Description

Technical Field

[0001] This utility model relates to the field of bulk material conveying technology, specifically to a covered passageway for belt conveyors. Background Technology

[0002] Belt conveyors are an important form of bulk material transportation, especially in the metallurgical industry, where they are widely used in various units such as docks, raw material processing, ironmaking, sintering, pelletizing, coking, and roasting, playing a crucial role in transporting bulk materials throughout the plant. Among these components, the conveyor corridor is an essential part of the belt conveyor system. Its main functions include: supporting the middle section of the belt conveyor; facilitating observation, inspection, and passage for maintenance personnel, as well as providing temporary storage for small maintenance equipment; and serving as a passageway for related cables, lighting lines, water pipes, and compressed air pipelines.

[0003] Based on the degree of enclosure, conveyor corridors can be divided into wall-mounted enclosed corridors and hooded corridors. Architectural professionals typically only participate in the design of wall-mounted enclosed corridors, including the corridor walls, roof, doors, and windows. Therefore, wall-mounted enclosed corridors can achieve full enclosure, meeting the requirement in relevant regulations for fugitive emission control measures that "no visible smoke or dust should escape from dust-generating points and workshops." However, they have never participated in the design of hooded corridors.

[0004] Unlike wall-mounted enclosed corridors that enclose materials, conveyors, maintenance access routes, and cables, hooded corridors only enclose the materials themselves, leaving the maintenance access routes and cable piping on both sides of the belt conveyor unenclosed. This design is simpler and easier to process, manufacture, transport, install, and maintain. However, in actual production, when conveying materials with low moisture content using hooded corridor belt conveyors, the belt conveyor's cleaners cannot completely remove the material adhering to the return section. The remaining material adhering to the return section will spill along the entire length of the return section during operation due to the vibrations and shaking, causing environmental pollution and visible dust emission. This fails to meet the requirement in relevant regulations that "no visible smoke or dust should escape from dust-generating points and workshops."

[0005] Therefore, to solve the above problems, a covered walkway for belt conveyors is needed to solve the problem of dust leakage caused by material spillage along the way when conveying materials with low moisture content, and to comprehensively promote the implementation of ultra-low emissions in the steel industry, so that the covered walkway can be widely used. Utility Model Content

[0006] In view of this, the purpose of this utility model is to overcome the defects in the prior art and provide a covered corridor for belt conveyors, which can solve the problem of dust escape caused by material spillage along the way when conveying materials with low moisture content, comprehensively promote the implementation of ultra-low emissions in the steel industry, and enable the covered corridor to be widely used.

[0007] This utility model discloses a covered walkway for a belt conveyor, comprising a support body for supporting the feeding section of the belt conveyor, and a cover disposed on the support body to cover the feeding section of the belt conveyor. A protective door that can be controlled to open and close is provided between the support body and the cover. A material discharge baffle located below the feeding section of the belt conveyor is also provided on the support body. The protective door connects the cover and the material discharge baffle to form a protective structure that circumferentially encloses the feeding section of the belt conveyor.

[0008] Furthermore, the supporting body is provided with a mounting beam, and the protective door is detachably installed on the mounting beam via a mounting assembly.

[0009] Furthermore, the mounting assembly includes a mounting plate and a hook, and the mounting plate is provided with a limiting hole for engaging with the hook;

[0010] The hanging plate and hook are respectively installed on the protective door and the mounting beam.

[0011] Furthermore, the hook includes a limiting part that protrudes upward from the top surface of the mounting beam, the hanging plate has an inwardly protruding hooking part, and the limiting hole is opened in the hooking part.

[0012] Furthermore, the mounting beam is located near the bottom of the hood, and the mounting plate is located on the top surface of the protective door;

[0013] After the protective door is installed on the mounting beam via the mounting assembly, the top surface of the protective door is not lower than the top surface of the mounting beam.

[0014] Furthermore, a limiting beam is provided on the supporting body, and the limiting beam has a limiting groove; after the protective door is installed on the supporting body, at least one frame of the protective door is located in the limiting groove.

[0015] Furthermore, the limiting beam and the mounting beam are arranged opposite each other on the supporting body, and the limiting groove is opened on the limiting beam with the groove facing upward;

[0016] After the protective door is installed on the supporting body, the bottom edge of the protective door is located in the limiting groove.

[0017] Furthermore, the protective door is equipped with a handle.

