[0002] Oil extraction, as an important industrial activity for the excavation and extraction of underground oil resources, involves a complex process that drives oil and gas from the reservoir into the bottom of the well and then up to the wellhead.

[0003] Drilling is a crucial step in mining operations, but it generates a large amount of drilling mud. Traditional manual mud filtration methods are inefficient and difficult to control due to the heavy reliance on manpower. A more significant problem is the difficulty in accurately separating drilling mud from rock cuttings, causing valuable geological information and potential for utilization to be lost with the mud. This results in resource waste and hinders the secondary development and utilization of rock cuttings in subsequent geological analysis and material processing. Therefore, there is an urgent need for drilling mud filtration equipment. Utility Model Content

[0035] The present invention will now be described in further detail with reference to the accompanying drawings:

[0036] like Figure 1-2 As shown, a drilling mud filtration device according to this utility model includes a shell 1, a filtration assembly, and a guide plate 6. The shell 1 has a feed inlet 1-1 at the top and a discharge outlet 1-2 and a waste hopper 1-3 on the side. The shell 1 provides overall support and protective space for the device. The filtration assembly is located inside the upper part of the shell 1 and includes a filter cylinder 2 and a spiral baffle 3 installed inside the filter cylinder 2. The filter cylinder 2 is rotated by a power assembly. A waste outlet 14 is provided on the side of the filter cylinder 2 near the waste hopper 1-3. The feed inlet 1-1 is connected to the inside of the filter cylinder 2 through a feed pipe 15. Rock cuttings trapped in the filter cylinder 2 are conveyed to the waste outlet 14 through the spiral baffle 3. The guide plate 6 is located inside the lower part of the shell 1 and is inclined towards the discharge outlet 1-2.

[0037] In this embodiment, by setting a power component to drive the filter cylinder 2 to rotate, and combining it with the spiral baffle 3 to automatically transport rock cuttings, the mechanized operation of mud filtration is realized, which greatly improves the processing efficiency and reduces the reliance on manual labor. The spiral baffle 3, together with the waste port 14 and the waste hopper 1-3, can push the rock cuttings in the filter cylinder 2 to the waste port 14 to achieve efficient separation of mud and rock cuttings and reduce rock cuttings loss. At the same time, the collection of rock cuttings through the waste hopper 1-3 also avoids resource waste.

[0038] Specifically:

[0039] like Figure 1-2As shown, in the above embodiment, preferably, the discharge port 1-2 and the waste hopper 1-3 are respectively arranged on the left and right sides of the outer casing 1. An operation button, display screen, and indicator lights are also provided on the upper front of the outer casing 1, and a cabinet door for easy opening, maintenance, and cleaning is provided on the lower front of the outer casing 1.

[0040] In the above embodiments, preferably, the filter assembly further includes a first concave sleeve 4 and a second concave sleeve 5; wherein, the filter cylinder 2 is rotatably disposed on the inner side of the first concave sleeve 4 and the second concave sleeve 5 via bearings, and the power assembly is fixed on the outer side of the first concave sleeve 4; the first concave sleeve 4 and the second concave sleeve 5 are also connected to the inner wall of the outer shell 1 via angle adjustment mechanisms, which are used to adjust the tilt angle of the filter cylinder 2.

[0041] In the above embodiment, preferably, the injection tube 15 passes through the first concave sleeve 4 and connects the injection port 1-1 and the inner cavity of the filter cylinder 2; the second concave sleeve 5 is provided with a waste port 14 on the side near the waste hopper 1-3.

[0042] In the above embodiments, preferably, both the first concave sleeve 4 and the second concave sleeve 5 are in the shape of concave sleeves.

