Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration equipment technology, and in particular to an ultrasonic cleaning disc self-cleaning filtration device. Background Technology
[0002] In industrial production and water treatment, disc filter self-cleaning devices are widely used due to their high efficiency, energy saving, and ease of maintenance. These filters typically consist of a series of annular discs with precisely designed micro-filtration channels between them, effectively intercepting impurities in the fluid and ensuring smooth production processes and clean water. The core advantage of disc filters lies in their self-cleaning function, which uses specific mechanical or hydraulic mechanisms to periodically remove dirt from between the discs, preventing clogging and maintaining stable filtration efficiency.
[0003] To further improve cleaning efficiency, the industry has begun to introduce ultrasonic cleaning technology into disc filter devices. Ultrasonic cleaning utilizes the vibration energy generated by high-frequency sound waves, which can penetrate the fluid-solid interface and generate strong microjets and shock waves. This effectively peels off and disperses dirt and impurities adhering to the surface of the discs, greatly improving the cleaning effect.
[0004] In existing devices, several filter elements are often pressed together to ensure filtration efficiency. During ultrasonic cleaning, a certain gap is required between the filter elements to facilitate the propagation of sound waves and the removal of dirt. However, since the force between the filter elements in existing devices cannot be adjusted, the dirt between the tightly fitted filter elements cannot be effectively cleaned.
[0005] Therefore, this application proposes an ultrasonic cleaning disc-type self-cleaning filter to solve the above problems. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-6 This utility model provides a technical solution: an ultrasonic cleaning disc-type self-cleaning filter device, including an outer filter cylinder 1 and an ultrasonic vibrating rod 12. The upper end of the outer filter cylinder 1 is open, and a bottom water inlet cylinder 2 is fixedly connected to the lower end of the filter cylinder. A water inlet pipe 3 is fixedly connected to the side wall of the bottom water inlet cylinder 2, and a sewage pipe 4 is fixedly connected to the lower end of the bottom water inlet cylinder 2. Both the sewage pipe 4 and the water inlet pipe 3 are connected to the bottom water inlet cylinder 2. An upper sealing cover 5 is provided above the outer filter cylinder 1, and an internal threaded connecting ring 24 is rotatably connected to the lower end of the upper sealing cover 5. The internal threaded connecting ring 24 is threadedly connected to the outer filter cylinder 1. A clamping mechanism is provided between the upper sealing cover 5 and the outer filter cylinder 1, and a partition is fixedly connected to the inner side wall of the upper sealing cover 5. The partition plate 17 has two water guide pipes 6 fixedly connected to the lower inner wall of the filter outer cylinder 1. Several water passage holes 7 are opened on the side wall of the water guide pipes 6. Two through holes 21 are opened on the partition plate 17. The upper end of the water guide pipe 6 passes through the through holes 21 and extends to the top of the partition plate 17. A sealing ring 22 is provided between the water guide pipe 6 and the inner side wall of the through hole 21. A water outlet pipe 10 is fixedly connected to the upper sealing cover 5. The water outlet pipe 10 communicates with the upper sealing cover 5. Several filter plates 8 are provided on the inner side of the filter outer cylinder 1. The filter plates 8 are annular. Both water guide pipes 6 are located inside the annular filter plates 8. The lower end of the ultrasonic vibrating rod 12 passes through the upper side wall of the upper sealing cover 5 and the partition plate 17 in sequence and extends to the inner side of the filter outer cylinder 1.
[0025] The pressing mechanism includes a movable plate 16 and a pressing plate 18, both of which are annular. Several support springs 23 are provided between the movable plate 16 and the pressing plate 18. The upper and lower ends of the support springs 23 are fixedly connected to the adjacent side walls of the movable plate 16 and the pressing plate 18, respectively. A sealing frame 19 is fixedly connected to the lower end of the pressing plate 18. The lower end of the sealing frame 19 abuts against the upper end of the uppermost filter element 8. The longitudinal outer side wall of the sealing frame 19 abuts against the inner side wall of the outer filter cylinder 1. Under the action of the pressing mechanism, the pressing plate 18 is guaranteed to press the several filter elements 8 at the lower end, thereby ensuring that the device can better filter sewage when in use.
