Description

Technical Field

[0001] The utility model relates to the technical field of double-barrel filters, in particular to a novel double-barrel filter. Background Art

[0002] A duplex filter is an industrial filtration device consisting of two independent filter cartridges. One cartridge filters liquids while the other is cleaned or ready for use. This design enables a continuous filtration process, improving efficiency and reducing downtime. Duplex filters are commonly used in industries such as water treatment, chemicals, and pharmaceuticals, effectively removing solid impurities from liquids to meet the needs of various processes.

The outsides of the multiple connecting disks 19 are rotatably connected to movable chucks 20, and filter elements 21 are engaged and connected between the multiple movable chucks 20 and the fixed chuck 14. One side of the end faces of both sides of the two stirring frames 8 is fixedly connected to a guide plate 30;

[0036] When the filter is in use, the stirring frame 8 is driven to rotate by the second servo motor 7, so that the guide plate at the upper end of the stirring frame 8 can guide the liquid entering the filter cartridge 1 to flow toward the middle. At the same time, the transmission rod 10 is driven to rotate by the third servo motor 9, so that the filter element 21 inside the stirring frame 8 can rotate, so that the stirring frame 8 and the filter cartridge 1 can rotate in opposite directions, effectively increasing the contact opportunity between solid particles and the filter medium, strengthening the interaction between the liquid and the filter element 21, and significantly improving the filtering effect.

[0037] The outer sides of the upper ends of the two filter cartridges 1 are provided with grooves 24, and the interiors of the two grooves 24 are provided with rubber blocks 25.

During this process, the staff controls the second servo motor 7 through the external controller to drive the stirring frame 8 to rotate, and uses the guide plate at the upper end of the stirring frame 8 to guide the liquid to flow to the middle of the filter cartridge 1. At the same time, the third servo motor 9 drives the transmission rod 10 to rotate, so that the filter element 21 rotates, thereby enhancing the contact opportunity between solid particles and the filter medium and improving the filtration effect. When the filter cartridge 1 on one side has been used for a long time, the reversing valve 27 introduces the liquid into the filter cartridge 1 on the other side for the same filtration operation. In addition, the staff can adjust the height of the cover 6 by operating the first servo motor 3, and drive the push rod 18 through the fourth servo motor 15 to push the movable chuck 20 to move, so that the filter element 21 is disengaged from between the movable chuck 20 and the fixed chuck 14, so that the filter element 21 can be replaced quickly and conveniently, significantly reducing manual operation time and improving work efficiency.
