Description

Technical Field

[0001] The utility model relates to the technical field of tailings separation equipment, in particular to a secondary tailings slurry separator. Background Art

[0002] The tailings produced by copper smelting, also known as copper slag or copper smelting tailings, are waste slag containing iron, silicon, aluminum, calcium and other substances produced in the process of pyrometallurgical copper smelting. In the above-mentioned waste slag treatment process, the waste slag will be treated by a jig. The jig can efficiently recover the metal copper particles in the tailings, especially the copper smelting slag with uneven coarseness and fineness. The recovery rate of copper can be significantly improved through the treatment of the jig.

[0003] Since part of the waste residue treated by the jigger uses water as a medium, it is necessary to separate the generated slag slurry after the waste residue is screened. The usual practice is to discharge the slag slurry discharged from the jigger directly into the sedimentation tank, so that the slag material is precipitated and the water is discharged through the overflow port or overflow pipe of the upper layer of the sedimentation tank. For example, the Chinese utility model patent disclosed by the existing publication number CN218046620U: a sedimentation device for silicon-manganese filter residue treatment, in which the semi-solid ore liquid is inverted, and the gathered large pieces of ore and slag are revealed, and the sedimentation pot is raised to a height convenient for the ore liquid through a lifting device, and the rope is tightened by a winch to make the bottom of the sedimentation pot turn up, and the sedimentation pot is in a tilted state, which is convenient for pouring out the semi-solid ore liquid. However, this operation mode cannot make the slag sifted by the jigger enter the sedimentation pot for sedimentation when the sedimentation pot is lifted and turned over, so that the sedimentation and separation efficiency of the entire slurry is not high.

A second bevel gear 22 is fixedly installed on the side of the rotating shaft 21 away from the runner 15. The rotating shaft 21 extends into the frame 8 through the shaft seat on one side of the frame 8, and the second bevel gear 22 is meshed with the first bevel gear 11. When one side of the rotating shaft 21 is meshed with the first bevel gear 11 through the second bevel gear 22, the runner 15 can be driven to rotate synchronously when the screw conveying paddle 7 is driven, thereby reducing energy consumption. A gear block group 23 is fixedly installed on one side of the top, a bracket 24 is fixedly installed on the side of the reciprocating frame 16 away from the gear block group 23, a cylinder 25 is fixedly installed on one side of the bracket 24, and the cylinder 25 is connected to an external air pump through a pipeline, and multiple push shafts 20 on one side of the rotating wheel 15 are meshed and connected with the corresponding gear block group 23, so as to drive the reciprocating frame 16 to reciprocate between the side plate 13 and the two L-shaped limit bars 14, and because the first bevel gear 11 drives the two second bevel gears 22 in different directions, that is, when the push shaft 20 on one side of one of the rotating wheels 15 drives the gear block group 23 at the bottom of one of the reciprocating frames 16, the other rotating wheel 15 drives the push shaft 20 at the top of the other reciprocating frame 16 through the push shaft 20 on one side, thereby realizing the synchronous reciprocating motion of the two reciprocating frames 16.

[0029] It should be noted that the utility model is a secondary tailings slurry separation. After the slurry discharged by the jig enters the sedimentation tank 1, the heavier slag settles to the bottom of the sedimentation tank 1, and the slurry overflows through the multiple overflow pipes 3 at the upper outer side of the sedimentation tank 1. After the slag in the sedimentation tank 1 has settled and accumulated for a period of time, the motor 9 can be started. The motor 9 drives the screw conveyor paddle 7 to rotate in the lifting pipe 6 through the transmission shaft 10, so that the screw conveyor paddle 7 lifts the slag at the bottom of the sedimentation tank 1 through the pipe opening at the lower end of the lifting pipe 6, and with the help of the porous metal mesh structure of the lifting pipe 6, the slag is drained when it is lifted. After the slag is lifted into the discharge hopper 5 by the screw conveyor paddle 7, it is discharged through the discharge channel on one side of the lifting pipe 6. The slag is discharged into the discharge hopper 5, and because the slag still has a certain humidity, part of the slag will adhere to the bottom of the discharge hopper 5, thereby affecting the normal discharge of the discharge hopper 5. At this time, since the motor 9 drives the screw conveyor 7 through the transmission shaft 10, and the transmission shaft 10 synchronously drives the first bevel gear 11 to rotate, the first bevel gear 11 is meshed and connected with the two second bevel gears 22, thereby synchronously driving the two second bevel gears 22 to rotate, and then the two second bevel gears 22 respectively drive the rotating shaft 21 to rotate, so that the two rotating shafts 21 respectively drive the rotating wheels 15 on one side to rotate, and because the first bevel gear 11 drives the two second bevel gears 22 to rotate in different directions, that is, the push shaft 20 on one side of one of the rotating wheels 15 drives one of the reciprocating frames When the tooth block group 23 at the bottom of the rotating wheel 15 is moved, the other rotating wheel 15 drives the push shaft 20 at the top of the other reciprocating frame 16 through the push shaft 20 on one side thereof, thereby realizing the synchronous reciprocating motion of the two reciprocating frames 16. As a result, the two reciprocating frames 16 synchronously drive the two sliding bars 17 on one side and the bracket 24 on the other side to move, and the bracket 24 drives the cylinder 25 to move synchronously, so that the two sliding bars 17 drive the multiple lifting rods 18 to move synchronously through the multiple guide shafts 26 on one side, so that the push plate 19 between the two lifting rods 18 pushes the slag in the discharge hopper 5 to one side for discharge, and when the multiple push shafts 20 on one side of the rotating wheel 15 rotate to the position of the other tooth block group 23, the reciprocating frame 16 is moved between the side plate 13 and the L-shaped The limit stop bar 14 moves back, so, synchronously, the cylinder 25 is started, and the output end of the cylinder 25 lifts the corresponding top plate 28, so that the top plate 28 synchronously drives the three lifting rods 18 to lift through the connecting rod 27, and the guide groove 29 on one side of the lifting rod 18 slides on the corresponding guide shaft 26, so that the lifting rod 18 drives the push plate 19 to lift, that is, the lifting rod 18 and the push plate 19 will not push the slag in the discharge hopper 5 back when they are reset. When the push plate 19 moves to the initial position, the output end of the cylinder 25 drives the top plate 28 to move downward, that is, the top plate 28 cooperates with the connecting rod 27 to synchronously drive the three lifting rods 18 to move downward and drive the push plate 19 to move downward, and the above-mentioned reciprocating operation can be repeated.
