Description

Technical Field

[0001] This application relates to the field of coking production technology in the coking industry, and in particular to a belt conveyor mechanism. Background Technology

[0002] During the operation of the coke conveyor belt, dropped and scattered materials tend to accumulate on the conveyor belt. If not cleaned in time, it will cause wear or even tearing of the conveyor belt, affecting the normal operation of the equipment. These materials are also very easy to adhere to the rotating surface of the rollers during operation, which can easily cause the idlers and rollers to rot and shorten their service life.

[0003] Currently, belt cleaning typically employs a single scraper plate to remove adhering coke powder and debris from the belt surface. However, due to the inherent elasticity of the belt, during actual operation, especially when the belt width is large, variations in tension and elastic deformation across different transverse sections result in an uneven or sagging surface. In such cases, a rigid, single-piece scraper plate struggles to achieve uniform contact across the entire belt width, leading to poor contact or gaps in certain areas. This prevents the scraper plate from effectively cleaning residue in these areas, creating blind spots or missed areas and impacting the overall cleaning efficiency. Utility Model Content

[0036] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0037] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure pertains.

[0038] During the operation of the coke conveyor belt, dropped and scattered materials tend to accumulate on the conveyor belt. If not cleaned in time, it will cause wear or even tearing of the conveyor belt, affecting the normal operation of the equipment. These materials are also very easy to adhere to the rotating surface of the rollers during operation, which can easily cause the idlers and rollers to rot and shorten their service life.

[0039] Currently, belt cleaning often employs a single scraper plate structure, where the scraper contacts the belt surface to remove adhering coke powder and debris. However, due to the inherent elasticity of the belt, during actual operation, especially when the belt width is large, differences in tension and elastic deformation occur in different transverse areas. This results in the belt surface not being completely flat, but exhibiting localized unevenness or sagging. In such cases, a rigid, single-piece scraper plate struggles to achieve uniform contact across the entire belt width, leading to poor contact or gaps in some areas. This prevents the scraper plate from effectively cleaning residue in these areas, creating cleaning "blind spots" or "missing points" and affecting the overall cleaning effect.

[0040] To solve the above-mentioned technical problems, this application provides a belt conveyor mechanism that allows scrapers in different areas to fit tightly against the belt, thereby effectively cleaning the residue in these areas, reducing cleaning blind spots or omissions, and improving the overall cleaning effect.

[0041] Example 1

[0042] like Figure 1 and Figure 2 As shown, a belt conveyor mechanism includes a belt 1 and scraper assembly 4. The belt 1 is used to convey materials. Multiple scraper assemblies 4 are disposed on one side of the belt 1 and arranged along the width direction of the belt 1. The scraper assembly 4 includes a scraper plate 42 and an elastic member 43. The scraper plate 42 contacts the belt 1 and is used to scrape off the material on the belt 1. The elastic member 43 is connected to the scraper plate 42 and is used to elastically deform to provide elastic force to the scraper plate 42 so that the scraper plate 42 remains in contact with the surface of the belt 1.

[0043] Belt 1 (also called "conveyor belt") is a continuously circulating flexible load-bearing component whose main function is to achieve continuous and efficient material conveying through its reciprocating motion. Belt 1 can be composed of a belt core (a skeleton material that bears tensile force) and a cover layer (rubber or other polymer materials that protect the belt core and provide friction and wear resistance). Belt 1 can be wound around a drive roller, a redirecting roller, and a series of idlers, and circulate under the drive of a drive unit. The front of belt 1 is used to carry and convey materials (such as coke). The return section of belt 1 returns to the origin after unloading. The surface of this section often adheres to material residues that have not been completely removed, which is the main cleaning target of the scraper assembly 4 in this application. Belt 1 has elasticity, flexibility, and a certain lateral stiffness. These characteristics directly affect the design of the scraper assembly 4 (such as the use of elastic element 43 in this scheme to adapt to the deformation of belt 1). The belt core of belt 1 can be made of fabric layers such as cotton canvas, nylon (NN), polyester (EP) or steel wire rope (steel wire rope core), and the covering layer can be made of natural or synthetic rubber. Additives such as wear-resistant, heat-resistant and oil-resistant can be added. It is suitable for conveying bulk materials such as coke, ore and coal.

