Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a plate and frame filter press with an independently driven filter cloth. Background Technology

[0002] Plate and frame filter presses feature a modular design, offering excellent sealing, high-efficiency filtration, ease of operation, and strong adaptability. They are widely used in various industries, including chemical, pharmaceutical, food, environmental protection, mining, metallurgy, ceramics, textile, papermaking, and petroleum. Currently, there are two main types of equipment: ordinary plate and frame filter presses and fully automatic intelligent plate and frame filter presses. Ordinary plate and frame filter presses have lower initial equipment costs but higher operating costs and require significant labor. Fully automatic intelligent plate and frame filter presses achieve truly automated operation, requiring no manual intervention and automatically completing processes such as feeding, unloading, and filter cloth cleaning.

[0003] Currently, fully automatic intelligent plate and frame filter presses use a shaft-driven method to move the filter cloth automatically. During use, the drive shaft requires regular maintenance, otherwise it is prone to breakage. Because the drive shaft cannot move, replacing the filter cloth is inconvenient. Therefore, this paper proposes a plate and frame filter press with an independent module driving the filter cloth movement. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a plate and frame filter press with an independently driven filter cloth mechanism. This solves the problems of easy breakage of the transmission system and inconvenience in filter cloth replacement in existing fully automatic intelligent plate and frame filter presses.

The independently driven module is mounted on a bracket at the top of the mounting plate, facilitating independent installation of each filter plate without interfering with the filter cloth suspension assembly, thus simplifying filter cloth replacement and improving the ease of installation and maintenance of the plate and frame filter press. Furthermore, the independently driven module, in conjunction with a closed-loop control algorithm based on pressure sensor feedback, dynamically adjusts the filter cloth tension, effectively avoiding the risk of filter cloth tearing and extending the filter cloth's service life.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4This utility model provides a technical solution: a plate and frame filter press with independently driven filter cloth, including a frame 1, mounting plates 2, a linear motor 3, push-pull blocks 4, and a filter cloth walking system 5. Several mounting plates 2 are fixedly connected to the surface of the frame 1 from left to right. Supports 6 are fixedly connected to the upper end of each mounting plate 2. The filter cloth walking system 5 includes an independently driven module 7, a filter cloth 8, a drive sprocket 9, a driven sprocket 10, a chain 11, and a drive shaft 12. The independently driven module 7 is fixedly connected to the outer wall of the support 6. Wheel 9 is located on the inner wall of bracket 6 and is fixedly connected to the output end of independent drive module 7. One end of drive shaft 12 is fixedly connected to the center of drive sprocket 9, and the other end of drive shaft 12 is fixedly mounted with driven sprocket 10. Chain 11 covers the surfaces of drive sprocket 9 and driven sprocket 10 respectively. Both ends of filter cloth 8 are connected to both ends of chain 11 respectively. Linear motor 3 and push-pull block 4 are fixedly mounted on the right end of frame 1. Linear motor 3 is fixedly connected to the side wall of frame 1, and push-pull block 4 is located on the surface of frame 1 and connected to linear motor 3.

[0024] In a further improvement, the independent drive module 7 adopts an electric drive mode and is connected to the main control system of the press, which facilitates overall control during the operation of the plate and frame filter press and improves the stability of operation.

[0025] In a further improvement, the independent drive module 7 consists of a servo motor 13 and a reducer 14. The output end of the servo motor 13 is connected to the input end of the reducer 14, and the output end of the reducer 14 is connected to the drive sprocket 9. By using the servo motor 13 and the reducer 14 to form the independent drive module 7, it is convenient to drive a single filter cloth 8 independently, and it is easy to adjust the movement speed and surface tension of the filter cloth 8.

[0026] In a further improvement, a hanging rod 15 is provided at the connection between the filter cloth 8 and the chain 11. A hanging ear 16 is fixedly connected to the surface of the hanging rod 15. The hanging ear 16 is rotatably connected to the chain 11. By providing a hanging ear 16 on the surface of the hanging rod 15, it is convenient to install it in conjunction with the chain 11. At the same time, the hanging rod 15 can fix the filter cloth 8 and avoid damage to the filter cloth 8.

[0027] In a further improvement, a limiting block 17 is fixedly connected to the side wall of the mounting plate 2. The limiting block 17 has a guide hole 18 in its center. By fixing the limiting block 17 with the guide hole 18 to the side wall of the mounting plate 2, it is convenient to effectively limit the installation of several mounting plates 2 during installation, thereby improving the consistency of the installation of the mounting plates 2.

[0028] In a further improvement, a slider 19 is fixedly connected to the lower surface of the limiting block 17, and a groove 20 is provided on the lower surface of the slider 19. By providing a slider 19 with a groove 20 on the lower surface of the limiting block 17, it is convenient to push and pull during the operation of the plate and frame filter press, thereby improving the stability of the plate and frame filter press operation.

[0029] Specifically, the side wall of the bracket 6 is also provided with a rotatably connected support wheel 21, and the chain 11 covers the surface of the support wheel 21. By providing a rotatably connected support wheel 21 on the side wall of the bracket 6, the chain 11 can be easily supported, and the chain 11 can be prevented from sticking to the surface of the mounting plate 2 and causing wear and scratches.

[0030] In this invention, during the pressing process in a filter press, the push-pull block 4 drives the mounting plate 2 to press against each other. Upon completion of pressing and the start of unloading, the control system directly outputs commands to each independent drive module 7, simultaneously driving the drive sprocket 9 to rotate. This, in turn, drives the transmission shaft 12 and the driven sprocket 10 to rotate clockwise. Due to the connection of the chain 11, all the filter cloths 8 begin to move downwards, causing the filter cake to actively separate from the filter cloths 8. After reaching the set stroke, the independent drive module 7 simultaneously starts driving the drive sprocket 9 to rotate counterclockwise, causing all the filter cloths 8 to move upwards. This completes one cycle of filter cloth 8 movement.

[0031] This invention solves the problem that current fully automatic intelligent plate and frame filter presses use a shaft-driven method to move the filter cloth automatically. During use, the drive shaft must be regularly maintained, otherwise it is prone to breakage. Because the drive shaft cannot move, it is inconvenient to replace the filter cloth. This invention replaces the traditional guide rod mechanical transmission with an independent drive module 7 on the mounting plate 2, completely eliminating the need for regular lubrication and calibration of the guide rod structure. The independent drive module 7 is installed on the bracket 6 at the top of the mounting plate 2, which facilitates the independent installation of each filter plate and does not interfere with the filter cloth 8 suspension assembly, making it easy to replace the filter cloth 8 and improving the ease of installation and maintenance of the plate and frame filter press. The independent drive module 7, in conjunction with a closed-loop control algorithm based on pressure sensor feedback, dynamically adjusts the tension of the filter cloth 8, effectively avoiding the risk of tearing the filter cloth 8 and extending its service life.
