Description

Technical Field

[0001] This application relates to the field of power generation equipment for civil defense works, and in particular to a smoke elimination and cooling device. Background Technology

[0002] Currently, civil defense fortifications are built in cities, and the power supply inside these fortifications is usually provided by diesel generators to ensure the power supply within them.

[0003] The exhaust gas from diesel generators contains a large amount of soot particles, which cause a lot of black smoke to be emitted from the generator's exhaust port. This black smoke is discharged through the ventilation system of the civil defense fortification, making the civil defense facilities easier for the enemy to detect during wartime and reducing their concealment. Summary of the Invention

[0004] In order to improve the problem that black smoke emitted by diesel generators is discharged through the ventilation system, which makes civil defense facilities easy to be detected by the enemy during wartime and reduces the concealment of civil defense fortifications, this application provides a smoke elimination and cooling device.

[0005] The smoke elimination and cooling device provided in this application adopts the following technical solution:

[0006] A smoke elimination and cooling device includes a bracket and at least two air guide pipes mounted on the bracket. Each air guide pipe is connected to the exhaust pipe of a diesel generator. Each air guide pipe contains a particulate filter, and both ends of the particulate filter are fitted with mounting rings. Each air guide pipe contains two fixing rings, and each fixing ring is connected to the air guide pipe by a support spring. The support spring is used to push the two fixing rings closer together. The particulate filter can be inserted between the two fixing rings, and the mounting ring can be inserted into the fixing ring and abut against the fixing ring.

[0007] By adopting the above technical solution, when the diesel generator generates electricity, the exhaust gas is transported to the air guide pipe through the exhaust pipe of the diesel generator. Since the mounting ring is inserted into the fixing collar and the support spring presses the fixing collar against the mounting ring, the exhaust gas is discharged after passing through the particulate filter. When the exhaust gas passes through the particulate filter, the solid particulate matter in the exhaust gas is adsorbed, thereby removing the black smoke in the exhaust gas, which can improve the concealment of civil defense works in wartime.

[0008] In one specific implementation, the exhaust pipe of the diesel generator is connected to multiple air guide pipes via an electromagnetic reversing valve. Each air guide pipe is equipped with two gas pressure sensors, which are located on both sides of the particulate filter. The electromagnetic reversing valve is equipped with a controller. The input terminal of the controller is electrically connected to the gas pressure sensor, and the output terminal of the controller is electrically connected to the electromagnetic reversing valve. The controller is used to control the electromagnetic reversing valve to change the flow path of the exhaust gas.

[0009] By adopting the above technical solution, as the particulate filter adsorbs fixed particles in the exhaust gas, the gas pressure on both sides of the particulate filter can be monitored by the gas pressure sensor to determine the degree of blockage of the particulate filter. When the blockage of the particulate filter reaches the point where it needs to be replaced, the controller controls the electromagnetic reversing valve to introduce the exhaust gas into another air duct, thereby improving the convenience of replacing the particulate filter.

[0010] In one specific implementation, each of the air guide tubes is provided with an installation port, which divides the air guide tube into two sections. The installation port is located between the two fixing collars. Each section of the air guide tube is slidably fitted with a sealing tube, and the two sealing tubes abut against each other to seal the installation port.

[0011] By adopting the above technical solution, the air duct is divided into two sections by setting an installation port, which can improve the convenience of installing and replacing the particulate filter. After the particulate filter is installed, the installation port is sealed by two sealing tubes, which can improve the sealing performance of the pipeline at the particulate filter installation site.

[0012] In one specific implementation, the bracket is provided with a linear drive mechanism located below the mounting port. The linear drive mechanism is provided with a placement plate, and the placement plate has a placement slot for placing the particulate trap. The linear drive mechanism can transport the particulate trap into the mounting port, so that the mounting ring is aligned with the fixing collar. Two connecting rods are rotatably provided on the placement plate, and the connecting rods correspond one-to-one with the sealing tubes. The connecting rods are rotatably configured with the sealing tubes and are used to push or pull the sealing tubes to slide. The sealing tubes are provided with disassembly parts for pushing the two fixing collars away from each other. The air guide tube is provided with guide parts for guiding the disassembly parts to disengage from the fixing collars.

