Description

Technical Field

[0001] This application relates to the field of catalytic mufflers, and more specifically, to a U-shaped catalytic muffler component suitable for tractors. Background Technology

[0002] Catalytic converter components refer to devices installed in the diesel engine exhaust system to reduce particulate matter in the exhaust. They consist of DOC, DPF, and SCR / ASC devices. The intake port is located on the DOC, and the exhaust port is located on the SCR / ASC device. Its main function is to reduce carbon monoxide, hydrocarbons, particulate matter, and nitrogen oxides in the emissions, and it also has a noise reduction function.

[0003] The existing tractor is equipped with a linear catalytic converter muffler component, which consists of DOC, DPF and SCR / ASC devices from bottom to top. This results in a relatively high overall height of the muffler. Sometimes it is installed on the right front of the cab, which can easily obstruct the driver's view. Moreover, the overall height makes it look rather obtrusive and not aesthetically pleasing. Summary of the Invention

[0004] To overcome the shortcomings of the existing system, this application provides a U-shaped catalytic muffler component suitable for tractors. This component solves the problem that the existing linear catalytic muffler components on tractors, which consist of DOC, DPF and SCR / ASC devices from bottom to top, result in a relatively high overall height of the muffler. Sometimes, when installed on the right front of the cab, this can easily obstruct the driver's view, and the overall height makes it look rather abrupt and unsightly.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A U-shaped catalytic converter component suitable for tractors includes a treatment component and a protection component.

[0007] The processing component includes a base, a transition shell, a DPF unit, a DOC unit, an SCR unit, and an ASC unit. The transition shell is mounted on the top of the base. The DPF unit is connected to one end of the transition shell. The DOC unit is connected to the top of the DPF unit. The SCR unit is connected to the other end of the transition shell. The ASC unit is connected to the top of the SCR unit.

[0008] The protective assembly includes a first heat shield and a second heat shield. The first heat shield is installed on the top of the base, and the second heat shield is installed on the top of the base, with the first heat shield and the second heat shield facing each other.

[0009] In one specific implementation, an air intake pipe is connected to the top of the DOC unit, and a support plate is provided on the outer wall of the DOC unit and abuts against the air intake pipe.

[0010] In the above implementation process, an intake pipe is set up to connect to the exhaust pipe of the diesel engine, so that the engine exhaust gas is introduced into the DOC unit.

[0011] In one specific implementation, a mounting plate is provided on the top of the base, and multiple tube bundles are fixedly mounted on the mounting plate.

[0012] In the above implementation process, a mounting plate is set up for the installation and fixation of the tube bundles of each processing unit, serving as a fulcrum for stable installation of the tube bundles.

[0013] In one specific implementation, the base end is provided with a vertical plate, and both the first heat insulation cover and the second heat insulation cover are bolted to the vertical plate.

[0014] In the above implementation process, a vertical plate is set up to connect the first heat insulation cover and the second heat insulation cover and fix them to the vertical plate with bolts, thereby protecting the whole structure.

[0015] In one specific implementation, the connecting pipe and the transition bottom shell are connected by a first clamp, and the SCR unit and the transition bottom shell are also connected by the first clamp.

[0016] In the above implementation process, a first clamp is set to reinforce the various units on the connecting transition shell and ensure the connection is firm.

[0017] In one specific implementation, the DPF unit and the DOC unit are connected by a second clamp.

[0018] In one specific implementation, both the first heat insulation cover and the second heat insulation cover are provided with heat dissipation vents, and inclined baffles are provided inside the heat dissipation vents.

[0019] In the above implementation process, heat dissipation vents are opened to connect the interior and the outside world, ensuring ventilation and heat dissipation, while the inclined baffle can block most water droplets or debris from entering.

[0020] In one specific implementation, the ASC unit is provided with a connecting pipe at the top, and the connecting pipe is connected to a silencer exhaust pipe.

[0021] In the above implementation process, a connecting pipe is set up for installing and connecting the silencer exhaust pipe, and the side is connected with bolts for easy disassembly and assembly.

[0022] The advantages of this embodiment are: by setting a base, a transition shell, a DPF unit, a DOC unit, an SCR unit, and an ASC unit, and by connecting the DPF unit and the DOC unit at one end of the transition shell at the bottom, and connecting the SCR unit and the ASC unit at the other end of the transition shell, the engine exhaust gas can be treated and silenced. At the same time, the overall U-shaped structure not only reduces the height but also makes it more aesthetically pleasing. Combined with the first and second heat shields for protection, it effectively avoids the situation where the traditional straight-line processor is too tall and obstructs the driver's view.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments.

