When the inner wall of the connecting pipe 2 is clogged, rotate the adjusting rod 51. Under the action of the adjusting rod 51, the cleaning brush 52 can be rotated, and then the cleaning brush 52 can clean the slag attached to the inner wall of the connecting pipe 2. Then, the internal through hole of the connecting pipe 2 is cleaned by a tool to prevent it from being blocked and affecting the normal use of the boiler. When it is necessary to disassemble and assemble the hood body 3, first make the screw mechanism 411 start working. Under the action of the screw mechanism 411, the connecting frame 412 can be driven to move, and then the clamping ring 42 can be driven to move through the connecting frame 412, so that the clamping ring 42 is separated from the outside of the connecting pipe 2. Then the staff can replace or disassemble the hood body 3 by pulling the connecting pipe 2 and the hood body 3.

[0023] The adjusting member 41 includes a screw mechanism 411 disposed on the outside of the air duct 1 for adjusting the position of the clamping ring 42, and a connecting frame 412 disposed on the outside of the screw mechanism 411 for maintaining the stable movement of the clamping ring 42. The screw mechanism 411 includes a fixing frame for fixing the screw, a screw and a rotating rod. When the screw mechanism 411 works normally, it can drive the connecting frame 412 to move, so that the connecting frame 412 can drive the clamping ring 42 to move, so that the clamping ring 42 can be separated from the outside of the connecting pipe 2, thereby facilitating the staff to pull the connecting pipe 2 and the hood body 3.

[0024] The clamping member 43 includes a clamping plate 431 disposed outside the clamping ring 42 for clamping the connecting pipe 2, and a positioning bolt 432 disposed inside the clamping plate 431 for fixing the clamping ring 42. Under the action of the positioning bolt 432, the positioning bolt 432 is rotated so that the positioning bolt 432 enters the clamping plate 431 and the clamping ring 42, so that the clamping plate 431 can be tightly connected with the clamping ring 42.

[0025] The snap ring 42 includes a first screw hole 6 provided therein for cooperating with the positioning bolt 432, and the clamping plate 431 includes a second screw hole 14 provided therein, and the inner wall of the second screw hole 14 is threadedly connected to the outer side of the positioning bolt 432. Under the action of the first screw hole 6 and the second screw hole 14, the positioning bolt 432 can enter the inside of the clamping plate 431 and the snap ring 42, so that the two snap rings 42 can be fixed to prevent the snap rings 42 from shifting at will.

[0026] The clamping ring 42 further includes a first connecting groove 7 formed inside.

[0027] like Figure 2 and Figure 3 The air duct 1 also includes a clamping groove 8 opened inside for positioning the connecting pipe 2, and the connecting pipe 2 includes a second connecting groove 9 opened inside.

Under the action of the sealing ring 10, the inner ring of the sealing ring 10 is tightly fitted with the inner wall of the second connecting groove 9, and the outer side of the sealing ring 10 is tightly fitted with the inner wall of the first connecting groove 7, so that the sealing ring 10 can seal the connection between the connecting pipe 2 and the clamping ring 42.

[0029] like Figure 3 and Figure 4As shown, the adjustment rod 51 includes a fixing tube 11 threadedly connected to the outside, and the top of the fixing tube 11 is fixedly connected to the top of the inner cavity of the hood body 3. When the adjustment rod 51 rotates, under the action of the fixing tube 11, the length of the adjustment rod 51 can be adjusted, and then the position of the adjustment rod 51 and the cleaning brush 52 can be adjusted.

[0030] The adjusting rod 51 includes a bottom tube 12 fixedly connected to the bottom, and a sleeve 13 fixedly connected to the outside of the bottom tube 12, and the outside of the sleeve 13 is fixedly connected to the inner wall of the cleaning brush 52. When the adjusting rod 51 rotates, the bottom tube 12 and the sleeve 13 can be driven to rotate, and then the sleeve 13 can drive the cleaning brush 52 to rotate, and the outside of the cleaning brush 52 is closely attached to the inner wall of the connecting pipe 2, so that the slag attached to the inner wall of the connecting pipe 2 can be cleaned.

[0031] Working principle: When the hood body 3 and the connecting pipe 2 are used for a long time, the through hole inside the connecting pipe 2 may be blocked. The adjusting rod 51 is rotated, and the adjusting rod 51 rotates inside the fixed pipe 11, so that the adjusting rod 51 can be adjusted in position. When the adjusting rod 51 rotates, the bottom pipe 12 and the sleeve 13 can be driven to rotate, and the rotation of the bottom pipe 12 and the sleeve 13 can drive the cleaning brush 52 to rotate inside the connecting pipe 2. The inner wall of the connecting pipe 2 fits tightly with the outer side of the cleaning brush 52, and the cleaning brush 52 can clean the slag attached to the inner wall of the connecting pipe 2. After the slag on the inner wall of the connecting pipe 2 is cleaned, The slag attached to the internal through hole of the connecting pipe 2 is cleaned by tools to prevent the connecting pipe 2 and the hood body 3 from being blocked and affecting the normal operation of the boiler. When the hood body 3 and the connecting pipe 2 are burned and need to be disassembled and replaced, the screw mechanism 411 is first started to work, and then the screw mechanism 411 can start to work through the connecting frame 412 when it is working, so that the clamping ring 42 is separated from the outside of the connecting pipe 2, and then the staff pulls the hood body 3 and the connecting pipe 2 so that the connecting pipe 2 can be separated from the inside of the slot 8, thereby facilitating the disassembly and assembly of the hood body 3 and the connecting pipe 2.