[0013] By adopting the above technical solution, when replacing the particulate filter, the particulate filter is first placed in the placement slot on the placement plate. Then, the linear drive mechanism drives the placement plate to move towards the installation port. At this time, the placement plate pushes the two sealing tubes away from each other through two connecting rods, so that the installation port slowly opens. When the sealing tubes open, the disassembly component drives the two fixing collars away from each other, and the fixing collars fall off to complete the disassembly. Then, the placement plate moves the new particulate filter into the installation port. The guide component guides the disassembly component to release the fixing collars. The fixing collars move closer to each other under the push of the support spring, so that the installation ring is inserted into the fixing collar. Then, the linear drive mechanism drives the placement plate to move down. The placement plate drives the two sealing tubes to move closer to each other through the connecting rods to seal the installation port, thereby completing the automatic replacement of the particulate filter and improving the convenience of particulate filter replacement.

[0014] In one specific implementation, the disassembly component includes a disassembly block slidably disposed on the inner wall of the sealing tube, the disassembly block sliding radially along the sealing tube, the disassembly block being able to extend onto the sliding trajectory of the retaining collar, and the disassembly block being able to push the retaining collar to slide.

[0015] By adopting the above technical solution, when the two mounting ports are opened, the two mounting plates move away from each other, and then the mounting plates move away from each other through the disassembly quick-release mechanism, thereby realizing the disassembly of the particulate trap.

[0016] In one specific implementation, the guide includes a guide surface disposed on the end wall of the air duct, the guide surface for the disassembly block to slide along the guide surface, the disassembly block to slide along the guide surface, thereby disengaging the disassembly block from the fixing collar, and a telescopic spring is provided inside the sealing tube, the telescopic spring being used to push the disassembly block to slide along the movement trajectory of the disassembly block.

[0017] By adopting the above technical solution, when the new particulate collector moves toward the installation port, the disassembly block begins to slide along the guide surface and slides toward the outside of the air duct. The telescopic spring contracts, causing the disassembly block to gradually separate from the fixing collar. When the new particulate collector is aligned with the fixing collar, the disassembly block separates from the fixing collar, and the fixing collar moves closer to each other under the push of the support spring, so that the installation ring is inserted into the fixing collar, thereby realizing the automatic installation of the new particulate collector.

[0018] In one specific implementation, the placement plate is provided with a guide plate for guiding the particulate trap that falls into the installation port. The guide plate is rotatably disposed on the placement plate, and one end of the guide plate extends above the particulate trap on the placement plate. The placement plate is provided with a return spring, which is connected to the guide plate.

[0019] By adopting the above technical solution, when the old particulate trap is removed, it falls onto the guide plate and is guided along the guide plate to the collection point. After the new particulate trap is installed, the placement plate moves down, and the guide plate rotates under the obstruction of the new particulate trap. Then the guide plate passes over the new particulate trap and returns to its original position under the pull of the return spring. This effectively prevents the old particulate trap from falling onto the new particulate trap and damaging it.

[0020] In one specific implementation, the sealing tube has a sealing ring groove on the end wall near the other sealing tube, and a high-temperature resistant sealing gasket is provided on the bottom wall of the sealing ring groove. The other sealing tube has a sealing ring strip on its end wall, and the sealing ring strip can be inserted into the sealing ring groove and squeeze the high-temperature resistant sealing gasket.

[0021] By adopting the above technical solution, when the two sealing tubes approach each other, the sealing ring strip on one sealing tube is inserted into the sealing ring groove on the other sealing tube. Then, the sealing ring strip squeezes the high-temperature resistant sealing gasket to deform and squeeze the inner wall of the sealing ring groove, thereby improving the sealing performance at the connection of the two sealing tubes and effectively preventing exhaust gas leakage.

[0022] In one specific implementation, the support is provided with a feeding rack for placing a plurality of the particulate traps, one end of the feeding rack extending to the placement plate, and the feeding rack being inclined toward the placement plate so that the particulate traps can roll into the placement slot.

[0023] By adopting the above technical solution, when adding particulate traps to the placement plate, multiple particulate traps are first placed on the feeding rack. The particulate traps are arranged and moved towards the placement slot. When the placement plate returns to its original position after installing a particulate trap, the particulate trap rolls into the placement slot under the action of gravity, thereby realizing automatic feeding of particulate traps and improving the convenience of adding particulate traps.

