Description

Technical Field

[0001] This invention relates to the field of diesel generator technology, specifically to a diesel generator with exhaust gas filtration capability. Background Technology

[0002] Diesel generators, as commonly used emergency and mobile power supply devices, are widely used in data centers, hospitals, construction sites, ports, ships, outdoor operations, and many other scenarios. Their core function is to generate electricity by burning diesel fuel, which produces a large amount of exhaust gas during the power generation process. This exhaust gas has a complex composition, containing various harmful substances such as particulate matter, nitrogen oxides, carbon monoxide, and hydrocarbons. Particulate matter can harm the human respiratory system, nitrogen oxides can cause acid rain and photochemical smog, carbon monoxide is toxic, and hydrocarbons participate in the formation of photochemical smog, posing a serious threat to the ecological environment and human health. Currently, existing diesel generator exhaust gas treatment methods mostly use particulate filters or catalytic converters to filter the exhaust gas. However, existing diesel generators have the following shortcomings in practical use: Currently, the exhaust gas filtration devices equipped in diesel generators (such as DPF particulate filters, three-way catalytic converters, ceramic filters, etc.) significantly increase exhaust back pressure during operation, causing obstruction of engine exhaust and resulting in problems such as reduced output power, higher engine coolant temperature, and increased fuel consumption. Simultaneously, after prolonged use, the filter screen is easily clogged by carbon deposits and particulate matter in the exhaust gas, leading to a continuous increase in exhaust resistance, further exacerbating engine power loss and increased fuel consumption. Existing filter cleaning mechanisms generally suffer from simplistic operation and basic cleaning methods, only achieving basic cleaning and having limited effectiveness in removing highly adhesive sludge and carbon deposits. The cleaning intensity is mostly fixed and cannot be adaptively adjusted according to the degree of filter clogging and the real-time operating conditions of the engine. In addition, the overall shock absorption mechanism mostly adopts a spring structure with constant stiffness and damping, which cannot be dynamically adjusted according to the operating conditions, making it difficult to achieve a balance between overall shock absorption and noise reduction and using vibration to achieve dust removal. The device is not equipped with an adaptive exhaust bypass structure, which cannot divert and relieve pressure in time under high back pressure conditions, which can easily cause the engine to overload. The functional modules are independent of each other and lack mechanical coordination and closed-loop linkage, resulting in poor overall equipment operation stability, filter self-cleaning ability and operating condition adaptability, making it difficult to meet long-term reliable environmental protection and power requirements.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0019] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0020] Please see Figures 1-10This invention provides a technical solution: a diesel generator capable of filtering exhaust gas, comprising a base 1, an mounting plate 2 disposed above the base 1, and a diesel generator body 3 mounted on the upper surface of the mounting plate 2. A filter pipe 4 is fixed to the end of the exhaust pipe on the diesel generator body 3. It also includes telescopic cylinders 7, four of which are fixed at equal intervals between the mounting plate 2 and the base 1. Shock-absorbing springs 8 are installed at the bottom of the inner walls of the four telescopic cylinders 7. Back pressure adaptive damping adjustment components are disposed inside the mounting plate 2 and the telescopic cylinders 7. A filter screen 9 is bolted to one end of the filter pipe 4, and a rotating rod 10 and a bearing 17 are respectively bearing-connected inside the filter pipe 4. The rotating rod 10 penetrates the interior of the filter screen 9 and is located away from the driven frustum 1. One end of the base 1 extends into the interior of the bearing seat 17, and a ratchet assembly 16 is installed between the rotating rod 10 and the bearing seat 17. A turntable 15 is fixedly fitted on the outer side of the rotating rod 10, and a cleaning brush 14 is symmetrically connected to the outer side of the turntable 15. A driven frustum 11 is fitted on the outer side of one end of the rotating rod 10. A fixing plate 12 is fixedly connected to the left side of the upper surface of the base 1, and rollers 13 are rotatably connected at equal intervals on the side of the upper end of the fixing plate 12. The top of the fixing plate 12 extends into the interior of the filter tube 4. The driven frustum 11 contacts the outer side of the multiple rollers 13. The driven frustum 11 and the rotating rod 10 are connected by a limited sliding connection. An adaptive vibration cleaning assembly is provided inside the filter tube 4. A collection box 20 is fixedly opened at the bottom of the filter tube 4.

