Description

Technical Field

[0001] This utility model relates to the field of bell-type annealing technology, and in particular to a bell-type inner bell-type furnace cleaning device. Background Technology

[0002] When bell-type furnaces perform multiple heat treatments on copper and copper alloy strips, a large amount of oxides adheres to the inner wall surface of the inner shroud. These oxides cause problems such as thickening of the inner wall, poor heat transfer, and reduced furnace thermal efficiency. Furthermore, the adhered oxides are easily detached, which can have a significant impact on strips requiring high surface quality. Currently, most methods for cleaning oxides from the inner wall of bell-type furnaces rely on manual mechanical cleaning. This method is labor-intensive, time-consuming, and may pose safety hazards such as inhaling dust during the cleaning process.

[0003] Currently, some enterprises use mechanical cleaning methods. However, most mechanical cleaning equipment can only clean a specific part of the furnace inner wall or use a single cleaning method, making it difficult to achieve comprehensive and efficient cleaning of the entire furnace inner wall. If residues on the inner wall are not properly removed over a long period, the dirt will corrode the furnace inner wall, especially when the dirt contains acidic or alkaline substances. Long-term corrosion will significantly shorten the equipment's lifespan, affect the process, and may also cause gas leaks, leading to safety accidents. To solve the above technical problems, it is necessary to provide a bell-type inner furnace cleaning device. Utility Model Content

[0004] To address the aforementioned issues, the spray pipes can rotate 360° inside the bell furnace, ensuring that the cleaning solution is effectively and thoroughly sprayed onto every part of the furnace's inner wall. This effectively cleans the inner wall, improves product quality, and the independent liquid supply design makes the cleaning solution supply system less prone to damage, reducing maintenance intensity.

[0005] The cleaning device for the inner hood furnace provided by this utility model includes a water tank, a support platform and a spray pipe. The water tank is installed on one side of the support platform. The lower end of the spray pipe passes through the support platform and is connected to a rotating main shaft. The lower end of the rotating main shaft is connected to a rotary joint. One end of the rotary joint is fixed and connected to the water tank.

[0006] Preferably, the spray control mechanism includes a motor base adjustment plate welded to the lower surface of the support platform, a motor fixedly mounted on the motor base adjustment plate, a small pulley coaxially connected to the output end of the motor, a large pulley fixedly connected to the lower end of the rotating main shaft, and the small pulley and the large pulley being connected to the same synchronous belt drive.

[0007] Preferably, the rotating spindle further includes a deep groove ball bearing and a tapered roller bearing. The lower end of the rotating spindle is provided with a deep groove ball bearing, and the upper end of the rotating spindle is provided with a tapered roller bearing. Both the deep groove ball bearing and the tapered roller bearing are fixed to the load-bearing platform by retaining rings.

[0008] Preferably, it also includes a sewage pump, one end of which is connected to one end of the water tank via a pipe, and the other end of the water tank is connected to the rotary joint via a pipe.

[0009] Preferably, the rotating spindle further includes a rubber sealing ring, an internal hexagonal head screw, and a nut. The rotating spindle is fixed to the rubber sealing ring by the internal hexagonal head screw and the nut, and the rotating spindle is connected to the spray pipe upward.

[0010] Preferably, the spray pipe further includes stainless steel fan-shaped nozzles, and the spray pipe has a centrally symmetrical branch pipe on each side, each branch pipe is supported by two connecting pipes, and each branch pipe has six stainless steel fan-shaped nozzles.

[0011] Preferably, four guide columns are installed at the lower end of the support platform, and the two ends of the guide columns are fixed to the ground by pre-embedded screws.

[0012] Compared with related technologies, this utility model has the following beneficial effects: This solution utilizes an independent water tank and wastewater pump for liquid supply, coupled with a spray control mechanism, allowing the spray pipes to smoothly spray cleaning fluid onto the inner wall of the furnace through stainless steel fan-shaped nozzles. This effectively cleans the inner wall, improving product quality and equipment lifespan. Furthermore, the spray control mechanism's design enables 360° cleaning of the bell-shaped furnace's inner wall, increasing the cleaning area and improving cleaning efficiency.

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] This utility model embodiment provides a hood-type inner hood furnace cleaning device, such as... Figure 1 and 2 As shown, the system includes a water tank 1, a support platform 2, and a spray pipe 22. The water tank 1 is installed on one side of the support platform 2. The lower end of the spray pipe 22 passes through the support platform 2 and is connected to a rotating main shaft 11. The lower end of the rotating main shaft 11 is connected to a rotary joint 10. One end of the rotary joint 10 is fixed and connected to the water tank 1. A spray control mechanism is also installed on the support platform 2 to rotate the spray pipe 22 360 degrees and spray the cleaning liquid onto the inner wall of the furnace from all directions.

