Technical Field
[0001] This utility model relates to the field of vibrating filter technology, specifically a filter device with vibration function. Background Technology
[0002] The vibrating filter screen device is a high-efficiency separation equipment that combines vibration technology with a screen. Its core function is to use vibration to prevent material blockage and improve processing efficiency. The main components include a screen body, multiple layers of screens, a vibrating motor (or electromagnetic vibrator), and a shock absorption device. During operation, the vibration source drives the screen to vibrate regularly (circular, linear, or elliptical trajectory), causing the material to be evenly distributed and continuously agitated on the screen surface—fine particles pass through quickly, while coarse materials are conveyed along the screen surface to the outlet, achieving continuous automated grading. This device precisely controls separation accuracy by adjusting the amplitude, frequency, and screen aperture. It is widely used in solid-liquid separation or particle size screening in industries such as mining (ore screening), chemicals (powder removal), food (raw material filtration), and pharmaceuticals (particle grading). It boasts advantages such as strong anti-clogging capabilities, large processing capacity, and convenient maintenance, making it one of the key pieces of equipment in modern industrial production lines.
[0003] Currently, traditional vibration filtration devices do not have a device for quick filter replacement. Operators need to clean the filter frequently, which reduces production efficiency. Furthermore, when the filter needs to be replaced, the machine needs to be disassembled, which is inconvenient. Therefore, this utility model provides a vibration filtration device with quick filter replacement. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a filter screen device with vibration function to solve the technical problem that vibration filter devices cannot quickly replace the filter screen.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter device with vibration function, comprising a filter device, a movable cover provided on the upper inner side of the filter device, a vibrating plate provided below the movable cover, a filter screen provided between the movable cover and the vibrating plate, first support frames provided on both sides of the vibrating plate, the first support frames on both sides being rotatably connected by a first roller and a second roller, bearing seats provided on both sides of the first roller and the second roller, a roller motor provided above the first support frame, one end of the filter screen being wound around the outside of the first roller and the second roller, and the roller motor being used to drive the first roller and the second roller to rotate.
[0006] By adopting the above technical solution, the filtration device can efficiently realize the automatic replacement and recycling of the filter screen through the coordinated work of the first and second rollers. This avoids the need to disassemble the main unit in traditional equipment. Operators can directly switch between the old and new filter screens with the help of the roller system driven by the roller motor, which significantly simplifies the maintenance process and reduces the risk of downtime. At the same time, the double roller structure of this design, supported by the first support frame and bearing seat, ensures the flat laying and stable tension of the filter screen on the vibrating plate, preventing wrinkles or displacement problems, thereby improving separation accuracy and material processing efficiency.
[0007] Furthermore, a lifting mechanism is provided above the movable cover. The lifting mechanism includes a cylinder, a movable plate is provided below the cylinder, and telescopic rods are provided on both sides of the movable plate. The telescopic rods are connected to the movable cover.
[0008] By adopting the above technical solution, the lifting mechanism, driven by a cylinder, moves the plate and extends the telescopic rod, providing a one-button opening and closing mechanism to raise or lower the movable cover. This greatly simplifies the operator's workload, allowing users to expose the filter screen without tools or additional auxiliary equipment, facilitating quick cleaning or inspection, reducing human error and maintenance time. Simultaneously, the linkage structure between the moving plate and the telescopic rod ensures the smooth movement of the movable cover, avoiding jamming or seal failure, and improving the overall system's durability and safety. This lifting design is also compatible with different material properties, such as viscous solid-liquid mixtures.
[0009] Furthermore, a fixing plate is provided above the first support frame, and the fixing plate is fixedly connected to the first support frame. The fixing plate is used to fix the cylinder.
[0010] By adopting the above technical solution, the fixing plate is directly fixed to the first support frame of the filter device, providing a rigid support foundation for the cylinder of the lifting mechanism, ensuring the stability and positioning accuracy of the cylinder during reciprocating motion. This eliminates the risk of structural loosening under vibration interference, allowing the movable cover to accurately align and press the filter screen, ensuring the airtightness and efficiency of the separation process. At the same time, this fixing design also simplifies the assembly and maintenance process of the device. Operators do not need to worry about the displacement of the fixing components when inspecting or replacing parts, reducing the overall maintenance complexity.
