The present invention relates to an apparatus for removing iron scraps and lump crushing in steel raw materials for separating and processing iron scraps and peroxide contained in ores in a transport line for transporting ores used as raw materials of steel mills from a ship unloading place to a factory. Iron and steel raw material to prevent damage to the conveyor belt of the transport line or to block the chute while the iron or lump contained in the ore is caught in the chute installed at the change section of the line in the transport line of the ore. The present invention relates to an iron strip removing and lump crushing device.

In general, raw or fuel ores and coal used in steel mills are transported using a long-distance conveyor consisting of a multi-stage line from a ship unloading place to a yard of a factory. In FIG. 1, a transport line of ores used as raw materials of a steel mill is shown. It is shown.

That is, as shown in FIG. 1, the ore 110, which is unloaded from the vessel and stored in the storage hopper 100, is transported through the conveyor 120 of the first transport line P1 through the discharge pump 102. A second transport line P2 is disposed below the first transport line P1 to allow the separate supply of the transportable material as the trolley 132 so that the conveyor 1 of the first transport line P1 is disposed. The ore 110 falls on the conveyor 130 of the second transport line P2 through the chute 122 installed at the end 120.

Next, when the trolley 132 moves and the ore 110 is discharged to the conveyor 140 of the third transport line P3 having a plurality of lines below the ore dropping point of the conveyor 130, the third transport A plurality of conveyors 140 of the line (P3) each transports the ore 110 to the yard near the factory, where the end of the conveyor (130) of the second transport line (P2) to move integrally as a truck 132 A chute 132 is installed to enable line changes of the shipment.

However, as shown in FIG. 2, the transported ore 110 includes not only pure ore 110, but also iron piece I or lump ore (B) whose size is not normal. Iron pieces and lump ore are not a problem during transport through the conveyor (120, 130), but the problem occurs in the chute (122, 132) part of the line change section All.

That is, as shown in Figure 2a, the iron piece (I) included in the transported ore falls into the chute (122) 132, and pinched without falling down, and eventually the corner portion of the iron piece (I) is There is a problem of breaking the belt (120a, 130a) portion of the conveyor (120, 130).

As shown in FIG. 2B, the lump ore B included in the transported ore blocks the inner passage of the chute 122 and 132 without falling into the lower line from the inside of the chute 122 and 132. As shown in FIG. 1, the problem that the ore 110 falls in an abnormal path, that is, outside of the chute 122 and 132, is not a normal transport path.

As a result, the transport of the transport, that is, ore is considerable, and the environment around the transport line due to the ore as the transport falls to the outside of the conveyor (120) 130 (140) without the normal ore transport to the multi-stage line Pollution is also a problem, and in particular, it is difficult to smoothly operate the transport line due to additional treatment and interruption of the transport line, and there are various problems such as incurring costs.

In the related art, in order to process such iron ore ore in the ore, the worker must check and process the iron ore. Therefore, not only the processing time is delayed, but also the safety accident of the worker working in the transportation line may occur. will be.

On the other hand, while the ore transport line has been described as a conventional example, the coal used as fuel in the steel mill also includes iron pieces and lump coal, which is the raw and fuel of the actual steel mill. The problems arise in the shipment.

The present invention has been devised to improve the various problems as described above, the purpose of which is that the ore or iron pieces contained in the ore used as raw materials of steel mills are removed or crushed in the initial transport line, so that An object of the present invention is to provide a scrap metal removal and lump crushing device in an iron and steel raw material that can effectively remove the conveyor breakage and chute blockage of the transport line due to iron scrap and lump mining.

And, the device 1 of the present invention can be largely divided into the screen conveyor 40, the crusher 60 and the iron strip separating conveyor 80, looking at each of these in more detail as follows.

First, the screen conveyor 40 is shown in detail in FIGS. 3 to 5B, and the screen conveyor 40 is such that the lump B and the iron piece I are moved upwards of the first transport line P1. It is installed to be separated from normal ore 6.

In addition, the screen conveyor 40 may include a driving wheel connected to a motor 42 mounted at a central portion of the first base 14 on which the first conveyor 10 of the first transport line P1 is installed. 44, both ends of the chain portion 46 are fitted so as to orbitally move when the motor is driven, and only the normal ore 20 is installed to fall on the first conveyor 10 through a plurality of screen holes 40a.

Next, the shredder 60 is illustrated in FIGS. 3 to 5b, and the shredder 60 is the first installed at the falling position of the screen conveyor 40 and the dropping point of the first conveyor 10. The lump ore B falling on the chute 12 is provided to be crushed.

In addition, the crusher 60 is installed above the side inlet 12b to be configured to crush only lump ore B, and the crusher 60 has a first base provided with a first conveyor outside the chute 12. A crushing gear 64 is connected to a plurality of motors 62 fixed to 14 and rotatably mounted within the chute 12.