[0024] In one specific implementation, the feeding rack is provided with two slidably mounted baffles, and the particle collector can roll between the two baffles. The baffles pass through the feeding rack. A rotating rod is rotatably mounted on the support, and the rotating rod is provided with a sliding groove. The sliding groove is arranged along the length direction of the rotating rod. The baffles are provided with sliders for sliding within the sliding groove. The two sliders are located on both sides of the rotation point of the rotating rod. The rotating rod can drive the two baffles to move in opposite directions. A support spring is provided on the support, and the support spring is connected to the rotating rod. The placement plate can compress the rotating rod to rotate, and the support spring is used to push the rotating rod back to its original position.

[0025] By adopting the above technical solution, when feeding the particulate trap, initially, the telescopic spring pushes the rotating rod to a stationary position, and the particulate trap is placed and blocked by the front stop. Then, when the placement plate descends to its original position, the placement plate pushes the rotating rod to rotate, and the rotating rod drives the front stop of the particulate trap to move down, while the rear stop of the particulate trap moves up, blocking the rear particulate trap. As the front stop of the particulate trap moves down, the particulate trap contacts the restriction and rolls into the placement slot on the placement plate, thereby realizing the automatic filling of the particulate trap.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When the diesel generator is generating electricity, the exhaust gas is transported to the air guide pipe through the exhaust pipe of the diesel generator. As the support spring presses the fixing ring against the mounting ring, the exhaust gas is discharged after passing through the particulate filter. When the exhaust gas passes through the particulate filter, the solid particulate matter in the exhaust gas is adsorbed, thereby removing the black smoke in the exhaust gas, which can improve the concealment of civil defense works in wartime.

[0028] 2. When replacing the particulate filter, the particulate filter automatically rolls into the placement slot under gravity. Then, the linear drive mechanism drives the placement plate toward the installation port, and pushes the two sealing tubes away from each other through two connecting rods, causing the installation port to slowly open. When the sealing tubes open, the disassembly block drives the two fixing collars away, and the fixing collars fall off to complete the disassembly. Then, the placement plate moves the new particulate filter into the installation port. The guide surface slides along the second guide surface, causing the disassembly block to disengage from the fixing collars. The fixing collars move closer together under the push of the support spring, so that the installation ring is inserted into the fixing collar. Then, the linear drive mechanism drives the placement plate to move down. The placement plate moves the two sealing tubes closer together through the connecting rods to seal the installation port, thereby completing the automatic replacement of the particulate filter and improving the convenience of particulate filter replacement.

[0039] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0040] This application discloses a smoke elimination and cooling device.

[0041] Reference Figure 1 , Figure 2 and Figure 3A smoke elimination and cooling device includes at least two air ducts 21, which are mounted on a support 6. In this embodiment, there are two air ducts 21. Each air duct 21 is connected to the exhaust pipe of a diesel generator 1 via an electromagnetic reversing valve 22. The electromagnetic reversing valve 22 controls one of the air ducts 21 to connect to the exhaust pipe of the diesel generator 1. Each air duct 21 is equipped with a particulate trap 3. Both ends of the particulate trap 3 are fitted with mounting rings 31, which are integrally manufactured with the particulate trap 3. Each air duct 21 has an installation port 23, which divides the air duct 21 into two sections. Each section of the air duct 21 is fixedly equipped with a retaining ring 24. The retaining ring 24 is located at the mounting port 23. On both sides of the port 23, two fixing rings 25 are slidably provided in each air guide tube 21. The two fixing rings 25 are located on both sides of the mounting port 23, and each fixing ring 25 is located between the mounting port 23 and the retaining ring 24. Each fixing ring 25 can extend into the mounting port 23. The opposite sides of the two fixing rings 25 are recessed to form stepped grooves 251. The mounting ring 31 can be inserted into the stepped grooves 251. Each fixing ring 25 and the retaining ring 24 are connected by multiple support springs 26. One end of the support spring 26 is fixedly connected to the retaining ring 24, and the other end of the support spring 26 is fixedly connected to the fixing ring 25. The support spring 26 can push the fixing ring 25 to squeeze the mounting ring 31.

[0042] When installing the particulate trap 3, insert the particulate trap 3 into the air duct 21 through the installation port 23, then insert the installation ring 31 into the stepped groove 251 in the fixing collar 25, and then push the fixing collar 25 to squeeze the installation ring 31 by the support springs 26 on both sides of the particulate trap 3, thereby completing the installation of the particulate trap 3.

