Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a filter press filter plate moving device. Background Technology

[0002] In the routine production operation of a filter press, the reciprocating movement of the filter plates has a decisive impact on the equipment performance. The currently widely used slider-type moving mechanism has revealed a series of technical defects in actual operation. The direct contact between the slider and the guide rail significantly increases the motion resistance, causing not only sluggish filter plate movement but also increased energy consumption in the drive system. Simultaneously, it is accompanied by continuous high-decibel noise, severely interfering with the operating environment and threatening the health of workers. To alleviate friction problems, existing technologies rely on manual periodic lubrication, a cumbersome and time-consuming process that significantly increases maintenance manpower and material consumption costs. Furthermore, the oil sludge generated during lubrication easily spreads to the surrounding area, causing environmental degradation and hindering cleaning. Increased workload and untimely or uneven lubrication can directly lead to fluctuations in equipment operation and even unexpected shutdowns. In addition, the traditional slider structure wears out quickly during long-term reciprocating motion, and the accumulation of material fatigue significantly shortens its service life. Frequent replacement of parts not only interrupts the production process but also further increases the overall operating cost of the equipment. These combined problems seriously restrict the continuous and stable operation and long-term reliability of the filter press. In response to the above-mentioned problems in the existing technology, this utility model provides a filter plate moving device for a filter press, which aims to reduce the frictional resistance, maintenance costs, and noise pollution generated during the movement of the filter plates by optimizing the structure of the moving device, thereby improving the stability and operating efficiency of the equipment. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a filter plate moving device for a filter press, including a filter plate, a connecting component and a moving component. The moving component adopts a roller and limiting slide design. The roller rolls on the slide to achieve smooth movement of the filter plate, thereby effectively reducing the frictional resistance when the filter plate moves, reducing noise and extending the service life of the equipment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a filter plate moving device for a filter press, comprising a filter plate, a connecting assembly, and a moving assembly. The filter plate is provided with a connecting assembly and a moving assembly on both side walls along its length. The connecting assembly is horizontally positioned at a distance of one-quarter from the top of the filter plate. The end of the connecting assembly along its length is fixedly connected to the filter plate. The moving assembly is installed near the free end of the connecting assembly to facilitate the moving assembly in moving the filter plate. The moving assembly includes a roller and a limiting slide. The roller is securely mounted on the connecting assembly. The limiting slide is horizontally mounted on the top of the main beam at the end of the filter plate. The roller is mounted on the limiting slide to facilitate the roller rolling along the limiting slide.

[0005] Preferably, the connecting assembly includes a first connecting part, a second connecting part, and a chain. The second connecting part is fastened to the end of the first connecting part along its length direction. The end of the first connecting part away from the second connecting part is fastened to the filter plate. The chain is connected to the second connecting part.

[0006] Preferably, the second connecting part has a square structure and a connecting hole. The size of the connecting hole matches the chain 6, which facilitates the chain to pass through the connecting hole and connect multiple filter plates in series.

[0007] Preferably, the second connecting part includes a connector and a first limiting member. The first limiting member is detachably installed at the end of the connector to prevent the chain from slipping out. The shape of the connector matches the chain, making it easy for the chain to be sleeved on the connector. The end of the connector away from the first limiting member is connected to the first connecting part.

[0008] Preferably, the roller is installed at the first connecting part near the second connecting part, and the roller and the first connecting part are axially positioned by an interference fit.

[0009] Preferably, the roller uses a maintenance-free bearing.

[0010] Preferably, the cross-section of the limiting slide is a groove structure to facilitate the reciprocating movement of the roller along the limiting slide, and the two ends of the limiting slide along the length direction are provided with second limiting members to limit the rolling distance of the roller.

[0011] This utility model has the following advantages compared with the prior art:

[0012] 1. The filter plate moving device of this utility model includes a filter plate, a connecting component and a moving component. The moving component adopts a roller and limiting slide design. The filter plate moves smoothly by the roller rolling on the slide, thereby effectively reducing the frictional resistance when the filter plate moves, reducing noise and extending the service life of the equipment.

[0022] 4—First connecting plate; 5—Second connecting plate; 6—Chain. Detailed Implementation

[0023] like Figures 1 to 3 As shown, this utility model discloses a filter plate moving device for a filter press, including a filter plate 1, a connecting assembly, and a moving assembly. The filter plate 1 has a connecting assembly and a moving assembly on both side walls along its length. The connecting assembly is horizontally positioned at a quarter-th of the distance from the top of the filter plate 1. The end of the connecting assembly along its length is fixedly connected to the filter plate 1. The moving assembly is installed near the free end of the connecting assembly to facilitate the moving assembly in moving the filter plate 1. The moving assembly includes a roller 2 and a limiting slide 3. The roller 2 is fastened to the connecting assembly. The limiting slide 3 is horizontally installed on the top of the main beam at the end of the filter plate 1. The roller 2 is mounted on the limiting slide 3 to facilitate the roller 2 rolling along the limiting slide 3.

