[0032] An upper flue 1, a mounting frame 2 is fixedly sleeved on the outer side of the upper flue 1, and a slot 3 extending to the inside of the mounting frame 2 is opened on the left side of the mounting frame 2;

[0033] The mounting mechanism is arranged on the left side of the mounting frame 2;

[0034] A soot blowing mechanism, which is arranged inside the slot 3;

[0035] Wherein, the mounting mechanism includes a baffle 15;

[0036] A transverse groove 10 is provided at both ends of the left side of the mounting frame 2, a transverse bar 11 is fixedly installed inside the transverse groove 10, a slider 12 is movably sleeved on the outer side of the transverse bar 11, a slot 14 is provided on the outer side of the slider 12, a baffle 15 is fixedly connected between the inner sides of the slider 12, the baffle 15 corresponds to the slot 3, a return spring 13 is elastically installed between the inner side of the transverse groove 10 and the left side of the slider 12, and the return spring 13 is movably connected to the outer side of the transverse bar 11.

[0037] When the sootblowing box 4 is taken out, the baffle 15 is pulled, so that the baffle 15 drives the slider 12 to move to the right, and the slider 12 moves to the right inside the transverse groove 10, stretching the return spring 13 to deform the return spring 13. When the slider 12 contacts the conical block 20, the slider 12 is fixed, and the baffle 15 is fixed to the outside of the slot 3, thereby shielding the slot 3. When the slot 3 needs to be installed, the push block 23 is pushed to make the baffle 15 rebound to its original position, so that the sootblowing box 4 is inserted into the slot 3.

[0038] By pulling the baffle 15, the baffle 15 drives the slider 12 to move to the right, and the slider 12 moves to the right to stretch the return spring 13, pulling the baffle 15 to the outside of the slot 3, thereby shielding the slot 3, and pushing the push block 23 to make the baffle 15 rebound so that the sootblowing box 4 can be installed inside the slot 3. Compared with the traditional slot upper flue sootblowing device, this slot upper flue sootblowing device shields the slot 3 through the baffle 15. When sootblowing work is required, the baffle 15 rebounds and the sootblowing box 4 can be installed inside the slot 3, which facilitates the sootblowing work.

[0039] Wherein, the soot blowing mechanism includes a soot blowing box 4;

[0040] The sootblowing box 4 is movably connected to the inside of the slot 3, and sootblowing ports 8 are evenly opened on the surface of the sootblowing box 4. Brush plates 9 are fixedly installed on both sides of the sootblowing box 4, and the brush plates 9 correspond to the inner wall of the upper flue 1. A sootblowing pipe 5 is fixedly installed on the left side of the sootblowing box 4, and a tee 6 is movably sleeved on the left end of the sootblowing pipe 5, and a main pipeline 7 is movably sleeved inside the tee 6.

[0041] A tee 6 is connected to the main pipe 7, which is connected to the soot blowing pipe 5 through the tee 6. When it is necessary to clean the accumulated dust inside the upper flue 1, the gas inside the main pipe 7 passes through the tee 6, the soot blowing pipe 5 and the soot blowing box 4, and then blows dust to the interior of the upper flue 1 through the soot blowing port 8. At the same time, when the soot blowing box 4 is inserted, the brush plate 9 contacts the inner wall of the upper flue 1 to clean the inner wall of the upper flue 1.

[0042] By inserting the sootblowing box 4 into the interior of the upper flue 1, the brush plate 9 is in contact with the interior of the upper flue 1 to clean the inner wall of the upper flue 1, and the sootblowing pipe 5 and the main pipeline 7 are connected through the tee 6, so that the gas in the main pipeline 7 passes through the sootblowing port 8 to clean the interior of the upper flue 1. Compared with the traditional trough upper flue sootblowing device, this trough upper flue sootblowing device cleans the inner wall of the upper flue 1 through the brush plate 9, and cleans the accumulated dust inside the upper flue 1 through the sootblowing port 8, which facilitates the sootblowing work.

[0043] A circular groove 16 is formed inside the mounting frame 2 , and a round block 18 is movably installed inside the circular groove 16 .

[0044] By installing the round block 18 inside the circular groove 16 , the round block 18 is driven to move inside the circular groove 16 when the connecting shaft 19 moves, thereby limiting the position of the connecting shaft 19 .

[0045] A movable groove 17 is formed inside the mounting frame 2 , and a connecting shaft 19 extending into the movable groove 17 is fixedly mounted on the outer side of the circular groove 16 .

[0046] The connection shaft 19 moves in the movable groove 17 to drive the round block 18 to move in the circular groove 16 , so that the round block 18 limits the connection shaft 19 .

[0047] A conical clamping block 20 is fixedly mounted on the outer side of the transverse groove 10 , and the conical clamping block 20 corresponds to the clamping groove 14 .

[0048] The slider 12 contacts the conical block 20 to push the conical block 20 to retract into the movable slot 17 . When the slot 14 is located in front of the conical block 20 , the conical block 20 rebounds and is inserted into the slot 14 to fix the slider 12 .

[0049] A telescopic spring 21 is elastically installed between the inner side of the conical clamping block 20 and the inner side of the movable groove 17 , and the telescopic spring 21 is movably connected to the outer side of the connecting shaft 19 .

[0050] The conical block 20 contracts to the inside of the movable slot 17 to squeeze the telescopic spring 21 . When the conical block 20 is located outside the slot 14 , the telescopic spring 21 pushes the conical block 20 to rebound and be inserted into the inside of the slot 14 .

[0051] A connecting block 22 is installed on the outer side of the conical clamping block 20 , a pushing block 23 is fixedly installed on the outer side of the connecting block 22 , an adjusting groove 24 is opened on the surface of the mounting frame 2 , and the connecting block 22 is movably connected inside the adjusting groove 24 .

[0052] The push block 23 is pushed so that the push block 23 drives the connecting block 22 to move inside the adjusting groove 24 , thereby adjusting the position of the conical clamping block 20 in the movable groove 17 .

[0053] The working principle and use process of this utility model:

[0054] When the sootblowing box 4 is taken out, the baffle 15 is pulled, so that the baffle 15 drives the slider 12 to move to the right, and the slider 12 moves to the right inside the transverse groove 10, stretching the return spring 13 to deform the return spring 13. When the slider 12 contacts the conical block 20, the slider 12 is fixed, and the baffle 15 is fixed to the outside of the slot 3, thereby shielding the slot 3. When the slot 3 needs to be installed, the push block 23 is pushed to make the baffle 15 rebound to its original position, so that the sootblowing box 4 is inserted into the slot 3.

[0055] A tee 6 is connected to the main pipe 7, which is connected to the soot blowing pipe 5 through the tee 6. When it is necessary to clean the accumulated dust inside the upper flue 1, the gas inside the main pipe 7 passes through the tee 6, the soot blowing pipe 5 and the soot blowing box 4, and then blows dust to the interior of the upper flue 1 through the soot blowing port 8. At the same time, when the soot blowing box 4 is inserted, the brush plate 9 contacts the inner wall of the upper flue 1 to clean the inner wall of the upper flue 1.
