Description

Technical Field

[0001] The utility model relates to the technical field of pigging operation, in particular to a pigging sewage recovery device. Background Art

[0002] During pigging operation in oil and gas pipelines, a large amount of sewage and debris is generally generated. The sewage is discharged through the pipeline, and a container needs to be placed at the pipeline sewage outlet to collect and treat this sewage and debris to avoid environmental pollution. During the sewage collection process, as the pigging operation progresses to different stages, the amount of sewage generated by pigging is different, and the impact force of the sewage flowing out of the pipeline is different, resulting in different discharge distances of the sewage. The container for holding sewage at the sewage outlet is usually fixedly installed and cannot adjust its position according to the discharge distance of the sewage, so that the sewage cannot be accurately discharged into the container, causing environmental pollution.

[0003] Therefore, a technical solution is currently needed to solve the technical problem that during the pigging operation, the container for holding sewage cannot be aligned with the sewage discharge position, resulting in environmental pollution. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the technical problem that during the pigging operation, the container for holding sewage cannot be aligned with the sewage discharge position, resulting in environmental pollution, and provide a pigging sewage recovery device.

[0005] The utility model provides a pigging sewage recovery device, which includes a base. A recovery pool that can slide horizontally is arranged on the base. The top of the recovery pool has an opening, and a sewage outlet is arranged at the bottom of the recovery pool.

[0006] When the pigging sewage recovery device of the utility model is in use, the base is placed below the pipeline. During the pigging process, the sewage is discharged through the pipeline and enters the recovery pool on the base. When the discharge distance of the sewage changes during the pigging process, the recovery pool slides horizontally on the base so that the recovery pool can be aligned with the sewage discharge position, thereby avoiding a large amount of pigging sewage from scattering into the environment.

[0007] Preferably, the base includes two oppositely arranged support frames. Each support frame includes two columns, and a cross bar is connected between the two columns. Both sides of the recovery pool are slidably connected to the two cross bars respectively.

[0008] The columns are inserted into the ground for fixation, and the two columns support the cross bar to a suitable height to facilitate the installation of the recovery pool between the two cross bars.

[0009] Preferably, the base further includes a connecting rod, and the connecting rod is respectively connected to the two support frames.

[0010] The two support frames are connected together by a connecting rod to form an integral body, which can improve the structural stability of the entire base, thereby ensuring the stable installation of the recovery tank on the base and avoiding problems such as tipping and slipping.

[0011] Preferably, a slide rail is provided on the top of the cross bar, the slide rail is arranged along the length direction of the cross bar, extension plates are respectively arranged on both sides of the recovery tank, and a chute adapted to the slide rail is provided at the bottom of the extension plate.

[0012] By respectively arranging extension plates on both sides of the recovery tank and matching the chute at the bottom of the extension plate with the slide rail on the cross bar, a slidable connection between the recovery tank and the base is achieved.

[0013] Preferably, limiting blocks are respectively connected to both ends of the slide rail, and the width of the limiting block is greater than the width of the chute.

[0014] The limiting blocks play a blocking role for the recovery tank, which can prevent the recovery tank from sliding out of the slide rail and increase the error tolerance rate during the position adjustment process of the recovery tank.

[0015] Preferably, a plurality of rollers are provided on the bottom wall of the chute, and the rollers are used to abut against the slide rail.

[0016] The friction between the slide rail and the extension plate can be reduced, making the sliding process of the recovery tank along the slide rail smoother.

[0017] Preferably, a filter screen is detachably arranged at the sewage outlet.

[0018] The filter screen can block debris and sundries in the sewage, preventing debris and sundries from entering the sewage discharge process of the recovery tank. On the one hand, it is convenient to separately treat the sewage and the sundries, and on the other hand, it plays a role in protecting the sewage discharge pipeline and equipment.

[0019] Preferably, the filter screen is provided with an annular retaining wall, and the annular retaining wall is arranged around the edge of the filter screen.

[0020] The annular retaining wall and the filter screen enclose to form a barrel shape, which can increase the loading capacity of the filter screen for debris and sundries, enabling the debris and sundries to accumulate in the filter screen and facilitating the centralized cleaning of the debris and sundries.

[0021] Preferably, a limiting edge is provided at the top of the annular retaining wall, and the limiting edge abuts against the inner bottom wall of the recovery tank.

[0022] The annular retaining wall is embedded into the sewage outlet along with the filter screen, and the limiting edge at the top of the annular retaining wall abuts against the inner bottom wall of the recovery tank, realizing the detachable installation of the filter screen at the sewage outlet, which is simple to disassemble and assemble, so as to facilitate the rapid installation, disassembly and cleaning of the filter screen.

