Description

Technical Field

[0001] The utility model relates to the technical field of material storage, in particular to a silo with a material segregation prevention function. Background Art

[0002] In the electrolytic aluminum production process, alumina particle size segregation affects the electrolytic cell production process, attracting more and more attention and research from the aluminum industry at home and abroad. With the application of large-scale electrolytic cells and advanced cell control machines, the control of alumina concentration and feeding time has become more stringent, so maintaining good material uniformity and balance is particularly important.

[0003] The quality of alumina and its storage and transportation methods are the main factors leading to alumina particle size segregation. Without considering the difference in alumina quality, reasonable storage and transportation methods and proper control measures can greatly reduce the breakage rate and particle size segregation of alumina. However, at present, the silos of most factories still have the problem of particle size segregation. Research has found that after alumina enters the silo, due to the action of gravity, large particles of alumina fall to the bottom of the silo quickly, while fine alumina particles float in the silo for a long time and eventually fall on the surface of large particles of alumina. This uneven distribution causes the size of alumina particles flowing out of the silo to change over time, which in turn has an adverse effect on the production quality of the electrolytic cell.

[0004] Therefore, it is urgent to design a silo with material anti-segregation function to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings in the prior art, the purpose of the present invention is to provide a silo with a material segregation prevention function.

[0006] The technical solution is: a silo with material anti-segregation function, including a base, a main body, a discharge valve pipe and a silo cover. The upper part of the base is fixedly connected to the main body, the bottom of the main body is provided with a discharge valve pipe, the top of the main body is provided with a silo cover, and also includes an anti-segregation component. Multiple anti-segregation components are arranged at intervals on the inner wall of the main body. The anti-segregation components are used to guide the material that is about to enter the main body.

[0007] As a further preferred solution, the anti-segregation component includes a fixed bracket, a material guide tube, a lifting ring, a rotating shaft and a baffle. Since the multiple anti-segregation components arranged on the inner wall of the main body are the same, one of the anti-segregation components is taken as an example for description. A plurality of pairs of fixed brackets are fixedly connected on the inner wall of the main body from top to top in an interval manner. A material guide tube is fixedly connected between these fixed brackets. A plurality of square openings are provided on the side of the material guide tube facing the center of the main body from top to bottom in an interval manner. A pair of lifting rings are fixedly connected on the side wall of the material guide tube near the square openings. A rotating shaft is rotatably connected between the same pair of lifting rings. A baffle is fixedly connected to the rotating shaft. The baffle can cover the adjacent square openings. A plurality of reserved holes are provided on the bin cover corresponding to the material guide tube.

[0008] As a further preferred solution, the number of anti-segregation components is 3-10.

[0009] As a further preferred solution, it also includes weight-increasing strips, and the lower sides of the baffles are fixedly connected with weight-increasing strips.

[0010] As a further preferred solution, a sealing plate and a fixing rod are also included. The sealing plate is movably provided on the top of the material guide tube, and two fixing rods are fixedly connected to the top of the sealing plate at intervals.

[0011] As a further preferred solution, it also includes connecting ropes and magnetic balls. Two connecting ropes are fixedly connected to the top of the guide plate at intervals. The two connecting ropes pass through adjacent fixed rods respectively, and the movable ends of the connecting ropes are fixedly connected to the magnetic balls.

[0012] The utility model has the following advantages: the material is directly injected into the bottom of the main body through the guide pipe, which effectively avoids the segregation problem of the material caused by the excessive drop height; the material forms a conical distribution at the bottom of the guide pipe; as the material is continuously injected, the baffles are pushed open in sequence, and the material flows out from the square opening from bottom to top, maintaining a low drop height, further reducing the risk of segregation, thus ensuring that the material is evenly distributed inside the silo, effectively avoiding the occurrence of segregation, and improving the efficiency and quality of material storage and use.

DETAILED DESCRIPTION

[0018] The following further illustrates the technical solution with reference to specific embodiments. It should be noted that terms such as "up," "down," "left," and "right" used herein to indicate directions refer only to the positions of the structures depicted in the corresponding drawings. Component numbers, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connected" and "coupled" in this application, unless otherwise specified, include both direct and indirect connections (couplings).

[0019] Example: A silo with a material segregation prevention function, such as Figure 1-Figure 4 As shown, it includes a base 1, a main body 2, a discharge valve pipe 3 and a bin cover 4. The main body 2 is welded and fixed on the upper part of the base 1. The main body 2 is a cylinder with an opening at the top. The bottom of the main body 2 is provided with a discharge valve pipe 3 for discharging the material inside it. The top of the main body 2 is fixed with a bin cover 4 by bolts. It also includes an anti-segregation component. A plurality of anti-segregation components are arranged at intervals on the inner wall of the main body 2. The anti-segregation component is used to guide the material that is about to enter the inside of the main body 2.

