Description

Technical Field

[0001] This utility model relates to the field of exhaust gas separation, and in particular to a diesel engine exhaust gas recirculation and separation device. Background Technology

[0002] Diesel engines are widely used in commercial vehicles, construction machinery, and ships due to their high thermal efficiency and power performance. However, they also emit large amounts of pollutants such as nitrogen oxides and particulate matter. Diesel engine exhaust gas recirculation and separation devices can recirculate and treat the exhaust gas emitted by diesel engines, efficiently removing various solid particulate matter, harmful chemicals, and moisture contained in the exhaust gas.

[0003] By reintroducing some of the exhaust gases from engine combustion into the intake system, mixing them with fresh air, and then re-entering the combustion chamber for combustion, the combustion temperature and oxygen content in the combustion chamber can be reduced. Exhaust gas treatment often involves adding simple chemical reagents to the exhaust system in an attempt to reduce its content through chemical reactions during the exhaust process.

[0004] The carbon soot particles, metal debris, and unburned fuel components contained in the exhaust gas will adhere to the surface and internal pores of the filter element in large quantities during long-term filtration. The pores of the filter element will gradually become blocked, resulting in increased gas flow resistance. This not only affects the normal working efficiency of the exhaust gas recirculation system, but also makes the engine intake air volume unstable, which in turn affects the combustion effect and power output. Cleaning the filter element requires disassembling it, which affects the equipment maintenance efficiency. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-3This utility model provides an embodiment: a diesel engine exhaust gas recirculation separation device, including a separation chamber 101, a rotary knob 104, and a cleaning assembly. A support frame 102 is fixedly connected inside the separation chamber 101, and a filter element 103 is disposed below the support frame 102. A rotary knob 104 is disposed outside the separation chamber 101. A bevel gear 105 is disposed inside the separation chamber 101, and the rotary knob 104 is rotatably connected to the bevel gear 105. A second bevel gear 106 is rotatably connected inside the separation chamber 101, meshing with the first bevel gear 105. A threaded rod 107 is rotatably connected above the second bevel gear 106, and a sliding block 108 is slidably connected above the threaded rod 107. A cleaning brush 109 is fixedly connected to one side of the sliding block 108. The cleaning brush 109 abuts against the outer side of the filter element 103. A cleaning scraper 201 is fixedly connected to the other side of the sliding block 108. The cleaning scraper 201 abuts against the inner wall of the separation chamber 101. By adjusting the rotary knob 104, the bevel gear 105 is driven to rotate. The rotation of the bevel gear 105 drives the bevel gear 106 to rotate. The rotation of the bevel gear 106 drives the threaded rod 107 to rotate. The rotation of the threaded rod 107 drives the sliding block 108 to move linearly above the threaded rod 107. This allows the cleaning brush to clean the filter element 103 from the outside and the cleaning scraper 201 to clean the inner wall of the separation chamber 101. This keeps the filter element 103 and the separation chamber 101 clean, prevents the filter element 103 from becoming clogged, maintains the stability of the exhaust gas flow, and allows the exhaust gas to be separated efficiently.

[0023] Please see Figures 1-3In this embodiment, a through hole is provided above the separation chamber 101, and a first connecting pipe 202 is provided inside the through hole. A spray head 203 is provided below the first connecting pipe 202. A suction pump 204 is fixedly connected to the other side of the first connecting pipe 202, and a cleaning liquid tank 205 is fixedly connected to the other side of the suction pump 204. A fixing frame 206 is provided below the suction pump 204. A support leg 207 is fixedly connected to the lower part of the separation chamber 101. A feed pipe 208 is provided on one side of the separation chamber 101. A motor 301 is provided above the separation chamber 101. A rotating rod 302 is provided at the output end of the motor 301. A rotating blade 303 is provided above the rotating rod 302. An air outlet pipe 304 is fixedly connected to one side of the separation chamber 101. When cleaning the core 103 and the separation chamber 101, the cleaning liquid in the cleaning liquid tank 205 is introduced into the spray head 203 through the first connecting pipe 202 by starting the suction pump 204. Then, the cleaning liquid is sprayed from the spray head 203 into the interior of the separation chamber 101, which can more thoroughly clean the oil stains on the inner wall of the separation chamber 101. After cleaning, the waste liquid is discharged through the discharge pipe. The motor 301 is started to rotate the rotating rod 302. The rotation of the rotating rod 302 drives the rotating blade 303 to rotate. The high-speed rotation of the rotating blade 303 can accelerate the flow and mixing of waste gas in the separation chamber 101, enhance the centrifugal separation effect. At the same time, during the cleaning process, the airflow generated by the rotating blade 303 helps the cleaning liquid to be evenly distributed in the separation chamber 101, improving the cleaning efficiency and effect.

