Description

Technical Field

[0001] This utility model relates to the field of sorting, and in particular to a coal gangue sorting device. Background Technology

[0002] In the current gangue sorting process, a common challenge is that the gangue is often covered with coal, which makes machine identification and sorting quite difficult. Traditional sorting methods mainly rely on machines to identify the visual or physical characteristics of gangue and coal. However, when the surface of the gangue is covered with coal, this identification method is often interfered with, resulting in poor sorting results.

[0003] Therefore, it is necessary to propose a coal gangue sorting device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a coal gangue sorting device to solve the problem mentioned above that when coal ore adheres to the surface of the gangue, this identification method is often interfered with, resulting in poor sorting effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a coal gangue sorting device, including a frame, a feeding end installed on the frame, a crushing roller for crushing coal and gangue installed on the inner wall of the feeding end, and a magnetic separation conveyor belt for conveying the crushed coal and gangue installed on the inner wall of the frame.

[0006] A screen is slidably installed on the inner wall of the frame. A dredging component for clearing the screen is installed on the inner wall of the frame. The dredging component includes a sliding groove, which is opened on the inner wall of the frame. Limiting rods are fixedly installed at equal intervals on the inner wall of the sliding groove. The screen slides through the outer wall of the limiting rod and is slidably connected to the inner wall of the sliding groove. Springs are fixedly installed at equal intervals on the inner wall of the sliding groove, and one end of the spring is fixed to the screen. Inclined grooves are opened at equal intervals on the inner wall of the frame. A rotating rod is rotatably installed on the inner wall of the inclined groove. A hammer is fixedly installed on the outer wall of the rotating rod, and torsion springs are sleeved on both ends of the rotating rod. One end of the torsion spring is fixed to the inner wall of the inclined groove, and the other end of the torsion spring is fixed to the hammer.

[0007] Preferably, a first collection box is slidably disposed on the inner wall of the frame for collecting gangue, and a second collection box is slidably disposed on one side of the frame for collecting coal.

[0008] Preferably, a drive component for driving the crushing rollers is installed on one side of the feed end. The drive component includes pulleys, which are fixed on the side of the two crushing rollers away from the feed end. The two pulleys are driven by a belt, and one of the pulleys is fixed to the output end of the motor.

[0009] Preferably, the bottom of the first and second collection boxes are equipped with self-locking casters.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model uses a crushing roller at the feeding end to uniformly crush gangue and coal ore attached to gangue to the same particle size. At the same time, the application of a magnetic separation conveyor belt enables rapid sorting of the crushed material, effectively distinguishing gangue rich in magnetic materials from coal ore with low magnetic material content, thus improving sorting efficiency.

[0012] 2. This utility model brings a significant improvement in screening efficiency through automatic screen clearing. When the screen is carrying materials, the automatic compression spring slides along the limit rod, driving the rotating rod to rotate and the hammer to strike the screen, effectively preventing the screen holes from clogging. This automated process not only reduces the need for manual intervention, but also ensures a more uniform distribution of materials through the vibrating screen, promoting the rapid passage of fine particles, thereby significantly improving the screening accuracy and overall efficiency.

[0019] This utility model provides, for example Figure 1 - Figure 5The coal gangue sorting device shown includes a frame 1 with a feed end 2 installed on it. A crushing roller 3 for crushing coal and gangue is installed on the inner wall of the feed end 2. A magnetic conveyor belt 4 for transporting the crushed coal and gangue is installed on the inner wall of the frame 1. When gangue enters the feed end 2, the crushing roller 3 starts, uniformly crushing it to the same particle size. Simultaneously, a magnetic conveyor belt 4 is also equipped inside the frame 1. This conveyor belt not only transports materials but also has a magnetic separation function. With its unique magnetic properties, the magnetic conveyor belt 4 can effectively distinguish and adsorb magnetic substances in the gangue. Since the content of magnetic substances in coal is very low, while gangue is rich in such substances, when the crushed gangue falls onto the magnetic conveyor belt 4, it is quickly adsorbed onto it, while the coal continues to move forward with the conveyor belt until it reaches the designated discharge position.

[0020] A drive component for driving the crushing roller 3 is installed on one side of the feed end 2. The drive component includes pulleys, which are fixed on the side of the two crushing rollers 3 away from the feed end 2. The two pulleys are driven by a belt. One of the pulleys is fixed to the output end of the motor. The motor drives one of the pulleys to rotate, and the rotation of one pulley drives the other pulley through the belt. When the two pulleys rotate, they drive the crushing roller 3 to rotate. This is existing technology and will not be described in detail.

[0021] Considering the problem that crushed gangue can easily cause the screen 5 to become clogged, a screen 5 is slidably installed on the inner wall of the frame 1. A dredging component for clearing the screen 5 is installed on the inner wall of the frame 1. Specifically, the dredging component includes a sliding groove 6, which is opened on the inner wall of the frame 1. Limiting rods 7 are fixedly installed at equal intervals on the inner wall of the sliding groove 6. The screen 5 slides through the outer wall of the limiting rods 7 and is slidably connected to the inner wall of the sliding groove 6. Springs 8 are fixedly installed at equal intervals on the inner wall of the sliding groove 6, and one end of the springs 8 is fixed to the screen 5. Inclined grooves 9 are opened at equal intervals on the inner wall of the frame 1. A rotating rod 10 is rotatably installed on the inner wall of the inclined groove 9. A hammer 11 is fixedly installed on the outer wall of the rotating rod 10, and torsion springs 12 are sleeved on both ends of the rotating rod 10. One end of the torsion spring 12 is fixed to the inner wall of the inclined groove 9, and the other end of the torsion spring 12 is fixed to the hammer 11.

[0022] When the crushed gangue and coal fall into the screen 5, the screen 5 will compress the spring 8 due to the weight of the load and slide along the limit rod 7. As the screen 5 slides down, it will press the rotating rod 10, causing the rotating rod 10 to rotate. At the same time, the torsion spring 12 is gradually compressed. As the rotating rod 10 rotates, the hammer 11 fixed on it will strike the screen 5, producing a vibration effect. This vibration can effectively clear any gangue or coal particles that may be blocked in the screen holes, ensuring the continuous efficiency of the screening process. As the material on the screen 5 gradually falls off and its weight is reduced, the spring 8 will immediately return to its original shape, pushing the screen 5 to slowly rise along the limit rod 7. At this time, the screen 5 will disengage from the rotating rod 10, and the torsion spring 12 will also release its energy, pushing the hammer 11 back to its original position, preparing for the next clearing action.

[0023] Furthermore, a first collection box 13 is slidably disposed on the inner wall of the frame 1 for collecting gangue, and a second collection box 14 is slidably disposed on one side of the frame 1 for collecting coal. The bottom of the first collection box 13 and the second collection box 14 are equipped with self-locking casters to facilitate the sliding replacement of the first collection box 13 and the second collection box 14, increasing the flexibility of the first collection box 13 and the second collection box 14. After the screen 5 separates the gangue and the coal, the two types of materials will fall onto the magnetic separation conveyor belt 4 below. At this time, the magnetic separation conveyor belt 4, with its strong magnetic force, will tightly attract the gangue rich in magnetic materials and steadily convey it into the first collection box 13. The coal, due to its low magnetic content, will not be attracted, but will continue to move with the conveyor belt and eventually fall into the second collection box 14.
