Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction technology, and in particular to a plate and frame filter press for sludge dewatering. Background Technology

[0002] Sludge dewatering is a process that removes a large amount of water from sludge through physical and chemical methods, reducing the sludge volume and moisture content to facilitate subsequent treatment, transportation, and disposal. Plate and frame filter presses are chosen for sludge dewatering because they utilize alternating plates and frames to form filter chambers, effectively achieving solid-liquid separation through mechanical extrusion. They offer advantages such as high processing capacity, wide adaptability, and low filter cake moisture content, significantly improving sludge dewatering efficiency and quality, reducing sludge disposal costs and environmental impact, and playing a crucial role in sludge treatment.

[0003] A plate and frame filter press for sludge dewatering mainly consists of a frame, a filtration mechanism, and a hydraulic system. The frame, serving as the supporting structure, is typically welded from structural steel, ensuring stability and reliability. The filtration mechanism, the core component, comprises several alternating plates and frames with filter cloth sandwiched between them for solid-liquid separation. The hydraulic system provides power to the filtration process, driving piston rods to press the plates and frames together, thus dewatering the sludge under pressure. Additionally, auxiliary components such as a feeding device and a filtrate collection device are included to ensure efficient and stable operation of the entire dewatering process.

[0004] In existing technologies, some plate and frame filter presses for sludge dewatering require manual cleaning of the filter plates. This is not only inefficient and time-consuming, significantly increasing labor costs, but also poses safety hazards. Therefore, a plate and frame filter press for sludge dewatering is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a plate and frame filter press for sludge dewatering, comprising a base plate 1, which serves as the foundation and supports the entire device. Sliding grooves 2 are fixedly connected to both the front and rear sides of the base plate 1, allowing sliding components on the device to slide within these grooves. Sliding plates 3 are slidably connected to the tops of both sliding grooves 2, moving the entire cleaning assembly. Fixed plates 4 are fixedly connected to the tops of both sliding plates 3, and support plates 5 are fixedly connected to adjacent sides of the two fixed plates 4. A second fixed plate 6 is fixedly connected inside the support plate 5. The fixed plates 4 transmit the moving force. The cleaning component is supported by a support plate 5. A fixed plate 6 protects the cleaning component. A motor 7 is slidably connected to the right side of the fixed plate 6. A rotating rod 8 is fixedly connected to the drive end of the motor 7. A rotating plate 9 is rotatably connected to the outside of the rotating rod 8. The motor 7 is the driving source for the rotation of the cleaning component, causing the rotating rod 8 to rotate. The rotating plate 9 rotates under the action of the rotating rod 8. An electric push plate 10 is fixedly connected to the top of the support plate 5. A moving plate 11 is fixedly connected to the drive end of the electric push plate 10. The electric push plate 10 is the driving source for the movement of the cleaning component, causing the moving plate 11 to move. An adjustment component for adjusting the spray head angle is rotatably connected to the inner wall of the rotating plate 9.

[0033] Reference Figure 2 and Figure 4 The adjustment assembly includes a second rotating plate 12, the front of which is rotatably connected to the inner wall of a first rotating plate 9. A cylinder 13 is fixedly connected to the rear of the second rotating plate 12. The drive end of the cylinder 13 is fixedly connected to a third rotating plate 16. Multiple nozzles 17 are fixedly connected to the left side of the third rotating plate 16. The second rotating plate 12 converts the shaking generated by the cylinder 13 during the driving process into rotation, thereby stabilizing the cylinder 13. The third rotating plate 16 receives the driving force of the cylinder 13 and thus rotates. The nozzles 17 are fixed on the third rotating plate 16 and thus rotate together with the third rotating plate 16.

[0034] Reference Figures 1 to 3The bottom of the movable plate 11 is rotatably connected to the outside of the rotating rod 8. The outside of the movable plate 11 is slidably connected to the inside of the support plate 5. The outside of the movable plate 11 is also slidably connected to the inside of the fixed plate 6. The movable plate 11 receives power from the electric push plate 10, which drives the rotating rod 8 to move. The front side of the rotating plate 9 contacts the inside of the fixed plate 6 under the rotation of the rotating rod 8. The rotating rod 8 protects the rotating plate 9 inside the fixed plate 6. The right side of the fixed plate 6 is slidably connected to the fixed plate 22. The top of the fixed plate 22 is fixedly connected to the bottom of the motor 7. The fixed plate 22 allows the motor to move stably and transmit power stably. The top of the bottom plate 1 is fixedly connected to the hydraulic motor 19, which moves the filter plate. The outside of the sliding groove 2 is fixedly connected to the protective cover 18. The protective cover 18 protects the internal separation components and stabilizes them. A pressure sensor 21 is fixedly connected to the top of the hydraulic motor 19. A long plate is fixedly connected to the left side of the base plate 1, and a pressure gauge 20 is fixedly connected to the left side of the long plate. The pressure sensor 21 receives the pressure from the hydraulic motor 19 and the mud press motor, and transmits it to the pressure gauge 20. The pressure gauge 20 has a PLC value. When the pressure reaches the threshold, it stops the equipment and automatically maintains the pressure. The long plate supports the base plate 1 and stabilizes it. A rotating rod 15 is rotatably connected to the inner wall of the rotating plate 1 9. The outside of the rotating rod 15 is fixedly connected to the inside of the rotating plate 2 16. The rotating rod 15 receives the rotational force of the rotating plate 2 16 and moves within the rotating plate 1 9. Two fixed plates 3 14 are fixedly connected inside the rotating rod 1 9. The fixed plates 3 14 stabilize the rotation of the rotating plate 2 12.

[0035] Working principle: The equipment moves the sliding plate 3, which in turn moves the support plate 5, moving the filter plate into the support plate 5. Then, the motor rotates the rotating rod 8, which in turn rotates the nozzle 17 on the rotating plate 9, so that the nozzle 17 faces the filter plate. At this time, the electric push plate 10 moves the moving plate 11, which in turn moves the rotating rod 8, so that the nozzle 17 moves to clean the filter plate. This achieves the cleaning of the filter plate. In addition, timely cleaning of the filter plate can prevent the filter holes from clogging, maintain the smooth passage of filtrate, and thus ensure efficient sludge dewatering, improving the dewatering effect and the quality of the finished product.

[0036] When the nozzle 17 moves, the cylinder 13 inside the rotating plate applies force, which in turn applies force to the rotating plate 16, causing the rotating plate 16 to deflect. This allows the nozzle 17 on the rotating plate 16 to adjust its angle, thus enabling the nozzle 17 to adjust its angle during cleaning. In addition, it can cover all corners and complex structures of the filter plate, washing away residual sludge without dead angles, thereby thoroughly removing stubborn stains and ensuring cleaning effect.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
