Description

Technical Field

[0001] This utility model relates to the field of industrial equipment, and in particular to a slag discharge structure at the slag outlet of a slag cooler. Background Technology

[0002] A slag cooler is an advanced piece of equipment specifically designed for processing high-temperature slag. Its original design purpose was to solve the problem of difficult processing of high-temperature slag in industrial production. The main functions of a slag cooler include cooling, solidification, and separation. By using specific cooling media and solidification technology, the high-temperature slag is rapidly cooled and solidified for subsequent storage, transportation, and utilization.

[0003] Traditional boilers mostly use dry ash discharge. After the high-temperature ash is discharged, it is cooled and the heat is recovered by a ash cooler before being discharged from the ash cooler. It then flows into a hydraulic ash flushing ditch by gravity and is discharged into a ash pit by hydraulic flushing. It is then scooped out by a grab bucket and transported by truck to be landfilled. During the operation of the ash cooler, there is a height difference between the ash outlet and the hydraulic ash flushing ditch. This area is an open structure. After the high-temperature hot ash is discharged from the ash cooler, it flows into the ash ditch by gravity. The high-temperature hot ash comes into contact with the flushing water, and a large amount of fine ash in the hot ash is released under the action of water vapor. Water vapor and dust can easily enter the interior of the ash cooler and adhere to the surrounding equipment, resulting in a harsh environment around the ash cooler. In severe cases, it can cause machine failure. At the same time, a large amount of water vapor is released, causing a lot of fog on site, which seriously affects normal inspection and causes severe corrosion of the equipment in the boundary area.

[0004] Therefore, it is necessary to provide a new slag discharge structure for the slag outlet of a cold slag machine to solve the above-mentioned technical problems. Utility Model Content

[0014] Compared with related technologies, the slag discharge structure of the slag outlet of the cold slag machine provided by this utility model has the following beneficial effects:

[0015] I. Significantly improves environmental performance

[0016] Reduce dust and water vapor pollution: The closed design of the slag storage cylinder effectively avoids the pollution of the surrounding environment by the dust and water vapor generated during the discharge of high-temperature hot slag. The synergistic effect of the tilting plate, baffle and buffer components effectively prevents the tilting plate from swinging back and forth due to inertia after tilting, thereby preventing slag dust and water vapor from entering the slag cooler and improving the stability of the equipment.

[0017] Reduced equipment corrosion risk: By reducing the adhesion of moisture and dust, corrosion problems of surrounding equipment are significantly improved, extending equipment life and reducing maintenance costs.

[0018] II. Improve slag removal efficiency and stability

[0019] Optimize the slag discharge process: The guide plate design inside the slag storage cylinder ensures that the slag can fall smoothly onto the tilting plate, avoiding the accumulation of slag on the other side of the tilting plate and improving the slag discharge efficiency. At the same time, the ingenious connection between the tilting plate, connecting rod, and counterweight enables the slag to be automatically tilted and discharged when it accumulates to a certain amount, realizing automated slag discharge.

[0020] III. Easy to clean and maintain

[0021] Automated cleaning function: The cleaning mechanism enables automated cleaning of the bottom of the flip plate, effectively removing scale and dirt from the bottom of the flip plate and preventing water vapor and dust from entering the cold slag machine due to imbalance caused by scale buildup. At the same time, it also reduces the labor intensity and cost of manual cleaning. The sloping design of the cleaning plate and cover plate makes the cleaning process smoother and more efficient.

[0022] IV. Enhancing Overall Security

[0023] Reduced safety hazards: The enclosed slag discharge structure avoids direct contact between operators and high-temperature slag, reducing the risk of burns and other safety accidents;