[0024] Specifically, two connecting components and two moving components are symmetrically arranged on both sides of the filter plate 1. There are multiple filter plates 1. Each filter plate 1 has connecting components and moving components on both ends of its length direction, providing uniform support and drive to ensure the balance and stability of the filter plate 1 during movement. The connecting components are fixed to the side wall of the filter plate 1 with their center line located at one-quarter of the distance from the top of the filter plate 1, so that the connecting components are firmly connected to the filter plate 1, which facilitates the reliable transmission of the push and pull force generated by the moving components and prevents relative displacement or loosening during movement. The moving components are installed near the free end of the connecting components, so that the moving components can effectively drive the filter plate 1 to move. The moving components include rollers 2 and limiting slides 3. The rollers 2 are mounted on the limiting slides 3. The main beam provides a solid installation foundation for the limiting slides 3, which facilitates the smooth rolling of the rollers 2 along the limiting slides 3, realizing the smooth and low-resistance movement of the filter plate 1, effectively reducing the frictional resistance generated during the reciprocating motion of the filter plate 1 and reducing operating noise.

[0025] The connecting assembly includes a first connecting part 4, a second connecting part 5, and a chain 6. The second connecting part 5 is fastened to the end of the first connecting part 4 along its length. The end of the first connecting part 4 away from the second connecting part 5 is fastened to the filter plate 1. The chain 6 is connected to the second connecting part 5.

[0026] Specifically, the first connecting part 4 is connected to the second connecting part 5 and the filter plate 1 at both ends along its length. The chain 6 is movably connected to the second connecting part 5, which facilitates the series connection of multiple filter plates 1, ensuring that each filter plate 1 can move synchronously and in a coordinated manner when the filter press is working. The first connecting part 4 is fastened to the filter plate 1, and the second connecting part 5 is fastened to the end of the first connecting part 4. This not only extends the connection point but also helps to disperse the stress transmitted by the chain 6, avoiding local stress concentration. The connection between the chain 6 and the second connecting part 5 ensures the synchronicity of multiple filter plates 1 during movement, preventing relative displacement between filter plates 1 due to unstable connection. The layered and tight connection method enhances the overall stability of the connecting components, effectively reducing the frictional resistance, noise, and wear generated by the filter plates 1 during movement, reducing maintenance requirements, and improving the operational reliability and efficiency of the filter press.

[0027] The second connecting part 5 has a square structure and a connecting hole. The size of the connecting hole matches the chain 6, so that the chain 6 can pass through the connecting hole to connect multiple filter plates 1 in series.

[0028] Specifically, the second connecting part 5 is a square plate with a connecting hole in the center. This connecting hole is used for the chain 6 to pass through and connect. The shape of the connecting hole can be circular, elliptical, or rectangular. The size of the connecting hole matches the width, pitch, or pin diameter of the chain 6 to ensure that the chain 6 can pass through smoothly and achieve a reliable connection. For example, the connecting hole can be a circular hole with a diameter slightly larger than the pin diameter of the chain 6 to facilitate the installation and removal of the chain 6. The chain 6 passes through the connecting hole on the second connecting part 5, connecting multiple filter plates 1 sequentially to form a continuous filter plate string. This series connection allows all filter plates 1 to move... Maintaining synchronized movement throughout the process ensures overall coordination and stability. The chain 6 can be a lifting chain, roller chain, sleeve chain, or plate chain, etc. It is directly connected through the connecting holes, which provides a more stable connection compared to hooks or clamps. This effectively prevents the chain 6 from falling off under stress or vibration, improving the operational reliability of the device. The chain 6 connects multiple filter plates 1 in series through the connecting holes, ensuring that each filter plate 1 is subjected to uniform force during movement. This reduces local stress concentration and wear, solves the problem of easy wear, extends the service life of the device, and improves the overall operational reliability and maintenance convenience of the filter plate moving device of the filter press.

[0029] The second connecting part 5 includes a connector and a first limiting member. The first limiting member is detachably installed at the end of the connector to prevent the chain 6 from slipping out. The shape of the connector matches the chain 6 so that the chain 6 can be sleeved on the connector. The end of the connector away from the first limiting member is connected to the first connecting part 4.