[0018] Furthermore, the supporting body has an inspection passage located outside the enclosure structure.

[0019] Furthermore, there are multiple protective doors, which are sequentially connected and approach each other along the feeding direction of the belt conveyor feeding section.

[0020] The beneficial effects of this utility model are as follows: The hood-type corridor for belt conveyors disclosed in this utility model can solve the problem of dust leakage caused by material spillage along the conveyor when conveying materials with low moisture content by setting up an enclosure structure to circumferentially enclose the feeding section of the belt conveyor. This can comprehensively promote the implementation of ultra-low emissions in the steel industry and enable the hood-type corridor to be widely used. The protective door that is controlled to open and close can selectively open the enclosure structure according to the actual situation to clean up the powder falling to the discharge baffle in a closed manner, resulting in a higher powder recovery rate.

[0029] Figure 1As shown in the figure, the hood-type corridor for a belt conveyor in this embodiment includes a support body 1 for supporting the feeding section of the belt conveyor, and a hood 2 disposed on the support body 1 to cover the feeding section of the belt conveyor. The feeding section of the belt conveyor is located near the hood 2 at the top of the support body 1, so as to close the top of the enclosure structure. The hood 2 is an arch shape with an upward convex center. The hood 2 is continuous in the feeding direction of the feeding section of the belt conveyor, forming effective protection for the top of the feeding section of the belt conveyor. The hood 2 can be customized according to actual needs. Depending on the specific circumstances, options may be made for opening windows or using visual materials to facilitate observation of the working status of the belt conveyor's feeding section, thereby improving material handling safety. A controllable protective door 3 is installed between the support body 1 and the hood 2. A material drop baffle 4 is also installed on the support body 1 below the belt conveyor's feeding section. The material drop baffle 4 encloses the top of the enclosure structure. The protective door 3 comprises two doors located on either side of the belt conveyor's feeding section, connecting the hood 2 and the material drop baffle 4 to form a circumferentially enclosed enclosure structure for the belt conveyor's feeding section. By enclosing the belt conveyor's feeding section circumferentially with this enclosure structure, the problem of dust leakage caused by material spillage along the conveying route of materials with low moisture content in the hood-type corridor can be solved, comprehensively promoting the implementation of ultra-low emissions in the steel industry and enabling the widespread application of hood-type corridors. The controllable protective door 3 allows for selective opening of the enclosure structure based on actual conditions, enabling closed-loop cleaning of powder falling onto the material drop baffle 4, resulting in a higher powder recovery rate.

[0030] The door that is controlled to open and close can be a hinged door, a sliding door, or a lift door, etc., which will not be elaborated here.

[0031] In this embodiment, the support body 1 includes a support truss arranged along the feeding direction of the belt conveyor feeding section and a support main beam that sets the support truss at a designated position. The cross-section of the support truss is rectangular, and the support main beam includes several beams arranged along the feeding direction of the belt conveyor feeding section. The belt conveyor feeding section is located on top of the support truss and is covered by the machine cover 2.

[0032] In this embodiment, the supporting body 1 has an inspection channel 5 located outside the enclosure structure. The inspection channel 5 consists of two sets connected to both sides of the supporting truss. The two sets of inspection channels 5 are respectively set on both sides of the enclosure structure, and a guardrail 6 is set on the outside of the inspection channel 5 to improve safety. More specifically, a supporting beam runs through the middle of the vertical direction of the supporting truss. The supporting beam is set perpendicular to the feeding direction of the belt conveyor feeding section. A drop baffle 4 is set on the supporting beam to close the bottom of the enclosure structure. The middle of the drop baffle 4 protrudes upward and the height gradually decreases to both sides to form a slope that is inclined to the inspection channels 5 on both sides. This facilitates the concentration of the transported and dropped powder at a set position, making it easier to handle and improving cleaning efficiency.

[0033] In this embodiment, there are multiple protective doors 3, which are sequentially connected and approach each other along the feeding direction of the belt conveyor feeding section. The structure of the multiple protective doors 3 allows for flexible maintenance of corresponding positions, and the assembly is more convenient and adaptable, suitable for belt conveyor feeding sections of different lengths. In this solution, the multiple protective doors 3 that are sequentially connected and approach each other along the feeding direction of the belt conveyor feeding section are arranged in two rows on both sides of the supporting truss, so as to close both sides of the enclosure structure and control the opening and closing of the corresponding positions for cleaning, which is convenient to implement.

