AI Technical Summary
The existing exhaust gas emission treatment conveying pipelines are prone to fall off due to loose connection between the outer pipe and the inner wall of the equipment during long-term use. The exhaust gas cannot evenly contact the inner wall of the pipeline due to the impact of the air pressure during the transportation process, resulting in uneven stress and excessive wear of the inner wall.
The structure of the inner pipe is adopted to wrap the inner pipe. The inner wall of the inner pipe is equipped with multiple Kevla reinforcement strips, and the thermal insulation connection sleeve structure is wrapped on the outside of the outer pipe, including a bonding positioning ring, a positioning annular deformation groove, a thermal insulation cover connecting ring and an insulation cover. These structures enhance the connection stability and thermal insulation effect of the pipe.
The Kevla reinforcement strip increases the strength and rotary diversion effect of the inner pipe, so that the exhaust gas evenly contacts the inner wall of the inner pipe, and improves the stability and life of the pipe; the thermal insulation connection sleeve structure prevents the outer pipe from falling off and reduces energy loss during the waste gas transportation.

Technical Field
[0001] The utility model relates to the field of pipelines, in particular to an exhaust gas emission treatment and delivery pipeline. Background Art
[0002] Exhaust gas treatment pipelines are pipelines for transporting exhaust gas. They are mainly installed on exhaust gas emission equipment to transport exhaust gas to a fixed location for discharge. They are usually composed of a double-layer structure, with the outer layer playing a protective role and the inner layer playing a corrosion-resistant role. They are widely used in various exhaust gas emission occasions.
[0003] When using the existing exhaust gas emission treatment and conveying pipeline, the pipeline is mainly inserted into the equipment for installation, and then used for exhaust gas transportation. Therefore, the outer wall of the outer pipeline is fitted with the inner wall of the equipment installation position. However, when the pipeline is used for a long time, the connection between the outer pipeline and the inner wall of the equipment will become loose, so it is easy to fall off and cannot be used stably. In addition, when the pipeline is transporting exhaust gas, the exhaust gas cannot evenly contact the inner wall of the pipeline due to the impact of air pressure, which makes the inner wall of the pipeline unevenly stressed, and also causes the pipeline to wear too quickly, and it cannot be used for a long time.

[0004] The main purpose of the utility model is to provide an exhaust gas emission treatment and delivery pipeline, which can effectively solve the technical problems raised by the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] As a further solution of the utility model, the top connecting pipe and the bottom connecting pipe have the same size, and the top connecting pipe and the bottom connecting pipe are connected to the interior of the inner layer pipe.
[0008] As a further solution of the utility model, the Kevlar reinforcement strip is embedded in the inner wall of the inner layer pipe, and a plurality of Kevlar reinforcement strips are arranged in a spiral shape around the inner wall of the inner layer pipe.

[0010] As a further solution of the utility model, the fitting positioning ring is arranged in a cone shape, and a plurality of fitting positioning rings are arranged in a line around the outer pipe.
[0011] As a further solution of the utility model, the thermal insulation cover is sleeved on the outside of the outer layer pipe, the upper end of the thermal insulation cover is fixedly connected to the lower end of the upper fitting positioning ring, and the lower end of the thermal insulation cover is fixedly connected to the upper end of the lower insulation cover connecting ring.
[0012] Compared with the prior art, the utility model has the following beneficial effects: the Kevlar reinforcement strip is used to increase the strength of the inner pipe, and the spiral structure of the Kevlar reinforcement strip can play a rotating diversion effect on the exhaust gas passing through, so that the exhaust gas evenly contacts the inner wall of the inner pipe, thereby making the inner wall of the inner pipe evenly stressed, making the pipe more secure for long-term use;

