Description

Technical Field

[0001] This utility model belongs to the field of flue ash storage technology, specifically relating to a large-capacity storage silo for smelting flue ash. Background Technology

[0002] In the metallurgical smelting process, equipment such as converters and blast furnaces generate a large amount of flue dust. This type of material is characterized by fine dust, strong stickiness, and easy caking. It is also often accompanied by a certain temperature and combustible components, which puts forward stringent requirements on the safety, sealing and unloading efficiency of storage equipment. As steel enterprises develop towards large-scale and intensive production, traditional small ash storage tanks can no longer meet the storage needs of large-scale production. Large-capacity storage silos are gradually becoming the mainstream choice in the industry because they can achieve centralized storage, reduce the frequency of transfer, and reduce the risk of secondary pollution.

[0003] However, existing large-capacity smelting flue ash storage silos still have significant technical defects in actual operation. The core problem is the difficulty of cleaning the ash accumulation on the inner wall. During the storage process, flue ash is easily adhered to the inner wall of the silo due to temperature changes, humidity, and the compression of the material itself. After long-term accumulation, it will harden and harden. This problem not only leads to a sharp reduction in the actual effective volume of the silo and reduces the storage capacity, but also causes problems such as poor material discharge and fluctuations in discharge speed during the ash discharge stage, which seriously affects the continuous operation efficiency of the production line.

[0004] To address the aforementioned issues, various improvement solutions have been proposed within the industry, but all exhibit significant limitations. Some technologies utilize vibration motors installed on the discharge plate or conical section of the storage silo to promote material descent and attempt to reduce residue. However, such solutions only apply to the lower discharge area of ​​the storage silo, offering little to no cleaning effect on the accumulated ash on the upper and middle cylinder walls. Furthermore, high-frequency vibrations can easily lead to fatigue damage to the storage silo structure. Another solution employs a nitrogen ring pipe to introduce inert gas, using airflow agitation to lower the material temperature and reduce scaling. However, its core function focuses on cooling and explosion prevention, with ash removal being merely a secondary effect of the airflow. It has a negligible ability to clean already adhered, caked ash.

[0005] In summary, existing cleaning technologies for smelting flue ash storage silos either have limitations in cleaning range, occupy storage space, or cannot coordinate with the ash discharge process, making it difficult to meet the actual needs of large-capacity storage silos for efficient, convenient, and safe cleaning of the inner wall ash. Therefore, developing a large-capacity storage silo structure that can simultaneously achieve full-range inner wall cleaning during the ash discharge process has become a key direction for solving industry pain points. Utility Model Content

[0006] The purpose of this invention is to provide a large-capacity storage silo for smelting flue ash, which allows for simultaneous cleaning of the silo's inner wall during ash discharge, preventing ash accumulation and caking, ensuring the effective volume of the silo, solving the problem of poor material discharge, and improving the continuity of the production line.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A large-capacity storage silo for smelting flue ash includes a storage silo body, an inlet pipe installed on the outer side of the storage silo body near the top, a discharge pipe provided at the bottom of the storage silo body, a guide rod fixed on the inner wall of the top of the storage silo body and arranged vertically downward, and a cleaning structure installed on the outer side of the guide rod.

[0009] The cleaning structure includes a sliding plate with a sliding groove at its center. The sliding plate is slidably connected to the outside of the guide rod through the sliding groove. Multiple cleaning blocks are slidably connected to the outside of the sliding plate, and a pushing structure is installed inside the sliding plate.

[0010] The pushing structure includes a mounting groove, which is disposed within the sliding plate. The cleaning block is slidably connected within the mounting groove. A limit plate is fixed to one end of the cleaning block inside the mounting groove. A central fixing block is fixed at the center of the mounting groove. A spring is installed between the central fixing block and each of the limit plates.

[0011] The cleaning block has a uniformly arranged scraping block at the end away from the sliding plate.

[0012] The inner wall of the sliding groove is also uniformly provided with abutment scraping blocks.

[0013] A mounting frame is installed on the top of the storage tank body. A rotating roller is rotatably connected inside the mounting frame. A pull rope is wound around the outside of the rotating roller, and the end of the pull rope away from the rotating roller extends into the storage tank body and is connected to the sliding plate. A motor is installed on the mounting frame, and the output end of the motor passes through the mounting frame and is connected to the rotating roller.

