The present invention relates to a reclaimer basket which can prevent the formation of adherent coal inside the BUCKET of the reclaimer, which is a raw coal discharger, and can separate and discharge moisture from the raw coal. In particular, the present invention relates to a reclaimer basket capable of automatically removing coal briquettes formed inside the basket when discharging the raw coal and separating water contained in the raw coal discharged.

In general, the reclaimer is a device for discharging the raw coal accumulated in the yard and transported to the conveyor belt. As shown in Figure 1 (a), the raw coal 11 accumulated in the yard is loaded on the basket 22 as the bucket wheel 20 of the reclaimer 10 is rotated, the conveyor belt 16 Is sent to the next process.

At this time, since the raw coal 11 is loaded in the yard while being exposed to the atmosphere, it contains a large amount of moisture during the rainy season. As such, when the raw coal 11 containing moisture is loaded onto the basket 22 and discharged to the conveyor belt 16 due to the increase in cohesiveness, the raw coal 11 is entangled inside the basket 22 and adhered to the coal. It forms (12) (refer FIG. 1 (b)). Repeating the discharging operation of the raw coal in this state increases the amount of the coal 12 sticking inside the basket 22 to reduce the loading space inside the basket 22. As a result, the discharging work of the raw coal 11 becomes difficult.

Therefore, in order to solve this problem, when the coal briquettes 12 are formed in the basket 22, the operator directly removes the coal briquettes 12 or uses the high pressure water spraying equipment to remove the coal briquettes 12. Remove However, the removal of the coal briquettes takes a lot of time, and the discharging operation of the raw coal should be stopped during such removal.

On the other hand, when raw coal 11 containing a large amount of water is discharged to the conveyor belt 16, it provides a cause of meandering of the conveyor belt 16. A very difficult problem is caused which reduces work efficiency.

The present invention has been made to solve the conventional problems as described above, by mounting a scraper (SCRAPER) inside the basket of the reclaimer to automatically remove the coal and to install a filter (FILTER) It is an object of the present invention to provide a reclaimer basket capable of discharging moisture contained in the raw coal to the outside of the basket while the basket wheel is rotated until the raw coal is shipped to the basket and discharged to the conveyor belt.

In order to achieve the above object, according to the present invention, is installed on the basket wheel of the reclaimer having a loading space for loading the raw coal so that the raw coal accumulated in the yard can be discharged to the conveyor belt as the bucket wheel is rotated The basket includes a mesh filter net installed at a predetermined position of the loading space, a plate-shaped scraper rotatably installed in the loading space above the filter net, and a drain hole formed at a side wall defining a loading space below the filter net. And a drain pipe installed outside the side wall to communicate with the side wall, wherein the scraper is rotated when the raw coal is loaded in the loading space, thereby preventing the raw coal from tangling on the side wall of the loading space and entering the loading space on the filter network. Moisture contained in the loaded raw coal falls to the loading space under the filter net, and then the side It is characterized in that the drain through the drain through the wall.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

According to the present invention, the loading space for loading raw coal of the basket 50 installed in the basket wheel 40 of the reclaimer 10 is, as shown in FIG. 130 is separated into an upper space A in which the raw coal is loaded and a lower space B in which moisture contained in the raw coal is extracted and collected. The plate-shaped scraper 120 is rotatably installed in the upper space (A).

That is, the scraper 120 is attached to the rotary shaft 110 inserted into the through holes 111A and 111B formed at predetermined positions of the side plates 100A and 100B facing the basket 50. Therefore, the scraper 120 is rotated about the rotation shaft 110 by the external force applied. A drain hole 201 of a predetermined size is formed at a lower end of one side plate (for example, 100A).                     

Referring to FIG. 2, the basket 50 having the structure as described above is installed at predetermined intervals along the outer circumferential surface of the basket wheel 40.

Therefore, as the bucket wheel 40 rotates, the raw coal 11 accumulated in the yard is loaded in the upper space A of the bucket loading space, and the water contained in the raw coal 11 is filtered through the filter net 130. Fall through the lower space (B). Water collected in the lower space B is drained to the outside of the basket 50 through the drain hole 201.

According to a preferred embodiment of the present invention, the drum-shaped bucket 320 is mounted on the outer circumference of the basket wheel shaft 42 exposed to the outside of the basket wheel 40. At this time, the water outlet 320 and the drain hole 201 formed in the lower side plate (100A) of the basket 50 is connected to the fluid communication by the drain pipe (200). Then, a discharge pipe 300 for discharging the collected water to the outside is installed on the side of the bucket 320. Therefore, the separated water collected in the lower space B of each of the baskets 50 installed on the outer circumference of the basket wheel 40 is collected into the water tank 320 through the drain pipe 200 and then externally discharged through the discharge pipe 300. To be discharged.

At this time, as the bucket wheel 40 rotates, the chuck valve 202 is installed in the drain pipe 200 to prevent the separated water collected in the bucket 320 from flowing back into the lower space B of the bucket 50. do. Therefore, when the basket 50 is positioned at the top by the rotation of the basket wheel 40, the separated water collected in the lower space B of the basket 50 is opened by the chuck valve 202 to open the drain pipe 200. Therefore, although the water is collected into the bucket 320, if the bucket 50 is located at the bottom, the reverse flow phenomenon in which the separated water collected in the bucket 320 flows into the lower space B is blocked by closing the chuck valve 202.                     

