Abstract
Description
Technical Field
[0001] This utility model belongs to the field of brake emission particulate separation technology, specifically relating to a brake emission particulate separation device. Background Technology
[0002] During traditional braking, the friction between brake pads and brake discs generates a large amount of particulate matter (PM10, PM2.5, and even nano-sized particles), which may contain heavy metals (such as copper, antimony, and iron) and carbides. Existing brake emission particulate separation devices can capture these particles, reducing air pollution. They also help reduce dust pollution around roads, lowering the risk to human health. For example, Chinese invention patent CN112969864B discloses a system for extracting brake particles while maintaining negative pressure. This system uses a negative pressure source connected to a suction nozzle to also extract dust-laden airflow near the brake disc, and a filter is installed in the middle of the pipeline to filter particulate matter. However, this split-type and long connecting pipeline structure is detrimental to cost control and underbody space management in automobiles. Utility Model Content
[0003] The technical problem solved by this utility model is to provide a brake emission particulate separation device that reduces costs, reduces piping, and reduces space occupation.
[0004] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0005] A brake emission particulate separation device includes a separation cylinder and an exhaust fan connected to the separation cylinder. The separation cylinder includes a cylinder body, a first filter assembly disposed within the cylinder body, and a cylinder cover covering the cylinder body. A receiving cavity is formed within the cylinder body. The first filter assembly is located within the receiving cavity. An inlet pipe communicating with the receiving cavity is provided on the cylinder body. The exhaust fan is disposed on the outer wall of the cylinder body and communicates with the receiving cavity.
[0006] Furthermore, the first filter assembly includes a first filter cartridge, the first filter cartridge including a first base, a first top seat corresponding to the first base, a first frame connected between the first base and the first top seat, and a first filter cloth sleeved on the first frame.
[0007] Furthermore, the first filter assembly also includes a second filter cartridge fitted inside the first filter cartridge. The second filter cartridge includes a second filter cotton sleeve, a second frame disposed inside the second filter cotton sleeve, and a second base connected to the second frame.
[0008] Furthermore, the first top seat is integrally connected to the cylinder cover.
[0009] Furthermore, the cylinder body is provided with limiting grooves corresponding to the first base and the second base.
[0010] Furthermore, a sealing ring is provided inside the limiting groove.
[0011] Furthermore, the exhaust fan includes an outer casing and a motor, a housing, and an impeller disposed within the outer casing. The housing is connected to the motor, and the impeller is disposed within the housing and connected to the motor. The housing has an air inlet and an air outlet, the air inlet being connected to the receiving cavity, and the outer casing has an exhaust hole.
[0012] Furthermore, the outer shell is integrally connected to the cylindrical body.
[0013] Beneficial effects: Compared with the prior art, the present invention has the following advantages:
[0014] 1. The exhaust fan is installed on the side wall of the separator, and the outer casing of the exhaust fan is integrally connected to the separator. No additional connecting pipes are required between the exhaust fan and the separator, which reduces costs and space requirements.
[0015] 2. The exhaust fan is arranged horizontally, and the fan heat dissipation can extend along the axis. It works with the centrifugal fan to form a three-dimensional air cooling system, and the operating temperature is 15-20℃ lower than the traditional layout. The L-shaped air duct design makes the airflow path longer but smoother. At the same time, it reduces the requirement for the longitudinal space at the top of the separator, making it suitable for the increasingly compact front compartment installation environment of electric vehicles.

[0026] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0027] like Figure 1 , Figure 2 and Figure 7 As shown, a brake emission particulate separation device includes a separation cylinder and a blower 9. The separation cylinder includes a cylinder body 1, a first filter assembly 2, and a cylinder cover 3. The cylinder body 1 is a hollow cylinder with an opening at the top. The cylinder cover 3 is placed on the cylinder body 1. In this embodiment, the upper side wall of the cylinder body 1 is provided with three first protrusions 131. The inner side wall of the cylinder cover 3 is provided with a first groove 311 corresponding to the first protrusions 131. When the cylinder cover 3 is placed on the cylinder body 1, the first protrusions 131 enter the first groove 311. When the cylinder cover 3 is rotated, the first protrusions 131 slide into the narrow opening of the first groove 311, restricting the axial movement of the cylinder cover 3, thereby connecting the cylinder cover 3 with the cylinder body 1. A receiving cavity 101 is formed inside the cylindrical body 1. An inlet pipe 11 is located at the middle of the lower end of the cylindrical body 1, and the inlet pipe 11 is connected to the receiving cavity 101. The dust-laden airflow enters the cylindrical body 1 through the inlet pipe 11. The first filter assembly 2 is located inside the cylindrical body 1. An exhaust fan 9 is installed on the outer wall of the cylindrical body 1 and is connected to the receiving cavity 101. When the exhaust fan 9 is working, it draws the air in the receiving cavity outward. After the dust-laden airflow entering through the inlet pipe 11 is filtered by the first filter assembly 2, the particles in the airflow remain in the cylindrical body 1, and the air is discharged from the exhaust fan 9. A bracket 19 is also connected to the outer wall of the cylindrical body 1. The bracket 19 is integrally connected to the cylindrical body 1 and has mounting holes to facilitate the connection of the cylindrical body 1 to other equipment.
