Description

Technical Field

[0001] This utility model belongs to the field of filter plate technology for filter presses, and particularly relates to the structure of press filter plates for filter presses. Background Technology

[0002] In the field of industrial solid-liquid separation, filter presses are widely used as core equipment in industries such as chemical, environmental protection, and food. The press plate structure of a filter press is a key component for achieving efficient solid-liquid separation, and its performance directly affects the filter press's filtration efficiency, energy consumption, and equipment lifespan. With the expansion of industrial production scale and the increasing demands for separation precision, higher requirements are placed on the stability, pressure resistance, and reliability of the press plate structure. Designing a more rational press plate structure can effectively improve filtration efficiency and reduce equipment maintenance costs, which is of great significance for promoting the high efficiency and sustainable development of industrial production.

[0003] Existing filter presses typically employ rigid connections for their filter plates, with direct contact between the plates and between the plates and the frame via rigid materials. During filtration and pressing, a hydraulic system drives the filter plate assembly to close rapidly, or a high-pressure medium squeezes the filter cake, generating impact forces that act directly on the filter plates. The underlying technology relies primarily on the rigidity of the filter plates themselves to resist pressure, a simple sealing structure to prevent filtrate leakage, and filter cloth to intercept solid particles, achieving solid-liquid separation.

[0004] However, this traditional rigid structure is prone to rigid impact on the filter plates under high pressure conditions. After long-term operation, cracks and damage easily occur at the edges and sealing surfaces of the filter plates, which not only leads to filtrate leakage and affects the separation effect, but also increases equipment maintenance costs due to frequent filter plate replacements. At the same time, strong vibrations can loosen the filter plate connecting parts, reducing the stability of equipment operation. Therefore, a press filter plate structure for filter presses is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a pressing filter plate structure for a filter press, which aims to solve the technical problems of filter plate cracking, sealing surface damage and equipment vibration caused by rigid impact under high pressure working conditions in existing filter presses.

[0006] The technical solution of this utility model is implemented as follows: a filter plate structure for a filter press includes a filter frame, a filter plate body is fixedly connected inside the filter frame, a buffer component is provided on the side wall of the filter frame, and vibration components are provided on both sides of the filter frame.

[0007] The buffer assembly includes a damper. A fixed frame is fixedly connected inside the filter frame. A mounting bracket is provided on the side wall of the fixed frame. The damper is fixedly installed between the fixed frame and the mounting bracket. A fixed rod is fixedly connected inside the fixed frame. A slider is provided between the fixed rod and the side wall of the mounting bracket. One side of the slider is slidably connected to the side wall of the fixed rod, and the other side of the slider is fixedly connected to the side wall of the mounting bracket. A rotating rod is rotatably connected between the sliders. A first spring is sleeved on the side wall of the fixed rod. A telescopic rod is fixedly connected between the fixed frame and the mounting bracket. A second spring is sleeved on the side wall of the telescopic rod.

[0008] Optionally, the vibration assembly includes an eccentric wheel, and a fixing frame is fixedly connected to both sides of the filter frame, with the sidewall of the eccentric wheel rotatably connected to the sidewall of the fixing frame.

[0009] Optionally, a fixing block is fixedly connected to the side wall of the fixing frame, a connecting rod is fixedly connected to the side wall of the eccentric wheel, and a connecting column is rotatably connected to the side wall of the connecting rod.

[0010] Optionally, the sidewall of the connecting column is slidably connected inside the fixing block, and a fixing plate is fixedly connected to the sidewall of the connecting column.

[0011] Optionally, a rubber block is fixedly connected to the side wall of the fixing plate, and the side wall of the rubber block strikes the side wall of the filter frame.

[0012] Optionally, a motor is fixedly connected to the side wall of the fixing frame, and the output end of the motor is connected to the eccentric wheel.

[0013] Optionally, one end of the first spring is fixedly connected inside the fixed frame, and the other end of the first spring is fixedly connected to the side wall of the slider.

[0014] Optionally, one end of the second spring is fixedly connected to the side wall of the fixed frame, and the other end of the second spring is fixedly connected to the side wall of the mounting bracket.

[0015] 1. In this utility model, when the filter frame is impacted, the impact force is transmitted to the mounting frame, causing it to displace. The connected slider drives the rotating rod to push the other end slider to slide along the fixed rod. During this process, the damper dissipates energy through fluid damping, the first spring is compressed and deformed to store energy, the telescopic rod restricts the displacement, and the second spring provides buffering force. The three work together to reduce the vibration and displacement of the filter frame, reduce the impact load, and solve the problems of filter plate cracking, sealing surface damage, and equipment vibration caused by rigid impact under high pressure working conditions. The above technical solution improves the stability and service life of the filter plate structure.

