Description

Technical Field

[0001] The present invention relates to the technical field of ore washing equipment, and more particularly to an ore washing equipment for ore dressing. Background Art

[0002] Minerals generally refer to all natural minerals or rock resources buried underground (or distributed on the surface of the earth, or weathered from rocks, or deposited from rocks) that can be utilized by humans. Minerals can be classified into categories such as metals, non-metals, combustible organics, etc., and are non-renewable resources. Before ore dressing and processing, it is necessary to clean the ore raw materials to remove various impurities attached to the ore surface, including dust, clay, and other impurities. Removing the impurities on the ore surface facilitates subsequent further processing such as ore dressing of the ore. Currently, the commonly used ore washing equipment in industry includes a drum-type ore washer. The drum-type ore washer is suitable for the cleaning process of ores with a larger diameter, mainly by placing the ore in a rotating drum and cooperating with water flow to wash the ore.

[0003] For example, Chinese Patent Publication No. CN119034921A discloses an ore washing machine for ore dressing, which includes a base and a washing drum. The washing drum is located above the base. The base is provided with a driving member for driving the washing drum to rotate. The washing drum is provided with a spiral push plate for pushing the ore to move. The washing drum is also provided with a water pipe, which is communicated with an external water supply system. The lower end of the water pipe is provided with a plurality of arc-shaped plates, and the arc-shaped plates are provided with drainage holes communicated with the water pipe. A blocking pipe is coaxially rotated outside the water pipe, and the base is provided with a power member for driving the blocking pipe to rotate. A connecting plate is fixedly connected between adjacent blocking pipes. The connecting plate is slidably connected with a cleaning plate in a direction close to or away from the axis of the water pipe. The connecting plate is provided with an elastic member for limiting the cleaning plate. The cleaning plate is provided with a cleaning hole for cleaning the blocking pipe.

[0004] In the process of washing the ore in the above application, although the accumulation above the water pipe can be cleaned, due to the restriction and interception of the movement amplitude of the ore in the washing drum by the blocking plate and the intercepting plate, the movement degree of the ore in the washing drum is limited greatly, and the ore is prone to generate more accumulation, which affects the uniformity and comprehensiveness of the contact and cleaning between the ore surface and the washing water. It is difficult for the washing water to completely penetrate into more gaps of the ore, resulting in more cleaning dead corners remaining on the ore surface, affecting the overall ore washing effect. At the same time, only by a single washing water flow to clean and remove impurities on the ore surface, it is difficult to clean the impurities with a larger adhesion degree, and the overall cleaning effect is not good enough, which can be further improved.

[0005] Therefore, it is necessary to provide an ore washing equipment for ore dressing to solve the above technical problems. Summary of the Invention

[0008] As a further solution of the present invention, the assisting and moving assembly includes an inner tube inserted at the center of the interior of the washing cylinder and capable of rotating, one end of the inner tube is communicated with an air inlet pipe, the end of the inner tube is rotatably connected with the air inlet pipe through a bearing, and a plurality of equally spaced adjusting plates are fixed on the outer side wall of the inner tube.

[0009] As a further solution of the present invention, an inner cavity communicated with the interior of the inner tube is opened in the adjusting plate, and air blowing holes communicated with the inner cavity are opened on the side surface of the adjusting plate.

[0010] As a further solution of the present invention, a plurality of the air blowing holes are provided, and the plurality of air blowing holes are equally spaced.

[0011] As a further solution of the present invention, convex plates are fixed on the side surface of the adjusting plate, a plurality of the convex plates are provided, and the plurality of convex plates are distributed in a staggered manner with the air blowing holes.

[0012] As a further solution of the present invention, a differential adjusting assembly for driving the assisting and moving assembly to rotate at a differential speed relative to the washing cylinder is arranged at one end of the washing cylinder. The differential adjusting assembly includes a shaft rod rotatably connected to the side wall of the support plate, a first toothed ring is fixed at one end of the washing cylinder, a first gear meshed with the first toothed ring is fixed on the shaft rod, pulley wheels are fixed at the ends of the inner tube and the shaft rod respectively, and a belt is connected between the two pulley wheels.

