Abstract
Claims
1. A colloid filter comprising a combined cartridge (1) and discharge conduit (2), characterized in that: A discharge pipe (2) is installed at the bottom center of the combined sleeve (1), and a sealing cover plate (3) is installed at the top center of the combined sleeve (1). A barrier separation plate (4) is installed inside the combined sleeve (1), and a frustum block (5) is installed on the top surface of the barrier separation plate (4). Through holes (6) are opened on the barrier separation plate (4) and the frustum block (5). A support sleeve (7) is installed at the top center of the frustum block (5), and a discharge groove (8) is opened on the support sleeve (7). A combined connector (9) is installed at the top center of the support sleeve (7), and a limiting connecting sleeve (10) is sleeved on the outside of the combined connector (9). A colloidal filter element (11) is sleeved on the outside of the support sleeve (7), and the colloidal filter element (11) is located below the limiting connecting sleeve (10). The limiting connecting sleeve (10) is located inside the combined sleeve (1).
2. A colloidal filter according to claim 1, characterised in that: The combined sleeve (1) and the discharge pipe (2) are integrated into one structure, and the combined sleeve (1) and the sealing cover plate (3) are connected by a snap-fit seal.
