Description
Technical field
The utility model relates to refrigerating unit used in ultra-thin toughened glass production process, particularly relates to the air-cooling device that a kind of roots blower is applied in ultra-thin toughened glass industry.
Background technology
The product of toughened glass has been widely used in the various fields such as building, aviation, automobile, steamer, locomotive, electron display device.Toughened glass obtained Section 1 patent from 1870 in France to be begun, and obtains several patents, and industrially applied in 1892 in 19th-century.A series of products such as flat toughened glass, curved tempered glass are developed afterwards, to the 1980s, along with the increase of glass new variety, toughened glass process industry has carried out the R and D of product innovation, at the low emissivity glass tempering of building energy conservation window, the large-scale and different in nature glass tempering etc. of vehicle glass has considerable progress.Physical toughened glass forms compressive stress layer at glass surface, makes it increase a prestress to improve strength of glass, current widespread use be fast wind cooling tempering (be called for short air hardening steel) method.Air hardening steel is by more than glass heats to glass tempering transition temperature (Tg) 80 DEG C, utilize air as heat-eliminating medium, fast glass surface heat is taken away, glass outer cooling is very fast, and center of glass is cooled by thermal conduction by glass outer, therefore center of glass relative to glass outer layer cool slower, so create internal stress by this process in glass outer layer and centre portions, and the ultimate compression strength of glass is more than ten times of its tensile strength, by the introducing of internal stress, add the tensile strength of glass, the intensity of glass is improved.Under normal circumstances, doubly, hot chilling stability can be increased to 280-320 DEG C by about 150 DEG C to the intensity height 4-6 of toughened glass strength ratio common annealing glass.The intensity of toughened glass depends primarily on the size of internal stress, and with the tempering temperature of glass, rate of cooling is relevant.Generally, tempering temperature is 600-680 DEG C, heat-eliminating medium is air at room temperature, flowed with heat at hot glass surface by air, freeze glass surface, therefore, cooling power affects the degree of the temper of toughened glass to a certain extent, and then affects the intensity of toughened glass and broken rear fragment granularity.Degree of the temper increases, and the bending strength of glass and resistance to impact shock increase.But the temperature that the heat-eliminating medium used in view of air hardening steelization is air and air itself causes its refrigeration capacity limited with thermal capacitance, even if increase blast can not be applied to the mistake toughened glass of the thin glass of tempering (as thickness is less than or equal to the glass of 3mm) and specific demand.Increase blast simultaneously and mean increase fan capacity, current consumption increases rapidly, and cost increases substantially.
The tempering of ultra-thin glass, general plate face is little, lightweight, needs high pressure, middle flow cooling source; The tempering of traditional ultra-thin glass, generally adopts in two ways, and high pressure centrifugal fan or air compressor do source of the gas, then carries out cooling tempering by cooling air grid to glass.
But above two kinds of modes all also exist deficiency.Although high pressure centrifugal fan can provide larger flow, the pressure energy provided is less; Do with pressurized air the pressure that source of the gas can provide larger, but large flow can not be provided continuously.Therefore, when the ultra-thin glass tempering of tempering with homalographic, just need to be equipped with multiple stage heavy-duty motor and meet the demands, just substantially increase production cost, and it is high to consume energy, be unfavorable for producing in enormous quantities.
With reference to accompanying drawing 7, existing cooling air grid is commercially all rear portion air inlet mode from the side in addition, there is larger stress extreme difference in the glass surface completed after tempering, the bad control of glass flatness, the self-destruction rate of toughened glass is very high simultaneously, although rear portion air inlet mode structure is simple, there is blast problem of non-uniform in the rear and front end that there is air knife; Greatly can improve the self-destruction rate of toughened glass, cause damage.
Simultaneously, in Data of China storehouse, the air cooling system of glass tempering is retrieved, and retrieve a Chinese patent: ZL201210552329.X, a kind of toughened glass method of cooling and annealing furnace cooling system, its concrete structure is: comprise the blower fan sending into air to annealing furnace, air collecting box and air-supply passage, this air collecting box or air-supply passage are installed the liquid nitrogen container that holds liquid nitrogen, liquid nitrogen container has valve port to be connected with air collecting box, and this valve port is equipped with the magnetic valve online with fan starting, in the glass quenching stage, blower fan is used to send into air to annealing furnace, it is characterized in that, inject the quench process of liquid nitrogen to the short period of time in the air collecting box be connected with blower fan while being included in blower fan feeding air, make the combination cooling medium forming air and gasification liquid nitrogen in air collecting box, and make this combination cooling medium be admitted to the high temp glass of quenching tempering stove in annealing furnace by air-supply passage.Its structure by being equipped with low temperature liquid nitrogen input system in annealing furnace air cooling system, and liquid nitrogen temperature is subzero 196 DEG C, and by low temperature liquid nitrogen is incorporated into air cooling system, liquid nitrogen gasification, with air mixed, reduces the temperature of heat-eliminating medium.And then improve the tempering intensity of glass, but this technology needs to be coordinated by low temperature liquid nitrogen, will increase the unnecessary cost of equipment like this, and low temperature liquid nitrogen also needs to process, and the energy consumption making it process increases.
