Description

Technical Field

[0001] This utility model relates to the field of filter presses, specifically a modular frame type detachable filter press. Background Technology

[0002] Filter presses are key equipment for efficient solid-liquid separation driven by pressure. Their working principle involves a hydraulic system that compresses multiple layers of filter plates covered with filter cloth to form a filter chamber. The suspension is then pumped into the filter chamber under high pressure. Under pressure, the liquid passes through the filter cloth and is discharged, while solid particles are trapped to form a filter cake. Its core advantage lies in the secondary, powerful compression of the filter cake through mechanical pressing, significantly reducing the moisture content. The separation effect is far superior to other equipment such as centrifuges. This equipment boasts a high degree of automation and high filtrate clarity, making it suitable for processing highly viscous and fine-particle materials. It is widely used in various industries, including urban and industrial sludge dewatering, mine tailings treatment, chemical product separation, food and beverage clarification, pharmaceutical purification, and petrochemicals. Its most important application is in the deep dewatering of sludge in the environmental protection field.

[0003] In existing filter presses, raw materials are poured into the middle of the filter plates during operation. The filter plates are then crushed by a hydraulic mechanism. The liquid is collected at the collection point through the flow channel, and the solids formed after crushing adhere to the grooves of the filter plates. The solid blocks are then shaken off by pulling the filter plates one by one by a trolley. However, after long-term operation, pulling the trolley will cause wear on the sides of the filter plates that are being pulled. Since the filter plates are made of a single piece, it is not easy to replace them after damage. Therefore, the inventors urgently need to design a device that can quickly replace the worn parts to improve maintenance efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a modular frame-type detachable filter press to solve the technical problem of low maintenance efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular frame-type detachable filter press, comprising a filter press body, an mounting bracket on the top of the filter press body, a plurality of filter plates in the middle of the mounting bracket, connecting blocks on both sides of the filter plates, two pins at one end of the connecting blocks, and a locking mechanism sleeved on the outer side of the connecting blocks, the locking mechanism comprising a locking block body, a first groove inside the locking block body, and two pin holes on one side surface of the first groove, the pins being engaged with the inside of the pin holes.

[0006] By adopting the above technical solution, the modular frame detachable filter press significantly improves the ease of maintenance during long-term operation through the ingenious cooperation between the connecting blocks on both sides of the filter plate and the locking mechanism. This design allows the connecting blocks to be directly engaged in the pin holes of the locking block body through pins, forming a stable mechanical locking structure. This allows workers to quickly disassemble or install worn parts without tools, avoiding the problem of large-scale replacement when the entire filter plate of the traditional filter press is damaged. Maintenance is only required for key connection points, thereby reducing equipment downtime and enhancing production continuity.

[0007] Furthermore, two mounting slots are provided on both sides of the main body of the card block, and the mounting slots are rectangular in structure.

[0008] By adopting the above technical solution, the rectangular mounting groove provides a precise and efficient guiding path for the insertion of the limiting block, ensuring alignment during installation and reducing the risk of stress concentration in components due to improper assembly. This allows operators to complete rapid assembly without precision tools, significantly reducing the complexity of maintenance procedures, and is particularly effective in high-vibration environments.

[0009] Furthermore, a limiting block for the through-block body is installed inside the mounting groove. The limiting block has a T-shaped structure and is used to limit the position of the connecting block.

[0010] By adopting the above technical solution, the T-shaped limiting block added inside the installation groove completely solves the inherent defect of the connection block not being firmly positioned, and improves the structural integrity of the filter press under dynamic working conditions. The T-shaped structure design allows it to penetrate the main body of the locking block, and firmly restricts the lateral displacement of the connection block through geometric self-locking characteristics, preventing loosening or misalignment under high-frequency hydraulic impact. This constraint mechanism ensures the positional stability of the filter plate in repeated rolling cycles, thereby optimizing the liquid filtration efficiency and the solid block formation quality, and avoiding raw material leakage problems caused by connection point failure.

