Abstract
The utility model discloses a heating furnace, which comprises an upper furnace body, a lower furnace body, and a conveying roller way which is formed in the middle and is used for conveying a heated glass plate, wherein two ends of the furnace bodies are provided with furnace doors, an inner wall of the top of the upper furnace body is provided with an upper heating unit, an inner wall of the bottom of the lower furnace body is provided with a lower heating unit, and the upper heating unit and the lower heating unit respectively comprise a plurality of heating modules which are arranged in a matrix mode; and the heating furnace is characterized in that the size of power of the heating modules can be set according to areas and can be adjusted. Compared with the prior art, the heating furnace has the advantages that the power of a plurality of heating modules which are divided by the upper heating unit and the lower heating unit and are arranged in the matrix mode can be adjusted according to areas and can be independently adjusted, so that the heating power of different sizes can be applied to different areas in the furnace cavity, the energy efficiency ratio of the heating furnace and the heating quality of the glass plate are improved, and the operating cost is reduced.
Description
Technical field
The utility model relates to glass plate heating furnace, particularly a kind of matrix form process furnace.
Background technology
The process furnace of present matrix form heating layout adopts the distribution form of each heating zone equipower, and power averaging distributes.And the heat-processed of glass; Because the display case of glass is different: in the middle of general glass is arranged and all around or two ends do not have glass, and each position heat absorption condition of every sheet glass is different: periphery is easy to heating, the centre is difficult to heating, often each zone caloric receptivity and inhomogeneous; It is higher that the structure formation that heating power originally is evenly distributed has produced interior some regional temperature of stove; And some regional temperature heats the defective that do not get on, both has been unfavorable for the heating of glass, has also wasted the energy.
The utility model content
For addressing the above problem, the utility model distributes according to different zones power to the different demands that add heat, and process furnace two ends or whole peripheral heating region heating power reduce; And the region intermediate heating power strengthens; Strengthen the intensity of middle part, reduce periphery, particularly two ends heating intensity glass heats; Paying of so actual heat-processed power will more become reasonable; Actual being heated of glass also will be more even, and the glass tempering stress distribution will be more even also, thereby improve the quality of glass tempering.
A kind of process furnace of the utility model; What comprise that top body of heater, bottom body of heater and middle part be provided with is used to carry the rollgang that is heated sheet glass, and the body of heater two ends are provided with fire door, and the top inner wall of top body of heater is provided with the top heating unit; The bottom interior wall of bottom body of heater is provided with the lower heating unit; Top heating unit and lower heating unit comprise that respectively several are arranged as the heating module of matrix, it is characterized in that, the power of said heating module can be provided with different sizes by the zone and can regulate.
Further, the power of said heating module is set to from periphery to the intermediary power gradient by the zone.
Further, it is big that said power gradient is set to middle power, and peripheral power is little.
Further, the power of said heating module can be allocated separately, the power configuration that control more accurately needs.
Further, the arranged of said heating module be m capable * n row, m >=2, n >=1, and m, n be natural number, and set the direction parallel with being heated the sheet glass traffic direction and be row and is heated the vertical direction of sheet glass traffic direction for being listed as.
After the utility model is joined the adjustable power of the heating module of some arranged of top heating unit and lower heating dividing elements; Realized that the different zones in furnace chamber can apply different heating powers; Both can when heating pieces of glass plate, only start the heating module corresponding with glass sheet size; Can when heating structural glass plate, regulate the heating heat that each heating module imposes on the sheet glass different sites respectively again; For example the heating module power of region intermediate is transferred big and the heating module power of areas at both sides is turned down, guarantees the homogeneity that sheet glass is heated; Can also close heating module in the zone after sheet glass moves, reduce running cost.Therefore, the utility model has improved the EER of process furnace, and then has improved the heating quality of sheet glass, has also reduced running cost.
Description of drawings
Fig. 1 is the utility model heating furnace structure synoptic diagram;
Fig. 2 is the vertical view of the utility model process furnace;
Wherein: 1 top heating unit, 2 top bodies of heater, 3 fire doors, 4 rollgangs, 5 bottom bodies of heater, 6 lower heating unit, 7 heating modules.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of process furnace of the utility model; As depicted in figs. 1 and 2; What comprise that top body of heater 2, bottom body of heater 5 and middle part be provided with is used to carry the rollgang 4 that is heated sheet glass; Top body of heater 2 is provided with fire door 3 with the two ends of bottom body of heater 5, and the top inner wall of top body of heater 2 is provided with top heating unit 1, and the bottom interior wall of bottom body of heater 5 is provided with lower heating unit 6; Top heating unit 1 comprises several heating modules that is arranged as matrix 7 respectively with lower heating unit 6, and the power of said heating module 7 can be provided with different sizes by the zone and can regulate.
Said heating module 7 can be provided with the certain power gradient in the centre from the periphery of process furnace to process furnace; Obtain more heating heat so that be heated the position that the centre of sheet glass is difficult to heat; And the position that the periphery that is heated sheet glass is easy to heat obtains the heating heat that lacks some slightly; But the power gradient that the periphery that it should be noted that process furnace is provided with in the middle of the process furnace should be not excessive, and is excessive with the middle part heating of avoiding occurring being heated sheet glass; And the peripheral position that is heated sheet glass does not also have enough situations of heating; The said certain power gradient that from the periphery to the centre, is provided with is meant that the power of process furnace periphery setting is little simultaneously, and the middle power that is provided with is big.
For satisfying other demands that are heated sheet glass; Also be heated sheet glass at the different needed different capacities constantly of different sites in order further accurately to control; The power of each heating module 7 of the utility model also can be allocated separately, can be in difference allotment at any time constantly.
Although a surface is provided with 5 * 5 matrix form in the process furnace shown in Fig. 2; But the heating module on the utility model process furnace surface is arranged and is not limited to this, the arranged of said heating module be m capable * the n row, m >=2; N >=1; And m, n are natural number, and set the direction parallel with being heated the sheet glass traffic direction for going, and are row with being heated the vertical direction of sheet glass traffic direction.
The process furnace of the utility model is provided with the power of heating module through adjustable matrix form, can produce different heating heats in different zones; Help satisfying the sheet glass demand for heat of particular requirement, help accurate control, and can select different heat protocol according to the different size that is heated sheet glass to Heating temperature; The utility model is simple in structure; Improve the EER of process furnace, and then improved the heating quality of sheet glass, also reduced running cost.
The person of ordinary skill in the field should know, in any pro forma change of on the basis of the utility model design the utility model being made or revise all in the protection domain at the utility model.
