The following embodiments are used to illustrate this utility model.

[0029] A blast furnace slag treatment device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including

[0030] Support 10, processing tank 11 is fixedly installed on support 10, discharge port 12 is provided at the bottom of processing tank 11, inlet 15 is provided at the top of processing tank 11, air pump 13 is provided on support 10, and air pump 14 is provided on the top surface of processing tank 11.

[0031] The processing assembly is movably disposed within the processing tank 11. The processing assembly includes a spiral edge bar 17, a crushing blade 20, a pulverizing blade 21, an electromagnetic rod 22, a coarse screen plate 23, and a fine screen plate 24. The fine screen plate 24 is movably disposed below the coarse screen plate 23. The coarse screen plate 23 and the fine screen plate 24 are movably disposed within the processing tank 11. The spiral edge bar 17, the crushing blade 20, and the pulverizing blade 21 are all fixedly connected to the electromagnetic rod 22. The electromagnetic rod 22 is rotatably disposed between the processing tank 11, the coarse screen plate 23, and the fine screen plate 24.

[0032] Specifically, blast furnace slag enters the processing tank 11 through the feed inlet 15. After being processed by the processing components, the blast furnace slag is discharged through the discharge outlet 12. By setting up the processing components, the coarse screen plate 23 and the fine screen plate 24, together with the air pump 13 to deliver gas and the gravity of the falling blast furnace slag to form elastic vibration, filter the blast furnace slag. Then, the crushing blade 20, the pulverizing blade 21 and the electromagnetic rod 22 are used to crush the slag and remove iron filings. The processing unit is gathered in the processing tank 11, saving space and energy consumption, while improving processing efficiency. The air pump 13 delivers gas to cool the blast furnace slag. The waste heat in the blast furnace slag heats the cold gas. The spiral edge bar 17 guides the heated waste gas upward in a spiral. The exhaust pump 14 extracts the waste gas and returns it to the blast furnace. The waste heat recovery is completed, and the linkage effect with the processing components is formed to improve the blast furnace slag processing efficiency and realize the recovery and reuse of energy consumption, thereby reducing energy costs.

[0033] like Figure 1 , Figure 2 and Figure 5As shown, an air outlet pipe 18 is fixedly installed on the top of the processing tank 11. An air extraction pump 14 communicates with the interior of the processing tank 11 through the air outlet pipe 18. An air inlet pipe 19 is installed on the curved side of the processing tank 11. An air supply pump 13 communicates with the interior of the processing tank 11 through the air inlet pipe 19. Multiple J-shaped ventilation holes 29 are arranged in a ring array on the inner wall of the processing tank 11. The air inlet pipe 19 communicates with the ventilation holes 29 and with the sliding groove 28. The output end of the air outlet pipe 18 is connected to a blast furnace and a cooling device. The input ends of both the air outlet pipe 18 and the air inlet pipe 19 communicate with the interior of the processing tank 11. Figure 2 As shown, a motor 16 is fixedly installed on the top surface of the processing tank 11. The output end of the motor 16 is connected to a shaft. The shaft is rotatably connected to the processing tank 11. A wire 33 is installed inside the shaft. Multiple electromagnetic rods 22 of different specifications are arranged in an array on the curved surface of the shaft. The wire 33 is electrically connected to the electromagnetic rods 22. The wire 33 is connected to an external power supply. The arrangement shape of the electromagnetic rods 22 corresponds to the shape of the processing tank 11.

[0034] Specifically, during use, the power supply connected to the wire 33 is turned on, and the wire 33 supplies power to the electromagnetic rod 22, causing a strong magnetic field to be formed on the surface of the electromagnetic rod 22. The cold air in the cold air device is delivered to the processing tank 11 through the air inlet pipe 19 and the vent 29 by the air pump 13. Then, the rotation of the shaft, the spiral edge 17 and the electromagnetic rod 22 is driven by the motor 16. The rotating spiral edge 17 guides the airflow inside the processing tank 11. The airflow spirals upward through the spiral edge 17. After being heated by the residual heat in the blast furnace slag, the rising airflow is discharged into the blast furnace through the air outlet pipe 18 by the air pump 14. Simultaneously, the rotation of the electromagnetic rod 22 continuously adsorbs the iron filings in the blast furnace slag. After the blast furnace slag treatment is completed, the power supply of the wire 33 is turned off. In the power-off state, the iron filings adsorbed by the electromagnetic rod 22 can fall off and be discharged and collected through the discharge port 12.