[0020] like Figure 2 and Figure 3 As shown, the anti-segregation assembly includes a fixed bracket 5, a guide tube 6, a lifting ring 9, a rotating shaft 10 and a baffle 11. Since the multiple anti-segregation assemblies provided on the inner wall of the main body 2 are the same, one of the anti-segregation assemblies is described as an example. A plurality of pairs of fixed brackets 5 are welded and fixed to the inner wall of the main body 2 from top to bottom. The fixed brackets 5 are fixed together with the guide tube 6 by bolts. The guide tube 6 is a square shell that passes through from top to bottom. A plurality of square openings 8 are provided on the side of the guide tube 6 toward the center of the main body 2 from top to bottom. A pair of lifting rings 9 are welded and fixed near the square openings 8 on the side wall of the guide tube 6. The rings 9 are rotatably connected with a rotating shaft 10, and a baffle 11 is welded and fixed on the rotating shaft 10. In the natural state, the baffle 11 can cover the adjacent square openings 8. A plurality of reserved holes 7 are provided on the bin cover 4 corresponding to the guide tube 6. The reserved holes 7 are used for the upper end of the guide tube 6 to pass through when the bin cover 4 is fixed to the top of the main body 2. The number of anti-segregation components is 3-10. The standard configuration is to set three anti-segregation components on the inner wall of the main body 2. When it is necessary to speed up the speed at which the material fills the internal space of the main body 2, the number of anti-segregation components set on the inner wall of the main body 2 can be increased, and the maximum number shall not exceed 10.

[0021] When it is necessary to inject material into the main body 2, the staff uses the material pumping device configured near the base 1 to inject the material from the top of the guide tube 6. The material will first pass through the guide tube 6 directly to the bottom of the main body 2, which effectively avoids the segregation problem that may be caused by the excessive drop height of the material when the material is injected at the top of the main body 2. After the material flows out from the bottom of the guide tube 6, it will gradually form a cone-shaped distribution inside the main body 2. When the material at the top of the cone accumulates to a certain extent and blocks the lower end of the guide tube 6, as the material is continuously injected, the material inside the guide tube 6 is high. The degree of the material will gradually rise until it exceeds the lowest baffle 11. At this time, the material will push the baffle 11 to flip outward due to its own weight, thereby opening the lowest square opening 8, and the material will continue to flow out from here. Since the height of the material inside the main body 2 is almost the same as the height of the square opening 8 at this time, the drop height of the material after flowing out of the square opening 8 is not large, which further reduces the risk of material segregation. As the material is continuously injected, the material will flow out from each square opening 8 in turn from bottom to top, thereby effectively avoiding the segregation of the material inside the silo.

[0022] like Figure 3 As shown, it also includes a weight-increasing strip 12 , and the weight-increasing strip 12 is welded and fixed to the lower side of the baffle 11 .

[0023] The weighted strips 12 are provided to increase the stability of the baffle 11 and effectively prevent the baffle 11 from accidentally flipping over due to the airflow generated by the material falling from the material guide pipe 6, thereby preventing the material from being blown out from the square opening 8 and causing segregation problems.

[0024] like Figure 4 As shown, it also includes a sealing plate 13 and a fixing rod 14. The sealing plate 13 is movably provided on the top of the guide tube 6. The sealing plate 13 can close the upper end of the guide tube 6. Two fixing rods 14 are fixedly connected to the top of the sealing plate 13 at intervals. The two fixing rods 14 are in contact with the top of the guide tube 6, so that the sealing plate 13 can be maintained at the position at the upper end of the guide tube 6.

[0025] By setting the sealing plate 13 and the fixing rod 14 , after the material is injected into the material guide tube 6 , the staff will clamp the sealing plate 13 into the top of the material guide plate to seal the top of the material guide tube 6 to prevent impurities in the air from entering the material guide tube 6 .

[0026] like Figure 4 As shown, it also includes a connecting rope 15 and a magnetic ball 16. Two connecting ropes 15 are fixedly connected to the top of the guide plate at intervals. The two connecting ropes 15 respectively pass through adjacent fixed rods 14. The movable ends of the connecting ropes 15 are fixedly connected to the magnetic balls 16.

[0027] By setting the connecting rope 15 and the magnetic ball 16, when it is necessary to inject material into the material guide tube 6, the staff will remove the sealing plate 13, and the connecting rope 15 can prevent the sealing plate 13 from falling from the top of the bin cover 4. After the material is injected, the staff will reset the sealing plate 13 and use the magnetic ball 16 to magnetically fix it to the top of the sealing plate 13, so as to effectively prevent the connecting rope 15 from swinging at will.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
