[0002] Tailings treatment is a crucial step in the mining industry. With the increasing scarcity of mineral resources and increasing environmental protection requirements, the efficient and environmentally friendly recycling of useful components in tailings has become a key focus of the industry. Traditional tailings recovery equipment typically uses a relatively simple feeding method, which results in excessively fast material flow and uneven distribution when entering the magnetic separation equipment. This affects the separation effect during subsequent processing, preventing some iron-containing ore from being magnetically separated and reducing the recovery rate. To this end, we propose a uniform tailings sand feeding mechanism. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0019] See also Figures 1-4 The utility model provides a technical solution: a tailings sand uniform discharge mechanism, comprising an inclined discharge conveyor belt 1, and a plurality of groups of support columns 2 are symmetrically arranged on both sides of the discharge conveyor belt 1. The discharge conveyor belt 1 adopts a conveyor belt conveyor commonly used in the prior art, and adopts an inclined discharge conveyor belt 1 to discharge and transport the tailings sand. The discharge speed is adjusted by controlling the conveying speed of the discharge conveyor belt 1 to prevent the tailings sand from entering the magnetic separation equipment too fast and affecting the recovery rate.

[0020] A fixed baffle 8 parallel to the unloading conveyor belt 1 is fixed on the top of the support column 2. The fixed baffle 8 is symmetrically arranged on both sides of the feeding direction of the unloading conveyor belt 1 to block the tailings sand on the unloading conveyor belt 1 to prevent it from sliding from both sides of the unloading conveyor belt 1 to the outside during the unloading process.

[0021] An adjustable leveling plate 3 is provided on the fixed baffle 8. The bottom end of the leveling plate 3 is set on the upper side of the unloading conveyor belt 1 and scrapes the tailings sand on the unloading conveyor belt 1 evenly. When the tailings sand is transported on the unloading conveyor belt 1, it is scraped evenly by the leveling plate 3 when passing under it, so that the tailings sand is more evenly distributed and it is easier to magnetically separate the iron-containing tailings by the magnetic separation equipment, thereby improving the separation effect and recovery rate in the subsequent processing process.

[0022] Preferably, the uniform material plate 3 can be adjusted in height, so as to flexibly adjust according to different tailings and magnetic separation recovery requirements, and improve the universality of the mechanism. Specifically, two fixed baffles 8 are symmetrically provided with two guide rods 4, and the two side surfaces of the uniform material plate 3 are symmetrically provided with two adjusting blocks 5. The upper surface of the adjusting block 5 is provided with a guide hole, the adjusting block 5 passes through the guide hole and the guide rod 4, and the uniform material plate 3 slides up and down on the guide rod 4 through the adjusting block 5, so as to adjust the distance between the bottom end of the uniform material plate 3 and the discharging conveying belt 1. The outer surface of the adjusting block 5 is provided with a screw hole in communication with the guide hole, and a fixed bolt 6 is threadedly connected in the screw hole. The position of the adjusting block 5 is fixed by tightening the fixed bolt 6, and the height of the uniform material plate 3 is fixed. The operation is simple and convenient to adjust.

[0023] Further preferably, the two side surfaces of the uniform material plate 3 are provided with scale lines 7, and the height of the uniform material plate 3 can be accurately adjusted according to the scale lines 7.

[0024] Preferably, the two fixed baffles 8 are symmetrically provided with discharge ports near the uniform material plate 3, and the discharge ports are hingedly provided with movable baffles 9. When too much tailings accumulate in front of the uniform material plate 3, the movable baffles 9 can be opened to discharge the excess tailings through the discharge ports, avoiding affecting the overall discharging and subsequent magnetic separation.

[0025] Specifically, the upper surface of the movable baffle 9 is provided with a sliding groove 10, and a sliding block is slidably arranged in the sliding groove 10. The upper surface of the sliding block is rotatably provided with a first rotating block 11, and the upper surface of the fixed baffle 8 near the free end of the movable baffle 9 is rotatably provided with a second rotating block 12. A telescopic rod 13 is arranged between the first rotating block 11 and the second rotating block 12. When the tailings accumulated near the uniform material plate 3 on the discharging conveying belt 1 become more, the tailings will be extruded to both sides, thereby pushing the movable baffle 9 outward. When the movable baffle 9 is opened outward, the whole movable baffle 9 rotates around the hinged end, and the free end moves outward, so that the sliding block slides in the sliding groove 10 while driving the first rotating block 11 and the second rotating block 12 to rotate, and the telescopic rod 13 is lengthened to open the discharge port. The tailings accumulated on the discharging conveying belt 1 can be discharged from the discharge port.

[0026] A further preferred technical solution is that the telescopic rod 13 includes a fixed rod and a sliding rod, one end of the fixed rod is fixedly arranged on the outside of the second rotating block 12, and the other end of the fixed rod is provided with a groove, and a spring is installed in the groove, and the end of the spring is fixedly connected to one end of the sliding rod, and the sliding rod is slidably arranged in the groove, and the other end of the sliding rod is fixedly connected to the outer surface of the first rotating block 11. When the movable baffle 9 is squeezed by the tailings and opened, the telescopic rod 13 is stretched as a whole, and the sliding rod moves outward and stretches the spring. After discharging excess tailings, the pressure on the movable baffle 9 becomes smaller, and under the action of the spring tension, the sliding rod is automatically pulled back into the groove and reset, thereby driving the movable baffle 9 to reset to the closed discharge port, thereby realizing the function of automatically discharging excess tailings and automatically resetting after discharge, which is more convenient to use.

[0027] An optional technical solution is that a receiving box 14 is provided under the movable baffle 9 of the unloading conveyor belt 1, the upper surface of the receiving box 14 is open, and one of the side surfaces of the receiving box 14 is provided with a discharge port, and the receiving box 14 is used to receive the accumulated tailings sand discharged from the discharge port, and these tailings sand are sent to an external feeding device such as a spiral elevator or a feeding conveyor belt through the discharge port, and then sent back to the unloading conveyor belt 1 from the feeding device to continue unloading and magnetic separation and other operations.

[0028] Further optionally, a slope 15 is provided on the inner upper surface of the receiving box 14, and the slope 15 is inclined downward toward the discharge port, so that the tailings sand falling into the receiving box 14 can slide out of the discharge port along the slope 15 under the action of gravity and enter the feeding equipment.

[0029] Furthermore, a convergence portion 16 is provided on the inner side of the receiving box 14 near the discharge port, and the convergence portion 16 is inclined inward so that the width of the discharge port is smaller than the width inside the receiving box 14, so that the tailings sand discharged from the discharge port is more concentrated and less spilled, which is suitable for situations where the inlet of the feeding equipment is smaller.

[0030] The undisclosed parts of the present invention are all prior art, and their specific structures, materials and working principles will not be described in detail. Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
