Magnetic water purifier

The utility model belongs to the field of sewage treatment equipment, and discloses a magnetic water purifier. The magnetic water purifier includes an outer cylinder, a flow stabilizing cylinder, a magnetic cylinder, a support frame, a driving device, a magnetic system and a clean water tank, wherein the magnetic system includes a plurality of magnetic poles made of permanent magnet materials, and the magnetic poles are arranged in a single-line spiral manner; the flow stabilizing cylinder is arranged in the outer cylinder and fixedly connected with the outer cylinder; the magnetic cylinder is arranged in the flow stabilizing cylinder and fixedly connected with the outer cylinder; the support frame is arranged at the top end of the outer cylinder; the driving device is arranged on the support frame, and a power shaft of the driving device extends into the magnetic cylinder; the magnetic system is arranged on the power shaft of the driving device in the magnetic cylinder, and can be driven by the power shaft of the driving device to rotate freely in the magnetic cylinder; the clean water tank is arranged on the outer side of the upper part of the outer cylinder and communicated with the interior of the outer cylinder. The water purifier adopts the single-line spiral magnetic system made of the permanent magnet materials, so that the magnetic system can work with the magnetic cylinder to form an area with high field intensity. Therefore, the settling process of sludge with magnetic flocculation seeds can be accelerated under the action of the magnetic field, which achieves faster and better separation, as well as remarkable settling effects for magnetic seeds with different size fractions.
