Abstract
The utility model provides a convection oven of a glass plate heating furnace. The convection oven comprises air bellows and convection oven covers, wherein the air bellows are communicated with the convection oven covers via air outlets; guiding devices for guiding airflow in the air bellows to the air outlets are arranged at the corners of the airflow in the air bellows; each guiding device comprises one or a plurality of guide plates arranged in parallel and at uniform intervals. By virtue of the convection oven, the airflow in the air bellows flows smoothly along the flow direction, so that the air pressure loss is effectively reduced and then the efficiency of convection heating of glass plates can be improved under the condition that the fan power is not increased and energy can be saved.
Description
Technical field
The utility model relates to a kind of glass plate heating furnace, especially relates to a kind of glass plate heating furnace convection current case.
Background technology
In convective glass sheet heating furnaces, conventionally will use a kind of convection current case, described process furnace has upper furnace body and lower furnace body, is provided with glass sheets roller-way between upper furnace body and lower furnace body,
Described convection current case comprises bellows and convection current case cover, and the air outlet of bellows is connected with convection current case cover, in convection current case cover, is provided with well heater.When work, under the effect of blower fan, air-flow blows to convection current case cover from the air outlet of bellows, through the heating of well heater, then blows to sheet glass, and sheet glass is heated.In prior art, the existing structure of convection current case makes gas flow pressure loss large, and each portion pressure is unbalanced, not only affect the homogeneous heating of sheet glass, and heating efficiency is low.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of glass plate heating furnace convection current case, can make flowing of air-flow more smooth and easy, effectively reduces air loss, improves the heating efficiency to glass.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of glass plate heating furnace convection current case, comprise bellows and convection current case cover, and the air outlet of bellows communicates with convection current case cover, is provided with the guiding device that air-flow is led in bellows.
Further, described guiding device is made up of one or more spaced flow deflector.
Further, described multiple flow deflectors are arranged in parallel.
Further, described multiple flow deflector each intervals evenly arrange.
Further, described flow deflector is smooth plate.
Further, described flow deflector is arc.
Further, described air outlet is two.
Beneficial effect:
The utility model increases guiding device in the bellows of convection current case, can make the air-flow in bellows mobile more smooth and easy along mobile direction, effectively reduce air loss, in the situation that not increasing power of fan, can improve the efficiency to sheet glass convective heating, and can save energy.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to further concrete detailed explanation.
Fig. 1 is a kind of exemplary plot that a kind of glass plate heating furnace of the utility model convection current case is installed and used.In figure, process furnace has upper furnace body 8 and lower furnace body 6, between upper furnace body 8 and lower furnace body 6, be provided with glass sheets roller-way 4, convection current case comprises bellows 2 and convection current case cover 7, bellows 2 are connected with the convective cover 7 of convection current case by air outlet 9, in convection current case cover 7, be provided with well heater 3, under the effect of blower fan 1, air-flow blows in convection current case cover 7 from the air outlet 9 of bellows 2, after the heating of well heater 3, blow to sheet glass, sheet glass 5 is heated, then be back to bellows 2 through the blast inlet of bellows 2, so convection circulation is carried out convective heating to sheet glass 5.
Fig. 2 is bellows 2 structural representations in the utility model, as shown in Figures 2 and 3, be respectively equipped with one opens to the air outlet 9 in convection current case cover at the two ends of bellows 2, (because bellows are symmetrical structure, in figure, only demonstrated one of them air outlet, the position of another air outlet can be found out in the usage example shown in Fig. 1.) described bellows 2 are connected with convection current case cover 7, on connection wind path, there is turning, air channel, around the corner, front side wall 13 and rear wall 12(front and back mentioned herein, and the same meaning up and down shown in Fig. 3) between be provided with the mobile guiding device that guides and shunt to gas.
The present embodiment guiding device is the flow deflector 10 of multiple arcs.And multiple flow deflector 10 shapes are identical and apart from one another by evenly, be arranged in parallel.
Flow deflector 10 also can only arrange one according to practical situation, and described multiple flow deflectors 10 can be also other shapes such as being dull and stereotyped, and each interval can be also inhomogeneous, even uneven also passable.Such as flat board forms square or leg-of-mutton gas channel each other.
Described guiding device also can be arranged on the bend pipe the same with end arc bent plate 11 radians of air channel corner, in a word as long as playing to gas mobile the effect of guiding and shunting, within the scope all comprising in this design.
The structure of bellows 2 can be the structure of any applicable installation guiding device in prior art.
Guiding device also can be located at arbitrary suitable position in the passage of gas communication in bellows.The structure of the structure of guiding device and shape and this correct position matches.
