[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1: As Figure 1-7 As shown, a drilling mud treatment device with high processing efficiency includes an outer box 1 with a mud pipe 7 fixedly connected to the top. A water collection frame 8 is fixedly connected above the outer box 1. A cleaning support 11 is fixedly connected above the water collection frame 8. A vibrating support 13 is slidably connected to the inner side of the cleaning support 11. A screen 25 is fixedly connected to the inner side of the vibrating support 13. A baffle plate 26 is fixedly connected above the screen 25. A chain support 12 is fixedly connected to the upper side of the cleaning support 11. A drive assembly is movably connected to the inner side of the chain support 12. A scraper support 18 is fixedly connected to the inner side of the drive assembly. Multiple cleaning scrapers 19 are fixedly connected below the scraper support 18. The cleaning scrapers 19 can be inserted between two baffle plates 26.

[0031] The drive assembly includes a drive chain 14, a scraper motor 15, a drive sprocket 16, and a synchronous shaft 17. The drive sprocket 16 is rotatably connected to the inside of the chain bracket 12. The drive chain 14 is driven by the drive sprockets 16 on both sides. The scraper bracket 18 is fixedly connected between the drive chains 14 on both sides. The scraper motor 15 is fixedly connected to one side of the chain bracket 12. The power output end of the scraper motor 15 is fixedly connected to one side of the drive sprocket 16. Two drive sprockets 16 at the same height are fixedly connected by the synchronous shaft 17.

[0032] During operation, mud is sprayed from the mud pipe 7 onto the top of the screen 25. Large particles in the mud are blocked by the top baffle plate 26, and the screen 25 below further blocks smaller rock fragments. The mud that has passed through the screen 25 and baffle plate 26 then enters the next processing step. At the same time, the scraper motor 15 is started, driving the drive chains 14 on both sides to work. This drives the scraper bracket 18 to rotate, allowing multiple cleaning scrapers 19 to pass through the gap in the middle of the baffle plate 26 below, scraping out the rock fragments stuck therein. At the same time, the bottom of the cleaning scrapers 19 can contact the screen 25 to scrape away the rock fragments above the screen 25. By cleaning the screen 25 and baffle plate 26 simultaneously during the mud treatment process without stopping the machine, clogging above the screen 25 can be prevented, ensuring the pass rate of the screen 25 and improving the processing efficiency.

[0033] In this embodiment, a vibration motor 22 is fixedly connected to one end of the vibration bracket 13, and multiple limiting slide rods 23 and springs 24 are fixedly connected to both ends of the vibration bracket 13. The limiting slide rods 23 are slidably connected to the inner side of the cleaning bracket 11, and the drive chain 14 is movably connected to the inner side of the cleaning bracket 11. When the vibration motor 22 is started, it can drive the vibration bracket 13 to move up and down to achieve the vibrating screen effect.

[0034] In this embodiment, a temporary storage box 9 is fixedly connected to the lower end of the water collection frame 8, and a horizontal spiral centrifuge 2 is fixedly connected to the lower inner side of the outer casing 1 of the water pump 10. The inlet of the horizontal spiral centrifuge 2 is fixedly connected to the outlet of the water pump 10.

[0035] The temporary storage tank 9 can temporarily store the filtered slurry, and together with the water pump 10 below, it can stably supply material to the horizontal screw centrifuge 2. The horizontal screw centrifuge 2 can separate the remaining slurry into water and mud cake, thus achieving separation.

[0036] In this embodiment, a drain pipe 4 and a drain pipe 6 are fixedly connected to the bottom of the horizontal spiral centrifuge 2. A dry material box 3 is fixedly connected to the lower end of the drain pipe 4. A stone material pipe 5 is fixedly connected to the top of the dry material box 3. A stone material collection frame 27 is fixedly connected to the top of the stone material pipe 5. The top of the stone material collection frame 27 is fixedly connected to the lower side of the cleaning support 11.

[0037] The dry material bin 3 is used to recover large rock fragments swept down from above and mud cake processed by the horizontal screw centrifuge 2, so as to realize the centralized recycling and processing of mud cake.

[0038] In this embodiment: during use, mud is sprayed from the mud pipe 7 onto the top of the screen 25. Large particles in the mud are blocked by the top baffle plate 26. The screen 25 below further blocks smaller rock fragments. The mud that has been screened by the screen 25 and the baffle plate 26 then enters the next processing step. At the same time, the scraper motor 15 is started, driving the drive chains 14 on both sides to work. This drives the scraper bracket 18 to rotate, allowing multiple cleaning scrapers 19 to pass through the gap in the middle of the baffle plate 26 below, scraping out the rock fragments stuck in it. At the same time, the bottom of the cleaning scraper 19 can contact the screen 25 to scrape away the rock fragments above the screen 25. By cleaning the screen 25 and the baffle plate 26 simultaneously during the mud treatment process without stopping the machine, clogging above the screen 25 can be prevented, ensuring the pass rate of the screen 25 and improving the processing efficiency.

[0039] When the vibration motor 22 starts, it can drive the vibration bracket 13 to move up and down to achieve the vibrating screen effect. The temporary storage box 9 can temporarily store the filtered mud. Together with the water pump 10 below, it can achieve stable feeding to the horizontal screw centrifuge 2. The horizontal screw centrifuge 2 can separate the remaining mud into water and mud cake to achieve separation.

[0040] The dry material bin 3 is used to recover large rock fragments swept down from above and mud cake processed by the horizontal screw centrifuge 2, so as to realize the centralized recycling and processing of mud cake.

[0041] Example 2: A drilling mud treatment device with high processing efficiency. This example is based on Example 1 with the following improvements, such as... Figure 1-7 As shown,

[0042] In this embodiment, a limiting boss 1 20 and a limiting boss 21 are fixedly connected to one side of the chain bracket 12, and the lower side of the limiting boss 1 20 and the upper side of the limiting boss 21 are slidably connected to the drive chain 14.

[0043] The lower side of the limiting boss 1 20 and the upper side of the limiting boss 21 can clamp and restrict the movement trajectory of the drive chain 14. This can prevent the scraper bracket 18 and the cleaning scraper 19 from being squeezed upwards when passing above the screen 25, thus preventing them from achieving the normal scraping effect.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
