[0023] The effect achieved by the entire Embodiment 1 is that during the chemical cleaning of the boiler, first, the chemical agents used for cleaning are stored in two storage tanks 410 in liquid form. The two storage tanks 410 are respectively threadedly connected to the tops of two first side frames 405. When the two second side frames 408 are inserted into the boiler body 1 and initially abut against the inner bottom of the boiler, the inner side of the first fixing ring 201 fits against the outer surface of one side of the boiler body 1. Through the rotational action of the hinge, the second fixing ring 202 rotates towards the first fixing ring 201, so that the side of the second fixing ring 202 fits against the other surface of the boiler body 1. The supporting bolts are sequentially inserted into the first fixing block 203 and the second fixing block 204 and rotated, so that the two fixing rings are tightly fixed on the outer surface of the boiler body 1. The mounting cross plate 401 can be supported by the support rod 205. The two electric telescopic rods 411 are synchronously started, and their telescopic ends drive the piston blocks 412 to move slowly downward in the corresponding storage tanks 410, playing a pressurizing role. The stored chemical agents uniformly flow into the first side frames 405 and the extension blocks 414, and are sprayed out from a plurality of first atomizing nozzles 406 and second atomizing nozzles 413. At the same time, the motor 402 is started, and the output end of the second motor 402 drives the rotating rod 403 to rotate synchronously, so that the chemical agents can be evenly sprayed on the inner wall of the boiler. Similarly, the second side frames 408 symmetrically fixed on the surface of the rotating rod 403 rotate synchronously. When the plurality of cleaning brushes 409 rub against the inner wall of the boiler, they will evenly smear the sprayed chemical agents, so that they can fully contact the scale on the inner wall of the boiler and react. Stop the rotation of the motor 402 and the extension of the electric telescopic rod 411. After waiting for the chemical agents to fully react with the scale, start the motor 402 again, so that the two second side frames 408 rotate rapidly in the boiler, and the plurality of cleaning brushes 409 will continuously rub against the inner wall of the boiler to clean the loosened or dissolved scale, avoiding the risk of injury to personnel when they need to hold a spray bottle and reach into the boiler to spray the chemical agents, thus improving the safety of the boiler chemical cleaning device.

[0024] Embodiment 2 is as Figures 1 - 4 shown. Both the first fixing ring 201 and the second fixing ring 202 are located at positions near the top of the outer surface of the boiler body 1, and the inner surfaces of the first fixing ring 201 and the second fixing ring 202 both fit against the outer surface of the boiler body 1.

[0025] The effect achieved by the entire Embodiment 2 is that during fixation, rubber pads are provided on the relative inner arc surfaces of the first fixing ring 201 and the second fixing ring 202. When the two fixing rings are tightly fitted on the boiler surface during the connection by bolts, the two rubber pads are squeezed, causing them to deform. The deformed rubber pads fill the space between the two fixing rings and the boiler body 1, increasing the frictional force between the two fixing rings and the boiler body 1 and improving the fixing effect of the boiler chemical cleaning device.

[0026] Working principle: During the chemical cleaning of the boiler, first, the chemical agents used for cleaning are stored in two storage tanks 410 in liquid form. The two storage tanks 410 are respectively threadedly connected to the tops of two first side frames 405. When the two second side frames 408 are inserted into the boiler body 1 and initially touch the inner bottom of the boiler, the inner side of the first fixing ring 201 fits against the outer surface of one side of the boiler body 1. Through the rotational action of the hinge, the second fixing ring 202 rotates towards the first fixing ring 201, so that the side of the second fixing ring 202 fits against the other surface of the boiler body 1. Then, the matching bolts are sequentially inserted into and rotated in the first fixing block 203 and the second fixing block 204, so that the two fixing rings are tightly fixed on the outer surface of the boiler body 1. The mounting cross plate 401 can be supported by the support rod 205. Two electric telescopic rods 411 are synchronously started, and their telescopic ends drive the piston blocks 412 to slowly move downward in the corresponding storage tanks 410, playing a pressurizing role. The stored chemical agents uniformly flow into the first side frames 405 and the extension blocks 414, and are sprayed out from multiple first atomizing nozzles 406 and second atomizing nozzles 413. At the same time, the motor 402 is started, and the output end of the second motor 402 drives the rotating rod 403 to rotate synchronously, so that the chemical agents can be evenly sprayed on the inner wall of the boiler. Similarly, the second side frames 408 symmetrically fixed on the surface of the rotating rod 403 rotate synchronously. When the multiple cleaning brushes 409 rub against the inner wall of the boiler, they will evenly smear the sprayed chemical agents, so that the chemical agents can fully contact and react with the scale on the inner wall of the boiler. Stop the rotation of the motor 402 and the extension of the electric telescopic rods 411. After waiting for the chemical agents to fully react with the scale, start the motor 402 again, so that the two second side frames 408 rotate rapidly in the boiler, and the multiple cleaning brushes 409 will continuously rub against the inner wall of the boiler to clean the loosened or dissolved scale, avoiding the easy harm to personnel when a person holds a spray kettle and reaches into the boiler to spray the agent, improving the safety of the boiler chemical cleaning device. When fixing, rubber pads are provided on the relative inner arc surfaces of the first fixing ring 201 and the second fixing ring 202. When the two fixing rings are tightly connected by bolts and closely fit on the boiler surface, the two rubber pads are squeezed, causing them to deform. The deformed rubber pads fill the space between the two fixing rings and the boiler body 1, increasing the frictional force between the two fixing rings and the boiler body 1 and improving the fixing effect of the boiler chemical cleaning device.

[0027] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