[0043] In the above embodiment, preferably, the angle adjustment mechanism includes a hydraulic cylinder 10 and a rotating shaft 11; wherein, the hydraulic cylinder 10 is disposed on the outside of the first concave sleeve 4, and the rotating shaft 11 is disposed on the outside of the second concave sleeve 5. In specific installation, the cylinder end of the hydraulic cylinder 10 is fixed to the inner wall of the outer casing 1, and the extended end of the hydraulic cylinder 10 is inclined downward and hinged to the lower end of the first concave sleeve 4; the outer center of the second concave sleeve 5 is hinged to the opposite inner wall of the outer casing 1 through the rotating shaft 11. When it is necessary to adjust the angle of the filter cylinder 2, by controlling the extension length of the piston rod of the hydraulic cylinder 10, the first concave sleeve 4 can be pressed down, thereby causing the end of the filter cylinder 2 close to the first concave sleeve 4 to tilt downward. At the same time, due to the rotating shaft 11 at the outer center of the second concave sleeve 5 at the other end of the filter cylinder 2, the other end of the filter cylinder 2 rotates downward, thereby achieving the tilt setting of the filter cylinder 2.

[0044] like Figure 3-4As shown, in the above embodiment, preferably, the power assembly includes a motor 7, a transmission shaft 8, and a connecting shaft 9. The motor 7 is fixed to the outside of the first concave sleeve 4, and the output end of the motor 7 is connected to one end of the transmission shaft 8 via a transmission component. The other end of the transmission shaft 8 passes through the first concave sleeve 4 and extends along the central axis of the filter cylinder 2, i.e., the transmission shaft 8 and the filter cylinder 2 are coaxially arranged. Multiple connecting shafts 9 are evenly distributed around the outer circumference of the transmission shaft 8, and the ends of the multiple connecting shafts 9 are connected to the inner wall of the filter cylinder 2. In this embodiment, four connecting shafts 9 are evenly distributed around the outer circumference of the transmission shaft 8 to form a cross structure. In this embodiment, connecting shafts 9 are provided at both the front and rear ends. During actual operation, when the motor 7 starts to rotate, the transmission shaft 8 and the connecting shaft 9 drive the filter cylinder 2 to start rotating. Simultaneously, since both ends of the filter cylinder 2 are rotatably connected to the first concave sleeve 4 and the second concave sleeve 5 via bearings, the filter cylinder 2 begins to rotate.

[0045] It also includes a spray assembly, which is located inside the housing 1, and is used to clean the filter cartridge 2 to prevent clogging. The spray assembly includes a shower pipe 12 and a water pump 13. The shower pipe 12 is positioned above the filter cartridge 2 and is arranged along the axial direction of the filter cartridge 2. Both ends of the shower pipe 12 are respectively fixedly installed on the top ends of the first concave sleeve 4 and the second concave sleeve 5 on corresponding sides. The outlet of the water pump 13 is connected to the shower pipe 12 via a water supply pipeline, and the inlet of the water pump 13 is connected to a water inlet 1-4, which is located on the top of the housing 1.

[0046] In this embodiment, by setting an angle adjustment mechanism, the tilt angle of the filter cylinder 2 can be adjusted. In conjunction with the rinsing assembly, the filter cylinder 2 can also be effectively rinsed and cleaned, effectively avoiding clogging of the filter cylinder 2 and resulting in a decrease in filtration effect.

[0047] In the above embodiments, preferably, the spiral baffle 3 is arranged along the axial direction of the filter cylinder 2.

[0048] In the above embodiments, preferably, the tilt angle of the guide plate 6 is 10°-30°.

[0049] In this embodiment, by setting an inclined guide plate 6, the filtrate filtered by the filter cylinder 2 can be effectively discharged, reducing mud deposition, ensuring smooth discharge, and improving the overall processing efficiency of the equipment.

[0050] In the above embodiment, preferably, the mud flows into the filter cylinder 2 through the injection port 1-1 and the injection pipe 15. After being filtered by the rotation of the filter cylinder 2, the filtrate is discharged through the filter holes on the surface of the filter cylinder 2 to the bottom guide plate 6, and then collects at the discharge port 1-2 via the guide plate 6, and is discharged outward from the discharge port 1-2. The filtered rock debris in the filter cylinder 2 is transported by the rotating spiral baffle 3 inside the filter cylinder 2, moves to the waste port 14, and flows into the waste hopper 1-3 for collection. In the above embodiment, preferably, after the filtration work is completed, the filter cylinder 2 can be effectively cleaned by the flushing pipe 12 and the water pump 13. During the cleaning process, the filter cylinder 2 can also be adjusted to an inclined state by the hydraulic cylinder 10 and the rotating shaft 11.

[0051] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
