Description

Technical Field

[0001] The invention relates to an explosion-proof full-automatic oil collecting device and method capable of adjusting the horizontality and draft of an oil collecting tank, and belongs to the technical field of petroleum and petrochemical production equipment. Background Art

[0002] During the oil production, gathering and transportation, and sewage treatment processes in oil fields, a lot of floating oil will accumulate on the liquid surface in containers such as oil separators, sedimentation tanks, sewage tanks, slop tanks, slop pools, and sewage pools. How to effectively collect and remove the floating oil from the tanks and pools is an important guarantee for the smooth and effective implementation of the various process links of oil field production, injection, and transportation. At the same time, it can also greatly reduce the scale of oil field ground construction and reduce the cost of oil field crude oil production. It is an important equipment in all links of oil field production. Existing oil recovery devices used in oilfield tanks and pools are mainly divided into two types: passive oil recovery devices (fixed oil recovery tanks) and active oil recovery devices (height-adjustable oil recovery devices). Passive oil recovery devices use oil to find the tank, while active oil recovery devices use the tank to find oil. Passive oil recovery monitors the liquid level in the container and controls the liquid volume at the inlet and outlet of the container (tank and pool) through a PLC, allowing the liquid level to change to find the tank surface to collect oil. Active oil recovery devices also monitor the liquid level of the medium and use the PLC to control the tank surface to find the liquid surface to collect oil. Both active and passive oil recovery devices are affected by insufficient oil level monitoring accuracy (the difference between the liquid level and the tank surface when the oil recovery device collects oil must be controlled to the millimeter level) and control lag caused by large containers, resulting in poor oil recovery effect, serious "empty collection" and "water collection" phenomena, and the draft of the oil recovery tank will also change over time. The draft of the oil recovery tank needs to be adjusted and checked according to the working status of the oil recovery device. According to the working principles of the two types of oil collection devices, the surface of the oil collection tank is required to be adjusted to a horizontal state after installation. However, as the temperature in the tank changes, the stress in the material and the attachments in the oil collection tank change, the horizontal state of the tank surface will change, making it impossible for the oil collection device to evenly collect the floating oil horizontally distributed on the liquid surface, resulting in "biased collection" or "water collection" states. At this time, the tank and pool are already filled with medium and flammable, toxic and harmful gases. The operator can no longer enter the tank and pool to adjust the level of the oil collection tank surface. If the tank and pool are cleaned again, the cost is very high and the cycle is very long. The above two It is an important reason that restricts the oil collection effect of the oil collection device, causing thicker floating oil to accumulate locally on the top of the liquid surface in the container. When its height reaches a certain limit, the functions of various containers will gradually decrease, mainly manifested in excessive oil content in the outlet medium. In order to maintain the final parameters of the system, the on-site operators pump the medium at the outlet of the container back to the previous process in a reflux manner, resulting in a large amount of energy and process resources being wasted. In order to level the oil collection tank, the tank and pool must be cleaned to a state where people can enter, which is time-consuming, labor-intensive, and expensive, and can easily cause ground pollution accidents. Therefore, how to make the oil collection device explosion-proof, how to adjust the draft of the tank surface at any time during the operation of the oil collection device, and how to adjust the level of the oil collection tank surface at any time during the operation of the oil collection device without cleaning the tank or entering the tank, are technical problems that need to be solved in this field. Summary of the Invention

During operation, the horizontal angle and the draft of the oil receiving tank can be adjusted directly on the top of the tank or pool.

[0060] In an embodiment, an explosion-proof, fully automatic, active oil collection device for adjusting the level of an oil collection tank at any time is installed on a tank or pool in an oil field. The device comprises an explosion-proof reduction motor, an upper sealing assembly, an explosion-proof, anti-rotation cylinder of a screw lifting mechanism, an explosion-proof safety inspection cover, a lower sealing assembly, a suspension assembly for adjusting the level of the oil collection tank, a draft adjustment rod assembly for the oil collection tank surface, a three-section assembly of the oil collection tank, eight major parts, a trapezoidal lifting screw, a mounting base, and other accessories. The details are as follows:

[0061] The explosion-proof reduction motor consists of a naturally cooled, fully enclosed explosion-proof motor, a reducer and a control panel. The output copper sleeve in the reducer transmits the torque of the explosion-proof motor to the trapezoidal lifting screw 1, driving the oil collecting tank of the oil collecting device to move up and down. A sealing assembly is designed at the bottom, which includes a pressure block and a skeleton sealing mounting groove.

