Description
Technical field
The utility model relates to a kind of technical field of glass tempering furnace, is specifically related to a kind of heat balance system of glass tempering furnace.
Background technology
" heat balance system " of traditional glass annealing furnace all is to adopt pressurized air in the factory as source of the gas, and externally extracting air is sent in the body of heater, makes generation air-flow in the body of heater; Because being blown into stove intravital is cold wind, cold wind mixes with the intravital heat of stove; The intravital temperature of stove is descended, and the intravital temperature of stove fails to reach predefined temperature, when making the intravital temperature of stove reach temperature in advance; Strengthen the power of body of heater internal heater; This mode can make the use cost of annealing furnace increase, and the loss great amount of heat causes the wasting of resources; Have again, when cold wind blows to the high temperature glass material, can make high-temperature glass material flexural deformation, pit etc. occur, cause glass material defective, integral body to scrap.For this reason, people have improved " heat balance system ", when air-supply, earlier cold wind are heated; Make that to send into stove intravital be hot blast, still, the intravital temperature of hot blast of sending into and stove still has deviation; Thereby, temperature inductor is set in body of heater detect stove body temperature in real time, with the temperature of adjustment well heater; This mode has been avoided high-temperature glass material flexural deformation, the phenomenon of pit occurred, still, fails to reduce the body of heater use cost; Cost is further increased, and also relative complex of structure, not easy to operate.
The utility model content
The purpose of the utility model is in order to solve the deficiency that above-mentioned prior art exists, and a kind of rational in infrastructure, glass tempering furnace that use cost is low and simple to operate is provided.
The purpose of the utility model is to realize like this.
A kind of glass tempering furnace comprises furnace shell, and the furnace shell along continuous straight runs is divided into preheating thorax, high temperature thorax and cooling thorax; Furnace shell wall inboard is provided with thermal insulation layer; The medium position along continuous straight runs is provided with row's heating wire being divided into two portions up and down in the chamber in the chamber of said preheating thorax, and the heating wire below is the heating zone, and the heating wire top is for forcing the wind-guiding district; Said pressure wind-guiding is provided with extractor fan in the district; The heating zone exhausting that the blast inlet of extractor fan faces toward is downwards seen off by air outlet, makes the preheating thorax form hot air circulation and flows, and the motor that drives extractor fan is located at outside the furnace shell wall.
Extract the hot blast in the preheating thorax through extractor fan, the air outlet by extractor fan blows out again, and the interior hot air circulation that forms of preheating thorax is flowed, and when the glass material gets into the preheating thorax, can quicken to be heated.
Technique scheme also can be done following further perfect.
The blast inlet of said extractor fan is arranged at the breech of preheating thorax; The air outlet of extractor fan is the preceding thorax to the preheating thorax of stretching.Air outlet is arranged on the preceding thorax of preheating thorax and breech that blast inlet is arranged on the preheating thorax forms the hot air circulation convection current, so that the temperature in the preheating thorax reaches balance.
The beneficial effect of the utility model is.
The utility model provides a kind of glass tempering furnace; In the preheating thorax, extractor fan is housed, from the blast inlet suction, the air outlet by extractor fan blows out extractor fan again with the heat in the preheating thorax; Make the preheating thorax form the hot air circulation convection current; Guarantee preheating bore temperature balance, this kind mode is simple and reasonable for structure, and is simple to operate; Make full use of the heat in the thorax, can not cause the wasting of resources, also can not increase use cost; And, the quality of assurance product.
Description of drawings
Fig. 1 is the structural representation of glass tempering furnace.
Fig. 2 is the enlarged diagram of preheating thorax.
Embodiment
Below in conjunction with accompanying drawing utility model is done further to detail.
To shown in Figure 2, a kind of glass tempering furnace comprises furnace shell 9 like Fig. 1; Furnace shell 9 is arranged on the grate 1, and furnace shell 9 along continuous straight runs are divided into preheating thorax 3, high temperature thorax 4 and cooling thorax 5, and furnace shell 9 wall inboards are provided with thermal insulation layer 7; Grate 1 is equipped with feeding ceramic roller 2; Ceramic roller 2 rolls and drives glass material entering preheating thorax 3, and the medium position along continuous straight runs is provided with row's heating wire 6 being divided into two portions up and down in the chamber in the chamber of said preheating thorax 3, and heating wire 6 belows are heating zone 31; The glass material receives the heat of heating zone 31 during through heating zone 31; Heating wire 6 tops are for forcing wind-guiding district 32; Be provided with extractor fan 8 in the said pressure wind-guiding district 32; Heating zone 31 exhausting that the blast inlet 802 of extractor fan 8 faces toward are downwards seen off by air outlet 803 again; Make preheating thorax 3 form hot air circulation and flow, accelerate the preheating of glass material, the motor 801 that drives extractor fan 8 is located at outside furnace shell 9 walls.After the preheating of glass material; Get into high temperature thorax 4 with ceramic roller 2, the glass material receives under the high temperature action of high temperature thorax 4, further heating; When the glass material fully heat reach a high temperature after; Ceramic roller 2 is sent into cooling thorax 5 to the high temp glass material, and cooling thorax 5 cools off the high temp glass material fast and makes glass material surface form the tempering effect, goes out thorax at last.
The effect of extractor fan 8 is the hot blasts that extract in the preheating thorax 3 through extractor fan 8, and the air outlet 803 by extractor fan 8 blows out again, and the preheating thorax 3 interior hot air circulation that form are flowed, and when the glass material gets into preheating thorax 3, can quicken preheating.
The blast inlet 802 of said extractor fan 8 is arranged at the breech of preheating thorax 3; The air outlet 803 of extractor fan 8 is the preceding thoraxes to preheating thorax 3 of stretching.Air outlet 803 is arranged on the preceding thorax of preheating thorax 3 and breech that blast inlet 802 is arranged on preheating thorax 3 forms convection current, reaches the temperature equilibrium in the preheating thorax 3.
Said extractor fan 8 is high temperature resistant blower fan, guarantees extractor fan 8 excessive damage of can not being heated.
