[0032] In the specific implementation process, before slag removal, the diameter size of the outer circle formed by the three slag removing knives 10 can be adjusted according to the size of the inner wall of the boiler, at this time, the threaded rod 16 is rotated, the threaded rod 16 drives the first rack 17 to move, the first rack 17 drives the two gears 14 to rotate when moving, the two gears 14 respectively drive the two second racks 18 to move, so as to adjust the positions of the three connecting plates 19, adjust the diameter size of the outer circle formed by the three connecting plates 19, and further adjust the diameter size of the outer circle formed by the three slag removing knives 10, so that the slag removing knives 10 are closely attached to the inner wall of the boiler, so that the positions of the slag removing knives 10 can be adjusted according to the size of the inner wall of different boilers, and the versatility of the equipment is improved.

[0033] Embodiment 3: Please refer to Figure 1 and Figure 2 , the application provides a technical scheme: the bottom four corners of the bottom plate 1 are all installed with moving wheels 26, the top left side outer surface of the bottom plate 1 is fixedly connected with a push hand 27, the top outer surface of the bottom plate 1 away from the push hand 27 is fixedly connected with an L-shaped frame 21, the top downward outer surface of the L-shaped frame 21 is fixedly installed with a second electric push rod 22, the output end of the second electric push rod 22 is fixedly connected with a fixing frame 23, the outer surface of the fixing frame 23 is installed with a motor 24, the top outer surface of the connecting disc 2 is fixedly connected with a rotating disc 25, the top outer surface of the rotating disc 25 is fixedly connected with a rotating shaft, the output end of the motor 24 is fixedly connected with the rotating shaft, specifically, the push hand 27 is pushed, so that the moving wheels 26 move on the ground, which is convenient for moving the device, so that the three slag removing knives 10 are respectively corresponding to the positions of the inner wall of the boiler, the second electric push rod 22 is started, so that the second electric push rod 22 drives the connecting disc 2 to move downward, so that the connecting disc 2 is located at the furnace mouth of the boiler, at this time, the slag removing knives 10 extend into the inner wall of the boiler, the rotating disc 25 is driven to rotate by the motor 24, and the slag removing knives 10 perform the slag removing work on the inner wall of the boiler.

[0034] It is worth mentioning that the electric power driven wheel moving mode can be used instead of the push hand 27 to push the moving wheels 26 to move.

[0035] In this embodiment, the bottom outer surface of the three connecting plates 19 is all installed with a first electric push rod 20, the output end of the three first electric push rods 20 is respectively fixedly connected with the outer surface of the three mounting seats 3, specifically, the first electric push rod 20 drives the slag removing knives 10 to move, so that the slag removing knives 10 can clean the inner wall of the boiler with different depths.

[0036] In this embodiment, the top outer surface of the bottom plate 1 is fixedly connected with a counterweight box 29 away from one side of the L-shaped frame 21. Specifically, the counterweight box 29 counterweights the bottom plate 1, so that the center of gravity of the bottom plate 1 is located at the center, avoiding uneven stress on the bottom plate 1 and causing rollover.

[0037] In the specific implementation process, before slag removal, the pusher 27 is first pushed, so that the moving wheel 26 moves on the ground, facilitating the movement of the device, so that the three slag removal knives 10 are respectively located at positions corresponding to the inner wall of the boiler. The second electric push rod 22 is turned on, so that the second electric push rod 22 drives the connecting disc 2 to move downward, so that the connecting disc 2 is located at the furnace opening of the boiler. At this time, the slag removal knife 10 extends into the inner wall of the boiler. The rotating disc 25 is driven to rotate by the motor 24 to drive the slag removal knife 10 to remove slag on the inner wall of the boiler, and the first electric push rod 20 drives the slag removal knife 10 to move, so that the slag removal knife 10 can clean the inner wall of the boiler at different depths.

[0038] Working principle: when it is necessary to replace the slag removal knife 10, the side L-shaped lifting rod 12 is lifted upward, so that the side L-shaped lifting rod 12 slides in the sliding groove 13, the side L-shaped lifting rod 12 drives the conical cylinder 5 to move upward, the conical cylinder 5 drives the steel ball 7 to move upward, the spring 11 is deformed, the diameter of the conical shell 4 above is increased, so that the steel ball 7 moves outward, the gap between the plurality of steel balls 7 is increased, so that the pin 8 is released from the limiting, and the slag removal knife 10 can be easily removed. When installing a new slag removal knife 10, the pin 8 is directly inserted into the conical cylinder 5. When the needle of the pin 8 contacts the steel ball 7, the needle will drive the steel ball 7 to move upward and drive the conical cylinder 5 to move upward. Due to the conical structure of the conical shell 4, the three steel balls 7 will move outward, the gap between the three steel balls 7 will be increased, and the pin 8 will be easily inserted. When you want to pull out the pin 8, the pin 8 drives the steel ball 7 and the conical cylinder 5 to move downward. The steel ball 7 will be subjected to the inward force of the conical shell 4. The greater the force below the slag removal knife 10, the greater the engagement force of the steel ball 7 on the pin 8, which completely locks the pin 8 and makes it impossible to pull out, so that the slag removal knife 10 can be stably installed. Therefore, when installing the slag removal knife 10, only the side L-shaped lifting rod 12 needs to be forced and the pin 8 needs to be inserted, so that the slag removal knife 10 can be quickly replaced, and the installation of the slag removal knife 10 is more stable.

[0039] Before slagging, according to the size of the inner wall of the boiler, the diameter of the outer ring formed by the three slagging knives 10 can be adjusted, at this time, rotating the threaded rod 16, the threaded rod 16 drives the first rack 17 to move, the first rack 17 drives the two gears 14 to rotate when moving, the two gears 14 drive the two second racks 18 to move respectively, thereby adjusting the position of the three connecting plates 19, adjusting the diameter of the outer ring formed by the three connecting plates 19, and further adjusting the diameter of the outer ring formed by the three slagging knives 10, so that the slagging knife 10 closely fits the inner wall of the boiler, thereby the position of the slagging knife 10 can be adjusted according to the size of the inner wall of different boilers, improving the versatility of the equipment.

[0040] Before slagging, first push the push 27, so that the moving wheel 26 moves on the ground, facilitating the movement of the device, so that the three slagging knives 10 are respectively corresponding to the position of the inner wall of the boiler, turn on the second electric push rod 22, so that the second electric push rod 22 drives the connecting disc 2 to move down, so that the connecting disc 2 is located at the furnace opening of the boiler, at this time, the slagging knife 10 extends into the inner wall of the boiler, the rotating disc 25 is driven to rotate by the motor 24 to drive the slagging knife 10 to perform slagging work on the inner wall of the boiler, and the slagging knife 10 is driven to move by the first electric push rod 20, so that the slagging knife 10 can clean the inner wall of the boiler of different depths.
