DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Reference Figures 1 - 4 , an anti-blocking flue gas desulfurization device, including an absorption tank 1 and a first housing 2, and the absorption tank 1 and the first housing 2 are connected by a connecting pipe. One side of the first housing 2 is fixed with a second housing 3 by bolts. A fixing frame 7 is fixed between the first housing 2 and the second housing 3 by bolts. A rotating shaft 9 is rotatably connected to the top of the fixing frame 7. External flue gas enters the absorption tank 1 and reacts with the alkaline substances in the absorption tank 1 for desulfurization treatment. A motor is fixed to the bottom of the fixing frame 7 by bolts, and one end of the output shaft of the motor passes through the fixing frame 7 and is fixed to the rotating shaft 9. Two fixing rods 12 are fixed to both sides of the rotating shaft 9 by bolts. A sliding groove 15 is formed inside the fixing rod 12. A slider 16 is slidably connected in the sliding groove 15. The slider 16 can limit the moving distance of the sliding rod 13 to prevent the sliding rod 13 from completely moving out of the fixing rod 12. A sliding rod 13 is fixed to one side of the slider 16 by bolts. A spring 17 is welded to one side of the slider 16, and the spring 17 is fixed to the fixing rod 12. One end of the sliding rod 13 passes through the fixing rod 12 and is fixed to a scraper 10 by bolts, and the scraper 10 is in contact with the inner walls of the first housing 2 and the second housing 3. When the motor rotates, the rotating shaft 9 drives the fixing rod 12 to rotate, so that the sliding rod 13 drives the scraper 10 to rotate to clean the impurities attached to the inner walls of the first housing 2 and the second housing 3. At the same time, under the action of the spring 17, the slider 16 is continuously pushed, so that the scraper 10 is closely attached to the first housing 2 and the second housing 3.

[0024] In the present utility model, it should be noted that an air outlet pipe 6 is fixed to the tops of the first housing 2 and the second housing 3 by bolts. A collection box 4 is threadedly connected to the bottom ends of the first housing 2 and the second housing 3. The collection box 4 can collect the cleaned impurities, which is convenient for the staff to conduct centralized treatment. A brush holder 14 is fixed to the top end of the rotating shaft 9 by bolts. A filter box 11 is fixed to the top between the first housing 2 and the second housing 3 by bolts, and the bottom of the filter box 11 is in contact with the brush holder 14. When the rotating shaft 9 rotates, the brush holder 14 rotates to clean the filter box 11. A conical shell 8 is fixed to the top of the fixing frame 7 by bolts. The conical shell 8 can make the fallen impurities fall downward along its inclined surface to prevent the impurities from accumulating. A rubber ring 5 is adhered to the outside of the collection box 4. The rubber ring 5 can increase the friction at the bottom of the collection box 4, which is convenient for the staff to disassemble.

[0025] Working principle: When it is necessary to clean the inner walls of the first housing 2 and the second housing 3, first start the motor. The motor rotates to drive the rotating shaft 9 to drive the fixing rod 12 to rotate, so that the sliding rod 13 drives the scraper 10 to rotate to clean the impurities attached to the inner walls of the first housing 2 and the second housing 3. At the same time, the spring 17 continuously pushes the slider 16 to make the scraper 10 in close contact with the first housing 2 and the second housing 3. Then the cleaned impurities fall into the collection box 4 for collection.

[0026] In addition, the terms "install", "set", "connect", and "socket" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components, or constituent parts. Those of ordinary skill in the art can understand the specific meanings of the above terms in this application according to specific circumstances.
