The compound heating container of multiple spot temperature control
The utility model relates to a kind of compound heating container of multiple spot temperature control, is mainly used in the heated plate material, as in the glass heats stove to the heating of glass.
In traditional glass heats stove, each heating unit evenly is arranged near the upper and lower surface of glass, and heat mainly is delivered to the heating of the surface realization of glass to glass by the radiating mode.Radiation heating is the slowest a kind of mode of conducting heat in conduction, convection current, three kinds of type of heating of radiation, under equal temp of heating element, making glass reach same temperature needs long heat-up time, and heat-up time, length can make the optical quality of glass sustain damage.When being heated glass and being coated glass, owing to there is the one side of rete to have lower radiant ratio, heat is difficult to pass rete to glass heats by the radiating mode, it is longer that glass reaches the required time of requirement temperature, and the one side that does not have a rete is still with the heat absorption of heat absorption speed faster usually, so just cause the ununiformity of heat absorption down on glass, the optical quality of the glass after the processing is poorer.
Summary of the invention
In order to improve rate of heating as much as possible, to improve the optical quality of the glass after the processing, simultaneously, for the face one side heating difficulty that overcomes coated glass, the utility model provides a kind of compound heating container of multiple spot temperature control.
The technical scheme that its technical problem that solves the utility model adopts is: the heating unit that comprises the upper and lower that is installed in glass conveying roller way respectively, it is characterized in that: a plurality of described heating units are installed in one laterally for constituting the heating casing in the casing of one, a plurality of these heating casings are vertically arranged the upper and lower that is installed in described glass conveying roller way, in this heating container dignity the one side of glass conveying roller way are equipped with the radial lamella that has the wind hole; Be provided with spaced apart a plurality of backwind tube that communicates up and down in the centre of each this heating casing, on the blast inlet of the one or both ends of each this heating casing, blower fan be housed.
Described heating unit is installed in the part near glass conveying roller way, is provided with dividing plate between each heating unit of this part, in the zone of being cut apart by this dividing plate that each described heating unit occupied temperature control element is housed all.
Described radial lamella is dismantled and assembled structure, is connected on the described heating casing by voussoir.
Between described heating unit, set up exhaust duct.
The tubulose tuyere of the range that is used to increase wind is housed on the wind hole of described radial lamella.
The beneficial effects of the utility model are: can heat glass with radiation and convection current dual mode simultaneously,, can change radiation and convection current and add the proportion of pining for by adjusting blast, and can the subregion controlled temperature.More importantly because this casing is an integral body, design with make in guaranteed that all each regionally equates with the distance of glass.

Fig. 2 is a vertical structure synoptic diagram of the present utility model.
Among the figure: 1. blower fan; 2. heating casing; 3. heating unit; 4. backwind tube; 5. be with the radial lamella of air outlet opening; 6. glass; 7. rollgang; 8. voussoir; 9. lagging material and frame; 10. dividing plate.
The utility model is described in further detail in conjunction with the accompanying drawings now.
Referring to Fig. 1 and Fig. 2, the utility model comprises the heating casing 2 of (or the one) blast inlet that has two, and each blast inlet is installed a high-temperature blower 1.Heating casing 2 is dismountable except the one side towards glass 6 (being rollgang 7), rest part is changeless, the inside of heating casing 2 is when manufacturing and designing, part near glass 6 is separated into a plurality of zones by dividing plate 10, the thermopair (not shown) that each one group of heating unit 3 of zone installation and temperature control are used is to realize each heating region temperature adjustment control.Heating casing 2 is covered by a radial lamella with holes 5 in the face of the one side of glass.But heating casing 2 inside are the spaces of a perforation away from the part of glass, and air can flow therein swimmingly.Under the situation that the heating casing broadens, can set up blowhole and backwind tube between the heating unit 3.For air can circulate swimmingly, the position that each zone of being cut apart by dividing plate 10 joins respectively is provided with one or more backwind tubes 4.A plurality of horizontal heating casings 2 are arranged (as shown in Figure 2) in the vertical.
The utility model is when processed glass, glass 6 is reciprocating on rollgang 7, high-temperature blower 1 blasts air in the heating casing 2, heating unit 3 heating powers can heat by the radial lamella 5 of radiation to the band blowhole, at this moment, can the flow through surface of heating unit 3 of air, wind can be taken away the heat of heating unit 3, and a part of heat is conducted to radial lamella 5, and another part hot blast directly blows to glass 6 by the hole on the radial lamella 5.Simultaneously, radial lamella 5 also can heat glass 6 by radiation, after the surface of glass 6 is crossed in wind, can get back to the top of heating casing 2, be blasted again by high-temperature blower 1 and carry out next one circulation in the heating casing 2 by the slit between backwind tube 4 or the heating casing 2.
This mode of using hot-air convection and radiation that glass is heated has simultaneously shortened heat-up time of glass greatly, has overcome the heating difficulty that the glass rete brings, and has guaranteed to produce required real even heating.
