[0004] However, in actual use, the above-mentioned scheme still has some deficiencies. Drilling construction under different geological conditions produces mud of different properties, and the particle size, viscosity and other characteristics of the mud are different. The fixed mesh size of the mud filter screen cannot adapt to the diversified mud filtering requirements, resulting in unsatisfactory filtering effect. Either the filtered mud still contains a lot of impurities, or the filtering speed is too slow, affecting the construction progress. Moreover, as the drilling construction deepens, the content and types of impurities in the mud will change. If the mud filter screen with the appropriate mesh size cannot be replaced in time, the filtering device will be clogged and the abrasion will be aggravated, which not only affects the filtering efficiency, but also shortens the service life of the filtering device.

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] Example 1, such as Figs. 1-3 As shown, a folded mud filtration system includes a first folded groove 1, a first sedimentation tank 3, a second sedimentation tank 9, and a mud tank 14. A through hole 2 is provided on the right side of the first folded groove 1. A fourth limiting groove 16 is provided inside the first folded groove 1 on the side away from the through hole 2. A fourth filter plate 17 is inserted into the fourth limiting groove 16. Slots 4 are provided on the opposite sides and right sides of the first sedimentation tank 3 and the second sedimentation tank 9. The left side of the first folded groove 1 engages with the right side slot 4 of the first sedimentation tank 3. A second folded groove 5 is connected between the first sedimentation tank 3 and the second sedimentation tank 9 via the slots 4. The interior of the folded groove 5 is provided with a first limiting groove 6, and the interior of the second folded groove 5 is provided with a second limiting groove 7. A first filter plate 8 is inserted into both the first limiting groove 6 and the second limiting groove 7. A third folded groove 10 is inserted into the right side slot 4 of the second sedimentation tank 9. The right side of the third folded groove 10 is connected to the interior of the mud tank 14. The interior of the third folded groove 10 is provided with two third limiting grooves 11 that are symmetrically distributed on the left and right sides. A second filter plate 12 is inserted into the left third limiting groove 11, and a third filter plate 13 is inserted into the right third limiting groove 11.

[0022] The right side of the first folding groove 1 is drilled to form a through hole 2 by a drilling machine, and mud is introduced into the first folding groove 1 through the through hole 2, filtered for the first time by the fourth filter insert plate 17, then introduced into the first sedimentation tank 3, and the continuously rising mud is introduced into the second folding groove 5, filtered for the second time by two first filter insert plates 8, then introduced into the second sedimentation tank 9, and the continuously rising mud is introduced into the third folding groove 10, filtered again by the second filter insert plate 12 and the third filter insert plate 13, then introduced into the mud tank 14, and the cooperation of the first folding groove 1, the first sedimentation tank 3, the second folding groove 5, the second sedimentation tank 9 and the third folding groove 10 prolongs the filtering path of the mud and enhances the filtering effect.

[0023] In example 2, further improvements are made on the basis of example 1, and the specific improvements are as follows: The bottom of the mud tank 14 is fixedly installed with a mud pump 15 in communication with the inside of the mud tank 14.

[0024] The filtered mud is pumped out by the mud pump 15, and the filtered mud reduces the wear and tear of the accessories of the mud pump 15, avoids the replacement of parts, prolongs the service life, and reduces the expenditure.

[0025] In example 3, further improvements are made on the basis of example 1, and the specific improvements are as follows: The mesh number of the fourth filter insert plate 17 is smaller than that of the first filter insert plate 8.

[0026] The fourth filter insert plate 17 only performs preliminary filtration on the mud, and cooperates with the first sedimentation tank 3 to perform sedimentation treatment.

[0027] In example 4, further improvements are made on the basis of example 1, and the specific improvements are as follows: The mesh number of the first filter insert plate 8 is the same as that of the second filter insert plate 12.

[0028] The first filter insert plate 8 and the second filter insert plate 12 simultaneously have a filtering effect, so that part of the impurities in the second sedimentation tank 9 cannot enter the third folding groove 10 through the second filter insert plate 12, facilitating subsequent filtration.

[0029] In example 5, further improvements are made on the basis of example 1, and the specific improvements are as follows: The mesh number of the first filter insert plate 8 and the second filter insert plate 12 is smaller than that of the third filter insert plate 13.

[0030] The third filter insert plate 13 with a large mesh number can filter out smaller particles, and plays a finishing role in the entire filtration system, improving the overall filtration effect.

[0031] Embodiment 6, this embodiment is a further improvement on the basis of embodiment 1, which is as follows: the second filter insert plate 12 is consistent in height with the third filter insert plate 13.

[0032] When two second filter insert plates 12 and third filter insert plates 13 with different mesh numbers and consistent in height are used in the same third folding groove 10, a multi-level filtering system can be formed and the overall filtering effect can be improved.

[0033] Although the embodiments of the present application have been shown and described above, it should be understood that the above-mentioned embodiments are exemplary and should not be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and modifications to the above-mentioned embodiments within the scope of the present application.
