When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] Please combine Figures 1 to 4 As shown, this utility model provides a tailings sand and gravel recovery device. The recovery device includes a fixed cylinder 1 and a sorting cylinder 2 fixedly installed inside the fixed cylinder 1. Part of the sorting cylinder 2 is located outside the fixed cylinder 1. The sorting cylinder 2 located outside the fixed cylinder 1 is provided with a discharge port. An inlet pipe 14 is fixedly installed on the end of the sorting cylinder 2 away from the discharge port. The tailings are transported to the interior of the sorting cylinder 2 by a pump. The sorting cylinder 2 located inside the fixed cylinder 1 is provided with multiple screen hole areas 6. The multiple screen hole areas 6 are arranged sequentially along the length direction of the sorting cylinder 2. The screen hole areas 6 closer to the discharge port have larger filter holes. The filter holes in the same screen hole area 6 are the same size. Only sand and gravel of the same size can pass through the same screen hole area 6.
[0027] A shaft 3 is rotatably mounted inside the sorting cylinder 2. A spiral blade 4 is fixedly mounted on the outer surface of the shaft 3. A motor 5 is fixedly mounted on the outer surface of the fixed cylinder 1. The output end of the motor 5 is fixedly connected to one end of the shaft 3. A gap is provided on the outer side of the shaft 3 in each screen hole area 6. Multiple flaps 9 are provided on the outer surface of the shaft 3 in the gap. The multiple flaps 9 are evenly distributed in the circumferential direction of the shaft 3. Each flap 9 is fixedly connected to the shaft 3 through a connecting rod 10.
[0028] The feed pipe 14 transports the tailings into the interior of the sorting cylinder 2. The rotating spiral blades 4 can push the tailings to the screen area 6. Multiple screen areas 6 sort the tailings in sequence. The tailings entering the gap will be flipped by multiple rotating flaps 9 to ensure that the tailings can be screened more fully and to avoid the tailings in multiple screen areas 6 not being completely sorted, thus affecting the sorting effect.
[0029] Both the fixed cylinder 1 and the sorting cylinder 2 are set to an inclined state. The tailings in the gap can move towards the next screen hole area 6 by gravity, avoiding the problem of excessive tailings accumulating in the gap and causing a decrease in the sorting effect. Multiple blocking rings 12 are fixedly installed on the inner surface of the sorting cylinder 2 at each gap. Each flap 9 has a notch 11. The blocking rings 12 have the function of preventing the tailings from moving to the next screen hole area 6, which can increase the time the tailings stay in the gap. As the flap 9 is rotated to continuously flip the tailings, after the height of the tailings is increased, some of the tailings can pass over the blocking rings 12 smoothly, thus ensuring that the tailings can move smoothly towards the discharge port.
[0030] A separator ring 8 is fixedly installed between the fixed cylinder 1 and the sorting cylinder 2. The separator ring 8 is located at the junction of the two screen hole areas 6 to separate sand and gravel of different sizes that enter the fixed cylinder 1. A discharge port 13 is provided on the fixed cylinder 1, and the sand and gravel in the fixed cylinder 1 are discharged into the interior of the fixed cylinder 1 through the discharge port 13.
[0031] A collection trough 15 is provided directly below the fixed cylinder 1. A partition plate 16 is fixedly installed on the inner surface of the collection trough 15. The partition plate 16 separates the sand and gravel sorted by different screen areas 6. The top of the partition plate 16 is fixedly connected to the fixed cylinder 1. The partition plate 16 is located at the junction of two screen areas 6. A filter plate 17 is fixedly installed on the inner surface of the collection trough 15. A cavity is formed between the filter plate 17 and the inner bottom surface of the collection trough 15. A water outlet pipe is fixedly installed on the collection trough 15 and is connected to the cavity. The collection trough 15 collects the recovered sand and gravel. The collected sand and gravel contains a lot of water. The filter plate 17 can remove the water and discharge it through the water outlet pipe.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
