Description

Technical Field

[0001] The utility model relates to the technical field of oil extraction, in particular to an anti-blocking filtering device for oil extraction. Background Technique

[0002] Oil extraction refers to the act of excavating and extracting oil where oil is stored. During the process of oil extraction, the driving mode of oil and gas flowing from the reservoir into the bottom of the well and then rising from the bottom of the well to the wellhead. When extracting oil, oil is always produced through drilling, and mud will appear during drilling, and the mud needs to be filtered.

[0003] Chinese Patent Authorization Publication No. CN215538725U discloses a filtering device for oil drilling mud, including a main body of the filtering device. The upper surface of the main body of the filtering device is screwed and connected with a protective cover through a threaded structure. An inlet is fixedly installed in the middle of the upper surface of the protective cover through bolts. The lower surface of the main body of the filtering device is fixedly installed with an outlet through bolts. An inner plate is welded and fixed at the middle position inside the main body of the filtering device. First card slots are equidistantly arranged at the edge of the inner plate; by designing the first card slots inside the inner plate and the clamping plates at the edge of the filter screen, it is avoided that the filter screen inside the filtering device is directly fixedly installed through bolts. After long-term use, the internal bolts rust and the filter screen is damaged, making it inconvenient to disassemble and replace the filter screen. When the filter screen is damaged after long-term use, at this time, the latch can be pulled to disengage the latch from the inside of the first and second card holes, and the filter screen can be rotated to disengage the clamping plate from the inside of the first card slot.

A suction filtration box is arranged inside the second filtration combined body, and activated carbon is arranged inside the suction filtration box. One end of the suction filtration box is connected to a water outlet pipe, and the other end of the suction filtration box is connected to a sludge discharge pipe. A water pump is connected to the outer side of the water outlet pipe.

[0007] Preferably, connection seats are fixed to both the side of the first filtration combined body close to the second filtration combined body and the side of the second filtration combined body close to the first filtration combined body, and the connection seats are connected by first bolts.

[0008] Preferably, a limiting block is fixed to the side of the first filtration combined body close to the second filtration combined body, and a limiting groove is arranged on the side of the second filtration combined body close to the first filtration combined body, and the limiting groove and the limiting block are connected in a clamping manner.

[0009] Preferably, the sizes of the limiting blocks are all matched with the sizes of the limiting grooves, and the cross-sections of the limiting blocks and the limiting grooves are both arranged in an L shape.

[0012] Compared with the prior art, the beneficial effect of the present utility model is that the anti-blocking filtration device for oil extraction realizes the function of facilitating anti-blocking suction filtration.

[0013] By arranging blades inside the first filtering combined body, when the muddy water enters from the mud delivery pipe, the blades stir and crush the incoming muddy water, enabling the soil blocks in the muddy water to mix into the muddy water, which facilitates subsequent suction filtration and discharge. Secondly, the arranged combined U-shaped pipe structure addresses the problem of unequal water speeds before and after and the unstable force factors of the water flow generated when the muddy water flows through the blades, which may affect subsequent suction filtration and discharge operations, thus realizing the main function of preventing blockage during use. At the same time, by setting the first filtering combined body and the second filtering combined body in a combined structure, it is convenient to maintain and repair the internal components after disassembly and separation, and it is also convenient to clean the interior, so as to improve the overall use effect.

[0014] Through the arranged suction filtration box, three pipes are connected inside it, namely the mud delivery pipe, the water outlet pipe, and the mud discharge pipe. Activated carbon is fixedly connected at the connection of the water outlet pipe, which is used to filter the mud in the muddy water and allow the water to flow out from the water outlet pipe end, and the remaining muddy water flows out through the mud discharge pipe.