[0011] Furthermore, a fixing block is provided on one side of the main body of the card block, and a second groove is provided inside the fixing block, with one end of the limiting block being engaged in the middle of the second groove.

[0012] By adopting the above technical solution, the synergistic effect of the fixed block and the second groove significantly enhances the fixing reliability of the limiting block, solving the problem of easy loosening of traditional filter presses under impact loads. The nested structure formed by the fixed block and the second groove provides rigid support for one end of the limiting block, ensuring that it does not move axially during operation and maintaining the overall structural stability of the filter plate. This double snap-fit ​​mechanism can effectively absorb the high pressure energy applied by the hydraulic cylinder, preventing the connection mechanism from generating fatigue cracks in a high-frequency vibration environment, thereby improving the durability of the equipment under harsh working conditions.

[0013] Furthermore, the fixing block and the limiting block are connected by a first bolt threaded together.

[0014] By adopting the above technical solution, the setting of connecting the fixing block and the limiting block through the threaded connection of the first bolt provides an adjustable fastening solution for the entire locking mechanism, which greatly optimizes the maintenance efficiency and structural adaptability of the equipment. This threaded connection method allows maintenance personnel to flexibly adjust the fastening force according to the actual wear condition, ensuring that the optimal tightness is maintained during long-term operation, preventing component breakage due to excessive tightness or vibration dislocation caused by excessive looseness, avoiding irreversible effects caused by permanent welding or gluing, realizing non-destructive disassembly, simplifying the component replacement process and reducing resource waste.

[0015] Furthermore, silicone pads are threadedly connected to both sides of the main body of the card block via second bolts.

[0016] By adopting the above technical solution, the design of fixing the silicone pad to both sides of the main body of the card block with the second bolt greatly improves the vibration reduction and buffering capacity of the equipment, effectively alleviates the impact damage of the filter plate during operation, and the high elasticity of the silicone material can absorb the instantaneous impact force applied by the hydraulic mechanism and disperse it to a larger area, reducing the local wear of the contact points of the pin and the connecting block, thereby extending the service life of key components.

[0017] Furthermore, a drive mechanism is provided above the main body of the filter press, and the output end of the drive mechanism is connected to a hydraulic rod.

[0018] By adopting the above technical solution, the drive mechanism is connected to the hydraulic rod at the output end, which optimizes the power transmission efficiency and operating accuracy of the filter press, improves the overall filtration performance, and the hydraulic system can provide stable and continuous pressure output, ensuring that the filter plate is subjected to uniform force during the rolling process, thereby producing solid blocks of consistent size and reducing raw material waste. It avoids the complex transmission structure of mechanical linkages, simplifies the maintenance process, reduces the risk of failure, and improves the reliability of the system.

[0019] In summary, the present invention has the following main advantages: 1. This utility model solves the pain point of replacing the entire filter plate after both sides are worn by modular design of connecting block and locking mechanism. The locking mechanism of pin and pin hole realizes quick positioning, so that the disassembly and assembly of worn parts does not require professional tools, which greatly shortens the maintenance time. At the same time, the bolt-fixed limiting block and fixing block form a double lock to ensure the rigidity and stability of the connection structure under hydraulic working state, and avoid filter plate misalignment leading to leakage or failure. 2. This utility model significantly improves impact resistance through the combination of T-shaped limiting block and rectangular mounting groove. This geometric structure disperses the vibration load generated by the hydraulic mechanism and reduces stress concentration at the pin contact point. At the same time, the mounting groove provides effective buffer space for the silicone pad, extending the service life of key components. The pad is installed in an adjustable manner with bolts, allowing for real-time compensation of gaps according to wear conditions. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] In this embodiment: A modular frame type detachable filter press, such as Figure 1-7As shown, the filter press includes a filter press body 1, a mounting bracket 2 on top of the filter press body 1, several filter plates 5 in the middle of the mounting bracket 2, connecting blocks 501 on both sides of the filter plates 5, two pins 502 at one end of the connecting blocks 501, and a locking mechanism 6 sleeved on the outside of the connecting blocks 501. The locking mechanism 6 includes a locking block body 601, a first groove 602 inside the locking block body 601, and two pin holes 603 on one side surface of the first groove 602. The pins 502 are engaged with the inside of the pin holes 603. The modular frame type detachable filter press significantly improves the ease of maintenance during long-term operation through the ingenious cooperation between the connecting blocks on both sides of the filter plates and the locking mechanism. This design allows the connecting blocks to be directly engaged into the pin holes of the locking block body by the pins, forming a stable connection. The mechanical locking structure allows workers to quickly disassemble or install worn parts without tools, avoiding the problem of large-scale replacement required when the entire filter plate is damaged in traditional filter presses. Maintenance is only required at critical connection points, thereby reducing equipment downtime and enhancing production continuity. At the same time, the first groove provides sufficient internal space to ensure the accuracy and reliability of pin positioning, effectively absorbing the impact load generated during hydraulic operation and preventing accidental detachment. This modular structure also simplifies spare parts management, requiring the factory to stock only a small number of key components instead of entire filter plates, further optimizing supply chain management. In addition, the introduction of this locking mechanism strengthens the overall structural strength of the equipment, keeping the filter plates stable under high-pressure crushing conditions, extending equipment life and improving operational safety.

