[0002] Magnesia ore is an important mineral raw material for extracting metallic magnesium. It mainly includes types such as magnesite and dolomite, and is characterized by its lightweight and corrosion resistance, making it widely used in aerospace, automobile manufacturing, and other fields. The mining process of magnesium ore requires washing and screening, which necessitates the use of magnesium ore washing and screening equipment. However, existing magnesium ore washing and beneficiation equipment uses a conveyor belt to feed the ore onto an inclined filter screen, which vibrates to slowly move the ore for screening. Water spray nozzles are installed above the ore to wash it. However, this method has certain drawbacks. In order to ensure that the ore has a certain contact time with the water flow, the vibration amplitude of the filter screen is small. For some large ores, the small vibration amplitude is not enough to turn the ore over, resulting in insufficient cleaning of the ore. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] This embodiment:

[0017] Please see Figure 1-10 In this embodiment: a magnesium ore washing and beneficiation device includes: a washing cylinder 1, a washing and beneficiation structure, a shell 2, and a water supply structure.

[0018] In this embodiment, the washing and screening structure is located inside the washing cylinder 1 and is used to wash and screen the ore.

[0019] In this embodiment, by operating the washing and screening structure, the ore will move in a spiral. During the movement, the ore will be turned over by its own gravity and external thrust. In this process, the ore will be screened and will come into full contact with clean water, so that even large ore can be cleaned, thus achieving thorough cleaning of the ore.

[0020] The outer shell 2 is fixedly connected to one end of the washing cylinder 1; the water supply structure is located inside the outer shell 2 and connected to the washing and screening structure, and is used to supply water to the washing and screening structure.

[0021] In this embodiment, the water supply structure is used to provide clean water to the washing and beneficiation structure, thereby cleaning the ore.

[0022] like Figure 5 and Figure 6 As shown, the washing and screening structure includes: a screening cylinder 3, a rotating shaft 4, multiple sets of spiral fan blades 5, a bevel gear set 6, and a first motor 7.

[0023] Specifically, the screening cylinder 3 is coaxially disposed inside the washing cylinder 1 and is fixedly connected to the washing cylinder 1; multiple sets of through holes are evenly opened on the surface of the screening cylinder 3 along the axis, so that the interior of the screening cylinder 3 can be connected to the interior of the washing cylinder 1 through the through holes.

[0024] In this embodiment, the through hole is used to screen the ore; the space between the washing cylinder 1 and the screening cylinder 3 is used to store the screened ore.

[0025] The rotating shaft 4 is coaxially disposed inside the screening cylinder 3 and is rotatably connected to the screening cylinder 3; a space is opened inside the rotating shaft 4 along the axial position, and the space is connected to the inside of the screening cylinder 3 through a through hole opened on the surface of the rotating shaft 4.

[0026] In this embodiment, clean water can enter the screening cylinder 3 through the space inside the rotating shaft 4 and the through holes on its surface, and clean the ore.

[0027] Multiple sets of spiral fan blades 5 are evenly distributed on the outside of the rotating shaft 4 and are fixedly connected to the rotating shaft 4.

[0028] In this embodiment, the number of multiple sets of spiral fan blades 5 is greater than 2 sets, which can drive the ore to move. By controlling the rotation speed of the spiral fan blades 5, the contact time between the ore and the water can be controlled.

[0029] The bevel gear set 6 consists of a first bevel gear and a second bevel gear. The axis of the first bevel gear is fixedly connected to the end of the rotating shaft 4 near the outer casing 2. The edge of the first bevel gear meshes with the edge of the second bevel gear. The output end of the first motor 7 is fixedly connected to the axis of the second bevel gear.

[0030] In this embodiment, the first motor 7 is a common device on the market, and its model can be selected according to actual needs as long as it meets the working conditions; the gear ratio of the first bevel gear and the second bevel gear is 3 to 1, that is, the second bevel gear can drive the first bevel gear to rotate one revolution after rotating three revolutions.

[0031] During cleaning and screening, the ore is fed into the screening cylinder 3, and the external power supply of the first motor 7 is connected. The first motor 7 is started, and its output end drives the rotating shaft 4 to rotate through the bevel gear set 6. The rotating shaft 4 simultaneously drives multiple sets of spiral fan blades 5 to rotate. The spiral fan blades 5 push the ore to move, and small stones in the ore will move into the washing cylinder 1 through the through holes on the surface of the screening cylinder 3. During this process, the ore will be turned over under its own gravity and external thrust. At the same time, clean water will be discharged from the through holes on the surface of the rotating shaft 4 and make full contact with the ore, so that even larger ore can be cleaned, achieving thorough cleaning of the ore.

[0032] like Figure 3 and Figure 4As shown, an inlet is provided at the top of the screening cylinder 3 near the outer shell 2; an outlet is provided at the bottom of the screening cylinder 3 away from the outer shell 2; the inlet and outlet are rectangular in shape.

