[0035] S1. By placing the cleaning device M into the boiler, so that the cleaning part therein comes into contact with and abuts against the inner wall of the boiler;

[0036] The cleaning part of the cleaning device M can rotate, and a scraper is provided on the outside of the cleaning part. When the scraper rotates and comes into contact with the inner wall of the boiler, it can scrape off the ash and slag adhering to the inner wall of the boiler.

[0037] The cleaning device M is also equipped with a water spraying section. The water outlet of the water spraying section is located in front of the cleaning section. The water spraying softens the ash and slag to be cleaned, making the softened ash and slag easier to remove.

[0038] S2. By advancing the cleaning device M within the boiler, the cleaning section can be moved relative to the inner wall of the boiler to clean the ash and slag from the inner wall of the boiler;

[0039] The scraper is tilted in the cleaning section. When the scraper rotates to clean, it will drive the entire device forward, cleaning as it moves.

[0040] S3. The scraped ash residue is collected and processed uniformly through the collection section of the cleaning device M;

[0042] After the ash is crushed, it will collect with the sprayed water at the bottom of the cleaning section, and the water flow will carry the ash into the collection section.

[0043] Example 2

[0044] Reference Figure 1-4 In a second embodiment of the present invention, a boiler ash cleaning device is provided, the device comprising:

[0045] The cleaning unit 100 includes a drive box 101, a drive shaft 102 disposed in the drive box 101 and a drive motor and a battery, the drive shaft 102 being connected to the drive motor in the drive box 101, a cleaning component 103 disposed at the end of the drive shaft 102, and walking wheels 104 disposed on both sides of the drive box 101.

[0046] The water spray unit 200 includes a high-pressure water tank 201 disposed at the top of the drive box 101, a transfer component 202 disposed on the drive shaft 102 and connected to the high-pressure water tank 201, and a spray component 203 disposed between the transfer component 202 and the cleaning component 103.

[0047] The transfer assembly 202 includes a first transfer box 202a sleeved on the drive shaft 102, a connecting pipe 202b disposed between the first transfer box 202a and the high-pressure water tank 201, and a second transfer box 202c disposed at the end of the drive shaft 102 and rotatably sealed to the first transfer box 202a. The first transfer box 202a and the second transfer box 202c are rotatably connected and sealed between them by a rubber ring.

[0048] The second transfer box 202c is connected to the cleaning component 103. The spraying component 203 includes a plurality of support tubes 203a disposed on the second transfer box 202c, and a spraying head 203b disposed at the end of the support tubes 203a.

[0049] The cleaning assembly 103 includes a cleaning ring 103a mounted on a support pipe 203a, multiple slag-removing grooves 103b inclinedly mounted on the cleaning ring 103a, multiple arc-shaped scrapers 103c mounted on the sides of the multiple slag-removing grooves 103b, and a scraper ring 103d mounted on the outside of the cleaning ring 103a. The support pipe 203a passes through the cleaning ring 103a and connects to the spray head 203b. The spray head 203b is located in front of the arc-shaped scrapers 103c. Water from the high-pressure water tank 201 is passed through... The transfer component 202 is sprayed from the spray head 203b through the support pipe 203a to impact and soften the ash and slag in front of the arc-shaped scraper 103c. Then, the arc-shaped scraper 103c cleans the softened ash and slag. At the same time, the arc-shaped scraper 103c and the slag leakage trough 103b are both inclined. When the arc-shaped scraper 103c rotates, it can drive the entire device forward. The ash and slag scraped off by the arc-shaped scraper 103c and the scraper ring 103d enter the cleaning ring 103a from the slag leakage trough 103b.

[0050] The first transfer box 202a and the second transfer box 202c are equipped with a switch assembly 204 for opening and closing the connecting pipe 202b. The switch assembly 204 includes a transition box 204a sleeved on the drive shaft 102 and covering the outlet of the connecting pipe 202b. The transition box 204a is rotatably sealed with the first transfer box 202a. The transition box 204a has multiple through holes 204b and also includes a connecting spring 204c disposed on the second transfer box 202c. A sealing plate 204d is installed at the bottom of the spring 204c. The sealing plate 204d rotates and seals with the drive shaft 102, and also rotates and seals with the outer extension ring of the transition box 204a. The sealing plate 204d is also provided with multiple through holes 204b. A connecting part 204e is installed between the sealing plate 204d and the transition box 204a to seal the through holes 204b of the sealing plate 204d. At the same time, a resistance part 204f is provided on the inner wall of the transition box 204a and the first transfer box 202a.

