[0002] In many fields of industrial production and scientific research, the filtration of liquids is of paramount importance. The filtration effect directly affects product quality and the accuracy of experimental results. With the continuous development of science and technology and the increasing demands of production, the performance requirements for filtration devices are also getting higher and higher. Not only are they expected to have high-efficiency filtration capabilities, but they are also required to be easy to clean and maintain in order to reduce operating costs and ensure long-term stable operation.

[0003] Traditional vacuum filtration devices have low filtration efficiency, making it difficult to meet the needs of large-scale production or applications with high filtration speed requirements, thus affecting production progress. Furthermore, cleaning traditional vacuum filtration devices is quite troublesome, as impurities accumulated on the filtration mechanism are difficult to remove completely, often requiring frequent disassembly of various components for cleaning. This is not only cumbersome and time-consuming, but also prone to damage to components during frequent disassembly, increasing equipment maintenance costs. Utility Model Content

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0028] Please see Figure 1-4 This utility model is an easy-to-clean filtration device, including a box 1 and a vacuum component 2. An ultrasonic cleaning tank 3 is fixedly installed inside the box 1. A cover plate 21 is rotatably fitted on the top of the ultrasonic cleaning tank 3. The cover plate 21 should be made of transparent material to facilitate observation of the filtration effect while preventing dust from entering the filtration device and causing contamination. Two sets of symmetrical crossbeams 4 are fixedly connected inside the ultrasonic cleaning tank 3. Several partitions 5 are fixedly installed between the two sets of crossbeams 4. A filter component 6 is set between two adjacent partitions 5.

[0029] The filter assembly 6 includes an open-top bottom filter bottle 7, the bottom of which is open. An upper filter bottle 8 is inserted into the top of the open-top bottom filter bottle 7. A collar 9 is fixedly installed on the outer periphery of the open-top bottom filter bottle 7. Two symmetrical ear plates 10 are fixedly connected to the outer periphery of the collar 9. A compression spring 11 is fixedly connected to the bottom of the ear plates 10, and the compression spring 11 is located between the bottom surface of the ear plates 10 and the bottom surface of the ultrasonic cleaning tank 3. A sealing ring 20 is fitted at the bottom of the open-top bottom filter bottle 7. When the device is performing filtration, the cleaning liquid in the ultrasonic cleaning tank 3 needs to be drained and the cover plate 21 on the top of the ultrasonic cleaning tank 3 needs to be closed. At this time, the cover plate 21 will press down on the upper filter bottle 8, thereby causing the open-top bottom filter bottle 7 to descend. As the filter bottle 7 moves, the collar 9 moves downward, causing the ear plate 10 to compress the spring 11. At the same time, the sealing ring 20 at the bottom of the filter bottle 7 gradually comes into contact with the bottom surface of the ultrasonic cleaning tank 3. At this time, the liquid to be filtered in the filter bottle 7 cannot leak into the ultrasonic cleaning tank 3 through the opening at the bottom of the filter bottle 7. If the filter assembly 6 needs to be cleaned, cleaning liquid needs to be discharged into the ultrasonic cleaning tank 3 and the cover plate 21 at the top of the ultrasonic cleaning tank 3 needs to be opened. At this time, the compression spring 11 rebounds, thereby moving the filter bottle 7 and the upper filter bottle 8 upward. The cleaning liquid in the ultrasonic cleaning tank 3 enters its interior through the opening at the bottom of the filter bottle 7 to achieve cleaning.

[0030] Specifically, an inlet 12 is fixedly connected to the outer side of the open-top filter bottle 7, and a filter screen 13 is fixedly installed inside the open-top filter bottle 7 above the inlet 12. During filtration, impurities mainly accumulate on the filter screen 13 and the inner wall of the open-top filter bottle 7 below the filter screen 13. Therefore, when the cleaning liquid in the ultrasonic cleaning tank 3 enters the interior of the open-top filter bottle 7 through the opening at the bottom, it can effectively clean the filter screen 13 and the inner wall of the open-top filter bottle 7, thereby avoiding frequent disassembly of the filter device for cleaning and improving the working efficiency of the device.

[0031] Furthermore, a conical port 14 is fixedly connected to the top of the open bottom filter bottle 7, and an L-shaped conduit 15 is inserted and fitted to the top of the conical port 14. A conical interface 16 matching the conical port 14 is fixedly connected to the bottom of the upper filter bottle 8. An outlet 17 near its bottom is fixedly connected to the outer periphery of the upper filter bottle 8. An exhaust port 18 located above the outlet 17 is fixedly connected to the outer periphery of the upper filter bottle 8. Gas inside the upper filter bottle 8 is discharged through the exhaust port 18, thereby creating a negative pressure inside the upper filter bottle 8. In this way, the liquid to be filtered is discharged into the open bottom filter bottle 7 through the inlet 12, and after being filtered by the filter screen 13, it can be smoothly discharged into the upper filter bottle 8 through the L-shaped conduit 15. The filtered liquid inside the upper filter bottle 8 can be discharged through the outlet 17.

[0032] The inner wall of the ultrasonic cleaning tank 3 is fixedly connected with several air vents 19 that communicate with the vacuum component 2. An air pipe is fixedly connected between the exhaust port 18 and the air vents 19 (the air pipe is existing technology and is not shown in the figure, so it will not be described in detail here). When the device is working, the vacuum pump in the vacuum component 2 can discharge the gas in the upper filter bottle 8 through the air pipe.

[0033] The operation process of this embodiment is as follows: When the device performs filtration, the cleaning liquid in the ultrasonic cleaning tank 3 is first discharged, and the cover plate 21 on the top of the ultrasonic cleaning tank 3 is closed, causing the filter assembly 6 to move down. The sealing ring 20 at the bottom of the open lower filter bottle 7 gradually comes into contact with the bottom surface of the ultrasonic cleaning tank 3. Then, the liquid to be filtered is discharged into the open lower filter bottle 7 through the liquid inlet 12, and the vacuum pump in the vacuum assembly 2 is started. The vacuum pump draws gas from the upper filter bottle 8 through the conduit, thereby creating a negative pressure in the upper filter bottle 8. The liquid to be filtered is then filtered through the filter screen 13 and discharged into the upper filter bottle 8 through the L-shaped conduit 15. The liquid filtered in the upper filter bottle 8 can be discharged through the liquid outlet 1. 7. Discharge for collection; when cleaning the filter assembly 6, cleaning liquid needs to be discharged into the ultrasonic cleaning tank 3, start the ultrasonic cleaning tank 3, and open the cover plate 21 on the top of the ultrasonic cleaning tank 3. At this time, the compression spring 11 rebounds, thereby driving the open lower filter bottle 7 and the upper filter bottle 8 to move upward. The cleaning liquid in the ultrasonic cleaning tank 3 enters its interior through the opening at the bottom of the open lower filter bottle 7, thereby cleaning the impurities on the filter screen 13 and the inner wall of the open lower filter bottle 7, avoiding frequent disassembly of the filter device, and the outlet 17 and inlet 12 in the adjacent filter assembly 6 can be connected together through the pipe, so that the liquid is filtered multiple times, improving the filtration effect of the device.
