The present invention relates to a device for charging coal from the hopper hopper of the charging car into the carbonization chamber in the field of steelmaking, and more particularly during the coal loading operation from the hopper to the carbonization chamber using a conventional screw feeder and charging device. The screw feeder is urgently arranged when inoperable relates to an emergency coal induction guide device for guiding the supply of coal from the call hopper to the carbonization chamber.

Fig. 1 shows the charging operation of the coal 62 from the call hopper 61 of the conventional charging vehicle to the carbonization chamber 80, and Fig. 2 shows the coal 62 using the conventional charging apparatus 90. The charging operation is shown, and FIG. 3 shows the processing situation when the conventional screw feeder 63 is inoperable.

1 to 3, in general, the coal stored in the call hopper 61 of the charging vehicle passes through the carbonization chamber 80 through the drop sleeve 81 by rotating the screw 63a by operating the screw hydraulic motor 67. It is charged into the carbonization chamber 80 through an upper charging hole 91.

Prior to the coal charging operation, a cover 2 made of steel blocking the charging hole 91 is usually moved by using a charging device 90 as shown in FIG. Briefly referring to the principle of the charging device 90, when the first cylinder 96 is operated so that the body 98 is moved above the cover 2, and the second cylinder 95 is operated at the position (2) The magnet 93 mounted on the lower side of the 98 is lowered and attached to the upper surface of the cover 92. Since the magnet 93 has a strong magnetic force, the cover 92 is already attached, and at this time, the third cylinder 94 is moved to separate the cover 92 from the charging hole 91.

Thereafter, a drop sleeve 81 which is moved by a cylinder 68 is disposed above the charging hole 91, and an upper side of the drop sleeve 81 forms a spiral tube shape of the screw feeder 63. It is arranged according to the supply port.

Operating the screw feeder 63 while the drop sleeve 81 connects the call hopper 61 and the charging hole 91 to drive the coal 62 through the drop sleeve 81 to the carbonization chamber. 80 feed into.

Meanwhile, the coal hopper 61 includes a plurality of foreign matters 66, such as iron pieces, in addition to the coal 62, and the foreign matters 66 are also carbonized through the screw feeder 63 during the coal supply process. 80) supplied into. However, the foreign substances 66 are often sandwiched between the screw 63a in the screw feeder 63 and the lower opening / closing cover 64 of the screw feeder 63 during charging. When foreign matters 66 accumulate as described above and are sandwiched between the screw 63a and the cover 64, the screw 63a can no longer be rotated and thus the coal charging operation is stopped, and thus, the screw feeder. (63) The cover 64 needs to be opened and closed to remove foreign matters 66 therein.

However, when the lid 64 is opened and closed, the remaining coal 62 in the screw feeder 63 and the coal 62 in the call hopper 61 are poured into the lead furnace, which is an outer furnace bottom of the carbonization chamber 80. In order to process this, the workers are directly administered to open the charging hole 91 to collect and pour the coal into the charging hole 91 using the hand tool 89.

During the manual coal treatment operation as described above, workers are suffocated due to respiratory difficulties due to dust and dust spread around, or burned by a flame 85 ejected from the charging hole 91. Accidents occur frequently.

In addition, during the coal treatment operation as described above, the further coal supply operation is stopped and the operation is delayed, thus causing a problem in the subsequent process, thereby lowering the productivity in the overall process.

In addition, when coal is poured out of the screw feeder 63 as described above, as the peripheral equipment is damaged, the service life of the equipment is shortened, environmental pollution occurs, and problems that adversely affect the coal quality occur.

The present invention has been proposed in order to solve the above-mentioned conventional problems, when the screw feeder is inoperable during the coal loading operation from the call hopper of the charging car to the carbonization chamber, urgently guides the remaining coal from the call hopper to the carbonization chamber safely. It is an object of the present invention to provide an emergency coal guide system.

It penetrates 56a. Accordingly, the connecting rod 51 is free to rotate, and thus the opening and closing plates 57 integrally coupled to the ends of the connecting rod 51 are also freely rotated in the second stage sleeve 30, thereby allowing the second stage sleeve 30 to freely rotate. Opens and closes the passage.

The connecting rod 51 is coupled to the end of the support rod 53a supporting the weight 53 at one side end and the pin 55 and the weight of the weight 53 is appropriately replaced according to the weight of the coal to be adjusted It is possible.

On both sides of the second end sleeve 30, a stopper 52 for preventing the connecting rod 51 from being excessively rotated downward is mounted by a connecting member such as a bolt.

In general, when the weight of the coal 62 flowing from the upper side is heavier than the weight 53, the opening and closing unit 50 is rotated downward to guide the coal 62 downward. And then again to the original position by the weight of the weight 53 serves to seal the passage in the second stage sleeve (30).                     

The first stage sleeve 20 fitted with the upper portion of the second stage sleeve 30 has an inlet pipe 21 connected to the emergency outlet 87 of the screw feeder 63 on the upper side. The emergency outlet 87 is mounted to a lower portion of the cover 54 which seals the lower side of the screw feeder 63, and the lower surface of the emergency outlet 87 is blocked by an unillustrated cover hinged to one side of the circumference. In addition, the inlet pipe 21 is formed in the shape of a fallopian tube to guide the coal 62 discharged from the emergency outlet 87 into the first stage sleeve 20 without external scattering.