[0013] As a further solution of the present invention, the driving and rotating assembly includes a second toothed ring fixed on the outer side wall of the washing cylinder, a driving motor is arranged at the bottom of the washing cylinder, and a second gear meshed with the second toothed ring is fixed on the output end of the driving motor.

[0014] As a further solution of the present invention, a plurality of the air blowing holes are all inclined.

[0015] As a further solution of the present invention, a bottom plate is commonly fixed to the bottom ends of the two bracket plates, a first support plate is fixed on the top surface of the bottom plate, one end of the built-in tube is rotatably connected to the first support plate, a second support plate is fixed on the outer wall of the bracket plate, and one end of the water pipe is rotatably connected to the second support plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The ore inside the washing tube is continuously turned over by the motion-increasing component, which improves the uniformity of ore distribution, reduces ore accumulation, effectively increases the degree of movement of ore inside the washing tube, and ensures that the ore always maintains a dynamic state during the washing process. This not only helps the dirt and impurities on the ore surface to gradually fall off, but also significantly improves the comprehensiveness of the ore surface exposure, so that the washing water can evenly contact more positions on the ore surface, improves the uniformity and comprehensiveness of the contact between the washing water and the ore, and thus effectively improves the overall washing effect;

[0018] 2. The booster component evenly blows air to the surface of the ore while flipping the ore, and the airflow is used to clean the stubborn impurities adhering to the surface of the ore. The combination of airflow blowing and flipping can assist in cleaning the surface of the ore, greatly improving the efficiency of removing impurities on the surface of the ore, especially for impurities with high adhesion, which further improves the quality of ore washing and improves the overall washing effect;

[0019] 3. The airflow blown out by the booster assembly blows away the excess water on the ore surface before conveying and discharging it, which helps to speed up the subsequent drying of the ore surface. The airflow blown out by the booster assembly blows away and cleans the ore accumulated on the water pipe, avoiding the situation where the ore accumulates and stays on the water pipe, thus eliminating the need for manual cleaning of the accumulation on the water pipe.

[0020] 4. The differential adjustment component is set to make the amplification component rotate differentially relative to the ore washing cylinder. The design of differential rotation increases the complexity of the movement trajectory of the ore inside the ore washing cylinder, so that the ore can be moved in multiple directions during the cleaning process, and the ore can be more fully in contact with the cleaning water, ensuring that the cleaning water can penetrate into more tiny gaps in the ore, further improving the overall cleaning effect and efficiency.

Detailed implementation manners

[0035] The present invention will be further described below in conjunction with embodiments.