[0011] Furthermore, a collection trough is provided below the vibrating plate. The collection trough is inclined, and a discharge port is provided on the outer side of the collection trough. A vibration motor is provided below the collection trough.
[0012] By adopting the above technical solution, the collection trough under the vibrating plate is designed with an inclined surface and combined with the discharge port, realizing the automated collection and rapid discharge of fine particulate materials. This avoids the problem of secondary retention or contamination of materials after screening, ensuring that the separated products are directly transported to external containers or subsequent processes, improving the continuity of processing and output quality. At the same time, the setting of the vibration motor directly drives the vibrating plate to generate regular vibration, effectively preventing the problem of filter screen clogging and improving the dispersion and screening efficiency of materials on the screen surface.
[0013] Furthermore, a first fixing ring is provided below the vibrating plate, and the vibrating plate and the first fixing ring are connected by a vibration spring elastic module.
[0014] By adopting the above technical solution, the vibrating plate is elastically connected to the first fixed ring through the vibration spring, creating a mechanism for buffering vibration transmission, reducing the mechanical stress and wear risk of the overall device. This ensures that the vibration energy is concentrated on the surface of the filter screen and does not diffuse to the support structure, significantly extending the equipment life and reducing the failure frequency. At the same time, the design of this elastic module also improves the uniformity of the movement of the vibrating plate, so that the material is evenly distributed during the screening process, avoiding local overload or screen breakage.
[0015] Furthermore, a second fixing ring is provided below the first fixing ring, and the first fixing ring is fixedly connected to the second fixing ring through a second support frame. Several omnidirectional wheels are provided below the second fixing ring.
[0016] By adopting the above technical solution, the first and second fixed rings are fixedly connected by the second support frame, constructing a stable support frame that provides a reliable foundation for the vibration module. This ensures that the energy generated by the vibrating plate during vibration is effectively isolated, preventing its transmission to the external environment or the ground, thereby improving operational safety and equipment stability. Simultaneously, the casters located below the second fixed ring give the device high mobility, allowing operators to easily move the entire filtration unit to adapt to different workplaces or production line layouts, avoiding the constraints of fixed installation and relocation costs.
[0017] Furthermore, a filter screen groove is provided on the left side of the second fixing ring, and a waste screen groove is provided on the right side of the second fixing ring.
[0018] By adopting the above technical solution, the filter screen trough and waste screen trough are respectively set on the left and right sides of the second fixing ring, realizing independent storage and automatic classification of new and old filter screens. This simplifies material management for operators during the replacement process and avoids the problem of filter screens being scattered or mixed in traditional equipment. It ensures that waste screens can be directly recycled to the waste screen trough, and new screens are taken from the filter screen trough, improving the orderliness and efficiency of the workflow. At the same time, the dual-trough design also reduces the risk of cross-contamination of contaminants. Especially in applications with high cleanliness requirements such as the pharmaceutical or food industries, it can maintain environmental hygiene and material purity.
[0019] In summary, the present invention has the following main advantages: 1. This utility model achieves automatic filter screen replacement through the coordinated rotation of the first and second rollers in the filtration device. Operators can replace the screen during the running interval without disassembling the main unit, which significantly reduces downtime and manual intervention. The roller motor drives the double rollers to run smoothly on the first support frame through the bearing seat, ensuring uniform tension and no wrinkles on the filter screen, and maintaining high-precision screening stability.