[0021] In one embodiment of the present invention, when the diesel generator body 3 is working, the fuel burns in the cylinder, pushing the piston to do work, driving the crankshaft to rotate and output power, while generating continuous vibration and emitting high-temperature exhaust gas. After the exhaust gas enters the filter pipe 4, the filter screen 9 intercepts particulate matter and carbon deposits, thus purifying the exhaust gas. At this time, the vibration generated by the diesel generator body 3 during operation drives the filter pipe 4 to vibrate as well. During this process, the telescopic cylinder 7 and the shock-absorbing spring 8 work together to form elastic support and buffer for the diesel generator body 3, effectively absorbing and attenuating the working vibration, realizing the overall machine vibration reduction and noise reduction, and improving the stability of equipment operation. Under the action of vibration, the friction between the multiple rollers 13 set on the fixed plate 12 and the mating surface drives the driven frustum 11 to rotate, thereby driving the rotating rod 10 and the cleaning brush 14 to rotate synchronously. With the help of the ratchet assembly 16, the cleaning brush 14 keeps rotating in one direction stably, thereby realizing continuous and efficient cleaning of the surface of the filter screen 9, thus effectively preventing carbon deposits and particulate matter from adhering and clogging the filter screen 9, and ensuring smooth exhaust.

[0022] The adaptive vibration cleaning assembly includes a drive plate 1801, which is fixedly connected to the bottom of the bypass valve 5 stem. The opposite ends of the two cleaning brushes 14 are slidably disposed in grooves inside the turntable 15 via sliders 1802. A return spring 1806 is installed between the end of the slider 1802 and the groove inside the turntable 15. Support plates 1803 are symmetrically fixedly connected to the outer side of the turntable 15. Movable plates 1804 are connected to the right sides of both support plates 1803. The bottom of the drive plate 1801 extends into the filter tube 4, and the side of the bottom of the drive plate 1801 is connected to the rear end of the driven frustum 11 via multiple ball bearings. The movable plate 1804 is hinged to the support plate 1804. A torsion spring is wound and fixed on the side of plate 1803 and at the connection position between the shaft end of movable plate 1804 and support plate 1803. A striking block 1805 is fixed on the side of one end of movable plate 1804, and a guide plate 1807 is hinged to the side of the other end of movable plate 1804. Guide blocks 1808 are bolted to the opposite ends of the two cleaning brushes 14. Push blocks 1809 are fixedly connected to the inner wall of filter tube 4 at equal angles. The guide plate 1807 is slidably disposed inside turntable 15, and the side of guide plate 1807 away from movable plate 1804 is located below slider 1802, and the side away from movable plate 1804 is inclined. The positions of guide block 1808 and push block 1809 correspond to each other.

[0023] As one embodiment of the present invention, during the unidirectional rotation of the cleaning brush 14, the guide block 1808 on it is subjected to intermittent compression by the guide structure on the inner wall of the filter tube 4, resulting in radial displacement. Under the synergistic action of the return spring 1806, the cleaning brush 14 can simultaneously perform axial reciprocating movement while rotating, forming a combined action of rotation and reciprocating cleaning. When the cleaning brush 14 is squeezed and displaced, it drives the slider 1802 to move synchronously and push the guide plate 1807 to generate displacement. Through lever transmission, the movable plate 1804 swings around the fulcrum, which in turn drives the striking block 1805 to periodically strike the cleaning brush 14. Under the reset action of the torsion spring, the striking block 1805 reciprocates and strikes, causing the cleaning brush 14 to generate high-frequency vibration, shaking off the attached impurities and carbon deposits into the collection box 20 for centralized collection. This makes the cleaning of carbon deposits and adhesive impurities on the surface and in the pores of the filter screen 9 more thorough, effectively solving the problem of single action and incomplete dust removal in traditional cleaning mechanisms. At the same time, the valve stem synchronously drives the drive plate 1801 to move. The drive plate 1801 drives the driven truncated cone 11 to move horizontally along the axis of the rotating rod 10, realizing stepless speed regulation of the cleaning brush 14. This automatically increases the cleaning speed and optimizes shock absorption and damping under high load and high back pressure conditions, taking into account both the dust removal effect and the overall stability of the machine.

