Description

Technical Field

[0001] The utility model relates to the technical field of belt cleaning, and more particularly to a combined belt cleaner. Background Art

[0002] Belt conveyors are a type of mechanical equipment widely used in industrial production, logistics, and other fields. They transport materials from one location to another via a continuously running belt. The belt and rollers are key components of a belt conveyor. The rollers, located beneath the belt, primarily support the belt, reducing friction and ensuring smooth operation.

[0003] During transportation, the belt will carry a variety of bulk, granular, and powdered materials with complex compositions. Some of these materials will adhere to the belt and, when they come into contact with the lower rollers during the return journey, they will rub against the lower rollers and remain on the rollers. This will in turn cause the belt to deviate and wear the lower rollers, affecting the belt's transportation efficiency and service life. Frequent manual cleaning of the belt and lower rollers is required, which carries high safety risks and is labor-intensive, resulting in frequent downtime and low work efficiency. In recent years, various belt scraper cleaners have also appeared. Although they can scrape off some materials, they cause extremely serious damage to the belt, significantly shortening the belt's service life, and making it impossible to classify and collect magnetic materials for recycling.

[0004] Therefore, it is necessary to provide a combined belt cleaner to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a combined belt cleaner to solve the above technical problems.

[0028] 1. The magnetic materials attached to the surface of the return belt in this solution will be adsorbed by the magnetic adsorption mechanism inside the stainless steel roller sleeve, and the stainless steel roller sleeve will drive the magnetic materials to a position away from the magnetic adsorption mechanism through rotational inertia and then drop them into the collection box, thereby collecting the magnetic materials attached to the belt, which can not only be recycled and reused to reduce waste, but also improve the cleaning effect of the belt surface.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See also Figure 1-6 A combined belt cleaner is used to clean the outer surface of the belt 2 on the belt conveyor 1. The belt conveyor 1 is provided with a lower roller 20, which contacts the outer surface of the belt 2. It includes: a collection box 3, which is arranged at the bottom of the belt 2, and a support frame 4 is provided on the outer wall of the collection box 3; a stainless steel roller sleeve 5, which is rotatably arranged in the collection box 3, and a driving mechanism 6 for driving the stainless steel roller sleeve 5 to rotate is provided on the support frame 4; a magnetic adsorption mechanism 7, which is arranged in the stainless steel roller sleeve 5, and is used to adsorb magnetic materials on the outer surface of the belt 2; a flushing mechanism 8, which is arranged in the collection box 3, and is used to flush the outer surface of the belt 2, and a partition 21 is also provided in the collection box 3.

[0042] When the belt conveyor 1 is in operation, the belt 2 thereon moves to transport the material. When the belt is transported on the return journey, before passing the lower roller 20, it will first pass through the area of ​​the belt cleaner, that is, pass above the collection box 3. When the return belt contacts the stainless steel roller 5, the magnetic material attached to the surface of the return belt will be adsorbed by the magnetic adsorption mechanism 7 inside the stainless steel roller 5, so that the magnetic material adheres downward to the surface of the stainless steel roller 5. At the same time, the driving mechanism 6 will drive the stainless steel roller 5 to rotate continuously. When the stainless steel roller 5 drives the magnetic material to a position away from the magnetic adsorption mechanism 7 through rotational inertia and then throws it off, the magnetic material will fall into the collection box 3 and be collected on one side of the partition 21. In this way, the magnetic material attached to the belt can be collected, which can not only be recycled and reused to reduce waste, but also improve the cleaning effect of the belt surface, reduce the wear on the belt surface and the lower roller 20, and have a good use effect.

[0043] After passing through the stainless steel roller sleeve 5, the belt moves to the flushing mechanism 8, which flushes the outer surface of the belt 2 again at a certain angle, further cleaning the surface of the belt 2. This significantly reduces the amount of material adhering to the belt 2, thereby reducing the bidirectional wear caused by the contact between the belt 2 and the lower roller 20. It can also reduce the deviation wear of the belt 2, greatly improving the belt's transportation performance and service life. The number of cleaning times required by staff will be greatly reduced, significantly reducing labor intensity and safety risks, and improving work efficiency. It also prevents the serious damage to the belt 2 caused by current belt scraper cleaners, making it highly practical.

[0044] In this embodiment, preferably, please refer to Figure 2-4 The drive mechanism 6 includes two hollow shafts 61, which are rotatably mounted on either side of the material collection box 3. The stainless steel roller 5 is connected between the two hollow shafts 61. A ring gear 62 is mounted on the outer wall of the hollow shaft 61. A drive member 63 is mounted on the support frame 4. The output end of the drive member 63 is equipped with a gear 64 that meshes with the ring gear 62. The drive member 63 in this application can be a servo motor. When the drive member 63 is activated, it drives the gear 64 to rotate. The gear 64 in turn drives the ring gear 62 and the hollow shaft 61 to rotate. The hollow shaft 61 then drives the stainless steel roller 5 to rotate. At this time, the magnetic adsorption mechanism 7 does not rotate within the stainless steel roller 5.

