Abstract
Description
Technical Field
[0001] This utility model relates to the field of plate-shaped corundum processing, and in particular to a pipeline buffer device for plate-shaped corundum processing. Background Technology
[0002] Tabular corundum is a pure sintered corundum that undergoes complete shrinkage during firing without any additives. It has a coarse-grained, well-developed α-Al₂O₃ crystal structure with an Al₂O₃ content of over 99%, and possesses properties such as high temperature resistance, corrosion resistance, and high hardness. The typical production process involves grinding alumina into fine powder, adding water to form pellets, drying the raw wet pellets, and then calcining them in a vertical kiln. The calcined pellets undergo multiple crushing and grinding processes to prepare particles of different sizes, ranging from approximately 3 micrometers to approximately 20 millimeters.
[0003] During the processing stage, tabular corundum is frequently transported in the factory through pipelines. Due to its extremely high hardness, tabular corundum can cause wear and tear on the pipelines, especially at bends where it is subjected to the most severe impact and wear, requiring regular maintenance and replacement. Since the pipelines are generally made of iron, the iron filings scraped off can mix with the tabular corundum particles, thus affecting the purity of the tabular corundum and the product qualification rate. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a pipe buffer device for processing plate-shaped corundum, which is installed at the bend of the pipe to protect the pipe.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a pipeline buffer device for processing plate-shaped corundum, including a protective cover, a feed inlet, a discharge outlet, a buffer plate and a connecting rod; the top of the protective cover is provided with a feed inlet and the bottom of the protective cover is provided with a discharge outlet; the inside of the protective cover is provided with a buffer plate for receiving plate-shaped corundum, and the bottom end of the buffer plate is connected to the inner wall of the protective cover through the connecting rod.
[0006] The feed inlet is located in the central area of the top of the protective cover, and the feed inlet is inclined, with the feed inlet tilted away from the center point of the top of the protective cover. Designing the feed inlet as an inclined inlet is beneficial for connecting with the inclined pipe above, and designing the position of the feed inlet in the central area of the top of the protective cover is beneficial for the plate-shaped corundum to fall into the central area of the buffer plate.
[0007] The lower half of the protective cover is a funnel-shaped structure that is wider at the top and narrower at the bottom, and the discharge port is located at the bottom center of the funnel-shaped structure, which facilitates material discharge.
[0008] The buffer plate is a circular plate with a flat top surface, preferably made of steel plate, which has good wear resistance.
[0009] The beneficial effects of this utility model are as follows: The pipeline buffer device is installed at the bend of the pipeline. The plate-shaped alumina first falls from the inlet into the central area of the top surface of the buffer plate, and then accumulates on the buffer plate. During the accumulation process, some of the plate-shaped alumina will fall to the outlet after collision and be discharged, while most of the plate-shaped alumina will remain on the buffer plate to form a cone shape until the amount of accumulated alumina is greater than the angle of repose. At this point, the plate-shaped alumina will fall along the edge and be discharged from the outlet. When the plate-shaped alumina is continuously fed, the plate-shaped alumina falling from the inlet will first come into contact with the plate-shaped alumina remaining on the buffer plate, and will not directly impact the bend pipeline, which helps to reduce pipeline wear and extend service life.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0016] Reference Figure 1-2 This embodiment provides a pipeline buffer device for processing tabular corundum, including a protective cover 1, a feed inlet 2, a discharge outlet 3, a buffer plate 4, and connecting rods 5; the protective cover 1 has a feed inlet 2 at the top and a discharge outlet 3 at the bottom; the protective cover 1 has a buffer plate 4 inside for receiving tabular corundum, and the bottom end of the buffer plate 4 is connected to the inner wall of the protective cover 1 through two connecting rods.
[0017] In this embodiment, in order to adapt to the structure of the pipe bend and to ensure that the plate-shaped corundum falling from the inlet 2 lands as close as possible in the central area of the buffer plate 4, the inlet 2 is located in the area on one side of the top center of the protective cover 1, and the inlet 2 is tilted away from the top center point of the protective cover 1; this is beneficial for the connection between the inlet 2 and the bend, and also beneficial for the plate-shaped corundum to land in the central area of the top surface of the buffer plate 4.
[0018] In this embodiment, in order to facilitate the collection of plate-shaped corundum at the discharge port 3, the lower half of the protective cover 1 is a funnel-shaped structure that is wider at the top and narrower at the bottom, and the discharge port 3 is located at the bottom center of the funnel-shaped structure, thereby facilitating material discharge.
[0019] In this embodiment, in order to maintain a natural and stable state when the plate-shaped corundum is stacked on the buffer plate 4, the buffer plate is a circular plate with a flat top surface, and the material is preferably a steel plate with good wear resistance.
[0020] Reference Figure 3 This pipe buffer device for processing tabular alumina is installed at pipe bends. Tabular alumina enters the protective cover 1 through the inlet 2 and first falls onto the central area of the top surface of the buffer plate 4. It then accumulates on the buffer plate 4. During the accumulation process, some tabular alumina will fall to the outlet 3 after collision and be discharged, while most tabular alumina will remain on the buffer plate 4, forming a cone shape, until the amount of accumulated alumina exceeds the angle of repose (the angle of repose is the maximum angle at which bulk material can maintain a natural and stable state when stacked; this angle is the angle between the bulk material and the horizontal surface. When the bulk material is stacked to this angle, any further addition of such bulk material will naturally slide down). The tabular alumina will then fall along the edge of the buffer plate 4 and finally be discharged from the outlet 3. When tabular alumina is continuously fed, the tabular alumina falling from the inlet 2 first contacts the tabular alumina remaining on the buffer plate 4, thus offsetting the impact force.
[0021] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
