Description

Technical Field

[0001] This invention relates to the field of ore washing machine technology, specifically a drum ore washing machine. Background Technology

[0002] As is widely known, a drum washing machine is a common type of mining equipment, mainly used to wash and separate useful components from ore. The working principle of a drum washing machine is to use rotating drums to clean and screen the ore, achieving grading and separation of the ore based on the different physical properties and particle sizes of various minerals.

[0003] For example, the invention patent with application publication number CN114101181B, application publication date June 20, 2025, entitled "An Immersion Drum Washing Machine", includes a horizontal washing drum, a filter drum coaxially connected to the discharge end of the washing drum, a baffle plate coaxially rotatably installed at the feed end of the washing drum, a columnar water tank coaxially arranged inside the washing drum, water spray heads evenly distributed on the side wall of the water tank, a water inlet channel connected to the end of the water tank facing away from the filter drum, the water inlet channel passing through the baffle plate and connected to a pressure water pump, a feed channel also connected to the baffle plate, a sealing plate coaxially arranged at the discharge end of the filter drum, the sealing plate slidingly arranged inside the washing drum, a waterproof rotating motor installed at the end of the water tank facing the filter drum, a threaded rod installed at the rotating end of the rotating motor and passing through the axis of the filter drum, the threaded rod being threadedly connected to the sealing plate, and a limiting rod parallel to the threaded rod installed at the end of the water tank facing the filter drum; this invention aims to solve the problem of poor washing capacity in existing drum washing machines.

[0004] The shortcoming of the existing technology is that the drum washing machine generally uses lifting plates to bring the ore to a high place inside the drum, and then lets the ore fall freely and collide with the ore in the lower half of the inner side of the drum, thereby forcing the soil attached to the surface of the ore to peel off. However, the surface of the ore in the lower half of the inner side of the drum is also attached with soil. This soil will buffer the collision between the ore, resulting in insufficient impact force and making it difficult for the soil on the surface to fall off. Summary of the Invention

[0005] The purpose of this invention is to provide a drum washing machine to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drum washing machine, comprising a mounting shell and an inner drum rotatably mounted on the mounting shell, wherein the inner drum is provided with: Multiple pusher blade groups, comprising multiple inner pusher blades fixedly mounted on the inner roller and extending along a spiral, wherein the cross-section of each inner pusher blade is arc-shaped and combines with the inner wall of the inner roller to form a hopper, wherein: The inner pusher plate moves to a high position with the inner roller and throws ore so that the ore collides with the back of the inner pusher plate on the opposite side.

[0007] As a further description of the above technical solution: a return plate group is provided between the two pusher plate groups near the inner roller feed end, the return plate group including an inner return plate corresponding to the inner pusher plate of the adjacent pusher plate group and with the opposite spiral direction.

[0008] As a further description of the above technical solution: the end of the inner return material sheet abuts against the middle of the adjacent inner push material sheet.

[0009] As a further description of the above technical solution: the inner roller is provided with an outer roller that is coaxially distributed and has a hole diameter smaller than that on its side wall, and the inner pusher plate and the inner return plate are respectively provided with an outer pusher plate and an outer return plate extending between the inner roller and the outer roller.

[0010] As a further description of the above technical solution: the inner return material plate and the outer return material plate are staggered and a second mounting rod is provided between them. The second mounting rod is provided with a feeding port for the outer ore to return to the inner drum.

[0011] As a further description of the above technical solution: the external return material sheet is specifically composed of multiple stepped storage platforms connected together, and the top height of the storage platform decreases along its top diagonal and the lowest point is directly opposite the feeding port.

[0012] As a further description of the above technical solution: the side wall of the outer pusher plate is provided with a pusher plate that fits against the outer roller and is used to restrict the ore.

[0013] As a further description of the above technical solution: the mounting shell is provided with a scraper that fits against the outer wall of the outer roller, and the scraper is movably provided with movable strips for pushing the soil.

[0014] As a further description of the above technical solution: the movable strip is provided with a support block that penetrates the scraper and whose top end is attached to the outer wall of the outer roller.

[0015] As a further description of the above technical solution: when one of the inner pusher plates throws ore, the pusher plate on the outer pusher plate on the opposite side is directly opposite the support block.