[0051] The connecting part 204e includes multiple mounting plates 204e-1 disposed on the bottom surface of the sealing plate 204d. The number of mounting plates 204e-1 and the number of through holes 204b on the sealing plate 204d are the same. An arc spring 204e-2 is mounted on the mounting plate 204e-1. A sealing block 204e-3 is mounted on the end of the arc spring 204e-2. The sealing block 204e-3 slides and overlaps with the through hole 204b on the sealing plate 204d. The sealing block is fixed to the transition box 204a. The resistance part 204f includes multiple extrusion blocks 204f-1 that are elastically inserted into the inner wall of the first transfer box 202a. The extrusion blocks 204f-1 are inserted into the first transfer box 202a and are connected by a spring. Multiple actuating blocks 204f-2 that cooperate with the extrusion blocks 204f-1 are disposed around the transition box 204a. The inclination angles on both sides of the end of the extrusion block 204f-1 are inconsistent.

[0052] When the drive shaft 102 rotates, causing the connecting spring 204c, the sealing plate 204d, and the transition plate to rotate, the actuating block 204f-2 comes into contact with the squeezing block 204f-1. At this time, the pressure on the actuating block 204f-2 from the squeezing block 204f-1 is greater than the elastic force of the arc spring 204e-2, and the arc spring 204e-2 is compressed, opening the through hole 204b on the sealing plate 204d. Water in the high-pressure water tank 201 enters the transition box 204a through the connecting pipe 202b, enters the space between the sealing plate 204d and the transition box 204a through the through hole 204b on the transition box 204a, and then enters the interior of the first transfer box 202a and the second transfer box 202c through the through hole 204b on the sealing plate 204d. Finally, it is sprayed out from the spray head 203b through the support pipe 203a.

[0053] When the drive shaft 102 stops rotating, the elastic force of the arc spring 204e-2 is greater than that of the push transition box 204a, causing the trigger block 204f-2 to reverse. The trigger block 204f-2 abuts against the other side of the squeezing block 204f-1. At this time, the pressure of the squeezing block 204f-1 on the trigger block 204f-2 is less than that of the arc spring 204e-2. The sealing block returns to its position and coincides with the through hole 204b on the sealing plate 204d, thus closing the spray head 203b.

[0054] It also includes a collection unit 300, comprising a collection box 301 disposed at the bottom of the drive box 101 and rotating against the cleaning component 103. The bottom of the collection box 301 is arc-shaped and has the same arc as the bottom of the cleaning ring 103a. The inner wall of the cleaning ring 103a is inclined, and the ash and slag falling into the cleaning ring 103a slides along the inner wall and falls into the collection box 301. The bottom of the collection box 301 is made of mesh to allow the moisture in the ash and slag to flow out. It also includes a crushing component 302 disposed between the collection box 301 and the transfer component 202. The crushing component 302 can be made of a reciprocating hammer. The crushing component 302 crushes the ash and slag, reducing the space occupied by the ash and slag.

[0055] The remaining structure is the same as that in Example 1.

[0056] During use, the cleaning component 103 is placed in the boiler, and the drive shaft 102 is rotated by the drive box 101. When the drive shaft 102 rotates, the switch component 204 is turned on, and the water in the high-pressure water tank 201 enters the transfer component 202 and is sprayed out from the spray head 203b through the support pipe 203a. At the same time, the support pipe 203a rotates with the second transfer box 202c and the drive shaft 102, driving the spray head 203b and the cleaning ring 103a to rotate together, so as to thoroughly wash the inner wall of the boiler. At the same time, the cleaning ring 103a rotates, which can clean the inner wall of the boiler and drive the entire equipment forward. While moving forward, it cleans. The cleaned water falls into the cleaning ring 103a and is collected in the collection box 301.

