Description

Technical Field

[0001] This utility model relates to the field of boiler flue gas outlet technology, specifically to an adjustable boiler flue gas outlet device. Background Technology

[0002] A boiler is an energy converter that uses the heat energy released by fuel combustion or other heat energy to heat fluids. It is often used in thermal power plants, ships, locomotives, and mines. During the combustion process, boilers produce a large amount of exhaust gas. This exhaust gas carries heat through heat utilization equipment and is then directly discharged into the atmosphere.

[0003] In the existing technology, the commonly used boiler flue gas outlets are all fixed round holes with fixed dimensions. When the boiler is running at low load, the back pressure is low and it cannot operate stably. If the round hole is reduced, the resistance of the flue gas outlet will be too high at high load, resulting in excessively high air pressure of the boiler fan and an increase in structural size, which is not conducive to compact layout. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application proposes an adjustable boiler flue gas outlet device, which can adjust the flue gas volume according to actual needs, increasing the practicality of the device and facilitating quick assembly and disassembly of the adjustment components by staff, reducing the workload of staff, and making it convenient for personnel to inspect, maintain, and clean the limit adjustment components.

[0005] This utility model provides the following technical solution: an adjustable boiler flue gas outlet device, comprising: a flue gas pipe, an installation seat sleeved on the outside of the flue gas pipe at the flue gas outlet, an overlap groove on one side of the installation seat, and a splicing adjustment mechanism installed on the installation seat and the overlap groove. The splicing adjustment mechanism includes a locking component, a torsion component, a guide frame, and a limit adjustment component. The guide frame and the overlap groove are slidably connected. The locking component is used to lock the position of the guide frame, the torsion component is used to unlock the guide frame, and the limit adjustment component is used to control the flue gas volume.

A connecting rod is rotatably connected to the inside of the installation groove. An extrusion block is sleeved on the outside of the connecting rod. The extrusion block and the docking block each have a first inclined slope that fits against each other at opposite ends. A pulling groove is provided on one side of the extrusion block near the bottom end. A first spring is installed between the inner side of the pulling groove and the inner wall of the installation groove.

[0008] As a preferred embodiment of this utility model, a rotating groove is formed inside the extrusion block at its first slope, a rotating rod is rotatably connected to the inside of the rotating groove, a rotating block is sleeved on the outside of the rotating rod, a torsion spring is installed between the rotating rod and the inner wall of the rotating groove, a second slope is formed on one side of the rotating block, the second slope fits into the first slope, and an abutment groove is formed inside the mating block at its first slope.

[0022] Example

[0023] like Figures 1 to 5 As shown, an adjustable boiler flue gas outlet device includes: a flue gas pipe 1, a mounting base 2 sleeved on the outside of the flue gas pipe 1 at the flue gas outlet, an overlap groove on one side of the mounting base 2, and a splicing adjustment mechanism installed on the mounting base 2 and the overlap groove. The splicing adjustment mechanism includes a locking component, a torsion component, a guide frame 3, and a limit adjustment component. The guide frame 3 is slidably connected to the overlap groove. The locking component is used to lock the position of the guide frame 3, the torsion component is used to unlock the guide frame 3, and the limit adjustment component is used to control the flue gas volume. The device has a simple structure and is easy to operate. The flue gas volume of the flue gas outlet can be adjusted according to actual needs, which increases the practicality of the device. It also facilitates the quick assembly and disassembly of the adjustment components by the staff, reducing the workload of the staff and facilitating the inspection, maintenance, and cleaning of the limit adjustment component.

[0024] In this embodiment, the limit adjustment assembly includes placement plates 13 installed at both ends of the inner wall of the guide frame 3. A fixing plate 14 is installed on one side between the two sets of placement plates 13. One side of the fixing plate 14 is attached to the exhaust port on the exhaust pipe 1. A sliding window 15 is slidably connected between the two sets of placement plates 13 on one side of the fixing plate 14. An exhaust groove 16 is provided inside the fixing plate 14 and the sliding window 15. Sliding grooves are provided on the opposite surfaces of the two sets of placement plates 13. Sliding blocks 17 are installed at both ends of the sliding window 15. The sliding blocks 17 and the sliding grooves are slidably connected. The cross-section of the sliding grooves and the sliding blocks 17 is T-shaped. A linear electric actuator is installed at one end of the guide frame 3. 18. The drive end of the linear electric actuator 18 extends to the inside of the guide frame 3 and is fixedly connected to one side of the sliding window 15. A sealing gasket is embedded on the side of the sliding window 15 near the fixed plate 14. First, starting the linear electric actuator 18 can drive the sliding window 15 to move. With the help of the sliding block 17 and the sliding groove, the stability of the sliding window 15 during movement can be ensured. According to actual needs, the smoke exhaust channels 16 on the sliding window 15 and the fixed plate 14 can be staggered or overlapped. The closer the two sets of smoke exhaust channels 16 are, the more gaps are exposed, increasing the smoke exhaust area. Conversely, the smoke exhaust area is reduced. The sealing gasket can increase the sealing of the contact between the fixed plate 14 and the sliding window 15 to prevent smoke from drifting out.

