Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ash processing equipment, in particular to a pipeline steering device. Background Art

[0002] Aluminum ash treatment mostly uses high-pressure air generated by Roots blowers to transport the generated aluminum ash to the ash bin through pipes. Due to the large area of ​​aluminum production equipment and terrain reasons, the transportation of aluminum ash cannot be completed through a straight pipe. At this time, the aluminum ash transportation pipeline will have multiple turns (such as elbows). When equipment fails during the transportation of aluminum ash, aluminum ash will be deposited in the pipeline. Multiple turns will make the pipeline difficult to repair.

[0003] When high-pressure air drives aluminum ash to move, it will impact the turning part of the pipe, causing a large grinding effect and causing serious wear of the pipe. Currently, after about three months of use, the newly installed pipe will cause aluminum ash leakage due to wear and tear. At this time, the pipe needs to be repaired, which reduces production efficiency and increases production costs. Summary of the invention

[0004] In order to solve the problems that aluminum ash is deposited in the pipeline, multiple turns make the pipeline difficult to maintain, and high-pressure air impacts the turns of the pipeline, causing serious wear of the pipeline and affecting production efficiency, the utility model proposes a pipeline steering device. Through the detachable connection between the upper cover and the box body, the turns of the pipeline can be cleaned when aluminum ash is deposited in the pipeline, and maintenance is more convenient. At the same time, the box body arranged between the first conveying pipe and the second conveying pipe allows the high-pressure air to drive the movement of aluminum ash and impact on the side wall of the box body, thereby reducing pipeline wear, realizing long-term use of the aluminum ash conveying pipeline, and improving production efficiency.

[0005] In order to achieve the above purpose, the technical solution of the utility model is: a pipeline steering device, including a first delivery pipe, a second delivery pipe and a hollow box connecting the first delivery pipe and the second delivery pipe, the ends of the first delivery pipe and the second delivery pipe are connected to the box, and the upper cover of the box is detachably connected to the box. The high-pressure air blown by the fan drives the aluminum ash from the first delivery pipe to the second delivery pipe, and the box connected between the first delivery pipe and the second delivery pipe can alleviate the grinding of the pipeline caused by the high-pressure air driving the aluminum ash, and at the same time reduce the wear of the aluminum ash, thereby improving the production efficiency.

[0006] Furthermore, the upper cover is fixedly connected to the upper end surface of the box body by bolts, and a sealing rubber pad is arranged between the upper cover and the box body. During the long-term transportation of aluminum ash, the pipeline is seriously worn or even punctured, and the aluminum ash leaks directly from the punctured part. At this time, the pipeline needs to be repaired, and the aluminum ash in the straight part of the pipeline is easy to remove, while the aluminum ash at the bend is not easy to remove. At this time, the flange can be loosened, the upper cover can be removed, and the pipeline can be cleared in sections.

[0007] Furthermore, the box body is cylindrical, truncated cone or prism-shaped.

[0008] Furthermore, the inner diameters of the first delivery pipe and the second delivery pipe are the same.

[0009] Furthermore, a protective plate is provided on the bottom plate of the box, and an opening is provided on the protective plate, and the opening matches the ends of the first delivery pipe and the second delivery pipe. The shape of the protective plate matches the shape of the box (for example, when the box is cylindrical, the protective plate is annular).

[0010] Furthermore, a placement groove is provided on the bottom plate, and the protective plate is placed in the placement groove and fits with the inner wall of the box. The protective plate is closely attached to the inner wall of the box to prevent the aluminum ash from directly impacting the side wall of the box. The protective plate placed in the placement groove will be worn under the impact of high-pressure air and aluminum ash for a long time. At this time, the upper cover on the box can be opened to replace the new protective plate. The replacement is quick and maintenance is convenient, which improves the efficiency of aluminum ash transportation.

[0011] Furthermore, there are multiple first delivery pipes. In actual production, in order to integrate the collecting end of the aluminum ash delivery pipeline, there will be a situation where multiple first delivery pipes are connected to one second delivery pipe through a box.

