Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, specifically to a small-particle coal gangue airflow sorting device. Background Technology

[0002] Coal gangue is a solid waste generated during coal mining and washing. It is a dark gray rock with a low carbon content and harder than coal, which is associated with coal seams during coal formation. It includes gangue from tunnel excavation, gangue extracted from the roof, floor, and interlayers during mining, and gangue removed during coal washing. Coal gangue can be used to produce various building materials, such as sintered bricks, lightweight aggregates, and coal gangue wool.

[0003] In response, Chinese utility model patent CN220991174U discloses a waste lithium battery debris airflow sorting device, belonging to the field of debris airflow sorting technology.

[0029] Furthermore, the diameter and thickness of the positioning block 303 are equal to the diameter and depth of the positioning groove 103, respectively.

[0030] Please see Figure 4 and Figure 6 The inner walls of the sorting box 1 are symmetrically fixed with support blocks 6.

[0031] Furthermore, the length and width of the screening box 7 are equal to the length and width of the inner wall of the sorting box 1, respectively.

[0032] Please see Figure 1 A controller 15 is installed on the outer wall of the sorting box 1.

[0033] Example 2:

[0034] Please see Figure 2 , Figure 5 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment;

[0035] Specifically, a motor 10 is installed on the outer wall of the sorting box 1. The drive end of the motor 10 extends into the sorting box 1 and is fixed to one end of a rotating rod 11. The other end of the rotating rod 11 is rotatably connected to the inner wall of the sorting box 1. The rotating rod 11 is located below the screening box 7. A rotating disk 12 is fixed to the rotating rod 11. The rotating disk 12 contacts the screen 702. A protrusion 1201 is fixed to the outer ring of the rotating disk 12. The top surface of the screening box 7 contacts the bottom surface of the moving washer 13. The moving washer 13 is engaged in the telescopic groove 305 provided on the bottom surface of the box cover 3. The inner wall of the telescopic groove 305 is symmetrically provided with limiting grooves 306. The outer ring of the washer 13 is symmetrically fixed to the limiting block 1301, which is respectively engaged in the limiting groove 306. The top surface of the movable washer 13 is symmetrically fixed to one end of the spring 14, and the other end of the spring 14 is respectively fixed to the bottom surface of the telescopic groove 305. The equipment can drive the protrusion 1201 to rotate through the rotating disk 12. The protrusion 1201 will lift the screening box 7 during the movement. When the protrusion 1201 no longer contacts the screening box 7, the spring 14 will squeeze the movable washer 13 and press the screening box 7 down, which will vibrate the material in the screening box 7 and better sort it.

It is first sorted by the screen 702, and the screened material falls into the sorting box 1. The blower 8 blows the coal gangue material through the air inlet 104, separating materials of different weights and discharging them through the discharge port 105 and the discharge pipe 9 from the sorting box 1. The equipment can sort materials by adjusting the power of the blower 8. The equipment can also control the motor 10 to rotate the rotating rod 11 via the controller 15, causing the rotating disk 12 to drive the protrusion 120. When the device rotates, the protrusion 1201 will lift the screening box 7 during the movement. As the screening box 7 moves, it will lift the moving washer 13 and compress the spring 14. When the protrusion 1201 no longer contacts the screening box 7, the spring 14 will squeeze the moving washer 13 and press the screening box 7 down, which will vibrate the material inside the screening box 7 and better sort it. The device can remove the box cover 3 by removing the fixing bolt 4, so that the screening box 7 can be taken out from the sorting box 1 for easy material handling and cleaning of the screen 702, avoiding blockage that may affect the sorting work.