[0043] When the diesel generator 1 generates electricity, the exhaust gas is transported to the air guide pipe 21 through the exhaust pipe of the diesel generator 1. Since the mounting ring 31 is inserted into the fixing collar 25 and the support spring 26 presses the fixing collar 25 against the mounting ring 31, the exhaust gas is discharged after passing through the particulate filter 3. When the exhaust gas passes through the particulate filter 3, the solid particulate matter in the exhaust gas is adsorbed, thereby removing the black smoke in the exhaust gas, which can improve the concealment of civil defense works in wartime.

[0044] Reference Figure 2 , Figure 3 Each gas duct 21 is equipped with two gas pressure sensors 4, which are located on both sides of the particulate trap 3. The electromagnetic reversing valve 22 is equipped with a controller. The input end of the controller is electrically connected to the gas pressure sensor 4. The gas pressure sensor 4 serves as the signal output module of the controller. The output end of the controller is electrically connected to the electromagnetic reversing valve 22. The controller controls the electromagnetic reversing valve 22 to change the flow channel of the exhaust gas.

[0045] As the particulate filter 3 adsorbs fixed particles in the exhaust gas, the gas pressure on both sides of the particulate filter 3 is monitored by the gas pressure sensor 4, which can determine the degree of blockage of the particulate filter 3. When the particulate filter 3 is blocked to the point of needing replacement, the controller controls the solenoid reversing valve 22 to introduce the exhaust gas into another air duct 21, thereby improving the convenience of replacing the particulate filter 3.

[0046] Reference Figure 1 Each air duct 21 is wrapped with a cooling water pipe 5, which is located on the side of the installation port 23 near the diesel generator 1. Cooling water is introduced into the cooling water pipe 5 to cool the exhaust gas discharged from the exhaust pipe, thereby reducing the temperature of the exhaust gas entering the ventilation system and improving the concealment of the civil defense works.

[0047] Reference Figure 4 The bracket 6 is equipped with a linear drive mechanism 61. In this embodiment, the linear drive mechanism 61 is a hydraulic cylinder, but in other embodiments it can also be a pneumatic cylinder, electric cylinder, etc. The linear drive mechanism 61 is located below the mounting port 23, and the output shaft of the linear drive mechanism 61 faces upward. A placement plate 62 is fixedly mounted on the output shaft of the linear drive mechanism 61. The placement plate 62 is provided with a placement groove 621 for placing the particulate collector 3. The linear drive mechanism 61 can transport the particulate collector 3 into the mounting port 23, so that the mounting ring 31 and the particulate collector 3 can be placed in the mounting port 23. The fixed collars 25 are aligned, and each air guide tube 21 is fitted with a sealing tube 71 on both ends. The sealing tube 71 and the air guide tube 21 are slidably sealed. Two connecting rods 63 are hinged on the placement plate 62. The hinge point between the two connecting rods 63 and the placement plate 62 is located below the placement plate 62. The connecting rods 63 and the sealing tubes 71 correspond one-to-one. The connecting rods 63 and the sealing tubes 71 are rotatably connected. When the linear drive mechanism 61 drives the placement plate 62 to move up and down, the connecting rods 63 pull the two sealing tubes 71 closer to each other or further away.

[0048] Reference Figure 5 , Figure 6The sealing tube 71 is provided with a disassembly component 64 for pushing the two fixed collars 25 away from each other. The air guide tube 21 is provided with a guide component 65 for guiding the disassembly component 64 to disengage from the fixed collars 25. In this embodiment, the disassembly component 64 includes a disassembly block 641. There are two disassembly blocks 641, which are evenly arranged along the circumference of the sealing tube 71. Two spring cylinders 642 are provided on the outer wall of the sealing tube 71. One end of the spring cylinder 642 is open and the other end is sealed. The open end of the spring cylinder 642 is fixed to the sealing tube 71. The disassembly block 641 is inserted into the sealing tube 71 and slides with the sealing tube 71. One end of the disassembly block 641 extends through the spring cylinder 642. The disassembly block 641 can extend to the sliding trajectory of the fixed collar 25. Each spring cylinder 642 is provided with a telescopic spring 643. One end of the telescopic spring 643 is fixedly connected to the disassembly block 641, and the other end is fixedly connected to the spring cylinder 642. The disassembly block 641 can push the fixed collar 25 to slide.

