Description

Apparatus for recovering fallen coal

The present invention relates to a charcoal recovery device. And more particularly, to a fuel recovery device for recovering raw materials falling from the belt conveyor to the outside and returning the raw materials to the belt of the belt conveyor.

In general, a caterpillar belt conveyor is used to transport iron ore or coal ores such as coal used in steel mills from a ship or yard to a destination located at a remote location.

1 is a view showing a belt conveyor for conveying a raw material such as iron ore or coal.

1, the belt conveyor 2 has a drive pulley 10 and a driven pulley 20, and a carrier belt (not shown) is disposed between the drive pulley 10 and the driven pulley 20, 30 may be disposed.

A plurality of carrier rollers 40 for supporting the carrier belt 30 and a plurality of return rollers 60 for supporting the return belt 50 are spaced apart from each other by a predetermined distance. Here, the carrier belt 30 may be a belt that carries and transports the raw material C, and the return belt 50 may refer to a belt that moves to the drive pulley 10 after unloading the raw material.

That is, the endless belt driven by the driving pulley 10 and the driven pulley 20 can be divided into the carrier belt 30 and the return belt 50 on the basis of the conveyance and unloading of the raw material.

The carrier roller 40 and the return roller 60 may be rotatably disposed on the frame structure 70, as shown in Fig.

2, the raw material C conveyed by the carrier belt 30 is dropped onto the return belt 50 through external impact or vibration to generate a flame F. As shown in FIG.

Then, the flame F is deposited on the return belt 50, and then transported by the return belt 50. Accordingly, the flame F conveyed by the return belt 50 can damage the return roller 60 due to cumulative interference with the return roller 60.

In addition, the return belt 50 may be damaged by the flame F, and fire or the like may be caused by adhesion of the flame F.

As a result, when the facility trouble occurs, an excessive amount of work is required, resulting in a problem of stopping the operation and increasing the workload of the worker.

Furthermore, the flame F deposited on the return belt 50 may fall and accumulate on the floor. These cumulative burrs are directly handled by the inspector using a flushing operation or a shovel.

However, if the cumulative amount is excessive, direct processing becomes difficult, thereby causing fire risk and belt skewing, resulting in various problems.

For example, the flame F is dropped onto the inner side surface 110 on the lower side of the recovery belt 100, and the vibration sensor 600 senses the vibration of the recovery belt 100 located between the lower support rollers 320 .

Then, the vibration sensor 600 can transmit a signal including the vibration amount information to the control unit 700.

The control unit 700 may analyze the signal transmitted from the vibration sensor 600 to determine the difference in vibration amount.

For example, when the flame F is accumulated on the inner side surface 110 on the lower side of the recovery belt 100, a difference occurs in the amount of vibration, and the controller 700 controls the flame 110 The driving unit 400 can be driven.

The control unit 700 drives the driving unit 400 when the predetermined amount of flame F is accumulated on the inner surface 110. However, Of course.

The cleaner 800 may drop the flame F transferred along the return belt 50 of the belt conveyor 2 to the inner surface 110 of the recovery belt 100. [

The control unit 700 can prevent the return belt 50 from being damaged by adjusting the position of the cleaner 800. The control unit 700 controls the position of the cleaner 800 so that the return belt 50 is not damaged.

For example, when the frame 500 of the flame-catching recovery device 1 is moved, the control unit 700 can raise the cleaner 800. Then, after the frame 500 of the flame-catching and recovering apparatus 1 is moved, the control unit 700 can lower the cleaner 800.

At this time, the flame-catching recovery device 1 may further include a position sensor (not shown) for detecting the position of the return belt 50. Accordingly, the controller 700 can adjust the position of the cleaner 800 in consideration of the position (height from the ground) of the return belt 50 sensed by the position sensor.

The lifting device 700 presses the return belt 50 through the cleaner 800 to drop the flame F transferred through the return belt 50 to the recovery belt 100, (F) can be removed.

The guide roller 1000 may be rotatably disposed on the frame 500. The guide roller 1000 can prevent the recovery belt 100 from skewing.
