Abstract
The utility model provides a heating device for an annealing furnace, which comprises a furnace body and a ceramic roller arranged on the middle of the furnace body, wherein a jet flow type forced convector is arranged between the furnace body and the ceramic roller; one side of the jet flow type forced convector close to the ceramic roller is provided with a cover plate; a refractory brick having a thermal fuse is arranged inside the cover plate; and the top of the jet flow type forced convector is provided with a convector fan. The heating device of the utility model can heat uniformly and speedily through convection heat, the wind loss is small, the energy is saved and the structure is simple.
Description
Technical field:
The utility model relates to a kind of glass working machine, especially a kind of glass tempering furnace heating unit.
Background technology:
In the prior art, technique known is that the process furnace of traditional glass tempering unit partly adopts the radiation heating technology, mainly from the thermal radiation of heating unit, the heat of lower glass surface comes from the thermal conduction of ceramic roller and the thermal radiation of lower heating element to the heat that surface on glass absorbed; Along with appearance and the widespread use of LOW-E coated glass in market, traditional radiation furnace can not satisfy the needs of LOW-E glass heats, tempering; Rete can go back a large amount of reflect radiation heat at last LOW-E glass, have only small amount of radiation heat to pass the glass rete, play the effect of heating glass, like this glass be heated inhomogeneous, cause the various defectives of glass easily, this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of technical scheme of glass tempering furnace heating unit is provided, and the heating unit of this scheme adopts convective heating, homogeneous heating, and speed is fast; The wind path loss is little, energy-conservation; And it is simple in structure.
This programme is realized by following technical measures: a kind of glass tempering furnace heating unit, include body of heater, be arranged on the ceramic roller at body of heater middle part, the characteristics of this programme are: be provided with jet flow forced convection device between described ceramic roller and body of heater, described jet flow forced convection device is provided with cover plate near a side of ceramic roller, the cover plate inboard is provided with the refractory brick that has heating wire, and the top of described jet flow forced convection device is provided with convection flow fan.Be provided with a plurality of backwind tubes in the jet flow forced convection device, an end of described backwind tube is arranged between convector cover plate and the refractory brick, and the other end is arranged between convector and the body of heater.
The beneficial effect of this programme can learn according to the narration to such scheme, owing in this scheme, be provided with jet flow forced convection device in the both sides of ceramic roller, and can be to the upper surface of glass and lower surface even heating rapidly simultaneously; Be provided with the refractory brick that has heating wire in the convector, can provide heat to heating glass, be provided with convection flow fan in the convector, to the glass convective heating, though the LOW-E rete has obstruct to radiant heat, but very little to the convective heating iris action, so convection flow fan can finely utilize hot blast that glass is heated, in addition, the bottom and the top of backwind tube penetrative convection device, the heat recuperation that can will not be utilized heats glass again to convection flow fan.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1 is ceramic roller, and 2 is the convector cover plate, and 3 is refractory brick, and 4 is heating wire, and 5 is body of heater, and 6 is jet flow forced convection device, and 7 is backwind tube, and 8 is convection flow fan.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.
By accompanying drawing as can be seen, the glass tempering furnace heating unit of this programme, include body of heater 5, be arranged on the ceramic roller 1 at body of heater 5 middle parts, the characteristics of this programme are: be provided with jet flow forced convection device 6 between described ceramic roller 1 and body of heater 5, described jet flow forced convection device 6 is provided with cover plate 2 near a side of ceramic roller 1, and cover plate 2 inboards are provided with the refractory brick 3 that has heating wire 4, and the top of jet flow forced convection device 6 is provided with convection flow fan 8.Be provided with a plurality of backwind tubes 7 in the jet flow forced convection device 6, an end of backwind tube 7 is arranged between convector cover plate 2 and the refractory brick 3, and the other end is arranged between convector 6 and the body of heater 5.