[0034] In this embodiment, a mounting beam 7 is provided on the supporting body 1, and the protective door 3 is detachably installed on the mounting beam 7 via a mounting assembly. The structure of the mounting assembly includes a bolt and nut mating structure, a hook 9 mating with a hanging component, or a locking structure with interlocking clips, etc. The protective door 3, which is detachably installed on the supporting body 1 via the mounting assembly, does not affect the space occupied by the maintenance passage 5 during installation and removal. It is a convenient way to use, and the structure is more stable, safer, more wind-resistant, and has fewer noise points and no abnormal noise during use.

[0035] In this embodiment, the mounting assembly includes a mounting plate 8 and a hook 9. The mounting plate 8 has corresponding limiting holes for engaging with the hook 9. The mounting plate 8 and the hook 9 are respectively disposed on the protective door 3 and the mounting beam 7. More specifically, as shown... Figure 4 and Figure 6 As shown, the mounting beam 7 is located near the bottom of the machine cover 2 on the support body 1. The machine cover 2 and the mounting beam 7 are enclosed or have an observation window. In this scheme, it is preferred to set an observation window to monitor the material conveying of the internal belt conveyor feeding section. The mounting beam 7 is a strip angle steel set along the feeding direction of the belt conveyor feeding section. The hook 9 includes a limiting part that protrudes upward from the top surface of the mounting beam 7. In this scheme, the hook 9 is a stud welded to the angle steel. The top of the stud protrudes from the top surface of the mounting beam 7 as a limiting part for hanging the hanging plate 8.

[0036] The hanging plate 8 is installed on the top surface of the protective door 3. The hanging plate 8 has an inwardly protruding hook-on part, where "inward" refers to the direction facing the inside of the enclosure structure. The limiting hole is opened in the hook-on part. In this solution, the protective door 3 is composed of a rectangular color steel plate and a door frame beam corresponding to the periphery of the color steel plate. The hanging plate 8 is also fixed to the top of the protective door 3 by welding, and the inwardly protruding hook-on part of the hanging plate 8 has a limiting hole that matches the limiting part. In use, the protective door 3 is raised or lowered on the hanging beam. The upper part of the bracket 7 is designed to more accurately limit the protective door 3 to the mounting beam 7 through the limiting part with the limiting hole. The structure is simple and convenient, and the protective door 3 can be stably installed on the mounting beam 7 without the need for a locking structure. After the protective door 3 is installed on the mounting beam 7 through the mounting assembly, the top surface of the protective door 3 is not lower than the top surface of the mounting beam 7, so as to achieve the protective effect. The position of the mounting beam 7 can also be located in the middle of the protective door 3 or other positions, preferably to serve the function of installing and supporting the protective door 3, which will not be elaborated here.

[0037] In this embodiment, multiple sets of mounting components are provided to improve the installation reliability of the protective door 3 on the mounting beam 7.

[0038] In this embodiment, the protective door 3 is provided with a handle 10. More specifically, the handle 10 is provided on the top of the protective door 3, and multiple handles 10 are provided, which facilitates raising or lowering the protective door 3, making the operation convenient and simple, facilitating local maintenance, and not damaging the exterior of the overall structure, thus improving the aesthetics.

[0039] In this embodiment, a limiting beam 11 is provided on the supporting body 1. The limiting beam 11 can also act as a threshold to block falling materials and reduce the dispersion of powder. The limiting beam 11 has a limiting groove. After the protective door 3 is installed on the supporting body 1, at least one edge of the protective door 3 is located in the limiting groove. The setting of the limiting groove can further limit the position of the protective door 3, improve structural stability, and reduce shaking. Preferably, the limiting beam 11 and the hanging beam 7 are arranged opposite to each other on the supporting body 1, and the opening of the limiting groove is opened on the limiting beam 11 with the groove facing upward. The limiting groove is a U-shaped groove. After the protective door 3 is installed on the supporting body 1, the bottom edge of the protective door 3 is located in the limiting groove. The structure is simple and convenient, saves materials, and can cooperate with the hanging component to limit the position of the protective door 3. The structure has better reliability and higher safety. It should be understood that the limiting beam 11 with the limiting groove is located outside the hanging beam 7 so that the protective door 3 falls vertically into the limiting groove and is simultaneously limited by the hanging beam 7, improving structural reliability and ease of operation.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
