Abstract
The utility model discloses a glass plate heating furnace. The glass plate heating furnace comprises a furnace body, wherein a glass plate conveying roll table is arranged in the furnace body; a plurality of convection boxes arranged in the proceeding direction of a glass plate are arranged above the conveying roll table and/or below the conveying roll table; a plurality of heating units are arranged in each convection box in the axial direction of the conveying roll table; each heating unit comprises a plurality of mutually-tandem helicoidal heating elements; the helicoidal heating elements arranged on a plane parallel to the surface of a glass plate to be conveyed are arranged at intervals and are parallel to one another; the axial lines of the helicoidal heating elements are inclined relative to the proceeding direction of the glass plate. Compared with the prior art, the glass plate heating furnace can realize the full covering of the glass plate with the hot air streams, which are blown out from the convection boxes, in the proceeding direction of the hot air streams, so that the heating of the glass plate can be more uniform.
Description
Technical field
The utility model relates to a kind of for sheet glass tempering heating unit, specially refers to a kind of glass plate heating furnace.
Background technology
As shown in Figure 1, in existing convection type glass fibre reinforced plastic equipment, heating unit 10 is arranged on convection current case inside along the direction parallel with sheet glass direct of travel A conventionally, although this equipment can be realized by the mode of convection current the heating of sheet glass, but the defect obviously existing is, regional temperature between single heating unit is relatively low, is unfavorable for realizing the homogeneous heating of sheet glass, so affect sheet glass toughening process stress evenly.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of brand-new glass plate heating furnace, sheet glass is heated more even, thereby provides safeguard for the toughened glass of production high-quality.
For achieving the above object, a kind of glass plate heating furnace of the utility model comprises and in body of heater, body of heater, is provided with glass sheets roller-way, rollgang top and/or below are provided with several convection current casees of arranging along sheet glass direct of travel, in described convection current case, be placed with several heating units along conveying roller axis direction, each heating unit includes several spirrillum heating units being mutually connected in series, and spirrillum heating unit is spaced at and is parallel in the plane that is transferred glass pane surface and is parallel to each other; The relative sheet glass direct of travel of axis of described spirrillum heating unit is obliquely installed.
Further, be arranged with convection current case described in several along described conveying roller axis direction simultaneously.
Further, each described heating unit is all independently controlled.
Further, described heating unit is arranged on the airflow circulation loop in described convection current case, and the high temperature gas flow after being heated flows to glass pane surface and it is heated.
Further, described convection current case is symmetrical arranged up and down in described body of heater.
The utility model is set to become a set angle with sheet glass direct of travel by heating unit, and described set angle is enough to make the two ends of adjacent two heating units on sheet glass direct of travel, join or partly overlap.And then make the hot gas flow that convection current case blows out reach completely and cover at sheet glass direct of travel, thereby make its heating more even; In addition, separate setting and control between each heating unit, realized temperature and independently regulated, and is more conducive to the even of the interior each several part temperature of stove, save energy.

Fig. 2 is the utility model glass heating furnace structural representation;
Fig. 3 is the utility model glass heating furnace sectional view of bowing;

Fig. 5 is the laying schematic diagram of the utility model heating unit in the vertical direction of sheet glass motion.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 2-5, a kind of glass plate heating furnace of the utility model comprises the rollgang 30 that is provided with conveying sheet glass 60 in body of heater 20, body of heater 20, rollgang 30 above and belows are provided with several convection current casees 40 of arranging along sheet glass direct of travel, convection current case 40 is interior is placed with several heating units 80 along conveying roller axis direction, each heating unit 80 includes several spirrillum heating units 50 being mutually connected in series, and spirrillum heating unit 50 is spaced at and is parallel in the plane that is transferred glass pane surface and is parallel to each other; The relative sheet glass direct of travel of axis of spirrillum heating unit 50 is obliquely installed.
In addition, in the time that process furnace is larger along the size perpendicular to sheet glass direct of travel, when a convection current case is difficult to cover completely, can be arranged with several convection current casees along conveying roller axis direction simultaneously.
Several heating units 50 in heating unit 80 are connected in series mutually.Heating unit 80 is arranged on the airflow circulation loop in convection current case 40, and the high temperature gas flow after being heated flows to glass pane surface and it is heated.
Separate between heating unit 80 in convection current case, be connected with power supply respectively, and separate control each other, and then realize different heating cell temperature independent adjusting just in heating furnace body.
In addition, the quantity that forms the heating unit 50 of heating unit 80 can or design according to actual production and need to be increased and decreased.Convection current case also can be laid for rollgang asymmetric; As the top of rollgang arranges convection current case, sheet glass is carried out to convection type heating, below arranges radiant heating device, and sheet glass is carried out to radiation heating.
Preferably, in heating unit 50, the axis of spirochete part becomes a set angle with sheet glass direct of travel, and set angle is enough to make the vertical projection of adjacent two heating units in institute's heating glass plate plane close or join.The benefit so arranging is, while avoiding that interval is excessive between heating unit, even if heating unit tilts to some extent, also can have also certain dark space, can not reach completely and the object covering; If in one timing of the interval of heating unit, if angle of inclination is excessive, can cause the appearance partial stack of two adjacent heating units on sheet glass direct of travel, and then cause subregion excess Temperature phenomenon simultaneously.Certainly, excessively do not affecting under the inhomogeneity prerequisite of Heating temperature, the vertical projection of adjacent two heating units 50 in institute's heating glass plate plane can partly overlap.
When work, sheet glass enters and passes through heating furnace body along direction A, and heating unit heats air-flow, convection current case the air-flow after heating is blowed on sheet glass and to heating.Be set to become a set angle with sheet glass direct of travel by heating unit, and then make the hot gas flow that convection current case blows out reach completely and cover at sheet glass direct of travel, thereby make its heating more even.
