Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a centrifugal mineral processing equipment. Background Technology
[0002] Mineral resources are non-renewable resources. With continuous human exploitation, the reserves of rich mineral resources are decreasing, and the characteristics of mineral resources being poor, fine, and complex are becoming increasingly prominent. The separation of low-grade, fine-grained, and difficult-to-process ores is receiving more and more attention. The useful minerals in these ores are embedded in very fine particles, some even reaching the micron level. This requires the use of ultrafine grinding to liberate them into individual particles. However, the low density difference between particles and the fine liberation particle size make it difficult to achieve separation using traditional gravity separation methods. Establishing an effective composite force field and strengthening the separation process are important technologies for improving the efficiency of fine-grained separation. Centrifugal concentrators are devices that perform gravity separation of mineral particle groups in a centrifugal force field. They are one of the most efficient gravity separation devices.
[0003] However, most existing centrifugal mineral processing equipment does not typically protect the inside of the outer shell. Therefore, when the centrifugal force throws the ore out, the ore directly impacts the inner wall of the outer shell, which not only generates significant noise but also damages the outer shell, thus reducing the service life of the equipment. In view of this, a centrifugal mineral processing equipment is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a centrifugal mineral processing equipment that can solve the problem that most existing centrifugal mineral processing equipment usually do not protect the inside of the outer shell. Therefore, when the centrifugal force throws the ore out, the ore directly hits the inner wall of the outer shell, which not only generates a lot of noise, but also damages the outer shell, thus reducing the service life of the equipment.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a centrifugal mineral processing device, including a support frame, wherein a separation cylinder is fixedly connected inside the support frame, and a sealing cover is provided on the separation cylinder;
[0006] The separator cylinder is fixedly connected to a support ring, and the inner separator liner is rotatably connected to the inside of the support ring.
[0007] A first discharge pipe is fixedly connected to the support frame, and a second discharge pipe is rotatably connected to the bottom of the separator cylinder. The second discharge pipe is fixedly connected to the separator inner liner and they are interconnected.
[0008] A buffer mechanism is installed on the inner wall of the separator, a valve is installed on the second discharge pipe, and a drive assembly is installed on the support frame.
[0009] Preferably, the buffer assembly includes a buffer plate, which is disposed inside the separation cylinder, and a buffer pad is fixedly connected to the side of the buffer plate near the separation cylinder.
[0010] The inner wall of the separator is provided with a buffer groove, and a buffer rod is slidably connected inside the buffer groove. The buffer rod passes through the buffer pad and is fixedly connected to the buffer plate.
[0011] A buffer spring is fixedly connected to the inner wall of the buffer groove, and the other end of the buffer spring is fixedly connected to the buffer rod.
[0012] Preferably, the drive assembly includes a servo motor, which is fixedly connected to the support frame. A sprocket is fixedly connected to the output end of the servo motor, and a similar sprocket is fixedly sleeved on the second discharge pipe. A chain is meshed with the sprocket.
[0013] Preferably, the interior of the cushioning pad is honeycomb-shaped.
[0014] Preferably, both the buffer pad and the buffer plate are circular and are composed of arc-shaped plates.
[0015] Preferably, the first discharge pipe is inclined and communicates with the interior of the separation cylinder.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] (1) When the centrifugal mineral processing equipment rotates, the small pieces of ore thrown out will hit the buffer plate under the action of centrifugal force. At this time, the buffer plate will be squeezed by the buffer pad, so the buffer pad will shrink. While the buffer plate is under force, the buffer rod will slide into the buffer tank and squeeze the buffer spring. Therefore, the elasticity of the buffer spring will buffer the impact force, thereby avoiding the ore from being thrown out directly and hitting the inside of the separation cylinder. At the same time, it will avoid the generation of noise during the separation process, thus improving the service life of the equipment.
[0018] (2) The centrifugal mineral processing equipment provides a good deformation space for the buffer pad by setting the interior of the buffer pad to a honeycomb shape, thereby improving the buffer pad's buffering capacity. At the same time, the honeycomb shape has a good sound absorption function, thus isolating noise. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0029] Please see Figure 1-4 This utility model provides a technical solution: a centrifugal mineral processing equipment, including a support frame 1, a separation cylinder 2 fixedly connected inside the support frame 1, and a sealing cover 3 provided on the separation cylinder 2;
[0030] A support ring 10 is fixedly connected inside the separator cylinder 2, and a separator inner liner 9 is rotatably connected inside the support ring 10.
