Description

Technical Field

[0001] This utility model belongs to the field of annular cooler technology. Specifically, this utility model relates to a sludge removal device for annular cooler water tank. Background Technology

[0002] To avoid dust pollution on-site, water-sealed annular coolers are currently the mainstream structure in sintering plants for steel companies. Annular cooler water-sealed structures, such as... Figure 1 As shown, it mainly consists of an upper water seal structure, a lower water seal structure, and a mechanical seal structure. Due to leakage problems in the mechanical seal, dust and small particles of sintered ore enter the lower water seal when the annular cooler is cooled by forced air. Since the lower sealing water tank and water tank are fixed, and the space between the lower sealing water tank and the lower sealing plate is narrow, it is impossible to clean it with tools.

[0003] A patent application (patent number 201010536616.2, published on August 28, 2013) discloses a sludge removal device for a liquid tank in an annular liquid tank and a gate-type sealing device. The annular liquid tank has a sludge removal port on its bottom plate, and a sludge removal hopper communicating with the port is located below it. Furthermore, the lower edges of the outer and inner side plates of the gate-type sealing device are respectively provided with several scraper blades arranged circumferentially, with a predetermined distance between the lower edge of each scraper blade and the bottom plate of the annular liquid tank. The sludge removal operation is performed in real time during the operation of the annular liquid tank, requiring no special manual operation. This achieves automatic removal of sludge from the liquid tank, thereby reducing the operating resistance of the annular liquid tank and fundamentally solving the problem, thus providing a reliable guarantee for the normal operation of the annular liquid tank and ensuring normal start-up under any operating conditions. Based on this, the present invention also provides an annular liquid tank with this sludge removal device.

[0004] In existing technologies, if the interior of the annular cooler is not cleaned for a long time, a large amount of material will accumulate and harden, increasing the operating resistance and current of the annular cooler. In severe cases, it can cause equipment damage and shutdown. To clean it, we can only wait until long-term maintenance, when we have to cut off the outer sealing plate of the lower sealing water tank and use an electric pick to remove it completely. This is time-consuming, difficult, and labor-intensive. Utility Model Content

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0021] Please see Figure 1-4 A sludge removal device for a ring cooler water tank is disclosed. The ring cooler 1 is equipped with a material conveying mechanism IV and a discharge system V. The ring cooler 1 is equipped with a water tank 4, and a lower water seal structure II is provided on the side of the water tank 4. The lower water seal structure II includes a lower sealing water tank 3 provided on the side of the water tank 4. A lower sealing plate 2 is provided in the lower sealing water tank 3. The material conveying mechanism IV is a scraper 10 provided on the lower sealing plate 2. The discharge system V is provided at the bottom of the water tank 4 and the lower sealing water tank 3. When the ring cooler 1 is running, the lower sealing plate 2 will move, which will drive the scraper 10 to move along the lower sealing water tank 3. The scraper 10 will scrape up the sludge deposited at the bottom of the lower sealing water tank 3 and the sludge accumulated on the side walls of the lower sealing water tank 3 and push it to the discharge system V. The discharge system V will discharge the transported sludge. The number of scraper 10 can be appropriately increased according to the amount of sludge generated in the lower sealing water tank 3 of the ring cooler 1 to achieve better cleaning effect.

[0022] The discharge system V includes a collection hopper 5 located at the bottom of the water tank 4 and the lower sealing water tank 3. The bottom of the collection hopper 5 is equipped with a mud inlet valve 6, a mud storage chamber 7, and a mud discharge valve 8. The bottom of the mud discharge valve 8 is equipped with a mud discharge pipe 9. The sludge scraped off by the scraper plate 10 enters the collection hopper 5. The collection hopper 5 is welded to the bottom of the water tank 4 and the lower sealing water tank 3. The sludge entering the collection hopper 5 passes through the mud inlet valve 6 into the mud storage chamber 7. When the sludge in the mud storage chamber 7 reaches a certain level, the mud discharge valve 8 can be manually opened, allowing the sludge to pass through the mud discharge valve 8 and the mud discharge pipe 9 and be discharged from the entire annular cooler 1 system. This process is repeated continuously to clean and remove the sludge, ensuring that the sludge in the lower sealing water tank 3 remains under control. The mud inlet valve 6 and the mud discharge valve 8 are connected to the collection hopper 5, the mud storage chamber 7, and the mud discharge pipe 9 via flanges. The mud inlet valve 6 is normally open, and the mud discharge valve 8 is normally closed.

[0023] The mud inlet valve 6 and the mud outlet valve 8 are electric semi-ball valves; other types of valves, such as gate valves, ball valves, and butterfly valves, are prone to jamming, failure to close tightly, leakage, and short lifespan. Electric semi-ball valves can effectively prevent these problems.

[0024] The mud discharge valve 8 is installed upside down; this can prevent sludge from accumulating and causing the valve to become unable to open.

[0025] The scraper 10 is welded to the lower sealing plate 2. The scraper 10 is L-shaped, and the side of the scraper 10 is provided with a welding plate 11 connected to the lower sealing plate 2. The L-shaped scraper 10 can increase the contact area between the bottom and the side and the inner wall of the lower sealing water tank 3, thereby improving the efficiency of scraping off sludge. By welding the scraper 10 to the lower sealing plate 2 through the welding plate 11, the strength of the connection can be improved, preventing the problem of breakage during the scraping of sludge.

[0026] The annular cooler 1 is provided with an upper water seal structure I, which includes an upper sealing water tank on the water cooler and an upper sealing plate located in the upper sealing water tank.

[0027] The annular cooler 1 is equipped with a mechanical seal structure III, which is a sealing ring installed on the annular cooler 1.

[0028] Working principle: When the annular cooler 1 is running, the lower sealing plate 2 drives the scraper plate 10 to move in the lower sealing water tank 3. The scraper plate 10 scrapes up the sludge deposited at the bottom of the lower sealing water tank 3 and the sludge accumulated on the two side walls of the lower sealing water tank 3, and pushes it to the discharge system V. The discharge system V discharges the transported sludge. The sludge scraped off by the scraper plate 10 enters the collection hopper 5. The collection hopper 5 is welded to the bottom of the water tank 4 and the lower sealing water tank 3. The sludge entering the collection hopper 5 enters the sludge storage chamber 7 through the sludge inlet valve 6. When the sludge in the sludge storage chamber 7 reaches a certain level, the sludge discharge valve 8 can be manually opened. The sludge passes through the sludge discharge valve 8 and the sludge discharge pipe 9 and is discharged from the entire annular cooler 1 system. The above process is repeated to continuously clean and remove sludge.

[0029] The technical advantages of this utility model are as follows: the structural design is simple and reasonable, easy to develop and manufacture, and low in cost. It effectively solves the problem of the inability to clean sludge in the existing ring cooler 1, and can achieve online cleaning without stopping the machine or manual cleaning, which reduces labor, lowers labor costs, improves equipment processes, and increases work efficiency. At the same time, centralized and fixed-point sewage discharge solves the on-site pollution problem caused by manual cleaning.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
