[0027] A type of slag recycling and crushing equipment, such as Figure 1 and Figure 2 As shown, it includes:

[0028] The main body 10 has a cavity, and two crushing rollers 11 are installed inside the cavity. A drive unit for driving the crushing rollers 11 is installed outside the main body 10. Gears are fixedly installed at the ends of the crushing rollers 11, and the gears of the two crushing rollers 11 mesh with each other. The drive unit can be a geared motor. The output shaft of the geared motor is fixedly connected to the end of one of the crushing rollers 11. The geared motor needs to be connected to a control switch. The slag is fed through the feed hopper at the top of the main body 10, and the two crushing rollers 11 rotating in opposite directions crush the slag to achieve the production of slag powder.

[0029] A screening structure, set inside the cavity of the main body 10, is used to sort the material crushed by the crushing roller 11. The screening structure includes a screen plate 12 and elastic telescopic rods 13. The screen plate 12 is elastically connected to the main body 10. A vibration motor is fixedly installed at the bottom of the screen plate 12. Elastic telescopic rods 13 are set at the four corners of the bottom of the screen plate 12. The output shaft of the elastic telescopic rods 13 is fixedly connected to the screen plate 12. The elastic telescopic rods 13 are fixedly connected to the inner wall of the main body 10. Multiple sets of screening structures can be set inside the cavity of the main body 10. Taking two sets as an example, the screen plate 12 is arranged inclined towards the window. The crushed slag is sorted by two screen plates 12 with different mesh sizes. The powder falls to the bottom of the main body 10 and is discharged from the discharge pipe at the bottom of the main body 10, while larger particles roll down along the top surface of the screen plate 12. Multi-stage screening is achieved while crushing, which improves production efficiency. In addition, the vibration motor can make the screen plate 12 vibrate to a certain extent, which promotes sorting. The elastic telescopic rods 13 can realize the up and down movement of the screen plate 12.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the slag discharge structure is set on one side of the main body 10 to guide the slag discharged from the screen plate 12. The slag discharge structure includes a side cover 20, a first guide trough 21 and a second guide trough 22. The side cover 20 is fixedly connected to the main body 10. The first guide trough 21 is movably set below the side cover 20 and can be adjusted at an angle. The second guide trough 22 is slidably connected to the first guide trough 21. The second guide trough 22 is fixed in position by a second locking structure. The first guide trough 21 is fixed in position by a first locking structure. A window for slag discharge is opened on the side wall of the main body 10. The side cover 20 forms a rectangular cover and faces the window. The first guide trough 21 and the second guide trough 22 are both square troughs. The second guide trough 22 is slidably set at the bottom of the first guide trough 21.

[0031] In this scheme, by rotating the first guide trough 21, the second guide trough 22 is pulled to slide along the first guide trough 21, thereby adjusting the pitch angle of the first guide trough 21. With the second guide trough 22 extending to one side of the first guide trough 21, larger particles can be guided, and the landing point of the particles on the ground can be adjusted within a certain range, resulting in better controllability of the particle stacking location.

[0032] like Figure 3 and Figure 4 As shown, the first locking structure includes a connecting plate 23, thrust holes 24, and a first locking bolt 25.

Several thrust holes 24 arranged in a circular array are opened on the side wall of the connecting plate 23. The first locking bolt 25 passes through the thrust holes 24 and is threadedly connected to the side cover 20. In order to control the pitch angle of the first guide groove 21, the first guide groove 21 is rotated. A rotating shaft is fixedly installed on one side of the connecting plate 23 and is rotatably connected to the side cover 20. By passing the first locking bolt 25 through the thrust holes 24 at different positions and fastening it to the threaded hole on one side of the side cover 20, the pitch angle of the first guide groove 21 is fixed. The operation is simple and easy to adjust.

[0033] like Figure 3 As shown, the second locking structure includes positioning holes 30 and a second locking bolt 31. The sidewall of the second guide channel 22 has several positioning holes 30 linearly formed. The second locking bolt 31 passes through the positioning holes 30 and is threadedly connected to the first guide channel 21. In order to control the position of the second guide channel 22, by pulling the second guide channel 22 to slide along the bottom of the first guide channel 21, the second locking bolt 31 passes through the positioning holes 30 at different positions and is fastened to the threaded holes on the sidewall of the first guide channel 21, thereby fixing the position of the second guide channel 22. The position of the second guide channel 22 can be easily adjusted and locked to change the landing point of the particles.

[0034] The working principle of this utility model is as follows: The drive unit can be a geared motor. The output shaft of the geared motor is fixedly connected to the end of one of the crushing rollers 11. The geared motor needs to be connected to a control switch. Material is fed through the feed hopper at the top of the main body 10. The two counter-rotating crushing rollers 11 crush the slag, achieving the production of slag powder. The crushed slag is sorted by two sieve plates 12 with different mesh sizes. The powder falls to the bottom of the main body 10 and is discharged from the discharge pipe at the bottom of the main body 10, while larger particles roll down along the top surface of the sieve plate 12. Multi-stage screening is achieved simultaneously with crushing. By rotating the first guide chute 21, the second guide chute 22 is pulled to slide along the first guide chute 21, thereby… The pitch angle of the first guide trough 21 can be adjusted, and the second guide trough 22 extends to one side of the first guide trough 21. A rotating shaft is fixedly installed on one side of the connecting plate 23, and the rotating shaft is rotatably connected to the side cover 20. By passing the first locking bolt 25 through the thrust hole 24 at different positions and fastening it to the threaded hole on one side of the side cover 20, the pitch angle of the first guide trough 21 is fixed. The second guide trough 22 is pulled to slide along the bottom of the first guide trough 21, and the second locking bolt 31 is passed through the positioning hole 30 at different positions and fastened to the threaded hole on the side wall of the first guide trough 21, the position of the second guide trough 22 is fixed, and the landing point of the rolling particles on the screen plate 12 is controlled.
