Description

Technical Field

[0001] The present invention relates to the technical field of exhaust gas treatment for diesel generators, and in particular to a diesel generator capable of filtering exhaust gas. Background Art

[0002] A diesel generator is a small power generation device that uses diesel as fuel and a diesel engine as the prime mover to drive the generator to generate electricity. During the power generation process, the diesel generator will emit a large amount of exhaust gas. Since it is difficult for the diesel engine to fully burn the diesel, the exhaust gas contains a large amount of harmful components and particulate matter, so the exhaust gas needs to be filtered;

[0003] The Chinese patent authorization announcement number is CN217939557U, and the name is an exhaust gas treatment device, including a joint pipe, one end of the joint pipe is connected to a gas collecting pipe, and the gas collecting pipe is connected to a filter pipe near the end of the joint pipe. The filter pipe is provided with a filtering mechanism inside the filter pipe, and the filtering mechanism includes a first filter screen and a second filter screen. This solution relies on the first filter screen and the second filter screen in the filtering mechanism to filter different particulate matter in the exhaust gas in sequence, thereby improving the cleanliness of the exhaust gas;

[0004] The shortcomings of the above-mentioned existing technical solutions are: in the above-mentioned solution, when the diesel generator processes the exhaust gas, it only relies on the first filter and the second filter to filter and block the particles of different sizes in the exhaust gas respectively, which is not convenient for capturing the particles in the exhaust gas, and the filtered particles are relatively limited, and the filtering effect is poor. At the same time, the mesh of the filter is easily blocked by particles, which is not convenient for timely treatment, resulting in the filter losing its filtering effect and being unable to be used continuously. Summary of the Invention

[0008] The bottom of the filter tube is connected to a recovery tube, and both the filter tube and the recovery tube are semicircular tubes. A driving motor is connected between the filter tube and the recovery tube. The main shaft end of the driving motor is connected to a circular filter plate, and the upper and lower ends of the circular filter plate are respectively connected to the filter tube and the recovery tube. A plurality of conical capture sleeves are evenly distributed on the circular filter plate.

[0009] The main shaft end of the driving motor is also connected to a driving gear, and a linkage gear is rotatably connected in the recovery pipe. One end of the linkage gear is engaged with the driving gear, and a plurality of extrusion grooves are opened on the circumference of the linkage gear;

[0011] As a further solution of the present invention: the elastic impact member includes an impact vertical plate and a force storage spring, the impact vertical plate is slidably connected to the strip chute, and the impact vertical plate and the strip chute are connected via the force storage spring.

[0012] As a further solution of the present invention: the blowing mechanism includes an elastic airbag and an oblique spray hole, and the elastic airbag is provided in plurality and evenly distributed on the impact vertical plate. One end of the elastic airbag is connected to an extrusion block, and the oblique spray hole is opened on the extrusion block and is distributed circumferentially in plurality.

[0013] As a further solution of the present invention: the conical capture sleeve includes a connecting hole and an elastic support rod, the connecting hole is opened on the circular filter plate, and there are multiple connecting holes evenly distributed, the elastic support rod is connected in the connecting hole, and an elastic colloid is connected between the elastic support rod and the corresponding connecting hole.

[0014] As a further solution of the present invention: the extrusion groove includes an arc guide groove and a right-angle groove, and the arc guide groove and the right-angle groove are both opened on the outer wall of the linkage gear, and the arc guide groove and the right-angle groove match each other.

[0017] As a further solution of the present invention: the filter tube is threadedly connected to the tail gas pipe.

[0018] Beneficial effects of the present invention:

[0019] 1. When the exhaust gas generated by the operation of the diesel generator of the present invention passes through the filter tube, the distributed conical capture sleeves capture the particulate matter in the gas. Since the inner diameter of the conical capture sleeve becomes smaller laterally, it is convenient to capture particulate matter of various sizes. The conical capture sleeve that has captured the particulate matter enters the recovery tube as the circular filter plate rotates. The impact vertical plate provided in the recovery tube can be linked to move laterally to impact the conical capture sleeve during the rotation of the circular filter plate. Since the conical capture sleeve is composed of an elastic colloid and an elastic support rod, it is convenient to fold and deform during the impact process. At the same time, it relies on vibration to conveniently discharge the captured and attached particulate matter from the larger port, and then enter the filter tube along with the circular filter plate, continuously and repeatedly capturing and filtering the exhaust gas.

