Description

Technical Field

[0001] The utility model relates to the technical field of coke oven coal charging, and more specifically, the utility model relates to a coal pressing wheel for compacting the coal surface after coal charging in a coke oven. Background Technique

[0002] After the coal cake is charged in the stamping coke oven, there is always a floating coal layer about 0.1 m thick remaining on the top surface of the coal cake. Its density is much smaller than that of the coal cake. And due to the uneven feeding of each feeder along the length direction of the coal cake, the floating coal layer is uneven, with a height difference of about 0.2 m. During the production process of stamping coking, the floating coal layer on the top surface of the coal cake charged into the furnace will cause the following problems: First, after the coal cake enters the carbonization chamber, this layer of floating coal will float to the top of the carbonization chamber due to the action of hot air. In the long run, it will block the flue gas channel at the top of the carbonization chamber and affect the quality of coke. Second, the floating coal can only turn into coke powder in the carbonization chamber and cannot form coke, resulting in waste of raw materials. Third, when the coal cake charged into the furnace enters the carbonization chamber, due to the strong heat radiation in the carbonization chamber, the floating coal layer burns incompletely and generates a large amount of raw gas, which escapes from the open furnace door and seriously pollutes the environment. In order to overcome the adverse effects brought by the above floating coal layer, the production process of stamping coking requires the floating coal layer to be scraped and compacted. And this work mainly relied on manual scraping and compacting with a spade before. Doing so not only increases the labor intensity and danger of workers, but also easily causes uneven compaction of the floating coal and poor compaction effect, and low work efficiency. Later, a simple device, the coal pressing wheel, was made for compaction, but the degree of compaction and flatness are not enough.

[0003] Therefore, there is an urgent need for a coal pressing wheel for compacting the coal surface after coal charging in a coke oven to solve the above problems. Content of the Utility Model

[0023] The compaction mechanism includes a compaction platform 13, which is arranged on one side of the frame 2. A scraper 14 is welded to the bottom of the compaction platform 13. Two compaction wheel frames 15 are welded to the bottom of the compaction platform 13. A compaction wheel shaft 16 penetrates through the bottom end of the compaction wheel frame 15. Compaction wheels 17 are fixedly installed at both ends of the compaction wheel shaft 16. Four hinge seats 18 are welded to the top of the compaction platform 13. Two hinge frames 19 are arranged on the top of the compaction platform 13. Connecting arms 20 are welded to the tops of the two hinge frames 19. A vibration motor 21 is fixedly installed on the top of the compaction platform 13.

[0024] All four U-shaped limit buckles 4 are fixedly installed on the bottom of the frame 2. The walking shaft 3 is rotatably connected to the frame 2.

[0025] The drive motor is fixedly installed on the frame 2, and the output shaft of the drive motor is in transmission connection with the walking shaft 3.

[0026] The limit wheel 9 is rotatably connected to the wheel shaft 8, and the top of the limit wheel 9 contacts the bottom of the walking mechanism platform 1.

[0029] The specific implementation method is as follows: When using the present utility model, the compaction platform 13 is on the coal surface, and then the drive motor is started. It drives the walking wheels 5 to rotate. The rotation of the walking wheels 5 causes the machine to move on the walking mechanism platform 1. Then the limit wheels 9 move under the walking mechanism platform 1, playing a limiting role to ensure the stability of the movement. This causes the frame 2 to move, thereby driving the support 10 to move. The support 10 pushes the connecting arm 20 to move through the fixed column 11 and the fixed shaft 12, thereby pushing the hinge frame 19 to move, and further pushing the compaction platform 13 to move. This can drive the compaction wheels 17 to move, thereby compacting the coal surface. At the same time, the scraper 14 also moves, and its movement can scrape the coal surface flat, making it more convenient to flatten. By controlling the forward and reverse rotation of the drive motor, the forward and backward movement of the compaction wheels 17 can be controlled, thereby compacting the coal surface reciprocally. Then, by turning on the vibration motor 21, the compaction platform 13 and the compaction wheels 17 can be vibrated, further compacting the coal surface, making the compaction degree of the coal surface higher. This makes the present utility model have high compaction efficiency, good compaction degree for the coal surface, and high flatness. It does not need to rely on manual shoveling and compacting, reducing the labor intensity and danger of workers, and making the actual use effect of the present utility model better.
