Description

[0002] Environmental issues are increasingly attracting the attention of the whole society. Among environmental issues, air pollution is an important component, and automobile exhaust is one of the major sources of air pollution. When a car climbs a slope at low speed, the engine temperature of the car will rise, causing the exhaust temperature of the car to rise. The unsaturated olefins and gums in the fuel will produce a charred substance under high temperature conditions, that is, carbon deposits formed by automobile exhaust. After a period of time, if the carbon deposits are not cleaned, it is very easy to cause blockage of the exhaust pipe and affect the normal exhaust function of the exhaust pipe. The way people clean carbon deposits in life is generally to go to 4S shops to buy some special cleaning agents for manual cleaning. This not only consumes a lot of money, but also requires manual removal, cleaning and reinstallation of automobile parts, wasting a lot of time and energy.

[0049] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] like Figure 1 and Figure 2As shown, the present invention provides:

[0051] A device for preventing carbon deposits in automobile exhaust comprises a treatment tube assembly 1, an electrostatic generating assembly 2 and a scraping assembly 3. The treatment tube assembly 1 is connected to the exhaust pipeline. The treatment tube assembly 1 has an electrostatic adsorption chamber. The electrostatic generating assembly 2 is arranged on the outside of the treatment tube assembly 1. The scraping assembly 3 is arranged on the inner wall of the electrostatic adsorption chamber. In the working state, the scraping assembly 3 scrapes the inner wall of the electrostatic adsorption chamber and discharges the scraped material out of the treatment tube assembly 1.

[0052] Both ends of the treatment cylinder assembly 1 are open. The treatment cylinder assembly 1 is arranged upstream of the three-way catalytic converter to remove solid particulate matter in the exhaust gas in advance, thereby preventing the solid particulate matter in the exhaust gas from clogging the three-way catalytic converter.

[0053] When the exhaust gas flows from one end of the treatment tube to the other end, the electrostatic generating component 2 generates static electricity on the outside of the treatment tube component 1, thereby forming an electrostatic adsorption chamber in the inner cavity of the treatment tube component 1. The solid particles in the exhaust gas are adsorbed on the inner wall of the electrostatic adsorption chamber under the action of static electricity, and the exhaust gas with solid particles removed passes through the treatment tube component 1 and then enters the three-way catalytic converter for further treatment. When the solid particles accumulate on the inner wall of the electrostatic adsorption chamber, the scraping component 3 scrapes off the solid particles attached to the inner wall of the electrostatic adsorption chamber, thereby completing the cleaning of the inner wall of the electrostatic adsorption chamber and preventing the inner wall of the electrostatic adsorption chamber from being unable to adsorb the solid particles in the exhaust gas due to excessive carbon deposits.

[0054] In this embodiment, the electrostatic generating component 2 is arranged on the outside of the treatment barrel component 1, and the scraping component 3 is arranged on the inner wall of the treatment barrel component 1, so that the treatment barrel component 1 forms an electrostatic adsorption chamber, so that the solid particles in the exhaust gas are adsorbed on the inner wall of the treatment barrel component 1, and the scraping component 3 can scrape the attached solid particles out of the treatment barrel component 1, thereby ensuring that the solid particles in the exhaust gas cannot be blocked in the three-way catalytic converter.

[0055] like Figure 3 As shown, the processing cylinder assembly 1 includes an inner cylinder 11, a first outer cylinder 12, a second outer cylinder 13 and a sealing member 14. The first outer cylinder 12 is coaxially arranged on the outside of the inner cylinder 11, and the inner diameter of the first outer cylinder 12 is larger than the outer diameter of the inner cylinder 11; the second outer cylinder 13 is coaxially arranged on the outer end of the first outer cylinder 12, the electrostatic generating assembly 2 is arranged on the outer wall of the second outer cylinder 13, and the inner cavity of the second outer cylinder 13 forms an electrostatic adsorption cavity. The scraping wall assembly 3 is arranged on the inner walls of the first outer cylinder 12 and the second outer cylinder 13, and the sealing member 14 is arranged outside the inner cavity and sealed at the other port of the first outer cylinder 12.

