Here, the open position may mean a state in which dust is sucked by the blocking of the duct 200 is released. Preferably, the open position means a state in which the suction interference of the dust by the opening and closing plate 500 is minimized and is disposed perpendicular to the horizontal cross section of the duct 200, as shown in FIG. 5.

That is, the open position refers to the rotation of the weight portion 600 when the tripper car 30 stops after the movement of the tripper car 30 on the upper side of the hopper 20 which requires the distribution of raw materials among the hoppers 20. As the opening and closing plate 500 rotates in conjunction with the mean, the opening and closing plate 500 means a position to open the duct 200. At this time, the weight 600 is rotated by the contact and movement of the contact member of the tripper car (30). Accordingly, when the tripper car 30 drops the raw material through the inlet 21 of the hopper 20 to the inside of the hopper 20, the dust collecting device 2 for supplying the raw material to the dust collecting hole 22. The dust is sucked through the duct 200 disposed.

The shaft 400 is formed in a cylindrical shape and is disposed through the duct 200. In addition, the shaft 400 is disposed in the duct 200 to be rotatable. At this time, the shaft 400 is disposed to rotate in the direction of travel of the tripper car 30.

The shaft 400 may be disposed in the first duct 210 and the second duct 220, respectively. Accordingly, the shaft 400 disposed in the first duct 210 may be called a first shaft. In addition, the shaft 400 disposed in the second duct 220 may be referred to as a second shaft.

The opening and closing plate 500 may be disposed in the duct 200. At this time, the opening and closing plate 500 may rotate in conjunction with the rotation of the shaft (400). Accordingly, the opening and closing plate 500 may open and close the duct 200.

The opening and closing plate 500 may be formed in a shape corresponding to the internal shape of the duct 200. For example, when the cylindrical duct 200 is used, the opening and closing plate 500 may be provided in a disk shape. Here, the opening and closing plate 500 disposed in the first duct 210 may be referred to as a first opening and closing plate. In addition, the opening and closing plate 500 disposed in the second duct 220 may be referred to as a second opening and closing plate.

After the weight 600 is in contact with the contact member of the tripper car 30, the weight portion 600 may rotate based on the center of the shaft 400 by the movement of the tripper car 30. Accordingly, the shaft 400 and the opening and closing plate 500 also open and close the duct 200 in conjunction with the rotation of the weight portion 600. Here, the weight 600 disposed in the first duct 210 may be referred to as a first weight. However, the weight 600 disposed in the second duct 220 may be referred to as a second weight.

The weight portion 600 is disposed eccentrically on one side of the shaft 400. Accordingly, when returning from the open position to the blocking position, the return to the blocking position can be proceeded quickly by the weight of the weight portion 600.

The weight portion 600 may be formed as a fan-shaped or tapered plate, as shown in (a) of FIG. 4. Accordingly, the weight portion 600 may include an inclined surface 610 disposed at a predetermined angle θ based on the imaginary line L vertically passing through the center C of the shaft 400. At this time, the distance from the line L to the inclined surface 610 increases as the distance from the center (C) of the shaft 400.

The inclined surface 610 is in sliding contact with the contact members 38 and 39 after being in contact with the contact members 38 and 39. Accordingly, the opening and closing plate 500 can rotate at a predetermined speed.

Hereinafter, the opening and closing of the duct 200 will be described with reference to FIGS. 4 to 6.

Referring to FIG. 4, when the tripper car 30 moves along the rail 3, the opening / closing plate 500 is positioned at the blocking position by the weight of the weight 600, so that each of the ducts 200 Block the inside. Accordingly, since there is no granulation of raw materials for the hopper 20 during the movement of the tripper car 30, it is possible to block the duct 200 without dust generation to improve the dust collection efficiency.

Referring to FIG. 6A, as the tripper car 30 moves, lower edges of the contact members 38 and 39 of the tripper car 30 preferentially contact the inclined surface 610.

Referring to FIG. 6B, when the contact members 38 and 39 are in contact with the inclined surface 610 and then move along the traveling direction, the upper edges of the contact members 38 and 39 may be inclined ( While pushing 610, the weight portion 600 is rotated in the advancing direction. Accordingly, only the duct 200 corresponding to the hopper 20 requiring granulation of the raw material is opened to improve the dust collecting efficiency of the dust collecting device 2 for supplying raw materials.

For example, the first contact member 38 opens only the second duct 220 disposed in the open position by rotating the weight 600 disposed in the second duct 220. In addition, the second contact member 39 rotates the weight portion 600 disposed in the first duct 210 to open only the first duct 210 corresponding to the hopper 20 that needs to be filled with raw materials.

5 and 6 (c), the moving tripper car 30 stops at a position where raw material distribution is necessary. Accordingly, since the edge of the inclined surface 610 is located on the upper surfaces 38a, 39a of the contact members 38, 39, the opening and closing plate 500 is located in the open position.

In this case, the maximum distance D1 to the inclined surface 610 based on the line L may be the same as the separation distance D2 from the center of the shaft 400 to the contact members 38 and 39.

Accordingly, as shown in FIG. 6C, the opening and closing plate 500 is disposed perpendicular to the upper surfaces 38a and 39a of the contact members 38 and 39. Therefore, since the opening and closing plate 500 is positioned in a state in which the suction interference of the dust by the opening and closing plate 500 is minimized, the dust collection efficiency of the dust collecting device 2 for supplying raw materials can be improved.

When the supply of the raw material by the tripper car 30 is stopped, the tripper car 30 moves. Accordingly, the contact members 38 and 39 are separated from the inclined surface 610, and as shown in Figs. 4 and 6 (a), the weight 600 is in the opposite direction to the traveling direction by its own weight Rotate to block the duct 200.

As shown in FIG. 6B, when the opening and closing plate 500 is disposed to be inclined at a predetermined angle, suction interference, eddy current, and the like are generated by the opening and closing plate 500. Therefore, the position of the opening and closing plate 500 shown in (b) of Figure 6 is less dust collection efficiency than the position of the opening and closing plate 500 shown in Figure 6 (c).

That is, when the raw material is supplied by the tripper car 30, the raw material supply dust collecting device 2 is placed in the state in which the opening and closing plate 500 is disposed perpendicular to the horizontal cross-section of the duct 200 to the raw material The dust collection efficiency of the supply dust collector 2 can be improved.
