Description

Technical Field

[0001] This utility model relates to the field of sintering equipment technology, specifically to a steel silo material collection structure. Background Technology

[0002] When the sintering batching chamber's unloading platform is in operation, heavy-duty mobile unloading cars drop the mixed materials into different ore bins. Because the ore bins are cylindrical and the mobile unloading cars deliver material continuously, some material accumulates in the gaps between the bins, preventing it from falling into the ore bins. This accumulated material rubs against the rotating conveyor belt, causing belt deformation and wear.

[0003] Currently, a common practice is to install a concrete ramp between the two ore bins, allowing materials to fall into the ore bins along the ramp. Figure 1 As shown. However, this structure has some shortcomings, such as: 1) because the inclination angle of the concrete inclined plate is small, the material cannot slide into the ore bin on its own, which can easily cause blockage; 2) if the worn inclined plate embedded parts are replaced, it may cause damage to the concrete inclined plate, making the construction more complicated.

[0004] In summary, there is an urgent need for a steel silo material collection structure to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this utility model is to provide a steel silo material collection structure, which aims to solve the problems of easy material blockage and complex subsequent maintenance and construction caused by setting a concrete inclined plate in the gap between two silos in the existing technology. The specific technical solution is as follows:

[0006] A steel silo material collection structure includes a steel silo and a chute. The chute is disposed on a material discharge platform. The wall of the steel silo near the material discharge platform is provided with a receiving chute, which connects to the interior of the steel silo. The discharge port of the chute overlaps with the receiving port of the receiving chute.

[0007] Preferably, from top to bottom, the distance D from the working surface of the receiving chute to the central axis of the steel silo gradually decreases; the working surface of the receiving chute is parallel to the length direction of the discharge platform at the receiving port, and the working surface of the receiving chute has the same curvature as the outer wall of the steel silo at the discharge port.

[0008] Preferably, the outer circumferential wall of the steel silo is provided with a non-complete annular steel silo stiffening rib, and the outer wall of the receiving chute is provided with a chute stiffening rib. The non-complete annular steel silo stiffening rib and the chute stiffening rib are set at the same height and are connected to each other by a connector.

[0009] Preferably, a plurality of first reinforcing plates are provided between the chute stiffening rib and the outer wall of the receiving chute, and a plurality of third reinforcing plates are provided between the non-completely annular steel bin stiffening rib and the outer wall of the steel bin along the circumferential direction.

[0010] Preferably, the circumferential outer wall of the steel silo is provided with a complete annular steel silo stiffening rib at the discharge port of the receiving chute, and a plurality of second reinforcing plates are provided circumferentially between the complete annular steel silo stiffening rib and the outer wall of the receiving chute, and a plurality of third reinforcing plates are provided circumferentially between the complete annular steel silo stiffening rib and the outer wall of the steel silo.

[0011] Preferably, the receiving chute is provided with a tensioning member at the receiving port, and the two ends of the tensioning member are respectively connected to the two side plates of the receiving chute.

[0012] Preferably, the tensioning component includes a screw and a protective sleeve. The two ends of the screw are respectively connected to the two side plates of the receiving chute, and the protective sleeve is sleeved on the screw and located between the two side plates.

[0013] Preferably, the working surface of the chute is provided with a buffer pad at the discharge port.

[0014] Preferably, a plurality of stiffening plates are provided at vertical intervals between the receiving chute and the outer wall of the steel silo.

[0015] Preferably, the steel bin is provided with at least two receiving chutes along the length of the unloading platform on the side near the unloading platform, and the unloading platform is provided with a corresponding number of chutes, the chutes and the receiving chutes are connected one-to-one.

[0016] The application of the technical solution of this utility model has the following beneficial effects:

[0017] In this invention, the receiving chute adopts an eccentric design. Specifically, from top to bottom, the distance D from the working surface of the receiving chute to the central axis of the steel silo gradually decreases. The working surface of the receiving chute is parallel to the length direction of the unloading platform at the receiving port, and has the same curvature as the outer wall of the steel silo at the discharge port. This eccentric design allows the width direction of the receiving port to be parallel to the length direction of the unloading platform. With the width directions of the receiving port and the chute parallel to the length direction of the unloading platform, there are no clearances between the chute, the unloading platform, or the receiving chute. Furthermore, the unloading platform does not require structural changes due to the addition of the receiving chute to the annular steel silo, thus not hindering the concrete construction of the unloading platform. Additionally, the receiving chute can be prefabricated in the factory, ensuring construction quality and shortening the construction period.

