Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and more specifically, to a magnetic particle dust collector with continuous unloading. Background Technology

[0002] Currently, in the fields of material handling and demagnetization / dust removal, the closest existing technology is an intelligent demagnetizing dust-free feeding device. This device, through the cooperation of components such as a bag filter, conveying mechanism, and demagnetizing filter box, achieves dust-free conveying and removal of magnetic impurities from powdery, granular, and lumpy materials. This technology can adapt to the processing of materials of different forms and can improve the cleanliness and purity of the materials during the feeding process.

[0003] Existing dust collectors are complex in structure, have numerous components, consume high energy during operation, and are inconvenient to maintain and clean. Friction, gaps, or wear can easily occur in the fit of mechanical parts, potentially leading to accumulated measurement errors over long-term use. The demagnetization process relies on a combination of electromagnetic drive belts and rollers, resulting in a relatively long path and limited effectiveness in capturing tiny magnetic particles. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a magnetic particle dust collector with continuous unloading.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses a continuous unloading magnetic particle dust collector, including a cylinder, an inlet flange, and an outlet flange. A lower flange cover and an upper flange cover are respectively installed at the upper and lower ends of the cylinder. A short ventilation pipe connects the cylinder to both the inlet flange and the outlet flange. It also includes a drive mechanism and a turntable. The turntable is located inside the cylinder, and the drive mechanism drives the turntable to rotate. Several tube shells are installed on the turntable, and magnetic rods are placed inside the tube shells. The tube shells are fixedly installed on the turntable and have an open upper end. The upper end of the magnetic rods is flush with the upper plane of the turntable. A discharge pipe passes through the lower flange cover and is located below the movement path of the tube shells. It also includes a lifting mechanism, which is positioned corresponding to the location of the discharge pipe and can lift the magnetic rods in the tube shells that reach the discharge pipe.

[0007] Furthermore, the end of the feed pipe located inside the cylinder is connected to a windproof pipe, which has two openings for the pipe shell to enter and exit.

[0008] Furthermore, a windbreak curtain is installed at the notch on the side of the windproof duct near the air inlet flange.

[0009] Furthermore, the drive mechanism includes a stepper motor, which is connected to a drive pulley. A rotating shaft is connected to the upper end of the turntable. The rotating shaft passes through the upper flange cover and is connected to a driven pulley. A synchronous belt connects the drive pulley and the driven pulley.

[0010] Furthermore, a motor frame is installed on the upper part of the upper flange cover, and a stepper motor is installed on the upper part of the motor frame.

[0011] Furthermore, the tube shell is open at the top and sealed at the bottom, and includes a buffer mechanism located inside the tube shell and below the magnetic rod.

[0012] Furthermore, the buffer mechanism is a spring, which is fixed at the bottom of the tube shell.

[0013] Furthermore, a double-flanged turbine butterfly valve is connected to the lower flange of the feed pipe, and a sealing gasket is provided between the feed pipe and the double-flanged turbine butterfly valve.

[0014] Furthermore, the lifting mechanism includes a cylinder, a connecting piece is mounted on the piston rod of the cylinder, and a vacuum suction cup or magnetic suction head is mounted on the lower end of the connecting piece.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-6 As shown, a continuous discharge magnetic particle dust collector includes a cylinder 1, an inlet flange 2, and an outlet flange 5. A lower flange cover 7 and an upper flange cover 8 are respectively installed at the upper and lower ends of the cylinder 1. A flange gasket 3 is provided between the lower flange cover 7 and the cylinder 1. The lower flange cover 7 and the cylinder 1 are fixed together using a fastening nut 18 and a fastening bolt 19. The upper flange cover 8 and the cylinder 1 are fixed together using a fastening bolt 20.

[0025] A short ventilation pipe 4 is connected between the cylinder body 1 and the air inlet flange 2 and the air outlet flange 5. The included angle between the axes of the air inlet flange 2 and the air outlet flange 5 is 180 degrees. It also includes a drive mechanism and a turntable 11. The turntable 11 is located in the upper part of the cylinder body 1 near the upper flange cover 8. The drive mechanism can drive the turntable 11 to rotate. Several tube shells 15 are installed on the turntable 11. The tube shells 15 are evenly distributed in a circumferential shape on the turntable 11. Magnetic rods 16 are placed inside the tube shells 15. The tube shells 15 are fixedly installed on the turntable 11 and are open at the upper end. The upper end face of the magnetic rod 16 is flush with the upper plane of the turntable 11. A feeding pipe 6 is passed through the lower flange cover 7. The feeding pipe 6 is located below the moving path of the tube shell 15. It also includes a lifting mechanism. The lifting mechanism is set at the position of the feeding pipe 6. The lifting mechanism can lift the magnetic rod 16 in the tube shell 15 that reaches the feeding pipe 6. The upper flange cover 8 has a through hole corresponding to the position of the magnetic rod 16 at this time. The lifting mechanism lifts the upper end of the magnetic rod 16 by attracting it through the through hole.

[0026] The drive mechanism can drive the turntable 11 to rotate, thereby moving the magnetic rods 16 inside the cylinder 1. This allows each magnetic rod 16 to have the opportunity to encounter the high-density magnetic dust at the gas inlet, effectively avoiding the problem of uneven capture of magnetic dust by the outer shells of the fixedly installed magnetic rods 16. This improves the capture efficiency of fine magnetic particles in the airflow, thereby reducing the amount of magnetic rods 16 used, reducing the space occupied by the filter, and lowering production operation and equipment investment costs.