[0030] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0031] In the embodiments, unless otherwise specified, all methods used are conventional methods in the art.

[0032] Please see Figures 1-5 This application provides a U-shaped catalytic converter component suitable for tractors, including a treatment component 100 and a protection component 200.

[0033] Please see Figure 1 , 2 3 and 4, the processing component 100 includes a base 110, a transition shell 120, a DPF unit 130, a DOC unit 140, an SCR unit 150, and an ASC unit 160. The transition shell 120 is mounted on top of the base 110. The DPF unit 130 is connected to one end of the transition shell 120. The DOC unit 140 is connected to the top of the DPF unit 130. The SCR unit 150 is connected to the other end of the transition shell 120. The ASC unit 160 is connected to the top of the SCR unit 150.

[0034] It should be noted that the DPF unit 130 is a particulate filter, the DOC unit 140 is a diesel oxidation catalyst, the SCR unit 150 is a selective catalytic reduction device, and the ASC unit 160 is an ammonia oxidation catalyst. Their specific principles and connection methods are existing technologies well known to those skilled in the art, and will not be elaborated on here.

[0035] The DOC unit 140 has an intake pipe 141 connected to its top. The outer wall of the DOC unit 140 has a support plate that abuts against the intake pipe 141. The intake pipe 141 is used to connect to the exhaust pipe of the diesel engine and to introduce the engine exhaust gas into the DOC unit 140.

[0036] Specifically, a mounting plate 170 is provided on the top of the base 110. Multiple tube bundles 180 are fixedly mounted on the mounting plate 170. By setting the mounting plate 170, the tube bundles 180 of each processing unit are installed and fixed, and the tube bundles 180 are installed stably as a fulcrum.

[0037] In this embodiment, the connecting pipe 161 and the transition bottom shell 120 are connected by the first clamp 121, and the SCR unit 150 and the transition bottom shell 120 are also connected by the first clamp 121. By setting the first clamp 121, the various units on the transition bottom shell 120 are reinforced to ensure the connection is firm. The DPF unit 130 and the DOC unit 140 are connected by the second clamp 142.

[0038] In one specific implementation, the top of the ASC unit 160 is provided with a connecting pipe 161, and the connecting pipe 161 is connected to a silencer exhaust pipe 190. The connecting pipe 161 is used to install and connect the silencer exhaust pipe 190, and the side is connected with bolts for easy disassembly and assembly.

[0039] Please see Figure 1 , 25. The protective component 200 includes a first heat shield 210 and a second heat shield 220. The first heat shield 210 is mounted on the top of the base 110, and the second heat shield 220 is mounted on the top of the base 110, with the first heat shield 210 and the second heat shield 220 facing each other.

[0040] The base 110 has a vertical plate 112 at its end. The first heat insulation cover 210 and the second heat insulation cover 220 are both installed on the vertical plate 112 by bolts. The vertical plate 112 is used to connect the first heat insulation cover 210 and the second heat insulation cover 220 and fix them to the vertical plate 112 by bolts, thereby protecting the whole structure.

[0041] In this embodiment, both the first heat insulation cover 210 and the second heat insulation cover 220 are provided with heat dissipation vents 230, and an inclined baffle is provided inside the heat dissipation vent 230. By opening the heat dissipation vent 230, the interior and the outside can be connected to ensure ventilation and heat dissipation. The inclined baffle can block most water droplets or debris from entering.

[0042] The working principle of this U-shaped catalytic muffler component for tractors is as follows: During use, the engine exhaust pipe is connected to the intake pipe 141. The exhaust gas first enters the diesel oxidation catalyst (DOC) unit 140 for initial treatment, then enters the lower particulate filter (DPF) unit 130 for further treatment, and then enters the transition bottom shell 120. Through the cavity of the bottom transition bottom shell 120, it enters the selective catalytic reduction (SCR) unit 150 and the ammonia oxidation catalyst (ASC) unit 160 for further treatment. Finally, the gas is discharged from the muffler exhaust pipe 190. The transition bottom shell 120, DPF unit 130, DOC unit 140, SCR unit 150, and ASC unit 160 form a U-shaped treatment structure, which not only reduces the overall height but also makes the installation more aesthetically pleasing and practical, avoiding the problem of traditional straight-line designs easily obstructing the view.

[0043] It should be noted that the specific model specifications of DPF unit 130, DOC unit 140, SCR unit 150 and ASC unit 160 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0044] The power supply and principles of DPF unit 130, DOC unit 140, SCR unit 150 and ASC unit 160 are clear to those skilled in the art and will not be described in detail here.

[0045] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
