Problems solved by technology

[0003] After the silicon wafer is printed, it needs to be dried in a drying furnace. The conveyor belt on the existing drying furnace is a roller chain conveyor, which can only place a single silicon wafer, which is extremely inefficient, and the front entrance and the rear exit It is easy to dissipate heat outside the equipment, which affects the internal drying effect

Embodiment 1

[0030] like Figure 1 to Figure 5 As shown, in this embodiment, a drying furnace conveyed by a rolling chain tray includes a conveying flower basket 1, an upper drying area 2 and a lower return area 3, and the front end of the upper drying area 2 and the upper drying area 2 The rear ends are equipped with chain gears 4, and a double-pitch mesh chain 5 is connected to the chain gears 4. The double-pitch mesh chain 5 is provided with a positioning tray 6 and an auxiliary installation piece 7. The auxiliary installation piece 7 is connected with the double pitch. The net chain 5 is integrally formed, the side of the positioning tray 6 is fixedly connected with the auxiliary mounting piece 7, the positioning tray 6 is provided with a positioning column 8, and the bottom of the conveying flower basket 1 is provided with a positioning hole 9, and the positioning column 8 is inserted into the positioning hole 9. The front end of the drying area 2 and the rear end of the upper drying ...

Embodiment 2

[0040] The difference between this embodiment and the first embodiment is that:

[0041] like Figures 6 to 8 As shown, in this embodiment, a nitrogen system 34 ( Figure 8 The direction of the arrow in the middle is the flow direction of nitrogen), and nitrogen is used to protect the silicon wafer. The nitrogen system 34 includes a combustion tower 35, an electronically controlled air valve adjustment switch 36, a nitrogen sampling pipe 37 and a nitrogen injection pipe 38. The furnace part has a nitrogen injection pipe 38, and the part of the nitrogen injection pipe 38 is connected to the interior of the upper drying zone, wherein the front section of the upper drying zone is the isolation zone chamber 39, and the middle section of the upper drying zone is the constant temperature zone chamber 41 and The chamber 40 in the preheating zone, the chamber 42 in the transition zone at the rear of the upper drying zone, and the upper drying zone are equipped with a plurality of set...

Abstract

The drying furnace comprises a conveying basket, an upper-layer drying area and a lower-layer returning area, chain gears are installed at the front end of the upper-layer drying area and the rear end of the upper-layer drying area correspondingly, and a double-pitch net chain is in transmission connection between the chain gears; the double-pitch net chain is provided with a positioning tray and an auxiliary mounting piece, the positioning tray is provided with a positioning column, the bottom of the conveying basket is provided with a positioning hole, the positioning column is inserted into the positioning hole, and the front end of the upper-layer drying area and the rear end of the upper-layer drying area are further provided with heat preservation control doors. According to the drying furnace, the double-pitch network chain is adopted as a conveying structure, the positioning trays are used for conveying the conveying baskets at stable speed and intervals, the front and rear mechanical arms are matched to facilitate taking and placing, the conveying baskets increase the conveying number of silicon wafers, the heat preservation control door can reduce heat loss in the drying furnace, and the drying efficiency is improved. Production energy is saved, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of drying ovens, in particular to a drying oven conveyed by rolling chain trays. Background technique [0002] Photovoltaic solar wafers (hereinafter referred to as silicon wafers) are the core part of the solar power generation system and the most valuable part of the solar power generation system. The role of silicon wafers is to convert solar energy into electrical energy, which is stored by batteries or directly loaded. [0003] After the silicon wafer is printed, it needs to be dried in a drying furnace. The conveyor belt on the existing drying furnace is a roller chain conveying, and only a single silicon wafer can be placed, which is extremely inefficient, and the front entrance and rear exit are It is easy to dissipate heat out of the device, which affects the drying effect inside. SUMMARY OF THE INVENTION [0004] One object of the present invention is to provide a drying oven conveyed by a roll...