[0014] There are at least two sliding plates, and the cleaning blocks on the two sliding plates are staggered.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This invention can scrape off flue dust on the inner wall of the storage silo using a cleaning block, thereby cleaning the inner wall of the storage silo simultaneously during ash discharge, preventing ash accumulation and caking, ensuring the effective volume of the storage silo, solving the problem of poor material discharge, improving the continuity of the production line, and eliminating the need for a separate cleaning procedure, thus saving time and space, reducing equipment costs and structural damage risks, and adapting to the needs of large-capacity storage silos.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-5 As shown, a large-capacity storage silo for smelting flue dust includes a storage body 1. A feed pipe 16 is installed on the outer side of the storage body 1 near the top. A discharge pipe 2 is provided at the bottom of the storage body 1. Flue dust is discharged from the feed pipe 16 into the storage body 1. After being deposited in the storage body 1, it is discharged through the discharge pipe 2. Valves are provided on both the discharge pipe 2 and the feed pipe 16 to prevent flue dust from flowing back from the feed pipe 16 or leaking from the discharge pipe 2. A guide rod 3 is fixed on the inner wall of the top of the storage body 1 and is set vertically downward. A cleaning structure is installed on the outer side of the guide rod 3.

[0026] See attached document Figure 2 The cleaning structure includes a sliding plate 4, with a sliding groove 14 at its center. The sliding plate 4 is slidably connected to the outside of the guide rod 3 via the sliding groove 14. Multiple cleaning blocks 5 are slidably connected to the outside of the sliding plate 4. A pushing structure is installed inside the sliding plate 4. (See attached diagram) Figure 5The pushing structure includes an installation groove 11, which is set inside the sliding plate 4. The cleaning block 5 is slidably connected inside the installation groove 11. A limit plate 13 is fixed to one end of the cleaning block 5 inside the installation groove 11. A central fixing block 12 is fixed at the center of the installation groove 11. A spring 10 is installed between the central fixing block 12 and each limit plate 13. When unloading the flue ash inside the storage body 1, the flue ash is gradually discharged from the storage body 1, causing the sliding plate 4 to lose the support of the flue ash and gradually move downward. When the sliding plate 4 moves downward, it can drive the cleaning block 5 to move downward, so that the cleaning block 5 can scrape off the flue ash on the inner wall of the storage body 1, ensuring the cleaning effect. The setting of the limit plate 13 prevents the cleaning block 5 from completely moving out of the installation groove 11.

[0027] See attached document Figure 4 The cleaning block 5 is evenly provided with abutting scraping blocks 6 at the end away from the sliding plate 4, and abutting scraping blocks 6 are also evenly provided on the inner wall of the sliding groove 14. By setting the abutting scraping blocks 6, the abutting scraping blocks 6 can better clean the flue dust on the inner wall of the storage body 1, and can also clean the flue dust on the outside of the guide rod 3 when the sliding plate 4 moves down.

[0028] See attached document Figures 3-4 A mounting frame 15 is installed on the top of the storage body 1. A rotating roller 7 is rotatably connected inside the mounting frame 15. A pull rope 8 is wound around the outside of the rotating roller 7, and the end of the pull rope 8 away from the rotating roller 7 extends into the storage body 1 and is connected to the sliding plate 4. A motor 9 is installed on the mounting frame 15. The output end of the motor 9 passes through the mounting frame 15 and is connected to the rotating roller 7. When the motor 9 is driven, it can drive the rotating roller 7 to rotate, thereby enabling the rotating roller 7 to drive the pull rope 8 to be wound around the outside of the rotating roller 7, thereby pulling the sliding plate 4 to move upward. The motor 9 has a self-locking effect.

[0029] There are at least two sliding plates 4, and the cleaning blocks 5 on the two sliding plates 4 are staggered. With this arrangement, after the lower cleaning block 5 moves down to clean the inner wall of the storage body 1, the gap formed between each two cleaning blocks 5 can be cleaned by the upper cleaning block 5, so that the cleaning effect is thorough.

[0030] The working principle of this utility model is as follows: Before ash discharge, the motor 9 is driven first, so that the output end of the motor 9 drives the rotating roller 7 to rotate. Then, when the rotating roller 7 winds the pull rope 8, it pulls the sliding plate 4 upward until the sliding plate 4 contacts the top plate of the storage body 1. At this time, the flue ash can be discharged into the storage body 1. When the storage body 1 is full, the ash inside the storage body 1 can be discharged. After the ash inside the storage body 1 is discharged, the motor 9 is released from its self-locking, so that the sliding plate 4 moves downward, which can drive the cleaning block 5 to move downward. Then, the cleaning block 5 can scrape off the flue ash on the inner wall of the storage body 1, ensuring the cleaning effect. After the lower cleaning block 5 moves down and cleans the inner wall of the storage body 1, the gap formed between each two cleaning blocks 5 can be cleaned by the upper cleaning block 5, so that the cleaning effect is thorough.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
