubble in glass metal, now need further process, got rid of the remaining bubble in glass metal by the temperature raising melten glass body further.

If the diameter of residual bubble is greater than specific specification value in glassy product, so it is exactly defective products.So clarifying treatment, namely bubble is discharged, it is a key in technology for making glass, for liquid crystal substrate glass, only area is large and due to the requirement of display performance, bubble is a defect to life especially, in other words in liquid crystal substrate glass technical field, clarifying treatment, namely discharges bubble, especially a gordian technique.

Utility model content

In order to realize above utility model object, the technical scheme that the utility model adopts is: the horizontally disposed Transfer pipe in exit being included in melting kiln, Transfer pipe top is provided with several venting holes, described Transfer pipe is provided with heating unit, and heating unit can control the temperature of molten glass; Several flow aprons are provided with in described Transfer pipe, several described flow aprons one group between two, some groups of flow aprons are axially arranged in order along Transfer pipe, two flow aprons often organized are oppositely arranged, the shape of flow apron and the shape of cross section of Transfer pipe match, the side of flow apron can be close to the inwall of Transfer pipe, and has the space that molten glass can be made to flow through between two flow aprons often organized.

Some groups of described flow aprons are along the axial staggered arrangement of Transfer pipe, and wherein two flow aprons of a group are arranged on the upper and lower inwall of Transfer pipe, then two flow aprons of a group that is adjacent are arranged on the left and right inwall of Transfer pipe.

Space between often organize two described flow aprons is of a size of 1/5 ~ 4/5 of the cross-sectional dimension of Transfer pipe.

Described flow apron is 1 ~ 4 group.

The cross section of described Transfer pipe is circular, oval or Polygons.

The material of described Transfer pipe is for being selected from platinum, rhodium, ruthenium, iridium, osmium, palladium, molybdenum or its alloy.

The power of described heating unit is 10 ~ 50kW, the temperature of molten glass can be controlled at 1550 DEG C ~ 1680 DEG C.

Compared with prior art, the utility model comprises the Transfer pipe of horizontal positioned, the heating unit that Transfer pipe is arranged, control the temperature entering the molten glass of Transfer pipe, force the Bubble be dissolved in glass metal, discharged by the venting hole release being arranged on Transfer pipe top, be provided with in Transfer pipe and organize flow apron more, often group is two flow aprons be oppositely arranged, in the process of circulation of glass metal, glass metal can only be flowed out from the space between two flow aprons, many groups flow apron combines, force the glass metal laminar flow flowed through interlaced, serve the effect of density homogenizing and bubble rising discharge, the utility model can effectively homogenize and reduce bubble, improve the quality of TFT substrate glass.

Further, flow apron, along the axial staggered arrangement of Transfer pipe, by labyrinth channel, makes the glass metal laminar flow that flows through interlaced, more promotes that the density homogenizing of glass metal and bubble rise and discharge.

Further, the void size between two flow aprons often organized ensures enough sizes, ensure that glass metal can pass through space, ensure the fluency that glass metal circulates, simultaneously again can be interlaced fully, promote that density homogenizing and bubble rise and discharge, improve the quality of base plate glass.

Further, Transfer pipe takes different shapes the requirement of satisfied different space enrironment, adopts high temperature resistant, corrosion-resistant material to make, improves the performance of Transfer pipe, and work-ing life.

Further, heating unit can control molten glass in suitable temperature, ensure that normally carrying out of lower procedure, improves the quality of base plate glass.