[0036] Please refer to Figures 1-11, the present invention provides an ore washing equipment for ore dressing, which includes two support plates 5. A washing cylinder 4 is rotatably connected between the two support plates 5. A spiral pushing plate 11 is fixed on the inner side wall of the washing cylinder 4. An actuating assembly 3 for driving the washing cylinder 4 to rotate is arranged outside the washing cylinder 4. A water pipe 9 located at the top of the washing cylinder 4 is inserted into the interior of the washing cylinder 4. A plurality of water spraying nozzles 10 are opened at the bottom end of the water pipe 9. An actuating assembly 1 for stirring the ore and assisting in cleaning the surface of the ore is arranged inside the washing cylinder 4. A differential adjusting assembly 2 for driving the actuating assembly 1 to rotate at a differential speed relative to the washing cylinder 4 is arranged at one end of the washing cylinder 4. When in use, the ore to be cleaned is fed into the interior of the washing cylinder 4 through the open end of the washing cylinder 4. The driving assembly 3 drives the washing cylinder 4 to rotate, so that the spiral pushing plate 11 inside the rotating washing cylinder 4 continuously conveys the ore forward. The water pipe 9 is externally connected to a water pump, and water flow with a certain hydraulic pressure is conveyed into the water pipe 9 and sprayed out through the plurality of water spraying nozzles 10 onto the ore at the bottom of the washing cylinder 4, thereby washing the ore. During this process, the actuating assembly 1 continuously flips the ore inside the washing cylinder 4, improves the even distribution of the ore, reduces the accumulation of the ore, effectively increases the movement degree of the ore inside the washing cylinder 4, ensures that the ore always remains in a dynamic state during the cleaning process, not only helps the soil and impurities on the surface of the ore to gradually fall off, but also significantly improves the comprehensiveness of the exposure of the ore surface, enables the cleaning water to uniformly contact more positions on the surface of the ore, improves the uniformity and comprehensiveness of the contact between the cleaning water and the ore, and thus effectively improves the overall washing effect. Further, while flipping the ore, the actuating assembly 1 uniformly blows out air flow onto the surface of the ore, and the stubborn impurities adhered to the surface of the ore are specifically cleaned through the air flow, realizing the auxiliary cleaning of the surface of the ore. Through the combination of the air flow blowing and flipping actions, the falling-off efficiency of the impurities on the surface of the ore is greatly improved, especially for the impurities with higher adhesiveness, which has a significant cleaning effect, further improves the ore washing quality and the overall washing effect. At the same time, the more water on the surface of the ore is blown off by the blown air flow and then conveyed and discharged, which helps to accelerate the subsequent drying process of the ore surface. By setting the differential adjusting assembly 2, the actuating assembly 1 rotates at a differential speed relative to the washing cylinder 4. Through the design of differential rotation, the complexity of the movement track of the ore inside the washing cylinder 4 is increased, so that the ore can be stirred from multiple angles and directions during the cleaning process, and the ore can contact the cleaning water more fully, ensuring that the cleaning water can penetrate into more fine gaps of the ore, and further improving the overall cleaning effect and efficiency.

[0037] Further, as Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 9As shown, it is worth specifically explaining that the boosting component 1 includes an inner tube 101 inserted at the center inside the ore washing cylinder 4 and capable of rotating. One end of the inner tube 101 is communicated with an air inlet pipe 104. The end of the inner tube 101 is rotatably connected to the air inlet pipe 104 through a bearing. A plurality of equally spaced adjusting plates 102 are fixed on the outer side wall of the inner tube 101. During specific operation, the rotating inner tube 101 drives the plurality of adjusting plates 102 to continuously turn over the ore inside the ore washing cylinder 4, improving the even distribution of the ore, reducing the accumulation of the ore, effectively increasing the movement degree of the ore inside the ore washing cylinder 4, ensuring that the ore always remains in a dynamic state during the cleaning process, which not only helps the soil and impurities on the ore surface to gradually fall off, but also significantly improves the comprehensiveness of the ore surface exposure, enabling the cleaning water to evenly contact more positions on the ore surface, improving the evenness and comprehensiveness of the contact between the cleaning water and the ore, and thus effectively improving the overall ore washing effect.