[0024] The back pressure adaptive damping adjustment assembly includes a linkage plate 1901, which is fixedly connected to the bottom of the bypass valve 5 stem. An adjustment block 1904 is slidably connected inside the telescopic cylinder 7 at the top of the shock-absorbing spring 8, and a vertical rod is fixedly connected to the top of the adjustment block 1904. A movable plate 1902 is provided inside the mounting plate 2, and the lower surface of the movable plate 1902 is connected to the top of the vertical rods on the four adjustment blocks 1904 through a connecting plate 1903. A wedge block 1905 is bolted to the left side of the movable plate 1902 and the side of the bottom of the linkage plate 1901. The lower surface of the adjustment block 1904 is fixedly connected to the top of the shock-absorbing spring 8. Both ends of the connecting plate 1903 are hinged to the opposite surfaces of the movable plate 1902 and the vertical rods on the adjustment blocks 1904.

[0025] In one embodiment of the present invention, when the diesel generator body 3 is running under high power conditions, the exhaust pressure inside the filter pipe 4 increases accordingly. Under the action of pressure, the bypass valve 5 automatically opens, and part of the exhaust gas is diverted and discharged through the pressure relief pipe 6 to achieve pressure relief and drag reduction (a coarse filter can also be added to the bypass port to prevent direct discharge of black smoke); the valve stem generates axial displacement under the drive of airflow and pressure, and drives the linkage plate 1901 to move synchronously, so that the wedge block 1905 on the linkage plate 1901 presses the matching wedge block 1905 on the moving plate 1902, driving the moving plate 1902 to generate a corresponding displacement; the deflection is transmitted through the connecting plate 1903, pushing the adjusting block 1904 to move downward and press the damping spring 8, realizing the adaptive adjustment of the damping of the damping spring 8.

[0026] Working Principle: When using this diesel generator that can filter exhaust gas, the vibration generated by the main body 3 of the diesel generator during operation is used to provide elastic buffering and shock absorption for the entire machine through the cooperation of the telescopic cylinder 7 and the shock-absorbing spring 8, thereby reducing vibration and noise and improving operational stability. Simultaneously, the vibration causes the roller 13 on the fixed plate 12 to rub against the mating surface, driving the driven frustum 11 to rotate. This rotation is then driven by the rotating rod 10 to rotate the cleaning brush 14. The ratchet assembly 16 ensures the stable unidirectional operation of the cleaning brush 14, continuously cleaning the surface of the filter screen 9 to prevent carbon deposits and particulate matter blockage. Then, as the cleaning brush 14 rotates, its guide block 1808 is squeezed by the guide structure on the inner wall of the filter tube 4 and works in conjunction with the return spring 1806 to achieve a combined cleaning process of rotation and axial reciprocating motion. The displacement of the cleaning brush 14 drives the slider 1802 to push the guide plate 1. 807. The striking block 1805 is driven by levers and torsion springs to reciprocate and strike the cleaning brush 14, causing the cleaning brush 14 to vibrate at high frequency, shaking off impurities and carbon deposits to the collection box 20 for centralized collection, resulting in more thorough dust removal. Then, when the generator operates at high power, causing the exhaust pressure in the filter pipe 4 to rise, the bypass valve 5 automatically opens, and some exhaust gas is diverted and depressurized through the pressure relief pipe 6. The axial movement of the valve stem drives the linkage plate 1901, which uses the inclined surface of the wedge block 1905 to drive the moving plate 1902 and the connecting plate 1903, pushing the adjusting block 1904 to squeeze the shock-absorbing spring 8, realizing adaptive damping adjustment. At the same time, the valve stem drives the drive plate 1801 to move the driven truncated cone 11 axially, realizing stepless speed change of the cleaning mechanism, automatically increasing the cleaning speed under high back pressure conditions, and balancing the dust removal effect and equipment operation stability.
