Description

Technical Field

[0001] The utility model relates to a purging device, in particular to a purging device for oil and gas gathering and transportation pipelines, belonging to the technical field of pipeline purging. Background Technique

[0002] The gathering and transportation pipelines include the oil (gas) outlet pipelines from a single oil (gas) well to an oil (gas) treatment plant (or treatment device), and the oil (gas) gathering pipelines from the treatment plant to an oil (gas) storage tank or the first station of a long-distance pipeline. During the installation process, in order to avoid having excess gas and impurities inside the pipeline, generally before installation, workers need to purge the pipeline by introducing gas.

[0003] An environment-friendly gas pipeline purging device disclosed in the Chinese Patent Application Publication Specification CN216989007U includes a gas pipeline. A pressure detection device is installed on the gas pipeline. An installation frame one is installed on the left side of the gas pipeline. A threaded rod one penetrates through the upper part of the installation frame one close to the gas pipeline. The upper part of the threaded rod one is connected to a rotary handle one, and the lower part of the threaded rod one is connected to an upper arc plate one. A lower arc plate one is installed below the installation frame one close to the gas pipeline. A dust collection tank is installed below the installation frame one. An installation frame two is installed on the right side of the gas pipeline. A threaded rod two penetrates through the upper part of the installation frame two close to one side of the gas pipeline. The upper part of the threaded rod two is connected to a rotary handle two, and the lower part of the threaded rod two is connected to an upper arc plate two. The utility model is beneficial to cleaning the pipeline.

[0004] After the purging operation of the above device is completed, workers determine whether the inside of the pipeline is cleaned by observing whether there is dust adhered to the dust adhesion plate. In order to obtain accurate detection results, a new dust adhesion plate needs to be replaced every time it is detected. Since the installation frame one needs to be removed first to replace the dust adhesion plate of this device, the detection efficiency is reduced. Moreover, during the purging process of the pipeline, the pressure when the gas blows out from the end of the pipeline is relatively large, which is likely to cause a large impact on the end of the pipeline and there is a risk of impact on people or objects at the end of the pipeline.

[0005] Therefore, a purging device for oil and gas gathering and transportation pipelines is proposed here. Summary of the Utility Model

[0006] The utility model provides a purging device for oil and gas gathering and transportation pipelines to solve the problems in the prior art that the operation of workers for installing the dust adhesion plate each time is relatively troublesome, reducing the detection efficiency of the device, and during purging, the pressure when the gas blows out from the end of the pipeline is relatively large, posing a risk of impact on people or objects at the end of the pipeline.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 The embodiment of the utility model provides an oil and gas gathering pipeline purging device, including an installation box 1 and an air compressor 2. The installation box 1 is provided with a detection component 3 inside. The detection component 3 includes a dust sticking plate 301. A mounting groove 302 is provided above the installation box 1. The dust sticking plate 301 is slidably connected to the inner wall of the mounting groove 302. A clamping seat 303 is fixed to the inner bottom wall of the installation box 1. A clamping groove 304 is provided above the clamping seat 303. The dust sticking plate 301 is clamped with the inner wall of the clamping groove 304. The clamping seat 303 can play a role of limiting support for the lower end of the dust sticking plate 301 through the clamping groove 304, thereby ensuring the stability of the dust sticking plate 301 in use. When the pipeline is purged, the dust sticking plate 301 is not installed. When the pipeline needs to be detected for dust, the dust sticking plate 301 is inserted into the interior of the installation box 1 through the mounting groove 302, and the bottom of the dust sticking plate 301 is clamped with the clamping groove 304, so that the installation of the dust sticking plate 301 can be completed.

[0030] The upper part of the installation box 1 is provided with a slot sealing mechanism 4. The slot sealing mechanism 4 includes a support block 401. An expansion rod 402 is fixed on the outer surface of the support block 401. A first spring 403 is sleeved on the outer surface of the expansion rod 402. The extended end of the expansion rod 402 is fixed with a toggle piece 404. A wind shield 405 is fixed on the bottom surface of the toggle piece 404. Two sliding slots 406 are formed inside the installation box 1. The inner wall of each sliding slot 406 is slidably connected with the wind shield 405. Under the action of the elastic force of the first spring 403, a horizontal thrust can always be applied to the toggle piece 404, so that the wind shield 405 can automatically slide along the inner wall of the sliding slot 406. And the side surface of the sliding slot 406 and the handle above the dust sticking plate 301 can limit the wind shield 405.

[0031] A dust filtering mechanism 5 is arranged inside the installation box 1. The dust filtering mechanism 5 includes a dust filtering plate 501. The dust filtering plate 501 is slidably connected with the inner wall of the installation box 1. Equally spaced sliding rods 502 are slidably connected inside the dust filtering plate 501. Fixed blocks 503 are fixed at both ends of each sliding rod 502. The fixed blocks 503 can support the sliding rods 502. When the dust filtering plate 501 is blown by the wind, it will slide along the outer surface of the sliding rods 502. Each fixed block 503 is fixed to the inner wall of the installation box 1. A second spring 504 is sleeved on the outer surface of each sliding rod 502. When the dust filtering plate 501 slides, it will compress the second spring 504. Under the elastic action of the second spring 504, the effect of buffering the wind pressure blown out at the end of the pipeline can be achieved.

[0032] Please refer specifically to Figure 2 , two convex blocks 407 are fixed on the outer surface of the wind shield 405. During the purging operation, the installation slot 302 is blocked by the wind shield 405 to prevent the airflow from leaking dust from the installation slot 302.

[0033] Please refer specifically to Figure 1 and Figure 3 , a dust collection chamber 505 is opened below the installation box 1. A discharge pipe 506 is arranged at the bottom of the dust collection chamber 505. After the purging is completed, under the action of gravity, the dust will automatically fall into the dust collection chamber 505.

[0035] Working principle: When the device is used for purging the collecting and transporting pipeline, there is no need to install the dust sticking plate 301 in the installation box 1. Under the elastic action of the spring 403, a horizontal thrust can be always applied to the wind shield 405, so that the side of the wind shield 405 can be against the inner wall of the sliding groove 406. At this time, the wind shield 405 can block the installation groove 302 to prevent the airflow from carrying dust from leaking from the installation groove 302 during the purging operation. When it is necessary to detect the dust in the collecting and transporting pipeline, the wind shield 405 is moved by pushing the toggle piece 404 to expose the installation groove 302, and then the dust is removed. The dust sticking plate 301 is inserted into the interior of the installation box 1 through the installation slot 302, and the bottom of the dust sticking plate 301 is engaged with the slot 304, and then the toggle plate 404 is released. Under the elastic action of the spring 403, the side of the wind shield plate 405 is abutted against the handle above the dust sticking plate 301, so that the two protrusions 407 can limit the upper end of the dust sticking plate 301, preventing the dust sticking plate 301 from falling off from the installation slot 302 during use, thereby completing the installation of the dust sticking plate 301. In summary, the present device can achieve the effect of facilitating the staff to quickly disassemble and assemble the dust sticking plate 301.

[0036] When the device is blowing the gathering and transportation pipeline, the dust filter plate 501 will slide along the outer surface of the sliding rod 502 when it is affected by the airflow, thereby compressing the multiple springs 504. Under the elastic action of the springs 504, a thrust in the opposite direction of the air blowing can always be applied to the dust filter plate 501, thereby achieving the effect of buffering the wind pressure blown out from the end of the pipeline, thereby reducing the impact risk of people or objects at the end of the pipeline.
