Description

Technical Field

[0001] The utility model relates to the technical field of filtration, and more specifically to an automatic produced water filtration device for oil and gas field surface engineering. Background Art

[0002] An oil and gas field refers to the sum of oil reservoirs, gas reservoirs, and oil and gas reservoirs within the same area controlled by a single local structural unit. If there is only an oil reservoir within this local structural range, it is called an oil field; if there is only a gas reservoir, it is called a gas field. During the exploitation process of an oil and gas field, with the production of underground water in the oil and gas field, the produced water in the oil and gas field is mainly the water in the formation structure, which is brought to the surface together with crude oil and natural gas during the oil and gas production process. The quality of the produced water in the oil and gas field is complex and contains a large amount of impurities. Therefore, in real life, a filtration device is often used to filter it.

[0003] During the use of the existing filtration device, it can usually filter water in multiple layers. However, in actual use, due to a large amount of impurities, the filter screen needs to be cleaned in a timely manner. But usually, the filter component and the filtration device are connected and fixed by bolts, and it is inconvenient to disassemble during use, which affects the filtration efficiency of water. For this reason, we propose an automatic produced water filtration device for oil and gas field surface engineering. Summary of the Utility Model

[0007] Furthermore, the filtration mechanism includes a filter box. One side of the filter box is fixedly connected with a connection sealing plate, and connection limit blocks are symmetrically arranged on the surface of the connection sealing plate.

[0008] Furthermore, a connection handle is fixedly connected to the middle of the surface of the connection sealing plate.

[0009] Further, the fastening mechanism includes a fixed sleeve block, an electric telescopic rod is fixedly connected inside the fixed sleeve block, a limit disk is fixedly connected to the output end of the electric telescopic rod, a limit sleeve ring is fixedly sleeved on the outer side of the surface of the output end of the electric telescopic rod, and a movable limit arm is movably sleeved on the outer side of the surface of the output end of the electric telescopic rod.

Detailed implementation method

[0020] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the attached drawings in the present invention. In addition, the forms of each structure described in the following implementation manners are merely examples, and the present invention is not limited to the structures described in the following implementation manners. All other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] Refer to Figures 1-4 , the present invention provides an automatic produced water filtering device for oil and gas field surface engineering, including a filter box 1. The number of filter boxes 1 is two. A support column 2 is fixedly connected to the bottom end of the filter box 1. A fastening mechanism 3 is symmetrically arranged on the outer side of the surface of the filter box 1. A filtering mechanism 4 is arranged inside the filter box 1;

[0022] Among them, electric control valves 5 are fixedly connected to both the top and bottom of the filter box 1. A fixed connecting pipe 6 is connected to the connection port of the electric control valve 5. The other end of the fixed connecting pipe 6 is fixedly connected to an integrated pipe 7. A water delivery pipe 8 is fixedly connected to the surface of the integrated pipe 7.

[0023] Among them, the filtering mechanism 4 includes a filter cartridge 9. A connecting sealing plate 10 is fixedly connected to one side of the filter cartridge 9. Connecting limit blocks 11 are symmetrically arranged on the surface of the connecting sealing plate 10. After the fastening mechanism 3 is adjusted, the fastening mechanism 3 is no longer connected between the connecting limit blocks 11 and the connecting sealing plate 10, so that the connecting sealing plate 10 can be quickly moved, and the filter cartridge 9 can be pulled out from the inside of the filter box 1, so as to quickly disassemble and clean the filter cartridge 9, and the operation is convenient.

[0024] Among them, a connecting handle 12 is fixedly connected to the middle of the surface of the connecting sealing plate 10, which is convenient for pulling the connecting handle 12, so that the connecting sealing plate 10 and the filter cartridge 9 can be quickly moved, facilitating disassembly.

[0025] Among them, the fastening mechanism 3 includes a fixed sleeve block 13. An electric telescopic rod 14 is fixedly connected inside the fixed sleeve block 13. The output end of the electric telescopic rod 14 is fixedly connected with a limit disk 15. A limit sleeve ring 16 is fixedly sleeved on the outer side of the surface of the output end of the electric telescopic rod 14. An active limit arm 17 is movably sleeved on the outer side of the surface of the output end of the electric telescopic rod 14. The active limit arm 17 is located between the limit disk 15 and the limit sleeve ring 16. When the electric telescopic rod 14 pushes the limit disk 15, the limit sleeve ring 16 and the active limit arm 17 outwards, it drives the connecting limit block 11 and the connecting sealing plate 10 to move. At this time, the active limit arm 17 no longer squeezes the connecting sealing plate 10. Then, the active limit arm 17 is deflected on the outer side of the surface of the output end of the electric telescopic rod 14 and disengages from the inner side of the connecting limit block 11. Then, the connecting handle 12 is pulled to drive the connecting sealing plate 10 and the filter box 9 to move, and the filter box 9 is disassembled and cleaned, which is convenient to operate.

[0026] Among them, the cross-sectional shape of the connecting limit block 11 is L-shaped. The inner side of the connecting limit block 11 is mutually attached to the outer side of the surface of the active limit arm 17, which is convenient for the active limit arm 17 to be stably stuck inside the connecting limit block 11 and is convenient to operate.

[0027] Among them, a fixed support block 18 is provided on the inner wall of the filter box 1. The top of the fixed support block 18 is mutually attached to the bottom of the filter box 9, which is convenient for the fixed support block 18 to lift the filter box 9, so that the filter box 9 can be stably located inside the filter box 1 for use.

[0028] The working principle of the present utility model: During the use process, when it is necessary to disassemble and clean the filtering mechanism 4 inside one of the filter boxes 1, first, when disassembling and cleaning the filtering mechanism 4 inside one of the filter boxes 1, at this time, the electric control valve 5 on the top of the filter box 1 is closed, and the electric control valve 5 on the top of the other filter box 1 is opened, so that water can enter the other filter box 1 for filtering, and then the filtering mechanism 4 can be disassembled, washed and cleaned. During the disassembly process, the electric telescopic rod 14 pushes the limit disk 15, the limit sleeve ring 16 and the active limit arm 17 outwards, drives the connecting limit block 11 and the connecting sealing plate 10 to move. At this time, the active limit arm 17 no longer squeezes the connecting sealing plate 10. Then, the active limit arm 17 is deflected on the outer side of the surface of the output end of the electric telescopic rod 14 and disengages from the inner side of the connecting limit block 11. Then, the connecting handle 12 is pulled to drive the connecting sealing plate 10 and the filter box 9 to move, and the filter box 9 is disassembled and cleaned. The overall structure is simple and the operation is convenient.
