Description

Technical Field

[0001] The utility model relates to the technical field of coke anti - fragmentation, and specifically relates to a coke anti - fragmentation falling and feeding device. Background Art

[0002] A coke anti - fragmentation falling and feeding device is a device specially designed to solve the problem that coke is prone to breakage during the falling process.

[0003] This device usually uses a buffer structure to slow down the falling speed of coke, thereby reducing the probability of coke breakage. For example, it may adopt a multi - stage buffer platform or special elastic materials to absorb the impact force of coke falling. At the same time, by reasonably designing the shape and angle of the feeding channel, it guides the coke to fall smoothly, avoiding breakage due to collision and friction.

[0004] It is widely used in industrial fields involving coke processing such as coking plants and steel plants. In coking plants, this device can be installed at positions such as coke yards and coke discharging ports of coke ovens to ensure the integrity of coke during transportation and storage. In steel plants, the coke anti - fragmentation falling and feeding device can be used in the blast furnace feeding system to improve the quality of coke entering the furnace, thereby improving the efficiency and quality of steel production.

[0005] In the process of coal processing, it is necessary to transfer the coke obtained from the processing of raw coal. During the transfer of coke, a coke falling and feeding device is required. The patent publication number CN206985078U discloses a coke falling and feeding device that can prevent coke from being damaged and broken. The device includes a belt conveyor and a chute. One end of the belt conveyor is arranged above the feeding port of the chute. The chute includes an upper cylinder with a wider cross - section and a lower cylinder with a narrower cross - section.

[0006] The above - mentioned existing technical solutions have the following defects: only an inclined plane and a baffle are simply set in the feeding device, which cannot buffer the falling of coke, and cannot achieve the effect of reducing breakage and fragmentation. Coke will still collide with the inclined plane and the baffle under the action of height and its own weight, causing the coke to be damaged and broken, and cannot effectively protect the integrity of coke, reducing the utilization rate of coke.

[0039] The working principle and usage process of the present utility model: When in use, when the coke in the storage bin 2 is full, start the first motor 115. The output end of the first motor 115 drives the gear 113 to rotate. The gear 113 drives the toothed belt 112 to rotate. The toothed belt 112 drives the L-shaped toothed plate 111 to move downward. The L-shaped toothed plate 111 drives the square plate 6, the supporting plate 5, the rotating column 4 and the storage bin 2 to move downward. When the limiting block 7 at the rear of the square plate 6 contacts the limiting plate 10 at the bottom of the rear side of the box body 9, turn off the first motor 115 and start the second motor 1113. The output end of the second motor 1113 drives the rotating plate 1112 to rotate. The rotating plate 1112 drives the pushing plate 1111 to move forward. The pushing plate 1111 drives the roller block 119 to move forward in the T-shaped groove 118. During the moving process, the roller of the roller block 119 pushes the top of the rear side of the storage bin 2. Under the action of the rotating column 4, the feeding port of the storage bin 2 will rotate downward. During the process of the feeding port of the storage bin 2 rotating downward, the coke slides down along the slope of the inclined block 3. When the coke is emptied, turn off the second motor 1113. The above movement trajectory enables the coke to have no falling and impact behaviors, so the coke can be discharged without damage.

[0040] In summary, for the anti-breakage and dropping device for coke, through the combined use of the discharge box 1, the storage box 2, the inclined block 3, the rotating column 4, the supporting plate 5, the square plate 6, the limiting block 7, the slider 8, the box body 9, the limiting plate and the lifting and pushing mechanism, it solves the problem that only a simple inclined surface and a baffle are provided in the dropping device, which cannot buffer the dropping of coke, cannot achieve the effect of reducing breakage and fragmentation, and the coke will still collide with the inclined surface and the baffle under the action of height and self-weight, causing breakage and fragmentation of the coke, and cannot effectively protect the integrity of the coke, reducing the utilization rate of coke.