[0025] In this embodiment, a rotating groove is formed inside the extrusion block 7 at its first slope 8. A rotating rod is rotatably connected to the inside of the rotating groove. A rotating block 9 is sleeved on the outside of the rotating rod. A torsion spring 10 is installed between the rotating rod and the inner wall of the rotating groove. A second slope is formed on one side of the rotating block 9. The second slope fits into the first slope 8. An abutment groove is formed inside the docking block 4 at its first slope 8. Then, the guide frame 3 is inserted into the inner side of the overlap groove and the rubber pad 5 is retracted by continuing to press inward. The docking block 4 enters the inner side of the mounting groove through the docking groove. The two sets of first slopes 8 press against each other, forcing the extrusion block 7 to deflect and stretch the first spring 19. As the descent progresses, the first slope 8 contacts the second slope, causing the rotating block 9 to drive the torsion spring 10 to retract to the inner side of the rotating groove.

[0026] In this embodiment, the torsion assembly includes an operating groove on one side of the outer wall of the mounting base 2. A torsion plate 12 is installed at one end of the connecting rod 6 extending into the inner side of the operating groove. The connecting rod 6 is rotatably connected to the mounting base 2. A synchronization groove is provided on one side of the inner wall of the mounting groove. A synchronization block 11 that is slidably connected to the synchronization groove is installed at one end of the pressing block 7. Further, until the abutment groove is close to the rotating groove, the rotating block 9 pops out to the inner side of the rotating groove. At this time, the pressing rubber pad 5 rebounds a short distance, and the rotating block 9 abuts against the inner side of the abutment groove, thus completing the rapid locking of the guide frame 3.

[0027] In this embodiment, the locking component includes a rubber pad 5 installed on one side of the outer wall of the guide frame 3. A mating groove is provided inside the mounting base 2 on one side of the splicing groove. An extension hole corresponding to the mating groove is provided at one end of the rubber pad 5. A mating block 4 is installed on one side of the guide frame 3 at the extension hole. The mating block 4 is slidably connected to the mating groove. An installation groove is provided inside the mounting base 2 on one side of the mating groove. A connecting rod 6 is rotatably connected inside the installation groove. A pressing block 7 is sleeved on the outside of the connecting rod 6. A first mating part is provided at the opposite end of the pressing block 7 and the mating block 4. A traction groove is provided on one side of the slope 8 and the extrusion block 7 near the bottom. A first spring 19 is installed between the inner side of the traction groove and the inner wall of the installation groove. Furthermore, when it is necessary to remove the guide frame 3 to inspect and clean the limit adjustment component, the torsion plate 12 on the inner side of the operating groove can be pinched to drive the connecting rod 6 and the extrusion block 7 to rotate in conjunction with the synchronous block 11 and the synchronous groove, so that the rotating block 9 actively moves away from the inner side of the abutment groove. The rubber pad 5 fully rebounds, so that the abutment groove moves away from the rotating groove. At this time, the guide frame 3 and the limit adjustment component can be removed together for inspection, maintenance and cleaning.

[0028] Implementation Plan: Activating the linear electric actuator 18 moves the sliding window 15. The sliding block 17 and sliding groove ensure the stability of the sliding window 15 during movement. Depending on actual needs, the smoke exhaust channels 16 on the sliding window 15 and the fixed plate 14 can be staggered or overlapped. The closer the two sets of smoke exhaust channels 16 are, the more exposed the gaps, increasing the smoke exhaust area; conversely, the further apart they are, the smaller the smoke exhaust area. The sealing gasket increases the sealing at the joint between the fixed plate 14 and the sliding window 15, preventing smoke from escaping. The guide frame 3 is inserted into the overlapping groove, and further inward pressure causes the rubber gasket 5 to retract. The mating block 4 passes through the mating groove and enters the mounting groove. The two sets of first ramps 8 press against each other, forcing the pressing block 7 to deflect and stretch the first spring 19. As the descent increases, the first... When the first ramp 8 contacts the second ramp, the rotating block 9 drives the torsion spring 10 to retract to the inside of the rotating groove. After the abutment groove is close to the rotating groove, the rotating block 9 pops out to the inside of the rotating groove. At this time, the rubber pad 5 is no longer squeezed and rebounds a short distance. The rotating block 9 abuts against the inside of the abutment groove, completing the quick locking of the guide frame 3. When the guide frame 3 needs to be removed for inspection and cleaning of the limit adjustment component, the torsion plate 12 on the inside of the operating groove can be pinched in conjunction with the synchronous block 11 and the synchronous groove to drive the connecting rod 6 and the squeezing block 7 to rotate, so that the rotating block 9 actively moves away from the inside of the abutment groove. The rubber pad 5 fully rebounds, so that the abutment groove moves away from the rotating groove. At this time, the guide frame 3 and the limit adjustment component can be removed together for inspection, maintenance and cleaning.