[0023] Preferably, a sewage pipe is connected to the sewage outlet, and a stop valve is connected to the sewage pipe.

[0024] The sewage discharge pipe is connected to the bottom of the sewage discharge pool, which can conveniently lead the sewage to a designated location for discharge through the sewage discharge pipe.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0026] In this application, a recovery pool that can slide horizontally is arranged on the base. During the pigging operation, when the impact force of the sewage changes, the position of the recovery pool can be adaptively adjusted on the base, thereby preventing a large amount of sewage from spilling into the environment.

[0042] Example 1

[0043] As Figure 1 、 2 、3、 Figure 4 and Figure 5 shown, a pigging sewage recovery device includes a base 1. A recovery tank 2 that can slide horizontally is arranged on the base 1. The top of the recovery tank 2 has an opening, and a sewage discharge port is provided at the bottom of the recovery tank 2.

[0044] During use, the base 1 is placed below the pipeline. During the pigging process, sewage is discharged through the pipeline and enters the recovery tank 2 on the base 1. When the distance that the sewage flushes out changes during the pigging process, the recovery tank 2 slides horizontally on the base 1 so that the recovery tank 2 can be aligned with the position where the sewage flushes out, thereby preventing a large amount of pigging sewage from spilling into the environment.

[0045] Base 1: The base 1 includes two relatively arranged support frames 11. The support frame 11 includes two columns 111. A cross bar 112 is connected between the two columns 111. The two sides of the recovery tank 2 are respectively slidably connected to the two cross bars 112. A slide rail 1121 for the sliding of the recovery tank 2 is arranged on the top of the cross bar 112. The slide rail 1121 is arranged along the length direction of the cross bar 112. Two connecting rods 12 are arranged between the two support frames 11. The two ends of the connecting rod 12 are respectively connected to the column parts of the support frame 11, so that the two support frames 1 are connected together to form a whole, which can improve the structural stability of the entire base 1, thereby ensuring the stable installation of the recovery tank 2 on the base 1 and avoiding problems such as tipping and slipping.

[0046] Recovery tank 2: Extension plates 21 are respectively arranged on both sides of the recovery tank 2. A chute 211 adapted to the slide rail 1121 is arranged at the bottom of the extension plate 21. A sewage discharge pipe 4 is connected to the sewage discharge port at the bottom of the recovery tank 2. The sewage discharge pipe 4 is used to lead the sewage to a designated place for discharge, and a stop valve 41 for controlling the on-off of the fluid is connected to the sewage discharge pipe 4.

[0047] Furthermore, limit blocks 1122 are respectively connected to both ends of the slide rail 1121. The width of the limit block 1122 is greater than the width of the chute 211. The limit block 1122 plays a blocking role on the recovery tank 2, which can prevent the recovery tank 2 from sliding out of the slide rail 1121 and increase the error tolerance rate during the position adjustment process of the recovery tank 2.

[0048] Furthermore, a plurality of rollers 212 are arranged on the bottom wall of the chute 211. The plurality of rollers 212 are uniformly arranged along the length direction of the chute 211. The rollers 212 are used to abut against the slide rail 1121, which can reduce the friction between the slide rail 1121 and the extension plate 21 and make the sliding process of the recovery tank 2 along the slide rail 1121 smoother.

[0049] Example 2

[0050] As Figure 1 , Figure 6 and Figure 7 shown, in this embodiment, the difference from Embodiment 1 is that a filter screen 3 is detachably arranged at the sewage outlet.

[0051] In this embodiment, the filter screen 3 can block debris in the sewage, preventing the debris from entering the sewage discharge process of the recovery tank 2. On the one hand, it facilitates the separate treatment of sewage and debris, and on the other hand, it plays a role in protecting the sewage discharge pipeline and equipment.

[0052] Furthermore, the filter screen 3 is provided with an annular retaining wall 31. The annular retaining wall 31 is arranged around the edge of the filter screen 3. The annular retaining wall 31 and the filter screen 3 enclose to form a barrel shape, which can increase the loading capacity of the filter screen 3 for debris, enabling the debris to accumulate in the filter screen and facilitating the centralized cleaning of the debris.

[0053] Even further, a limiting edge 32 is provided at the top of the annular retaining wall 31. The limiting edge 32 abuts against the inner bottom wall of the recovery tank 2. As the filter screen 3 is inserted into the sewage outlet, the limiting edge 32 at the top of the annular retaining wall 31 abuts against the inner bottom wall of the recovery tank 2, realizing the detachable installation of the filter screen 3 at the sewage outlet. The disassembly and assembly are simple, facilitating the quick installation, disassembly, and cleaning of the filter screen.

[0054] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
