DETAILED DESCRIPTION
[0013] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] like Figure 1 As shown, a device for magnetic tailings classification comprises a classification drum 1, a stirring shaft 2, heavy-grade tailings stirring blades 3, medium-grade tailings stirring blades 4 and light-grade tailings stirring blades 5; the bottom plate of the classification drum 1 is an inclined structure, a heavy-grade tailings discharge port 6 is arranged at the lowest point of the bottom plate of the classification drum 1, and a magnetic tailings slurry inlet 7 is arranged on the top plate of the classification drum 1; the stirring shaft 2 is vertically arranged at the center of the classification drum 1; the heavy-grade tailings stirring blades 3, medium-grade tailings stirring blades 4 and light-grade tailings stirring blades 5 are arranged on the stirring shaft 2 in sequence from bottom to top; a medium-grade tailings discharge port 8 is arranged on the classification drum 1 at the horizontal height position of the medium-grade tailings stirring blades 4; a light-grade tailings discharge port 9 is arranged on the classification drum 1 at the horizontal height position of the light-grade tailings stirring blades 5.
[0015] The heavy tailings stirring blades 3 are located at a quarter of the length of the stirring shaft 2, the angle between the extension direction of the heavy tailings stirring blades 3 and the stirring shaft 2 is 90°, and the number of the heavy tailings stirring blades 3 is 2 to 5 and is evenly distributed along the circumferential direction.
[0016] The medium-sized tailings stirring blades 4 are located at half the length of the stirring shaft 2, the medium-sized tailings stirring blades 4 are inclined downward, the angle between the extension direction of the medium-sized tailings stirring blades 4 and the stirring shaft 2 is 45°, and the number of the medium-sized tailings stirring blades 4 is 2 to 5 and is evenly distributed along the circumferential direction.
[0017] The light-grade tailings stirring blades 5 are located at three-quarters of the length of the stirring shaft 2, the light-grade tailings stirring blades 5 are inclined downward, the angle between the extension direction of the light-grade tailings stirring blades 5 and the stirring shaft 2 is 30°, and the number of the light-grade tailings stirring blades 5 is 2 to 5 and is evenly distributed along the circumferential direction.
[0018] The top end of the stirring shaft 2 is connected to a stirring driving mechanism, which is arranged on the lifting and adjusting mechanism. The stirring shaft 2 is driven to rotate by the stirring driving mechanism, and the stirring shaft 2 is driven to adjust the height up and down by the lifting and adjusting mechanism. Specifically, the stirring driving mechanism can be a motor-driven stirring driving mechanism, and the lifting and adjusting mechanism can be a hydraulically driven lifting and adjusting mechanism.
[0019] The following describes a one-time use process of the present invention in conjunction with the accompanying drawings:
[0020] First, the magnetic separation tailings slurry is sent into the classification drum 1 from the magnetic separation tailings slurry inlet 7, and then the stirring drive mechanism is started to drive the stirring shaft 2 to rotate, and then the heavy-grade tailings stirring blades 3, medium-grade tailings stirring blades 4 and light-grade tailings stirring blades 5 are driven to rotate synchronously. Under the dual effects of rotary stirring and gravity sedimentation, the heavy-grade tailings will gradually sink to the bottom of the classification drum 1, the medium-grade tailings will sink to the upper layer of the heavy-grade tailings, and the light-grade tailings will float to the upper layer of the medium-grade tailings. The upper layer of the light-grade tailings is the water layer.
[0021] After the heavy-grade tailings, medium-grade tailings and light-grade tailings have completed sedimentation and stratification, the light-grade tailings discharge port 9 is opened first, and the light-grade tailings and water layers can be discharged from the grading cylinder 1 first, thereby achieving the grading of the light-grade tailings.
[0022] After the light-grade tailings and water are separated and discharged from the classification cylinder 1, the medium-grade tailings discharge port 8 is opened to discharge the medium-grade tailings from the classification cylinder 1, thereby achieving the classification of the medium-grade tailings.
[0023] After the medium-sized tailings are discharged from the grading cylinder 1, the heavy-sized tailings discharge port 6 is finally opened to discharge the heavy-sized tailings from the grading cylinder 1, thereby achieving the grading of the heavy-sized tailings. Since most of the water in the tailings has been discharged along with the light-sized tailings and the medium-sized tailings when they are discharged, when the heavy-sized tailings are discharged, they are equivalent to the concentrated heavy-sized tailings.
[0024] In addition, according to the characteristics of the magnetic separation tailings slurry, the rotation speed and the up and down lifting height of the stirring shaft 2 can also be appropriately adjusted to optimize the classification efficiency of heavy-grade tailings, medium-grade tailings and light-grade tailings.
[0025] The solutions in the embodiments are not intended to limit the protection scope of the present invention. All equivalent implementations or changes that do not deviate from the present invention are included in the protection scope of the present invention.
