Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 5 As shown, the utility model provides a coal gasification slag flotation device, comprising a body 1, a flotation device 2 fixedly provided on the top of the body 1, which continuously floats the coal gasification slag, a bracket 3 fixedly provided on the outer top of the flotation device 2, a collection tank frame 4 fixedly provided on the left side of the body 1, the collection tank frame 4 is positioned by the bracket 3, and a flotation component 5 is further provided between the two brackets 3;

[0027] The flotation assembly 5 includes a rotating shaft 51 rotatably arranged between the two brackets 3, a fixed block 52 is fixedly arranged on the outside of the rotating shaft 51, a lifting shaft 53 is inserted into the interior of the fixed block 52, a slot 58 is provided on the surface of the fixed block 52, an insert block 54 fixed to the lifting shaft 53 is inserted into the interior of the slot 58, and a support frame 6 is fixed to the other end of the lifting shaft 53. The lifting shaft 53 is lifted and lowered inside the fixed block 52 by stretching and is positioned by the insert block 54.

[0028] Specifically, a vertical groove is opened inside the lifting shaft 53, and a U-shaped spring piece 55 is fixedly set inside the vertical groove of the lifting shaft 53. The U-shaped spring piece 55 structure can keep the lifting shaft 53 in an open state. A connecting block 56 is fixed inside the U-shaped spring piece 55, and a positioning bolt 57 that passes through the fixed block 52 is spirally set inside the connecting block 56. The positioning bolt 57 is inserted into the interior of the connecting block 56 to avoid excessive external force, which causes the U-shaped spring piece 55 to deform and the lifting shaft 53 to slide.

[0029] Furthermore, a screening frame 7 is rotatably provided inside the support frame 6, and a partition 8 is fixedly provided in the middle position of the screening frame 7. The screening frame 7 is provided as a semi-arc plate with leakage holes on the surface, which can better separate bubbles or scum. Both ends of the screening frame 7 are fixedly provided with a horizontal plate 9, and a spring 10 is fixedly provided on the outside of the horizontal plate 9, and the other end of the spring 10 is fixed to the support frame 6. The spring 10 is pulled by the horizontal plate 9 to control the screening frame 7 to rotate and then reset.

[0030] Among them, the flotation device 2 is the existing technology and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0031] Working principle and process:

[0032] The staff puts the coal gasification slag into the interior of the body 1 and continuously floats the slag through the flotation device 2. The flotation assembly 5 between the brackets 3 performs the flotation operation, and the slag can be floated to the interior of the collection tank frame 4 for sorting. Before the sorting operation, the lifting shaft 53 inside the fixed block 52 can be pulled and stretched according to the amount of flotation and the height of water replenishment. The lifting shaft 53 is pressed to deform, and the U-shaped spring piece 55 is pushed to deform, and the plug 54 outside the lifting shaft 53 is controlled to disengage from the slot 58, and the lifting shaft 53 is lifted upward. , or press the lifting shaft 53 down into the interior of the fixed block 52, thereby adjusting the support frame 6 at the other end of the lifting shaft 53 to move up and down. After adjusting to a better flotation height, the flotation operation begins. The driving motor structure can control the rotation of the rotating shaft 51, thereby driving the screen frame 7 and the partition 8 to rotate. After the bubbles pass through the leakage holes of the screen frame 7, the bubbles can be separated to avoid affecting the sorting operation. During the sorting process, the rotation of the screen frame 7 can be reset by pulling the cross plate 9 by the spring 10, and the flotation operation is continuously performed.

[0033] After adjusting the height of the lifting shaft 53, insert the insert block 54 into the corresponding slot 58, loosen the lifting shaft 53, push it to expand through the U-shaped spring piece 55, and then insert the positioning bolt 57 into the interior of the fixed block 52 and tighten it between the connecting blocks 56 between the U-shaped spring pieces 55 to maintain the expansion degree of the U-shaped spring pieces 55 to prevent external forces from affecting the up and down movement of the lifting shaft 53 inside the fixed block 52.
