Description

Technical Field

[0001] This utility model relates to the field of quench tower desalination technology, specifically a device for desalination and scale removal from a hazardous waste quench tower. Background Technology

[0002] A Chinese utility model patent with publication number CN221649332U discloses a descaling device for a hazardous waste quenching tower. The device uses a wall scraping component and a flushing component to clean the scale adhering to the inner wall of the quenching tower. The wall scraping component scrapes off the scale adhering to the inner wall of the quenching tower, and after the scale is scraped off, the flushing component rinses the inner wall of the quenching tower to ensure a thorough cleaning of the inner wall of the quenching tower.

[0003] However, after long-term use, the scraping assembly develops gaps due to wear between the scraper and the tower wall, resulting in incomplete removal of salt scale and poor cleaning effect. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a descaling device for hazardous waste quench towers to solve the technical problems mentioned in the prior art.

[0005] A descaling device for a hazardous waste quench tower includes a fixed ring disposed inside the quench tower and a driving component that drives the fixed ring to reciprocate along the centerline of the quench tower. A scraper is disposed between the fixed ring and the inner wall of the quench tower. The scraper is mounted on the fixed ring by multiple sets of elastic elements.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-4 This utility model provides a descaling device for a hazardous waste quench tower, including a fixed ring 1 disposed inside the quench tower 17, and a driving component that drives the fixed ring 1 to reciprocate along the centerline of the quench tower 17. A scraper 2 is disposed between the fixed ring 1 and the inner wall of the quench tower 17. The scraper 2 is mounted on the fixed ring 1 by multiple sets of elastic elements. The elastic elements are in a compressed state to tightly fit the blade head of the scraper 2 against the inner wall of the quench tower 17, thereby ensuring that the blade head of the scraper 2 remains in contact with the inner wall of the quench tower 17 even when it wears during movement, thus scraping off the scale cleanly and improving the cleaning effect.

[0032] Furthermore, the scraper 2 includes several first short sections 3 and several second short sections 6. The first short section 3 is a hollow arc-shaped tube. A guide groove 4 is opened on the side of the first short section 3 near the inner wall of the quench tower 17, and a first cutter head 5 is respectively extended along the opening direction of the guide groove 4. The two ends of the second short section 6 are respectively inserted through the two ends of the first short section 3 or the adjacent ends of two adjacent first short sections 3 to form a ring structure on the outer periphery of the fixing ring 1. A second cutter head 7 is provided on the second short section 6. The second cutter head 7 passes through the guide groove 4 and is slidably installed between the opposite faces of two adjacent first cutter heads 5 to guide and limit the second cutter head 7. The outer rings of the first cutter head 5 and the second cutter head 7 are on the same ring to ensure that the first cutter head 5 and the second cutter head 7 contact the inner wall of the quench tower 17 simultaneously during movement, avoiding the situation where local scale cannot be scraped off. In the above description, the scraper 2 is tilted at 5-10° in the horizontal direction, which allows the scraped salt scale to slide off along the inclined surface, preventing a large amount of salt scale from accumulating on the scraper 2, causing rust and affecting its service life. It should be noted that a discharge groove 19 is provided at the bottom of the first short section 3 so that the salt scale scraped by the first cutter head 5 can be discharged from the discharge groove 19.

[0033] Furthermore, the driving components include a bidirectional reciprocating lead screw 8, a limiting rod 10, and a drive motor 12. The bidirectional reciprocating lead screw 8 passes through the lead screw thread groove 9 of the fixed ring 1, and its two ends extend to the upper and lower sides of the quench tower 17 respectively, and are rotatably connected to the inner wall of the quench tower 17 through a fixing member. The limiting rod 10 passes through the limiting hole 11 of the fixed ring 1, and its two ends extend to the upper and lower sides of the quench tower 17 respectively, and are connected to the inner wall of the quench tower 17 through a fixing member. Specifically, the fixing member is a bearing, and the outer ring of the bearing is connected to the inner wall of the quench tower 17 through a bearing seat. The bearing inner ring is fixedly connected to the inner wall of the bidirectional reciprocating screw 8 and the limiting rod 10 by a pin. The drive motor 12 is located on the outer periphery of the quench tower 17. The output shaft of the drive motor 12 passes through the inner wall of the quench tower 17 and is connected to a worm gear 13. The worm gear 13 meshes with a worm wheel 14 provided on the surface of the bidirectional reciprocating screw 8, so that the drive motor 12 drives the worm gear 13 to rotate, and then drives the bidirectional reciprocating screw 8 to rotate through the worm wheel 14, so as to drive the fixed ring 1 to move back and forth along the center line of the quench tower 17, thereby driving the scraper 2 to scrape off the salt scale adhering to the inner wall of the quench tower 17.

[0034] In the above, the elastic element is installed on the first short section 3 or the second short section 6, such as Figure 2As shown, in this embodiment, the fixing rod 15 is installed on the first short section 3. Specifically, the elastic element includes the fixing rod 15 and the spring 16. One end of the fixing rod 15 is connected to the scraper 2, and the other end passes through the fixing ring 1 and is connected to the limiting block 18. The spring 16 is provided on the fixing rod 15, and both ends of the spring 16 are connected to the opposite surfaces of the scraper 2 and the fixing ring 1, respectively. In the initial state, the spring 16 is adjusted to be in a compressed state. When the scraper 2 is worn, the spring 16 can press the scraper 2 against the inner wall of the quench tower 17 under the action of elastic restoring force, so as to realize the adaptive adjustment of the scraper 2. Further, the fixing rod 15 has a guide part and an adjusting part; the guide part is a rod body with a smooth surface, which is installed on the scraper 2 and slidably connected to the fixing ring 1; the adjusting part is a rod body with a threaded groove on the surface, and the limiting block 18 is threadedly installed on the adjusting part so as to adjust the compression of the spring 16 by means of the limiting block 18, and to remove the limiting block 18 so as to facilitate the disassembly and replacement of the scraper 2. The extension lines of multiple fixing rods 15 intersect the center of the fixing ring 1 at a point, which ensures that when the diameter of the scraper 2 expands / contracts, the outer ring of the scraper 2 is always on the same ring and in full contact with the inner wall of the quench tower 17.