[0049] Reference Figure 5 , Figure 6 The disassembly block 641 includes a protrusion 6411 and a base 6412. The base 6412 is fixedly connected to the telescopic spring 643. The protrusion 6411 is located on the side of the base 6412 away from the telescopic spring 643. The protrusion 6411 can push the fixing collar 25 to slide. The guide 65 includes a guide surface 651, which is disposed on the side wall of the air duct 21 near the mounting port 23. The guide surface 651 extends from the inner side wall of the air duct 21 to the outer side wall towards... The side away from the installation port 23 is inclined, and the guide surface 651 is provided with a through groove 652 for the protrusion 6411 to be inserted. The through groove 652 extends to the inner wall of the air duct 21. The base 6412 can slide along the guide surface 651. When the base 6412 slides along the guide surface 651, the disassembly block 641 slides away from the spring cylinder 642. When the placement plate 62 aligns the particulate trap 3 with the fixing collar 25, the disassembly block 641 disengages from the fixing collar 25.

[0050] When replacing the particulate trap 3, first place the particulate trap 3 into the placement slot 621 on the placement plate 62. Then, the linear drive mechanism 61 drives the placement plate 62 to move towards the mounting port 23. At this time, the placement plate 62 pushes the two sealing tubes 71 away from each other through the two connecting rods 63, so that the mounting port 23 slowly opens. When the sealing tubes 71 open, the disassembly block 641 drives the two fixing collars 25 away, and the fixing collars 25 fall off to complete the disassembly. Then, the placement plate 62 moves the new particulate trap 3 into the mounting port 23. At this time, the sealing tube 71 continues to slide along the air guide tube 21, and the sealing tube 71 drives the disassembly block 641 to slide onto the guide surface 65. 1. When the disassembly block 641 slides along the guide surface 651, the protrusion 6411 slides toward the spring cylinder 642, and the telescopic spring 643 is compressed. When the particulate trap 3 is aligned with the fixing collar 25, the protrusion 6411 releases the restriction on the fixing collar 25. The fixing collar 25 moves closer to each other under the push of the support spring 26, so that the mounting ring 31 is inserted into the fixing collar 25. Then, the linear drive mechanism 61 drives the placement plate 62 to move down. The placement plate 62 drives the two sealing tubes 71 to move closer to each other through the connecting rod 63, sealing the mounting port 23, thereby completing the automatic replacement of the particulate trap 3 and improving the convenience of replacing the particulate trap 3.

[0051] Reference Figure 5 , Figure 7 A sealing ring groove 72 is provided on the end wall of the sealing tube 71 near the other sealing tube 71. A high-temperature resistant sealing gasket 73 is provided on the bottom wall of the sealing ring groove 72. In this embodiment, the high-temperature resistant sealing gasket 73 is an asbestos gasket. In other embodiments, it can also be a metal-coated gasket, a graphite gasket, etc. A sealing ring strip 74 is formed by protruding outward on the end wall of the other sealing tube 71. The sealing ring strip 74 can be inserted into the sealing ring groove 72 and squeeze the high-temperature resistant sealing gasket 73.

[0052] When the two sealing tubes 71 approach each other, the sealing ring strip 74 on one sealing tube 71 is inserted into the sealing ring groove 72 on the other sealing tube 71. Then, the sealing ring strip 74 squeezes the high-temperature resistant sealing gasket 73 to deform and squeeze the inner wall of the sealing ring groove 72, thereby improving the sealing performance at the connection of the two sealing tubes 71 and effectively preventing exhaust gas leakage.

[0053] Reference Figure 8 , Figure 9The placement plate 62 is provided with a guide plate 81. One end of the guide plate 81 is rotatably connected to the placement plate 62 via a hinge shaft, and the other end of the guide plate 81 extends to the top of the placement plate 62. A space for the particle trap 3 is formed between the guide plate 81 and the placement plate 62. The placement plate 62 is provided with a limiting plate 82, which is located on the side of the placement groove 621 near the guide plate 81. The placement plate 62 is provided with a return spring 83, one end of which is fixedly connected to the guide plate 81, and the other end is fixedly connected to the placement plate 62. Initially, the return spring 83 pulls the limiting plate 82 to abut against the placement plate 62.

[0054] When the old particulate trap 3 is removed, it falls onto the guide plate 81 and is guided along the guide plate 81 to the collection point. After the new particulate trap 3 is installed, the placement plate 62 moves down, and the guide plate 81 rotates under the obstruction of the new particulate trap 3. Then the guide plate 81 passes over the new particulate trap 3 and returns to its original position under the pull of the return spring 83. This effectively prevents the old particulate trap 3 from falling onto the new particulate trap 3 and damaging it.

