Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 A boiler cleaning device includes a boiler 1 and a cleaning mechanism 2. The cleaning mechanism 2 is arranged on one side of the boiler 1. The cleaning mechanism 2 includes a mixer 204 and a first filter 214.

[0025] The front of the boiler 1 is connected to a delivery pipe 201, a valve 202 is arranged above the delivery pipe 201, and a pH sensor 203 is arranged inside the delivery pipe 201 near the end of the boiler 1. The pH sensor 203 is used to monitor the concentration parameters of the chemical solution. The sensor data can be transmitted to the controller 218 so as to adjust the concentration and proportion of the cleaning agent in real time.

[0026] The mixer 204 is arranged on one side of the valve 202. A stirring motor 205 is installed on the inner bottom surface of the mixer 204. A rotating shaft 206 is arranged inside the stirring motor 205. A stirring blade 207 is arranged on the outer surface of the rotating shaft 206. The mixer 204 is used to mix different cleaning agents in proportion. A stirring device is designed inside the mixer 204 to ensure that the solution is fully mixed and uniform.

[0027] A solution storage tank 208 is provided on the upper surface of the mixer 204, a sealing cover 209 is threadedly connected to the upper surface of the solution storage tank 208, and a solenoid valve 210 is installed on the lower surface of the solution storage tank 208. The solenoid valve 210 is used to adjust the flow rate and mixing ratio of the chemical solution to ensure the cleaning effect of the device.

[0028] One end of the water outlet of the boiler 1 is connected to a water outlet pipe 211, and the water outlet pipe 211 is used to discharge the clean water in time.

[0029] A sedimentation tank 212 is arranged below the outlet pipe 211, and a clean water tank 213 is arranged on one side of the sedimentation tank 212. The sedimentation tank 212 precipitates impurities in the clean water to ensure the quality of the clean water and prevent the device from being blocked by impurities and affecting the working efficiency. At the same time, adding a chemical solution for neutralizing the pH value into the sedimentation tank 212 can precipitate the scale dissolved in the clean water, avoiding the waste of water resources due to the replacement of clean water.

[0030] A second filter screen 215 is provided between the sedimentation tank 212 and the clean water tank 213. The second filter screen 215 performs secondary filtration on the clean water after sedimentation and treatment, thereby ensuring the cleanliness of the clean water and improving the circulation capacity of the device.

[0031] The first filter screen 214 is connected to the top slot of the sedimentation tank 212. A collecting tank 216 is provided on one side of the first filter screen 214. The first filter screen 214 is inclined toward the collecting tank 216. The inclined first filter screen 214 can filter impurities in the cleaning water. At the same time, impurities on the surface of the first filter screen 214 are flushed toward the collecting tank 216 by the cleaning water, so that the device has a certain self-cleaning ability.

[0032] A water pump 217 is provided on the bottom surface of the clean water tank 213 , and the water pump 217 is connected to the slot of the delivery pipe 201 . The water pump 217 pumps the filtered clean water back into the delivery pipe 201 to recycle the water resources.

[0033] A controller 218 is provided on one side of the sedimentation tank 212. The controller 218 is electrically connected to the solenoid valve 210. The controller 218 can control the solenoid valve 210 to inject chemical solution into the device, thereby avoiding the trouble of wasting manpower due to manual operation.

[0034] Working principle: The device is powered by an external power supply. First, the delivery pipe 201 and the water outlet pipe 211 are connected to the water inlet and the water outlet of the boiler 1, and clean water is injected into the clean water tank 213. The sealing cover 209 is opened to add a chemical solution into the solution storage tank 208. The pH value of the cleaning solution is set by the controller 218. Then the device starts to operate, and the water pump 217 pumps clean water into the delivery pipe 201. The valve 202 is turned to adjust the water injection rate. The pH sensor 203 detects the pH value of the cleaning solution injected into the boiler 1 and transmits the information to the controller 218. The controller 218 controls the solenoid valve 210 to work according to the information transmitted by the pH sensor 203. The solenoid valve 210 works to inject the chemical solution in the solution storage tank 208 into the mixer 204. The stirring motor 205 works to drive the rotating shaft 206 to rotate, and the rotating shaft 206 rotates with The dynamic stirring blade 207 rotates to stir and mix the chemical solution and the clean water. The clean water enters the boiler 1 to dissolve or flush out the impurities in the boiler. After that, the clean water is discharged from the outlet pipe 211 and flows to the first filter screen 214. The first filter screen 214 filters the impurities in the clean water. The filtered impurities are flushed by the clean water and move to the collecting tank 216. The collecting tank 216 collects and discharges the impurities. The clean water is filtered by the first filter screen 214 and then enters the sedimentation tank 212 for sedimentation. At the same time, a chemical solution can be added to the sedimentation tank 212 to precipitate the scale dissolved in the solution, so as to facilitate the reuse of the clean water. The clean water after sedimentation is filtered by the second filter screen 215 and then enters the clean water tank 213. Finally, the clean water is pumped back into the delivery pipe 201 by the water pump 217 to continue cleaning the boiler. In this way, a method for using a boiler cleaning device is completed.