On the other hand, the cylinder 5 is mounted on the upper plate 12 of the trolley 10. The cylinder (5) has an operating bar (6) extending upwards, the end of the operating bar (6) is a connecting member such as a support (41) and bolts (83) of the link portion 40 to be described later in detail.

In addition, Figure 9 shows the overall operating state of the emergency coal induction guide device 100 according to the present invention.

7A to 9, the operator operates the cylinder 68 when the screw feeder 63 cannot be operated by the foreign substance 66 or the like to move the drop sleeve 81 from the charging hole 91. Isolate.

Thereafter, the worker moves the moving cart 10 to the charging inlet 91 and operates the lever 8 to supply air to operate the cylinder 5 (see FIG. 7A). When sufficient air is supplied to the cylinder 5, the operation bar 6 of the cylinder 5 is raised and the first end sleeve 20 and the support 41 which are integrally coupled thereto are raised. At this time, the operator opens the lower cover of the emergency discharge port 87 in advance. Since the coal is trapped in the screw feeder 63, the coal does not fall to the bottom until a big impact is applied.

When the support 41 is raised, the guide 42 is raised and the inlet pipe 21 is raised toward the emergency outlet 87 mounted to the lower portion of the screw feeder 63. Meanwhile, the guide 42 lifts one side of the connecting rods 43 pinned at the lower end of the long groove 42a therein, so that the connecting rods 43 are pins on the fixing member 47. Rotated, the support bars 44 pinned to each of the connecting rods 43 are inclined, respectively. While the supporters 44 are inclined, the second end sleeve 30 having the lower end pushed down the support piece 45 pinned thereto is integrally mounted with the support piece 45. Is moved downwards. When the two-stage sleeve 30 is moved downward, the outlet pipe 34 is disposed to correspond to the upper side of the charging inlet (91).

If the cylinder 5 continues to operate in such a state, the inlet pipe 21 of the first stage sleeve 10 which is being raised hits the emergency outlet 87 to correspond to the emergency outlet 87, so that some impact is caused by the screw feeder 63. ) Is delivered inside. Due to such an impact, the foreign matter 66 and the coal 62 that are stuck in the screw feeder 63 are released from the stuck state and pass through the inlet pipe 21 and the first sleeve 20 disposed below. Guided into the second sleeve (30).

When the coal and foreign matters guided into the second sleeve 30 are loaded on the opening and closing plates 57 of the opening and closing portion 50 and are loaded heavier than the weight 53, the opening and closing plates are formed by gravity. 57 is rotated downward to open the passage in the second sleeve 30 so that the coal is dropped and introduced into the carbonization chamber 80 through the charging inlet (91).

The supply into the carbonization chamber 80 continues while the amount of coal flowing from the screw feeder 63 or the call hopper 61 is heavier than the weight 53.

Thereafter, when the weight of the coal is less than the weight 53, the opening and closing plate 57 is raised again by the weight of the weight 53 to open the inner passage of the second sleeve 30 Will be blocked.

When the coal charging process is completed, the operator operates the lever 8 again to lower the cylinder 5 so that the operation bar 6 and the first sleeve 20 and the support 41 connected thereto are operated. Descends.

If the support 41 continues to be lowered, the support 41 is lowered while pressing the connecting rod 43, and thus the pinned connecting rod 43 is rotated. When the connecting rod 43 is rotated, the supporting members 44 pinned thereto are lifted, and the supporting piece 45 pinned thereto is lifted up, and eventually the second sleeve 30 integrally coupled with the supporting piece 45. Is raised so that the outlet pipe 34 is separated from the charging pipe 91.

The worker moves the moving cart 10 to its original position and prepares for the inoperable state of the screw feeder 63 to be generated next.

As described above, even if the inoperable state of the screw feeder 63 is generated by the action of the emergency coal induction guide device according to the present invention, the remaining coal of the screw feeder 63 and the call hopper 61 is smoothly formed in the carbonization chamber. Guidance can be guided to (80).

According to the emergency coal guide system according to the present invention as described above, even if the screw feeder becomes inoperable while supplying coal from the call hopper of the charging car to the carbonization chamber, the remaining coals are smoothly supplied without external scattering into the carbonization chamber. It has a useful effect to prevent the leakage of coal, to clean the working environment and to prevent damage to the surrounding equipment.

In addition, according to the emergency coal induction guide device according to the present invention, since there is no coal scattered, workers do not need to go directly to the field to process the coal scattered as in the prior art, as a result of suffocation or burn disaster of workers. There is a useful effect that is prevented.

Finally, according to the emergency coal induction guide device according to the present invention, since the facilities are not interrupted while coal is scattered around the carbonization chamber as in the prior art, the subsequent process can be maintained and thus the overall process of steelmaking There is a useful effect of improving productivity.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below.
