[0026] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail by combining with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.
[0027] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model based on the specific circumstances.
[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0029] The following is combined Figures 1 to 3 This invention describes a utility model of an anti-blocking alumina feeding and conveying device.
[0030] Please see Figures 1 to 3 This utility model provides an anti-blocking alumina feeding and conveying device, including: a conveying channel 1, a filter element 2, and a clearing component 3. The conveying channel 1 includes a feeding hopper 11 and a fresh chute 12, with the bottom of the feeding hopper 11 connected to one end of the fresh chute 12. The filter element 2 is disposed in the feeding hopper 11 and is used to filter out lumps in the alumina. The clearing component 3 includes a clearing element 31 and a driving unit 32. The clearing element 31 is disposed in the conveying channel 1, and the driving unit 32 is connected to the clearing element 31 and is used to drive the clearing element 31 to move in order to push the alumina.
[0031] Specifically, by installing a filter element 2 inside the hopper 11, the alumina is filtered before reaching the discharge port of the fresh chute 12. After the filter element 2 removes larger lumps, the remaining smaller alumina particles can pass smoothly through the junction of the hopper 11 and the fresh chute 12, reducing the possibility of blockage at the discharge port of the fresh chute 12. The filter element 2 is located inside the hopper 11, which is wider at the top and narrower at the bottom. The bottom opening size of the hopper 11 is the same as the discharge port size of the fresh chute 12. Therefore, the area of the filter element 2 is larger than the area of the discharge port of the fresh chute 12, resulting in a better filtration effect.
[0032] In addition, even if the filtered alumina still blocks the discharge port of the fresh chute 12, the unblocking component 31 can be moved by the drive unit 32, so that the unblocking component 31 can push the blocked alumina, thereby allowing the alumina to pass smoothly through the discharge port of the fresh chute 12 under the action of gravity, and completing the unblocking of the conveying channel 1.
[0033] The fresh chute 12 is provided with the filter piece 2 above the discharge port, so that the block-shaped objects in the alumina are filtered, thereby reducing the probability that the discharge port of the fresh chute 12 is blocked.
[0034] Please refer to Figures 1 to 2 In some embodiments, the conveying channel 1 has a first inner wall, the dredging piece 31 is adapted to the first inner wall, the dredging piece 31 has a first state and a second state, and the driving unit 32 is used to drive the dredging piece 31 to move, so as to switch the dredging piece 31 between the first state and the second state; in the first state, the dredging piece 31 is adjacent to or closely fitted with the first inner wall; in the second state, the dredging piece 31 is away from the first inner wall.
[0035] Specifically, the first inner wall is the inner side wall of one side of the conveying channel 1. In the natural state, the dredging piece 31 is in the first state, and the dredging piece 31 is close enough to the first inner wall or even fitted with the first inner wall, so that the alumina in the conveying channel 1 is located on the side of the dredging piece 31 away from the first inner wall. When the conveying channel 1 is blocked, the driving unit 32 drives the dredging piece 31 to switch between the first state and the second state, and the dredging piece 31 swings back and forth to dredge the conveying channel 1.
[0036] In some embodiments, in the first state, the dredging piece 31 does not contact the first inner wall, so as to avoid abrasion of the dredging piece 31.
[0037] In some other embodiments, in the first state, the dredging piece 31 is fitted with the first inner wall, so that when the dredging piece 31 changes from the second state to the first state, the dredging piece 31 will hit the first inner wall, so that the dredging piece 31 slightly vibrates with the conveying channel 1. Through the vibration, the alumina pushed by the dredging piece 31 falls smoothly, thereby restoring the conduction of the conveying channel 1.
[0038] Please refer to Figures 1 to 2 In some embodiments, the anti-blocking alumina discharging conveying device further comprises a guide plate 4, the guide plate 4 is inclinedly arranged in the conveying channel 1, the guide plate 4 is at least partially located above the dredging piece 31, and the guide plate 4 is used to guide the alumina above the dredging piece 31 to the side of the dredging piece 31 away from the first inner wall.
[0039] Specifically, the higher end of the flow guide plate 4 is connected with the first inner wall, the lower end of the flow guide plate 4 is lower than the top of the dredging piece 31, and no matter the dredging piece 31 is in the first state or the second state, the lower end of the flow guide plate 4 is always on the side of the dredging piece 31 away from the first inner wall. By setting the flow guide plate 4, the alumina above the dredging piece 31 is guided to the side of the dredging piece 31 away from the first inner wall, so as to avoid the alumina above the dredging piece 31 from falling between the dredging piece 31 and the first inner wall.
[0040] Please refer to Figures 1 to 3 In some embodiments, the driving unit 32 includes a push plate 321, a guide column, a spring 322, a mounting frame 323, a cam 324, a first rotating shaft 325 and a motor 326. The push plate 321 is arranged on the outside of the conveying channel 1, and the push plate 321 and the dredging piece 31 are connected through the guide column penetrating the conveying channel 1. The spring 322 is sleeved on the guide column, and the spring 322 is located between the push plate 321 and the outer wall of the conveying channel 1. The mounting frame 323 is arranged on the outer wall of the conveying channel 1, the first rotating shaft 325 is rotationally connected with the mounting frame 323, the first rotating shaft 325 is drivingly connected with the motor 326, and the cam 324 is sleeved on the first rotating shaft 325. The motor 326 is used to drive the cam 324 to rotate to press the push plate 321 and the spring 322.
