Normal-temperature normal-pressure water body dissolved oxygen high-gradient magnetic separation continuous removal device

The invention discloses a normal-temperature normal-pressure water body dissolved oxygen high-gradient magnetic separation continuous removal device. An upper cover is arranged at the upper end of a casing, an air inlet tube which is communicated with the casing is arranged on one side of the upper portion of the casing, an exhaust tube which is communicated with the casing is arranged on the other side, a water inlet tube which is communicated with the casing is arranged on one side of the lower portion of the casing, a water outlet tube which is communicated with the casing is arranged on the other side, a rotating shaft which is connected with a gear motor through a connecting part is arranged on the casing, an air distribution box which is connected with the air inlet tube is arrangedon the upper portion of the casing, at least a oxygen uptake disk which is filled with magnetic stainless steel wool is arranged on the rotating shaft inside the casing, magnet boxes which is filled with permanent magnets are arranged on the casing of two sides of the oxygen uptake disk below the rotating shaft inside the casing, the polarity of the permanent magnet which is arranged on one side of the oxygen uptake disk differs from the polarity of the opposite end of the permanent magnet which is arranged on the other side, and water is filled in the lower portion of the casing.
