DETAILED DESCRIPTION
[0024] See also Figure 1-Figure 8 A vehicle exhaust pipe, comprising a flange pipe 1, the right side of the flange pipe 1 is connected with a purification shell 2, the left and right sides of the top of the purification shell 2 are provided with mounting grooves 8, the inner cavity of the mounting groove 8 is provided with a purification component 4, a clamping component 3 is rotatably installed at the center of the top of the purification shell 2, the right side of the purification shell 2 is connected with an exhaust main pipe 5, the right side of the inner cavity of the exhaust main pipe 5 is fixedly installed with an anti-backflow component 6, and the center of the right side of the exhaust main pipe 5 is connected with an exhaust tail pipe 7;
[0025] See also Figure 4 The purification component 4 includes a fixed frame 41, which penetrates the inner cavity of the installation groove 8. The inner cavities of the two fixed frames 41 from left to right are respectively fixed with a primary filter 42 and a fine filter 43. The top of the fixed frame 41 is fixedly welded with a mounting plate 44. By setting the mounting plate 44, it is convenient for the user to take the fixed frame 41 out of the purification shell 2, and it is also convenient to install the fixed frame 41 so that it can be fixed in the installation groove 8. The opposite sides of the bottom of the mounting plate 44 are provided with a snap-in groove 45;
[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8 The clamping assembly 3 includes a rotating column 31, which is rotatably connected to the center of the top through a rotating shaft. A cross clamping plate 32 is provided on the top fixed sleeve of the surface of the rotating column 31. A knob is provided on the top of the rotating column 31, which can facilitate the staff to rotate the rotating column 31 and improve the convenience during operation;
[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8 The front and rear sides of the top of the cross clamp 32 are threadedly connected with fastening bolts 33, and the bottom of the fastening bolts 33 penetrates the cross clamp 32 and is threadedly connected to the top of the purification shell 2;
[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The backflow prevention component 6 includes a backflow prevention bucket 61, which is fixedly installed on the right side of the inner cavity of the exhaust pipe 5. An exhaust auxiliary hole 62 is opened through the top of the right side of the backflow prevention bucket 61. The exhaust auxiliary hole 62 is used to assist the exhaust gas to be discharged, so as to avoid excessive pressure caused by the increase of gas in the exhaust pipe 5 and increase the exhaust gas discharge speed. The center of the left side of the bottom of the backflow prevention bucket 61 is connected to a drain pipe 63;
[0029] The bottom of the drain pipe 63 passes through the bottom of the exhaust main pipe 5. A one-way valve 64 is fixedly installed on the surface of the drain pipe 63 at one end of the bottom of the exhaust main pipe 5. The oil and water in the exhaust gas discharge process or part of the moisture entering from the outside can be discharged from the drain pipe 63 by opening the one-way valve 64, so as to avoid sewage remaining in the exhaust main pipe 5 and affecting the exhaust effect. The backflow prevention bucket 61 is a funnel-shaped structure. The funnel shape can effectively avoid the exhaust gas diversion, so that the exhaust gas will not flow back into the pipe after being discharged, thereby improving the exhaust gas emission efficiency, and the left end side opening of the anti-backflow bucket 61 is larger than the right side opening.
[0030] When in use, the flange pipe 1 is connected to the position of the automobile exhaust emission system. After the gas is discharged, it enters the purification shell 2 through the flange pipe 1, and is filtered through the primary filter 42 and the fine filter 43. The gas discharged after filtering some impurities and harmful substances in the exhaust gas enters the exhaust main pipe 5, passes through the anti-backflow bucket 61, and is discharged from the exhaust tail pipe 7. The exhaust gas is assisted to be discharged through the exhaust auxiliary hole 62 to avoid excessive pressure caused by the increase of gas in the exhaust main pipe 5. The oil and water in the exhaust gas discharge process or part of the moisture entering from the outside can be discharged from the drain pipe 63 by opening the one-way valve 64. When it is necessary to disassemble and replace the purification component 4, the fastening bolt 33 is unscrewed, and then the rotating column 31 is rotated counterclockwise to drive the cross clamping plate 32 to move out from the inside of the clamping groove 45, so that the purification component 4 can be taken out upward for disassembly and replacement.
[0031] To sum up: the vehicle exhaust pipe, through the cooperation of the flange pipe 1, the purification shell 2, the clamping assembly 3, the purification assembly 4, the exhaust main pipe 5 and the anti-backflow assembly 6, solves the problem that it is inconvenient to filter and purify the exhaust gas, and the exhaust gas may enter the pipe from the outside in rainy weather.
