[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] In this embodiment, as shown in FIG. Figure 1 and Figure 2As shown, the boiler smoke exhaust device includes a smoke exhaust pipe 6, a filter box 7 and a filter assembly. The inlet of the smoke exhaust pipe 6 is suitable for being connected to the smoke outlet of the boiler combustion chamber 4; the filter box 7 has a smoke inlet and a smoke outlet 8, and the smoke inlet and the smoke outlet 8 are arranged in sequence along the flow path of the smoke in the filter box 7. The smoke inlet of the filter box 7 is connected to the smoke outlet of the smoke exhaust pipe 6; the filter assembly includes a filter component 9 and a mounting component 10. The side wall of the filter box 7 is provided with a mounting hole. The filter component 9 is installed in the filter box 7 through the mounting hole. The filter component 9 is connected to the mounting component 10, and the mounting component 10 is detachably connected to the filter box 7.

[0026] Specifically, Figure 1 and Figure 2 As shown, the smoke inlet of the filter box 7 is arranged at the bottom of one end of the filter box 7, the smoke outlet 8 of the filter box 7 is arranged at the top of the other end of the filter box 7, and the filter component 9 is arranged in the middle of the filter box 7. The smoke enters the filter box 7 through the smoke inlet of the filter box 7, and then is filtered by the filter component 9 and discharged from the smoke outlet 8 of the filter box 7.

[0027] It can be understood that smoke discharged from the smoke outlet of the boiler combustion chamber 4 is discharged through the smoke exhaust pipe 6, and smoke discharged from the smoke exhaust pipe 6 enters the interior of the filter box 7 through the smoke inlet of the filter box 7, and smoke is filtered by the filter component 9 and discharged from the smoke outlet of the filter box 7. The filter component 9 is connected to the mounting component 10 and installed in the filter box 7 through the mounting hole. The mounting component 10 is detachably connected to the filter box 7. After the mounting component 10 is removed from the filter box 7, the filter component 9 can be taken out of the filter box 7 through the mounting hole through the mounting component 10, so that the filter component 9 can be easily cleaned, the blockage of the filter component 9 is reduced, and the filter box 7 can be stably discharged.

[0028] In this embodiment, the filter component 9 includes a plurality of filter screens, and the plurality of filter screens are respectively connected to the mounting components 10 and are sequentially arranged at intervals along the flow path of the smoke in the filter box 7 .

[0029] Specifically, the filter box 7 is provided with mounting holes corresponding to each filter screen, so that each filter screen can be inserted into one mounting hole.

[0030] It is understandable that by sequentially arranging a plurality of filter screens along the flow path of the smoke in the filter box 7, the filtering effect on the smoke can be improved.

[0031] In this embodiment, if Figure 2 and Figure 3As shown, a fixing block 1006 is provided on the side wall of the filter box 7, and a fixing hole is provided on the fixing block 1006. The mounting component 10 includes a mounting frame 1001, a first driving member, a first transmission member 1005 and a locking member 1007. The mounting frame 1001 is located on one side of the filter box 7; the first driving member is provided on the mounting frame 1001; the input end of the first transmission member 1005 is connected to the first driving member; the locking member 1007 is connected to the output end of the first transmission member 1005, and the first driving member is used to drive the locking member 1007 to be inserted into the fixing hole or removed from the fixing hole through the first transmission member 1005 to fix the mounting frame 1001.

[0032] When the filter element 9 is fixed by the mounting member 10, the filter element 9 is inserted from the mounting hole into the interior of the filter box 7 by moving the mounting frame 1001, and then the first driving member drives the first transmission member 1005 to drive the locking member 1007 to be inserted into the fixing hole of the fixing block 1006, and the locking member 1007 is limited by the fixing block 1006, so that the mounting frame 1001 is fixed on the filter box 7. When the filter element 9 needs to be taken out of the filter box 7, the first driving member drives the first transmission member 1005 to move, and the first transmission member 1005 drives the locking member 1007 to move out of the fixing hole, so that the filter element 9 can be taken out of the filter box 7 by moving the mounting frame 1001.

[0033] In this embodiment, if Figure 2 and Figure 3 As shown, two fixing blocks 1006 are provided, and the two fixing blocks 1006 are spaced apart on the filter box 7 . Two locking members 1007 are provided, and the two locking members 1007 are connected to the first transmission member 1005 respectively, and the two locking members 1007 are connected to the two fixing blocks 1006 in a one-to-one correspondence.

