Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, the present invention provides a wastewater impurity filtration device for well repair operations, including a sedimentation tank 1 and a connecting pipe 2. The connecting pipe 2 is fixedly installed on the left side of the top of the sedimentation tank 1. A cleaning port 3 is opened at the bottom of the left side of the sedimentation tank 1. A collection mechanism 4 is fixedly connected to the left side of the sedimentation tank 1, and a filtration mechanism 5 is fixedly connected to the right side of the sedimentation tank 1.

An insert plate 43 is inserted into the inner wall of the slot 42. The top of the insert plate 43 passes through the connecting frame 41 and extends to the top of the connecting frame 41. The insert plate 43 is movably connected to the connecting frame 41.

[0022] As a technical optimization of this utility model, by setting up a collection mechanism 4, solid impurities in the wastewater can settle along the slope plate 9 into the interior of the connecting frame 41. When the solid impurities settle to a certain amount, the user can easily clean the solid impurities by pulling the insert plate 43 upward. The slot 42 can improve the stability of the insert plate 43.

[0023] refer to Figure 2 The filtration mechanism 5 includes a filter box 51, a filter bucket 52 connected to the right side of the sedimentation box 1, the filter bucket 52 is inclined, and an installation plate 53 is fixedly connected to the top of the inner wall of the filter box 51. The right side of the filter bucket 52 is fixedly connected to the left side of the installation plate 53.

[0024] As a technical optimization of this utility model, by setting up a filter mechanism 5, the mounting plate 53 can fix the filter bucket 52. The filter bucket 52 can filter the wastewater entering the filter box 51. The filter bucket 52 is set at an inclination. The solid impurities remaining in the filter bucket 52 can slide along its inner wall to the top of the slope plate 9. Finally, as the wastewater continues to flow from the limiting plate 8 to the slope plate 9 and the filter bucket 52, the solid impurities can be gradually moved to the inside of the connecting frame 41.

[0025] refer to Figure 2 A connecting bracket 6 is fixedly connected to the right side of the mounting plate 53. The connecting bracket 6 is L-shaped, and an activated carbon plate 7 is fixedly installed on the inner wall of the connecting bracket 6.

[0026] As a technical optimization of this utility model, by setting a connecting frame 6 and an activated carbon plate 7, the connecting frame 6 can fix and limit the activated carbon plate 7, and the activated carbon plate 7 can adsorb oil stains in wastewater.

[0027] refer to Figure 2 A limiting plate 8 is fixedly connected to the left side of the inner wall of sedimentation tank 1, and a slope plate 9 is fixedly connected to the right side of the bottom of the inner wall of sedimentation tank 1.

[0028] As a technical optimization of this utility model, by setting a limiting plate 8 and a slope plate 9, the limiting plate 8 can prevent wastewater entering the sedimentation tank 1 from directly impacting the solid impurities settled at the bottom of the sedimentation tank 1, causing the solid impurities to surge. The slope plate 9 can guide the solid impurities sliding down in the filter hopper 52.

[0029] refer to Figure 1 The bottom of the sedimentation tank 1, the filter tank 51 and the connecting frame 41 are fixedly connected to the bottom of the base plate 10, and the four corners of the bottom of the base plate 10 are fixedly installed with casters 11.

[0030] As a technical optimization of this utility model, by setting a base plate 10 and a moving wheel 11, the base plate 10 can support the sedimentation tank 1, the filter tank 51 and the connecting frame 41, and the moving wheel 11 makes it convenient for the user to move the whole device.

[0031] refer to Figure 2 The bottom right side of the filter box 51 is connected to the water outlet pipe 12. The top of the limiting plate 8 is fixedly connected to two reinforcing plates 13. The left side of the two reinforcing plates 13 is fixedly connected to the left side of the inner wall of the sedimentation box 1.

[0032] As a technical optimization of this utility model, by setting the water outlet pipe 12 and the reinforcing plate 13, the wastewater filtered by the activated carbon plate 7 can be discharged from the inside of the filter box 51 through the water outlet pipe 12, and the reinforcing plate 13 can improve the stability of the limiting plate 8.

[0033] The working principle and usage process of this utility model are as follows: When it is necessary to filter the wastewater generated by well repair operations, first connect the connecting pipe 2 to the output end of the external water pump body, and then start the water pump body to transport the wastewater to the interior of the sedimentation tank 1. At this time, some solid impurities in the wastewater can settle to the bottom of the inner wall of the sedimentation tank 1. At the same time, the filter bucket 52 can filter the wastewater entering the filter box 51. The filter bucket 52 is set at an inclination. The solid impurities remaining in the filter bucket 52 can slide along its inner wall to the top of the slope plate 9. As the amount of solid impurities increases and the wastewater continues to flow from the limiting plate 8 to the slope plate 9 and the filter bucket 52, the solid impurities can gradually move to the interior of the connecting frame 41. The activated carbon plate 7 can adsorb the oil stains in the wastewater entering the filter box 51 from the filter bucket 52. Finally, the wastewater can be discharged from the filter box 51 through the outlet pipe 12 for easy discharge by the user. When the solid impurities settle to a certain amount, the user can easily clean the solid impurities inside the connecting frame 41 by pulling the insert plate 43 upward.

[0034] In summary, this wastewater impurity filtration device for well workover operations, through the cleaning port 3, allows solid impurities such as sand and gravel in the wastewater entering the sedimentation tank 1 to settle at the bottom of the sedimentation tank 1. The user can easily clean it through the cleaning port 3. This solves the problem that a large amount of wastewater containing oil, sand, and solid particles is generated during well workover. If it is directly discharged or reinjected, it will not only pollute the environment but may also clog the formation and affect the subsequent mining efficiency.
