Detailed Implementation
[0018] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.
[0019] Example: A converter primary dry dust removal, scale prevention, and evaporative cooling device, such as... Figures 1-2As shown, the assembly includes an evaporative cooler 1, a working frame 2, an inlet pipe 101, an outlet pipe 102, a first motor 3, a second motor 4, a first screw 5, a second screw 6, a connecting block 601, a third motor 8, a gear chain transmission mechanism 9, a descaling cutter 10, a connecting plate 11, and a scraper 12. The evaporative cooler 1 serves as the mounting carrier for the components. The working frame 2 is connected to the evaporative cooler 1. The working frame 2 has symmetrical rectangular guide grooves on its front and back. A circular guide groove is formed between the two rectangular guide grooves on the working frame 2. The left and right sides of the working frame 2 are rectangular in shape, while the middle part is cylindrical, which facilitates stable descaling operations. The right side of the working frame 2 is connected to... An air intake pipe 101 is provided. An air outlet pipe 102 is connected to the left side of the working frame 2. A first motor 3 is bolted to the right side of the working frame 2, located in front of the air intake pipe 101. A second motor 4 is bolted to the right side of the working frame 2, located behind the air intake pipe 101. A first screw 5 is rotatably connected to a rectangular guide groove on the front side of the working frame 2. The left end of the output shaft of the first motor 3 rotatably passes through the working frame 2 and is connected to the first screw 5 via a coupling. A second screw 6 is rotatably connected to a rectangular guide groove on the rear side of the working frame 2. The left end of the output shaft of the second motor 4 rotatably passes through the working frame 2 and is connected to the second screw 6 via a coupling. The screw 6 is connected to the first screw 5, and the left end of the first screw 5 is threadedly connected to the connecting block 601. The third motor 8 is mounted on the connecting block 601 by bolts. The gear chain transmission mechanism 9 is mounted on the connecting block 601. The gear chain transmission mechanism 9 consists of a mounting frame, gears, and a chain. The mounting frame is connected to the connecting block 601. Gears are symmetrically and rotatably connected to the left side of the mounting frame. The front gear on the mounting frame is connected to the output shaft of the third motor 8. A chain is wound between the two gears. The right side of the mounting frame on the gear chain transmission mechanism 9 is rotatably connected to the descaling tool 10. The descaling tool 10 is connected to the rear gear on the mounting frame of the gear chain transmission mechanism 9. The descaling tool 10 is located in the circular guide groove on the working frame 2. The descaling tool 10 is set as an annular descaling tool with an annular scale formation. The outer ring edge is evenly distributed with serrated blades for descaling operations. The left end of the second screw 6 is threadedly connected to the connecting plate 11. The connecting plate 11 is connected to the scraper 12. The scraper 12 is located to the left of the descaling tool 10. The scraper 12 has a semi-circular shape. The outer ring of the scraper 12 fits against the lower part of the inner part of the working frame 2 to facilitate the collection of scale. The third motor 8 is started to drive the descaling tool 10 to rotate. The first motor 3 and the second motor 4 are started to drive the descaling tool 10 and the scraper 12 to move. The descaling tool 10 scrapes off the scale inside the working frame 2.
[0020] like Figure 3As shown, it also includes a collection frame 13, a mounting plate 14, an electric push rod 15, and a baffle 16. The collection frame 13 is connected to the upper right side of the evaporative cooler 1. The collection frame 13 is located below the air inlet pipe 101. The collection frame 13 is inclinedly set on the lower right side of the working frame 2 to facilitate the collection of scale. The mounting plate 14 is welded to the upper right side of the evaporative cooler 1. The collection frame 13 is located above the mounting plate 14. The electric push rod 15 is installed on the mounting plate 14. The baffle 16 is slidably connected to the collection frame 13. The lower side of the baffle 16 is connected to the push rod on the electric push rod 15. The scraper 12 pushes the scraped scale into the collection frame 13. The electric push rod 15 is activated to drive the baffle 16 to move and discharge the scale.
[0021] When this device is needed, the electric push rod 15 is initially set to an extended state. High-temperature flue gas from the converter enters the working frame 2 through the inlet pipe 101. The third motor 8 is started, and the output shaft of the third motor 8 rotates, driving the gear chain transmission mechanism 9 to operate, causing the descaling cutter 10 to rotate. Then, the first motor 3 and the second motor 4 are started. The output shaft of the first motor 3 rotates, driving the first screw 5 to rotate. The first screw 5 drives the third motor 8, the gear chain transmission mechanism 9, and the descaling cutter 10 to move. The circular guide groove on the working frame 2 can guide the descaling cutter 10, allowing the descaling cutter 10 to scrape off the scale on the inner surface of the working frame 2. Simultaneously, the output shaft of the second motor 4 rotates, causing the moving block, connecting plate 11, and scraper 12 to shift. The scraper 12 can push the scale scraped off by the descaling blade 10 into the collection frame 13. The third motor 8 is turned off, and the output shafts of the first motor 3 and the second motor 4 are controlled to rotate in opposite directions, thereby driving the descaling blade 10 and scraper 12 to reset. This process is repeated. Then, the electric push rod 15 is started. The upper push rod of the electric push rod 15 shortens, causing the baffle 16 to move, so that the scale in the collection frame 13 falls into the off-site collection tool under the action of gravity. After collection, the upper push rod of the electric push rod 15 is extended, causing the baffle 16 to reset. The above operations can remove the scale inside the working frame 2.
