Description

Technical Field

[0001] This application relates to the field of perovskite photovoltaic technology, and in particular to an annealing furnace conveyor belt device with a maintenance window. Background Technology

[0002] Annealing furnaces are widely used in current industrial production. In the perovskite photovoltaic industry, annealing furnaces typically use heating tubes, consisting of upper and lower heating tubes. The upper heating tube is mounted on a conveyor belt, while the lower heating tube is installed below it. The product is fed into the annealing furnace chamber by the conveyor belt and heated by the upper and lower heating tubes. The conveyor belt itself is a closed, annular structure, providing continuous circulation. Figure 5 As shown, the conveyor belt structure resembles a tank track, being a ring-shaped belt connected by metal chains on both sides. Transmission relies on gears meshing with the chains for power. A mesh belt, woven from metal, connects the two chains and is linked to the chains by several support rods perpendicular to the chains. These support rods pass through the mesh belt and are connected to the metal chains at both ends. When the lower heating element malfunctions and requires replacement or maintenance, the lower heating element is completely encased in the ring-shaped conveyor belt, leaving no space for direct operation. The conveyor belt chain and metal mesh must be disassembled before any work can be done. However, due to the considerable length and weight of the entire conveyor belt, disassembly and subsequent reassembly are extremely complex and laborious, severely impacting the difficulty and time required for maintenance within the conveyor belt. Utility Model Content

[0006] The mesh belt is disposed between the two chains;

[0007] There are multiple support rods, which are arranged in a direction perpendicular to the chain, and the support rods pass through the mesh belt and are fixedly connected to two chains;

[0008] At least one of the support rods adopts a three-section combined structure and is detachably connected by the coupling.

[0009] In one possible implementation, the coupling includes a left coupling and a right coupling;

[0042] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0043] Figure 1 A schematic diagram of the main structure according to an embodiment of this application is shown. Figure 1 As shown, the annealing furnace conveyor belt device with maintenance window according to this application embodiment includes: chain 140, mesh belt, support rod 110 and coupling 130. The chain 140 is a closed ring structure, and there are two chains 140. The mesh belt is arranged between the two chains 140. There are multiple support rods 110. The multiple support rods 110 are arranged in a direction perpendicular to the chain 140, and the support rods 110 pass through the mesh belt and are fixedly connected to the two chains 140. At least one support rod 110 adopts a three-section combined structure and is detachably connected by coupling 130.

[0044] It should be noted that the heating element consists of two parts: an upper heating element mounted on the conveyor belt and a lower heating element mounted below it. The product is fed into the annealing furnace chamber by the conveyor belt and heated by the upper and lower heating elements. The conveyor belt itself is a closed, ring-shaped structure that circulates the product.

[0045] In this embodiment, the annular conveyor belt device is designed with a window that can be easily opened or assembled. When needed, maintenance of components such as the heating pipes inside the annular conveyor belt can be performed quickly and easily through this window, greatly reducing the difficulty of the work and saving maintenance time. Specifically, at least one support rod 110 adopts a three-section combined structure and is detachably connected by a coupling 130, allowing for quick installation and removal of at least one support rod 110, completing the opening and closing of the window, and facilitating maintenance and replacement.

[0046] In one specific embodiment, the coupling 130 includes a left coupling 131 and a right coupling 132. The structure of the left coupling 131 is the same as that of the right coupling 132, and the left coupling 131 and the right coupling 132 are detachably connected. By bolting the left coupling 131 and the right coupling 132 together, the support rod 110 of the three-section combined structure can be quickly installed and disassembled.

[0047] In one specific embodiment, the left coupling 131 has a shaft hole 1313 and a screw hole 1314. The shaft hole 1313 is oriented in the same direction as the screw hole 1314, facilitating bolt connection between the left coupling 131 and the right coupling 132. The shaft hole 1313 matches the end of the support rod 110, which is embedded in the shaft hole 1313, thus fixing the support rod 110 to the coupling 130. The screw hole 1314 is a through hole, allowing a single bolt to be used to bolt the left coupling 131 and the right coupling 132 together. This allows the end of the support rod 110 to be easily embedded in the shaft hole 1313 and fixed via the screw hole 1314, enhancing the connection strength between the support rod 110 and the coupling 130.

[0048] In one specific embodiment, the left coupling 131 includes a coupling body 1311 and a fixing part 1312. The coupling 130 has a cylindrical structure, with a shaft hole 1313 located at the middle of one end of the coupling body 1311. The fixing part 1312 is disposed on the outer wall of the coupling body 1311, arranged circumferentially along the coupling 130, and a screw hole 1314 is located on the fixing part 1312. The fixing part 1312 is integrally formed with the coupling body 1311, with the shaft hole 1313 located on the coupling body 1311 and the screw hole 1314 located on the fixing part 1312. This allows the coupling body 1311 to be fixedly connected to the end of the support rod 110 through the shaft hole 1313, and the fixing part 1312 to be bolted to the screw hole 1314 of the other fixing part 1312.

[0049] Furthermore, in this specific embodiment, a plurality of screw holes 1314 are arranged at circumferential intervals along the fixing part 1312 to further enhance the connection stability of the left coupling 131 and the right coupling 132.

[0050] In one specific embodiment, the fixing part 1312 is annular and located at the end of the coupling body 1311 away from the shaft hole 1313. When the left coupling 131 and the right coupling 132 abut, the fixing part 1312 of the left coupling 131 abuts against the fixing part 1312 of the right coupling 132, and the screw hole 1314 of the left coupling 131 corresponds to the screw hole 1314 of the right coupling 132. The annular fixing part 1312 can have multiple screw holes 1314 in the circumferential direction, so that the left coupling 131 and the right coupling 132 are stably connected.

[0051] In one specific embodiment, a through-hole 1315 is provided on the coupling body 1311. The opening direction of the 1315 is perpendicular to the opening direction of the shaft hole 1313, and the 1315 communicates with the shaft hole 1313. The 1315 provides an additional fastening means, and when needed, the connection between the support rod 110 and the coupling body 1311 can be further strengthened by the 1315, thereby improving the stability and safety of the equipment.

[0052] In addition, multiple set screw holes 1315 can be equally spaced along the circumference of the coupling body 1311 to fix the end of the support rod 110 embedded in the shaft hole 1313.

[0053] In one specific embodiment, a fixing buckle 120 is also included, and both ends of the support rod 110 are fixedly connected to the chain 140 through the fixing buckle 120. The support rod 110 has a three-section combined structure, and both ends of it are fixed to the chain 140 through the fixing buckle 120.

[0054] In one specific embodiment, the coupling 130 has an interference hole 1316, the opening direction of which is the same as that of the shaft hole 1313. The interference hole 1316 communicates with the shaft hole 1313, and the interference fit provides a channel for fastening the coupling body 1311 to the end of the support rod 110. When needed, the interference fit can further enhance the connection between the support rod 110 and the coupling 130, improving the stability and safety of the equipment.

[0055] In one specific embodiment, there are multiple couplings 130, which enable the opening or closing of the window while ensuring overall support.

[0056] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
