Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of manganese nodule collection equipment, and in particular to a gravity-type multi-stage ore sand separation device. Background Technology
[0002] During the mining process, manganese nodules inevitably have seabed sediment particles and soft or hard clay adhering to their surface. Therefore, when collecting manganese nodules, it is easy to recover the nodules along with the adhering material on their surface. This can cause the recovered material to clog the recovery pump pipes, resulting in damage to the pump pipes. In addition, the extra collected material increases the weight and occupies storage space, thereby reducing the collection efficiency. Utility Model Content
[0003] In response to the current mining process, which often results in the recovery of manganese nodules along with their surface deposits, leading to damage to the recovery pump pipes, occupying storage space, and reducing collection efficiency, this utility model provides a gravity-type multi-stage mineral sand separation device.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a gravity-type multi-stage ore sand separation device includes a first separation component and a second separation component. The first separation component and the second separation component each have a pipe, a screen and a pusher. The second separation component is connected to the first separation component. An inclined discharge pipe is connected to one side of the second separation component.
[0005] Furthermore, the first separation component includes a first separation tube, and the second separation component includes a second separation tube and a third separation tube. The second separation tube and the third separation tube are both connected to the bottom of the first separation tube, and the second separation tube is located in front of the third separation tube.
[0006] Furthermore, a funnel-shaped collection port is fixedly connected to the front end of the first separation tube.
[0007] Furthermore, the second and third separation pipes are connected to the middle of the first separation pipe, and a first screen and a first pusher are provided in the rear part of the first separation pipe. The first pusher pushes the water flow along the first separation pipe from the inside to the outside.
[0008] Furthermore, both the second and third separation tubes are connected to the first separation tube in an inclined manner.
[0009] Furthermore, the discharge pipe is divided into a first discharge pipe and a second discharge pipe. The first discharge pipe is fixedly connected to the rear side of the second separation pipe in an inclined manner, and the second discharge pipe is fixedly connected to the rear side of the third separation pipe in an inclined manner.
[0010] Furthermore, the first discharge pipe is connected to the middle of the second separation pipe, and a second screen and a second pusher are provided in the lower part of the second separation pipe. The second pusher pushes the water flow along the second separation pipe from the outside to the inside.
[0011] Furthermore, the second screen is adjacent to the first discharge pipe, and the second screen is inclined toward the first discharge pipe.
[0012] Furthermore, the second discharge pipe is connected to the middle of the third separation pipe, and a third screen and a third pusher are provided in the lower part of the third separation pipe. The third pusher pushes the water flow along the third separation pipe from the outside to the inside.
[0013] Furthermore, the third screen is adjacent to the second discharge pipe, and the third screen is inclined toward the second discharge pipe.
[0014] The beneficial effects of this utility model are as follows: the second and third separation pipes can separate manganese nodules and mud and sand twice under the action of gravity. The manganese nodules can be discharged and stored through the second and third separation pipes. Furthermore, the second and third separation pipes generate an upward low-speed water flow through the pusher, which can block the entry of mud and sand. The mud and sand can be discharged directly through the first separation pipe, which effectively improves the separation effect of manganese nodules and mud and sand, avoids the problem of clogging the recovery pump pipe and occupying extra storage space after recovering mud and sand and other attachments, and significantly improves the efficiency of manganese nodule collection.

[0021] This utility model discloses a gravity-type multi-stage mineral sand separation device. The following describes one embodiment of this utility model in detail with reference to the accompanying drawings.
[0022] like Figure 1 As shown, a gravity-type multi-stage mineral sand separation device includes a first separation component and a second separation component. The first separation component includes a first separation pipe 1, which has a conduit for manganese nodules and mud / sand flow. A funnel-shaped collection port 2 is fixedly connected to the front end of the first separation pipe 1. A first screen 7 and a first actuator 8 are arranged inside the rear part of the first separation pipe 1, and the first actuator 8 is located outside the first screen 7. The first actuator 8 propels water to flow from the inside to the outside along the first separation pipe 1.
[0023] Combination Figure 2 and Figure 3 As shown, the second separation assembly includes a second separation tube 3 and a third separation tube 4. Both the second separation tube 3 and the third separation tube 4 are inclined, and their top ends are fixedly connected to the bottom of the middle part of the first separation tube 1. Both the second separation tube 3 and the third separation tube 4 have pipes for manganese nodules and mud / sand flow, and the pipes of the second separation tube 3 and the third separation tube 4 are connected to the pipes of the first separation tube 1.
[0024] Combination Figure 4 and Figure 5 As shown, a first discharge pipe 5, oriented at an incline, is located on the rear side of the middle portion of the second separation pipe 3. The first discharge pipe 5 is fixedly connected to the second separation pipe 3. A second screen 9 and a second pusher 10 are located inside the lower part of the second separation pipe 3. The second pusher 10 is located outside the second screen 9 and pushes the water flow along the second separation pipe 3 from the outside to the inside. The second screen 9 is adjacent to the first discharge pipe 5 and is oriented at an incline towards the first discharge pipe 5. A second discharge pipe 6, oriented at an incline, is located on the rear side of the middle portion of the third separation pipe 4. The second discharge pipe 6 is fixedly connected to the third separation pipe 4. A third screen 11 and a third pusher 12 are located inside the lower part of the third separation pipe 4. The third pusher 12 is located outside the third screen 11 and pushes the water flow along the third separation pipe 4 from the outside to the inside. The third screen 11 is adjacent to the second discharge pipe 6 and is oriented at an incline towards the second discharge pipe 6.
[0025] Manganese nodules with silt and sand adhering to their surface enter the first separation pipe 1 through the funnel-shaped collection port 2. The first actuator 8, located inside the first separation pipe 1, propels the water flow from the inside out, thus carrying the manganese nodules and silt into the first separation pipe 1. As the manganese nodules and silt move along the first separation pipe 1, some manganese nodules, under the influence of gravity, enter the second separation pipe 3 through the connection between the second separation pipe 3 and the first separation pipe 1, undergoing initial separation. The remaining manganese nodules and silt continue to move along the first separation pipe 1. The second actuator 10 in the second separation pipe 3 propels the water flow from the outside inwards along the second separation pipe 3 and into the first separation pipe 1, preventing silt and sand from entering the second separation pipe 3. After entering the second separation pipe 3, the manganese nodules come into contact with the second screen 9 and enter the first discharge pipe 5 along the inclined second screen 9, finally being discharged through the first discharge pipe 5 for storage.
[0026] As the remaining manganese nodules and silt move along the first separation pipe 1, under the influence of gravity, the manganese nodules enter the third separation pipe 4 through the connection between the third separation pipe 4 and the first separation pipe 1, undergoing a second separation. The first screen 7 located in the first separation pipe 1 blocks the manganese nodules, allowing only silt to pass through and be discharged. The third actuator 12 located in the third separation pipe 4 drives the water flow from the outside to the inside of the third separation pipe 4 and into the first separation pipe 1. The water flow prevents silt and other adhering substances from entering the third separation pipe 4. After entering the third separation pipe 4, the manganese nodules come into contact with the third screen 11 and enter the second discharge pipe 6 along the inclined third screen 11, finally being discharged and stored through the second discharge pipe 6.
[0027] When manganese nodules become blocked in the second separation tube 3 and the third separation tube 4, the staff can adjust the power of the second actuator 10 and the third actuator 12 to adjust the flow rate in the second separation tube 3 and the third separation tube 4 to generate flow pulses. The flow pulses can then be used to apply a loosening impact force to the blocked manganese nodules, which can effectively solve the manganese nodule blockage problem.
[0028] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