[0020] 2. The circular filter plate of the present invention is driven to rotate by a driving motor, and the driving motor can drive the linkage gear to rotate by the driving gear during operation. The extrusion grooves distributed on the linkage gear interact intermittently with the linkage ball connected to the impact vertical plate, thereby realizing the reciprocating motion of the impact vertical plate. Moreover, each time the impact vertical plate hits, the elastic force released by the storage spring can instantly and quickly hit the conical capture sleeve, so as to ensure the impact effect;

[0021] 3. The impact vertical plate of the present invention is distributed with elastic air bags, which are easy to compress during the impact process, so as to squeeze out the internal air and act on the conical capture sleeve, so as to rely on the air flow to blow off the attached particulate debris, thereby enhancing the separation effect of the particulate debris and the conical capture sleeve.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] like Figure 1-Figure 7 As shown, a diesel generator capable of exhaust gas filtration includes a diesel generator body 1, an exhaust pipe 2 is provided on the diesel generator body 1, and the exhaust pipe 2 is used to discharge the exhaust gas generated during the operation of the diesel generator body 1. A filter tube 3 is provided at the end of the exhaust pipe 2. The filter tube 3 is threadedly connected to the exhaust pipe 2 for easy disassembly and assembly. The end of the filter tube 3 is connected to an oxidation catalytic converter 4, which is used for oxidation-reduction treatment of gases such as carbon monoxide in the exhaust gas;

[0033] The bottom of the filter tube 3 is connected to a recovery tube 5, and the filter tube 3 and the recovery tube 5 are both semicircular tubes. A drive motor 11 is connected between the filter tube 3 and the recovery tube 5. The main shaft end of the drive motor 11 is connected to a circular filter plate 13, and the upper and lower ends of the circular filter plate 13 are respectively connected to the filter tube 3 and the recovery tube 5, and a transition tube is connected between the filter tube 3 and the recovery tube 5 to partially enclose the circular filter plate 13 between the filter tube 3 and the recovery tube 5. A plurality of conical capture sleeves 12 are evenly distributed on the circular filter plate 13, and the inner diameter of the conical capture sleeve 12 at one end close to the exhaust pipe 2 is 0. The circular filter plate 13 is relatively large, and its inner diameter gradually decreases from right to left. When the exhaust gas is discharged from the exhaust pipe 2, the exhaust gas first passes through the portion of the circular filter plate 13 in the filter tube 3 and passes through the distributed conical capture sleeve 12. Since the inner diameter of the conical capture sleeve 12 gradually decreases laterally, it is convenient to catch particles of various sizes and realize particulate matter capture; and the driving motor 11 continuously drives the circular filter plate 13 to rotate, so that the portion of the circular filter plate 13 in the filter tube 3 rotates into the internal space of the recovery tube 5, and the portion of the circular filter plate 13 originally in the internal space of the recovery tube 5 is transferred to the filter tube 3;

[0034] The conical capture sleeve 12 includes a connecting hole 19 and an elastic support rod 21. The connecting hole 19 is opened on the circular filter plate 13, and there are multiple connecting holes 19 evenly distributed. The elastic support rod 21 is connected to the connecting hole 19, and the elastic support rod 21 is bendable. Multiple elastic support rods 21 are circumferentially distributed in each connecting hole 19. An elastic colloid 20 is connected between the elastic support rod 21 and the corresponding connecting hole 19. The elastic colloid 20 and the elastic support rod 21 are combined to form a cone, which is convenient for capturing particulate matter. The elastic support rod 21 can be folded toward the larger end of the conical capture sleeve 12 under the action of external force, so as to facilitate the push out of the captured particulate debris and avoid blockage due to excessive accumulation.

