DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0025] The following is combined with Figure 1 To the attached Figure 3 And specific embodiments discuss the present invention in detail.

[0026] like Figures 1 to 3 As shown, the present invention provides an apparatus for re-extracting iron-containing powder from waste tailings, comprising a first cyclone body 1. The overflow port at the top of the first cyclone body 1 is fixedly connected to a first overflow pipe 11. The inlet of the first cyclone is fixedly connected to a feed pipe 12. The end of the feed pipe 12 remote from the first cyclone body 1 is fixedly connected to a hopper 13. Water is added to the waste tailings in advance to form a tailings slurry. The tailings slurry is then added to the hopper 13. The tailings slurry in the hopper 13 enters the first cyclone body 1 through the feed pipe 12.

[0027] The bottom flow outlet at the bottom of the first cyclone body 1 is fixedly connected to a first discharge pipe 14 , below which a stirring barrel 2 is provided. Impurities in the tailings slurry inside the first cyclone body 1 are discharged through the first overflow pipe 11 , and the iron powder-containing material falls into the stirring barrel 2 through the first discharge pipe 14 at the bottom.

[0028] A water supply pipe 21 is fixedly connected to the top upper surface of the mixing barrel 2. The water supply pipe 21 is connected to a water source (not shown in the figure). Water is added to the mixing barrel 2 through the water supply pipe 21 to dilute the iron powder material inside the mixing barrel 2.

[0029] A second cyclone body 3 is provided next to the mixing barrel 2. The feed port of the second cyclone body 3 is fixedly connected to a feed pipe 4. The end of the feed pipe 4 away from the second cyclone body 3 is inserted into the mixing barrel 2. A delivery pump body 41 is fixedly connected to the feed pipe 4. A support base 411 is fixedly connected to the bottom of the delivery pump body 41. The support base 411 supports the delivery pump body 41. The delivery pump body 41 delivers the diluted iron powder material slurry in the mixing barrel 2 to the second cyclone body 3 through the feed pipe 4.

[0030] The overflow port at the top of the second cyclone body 3 is fixedly connected to a second overflow pipe 31, and the underflow port at the bottom of the second cyclone body 3 is fixedly connected to a second discharge pipe 32. A disc filter body 5 is located adjacent to the second cyclone body 3. The end of the second discharge pipe 32, remote from the second cyclone body 3, is fixedly connected to the inlet of the disc filter body 5.

[0031] Impurities in the slurry inside the second cyclone body 3 are discharged through the second overflow pipe 31, and the iron-containing powder material falls into the disc filter body 5 through the second discharge pipe 32 at the bottom for solid-liquid separation. The iron content in the iron-containing powder material discharged through the second overflow pipe 31 is further increased.

[0032] A material discharge port 51 is provided on one side of the disc filter body 5. The iron-containing powder material after solid-liquid separation is discharged through the material discharge port 51. The iron-containing powder material discharged from the material discharge port 51 is collected and can be used as raw material for steel plant production, thereby improving material utilization, reducing material waste, and improving the comprehensive utilization rate of resources.

[0033] A conveyor belt 6 is provided below the material drop opening 51 . After the iron-containing powder material leaves the material drop opening 51 , it falls onto the conveyor belt 6 . The conveyor belt 6 collects and transports the iron-containing powder material.

[0034] An impurity collection box 7 is provided below the first overflow pipe 11 and the second overflow pipe 31. Impurities in the first overflow pipe 11 and the second overflow pipe 31 fall into the impurity collection box 7 for temporary storage. An impurity drop pipe 71 is fixedly connected to the bottom of the impurity collection box 7. A solenoid valve 711 is fixedly installed on the impurity drop pipe 71. When the impurities in the impurity collection box 7 need to be transported by a transport vehicle, the solenoid valve 711 is opened, and the impurities in the impurity collection box 7 fall through the impurity drop pipe 71 into the transport vehicle, which transports the impurities. After the impurities are dropped, the solenoid valve 711 is closed.

[0035] A vibration motor 72 is fixedly connected to the bottom of the outer wall of the impurity collection box 7. When impurities are dropped through the impurity dropping pipe 71, the vibration motor 72 works. When the solenoid valve 711 is closed and impurities are no longer needed to be dropped, the vibration motor 72 stops working. The vibration motor 72 reduces the possibility of impurities clogging the impurity dropping pipe 71 during the falling process.

[0036] The stirring barrel 2 is connected to a stirring assembly 8 , which stirs the diluted iron-containing powder material in the stirring barrel 2 so that the iron-containing powder material and water are mixed more fully.

[0037] The stirring assembly 8 includes a fixed plate 81 fixedly connected to the upper surface of the mixing barrel 2. A drive motor 82 is fixedly connected to the upper surface of the fixed plate 81. The output shaft of the drive motor 82 is disposed through the fixed plate 81. The output shaft of the drive motor 82 is fixedly connected to a vertically arranged rotating rod 83. A plurality of stirring rods 84 are fixedly connected to the vertical side walls of the rotating rod 83. The output shaft of the drive motor 82 drives the rotating rods 83 to rotate, and the rotating rods 83 drive the stirring rods 84 to rotate. The stirring rods 84 stir the iron powder material in the mixing barrel 2.

[0038] The present invention provides an apparatus for re-extracting iron-containing powder from waste tailings. The principle of operation is as follows: tailings slurry is added to a hopper 13. The tailings slurry in the hopper 13 enters the first cyclone body 1 through a feed pipe 12. Impurities in the tailings slurry in the first cyclone body 1 are discharged through a first overflow pipe 11, and the iron-containing powder falls into the mixing barrel 2 through a first discharge pipe 14 at the bottom. A water supply pipe 21 replenishes water into the mixing barrel 2 to dilute the iron-containing powder inside the mixing barrel 2. A stirring rod 84 stirs the iron-containing powder inside the mixing barrel 2. The delivery pump delivers the diluted iron-containing powder material slurry in the mixing barrel 2 to the second cyclone body 3 through the feed pipe 4. Impurities in the slurry inside the second cyclone body 3 are discharged through the second overflow pipe 31. The iron-containing powder material falls into the disc filter body 5 through the second discharge pipe 32 at the bottom for solid-liquid separation. The iron-containing powder material after solid-liquid separation is discharged through the material discharge port 51, and the iron-containing powder material discharged from the material discharge port 51 is collected.

[0039] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
