Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically a novel coke conveyor chute that effectively intercepts iron objects during coke transportation and reduces belt tearing failures. Background Technology

[0002] Large coking plants typically use belt conveyor technology for coke transport, which is economical and environmentally friendly. Currently, the belt speed is generally 2.5 m / s, with some units reaching speeds of 3 m / s in pursuit of efficiency. Our plant has long produced Grade 1 coke (M10:6.5, CSR:68). The coke transport process causes significant impact on equipment such as chutes, frequently resulting in wear and tear. Iron pieces worn off from the equipment pass through the magnetic separator at high speed with the coke. Some iron pieces buried beneath the coke are not adsorbed by the magnetic separator and enter the belt, posing a significant risk of belt damage. Belt failures not only cause production interruptions and huge economic losses but also pose significant fire and environmental risks. Our plant has approximately 2000 meters of ST1600 steel cord conveyor belt (1400mm wide) and 5500 meters of ST1000 steel cord tubular conveyor belt (350mm diameter), which are of considerable value; damage from iron pieces would result in substantial losses.

[0003] To address the aforementioned issues, a novel coke conveying chute has been proposed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coke conveying line chute, comprising a chute body, a first side plate, a second side plate, and a protective net.

[0006] The first side plate and the second side plate are respectively welded to both sides of the chute body along its length to form a space that can accommodate the protective net.

[0007] The protective netting includes a protective netting body and a wear-resistant layer.

[0008] The protective net body includes a fixing plate, a first receiving plate, and a second receiving plate, wherein:

[0009] The fixing plate is a rectangular frame, which is fixedly connected to the first side plate and the second side plate respectively. The fixing plate is used to fix the protective net between the first side plate and the second side plate.

[0010] The length direction of the first receiving plate is perpendicular to the length direction of the second receiving plate. Each of the first receiving plates and the second receiving plates is fixedly connected to a group in a uniform and staggered manner, and both ends of each of the first receiving plates and the second receiving plates are fixedly connected to the fixing plate, forming multiple grids of equal area.

[0011] The wear-resistant layer is fixedly connected to the surface of the protective net body.

[0012] Furthermore, the thickness of the protective net body is 150mm.

[0013] Furthermore, the fixing plate is welded to the first receiving plate, the fixing plate is welded to the second receiving plate, and the first receiving plate is welded to the second receiving plate; or, the fixing plate, the first receiving plate, and the second receiving plate are integrated into one piece.

[0014] Furthermore, the protective net body is made of Q345B low-alloy high-strength structural steel.

[0015] Furthermore, the size of the grid is 200mm × 200mm.

[0016] Furthermore, the wear-resistant layer is formed by welding DMD266 or DMD337 high manganese steel welding rods onto the protective net body.

[0017] Furthermore, the weld thickness of the DMD266 high-manganese steel welding electrode is 10mm.

[0018] Analysis shows that this utility model provides a novel coke conveying chute, including a chute body, a first side plate, a second side plate, and a protective net; the first side plate and the second side plate are respectively welded to both sides of the chute body along its length, forming a space capable of accommodating the protective net; the first side plate and the second side plate are used to prevent coke from falling outside the chute body during transportation; the protective net includes a protective net body and a wear-resistant layer; the protective net body includes a fixing plate, a first receiving plate, and a second receiving plate, wherein: the fixing plate is a rectangular frame, and the fixing plate is fixedly connected to the first side plate and the second side plate respectively, and the fixing plate is used to hold the protective net in place. The net is fixed between the first side plate and the second side plate; the length direction of the first receiving plate is perpendicular to the length direction of the second receiving plate, and each of the first and second receiving plates is uniformly and alternately fixedly connected to a single piece, with both ends of each of the first and second receiving plates respectively fixedly connected to the fixing plate, forming multiple grids of equal area; the fixing plate fixes the protective net to the first and second side plates, preventing the protective net from loosening due to the impact of coke during transportation, thus improving the stability of the device; the wear-resistant layer is fixedly connected to the surface of the protective net body; the wear-resistant layer improves the wear resistance of the protective net and extends the service life of the device.

[0019] Compared with the closest existing technology, the technical solution provided by this utility model has the following advantages:

[0020] Currently, iron objects worn and detached during transport pass through the iron separator at high speed with coke. Some iron objects buried beneath the coke are not adsorbed by the iron separator and enter the conveyor belt, posing a significant risk of belt damage. This invention addresses this issue by installing a protective net between the chute body, the first side plate, and the second side plate, with a wear-resistant layer on the surface of the net. This effectively prevents detached metal from entering the conveyor belt while simultaneously extending the service life of the protective net. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that in the description of this utility model, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0028] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a novel coke conveying line chute, comprising a chute body, a first side plate, a second side plate, and a protective net;

[0029] The first side plate and the second side plate are respectively welded to both sides of the chute body along its length to form a space that can accommodate the protective net.

