Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of coke vibrating screen cleaning, and more specifically, to a coke vibrating screen cleaning mechanism. Background Technology

[0002] In the coke production process of industries such as coking and metallurgy, the coke vibrating screen is a key piece of equipment for achieving coke particle size classification. The unobstructedness of its screen holes directly affects screening efficiency and product quality. During the screening process, coke contains fine particulate impurities such as coal powder and coke powder, which are prone to sticking and clogging at the screen holes, especially for small and medium-sized screen holes, where the accumulation of impurities is more prominent.

[0003] Currently, the traditional cleaning methods for coke vibrating screens have significant limitations: First, the cleaning precision is insufficient. Most methods, such as overall vibration, high-pressure air blowing, or manual knocking, are crude and cannot target individual blocked screen holes. Some hidden blockages cannot be cleared for a long time, resulting in a gradual reduction in the effective screening area and a decrease in screening efficiency. Second, the cleaning effect is unstable. High-pressure air can easily blow fine particulate impurities to other screen holes, causing secondary blockages. Manual cleaning is limited by the complexity of the screen surface structure, resulting in blind spots, and is labor-intensive and operates in a harsh environment.

[0004] Long-term blockage not only increases the operating load of equipment and aggravates screen wear, but also leads to excessive coke particle size after screening, affecting the stability of subsequent smelting processes. Therefore, developing a coke vibrating screen cleaning mechanism that can accurately locate and efficiently clear blocked screen holes has become an urgent need to solve industry pain points and improve production continuity. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a coke vibrating screen cleaning mechanism, which solves the technical problem that the existing technology has insufficient cleaning precision and mostly adopts extensive methods such as overall vibration, high-pressure air blowing or manual knocking, which makes it difficult to target and clean individual blocked screen holes.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a coke vibrating screen cleaning mechanism, comprising: A mounting frame and a housing, wherein the housing is disposed on top of the mounting frame; A movable frame and a drive assembly are provided, wherein the movable frame is disposed on the outside of the housing and is at a 90° angle to the housing, and the drive assembly is disposed between the movable frame and the housing; A cleaning component, the cleaning component being mounted on the movable frame; The cleaning assembly includes a side plate, which is fixed to one side surface of the movable frame. A pair of movable rods are movably connected to both ends of the side plate surface. A base plate is fixedly connected to the lower end of the movable rods. A number of cleaning needles are evenly distributed on the bottom surface of the base plate, and the distribution density of the cleaning needles matches that of the screen.

[0007] As a further technical solution, a connecting plate is connected to the top of the movable rod, a buffer spring is fitted on each of the movable rods, a drive motor is provided on the top of the housing, and an eccentric shaft is provided at the output end of the drive motor.

[0008] As a further technical solution, a transmission rod is rotatably connected between the top of the connecting plate and the eccentric shaft via a pin, and a cleaning roller is rotatably connected to the other side surface of the outer shell. A second motor is provided at one end of the side surface of the outer shell, and pulleys are provided at the output end of the second motor and one end of the cleaning roller.

[0009] As a further technical solution, the drive assembly includes a pair of guide rods, one end of the movable frame is movably mounted on the guide rods, and both ends of the housing are rotatably connected to drive wheels, one of which is driven to rotate by electricity.

[0010] As a further technical solution, a transmission belt is connected between the drive wheels, and the transmission belt is fixedly connected to both sides of the mobile frame.

[0011] As a further technical solution, the cross-section of the fixing frame is L-shaped, and the outer shell is connected to the fixing frame by a vertical linear drive.

[0013] As a further technical solution, the side surface of the fixing frame is provided with a plurality of fixing holes, and the side surface of the fixing frame and the side surface of the outer shell are on the same plane.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the cleaning component, through precise targeting design, solves the problem of insufficient precision in traditional cleaning methods.