[0035] The main shaft end of the driving motor 11 is also connected to a driving gear 8, and a linkage gear 7 is rotatably connected in the recovery tube 5. One end of the linkage gear 7 passes through the recovery tube 5 and meshes with the driving gear 8. A plurality of extrusion grooves 9 are opened on the circumference of the linkage gear 7. The extrusion grooves 9 include circular arc guide grooves 22 and right-angle grooves 23. The circular arc guide grooves 22 and the right-angle grooves 23 are both opened on the outer wall of the linkage gear 7, and the circular arc guide grooves 22 and the right-angle grooves 23 cooperate together to form a complete special-shaped groove body;

[0036] An elastic impact member is vertically provided inside the recovery pipe 5, and a strip slide 14 is horizontally opened at the bottom of the recovery pipe 5, and the elastic impact member is slidably connected to the strip slide 14, and the elastic impact member includes an impact vertical plate 16 and a force storage spring 15, and the impact vertical plate 16 is slidably connected to the strip slide 14, and the impact vertical plate 16 is connected to the strip slide 14 through the force storage spring 15, and the impact vertical plate 16 is aligned with the circular filter plate 13 on the inside of the recovery pipe 5, and one side of the elastic impact member is connected to a linkage ball 6 that cooperates with the extrusion groove 9 through a rod body, and the linkage ball 6 includes a hemisphere 24 and a square body 25, which are connected together, and the hemisphere 24 is connected to the elastic impact member, the hemisphere 24 cooperates with the circular arc guide groove 22, the square body 25 cooperates with the right-angle groove 23, and the overall width of the linkage ball 6 is smaller than the width of the extrusion groove 9;

[0037] When the driving motor 11 is running, the driving motor 11 drives the driving gear 8 to rotate counterclockwise, and the driving gear 8 drives the meshing linkage gear 7 to rotate clockwise. During the rotation of the linkage gear 7, the linkage ball 6 is in contact with the outer wall of the linkage gear 7, and when the linkage ball 6 is in contact with the position other than the extrusion groove 9, the storage spring 15 is in a stretched state. When the linkage ball 6 coincides with the extrusion groove 9, the block 25 on the linkage ball 6 is directly embedded in the corresponding right-angle groove 23, which facilitates the instantaneous release of the storage spring 15, thereby facilitating the impact vertical plate 16 to move horizontally along the strip slide 14 and hit the part of the circular filter plate 13 in the recovery pipe 5, and hit the conical capture sleeve 12 distributed on this part of the circular filter plate 13, causing the conical capture sleeve 12 to vibrate, shaking off the captured particles, and at the same time, the smaller end of the conical capture sleeve 12 will also be affected When the linkage ball 6 is squeezed, each elastic support rod 21 is folded, which promotes the separation of particles. Under the action of the continued rotation of the linkage gear 7, the hemispherical body 24 on the linkage ball 6 cooperates with the circular arc guide groove 22 in the corresponding extrusion groove 9. Sliding extrusion occurs between the circular arc guide groove 22 and the hemispherical body 24, which facilitates the generation of lateral extrusion force on the linkage ball 6, thereby facilitating the linkage ball 6 to slide out of the corresponding extrusion groove 9. During the sliding out process, the linkage ball 6 drives the impact vertical plate 16 to move laterally away from the circular filter plate 13, so that the storage spring 15 is stretched and stored again. When the linkage ball 6 coincides with the next extrusion groove 9, the impact vertical plate 16 is repeated. The impact movement is repeated so that the impact vertical plate 16 repeatedly hits the circular filter plate 13 in the recovery pipe 5, making it convenient to discharge the particle debris captured by the conical capture sleeve 12 from the filter tube 3, thereby facilitating continuous use.

[0038] The elastic impact member is also provided with an air blowing mechanism, which includes an elastic airbag 17 and an oblique spray hole 18. A plurality of elastic airbags 17 are provided and are evenly distributed on the impact riser 16. The elastic airbag 17 is aligned with the conical capture sleeve 12 distributed on the circular filter plate 13 in the recovery pipe 5. One end of the elastic airbag 17 is connected to an extrusion block. The oblique spray holes 18 are provided on the extrusion block and are distributed in a plurality of directions. When the impact riser 16 hits the circular filter plate 13, the elastic airbags 17 distributed on the impact riser 16 are compressed due to the extrusion, and the corresponding conical capture sleeve 12 has not been deformed during this process. During the compression process of the elastic airbag 17, the air inside it is ejected through each oblique spray hole 18. The airflow ejected from the oblique spray hole 18 acts conveniently on the inner side of the corresponding conical capture sleeve 12, thereby making it easy to blow off the attached particulate debris.

