Abstract
A separation device includes a rotating sieve including a mesh, a wall portion that defines a space in which the sieve rotates, a cover member that covers a gap between an annular portion on an outer periphery of the sieve and the wall portion, and an upper frame outside the space in which the sieve rotates, the cover member has an outer portion along the upper frame, an inner portion along the annular portion, and a bent portion between the outer portion and the inner portion, and the bent portion causes the inner portion to follow a change in a relative position between the sieve and the upper frame.
Claims8
A separation device comprising:
- a rotating sieve including a mesh;
- a wall portion that defines a space in which the sieve rotates;
- a cover member that covers a gap between an annular portion on an outer periphery of the sieve and the wall portion;
- and
- an upper frame outside the space in which the sieve rotates, wherein
- the cover member has an outer portion along the upper frame, an inner portion along the annular portion, and a bent portion between the outer portion and the inner portion, and
- the bent portion causes the inner portion to follow a change in a relative position between the sieve and the upper frame.
A method for producing a filtration product using a separation device including
- a rotating sieve having a mesh,
- a wall portion that defines a space in which the sieve rotates,
- a cover member that covers a gap between an annular portion on an outer periphery of the sieve and the wall portion, and
- an upper frame outside the space in which the sieve rotates, in which
- the cover member has an outer portion along the upper frame, an inner portion along the annular portion, and a bent portion between the outer portion and the inner portion, the method comprising:
- supplying a raw material in which a filtration product and foreign matter are mixed to a front surface side of the sieve;
- using the bent portion to cause the inner portion to follow a change in a relative position between the sieve and the upper frame caused by rotation;
- after the rotation, collecting the foreign matter from one of the front surface side and a back surface side of the sieve;
- and
- after the rotation, collecting the filtration product from another one of the front surface side and the back surface side of the sieve.
