Description

Technical Field

[0001] This utility model relates to the field of liquid filtration technology, and in particular to an integrated liquid filtration device. Background Technology

[0002] In traditional liquid filtration systems, activated carbon filters and dust filters are typically separate devices that need to be installed in series and connected by piping. This separate design has the following drawbacks:

[0003] It occupies a large area and has a complex layout of equipment and pipelines;

[0004] The investment cost is high, requiring the configuration of two independent filter housings and supporting structures;

[0005] The operation and maintenance are cumbersome, requiring separate disassembly and replacement of the filter element.

[0006] Therefore, there is an urgent need for an integrated filtration device to solve the above problems. Summary of the Invention

[0007] To address the technical problems existing in the prior art, this utility model discloses an integrated liquid filtration device. This device integrates an activated carbon filter cartridge and a dust filter cartridge into the same cylinder. The liquid is purified after being successively adsorbed by activated carbon and intercepted by dust. This device has the advantages of compact structure, low cost and convenient operation, and is suitable for precision liquid filtration in chemical, pharmaceutical and other fields.

[0008] To solve the problems of the existing technology, the present invention adopts the following technical solution:

[0009] An integrated liquid filtration device comprises a cylindrical body; the end of the cylindrical body is connected to a cover via a flange; a first support plate and a second support plate are disposed inside the cylindrical body; a first filtration mechanism and a second filtration mechanism are disposed between the first support plate and the second support plate; the first filtration mechanism is located at the center of the cylindrical body; at least two sets of second filtration mechanisms are equidistantly arranged axially on the outer wall of the first filtration mechanism; a flow guide groove is provided inside the second filtration mechanism; the first filtration mechanism is connected to a liquid inlet; and the second filtration mechanism is connected to a liquid outlet; wherein:

[0010] The liquid enters the inner side of the first filtration mechanism through the liquid inlet on the side wall of the cylinder. After filtration, it flows out from the outside of the first filtration mechanism and enters the second filtration mechanism. After secondary filtration, the liquid is discharged from the liquid outlet along the liquid guide groove.

[0011] Furthermore, the first filtration mechanism is a hollow cylindrical shape, with activated carbon filling the space between the inner and outer walls.

[0012] Furthermore, the second filtration mechanism adopts a cylindrical filter element; the cylindrical filter element has an axially penetrating guide groove inside; and a filter screen made of polyester fiber, glass fiber or metal wire mesh is provided between the inner and outer layers of the cylindrical filter element.

[0013] Furthermore, the second filtration mechanism is connected to the first support plate and the second support plate by bolts or slots.

[0014] Furthermore, the second filter mechanism is configured with 6 to 24 filters, and the filtration accuracy is 1 to 10 micrometers.

[0015] Furthermore, a lifting ring is provided on the cover.

[0016] Furthermore, a drain port is provided at the bottom of the cylinder.

[0017] Beneficial effects

[0018] 1. This utility model achieves integrated dual-stage filtration within the same cylinder through a first filtration mechanism and a second filtration mechanism, reducing the equipment footprint by more than 50%; making the filter cylinder structure compact, reducing land use, and freeing up space.

[0019] 2. This utility model solves the problem of redundant and complicated pipeline design in traditional split-type filters, saving 30%-40% of production costs.
