Description

Technical Field

[0001] This utility model relates to the field of airflow guidance technology, and in particular to an airflow guidance structure inside an aging furnace. Background Technology

[0002] The aging furnace is a key piece of equipment for the final heat treatment of aluminum profiles and sheets. Its working principle is to drive hot air to circulate in the furnace by a blower on the top of the furnace. The guide tube suspended in the center of the furnace is the core airflow organization component, which can guide the hot airflow to evenly wash the workpiece from top to bottom, ensuring the uniformity and stability of product performance.

[0003] To prevent debris from entering the blower and avoid impeller wear, jamming, and other malfunctions, as well as to prevent operators from accidentally touching rotating parts during maintenance, a protective net is installed at the port of the guide tube. Over time, dust and other debris gradually adhere to the protective net and clog the mesh, requiring staff to periodically remove and clean it. However, since the protective net is fastened to the guide tube with multiple bolts, disassembly requires special tools and is often time-consuming. Therefore, we propose an airflow guiding structure for the aging furnace to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flow guiding structure for the internal airflow of an aging furnace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An airflow guiding structure for an aging furnace includes a guide cylinder. A connecting ring is fixedly connected to the end of the guide cylinder, and the connecting ring has holes equidistantly spaced inside. The holes are fixed to the furnace wall by bolts. A protective net is distributed on the inner side of the connecting ring, and a connecting block is fixedly connected to the outer side of the protective net. The connecting block is inserted into a docking groove, and the docking groove is opened inside the fixed block. The side of the fixed block is fixedly connected to the connecting ring. A crossbar is inserted inside the fixed block, and a connecting plate is fixedly connected to the end of the crossbar. A fixing groove adapted to the crossbar is opened inside the connecting block.

[0006] In this device, by setting up connecting blocks and docking grooves, when it is necessary to disassemble the protective net, the cooperation between the connecting blocks and docking grooves can effectively shorten the overall disassembly time and improve the convenience of disassembly, thereby effectively reducing the cleaning difficulty of this device.

[0007] Preferably, a guide post is fixedly connected to the inner wall of the docking groove, and a through groove adapted to the guide post is opened inside the connecting block.

[0008] Preferably, a support block is fixedly connected to the outer wall of the fixing block, and the side of the support block is connected to a connecting rod via a spring, and the other end of the connecting rod is fixedly connected to a connecting plate.

[0009] Preferably, there are two sets of connecting blocks and fixing blocks, and the two sets of connecting blocks and fixing blocks are symmetrically distributed about the central axis of the protective net.

[0011] Preferably, the outer wall of the protective net is fitted with a rubber ring, and the outer diameter of the rubber ring is compatible with the inner diameter of the connecting ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device is equipped with connecting blocks and docking slots.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 An airflow guiding structure for an aging furnace includes a guide cylinder 1. A connecting ring 2 is fixedly connected to the end of the guide cylinder 1. Holes are equidistantly opened inside the connecting ring 2. The holes are fixed to the furnace wall by bolts 14. The specific connection method between the bolts 14 and the furnace wall is existing technology and will not be described in detail here. A protective net 3 is distributed on the inner side of the connecting ring 2, and a connecting block 4 is fixedly connected to the outer side of the protective net 3. The connecting block 4 is inserted into a docking groove 5, and the docking groove 5 is opened inside a fixing block 6. The side of the fixing block 6 is fixedly connected to the connecting ring 2. A crossbar 7 is inserted inside the fixing block 6, and a connecting plate 8 is fixedly connected to the end of the crossbar 7. A fixing groove adapted to the crossbar 7 is opened inside the connecting block 4. During use, the fast disassembly and assembly of the protective net 3 can be met by the cooperation of the fixing groove and the crossbar 7.

[0018] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the inner wall of the docking groove 5 is fixedly connected with a guide post 12, and the inside of the connecting block 4 is provided with a through groove that is compatible with the guide post 12. During use, the tightness of the connection between the connecting block 4 and the docking groove can be improved by the cooperation between the guide post 12 and the through groove.

[0019] Furthermore, refer to Figure 3 It can be seen that the outer wall of the fixing block 6 is fixedly connected to the support block 9, and the side of the support block 9 is connected to the connecting rod 11 through the spring 10. The other end of the connecting rod 11 is fixedly connected to the connecting plate 8. In use, the elasticity of the spring 10 itself can effectively ensure the reliability of the crossbar 7 when it is inserted into the fixing groove on the side of the connecting block 4.

[0020] Furthermore, refer to Figure 1 and Figure 2 It can be seen that there are two sets of connecting blocks 4 and fixing blocks 6, and the two sets of connecting blocks 4 and fixing blocks 6 are symmetrically distributed about the central axis of the protective net 3. During use, the two sets of connecting blocks 4 and fixing blocks 6 can further ensure the stability of the protective net 3 when it is installed inside the connecting ring 2.

[0021] Furthermore, refer to Figure 1 and Figure 2It can be seen that the two sets of connecting blocks 4 are fixedly connected to the side of each other with a pull rod 13, and the outer wall of the pull rod 13 is covered with a rubber sleeve. During use, the pull rod 13 can provide a gripping point for the staff to improve the convenience of use. With the rubber sleeve, it can effectively prevent the staff from slipping during the gripping process.

[0022] Furthermore, refer to Figure 1 It can be seen that the outer wall of the protective net 3 is fitted with a rubber ring, and the outer diameter of the rubber ring is compatible with the inner diameter of the connecting ring 2. The rubber ring is not shown in the figure. The rubber ring glued to the outer wall of the protective net 3 can reduce the gap between the connecting ring 2 and the outer wall of the protective net 3 during installation, so as to ensure the stability of the connection process.

[0023] Working principle: When using this utility model, the operator can first insert the guide tube 1 into the reserved hole opened in the furnace chamber of the aging furnace, and then connect and fix the connecting ring 2 and the inner wall of the furnace chamber with multiple sets of bolts 14. With the setting of the guide tube 1, the airflow generated by the blower during operation can be guided in a concentrated manner. With the protective net 3 distributed on the inner side of the connecting ring 2, the probability of foreign objects entering the interior of the guide tube 1 can be reduced. When the protective net 3 needs to be disassembled for cleaning, the staff can manually pull the two sets of connecting plates 8 away from each other, so that the crossbar 7 connected to the connecting plate 8 is simultaneously subjected to force, thereby pulling the crossbar 7 out of the fixing groove opened inside the connecting block 4. Then, the protective net 3, which is released from the limit, can slide down under gravity. The staff only needs to pull the pulling rod 13 to quickly disassemble the protective net 3 from the inside of the connecting ring 2 for maintenance. After maintenance, the staff can pull the pulling rod 13 again and insert the connecting block 4 into the docking groove 5. Since the crossbar 7 is set as an inclined structure, the crossbar 7 automatically snaps into the side of the connecting block 4 to achieve quick installation of the protective net 3. The above is the entire working principle of this utility model.

[0024] In this utility model, the installation, connection or setting methods of all the above components are common mechanical methods, and the specific structure, model and coefficient index of all its components are its own technology. As long as it can achieve its beneficial effect, it can be implemented, so it will not be described in detail.