[0016] In the above technical solution, the drum washing machine provided by the present invention has the following beneficial effects: During the ore washing process, the feeding equipment continuously feeds the ore into the inner drum, the water spray pipe sprays water to wash the ore, and the drive wheel drives the inner drum to rotate. When there is little mud adhering to the surface of the ore, the water sprayed from the water spray pipe can directly clean the ore. At this time, the adhesion between the ore and the inner push plate on the push plate assembly is small, and it can slide along the spiral-shaped inner push plate, and then move along the inner push plate towards the discharge end of the inner drum, thereby allowing the clean ore to be discharged quickly. When there is a lot of mud adhering to the surface of the ore, the water sprayed from the water spray pipe cannot clean the ore. After the stone is cleaned, the ore adheres to the inner pusher plate due to the mud on its surface. The inner pusher plate, with its arc-shaped cross-section, combines with the inner wall of the inner roller to form a hopper that lifts the ore, carrying it to a high position. At the highest point, the ore is thrown out, moving along the arc surface of the inner pusher plate and falling. At this time, the inner pusher plate on the opposite side happens to move into the path of the falling ore, and the ore at the bottom of the inner side of the inner roller is blocked by the inner pusher plate. The ore collides with the back of the inner pusher plate without any cushioning, so that the ore can be separated from the mud on its surface. The vibration during the collision will also shake off the mud attached to the front of the inner pusher plate, ensuring that the inner pusher plate can work normally. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-11 This invention provides a technical solution: a drum washing machine, comprising a mounting shell 1 and an inner drum 11 rotatably mounted on the mounting shell 1, the inner drum 11 being provided with: Multiple pusher blade groups 13 include multiple inner pusher blades 131 fixedly mounted on the inner roller 11 and extending along a spiral. The cross-section of the inner pusher blades 131 is arc-shaped and combines with the inner wall of the inner roller 11 to form a hopper, wherein: The inner pusher plate 131 moves to a high position with the inner roller 11 and throws ore so that the ore collides with the back of the inner pusher plate 131 on the opposite side.

[0022] Specifically, the interior of the mounting shell 1 is symmetrically equipped with a water spray pipe 16 for spraying water to its inner side and a drive wheel for driving the inner roller 11 to rotate. The side wall of the inner roller 11 is a mesh structure. According to the figure, the right side of the inner roller 11 is the feeding end and the left side is the discharging end.

[0023] Furthermore, during the ore washing process, the feeding equipment continuously feeds the ore into the inner drum 11, and the water spray pipe 16 sprays water to wash the ore. The drive wheel drives the inner drum 11 to rotate. When there is little mud adhering to the ore surface, the water sprayed from the water spray pipe 16 can directly clean the ore. At this time, the adhesion between the ore and the inner pusher plate 131 on the pusher plate assembly 13 is small, and it can slide along the spiral-shaped inner pusher plate 131, and then move along the inner pusher plate 131 towards the discharge end of the inner drum 11, so that the clean ore can be discharged quickly. When there is a lot of mud adhering to the ore surface, the water sprayed from the water spray pipe 16 cannot clean the ore. At this time, the mud on the ore surface... The soil adheres to the inner pusher plate 131 under the action of the soil. The inner pusher plate 131 with an arc-shaped cross-section and the inner wall of the inner roller 11 form a hopper that lifts the ore, moves the ore to a high place, and throws the ore when it reaches the highest point. The ore moves along the arc surface of the inner pusher plate 131 and falls. At this time, the inner pusher plate 131 on the opposite side just moves into the falling path of the ore. Moreover, the ore at the bottom of the inner side of the inner roller 11 is blocked by the inner pusher plate 131. The ore collides with the back of the inner pusher plate 131. There is no buffer during the collision process so that the ore can be separated from the soil on its surface. The vibration during the collision will also shake off the soil attached to the front of the inner pusher plate 131, ensuring that the inner pusher plate 131 can work normally.