[0044] The scraper assembly 4 (also known as the "scraper assembly") is a mechanical device installed on the surface of the belt 1 (which can be the return section). Its core function is to remove residual material adhering to the working or non-working surfaces of the belt 1, preventing material accumulation at the rollers and idlers, and ensuring stable equipment operation. Its basic components include a scraper plate 42 and an elastic element 43. The scraper plate 42 is a wear-resistant component that directly contacts the surface of the belt 1, removing adhering materials through friction or scraping. The elastic element 43 is an elastic element (such as a spring, rubber block, polyurethane buffer, etc.) that provides continuous preload to the scraper plate 42, allowing it to adaptively conform to the undulations of the belt 1 surface. This application replaces the traditional "integral rigid scraper" with "multiple independent scraper assemblies 4 with elastic clamping," achieving zoned adaptive conforming, thereby solving the problem of blind spots in cleaning caused by uneven tension on wide belts 1. The scraper plate 42 can be a V-shaped or straight rigid scraper plate, made of a single piece of alloy steel or polyurethane, rigidly fixed, simple and durable. Each scraper blade 42 in the scraper assembly 4 is equipped with an independent elastic element 43 (such as a spring). Each scraper blade can float independently, adapting to local deformation of the belt 1, ensuring good fit, reducing blind spots and damage to the belt 1, and ensuring uniform contact pressure. Multiple relatively independent scraping assemblies are arranged along the width of the belt 1 to achieve zoned control. When a certain area of ​​the belt 1 sags or bulges, the corresponding scraper blade 42 can move slightly up and down to maintain contact and avoid gaps. Adjacent scraper blades 42 can be closely arranged (gap ≤ 5mm) to form a cleaning surface that is almost a "whole plate" but has "flexible adaptability".

[0045] Compared to existing technologies, this disclosure provides multiple scraping components 4 arranged along the width of the belt 1 to correspond to multiple areas of the belt 1. By providing elastic elements 43 to correspond to scraping plates 42 in different areas, the elastic elements 43 can elastically deform according to the tension of the belt 1, so that the scraping plates 42 in different areas can be tightly attached to the belt 1, thereby effectively cleaning the residue in these areas, reducing cleaning blind spots or leaks, and improving the overall cleaning effect.

[0046] like Figure 2 As shown, in some modified embodiments of this application, a support frame 2 is also included. The support frame 2 is disposed on one side of the belt 1, and the elastic element 43 is disposed between the support frame 2 and the scraper 42.

[0047] The support frame 2 provides a stable mounting base for the scraper assembly 4. An elastic element 43 is positioned between the support frame 2 and the scraper plate 42, forming a force transmission structure of "support frame 2 → elastic element 43 → scraper plate 42". Specifically, the support frame 2 serves as a fixed reference, ensuring the overall stability of the scraper assembly 4. One end of the elastic element 43 is connected to or abuts against the support frame 2, while the other end acts on the scraper plate 42, applying a preload towards the belt 1. Under the action of the elastic element 43, the scraper plate 42 is pressed against the surface of the belt 1, and can float up and down due to the compression or rebound of the elastic element 43 when the belt 1 undulates, thus achieving adaptive fit.

[0048] With the introduction of support frame 2, the installation and force path of the entire scraping assembly 4 become clearer. Support frame 2 bears the reaction force, elastic element 43 provides elastic clamping, and scraper plate 42 performs the cleaning task, with each component having a distinct function. Support frame 2 can be pre-installed on the conveyor, and multiple scraping assemblies 4 can be modularly installed on the same support frame 2, facilitating alignment, debugging, and later replacement. Support frame 2 provides rigid support for elastic element 43 and scraper plate 42, preventing scraping failure due to local deformation or vibration of the frame and improving overall operational stability.