[0024] See Figure 3 , Figure 4 The main body 601 of the card block has two mounting slots 604 on both sides. The mounting slots 604 are rectangular in shape. The rectangular shape of the mounting slots provides a precise and efficient guide path for the insertion of the limiting block, ensuring alignment during installation and reducing the risk of stress concentration in components due to improper assembly. This allows operators to complete quick assembly without precision tools, significantly reducing the complexity of maintenance procedures. The effect is particularly prominent in high-vibration environments. At the same time, the dual setting of the mounting slots increases the redundancy of the mechanism. Even if one mounting slot is damaged, the rest can still maintain the normal operation of the system, avoiding the complete loss of the overall filter plate function. It also facilitates integration with other auxiliary components such as gaskets or buffer layers, enhancing the modular expansion capability of the system.

[0025] See Figure 3 , Figure 4The mounting groove 604 houses a T-shaped limiting block 605 that penetrates the main body 601 of the clamping block. This T-shaped limiting block restricts the position of the connecting block 501. The T-shaped limiting block inside the mounting groove completely solves the inherent defect of unstable positioning of the connecting block, improving the structural integrity of the filter press under dynamic operating conditions. The T-shaped design allows it to penetrate the main body of the clamping block and firmly restricts the lateral displacement of the connecting block through geometric self-locking characteristics, preventing loosening or misalignment under high-frequency hydraulic impact. This constraint mechanism ensures the positional stability of the filter plate during repeated rolling cycles, thereby optimizing liquid filtration efficiency and solid block formation quality, and avoiding raw material leakage caused by connection point failure. At the same time, the detachable feature of the limiting block, combined with the mounting groove, facilitates preventive maintenance of the equipment. Internal components can be inspected simply by removing the limiting block, without disassembling the entire machine, greatly shortening downtime response time. The symmetry of the T-shaped structure also balances the load distribution, reduces local wear, and extends the overall lifespan of the connecting mechanism.

[0026] See Figure 3 , Figure 4 , Figure 5 A fixing block 606 is provided on one side of the main body 601 of the locking block. A second groove 607 is provided inside the fixing block 606. One end of the limiting block 605 is locked into the middle of the second groove 607. The synergistic effect of the fixing block and the second groove significantly enhances the fixing reliability of the limiting block and solves the problem of easy loosening of traditional filter presses under impact load. The nested structure formed by the fixing block and the second groove provides rigid support for one end of the limiting block, ensuring that it does not move axially during operation and maintaining the overall structural stability of the filter plate. This double locking mechanism can effectively absorb the high pressure energy applied by the hydraulic cylinder and prevent the connection mechanism from generating fatigue cracks in the high-frequency vibration environment, thereby improving the durability of the equipment under harsh working conditions. At the same time, the design of the fixing block also facilitates linkage with the first bolt, simplifying the assembly process and allowing maintenance personnel to complete the tightening in a single operation without additional tools or complicated steps. The setting of the second groove not only enhances the mechanical locking effect, but also reserves space for other components such as sealing rings, achieving better sealing and anti-fouling ability and reducing the risk of lubricating oil leakage.

