Description

Technical Field

[0001] The utility model relates to the technical field of silos, in particular to an impact-resistant and wear-resistant silo. Background Art

[0002] The steel industry uses silos for storage and batching of materials during production. Silos are often used for storage and batching. Materials are loaded into the silos by belts or buckets, where they are weighed before entering the furnace. Existing silos are typically constructed from welded steel plates, with some silos lined with ceramic or wear-resistant linings. These silos have a rectangular upper section and a conical lower section that connects to the feed pipe.

[0003] Silos are often impacted by falling raw materials. This impact on the silo's inner walls can damage certain areas, necessitating frequent repairs with steel plates. If leaks go undetected, production quality is compromised. Equipment downtime caused by silo leaks can also impact production schedules. Silos are often replaced during annual overhauls, resulting in significant costs. Utility Model Content

[0004] In response to the technical problems existing in the prior art, the purpose of the utility model is to provide an impact-resistant and wear-resistant silo. When the raw materials fall, they impact the raw materials retained in the cone bucket, thereby reducing the probability of the silo side wall being impacted by the raw materials and extending the life of the silo.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A silo that is impact-resistant and wear-resistant includes a conical hopper plate. Multiple conical hopper plates are fixedly connected to the inner wall of the silo. Each conical hopper plate forms a conical hopper with an upward opening and a closed bottom with the inner wall of the silo. Multiple conical hoppers are arranged in rows from top to bottom, and the multiple rows of conical hoppers are evenly distributed circumferentially in the silo. No lining plate is provided on the inner wall of the silo.

[0007] As a preferred embodiment, the cone hopper plate includes an inclined plate and a vertical plate, the inclined plate is fixedly connected to the inner side wall of the silo, the inclined plate and the vertical plate are fixedly connected, and the inclined plate and the vertical plate form an obtuse angle.

[0008] As a preferred embodiment, the vertical board is perpendicular to the horizontal plane.

[0009] As a preferred embodiment, the angle formed by the inclined plate and the vertical plate is 135 degrees.

[0010] As a preferred embodiment, the width ratio of the inclined plate to the vertical plate is 3:1, and the length of the inclined plate is the same as that of the vertical plate.

[0011] As a preferred embodiment, the inclined plate and the vertical plate are welded into one body or the inclined plate and the vertical plate are pressed from a whole plate.

[0012] As a preferred embodiment, the main body and cone bucket plate of the silo are both made of steel plates with a thickness of 10 mm.

[0013] As a preferred embodiment, the silo includes an upper silo and a lower silo. The upper silo has a cylindrical structure, and the lower silo has a conical structure. The upper silo is connected to the lower silo. The upper part of the upper silo is an open feed port, and the bottom of the lower silo is provided with a discharge port equipped with a discharge valve.

[0014] As a preferred embodiment, the upper hopper includes four rectangular side panels, and the side edges of the four rectangular side panels are circumferentially fixedly connected in sequence to form a cuboid; the lower hopper includes four isosceles trapezoidal side panels, and the side edges of the four isosceles trapezoidal side panels are circumferentially fixedly connected in sequence to form a funnel shape, the lower edge of the rectangular side panel is the same length as the upper base edge of the isosceles trapezoidal side panel, and the lower edge of each rectangular side panel is fixedly connected to the upper base edge of the corresponding trapezoidal side panel below.

[0015] As a preferred embodiment, the angle formed by the inclined plate of the cone bucket plate and the rectangular side plate is 45 degrees, the angle formed by the inclined plate and the isosceles trapezoidal side plate is 90 degrees, and the vertical plate is perpendicular to the horizontal plane.

[0017] The utility model has the following advantages:

[0018] 1. The utility model does not provide a lining plate in the silo. A cone hopper is formed by providing a cone hopper plate on the inner wall of the silo. When the raw materials fall to the inner wall of the silo, a part of the raw materials will be retained in the cone hopper. When the raw materials fall again, they will impact the raw materials retained in the cone hopper, minimizing the probability of direct impact on the inner wall of the silo, thereby making the inner wall of the silo resistant to impact and wear, and not easily damaged, thereby increasing the service life of the silo, reducing the probability of equipment shutdown due to silo leakage, and ensuring stable production; the manufacturing method of the cone hopper is simple, which is conducive to promotion.

[0019] 2. The vertical plate is perpendicular to the horizontal plane, which makes the cone bucket have a larger capacity and retains more raw materials.