[0056] By coaxially arranging the first outer cylinder 12 on the outside of the inner cylinder 11, an annular cavity is formed between the inner circumferential surface of the first outer cylinder 12 and the outer circumferential surface of the inner cylinder 11, and the electrostatic generating component 2 is arranged on the outside of the second outer cylinder 13. When exhaust gas passes through one end of the second outer cylinder 13 from one end of the second outer cylinder 13, the electrostatic generating component 2 generates static electricity in the second outer cylinder 13, and then an electrostatic adsorption cavity is formed in the inner cavity of the second outer cylinder 13, so that the solid particles in the exhaust gas passing through the second outer cylinder 13 will be adsorbed on the inner wall of the second outer cylinder 13, and at the same time, the scraping component 3 can scrape the inner wall of the second outer cylinder 13, so that the attached solid particles fall into the annular cavity, and at the same time, the solid particles break through the constraints of the sealing member 14 and leave the first outer cylinder 12.

[0057] like Figure 3 and Figure 8 As shown, the sealing member 14 includes a sealing ring 141, a connecting rod 142 and a spring 143. The sealing ring 141 is coaxially slidably arranged on the inner cavity. The sealing ring 141 has a conical surface that can abut against the end of the first outer cylinder 12. The connecting rod 142 connects the first outer cylinder 12 and the inner cylinder 11 along the axis. The outer end of the sealing ring 141 is provided with a ring member coaxial therewith. The connecting rod 142 passes through the ring member and slides with it. The spring 143 is sleeved on the connecting rod 142 so that the sealing ring 141 elastically abuts against one end of the first outer cylinder 12.

[0058] After the scraper assembly 3 scrapes off the solid particles on the inner wall of the second outer cylinder 13, the solid particles slide on the inner walls of the second outer cylinder 13 and the first outer cylinder 12 under the action of the scraper assembly 3 until the solid particles gather at the inner end of the sealing ring 141. The first outer cylinder 12 and the inner cylinder 11 are fixedly connected by a connecting rod 142 to form a stable exhaust gas treatment structure. When the force of the scraper assembly 3 on the solid particles is greater than the elastic force of the spring 143, the sealing ring 141 overcomes the elastic force of the spring 143 and slides on the connecting rod 142. At the same time, the solid particles at the inner end of the sealing ring 141 overflow from the opened port of the first outer cylinder 12, thereby preventing the solid particles from being blocked in the annular cavity.

[0059] like Figure 4 、 Figure 5 and Figure 6As shown, the electrostatic generating assembly 2 includes a rotating ring 21, a guide blade 22 and a fur strip 23. The rotating ring 21 is coaxially rotatably arranged at one end of the second outer cylinder 13. One end of the rotating ring 21 is provided with a clamping strip 211 extending along its axial direction. The clamping strip 211 is circumferentially distributed on the circumferential surface of the second outer cylinder 13; the guide blade 22 is axially arranged on the inner periphery of the rotating ring 21 and extends into the inner cylinder 11; the fur strip 23 is clamped on the clamping strip 211 along the axial direction of the rotating ring 21, and the fur strip 23 abuts against the outer circumferential surface of the second outer cylinder 13. The second outer cylinder 13 is made of electrostatic material.

[0060] When the exhaust gas containing solid particulate matter passes through one end of the first outer cylinder 12 from one end of the second outer cylinder 13, the rotating ring 21 is rotatably arranged at one end of the second cylinder, and the guide vane 22 is arranged at one end of the rotating ring 21. The exhaust gas acts on the guide vane 22 during the flow, so that the guide vane 22 drives the rotating ring 21 to rotate at one end of the second outer cylinder 13. At the same time, the rotating ring 21 drives the clamping strip 211 to rotate outside the second outer cylinder 13, and the fur strip 23 is clamped on the clamping strip 211, so that during the rotation of the clamping strip 211, the fur strip 23 rubs against the outer circumferential surface of the second outer cylinder 13. Since the second outer cylinder 13 is made of electrostatic material, the inner cavity of the second outer cylinder 13 forms an electrostatic adsorption cavity, thereby adsorbing solid particulate matter in the exhaust gas.

[0061] like Figure 6 As shown, the scraping assembly 3 includes a first fixed ring 31 and a spiral blade 32. The first fixed ring 31 is coaxially fixedly arranged at one end of the rotating ring 21, and the spiral blade 32 is coaxially arranged at one end of the first fixed ring 31. The outer edge of the spiral blade 32 abuts against the inner wall of the first outer cylinder 12 and the second outer cylinder 13.

