DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0019] As shown in Figures 1 to 3 A pre-desliming dust-settling downer for assisting photoelectric sorting effect, comprising a downer 2 arranged above a vibrating cloth screen 1, the downer 2 is in a vertical cylinder shape, a supporting leg is welded to the lower end of the downer 2, a feeding port 3 is arranged on the left side of the downer 2, the tail end of a raw ore conveying belt 4 extends into the downer 2 through the feeding port 3, and a discharge port 5 is arranged at the bottom of the downer 2. The raw ore conveying belt 4 conveys phosphorite to be deslimed and dust-settled into the downer 2, and then the phosphorite falls onto the screen plate 6 of the vibrating cloth screen 1 through the discharge port 5 at the bottom of the downer 2.

[0020] The top of the discharging bin 2 is connected with a dust collector 7 through a pipeline. A water supply pipe 8 is fixedly installed on the front and rear side walls and left and right side walls of the discharging bin 2 above the feeding port 3. A plurality of filter plates 9 are welded on the left and right side walls of the discharging bin 2 below the feeding port 3, and the filter plates 9 are provided with filter holes for slurry to pass through. The filter plates 9 are vertically and uniformly spaced, and the filter plates 9 on the left and right side walls of the discharging bin 2 are staggered. The end of the filter plate 9 away from the corresponding side wall of the discharging bin 2 is arranged in a downward and inclined manner. The lower filter plate 9 receives the mineral material falling from the upper filter plate 9.

[0021] When the phosphate ore enters the discharging bin 2 through the raw ore conveying belt 4, the phosphate ore first falls onto the uppermost filter plate 9 and then rolls onto the filter plate 9 below along the uppermost filter plate 9. The phosphate ore successively rolls on the plurality of filter plates 9 and finally falls downward through the discharge port 5 to the screen plate 6 of the vibrating distributing screen 1.

[0022] The side wall of the discharging bin 2 is fixedly installed with a flushing pipe 10 for flushing the mineral material on the filter plate 9. The flushing pipe 10 corresponds to the filter plate 9 one by one. The outlet end of the flushing pipe 10 is located at the top of the corresponding filter plate 9, and the outlet end of the flushing pipe 10 is fixedly installed with a spray head 11. The spray head 11 is perpendicular to the filter plate 9 and directly sprays the mineral material falling from the conveying belt or the upper filter plate. The inlet end of the flushing pipe 10 is connected with the water inlet pipe 22 and the air blowing pipe 23 through valves.

[0023] In the rainy season, when the surface of the phosphate ore entering the discharging bin 2 is adhered with mud, the water supply pipe 8 and the flushing pipe 10 and the water inlet pipe 22 are opened to spray and flush the phosphate ore entering the discharging bin 2. The mud on the surface of the phosphate ore is washed away through repeated spraying and flushing during the rolling process of the phosphate ore on the plurality of filter plates 9. The sprayed slurry falls through the screen plate 6 of the vibrating distributing screen 1. The phosphate ore sprayed clean is washed by the water sprayed by the spray head 11 and falls along the screen plate 6 to the photoelectric ore dressing machine for separation. The water source for flushing the phosphate ore can be rainwater collected in a rainwater collection pool. After flushing the phosphate ore, the water falls through the screen holes of the screen plate 6 and is collected for other processes or photoelectric ore dressing desliming for recycling, thereby reducing resource consumption.

[0024] A plurality of perforated plates 12 are movably installed in the lower hopper 2 between the water delivery pipe 8 and the feed inlet 3. A strip-shaped hole 13 is formed in the left side wall of the lower hopper 2 for drawing out the perforated plate 12. A support strip 14 is welded to the inner side of the front and rear side walls of the lower hopper 2 for supporting the perforated plate 12. A first blocking plate 15 is welded to the left end of the perforated plate 12 and located outside the lower hopper 2. When the perforated plate 12 is completely inserted into the lower hopper 2, the first blocking plate 15 blocks the strip-shaped hole 13. A handle is provided on the left side of the first blocking plate 15. In addition, a baffle 16 is movably installed in the lower hopper 2 above the perforated plate 12. A long strip-shaped hole 17 is formed in the left side wall of the lower hopper 2 for drawing out the baffle 16. A support plate 18 is welded to the inner side of the front and rear side walls of the lower hopper 2 for supporting the baffle 16. A second blocking plate 19 is welded to the left end of the baffle 16 and located outside the lower hopper 2. When the baffle 16 is completely inserted into the lower hopper 2, the second blocking plate 19 blocks the long strip-shaped hole 17. A handle is provided on the left side of the second blocking plate 19.

[0025] When the phosphate ore is washed through the flushing pipe 10, the baffle 16 and the perforated plate 12 are installed in the lower hopper 2. The water entering the lower hopper 2 through the flushing pipe 10 falls in the form of raindrops through the perforated plate 12, thereby improving the washing effect on the phosphate ore.

[0026] In addition, when there is no rain or the phosphate ore entering the lower hopper 2 is dry and covered with dust on the surface, the baffle 16 and the perforated plate 12 are drawn out of the lower hopper 2. The dust collector 7 is started, the valve on the water inlet pipe 22 is closed, and the valve on the air blowing pipe 23 is opened. Compressed air is sent through the air blowing pipe 23, the flushing pipe 10 and the spray head 11. The compressed air blows the dust on the surface of the phosphate ore on the filter plate 9, and the dust diffused in the lower hopper 2 is sucked away by the dust collector. The pre-dusted phosphate ore enters the photoelectric separator for separation.

Those skilled in the art should understand that the present application is not limited to the above examples. The above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
