[0023] As shown in Figures 1 to 11 The boiler cleaning device of the present application comprises: a rack 1; a fixing mechanism 2 for fixing the boiler; a cleaning mechanism for cleaning the boiler.

[0024] The fixing mechanism 2 comprises: a cylinder 3 fixedly installed on the rack 1; a clamping plate 4 fixedly installed on the movable end of the cylinder 3; the clamping plate 4 is arranged in a V shape.

[0025] The fixing mechanism 2 is provided with two groups, which are symmetrically arranged on the rack 1.

[0026] When the boiler is fixed, the boiler is placed between the two clamping plates 4, and at this time the two cylinders 3 are started to drive the two clamping plates 4 to approach each other, so that the boiler can be clamped and fixed, preventing displacement of the boiler during cleaning.

[0027] Since the clamping plate 4 is arranged in a V shape, it is convenient to clamp and fix boilers of different diameters, improving the adaptability of the device.

[0028] The cleaning mechanism comprises: a mounting box 10; a linkage pipe one 27 and a linkage pipe two 28 penetratingly installed on the mounting box 10; a mounting shell 5 fixedly installed on the end of the linkage pipe one 27; a scraper 7 slidingly installed in the mounting shell 5; a linkage spring 6 fixedly installed between the scraper 7 and the mounting shell 5; a mounting frame 8 fixedly installed on the end of the linkage pipe two 28; a roller 9 rotatably installed on the mounting frame 8; a driving assembly driving the roller 9 to rotate; an adjusting assembly adjusting the position of the scraper 7 and the roller 9; a rotating assembly rotating the roller 9 and the scraper 7 along the axis of the mounting box 10; a lifting assembly lifting the roller 9 and the scraper 7; a liquid supply assembly supplying a descaling agent to the roller 9.

[0029] When the boiler is fixed, the lifting assembly is started to move the roller 9 and the scraper 7 into the boiler, and the roller 9 and the scraper 7 can be moved up and down in the boiler along the axial direction of the boiler, at this time, the position of the roller 9 and the scraper 7 is adjusted by the adjusting assembly, the roller 9 is first abutted with the inner wall of the boiler, and the driving assembly, the rotating assembly and the liquid supply assembly are started to rotate the roller 9, so that the roller 9 rotates around the axis of the mounting box 10, thereby uniformly applying the descaling agent on the inner wall of the boiler, so that the descaling agent reacts with the scale, thereby facilitating the removal of the scale.

[0030] When the descaling agent is applied, the driving assembly and the liquid supply assembly stop running, at this time, the adjusting assembly is started to move the scraper 7 to abut with the inner wall of the boiler, at this time, the scraper 7 rotates around the axis of the mounting box 10 under the driving of the rotating assembly, thereby scraping the scale on the inner wall of the boiler, thereby realizing the automatic cleaning of the scale in the boiler.

[0031] Through the elastic force of the connecting spring 6, the abutting force of the scraper 7 on the boiler is avoided to be too large, and the inner wall of the boiler is damaged.

[0032] In the present application, the cleaning mechanism is provided, which can realize the automatic cleaning of the scale in the boiler, improve the cleaning efficiency of the scale on the inner wall of the boiler, and can clean the boilers with different diameters, thereby improving the adaptability of the device.

[0042] When the roller 9 finishes coating the inner wall of the boiler, the power source 22 is started to reversely rotate, so that the two rollers 9 move close to each other, the two scrapers 7 move away from each other, and abut against the inner wall of the boiler.

[0043] In the present application, by adjusting the setting of the assembly, the position of the roller 9 and the scraper 7 can be adjusted, on the one hand, the descaling agent is first applied to the inner wall of the boiler, and the scale is scraped off, improving the cleaning effect of the scale, on the other hand, the position of the roller 9 and the scraper 7 can be adjusted according to the different diameters of the boiler, improving the adaptability of the device.

[0046] Specifically, after the position of the roller 9 or the scraper 7 is adjusted, the power source three 32 is started to drive the connecting pipe 31 to rotate, the connecting pipe 31 drives the mounting box 10 to rotate, thereby driving the roller 9 and the scraper 7, so that the roller 9 or the scraper 7 is in full contact with the inner wall of the boiler in the horizontal direction.

[0054] The liquid inlet pipe 45, the liquid outlet pipe 46 and the liquid return pipe 50 are all provided with electromagnetic valves.

[0055] When the piston 44 moves upward, the electromagnetic valve on the liquid inlet pipe 45 is opened, and the electromagnetic valves on the liquid outlet pipe 46 and the liquid return pipe 50 are both closed, at this time, the descaling agent enters the fixed pipe 40 through the liquid inlet pipe 45, when the piston 44 moves downward, the electromagnetic valve on the liquid outlet pipe 46 is opened, and the electromagnetic valves on the liquid inlet pipe 45 and the liquid return pipe 50 are both closed, at this time, the descaling agent passes through the liquid outlet pipe 46, the annular pipe one 51, the connecting pipe 31 and the liquid storage cavity 48 in sequence, and is sprayed on the surface of the drum 9 through the liquid spraying hole 49, through the rolling of the drum 9, the descaling agent can be evenly applied on the inner wall of the boiler, avoiding that the descaling agent is directly sprayed on the inner wall of the boiler, the descaling agent is easy to splash and cause waste, and the contact between the descaling agent and the scale is not uniform, affecting the cleaning effect of the scale.

[0056] When the coating of the descaling agent is completed, and the descaling agent is no longer sprayed on the roller 9, the electromagnetic valve on the liquid inlet pipe 45 is opened when the piston 44 moves upward, and the electromagnetic valves on the liquid outlet pipe 46 and the liquid return pipe 50 are both closed, and the electromagnetic valve on the liquid return pipe 50 is opened when the piston 44 moves downward, and the electromagnetic valves on the liquid inlet pipe 45 and the liquid outlet pipe 46 are both closed, so that the descaling agent flows back into the liquid storage tank 39, and at this time, the circulation of the descaling agent plays a mixing role, so that the components of the descaling agent are evenly distributed, and the deposition of the descaling agent is avoided, which affects the descaling effect.