[0035] like Figure 2 and Figure 3 As shown, the spiral edge strip 17, the crushing blade 20 and the pulverizing blade 21 are all fixedly connected to the wall surface of the shaft. Multiple crushing blades 20 are arranged in an array above and below, and multiple crushing blades 20 are located above the coarse screen plate 23. The pulverizing blade 21 is located between the coarse screen plate 23 and the fine screen plate 24. The spiral edge strip 17 is set to fit against the inner wall surface of the processing tank 11.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, a rim 26 is fixedly provided on the top surface of the coarse screen plate 23 and the bottom surface of the fine screen plate 24 respectively. A grooved ring 30 is fixedly provided on the bottom surface of the coarse screen plate 23, and a T-shaped ring 31 is fixedly provided on the top surface of the fine screen plate 24. The T-shaped ring 31 moves through the grooved ring 30, and the outer wall of the rim 26 is in contact with the inner wall of the processing tank 11.

[0037] like Figure 4 and Figure 5 As shown, multiple square plates 25 are fixedly arranged on the curved sides of the coarse screen plate 23 and the fine screen plate 24. A sliding groove 28 is provided on the inner wall of the processing tank 11. A support rod 32 is fixedly installed in the sliding groove 28. The square plate 25 moves between the sliding groove 28 and the support rod 32. A round hole is provided inside the square plate 25, and the round hole corresponds to the support rod 32. The support rod 32 passes through the round hole. The square plate 25 slides up and down in the sliding groove 28.

[0038] like Figure 4 and Figure 5 As shown, a spring 27 is fixedly installed inside the chute 28. The spring 27 is sleeved on the support rod 32. The square plate 25 of the coarse screen plate 23 and the square plate 25 of the fine screen plate 24 are both fixedly connected to the spring 27. The chute 28 elastically connects the coarse screen plate 23 and the fine screen plate 24 through the spring 27. The chute 28 consists of an annular groove and four square grooves. The square plate 25 moves up and down in the square grooves. The coarse screen plate 23 and the fine screen plate 24 both move up and down in the annular grooves.

[0039] The specific implementation method is as follows: During use, when blast furnace slag enters the processing tank 11 through the feed inlet 15, the power supply of the motor 16 and wire 33, the air pump 13, and the air extraction pump 14 are started synchronously. The motor 16 drives the shaft to rotate, and the shaft drives the spiral strip 17, the crushing blade 20, the pulverizing blade 21, and the electromagnetic rod 22 to rotate. Simultaneously, the air pump 13 draws cold air from the cold air device through the air inlet pipe 19 and enters the processing tank 11. The crushing blade 20 crushes the blast furnace slag, and the crushed blast furnace slag falls onto the coarse screen plate 23 and the fine screen plate 24 for sequential filtration and screening. The pulverizing blade 21 pulverizes the blast furnace slag that falls onto the secondary screen plate 24. Simultaneously, the cold air carries away the heat carried by the blast furnace slag as it passes through it, at which point the cold air becomes warm air. Warm air is guided by the spiral edge strip 17 and drawn out by the air pump 14 through the air outlet pipe 18. Simultaneously, the blast furnace slag falling on the coarse screen plate 23 and fine screen plate 24 is blown out by the cold air blown out of the air vent 29 and continuously comes into contact with the crushing knife 20 and the pulverizing knife 21 and is crushed. At the same time, it is subjected to the double impact of the gravity of the falling blast furnace slag and the rising cold air blown out of the air inlet pipe 19. The coarse screen plate 23 and fine screen plate 24, in conjunction with the corresponding spring 27, begin to vibrate up and down in the chute 28. At this time, the square plate 25 vibrates up and down in conjunction with the support rod 32 and the square groove, while the edge 26 vibrates up and down along the inner wall of the processing tank 11. The T-shaped ring 31 moves up and down in conjunction with the groove ring 30. The edge 26 prevents the blast furnace slag from entering the chute 28 and clogging the spring 27.