[0049] The support frame 2 can support various arrangements of the elastic element 43. For example, the elastic element 43 can be a compression spring structure, with the elastic element 43 (such as a coil spring) arranged vertically or inclined between the support frame 2 and the scraper plate 42. The support frame 2 can include a support plate 21, with the elastic element 43 disposed between the support plate 21 and the scraper plate 42. The elastic element 43 can also be a torsion spring structure, with the scraper plate 42 rotating around an axis, and the torsion spring installed at the pivot, one end connected to the support frame 2 and the other end connected to the scraper plate 42. The elastic element 43 can also be a rubber buffer block structure, which uses the compression deformation of rubber to provide elasticity, with a simple structure and no maintenance required.

[0050] like Figure 1 and Figure 2 As shown, in some modified embodiments of this application, a support rod 3 is also included, which is connected to the support frame 2; wherein, the scraper assembly 4 also includes a sleeve 41, which is connected to the scraper plate 42 and is rotatably connected to the support rod 3.

[0051] The support rod 3 (also called a "rotating shaft" or "installation shaft") is a long, rigid rod fixed to the support frame 2, arranged horizontally along the width of the belt 1, serving as a common or segmented rotation axis for multiple scraping assemblies 4. It provides mechanical support for the scraping assemblies 4, acts as a rotation axis, and cooperates with the sleeve 41 to achieve the rotation of the scraper plate 42. It can also withstand the reaction force and vibration load generated during the scraping process. The support rod 3 can be a solid round steel rod, made of ordinary carbon steel (such as Q235) or alloy steel (such as 45# steel), with a galvanized or blackened surface treatment, suitable for cost-sensitive and dry working conditions. The support rod 3 can also be a stainless steel rod, made of 304 or 316L stainless steel, with a polished surface, suitable for coke conveying, mining, humid, and corrosive environments.

[0052] The sleeve 41 (also called the "connecting sleeve") is a ring-shaped or tubular component fixedly connected to the scraper 42. Its inner hole is fitted onto the support rod 3, forming a sliding or rolling fit. It is the direct carrier for the scraper 42 to rotate around its axis. The sleeve 41 can connect the scraper 42 and the support rod 3; the sleeve 41 can also form a rotating pair, allowing the scraper 42 to rotate around the support rod 3; the sleeve 41 can also bear radial loads and transmit the preload of the elastic element 43. The sleeve 41 can be a straight-through metal sleeve 41, a straight cylinder made of brass, bronze, or stainless steel, with no sealing at both ends, directly sliding and rubbing against the support rod 3, with a simple structure and low cost. The sleeve 41 can also be an oil-impregnated bearing sleeve 41 (powder metallurgy), made of porous bronze material, with the inside impregnated with lubricating oil, connected to the support rod 3 using a self-lubricating sliding bearing, which can be used in maintenance-free scenarios.

[0053] The sleeve 41 can be fixedly connected to the scraper 42 (or integrally formed) and rotatably connected to the support rod 3, allowing the scraper 42 to rotate around the axis of the support rod 3 at a limited angle. When the surface of the belt 1 experiences local undulations due to uneven tension or deformation of the idler roller, the scraper 42, under the action of the elastic element 43, can rotate around the support rod 3 via the sleeve 41 to automatically adjust its contact angle with the surface of the belt 1, achieving a tighter and more uniform fit, effectively avoiding gaps or excessive wear caused by rigid contact. Since the scraper 42 can rotate with the slight movement of the belt 1, it reduces sliding friction and local stress concentration between the scraper 42 and the belt 1, thereby reducing the wear rate of both and extending their service life. Multiple scraper components 4 can be sleeved on the same support rod 3 via the sleeve 41, forming a continuous arrangement along the width direction. This facilitates installation and alignment, and allows for individual disassembly and replacement of a single unit during maintenance without affecting the overall structure. The support rod 3 can be fixedly connected to the support frame 2 to improve the stability of the support.

