Description

Crushing ORE AUTOMATIC DISPERSION APPARATUS}

The present invention relates to a crushed light dispersing device that distributes iron ore evenly to the screen device during the crushing and sorting process of iron ore to iron iron ore to a size suitable for use in the blast furnace, in particular the crushed light to the outside by the rotation of the rotating plate The present invention relates to a crushed light automatic dispersing device in which the ore is evenly distributed throughout the screen louver network.

In general, in the crushing and sorting process, iron ore (30mm ~ 250mm) with a large particle size is suitable for use in blast furnace (blast furnace). : 8mm or less, 8mm ~ 30mm) is screened and charged into the blast furnace.

In the conventional iron ore crushing, screening device as shown in Figure 1, the screen body 10 is operated by the vibration caused by the eccentricity of the screen main body 20, the iron ore supplied from the upper chute ( 7) Ore flows down the center of this screen louver (5) and small ore (8 mm or less, 8 mm to 30 mm) ore drops to the bottom and is supplied to the blast furnace, and large ore (30 mm to 250 mm) ore flows to the end of the screen net. It is supplied to the lower belt conveyor. In the conventional iron ore crushing and sorting device, the ore is concentrated at the center of the screen louver network 5 so that the screen louver network 5 is intensively worn only at the center, and the left and right sides are not worn at all. Since only the central portion is worn out early, holes are generated in the screen louver network 5, so there is a problem that the screen louver network 5 needs to be replaced early because the sorting operation of the ore is not performed.

The present invention was devised to solve the problems caused by the conventional iron ore crushing, sorting device, iron ore supplied from the upper chute by rotating the blade to the outside by receiving power to the V-belt using a screen drive motor Light is distributed evenly over the screen louver so that the ore is screened throughout the screen louver to extend the life of the screen louver, thus preventing the premature wear of the central part of the screen louver and reducing the life of the screen louver. The purpose is to provide a dispersing device.

The present invention crushed light automatic dispersion device for achieving the above object is a V-pulley connected to the screen driving motor (20) by the V-belt (23) through the shaft shaft 25 and V-pulley (22)

In the device for sorting the crushed light by the vibration of the screen body 10 by the rotation of the shaft shaft 25-1 having a 22-1, the bevel gear 27 at one end of the shaft shaft 25-1 And (27-1), a spur gear (31) is installed at one end of the shaft shaft (25-2) of the bevel gear (27-1), and the spur gear (31) is engaged with the spur gear (31). -1) and (31-3), the spur gear (31-2) is provided so as to mesh with the spur gear (31-1), and the spur gear (31-2), (31-3) Rotating discs 33 and 33 having rotary blades 34 and 34-1 on their respective shaft axes 25-3 and 25-4, respectively.

-1) characterized in that the configuration by installing.

Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

3 is a perspective view of the present invention crushed light automatic dispersing device, Figure 2 is a perspective view of the crushed light sorting device installed with the crushed light automatic dispersing device of the present invention, the crushed light is carried on the upper belt conveyor (2) When the fall down on the lower screen louver network 5, the shaft shaft 25 is rotated by the screen drive motor 20, the screen body 10 is vibrated by the eccentric vibration. At the same time, the bevel gears 27 and 27-1 rotate so that the spur gears 31, 31-1, 31-2, and 31-3 rotate in the direction of the arrow of FIG. 3. Accordingly, since the rotary disks 33 and 33-1 rotate together with the rotary blades 34 and 34-1, the crushed light 7 is screened by the rotary blades 34 and 34-1. Evenly distributed in the louver (5).

At this time, the rotary blades (34) and (34-1) installed on the rotary disks (33) and (33-1) have the crushed light (7) falling on the rotary shafts of the rotary disks (33) and (33-1). It is guided to fall to the / 5 point, and the rotary disks (33), (33-1) acts to push the crushed light (7) outwards so as not to be directed to the center of rotation by the dropped crushed light (7) .

Therefore, the crushed light 7 is evenly distributed on the screen louver network 5.

The present invention, which operates as described above, disperses the crushed light falling to the center part by inducing the crushed light to the outside as the rotating disc rotates, so that the ore is evenly distributed throughout the screen louver network. Preventing intensive wear has the advantage of extending the life of the screen louver.
