[0002] Pharmaceutical water is widely used in drug production and biotechnology. The quality of purified water, water for injection, and pure steam directly affects the production quality of drugs. With the rapid development of the modern pharmaceutical industry, increasingly stringent requirements for energy conservation, environmental protection, and safety have emerged, leading to a new era of comprehensive development for pharmaceutical water products that reflect contemporary scientific and technological levels. When the turbidity of the raw water does not meet the influent standards of subsequent treatment equipment, the pretreatment system requires a multi-media filter to remove large particulate impurities, suspended solids, colloids, and other contaminants from the water.

[0003] To improve filtration efficiency, current multi-media filters typically employ two sets of multi-media filtration structures working in tandem. However, the filter media in these filters requires periodic replacement. When one set of media needs replacement, the filter must be shut down, leading to a decrease in filtration efficiency. Therefore, this invention proposes a multi-media filter to address the shortcomings of existing technologies. Utility Model Content

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-4 As shown, this embodiment proposes a multi-media filter, including a filter housing 1. The filter housing 1 has an upper mounting cavity 2 and a lower storage groove 3 inside. The mounting cavity 2 has a first mounting seat 4 and a second mounting seat 5. The first mounting seat 4 and the second mounting seat 5 are respectively provided with a first cylinder 6 and a second cylinder 7. The first cylinder 6 and the second cylinder 7 are respectively detachably provided with a first multi-media filter core 8 and a second multi-media filter core 9. A first inclined chute 10 is provided between the upper ends of the first cylinder 6 and the second cylinder 7. The first inclined chute 10 is provided to facilitate the smooth introduction of the filter into the second multi-media filter core 9 when the cover plate 16 is moved. A second inclined chute 11 is provided on one side of the first cylinder 6. The second inclined chute 11 can guide the water pumped in by the second pump assembly into the first multi-media filter column core 8, and the water intake process of the second pump assembly does not interfere with the disassembly and assembly of the first multi-media filter column core 8. The first pump assembly is provided inside the mounting cavity 2. The first pump assembly is connected to the first mounting base 4 and the first inclined chute 10. A second pump assembly is provided on the outer wall of the filter housing 1 on one side of the temporary storage tank 3. The second pump assembly is connected to the second inclined chute 11. The bottoms of the first mounting base 4 and the second mounting base 5 are both connected to the temporary storage tank 3 through the first discharge pipe 12. A second discharge pipe 13 is provided on the first discharge pipe 12. A first valve 14 is provided on the first discharge pipe 12. A second valve 15 is provided on the second discharge pipe 13.

[0021] In this multi-media filter, water enters the first cylinder 6 and is filtered by the first multi-media filter core 8. Then, it enters the first inclined chute 10 via the first pump assembly, and then enters the second cylinder 7 via the first inclined chute 10 to continue filtration by the second multi-media filter core 9. Finally, it is discharged from the second discharge pipe 13 of the second mounting base (during this process, the second valve 15 is open and the first valve 14 is closed). Since the first multi-media filter core 8 serves as the primary filter, the filter media needs to be replaced first. When replacing the first multi-media filter core 8, the first pump assembly is first shut off. Then, the second multi-media filter core 9 serves as the primary filter. The second valve 15 on the second discharge pipe 13 at the bottom of the second mounting base 5 is closed, and the first valve 14 on the first discharge pipe 12 at the location of the second mounting base 5 is opened, allowing the water filtered by the second multi-media filter core 9 to be discharged into the temporary storage tank 3. After the replacement of the first multi-media filter core 8 is completed, the water is discharged from the second cylinder 7 through the second multi-media filter core 9. The filtration performance of filter column 8 is better than that of the second multi-media filter column 9. Therefore, the second multi-media filter column 9 serves as the first stage of filtration, and the first multi-media filter column 8 serves as the second stage of filtration. The water in the temporary storage tank 3 that has undergone the first stage of filtration can be pumped into the first multi-media filter column 8 for the second stage of filtration by turning on the second pump assembly. Then, the discharged clean water is discharged through the second discharge pipe 13 on the first mounting base 4 (at this time, the first valve 14 on the first discharge pipe 12 at the first mounting base 4 is closed, the clean water does not enter the temporary storage tank 3, and the first pump assembly is turned off during this process). When continuous filtration necessitates the replacement of the second multi-media filter column 9, which serves as the primary filter, the first valve 14 on the first discharge pipe 12 at the first mounting base 4 is opened, and the second valve 15 on the second discharge pipe 13 at the first mounting base 4 is closed, allowing water in the first mounting base 4 to enter the temporary storage tank 3. After the replacement of the second multi-media filter column 9 is completed, the water in the temporary storage tank 3 is pumped back into the first multi-media filter column 8 through the second pump assembly. Then, the first valve 14 and the second valve 15 at the first mounting base 4 are closed, and the first pump assembly is turned on, allowing water to continue to be pumped into the new second multi-media filter column 9 to complete the filtration. The filtered clean water is discharged from the second discharge pipe 13 at the second mounting base 5 (the first valve 14 at the second mounting base 5 is closed, and the second valve 15 is open).