[0023] like Figures 1-4 As shown, a coke vibrating screen cleaning mechanism according to an embodiment of the present disclosure includes: A mounting frame 1 and a housing 2, wherein the housing 2 is disposed on the top of the mounting frame 1; The movable frame 3 and the drive assembly 5 are provided. The movable frame 3 is disposed on the outside of the outer shell 2 and is 90° opposite to the outer shell 2. The drive assembly 5 is disposed between the movable frame 3 and the outer shell 2. Cleaning component 4 is disposed on the movable frame 3; The cleaning component 4 includes a side plate 4-1, which is fixed to one side surface of the movable frame 3. A pair of movable rods 4-2 are movably connected to both ends of the side plate 4-1. A base plate 4-3 is fixedly connected to the lower end of the movable rods 4-2. Several cleaning needles 4-4 are evenly distributed on the bottom surface of the base plate 4-3, and the distribution density of the cleaning needles 4-4 matches that of the screen. A connecting plate 4-5 is connected to the top of the movable rods 4-2. A buffer spring 4-6 is fitted on each movable rod 4-2. A drive motor 4-7 is provided on the top of the outer shell 2. An eccentric shaft 4-8 is provided at the output end of the drive motor 4-7. A transmission rod 4-9 is rotatably connected between the top of the connecting plate 4-5 and the eccentric shaft 4-8 via a pin. A sweeping roller 4-10 is rotatably connected to the other side surface of the outer shell 2. A second motor 4-11 is provided at one end of the side surface of the outer shell 2. A pulley 4-12 is provided at the output end of the second motor 4-11 and at one end of the sweeping roller 4-10.

[0024] In some examples, a cleaning assembly 4 is designed to achieve comprehensive cleaning of the coke vibrating screen. This assembly includes a side plate 4-1 on one side surface of the movable frame 3, which is a rigid support structure. A pair of movable rods 4-2 at both ends of the surface can slide vertically along the side plate 4-1. The bottom plate 4-3 at the lower end is fixed to the movable rods 4-2. Several cleaning needles 4-4 on the bottom surface correspond to the screen holes, and their distribution density matches the screen specifications, allowing for precise insertion into the screen holes to clear blockages. A connecting plate 4-5 at the top of the movable rods 4-2 connects multiple movable rods 4-2 into a whole. A buffer spring 4-6 on the rod is located between the side plate 4-1 and the bottom plate 4-3 to buffer the impact force when the cleaning needles 4-4 are inserted. The eccentric shaft 4-8 at the output end of the drive motor 4-7 at the top of the housing 2 is rotatably connected to the connecting plate 4-5 through a transmission rod 4-9, forming a crank-connecting rod structure, which drives the movable rods 4-2 to move up and down reciprocally. The cleaning roller 4-10 on the other side of the outer casing 2 is parallel to the screen surface and is driven to rotate by the second motor 4-11 through the pulley 4-12 and belt drive. The roller surface is equipped with a flexible cleaning brush.

[0025] During operation, the drive motor 4-7 rotates the eccentric shaft 4-8, and the transmission rod 4-9 pushes and pulls the connecting plate 4-5, causing the movable rod 4-2 to move the base plate 4-3 up and down. The cleaning needle 4-4 repeatedly inserts into the screen holes to clear the blockage of coke particles. The buffer spring 4-6 extends and retracts during the movement, reducing the rigid impact of the cleaning needle 4-4 on the screen. Simultaneously, the second motor 4-11 drives the sweeping roller 4-10 to rotate, and the sweeping brush sweeps off the coke residue on the screen surface, achieving comprehensive cleaning. The precise matching of the cleaning needle 4-4 with the screen holes ensures efficient unblocking and avoids missed cleaning; the buffer spring 4-6's cushioning effect protects the screen and extends its service life; the reciprocating motion driven by the eccentric shaft 4-8 makes the cleaning action continuous, adapting to the continuous operation of the vibrating screen; the rotating sweeping roller 4-10 covers the screen surface, working synergistically with the needle unblocking to improve the cleaning effect. This component effectively solves the clogging and residue problems of coke vibrating screens through multi-dimensional cleaning methods, ensuring screening efficiency.

[0026] like Figures 1-4 As shown, this embodiment proposes that the drive assembly 5 includes a pair of guide rods 5-1, one end of the movable frame 3 is movably mounted on the guide rods 5-1, and both ends of the housing 2 are rotatably connected to drive wheels 5-2, one of the drive wheels 5-2 is driven to rotate by electricity, and a transmission belt 5-3 is connected between the drive wheels 5-2, and the transmission belt 5-3 is fixedly connected to both sides of the movable frame 3.

