A screen 4 is provided inside the placement box 2, and a feed port 5 is provided on the top of the screen 4. L-shaped blocks 6 are fixedly installed on both sides of the feed port 5. The bottom of the L-shaped block 6 is fixedly installed on the top of the placement box 2. A concentrating cyclone body 7 is provided on the right side of the funnel 1, and a screening component 8 for screening the coarse coal slime is provided inside the placement box 2. The surface of the concentrating cyclone body 7 is fixedly installed with a The ring 9 has a connecting block 10 fixedly installed at the bottom. First, the coarse coal slime to be recovered is placed in the feed port 5. At this time, the coarse coal slime inside the feed port 5 will enter the screen 4. Then, the coarse coal slime can be screened by the screening component 8. At this time, larger pieces of coarse coal slime will continue to remain in the screen 4, and smaller pieces of coarse coal slime will enter the funnel 1. Finally, the coarse coal slime will enter the inside of the concentrating cyclone body 7. At this time, the clean coal is discharged from the top of the concentrating cyclone body 7 through the rotation inside the concentrating cyclone body 7. The discharged coal is recovered, and the mud and sand are discharged from the bottom of the concentrating cyclone body 7.
[0031] Reference Figure 1-5 The screening assembly 8 includes two groups of protrusions 81. A rotating rod 82 is installed inside the placement box 2. The rotating rod 82 and the protrusion 81 are fixedly installed. One side of the protrusion 81 contacts one side of the screen 4. The front end of the rotating rod 82 passes through the front side of the placement box 2 and is fixedly installed with a motor 83. A support seat 84 is fixedly installed at the bottom of the motor 83. The back side of the support seat 84 is fixedly installed with the front side of the placement box 2. Through the cooperation of the protrusion 81, the rotating rod 82, the motor 83 and the support seat 84, the rotating rod 82 can be driven to rotate when the motor 83 is started. The rotation of the rotating rod 82 drives the protrusion 81 to rotate. The rotation of the protrusion 81 will contact the screen 4. At this time, the screen 4 will shake inside the placement box 2, so that the coarse particles in the screen 4 can be removed. The coal slime is screened, and the front and rear sides of the left side of the screen 4 are fixedly installed with a spring 85, and the left end of the spring 85 is fixedly installed to the left side of the inner wall of the placement box 2. Through the setting of the spring 85, the screen 4 can be squeezed to the leftmost side of the placement box 2 under the action of the protrusion 81. At this time, the protrusion 81 will continue to rotate to reset it. At this time, the spring 85 will release the elastic force, thereby screening the coarse coal slime in the screen 4. The front and rear sides of the right side of the screen 4 are fixedly installed with a tension spring 86, and the right end of the tension spring 86 is fixedly installed to the right side of the inner wall of the placement box 2. Through the setting of the tension spring 86, the screen 4 can be moved to the right. At this time, under the action of the tension spring 86, the screen 4 will move faster, thereby screening the coarse coal slime in the screen 4.
[0032] Reference Figure 1-5 The left side of the concentrating cyclone body 7 is connected with a first conveying bucket 11, and a second conveying bucket 12 is fixedly installed at the bottom of the funnel 1. The first conveying bucket 11 is located at the bottom of the second conveying bucket 12. Through the cooperation of the first conveying bucket 11 and the second conveying bucket 12, the finer coal slime entering the funnel 1 can enter the second conveying bucket 12. At this time, the second conveying bucket 12 will let the finer coal slime enter the first conveying bucket 11. Finally, the finer coal slime in the first conveying bucket 11 will enter the concentrating cyclone body 7 for recovery. The top of the concentrating cyclone body 7 is connected with a first pipe 13. The first pipe The surface of the concentrating cyclone 7 is connected to a first valve 14. By the mutual cooperation of the first conduit 13 and the first valve 14, the first valve 14 can be opened. At this time, finer clean coal will enter the interior of the concentrating cyclone body 7. At this time, the concentrating cyclone body 7 rotates inside and discharges the finer clean coal through the first conduit 13. The bottom of the concentrating cyclone body 7 is connected to a second conduit 15. The surface of the second conduit 15 is connected to a second valve 16. By the mutual cooperation of the second conduit 15 and the second valve 16, when the second valve 16 is opened, the sediment inside the concentrating cyclone body 7 can be discharged through the second conduit 15.
[0033] Working principle: First, put the coarse coal slime to be recycled into the feed port 5. At this time, the coarse coal slime inside the feed port 5 will enter the screen 4. Then the motor 83 can be started. The output end of the motor 83 will drive the rotating rod 82 to rotate. The rotation of the rotating rod 82 drives the protrusion 81 to rotate. The rotation of the protrusion 81 will contact the screen 4. At this time, the screen 4 will shake inside the placement box 2. At this time, when the screen 4 is squeezed to the far left, the protrusion 81 will continue to rotate to reset it. At this time, the spring 85 will release the elastic force, and under the action of the tension spring 86 The screen 4 will move faster, so that the coarse coal slime in the screen 4 will be screened. The screened coal slime will enter the funnel 1, and the funnel 1 can convey the coal slime to the first conveying bucket 11. At this time, the first conveying bucket 11 will convey the coal slime to the second conveying bucket 12. Finally, the coal slime will enter the concentrating cyclone body 7. At this time, the concentrating cyclone body 7 will rotate inside and discharge the finer clean coal through the first pipe 13, and the mud and sand will be discharged through the second pipe 15, thereby achieving the advantage of recovering the coarse coal slime.
