のように目詰まりを生じない。(Effects of the invention) As described above, this invention uses a cylindrical dust separator for ventilation equipment, with an inlet pipe tangentially provided on the peripheral wall and an outlet pipe connected to the blower suction port on the upper wall. Inside the processing case, there is an upper end plate with multiple through holes leading to the outlet pipe in the center and a large number of pins hanging vertically from the outside to the inside in a staggered manner and at different heights on the lower surface of the periphery. It consists of a lower end plate with a boss in the center and a number of pins arranged concentrically in a staggered manner and at different heights on the periphery from the outside to the inside, and the outer side is the peripheral wall and upper wall of the processing case. A non-magnetic processing element with a size close to that of the upper and lower end plates with a zigzag air flow path formed between the pins of the upper and lower end plates is installed, and this processing element is connected to a support frame with a magnet at the lower end through the boss part. Install the magnet so that it rotates in opposition to the coil attached to the boss on the bottom wall of the processing case, or install the coil and commutator directly on the bottom end of the processing case and connect the coil to the wall of the motor case on the bottom of the processing case. Connected to the upper end of the main shaft, which is rotated facing the magnet installed in the
Since a magnetic plate is arranged in a ring shape on the inner surface of the peripheral wall of the processing case, the air in the working chamber flowing into the processing case through the inlet pipe collides with the processing element with force, and moves between the upper and lower pins from the outside to the inside. It passes through the air in a zigzag pattern, causing various types of dust contained in the air to frequently collide with a large number of parallel pins, and the magnetic material is Regardless of whether it is a non-magnetic material, fine dust with a large specific gravity can be efficiently separated from the airflow to the surrounding area, and magnetic particles such as iron powder can be reliably captured by the magnetic plate. In this way, the air flow can be sufficiently purified, preventing wear and tear on the blower and helping to prevent air pollution, and does not cause clogging like conventional filter members. .
