Description

Technical Field

[0001] This invention relates to the field of mining machinery technology, specifically to an energy-saving mineral processing equipment. Background Technology

[0002] Mineral processing is a crucial step in the processing and utilization of mineral resources. Centrifugal mineral processing equipment is widely used in the processing of both metallic and non-metallic minerals due to its high separation efficiency. Existing centrifugal mineral processing equipment typically includes an outer cylinder, a rotating drum, a drive assembly, and a feeding mechanism. An annular guide plate inside the outer cylinder constrains the rotation of the rotating drum. The drive assembly drives the rotating drum to rotate, and the ore enters the drum through the feed pipe and mixes with water. Under the action of centrifugal force, the concentrate and tailings are separated.

[0003] However, existing equipment still has many shortcomings in practical applications: First, the uniformity of slurry mixing is poor. Traditional equipment often supplies water directly through water inlets on the inner wall of the drum, resulting in a limited water flow distribution range, especially uneven water flow coverage along the height of the drum. This makes it difficult for the ore and water to mix quickly and thoroughly, leading to large fluctuations in slurry concentration and affecting the accuracy and efficiency of mineral processing. Second, cleaning the drum is inconvenient. After mineral processing, some concentrate tends to adhere to the inner wall of the drum due to adhesion. Existing equipment requires manual cleaning after shutdown, which not only increases the workload but also affects the efficiency of continuous operation.

[0004] Therefore, how to design an energy-saving mineral processing equipment that can improve the uniformity of slurry mixing and facilitate the cleaning of the rotary drum has become an urgent technical problem to be solved in the field of mining machinery. Summary of the Invention

[0034] Example 1

[0035] Please combine Figures 1 to 6As shown, this invention discloses an energy-saving mineral processing equipment, which mainly consists of an outer cylinder 1, a mineral processing rotary drum 3, a drive assembly, a feeding mechanism, and an auxiliary water supply mechanism. The outer cylinder 1 serves as the main frame of the equipment and is bolted to a frame 2. The frame 2 is made of high-strength steel and has anti-slip pads at the bottom to ensure stability during operation. An annular guide plate 27 is welded and fixed inside the outer cylinder 1. The inner diameter of the annular guide plate 27 matches the outer diameter of the mineral processing rotary drum 3. The outer wall of the mineral processing rotary drum 3 is rotatably connected to the inner ring of the annular guide plate 27 via ball bearings, achieving stable rotation of the mineral processing rotary drum 3 under the constraint of the annular guide plate 27. A first outlet is provided on the side wall of the outer cylinder 1, above the annular guide plate 27. This first outlet has a rectangular structure with guide plates welded to its edges to guide tailings discharge.

[0036] A water supply pipe 5, made of stainless steel, is rotatably mounted at the bottom center of the outer cylinder 1 via a sealed bearing. A water collection chamber 4 is coaxially formed inside the mineral processing rotary drum 3. The top end of the water supply pipe 5 is fixedly connected to the bottom center of the mineral processing rotary drum 3 via a flange, and the interior of the water supply pipe 5 is connected to the water collection chamber 4 to ensure the sealing of the water supply channel. A drive assembly is fixedly mounted on the outer wall of the outer cylinder 1 via a motor mount. This drive assembly drives the water supply pipe 5 to rotate, thereby causing the mineral processing rotary drum 3 to rotate synchronously. The drive assembly includes a first motor 6 and a transmission belt 7. The first motor 6 is a servo motor with a drive pulley mounted on its output end. A driven pulley is mounted on the lower outer wall of the water supply pipe 5. The transmission belt 7 is a rubber synchronous belt, with one end fitted onto the drive pulley and the other end fitted onto the driven pulley, achieving power transmission through belt drive.

[0037] A feed pipe 8 is welded and fixed to the top side wall of the outer cylinder 1, and its bottom end extends 5-8 cm above the inner bottom surface of the mineral processing rotary cylinder 3, maintaining a uniform interval between it and the inner bottom surface of the mineral processing rotary cylinder 3 to avoid ore accumulation and blockage. A discharge port 26 is welded to the bottom edge of the mineral processing rotary cylinder 3.

