Description

Technical Field

[0001] This utility model relates to the field of buffer material discharge, specifically to a coke conveying buffer material discharge device. Background Technology

[0002] After coke is quenched, it is transported to the storage area by belt conveyor. According to the coke conveying system, the transfer process involves six transfers and drops via upper and lower belts, with a total drop height of 24 meters. There is a significant drop at the overlap of the upper and lower belt transfer points. This height difference causes the coke blocks to experience a large impact and collision when falling from the upper belt outlet to the lower belt, resulting in localized fragmentation and 3-4% powder damage to the coke product.

[0003] The breakage and pulverization of coke blocks can lead to several adverse effects: First, it reduces the strength and durability of the coke blocks, which may negatively impact subsequent metallurgical processes; second, excessive powder increases dust pollution during transportation and storage, potentially causing environmental and health problems; and third, since high-quality coke blocks are typically more expensive than powdered coke, this breakage directly results in economic losses.

[0004] Furthermore, frequent collisions and abrasions accelerate the wear and tear on conveyor equipment, increasing maintenance costs and downtime. This not only affects production efficiency but may also lead to additional economic losses. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a coke conveying buffer discharge device.

[0006] This utility model is achieved through the following technical solution:

[0007] A coke conveying buffer discharge device includes an upper belt and a lower belt that overlap at both ends. A buffer chamber is provided below the discharge port of the upper belt. A buffer plate is rotatably connected to the buffer chamber via a rotating shaft. The material received by the buffer plate and the counterweight block provided on its outer side act alternately around the rotating shaft to achieve the buffering action of the buffer plate moving up and down. The buffer plate is provided with several rotating buffers for receiving materials.

[0008] Furthermore, this application also proposes that the buffer plate is inclinedly installed in the buffer chamber, the bottom end of the buffer plate is movably connected to the lower baffle fixed in the buffer chamber, and the upper part of the rotating shaft is provided with an upper baffle fixed in the buffer chamber for blocking materials.

[0009] Furthermore, this application also proposes that the two ends of the rotating shaft extend to the outside of the buffer chamber and are fixedly connected to the counterweight via connecting rods.

[0010] Furthermore, this application also proposes that the rotary buffer includes a rotary shaft, the circumferential surface of which is connected and fixed to the sleeve by a plurality of buffer springs.

[0011] Furthermore, this application also proposes that a number of strip-shaped holes are evenly opened on the buffer plate, and a support block is connected to both ends of each strip-shaped hole, and the two support blocks are rotatably connected to the rotating shaft.

[0012] Furthermore, this application also proposes that the bottom discharge port of the buffer bin is directly opposite the lower conveyor belt, and the buffer bin is supported and fixed by a support frame.

[0013] Compared with existing technologies, the beneficial effects of this utility model are: by setting buffer bins, buffer plates and rotary dampers at the transfer points of the coke conveyor belt, this utility model effectively reduces the impact of falling coke blocks, and has the advantages of reducing coke block breakage and pulverization, improving coke quality, reducing dust pollution and reducing economic losses.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1 As shown, a coke conveying buffer unloading device includes an upper belt 1 and a lower belt 2 that overlap at their ends. A buffer chamber 3 is provided below the discharge port of the upper belt 1. The buffer chamber 3 is designed to provide a buffer space between the upper belt 1 and the lower belt 2 to reduce the impact force when coke falls from the discharge port of the upper belt to the lower belt. A buffer plate 4 is rotatably connected to the buffer chamber 3 through a rotating shaft 5. The buffer plate 4 is connected to the buffer chamber through the rotating shaft 5, so that the buffer plate can perform up and down buffering action under the gravity of the material and the action of the counterweight. This design can effectively absorb and disperse the impact energy when the material falls, thereby reducing the breakage of the coke.

[0020] The material received by the buffer plate 4 and the counterweight 7 set on its outer side work alternately around the rotating shaft 5 to realize the up and down buffering action of the buffer plate 4. The buffer plate 4 is equipped with several rotating buffers 41 to receive materials. The design of the rotating buffers 41 is to further enhance the buffering effect.