[0033] like Figure 1 and Figure 2 As shown, the washing and screening structure also includes: inlet pipe 11 and outlet pipe 12.

[0034] The inlet pipe 11 passes through the washing cylinder 1 and is connected to the inlet, and is used to allow the ore to enter the screening cylinder 3.

[0035] In this embodiment, the ore can be sent to the screening cylinder 3 through the inlet pipe 11 and the inlet.

[0036] The outlet pipe 12 passes through the washing cylinder 1 and is connected to the outlet, and is used to send the washed ore out of the screening cylinder 3.

[0037] In this embodiment, the cleaned and screened ore can be sent out of the screening cylinder 3 through the outlet pipe 12 and the outlet.

[0038] The magnesium ore washing and beneficiation device also includes: a cleaning structure; the cleaning structure is connected to the screening cylinder 3 and is used to clean the screened ore.

[0039] like Figure 4 and Figure 5 As shown, the cleaning structure includes a cleaning ring 8 and an electric push rod 9.

[0040] The cleaning ring 8 is located between the screening cylinder 3 and the washing cylinder 1, and is situated on the side of the inlet pipe 11 near the outer casing 2.

[0041] In this embodiment, when the cleaning ring 8 moves, it pushes the ore located between the screening cylinder 3 and the washing cylinder 1 to the outlet.

[0042] The output end of the electric push rod 9 is fixedly connected to the cleaning ring 8, so that the cleaning ring 8 can move along the axis of the screening cylinder 3.

[0043] In this embodiment, the output end of the electric push rod 9 can push the cleaning ring 8 to move; the model of the electric push rod 9 is selected according to actual needs, as long as it meets the working conditions.

[0044] When cleaning is required, the external power supply of the electric push rod 9 is turned on, so that the output end of the electric push rod 9 pushes the cleaning ring 8 to move. The cleaning ring 8 will push the ore between the screening cylinder 3 and the washing cylinder 1 to the outlet and discharge it from the device.

[0045] During cleaning, the inlet pipe 11 and outlet pipe 12 can obstruct the movement of the cleaning ring 8, resulting in incomplete cleaning.

[0046] To address the aforementioned issues, this embodiment proposes an implementation method in which the magnesium ore washing and beneficiation device further includes a movable structure. The movable structure is disposed within the outer casing 2 and is connected to the inlet pipe 11 and the outlet pipe 12, respectively, for moving the inlet pipe 11 and the outlet pipe 12.

[0047] like Figure 9 and Figure 10 As shown, the moving structure includes: a moving part 18, a second connecting rod 17, a threaded rod 19, a second motor 20, two sets of connecting parts 16, a first connecting rod 13, a limiting part 14, and a rotating part 15.

[0048] Specifically, the second connecting rod 17 passes through the outer shell 2 and is slidably connected to the outer shell 2; the two ends of the second connecting rod 17 are fixedly connected to the moving part 18 and the inlet pipe 11, respectively.

[0049] In this embodiment, when the movable component 18 moves, it will drive the second connecting rod 17 to move; the second connecting rod 17 will simultaneously drive the inlet pipe 11 to move.

[0050] The threaded rod 19 passes through the movable part 18 and is threadedly connected to the movable part 18; the output end of the second motor 20 is fixedly connected to one end of the threaded rod 19.

[0051] In this embodiment, when the threaded rod 19 rotates, it causes the moving part 18 to move vertically; the second motor 20 is a common device on the market, and its model can be selected according to actual needs as long as it meets the working conditions.

[0052] Two sets of connectors 16 are symmetrically arranged on both sides of the second connecting rod 17; the surface of each set of the second connecting rod 17 is provided with the first cylindrical pin.

[0053] In this embodiment, the second connecting rod 17 simultaneously drives the two sets of connecting parts 16 to move vertically.

[0054] One end of the first connecting rod 13 is fixedly connected to the outlet pipe 12, and the other end is provided with a second cylindrical pin.

[0055] In this embodiment, the moving direction of the first connecting rod 13 is opposite to the moving direction of the second connecting rod 17.

[0056] The limiting member 14 is sleeved on the outside of the first connecting rod 13 and is slidably connected to the first connecting rod 13; the surface of the limiting member 14 is fixedly connected to the outer shell 2.

[0057] In this embodiment, the limiting member 14 can restrict the first connecting rod 13 to move only vertically.

[0058] The rotating component 15 has a first sliding groove and a second sliding groove at both ends; the rotating component 15 is slidably connected to the first cylindrical pin through the first sliding groove; the rotating component 15 is slidably connected to the second cylindrical pin through the second sliding groove.

[0059] In this embodiment, when the connecting member 16 moves vertically, the rotating member 15 rotates along the central pin shaft through the sliding between the first cylindrical pin and the first groove; while when the rotating member 15 rotates, the second connecting rod 17 moves vertically in the opposite direction to the first connecting rod 13 through the sliding between the second groove and the second cylindrical pin.