[0028] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the exhaust fan 9 can be an existing small centrifugal fan. The exhaust fan 9 includes an outer casing 91, a motor 92, a housing 93, and an impeller 94. The outer casing 91 is trumpet-shaped and is integrally connected to the cylinder 1. In this embodiment, both the outer casing 91 and the cylinder 1 are made of polymer material and are integrally injection molded. The motor 92, housing 93, and impeller 94 are all disposed inside the outer casing 91. The outer casing 91 has a groove corresponding to the shape of the housing 93 to restrict the position of the housing 93. The motor 92, housing 93, and impeller 94 are integrally connected and detachably connected to the outer casing 91 by connecting bolts. The outer wall of the housing 93 is connected to the motor 92. 2. The outer wall is connected. The impeller 94 is installed inside the housing 93 and connected to the output shaft of the motor 92. The housing 93 has an air inlet 931 and an air outlet 932. The air inlet 931 is located at the center of the housing 93 and communicates with the receiving cavity 101. The air outlet 932 is located on the side wall of the housing 93. The motor 92 is connected to an external power source via a power cord. When the motor 92 is working, it drives the impeller 94 to rotate. Airflow is drawn into the housing 93 from the air inlet 931 and discharged from the air outlet 932. The outer housing 91 has multiple exhaust holes 911. The airflow discharged from the air outlet 932 is discharged from the exhaust holes 911. When the exhaust fan 9 is working, it generates a negative pressure in the receiving cavity 101, thereby drawing dust-laden gas into the cylinder 1 from the inlet pipe 11.
[0029] like Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, the first filter assembly 2 includes a first filter cartridge 21 and a second filter cartridge 22. The first filter cartridge 21 includes a first base 211, a first top seat 212, a first frame 213, and a first filter cloth 214. The first base 211 is annular, and the first top seat 212 is also annular, corresponding to the first base 211. The first frame 213 connects the first base 211 and the first top seat 212. The first frame 213 includes multiple first ribs arranged in a circular array, and the first frame 213 has a hollow center. In this area, the first filter cloth 214 uses existing pleated composite filter material, which is a non-woven fabric made of polyester fiber or other materials folded into a pleated structure. The first filter cloth 214 is sleeved on the outside of the first frame 213. The first base 211 and the first top seat 212 are both provided with receiving grooves corresponding to the first filter cloth 214. The upper end of the first filter cloth 214 enters the receiving groove of the first top seat 212, and the lower end of the first filter cloth 214 enters the receiving groove of the first base 211. The first base 211 and the first top seat 212 protect and limit the first filter cloth 214. The first top seat 212 is integrally connected to the cylinder cover 3, so that the first filter cylinder 21 can be taken out from the cylinder body 1 when the cylinder cover 3 is removed. The second filter cartridge 22 is fitted inside the first filter cartridge 21. The second filter cartridge 22 includes a second filter cotton sleeve 221, a second frame 222, and a second base 223. The second base 223 is annular and its diameter is smaller than the inner diameter of the first base 211. The lower end of the second frame 222 is connected to the second base 223. The second frame 222 includes multiple second ribs arranged in a circular array. The second filter cotton sleeve 221 is fitted outside the second frame 222. The second filter cotton sleeve 221 uses existing filter cotton, and the pore size of the second filter cotton sleeve 221 is larger than that of the first filter cartridge 21. The filter cloth 214 has a filter pore size. The outer circumferential side wall of the second base 223 is provided with four limiting grooves 2232. The first base 211 is provided with limiting protrusions 2112 corresponding to the limiting grooves 2232. When in use, the second filter cartridge 22 is inserted into the center of the first filter cartridge 21. The limiting protrusions 2112 of the first base 211 enter the limiting grooves 2232 on the second base 223. The first base 211 and the second base 223 are engaged, so that the second filter cartridge 22 is connected to the first filter cartridge 21. When the cover 3 is removed, the first filter assembly 2 is taken out as a whole. The cylinder 1 is provided with a limiting groove 12. The diameter of the limiting groove 12 corresponds to the outer diameter of the first base 211, so that the limiting groove 12 can limit the position of the first filter component 2. The limiting groove 12 is provided with a sealing ring 121, which is made of rubber. The first base 211 is provided with a first protruding ring 2111, and the second base 223 is provided with a second protruding ring 2231. When the cylinder cover 3 is connected to the cylinder 1, the first protruding ring 2111 and the second protruding ring 2231 press on the sealing ring 121 to play a sealing role, ensuring that the dust-laden airflow entering the inlet pipe 11 enters from the center of the second base 223. The dust-laden airflow entering the second filter cylinder 22 is filtered by the second filter cotton sleeve 221, and then filtered by the first filter cloth 214 before entering the exhaust fan 9.
