Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of biomass power generation, in particular to a cleaning device for a biomass power generation combustion furnace. Background Technique
[0002] A biomass power generation combustion furnace is an energy conversion device that inputs biomass fuel into a boiler to convert it into electric energy. A large amount of dust generated during the combustion of biomass fuel adheres to the furnace wall, resulting in heat loss and uneven furnace conduction capacity. The temperature inside the combustion furnace is very high, and the combustion furnace is unevenly heated, which may cause phenomena such as furnace explosion. Therefore, it is necessary to regularly clean the inner wall of the combustion furnace with liquid.
[0003] Currently, the existing cleaning is usually done manually using brooms, dust collectors, etc. Since the diameter of the combustion furnace is smaller than the inner diameter of the furnace, when the broom and dust collector enter the furnace, they cannot be bent, making it difficult to remove the dust adhering to the side wall of the combustion furnace. For this reason, we have proposed a cleaning device for a biomass power generation combustion furnace. Content of the Utility Model
[0004] The purpose of the utility model is to provide a cleaning device for a biomass power generation combustion furnace to solve the above-mentioned technical deficiencies.
[0005] To achieve the above purpose, the utility model provides a cleaning device for a biomass power generation combustion furnace, including a connecting column. The bottom of the connecting column is connected to a rotating rod through a hinge seat. The bottom of the rotating rod is hinged to a cleaning plate, and uniformly distributed brushes are provided on the cleaning plate. The connecting column is connected to a U-shaped plate through a support rod. An auxiliary rod is provided inside the U-shaped plate. Both ends of the auxiliary rod are connected to the inner wall of the U-shaped plate through bearings. A pulley I is fixedly provided on the auxiliary rod. A support plate is provided at the top of the connecting column. A pulley II is connected to the support plate through a bearing. One end of a pull rope is fixedly connected to the pulley II, and the other end of the pull rope is wound around the pulley I and then fixedly connected to the surface of the rotating rod. A circular plate is fixedly connected to the pulley II. A limiting hole is provided on the circular plate, and a limiting rod is provided inside the limiting hole. A limiting groove for cooperating with the limiting rod is provided on the support plate.
[0006] Preferably, a rotating handle is provided on the circular plate, and an auxiliary handle is provided on the connecting column.
[0007] Preferably, the diameters of the circular plate and the support plate are both larger than that of the pulley II.
[0008] Preferably, the hinging direction of the rotating rod is perpendicular to the hinging direction of the cleaning plate.
[0009] The beneficial effects of the present utility model are as follows: After the connecting column and the rotating rod enter the combustion furnace, the circular plate is rotated by turning the handle, so that the pulling rope is wound around the second pulley. When the pulling rope is wound, it will pull the rotating rod to rotate, thereby changing the angle of the rotating rod, so that the cleaning plate can be close to and fit the inner wall of the combustion furnace, and then the connecting column is continuously reciprocated from bottom to top to clean the inner wall of the combustion furnace.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0016] Refer to Figures 1 - 3, this embodiment provides a cleaning device for a biomass power generation combustion furnace, including a connecting column 1. The bottom of the connecting column 1 is connected to a rotating rod 3 through a hinge seat 2. The bottom of the rotating rod 3 is hinged to a cleaning plate 4, and uniformly distributed brushes 5 are provided on the cleaning plate 4. A U-shaped plate 7 is connected to the connecting column 1 through a support rod 6. An auxiliary rod 8 is arranged inside the U-shaped plate 7. Both ends of the auxiliary rod 8 are connected to the inner wall of the U-shaped plate 7 through bearings. A pulley 9 is fixedly arranged on the auxiliary rod 8. A support plate 10 is arranged at the top of the connecting column 1. A pulley 11 is connected to the support plate 10 through a bearing. One end of a pull rope 12 is fixedly connected to the pulley 11, and the other end of the pull rope 12 is wound around the pulley 9 and then fixedly connected to the surface of the rotating rod 3. A circular plate 13 is fixedly connected to the pulley 11. A limiting hole 14 is arranged on the circular plate 13, and a limiting rod 15 is arranged in the limiting hole 14. A limiting groove 16 for cooperating with the limiting rod 15 is arranged on the support plate 10.
[0017] A rotating handle 17 is arranged on the circular plate 13. By holding the rotating handle 17 and rotating the circular plate 13 to make the pulley 11 rotate, an auxiliary handle 18 is arranged on the connecting column 1, and the connecting column 1 is moved up and down through the auxiliary handle 18.
[0018] The diameters of both the circular plate 13 and the support plate 10 are larger than that of the pulley 11 to ensure the normal use of the limiting rod 15.
[0019] The hinging direction of the rotating rod 3 is perpendicular to the hinging direction of the cleaning plate 4, ensuring that after the rotating rod 3 changes the angle, the cleaning plate 4 can still fit the inner wall of the combustion furnace to ensure the cleaning effect.
[0020] When the utility model is in use, after the connecting column 1 and the rotating rod 3 enter the combustion furnace, the circular plate 13 is rotated by rotating the rotating handle 17, so that the pull rope 12 is wound around the pulley 11. When the pull rope 12 is wound, it will pull the rotating rod 3 to rotate, thereby changing the angle of the rotating rod 3, and then the cleaning plate 4 can be close to and fit the inner wall of the combustion furnace. Then, the connecting column 1 is continuously reciprocated from bottom to top to clean the inner wall of the combustion furnace.