[0026] The pressing mechanism also includes an adjusting motor 13, which is fixed to the upper end of the upper sealing cover 5. The output end of the upper sealing cover 5 is fixedly connected to an internal thread adjusting cylinder 14. The lower end of the internal thread adjusting cylinder 14 passes through the upper side wall of the upper sealing cover 5 and the partition plate 17 in sequence and extends to the top of the moving plate 16. The internal thread adjusting cylinder 14 is internally threadedly connected to an adjusting screw 15. The lower end of the adjusting screw 15 is fixedly connected to the upper end of the moving plate 16. The upper side wall of the upper sealing cover 5 and the partition plate 17 are rotatably connected to the internal thread adjusting cylinder 14. During filtration, the adjusting motor 13 drives the internal thread adjusting cylinder 14 to rotate, and then the adjusting screw 15 drives the moving plate 16 to move upward, thereby reducing the force of the pressing mechanism on the filter element 8. Then, through the action of the ultrasonic vibration rod 12, the dirt and impurities between the filter elements 8 can be cleaned more effectively.
[0027] A partition sleeve 20 is fixedly connected to the clamping plate 18. The partition sleeve 20 is sleeved on the ultrasonic vibrating rod 12. The upper end of the partition sleeve 20 passes through the moving plate 16 and is fixedly connected to the lower end of the partition plate 17. The partition sleeve 20 and the sealing frame 19 cooperate to seal the position of the pressure support spring 23 and the moving plate 16 in the clamping mechanism, so as to avoid contamination of the filtered water and also to prevent the support spring 23 from rusting due to long-term immersion in water, which would affect the service life of the equipment.
[0028] Several water inlet holes 9 are provided on the lower side wall of the filter outer cylinder 1. The several water inlet holes 9 are arranged in a circumferential array and are all located on the outside of the filter plate 8. The arrangement of several water inlet holes 9 can better divert sewage and avoid the problem of severe clogging of the filter plate 8 near the water inlet pipe 3.
[0029] An auxiliary cleaning water pipe 11 is fixedly connected to the side wall of the outer filter cylinder 1. Solenoid valves are installed on the auxiliary cleaning water pipe 11, the inlet pipe 3, and the sewage pipe 4. The end of the auxiliary cleaning water pipe 11 away from the outer filter cylinder 1 is connected to the outlet pipe 10. The outlet pipe 10 is connected to the outer filter cylinder 1 through the auxiliary cleaning water pipe 11. The design of the auxiliary cleaning water pipe 11 makes it easy to rinse the inner wall of the outer filter cylinder 1 and the outside of the filter plate 8 during the cleaning process, further improving the cleaning efficiency.
[0030] Working principle: When in use, open the solenoid valve on the inlet pipe 3. The sewage to be treated enters the bottom inlet cylinder 2 from the inlet pipe 3. Then, it is diverted through several inlet holes 9. The sewage enters the outside of the filter plate 8 and enters the inside of the filter plate 8 after being filtered by the filter plate 8. During sewage filtration, the pressing mechanism ensures that the filter plates 8 can fit tightly together, thereby ensuring the overall filtration effect of the device. The water after being filtered by the filter plate 8 enters the upper sealing cover 5 through the water passage hole 7 and the water guide pipe 6, and is finally discharged from the outlet pipe 10. During backwashing, the solenoid valve on the inlet pipe 3 is closed, and the solenoid valve on the sewage pipe 4 is opened. Clean water is introduced from the outlet pipe 10 and enters the inner side of the filter plate 8 through the guide pipe 6 and the water passage 7. The ultrasonic vibrator 12 is used for cleaning. The adjusting motor 13 drives the internal thread adjusting cylinder 14 to rotate, and then the adjusting screw 15 drives the moving plate 16 to move upward, thereby reducing the force of the pressing mechanism on the filter plate 8. The ultrasonic vibrator 12 can more effectively clean the dirt and impurities between the filter plates 8. At the same time, the solenoid valve on the auxiliary cleaning water pipe 11 is opened, and the cleaning water enters directly from the auxiliary cleaning water pipe 11 to the outside of the filter plate 8. The cleaned sewage is then introduced into the bottom inlet cylinder 2 from the inlet hole 9 and finally discharged from the sewage pipe 4.