[0060] When it is necessary to move the inlet pipe 11 and the outlet pipe 12, the external power supply of the second motor 20 is turned on, and the second motor 20 is started. The output end of the second motor 20 drives the threaded rod 19 to rotate. The threaded rod 19 causes the moving part 18 to move vertically upward. The moving part 18 drives the second connecting rod 17 to move. The second connecting rod 17 simultaneously drives the two sets of connecting parts 16 and the inlet pipe 11 to move upward. The connecting part 16 will slide between the first cylindrical pin and the first slide groove, causing the rotating part 15 to rotate along the central pin shaft. When the rotating part 15 rotates, it will slide between the second slide groove and the second cylindrical pin, causing the second connecting rod 17 to move vertically in the opposite direction to the first connecting rod 13. The first connecting rod 13 simultaneously drives the outlet pipe 12 to move vertically downward. This causes the inlet pipe 11 and the outlet pipe 12 to move away from the screening cylinder 3, providing space for the movement of the cleaning ring 8.

[0061] like Figure 7 and Figure 8 As shown, the water supply structure includes: a water tank 21, a sealed bearing 24, a water pipe 22, and a water pump 23.

[0062] The interior of the connecting water tank 21 is connected to the end of the rotating shaft 4 near the bevel gear set 6; the sealed bearing 24 is disposed between the connecting water tank 21 and the rotating shaft 4, so that the rotating shaft 4 can rotate relative to the connecting water tank 21.

[0063] In this embodiment, the sealed bearing 24 allows the rotating shaft 4 to rotate along the contact surface with the connected water tank 21, while the sealed bearing 24 prevents water leakage.

[0064] One end of the water pipe 22 is connected to the water tank 21; the output end of the water pump 23 is connected to the other end of the water pipe 22; and the input end of the water pump 23 is connected to the outside.

[0065] In this embodiment, the water pump 23 is a common device on the market, and its model can be selected according to actual needs as long as it meets the working conditions.

[0066] When cleaning is required, connect the external power supply to the water pump 23 and start the water pump 23. The water pump 23 will draw clean water from the outside into the water pump 23 and send it to the water tank 21 through the connecting water pipe 22. The water is then sprayed from the rotating shaft 4 into the screening cylinder 3 to clean the ore.

[0067] like Figure 2 As shown, the magnesium ore washing and beneficiation device also includes: an arc-shaped trough 10; the arc-shaped trough 10 is located at the end of the washing cylinder 1 away from the outer shell 2, and is used to discharge wastewater.

[0068] In this embodiment, the wastewater that has been cleaned can be discharged through the arc-shaped groove 10.

[0069] Working principle: When using the magnesium ore washing and beneficiation device, first connect the external power supply of the water pump 23 and start the water pump 23. The water pump 23 will draw clean water from the outside into the water pump 23 and send it to the water tank 21 through the connecting water pipe 22. Then, it will be sprayed from the rotating shaft 4 into the screening cylinder 3 to clean the ore.

[0070] During cleaning and screening, the ore is fed into the screening cylinder 3, and the external power supply of the first motor 7 is connected. The first motor 7 is started, and its output end drives the rotating shaft 4 to rotate through the bevel gear set 6. The rotating shaft 4 simultaneously drives multiple sets of spiral fan blades 5 to rotate. The spiral fan blades 5 push the ore to move, and small stones in the ore will move into the washing cylinder 1 through the through holes on the surface of the screening cylinder 3. During this process, the ore will be turned over under its own gravity and external thrust. At the same time, clean water will be discharged from the through holes on the surface of the rotating shaft 4 and make full contact with the ore, so that even larger ore can be cleaned, achieving thorough cleaning of the ore.

[0071] When cleaning is required, the external power supply of the electric push rod 9 is turned on, so that the output end of the electric push rod 9 pushes the cleaning ring 8 to move. The cleaning ring 8 will push the ore between the screening cylinder 3 and the washing cylinder 1 to the outlet and discharge it from the device.

[0072] Before cleaning, the external power supply of the second motor 20 is connected and the second motor 20 is started. The output end of the second motor 20 drives the threaded rod 19 to rotate. The threaded rod 19 causes the moving part 18 to move vertically upward. The moving part 18 drives the second connecting rod 17 to move. The second connecting rod 17 simultaneously drives the two sets of connecting parts 16 and the inlet pipe 11 to move upward. The connecting part 16 slides between the first cylindrical pin and the first slide groove, causing the rotating part 15 to rotate along the central pin. When the rotating part 15 rotates, it slides between the second slide groove and the second cylindrical pin, causing the second connecting rod 17 to move vertically in the opposite direction to the first connecting rod 13. The first connecting rod 13 simultaneously drives the outlet pipe 12 to move vertically downward. This causes the inlet pipe 11 and the outlet pipe 12 to move away from the screening cylinder 3, providing space for the movement of the cleaning ring 8, thus completing the use of this device.
