Embodiment 1
[0028] A shaking bed used for vanadium-containing stone coal beneficiation to pre-enrich vanadium. like figure 1 As shown, the shaker consists of a bed surface 4 , a support mechanism 6 , a slope adjustment mechanism 5 and a transmission mechanism 1 . The bed surface 4 is installed on the supporting mechanism 6, there are three supporting mechanisms 6, and the supporting mechanisms 6 are parallel to each other.
[0029] The bed surface 4 of this embodiment is as follows figure 2 As shown, it includes a roughing table 9, a checking table 8 and a sweeping table 7. On the bed surface 4, one end of the ore feeding groove 2 and the water feeding groove 3 is the ore feeding end, the end facing the ore feeding end is the concentrate end, and the end facing the transmission mechanism is the tailing end.
[0030] like figure 2 As shown, the sweeping bed 7 is located at the tailings end of the bed 4, the outline of the sweeping bed 7 is a right triangle, and the hypotenuse of the ...
Embodiment 2
[0036] A shaking bed used for vanadium-containing stone coal beneficiation to pre-enrich vanadium. Except the following technical parameters, all the other are the same as in Example 1:
[0037]Both the roughing bed surface 9 and the reselecting bed surface 8 are equipped with 10-11 bed strip groups 12; the pinch-out angle of the bed surface 4 is 40-50 o The slope of the re-selected bed surface 8 is 1-1.5%; the slope of the steep slope bed 11 is 200-240%; the slope of the gentle slope 10 is 45-55%; the roughness of the sweeping bed 7 is 75-85 μm ; The roughness of the roughing bed surface 9 and the re-selecting bed surface 8 is 50-70 μm.
Embodiment 3
[0039] The utility model relates to a shaker for pre-enrichment of vanadium in vanadium-containing stone coal beneficiation. Except following technical parameter, all the other are with embodiment 1:
[0040] Both the rough selection bed surface 9 and the double selection bed surface 8 are equipped with 13~20 bed strip groups 12; the pinch-out angle of the bed surface 4 is 35~45° o The slope of the re-selected bed surface 8 is 1.5-2%; the slope of the steep slope bed 11 is 235-275%; the slope of the gentle slope 10 is 50-58%; the roughness of the sweeping bed 7 is 80-90 μm ; The roughness of the roughing bed surface 9 and the re-selecting bed surface 8 is 55-75 μm.
[0041] This specific embodiment is used in the process of vanadium-containing stone coal beneficiation and pre-enrichment of vanadium, so that the horizontal water flow will arouse a high-intensity eddy current when the roughing bed surface 9 crosses the steep slope bed strip 11, forming a relatively large ascend...
