Description

Technical Field

[0001] This utility model relates to the field of carbonization tower cleaning technology, specifically a peeling carbonization tower scale removal device. Background Technology

[0002] Currently, the removal of scale from the inner wall of a carbonization tower is mostly done using scrapers or brushes. For example, Chinese patent CN220216109U discloses a device for removing crystals inside an ammonium bicarbonate carbonization tower, which uses a scraper to remove scale; Chinese patent CN213670682 discloses a device for removing crystals inside an ammonium bicarbonate carbonization tower, which uses a brush to remove scale. However, since both scrapers and brushes are consumable parts and are installed inside the carbonization tower, it is difficult to replace them. As a result, the scrapers or brushes gradually reduce their cleaning effect due to wear and tear over long-term operation. To address the above issues, this paper proposes a technological innovation based on the existing peeling-type carbonization tower scale removal device. Utility Model Content

First threaded holes are evenly distributed on the top of the carbonization tower 1, and the first bolt 19 is screwed into the first threaded holes. The flange ring 18 is fixed to the top of the carbonization tower 1 by the first bolt 19, thereby fixing the cover 17 to the top of the carbonization tower 1. A lifting ring 3 is slidably installed inside the cover 17. An installation ring 31 is fixedly installed on the outer ring of the lifting ring 3. A first scraping ring 34 and a second scraping ring 35 are fixedly installed on the upper and lower sides of the installation ring 31, respectively. A first threaded ring 34 is evenly distributed on the inner wall of the lifting ring 3. The inner wall of the mounting ring 31 is uniformly provided with second threaded holes. A third bolt 32 is rotatably installed in the first through hole and screwed into the second threaded hole. The bottom of the cover 17 and the flange ring 18 are attached to the top of the carbonization tower 1. The top of the mounting ring 31 is uniformly provided with chip removal grooves 33. The first scraper ring 34 and the second scraper ring 35 are located outside the chip removal grooves 33. The outer walls of the first scraper ring 34, the mounting ring 31 and the second scraper ring 35 are attached to the inner wall of the cover 17 and correspond to the inner wall of the carbonization tower 1. The mounting ring 31 is fixed to the outer ring of the lifting ring 3 by the third bolt 32. When the lifting ring 3 moves up and down, it will drive the second scraper ring 35 and the first scraper ring 34 to move synchronously through the mounting ring 31. When the first scraper ring 35 moves downward, it will remove and peel off the scale inside the carbonization tower 1. When the first scraper ring 34 moves upward, it will remove and peel off the scale inside the carbonization tower 1. The scale peeled off by the first scraper ring 34 will slide down the surface of the first scraper ring 34 into the chip discharge groove 33 and fall through the chip discharge groove 33. The top of the cover 17 is evenly provided with two sets of second through holes, and a sealing ring 36 is fixedly installed in the second through holes. The top of the lifting ring 3 is evenly provided with two sets of connecting rods 15. The top of the connecting rods 15 passes through the two sets of sealing rings 36 and is located above the cover 17. The sealing rings 36 seal the connection gap between the connecting rods 15 and the cover 17. The top of the two sets of connecting rods 15 is fixedly provided with connecting plates 14. The top of the cover 17 Two sets of connecting sleeves 22 are evenly fixedly installed on the carbonization tower 1. A second bolt 23 is rotatably installed inside the connecting sleeve 22. A third threaded hole 2 and a fourth threaded hole 21 are opened on the front side of the connecting rod 15. The third threaded hole 2 is located above the fourth threaded hole 21. The second bolt 23 is screwed into the fourth threaded hole 21 and corresponds to the third threaded hole 2. A set of hydraulic rods 13 is fixedly installed on both the left and right sides of the carbonization tower 1. The two sets of hydraulic rods 13 use closed-loop feedback control technology to achieve synchronous operation. Closed-loop feedback control technology is a relatively mature technology nowadays, and will not be elaborated on here. The telescopic ends of the two sets of hydraulic rods 13 are fixedly installed at the bottom of the connecting plate 14. Support feet 11 are evenly fixedly installed on the outer wall of the carbonization tower 1. A discharge valve 12 is fixedly installed at the bottom of the carbonization tower 1.After opening the discharge valve 12, the detached scale can be discharged from the carbonization tower 1. The top of the cover 17 is connected to and fixedly equipped with an inlet valve 16.

[0016] Working principle: The flange ring 18 is fixed to the top of the carbonization tower 1 by the first bolt 19, thereby fixing the cover 17 to the top of the carbonization tower 1. The mounting ring 31 is fixed to the outer ring of the lifting ring 3 by the third bolt 32. The connecting plate 14 is driven to move up and down by the hydraulic rod 13. The connecting plate 14 drives the lifting ring 3 to move up and down by the connecting rod 15. When the lifting ring 3 moves up and down, it drives the second scraper ring 35 and the first scraper ring 34 to move synchronously through the mounting ring 31. When the second scraper ring 35 moves downward, it will remove and peel off the scale inside the carbonization tower 1. When the first scraper ring 34 moves upward, it will remove and peel off the scale inside the carbonization tower 1. The scale peeled off by the first scraper ring 34 will slide down the surface of the first scraper ring 34 into the chip discharge groove 33 and fall through the chip discharge groove 33. After the discharge valve 12 is opened, the peeled scale can be discharged from the carbonization tower 1.

[0017] When the lifting ring 3 is idle, the second bolt 23 is threaded through the connecting sleeve 22 and screwed into the fourth threaded hole 21 to fix the connecting rod 15 to the cover 17. At this time, the lifting ring 3, the first scraper ring 34 and the second scraper ring 35 are all located inside the cover 17. By fixing the connecting rod 15 to the cover 17, the lifting ring 3 can be prevented from falling suddenly and damaging the carbonization tower 1 during the idle process of the lifting ring 3 due to the failure of the hydraulic rod 13. When the first scraper ring 34 and the second scraper ring 35 need to be replaced due to wear, simply unscrew the first bolt 19, and then move the cover 17 upward along the connecting rod 15. After the connecting sleeve 22 is aligned with the third threaded hole 2, screw the second bolt 23 into the third threaded hole 2 to fix the cover 17 in the air. At this time, the third bolt 32 can be unscrewed, and then the mounting ring 31 can be moved upward to separate from the lifting ring 3, so that the mounting ring 31, together with the first scraper ring 34 and the second scraper ring 35, can be removed and replaced.
