The inner belt part 30 may be wound in the annular groove 130 of the one roller 110 and the other roller 120.

Meanwhile, in the first embodiment, as shown in FIG. 4, a separation space s ₁ may be formed between the outer belt portion 20 and the inner belt portion 30.

In the lower direction of the lower surface of the outer belt portion 20 may be provided with a wall 300 that can be bolted perpendicular to the ground (3) (see Fig. 15).

The wall 300 has one side wall (301) provided in the lower direction of the center of the lower surface of the outer belt portion 20; The other side wall body 302 which is provided in the lower side of the lower side of the outer side belt portion 20, may be configured (see Fig. 15).

More specifically, the one side roller 110 or the other side roller 120 in the forward direction by the drive motor in a state in which impurities (5 in Fig. 15) including industrial waste, etc. are seated on the upper surface of the outer belt portion 20. The outer belt portion 20 and the inner belt portion 30 also rotates in the forward direction when rotating so that the impurity 5 is transferred from one side of the outer belt portion 20 to the other side (see FIG. 15). )

At this time, the non-magnetic impurities (51 in Figure 15) of the impurities (5) transferred in the other direction of the outer belt portion 20 of the wall 300 provided in the lower direction of the lower surface of the outer belt portion 20 The other side wall 302 falls in the other direction.

Magnetic impurities (52 in FIG. 15) among the impurities 5 transported in the other direction of the outer belt part 20 receive the magnetic force from the other roller 120 to display the magnetic properties of the inner belt part 30. Under the influence of the outer belt portion 20 in the state attached to the lower surface of the roller 110 is transferred in the direction.

The magnetic size of the inner belt part 30 is changed according to the distance difference from the other roller 120.

That is, since the lower other side of the inner belt portion 30 is closer to the other roller 120, the magnetic size of the inner belt portion 30 gradually increases from the one side roller 110 to the other side roller 120. Become bigger,

Since the lower one side of the inner belt portion 30 is far from the other roller 120, the magnetic size of the inner belt portion 30 gradually decreases from the other roller 120 toward the one roller 110. You lose.

As described above, since the magnetic strength of the inner belt part 30 gradually decreases from the other roller 120 toward the one roller 110, the magnetic impurity attached to the lower surface of the outer belt part 20. 52 is dropped between the one side wall 301 and the other side wall 302 and in one direction of the one side wall 301, respectively,

The weight of the magnetic impurity 52 dropped between the one side wall 301 and the other side wall 302 is relatively heavier than the weight of the magnetic impurity 52 dropped in one direction of the one side wall 301. .

In particular, the inner belt part is gradually moved toward the one side roller 110 from the other roller 120 due to the separation space s ₁ formed between the outer belt part 20 and the inner belt part 30. The strength of the magnetic force on the magnetic impurity 52 by the 30 becomes gradually smaller, and thus the magnetic impurity 52 attached to one side of the lower surface of the outer belt part 20 is one side. It is possible to fall more easily between the wall 301 and the other side wall 302 and in one direction of the one side wall 301.

The upper surface of the inner belt portion 30 is gradually inclined downward toward the one side roller 110 in the other roller 120,

The lower surface of the inner belt portion 30 is gradually inclined upward from the other roller 120 toward the one roller 110.

Thus the vertical distance (d) is the side roller 110 in the other side roller 120, the direction of the spacing area (s ₁₎ is formed between the lateral belt portion 20 and the inner belt portion 30 It gets bigger and bigger.

The vertical gap d of the separation space s ₁ formed between the outer belt part 20 and the inner belt part 30 gradually increases from the other roller 120 toward the one roller 110. As it becomes larger, the magnetic strength of the inner belt portion 30 on the magnetic impurity 52 gradually decreases from the other side roller 120 toward the one side roller 110 in a larger width. Due to this, the magnetic impurities 52 attached to one side of the lower surface of the outer belt part 20 are more easily between the one side wall 301 and the other side wall 302 and in one direction of the one side wall 301. There is an advantage that can be dropped quickly.
