Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0019] See Figures 1 to 2This embodiment discloses a liquid filtration device, including a raw material tank 1. The top cover 2 of the raw material tank 1 has an inlet port 3 and a reflux port 4. The bottom of the raw material tank 1 has an outlet port. The reflux port 4 and the outlet port of the raw material tank 1 are connected by a reflux mechanism. The reflux mechanism includes a circulation pump 9. The inlet of the circulation pump 9 is connected to the outlet port of the raw material tank 1 via a connecting pipe 11, and the outlet of the circulation pump 9 is connected to the reflux port 4 of the raw material tank 1 via a reflux pipe. A filter assembly is provided on the reflux pipe. The filter assembly includes a transparent filter cylinder 7. Filter screens are respectively provided at the upper and lower ends of the internal cavity of the filter cylinder 7. The internal cavity of the filter cylinder 7 is filled with purification particles 15, which are plant particles. The purification particles 15 can be any one of tea leaves, tobacco leaves, or honeysuckle. The particle size of the purification particles 15 is 500 mesh to 1000 mesh.

[0020] The output port of the raw material tank 1 is connected to an output pipe 14, and the end of the output pipe 14 is connected to a three-way connector 12. The inlet of the three-way connector 12 is connected to the end of the output pipe 14, one of the outlets of the three-way connector 12 is connected to the inlet of the connecting pipe 11, and the other outlet of the three-way connector 12 is connected to a drain pipe 13. The connecting pipe 11 and the drain pipe 13 are respectively equipped with opening and closing valves 10.

[0021] The return pipe is divided into a first return pipe 6 and a second return pipe 8 by the filter assembly. The first return pipe 6 has an upper mounting assembly at its bottom, and the second return pipe 8 has a lower mounting assembly at its top. The upper and lower mounting assemblies are symmetrically located on the upper and lower sides of the filter cartridge 7. Each mounting assembly includes a mounting plate 16. The upper and lower mounting plates 16 are locked together by at least two sets of screw and nut assemblies. The filter cartridge 7 is installed between the upper and lower mounting plates 16, so that the upper and lower ends of the filter cartridge 7 are connected to the first return pipe 6 and the second return pipe 8, respectively. The filter screen is placed in the internal channel of the mounting plate 16. Each set of screw and nut assemblies includes a vertically extending screw 17 and two nuts 18. The upper and lower ends of the screw 17 pass through the through holes of the upper and lower mounting plates 16, respectively, and the two nuts 18 are tightened to install the filter cartridge 7 between the two mounting plates 16. The upper and lower ends of the filter cartridge 7 are sealed to the two mounting plates 16 by sealing gaskets.

[0022] A thermometer 5 is installed on the first return pipe 6. The thermometer 5 can measure the temperature of the liquid during the circulation process. The temperature of the liquid can be adjusted by controlling the heating temperature of the raw material tank 1, so that the liquid can be maintained within a preset temperature range during the circulation process after being heated by the raw material tank 1.

[0023] In use, the inlet 3 of this filtration device is connected to a pre-set external inlet pipe. The liquid to be purified enters the raw material tank 1 through the inlet 3. After a preset amount of liquid has entered, feeding is stopped, and the valves 10 on both the connecting pipe 11 and the drain pipe 13 are closed during feeding. After feeding is completed, the valves 10 on the connecting pipe 11 are opened, and the circulation pump 9 starts working. The liquid in the raw material tank 1 enters the filter cartridge 7 through the output pipe 14, the connecting pipe 11, the circulation pump 9, and the second return pipe 8. In the filter cartridge 7, the liquid comes into contact with numerous purification particles 15, which adsorb and filter impurities in the liquid. Under the action of the circulation pump 9, the liquid moves upward and flows back to the raw material tank 1 through the first return pipe 6. This purification process continuously circulates and purifies the liquid inside the raw material tank 1 until a preset purification level is reached. Finally, the valves 10 on the connecting pipe 11 are closed, and the valves 10 on the drain pipe 13 are opened, allowing the purified liquid to be discharged and collected from the drain pipe 13.

[0024] During operation, the power of the circulating pump 9 can be adjusted and controlled according to the type and total quantity of the purified particles 15 in the filter cartridge 7. This allows the liquid pumped by the circulating pump 9 to move the purified particles 15 upwards after entering the filter cartridge 7. The upward flow of the liquid counteracts the gravity of the purified particles 15, suspending them in the filter cartridge 7. This ensures sufficient contact between the liquid and the purified particles as the liquid passes through the filter cartridge 7, thereby improving purification efficiency. Furthermore, the suspended purified particles 15 not only have a strong ability to purify the liquid but are also less prone to clogging during the purification process. The filter screens at the top and bottom of the filter cartridge 7 prevent the purified particles 15 from flowing out.

[0025] In actual use, different models of filter cartridges 7 can be replaced according to usage requirements. The type of purified particles 15 inside the filter cartridge 7 can also be selected and replaced according to actual usage needs. During replacement, simply turning the nut 18 of the screw and nut assembly is sufficient to disassemble and assemble the filter cartridge 7; the operation is convenient and quick.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