[0020] 3. Both the silo and the cone hopper plate are made of 10mm thick steel plates, which are thinner than the 20mm steel plates generally used in the prior art. In addition, no lining plate is set in the silo of the utility model, which is lighter and easier to install, and also greatly reduces the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, an impact-resistant and wear-resistant silo is used to load any one of lime, sintered ore, pelletized ore, limestone, or high-magnesium raw materials, including a cone hopper plate 1. Multiple cone hopper plates 1 are welded on the inner wall of the silo. Each cone hopper plate 1 forms a cone hopper 2 with the inner wall of the silo, which is open upward and closed at the bottom. Multiple cone hoppers 2 are arranged in rows from top to bottom, and multiple rows of cone hoppers 2 are evenly distributed circumferentially in the silo; no lining is provided on the inner wall of the silo.

[0030] like Figure 2 、 Figure 3 As shown, the cone hopper plate 1 includes an inclined plate 3 and a vertical plate 4. The inclined plate 3 is fixedly connected to the inner wall of the silo, and the inclined plate 3 and the vertical plate 4 are fixedly connected. The inclined plate 3 and the vertical plate 4 form an obtuse angle. In this embodiment, the angle formed by the inclined plate 3 and the vertical plate 4 is preferably 135 degrees; the vertical plate 4 is perpendicular to the horizontal plane.

[0031] like Figure 2 As shown, a is the width of the inclined plate 3, b is the width of the vertical plate 4, and the ratio of a to b is 3:1. Figure 3 As shown, the inclined plate 3 and the vertical plate 4 have the same length.

[0032] The inclined plate 3 and the vertical plate 4 are welded into one body or the inclined plate 3 and the vertical plate 4 are formed by pressing a whole plate.

[0033] The main body of the silo and the cone hopper plate 1 are both made of steel plates with a thickness of 10 mm.

[0034] like Figure 1 、 Figure 4 As shown, the silo includes an upper silo 5 and a lower silo 6. The upper silo 5 is a cylindrical structure, and the lower silo 6 is a conical structure. An external supporting device 8 is welded to the outside of the lower silo 6. The upper silo 5 and the lower silo 6 are connected. The upper part of the upper silo 5 is an open feed port, and the bottom of the lower silo 6 is provided with a discharge port equipped with a discharge valve, and a discharge valve mounting seat 9 is welded at the discharge port.

[0035] The upper hopper 5 includes four rectangular side panels, and the side edges of the four rectangular side panels are fixedly connected in sequence in a circumferential direction to form a cuboid; the lower hopper 6 includes four isosceles trapezoidal side panels, and the side edges of the four isosceles trapezoidal side panels are fixedly connected in sequence in a circumferential direction to form a funnel shape, and the lower edge of the rectangular side panel is the same length as the upper base edge of the isosceles trapezoidal side panel, and the lower edge of each rectangular side panel is fixedly connected to the upper base edge of the corresponding trapezoidal side panel below.

[0036] In this embodiment, the angle formed between the inclined plate 3 of the cone bucket plate 1 and the rectangular side plate is preferably 45 degrees, and the angle formed between the inclined plate 3 and the isosceles trapezoidal side plate is preferably 90 degrees.

[0037] The working principle of the silo: the feeding pipe 7 for feeding materials into the silo is located obliquely above the silo. When the materials are first dropped, the raw materials will fall into the cone hopper 2 formed by the inner wall of the silo and the cone hopper plate 1. A part of the raw materials will always be retained in the cone hopper 2. The raw materials dropped again will impact the raw materials retained in the cone hopper 2, thereby reducing the probability of the inner wall of the silo being directly impacted by the raw materials. Therefore, the silo of the utility model has the effect of wear resistance and impact resistance.

[0038] The silo of the prior art generally has a lifespan of 1 year, and after repeated repairs, it may be used for 2 years; however, the silo of the utility model is made of 10 mm thick steel plate, and the cone bucket 2 protects the inner wall of the silo from damage. From the current test results, it is speculated that the silo of the utility model can be used for more than 5 years.

[0039] In addition to the above embodiments, the silo can be cylindrical in shape, which can be a rectangular parallelepiped, a cube, an inverted truncated cone, or a cylinder; or the upper silo 5 can be cylindrical and the lower silo 6 can be conical, with the diameters of the connection between the upper silo 5 and the lower silo 6 being the same. These variations are all within the scope of protection of the present invention.

[0040] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