[0024] In another embodiment of the present invention, a return plate group 14 is provided between two pusher plate groups 13 near the feed end of the inner roller 11. The return plate group 14 includes an inner return plate 141 that corresponds to the inner pusher plate 131 of the adjacent pusher plate group 13 and has the opposite spiral direction. The end of the inner return plate 141 abuts against the middle of the adjacent inner pusher plate 131.

[0025] Specifically, during operation, both the mounting shell 1 and the inner roller 11 are arranged at an angle, with the feed end of the inner roller 11 being higher. The rotation of the inner roller 11 drives the pusher plate group 13 and the return plate group 14 to rotate. The inner pusher plates 131 on the pusher plate group 13 push the ore towards the discharge end of the inner roller 11. Meanwhile, the inner return plates 141 on the return plate group 14, located between the two pusher plate groups 13 near the feed end of the inner roller 11, block a portion of the ore, thus prolonging the residence time of this portion of the ore in the inner roller 11. This allows the water spray pipe 16 to continuously wash this portion of the ore, improving its cleanliness. Furthermore, the end of the inner return plate 141 is adjacent to the inner pusher plate 131. The middle part abuts, forming a "√" shaped structure at the abutment point, which can accumulate ore to lift it to a higher position. Smaller ore particles can continue to move towards the discharge end of the inner drum 11 through the gap at the abutment point along the inner pusher plate 131, avoiding excessive retention and breakage of small ore particles, thus increasing ore loss. The inner drum 11 continues to rotate, and the "√" shaped structure lifts and throws the ore. However, since the inner drum 11 is arranged at an angle, the part of the ore that is lifted and thrown will be offset from the inner pusher plate 131 on the opposite side and will only collide with the back of the inner return plate 141. It will be guided by the arc surface of the back of the inner return plate 141 to move towards the discharge end of the inner drum 11, thereby allowing the ore to be discharged from the discharge end of the inner drum 11.

[0026] In another embodiment of the present invention, an outer roller 12 coaxially distributed on the inner roller 11 and having a hole diameter smaller than that on its side wall is provided, and an outer pusher 132 and an outer return 142 extending between the inner roller 11 and the outer roller 12 are respectively provided on the inner pusher 131 and the inner return 141.

[0027] Specifically, the outer roller 12 is fixedly mounted on the inner roller 11, and the outer pusher plate 132 and the inner pusher plate 131 extend along the same spiral.

[0028] Furthermore, during operation, the inner roller 11 drives the outer roller 12 to rotate synchronously. Smaller ore particles in the inner roller 11 pass through the gaps in the inner roller 11 and enter the space between the inner roller 11 and the outer roller 12. As the outer roller 12 rotates, smaller ore particles move upwards with it. The outward pushing plate 132 on the inner roller 11 moves synchronously with the outer roller 12. The outer roller 12 continues to rotate, causing the ore to separate from it. The outward pushing plate 132 and the outward returning plate 142 work together to receive the ore. The outward pushing plate 132 guides the ore towards the discharge end of the outer roller 12, accelerating the discharge of small ore particles. This facilitates the rapid passage of the slurry from the inner roller 11 through the outer roller 12 and its discharge.

[0029] In another embodiment of the present invention, the inner return plate 141 and the outer return plate 142 are staggered and a second mounting rod 143 is provided between them. The second mounting rod 143 is provided with a feeding port 145 for the outer ore to return to the inner drum 11. The outer return plate 142 is specifically formed by connecting multiple stepped storage platforms 144, and the top height of the storage platform 144 decreases along its top diagonal and the lowest point is directly opposite the feeding port 145.

[0030] Specifically, in the vertical direction of the same plane, the outer return sheet 142 is located below the inner return sheet 141, and the feed port 145 is located below the inner return sheet 141.