[0027] See Figure 3 , Figure 4 , Figure 5The fixing block 606 and the limiting block 605 are connected by a threaded first bolt 608. This threaded connection provides an adjustable fastening solution for the entire locking mechanism, significantly optimizing equipment maintenance efficiency and structural adaptability. This threaded connection allows maintenance personnel to flexibly adjust the tightening force according to actual wear conditions, ensuring optimal tightness during long-term operation. It prevents component breakage due to overtightening or vibration dislocation due to overloosening, avoids irreversible effects from permanent welding or gluing, achieves non-destructive disassembly, simplifies component replacement procedures, and reduces resource waste. At the same time, the standardized design of the bolt structure ensures the universality of spare parts, allowing factories to quickly replace them using conventional tools, reducing reliance on special tools and training costs. It is particularly suitable for multi-production line applications. The threaded connection also enhances the system's vibration resistance. Under high-frequency impact, the self-locking characteristics of the bolts prevent accidental loosening, ensuring the continuity of the filtration process and product qualification rate.

[0028] See Figure 3 , Figure 4 The two sides of the main body 601 of the clamping block are connected to silicone pads 609 by second bolts 610. The design of fixing the silicone pads to the two sides of the main body of the clamping block by the second bolts greatly improves the vibration damping and buffering capacity of the equipment, effectively alleviates the impact damage of the filter plate during operation. The high elasticity of the silicone material can absorb the instantaneous impact force applied by the hydraulic mechanism and distribute it to a larger area, reducing local wear at the contact points of the pins and connecting blocks, thereby extending the service life of key components. At the same time, the pads also reduce vibration and noise pollution, improve the safety of the operating environment and meet the environmental protection standards of modern factories. The installation and removal of the pads by the second bolt thread connection is simple and controllable. The staff can regularly inspect or replace the worn pad parts without stopping the entire production line, significantly reducing the impact of maintenance intervention on production capacity. This structure also provides an additional sealing layer to prevent the filter liquid or sludge from entering the internal connection mechanism and causing corrosion.

[0029] See Figure 1 , Figure 2A drive mechanism 4 is installed above the main body 1 of the filter press. The output end of the drive mechanism 4 is connected to a hydraulic rod 3. The connection between the output end of the drive mechanism and the hydraulic rod optimizes the power transmission efficiency and operating accuracy of the filter press, improves the overall filtration performance, and provides a stable and continuous pressure output. This ensures that the filter plates are subjected to uniform force during the crushing process, thereby producing solid blocks of consistent size and reducing raw material waste. It avoids the complex transmission structure of mechanical linkages, simplifies the maintenance process, reduces the risk of failure, and improves system reliability. At the same time, the direct connection between the output end of the drive mechanism and the hydraulic rod forms a closed energy transmission path, reducing power loss and improving energy utilization, especially in long-term operation. This structure allows for remote or automatic control of pressure parameters, making it easy to integrate into a smart factory system to achieve precise process control and improve product quality consistency.

[0030] The implementation principle of this embodiment is as follows: the main body 601 of the card block is installed on the connecting blocks 501 on both sides of the filter plate 5. The pin 502 will cooperate with the pin hole 603 to fix the position of the main body 601 of the card block. The T-shaped limiting block 605 is inserted in the middle of the two mounting slots 604. The fixing block 606 is installed on one end of the limiting block 605. The one end of the limiting block 605 is sleeved. Then the first bolt 608 is installed to fix the position of the limiting block 605 and the fixing block 606, further fixing the main body 601 of the card block. The silicone soft pad 609 is fixed by the second bolt 610 to reduce the wear of the position where the main body 601 of the card block is pulled.
