Description
Technical field
The utility model belongs to the observation pore structure on glass annealing process field more particularly to a kind of annealing kiln.
Background technique
Annealing kiln is to the equipment of glass " annealing " on glass production line, it makes the advancing glass tape come out from molten tin bath
From 600 DEG C it is controlled be cooled to 70 DEG C, while eliminating or reducing the residual stress of glass, inside of glass plate structure is made to tend to be equal
It is even, make it have good mechanical performance.Peep hole on annealing kiln is for the ease of each position situation in observation kiln, including kiln
Interior glass, roller, internal air hose, electric heater etc., arrange one on the two sides side wall of the every section kiln body of annealing kiln.?
Usual peep hole design structure rectangular hole style in production, under the premise of observation hole site determines, vertical direction is seen
It examines visual angle and is generally 0~37 °, horizontal direction observation visual angle is generally 0~58 °, the observing effect in the two angulars field of view
Unsatisfactory, viewing blind zone and dead angle are very big.Such as by the observation of kiln body side not it is observed that this side glass edge, will see
It must be observed to this side glass edge situation by kiln body other side peep hole；It is seen again because each peep hole horizontal view angle is limited
It is smaller to examine range, to see glass any position, it is necessary to which in kiln body to open peep hole, reality is three meters of long kilns of every section more
A peep hole is respectively opened in body two sides, and it is overstocked unfavorable to insulation of furnace wall to observe pore size distribution, and appearance is also unsightly.
Utility model content
The purpose of this utility model is by providing a kind of annealing kiln peep hole for improving observation pore structure, optimization annealing
Observation vision on kiln side wall.
The basic technical scheme of the utility model are as follows: the side wall of annealing kiln kiln body is arranged in a kind of annealing kiln peep hole
On, peep hole surrounding hole wall includes rectangular section and on the inside of the rectangular section, the oared segrne pii that connect with rectangular section.
Based on above-mentioned technical characteristic, oared segrne pii and the angle in face where the hole wall of rectangular section phase the same side are 30 °.
Based on above-mentioned technical characteristic, rectangular section accounts for the 2/3 of the observation hole depth.
Based on above-mentioned basic technical scheme, the hole wall of peep hole is folding shape steel plate, rolls over shape steel plate by plain plate and flanged plate
Composition, the flanged plate turn down form horn mouth outward.
Based on above-mentioned technical characteristic: the angle in face is 30 ° where flanged plate and plain plate phase the same side hole wall.
Based on above-mentioned technical characteristic: flanged plate turns down at the 2/3 of observation hole depth, and plain plate accounts for observation hole depth
2/3.The purpose being arranged so is to guarantee side wall heat-preservation cotton thickness.Side wall is made of outside plate, inside steel plate, heat-preservation cotton
It is filled between inside and outside steel plate, mainly plays function of heat insulation.
The hole wall of peep hole surrounding in the prior art is changed to folding face by plane by the utility model, horizontal wall surface end to
Outer folding edge, peep hole style are changed to flared hole by original rectangular opening, i.e., close to kiln body inside wall consent surrounding seben in side
Shape is horn-like.Visual angle effect of optimization is unobvious if the fold angle of flanging section is too small, if the fold angle of flanging section is too
It is big then visual angle further expansion can be hindered by turning down crest line.So for the annealing kiln generally used currently on the market, flanging section to
Outer 30 ° of fold is the selection of optimization, and the vertical direction observation visual angle to before improving can be improved in vertical direction observation visual angle since then
About 1.5 times；About 1.3 times of the horizontal direction observation visual angle to before improving can be improved in horizontal direction observation visual angle；Visual angle is aobvious
It writes and expands.
After observation visual angle increases, the range that can be seen by a peep hole is wider, can monitor situation in kiln on a large scale.
When occurring to anneal abnormal, for example fried plate problem occurs, when tracking lookup glass rupture source by peep hole, does not have to open all
Peep hole can easily see the position of glass rupture, and then quick positioning question by opening several wide angle viewing holes
Region.And the edge situation of observer place side glass can not only be seen by wide angle viewing hole, it is deposited before eliminating
Vision dead zone, moreover it is possible to observe air hose and electric heater situation inside upper edge that can't see in the past upwards.
