Description

Apparatus for removing adhesive- coal in coal bin

The present invention relates to an apparatus for removing coal briquettes in a coal storage tank. In particular, the coal storage tank in which coal is attached to a wall inside a coal storage tank for temporarily storing coal for coke production can be identified and removed from an upper portion of the coal storage tank. It is related with a sticking coal removal apparatus.

In general, as shown in Figure 1, the coal storage tank (1) is a large hopper for temporarily storing the coal for the coke for charging in the coke oven, the charging belt (2) is installed on the upper, discharge belt ( 5) In the process of discharging the coal repeatedly, the coal briquettes 3 formed by the intrinsic moisture of the coal are formed on the inner wall of the storage tank 1, and when the coal briquettes are severely formed, the operator after emptying the storage tank 1 completely Since it is necessary to enter the inside of the reservoir (1) directly and remove the coal (3), with the risk of safety accidents, the working efficiency decreases, and usually the operation is continued without removing the coal.

As a result, the volume of the storage tank 1 decreases as much as the coal briquettes 3 are formed, so that the utilization rate also decreases, which adversely affects stable operation. Particularly, in the rainy season, the formation of the coal briquettes 3 occurs due to the increase in intrinsic moisture of coal. Is increased.

If the formation of the coal briquettes 3 continues as described above, the organic work support before and after the storage tank 1 is not smoothly carried out, and thus, unstable operation of one part due to the characteristics of the steel manufacturing industry is achieved in a consistent process. As a result, the operation rate decreases and the quality decreases due to unstable operation.

In the case of an iron hopper, a conventional coal removal device in the conventional reservoir is fixedly provided with a plurality of blasters 4 having a predetermined size outside, or a plurality of magnetic hammers (not shown) on the outer wall of the hopper. Although it is possible to install and operate periodically, this method can not be expected to remove coal from the concrete bin or thousands of tons of large capacity hopper, so the work is continued with the coal. In order to remove the coal, a regular repair work or a scheduled repair schedule is established and the worker is put inside the hopper to remove the coal by using a hand tool.

In addition, there is a method to maintain the inventory of coal in the reservoir through the bypass operation of the reservoir, but in this method, the management value in the management of the computerized inventory of the reservoir can be managed as normal inventory, As copper inventory is generated, the availability of coal in the storage tank is reduced by the amount of coal, and thus the availability rate is lowered. In case of trouble in the charging line due to the lack of coal stock, it is possible to cause an operation interruption. .

The present invention has been made to solve the above problems of the prior art, by removing the coal coal formed in the inner wall of the storage tank by the intrinsic moisture in the coal storage tank can improve the operation and equipment operation rate, improve the coke quality It is an object of the present invention to provide a coal removal device inside a coal storage tank.

After moving to the site where the coal briquettes 3 are formed in the reservoir 1 by the operation of the switch 31, the coal briquette crushing operation is performed. In FIG. 3 and FIG. 6, reference numeral 16 denotes a cable, 27d, 27d 'is a shaft support ring.

Hereinafter will be described the action of the coal removal device in the coal storage tank according to the present embodiment configured as described above.

In the process of discharging coal through the discharge belt 5 under the above-described storage tank 1, when the coal briquettes 3 are severely formed on the inner wall of the storage tank 1, the coal briquettes 3 are removed. After confirming the formed position, the power generated by the operation of the drive motor 10a is transmitted to the traveling roller 11n through the chain 11 so that the base 12 moves on the moving rail 10. When the hoist 13 reaches the upper part of the coal briquettes 3, the driving motor 13a is operated to rotate both drums 15a and 16a, and thus the rope 15 and the cable 16 are guide rollers ( The removal body 20 is moved up and down inside the reservoir 1 by moving on the outer surfaces of 14a and 14b.

At this time, the weight adjustment weight accommodated in the removal body 20 is the rotational power according to the cylinder (22, 23) and the horizontal and vertical screws (24, 25, 26), the driving motor (27j, 27k) is operated at the same time The removal body 20 is filled to have a weight enough to remove the attachment coal 3 inside the reservoir 1 by pressing the attachment coal 3 as a larger weight. For example, if the rotational power of the drive motor (27j, 27k) is 10kg / ㎝ X 2 places the weight adjustment weight (10kg / ㎝ X 2 places) x 10 times or more by filling the weight of the weight adjustment weight By offsetting the weight of the rotational force, the blades 27h-n maintain the rotational force by the rotation of the second shaft 27g so that the coal briquettes 3 can be removed.

When the hoist 13 reaches the upper portion of the coal briquette 3 by the rope 15 and the cable 16, the vertical cylinder 26 is inserted into the coal briquette 3 to remove the body 20. After fixing, the balance of the removal body 20 is maintained as the horizontal cylinders 24 and 25, and the base 27e rotates to the left and right by lifting the cylinders 22 and 23, wherein the base 27e The second shaft 27g rotates while the bevel gear boxes 27i and 27i 'are engaged with and rotated in accordance with the operation of the drive motor while simultaneously driving the drive motors 27j and 27k mounted to the base 27e. Accordingly, the blade 27h-n hits the coal briquettes 3 and removes them. In this process, the horizontal and vertical cylinders 24, 25 and 26 are inserted into the coal briquettes 3 and removed. This prevents the 20 from being pushed out of the coal briquettes 3.

As described above, while the hoist 13 is moved, the coal briquettes 3 inside the reservoir 1 are repeatedly carried out by crushing and removing the coal briquettes 3 inside the reservoir 1 with the blades 27h-n. ) Can be easily removed.

As described above, according to the coal removal device in the coal storage tank of the present invention, by easily removing the coals formed on the inner wall of the storage tank during the charging and discharging of coal through the coal storage tank, to promote stable operation and safety accidents Reduce the occurrence of, and the effect of improving the coke quality and plant operation rate.