[0041] Specifically, the cam 324 is located on the side of the push plate 321 away from the conveying channel 1. After the motor 326 drives the first rotating shaft 325, the cam 324 rotates with the first rotating shaft 325 and presses the push plate 321, so that the push plate 321 approaches the conveying channel 1. At this time, the dredging piece 31 is away from the first inner wall, and the spring 322 is compressed. With the continuous rotation of the cam 324, the push plate 321 will move away from the conveying channel 1 under the rebounding force of the spring 322, so that the dredging piece 31 approaches the first inner wall. In this embodiment, the cam 324 and the spring 322 cooperate with each other to drive the dredging piece 31 to swing back and forth to dredge the alumina.
[0042] Please refer to Figures 1 to 2 In some embodiments, the dredging piece 31 is partially located in the discharge hopper 11 and the remaining part is located in the fresh chute 12, so that the dredging piece 31 can simultaneously dredge the alumina in the discharge hopper 11 and the fresh chute 12, especially the junction of the discharge hopper 11 and the fresh chute 12.
[0043] Please refer to Figure 1 In some embodiments, the filter 2 includes an upper filter screen 21 and a lower filter screen 22 arranged in an upper-lower interval. The mesh number of the upper filter screen 21 is smaller than that of the lower filter screen 22.
[0044] Specifically, by setting two different height filter screen, thereby layered multiple filtering of alumina, improve the filtering effect. The upper filter screen 21 is used for filtering large blocky material, the lower filter screen 22 is used for filtering blocky material with smaller particle size, the upper filter screen 21 and the lower filter screen 22 can filter the alumina at the same time, improve the filtering efficiency, and the upper filter screen 21 filters out the large blocky material, which can reduce the burden of the lower filter screen 22.
[0045] Please refer to Figures 1 to 2 In some embodiments, the anti-clogging alumina unloading conveying device further comprises a scraper 5, the scraper 5 is arranged between the upper filter screen 21 and the lower filter screen 22, the scraper 5 is connected with the driving unit 32, and the driving unit 32 is also used to drive the scraper 5 to move the alumina on the lower filter screen 22.
[0046] Specifically, since the lower filter screen 22 is used for filtering small particle size blocky material, the mesh size of the lower filter screen 22 is small, and it is easy to be blocked. By setting the scraper 5, the driving unit 32 can move the alumina on the lower filter screen 22 when driving the scraper 5 to move, preventing the alumina from accumulating and blocking the mesh of the lower filter screen 22.
[0047] Please refer to Figure 1 In some embodiments, the lower filter screen 22 is in the shape of a circular arc, and the middle part of the lower filter screen 22 is concave, and the driving unit 32 drives the scraper 5 to rotate to move the alumina on the lower filter screen 22.
[0048] Specifically, by setting the lower filter screen 22 in the shape of a circular arc and the scraper 5 in rotational motion, the edge of the scraper 5 makes circular motion when the scraper 5 rotates, and the edge of the scraper 5 can sweep over the upper part of each part of the lower filter screen 22, thereby fully moving the alumina and avoiding dead angles.
[0049] Please refer to Figures 1 to 3 In this embodiment, the driving unit 32 further comprises a second rotating shaft 327, a belt 328 and two pulleys 329, the second rotating shaft 327 is connected with the scraper 5, the second rotating shaft 327 is rotatably connected with the conveying channel 1, and one end of the second rotating shaft 327 penetrates out of the conveying channel 1. One of the two pulleys 329 is sleeved on the second rotating shaft 327, and the other pulley 329 is sleeved on the first rotating shaft 325, the two pulleys 329 are drivingly connected through the belt 328, when the motor 326 drives the first rotating shaft 325 to rotate, the second rotating shaft 327 also rotates, thereby driving the scraper 5 to rotate.
[0050] In some embodiments, the scraper 5 does not contact the lower filter screen 22 when pushing the alumina, avoiding collision between the scraper 5 and the lower filter screen 22. The edge of the scraper 5 away from the second rotating shaft 327 is as close to the lower filter screen 22 as possible when rotating and sweeping above the lower filter screen 22, so that the scraper 5 can effectively prevent the mesh of the lower filter screen 22 from being blocked.
[0051] In some embodiments, the scraper 5 can be hollowed out, so that the edge of the scraper 5 can push the alumina attached to the lower filter screen 22, and the other parts (such as the middle part) of the scraper 5 can pass through the hollowing and the like to reduce the contact area with the alumina as much as possible, reduce the resistance received by the scraper 5, and also avoid too much alumina being lifted up by the scraper 5.
[0052] In some embodiments, the conveying channel 1 is also provided with an access hole, and the upper part of the filter element 2 communicates with the access hole.
