Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slag conveyer cleaning, in particular to a slag accumulation cleaning device for a slag conveyer. BACKGROUND

[0002] The slag conveyer is mainly used for separating solid matter of a certain particle size from a solid-liquid mixture. It is a continuous and efficient mechanical slag removal device, commonly used in sorting or solid-liquid separation occasions. The scraper slag conveyer has a simple structure and a slow speed, but because the traction chain and the scraper directly slide on the tank bottom, not only the resistance is large, but also the wear and tear during use is relatively serious. In addition, the scraper and the chain of the slag conveyer are made of wear-resistant and corrosion-resistant raw materials and need to have a certain strength and rigidity to prevent being bent or broken when a large particle of slag block falls and gets stuck.

[0003] For the related technology in the above, the inventor believes that in the actual use process of the existing scraper slag conveyer, due to the poor quality of the coal used in the power plant boiler, the long-term accumulation leads to a large increase in the amount of ash and slag, resulting in the phenomenon of slag accumulation at the tail of the scraper. It may seriously cause the slag conveyer to trip due to the accumulation of slag on the scraper, affecting the normal work of the unit load and the slag conveyer, and bringing inconvenience to the workers. In addition, a large amount of accumulated slag will reduce the solid-liquid separation efficiency and quality of the slag conveyer. CONTENT OF THE UTILITY MODEL

[0036] Reference Figure 1 and Figure 3 A first mounting plate 5 is fixedly connected to the inner wall of the slag removal shell 101, and a second mounting plate 6 is fixedly connected to the side wall of the mounting sleeve 21. The second mounting plate 6 is located on the side of the first mounting plate 5 away from the drive roller 25. A guide rod 7 is connected to the first mounting plate 5. The guide rod 7 is parallel to the mounting sleeve 21, and the other end of the guide rod 7 is connected to a limit block 8. The guide rod 7 passes through the second mounting plate 6 and is slidably connected to it. A connecting tension spring 9 is sleeved on the guide rod 7. One end of the connecting tension spring 9 is connected to the first mounting plate 5, and the other end is connected to the second mounting plate 6. Several abutment rods 26 are fixedly connected in parallel on the side of the mounting sleeve 21 near the drive roller 25. An abutment roller 29 is rotatably arranged on the side of the abutment rod 26 away from the mounting sleeve 21. The abutment roller 29 is pressed against the peripheral wall of the drive roller 25 under the action of the connecting tension spring 9.

[0037] Reference Figures 3-5 The oscillating assembly 3 is mounted on the sliding plate 22. The oscillating assembly 3 includes an oscillating scraper 31, a cleaning rubber scraper 32, a rotating shaft 33, an oscillating motor 34, a drive shaft 35, an oscillating rod 36, a drive sleeve 37, and a connecting rod 38. One side of the oscillating scraper 31 is rotatably mounted on the side of the sliding plate 22 outside the mounting sleeve 21. A rotating shaft 33 is located on opposite sides of the oscillating scraper 31, and the oscillating scraper 31 is rotatably connected to the sliding plate 22 via the rotating shaft 33. One of the rotating shafts 33 extends out of the sliding plate 22 and is fixedly connected to the oscillating rod 36, which is located in the same plane as the oscillating scraper 31. The oscillating motor 34 is connected to the sliding plate 22, and one end of the drive shaft 35 is drively connected to the output shaft of the oscillating motor 34. The end of the drive shaft 35 away from the oscillating motor 34 is rotatably connected to one end of the connecting rod 38. The connecting rod 38 is parallel to the rotating shaft 33, and the drive sleeve 37 is connected to the end of the connecting rod 38 away from the drive shaft 35. The oscillating scraper 31 has an installation groove 10 on the side away from the sliding plate 22, and the cleaning rubber scraper 32 is embedded in the installation groove 10.

[0038] Reference Figures 2-4 The flushing assembly 4 includes a flushing water tank 41, a water supply hose 42, a connecting manifold 43, flushing nozzles 44, and a flushing pump 45. The connecting manifold 43 is connected to one side of the oscillating scraper 31 via a connector and is arranged parallel to the cleaning rubber scraper 32. Several flushing nozzles 44 are connected to the connecting manifold 43, with their open ends facing the cleaning rubber scraper 32. The two ends of the water supply hose 42 are respectively connected to the flushing water tank 41 and the connecting manifold 43, and the flushing pump 45 is connected to the water supply hose 42.

[0039] Reference Figure 2 , Figure 4 and Figure 6 During the slag removal process of the slag remover body 1, the swing scraper 31, under the action of the clamping spring 23, adheres to the surface of the slag removal conveyor belt 102. The setting of the cleaning rubber scraper 32 reduces the possibility of the swing scraper 31 damaging the surface of the slag removal conveyor belt 102. The setting of the mounting groove 10 enables the detachable connection between the cleaning rubber scraper 32 and the swing scraper 31, facilitating the replacement and removal of the cleaning rubber scraper 32 by the operator. Figure 5 During the cleaning process of the slag removal conveyor belt 102, the oscillating motor 34 starts and drives the drive shaft 35 to rotate. The drive shaft 35 drives the drive sleeve 37 to rotate through the connecting rod 38. The drive sleeve 37 slides relative to the oscillating rod 36. Under the driving action of the drive sleeve 37, the oscillating rod 36 rotates about the rotating shaft 33. The oscillating scraper 31 oscillates back and forth about the rotating shaft 33 under the drive of the oscillating rod 36, thereby removing and cleaning the impurities on the surface of the slag removal conveyor belt 102.

[0040] Reference Figure 2 and Figure 3 While cleaning the slag removal conveyor belt 102, the drive motor 24 starts and drives the drive roller 25 to rotate. When the drive roller 25 rotates to the point where the end of the abutment rod 26 corresponds to the drive groove 28, the sliding plate 22 and the swing scraper 31 move away from the slag removal conveyor belt 102 and separate from it under the action of the connecting tension spring 9. This cycle is repeated so that the slag cleaning component 2 avoids the moving slag removal plate 103, thus preventing positional interference between the swing scraper 31 and the slag removal plate 103 during the slag cleaning process.

[0041] Reference Figure 3 and Figure 4When cleaning the slag removal conveyor belt 102, the flushing pump 45 is activated, spraying water from the flushing water tank 41 through the water delivery hose 42, connecting manifold 43, and flushing nozzle 44 onto the surface of the slag removal conveyor belt 102 undergoing slag removal, which helps to improve the cleaning effect of the slag removal conveyor belt 102. The setting of the abutment roller 29 reduces the possibility of wear caused by the abutment rod 26 on the surface of the drive roller 25.

[0042] The implementation principle of the slag cleaning device for a slag remover in this embodiment is as follows: During the slag removal process of the slag remover body 1, the swing scraper 31 is in contact with the surface of the slag removal conveyor belt 102 under the action of the clamping spring 23. During the cleaning process of the slag removal conveyor belt 102 surface, the swing motor 34 drives the swing scraper 31 to swing back and forth, thereby cleaning the impurities on the surface of the slag removal conveyor belt 102. At the same time as cleaning, the drive motor 24 is started, so that the slag cleaning component 2 avoids the moving slag removal plate 103, thus avoiding positional interference between the swing scraper 31 and the slag removal plate 103 during the slag cleaning process.

[0043] When cleaning the slag removal conveyor belt 102, the flushing pump 45 is started, spraying water from the flushing water tank 41 onto the surface of the slag removal conveyor belt 102 that is being cleaned, which helps to improve the cleaning effect of the slag removal conveyor belt 102.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