[0031] A first discharge pipe 4 is fixedly connected to the support frame 1. The first discharge pipe 4 is inclined and communicates with the interior of the separation cylinder 2. A second discharge pipe 5 is rotatably connected to the bottom of the separation cylinder 2. The second discharge pipe 5 is fixedly connected to the separation inner liner 9 and communicates with it.
[0032] A buffer mechanism is provided on the inner wall of the separator 2, a valve is provided on the second discharge pipe 5, and a drive assembly is provided on the support frame 1;
[0033] When centrifugal separation of ore is required, the sealing cover 3 is opened and the ore is put into the separation inner tank 9. At this time, the separation inner tank 9 is controlled to rotate by the drive component. During the rotation, the separation inner tank 9 throws out small pieces of ore, while larger pieces of ore are intercepted inside the separation inner tank 9. The buffer mechanism can prevent the thrown-out ore from directly hitting the inner wall of the separation cylinder 2, thus avoiding noise generation and preventing damage to the separation cylinder 2 under long-term impact.
[0034] Furthermore, the drive assembly includes a servo motor 7, which is fixedly connected to the support frame 1. A sprocket 6 is fixedly connected to the output end of the servo motor 7. The same sprocket 6 is fixedly sleeved on the second discharge pipe 5. A chain 8 is meshed on the sprocket 6.
[0035] When the inner liner 9 needs to be rotated, the servo motor 7 is started. The output end of the servo motor 7 drives the sprocket 6 and the chain 8 to rotate, thus driving the second discharge pipe 5 to rotate. In turn, the second discharge pipe 5 drives the inner liner 9 to rotate, thus completing the centrifugal separation of minerals in the inner liner 9.
[0036] Furthermore, the buffer assembly includes a buffer plate 11, which is disposed inside the separation cylinder 2, and a buffer pad 12 is fixedly connected to the side of the buffer plate 11 near the separation cylinder 2.
[0037] A buffer groove 13 is provided on the inner wall of the separation cylinder 2. A buffer rod 14 is slidably connected inside the buffer groove 13. The buffer rod 14 passes through the buffer pad 12 and is fixedly connected to the buffer plate 11.
[0038] A buffer spring 15 is fixedly connected to the inner wall of the buffer groove 13, and the other end of the buffer spring 15 is fixedly connected to the buffer rod 14.
[0039] When the inner tank 9 rotates, the small pieces of ore that are thrown out collide with the buffer plate 11 under the action of centrifugal force. At this time, the buffer plate 11 is compressed against the buffer pad 12, so the buffer pad 12 contracts. While the buffer plate 11 is under force, the buffer rod 14 slides into the buffer groove 13 and compresses the buffer spring 15. Therefore, the elasticity of the buffer spring 15 buffers the impact force, thereby preventing the ore from being thrown out directly and impacting the inside of the separation cylinder 2, and at the same time avoiding the generation of noise during the separation process.
[0040] Furthermore, the interior of the cushioning pad 12 is honeycomb-shaped;
[0041] By setting the interior of the buffer pad 12 to a honeycomb structure, a good deformation space is provided for the buffer pad 12, thus improving the buffering capacity of the buffer pad 12. At the same time, the honeycomb structure has a good sound absorption function, thus isolating noise.
[0042] Furthermore, both the buffer pad 12 and the buffer plate 11 are circular and are composed of multiple arc-shaped plates.
[0043] By combining the cushioning pad 12 and the cushioning plate 11 with multiple curved plates, each cushioning pad 12 and the cushioning plate 11 can move independently, thereby ensuring the cushioning effect.
[0044] Working principle: When the inner liner 9 needs to be rotated, the servo motor 7 is started. The output end of the servo motor 7 drives the sprocket 6 and the chain 8 to rotate, thus driving the second discharge pipe 5 to rotate. In turn, the second discharge pipe 5 drives the inner liner 9 to rotate, thus completing the centrifugal separation of minerals in the inner liner 9.
[0045] When the inner tank 9 rotates, the small pieces of ore that are thrown out collide with the buffer plate 11 under the action of centrifugal force. At this time, the buffer plate 11 is compressed against the buffer pad 12, so the buffer pad 12 contracts. While the buffer plate 11 is under force, the buffer rod 14 slides into the buffer groove 13 and compresses the buffer spring 15. Therefore, the elasticity of the buffer spring 15 buffers the impact force, thereby preventing the ore from being thrown out directly and impacting the inside of the separation cylinder 2, and at the same time avoiding the generation of noise during the separation process.
[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
