Abstract
An energy-saving sintering furnace structurally comprises a machine frame, a heat preservation cover, a driving wheel, a mesh belt, a thermal insulation layer, radiating elements, exhaust holes, a driven wheel and air inlet holes, and is characterized in that the radiating elements are fixed on a top surface or an inner side surface in a hearth in the heat preservation cover; and the thermal insulation layer is arranged between the heat preservation cover and the hearth. Compared with a sintering furnace adopting a quartz tube as a heating element, the energy-saving sintering furnace has the advantages that the heating radiating elements are not needed to be replaced frequently, the formed sintering furnace has simpler structure, the length is reduced by two thirds, and the investing cost is reduced; and the energy-saving sintering furnace has the characteristics of convenience for maintenance and long service life, saves electricity by 70%, serves as an energy-saving manner in manufacturing solar photovoltaic cells, saves the non-renewable resource, and is in conformity with the national industrial policies.
Description
Technical field
A kind of energy-saving type sintering furnace of the utility model, what relate to is the technical field of photovoltaic cell, is applied to the sintering of silicon chip.
Background technology
At present, the sintering of domestic solar-energy photo-voltaic cell is to utilize the quartz ampoule heating, and its mode of heating is to adopt the sintering process process of the temperature curve of setting from normal temperature-high temperature-normal temperature, and described high temperature is generally about 900 ℃; The length of sintering furnace is not less than 7m as not, and not only consumption is very big aspect the energy, and quartz ampoule is changed quite frequent.In addition, thickness has only the following silicon chip of 0.4mm, and at high temperature easy deformation directly has influence on down road technology, causes silicon chip fragmentation easily when encapsulation, and the conversion efficiency of the solar components of encapsulation is descended; Even the situation that the monoblock solar components is scrapped also happens occasionally, and caused the rising of production cost, increased the cost of investment of solar photovoltaic power plant indirectly, wasted a large amount of resources.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, sintering process to solar-energy photo-voltaic cell production is improved, promptly sintering furnace is improved, utilize ceramic matrix to add elements such as vanadium, titanium and make the alternative quartz ampoule of radiating element, reach a kind of energy-saving type sintering furnace of energy-saving effect as heating element heater.Its technology is achieved in that the structure that comprises frame, stay-warm case, driving wheel, guipure, heat-insulation layer, radiating element, steam vent, follower, air admission hole, it is characterized in that: end face or medial surface in the burner hearth are fixed with radiating element; Be equipped with heat-insulation layer between stay-warm case and the burner hearth.The obvious advantage of implementing after this technology with effect is: compare with the sintering furnace that utilizes quartz ampoule to make heater element, this energy-saving type sintering furnace need not often to change to add hot radiant element, the sintering furnace structure that forms is simple relatively, and foreshortened length 2/3 has reduced cost of investment, have easy to maintenance, the evident characteristic of long service life, economize on electricity 70% is a kind of power save mode that solar-energy photo-voltaic cell is produced, save non-renewable resources, met the industrial policy of country.
Description of drawings
Fig. 1 looks the sectional structure schematic diagram for master of the present utility model;
Wherein, 1-frame, 2-stay-warm case, 3-driving wheel, 4-guipure, 5-heat-insulation layer, 6-radiating element, 7-steam vent, 8-follower, 9-air admission hole, 10-burner hearth, 11-silicon chip.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
See accompanying drawing 1, be fixed with stay-warm case 2 on the frame 1, be equipped with heat-insulation layer 5 between stay-warm case 2 and the burner hearth 10; Frame 1 two ends are respectively equipped with driving wheel 3 and follower 8, and driving wheel 3 one ends link to each other with reducing motor; Be provided with the guipure 4 that passes burner hearth 10 between driving wheel 3 and the follower 8 and form carrier chain, burner hearth 10 end faces are fixed with radiating element 6; Stay-warm case 2 upsides have the steam vent 7 that is communicated with burner hearth 10 vestibules, and stay-warm case 2 downsides have the air admission hole 9 that is communicated with burner hearth 10 vestibules.
See accompanying drawing 1, the whole operation system is controlled by computer, radiating element 6 is connected power supply, radiating element 6 is heated and radiation wavelength is a 700um all-wave far infrared, start reducing motor and drive driving wheel 3 rotations, driving wheel 3 drives guipure 4 and is moved to driving wheel 3 directions by follower 8, guipure 4 drives silicon chip 11 motions that are printed with aluminium paste on the guipure 4 thereupon, through radiating element 6 time, heated radiating element 6 is that the infrared direct irradiation of 700um all-wave is on silicon chip 11 with radiation wavelength, sintering is carried out on bonding silicon chip 11 surfaces of oven dry and activation and aluminium paste, the adhesive surface of aluminium paste and silicon chip 11 is bonded into one securely, take out of by the guipure 4 in the motion again, good by silicon chip 11 contacts of this method sintering, increased electric conductivity.Steam vent 7 is got rid of waste gas in the sintering furnace by pulling out wind, when needs are protected silicon chip 11 sintering with protective gas, opens air admission hole 9 and enters protective gas in right amount.
Equally, the silver of printing slurry is adopted to use the same method and is dried and sintering on the silicon chip 11, and in addition, net belt type dryer employing radiating element 6 also within this patent coverage.