[0024] Improved inspection conditions: By reducing interference from water vapor and dust, the fog on site is greatly reduced, improving the visibility of inspection personnel and increasing inspection efficiency and accuracy. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 5 A slag discharge structure for a slag outlet of a slag cooler is disclosed. The slag discharge structure includes: a slag storage cylinder 1, a tilting plate 4, a counterweight 6, a baffle 7, a buffer assembly, a cleaning plate 8, and a cleaning mechanism. The top of the slag storage cylinder 1 is connected to the slag outlet of the slag cooler, and the bottom of the slag storage cylinder 1 is connected to a flushing ditch 2. One side of the flushing ditch 2 is connected to a slag pool 3. The tilting plate 4 is located inside the slag storage cylinder 1, and a connecting rod 5 is installed inside the tilting plate 4. One end of the connecting rod 5 extends out of the outer wall of the slag storage cylinder 1 and is fitted with a counterweight 6. A baffle 7 is located on one side of the counterweight 6. A buffer assembly is installed between one side of the slag storage cylinder 1 and the counterweight 6 to prevent the counterweight 6 from swinging back and forth due to inertia after the tilting plate 4 is tilted. A cleaning plate 8 is located on the other side of the slag storage cylinder 1, with one side of the cleaning plate 8 having an inclined design. A cleaning mechanism is installed between the slag storage cylinder 1 and the cleaning plate 8, and the cleaning mechanism drives the cleaning plate 8 to clean the bottom of the tilting plate 4. The sludge buffer assembly includes: a slide rod 9, a spring 10, and a slide cylinder 11. A fixed plate 12 is fixedly connected to one side of the sludge storage cylinder 1. Slide cylinders 11 are fixedly connected to one side of the fixed plate 12 at equal intervals. Springs 10 are fixedly connected to the inner walls of the slide cylinders 11. A slide rod 9 is fixedly connected to one end of each spring 10. The slide rod 9 is slidably connected to the inner wall of the corresponding slide cylinder 11. The end of the slide rod 9 away from the corresponding spring 10 is fixedly connected to a baffle 7. A U-shaped connecting rod 13 is fixedly connected to the side of the baffle 7 away from the counterweight 6. A trapezoidal block 14 is fixedly connected to one end of the U-shaped connecting rod 13. A rectangular sleeve 15 is fixedly connected to the side of the sludge storage cylinder 1 closest to the counterweight 6. A rectangular slider 16 is slidably connected to the inner wall of the rectangular sleeve 15. A guide plate 22 is fixedly connected to the inner wall of the sludge storage cylinder 1. The guide plate 22 is inclined. The bottom end of the rectangular slider 16 is inclined and matches the inclined surface of the trapezoidal block 14.

[0034] It should be noted that the inner wall of the rectangular sleeve 15 is provided with a friction plate near the top. When the rectangular slider 16 is pressed upward by the trapezoidal block 14 to move to the highest point, the bottom end of the rectangular slider 16 contacts the friction plate inside the rectangular sleeve 15. The friction between the friction plate and the rectangular slider 16 is less than the weight of the rectangular slider 16 itself. This means that when the rectangular slider 16 moves upward to the highest point and the trapezoidal block 14 disengages from the inclined surface at the bottom of the rectangular slider 16, it will not immediately descend, but will descend slowly due to its own weight.

[0035] Please see Figure 4 and Figure 5 The cleaning mechanism includes: a hydraulic push rod 17, a limiting rod 18, and a limiting sleeve 19. The hydraulic push rod 17 is fixedly connected to the other side of the slag storage cylinder 1. The output end of the hydraulic push rod 17 is fixedly connected to the cleaning plate 8. The limiting rod 18 is symmetrically fixedly connected to the side of the cleaning plate 8 near the hydraulic push rod 17. The limiting sleeve 19 is fixedly connected to the other side of the slag storage cylinder 1. The limiting rod 18 and the inner wall of the corresponding limiting sleeve 19 are slidably connected. A plate groove is opened inside the side of the slag storage cylinder 1 near the cleaning plate 8. Springs 20 are fixedly connected at equal intervals to the inner wall of the plate groove. A cover plate 21 is slidably connected to the inner wall of the plate groove. The top ends of the springs 20 are fixedly connected to the bottom ends of the cover plate 21. The top end of the cover plate 21 is designed with a slope. The slope of the cover plate 21 is in contact with the slope of the cleaning plate 8.

[0036] It should be noted that: the slag storage cylinder 1 has a groove near the sludge removal plate 8. In the initial state, the sludge removal plate 8 is located inside the groove and is in contact with the inclined surface of the cover plate 21. One side of its inclined surface is not inserted into the slag storage cylinder 1 and will not affect the rotation of the flip plate 4.