DETAILED DESCRIPTION
[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] like Figure 1-Figure 4 As shown, an exhaust gas emission treatment and transportation pipeline includes an outer layer pipeline 1 and an inner layer pipeline 2, the outer layer pipeline 1 is wrapped around the outer side of the inner layer pipeline 2, the inner wall of the inner layer pipeline 2 is provided with a plurality of Kevlar reinforcement strips 3, a top connecting pipe 4 is fixedly installed at the upper end of the outer layer pipeline 1, a bottom connecting pipe 5 is fixedly installed at the lower end of the outer layer pipeline 1, mounting threads 6 are provided on the outer sides of the top connecting pipe 4 and the bottom connecting pipe 5, the outer side of the outer layer pipeline 1 is wrapped with a heat insulating connecting sleeve structure 7, the outer layer pipeline 1 and the inner layer pipeline 2 are connected as a whole, and constitute the main structural part of the pipeline.
[0021] In this embodiment, the top connecting tube 4 and the bottom connecting tube 5 have the same size, and the top connecting tube 4 and the bottom connecting tube 5 are connected to the interior of the inner layer pipe 2. The top connecting tube 4 and the bottom connecting tube 5 are threadedly connected to the connecting end of the pipe by installing threads 6, and the outer layer pipe 1 is inserted into the pipe for installation.
[0022] In this embodiment, the Kevlar reinforcement strips 3 are embedded in the inner wall of the inner pipe 2, and a plurality of Kevlar reinforcement strips 3 are arranged in a spiral shape around the inner wall of the inner pipe 2. The Kevlar reinforcement strips 3 have a spiral guide effect through the spiral structure.
[0023] In this embodiment, the thermal insulation connecting sleeve structure 7 includes a fitting positioning ring 8, a positioning annular variable groove 9, a heat insulation cover connecting ring 10 and a thermal insulation cover 11. Multiple fitting positioning rings 8 are fixedly sleeved on the outside of the outer pipe 1. The positioning annular variable groove 9 is opened at the bottom of the fitting positioning ring 8. The heat insulation cover connecting ring 10 is integrally formed on the outside of the fitting positioning ring 8. Multiple thermal insulation covers 11 are located between the multiple fitting positioning rings 8. The multiple fitting positioning rings 8 can be fitted and connected with the inner wall of the pipe when the outer pipe 1 is inserted into the pipe, thereby installing and fixing the outer pipe 1.
[0024] In this embodiment, the fitting positioning ring 8 is set in a conical shape, and multiple fitting positioning rings 8 are arranged in a line around the outer pipe 1. The fitting positioning ring 8 can elastically shrink and expand through the conical structure, so that the fitting positioning ring 8 can be pressed against the inner wall of the pipe.
[0025] In this embodiment, the thermal insulation cover 11 is sleeved on the outside of the outer pipe 1, the upper end of the thermal insulation cover 11 is fixedly connected to the lower end of the upper fitting positioning ring 8, and the lower end of the thermal insulation cover 11 is fixedly connected to the upper end of the lower thermal insulation cover connecting ring 10. The two fitting positioning rings 8 and the thermal insulation cover connecting ring 10 have the effect of installing a single thermal insulation cover 11, and the thermal insulation cover 11 has the effect of heat preservation.
[0026] It should be noted that the utility model is a waste gas emission treatment and delivery pipeline. When in use, the outer layer pipeline 1 and the inner layer pipeline 2 are the main parts of the pipeline. The outer layer pipeline 1 and the inner layer pipeline 2 are inserted into the equipment installation position. The outer layer pipeline 1 is connected to the inner wall of the equipment, and then the installation threads 6 on the top connecting pipe 4 and the bottom connecting pipe 5 are threadedly installed with the equipment. The waste gas is input and output through the top connecting pipe 4 and the bottom connecting pipe 5, and the waste gas passes through the inner layer pipeline 2. The inner layer pipeline 2 is used to contact the waste gas to achieve the effect of transportation. At the same time, the inner layer pipeline 2 is made of corrosion-resistant materials, which prolongs the service life of the pipeline.
[0027] When the exhaust gas is transported through the inner pipe 2, the Kevlar reinforcement strip 3 embedded in the inner wall of the inner pipe 2 has the effect of reinforcing it, and the Kevlar reinforcement strip 3 increases the strength of the inner pipe 2. In addition, the spiral installation structure of the Kevlar reinforcement strip 3 can have a rotational diversion effect on the exhaust gas passing through, so that the exhaust gas evenly contacts the inner wall of the inner pipe 2, thereby making the inner wall of the inner pipe 2 evenly stressed.
[0028] When the outer pipe 1 is inserted into the inner wall of the equipment and contacts therewith, the multiple fitting positioning rings 8 outside the outer pipe 1 contact the inner wall of the equipment, and the positioning annular variable groove 9 provided in the fitting positioning ring 8 enables the fitting positioning ring 8 to have an exaggerated shrinkage movement space. Therefore, after the fitting positioning ring 8 fits the inner wall of the equipment, it will shrink to a certain extent into the positioning annular variable groove 9, and then the fitting positioning ring 8 will elastically expand outward. Therefore, the expanded elastic force of the fitting positioning ring 8 firmly presses against the inner wall of the equipment to connect, preventing the outer pipe 1 from falling off from the connection with the pipeline, and the connection of the fitting positioning ring 8 forms a barrier between the outer pipe 1 and the pipeline, and the thermal insulation cover 11 is sleeved in the barrier between the outer pipe 1 and the pipeline to insulate the outer pipe 1 and reduce the energy loss of exhaust gas during transportation and lifting.