[0038] Further, as Figure 10 and Figure 11 shown, it is worth specifically explaining that an inner cavity 107 communicating with the inside of the inner tube 101 is opened inside the adjusting plate 102. An air blowing hole 105 communicating with the inner cavity 107 is opened on the side surface of the adjusting plate 102. A plurality of the air blowing holes 105 are provided, and the plurality of air blowing holes 105 are equally spaced. During specific operation, the air inlet pipe 104 is externally connected to an air pump, and the airflow with a certain air pressure is conveyed into the inside of the inner tube 101 through the air inlet pipe 104. The airflow inside the inner tube 101 is synchronously shunted and conveyed into the inner cavities 107 of the plurality of adjusting plates 102, and is evenly blown out onto the ore surface through the plurality of air blowing holes 105. Thus, while turning over the ore, the airflow is evenly blown onto the ore surface, and the stubborn impurities adhered to the ore surface are specifically cleaned by the airflow, realizing the auxiliary cleaning of the ore surface. Through the combination of the airflow blowing and the turning-over action, the falling-off efficiency of the impurities on the ore surface is greatly improved, especially for the impurities with higher adhesiveness, which has a significant cleaning effect, further improving the ore washing quality and the overall ore washing effect. At the same time, after the more water on the ore surface is blown off by the blown airflow and then conveyed and discharged, it helps to accelerate the subsequent drying treatment of the ore surface. At the same time, during the position change of the adjusting plate 102, when the adjusting plate 102 moves to be close to the water pipe 9, the airflow blown out from the air blowing holes 105 on the adjusting plate 102 blows and cleans the part of the ore accumulated above the water pipe 9, avoiding the situation where the ore accumulates and stays above the water pipe 9, and saving the operation that the artificial needs to often clean the ore accumulated above the water pipe 9.

[0039] Further, as Figure 8As shown, it is worth explaining in detail that a convex plate 106 is fixed on the side of the dial plate 102, and the convex plate 106 is provided with multiple convex plates 106 and the multiple convex plates 106 are staggered with the blowing holes 105; during specific operation, the convex plates 106 are provided to effectively increase the gap between the side of the dial plate 102 and the surface of the ore, thereby ensuring the smoothness of the airflow blown out of the blowing holes 105, and improving the cleaning effect of the airflow on the ore surface.

[0040] Further Figure 1 and Figure 3 As shown, it is worth specifically explaining that the differential adjustment component 2 includes a shaft 203 rotatably connected to the side wall of the bracket plate 5, a first gear ring 201 is fixed to one end of the ore washing cylinder 4, a first gear 202 meshingly connected to the first gear ring 201 is fixed to the shaft 203, and pulleys 204 are fixed to the ends of the built-in tube 101 and the shaft 203, and a belt 205 is connected between the two pulleys 204; when working, the first gear ring 201 is driven to rotate synchronously by rotating the ore washing cylinder 4, thereby driving the shaft 203 through the cooperation of the first gear ring 201 and the first gear 202. The two pulleys 204 and the belt 205 cooperate to drive the internal tube 101 to rotate, and the first gear 202 and the first gear ring 201 cooperate to make the internal tube 101 and the ore-washing barrel 4 rotate differentially relative to each other, so that the dial plate 102 rotates differentially relative to the ore-washing barrel 4, further increasing the complexity of the movement trajectory of the ore in the ore-washing barrel 4, so that the ore can be dialed in multiple directions during the cleaning process, and the ore can be more fully in contact with the cleaning water, ensuring that the cleaning water can penetrate into more tiny gaps in the ore, further improving the overall cleaning effect and efficiency.

[0041] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the driving component 3 includes a second gear ring 301 fixed on the outer wall of the ore washing barrel 4, and a driving motor 303 is arranged at the bottom of the ore washing barrel 4. A second gear 302 meshingly connected with the second gear ring 301 is fixed on the output end of the driving motor 303; during specific operation, the second gear 302 is driven to rotate by the output end of the driving motor 303, so that the ore washing barrel 4 is driven to rotate by the cooperation of the second gear 302 and the second gear ring 301, so that the spiral push plate 11 inside the ore washing barrel 4 transports the ore.