[0031] Furthermore, during the rotation of the inner drum 11 and the outer drum 12, the outward pushing plate 132 and the outward returning plate 142 cooperate to receive the ore. The outward pushing plate 132 guides the ore to move towards the discharge end of the outer drum 12. Small ore particles falling onto the outward returning plate 142 are distributed on multiple stepped storage platforms 144 on the outward returning plate 142, and move towards the feed port 145 along the inclined surface at the top of the storage platform 144. This part of the ore also moves towards the discharge end of the outer drum 12. The small ore particles gather at the connection between the storage platform 144 and the second mounting rod 143. Ore particles that are too small to be effectively collected by the outer drum 12 pass through the feed port 145 on the second mounting rod 143 and return to the inner drum 12. In section 1, the ore in the inner roller 11 rubs against each other, grinding away impurities attached to the surface of the ore. The ore that cannot pass through the feed port 145 continues to move with the inner roller 11. When it reaches the highest point of the inner roller 11, this part of the ore is supported by the second mounting rod 143. The inner roller 11 continues to move until it reaches the upper part of the inner roller 11. At this time, the ore on the second mounting rod 143 rolls down and moves along the surface of the inner roller 11. The ore collides with the frame of the inner roller 11 and bounces outward. The ore is not easy to return to the inner roller 11. Moreover, the mounting shell 1, the inner roller 11 and the outer roller 12 are all arranged at an angle. When the ore falls, it will also move towards the discharge end of the outer roller 12 near the mounting rod under the action of gravity.

[0032] In another embodiment of the present invention, a pusher 134 is provided on the side wall of the outer pusher 132, which fits against the outer roller 12 and is used to restrict the ore.

[0033] Specifically, the pusher 134 is located on the sidewalls of the outer pusher 132 on opposite sides.

[0034] Furthermore, during the rotation of the inner roller 11 and the outer roller 12, the outer pusher plate 132 with pusher plate 134 can support more ore and can receive the water flow sprayed from the water spray pipe 16, thereby guiding the ore between the inner roller 11 and the outer roller 12 to move and come into contact with the water flow. While cleaning this part of the ore, it guides the ore to move towards the discharge end of the outer roller 12, improving the cleanliness of the ore and shortening the residence time of this part of the ore in the outer roller 12.

[0035] In another embodiment of the present invention, a scraper 15 is provided on the mounting shell 1 to fit against the outer wall of the outer roller 12, and a movable strip 151 for pushing the soil is movably provided on the scraper 15.

[0036] Specifically, the movable strip 151 is rotatably mounted on the scraper 15.

[0037] Furthermore, when there is a lot of soil attached to the surface of the ore, the ore gradually peels off the soil under the impact of collision and water flow. The soil passes through the inner roller 11 and adheres to the outer roller 12 with smaller mesh. During the rotation of the outer roller 12, the scraper 15 fixedly installed on the mounting shell 1 can scrape off the soil on the outer surface of the outer roller 12, causing the soil on the inner surface of the outer roller 12 to lose support and be washed away by the water flow. During this process, the movable strip 151 on the scraper 15 moves intermittently, pushing the soil scraped off the outer roller 12 and attached to the scraper 15, thereby separating this part of the soil from the scraper 15 and avoiding excessive soil accumulation on the scraper 15, which would affect its normal operation.

[0038] In another embodiment of the present invention, a support block 152 is provided on the movable strip 151, which penetrates the scraper 15 and has its top end attached to the outer wall of the outer roller 12. When one of the inner pusher plates 131 throws ore, the pusher plate 134 on the opposite side of the outer pusher plate 132 faces the support block 152.

[0039] Specifically, a first mounting rod 133 is provided between the inner pusher plate 131 and the outer pusher plate 132, and both ends of the first mounting rod 133 are hinged to the inner roller 11.

[0040] Furthermore, when there is a lot of soil attached to the surface of the ore, the ore moves to a high point with the inner pusher plate 131 and is thrown. The thrown ore collides with the inner pusher plate 131 on the opposite side, and the inner pusher plate 131 drives the outer pusher plate 132 to swing through the first mounting rod 133. During the swinging process, the pusher plate 134 on the side of the outer pusher plate 132 will collide with the outer roller 12, causing the outer roller 12 to vibrate and shake off the soil attached to its mesh. At this time, the support block 152 is facing the pusher plate 134 on the outer pusher plate 132. The pusher plate 134 transmits the vibration to the support block 152 through the outer roller 12, which in turn causes the support block 152 to drive the movable strip 151 to move slightly relative to the scraper 15. The movable strip 151 pushes the soil attached to the surface of the scraper 15, causing the soil to loosen and then separate from the scraper 15 under the flushing of the water flow.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
