Description

Conveyor apparatus for transferring raw materials

The present invention relates to a material transfer conveyor device.

In general, raw materials unloaded from a vessel are transported to the yard via a belt conveyor. The raw material transferred to the belt conveyor falls through the chute device to the conveyor device of the next path.

The chute device drops the raw material onto the belt of the conveyor device.

In the process of dropping the raw material from the chute device onto the conveyor device, there was a problem in that the raw material and the equipment were impacted by the high drop, and the falling raw material was scattered out of the conveyor device.

In addition, in general, a skirt installed on a conveyor is a part for preventing falling light from the transported raw materials such as ore or coal from falling off the conveyor belt.

That is, the skirt is disposed on the upper side of the conveyor, and is disposed to substantially contact both sides of the conveyor belt in order to prevent falling light of the raw material deposited on the conveyor belt through the raw material inlet formed in the center of the upper surface.

That is, when the skirt is in direct contact with the conveyor, the skirt or the conveyor is damaged by friction, and when the skirt and the conveyor are far apart, there is a problem in that the raw material leaks into the gap between the skirt and the conveyor.

In this embodiment, the air nozzle 550 injects compressed air toward the H2, and the compressed air may flow in two paths through the Coanda effect to flow along the surface of the air guide 520.

First, the compressed air introduced into the H2 from the air nozzle 550 may flow along the first upper curved surface 521 and the second upper curved surface 522 by the Coanda effect.

When the compressed air is moved from H2 to H1, since the cross section is reduced, the flow rate of the compressed air can be increased, and in this process, the raw material attached to the surface of the first lower belt 112 can be separated more effectively. .

In particular, since the distance to the first lower belt 112 increases toward H1, the raw material adhering to the surface of the first lower belt 112 can be more effectively separated.

And, since the cross-sectional area of the air passing through H1 of the upper end 520c is increased, the pressure is lowered, thereby reducing the speed of the raw material separated from the first lower belt 112, and the raw material is weighed in its own weight. to allow free fall downwards.

When compressed air is directly sprayed from the air nozzle 550 toward the bottom surface of the first lower belt 112, the raw material can be separated quickly and strongly, but the separated raw material can be separated at a high pressure and flow rate of the compressed air. There is a problem of scattering within the housing 300 by the

In addition, since the raw material is freely falling in front of H3, it is possible to scatter the falling raw material of compressed air to excessively scatter the raw material in the housing 300 .

In this embodiment, since the compressed air flowing along the air guide 520 is guided according to the Coanda effect and the pressure is naturally lowered, the raw material attached to the first lower belt 112 is separated while being scattered inside the housing 300 The amount of raw materials can be minimized.

Meanwhile, the remaining compressed air that has not flowed into H2 from the air nozzle 550 is guided to the second housing 320 along the lower curved surface 523 .

That is, since the upper and lower surfaces of the air guide 520 guide the compressed air in the direction in which the raw material falls, it is possible to prevent the scattered raw material and dust from flowing backward through the first opening 301 , respectively. have.

When it is necessary to distinguish each component of the first assembly member 730 and the second assembly member 740, a prefix of "first" or "second" is added to distinguish each component. For example, I will divide it like the first assembly body or the second assembly body.

The cover guard shaft 760 is disposed to pass through the first shaft hole and the second shaft hole of the first assembly body or the second assembly body, and is rotatably disposed with the first shaft hole and the second shaft hole.

The cover guard shaft 760 is arranged to extend along the lower end of each of the extended side covers 422 and 423, and is spaced apart from the second conveyor device 200 by a predetermined distance.

The screw 750 is disposed to extend long in the longitudinal direction from the outer circumferential surface of the cover guard shaft 760 and is spaced apart from the second conveyor device 200 .

Through the rotation of the screw 750, the raw material loaded on the second conveyor device 200 can be moved by pushing it toward the second conveyor device 200, and through this, the raw material is separated out of the second conveyor device 200. can prevent

In particular, since the first screw of the first cover guard 710 is disposed outside the first screw of the first housing guard 610, there is an effect of double confinement of the raw material separated out of the housing guard device 600 .

In addition, since the second screw of the second cover guard 720 is disposed outside the second screw of the second housing guard 620, the effect of double confinement of the raw material separated out of the housing guard device 600 is reduced. have.

In this embodiment, a brush 755 may be further disposed spirally along the outer end of the screw 750 . The brush 755 is in direct contact with the first side part 214 or the second side part 215 , and when the screw 750 is rotated, the first side part 214 or the second side part 215 . ) can be moved inward by sweeping the raw material, thereby minimizing leakage of raw materials to the outside.

In the detailed description of the present invention, although specific embodiments have been described, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments and should be defined by the claims described below as well as the claims and equivalents.