[0012] Through the above technical scheme, the beneficial effects of the utility model are as follows: the utility model connects the first conveying pipe and the second conveying pipe through a box body, and the box body replaces the elbow to alleviate the grinding of the pipeline caused by aluminum ash driven by high-pressure air, while reducing the wear of the pipeline and aluminum ash, thereby improving production efficiency. At the same time, the detachable connection between the upper cover and the box body can loosen the bolts when aluminum ash is deposited in the pipeline, and the upper cover can be removed from the box body to achieve segmented dredging of the pipeline, making maintenance more convenient. At the same time, a protective plate that is adapted to the shape of the box body is provided on the bottom plate of the box body, which can prevent aluminum ash from directly impacting the side wall of the box body, and the protective plate is placed in the placement groove. The upper cover on the box body can be opened to replace the new protective plate, thereby increasing the service life of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0019] Example 1

[0020] like Figure 1-Figure 3 As shown, this embodiment provides a pipeline steering device, including a first conveying pipe 1, a second conveying pipe 2 and a hollow box 3 connecting the first conveying pipe 1 and the second conveying pipe 2, the ends of the first conveying pipe 1 and the second conveying pipe 2 are both connected to the box 3, and the box 3 connected between the first conveying pipe 1 and the second conveying pipe 2 is used to alleviate the grinding of the pipeline caused by aluminum ash driven by high-pressure air.

[0021] The upper cover 4 of the box body 3 is detachably connected to the box body 3. In the present embodiment, the upper cover 4 is fixedly connected to the upper end surface of the box body 3 by bolts to achieve detachability. A sealing rubber pad is provided between the upper cover 4 and the box body 3. The upper cover 4 is removed from the box body 3 by loosening the bolts. At this time, the aluminum ash deposited at the turning point (i.e., in the box body 3) can be manually cleaned.

[0022] In order to prevent aluminum ash from directly impacting the side wall of the box body 3, a protective plate 5 is provided on the bottom plate of the box body 3. The protective plate 5 is provided with an opening, which matches the end of the first conveying pipe 1 and the second conveying pipe 2.

[0023] Specifically, a placement groove 7 is provided on the bottom plate of the box body 3, and the protective plate 5 is placed in the placement groove 7 and fits with the inner wall of the box body 3. The protective plate 5 placed in the placement groove 7 will be worn under the impact of high-pressure air and aluminum ash for a long time. At this time, the upper cover 4 on the box body 3 can be opened to replace the new protective plate 5, making the maintenance of the conveying pipeline more convenient and improving the efficiency of pipeline maintenance.

[0024] In this embodiment, the shapes of the protection plate 5 and the placement groove 7 match the shape of the box body 3, and the box body 3 is cylindrical, truncated cone or prism. Figure 2 and Figure 3As shown, when the box body 3 is cylindrical, the cross-sections of the protection plate 5 and the placement groove 7 are circular.

[0025] In this embodiment, the inner diameters of the first delivery pipe 1 and the second delivery pipe 2 are the same. When the box body 3 is cylindrical, the inner diameter of the box body 3 is 2-5 times the inner diameters of the first delivery pipe 1 and the second delivery pipe 2.

[0026] When in use, the first conveying pipe 1 and the second conveying pipe 2 are connected by a cylindrical hollow box 3. Driven by the high-pressure air of the fan, the aluminum ash enters the box 3 from the first conveying pipe 1 and then enters the second connecting pipe 2 from the box 3. During this process, the aluminum ash will continuously impact the side wall of the box 3. The box 3 with a protective plate 5 and the opening on the annular protective plate 5 make the box 3 and the first conveying pipe 1 and the second conveying pipe 2 so that the aluminum ash will directly impact the inner surface of the protective plate 5, thereby increasing the service life of the pipeline steering device.

[0027] Example 2

[0028] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that there are two first conveying pipes 1, and there are two openings on the protective plate 5 that match the end of the first conveying pipe 1. The reason for this arrangement is: in actual production, there will be a situation where multiple first conveying pipes 1 convey aluminum ash at the same time, and in order to integrate the collection end of the aluminum ash conveying pipeline, there will be a situation where multiple first conveying pipes 1 are connected to a second conveying pipe 2 through the box body 3.

[0029] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
