Specific embodiments

[0025] This specific embodiment is a treatment device for tail gas, and its structural schematic diagram is as Figures 1 - 7 shown, including an automobile exhaust pipe body 11 and a mounting pipe 1. The mounting pipe 1 is sleeved on the side wall of the automobile exhaust pipe body 11. A uniformly distributed fixing plate 2 is fixedly connected to the outer wall of the mounting pipe 1 near the left side. The fixing plate 2 is arranged in a U shape. An arc-shaped rod 3 is movably connected between the inner walls on both sides of the fixing plate 2. A U-shaped plate 4 is movably connected between the front and rear side walls of the arc-shaped rod 3 near the left side. A clamping plate 5 is fixedly connected to the side of the U-shaped plate 4 opposite to the automobile exhaust pipe body 11. The clamping plate 5 is in contact with the automobile exhaust pipe body 11. A fixing mechanism is arranged on the side wall of the mounting pipe 1. A filter tube 12 is fixedly connected to the right side wall of the automobile exhaust pipe body 11. The right side wall of the filter tube 12 is closed. A filtering mechanism is arranged inside the filter tube 12.

[0026] The exhaust pipe body 11 in this technical solution is a common exhaust pipe on the market. The clamping plate 5 is made of stainless steel, and stainless steel has the functions of high temperature resistance and corrosion prevention, so that it will not loosen even when subjected to the high temperature of the exhaust pipe body 11.

[0027] As Figure 2 and Figure 3 shown, the fixing mechanism includes a conical ring 8. The conical ring 8 is sleeved on the outer wall of the mounting pipe 1. An external thread groove 10 is opened on the outer wall of the mounting pipe 1. An internal thread ring 9 is sleeved on the outer wall of the mounting pipe 1. The internal thread ring 9 is slidably connected between the conical ring 8. The internal thread ring 9 is matched with the external thread groove 10. Uniformly distributed round holes 18 are opened on the outer wall of the internal thread ring 9.

[0028] The fixed mechanism enables multiple arc-shaped rods 3 to swing towards the middle simultaneously, and multiple clamping plates 5 can hold the exhaust pipe body 11 at the same time. In this way, the installation pipe 1 can be fixed on the exhaust pipe body 11 that needs to be used. The multiple clamping plates 5 can evenly clamp the exhaust pipe body 11, which can prevent the exhaust pipe body 11 from being damaged.

[0029] As Figures 3 - 7 shown, the filtering mechanism includes a placement pipe 13. The right side wall of the placement pipe 13 is closed. The placement pipe 13 is arranged inside the filtering pipe 12. A filter 14 is assembled inside the placement pipe 13. The right side wall of the placement pipe 13 is provided with evenly distributed first exhaust openings 15, and the right side wall of the filtering pipe 12 is provided with evenly distributed second exhaust openings 16.

[0030] The filter 14 in this technical solution is a common high-temperature resistant filter on the market. Its internal structure is made of steel wire, which can be cleaned and reused. During filtration, carbon particles will adhere to the inside of the filter 14 to play a filtering role.

[0031] As Figures 1 - 7 shown, a spring 17 is fixedly connected between the right inner wall of the placement pipe 13 and the filtering pipe 12. The outer wall of the filtering pipe 12 is provided with evenly distributed pressure relief holes 19 near the left side. The outer wall of the placement pipe 13 is provided with a sealing groove 20 near the left side. A sealing ring 21 is assembled in the sealing groove 20, and the outer wall of the sealing ring 21 is in contact with the inner wall of the filtering pipe 12.

[0032] Through the pressure relief holes 19, when the air pressure inside the exhaust pipe body 11 and the installation pipe 1 is relatively high, as the pressure increases, it will gradually push the placement pipe 13 to move to the right, causing the pressure relief holes 19 to open. At the same time, the air pressure inside the installation pipe 1 is discharged, which can play a good role in protecting the vehicle and avoid the internal pressure of the installation pipe 1 increasing due to the blockage of the filter 14 during long-term use.

[0033] Among them, one end of the fixed plate 2 is provided with a rectangular opening 6. A pulley 7 is movably connected between the inner walls on both sides of the rectangular opening 6. The pulley 7 is in contact with the inclined surface of the conical ring 8. By means of the pulley 7, the resistance and friction can be reduced, so that it is more labor-saving to rotate the internal thread ring 9, and the service life can be extended. At the same time, the clamping plates 5 hold the exhaust pipe body 11 more evenly.

[0034] In addition, one side of the internal thread ring 9 is fixedly connected with an annular slider. One side of the conical ring 8 is provided with an annular chute matching the annular slider. Through the annular slider and the annular chute, the internal thread ring 9 can drive the conical ring 8 to move left or right when rotating, and the conical ring 8 can also move left or right without rotating.

[0035] Working principle: When this technical solution is in use, first, the filter 14 is assembled and placed inside the placement tube 13. Next, the installation tube 1 is sleeved on the automobile exhaust pipe body 11, and a rod-shaped tool is inserted into the round hole 18 to rotate the internal thread ring 9 clockwise, causing the internal thread ring 9 to push the conical ring 8 to the left, so that the pulley 7 slides upward on the inclined surface of the conical ring 8, thereby causing multiple arc-shaped rods 3 to swing towards the middle simultaneously. In this way, multiple clamping plates 5 will hold the automobile exhaust pipe body 11 at the same time, enabling the installation tube 1 to be fixed on the automobile exhaust pipe body 11, and then it can be used normally. When the vehicle starts, because the temperature of the three-way catalytic converter is not high and the fuel combustion is not sufficient at the moment of startup, black smoke will appear in the vehicle. At this time, the black smoke will enter the filter tube 12 through the automobile exhaust pipe body 11 after passing through the three-way catalytic converter, and the filter 14 will filter the black smoke. The filtered exhaust gas will be discharged through the first exhaust opening 15 and the second exhaust opening 16, and the carbon particles filtered out will remain in the placement tube 13. In addition, if the vehicle is traveling at high speed and the pressure inside the automobile exhaust pipe body 11 and the installation tube 1 is relatively high, the pressure will impact the filter 14, causing the filter 14 and the placement tube 13 to move to the right and compress the spring 17, so that the pressure relief hole 19 is connected to the inside of the filter tube 12. In this way, the air pressure inside the filter tube 12 and the installation tube 1 will be instantly discharged through the pressure relief hole 19. After the air pressure is discharged, the placement tube 13 and the filter 14 will be pushed to the left by the elastic force of the spring 17, and the outer wall of the placement tube 13 will block the pressure relief hole 19. This can protect the vehicle and the installation tube 1 and effectively improve the safety and stability of its use. When the filter 14 has been used for a period of time, it can be replaced or cleaned. First, a rod-shaped tool needs to be inserted into the round hole 18, and the internal thread ring 9 is rotated counterclockwise through the tool, causing the internal thread ring 9 to drive the conical ring 8 to move to the right. In this way, the inclined surface of the conical ring 8 is separated from the pulley 7 on the arc-shaped rod 3, and multiple clamping plates 5 will also become loose. Next, the installation tube 1 can be removed, and the filter 14 can be taken out for replacement or cleaning, effectively improving the convenience of its use.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of this technical solution is within the protection scope of the present invention.