[0030] The protective netting is fixed to the first and second side plates by welding to ensure the stability of the protective netting during the transportation of coke in the chute body and to prevent the protective netting from falling off.

[0031] The protective net includes a protective net body and a wear-resistant layer. The protective net body includes a fixing plate 1, a first receiving plate 2, and a second receiving plate 3. The fixing plate is a rectangular frame, and is fixedly connected to the first and second side plates respectively, securing the protective net between them. The length direction of the first receiving plate 2 is perpendicular to the length direction of the second receiving plate 3. Each first receiving plate 2 and second receiving plate 3 is uniformly and alternately fixedly connected together, with both ends of each first receiving plate 2 and second receiving plate 3 fixedly connected to the fixing plate 2, forming multiple grids 4 of equal area. The grids 4 formed by the protective net allow coke to pass through while preventing metal that has detached due to malfunction from entering subsequent equipment, thus avoiding damage to the equipment and extending its service life.

[0032] The wear-resistant layer is fixedly connected to the surface of the protective net body. By setting the wear-resistant layer on the protective net body, the damage to the protective net caused by the impact of coke during coke transportation is reduced, thereby increasing the service life of the protective net and reducing costs.

[0033] In this embodiment, the thickness of the protective net body is 150mm to avoid deformation of the protective net body due to the impact of coke transportation, which would affect the blocking effect of the protective net.

[0034] Preferably, the fixing plate 1 is welded to the first receiving plate 2, the fixing plate 1 is welded to the second receiving plate 3, and the first receiving plate 2 is welded to the second receiving plate 3; or, the fixing plate 1, the first receiving plate 2, and the second receiving plate 3 are integrated into one structure.

[0035] The connection method between the aforementioned fixing plate 1, the first receiving plate 2, and the second receiving plate 3 improves the stability of the device while giving it the advantages of simple structure, high weld strength, and low cost.

[0036] Preferably, the protective net body is made of Q345B low-alloy high-strength structural steel, and the wear-resistant layer is formed by welding DMD266 or DMD337 high-manganese steel welding rods onto the protective net body, with the DMD266 high-manganese steel welding rods having a welding thickness of 10mm.

[0037] The core and coating formulations of DMD266 are designed to match the chemical composition of its weld metal with that of high-manganese steel (typically containing 11-14% manganese), ensuring post-weld performance consistent with the base material. The weld metal has low hardness (approximately ~200 HB) in its post-weld state and exhibits good toughness. However, when subjected to strong impacts, pressure, or extrusion during operation, the surface undergoes rapid work hardening, significantly increasing the hardness to over 500 HB, thus forming an extremely hard and wear-resistant surface, while the inner layer retains its toughness to withstand impacts.

[0038] In this embodiment, a wear-resistant layer (10mm high) is formed on the Q345B material protective mesh surface by using DMD266 / DMD337 high manganese steel welding rods to weld over it, thereby improving its surface hardness and wear resistance and extending its service life.

[0039] In addition, because Q345B has good welding performance, the replacement process can involve patching the worn parts and re-welding them with DMD266 high manganese steel welding rods, which greatly reduces maintenance costs.

[0040] In this embodiment, the mesh 4 is 200mm × 200mm in size, with coke particles ranging from 25mm to 80mm in diameter and a tubular diameter of 350mm. Iron objects with a maximum length greater than 350mm entering the tubular mesh can cause scratches and damage to the conveyor belt. The protective mesh has holes designed to be 200mm × 200mm, with a diagonal length of approximately 282.8mm, less than 350mm, effectively reducing the risk of iron objects scratching the conveyor belt.

[0041] In summary, this utility model achieves the following technical effects:

[0042] (1) The protective netting of this utility model uses Q345B material and DMD266 / DMD337 high manganese steel welding rods to weld a wear-resistant layer (10mm high) on the facade to improve its surface hardness and wear resistance and extend its service life.

[0043] (2) By installing a protective net between the chute body, the first side plate and the second side plate, this utility model can effectively reduce the risk of iron objects scratching the belt.

[0044] (3) In the protective net of this utility model, DMD266 / DMD337 high manganese steel welding rods are used to weld a wear-resistant layer (10mm high) to improve its surface hardness and wear resistance and extend its service life.

[0045] (4) In this utility model, the fixing plate 1 is welded to the first side plate and the second side plate respectively to improve the stability of the device and avoid the impact of coke on the stability of the protective net, thereby affecting the effect of the protective net in blocking falling iron objects.

[0046] (5) In this utility model, the fixing plate 1, the first receiving plate 2 and the second receiving plate 3 are welded together or an integrated structure design is adopted, which simplifies the structure of the protective net and improves the stability of the device.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