[0018] In this invention, the overlapping arrangement between the receiving chute and the feed chute allows the steel bin to be relatively separated from the unloading platform, ensuring the independence of the steel bin. At the same time, a tensioning member is provided at the receiving port of the receiving chute to prevent the two side plates of the receiving chute from deforming due to material impact. This also ensures that the circumferential structural stability of the steel bin does not deteriorate due to the addition of the receiving chute, thus achieving the effect of stabilizing the bin wall.

[0019] This utility model uses a receiving chute and a slide to guide materials into the interior of the steel bin. The design of the receiving chute and slide is no longer restricted by the angle between the discharge platform and the steel bin. The materials can slide into the steel bin autonomously and will not accumulate on the discharge platform.

[0020] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0029] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Example:

[0032] See Figures 2-6 This embodiment provides a steel silo material collection structure, including a steel silo 1 and a chute 3. The chute 3 is disposed on a material discharge platform 2. The wall of the steel silo 1 near the material discharge platform 2 is provided with a receiving chute 4. The receiving chute 4 connects to the interior of the steel silo 1. The discharge port of the chute 3 overlaps with the receiving port of the receiving chute 4, that is, the material enters the receiving chute 4 through the chute 3 and then enters the steel silo 1 through the receiving chute 4.

[0033] Furthermore, the receiving chute 4 includes a working base plate and two side plates 4.2. The two side plates are located on both sides of the working base plate, and the three form a U-shaped structure. The steel bin 1 has a vertical notch. The two side plates 4.2 are respectively connected to the steel bin walls on both sides of the notch. The discharge end of the working base plate is also connected to the steel bin wall at the bottom of the notch, thereby connecting the receiving chute to the steel bin. The side of the working base plate facing the inside of the steel bin is the working surface 4.1. In order to ensure that the width direction of the receiving port of the receiving chute 4 is parallel to the length direction of the unloading platform 2, the receiving chute 4 is eccentrically designed in this embodiment. Specifically, from top to bottom, the distance D from the working surface 4.1 of the receiving chute 4 to the central axis of the steel bin 1 gradually decreases. The working surface 4.1 of the receiving chute 4 is parallel to the length direction of the unloading platform 2 at the receiving port, and the working surface 4.1 of the receiving chute 4 has the same curvature as the outer wall of the steel bin 1 at the discharge port. This allows the width direction of the receiving port of the receiving chute 4 to be parallel to the length direction of the unloading platform 2. By setting the width direction of the receiving port of the receiving chute 4 and the width direction of the chute 3 to be parallel to the length direction of the unloading platform 2, the material can be guided to fall into the steel bin. At the same time, there is no gap between the chute and the unloading platform and the receiving chute 4, and the unloading platform does not need to be structurally modified because the receiving chute 4 is added to the annular steel bin.

[0034] See Figures 3-6The outer circumferential wall of the steel silo 1 is provided with a non-complete annular steel silo stiffening rib 5, and the outer wall of the receiving chute 4 is provided with a chute stiffening rib 6. The non-complete annular steel silo stiffening rib 5 and the chute stiffening rib 6 are set at the same height and connected to each other by a connector 7. The non-complete annular steel silo stiffening rib 5 and the chute stiffening rib 6 strengthen the circumferential structure of the steel silo and the receiving chute 4, preventing deformation of the steel silo 1 and the receiving chute 4 due to the impact of falling material. Furthermore, the strengthening structure composed of the non-complete annular steel silo stiffening rib 5 and the chute stiffening rib 6 can be arranged in multiple sets at intervals along the height direction to fully prevent deformation of the receiving chute 4 due to material impact.