[0045] In this embodiment, preferably, please refer to Figure 2-5The magnetic adsorption mechanism 7 includes a rotating shaft 71 rotatably mounted on the support frame 4. An adjustment handle 72 is provided at one end of the rotating shaft 71, and the other end passes through the hollow sleeve 61 and extends into the stainless steel roller sleeve 5. An outer sleeve 73 is mounted on the rotating shaft 71. A bracket 74 is provided on the outer wall of the outer sleeve 73, and a magnet 75 is provided on the outer end of the bracket 74. When the belt 2 moves over the stainless steel roller sleeve 5, the magnetic material on the belt 2 is attracted downward by the magnet 75. At this time, the magnetic material is adsorbed on the outer surface of the stainless steel roller sleeve 5. When the stainless steel roller sleeve 5 rotates, the magnetic material is driven to rotate. When the magnetic material rotates to a position away from the magnet 75, the magnetic material loses sufficient adsorption force and is thrown into the collection box 3 by the rotational inertia.

[0046] By rotating the adjustment handle 72 to drive the rotating shaft 71 to rotate, the rotating shaft 71 can drive the outer sleeve 73 and the bracket 74, and the bracket 74 can drive the magnet 75 to rotate. At this time, the azimuth angle of the magnet 75 in the stainless steel roller sleeve 5 can be adjusted, that is, the angle and distance between the magnet 75 and the belt 2 can be adjusted according to actual needs, which has strong flexibility and good use effect.

[0047] In this embodiment, preferably, please refer to Figure 2-4 A limit plate 9 is also provided on the outside of the rotating shaft 71, and a plurality of limit holes 10 are evenly distributed on the limit plate 9. A limit member 11 is provided on the support frame 4 for limiting the rotation of the limit plate 9. After adjusting the azimuth angle of the rotating shaft 71 and the magnet 75 by rotating the adjustment handle 72, the limit plate 9 can be restricted by the limit member 11. At this time, the limit plate 9 and the rotating shaft 71 are restricted, which can ensure the stability of the rotating shaft 71 and the magnet 75 and prevent the rotating shaft 71 and the magnet 75 from deflecting during use.

[0048] In this embodiment, preferably, please refer to Figure 2-4 The limiting component 11 includes: a support plate 111, which is arranged on the support frame 4. A limiting rod 112 that is adapted to the limiting hole 10 is movably passed through the support plate 111; a pulling plate 113, which is arranged at the end of the limiting rod 112. An elastic member 114 is provided between the pulling plate 113 and the support plate 111. The elastic member 114 in the present application can be a spring. Before rotating the adjustment handle 72 and the rotating shaft 71, the pulling plate 113 is first pulled to drive the limiting rod 112 to move. At this time, the limiting rod 112 moves downward and stretches the elastic member 114, so that the limiting rod 112 is separated from the limiting hole 10. Then, the adjustment handle 72 and the rotating shaft 71 can be rotated. After the adjustment is completed, the pulling plate 113 is released. The rebound force of the elastic member 114 can drive the limiting rod 112 to move upward, and the limiting rod 112 is inserted into the limiting hole 10 of the limiting plate 9, thereby limiting the limiting plate 9 and the rotating shaft 71.

[0049] In this embodiment, preferably, please refer to Figure 2 and Figure 5 The flushing mechanism 8 includes a water pipe 81 disposed within the material collecting box 3 and having a plurality of water outlet holes 82 formed therein; and a guide plate 83 obliquely disposed on the outer wall of the water pipe 81. The water pipe 81 is connected to a water pump, a water tank, and other equipment. External water is pumped into the water pipe 81 and then flushed out from the plurality of water outlet holes 82. The guide plate 83 acts to spread the water ejected from the water outlet holes 82, forming a uniform water curtain. This water curtain forms a certain angle to flush the surface of the belt 2, thereby further cleaning the materials adhering to the surface of the belt 2.

[0050] In this embodiment, preferably, please refer to Figure 2 and Figure 5-6 The collection box 3 is also provided with an exhaust pipe 12, which is provided with a plurality of inclined air outlet nozzles 13. The exhaust pipe 12 is connected to an external blower or other equipment. The gas entering the exhaust pipe 12 is ejected through the air outlet nozzles 13, thereby blowing the surface of the belt 2. This not only blows away the part of the material that was not flushed away by the flushing mechanism 8, further cleaning the belt 2 and greatly improving the cleaning effect of the belt 2; it also blows away the residual water on the belt 2, reducing the water on the belt 2 and reducing the impact on the subsequent transportation of the belt 2.

[0051] In this embodiment, preferably, please refer to FIG. Figure 2 and Figure 5-6 The air outlet nozzle 13 is provided with a fixed plate 14, which is provided with a plurality of air outlets 15. A rotating rod 16 is rotatably provided on the fixed plate 14, and a baffle 17 is provided on the baffle 17. The baffle 17 is provided with a plurality of air shields 18 that are compatible with the air outlets 15. The rotating rod 16 can rotate to drive the baffle 17 to rotate, and the rotation of the baffle 17 drives the air shields 18 to rotate, thereby adjusting the overlapping area of ​​the air shields 18 and the air outlet 15. In other words, the air outlet area of ​​the air outlet 15 can be adjusted, and the air pressure ejected from the air outlet nozzle 13 can be adjusted according to actual usage needs, and the application range is wide.

[0052] The outer wall of the air outlet 13 is threadedly connected with a clamping bolt 19. After the baffle 17 and the air shield 18 are adjusted, the clamping bolt 19 can be rotated so that the clamping bolt 19 presses the baffle 17, thereby limiting the movement of the baffle 17 and ensuring its stability during use.
