Description

Technical Field

[0001] The present invention belongs to the technical field of coking coal processing, and particularly relates to a washing device for coking coal. Background Art

[0002] The washing device for coking coal is an important link in the coal processing process. Through a series of physical and chemical treatment processes, harmful components such as impurities, ash, and sulfur in raw coal are removed, thereby improving the quality of coking coal.

[0003] In the existing washing work of coking coal, there are the following points that need to be improved:

[0004] 1. When washing coking coal, it is necessary to make the mineral particles in the pulp selectively adhere to the bubbles through the way of stirring and aeration, and be brought to the surface of the pulp to form a foam layer, so as to realize the separation of minerals. However, the stirring structure in the washing tank will affect the subsequent work of scraping foam into the tank and efficient foam pushing work, and it is impossible to control the stirring and aeration structure to move out of the washing tank after use;

[0005] 2. Most of the existing structures for stirring and aerating coking coal need to install multiple groups of stirring structures for use. However, for each additional group of stirring structures, a group of driving structures needs to be added, thus increasing the cost required for the stirring structure;

[0006] 3. When the existing foam scraping and feeding device is in use, the foam scraping structure and the lifting structure cannot be effectively linked. When the foam scraping structure scrapes the foam to the position of the discharge tank, at this time, the lifting structure drives the foam scraping plate to descend to a low position, resulting in the pulp being scraped to the discharge tank, affecting the washing quality of coking coal;

[0007] 4. When the existing efficient foam pushing mechanism is in use, it cannot effectively and stably push the foam that cannot be scraped out by the foam scraping plate to near the foam scraping plate. Secondly, the existing lifting structure for controlling the foam pushing plate is relatively complex, and the manufacturing cost is relatively high. Summary of the Invention

[0022] 3. By providing a foam scraping and feeding mechanism, the setting of this mechanism can automatically control the foam scraping plate to scrape the flotation foam. And when the foam scraping plate is farthest from the first installation box, at this time, the foam scraping plate is just lowered to the lowest position by the first lifting component.

[0040] When coking coal needs to be washed, the coking coal is poured into the washing tank body 1 and water and a series of chemical substances are added to form a pulp with the water. Then, the pulp is stirred and aerated by the pulp stirring and aerating mechanism 5 so that some high-quality coal particles adhere to the bubbles and float to the surface of the pulp to be scraped out to form a foam product. Then, the motor one 45 is turned on. The motor one 45 drives the screw one 42 to rotate through the output end.

[0064] Working principle and usage process of the present invention: When the present invention is in use, when it is necessary to wash coking coal, the coking coal is poured into the interior of the washing box body 1 and water and a series of chemical substances are added, so that the coking coal and water form a pulp. Immediately, the pulp stirring and aerating mechanism 5 stirs and aerates the pulp, so that some high-quality coal particles adhere to the bubbles and float to the surface of the pulp to be scraped out to form a foam product. Immediately, the first motor 45 is turned on. The first motor 45 drives the first screw 42 to rotate through the output end. When the first screw 42 rotates, it drives the first transmission gear 482 to rotate. The rotation of the first transmission gear 482 drives the flexible toothed belt 481 to rotate. The rotation of the flexible toothed belt 481 drives the second transmission gear 483 to rotate, thereby driving the second screw 46 to rotate synchronously.

The synchronous rise of the first nut block 41 and the second nut block 47 drives the lifting plate 43 to rise. The rise of the lifting plate 43 can drive the pulp stirring and aerating mechanism 5 to rise from the interior of the pulp to facilitate subsequent treatment of the foam. When stirring the pulp, the second motor 54 is turned on. The second motor 54 drives the drive shaft 55 to rotate through the output end.

The rotation of the second stirring and aerating assembly 59 drives the third connecting gear 510 to rotate. The rotation of the third connecting gear 510 drives the third stirring and aerating assembly 511 to rotate, so as to be able to stir the pulp. When the first connecting gear 56 rotates, it drives the linkage gear 573 to rotate. The rotation of the linkage gear 573 drives the hollow tube 571 to rotate. The rotation of the hollow tube 571 cooperates with the rotation of the limit bearing 572. The rotation of the hollow tube 571 drives the hollow disc 574 to rotate at the same time. The rotation of the hollow disc 574 drives the stirring plate 575 to rotate, thereby driving the pulp to be stirred. Immediately, the air inlet pipe is inserted into the interior of the hollow tube 571, so that the air can pass through the hollow tube 571 and be discharged through the air outlet holes 576, thereby injecting gas into the pulp.When scraping the foam of the washed pulp, turn on the motor three 334. The motor three 334 drives the rotating disk one 335 to rotate through the output end. The rotation of the rotating disk one 335 drives the sector gear block one 336 to rotate.

When the sliding plate one 3310 slides, it drives the moving plate one 3312 to slide. When the moving plate one 3312 slides, it drives the connecting rod one 3313 to slide. When the connecting rod one 3313 slides, it drives the scraping plate 331 to slide. When the cam one 338 resets, at this time the spring one 3314 resets, so as to drive the scraping plate 331 to automatically reset, in order to scrape the foam on the surface of the pulp. In order to improve the scraping effect on the foam, when the scraping plate 331 scrapes the foam, turn on the motor four 329. The motor four 329 drives the rotating disk two 328 to rotate through the output end. The rotation of the rotating disk two 328 drives the sector gear block two 327 to rotate. The rotation of the sector gear block two 327 drives the rotating gear two 326 to rotate. The rotation of the rotating gear two 326 drives the rotating rod two 325 to rotate.

When the cam two 324 resets, at this time the spring two 3213 rebounds, so as to drive the mounting box one 333 to reset. By setting the sizes of the rotating disk one 335, the sector gear block one 336, the rotating gear one 339, the rotating disk two 328, the sector gear block two 327 and the rotating gear two 326 to be the same, it can make the scraping plate 331 at the farthest distance from the mounting box one 333. At this time, the scraping plate 331 is exactly at the lowest position. When the scraping plate 331 is at the closest distance from the mounting box one 333, at this time the scraping plate 331 is normally at the highest position. At the same time, the long axis of the cam two 324 is a little shorter than the long axis of the cam one 338, which can make the descending length of the scraping plate 331 relatively shorter. The combination of the two can improve the scraping effect on the foam;Since the foam far away from the position of the foam scraping plate 331 cannot be scraped cleanly, by turning on the fifth motor 67, the fifth motor 67 drives the third rotating disc 68 to rotate through the output end.

When the foam scraping plate 331 slides rightward and extends, the foam pushing plate 615 slides rightward and contracts, cooperating with each other, so as to be able to effectively scrape the foam on the surface of the pulp. When adjusting the height of the foam pushing plate 615 so that it can adapt to the foam on the surface of the pulp, by turning on the sixth motor 694, the sixth motor 694 drives the fourth rotating rod 6910 to rotate through the output end.