[0062] The explosion-proof safety inspection cover 7 consists of a mounting base 13, a sealing cover hinge fixed end 14, a sealing cover hinge pin 15, a sealing cover hinge movable end (cover handle) 16, a sealing cover (edge ​​with a Dingqing rubber pad fixing groove) 17, a sealing cover quick opening and closing handle 18, a sealing cover pressing anti-stripping T-bolt 19, an anti-stripping T-bolt hinge fixed end 20 and a raised sealing edge 21. The raised sealing edge 21 is welded to the mounting base 13 and is a sealed fixed surface; the sealing cover hinge fixed end 14 is also welded to the mounting base 13, the sealing cover hinge movable end (cover handle) 16 is connected to the sealing cover hinge fixed end 14 through the sealing cover hinge pin 15, forming a hinge structure that can only rotate up and down around the sealing cover hinge pin 15, and the sealing cover (edge ​​with a Dingqing rubber pad fixing groove) 17 is welded to the sealing cover hinge movable end (cover handle) 16. The other end of the sealing cover's hinged movable end (cover handle) 16 is extended into a U-shaped structure. The bottom of the U-shaped structure is mounted concentrically with the sealing cover's anti-slip T-bolt 19, which secures the sealing cover's anti-slip T-bolt 19 to the hinged fixed end 20, forming a hinge structure. The upper external threaded portion engages with the threaded hole on the sealing cover's quick-open / close handle 18.

The sealing cover (with a t-shirt rubber gasket retaining groove on the edge) 17 is designed with a C-shaped groove corresponding to the raised sealing edge 21. A circular t-shirt rubber gasket is embedded in the C-shaped groove to prevent the sealing cover (with a t-shirt rubber gasket retaining groove on the edge) 17 from falling off when opened. The length of the U-shaped structure at the movable hinge end (handle) 16 of the sealing cover is determined by the length of the external threaded section of the sealing cover's anti-stripping T-bolt 19. Only when the quick-open / close handle 18 is fully rotated to the uppermost point of the external thread of the sealing cover's anti-stripping T-bolt 19 can the sealing cover's anti-stripping T-bolt 19 be removed from the U-shaped structure at the movable hinge end (handle) 16, allowing the sealing cover (with a retaining groove for a T-shaped rubber pad on the edge) 17 to be opened. Both the sealing cover hinge pin 15 and the sealing cover's anti-stripping T-bolt 19 are made of wear-resistant and high-strength beryllium bronze.

[0063] The mounting seat assembly 3 is a welded part of various functional components, and is used to install four components: the oil collecting tank surface draft depth adjustment rod assembly 5, the explosion-proof safety inspection cover 7, the oil collecting tank horizontal adjustment rod assembly 8 and the explosion-proof anti-rotation cylinder 9. The explosion-proof safety inspection cover 7 and the explosion-proof anti-rotation cylinder 9 are connected by flanges, and a Dingqing rubber pad is installed between the flanges during installation. The upper ends of the oil collecting tank surface draft depth adjustment rod assembly 5 and the oil collecting tank horizontal adjustment rod assembly 8 are reserved with external hexagonal corners, which are located 50 mm directly below the sealing cover (with a Dingqing rubber pad fixing groove on the edge) 17 when the explosion-proof safety inspection cover 7 is closed. After opening the explosion-proof safety inspection cover 7, a T-shaped hexagonal wrench is used to conveniently adjust the draft depth and horizontality of the oil collecting tank surface.

[0064] The explosion-proof and rotation-proof cylinder 9 receives the torque output from the power source (electric device, handwheel, etc.) 2 at the upper end of the trapezoidal lifting screw 1, and the lower end of the trapezoidal lifting screw 1 is connected to the lifting rod 24 through the screw and the rod connecting pin 25. The lower end of the lifting rod 24 is welded with an L-shaped equipment hanging bracket 28 (the bracket structure is different depending on the equipment) and welded into one; the middle flange of the explosion-proof and rotation-proof cylinder 9 is fixed to the flange of the mounting seat assembly 3 with bolts, and the flanges are sealed with Dingqing rubber gaskets.