[0027] In some examples, to achieve smooth movement of the movable frame 3 and ensure that the cleaning component 4 fully covers the screen, a drive component 5 is designed. This component includes a movable frame 3 with one end movably mounted on a pair of parallel guide rods 5-1. The guide rods 5-1 are horizontally fixed to the outer casing 2, restricting the movement direction of the movable frame 3 so that it can only move laterally along the rods, ensuring the relative position stability between the cleaning component 4 and the screen. The drive wheels 5-2 at both ends inside the outer casing 2 are rotatably connected by bearings, one of which is driven by a motor. The transmission belt 5-3 between the wheels is a closed loop, with its inner side meshing with the drive wheel 5-2 and its outer side fixedly connected to both sides of the movable frame 3, forming a synchronous transmission structure.

[0028] During operation, the motor drives the drive wheel 5-2 to rotate, and the transmission belt 5-3 moves with the wheel, causing the moving frame 3 to move laterally along the guide rod 5-1. Since the transmission belt 5-3 connects both sides of the moving frame 3, the force on the moving frame 3 is balanced, preventing deviation. The guide rod 5-1 provides support for the moving frame 3, reducing swaying during movement and ensuring stable operation of the cleaning assembly 4. The double-rod design of the guide rod 5-1 enhances the support rigidity and improves the stability of the moving frame 3. The synchronous transmission of the transmission belt 5-3 ensures consistent movement on both sides of the moving frame 3, preventing jamming. The meshing transmission between the drive wheel 5-2 and the transmission belt 5-3 enables controllable movement speed, adapting to different cleaning needs. The overall structure allows the moving frame 3 to cover the entire width of the screen, ensuring thorough cleaning. This assembly, through its stable guiding and transmission design, provides reliable power for the cleaning assembly 4, ensuring comprehensive and stable cleaning operations.

[0029] For example, such as Figure 1 As shown, the fixed frame 1 has an L-shaped cross-section, and the outer shell 2 is connected to the fixed frame 1 by a vertical linear drive.

[0030] In some examples, the mounting bracket 1 has an L-shaped cross-section, allowing it to be securely installed next to the vibrating screen, with the vertical portion providing support for the housing 2. The housing 2 is connected to the mounting bracket 1 via a vertical linear drive and its height can be adjusted to accommodate different screen sizes. This design ensures that the cleaning assembly 4 maintains the optimal distance from the screen, guaranteeing effective operation of the cleaning needles 4-4 and the sweeping rollers 4-10, thus improving cleaning flexibility and adaptability.

[0031] For example, such as Figure 4 As shown, the surface of the cleaning roller 4-10 is composed of rubber brushes.

[0032] In some examples, the rubber brushes on the surface of the cleaning rollers 4-10 are flexible and elastic. During cleaning, they effectively remove residual coke from the screen surface without damaging it. The rubber brushes are wear-resistant, have a long lifespan, and can adapt to the continuous working environment of the vibrating screen, while reducing friction noise with the screen, making the cleaning process smoother and more efficient.

[0033] For example, such as Figure 2 As shown, the side surface of the fixing frame 1 is provided with a plurality of fixing holes 6, and the side surface of the fixing frame 1 and the side surface of the outer shell 2 are on the same plane.

[0034] In some examples, several fixing holes 6 on the side surface of the fixing frame 1 are evenly distributed, facilitating its secure installation on the vibrating screen frame with bolts and preventing loosening during operation. The side surface of the fixing frame 1 and the outer casing 2 are on the same plane, ensuring a compact overall structure, reducing space occupation, and avoiding stress concentration caused by uneven surfaces, thus enhancing structural stability.

[0035] In actual use: The fixed frame 1 is installed next to the vibrating screen through the fixed hole 6. The height of the housing 2 is adjusted vertically and linearly to align the cleaning component 4 with the screen. The drive wheel 5-2 of the drive component 5 drives the transmission belt 5-3, and the moving frame 3 moves laterally along the guide rod 5-1 to cover the entire screen surface. In the cleaning component 4, the drive motor 4-7 drives the movable rod 4-2 to move up and down reciprocally through the eccentric shaft 4-8 and the transmission rod 4-9. The cleaning needle 4-4 on the bottom surface of the base plate 4-3 is precisely inserted into the screen hole to clear blockages, and the buffer spring 4-6 reduces the impact on the screen. At the same time, the second motor 4-11 drives the sweeping roller 4-10 to rotate, and the rubber brush sweeps off the residual coke on the surface, working together to complete a comprehensive cleaning. The moving frame 3 moves continuously to ensure that there are no dead corners in the cleaning.