[0054] like Figure 1 and Figure 2As shown, in some modified embodiments of this application, a blowing assembly 5 is also included. The blowing assembly 5 is connected to the support rod 3 and faces the belt 1 for blowing and cleaning the belt 1.

[0055] The jetting assembly 5 refers to a device capable of generating a directional high-speed airflow (or an air-water mixture), installed downstream or upstream of the scraper assembly 4. The jetting assembly 5 can use compressed air or airflow generated by a fan to blow away fine particles, dust, or wet materials that the scraper 42 cannot completely remove; in a humid environment, it can prevent moisture from accumulating on the surface of the belt 1 and reduce material adhesion.

[0056] Together with the scraper 42, it forms a composite cleaning mode of "scraping first and then blowing" or "scraping and blowing simultaneously", which improves the overall cleaning efficiency, prevents materials from accumulating at the bottom of the rollers, idlers or conveyors, and reduces the frequency of maintenance.

[0057] The blowing assembly 5 can be a pure airflow blowing structure, using compressed air or blower airflow to dry materials (such as coke, dry coal powder), which is energy-efficient and highly effective. The blowing assembly 5 can also be a gas-liquid mixed blowing structure, where compressed air drives atomized water to form a gas-water mist that moistens and sticks the material, providing both cleaning and dust suppression functions. The blowing assembly 5 can also be a pulse blowing structure, providing intermittent blowing, saving energy, suitable for non-continuous adhesion scenarios, and extending equipment life. Multiple blowing assemblies 5 can be set, with each blowing assembly 5 corresponding to a scraper assembly 4.

[0058] Metal clamps can be used to fix the jetting assembly 5 to the support rod 3, making installation convenient and adjustable; a mounting plate can also be welded to the support rod 3, and the jetting pipe can be fixed with bolts; the support rod 3 can also serve as a hollow air passage (such as drilling holes in stainless steel pipes), allowing air to pass through internally and spray out externally, resulting in a compact structure.

[0059] like Figure 1 and Figure 2 As shown, in some modified embodiments of this application, the support rod 3 has an internal air passage that communicates with the spray assembly 5. The support rod 3 can be a hollow structure with an axially arranged air passage (i.e., an internal through hole or pipe) inside, which communicates with the spray assembly 5 to deliver compressed air or a gas-liquid mixture to the spray assembly 5. The support rod 3 can be made of hollow tubing (such as stainless steel tubing, aluminum alloy tubing, etc.), serving as both the rotation axis of the scraper 42 and the main channel for airflow transmission. The air passage penetrates the axial inner hole of the support rod 3, forming a continuous fluid path, equivalent to a concealed air supply pipe. One end of the air passage is connected to an external air source (through a connector, rotary connector, or fixed interface), and the other end is connected to the air inlet of the spray assembly 5, or directly communicates with the spray pipe through a side hole, and then distributes the air to the spray pipe or nozzle.

[0060] like Figure 1 and Figure 2As shown, in some modified embodiments of this application, the spray assembly 5 includes a nozzle 51 and a one-way valve 52. The nozzle 51 is connected to the support rod 3, and the one-way valve 52 is mounted on the nozzle 51. The nozzle 51 can communicate with the internal air passage of the support rod 3 and is positioned towards the surface of the belt 1 for directional spraying of airflow or gas-liquid mixture to achieve cleaning of the surface of the belt 1. The one-way valve 52 can be installed in the fluid passage of the nozzle 51 (or integrated inside the nozzle 51) to allow fluid to flow only from the air passage towards the nozzle 51, preventing external materials, dust, or liquids from flowing back into the air passage or the interior of the support rod 3.

