Description

Technical Field

[0001] This utility model relates to the field of liquid bag filter technology, specifically to a universal liquid bag filter for all core types. Background Technology

[0002] Traditional bag filters often face numerous inconveniences in industrial applications. Firstly, they typically only accommodate a single type of filter element, requiring companies to strictly match specific models when replacing them. In actual production operations, companies often use materials with varying filtration requirements or process fluids with different properties, necessitating the stocking of large quantities of different filter models to meet diverse needs. Furthermore, in special circumstances where existing filter models are incompatible, custom-made filter elements become necessary, further increasing costs. From a management perspective, numerous different filter models and custom-made filter elements require more storage space and introduce greater complexity and difficulty in inventory management, logistics, and equipment maintenance planning. Therefore, we propose a universal liquid bag filter with all filter elements. Utility Model Content

The upward movement of the fixed ring drives all the inclined blocks to move upward, extruding all the extrusion blocks. After extrusion, all the square rods move, which allows the position of all the connecting frames to be adjusted. After adjustment, filter elements of different specifications can be placed on top of all the connecting frames. In this way, the installation of filter elements of different specifications can be completed, thereby effectively improving the applicability. 2.

[0017] The working principle of the universal liquid bag filter provided by this utility model is as follows: During use, first rotate the sealing cover 7 upwards to remove it. After removal, start the motor 34 according to the filter element specifications. The motor 34 starts, causing the threaded rod 35 to rotate. The rotation of the threaded rod 35 drives the fixing ring 31 to move upwards. The upward movement of the fixing ring 31 drives all the inclined blocks 32 to move upwards, squeezing all the compression blocks 23. After squeezing, all the square rods 21 move. The movement of all the square rods 21 adjusts the position of all the connecting frames 22. After adjustment, filter elements of different specifications can be fitted onto all the connecting frames 22. In this way, filter elements of different specifications can be fitted onto the top of all the connecting frames 22. The installation of the filter element effectively improves its applicability. During the process of the inclined block 32 squeezing the extrusion block 23, the T-shaped slider 92 fixed on the inclined block 32 will move along the corresponding T-shaped groove 91. When the extrusion block 23 moves to the appropriate position, the T-shaped slider 92 will limit the extrusion block 23 to prevent it from moving. After the filter element is installed, the air pump 42 can be started to inject compressed air into the interior of the annular air bladder 41. After injection, the annular air bladder 41 inflates and then contacts the sleeved annular air bladder 41. After contact, the annular air bladder 41 can be fixed and the gap between the annular air bladder 41 and the tank 1 can be sealed. After sealing, liquid leakage can be prevented during filtration.
