The magnetic separation module also includes two magnetic separation frames 22 installed in the screening box 4. The two magnetic separation frames 22 are respectively located below the first filter screen 5 and the second filter screen 6. A plurality of second magnetic rollers 23 are rotatably installed in the two magnetic separation frames 22. A transmission groove 24 is provided on one side of the magnetic separation frame 22. A rotating shaft 26 is fixedly installed on one end of each second magnetic roller 23 close to the transmission groove 24.

A rack 28 meshing with the second gear 27 is slidably installed in the transmission groove 24. A first piston tube 29 is fixedly installed on the outer wall of the magnetic separation frame 22. A first piston rod 30 is movably inserted into the first piston tube 29 at one end near the magnetic separation frame 22, and the first piston rod 30 movably passes through the outer wall of the magnetic separation frame 22 and extends into the transmission groove 24.

A connecting pipe 33 is connected one-to-one between the two second piston tubes 31 and the two first piston tubes 29.

[0024] Two first magnetic rollers 15 are arranged in the feed box 13, wherein the first magnetic roller 15 and the second magnetic roller 23 are both electromagnets, which use their own magnetic force to absorb the metal particles in the mud and the magnets in the sand, which are hereinafter referred to as magnetic materials, to improve the resource utilization rate of the slag. Specifically, the second motor 21 drives one of the first gears 20 to rotate, and the two first gears 20 generate transmission, and the two first gears 20 rotate at the same time, and the rotation directions are opposite, so as to drive the two first magnetic rollers 15 to rotate, such as Figure 4 As shown, the first magnetic roller 15 on the left rotates counterclockwise, while the first magnetic roller 15 on the right rotates clockwise. The magnetic materials adsorbed by the first magnetic roller 15 during its rotation will be scraped off by the scraper 17 and guided into the recovery box 18 through the recovery port 16. It is worth noting that a plurality of flushing pipes can be provided on one side of the feed box 13 to flush the first magnetic roller 15 and wash away the mud and sand adhering to the first magnetic roller 15 to prevent the mud and sand from entering the recovery box 18.

[0025] In addition, a magnetic separation frame 22 is provided below the first filter screen 5 and the second filter screen 6. A plurality of second magnetic rollers 23 are rotatably installed in the magnetic separation frame 22. When the vibration frame 10 vibrates up and down, it will reciprocately press and pull the second piston rod 32. Figure 6 and Figure 7 As shown, when the second piston rod 32 moves upward, the air in the second piston tube 31 enters the first piston tube 29 through the connecting tube 33, and the first piston rod 30 extends out of the first piston tube 29, thereby pushing the rack 28 to slide forward, and through the transmission of the rack 28 and the second gear 27, the plurality of second magnetic rollers 23 are driven to rotate forward, and when the second piston rod 32 moves downward, the second piston tube 31 extracts the air in the first piston tube 29 through the connecting tube 33, and the first piston rod 30 retracts into the first piston tube 29, thereby pushing the rack 28 to slide backward, and through the transmission of the rack 28 and the second gear 27, the plurality of second magnetic rollers 23 are driven to reverse, thereby improving the quality and efficiency of magnetic attraction. Similar to the first magnetic roller 15, some flushing pipes can be set on the magnetic separation frame 22 to flush away the mud and sand on the second magnetic roller 23. The clean water obtained by the subsequent separation of the water level mud used in the above-mentioned flushing pipes can achieve the purpose of recycling.

