Embodiment of the present utility model provides a kind of heat ray filter for ingot furnace crucible, including being installed on ingot furnace
Backplate outside crucible 1 and be positioned at and protect felt 2 outside backplate 1, backplate 1 is provided with at least two the first through hole 3, and the first through hole 3 passes through
The thickness direction of logical backplate 1, protects the correspondence position of felt 2 and is provided with the second through hole 4, the second through thickness direction protecting felt 2 of through hole 4,
When backplate 1 with protect the second through hole 4 when felt 2 is drawn close and should align one by one with the first through hole 3, its quantity can be not equal to the first through hole
The quantity of 3 but the most should be less than two, heat ray filter also includes sequentially passing through the rotating of the first through hole 3 and the second through hole 4
Latch, the first through hole 3 and the second through hole 4 are equipped with the step surface for clamping latch.
Application above-described embodiment provide when the heat ray filter of ingot furnace crucible, latch sequentially passes through the first through hole 3
With the second through hole 4, then rotate latch and make latch and the reference azimuth entering through hole stagger so that latch can be with the first through hole
3 and the second step surface snap-fit of through hole 4, it is ensured that backplate 1 and protect effective between felt 2 fixing connect.Meanwhile, first leads to
Hole 3 and the second through hole 4 at least two respectively, it is to avoid backplate 1 and protect felt 2 by single hole list pin connection can occur crooked existing
As.
Meanwhile, the heat ray filter for ingot furnace crucible that above-described embodiment provides is convenient dismounting during coming out of the stove, and turns
Dynamic latch makes latch overlap with the reference azimuth entering through hole can easily to take out latch and remove and protect felt 2, saving workman's
Labour, improve work efficiency.
In order to optimize the using effect of latch in above-described embodiment, latch includes inserted link 6 and lays respectively at inserted link 6 two ends
Plug 5, inserted link 6 preferably employs cylinder inserted link 6, and the plug 5 at two ends preferably employs identical size and profile, the first through hole 3 He
Second through hole 4 is equipped with the opening 7 matched with plug 5, matches and is meant that profile is consistent or similar and the size of opening 7
With the equivalently-sized of plug 5 or slightly larger than the size of plug 5, in order to plug 5 can stably insert in opening 7.If no
Being preferably provided with the opening 7 matched with plug 5, latch still may be inserted in the first through hole 3 and the second through hole 4, but does not open
The position-limiting action of mouth 7 can make whole insertion process less stable reliable, and latch can occur crooked existing the most during insertion
As.
In order to optimize the using effect of backplate 1 in above-described embodiment, opening 7 extends less than backplate 1 thickness inside backplate 1

Head, opening 7 is specially yi word pattern opening or circular arc opening accordingly.Use yi word pattern plug then plug 5 and the processing of opening 7
The most more convenient, and yi word pattern plug is simple and practical, it is simple to gripping and rotating operation；Circular arc plug is used then to install stable
Property is higher, and service life is longer.
In the another kind of specific embodiment that this utility model provides, the first through hole 3 is positioned at sustained height on backplate 1, the
Two through holes 4 are positioned at and protect sustained height on felt 2.By the preferably first through hole 3 and height value of the second through hole 4, it is ensured that backplate 1 He
Protecting felt 2 can upright use, namely backplate 1 and protect felt 2 height value everywhere and can be uniformly distributed, integral installation is got up relatively
For convenience of attractive in appearance, and can reach uniformly to block thermal-radiating effect.Certainly, if crucible being heated and uneven, then everywhere
The height value of felt 2 can also be protected by change and adapt to corresponding heat affected zone.
In order to optimize backplate in above-described embodiment 1 and protect the using effect of felt 2, the first through hole 3 is positioned at the height on backplate 1
It is equal that value and the second through hole 4 are positioned at the height value protected on felt 2.By further preferred first through hole 3 and the height of the second through hole 4
Value so that backplate 1 and to protect felt 2 concordant bottom it after latch connection, it is achieved that more perfect effect of heat insulation, also makes respective
Size can obtain more precise control, it is simple to the Scheme Choice of designer and the correspondingly-sized processing of processing staff.
In a kind of concrete performance, we can a length of with backplate 1 upper shed 7 of preferred length 1130 millimeters
13 millimeters, two openings 7 are 26 millimeters from backplate 1 respective side, and it is 6 that extension end connects a diameter of 15 mm depths
The circular hole 8 of millimeter, two circular holes 8 are 25 millimeters from backplate 1 respective side, and long protecting of 1130 mm wide 210 millimeters is opened on felt 2
A length of 13 mm in width of mouthfuls 7 are 10 millimeters, and the axis of the first through hole 3 and the second through hole 4 is all apart from backplate 1 or protect felt 2
105 millimeters, bottom, inserted link 6 is the cylinder inserted link 6 of diameter 6 height 52 millimeters, and plug 5 is high 5 millis of long 12 mm wide 9 millimeters
The cuboid plug 5 of rice, the midpoint of plug 5 is positioned on the straight line at centrage place of inserted link 6.Above-mentioned selection of dimension is only used as one
Individual preferred scheme, according to the dimensions difference of crucible can with other preferred sizes of unrestricted choice and profile scheme, or
Parts equal proportion in the present embodiment is zoomed in or out by person, in this no limit.
Based on the heat ray filter provided in above-described embodiment, this utility model additionally provides a kind of ingot furnace, this ingot furnace
Including any one heat ray filter in above-described embodiment.The heat ray filter in above-described embodiment, institute is have employed due to this ingot furnace