[0057] Example 3

[0058] Reference Figure 1-7 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the crushing component 302 includes a U-shaped mounting frame 302a disposed at the top of the collection box 301, a crushing part 302b slidably disposed on the mounting frame 302a and located inside the collection box 301, a first elastic member 302c disposed between the mounting frame 302a and the crushing part 302b, the first elastic member 302c may be made of a spring or a metal sheet, and a driving part 302d disposed between the mounting frame 302a and the second transfer box 202c for driving the crushing part 302b.

[0059] The drive unit 302d includes a mounting cylinder 302d-1 disposed at the top of the mounting frame 302a, a telescopic rod 302d-2 slidably disposed at the bottom of the mounting cylinder 302d-1 and passing through the mounting frame 302a and abutting against the rolling part 302b, multiple air injection pipes 302d-3 disposed at the top of the mounting cylinder 302d-1, extrusion parts 302d-4 disposed on the air injection pipes 302d-3, and connecting pressure plates disposed on the multiple extrusion parts 302d-4. 302d-5, the movable block 302d-6 disposed on the connecting pressure plate 302d-5, and the corrugated slope 302d-7 disposed on the outside of the second transfer box 202c and slidingly engaged with the movable block 302d-6, can amplify the height difference of the movable block 302d-6 moving along the corrugated slope 302d-7 when the telescopic rod 302d-2 is extended through multiple air injection pipes 302d-3, thereby controlling the range of motion of the compaction section 302b.

[0060] The crushing section 302b includes a sliding column 302b-1 disposed at the bottom end of the first elastic member 302c and abutting against the bottom end of the telescopic rod 302d-2, and an arc-shaped pressure plate 302b-2 disposed at the lower end of the sliding column 302b-1. When the ash slag that has been scraped off falls to the bottom end of the cleaning ring 103a, it slides into the collection box 301. Since the ash slag that has been scraped off is in the form of flakes, multiple slags piled up together can easily take up space. The extension of the telescopic rod 302d-2 squeezes the arc-shaped pressure plate 302b-2, and at the same time stretches the first elastic member 302c. The arc-shaped pressure plate 302b-2 cooperates with the collection box 301 to squeeze and crush the ash slag, which can save space.

[0061] The movable block 302d-6 rotates relative to the wave slope 302d-7 and swings up and down. In cooperation with the first elastic element 302c, the arc-shaped pressure plate 302b-2 moves up and down as the movable block 302d-6 slides relative to the wave slope 302d-7, thus squeezing and crushing the ash.

[0062] The arc-shaped pressure plate 302b-2 is provided with multiple arc-shaped mounting tubes 302b-3 and curved claws 302b-4 elastically set in the arc-shaped mounting tubes 302b-3. The curved claws 302b-4 are inserted into the mounting tubes 302b-3 and the two are connected by a spring. The bending direction of the curved claws 302b-4 is the same as that of the cleaning component 103. When the arc-shaped pressure plate 302b-2 crushes the ash and slag, the curved claws 302b-4 are squeezed and compressed in the mounting tubes 302b-3. When the arc-shaped pressure plate 302b-2 is raised, the curved claws 302b-4 extend and grab and disperse the ash and slag being pressed, so that it can flow into the collection box 301 with the water flow.

[0063] The remaining structure is the same as that in Example 2.

[0064] During use, the cleaning component 103 is placed in the boiler, and the drive shaft 102 is rotated by the drive box 101. When the drive shaft 102 rotates, the switch component 204 is opened, and the water in the high-pressure water tank 201 enters the transfer component 202 and is sprayed out from the spray head 203b through the support pipe 203a. At the same time, the support pipe 203a rotates with the second transfer box 202c and the drive shaft 102, driving the spray head 203b and the cleaning ring 103a to rotate together, so as to wash the inner wall of the boiler in all directions. At the same time, the cleaning ring 103a rotates, which can clean the inner wall of the boiler and drive the entire equipment forward. While moving forward, it cleans. The ash and slag after cleaning fall into the cleaning ring 103a and fall into the collection box 301 where the arc-shaped pressure plate 302b-2 crushes and crushes it. Finally, it flows into the collection box 301 with the water flow and is collected.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