[0035] Furthermore, multiple first reinforcing plates 8 are spaced apart between the chute stiffening rib 6 and the outer wall of the receiving chute 4, and multiple third reinforcing plates 11 are spaced apart circumferentially between the non-completely annular steel bin stiffening rib 5 and the outer wall of the steel bin 1. The third reinforcing plates 11 can increase the connection strength between the outer wall of the steel bin and the non-completely annular steel bin stiffening rib 5, and the first reinforcing plates 8 can increase the connection strength between the receiving chute 4 and the chute stiffening rib 6. Furthermore, the first reinforcing plates 8 can be provided between the chute stiffening rib and the side plate and working base plate of the receiving chute, or they can be spaced apart only between the chute stiffening rib and the working base plate of the receiving chute 4. Since the material mainly slides into the interior of the steel bin through the working surface of the working base plate, the working base plate needs to withstand greater impact force. Therefore, the first reinforcing plates 8 must be provided between the chute stiffening rib and the working base plate for structural reinforcement.

[0036] See Figures 3-6 The outer circumferential wall of the steel silo 1 is provided with a complete annular steel silo stiffening rib 5 at the discharge port of the receiving chute 4. Multiple second reinforcing plates 9 are spaced circumferentially between the complete annular steel silo stiffening rib 5 and the outer wall of the receiving chute 4 (specifically, the outer wall of the working base plate). Multiple third reinforcing plates 11 are also spaced circumferentially between the complete annular steel silo stiffening rib 5 and the outer wall of the steel silo 1. The complete annular steel silo stiffening rib 5 provides structural reinforcement to the steel silo wall. The second reinforcing plates 9 placed between the complete annular steel silo stiffening rib 5 and the outer wall of the receiving chute 4 at the discharge port provide structural reinforcement to the working base plate at the discharge port. It should be noted that the steel silo 1 can also be equipped with complete annular steel silo stiffening ribs 5 and second reinforcing plates 11 at locations where the receiving chute 4 is not located, to ensure the structural strength of the portion of the steel silo 1 without the receiving chute 4.

[0037] See Figure 5 and Figure 6The receiving chute 4 is equipped with a tensioning member 12 at the receiving inlet. The two ends of the tensioning member 12 are respectively connected to the two side plates 4.2 of the receiving chute 4. Specifically, the tensioning member 12 includes a screw and a protective sleeve. The two ends of the screw are respectively connected to the two side plates 4.2 of the receiving chute 4, and the protective sleeve is fitted onto the screw and located between the two side plates 4.2. The tensioning member 12 provides a tension force at the receiving inlet of the receiving chute 4, preventing the two side plates 4.2 of the receiving chute from deforming due to material impact. Simultaneously, it ensures that the circumferential structural stability of the steel silo does not deteriorate due to the addition of the receiving chute, thus effectively stabilizing the silo wall. Preferably, in this embodiment, the tensioning member is detachable for easy maintenance and replacement later.

[0038] See Figure 3 In this embodiment, the working surface of the chute 3 is provided with a buffer pad 3.1 at the discharge port. The buffer pad 3.1 can buffer the falling material at the chute discharge port, reducing the impact of the falling material on the receiving chute 4. At the same time, it can also prevent material leakage at the junction of the chute and the receiving chute. Preferably, the buffer pad is installed on the working surface of the chute in a detachable manner, which facilitates the maintenance and replacement of the buffer pad in the future. Specifically, the working surface of the chute refers to the side of the chute facing the inside of the steel bin and used to receive the falling material.

[0039] See Figures 3-6 Multiple stiffening plates 10 are provided vertically between the receiving chute 4 and the outer wall of the steel silo 1. Specifically, multiple stiffening plates 10 are provided vertically between the outer wall of the side plate 4.2 of the receiving chute 4 and the outer wall of the steel silo 1, thereby increasing the structural strength of the connection between the receiving chute 4 and the steel silo 1.

[0040] like Figure 2 As shown, the steel bin 1 is provided with at least two receiving chutes 4 along the length of the unloading platform 2 on the side near the unloading platform 2. The unloading platform 2 is provided with a corresponding number of chutes 3. The chutes 3 and the receiving chutes 4 are connected one-to-one. By adding receiving chutes 4 and chutes 3, the number of receiving points of the steel bin can be increased, and the receiving efficiency can be improved.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
