[0035] The top wall of combustion chamber 2 is provided with two clamping assemblies 9, and the two clamping assemblies 9 are symmetrically arranged left and right about the through -hole 4; the two clamping assemblies 9 are located outside the two support blocks 7 respectively; the clamping assembly 9 located on the right side comprises a base 10 welded to the top wall of the combustion chamber 2 and a threaded rod 11; a square rod 12 is fixedly arranged on the right end face of the base 10; a movable block 13 is slidably sleeved on the square rod 12; a square hole 20 is formed in the movable block 13; the movable block 13 is sleeved on the square rod 12 through the square hole 20; a bevel 14 is formed on the right side end of the movable block 13; a rectangular clamping block 15 is welded to the left end face of the movable block 13; the rectangular clamping block 15 is embedded in the rectangular slot 8 of the support block 7 located on the right side; a horizontal spring 16 in a compressed state is further sleeved on the square rod 12; the left end of the horizontal spring 16 is fixedly arranged on the right end face of the base 10; the right end of the horizontal spring 16 is fixedly arranged on the left end face of the movable block 13.

[0036] A nut 17 is threadedly connected to the threaded rod 11; a wedge-shaped block 18 is sleeved on the threaded rod 11; a through slot 21 is formed in the wedge-shaped block 18; the wedge-shaped block 18 is sleeved on the outer portion of the threaded rod 11 through the through slot 21; the wedge surface of the wedge-shaped block 18 cooperates with the bevel 14 of the movable block 13; a vertical spring 19 in a compressed state is further sleeved on the threaded rod 11; the top end of the vertical spring 19 is fixedly arranged on the bottom surface of the wedge-shaped block 18; the bottom end of the vertical spring 19 is fixedly arranged on the top wall of the combustion chamber 2.

[0037] The working principle of the utility model is as follows:

[0038] When the flue 1 is used for a period of time, a large amount of dust is attached to the inner wall of the flue 1; therefore, workers need to dismount the flue 1 from the combustion chamber 2 to clean the flue 1; the specific dismounting method is as follows:

[0039] S1, workers rotate the nuts 17 of the two clamping assemblies 9 upwards; the nuts 17 move upwards along the threaded rods 11; in the process of moving upwards, the vertical spring 19 in a compressed state is lifted upwards under the elastic restoring force, the wedge surface of the wedge-shaped block 18 gradually separates from the bevel 14 of the movable block 13; in the process of separating, the horizontal spring 16 in a compressed state drives the movable block 13 to move outward along the square rod 12 under the elastic restoring force; the movable block 13 drives the rectangular clamping block 15 to move rightward synchronously;

[0040] S2, when the nut 17 moves upward to a certain height, the two rectangular clamping blocks 15 of the two clamping assemblies 9 are respectively out of the rectangular grooves 8 of the support blocks 7, as shown, at this time, the worker can take away the smoke exhaust pipe 1 from the top wall of the combustion chamber 2, and when it is taken away, the smoke exhaust pipe 1 can be cleaned. Figures 12-13

[0041] Among them, from steps S1~S2, the worker only needs to rotate the nut 17 of the two clamping assemblies 9 upward, so that the rectangular clamping block 15 is out of the rectangular groove 8 of the support block 7, and then the worker can quickly disassemble the smoke exhaust pipe 1 from the combustion chamber 2. Therefore, compared with the mounting structure as shown in Figures 1-2 Without the worker unscrewing the plurality of screws 6 between the flange plate 3 and the top wall of the combustion chamber 2, the smoke exhaust pipe 1 can be disassembled, thereby greatly reducing the working intensity of the worker, and in addition, the time for disassembling the smoke exhaust pipe 1 is saved, thereby greatly improving the disassembly efficiency of the smoke exhaust pipe 1.

[0042] When the smoke exhaust pipe 1 is cleaned, the worker re-installs the smoke exhaust pipe 1 on the top wall of the combustion chamber 2 by the following method:

[0043] S3, the worker supports the two support blocks 7 of the smoke exhaust pipe 1 on the top wall of the combustion chamber 2, at the same time, ensures that the smoke exhaust pipe 1 is communicated with the through hole 4 of the combustion chamber 2, and at the same time, ensures that the rectangular grooves 8 of the two support blocks 7 are respectively opposite to the rectangular clamping blocks 15 of the two clamping assemblies 9;

[0044] S4, the worker rotates the nut 17 of the two clamping assemblies 9 downward, the nut 17 moves downward along the threaded rod 11, at the same time, the nut 17 pushes the wedge block 18 downward, the wedge block 18 compresses the vertical spring 19 downward, at the same time, the wedge block 18 pushes the movable block 13 to move inward along the square rod 12, the movable block 13 drives the rectangular clamping block 15 to move toward the rectangular groove 8 of the support block 7, when the nut 17 descends to a certain height, the rectangular clamping blocks 15 of the two clamping assemblies 9 are respectively embedded into the rectangular grooves 8 of the two support blocks 7, as shown, thereby fixing the two support blocks 7, and then fixing and installing the smoke exhaust pipe 1 on the top wall of the combustion chamber 2, thereby realizing the quick installation of the smoke exhaust pipe 1. Figures 3-4

[0045] Among them, from steps S3~S4, the worker only needs to rotate the nut 17 of the two clamping assemblies 9 downward, so that the wedge block 18 pushes the movable block 13 inward, and then the two rectangular clamping blocks 15 are respectively embedded into the rectangular grooves 8 of the two support blocks 7, thereby realizing the installation and fixation of the smoke exhaust pipe 1 on the top wall of the combustion chamber 2. Therefore, compared with the mounting structure as shown in Figures 1-2 ​​The mounting structure shown can install the exhaust pipe 1 on the top wall of the combustion chamber 2 without workers tightening a plurality of screws 6 between the flange 3 and the top wall of the combustion chamber 2, thereby greatly reducing the working strength of the workers, saving the time for installing the exhaust pipe 1, and greatly improving the installation efficiency of the exhaust pipe 1.

[0046] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement.