[0038] A water storage pipe 12 is rotatably mounted on the outer surface of the feed pipe 8 via a bearing. The water storage pipe 12 has an annular structure and is coaxially arranged with the feed pipe 8. The water storage pipe 12 has a water storage cavity inside. Multiple channels 15 are evenly distributed along the circumference on the outer surface of the water storage pipe 12. Each channel 15 has a circular hole, and a second collecting pipe 11 is rotatably mounted at each channel 15 via a rotary joint. A first collecting pipe 9 is rotatably mounted on the lower middle part of the outer surface of the mineral processing drum 3 via a rotary joint. The first collecting pipe 9 also has an annular structure. Multiple through holes with a diameter of 5-8 mm are evenly distributed along the circumference on the side wall of the mineral processing drum 3. The interior of the first collecting pipe 9 communicates with the water collection cavity 4 through these through holes, and the outer wall of the first collecting pipe 9 is fixedly connected to the inner surface of the outer cylinder 1 via a bracket to ensure that the first collecting pipe 9 remains stationary. The first collecting pipe 9 and the second collecting pipe 11 are fixedly connected by multiple first connecting pipes 10. The two ends of the first connecting pipes 10 are connected to the first collecting pipe 9 and the second collecting pipe 11 respectively via clamps.

[0039] A rotating assembly is installed on the top of the outer cylinder 1. This rotating assembly enables the water storage pipe 12 to rotate in the opposite direction to the rotation of the mineral processing drum 3. The rotating assembly includes a gear ring 16, a gear 17, and a second motor 18. The second motor 18 is fixedly installed on the top surface of the outer cylinder 1 through a motor base. The output end of the second motor 18 is fixedly installed with the gear 17 through a key connection. The gear ring 16 is welded and fixed at the top edge of the water storage pipe 12. The gear ring 16 and the gear 17 are meshed together, and the reverse rotation of the water storage pipe 12 is achieved through gear transmission.

[0040] Multiple straight pipes 13 are arranged circumferentially on the outer side of the water storage pipe 12. The straight pipes 13 are made of stainless steel, and one end of each straight pipe 13 is connected to the inside of the water storage pipe 12 through a flexible hose 14. The flexible hose 14 is made of corrosion-resistant rubber. The multiple straight pipes 13 are distributed in a spiral shape at equal intervals along the height direction of the water storage pipe 12, and the straight pipes 13 at higher positions are longer, with a length difference of 5-8 cm, to ensure that the water flow can cover different height areas inside the mineral processing drum 3.

[0041] A spiral rod 22 is coaxially mounted on the outer side of the water storage pipe 12. A ring rod 24 is welded to the top of the spiral rod 22 via multiple first connecting rods 23. A movable ring 19 is welded to the upper surface of the ring rod 24 via multiple second connecting rods 25. The second connecting rods 25 are vertically positioned, and their tops penetrate the top of the outer cylinder 1 and are slidably connected to it, guiding the movable ring 19 up and down. The upper surface of the movable ring 19 is inclined at an angle of 15-20°. An elastic element, a spring 21, is fixedly installed between the movable ring 19 and the inner bottom surface of the outer cylinder 1. The springs 21 are evenly distributed along the circumference of the movable ring 19, with their tops welded to the movable ring 19 and their bottoms welded to the inner bottom surface of the outer cylinder 1. A pressure head 20 is rotatably mounted on the outer surface of the water storage pipe 12 via a bracket. The pressure head 20 is a roller structure, and its outer surface is tightly fitted with the upper surface of the movable ring 19 to ensure transmission stability between them.

[0042] First, the first motor 6 is started. The first motor 6 drives the water supply pipe 5 to rotate via the transmission belt 7, which in turn drives the mineral processing drum 3 to rotate. At the same time, high-pressure water is introduced into the water supply pipe 5. The water is transported to the water collection chamber 4 through the water supply pipe 5. Multiple water supply holes with a diameter of 3-5 mm are evenly opened along the circumference on the inner side wall of the mineral processing drum 3. The water in the water collection chamber 4 enters the interior of the mineral processing drum 3 evenly through the water supply holes.

