Abstract
The invention provides a heating device of a drying area of a solar cell sintering furnace. A heating unit can be firmly arranged in a hearth of the drying area, and at the same time, adopted heating tubes are beneficial for achieving the temperature curve of drying of the drying area. The heating device comprises two conveying guide rails arranged in parallel and a conveying mesh belt which is arranged between the conveying guide rails and used for conveying solar cells to be sintered, the heating device further comprises an upper hearth arranged above the conveying guide rails and a lower hearth arranged below the conveying guide rails, the upper hearth and the lower hearth are symmetrically arranged, and the upper hearth comprises three upper hearth sealing connection segments in different temperature areas, the lower hearth comprises three lower hearth sealing connection segments in different areas, and the upper hearth sealing connection segments and the lower hearth sealing connection segments are symmetrically arranged. The heating tubes are arranged in the upper hearth and the lower hearth. The heating tubes are infrared quartz burners, and the quartz burners are medium-wave tubes. The two ends of each heating tubes are fixed to the side walls of the hearths. Hanging clamps used for hanging and fixing the heating tubes are further arranged on the heating tube, one ends of the hanging clamps are arranged on the heating tubes in a sleeved mode, and the other ends of the hanging clamps are fixedly arranged on the inner walls of the hearths.
Description
Technical field
The present invention relates to the production equipment of solar battery sheet, be specifically applied to the stoving process before solar battery sheet sintering.
Background technology
Along with popularizing of solar cell power generation, the demand of solar battery sheet increases, also increasing as visual plant-solar battery sheet sintering furnace demand and the use amount of producing solar battery sheet, solar battery sheet sintering furnace often will be realized failure-free operation in several months, therefore the power consumption of sintering furnace is quite large, is mainly reflected in heating tube in the heating of warm area.
Sintering furnace is generally divided into three warm areas, baking zone, sintering zone and cooling zone, because multiple heating tubes are arranged on burner hearth inside, in the time of fixing not firm of heating tube, in the time of long-term use, easily produce and become flexible, this situation, by causing the sintering of sintering furnace and the process curve of oven dry to change, affects product quality.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of heater of baking zone of solar battery sheet sintering furnace is provided, this firm burner hearth inside that is arranged on baking zone of heating unit energy, meanwhile, the heating tube of use is more conducive to realize the temperature curve that baking zone is dried.
The technical solution adopted for the present invention to solve the technical problems is: a kind of heater of baking zone of solar battery sheet sintering furnace, comprise between two transmission guide rail be arrangeding in parallel and setting and transmission guide rail for transmitting solar battery sheet to be sintered;
Also comprise the upper furnace that is arranged at above-mentioned transmission guide rail top and the lower hearth that is arranged at transmission guide rail below; Upper lower hearth is symmetrical arranged, and described upper lower hearth comprises that the symmetrical upper lower hearth of installing of three of different warm areas is tightly connected;
Heating tube is installed on lower hearth inside;
Above-mentioned heating tube is infrared quartz fluorescent tube, and described infrared quartz fluorescent tube is middle wave duct;
The two ends of above-mentioned heating tube are fixed on by set bolt on the sidewall of burner hearth; On heating tube, be also provided with for heating tube being hung to fixing suspension clamp, suspension clamp one end is sleeved on heating tube, and the other end is fixedly mounted on inboard wall of burner hearth.
Further: on the inwall of above-mentioned burner hearth, also hang and be provided with thermocouple.
Further: upper and lower two thermocouples of the built-in layout of the each warm area of above-mentioned thermocouple, upper and lower two thermocouples lay respectively at lower hearth bosom position, and thermocouple vertically arranges.
The invention has the beneficial effects as follows:
The heating unit of the baking zone of solar battery sheet sintering furnace of the present invention, heating tube adopts the infrared quartz fluorescent tube that more can realize baking zone temperature curve, and this infrared quartz fluorescent tube is middle wave duct; Meanwhile, heating tube two ends are fixed by suspension clamp in burner hearth inside, make whole heating tube fixing very firm, can the not exert an influence change in location of temperature curve of long-term use; Finally, whole burner hearth inside also hangs the thermocouple being provided with for measuring burner hearth internal temperature, has guaranteed to understand in real time the temperature information of baking zone.