Hereinafter, the configuration and operation of the reclaimer basket according to the present invention.

The basket 50 according to the present invention is installed along the outer circumference of the basket wheel 40. The bottom of the basket 50 is divided in half and the steel plate (STEEL PLATE; 100C) and the filter net 130 are combined to form the bottom and face each other with the front plate 100D of the basket 50. The side plates 100A and 100B are welded to produce a basket having a predetermined shape. And, the end of the steel plate (100C) of the manufactured basket 50 is welded to combine the water reservoir 140 of a smaller shape than the basket 50 located at the lower end of the filter net 130.

The fixing bolt 101 is fastened to the hole 56 formed in the upper portion of the front plate 100D of the basket 50 to fix the basket 50 to the basket wheel 40.

By inserting the rotating shaft 110 to which the plate-shaped scraper 120 is attached via the bearing 112 through the through holes 111A and 111B formed in both side plates 100A and 100B of the basket 50. The scraper 120 is rotatably installed in the basket 50. Then, in order to prevent the wear of the scraper 120, when the scraper 120 rotates in contact with the inner surface of the basket 50 to remove the attachment coal 12 in the basket 50, 121 ) Is detachably mounted to the scraper 120. That is, elliptical adjustment holes 122 are formed at both edges of the scraper 120, and through holes 123 corresponding thereto are formed in the blade 121. Accordingly, the blade 121 is fixed to the scraper 120 by inserting the fixing bolt 124 into the adjusting hole 122 and the through hole 123.

On the other hand, the water contained in the raw coal 11 loaded on the basket 50 is collected in the water reservoir 140 through the filter network 130. Separation water 150 accumulated in the drip tank 140 is discharged through the drain hole 201 is connected to the drain hole 201 formed in the lower end of the side plate (100A) of the bucket 50 to enable the fluid communication (20) To 320). That is, in order to collect the separation water 150 and discharge it to the outside of the basket wheel 40, the inner drum 210 of the bucket 320 is loosely fitted to the bucket wheel shaft 42 of the basket wheel 40 and Insert the outer drum 220 on the top. The other end of the drain pipe 200 having one end coupled to the drain port 201 is coupled to the external drum 220 fitted in this way.

The bearing 230 is interposed between the inner drum 210 and the outer drum 220 so that the drain pipe 200 and the outer drum 220 may rotate smoothly together with the rotation of the bucket wheel 20. Both sides of the inner drum and the outer drum 210, 220 are sealed by the sealing members 240 and 240A, and the lids 250 and 250A are attached to the outside to assemble the water tank 320. Then, the discharge pipe 300 is installed in the discharge port 301 formed in the cover 250 exposed to the outside.

On the other hand, the solenoid valve 310 is installed in the middle of the discharge pipe (300). The solenoid valve 310 is installed outside the basket wheel 40 and is opened and closed according to a detection signal of the laser sensor 330 of the reclaimer 10 that detects the presence of raw coal. That is, the solenoid valve 310 is opened when there is no raw coal, and the solenoid valve 310 is closed when the raw coal is present.

Thus, as shown in FIG. 5, the raw coal 11 accumulated in the yard while the bucket wheel 40 of the reclaimer 10 is rotated is shipped to the basket 50. The scraper 120 rotates about the rotation shaft 110 by the raw coal 11 to be shipped to remove the coal 12 from the inside of the basket 50. That is, when the scraper 120 is rotated by the raw coal 11 shipped to the basket 50 while the discharge operation of the fuel coal by the reclaimer 10 is continuously performed, the scraper 120 is attached to the edge of the scraper 120. Since the blade 121 scratches the inner surface of the basket 50, the formation of the sticking coal 12 inside the basket 50 is prevented.

In addition, the water contained in the raw coal 11 is extracted and separated through the filter network 130 installed on the bottom surface of the basket 50, and the separated water 150 thus separated is accumulated in the water reservoir 140. At this time, when the position of the basket 50 is at the horizontal top, the chuck valve 202 installed in the drain pipe 200 is opened while the separation water 150 flows to the water tank 320 and the position of the basket 50 is When it is at the horizontal bottom, the chuck valve 202 installed in the drain pipe 200 is closed to prevent the separation water 150 from flowing back from the water tank 320 to the water reservoir 140.

The bucket 320 loosely fitted to the shaft 42 of the bucket wheel 40 is supported by the drain pipe 200 composed of eight (see FIG. 2 (a)), and only the outer drum 220 is supported by the bearing 230. Since it rotates along the basket wheel, the water tank 320 is to collect the separation water (150). The collected water 150 is discharged to the outside by opening the solenoid valve 310 installed in the discharge pipe 300 when there is no raw coal 11 detected by the laser sensor 330 when the reclaimer is turned.

Therefore, according to the present invention, when the coal is formed in the basket, the scraper rotates by the raw coal shipped to the basket without the physical force applied from the outside, so that the blade removes the coal in the basket. By improving the work efficiency and collecting large amount of water contained in the raw coal by the filter network and discharging it to the outside, it is possible to supply the raw coal stably by helping the discharge of high quality raw coal and preventing the equipment accident.

The foregoing is merely illustrative of the preferred embodiments of the present invention and those skilled in the art to which the present invention pertains may make modifications and changes to the present invention without departing from the spirit and gist of the invention as set forth in the appended claims. It should be recognized.
