For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Example 1, as Figures 1-7 shown, a high-efficiency screening device for multi-stage activated carbon processing and its screening method. A connecting frame 2 is fixedly connected to the top of the base 1. The top of the inner wall of the base 1 is fixedly connected with a first motor 3. A rotating rod 4 is rotatably inserted into the top of the base 1. The rotating rod 4 and the first motor 3 are rotatably connected through a bearing.

When using the screening device, the raw materials are placed into the screening device through the feed port, and the sieve mesh 5 arranged on the surface of the rotating rod 4 is driven by the motor to rotate, so that the raw materials can be screened in multiple stages.

[0028] Refer to Figures 2 to 4, the connecting device 7 includes a moving block 704. The surface of the rotating rod 4 is evenly provided with limiting grooves 701. The sieve 5 is slidably connected to the inner wall of the limiting groove 701. The bottom of the inner wall of the limiting groove 701 is fixedly connected with a first damping rod 702. The top of the first damping rod 702 and the bottom of the sieve 5 are fixedly connected. A first spring 703 is sleeved on the surface of the first damping rod 702. The bottom of the first spring 703 and the bottom of the inner wall of the limiting groove 701 are fixedly connected. One end of the first spring 703 close to the first damping rod 702 and the bottom of the sieve 5 are fixedly connected. The moving block 704 and the sieve 5 are fixedly connected to the top of the connecting frame 2 close to each other. A connecting block 705 is fixedly connected to the inner wall of the connecting frame 2. First inclined surfaces 706 are provided on both sides of the connecting block 705. When using the connecting device 7, when the sieve 5 is driven to rotate due to the rotation of the rotating rod 4, the moving block 704 presses on the first inclined surface 706 provided on the side of the connecting block 705, thereby causing the first spring 703 to be compressed. When the moving block 704 moves away from the connecting block 705, the first spring 703 returns to its original state and drives the sieve 5 to slide upward on the inner wall of the limiting groove 701, so that the sieve 5 hits the top of the limiting groove 701. This will, to a certain extent, knock out the raw materials stuck in the mesh holes of the sieve 5. The connecting sleeve 6 is slidably sleeved on the surface of the connecting frame 2. A connecting groove 707 is provided at the bottom of the connecting sleeve 6. A connecting ring 708 is provided on the inner wall of the connecting groove 707. The bottom of the connecting ring 708 and the top of the base 1 are fixedly connected. A second damping rod 709 is fixedly connected to one side of the base 1.

A second spring 710 is sleeved on the surface of the second damping rod 709. One end of the second spring 710 and one side of the base 1 are fixedly connected. One end of the second spring 710 close to the second damping rod 709 and one side of the fixed frame 711 are fixedly connected. After sleeving the connecting sleeve 6 on the surface of the connecting frame 2, the second spring 710 pulls the fixed frame 711 in the direction close to the base 1 and sleeves the top of the fixed frame 711 on the top of one side of the connecting sleeve 6. In this way, the connecting sleeve 6 is arranged to wrap the sieve 5. Reverse operation can expose the sieve 5. This can well clean the raw materials stuck in the mesh holes of the sieve 5. A second inclined surface 712 is provided at the top of the fixed frame 711. Grooves 713 are evenly provided on the second inclined surface 712. A round rod 714 is fixedly connected to the inner wall of the groove 713. A cylinder 715 is rotatably sleeved on the surface of the round rod 714. When the connecting sleeve 6 is sleeved on the connecting frame 2, the bottom of the connecting sleeve 6 presses on the second inclined surface 712 provided at the top of the fixed frame 711, thereby driving the cylinder 715 to rotate. This facilitates squeezing the fixed frame 711 to one side, and then the connecting sleeve 6 can be sleeved on the top of the connecting frame 2. The top of one side of the connecting sleeve 6 is evenly fixedly connected with clamping plates 716. The two clamping plates 716 are arranged on both sides of the fixed frame 711.The top of the clamping plate 716 is fixedly connected to a third damping rod 717.