[0018] In the above structure, the spray control mechanism is used to spray cleaning liquid all-round on the inner wall of the furnace. Specifically, the spray control mechanism includes a motor base adjustment plate 4 welded to the lower surface of the support platform 2. A motor 6 is fixedly installed on the motor base adjustment plate 4. A small pulley 8 is coaxially connected to the output end of the motor 6. A large pulley 7 is fixedly connected to the lower end of the rotating main shaft 11. The small pulley 8 and the large pulley 7 are connected to the same synchronous belt 9. The motor 6 drives the small pulley 8 to rotate. Since the small pulley 8 and the large pulley 7 are connected by the synchronous belt 9, the rotation of the small pulley 8 will drive the rotation of the large pulley 7. Therefore, the rotation of the large pulley 7 will drive the rotation of the rotating main shaft 11, thereby driving the spray pipe 22 to rotate. The spray pipe 22 also includes stainless steel fan-shaped nozzles 19. The spray pipe 22 has a centrally symmetrical branch pipe on each side. Each branch pipe is supported by two connecting pipes. Each branch pipe has six stainless steel fan-shaped nozzles 19. The spray is sprayed onto the inner wall of the furnace through the stainless steel fan-shaped nozzles 19 of the spray pipe 22.

[0019] The rotating spindle 11 also includes a deep groove ball bearing 12 and a tapered roller bearing 14. The lower end of the rotating spindle 11 is provided with a deep groove ball bearing 12, and the upper end of the rotating spindle 11 is provided with a tapered roller bearing 14. Both the deep groove ball bearing 12 and the tapered roller bearing 14 are fixed to the load-bearing platform 2 by retaining rings, so that the rotating spindle 11 is supported and limited when rotating, making the operation more stable.

[0020] It also includes a sewage pump 18, one end of which is connected to one end of the water tank 1 through a pipe, and the other end of the water tank 1 is connected to the rotary joint 10 through a pipe. Under the action of the sewage pump 18, the cleaning liquid enters the rotary joint 10 through the water tank 1. When it is necessary to clean the inner wall of the furnace, the spray pipe 22 is rotated by the spray control mechanism and sprayed evenly through the stainless steel fan-shaped nozzle 19.

[0021] The rotating spindle 11 also includes a rubber sealing ring 15, an internal hexagonal head screw and a nut. The rotating spindle 11 and the rubber sealing ring 15 are fixed together by the internal hexagonal head screw and nut. The rotating spindle 11 is connected to the spray pipe 22 upwards. The design of the rubber sealing ring 15 prevents oil and liquid leakage.

[0022] Four guide columns 20 are installed at the lower end of the load-bearing platform 2. The two ends of the guide columns 20 are fixed to the ground by pre-embedded screws to enhance stability.

[0023] Specifically, during use, in the initial state, there is cleaning liquid in the water tank 1. Under the action of the sewage pump 18, the cleaning liquid enters the rotary joint 10 through the pipe. When it is necessary to clean the inner wall of the furnace, the motor 6 of the spray control mechanism drives the small pulley 8 to rotate. Since the small pulley 8 and the large pulley 7 are connected by the synchronous belt 9, the rotation of the small pulley 8 will drive the large pulley 7 to rotate, thereby driving the rotating main shaft 11 and the spray pipe 22 to rotate. Finally, the stainless steel fan-shaped nozzles 19 of the spray pipe 22 spray onto the inner wall of the furnace. Multiple stainless steel fan-shaped nozzles 19 achieve multi-point spraying.

[0024] In summary, compared with related technologies, this solution, by setting up independent liquid supply for the water tank 1 and the sewage pump 18, and cooperating with the spray control mechanism, allows the spray pipe 22 to smoothly spray cleaning liquid onto the inner wall of the furnace through the stainless steel fan-shaped nozzles 19, effectively cleaning the inner wall, improving product quality and equipment lifespan. Simultaneously, the design of the spray control mechanism allows for 360° cleaning of the bell-shaped furnace inner wall, increasing the cleaning area and improving cleaning efficiency. The sewage pump 18 facilitates the entry of cleaning liquid into the high-pressure rotary joint 10, connecting to the rotating main shaft 11, allowing the cleaning liquid to be pumped into the rotating main shaft 11 and then into the spray pipe 22, where it is sprayed onto the inner wall of the furnace by the stainless steel fan-shaped nozzles 19.

[0025] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
