Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a multi-purpose liquid filter. Background Art

[0002] Duplex filters are widely used in lubricating hydraulic equipment. Because they use one active filter cartridge and a second backup cartridge, if the active filter cartridge becomes clogged, the backup cartridge can be immediately switched to the backup cartridge, ensuring that the filter cartridge can be cleaned without stopping the machine. Currently, duplex filters are widely used, but their structures are complex, allowing for single or simultaneous use of one or both cartridges. For example, patent authorization number CN201684464U allows for non-stop maintenance, but the duplex filter cannot filter the liquid twice (i.e., two filter cartridges are connected in parallel), resulting in a limited range of applications and impracticality for universal use. Utility Model Content

A valve 4 11 is provided on the conduit connected to the third three-way joint 10 and the four-way joint 3. The outlet of the third three-way joint 10 is connected to a liquid outlet pipe 12. Ear plates 14 are evenly provided on the outside of the barrel filter 2. The ear plates 14 are triangular block structures and are provided with mounting through holes. The lower ends of the two barrel filters 2 are provided with sewage outlets, and the lower ends of the two sewage outlets are provided with sewage valves 1 7. The outlets of the drain valve 17 are respectively connected to the drain pipe 15.

The upper end of the barrel filter 2 is provided with an exhaust port, and the upper end of the exhaust port is provided with an exhaust valve 16. By opening the exhaust valve 16, the gas inside the barrel filter 2 can be discharged, and the liquid flows into the four-way joint 3 through the liquid inlet pipe 5. Then, open valve 14, and the liquid enters the inside of the two barrel filters 2. The liquid is filtered by the barrel filter 2, and the filtered body fluid is discharged through the liquid outlet pipe 12. In this way, the two barrel filters 2 are filtered in parallel. When filtering in series, the barrel filter on the left is connected. 2 is closed, and valve five 13 is opened. The liquid inside the four-way joint 3 enters the inside of the barrel filter 2 on the right, and the liquid filtered by the barrel filter 2 on the right enters the inside of the barrel filter 2 on the left, and the liquid passing through the barrel filter 2 on the left is discharged through the liquid outlet pipe 12, so that the two barrel filters 2 are filtered in series, thereby filtering the liquid twice, or using one of the barrel filters 2 to work, thereby achieving rapid filtration of the liquid or filtering the liquid twice. The multi-purpose liquid filter has a simple structure and is easy to assemble. It can realize parallel or series connection of two filter barrels, and can also use one of the filter barrels alone for filtration. It is more flexible to use and can meet the filtering needs of different liquids.

[0016] In use: First, when using high-power filtration (i.e., two barrel filters 2 in parallel), first close valve five 13 and valve four 11, open the other valves, and let the liquid flow into the four-way joint 3 through the liquid inlet pipe 5. Then open valve one 4, and the liquid enters the two barrel filters 2, and is filtered by the barrel filters 2. The filtered body fluid is discharged through the liquid outlet pipe 12, thereby making the two barrel filters 2 filter in parallel;

[0017] The second pair of liquids is filtered twice (i.e., two barrel filters 2 are connected in series). The valves 1 4, 2 8, and 4 11 on the left barrel filter 2 are closed, and the other valves are opened. The liquid in the inside of the four-way joint 3 enters the inside of the barrel filter 2 on the right, and the liquid filtered by the barrel filter 2 on the right enters the inside of the barrel filter 2 on the left, while the liquid passing through the barrel filter 2 on the left is discharged through the liquid outlet pipe 12. In this way, the two barrel filters 2 are connected in series to filter the liquid twice.

[0018] When the third pair uses the right barrel filter 2 for filtration, valves 1 4, 3 9, 5 13, and 4 11 on the left barrel filter 2 are closed, and the other valves are opened. The liquid is filtered through the right barrel filter 2 and discharged directly from the liquid outlet pipe 12. When the left barrel filter 2 is used for filtration, valves 1 4 and 3 9 on the left barrel filter 2 are opened, and the other valves are closed. The liquid is filtered through the left barrel filter 2 and discharged directly from the liquid outlet pipe 12.

[0019] Fourth, when there is no need to filter the liquid, open valve four 11 and close the other valves. The liquid enters from the liquid inlet pipe 5 and flows through the four-way joint 3, valve four 11 and the third three-way joint 10, and is finally discharged through the liquid outlet pipe 12.