[0030] Specifically, the connector is responsible for connecting to the chain 6, while the first limiting member focuses on axially limiting the chain 6. The first limiting member is detachably installed at the end of the connector, allowing for a non-permanent connection between the first limiting member and the connector, such as snap-fit, pin, groove fit, wedge locking, or threaded engagement. This simplifies the installation, replacement, and daily maintenance process of the chain 6. When the chain 6 needs inspection or replacement, only the first limiting member needs to be removed, eliminating the need for large-scale disassembly of the entire connecting assembly, thus shortening maintenance time and reducing maintenance costs. The shape of the connector matches the chain 6, and the connector is matched according to the size of the connecting ring of the chain 6, ensuring that the chain 6 does not shift after being fitted onto the connector, or a rubber pad is laid circumferentially at the contact area between the chain 6 and the connector to prevent the chain 6 from shifting. The first limiting member, installed after the connector, prevents the chain 6 from slipping out of the connector.

[0031] Furthermore, the connector is a cylindrical structure, and the inner diameter of the first limiting member is the same as the outer diameter of the connector, so that the first limiting member can be engaged with the connector. The chain 6 wraps around the connector once, and the first limiting member is located outside the chain 6 to prevent the chain 6 from slipping out of the connector.

[0032] The roller 2 is installed at the first connecting part 4 near the second connecting part 5, and the roller 2 and the first connecting part 4 are axially positioned by an interference fit.

[0033] Specifically, the roller 2 and the first connecting part 4 are connected by an interference fit for axial positioning, which ensures the stability of the roller 2 in both the radial and axial directions, and makes the roller 2 and the first connecting part 4 tightly connected. The axial positioning prevents the roller 2 from shifting in the axial direction, eliminating the relative movement between the roller 2 and the first connecting part 4. For example, the roller 2 and the first connecting part 4 are forced to fit by heating the roller 2, cooling the first connecting part 4, or applying pressure. At the same time, retaining rings, washers, or shoulders are set on both sides of the roller 2 and fixed by bolts, snap rings, or welding to achieve axial positioning. The roller 2 is installed on the first connecting part 4 near the second connecting part 5, so that the force point of the roller 2 is closer to the connection center of the connecting assembly and the chain 6, which effectively shortens the lever arm and reduces the torque and vibration caused by the excessive lever arm when the filter plate 1 moves.

[0034] The roller 2 uses a maintenance-free bearing.

[0035] Specifically, roller 2 uses maintenance-free bearings, which effectively solves the problems of rollers requiring regular manual lubrication, high maintenance costs, high noise, and easy wear in the existing technology.

[0036] The limiting slide 3 has a groove structure in its cross section to facilitate the reciprocating motion of the roller 2 along the limiting slide 3. The limiting slide 3 is provided with second limiting members at both ends along its length to limit the rolling distance of the roller 2.

[0037] Specifically, the cross-section of the limiting slide 3 is designed as a groove structure, which provides precise guidance and stable support for the roller 2 mounted on it. This groove structure effectively constrains the lateral movement of the roller 2, preventing it from deviating from the track or wobbling during reciprocating motion, thereby significantly reducing the frictional resistance between the roller 2 and the limiting slide 3 and reducing operating noise. At the same time, the groove structure ensures that the roller 2 can move smoothly back and forth along the limiting slide 3 in a pure rolling manner, improving the smoothness and efficiency of the filter plate 1 movement. In addition, second limiting plates are set at both ends of the limiting slide 3 along its length to provide support for the rollers. The rolling distance of roller 2 provides a clear physical boundary. The second limiting plate can precisely limit the maximum movement range of roller 2, effectively preventing the filter plate 1 from exceeding the preset position during movement, thereby preventing collisions between equipment components, reducing unnecessary wear, and ensuring the stable operation and safe operation of the filter press. For example, the second limiting component can be a metal plate fixedly welded to the end of the limiting slide 3, and the height and strength of the metal plate are sufficient to withstand the impact of roller 2. Alternatively, the second limiting component can also be an adjustable bolt or stop, and the rolling distance of roller 2 can be precisely set by adjusting the position of the bolt or stop.

[0038] When the filter press needs to be opened, the drive mechanism starts, driving the filter plate 1 group to move via the chain 6. At this time, the roller 2 rolls on the limiting slide 3, separating the filter plate 1 from the pressed state or pressing it from the separated state. Compared with the sliding friction movement method used in the prior art, the rolling friction of the roller 2 significantly reduces the resistance when the filter plate 1 moves, thereby reducing the power consumption required by the drive mechanism. At the same time, the noise generated by rolling friction is much lower than that of sliding friction, improving the working environment. The cross-section of the limiting slide 3 is designed as a groove structure. This structure can effectively constrain the lateral movement of the roller 2, ensuring that the roller 2 always runs on the correct track and preventing it from derailing, thereby ensuring the accuracy and stability of the reciprocating motion of the filter plate 1. In addition, the limiting slide 3 is also provided with second limiting plates at both ends along the length direction. The second limiting plates can accurately limit the rolling distance of the roller 2, thereby controlling the movement stroke of the filter plate 1 and avoiding the filter plate 1 moving too far or too little, ensuring the accuracy of unloading or pressing operations.

[0039] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