[0062] An annular cavity is formed between the outer circumferential surface of the inner cylinder 11 and the inner circumferential surface of the first outer cylinder 12 .

[0063] When the flowing exhaust gas drives the rotating ring 21 to rotate at the end of the second outer cylinder 13, since the first fixed ring 31 is fixedly set at one end of the rotating ring 21, the rotating ring 21 drives the first fixed ring 31 to rotate at the end of the second outer cylinder 13, and at the same time the spiral blade 32 rotates on the inner walls of the first outer cylinder 12 and the second outer cylinder 13. The rotating spiral blade 32 can scrape off the solid particles attached to the inner wall of the second outer cylinder 13, and the spiral blade 32 continues to rotate to scrape the solid particles into the annular cavity. The solid particles gather at the inner end of the sealing ring 141 until the force of the rotating spiral blade 32 on the accumulated solid particles is greater than the elastic force of the spring 143. The sealing ring 141 overcomes the elastic force and opens one end of the annular cavity, so that the solid particles can overflow from the annular cavity.

[0064] like Figure 6 As shown, the wall scraping assembly 3 further includes a support rod 33 , which is arranged at one end of the first fixing ring 31 along the axial direction of the first fixing ring 31 , and passes through the spiral blade 32 and is fixedly connected thereto.

[0065] By passing the support rod 33 through the spiral blade 32 and fixing it to the first fixing ring 31 , the spacing of the spiral blade 32 cannot change due to rotation, and the spiral blade 32 can further stably scrape and feed materials in the first outer cylinder 12 and the second outer cylinder 13 .

[0066] like Figure 7 As shown, a first connecting groove 121 is provided at one end of the first outer cylinder 12, and a second connecting groove 131 is provided at one end of the second outer cylinder 13. The processing cylinder assembly 1 also includes a connecting ring 15, which is coaxially arranged between the first outer cylinder 12 and the second outer cylinder 13. The two ends of the connecting ring 15 are fixedly connected to the first connecting groove 121 and the second connecting groove 131 respectively.

[0067] In order to ensure a stable connection between the first outer cylinder 12 and the second outer cylinder 13, a first connecting groove 121 coaxial with the second outer cylinder 13 is opened at one end of the first outer cylinder 12 facing the second outer cylinder 13, and a second connecting groove 131 coaxial with the second outer cylinder 13 is opened at one end of the second outer cylinder 13 facing the first outer cylinder 12. A connecting ring 15 is arranged at the opposite ends of the first outer cylinder 12 and the second outer cylinder 13. At the same time, after the two ends of the connecting ring 15 are respectively engaged with the first connecting groove 121 and the second connecting groove 131, they are fixedly connected to the first outer cylinder 12 and the second outer cylinder 13 by bolts extending radially along the connecting ring 15.

[0068] like Figure 3 As shown, the treatment cylinder assembly 1 also includes a closed cylinder 16, one end of which is provided with a second fixed ring 161, and the outer end of the second fixed ring 161 is provided with an end pipe 162 connected to the exhaust pipe, the closed cylinder 16 is coaxially arranged on the outside of the second outer cylinder 13, one end of the closed cylinder 16 is sealed and connected to the connecting part of the first outer cylinder 12 and the second outer cylinder 13, the clamping strip 211 extends axially to between the inner circumferential surface of the closed cylinder 16 and the outer circumferential surface of the second outer cylinder 13, and the rotating ring 21 is coaxially rotatably arranged at the inner end of the second fixed ring 161.

[0069] By setting the closed cylinder 16 outside the second outer cylinder 13, a closed cavity with one end open is formed between the inner circumferential surface of the closed cylinder 16 and the outer circumferential surface of the second outer cylinder 13, and the rotating ring 21 is rotatably set at the inner end of the second fixed ring 161, and the clamping strip 211 extends into the closed ring along the axis, so that when the rotating ring 21 rotates, the clamping strip 211 can rotate in the closed ring, and then the fur strip 23 can rotate in the closed ring. While preventing the fur strip 23 from being exposed and corroded, the rotating ring 21 can rotate stably at the inner end of the second fixed ring 161, and the end pipe 162 set at the outer end of the second fixed ring 161 can be connected to the exhaust pipeline to facilitate the input of exhaust gas for further treatment.

[0070] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