[0043] The ore is continuously fed to the bottom of the concentrator drum 3 through the feed pipe 8. The ore mixes with the incoming water to form a slurry. Under the centrifugal force generated by the rotation of the concentrator drum 3, the tailings with lower density move towards the top of the concentrator drum 3 and eventually overflow from the top of the concentrator drum 3, falling onto the annular guide plate 27 and then being discharged outside the equipment through the first outlet. The concentrate with higher density moves towards the bottom of the concentrator drum 3 and is discharged through the discharge outlet 26.

[0044] During the mineral processing, some of the water entering the water collection chamber 4 enters the first collecting pipe 9 through the through hole, and then is transported to the second collecting pipe 11 through multiple first connecting pipes 10. Finally, it is sprayed into the interior of the mineral processing drum 3 through multiple straight pipes 13. At the same time, the second motor 18 is started. The second motor 18 drives the water storage pipe 12 to rotate through the meshing transmission of the gear 17 and the gear ring 16, and the rotation direction of the water storage pipe 12 is opposite to that of the mineral processing drum 3. The pressure head 20 rotates synchronously with the water storage pipe 12. Since the upper surface of the movable ring 19 is inclined, the pressure head 20 contacts different height positions of the upper surface of the movable ring 19 during the rotation, thereby periodically pressing down the movable ring 19 to make it move downward. Under the elastic force of the spring 21, the movable ring 19 will return to its original position upward. This cycle is repeated to realize the reciprocating lifting and lowering of the screw rod 22 in the height direction.

[0045] When the water storage pipe 12 rotates, under the action of centrifugal force, the straight pipe 13 can deflect outward to a horizontal state; when the screw rod 22 moves downward, it will press down on multiple straight pipes 13, causing them to deflect downward, thus realizing the vertical oscillation of the straight pipes 13. This oscillation allows the water to be more evenly dispersed inside the mineral processing drum 3, accelerating the mixing of water and ore, improving the uniformity of slurry concentration, and thus promoting a 15%-20% increase in mineral processing efficiency.

[0046] Furthermore, after mineral processing, some concentrate adheres to the inner surface of the mineral processing drum 3 due to adhesion, making it difficult to detach naturally. At this time, water continues to be supplied to the water supply pipe 5, while the water storage pipe 12 continues to rotate. The straight pipe 13 sprays high-pressure water onto the inner surface of the mineral processing drum 3. After the water impacts the inner surface of the mineral processing drum 3, the concentrate is detached from the inner surface by the impact force of the water and then discharged from the outlet 26 with the water flow, thus achieving automatic cleaning of the inner wall of the mineral processing drum 3.

[0047] Example 2

[0048] The bottom of the outer cylinder 1 is inclined at an angle of 20-25° to facilitate the collection of concentrate towards the outlet. A second outlet is located at the lowest point of the bottom of the outer cylinder 1, and a gate valve is installed at the second outlet to control the amount of concentrate discharged. A concentrate chamber is formed between the inner bottom surface of the outer cylinder 1 and the lower surface of the annular guide plate 27. An annular pipe 40 is fixedly installed on the top of the concentrate chamber by a bracket, and the annular pipe 40 is coaxially arranged with the outer cylinder 1. Multiple water outlets 43, numbering 8-12, are evenly fixedly installed on the lower surface of the annular pipe 40 along the circumferential direction. Their outlet ends face the inner wall of the outer cylinder 1 at a 45° angle to the inner wall, ensuring that the water flow can be sprayed onto the inner wall surface of the concentrate chamber.

[0049] A filter plate 44 is welded and fixed to the inclined surface at the bottom of the outer cylinder 1. The filter plate 44 is made of stainless steel filter screen with a mesh diameter of 1-2mm, used to filter concentrate particles in the water. A collection tank 28 is fixedly installed on the lower surface of the outer cylinder 1, directly below the filter plate 44, via a bracket, for collecting the filtered water. A water suction box 29 and a collection pipe 36, both made of stainless steel, are fixedly installed on the outer wall at the bottom of the outer cylinder 1 via a bracket.

[0050] A first connecting pipe 30 is welded to both ends of the water suction box 29 along its length. The other ends of both first connecting pipes 30 are welded to the bottom outlet of the collection tank 28. A first one-way valve 31 is installed on each first connecting pipe 30, with the first one-way valve 31 guiding from the collection tank 28 to the water suction box 29 to prevent backflow. Second connecting pipes 37 are also welded to both ends of the water suction box 29 along its length. One end of each second connecting pipe 37 is welded to both ends of the concentrator 36 along its length. A second one-way valve 38 is installed on each second connecting pipe 37, with the second one-way valve 38 guiding from the water suction box 29 to the concentrator 36. A third connecting pipe 39 is welded to the middle of the concentrator 36, with the other end of the third connecting pipe 39 welded to the side wall of the annular pipe 40, enabling internal communication between the concentrator 36 and the annular pipe 40.

