DETAILED DESCRIPTION

[0022] Please refer to Figures 1-6A magnetic levitation fan energy-saving air conveying system for a tin smelting fuming furnace includes a housing 1. From left to right, a first partition 2, a second partition 3, and a third partition 4 are fixedly connected to the inner cavity of the housing 1. A hydraulic rod 5 is bolted to the right side of the bottom of the inner cavity of the housing 1. By setting the hydraulic rod 5, the magnetic levitation fan 7 can be raised during equipment maintenance, facilitating inspection and maintenance of its bottom and surrounding area. The output end of the hydraulic rod 5 is bolted to a frame 6. The magnetic levitation fan 7 is placed at the bottom of the inner cavity of the frame 6. Electric push rods 8 are bolted to the front and rear sides of the frame 6, with the output end of the electric push rod 8 penetrating through... A pressure sensor 9 is bolted to the inside of the frame 6. The pressure sensor 9 is mainly used to monitor the pressure of the clamping plate 10 on the magnetic levitation fan 7 and prevent the clamping plate 10 from being too tight or too loose. The clamping plate 10 is bolted to the opposite side of the pressure sensor 9. A cleaning mechanism 11 is bolted to the bottom right side of the first partition 2. The cleaning mechanism 11 includes a servo motor 12. The output end of the servo motor 12 passes through the first partition 2 and is bolted to a lead screw 13. A threaded tube 14 is fixedly connected to the left side of the first partition 2. A filter cylinder 15 is threaded on the surface of the threaded tube 14.

[0023] Please see Figure 1 and Figure 3 A movable plate 16 is threaded on the right side of the lead screw 13. By setting the movable plate 16, the lead screw 13 rotates under the drive of the servo motor 12. Since the movable plate 16 is threaded on the lead screw 13, the rotation of the lead screw 13 will convert the circular motion into the linear motion of the movable plate 16. This allows the movable plate 16 to move along the axial direction of the lead screw 13. A cleaning ring 17 is riveted to the top of the movable plate 16. A cleaning brush 18 is provided on the inner wall of the cleaning ring 17. A guide rod 19 is movably connected through the left side of the movable plate 16. The left end of the guide rod 19 is riveted to the inner wall of the housing 1, and the right end of the guide rod 19 is riveted to the first partition 2.

[0024] Please see Figure 1 An air inlet pipe is connected to the top left side of the housing 1. The function of the air inlet pipe is to introduce outside air into the housing 1 of the air delivery system. An exhaust pipe is connected to the top right side of the housing 1.

[0025] Please see Figure 1 The top of the housing 1 is movably connected to the cover plate 20 via a hinge. The front and rear sides of the top right side of the cover plate 20 are riveted with buckles, and the front and rear sides of the top right side of the housing 1 are riveted with locking blocks that match the buckles. By setting the buckles and locking blocks, the cover plate 20 can be firmly fixed to the housing 1, enhancing the sealing performance of the cover plate 20, preventing air leakage, and ensuring the normal operation and efficiency of the pneumatic conveying system.

[0026] Please see Figure 1 and Figure 2Sealing strips 21 adapted to the magnetic levitation fan 7 are riveted to the right side of the second partition 3 and the left side of the third partition 4. By setting the sealing strips 21, a seal is formed between the magnetic levitation fan 7 and the second partition 3 and the third partition 4 to prevent air from leaking from these gaps. A sealing plate 22 is bolted to the left side of the front side of the housing 1.

[0027] Please see Figure 1 Rectangular holes 23 are provided on the left side of the second partition 3 and the left side of the third partition 4. A receiving box 24 is placed on the left side of the bottom of the inner cavity of the housing 1. The receiving box 24 is used to collect the dust and impurities cleaned from the filter cartridge 15.

[0028] In use, connect the exhaust pipe to the ventilation duct of the fumigation furnace, connect the device to an external power supply and controller, and control the operation of the magnetic levitation fan 7 through the external controller. At this time, a negative pressure is generated inside the housing 1, and outside air enters the interior of the housing 1 through the air inlet pipe. The filter cartridge 15 filters the dust and impurities contained in the air. The filtered air enters the interior of the fumigation furnace through the rectangular hole 23 and the exhaust pipe. When it is necessary to clean the surface of the filter cartridge 15, the external controller controls the servo motor 12 to operate. The output end of the servo motor 12 drives the lead screw 13 to rotate. The lead screw 13 is threadedly connected to the movable plate 16, which in turn causes the movable plate 16 to rotate. The movable plate 16 moves the cleaning ring 17 and cleaning brush 18. The cleaning brush 18 brushes away the dust adhering to the surface of the filter cartridge 15. The dust falls into the inside of the receiving box 24. When the magnetic levitation fan 7 needs to be inspected, the cover plate 20 is opened, and then the external controller controls the hydraulic rod 5 to work. The output end of the hydraulic rod 5 drives the frame 6 and the magnetic levitation fan 7 to move upward. The magnetic levitation fan 7 moves to the top of the housing 1, and then the external controller controls the electric push rod 8 to retract. The electric push rod 8 drives the clamping plate 10 to move, thereby releasing the limit on the magnetic levitation fan 7. The user can then disassemble the magnetic levitation fan 7.

[0029] In summary, this energy-saving air delivery system for a magnetic levitation fan used in a tin smelting fuming furnace, through the cooperation of a cleaning mechanism 11, a servo motor 12, a lead screw 13, a hydraulic rod 5, a frame 6, a magnetic levitation fan 7, an electric push rod 8, a pressure sensor 9, and a clamping plate 10, solves the problems of existing air delivery devices that cannot regularly clean the dust adhering to the surface of the filter cartridge during use, and that make it inconvenient for users to quickly disassemble and repair the magnetic levitation fan.
