Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, specifically to an automatic belt cleaning device for an eddy current separator. Background Technology

[0002] Eddy current separators are commonly used to recover copper and aluminum from scrap steel and slag. The main components of an eddy current separator include a magnetic drum, a drive drum, a material conveyor belt, and a frame. The magnetic drum is the core component; a motor drives the drive drum, which in turn drives the material conveyor belt. The high-speed rotation of the magnetic rollers inside the magnetic drum generates an alternating magnetic field, thus separating the copper and aluminum materials. During operation, the material is conveyed to the eddy current separator belt. As the belt rotates, the material is transported to the high-speed magnetic drum. Weakly magnetic materials such as copper and aluminum in the material are lifted by the high-frequency alternating magnetic field, effectively separating them from other materials. Other non-magnetic materials are unaffected by the alternating magnetic field and are conveyed to the tail bin by the belt.

[0003] Since the material entering the equipment is sand and soil, which has a certain degree of stickiness, some residue will adhere to the surface of the belt during the conveyor belt process. As the working time increases, the sand and soil accumulated on the surface of the belt will also increase. Some impurities will stick together with aluminum and other materials, and will be ejected with the aluminum, affecting the cleanliness of the aluminum. However, the existing equipment does not have the function of belt cleaning, and manual cleaning is required after the equipment is used, which is time-consuming and labor-intensive.

[0004] Based on this, the present utility model is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0020] This utility model solution is applicable to belt conveyor equipment for conveying waste materials, see reference. Figure 1 The device mainly consists of two drive rollers 10 and a belt 11. The belt 11 is mounted on the two drive rollers 10. The drive rollers 10 can be automatic force rollers. When they rotate, they drive the belt 11 to move, thereby conveying the material on the belt 11 in a directional manner. This allows it to work in conjunction with external magnetic rollers or other equipment. The drive rollers 10 can also be powered by an external motor or other equipment. This device is existing technology; any commercially available model that meets the requirements can be selected.

[0021] Please see Figure 1 , Figure 2 An automatic belt cleaning device for an eddy current separator includes: a brush mounting frame 1, a cleaning brush 2, an adjusting rod 3, a fixed base 4, a bearing seat 5, a chain 6, a sprocket 7, and an external metal frame 100.

[0022] There are two brush mounting brackets 1, symmetrically arranged, which are the main supporting components of the entire equipment. There are also two fixed bases 4, each hinged to one of the two brush mounting brackets 1. The brush mounting brackets 1 are connected to the external metal frame 100 via the fixed bases 4, ensuring the overall stability of the equipment. The cleaning brushes 2 are rotatably mounted between the two brush mounting brackets 1 at both ends via bearing seats 5. The cleaning brushes 2 contact the surface of the external conveyor belt 11 used for conveying waste materials. The rotation of the cleaning brushes 2 cleans the sand and dirt from the surface of the conveyor belt 11. An adjusting rod 3 is mounted on the external metal frame 100 and rotatably connected to the top of one of the brush mounting brackets 1. The adjusting rod 3 adjusts the pressure of the cleaning brushes 2 on the surface of the conveyor belt 11, thereby adjusting the cleaning effect.

[0023] The adjusting rod 3 includes a connector 31, a lead screw 32, and positioning bolts 33. The connector 31 is rotatably mounted on the top of one of the brush mounting brackets 1 via a pin, and the lead screw 32 is fixedly connected to the side of the connector 31 away from the brush mounting bracket 1. An adjustment slot 101 is provided on the external metal frame 100, and the lead screw 32 passes through the adjustment slot 101. There are two positioning bolts 33, both threaded onto the lead screw 32, and the two positioning bolts 33 are located on opposite sides of the external metal frame 100. In use, pulling the lead screw 32 adjusts its relative position to the external metal frame 100 and fixes it with the two positioning bolts 33. During this process, the brush mounting bracket 1 can be rotated, thereby adjusting the position of the cleaning brush 2 relative to the belt 11. Thus, during use, depending on the degree to which different materials adhere to the belt 11, the clamping force of the cleaning brush 2 on the surface of the belt 11 can be controlled by adjusting the rod 3 to achieve the best cleaning effect on the belt 11.

[0024] One end of the cleaning brush 2 is connected to the shaft of a drive roller 10 via two sprockets 7 and a chain 6, ensuring that the cleaning brush 2 rotates simultaneously with the drive roller 10. Specifically, one sprocket 7 is connected to one end of the cleaning brush 2, the other sprocket 7 is connected to the shaft of the drive roller 10, and the chain 6 meshes with both sprockets 7. In use, when the drive roller 10 rotates and drives the belt 11, the cleaning brush 2 rotates synchronously in opposite directions via the transmission of the sprockets 7 and the chain 6, thus cleaning the surface of the belt 11. Furthermore, a chain cover 9 is bolted to the external metal frame 100. The chain cover 9 is located outside the chain 6 and sprockets 7, protecting the chain drive mechanism.

[0025] Further reference Figure 3 , Figure 4 and Figure 5 The device also includes a tensioner 8, which is mounted on an external metal frame 100. The tensioner 8 can control the tension of the chain 6. The tensioner 8 includes: a fixed base 81, a swing rod 82, a tensioning wheel 83, a positioning bolt 84, a groove 85, a spring 86, a first locking block 87, a first slot 88, a second slot 89, and a second locking block 810.

[0026] A fixed base 81 is fixedly mounted on an external metal frame 100. A swing arm 82 is rotatably mounted on the fixed base 81 via a bearing. A tension wheel 83 is rotatably mounted on the free end of the swing arm 82, corresponding to the position of the chain 6. A positioning bolt 84 is rotatably mounted on the fixed base 81 and extends into the inner cavity of the fixed base 81. A groove 85 is formed at one end of the positioning bolt 84 extending into the inner cavity of the fixed base 81. A spring 86 is installed in the groove 85. One end of a first locking block 87 is connected to the spring 86. A first slot 88 is formed on the inner wall of the fixed base 81. The other end of the first locking block 87 is inserted into the first slot 88, and the first locking block 87 is wedge-shaped. Several second slots 89 are equidistantly formed in the inner cavity of the swing arm 82 along the circumference. A second locking block 810 is fixedly connected to the first locking block 87 and is inserted into one of the second slots 89, wherein the second locking block 810 is rectangular. In actual use, ... Figure 4 To reference the counterclockwise rotation of the positioning bolt 84, the first locking block 87 retracts into the groove 85 using the limiting position of the fixed seat 81. At the same time, the second locking block 810 moves synchronously and leaves the second slot 89. At this time, the swing rod 82 can be rotated to make the tension wheel 83 engage with the chain 6, and the chain 6 is tensioned. Then, the positioning bolt 84 is rotated in the opposite direction, and the elastic force of the spring 86 makes the first locking block 87 re-insert into the first slot 88. During this process, the angle of the swing rod 82 is simultaneously finely adjusted so that the second locking block 810 is inserted into the other second slot 89, thus completing the locking of the swing rod 82.

[0027] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
