Description

Technical Field

[0001] The invention relates to the technical field of boiler dust removal devices, and in particular to a boiler dust removal device. Background Art

[0002] ‌A boiler is an energy conversion device that heats water or other fluids by burning fuel or electrical energy to produce steam or high-temperature water, which in turn provides thermal energy or converts it into mechanical energy. ‌A boiler consists of two parts: a "pot" and a "furnace". The "pot" is a pressurized part that holds water and steam, while the "furnace" is where the fuel is burned. A boiler can convert mechanical energy through a steam power unit, or convert mechanical energy into electrical energy through a generator.

[0003] The existing invention patent with the publication number "CN220135491U" is named a boiler dust removal device, including a boiler body, a support plate is provided on one side of the top surface of the boiler body, and a fixed plate is provided on the top surface of the support plate: the top surface of the fixed plate is slidably connected with a moving box, and the top inner wall of the moving box is provided with a driving motor, and the output end of the driving motor is provided with an electric telescopic rod, and the outer ring of one side of the output end of the electric telescopic rod is provided with a dust collector, and the bottom end of the electric telescopic rod is provided with a rotating block, and the outer ring of the rotating block is evenly provided with multiple groups of brushes. This boiler dust removal device can achieve the purpose of cleaning the dust on the inner wall of the smoke exhaust pipe by providing a rotating block, a brush and a driving motor, and can suck the cleaned dust through a vacuum cleaner, thereby avoiding the dust inside the smoke exhaust pipe from being discharged into the air to pollute the air, and also avoiding the time-consuming and labor-intensive manual cleaning by workers; The inventor believes that there are certain limitations in using a brush to clean only the smoke exhaust pipe without cleaning the inside of the boiler body. Due to the burning objects inside the boiler, the inner wall is not cleaned for a long time, which will cause insufficient combustion of the subsequent fuel. At the same time, it is necessary to cooperate with the brush during cleaning. However, the existing brush is placed in the boiler and the combustion cannot be effectively protected. Therefore, a boiler dust removal device is needed. Summary of the invention

[0030] In the present invention, the cleaning assembly includes a U-shaped cleaning tube 11 fixedly connected to the surface of the rotating plate 27, a plurality of shifting plates 12 are fixedly connected to the surface of the U-shaped cleaning tube 11, and a plurality of water outlet holes 24 are opened on the inner wall of the U-shaped cleaning tube 11.

[0031] By providing a plurality of water outlet holes 24 , the sprayed cleaning water passes through the plurality of water outlet holes 24 to clean the inner wall of the boiler body 1 .

[0032] In the present invention, the rotating plate 27 and the inner wall of the driving shaft 9 are provided with a same water supply groove 20 , and the water supply groove 20 is connected with the inner wall of the U-shaped cleaning pipe 11 .

[0033] By providing the water feeding trough 20 , cleaning water from the outside is fed into the U-shaped cleaning pipe 11 through the water feeding trough 20 for cleaning operation.

[0040] Working principle: when cleaning is needed after use, the motor 6 is started to drive the driving shaft 9 to rotate, and the driving shaft 9 drives the rotating plate 27 and the U-shaped cleaning tube 11 to rotate. At this time, the electric driving shaft 22 is started at the same time, and the rotation of the electric driving shaft 22 drives the driving wheel 23 to rotate. The driving wheel 23 drives the driven wheel 17 to reverse relatively through the high-temperature resistant eight-shaped belt 18, so that the first brush plate 14 and the third brush plate 15 originally located in the rotating plate 27 are rotated out of the rotating plate 27. After the surface of the first brush plate 14 contacts the surface of the trapezoidal baffle 28, the pair of trapezoidal baffles 28 are driven to move away from each other, and at this time, the second spring 26 is driven to stretch and lengthen to avoid the movement of the first brush plate 14. When the top of the second brush plate 13 contacts the inner wall of the boiler body 1, it is blocked and drives the second brush plate 13 to limit its position, so that the second brush plate 13 and the first brush plate 14 rotate. The rotation of the second brush plate 13 drives the connected first telescopic rod 29 to be subjected to force through the driving shaft 32, so that the first telescopic rod 29 is compressed and shortened together with the first spring 31. When the first brush plate 14 is vertically attached to the inner wall of the boiler body 1, the surface of the second brush plate 13 is attached to the inner wall of the boiler body 1, and the surface of the fourth brush plate 16 is attached to the inner wall of the boiler body 1. The driving shaft 9 rotates through the rotating plate 27 to drive the second brush plate 13 and the fourth brush plate 16 to rotate as a whole. In this process, one end of the upper water pipe 21 is immersed in clean water, and the water pump 7 is started to drive the clean water to be pumped into the fixed ring 8, and then transported to the U-shaped cleaning pipe 11 through the water delivery trough 20, and sprayed out through multiple water outlet holes 24, cooperating with the second brush plate 13 and the fourth brush plate 16 to clean the inner wall of the boiler body 1. After that, the sewage pipe 34 can be opened to discharge the clean sewage. With the above structure, when it is no longer cleaned, the second brush plate 13 and the fourth brush plate 16 are stored in the rotating plate 27 for protection, and the inner wall of the boiler body 1 can be cleaned during operation.