[0061] Nozzle 51 is a nozzle device with a specific outflow structure. It can be made of metal or engineering plastic and can be in the form of a fan-shaped, circular, or flat jet to accelerate and directionally eject airflow or gas-liquid mixture. Nozzle 51 can control the spray angle, coverage width, and impact force to achieve a highly efficient and uniform purging effect.

[0062] One-way valve 52 is a valve device that allows fluid to flow in only one direction. It can be spring-loaded, ball-type, or diaphragm-type. When the air source is shut off or the pressure drops, it prevents dust, moisture, or fine materials in the belt 1 area from entering the air passage through the nozzle 51 in the reverse direction. This avoids external impurities from entering the spray system and causing nozzle or air passage blockage, maintains a slight positive pressure at the end of the system, and enhances the dust prevention effect.

[0063] The nozzle 51 can be directly threaded or welded to the side outlet of the support rod 3, or connected to a short pipe / branch pipe leading from the support rod 3. Multiple nozzles 51 can be evenly distributed along the width of the belt 1 to ensure full coverage. The one-way valve 52 can be integrated inside the nozzle 51 to form a single structure with a simple appearance and good sealing performance. The one-way valve 52 can also be installed on the connecting pipe between the nozzle 51 and the support rod 3 for easy maintenance and replacement. For example, an integrated nozzle 51 with a built-in one-way valve 52 can be used, which has a compact structure, fast response, and excellent leak-proof performance.

[0064] like Figure 1 and Figure 2As shown, in some modified embodiments of this application, the sleeve 41 is provided with an opening, and the nozzle 51 extends at least partially out of the opening. The portion of the nozzle 51 passing through the opening can extend toward the surface of the belt 1, allowing the nozzle 51 to directly spray airflow from inside or laterally of the sleeve 41, achieving close-range, directional blowing of the surface of the belt 1. Spatially integrating the mechanical structure (especially the sleeve 41) of the blowing assembly 5 and the scraping assembly 4 achieves precise positioning of the airflow outlet and a highly compact structure, which is particularly suitable for working conditions with limited space or high requirements for the blowing angle. For example, one or more axial or oblique openings (such as elongated grooves, circular holes, etc.) can be provided on the sleeve 41. The nozzle 51 is partially embedded inside the sleeve 41, with its nozzle end extending out from the opening, directly exposed to the external space, and aligned with the surface of the belt 1. The nozzle 51 can communicate with the air passage of the support rod 3 through an internal channel (for example, the root of the nozzle 51 is connected to the air passage of the support rod 3, or connected through a micro-pipe), forming a complete fluid passage.

[0065] like Figure 1 and Figure 2 As shown, in some modified embodiments of this application, the support rod 3 is rotatably connected to the support frame 2. This rotatable connection means that the support rod 3 is mounted on the support plate 21 of the support frame 2 via bearings, bushings 22, or a hinged structure, allowing for slight rotation within the mounting plane rather than a completely rigid fixation. This enables the entire support rod 3 and the multiple nozzles mounted on it to be finely adjusted as a whole, facilitating the adjustment of the spraying position. For example, as... Figure 3 As shown, the support frame 2 may include a bushing 22 and a support plate 21. The bushing 22 and the support plate 21 are fixedly connected, and the support plate 21 is rotatably connected to the support rod 3 through the bushing 22. The opening on the sleeve 41 can extend circumferentially to guide the spray assembly 5, thereby facilitating the adjustment of the spray angle. In addition, when the belt 1 experiences slight "deviation" or "edge sagging", the support rod 3 can rotate slightly with the belt 1, causing all scraper blades 42 to adjust their angles synchronously, ensuring that the entire row of scraper blades 42 always maintains good contact with the surface of the belt 1.