[0026] refer to Figure 8-Figure 10The device is also provided with a spreading module for spreading the mud, which is used to disperse the mud on the first filter screen 5 and the second filter screen 6, including a mounting plate 34 mounted on the side wall of the screening box 4, a wave chute 35 is arranged on the mounting plate 34, a sliding frame 39 is slidably mounted on the wave chute 35, two push plates 40 are mounted on the sliding frame 39, both ends of the wave chute 35 are connected with a trapezoidal chute 36, a one-way plate 37 is rotatably mounted at the connection between the trapezoidal chute 36 and the wave chute 35, and a torsion spring is provided at the rotation connection, a limit plate 38 is provided on the one-way plate 37 close to the trapezoidal chute 36, and a slide plate 41 is slidably mounted above the first filter screen 5. , and a mounting frame is fixedly installed above the first filter screen 5, a reciprocating screw 44 is rotatably installed on the mounting frame, a threaded hole matched with the reciprocating screw 44 is opened on the slide plate 41, and a driving motor is provided at the end of the reciprocating screw 44, a third piston tube 42 is fixedly installed on the top wall of the sliding frame 39, a third piston rod 43 is movably inserted on the top wall of the third piston tube 42, the top of the third piston rod 43 is fixedly connected to the slide plate 41, a flushing frame 25 is fixedly installed on the bottom wall of the sliding frame 39, a liquid outlet pipe 45 is connected between the flushing frame 25 and the third piston tube 42, the third piston tube 42 is connected to a liquid inlet pipe 46, and the liquid inlet pipe 46 is externally connected to a water tank.

[0027] Because the position of the feed box 13 is fixed, the position of the mud entering the first filter screen 5 is fixed, so that the mud is easy to accumulate at the position of the first filter screen 5 near the feed box 13, which will not only cause the first filter screen 5 to be blocked, but also affect the subsequent magnetic separation and other processes. In order to improve the efficiency and quality of mud screening, spreading modules are respectively set on the first filter screen 5 and the second filter screen 6. The reciprocating screw 44 is driven to rotate by a driving motor, and the slide plate 41 is driven to slide back and forth by the reciprocating screw 44. The slide plate 41 drives the sliding frame 39 below to slide along the mounting plate 34. Since the sliding frame 39 is slidably installed in the wave slide groove 35, the sliding frame 39 will vibrate up and down during the sliding process. On the one hand, the first filter screen 5 and the second filter screen 6 are knocked by the up and down vibration. On the other hand, the up and down vibration process will generate an interval between the first filter screen 5 and the second filter screen 6, which is convenient for the accumulated mud to pass through the push plate 40. After the push plate 40 floats up and down, the top of the mud also presents a wavy shape.

[0028] It is worth noting that Figure 8 As shown, trapezoidal chutes 36 are provided at both ends of the wave chute 35. When the filter mesh holes are small and the mud filtering efficiency is low, a large amount of mud is accumulated. After spreading the material, the push plate 40 has reached the edge of the filter mesh, and some mud is still accumulated on the push plate 40. The push plate 40 is lifted higher by the trapezoidal chute 36, and then lowered and returned to slide to the other side edge of the filter mesh, so that the excess mud can be spread to the other side.

[0029] In addition, if Fig. 9 and Fig.10 As shown, a flushing rack 25 is provided below the sliding rack 39. When the sliding rack 39 floats up and down, the third piston tube 42 is driven to move up and down. When the sliding rack 39 moves up, the third piston rod 43 moves toward the inside of the third piston tube 42, and presses the water in the third piston tube 42 into the flushing rack 25 to flush the filter below. When the sliding rack 39 moves down, the third piston rod 43 moves upward to the outside of the third piston tube 42, and draws external water through the liquid inlet pipe 46. The water source is the same as mentioned above, and uses clean water separated from mud to achieve the purpose of recycling.

[0030] A method for treating a polluted soil mixture resource treatment system, comprising the following steps: S1: Slurry the slag to obtain mud, and transport the obtained mud to the feed box 13, start the first motor 11 and the second motor 21, the second motor 21 drives the two first magnetic rollers 15 to rotate, and removes the metal debris in the passing mud. Then, the first motor 11 reciprocates the vibration frame 10 through the cam 12 to achieve continuous vibration of the screening box 4, and the mud is screened through the first filter screen 5 and the second filter screen 6; S2: Start the driving motor to drive the reciprocating screw rod 44 to rotate, drive the slide plate 41 and the sliding frame 39 to slide back and forth, and under the guidance of the wave slide 35, the sliding frame 39 reciprocates up and down to spread the mud accumulated on the first filter screen 5 and the second filter screen 6. In the process of the sliding frame 39 vibrating up and down, the external water is guided into the flushing frame 25 to flush the filter holes; S3: The second magnetic roller 23 in the magnetic separation frame 22 is driven by gears to reciprocate and magnetically separate the passing slurry again.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
