DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] like Figure 1 , Figure 2 , Figure 4 As shown, a cell connecting furnace comprises a furnace body 1 and a furnace cover 2. A double-layer conveying mechanism 3 is horizontally arranged in the furnace body 1. A plurality of heating tubes 4 are arranged side by side below the double-layer conveying mechanism 3. A plurality of heating tubes 4 are also arranged side by side in the furnace cover 2. A plurality of blowing tubes 5 are vertically inserted at the bottom of the furnace body 1 and the top of the furnace cover 2.

[0020] The connecting furnace is mainly used for conveying photovoltaic cells and drying the photovoltaic cells during the conveying process. A double-layer conveying mechanism 3 is designed in the furnace, which can convey photovoltaic cells on the upper and lower layers at the same time, thereby improving the conveying efficiency; and the heating pipes 4 are respectively arranged on the upper and lower sides of the double-layer conveying mechanism 3, so that the photovoltaic cells are heated on both sides, the drying speed is faster, and the effect is better; the upper and lower air blowing pipes 5 are arranged, which can not only make the heat evenly distributed, but also can adjust the temperature in the furnace.

[0021] like Figure 2 , Figure 3 As shown, the double-layer conveying mechanism 3 includes two upper rail plates 31 and two lower rail plates 32 that are symmetrical on both sides. An upper slide rail 33 and a lower slide rail 34 are fixedly connected to the upper rail plate 31 and the lower rail plate 32, respectively. A conveying chain 35 is slidably connected to the upper slide rail 33 and the lower slide rail 34, and a bearing rod 36 is fixedly connected between the conveying chains 35.

[0022] The conveyor chain 35 slides on the upper slide rail 33 and the lower slide rail 34, which is easy to manufacture and durable; the bearing rods 36 can provide fixed support for the conveyor chains 35 on the left and right sides to ensure that the chains do not derail; there is a spacing between the bearing rods 36, which can make the heat radiation in the furnace more uniform and reduce the obstruction of the dried objects.

[0023] like Figure 3 As shown, the upper slide rail 33 and the lower slide rail 34 are both double-track slide rails, and the conveying chain 35 is a double-row chain with ears; the double-row design can increase the contact area between the slide rail and the conveying chain 35, making its sliding more stable.

[0024] like Figure 3 As shown, a plurality of carrying rings 37 are sleeved on the carrying rods 36. The carrying rings 37 can reduce the contact area between the photovoltaic cells and the double-layer conveying mechanism 3, and at the same time form a gap between the photovoltaic cells and the carrying rods 36, which helps to increase the drying speed and reduce damage to the surface of the photovoltaic cells.

[0025] like Figure 4 As shown, a heat-insulating layer 12 is attached to the furnace body 1 and the furnace cover 2, which can improve the heat-insulating effect of the furnace and save electric energy.

[0026] like Figure 4 As shown, a filter cover 51 is provided at the mouth of the air blowing pipe 5 to prevent large particles from entering the furnace and damaging the photovoltaic cells.