[0020] 2. This utility model uses a cylinder in the lifting mechanism to push the moving plate and the telescopic rod to control the lifting or pressing of the movable cover, quickly exposing or sealing the working surface of the vibrating plate, simplifying maintenance access operations. The fixed plate provides rigid support for the cylinder, avoiding the risk of displacement caused by vibration interference. The vibrating motor drives the vibrating plate to generate directional vibration, and the energy is transmitted to the first fixed ring through the vibration spring. Then, the second support frame and the second fixed ring are isolated from external vibration through the universal wheel, which not only improves screening efficiency but also protects the structural integrity of the equipment.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0024] In this embodiment: A filter device with vibration function, such as Figure 1-4As shown, the system includes a filter device 1. A movable cover 3 is located on the upper inner side of the filter device 1. A vibrating plate 20 is located below the movable cover 3. A filter screen 9 is positioned between the movable cover 3 and the vibrating plate 20. First support frames 5 are located on both sides of the vibrating plate 20. The first support frames 5 are rotatably connected by a first roller 6 and a second roller 61. Bearing seats 8 are located on both sides of the first roller 6 and the second roller 61. A roller motor 7 is located above the first support frames 5. One end of the filter screen 9 is wound around the outside of the first roller 6 and the second roller 61. The roller motor 7 drives the first roller 6 and the second roller 61 to rotate. Through the coordinated operation of the first roller 6 and the second roller 61, the filter device 1 can efficiently achieve filtration. The automatic replacement and recycling of filter screen 9 avoids the need to disassemble the main unit as required in traditional equipment. Operators can directly switch between old and new filter screens using the roller system driven by the roller motor 7, significantly simplifying the maintenance process and reducing downtime risks. At the same time, the dual roller structure of this design, supported by the first support frame 5 and bearing seat 8, ensures that the filter screen 9 is laid flat and under stable tension on the vibrating plate 20, preventing wrinkles or displacement problems, thereby improving separation accuracy and material processing efficiency. In addition, the combination design of movable cover 3 and vibrating plate 20 also solves the clogging problem, allowing the device to maintain high flow during continuous operation. It is suitable for high-load industrial environments such as mines or chemical plants, and can maintain long-term reliability without frequent manual intervention.
[0025] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A lifting mechanism 2 is provided above the movable cover 3. The lifting mechanism 2 includes a cylinder 203. A moving plate 201 is provided below the cylinder 203. Telescopic rods 202 are provided on both sides of the moving plate 201. The telescopic rods 202 are connected to the movable cover 3. The lifting mechanism 2 is driven by the cylinder 203 to move the moving plate 201 and the telescopic rods 202, providing a one-button opening and closing mechanism to raise or lower the movable cover 3. This greatly simplifies the workload of operators. Users can expose the filter screen 9 without the need for tools or additional auxiliary equipment, which facilitates quick cleaning or inspection and reduces human error and maintenance time. At the same time, the linkage structure of the moving plate 201 and the telescopic rods 202 ensures the smooth movement of the movable cover 3, avoids jamming or sealing failure, and improves the durability and safety of the overall system. This lifting design is also compatible with different material properties, such as viscous solid-liquid mixtures. While avoiding material spillage, it maintains the internal sealing integrity of the device, expands the applicability of the device in the pharmaceutical or food industries, and ensures that the production environment meets strict hygiene and operating standards.
[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4A fixing plate 4 is provided above the first support frame 5, and the fixing plate 4 is fixedly connected to the first support frame 5. The fixing plate 4 is used to fix the cylinder 203. By directly fixing the fixing plate 4 to the first support frame 5 of the filter device 1, the fixing plate 4 provides a rigid support foundation for the cylinder 203 of the lifting mechanism 2, ensuring the stability and positioning accuracy of the cylinder 203 in reciprocating motion. This eliminates the risk of structural loosening under vibration interference, allowing the movable cover 3 to accurately align and press the filter screen 9, ensuring the airtightness and efficiency of the separation process. At the same time, this fixing design also simplifies the assembly and maintenance process of the device. Operators do not need to worry about the displacement of the fixing components when inspecting or replacing parts, reducing the overall maintenance complexity. In addition, the fixing plate 4 also optimizes the spatial layout. The collaborative work with components such as the first roller 6 and the second roller 61 reduces redundant parts, improves the compactness of the overall structure, and is suitable for confined spaces or mobile application scenarios.
[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A collection trough 10 is located below the vibrating plate 20. The collection trough 10 is inclined, and a discharge port 11 is located on the outer side of the collection trough 10. A vibration motor 13 is located below the collection trough 10. The inclined design of the collection trough 10 below the vibrating plate 20, combined with the discharge port 11, enables automated collection and rapid discharge of fine particulate materials. This avoids secondary retention or contamination of materials after screening, ensuring that the separated products are directly transported to external containers or subsequent processes, improving processing continuity and output quality. At the same time, the vibration motor 13 directly drives the vibrating plate 20 to generate regular vibration, effectively preventing the clogging of the filter screen 9 and improving the dispersion and screening efficiency of materials on the screen surface. The cooperation between this vibration source and the collection trough 10 also enhances the solid-liquid separation effect, especially when processing wet or high-viscosity materials, reducing residue accumulation and enabling unattended operation of the equipment in demanding industries such as chemical or mining.