[0034] It should be noted that the two locking members 1007 are respectively connected to the first transmission member 1005, and the first transmission member 1005 can drive the two locking members 1007 to move synchronously, that is, to be inserted into the corresponding fixing holes synchronously, or to be removed from the corresponding fixing holes synchronously. By setting two fixing blocks 1006 to limit the locking members 1007, the stability of the connection of the mounting frame 1001 can be improved.

[0035] In this embodiment, if Figure 3 As shown, the first transmission member 1005 includes a driving bevel gear, a screw 1004 and a driven bevel gear, the driving bevel gear is arranged on the output shaft of the first driving member; the screw 1004 is rotatably connected to the mounting frame 1001, and the locking member 1007 is threadedly connected to the outer peripheral surface of the screw 1004; the driven bevel gear is arranged on the outer peripheral surface of the screw 1004, and the driven bevel gear and the driving bevel gear are meshed with each other.

[0036] Specifically, the locking piece 1007 is cylindrical, and an inner wall of the locking piece 1007 is provided with an internal thread. The locking piece 1007 is threadedly connected to the outer peripheral surface of the screw rod 1004 . When the screw rod 1004 is rotated, the locking piece 1007 can move along the screw rod 1004 .

[0037] For example, the first driving member includes a rotating wheel and a rotating rod, the rotating wheel is rotatably connected to the mounting frame 1001 through the rotating rod, and the rotating wheel is manually rotated to drive the rotating rod to drive the active bevel gear to rotate. The mounting component 10 also includes a limiting member, the limiting member is arranged on the rotating wheel, and a limiting hole is arranged on the mounting frame 1001 corresponding to the limiting member, and the relative position of the limiting member and the limiting hole corresponds to the locking position of the locking member 1007, so that after the locking member 1007 is inserted into the fixing hole by driving the first transmission member 1005 through the rotating wheel, the limiting member is inserted into the limiting hole to prevent the locking member 1007 from being moved out of the fixing hole by accidentally touching the rotating wheel.

[0038] When two fixing blocks 1006 are provided, a first thread and a second thread are respectively provided at both ends of the screw 1004, and the rotation directions of the first thread and the second thread are opposite. A locking piece 1007 is respectively provided at both ends of the screw 1004. When the screw 1004 rotates, the moving directions of the two locking pieces 1007 are opposite, so that they can be synchronously removed from the fixing holes of the fixing blocks 1006 at both ends or synchronously inserted into the fixing holes of the fixing blocks 1006.

[0039] It can be understood that the first driving member drives the active bevel gear to rotate, the active bevel gear drives the driven bevel gear to rotate, the driven bevel gear drives the screw 1004 to rotate, and the rotation of the screw 1004 drives the locking member 1007 to move, so that the locking member 1007 can enter or move out of the fixing hole.

[0040] In this embodiment, if Figure 3 As shown, the outer wall of the locking member 1007 is provided with a guide block, and the mounting frame 1001 is provided with a slide groove extending along the axial direction of the screw rod 1004 corresponding to the guide block. The guide block is inserted in the slide groove and can move along the inner wall of the slide groove.

[0041] Specifically, guide blocks are provided on opposite sides of the outer wall of the locking member 1007, and a slide groove is provided on the mounting member corresponding to each guide block. Through the cooperation of the guide block and the slide groove, the locking member 1007 can be stably moved along the mounting frame 1001 through the guide block.

[0042] In this embodiment, a guide block is provided on the outer wall of the locking member 1007, and a slide groove extending along the axial direction of the screw 1004 is provided on the mounting frame 1001 corresponding to the guide block. When the screw 1004 drives the locking member 1007 to move, the guide block and the slide groove cooperate to stabilize the movement, thereby preventing the locking member 1007 from rotating around the screw 1004 and affecting the movement.

[0043] In this embodiment, if Figure 2 , Figure 4 and Figure 5 As shown, the boiler smoke exhaust device further includes a vibration component 11, which is disposed on one side of the filter box 7, and is used to drive the filter box 7 to vibrate.

