Abstract
The utility model relates to a vacuum thermal insulation board for a glass fiber wire drawing furnace, which is composed of two layers of glass bodies, a plurality of cylindric fulcrums, an air extraction sealing valve, a plurality of bolts and a plurality of nuts, wherein, the inner surfaces of the glass bodies are silvered. Because the inner surfaces of the two layers of the glass bodies are silvered, so a vacuum is formed in the middle interlayer; thereby, the air movement can be effectively blocked, and the insulating efficiency is high. The cylindric fulcrums are used for supporting the two layers of the glass bodies, which can bear the great pressure.
Description
The utility model relates to a kind of building thermal insulation material, exactly is the glass fiber drawing furnace vacuum heat-insulation plate.
The insulation layer of existing glass fiber drawing furnace adopts asbestos insulation board and high alumina foam thermal insulation brick, and insulating efficiency is low, and volume is big, and the application life of high alumina foam thermal insulation brick is lower.
The purpose of this utility model is to provide a kind of insulating efficiency height, and volume is little, the vacuum heat-insulation plate of long service life.
The technical scheme of utility model is achieved in that vacuum heat-insulation plate mainly is made of two-layer identical vitreum, intermediate course forms a vacuum, the vitreum inner surface is silver-plated, the cross section of vacuum heat-insulation plate is several ellipse garden gap structures, and arc intersection, two ellipse gardens of vitreum is provided with several Cylinder fulcrums.Adopt cementing agent to be bonded and sealed around two vitreums, use bolt and nut fastening again.Side at vacuum heat-insulation plate is equipped with the draught excluder of bleeding, and vacuum heat-insulation plate layer glass interlayer body is evacuated.
The advantage of utility model is: the vacuum interlayer of vacuum heat-insulation plate can be blocked air movement, insulating efficiency height effectively; Support by the Cylinder fulcrum between two vitreums, can bear bigger pressure.
The concrete structure of utility model is provided by following examples and accompanying drawing.
Accompanying drawing 1: be the structure chart of vacuum heat-insulation plate.
Describe the concrete structure of utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, vacuum heat-insulation plate is made of layer glass body 1,5, the draught excluder 4 of bleeding, Cylinder fulcrum 6 and bolt and nut 2,3, vitreum 1,5 inner surfaces are silver-plated, and it is the groove of half ellipse garden shape that seven cross sections are arranged, make the vacuum heat-insulation plate cross section that shape space, seven ellipse gardens be arranged, arc intersection, vitreum 1,5 ellipse garden is provided with Cylinder fulcrum 6, adopt cementing agent 7 to be bonded and sealed around the layer glass body 1,5, use bolt and nut 2,3 fastening again, the vacuum heat-preserving intralamellar part is evacuated from the draught excluder 4 of bleeding.
Claims (3)
1, a kind of mainly by layer glass body 1,5, the vacuum heat-insulation plate that the draught excluder 4 of bleeding constitutes, it is characterized in that: there is Cylinder fulcrum 6 to be supported on arc intersection, the ellipse garden of vitreum 1,5 inner surfaces between the vitreum 1,5, fastening around the layer glass body 1,5 with bolt and nut 2,3.
2, vacuum heat-insulation plate according to claim 1 is characterized in that: vitreum 1,5 inner surfaces have seven grooves, and cross section is ellipse garden shape half.
3, vacuum heat-insulation plate according to claim 1 is characterized in that: vitreum 1,5 inner surfaces are silver-plated.
