[0034] Specifically, the top driving mechanism comprises a cam 16 and a top seat 17, the cam 16 is fixedly sleeved on the transmission shaft 15 and located in the screening box 2, and the top seat 17 is fixedly installed at the bottom of the screening plate 11 and located at the right side of the screen 12.

[0035] Specifically, the conveying mechanism comprises a conveying shaft 13 and helical blades 14, the conveying shaft 13 is rotatably installed at the bottom inner wall and the top inner wall of the conveying box 4, the helical blades 14 are arranged on the conveying shaft 13 and located above the partition plate 10, and a gear driving mechanism is arranged between the conveying shaft 13 and the transmission shaft 15.

[0036] Specifically, the gear driving mechanism comprises two bevel gears 25, the bevel gears 25 are fixedly sleeved on the conveying shaft 13 and the left end of the transmission shaft 15 and located below the partition plate 10, and the two bevel gears 25 are meshed.

[0037] Specifically, the transmission mechanism comprises two transmission wheels 18 and a transmission belt 19, and the transmission wheels 18 are fixedly sleeved on the output shaft of the motor 5 and the rotating shaft 15, the transmission wheels 18 are located in the function box 3, and the same transmission belt 19 is sleeved on the two transmission wheels 18.

[0038] Specifically, the separation mechanism comprises a hydrocyclone 20, an overflow pipe 23, a sand trap 22 and a filter box 24, the hydrocyclone 20 is arranged on the left side of the conveying box 4, the hydrocyclone 20 and the screening box 2 are communicated through the feeding pipe 21, the bottom of the hydrocyclone 20 is provided with the sand trap 22, the top of the hydrocyclone 20 is provided with the overflow pipe 23, and the left side of the hydrocyclone 20 is provided with the filter box 24, and the filter box 24 and the overflow pipe 23 are communicated through a connecting pipe.

[0039] In the application, during operation, first, the slag enters from the top feeding pipe of the slag crushing box 1, the motor 5 drives the crushing roller 6 to rotate, which cooperates with the crushing teeth 7 on the inner wall of the slag crushing box 1 to crush the slag. This crushing method can effectively break the large slag into small particles suitable for subsequent processing, and can improve the separation efficiency. The crushed slag enters the screening box 2 through the discharge port 8, the motor 5 drives the rotating shaft 15 to rotate through the transmission wheel 18 and the transmission belt 19, the cam 16 on the rotating shaft 15 rotates with it, and cooperates with the bottom pedestal 17 of the screening plate 11 to make the screening plate 11 vibrate. This vibrating screening method is simple in structure and efficient. The screen 12 on the screening plate 11 screens the slag and water mixture through the screening port 9. The large particles pass through the screen 12 and the screening port 9 into the conveying box 4, and the small particles and water mixture pass through the feeding pipe 21 into the hydrocyclone 20, which can effectively avoid the influence of large particles on the subsequent separation link. The rotating shaft 15 drives the conveying shaft 13 to rotate through the bevel gear 25, and the spiral blade 14 rotates, which can drive the large particle slag to be conveyed upwards and re-enter the slag crushing box 1 through the feeding port, so as to achieve the purpose of re-crushing the large particle slag and fully crushing the slag, thereby improving the separation efficiency of the slag and water. When the slag and water mixture enters the hydrocyclone 20 through the feeding pipe 21, under the action of pressure, the slag and water mixture enters the hydrocyclone 20 along the tangent direction, and then forms a high-speed rotating flow field in the cylinder. Based on the density difference between the slag particles and water, under the strong action of centrifugal force, the slag particles with larger density are strongly thrown to the wall of the hydrocyclone 20. These slag particles move downward along the wall in a spiral manner and finally smoothly discharge from the sand discharge nozzle 22. The water with smaller density forms an upward inner vortex in the area close to the axis due to the relatively small centrifugal force, and then flows out from the overflow pipe 23, and then enters the filter box 24 to remove impurities, thereby achieving the purpose of water recycling and recycling. This separation process fully utilizes the high-efficiency separation performance of the hydrocyclone 20 and the good purification capacity of the filter box 24, which are both mature technical solutions, can effectively improve the water recovery quality and reduce water resource waste, and at the same time ensure complete slag separation. The whole device is compact in design and closely coordinated in each link, which is conducive to improving the overall efficiency and economy of the blast furnace slag treatment.