[0044] It can be understood that by arranging a vibration component 11 on one side of the filter box 7 and utilizing the vibration component 11 to vibrate the filter box 7, when the filter box 7 vibrates, the filter screen component 9 can be driven to vibrate. When the filter screen component 9 vibrates, dust on the filter screen component 9 can be made to fall off, thereby reducing the clogging of the filter screen component 9.

[0045] In this embodiment, if Figure 4 and Figure 5 As shown, the vibration component 11 includes a guide member and a movable frame 1105, an impact member 1106, an elastic reset member 1107, a second driving member 1102, and a second transmission member. The guide member is arranged on the filter box 7, the guide member is arranged on the filter box 7, the movable frame 1105 is connected to the guide member and is movable relative to the guide member; the impact member 1106 is connected to the movable frame 1105; one end of the elastic reset member 1107 is connected to the filter box 7, and the other end of the elastic reset member 1107 is connected to the impact member 1106; the second driving member 1102 is arranged on one side of the filter box 7; the input end of the second transmission member is connected to the output end of the second driving member 1102; the second driving member 1102 drives the movable frame 1105 away from the filter box 7 through the second transmission member.

[0046] For example, the vibration assembly 11 further includes a mounting frame 1101, and the mounting frame 1101 is connected to the filter box 7. The guide member, the movable frame 1105, the impact member 1106 and the second transmission member can all be arranged in the space enclosed between the mounting frame 1101 and the outer wall of the filter box 7 to avoid external interference and reduce safety hazards.

[0047] The guide member may be rod-shaped, and a mounting hole is provided on the movable frame 1105 , and the movable frame 1105 is disposed on the outer peripheral surface of the guide member through the mounting hole.

[0048] For example, the impact member 1106 includes a support plate and an impact plate arranged in the circumferential direction of the support plate, the support plate is parallel to the side wall of the filter box 7, the impact plate support plate faces one side of the filter box 7, one end of the elastic reset member 1107 is connected to the outer wall of the filter box 7, and the other end is connected to the support plate. In addition, the elastic reset member 1107 can be a spring, and of course, the elastic reset member 1107 can also be set in other forms, which is not limited here.

[0049] When the filter box 7 needs to be vibrated, the second driving member 1102 drives the movable frame 1105 away from the filter box 7 through the second transmission member, and the movable frame 1105 drives the impact member 1106 away from the filter box 7, and the elastic reset member 1107 is stretched. When the movable frame 1105 moves to a preset distance, the elastic reset member 1107 drives the impact member 1106 to reset, and the impact member 1106 hits the filter box 7, thereby vibrating the filter box 7, and then the filter component vibrates to shake off the dust.

[0050] In this embodiment, if Figure 4 As shown, the second transmission member includes a rotating shaft 1103 and a cam 1104 . The rotating shaft 1103 is connected to the second driving member 1102 . The cam 1104 is arranged on the outer peripheral surface of the rotating shaft 1103 , and the side wall of the cam 1104 abuts against the moving frame 1105 .

[0051] For example, the second driving member 1102 may be a motor, the rotating shaft 1103 is connected to the output shaft of the motor, and the motor may drive the cam 1104 to rotate via the rotating shaft 1103 .

[0052] It can be understood that when the second driving member 1102 drives the cam 1104 to rotate through the rotating shaft 1103, during the pushing process, the cam 1104 drives the movable frame 1105 away from the filter box 7, and the elastic reset member 1107 is stretched. During the return process, the elastic reset member 1107 drives the movable frame 1105 to reset, thereby causing the impact member 1106 to impact the filter box 7.

[0053] In this embodiment, if Figure 1 and Figure 2 As shown, the boiler includes a boiler body 2 and the above-mentioned boiler smoke exhaust device. The boiler body 2 has a combustion chamber 4, and the inlet of the smoke exhaust pipe 6 is connected to the smoke outlet of the combustion chamber 4.

[0055] The boiler in this embodiment is provided with the boiler smoke exhaust device, and the smoke exhausted from the smoke outlet of the combustion chamber 4 is discharged through the smoke exhaust pipe 6, and the smoke exhausted from the smoke exhaust pipe 6 enters the interior of the filter box 7 through the smoke inlet of the filter box 7, and the smoke is filtered by the filter screen component 9 and discharged from the smoke outlet of the filter box 7. The filter screen component 9 is easy to disassemble, and the filter screen component 9 can be easily cleaned, reducing the blockage of the filter screen component 9, so that the filter box 7 can stably exhaust smoke.