[0027] Simultaneously, the turntable 11 moves the magnetic rod 16 to a designated position above the feed pipe 6. The lifting mechanism then lifts the magnetic rod 16 at this position, causing it to rise within the tube shell 15. This causes the magnetic particles adsorbed on the surface of the tube shell 15 to detach and fall into the feed pipe 6 for collection. This allows for the detachment and collection of magnetic particles without stopping the machine, avoiding the intermittent cleaning required by traditional devices and ensuring continuous system operation.

[0028] Furthermore, one end of the feeding pipe 6 located inside the cylinder 1 is connected to a windproof pipe 44, which has two notches for the casing 15 to enter and exit. After the casing 15 enters the windproof pipe 44, the turntable 11 stops rotating and lifts the magnetic rod 16 for unloading. The unloading of magnetic particles is completed within the windproof pipe 44, minimizing the risk of magnetic dust particles detaching due to airflow disturbance and ensuring collection efficiency. The windproof pipe 44 is positioned between the inlet flange 2 and the outlet flange 5, such that one of the two notches on the windproof pipe 44 is close to and faces the inlet flange 2, and the other is close to and faces the outlet flange 5. A windbreak curtain 39 is installed at the notch on the side of the windproof pipe 44 near the air inlet flange 2. The windbreak curtain 39 is made of a flexible film. The windbreak curtain 39 blocks the air entering from the air inlet flange 2, preventing the airflow from entering the windproof pipe 44 through the notch, thereby preventing the airflow from blowing away the magnetic particles, further enhancing the windproof pipe 44's resistance to airflow disturbance, and realizing the efficient collection of magnetic particles during magnetic rod unloading.

[0029] The feed pipe 6 and the windproof pipe 44 are designed as an integrated unit to effectively avoid the impact of airflow disturbance during material feeding.

[0030] Furthermore, the drive mechanism includes a stepper motor 27, which drives a drive pulley 29. A mounting sleeve 43 is provided on the turntable 11. A rotating shaft 42 is connected to the mounting sleeve 43 via a key 10. The rotating shaft 42 extends out of the upper flange cover 8 and is connected to a driven pulley 28. A synchronous belt 30 connects the drive pulley 29 and the driven pulley 28. A bushing 41 is mounted at the middle of the upper part of the upper flange cover 8 via fastening screw 22. The rotating shaft 42 passes through the bushing 41, and the rotating shaft 42 is rotatably connected to the bushing 41. A sealing ring 9 is installed between the bushing 41 and the upper flange cover 8 to form an effective seal. The stepper motor 27 drives the rotating shaft 42 to rotate through the cooperation of the drive pulley 29, the synchronous belt 30, and the driven pulley 28, thereby driving the turntable 11 to rotate. A magnetohydrodynamic seal is used between the rotating shaft 42 and the bushing 41. A retaining ring 13 is installed at the lower part of the rotating sleeve via fastening screw 14.

[0031] The turntable 11 and the upper flange cover 8 employ a single-tooth or multi-tooth comb-type sealing structure design. Specifically, in this embodiment, the turntable 11 includes a first convex ring 45 located at the top, with a sealing groove on the upper part of the first convex ring 45. A felt strip 12 is installed in the sealing groove. The upper flange cover 8 includes a second convex ring 46 located at the bottom, with a portion of the second convex ring 46 located inside the first convex ring 45 and abutting against the felt strip 12. The felt strip 12 achieves a seal between the turntable 11 and the upper flange cover 8 during rotation, thereby preventing airflow from escaping through the through hole at the upper flange cover 8.

[0032] Furthermore, a motor frame 31 is mounted on the upper part of the upper flange cover 8 by hexagonal screws 32, and the stepper motor 27 is fixedly mounted on the upper part of the motor frame 31 by the cooperation of fastening screws 33 and fastening nuts 34.

[0033] Furthermore, the tube shell 15 is open at the top and sealed at the bottom. The tube shell 15 includes a buffer mechanism located inside the tube shell 15 and below the magnetic rod 16. When the magnetic rod 16 is raised and then slowly lowered, the buffer mechanism effectively reduces the impact, preventing the magnetic rod 16 from colliding with the tube shell 15 and thus reducing its service life. Specifically, the buffer mechanism is a spring 17, which is fixed at the bottom inside the tube shell 15.

[0034] Furthermore, a double-flanged turbine butterfly valve 35 is connected to the lower flange of the feed pipe 6, and a sealing gasket 37 is provided between the feed pipe 6 and the double-flanged turbine butterfly valve 35. A transparent pipe 38 is connected to the lower flange of the double-flanged turbine butterfly valve 35, and the transparent pipe 38 includes a feed outlet flange 36, which connects the transparent pipe 38 to the double-flanged turbine butterfly valve 35. The transparent pipe 38 allows operators to observe the accumulation of magnetic particles in real time, thus enabling timely discharge.

[0035] Furthermore, the lifting mechanism includes a cylinder 40. A fixing frame 21 is mounted on the upper flange cover 8 via fastening screws 23. The cylinder 40 is mounted on the fixing frame 21. A connecting piece 24 is mounted on the piston rod of the cylinder 40 via fastening nuts 25. A vacuum suction cup or magnetic suction head is mounted on the lower end of the connecting piece 24 via fastening nuts 26. The cylinder 40 controls the piston rod to retract, causing the vacuum suction cup or magnetic suction head to descend and pass through the through hole into the cylinder 1, adsorbing the upper end face of the magnetic rod 16. The cylinder 40 then controls the piston rod to extend, causing the vacuum suction cup or magnetic suction head to rise via the connecting piece 24, thereby causing the magnetic rod 16 to rise within the tube shell 15.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