[0051] A movable plate 32 is slidably installed inside the water absorption box 29. A sealing strip is installed on the outer wall of the movable plate 32 to ensure a tight seal with the inner wall of the water absorption box 29. A reciprocating motion assembly is installed on the outer side of the water absorption box 29, causing the movable plate 32 to reciprocate axially within the water absorption box 29. The reciprocating motion assembly includes a threaded rod 33 and a third motor 35. The third motor 35 is a stepper motor, fixedly mounted on the outer wall of the water absorption box 29 via a motor mount. The threaded rod 33 is rotatably mounted inside the water absorption box 29 via bearings, coaxially arranged with the water absorption box 29. One end of the threaded rod 33 passes through the interior of the movable plate 32 and is threadedly connected to the movable plate 32. The output end of the third motor 35 is fixedly connected to one end of the threaded rod 33 via a coupling. A sliding rod 34 is also fixedly installed inside the water absorption box 29. The sliding rod 34 is parallel to the threaded rod 33, and one end of it passes through the interior of the movable plate 32 and is slidably connected to the movable plate 32, serving as a guide to prevent the movable plate 32 from rotating.

[0052] A semi-arc tube 41 is welded and fixed to the top edge of the inner bottom surface of the outer cylinder 1. The semi-arc tube 41 fits against the inner bottom surface of the outer cylinder 1, and its two ends are closed. The semi-arc tube 41 is connected to the interior of the annular tube 40 through multiple fourth connecting pipes 42. The fourth connecting pipes 42 are evenly distributed along the length of the semi-arc tube 41. Multiple water outlet holes with a diameter of 2-3 mm are evenly opened on the lower surface of the semi-arc tube 41, facing the bottom of the concentrate chamber.

[0053] In the mineral processing of Example 1, the discharge outlet 26 rotates synchronously with the mineral processing drum 3, centrifugally ejecting the concentrate. The ejected concentrate disperses in the concentrate cavity between the annular guide plate 27 and the inner bottom surface of the outer cylinder 1. Some concentrate adheres to the inner wall of the concentrate cavity due to moisture. The mixture of concentrate and water moves towards the second outlet along the inclined bottom end of the outer cylinder 1 under the action of gravity. The concentrate is discharged from the second outlet, while some water is filtered by the filter plate 44 and enters the collection tank 28 for storage, achieving preliminary water recovery.

[0054] The third motor 35 is started, which drives the threaded rod 33 to rotate alternately in both forward and reverse directions. Since the threaded rod 33 is threadedly connected to the movable plate 32, and the slide rod 34 guides the movable plate 32, the movable plate 32 reciprocates linearly in the axial direction of the water suction box 29. When the movable plate 32 moves to one side, the volume of the cavity on one side of the water suction box 29 increases, creating a negative pressure, which draws water from the collection tank 28 through the first connecting pipe 30 and the first one-way valve 31; at the same time, the volume of the cavity on the other side of the movable plate 32 decreases, and the internal water pressure increases, forcing the water through the second connecting pipe 37 and the second one-way valve 38 into the collection pipe 36.

[0055] Water in the central pipe 36 is transported to the annular pipe 40 via the third connecting pipe 39. Part of the water is sprayed onto the inner wall of the concentrate chamber through the outlet 43 on the annular pipe 40, washing away the concentrate adhering to the wall. The other part of the water is transported to the semi-arc pipe 41 via the fourth connecting pipe 42, and then sprayed onto the top edge of the inner bottom surface of the outer cylinder 1 through the outlet holes on the semi-arc pipe 41, forming a water flow barrier to prevent concentrate accumulation at the edge. In this way, the concentrate can move smoothly to the bottom of the concentrate chamber, allowing it to be discharged smoothly from the second outlet without clogging. Simultaneously, water resources are recycled, achieving a water saving rate of 30%-40%.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention.
