Detailed Description
The invention discloses a middle pipe, which enables rainwater entering a post-treatment assembly through a tail pipe to be discharged from the middle pipe in time, avoids the post-treatment carrier from being polluted by the rainwater, and improves the discharge performance.
The invention also provides a post-treatment assembly, wherein the intermediate pipe is arranged in the post-treatment assembly.
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 6, the present invention discloses an intermediate tube.
The middle pipe is vertically arranged at the bottom of an inner cavity of a communicating pipe 3 which is communicated with the exhaust tail pipe through the aftertreatment assembly 5. It will be appreciated that in other embodiments, the intermediate pipe may also be arranged in a near vertical position at the bottom of the inner cavity of the communication pipe 3.
The middle pipe comprises a middle pipe main body 1 and an inner pipe 2, wherein the inner pipe 2 is arranged at the bottom of the side wall of the middle pipe main body 1, and the middle pipe main body 1 and the inner pipe 2 are fixedly connected together. Openings are formed in two ends of the middle pipe main body 1 and the inner pipe 2, an opening at one end of the inner pipe 2 is positioned outside the middle pipe main body 1, and an opening at the other end of the inner pipe is positioned inside the middle pipe main body 1; the opening at the lower end of the intermediate pipe body 1 communicates with the outside of the aftertreatment assembly 5. Specifically, the intermediate pipe body 1 is vertically disposed at the bottom of the inner cavity of the communicating pipe 3.
The inner pipe 2 is used for guiding out rainwater stored in the inner cavity of the communicating pipe 3 into the middle pipe main body 1, and the middle pipe main body 1 is used for guiding out the introduced rainwater from the post-treatment assembly 5.
The intermediate pipe is added in the communicating pipe 3 of the aftertreatment assembly 5, and when rainwater enters the communicating pipe 3 along the tail pipe and is accumulated, the rainwater flows into the intermediate pipe main body 1 through the inner pipe 2 by utilizing the principle of a communicating vessel and is discharged out of the aftertreatment assembly 5.
At the same time, the intermediate pipe can avoid exhaust gas from being discharged from the pipe orifice (lower end opening) for drainage of the intermediate pipe body 1. When the engine works, under the action of the upward flow of waste gas, the upper part of the middle pipe main body 1 forms a low pressure area B, the bottom of the post-treatment assembly 5 is a high pressure area C, waste gas at the lower part of the post-treatment assembly 5 enters the middle pipe main body 1 through the inner pipe 2 and flows upwards at a high speed, and flows out at a high speed through an opening communicated with the middle pipe main body 1 through the inner pipe 2, and a certain jet siphon is formed at the lower part of the middle pipe main body 1, so that the pressure at the position of an opening (an opening at the lower end) of the middle pipe main body 1 for draining water is balanced with or slightly lower than the atmospheric pressure, and the waste gas is ensured not to be discharged out of the post-treatment assembly 5 through the opening of the middle pipe main body 1 for draining water, or a small part of air in a hood enters the post-treatment assembly 5 to be discharged along with the waste gas through the opening of the middle pipe main body 1.
Specifically, the bottom of the intermediate pipe body 1 is fixedly connected with the communicating pipe 3. The bottom end position of the middle pipe main body 1 is provided with an elongated pipe body 11, one end of the elongated pipe body 11 is communicated with the bottom end opening of the middle pipe main body 1, and the other end of the elongated pipe body is communicated with the outside of the aftertreatment assembly 5. By providing an elongated tubular body 11, exhaust gas is advantageously prevented from exiting through this port. The opening for draining water at the lower end of the elongated tubular body 11 is a drain opening 12.
In one embodiment, the opening of the inner tube 2 at the outside of the intermediate tube body 1 is a horn-shaped opening, which is a water inlet 21, and the opening of the inner tube 2 at the inside of the intermediate tube body 1 is an injection port 22. For convenience in forming jet flow, the inner tube 2 is an L-shaped tube, one end of the water inlet 21 is arranged in a horizontal structure, and one end of the jet port 22 is arranged in a vertical structure. The water inlet 21 is arranged in a horn shape, so that the accumulated rainwater can enter the inner pipe 2 to be discharged conveniently.
Further, in order to prevent rainwater from entering the inside of the aftertreatment assembly 5 through the communicating pipe 3 and polluting the aftertreatment carrier 4, the height of the inner pipe 2 is lower than the height of the through hole communicating with the communicating pipe 3 and the aftertreatment assembly 5, so that when the accumulated water does not enter the inside of the aftertreatment assembly 5, a communicating vessel is formed in the intermediate pipe to guide out the accumulated water. Specifically, the height of the middle pipe main body 1 is higher than the height of the through hole communicating with the communicating pipe 3 and the post-treatment assembly 5, so that the exhaust gas flowing through the through hole is prevented from interfering with the air pressure in the middle pipe main body 1. It will be understood that the above-mentioned through holes do not refer to a single through hole, but rather to groups of uniformly distributed through holes.
In order to adapt to the high-temperature use environment, in a specific embodiment, the middle pipe main body 1 and the inner pipe 2 are made of stainless steel, and the stainless steel is adopted, so that the phenomenon of corrosion can be well avoided, and the service life of the structure is prolonged.
Specifically, the intermediate pipe body 1 and the elongated pipe body 11 are integrally cast. In another embodiment, the intermediate tube body 1 and the elongated tube body 11 are welded together seamlessly.
When the rainwater enters the post-treatment assembly 5 for accumulation in use, the water accumulated in the post-treatment assembly 5 enters the middle pipe main body 1 through the inner pipe 2 and then is discharged out of the post-treatment assembly 5 through the water outlet 12 by utilizing the principle of a communicating vessel as shown in fig. 5. When the engine works, as shown in fig. 6, under the action of the upward flow of the exhaust gas, a negative pressure or low pressure area is formed at the upper part of the middle pipe main body 1, the exhaust gas at the lower part of the middle pipe main body 1 enters through the water inlet 21 and flows upwards at a high speed and flows out through the jet orifice 22, a certain jet siphon is formed at the lower part of the middle pipe main body 1, so that the pressure at the position of the water outlet 12 is balanced with the atmospheric pressure or slightly lower than the atmospheric pressure, the exhaust gas is ensured not to be discharged out of the bottom of the aftertreatment assembly 5 through the water outlet 12, or a small part of air in the hood enters into the aftertreatment assembly 5 through the water outlet 12 and then rises, and finally is discharged from the tail pipe along with the exhaust gas.
The invention also discloses a post-treatment assembly 5, wherein the bottom of the inner cavity of the post-treatment assembly 5 is provided with a middle pipe, and the middle pipe is the middle pipe disclosed in any embodiment.
Since the bottom of the post-treatment assembly 5 has the above-mentioned intermediate pipe, the post-treatment assembly 5 has the technical advantages corresponding to the above-mentioned intermediate pipe, and will not be described herein.
The arrow direction in fig. 2 and fig. 4 to 6 is the fluid flow direction. The arrows in fig. 2 are the directions in which the stormwater flows into the aftertreatment assembly.