On the other hand, the first chute 12 has an upper opening (12a) is formed so that the lump ore (B) falling through the screen conveyor 40 to the upper side, and the normal ore falling through the first conveyor (10) It is provided with the side inlet 12b in which 20 is input.

Lastly, FIGS. 3 and 5A illustrate the iron piece separating conveyor 80. The iron piece separating conveyor 80 is an iron piece which is transferred through the screen conveyor 40 to the upper side of the screen conveyor 40. I) is installed to be separated and transported to the iron piece storage hopper 82 side installed on one side of the first chute 12.

The iron strip separating conveyor 80 is orbitally conveyed between the pulleys 86 driven as a motor 84 mounted on the uppermost side of the first base 14 on which the first conveyor 10 is installed, and the surface thereof. The belt 88 in which the projection 88a in the width direction is integrally formed, and is installed inside the belt 88 to attach the iron piece I to the belt 88 by magnetic force to the storage hopper 82. It is made of a configuration having an electromagnet block 90 to put.

If described in more detail the operation and effects of the present invention made of the above configuration as follows.

As shown in FIGS. 3 to 5, when a certain amount of ore, which is a raw material of an ironworks stored in a storage hopper 2, is unloaded and unloaded by a discharge bucket or the like from a ship, a certain amount is dispensed as the lower feeder 4, and a screen provided below the It falls to the conveyor 40 primarily.

Therefore, the chain conveyor 46 of both ends of the screen 40 is pinched by the driving wheel 44 which is driven integrally by driving the driving motor 42 installed on the base 14. When the orbit is transported while being fixed, the side of the first chute 12 at its end is transported as the first cover 10 while the normal ore 6 in the ore falls down through the screen net hole 40a. It falls on the 2nd conveyor 20 of the 2nd conveyance line P2 below the 1st chute 12 via the inlet 12b.

At this time, the size of the hole 40a of the screen conveyor 40 should be adjusted so as to pass through only the normal ore 6, and eventually, through the screen conveyor 40, the lump ore having a larger size than the normal ore 6 is provided. Only iron (I) and the like contained in (B) and ore unloading are transported as it is.

At this time, the belt 88 is orbitally conveyed by the pulley 86 driven as a drive motor 84 installed on the base 14, the separation conveyor 80 is installed on the upper side where the screen conveyor 40 is constantly transported. At the same time, the electromagnet block 90 is disposed inside the belt 88.

Therefore, although schematically illustrated in the drawing, when the electromagnet block 90 is turned on, the iron piece I being transferred on the screen conveyor 40 is driven by the magnetic force of the electromagnet block 90. When the iron piece I reaches the storage hopper 82 installed at the end dropping point of the separation conveyor 80, the magnetic force is weakened while the electromagnet block 90 of the central part is farther away. The separation process is performed while falling to the hopper 82.

This completely prevents the belt part from being broken while the iron piece is pinched in the conventional chute 12 and 22, and in this case, it is important that the separation conveyor 80 and the lower screen control The gap between the bayers 40 is at least narrowed so that the iron piece I is firmly attached to the belt 88 of the upper separation conveyor 80 and transported, and at the same time, the separation conveyor 80 has an electromagnet 90 The magnetic force of the screen conveyor 40, so that the trajectory is to be started at the central portion of the screen, the electromagnet block 90 should be installed to have a sufficient magnetic force.

On the other hand, when the iron piece conveyed along the belt 88 reaches the falling point of the separation conveyor 80 by the projection 88a integrally formed along the main surface of the belt 88, the iron piece I easily falls. The hopper is stored.

Next, when the lump ore B continuously transported along the screen conveyor 40 is introduced into the chute through an upper inlet 12a formed at an upper portion of the first chute 12, the base installed in the fraud chute 12 is installed. The crushing gears 64 driven by the motor 62 on the 14 crush the lump ore B and the second conveyor 20 of the second transport line P2 together with the normal light 6 introduced through the chute side. ) To fall.

Accordingly, the belt burnout and the chute clogging by the conventional lump ore (B) and the iron piece (I) is completely prevented while the operation rate of the transport line is improved.

Thus, according to the iron strip removal and lump crushing device in the steelmaking material of the present invention, there is an advantage that can effectively remove the conveyor breakage and chute clogging of the transport line by the iron pieces and lumps contained in the ore.

Further, by quickly and simply separating and treating the iron pieces and the lumps contained in the ore without the manual labor of the operator, it is possible to prevent the operation of the transportation line due to the iron pieces or the lumps to maintain the operation rate of the transportation line at all times.

Finally, it is possible to prevent environmental problems caused by falling of transported goods from the transport line to the outside of the transport line, and in particular, to prevent the safety of workers who may be generated during the work on the transport line. It is an excellent effect.

While the subject innovation has been shown and described with respect to specific embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit or scope of the subject innovation as provided by the following claims. I would like to clarify that knowledge is easy to know.