One end of the third spring 718 close to the third damping rod 717 is fixedly connected to the bottom of one side of the L-shaped plate 719. The end of the L-shaped plate 719 away from the third damping rod 717 is arranged on the side of the fixed frame 711 away from the second damping rod 709. After the fixed frame 711 is sleeved on the top of one side of the connecting sleeve 6, the third spring 718 pulls the L-shaped plate 719 in the direction close to the clamping plate 716, and then arranges the end of the L-shaped plate 719 away from the third damping rod 717 on the side of the fixed frame 711 away from the connecting sleeve 6, so that the fixed frame 711 can be well restricted on the surface of one side of the connecting sleeve 6.,

[0029] Refer to Figures 5 to 7, the grinding device 8 includes a support cylinder 806. The support cylinder 806 is arranged on the top of the connecting sleeve 6. The inner wall of the support cylinder 806 is evenly and rotatably penetrated and inserted with connecting rods 808. The surface of the connecting rod 808 is fixedly connected with extrusion rollers 810. When using the grinding device 8, the support cylinder 806 is arranged on the top of the connecting sleeve 6, and the raw materials are placed into the support cylinder 806 through the top of the support cylinder 806, so that the raw materials can pass through the extrusion rollers 810. Control the rotation of the extrusion rollers 810, so that the raw materials can be initially broken, which is convenient for subsequent screening. One end of the connecting rod 808 far away from the support cylinder 806 is fixedly connected with a gear 809. The two gears 809 are meshed with each other. The surface of the support cylinder 806 is fixedly connected with a second motor 807. The second motor 807 and the connecting rod 808 are connected together through bearings. The second motor 807 can drive one connecting rod 808 to rotate. Because the two gears 809 are meshed with each other, the two connecting rods 808 can rotate relatively, and then the two extrusion rollers 810 can rotate relatively, which is convenient for grinding the raw materials. The bottom of the support cylinder 806 is fixedly connected with a sliding cylinder 802. The sliding cylinder 802 is slidably inserted into the inner wall of the top of the connecting sleeve 6. The surface of the sliding cylinder 802 is fixedly connected with a limiting sleeve 801. A rectangular groove 803 is opened in the inner wall of the limiting sleeve 801. A rectangular block 804 is slidably connected to the inner wall of the rectangular groove 803. The rectangular block 804 is fixedly connected to the surface of the top of the connecting sleeve 6. Rubber blocks 805 are evenly fixedly connected to the inner wall of the rectangular groove 803 far away from the rectangular block 804. Slide the sliding cylinder 802 into the inner wall of the top of the connecting sleeve 6, and sleeved the limiting sleeve 801 on the surface of the rectangular block 804. At the same time, the rubber blocks 805 are squeezed to the bottom of the rectangular block 804, so that the support cylinder 806 can be well arranged on the top of the connecting sleeve 6. A conical sleeve 811 is fixedly connected to the inner wall of the top of the support cylinder 806. The opening at the bottom of the conical sleeve 811 is arranged between the two extrusion rollers 810. The conical sleeve 811 is convenient for placing the raw materials between the two extrusion rollers 810.

[0030] Working principle: When using the screening device, place the raw materials into the interior of the screening device through the feeding port. Drive the screen 5 arranged on the surface of the rotating rod 4 to rotate through the motor, so that the raw materials can be screened at multiple levels. When using the connecting device 7, when the screen 5 is driven to rotate due to the rotation of the rotating rod 4, the moving block 704 presses on the first inclined surface 706 opened on the side of the connecting block 705, thereby causing the first spring 703 to be compressed. When the moving block 704 moves away from the connecting block 705, the first spring 703 returns to its original state and drives the screen 5 to slide upward on the inner wall of the limiting groove 701, so that the screen 5 collides with the top of the limiting groove 701. To a certain extent, this can knock out the raw materials stuck in the mesh holes of the screen 5. Additionally, after sleeving the connecting sleeve 6 on the surface of the connecting frame 2, during the process of sleeving the connecting sleeve 6 on the connecting frame 2, the bottom of the connecting sleeve 6 presses on the second inclined surface 712 opened on the top of the fixed frame 711, thereby driving the cylinder 715 to rotate, which facilitates squeezing the fixed frame 711 to one side, so that the connecting sleeve 6 can be sleeved on the top of the connecting frame 2. The second spring 710 pulls the fixed frame 711 in the direction close to the base 1 and sleeves the top of the fixed frame 711 on the top of one side of the connecting sleeve 6. After the fixed frame 711 is sleeved on the top of one side of the connecting sleeve 6, the third spring 718 pulls the L-shaped plate 719 in the direction close to the clamping plate 716, and sets the end of the L-shaped plate 719 away from the third damping rod 717 on the side of the fixed frame 711 away from the connecting sleeve 6. In this way, the fixed frame 711 can be well restricted on the surface of one side of the connecting sleeve 6, so that the connecting sleeve 6 wraps the screen 5. Reversing the operation can expose the screen 5, which can well clean the raw materials stuck in the mesh holes of the screen 5.

[0031] It should be noted that all the damping rods in this case are telescopic dampers, which can absorb energy during the telescopic process.