[0037] The working principle of the slag discharge structure at the slag outlet of the cold slag machine provided by this utility model is as follows:

[0038] Slag enters slag storage cylinder 1:

[0039] After the high-temperature slag is discharged from the slag outlet of the slag cooler, it first enters the slag storage cylinder 1. The slag storage cylinder 1 is equipped with an inclined guide plate 22. The guide plate 22 ensures that the slag can fall smoothly onto the side of the tilting plate 4 near the baffle 7, avoiding the accumulation of slag on the other side of the tilting plate 4, which would affect the tilting operation.

[0040] Tilting plate 4 accumulates slag and flips over:

[0041] As slag is continuously discharged, the slag in the slag storage cylinder 1 gradually accumulates. When the slag accumulates to a certain amount, its gravity will cause the tilting plate 4 to tilt downwards. The tilting plate 4 is connected to the counterweight 6 through the connecting rod 5. Therefore, when the tilting plate 4 tilts, it will drive the counterweight 6 to rotate clockwise along the connecting rod 5.

[0042] At this time, the tipping plate 4 opens, and the slag on top falls from the bottom of the slag storage cylinder 1 into the slag flushing ditch 2 due to gravity. The water in the slag flushing ditch 2 flushes the slag into the slag pool 3, completing the slag discharge process.

[0043] Buffer component stabilizes the flip plate 4:

[0044] When the slag on top of the tilting plate 4 falls off, the tilting plate 4 will start to rotate in the opposite direction due to the gravity of the hammer 6. At this time, the hammer 6 will rotate counterclockwise along the connecting rod 5 and contact the baffle 7 on one side. Due to inertia, the hammer 6 will squeeze the baffle 7, causing the baffle 7 to drive the sliding rod 9 to slide inside the sliding cylinder 11. During the sliding process, the sliding rod 9 will compress the spring 10, which will play a buffering role. At the same time, the movement of the baffle 7 will also drive the U-shaped connecting rod 13 to move. The trapezoidal block 14 fixedly connected to the other end of the U-shaped connecting rod 13 moves with the movement of the U-shaped connecting rod 13 and squeezes the rectangular slider 16 to move upward inside the rectangular sleeve 15. The top of the inner wall of the rectangular sleeve 15 is provided with a friction plate. Its friction force is less than the weight of the rectangular slider 16, so that the rectangular slider 16 can slowly descend when it moves to the highest point.

[0045] When the hammer 6 presses the baffle 7 and rebounds due to inertia, the upward-moving rectangular slider 16 will block the hammer 6, further reducing the back-and-forth swing of the hammer 6. This helps to prevent the flipping plate 4 from swinging back and forth with the hammer 6, thereby blocking slag dust and water vapor from entering the slag cooler.

[0046] The cleaning mechanism scrapes away the scale buildup at the bottom of the flip plate 4:

[0047] After the hammer 6 comes to rest and is in a vertical position, the rectangular slider 16 slides downward in the rectangular sleeve 15 due to gravity and returns to the initial state. At this time, the hydraulic push rod 17 on the other side of the slag storage cylinder 1 is activated, and its output end pushes the cleaning plate 8 to move along the connecting rod 5 axially at the bottom of the flip plate 4.

[0048] One end of the cleaning plate 8 is designed with a bevel and contacts the bevel at the top of the cover plate 21. When the hydraulic push rod 17 pushes the cleaning plate 8 to move, the cleaning plate 8 will squeeze the cover plate 21 to move downward inside the plate groove and compress the spring 20. The limiting rod 18 fixedly connected to the other side of the cleaning plate 8 moves smoothly inside the limiting sleeve 19 to ensure the stability of the cleaning plate 8 during the movement. When the cleaning plate 8 moves to the other end of the connecting rod 5, the hydraulic push rod 17 begins to retract and drives the cleaning plate 8 to move in the opposite direction.

[0049] When the cleaning plate 8 moves above the cover plate 21, the spring 20 releases its elasticity, scraping off the dirt adhering to the surface of the cleaning plate 8. At this time, the cleaning plate 8 completes one scraping operation and waits for the next cleaning operation after the flipping plate 4 is unloaded.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
