Abstract
The invention relates to a heating furnace internal heat-insulating device, particularly a vacuum tube furnace internal heat-insulating device. The vacuum tube furnace internal heat-insulating device mainly solves the technical problems of difficulty in firing and processing, high cost and the like in the corundum heat-insulating plate. The technical scheme is as follows: the vacuum tube furnace internal heat-insulating device is a quartz glass plate cuboid cavity structure and is arranged on both ends in a vacuum tube furnace, the middle part of the cuboid is provided with a through hole, and the cavity is filled with heat-insulating asbestos fibers. In order to enhance the heat-insulating effect, the cavity is vacuumized. In order to increase the heat reflection effect of the quartz glass plate, a chromium coating is arranged on the surface facing with the inside of the furnace. The vacuum tube furnace internal heat-insulating device is mainly used for vacuum tube furnaces.
Description
Technical field
The present invention relates to heat-proof device, particularly a kind of vacuum tube furnace internal heat-insulating device in a kind of heating furnace.
Background technology
In superconducting tape quantity-produced vacuum drying oven, reel system need to pass through whole heating region, to unreel chamber and rolling chamber all needs to carry out heat insulation with the thermal treatment zone, simultaneously, due to the needs of production technology, also need to set up heating gradient faster, therefore, the heat insulation of the Yu Fei thermal treatment zone, the thermal treatment zone just seems especially important. In vacuum drying oven, keep the technological requirements such as cleanliness factor and material outgassing lack by needs, can not carry out heat insulation with traditional insulating brick, what use was more at present is corundum plate, as shown in Figure 1, thermal insulation board 8 is large scale corundum plate, fires difficulty large, price is very expensive, and difficulty of processing is large, off-standard size must customize grinding tool, and customization cost is higher.
Summary of the invention
The object of this invention is to provide a kind of vacuum tube furnace internal heat-insulating device, mainly solve corundum thermal insulation board and fire difficulty, difficult processing, high in cost of production technical problem.
Technical scheme of the present invention is: a kind of vacuum tube furnace internal heat-insulating device, for quartz glass plate tetragonal body cavity structure, be arranged on the two ends in vacuum tube furnace, and be provided with through hole at tetragonal body middle part, in cavity, be filled with heat insulation asbestos fibre. For increasing effect of heat insulation, cavity vacuumizes. For increasing the effect of quartz glass plate reflecting heat, there is chromium coating in the side in stove.
Useful technique effect of the present invention: keep the technological requirements such as cleanliness factor and material outgassing lack by needs in vacuum drying oven, can not carry out heat insulation with traditional insulating brick. Quartz glass plate heat resistance good (1200 DEG C), thermal coefficient of expansion is little, not yielding in heating process, and quartz glass plate good processability can require to customize according to various geomeries. The present invention is designed to thermal insulation board a vacuum cavity that heat insulation asbestos fibre is housed cleverly, has reached good effect of heat insulation in limited space; Heat source side is used back side chromium plating quartz glass plate simultaneously, can farthest reflect radiation heat be melted down in chamber, reaches heat insulation effect.

Fig. 1 is vacuum drying oven structural representation.
Fig. 2 is structural representation of the present invention.
Fig. 3 is effect of heat insulation comparison diagram of the present invention.
In figure: 1-quartz glass plate, 2-vacuum chamber, the heat insulation asbestos fibre of 3-, 4-through hole, 5-is put belt wheel, 6-take-up pulley, 7-superconducting tape, 8-thermal insulation board。
Detailed description of the invention
With reference to Fig. 1,2, a kind of vacuum tube furnace internal heat-insulating device, being mainly used in temperature, to reach the inside of large scale vacuum pipe furnace of 800 DEG C heat insulation, and insulation surface is 300mm*300mm. Insulator is quartz glass plate 1 tetragonal body cavity structure, be arranged on the two ends in vacuum tube furnace, lay respectively at and put belt wheel 5 and take-up pulley 6 both sides, be provided with through hole 4 at tetragonal body middle part, for the conveying of superconducting tape 7, in tetragonal body cavity, be filled with heat insulation asbestos fibre 3. For increasing effect of heat insulation, tetragonal body cavity is vacuum chamber 2. For increasing the effect of quartz glass plate 1 reflecting heat, there is chromium coating in the side in stove. Through contrasting with corundum thermal insulation board, as shown in Figure 3, it is better that effect of heat insulation of the present invention is wanted.
Claims (3)
1. a vacuum tube furnace internal heat-insulating device, is characterized in that, for quartz glass plate tetragonal body cavity structure, being arranged on the two ends in vacuum tube furnace, is provided with through hole at tetragonal body middle part, is filled with heat insulation asbestos fibre in cavity.