[0039] A circular air hole is provided at one end of the recovery pipe 5 to facilitate air replenishment inside the recovery pipe 5;

[0040] A drawer box 10 is slidably inserted into one side of the recovery pipe 5 close to the larger end of the conical capture sleeve 12. The drawer box 10 is convenient for catching the granular debris separated from the conical capture sleeve 12, which is convenient for regular centralized cleaning.

[0041] The working principle of the present invention is as follows: the exhaust gas generated during the operation of the diesel generator body 1 is discharged into the filter tube 3 through the exhaust pipe 2. The discharged exhaust gas first passes through the circular filter plate 13 located in the filter tube 3 and passes through the distributed conical capture sleeve 12. Since the inner diameter of the conical capture sleeve 12 gradually decreases laterally, it is convenient to catch particles of various sizes, thereby achieving particulate matter capture;

[0042] The driving motor 11 continuously drives the circular filter plate 13 to rotate, so that the portion of the circular filter plate 13 in the filter tube 3 rotates into the internal space of the recovery tube 5, while the portion of the circular filter plate 13 originally in the internal space of the recovery tube 5 rotates into the filter tube 3;

[0043] When the gear 7 is in the process of rotating, the driving motor 11 drives the driving gear 8 to rotate counterclockwise, and the driving gear 8 drives the meshing linkage gear 7 to rotate clockwise. When the linkage gear 7 rotates, the linkage ball 6 is in contact with the outer wall of the linkage gear 7, and when the linkage ball 6 is in contact with the position other than the extrusion groove 9, the storage spring 15 is in a stretched state. When the linkage ball 6 coincides with the extrusion groove 9, the block 25 on the linkage ball 6 is directly engaged in the corresponding right-angle groove 23, which facilitates the instantaneous release of the storage spring 15, thereby facilitating the impact vertical plate 16 to move horizontally along the strip slide 14 and hit the part of the circular filter plate 13 in the recovery pipe 5, hitting the conical capture sleeve 12 distributed on this part of the circular filter plate 13, causing the conical capture sleeve 12 to vibrate and shake off the captured particles.

[0044] When the impact riser 16 hits the circular filter plate 13, the elastic airbags 17 distributed on the impact riser 16 are compressed due to extrusion, and the corresponding conical capture sleeve 12 has not yet deformed during this process. During the compression process of the elastic airbag 17, the air inside it is ejected through each inclined nozzle hole 18. The airflow ejected from the inclined nozzle hole 18 acts conveniently on the inner side of the corresponding conical capture sleeve 12, thereby facilitates blowing off the attached particles and debris;

[0045] After the elastic airbag 17 is compressed, it hits the vertical plate 16 and continues to squeeze, so that the elastic support rod 21 on the conical capture sleeve 12 is squeezed and folded toward the larger end of the conical capture sleeve 12, thereby facilitating the ejection of captured particles and preventing excessive accumulation and blockage. In this way, the particles captured by the conical capture sleeve 12 are discharged into the recovery pipe 5. The conical capture sleeve 12 that separates the particles enters the filter tube 3 as the circular filter plate 13 rotates and continues to work.

[0046] When the driving motor 11 indirectly drives the linkage gear 7 to rotate continuously, the hemisphere 24 on the linkage ball 6 cooperates with the circular arc guide groove 22 in the corresponding extrusion groove 9, and sliding extrusion occurs between the circular arc guide groove 22 and the hemisphere 24, which facilitates the generation of lateral extrusion force on the linkage ball 6, thereby facilitating the linkage ball 6 to slide out of the corresponding extrusion groove 9. During the sliding out process, the linkage ball 6 drives the impact vertical plate 16 to move laterally away from the circular filter plate 13, so that the storage spring 15 stretches and stores force again. When the linkage ball 6 coincides with the next extrusion groove 9, the impact vertical plate 16 is repeated. This is repeated so that the impact vertical plate 16 repeatedly hits the circular filter plate 13 in the recovery pipe 5, thereby facilitating each conical capture sleeve 12 to capture particulate matter from the filter pipe 3 and then enter the recovery pipe 5 for discharge, so as to facilitate continuous use;

[0047] The exhaust gas after particulate matter removal then passes through the oxidation catalytic converter 4, where the carbon monoxide and other gases in the exhaust gas are oxidized and reduced before being discharged, thereby reducing environmental pollution.

[0048] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