[0066] like Figure 1 and Figure 2As shown, in some modified embodiments of this application, a lifting rod 6 is also included. The lifting rod 6 is connected to the support frame 2 and is used to move the support frame 2 closer to or away from the belt 1. It is capable of moving vertically and is used to move the support frame 2 and the scraper assembly 4 mounted on it closer to or away from the surface of the belt 1, thereby adjusting the contact pressure between the scraper plate 42 and the belt 1 or disengaging it for easy replacement. The lifting rod 6 is a rod-shaped or screw-shaped component that can move vertically (or inclined), serving as the height adjustment actuator for the support frame 2. The support frame 2 is a rigid frame that supports multiple components (including the support rod 3, scraper plate 42, spray assembly 5, etc.), and its overall lifting is achieved through the lifting rod 6. During initial installation and adjustment, the lifting rod 6 can precisely adjust the initial contact height between the scraper 42 and the belt 1. When the scraper 42 or the belt 1 cover layer wears, the effective contact pressure can be restored by adjusting downwards. When replacing the belt 1, cleaning the rollers, or repairing the idlers, the entire scraper assembly 4 can be lowered as a whole to avoid interference; it can also prevent the scraper 42 from being pressed too tightly, causing damage to the belt 1, or too loosely, resulting in incomplete cleaning. The lifting rod 6 can be a lead screw, threadedly engaged with the support frame 2. Rotating the lead screw can raise or lower the support frame 2, providing high precision and good self-locking, and can be operated manually or electrically. The lifting rod 6 can also be a hydraulic or pneumatic cylinder structure, with the hydraulic cylinder or pneumatic cylinder piston rod connected to the support frame 2, driving the lifting and lowering through pressure.

[0067] In some modified embodiments of this application, adjacent scraper blades 42 are bonded together to cover the entire width of the belt 1. Multiple scraper blades 42 are arranged sequentially along the width direction of the belt 1, with the sides of adjacent scraper blades 42 bonded together to continuously cover the entire working width of the belt 1, avoiding blind spots for material residue in the lateral direction. The sides of adjacent scraper blades 42 are in direct contact without significant gaps, or only with minor functional gaps (less than 1 mm) due to machining and assembly tolerances. This ensures that scraper blades 42 are in contact with the surface of the belt 1 throughout the entire width direction from one edge to the other, forming a continuous and essentially uninterrupted cleaning band. Although the scraper blades 42 are bonded laterally, each scraper blade 42 is still independently pressed against the belt 1 by an elastic element 43 and can float independently with the local undulations of the belt 1, achieving a composite working mode of physical bonding plus dynamic independence.

[0068] like Figure 1As shown, in some modified embodiments of this application, the gap between adjacent scraper blades 42 is 1-3 mm. This gap is used to accommodate manufacturing and assembly tolerances, adapt to the thermal expansion and contraction of materials caused by temperature changes, and prevent material embedding that could cause the scraper blades 42 to jam, while ensuring no significant material leakage during the cleaning process. Components such as the scraper blades 42, support rods 3, and sleeves 41 may have dimensional and positional deviations during processing and installation. A 1-3 mm gap can prevent forced assembly or structural stress caused by accumulated errors. Under high-temperature conditions such as coke conveying, metal components (such as support rods 3) and scraper blade materials (such as polyurethane and steel) will expand due to temperature rise. A 1-3 mm gap can effectively absorb axial thermal deformation, preventing the scraper blades 42 from being squeezed and deformed or the support structure from twisting. A completely gapless "zero-gap" fit can easily cause fine materials such as coke powder and coal dust to embed in the gaps, causing the scraper blades 42 to jam or fail to float. A small gap can reduce the risk of material jamming while still effectively blocking most of the material from passing through. The 1–3 mm gap is much smaller than the particle size of typical coke or pulverized coal (usually >5 mm), so very few intact particles pass through here; even if a small amount of fine powder passes through, it can be further removed by the subsequent blow-through assembly 55 or the empty section cleaner, and the overall cleaning effect is not significantly affected. The tiny gap facilitates the removal and replacement of individual scraper blades 42 without the need to remove adjacent units first.

[0069] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