[0042] This solution has the following working process: The output end of the driving motor 303 drives the second gear 302 to rotate, thereby driving the ore washing cylinder 4 to rotate through the cooperation of the second gear 302 and the second gear ring 301. The spiral push plate 11 inside the rotating ore washing cylinder 4 continuously conveys the ore forward. Water flow with a certain hydraulic pressure is conveyed into the water pipe 9 and sprayed out through multiple spray nozzles 10 onto the ore at the bottom of the ore washing cylinder 4, thereby washing the ore. During this process, the rotating ore washing cylinder 4 drives the first gear ring 201 to rotate synchronously, thereby driving the shaft rod 203 to rotate synchronously through the cooperation of the first gear ring 201 and the first gear 202. Furthermore, the built-in pipe 101 is driven to rotate through the cooperation of two belt pulleys 204 and a belt 205. Through the cooperation of the first gear 202 and the first gear ring 201, the built-in pipe 101 and the ore washing cylinder 4 rotate at a relative differential speed, so that multiple dialing plates 102 perform differential flipping on the ore in the ore washing cylinder 4, improving the uniformity of ore dispersion, reducing the accumulation of ore, effectively increasing the movement degree of the ore inside the ore washing cylinder 4. An air flow with a certain air pressure is conveyed into the interior of the built-in pipe 101 through the air inlet pipe 104. The air flow inside the built-in pipe 101 is synchronously shunted and conveyed into multiple dialing plates 102 through the inner cavity 107 and evenly blown out onto the ore surface through multiple air blowing holes 105, so that while flipping the ore, an air flow is evenly blown out onto the ore surface, and the impurities adhered to the ore surface are assisted in cleaning through the air flow. Through the combination of air flow blowing and flipping actions, the ore is assisted in ore washing.

[0043] Further, as Figure 8 and Figure 10 shown, it is specifically worth noting that multiple said air blowing holes 105 are all arranged obliquely; during specific work, through the obliquely arranged air blowing holes 105, the obliquely blown air flow can quickly blow the ore out from the side of the dialing plate 102, greatly reducing the residual accumulation of ore on the dialing plate 102.

[0044] Further, as Figure 1 and Figure 2 shown, it is specifically worth noting that the bottom ends of two said support plates 5 are jointly fixed with a bottom plate 6. A first support plate 7 is fixed on the top surface of the bottom plate 6. One end of the built-in pipe 101 is rotatably connected to the first support plate 7. A second support plate 8 is fixed on the outer side wall of the support plate 5. One end of the water pipe 9 is rotatably connected to the second support plate 8.

[0045] In summary: By means of the arranged agitation component 1, the ore inside the ore washing cylinder 4 is continuously turned over, improving the uniformity of ore dispersion, reducing the accumulation of ore, effectively increasing the degree of movement of the ore inside the ore washing cylinder 4, ensuring that the ore always remains in a dynamic state during the washing process. This not only helps the soil and impurities on the ore surface to gradually fall off, but also significantly improves the comprehensiveness of the ore surface exposure, enabling the washing water to evenly contact more positions on the ore surface, improving the uniformity and comprehensiveness of the contact between the washing water and the ore, thereby effectively improving the overall ore washing effect. Further, by arranging the agitation component 1 to evenly blow out air flow onto the surface of the ore while turning over the ore, the stubborn impurities adhering to the ore surface are specifically cleaned by the air flow, realizing the auxiliary cleaning of the ore surface. Through the combination of air flow blowing and turning over actions, the shedding efficiency of the impurities on the ore surface is greatly improved, especially for the impurities with higher adhesion, significantly improving the ore washing quality and the overall ore washing effect. At the same time, after blowing out most of the water on the ore surface by the air flow, the ore is conveyed and discharged, which helps to accelerate the subsequent drying process of the ore surface; by arranging the differential adjustment component 2, the agitation component 1 rotates at a differential speed relative to the ore washing cylinder 4. Through the design of differential rotation, the complexity of the movement track of the ore inside the ore washing cylinder 4 is increased, enabling the ore to be stirred from multiple angles and directions during the washing process, and the ore can contact the washing water more fully, ensuring that the washing water can penetrate into more fine gaps of the ore, further improving the overall washing effect and efficiency.

[0046] The drive motor 303 can be purchased on the market. The drive motor 303 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
