Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ash slag treatment, in particular to an anti-wear device for aluminum ash discharge. Background Art

[0002] Aluminum ash slag is a waste residue generated during the aluminum industry's production process. It is hazardous and requires harmless treatment and high-value utilization. During treatment, the aluminum ash slag in the raw material bin flows into a bucket elevator, which transports it to subsequent processing equipment.

[0003] The outlet of the raw material bin is connected to the feed hopper on the bucket elevator to realize the transfer of aluminum ash slag. The feed hopper is a triangular hopper, and the side wall where the inclined edge is located is the discharge plate. The aluminum ash slag flowing out of the raw material bin outlet directly impacts the discharge plate downward, and friction is generated between the two. Figure 1 shown.

[0004] Conventional blanking plates are made of smooth, 10mm thick steel. The aluminum slag continuously impacts and rubs the steel during its fall, creating a large amount of aluminum slag throughout the production process. This causes the blanking plates to wear rapidly, and within 2-3 months, the blanking plates can wear and leak, shortening their service life and causing production to cease. Once wear and leakage occur, production must be stopped for repairs, but the repairs are often ineffective. Summary of the Invention

[0005] In order to solve the problem that the blanking plate is easily affected by the impact and wear of aluminum ash slag and causes leakage, the utility model provides an anti-wear device for aluminum ash blanking. A plurality of intercepting plates are arranged on the blanking plate to block the aluminum ash slag, and then a certain thickness of aluminum ash slag layer is formed above the blanking plate. The falling aluminum ash slag impacts the material layer, thereby ensuring that the blanking plate is not worn.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0007] An anti-wear device for aluminum ash discharge is installed on the feed hopper of a bucket elevator. The feed hopper is provided with an inclined discharge plate, including a rear cover, an anti-wear plate and an interception component.

[0008] The rear cover is detachably arranged on the feed hopper, which is convenient for disassembly of the rear cover. The rear cover corresponds to the blanking plate, and the rear cover is covered with the blanking plate, which is convenient for surrounding the blanking plate. The anti-wear plate is adjustably arranged in the rear cover, and the position of the anti-wear plate can be adjusted. The anti-wear plate and the blanking plate are arranged in parallel. The retaining assembly is provided on the anti-wear plate. When the position of the anti-wear plate is adjusted, the retaining assembly moves together, and the upper part of the retaining assembly passes through the anti-wear plate and extends into the feed hopper;

[0009] The intercepting component includes multiple rows of intercepting plates arranged vertically. The number of intercepting plates in each row is multiple and arranged at intervals, facilitating the coverage of the intercepting plates on the wear-resistant plate. The intercepting plates are perpendicular to the wear-resistant plate. An aluminum ash slag layer accumulates between several intercepting plates, and the aluminum ash slag layer covers the upper surface of the feeding plate, preventing the aluminum ash slag from impacting the feeding plate and facilitating its protection.

[0010] Further, the rear cover is a cover body in the shape of a rectangular groove, facilitating the accommodation of the wear-resistant plate. Long strip-shaped flange plates are provided on two opposite sides of the rear cover, and the rear cover is bolted to the feeding hopper through the flange plates, facilitating the bolt installation of the rear cover and the feeding hopper.

[0011] Further, there is a gap between the feeding plate and the wear-resistant plate vertically. A plurality of adjusting bolts are provided on the bottom surface of the rear cover. The heads of the adjusting bolts extend into the rear cover and abut against the wear-resistant plate. Rotating the adjusting bolts facilitates the adjustment of the position of the wear-resistant plate.

[0012] Further, two adjacent rows of the intercepting plates are arranged vertically offset. Each intercepting plate is bent into a "∨" shape, and the tip of the intercepting plate faces the flowing direction of the aluminum ash slag, improving the intercepting effect of the intercepting plates on the aluminum ash slag. Holes are provided on the feeding plate for the intercepting plates to pass through, facilitating the intercepting plates to extend into the feeding hopper.

[0013] Further, the aluminum ash slag layer is a layer structure with a certain thickness formed by the accumulation of aluminum ash slag on the upper surface of the feeding plate after being intercepted by several intercepting plates, improving the reliability of the protection of the feeding plate.

[0014] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0015] The structure of the present utility model is reasonably designed. Several intercepting plates are arranged on the feeding plate. When the aluminum ash slag falls, it first fills the gaps between the intercepting plates and forms an aluminum ash slag layer with a certain thickness. Then, the subsequent falling aluminum ash slag no longer directly impacts the feeding plate, but impacts the aluminum ash slag layer, thereby protecting the feeding plate from wear, extending the service life of the equipment, reducing the workload of equipment maintenance and repair, and ensuring continuous production.

[0016] The adjusting bolts of the present utility model can control the position of the wear-resistant plate in the rear cover, that is, control the length of the intercepting plate extending into the feeding hopper. When the top of the intercepting plate is worn and the thickness of the aluminum ash slag layer decreases, the adjusting bolts can be rotated to make the intercepting plate extend more into the feeding hopper, ensuring that the aluminum ash slag layer always maintains a certain thickness and guaranteeing the durability of the protection of the feeding plate.

[0023] The following describes the specific embodiments of the utility model in detail with reference to the drawings:

[0024] As Figures 2 to 5 shown, an anti-wear device for alumina ash feeding is installed on the feed hopper 3 of the bucket elevator 2, and an inclined blanking plate 4 is arranged on the feed hopper 3. Through this device, the wear of the blanking plate 4 can be effectively prevented, the service life of the blanking plate 4 can be prolonged, and the continuous and stable production can be ensured.