[0021] Specifically, when coke falls from the discharge port of the upper conveyor belt 1 onto the buffer plate inside the buffer bin 3, the coke no longer falls directly onto the lower conveyor belt 2 after entering the buffer bin 3, but accumulates on the buffer plate 4. Since the buffer plate and the counterweight are connected by a rotating shaft 5, this up-and-down movement forms a buffer cycle, effectively absorbing and dispersing the impact energy of the falling material. The rotary damper, through the combination of a rotating shaft and a buffer spring, further enhances this buffering effect, greatly reducing the impact force on the coke during its fall.

[0022] like Figure 1 As shown, the buffer plate 4 is inclinedly installed inside the buffer chamber 3. The bottom end of the buffer plate 4 is movably connected to the lower baffle 8 fixed inside the buffer chamber 3. An upper baffle 9, fixed inside the buffer chamber 3, is installed on the upper part of the rotating shaft 5 to block materials. The inclined installation of the buffer plate 4 helps to better disperse the impact force of the materials and reduce local fragmentation of the materials during the fall. The movable connection between the bottom end of the buffer plate 4 and the lower baffle allows the buffer plate to have a certain buffering space when impacted, further reducing material fragmentation. The upper baffle on the upper part of the rotating shaft serves to block materials and prevent them from damaging the rotating shaft 5.

[0023] like Figure 1 As shown, both ends of the rotating shaft 5 extend to the outside of the buffer chamber 3 and are fixedly connected to the counterweight 7 via the connecting rod 6.

[0024] like Figure 2 , 3 As shown, the rotary damper 41 includes a rotary shaft 43, and the circumferential surface of the rotary shaft 43 is connected and fixed to the sleeve 44 by a number of buffer springs 45. By utilizing the combination of the rotary shaft 43 and the buffer springs 45, the impact force of the coke block during the falling process is effectively absorbed and dispersed, thereby reducing the breakage of the coke block and the generation of powder.

[0025] like Figure 2 As shown, the buffer plate 4 has several strip holes 42 evenly distributed on it. Each strip hole 42 is connected to two ends of a support block 46. The two support blocks 46 are rotatably connected to the rotating shaft 43. The design of the strip holes 42 and the support blocks 46 on the buffer plate 4 allows the rotating shaft 43 to rotate within the strip holes through the support blocks 46, thereby realizing the up and down buffering action of the buffer plate.

[0026] like Figure 1As shown, the bottom outlet of the buffer bin 3 is directly opposite the lower conveyor belt 2. The buffer bin 3 is supported and fixed by the support frame 10. This design ensures the stability of the buffer bin 3 during the conveying process. The support frame 10 not only provides the necessary support force, but also ensures the stability and reliability of the buffer bin under various working conditions.

[0027] The implementation principle of a coke conveying buffer unloading device according to an embodiment of this application is as follows:

[0028] When coke falls from the discharge port of the upper belt 1 onto the buffer plate 4 in the buffer bin 3, it will accumulate on the buffer plate 4. When the accumulation reaches a certain amount, its weight exceeds the weight of the counterweight 7 at the pivot point of the rotating shaft 5. The buffer plate 4 will slowly move downward and separate from the lower baffle 8. The buffer plate 4 moves downward under the gravity of the coke material, while the counterweight moves upward. The material on the buffer plate 4 will fall onto the lower belt 2. At this time, the buffer plate 4 will quickly move upward under the gravity of the counterweight 7 and fit against the lower baffle 8.

[0029] This creates a buffer loop that effectively absorbs and disperses the impact energy of falling materials. Simultaneously, multiple rotating dampers 41 on the buffer plate 4 rotate via the rotating shaft 43 under the impact of the material. Furthermore, under the action of the buffer spring 45, the outer sleeve 44 undergoes a buffering deformation due to the impact, further enhancing the buffering effect. This significantly reduces the impact force on the coke during its fall. The combination of the rotating shaft 43 and the buffer spring 45 effectively absorbs and disperses the impact force on the coke blocks during their fall, thereby reducing the breakage and powder generation of the coke blocks.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