[0022] The filter housing 1 is slidably provided with a cover plate 16 on its top, and the top of the cover plate 16 is provided with a water inlet hose 17 adapted to the position of the first multi-media filter core 8. The slidably provided cover plate 16 allows water to enter from the first multi-media filter core 8 or the second multi-media filter core 9 through the water inlet hose 17. When replacing the first multi-media filter core 8, the cover plate 16 is slid to one side to align the water inlet hose 17 with the second multi-media filter core 9.

[0023] The cover plate 16 is provided with a recessed groove 18, and the recessed groove 18 is provided with a through hole 19. The position of the through hole 19 is adapted to the position of the second multi-media filter core 9. A sealing plate 20 is slidably provided on the recessed groove 18. By providing the through hole 19 and the sealing plate 20, when replacing the second multi-media filter core 9, the sealing plate 20 can be slid open, and then the second multi-media filter core 9 can be replaced through the through hole 19.

[0024] The first pump assembly includes a first water pump 21 and a first connecting pipe 22. The input end of the first water pump 21 is connected to the inside of the first mounting base 4, and the output end of the first water pump 21 is provided with the first connecting pipe 22. The upper end of the first connecting pipe 22 is connected to the inside of the first inclined chute 10. Starting the first water pump 21 will discharge water from the first mounting base 4 into the first inclined chute 10, and then guide the water through the first inclined chute 10 to the second multi-media filter column core 9 for filtration.

[0025] The second pump assembly includes a second water pump 23 and a second connecting pipe 24. The input end of the second water pump 23 is connected to the interior of the temporary storage tank 3, and the output end of the second water pump 23 is provided with the second connecting pipe 24. One end of the second connecting pipe 24 leads to the interior of the upper end of the second inclined chute 11. Starting the second water pump 23 can pump the temporary storage tank 3 into the first multi-media filter column core 8 for filtration.

[0026] The first connecting pipe 22 is equipped with a third valve 25, and the second connecting pipe 24 is equipped with a fourth valve 26. The valves are used to control the opening and closing of different passages.

[0027] This invention features a temporary storage tank 3 located at the bottom of the filter housing 1. The bottoms of the first mounting base 4 and the second mounting base 5 are connected to the temporary storage tank 3 via a first discharge pipe 12. A first pump assembly connects the first mounting base 4 and the first inclined chute 10, and a second pump assembly connects the temporary storage tank 3 and the second inclined chute 11. This allows the multi-media filter to form multiple pathways for filtration. The multi-media filter can continue filtration without stopping when replacing the first multi-media filter core 8 or the second multi-media filter core 9, thus improving its operating efficiency.