[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4A first fixing ring 14 is provided below the vibrating plate 20. The vibrating plate 20 and the first fixing ring 14 are connected by a vibration spring 12 elastic module. The vibration plate 20 and the first fixing ring 14 are elastically connected by the vibration spring 12, which creates a mechanism for buffering vibration transmission, reducing the mechanical stress and wear risk of the overall device. This ensures that the vibration energy is concentrated on the surface of the filter screen 9 and does not diffuse to the support structure, significantly extending the equipment life and reducing the failure frequency. At the same time, the design of the elastic module also improves the uniformity of the movement of the vibrating plate 20, so that the material is evenly distributed during the screening process, avoiding local overload or screen breakage. In addition, this connection method simplifies the tuning and compatibility of the device. Operators can adjust the spring stiffness to adapt to different material characteristics, enhancing the adaptability of the device in fine operations such as food grading or granule screening.
[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Below the first fixed ring 14, a second fixed ring 19 is provided. The first fixed ring 14 is fixedly connected to the second fixed ring 19 through the second support frame 15. Several casters 16 are provided below the second fixed ring 19. The first fixed ring 14 and the second fixed ring 19 are fixedly connected through the second support frame 15, forming a stable support frame that provides a reliable foundation for the vibration module. This ensures that the energy generated by the vibration plate 20 during vibration is effectively isolated and prevented from being transmitted to the external environment or the ground, thereby improving operational safety and equipment stability. At the same time, the casters 16 below the second fixed ring 19 give the device high mobility, allowing operators to easily move the entire filter device 1 to adapt to different workplaces or production line layouts, avoiding the constraints of fixed installation and relocation costs. This support structure also works in conjunction with the vibration spring 12 to further optimize the vibration absorption effect, making it suitable for scenarios with frequent changes in location, such as temporary construction sites or flexible production lines.
[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4A filter screen trough 17 is provided on the left side of the second fixing ring 19, and a waste screen trough 18 is provided on the right side of the second fixing ring 19. The filter screen trough 17 and the waste screen trough 18 are respectively located on the left and right sides of the second fixing ring 19, realizing independent storage and automatic classification of new and old filter screens. This simplifies material management for operators during the replacement process and avoids the problem of filter screens being scattered or mixed in traditional equipment. It ensures that waste screens can be directly recycled to the waste screen trough 18, and new screens are taken from the filter screen trough 17, improving the orderliness and efficiency of the workflow. At the same time, the dual-trough design also reduces the risk of cross-contamination of contaminants. Especially in applications with high cleanliness requirements such as the pharmaceutical or food industries, it can maintain environmental hygiene and material purity. In addition, the combination of this structure with the casters 16 and the second support frame 15 provides overall coordination for the device, supports rapid maintenance and recycling, and enhances the sustainability and economic advantages of the device.
[0031] The implementation principle of this embodiment is as follows: The operator drives the cylinder 203 through the lifting mechanism 2, so that the moving plate 201 drives the telescopic rod 202 to move the cover 3, exposing the filter screen 9 covering the vibrating plate 20. The roller motor 7 starts, driving the first roller 6 to recycle the dirty filter screen, while the second roller 61 releases the new filter screen. The two rotate synchronously on the first support frame 5 through the bearing seat 8. The old filter screen is rolled into the waste screen trough 18 on the right side, and the new filter screen is laid flat on the surface of the vibrating plate 20. The cylinder 203 moves in the opposite direction, pushing the movable cover 3 down to press the new filter screen. The vibrating motor 13 starts, driving the vibrating plate 20 to generate regular vibration. The vibration energy is transmitted to the first fixed ring 14 through the vibration spring 12, while the base formed by the second fixed ring 19 and the second support frame 15 achieves vibration isolation through the universal wheel 16. The material is layered on the vibrating filter screen. Fine material passes through the screen and falls into the collection trough 10 and is discharged from the discharge port 11. Coarse material is transported along the screen surface to the end collection.