[0016] 2. In this utility model, the motor drives the eccentric wheel to rotate, and the eccentric structure generates centrifugal force. The connecting rod drives the connecting column to reciprocate within the fixed block, pushing the fixed plate and rubber block to strike the side wall of the filter frame. The rubber block assists in unloading with elastic vibration, preventing the filter cake from sticking. This solves the problems of difficult unloading and easy damage to the filter cloth caused by the high viscosity or low moisture content of the filter cake. The above technical solution improves the unloading efficiency.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please refer to Figures 1-3As shown in the figure, the filter plate structure for a filter press provided in this embodiment of the present invention includes a filter frame 1. The filter frame 1 is used to support and protect the filter plate body 2, and provides an installation base for the buffer assembly and vibration assembly, playing a role in fixing the position of each component and ensuring the overall stability of the filter plate structure. The filter plate body 2 is fixedly connected inside the filter frame 1. A buffer assembly is provided on the side wall of the filter frame 1, and vibration assemblies are provided on both sides of the filter frame 1. The buffer assembly includes a damper 5. A fixed frame 3 is fixedly connected inside the filter frame 1. A mounting frame 4 is provided on the side wall of the fixed frame 3. The damper 5 is fixedly installed between the fixed frame 3 and the mounting frame 4. A fixed rod 6 is fixedly connected inside the fixed frame 3. A slider 7 is provided on the side wall of the mounting frame 4 and the fixed rod 6. One slider 7 is slidably connected to the side wall of the fixed rod 6, and the other slider 7 is fixedly connected to the side wall of the mounting frame 4. A rotating rod 8 is rotatably connected between the sliders 7. The sliders 7 cooperate with the fixed rod 6 to slide. The sliders 7 can slide on the fixed rod 6, providing guidance for the movement of the mounting frame 4 and ensuring a smooth buffering process. A first spring 9 is sleeved on the side wall of the fixed rod 6. A telescopic rod 10 is fixedly connected between the fixed frame 3 and the mounting bracket 4. A second spring 11 is sleeved on the side wall of the telescopic rod 10. The telescopic rod 10 moves in conjunction with the second spring 11. When the mounting bracket 4 is impacted, the telescopic rod 10 limits the movement distance of the mounting bracket 4 to prevent excessive displacement. At the same time, the second spring 11 provides elastic buffering force. One end of the first spring 9 is fixedly connected to the inside of the fixed frame 3, and the other end of the first spring 9 is fixedly connected to the side wall of the slider 7. One end of the second spring 11 is fixedly connected to the side wall of the fixed frame 3, and the other end of the second spring 11 is fixedly connected to the side wall of the mounting bracket 4. The damper 5 moves in conjunction with the first spring 9 and the second spring 11 to buffer the movement. When the filter frame 1 is impacted, the damper 5 consumes energy through the damping effect of the internal fluid. The first spring 9 and the second spring 11 absorb and store energy through elastic deformation. The three work together to reduce the vibration and displacement of the filter frame 1, thereby reducing the impact load during equipment operation and extending the service life of the filter plate.

[0027] Reference Figure 1 , Figure 4 and Figure 5The vibration assembly includes an eccentric wheel 13, fixed frames 12 fixedly connected to both sides of the filter frame 1, a side wall of the eccentric wheel 13 rotatably connected to the side wall of the fixed frame 12, a fixed block 14 fixedly connected to the side wall of the fixed frame 12, a connecting rod 15 fixedly connected to the side wall of the eccentric wheel 13, a connecting column 16 rotatably connected to the side wall of the connecting rod 15, and a side wall of the connecting column 16 slidably connected inside the fixed block 14. The fixed block 14 provides a track for the sliding of the connecting column 16, so that the rotation of the eccentric wheel 13 can be stably converted into the linear reciprocating motion of the connecting column 16. A fixed plate 17 is fixedly connected to the side wall of the connecting column 16, and a rubber block 18 is fixedly connected to the side wall of the fixed plate 17. The side wall of block 18 strikes the side wall of filter frame 1. The rubber block 18 has a certain elasticity. When striking the filter frame 1, it can generate sufficient vibration effect while avoiding rigid damage to the filter frame 1. A motor 19 is fixedly connected to the side wall of the fixed frame 12. The output end of the motor 19 is connected to the eccentric wheel 13. The eccentric wheel 13, together with the connecting rod 15 and the connecting column 16, performs circular motion and then linear reciprocating motion. The motor 19 drives the eccentric wheel 13 to rotate. The eccentric wheel 13 drives the connecting column 16 to perform linear reciprocating motion within the fixed block 14 through the connecting rod 15, thereby causing the rubber block 18 to strike the side wall of the filter frame 1, achieving the effect of assisting unloading and preventing filter cake adhesion.

[0028] Working principle: When the filter frame 1 is impacted by the outside, the impact force is transmitted to the mounting frame 4, causing the mounting frame 4 to tend to displace. At this time, the slider 7 connected to the mounting frame 4 drives the rotating rod 8 to rotate, which pushes the slider 7 at the other end to slide along the fixed rod 6 to adapt to the change in the moving angle of the mounting frame 4. During this process, the damper 5 plays a role, consuming the impact energy through the damping effect of the internal fluid. At the same time, the first spring 9 undergoes elastic deformation when the slider 7 slides and squeezes, absorbing and storing some energy. Meanwhile, the telescopic rod 10 limits the movement range of the mounting frame 4 to prevent excessive displacement. The second spring 11 works with the telescopic rod 10 to provide elastic buffering force. The three work together to effectively dissipate the impact force on the filter frame 1, reduce the vibration amplitude and displacement of the filter frame 1, thereby reducing the impact load on the equipment during operation, protecting the filter plate structure, and extending the service life of the filter plate.

[0029] After the motor 19 starts, it drives the eccentric wheel 13 to rotate. The eccentric structure generates periodic centrifugal force. The eccentric wheel 13 drives the connecting column 16 to make linear reciprocating motion in the fixed block 14 through the connecting rod 15. The connecting column 16 pushes the fixed plate 17 and the rubber block 18, so that the rubber block 18 periodically hits the side wall of the filter frame 1. The elastic material of the rubber block 18 can generate a vibration effect while avoiding damage to the filter frame 1. Vibration assists in unloading and prevents the filter cake from sticking to the filter plate body 2.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