[0055] Reference Figure 8 The support 6 is equipped with a feeding rack 84 for placing multiple particulate traps 3. The feeding rack 84 is inclined, and its lowest end extends to the placement plate 62, allowing the particulate traps 3 to roll into the placement groove 621. The feeding rack 84 is equipped with two sliding stop bars 841, which are arranged back and forth along the rolling direction of the particulate traps 3, allowing the particulate traps 3 to roll between the two stop bars 841. The stop bars 841 pass through the feeding rack 84. The support 6 is equipped with a rotating rod 842, which is equipped with a sliding groove 843 along the length of the rotating rod 842. The stop bar 841 is equipped with a slider 844 for sliding within the slide groove 843. The two sliders 844 are located on both sides of the rotation point of the rotating rod 842. The rotating rod 842 can drive the two stop bars 841 to move in opposite directions. The bracket 6 is equipped with a drive spring 845. One end of the drive spring 845 is fixedly connected to the rotating rod 842. A push rod 846 for pushing the rotating rod 842 to rotate is fixedly provided below the placement plate 62. When the placement plate 62 presses down on the rotating rod 842, the rotating rod 842 drives the front stop bar 841 to move down and the rear stop bar 841 to move up. The support spring 26 is used to push the rotating rod 842 to return to its original position.

[0056] When feeding the particulate trap 3, initially, the drive spring 845 pushes the rotating rod 842 to a stationary position, and the particulate trap 3 is blocked by the front stop 841. Then, when the placement plate 62 descends to its original position, the placement plate 62 pushes the rotating rod 842 to rotate. At this time, the drive spring 845 contracts, and the rotating rod 842 causes the front stop 841 of the particulate trap 3 to move down, and the rear stop 841 of the particulate trap 3 to move up, blocking the rear particulate trap 3. When the stop bar 841 in front of the particle trap 3 moves down, the particle trap 3 is released from its restriction and rolls into the placement slot 621 on the placement plate 62. Then, when the placement plate 62 moves up, the drive spring 845 pushes the rotating rod 842 to rotate in the opposite direction. The rotating rod 842 drives the front stop bar 841 to move up and the rear stop bar 841 to move down, thereby causing the rear particle trap 3 to move forward. By continuously repeating the above process, the automatic filling of the particle trap 3 can be achieved, improving the convenience of adding the particle trap 3.

[0057] The implementation principle of the smoke elimination and cooling device in this application embodiment is as follows: When the diesel generator 1 generates electricity, the exhaust gas discharged is transported to the air guide pipe 21 through the exhaust pipe of the diesel generator 1. Since the mounting ring 31 is inserted into the fixing collar 25 and the support spring 26 presses the fixing collar 25 against the mounting ring 31, the exhaust gas is discharged after passing through the particulate trap 3. When the exhaust gas passes through the particulate trap 3, the solid particulate matter in the exhaust gas is adsorbed, thereby removing the black smoke in the exhaust gas, which can improve the concealment of civil defense works in wartime.

[0058] When replacing the particulate trap 3, first place the particulate trap 3 into the placement slot 621 on the placement plate 62. Then, the linear drive mechanism 61 drives the placement plate 62 to move towards the mounting port 23. At this time, the placement plate 62 pushes the two sealing tubes 71 away from each other through the two connecting rods 63, so that the mounting port 23 slowly opens. When the sealing tubes 71 open, the disassembly block 641 drives the two fixing collars 25 away, and the fixing collars 25 fall off to complete the disassembly. Then, the placement plate 62 moves the new particulate trap 3 into the mounting port 23. At this time, the sealing tubes 71 continue to slide along the air guide tube 21, and the sealing block drives the disassembly block 641 to slide onto the guide surface 651. When the disassembly block 641 slides along the guide surface 651, the protrusion 6411 slides toward the spring cylinder 642, and the telescopic spring 643 is compressed. When the particulate trap 3 is aligned with the fixing collar 25, the protrusion 6411 releases the restriction on the fixing collar 25. The fixing collar 25 moves closer to each other under the push of the support spring 26, so that the mounting ring 31 is inserted into the fixing collar 25. Then the linear drive mechanism 61 drives the placement plate 62 to move down. The placement plate 62 drives the two sealing tubes 71 to move closer to each other through the connecting rod 63, sealing the mounting port 23, thereby completing the automatic replacement of the particulate trap 3 and improving the convenience of replacing the particulate trap 3.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