[0024] Please see Figures 4-6In this embodiment, a filter box 305 is provided on one side of the air outlet duct 304. A second support leg 306 is fixedly connected to the lower part of the filter box 305. A through groove is provided on the upper part of the filter box 305. A push plate 307 is provided inside the through groove. An activated carbon box 308 is provided below the push plate 307, and the size of the activated carbon box 308 is equal to the size of the through groove. An air outlet 309 is provided on one side of the filter box 305. A first connecting plate 401 is fixedly connected inside the filter box 305. A spring 402 is fixedly connected above the first connecting plate 401. A filter plate 404 is fixedly connected to the other side of the spring 402. A second connecting plate 403 is provided on the other side of the filter plate 404. A second motor 405 is provided on the outer side of the filter box 305. Inside filter box 305, there is a rotating rod 406. The output end of motor 405 is connected to the rotating rod 406. A rotating plate 407 is fixedly connected to the other side of the rotating rod 406. A rotating rod 408 is rotatably connected above the rotating plate 407. A sliding column 409 is provided on one side of the rotating rod 408. Inside filter box 305, there is a column 501. A fixing buckle 502 is fixedly connected above the column 501. A rotating frame 503 is rotatably connected above the column 501. A fixing rod 504 is provided on one side of the rotating frame 503, and the sliding column 409 slides above the fixing rod 504. A striking column 505 is provided on one side of the rotating frame. When motor 405 is started, it drives the rotating rod 406 to rotate. The rotating plate 407 rotates, which in turn rotates the rotating rod 408. The rotating rod 408 then causes the sliding column 409 to move linearly above the fixed rod 504. This linear movement of the sliding column 409 allows the rotating frame 503 to rotate around the column 501 via a rotating connection point above the column 501. The fixing buckle 502, fixedly connected to the top of the column 501, limits the rotation range of the rotating frame 503. When the rotating plate 407 rotates the rotating rod 408, the sliding column 409 slides on the fixed rod 504, causing the rotating frame 503 to oscillate periodically around the column 501. During this oscillation, the striking column 505 on one side of the rotating frame 503 strikes periodically. The filter plate 404 effectively removes impurities adhering to its surface, preventing excessive accumulation and clogging, and maintaining good air permeability. A through groove is provided at the bottom of the filter box 305, with an outlet 506 inside. Sealing plates 507 are fixedly connected to both sides of the outlet 506. A rotary knob 508 is located on the outside of the outlet 506, and a threaded rod 509 is installed inside. The threads on both sides of the threaded rod 509 are in opposite directions. Two sets of sealing plates 510 are threadedly connected to the top of the threaded rod 509. When impurities on the filter plate 404 are cleaned to the outlet 506, rotating the rotary knob 508 causes the threaded rod 509 to rotate.By moving the two sets of sealing plates 510 in opposite directions, the discharge port 506 can be opened, allowing impurities to be discharged from the discharge port 506.

[0025] During operation, adjusting the rotary knob 104 rotates the bevel gear 105, which in turn rotates the bevel gear 106, which in turn rotates the threaded rod 107. The rotation of the threaded rod 107 causes the sliding block 108 to move linearly above it. This allows the cleaning brush to clean the filter element 103 from the outside, and the cleaning scraper 201 to clean the inner wall of the separation chamber 101. This maintains the cleanliness of the filter element 103 and the separation chamber 101, preventing clogging of the filter element 103, maintaining the stability of the exhaust gas flow, and enabling efficient separation of exhaust gas. When cleaning the filter element 103 and the separation chamber 101, the suction pump 204 is started to allow the cleaning solution in the cleaning solution tank 205 to enter the spray head 203 through the first connecting pipe 202, and then spray it from the spray head 203 into the interior of the separation chamber 101, which can more thoroughly clean the oil stains on the inner wall of the separation chamber 101. After cleaning, the waste liquid is discharged through the discharge pipe. The motor 301 is started to rotate the rotating rod 302, which drives the rotating blades 303 to rotate. The high-speed rotation of the rotating blades 303 can accelerate the flow and mixing of waste gas in the separation chamber 101, enhance the centrifugal separation effect, and at the same time, during the cleaning process, the rotating blades... The airflow generated by plate 303 helps the cleaning fluid to be evenly distributed in the separation chamber 101, improving cleaning efficiency and effect. Starting motor 405 drives rotating rod 406 to rotate, which in turn drives rotating plate 407 to rotate. Rotating plate 407 then drives rotating rod 408 to rotate, which in turn drives sliding column 409 to move linearly above fixed rod 504. This linear movement of sliding column 409 allows rotating frame 503 to rotate around column 501 via a rotating connection point above column 501. The fixing buckle 502 fixedly connected to the top of column 501 limits the rotation range of rotating frame 503. When the rotating plate 407 drives the rotating rod 408 to rotate, the sliding column 409 slides on the fixed rod 504, which can push the rotating frame 503 to swing periodically around the column 501. During the swing of the rotating frame 503, the striking column 505 set on one side will regularly strike the filter plate 404, which can effectively remove impurities attached to the surface of the filter plate 404, prevent impurities from accumulating too much on the surface of the filter plate 404 and causing blockage, and maintain the good air permeability of the filter plate 404. By rotating the second rotating knob 508, the second threaded rod 509 is driven to rotate, causing the two sets of sealing plates 510 to move in opposite directions, thereby opening the discharge port 506 and allowing impurities at the discharge port 506 to be discharged.

[0026] Through the above steps, adjusting the rotary knob 104 drives the bevel gear 105 to rotate, which in turn drives the bevel gear 106 to rotate, which in turn drives the threaded rod 107 to rotate, and the threaded rod 107 to rotate, which in turn drives the sliding block 108 to move linearly above the threaded rod 107. This allows the cleaning brush to clean the filter element 103 from the outside, and the cleaning scraper 201 to clean the inner wall of the separation chamber 101. This maintains the cleanliness of the filter element 103 and the separation chamber 101, prevents the filter element 103 from becoming clogged, maintains the stability of the exhaust gas flow, and enables efficient separation of exhaust gas.
