Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas field pollution removal and oil collection, in particular to a movable oil collection device. Background Art

[0002] A large amount of waste oil is produced during the oil production process, so each oil production plant is equipped with oil removal tanks and waste oil pools to store these intermediate products.

[0003] For example, CN 210459149 U discloses a movable oil collection device comprising a traction frame, a handle, a bearing frame, a left buoy, an oil collecting trough, a middle buoy, a circular tube, and a right buoy. The traction frame is positioned on one side of the oil collecting trough, the handle is positioned at the upper end of the trough, the bearing frame is positioned on the left and right buoys, and the left and right buoys are symmetrically positioned at either end of the trough. The middle buoy is positioned below the trough and positioned midway between the left and right buoys. The circular tube is positioned between the lower ends of the left and right buoys and extends through the middle buoy. The oil collecting trough is also equipped with a bending device. This device is suitable for light or medium viscosity floating oil. When collecting oil, it is immersed in the sewage surface to effectively remove surface oil contamination. However, there is a problem: the oil collecting trough must be submerged in the pool to collect oil, which results in the entire device being contaminated by wastewater, easily corroded, and requiring cleaning. Utility Model Content

[0004] The purpose of the utility model is to provide a movable oil collecting device with reasonable structure and reliable use to solve the above problems. During the oil collecting process, the entire device does not need to be immersed in the pool, which ensures the cleanliness of the outside of the device. It is also flexible to use and has high oil collecting efficiency.

[0005] The technical solution of the utility model is:

[0006] The top end of the oil pump stretches out the side of the oil pumping station and the bottom end of the oil pumping station is fixed with a button bar, and the button bar pushes the button to push the top of the oil pumping station to push the top of the oil pumping station to the bottom of the oil pumping station.

[0007] The movable oil collecting device mentioned above has traction ears on the left and right sides of the front side wall of the oil collecting tank.

[0008] The movable oil collecting device mentioned above has a tapered oil collecting port at the lower end of the oil collecting riser.

[0009] The movable oil collecting device has a plurality of oil collecting risers in the front oil collecting assembly and they are arranged in two rows, front and rear, on the horizontal support plate; the rear oil collecting assembly has a plurality of oil collecting risers and they are arranged in two rows, front and rear, on the horizontal support plate.

[0010] The movable oil collecting device mentioned above has an oil drain port at the bottom of the rear side wall of the oil collecting tank.

[0011] The beneficial effects of the utility model are:

[0012] During operation, the oil recovery tank is supported above the sump using the front and rear support wheels. The left and right telescopic cylinders are activated to lower the horizontal support plate, allowing the lower end of the oil recovery riser to penetrate the floating oil layer. The oil pump is activated, creating negative pressure in the riser, which draws the floating oil into the tank. During the recovery process, the tank can be connected to other equipment using the towing lugs, allowing it to be moved along the length of the sump for efficient oil recovery. The entire unit does not need to be immersed in the sump during the recovery process, ensuring a clean exterior. It also offers flexibility and high recovery efficiency.

DETAILED DESCRIPTION

[0016] The utility model is described in detail according to the accompanying drawings.

[0017] like Figure 1 、 Figure 2 As shown, the movable oil collecting device includes an oil collecting tank 1, and a front supporting wheel group 9 and a rear supporting wheel group 4 are provided at the bottom of the oil collecting tank 1. The front supporting wheel group 9 and the rear supporting wheel group 4 include a left supporting wheel and a right supporting wheel respectively.

[0018] The bottom of the oil collection tank 1 is equipped with a front oil collection assembly and a rear oil collection assembly. Each assembly comprises a horizontal support plate 14, multiple oil collection risers 12 extending through the horizontal support plate 14, a telescopic tube 11 connected to the upper ends of the oil collection risers 12, and a left telescopic cylinder 15 and a right telescopic cylinder 13 connected to the left and right ends of the horizontal support plate 14. The left and right telescopic cylinders 15 and 13 are respectively fixed to the left and right side walls of the oil collection tank 1. The upper ends of the telescopic tubes 11 are fixed to the bottom of the oil collection tank 1 and communicate with the oil collection tank 1. The oil collection tank 1 has an internal compartment 7, within which an oil pump 6 is housed. The inlet line of the oil pump 6 is connected to each of the telescopic tubes 11 via a confluence line 2. The outlet line 5 of the oil pump 6 passes through the internal compartment 7 and communicates with the oil collection tank 1.

[0019] In this embodiment, the front oil collecting assembly comprises multiple vertical oil collecting pipes 12, arranged in two rows, front and rear, on a horizontal support plate 14. The rear oil collecting assembly comprises multiple vertical oil collecting pipes 12, arranged in two rows, front and rear, on a horizontal support plate 14. The lower ends of the vertical oil collecting pipes 12 are provided with tapered oil receiving ports. The front sidewalls of the oil collecting tank 1 are provided with traction lugs 8, respectively, on the left and right sides. The bottom of the rear sidewall of the oil collecting tank 1 is provided with an oil drain port 3.

[0020] Working principle:

[0021] When in use, the oil collecting tank 1 is supported above the slop oil pool 10 by the front supporting wheel group 9 and the rear supporting wheel group 4, and the left supporting wheel and the right supporting wheel are supported in the pre-set tracks on the left and right sides of the slop oil pool 10, so that the oil collecting tank 1 spans above the slop oil pool 10.

[0022] Activating the left and right telescopic cylinders 15 and 13 lowers the horizontal support plate 14, allowing the lower end of the oil-collecting riser 12 to penetrate the floating oil layer. The oil pump 6 is then activated, creating negative pressure in the oil-collecting riser 12, thereby drawing the floating oil into the oil-collecting tank 1. During the oil-collecting process, the oil-collecting tank 1 can be moved along the length of the sump 10 using the traction lugs 8 to connect with other equipment, achieving efficient oil collection.

[0023] After the oil is collected, the left and right telescopic cylinders 15 and 13 are started to lift the horizontal support plate 14, so that the lower end of the oil collection riser 12 is raised and higher than the upper edge of the slop oil pool 10, and the oil collection tank 1 is moved to the far end under the action of the traction equipment.

[0024] The above detailed description of the embodiments of the present invention is intended to be a preferred embodiment of the present invention and should not be construed as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the present invention shall still fall within the scope of this patent.
