Description
Technical field
The present invention relates to distiller's yeast production equipment field more particularly to glass plate cooling devices.
Background technique
Glass is to be fused together to be formed by silica and other chemical substances, forms contiguous network knot in melting
Structure, cooling procedure medium viscosity are gradually increased and harden the silicates nonmetallic materials for causing it to crystallize.Simple glass it is main
Ingredient is silicate double salt, is a kind of non-crystalline solids of random structure, is widely used in building, is used to every wind light transmission.
In modern architecture, the demand of glass is more and more, and thus people largely produce glass, produces glass
General technology are as follows: 1, raw material preprocessing: block stock (quartz sand, soda ash, lime stone, feldspar etc.) is crushed, moist raw material is made
It is dry, iron-bearing material handle except iron, to guarantee glass quality；2, prepared by batch: according to the difference of product, batch
Composition slightly distinguish.Such as the batch (being calculated according to 50 kilograms) of common float glass, it is public to need to consume quartz sand 33.55
Jin, 2.96 kilograms of lime stone, 8.57 kilograms of dolomite, 11.39 kilograms of soda ash, 0.55 kilogram of saltcake, 3.45 kilograms of feldspar, carbon dust
0.03 kilogram；3, be melted: glass batch carries out high temperature (1550-1600 degree) heating in tank furnace or pot furnace, is allowed to be formed
Uniformly, bubble-free and meet the liquid glasses of forming requirements；4, it forms: liquid glass is processed into the product of required shape,
Such as plate glass, various vessel；5, be heat-treated: by the techniques such as annealing, quench, eliminate or generate inside glass stress,
Split-phase or crystallization, and change the configuration state of glass；6, cooling: the glass sheet temperatures after annealing are higher, easily deform,
It needs for the glass plate of high temperature to be transported to, be cooled down in cooling device.In cooling step, the existing type of cooling is by glass
It while glass plate is transmitted by roller conveyor, is cooled down using air-cooled intensifying device, usually setting supplies on a moving belt
The cooling storehouse that glass plate passes through installs air outlet on cooling bulkhead, leads to cold wind using air outlet and cool down to glass plate, out
When tuyere is to glass plate blowing cold air on conveyer belt, cold wind can directly be cooled down glass plate upper surface, table on glass plate
Face cooling is very fast, and the lower surface cold wind that glass plate is contacted with conveyer belt would become hard to pass through, and the cooling rate of lower surface is slower, from
And cause glass plate cooling uneven.
For this purpose, application No. is 201420858107.5 patent documents to disclose a kind of cooling device of glass production line,
Including the top heat exchange mechanisms of glass top surface are arranged in and the lower part cooling device of lower glass surface is arranged in, the cooling dress in top
It sets including multiple spaced air-breathing tanks, opening is arranged at air-breathing pot bottom and top, and upper opening passes through blower and external environment
Communicate, be provided with top water cooling plant between every two air-breathing tank, top water cooling plant include the cooling tube being arranged from top to bottom,
The outer surface of upper power roller and upper rotating roller, upper rotating roller coats water-absorbent material, and the bottom of cooling tube is provided with weeper, cooling
Water is fallen on water-absorbent material after weeper leakage, and the hot gas generated in cooling process is discharged to by the opening on air-breathing tank
In external environment；Lower part cooling device includes multiple sinks being continuously arranged, and lower part water cooling plant, lower part water cooling are provided in sink
Device is corresponding with top water cooling plant, lower part water cooling plant include: from top to bottom be coated with water-absorbent material lower rotating roller and
Lower power roller, lower power roller rotation drive the rotation of lower rotating roller, and bottom of gullet accumulates cooling water, a part of lower power roller
It is immersed in cooling water, cooling water is transferred in the water-absorbent material outside lower rotating roller after power roller rotation.This scheme passes through upper
Power roller, lower power roller are driven the glass after annealing, and the water-absorbent material by coating in upper power roller, lower power roller
It absorbs cold water to cool down to glass, heat is also siphoned away by air-breathing tank and carries out auxiliary temperature-reducing, to reach lowering temperature uniform
Effect.
Although the non-uniform problem of cooling that above scheme solves, but still has certain problems, 1, the glass after annealing
Glass plate will be contacted directly with water, and high temp glass plate is cooled suddenly will be easy to burst；2, cold water is directly contacted with high temp glass, will
A large amount of water is evaporated from device by thermosetting water vapour, will cause a large amount of wastes of water resource.
Summary of the invention
The invention is intended to provide one kind to prevent high temp glass plate from bursting, the cooling dress of glass plate of water resource can be also saved
It sets.
Glass plate cooling device in this programme, including cooling box, the side of cooling box are provided with opening, and opening rotation connects

Mechanism.
The technical principle of this programme: when cooling box is used for the cooling of high temp glass plate, confined space is formed, is avoided outside cold air
Leakage；The setting of opening is for switching cooling box, and high temp glass plate is transported on the conveyer of cooling box by when opening, when closing
Cooling box is closed and prevents cold air from leaking outside；Heat exchange mechanisms are changed for cooling down to the glass plate being closed in cooling box
Heat engine structure can cool down the conveyer in cooling box, so that conveyer has lower temperature, conveyer inherently can be right
Glass plate cools down, the heat of conveyer heat absorbing glass plate, and conveyer temperature increases, and conveyer transfers heat to its week again
The air cooling through heat exchange mechanisms enclosed, while glass plate also transfers heat to the air cooling through heat exchange mechanisms, air is again
Heat exchange mechanisms are transferred heat to, heat exchange mechanisms take away heat, to achieve the purpose that cooling；Heat exchange mechanisms include being located at drop