[0025] The anti-wear device for alumina ash feeding includes a rear cover 5, an anti-wear plate 6 and an intercepting assembly 7. The rear cover 5 is a rectangular groove-shaped cover body, and certain components can be placed inside the rear cover 5. When the rear cover 5 is installed, the rear cover 5 is detachably arranged on the feed hopper 3. Specifically, strip-shaped flange plates 8 are arranged on the two corresponding sides of the rear cover 5, and the rear cover 5 is bolted to the feed hopper 3 through the flange plates 8, thereby realizing the installation of the rear cover 5 and the feed hopper 3.

[0026] After installation, the rear cover 5 corresponds to the blanking plate 4, and the rear cover 5 covers the blanking plate 4, which is equivalent to that the rear cover 5 can surround the blanking plate 4, and the rear cover 5 and the blanking plate 4 are kept parallel.

[0027] An anti-wear plate 6 is adjustably arranged inside the rear cover 5. The anti-wear plate 6 is located between the blanking plate 4 and the rear cover 5. The anti-wear plate 6 and the blanking plate 4 are arranged in parallel, and there is a gap between the blanking plate 4 and the anti-wear plate 6 up and down. The adjustable setting of the anti-wear plate 6 also means that the position of the anti-wear plate 6 inside the rear cover 5 is adjustable, and thus the distance between the anti-wear plate 6 and the blanking plate 4 can be changed.

[0028] The adjusting means for the wear-resistant plate 6 is as follows: A plurality of adjusting bolts 9 are provided on the bottom surface of the rear cover 5. The head of the adjusting bolt 9 extends into the rear cover 5 and abuts against the wear-resistant plate 6. The adjusting bolt 9 can be used to support the wear-resistant plate 6. By changing the length of the adjusting bolt 9 extending into the rear cover 5, the distance between the wear-resistant plate 6 and the blanking plate 4 can be changed.

[0029] An intercepting assembly 7 is provided on the wear-resistant plate 6. The upper part of the intercepting assembly 7 passes through the wear-resistant plate 6 and extends into the feed hopper 3. The intercepting assembly 7 is used to intercept the aluminum ash slag falling from the outlet of the raw material bin 1. When the wear-resistant plate 6 moves up and down in the rear cover 5, the intercepting assembly 7 will move along with it, and thus the length of the intercepting assembly 7 extending into the feed hopper 3 can be changed.

[0030] In order to achieve comprehensive interception of the aluminum ash slag, the intercepting assembly 7 includes multiple rows of intercepting plates 71 arranged up and down. The number of intercepting plates 71 in each row is multiple and arranged at intervals. Thus, several intercepting plates 71 are distributed on the upper surface of the blanking plate 4. The intercepting plate 71 is perpendicular to the wear-resistant plate 6, and the intercepting plate 71 passes upward through the blanking plate 4, that is, holes are provided on the blanking plate 4 for the intercepting plate 71 to pass through.

[0031] Under the interception of several intercepting plates 71, an aluminum ash slag layer 10 is accumulated between several intercepting plates 71. The aluminum ash slag layer 10 is a layer structure with a certain thickness formed by the aluminum ash slag intercepted by several intercepting plates 71 and accumulated on the upper surface of the blanking plate 4. Thus, the aluminum ash slag layer 10 covers the upper surface of the blanking plate 4, which can protect the blanking plate 4 and prevent it from being worn.

[0032] In order to ensure the interception effect and reduce the fluidity of the aluminum ash slag layer 10, two adjacent rows of intercepting plates 71 are arranged in a vertical offset manner. At the same time, each intercepting plate 71 is bent into a "∨" shape, and the tip of the intercepting plate 71 faces the flowing direction of the aluminum ash slag. Thus, the intercepting plate 71 can intercept the aluminum ash slag better and ensure that the aluminum ash slag layer 10 can always exist.

[0033] When the utility model is manufactured: First, holes are opened on the blanking plate 4, and then it is installed on the feed hopper 3 and connected into an integral structure. Then, the wear-resistant plate 6 is prepared, and the intercepting plate 71 is provided on the wear-resistant plate 6. The intercepting plate 71 is inserted through the holes on the blanking plate 4 so that the upper part of the intercepting plate 71 extends into the feed hopper 3. Finally, the rear cover 5 is installed on the feed hopper 3. At this time, the wear-resistant plate 6 is placed in the rear cover 5. After the rear cover 5 is installed, the adjusting bolt 9 is rotated to realize the support and fixation of the wear-resistant plate 6.

[0034] The principle of the present utility model is as follows: after the aluminum ash slag in the raw material bin 1 falls, it will impact the blanking plate 4. Under the interception of a plurality of intercepting plates 71, the aluminum ash slag gradually accumulates between the plurality of intercepting plates 71 and gradually forms an aluminum ash slag layer 10 with a certain thickness. After the formation of the aluminum ash slag layer 10, there is no relative movement with the blanking plate 4, and the falling aluminum ash slag will impact the aluminum ash slag layer 10 and no longer impact and rub the blanking plate 4, thereby realizing the protection of the blanking plate 4 and achieving anti-wear of aluminum ash blanking.

[0035] After the intercepting plate 71 is used for a long time, wear may occur at its top end, which may cause the thickness of the aluminum ash slag layer 10 to decrease and the protection effect on the blanking plate 4 to weaken. To avoid the above situation, the adjusting bolt 9 can be rotated to make the anti-wear plate 6 closer to the blanking plate 4, and then the intercepting plate 71 also extends further into the feed hopper 3 to prevent the thickness of the aluminum ash slag layer 10 from decreasing and always effectively protect the blanking plate 4. The present utility model can greatly extend the service time of the blanking plate 4, there is no shutdown for maintenance, no leakage of aluminum ash slag, and the production efficiency and production continuity are improved.

[0036] The above-described embodiments are only the preferred embodiments of the present utility model and do not limit the scope of implementation of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present utility model patent shall be included in the scope of the patent application of the present utility model.
