The cover plate is fixedly installed on the upper surface of the filter box, and a vibration mechanism is provided inside the filter box. A stirring mechanism is provided on the upper surface of the cover plate. This patent uses a stirring mechanism to dilute the drilling mud with water before filtration, preventing the drilling mud from becoming too sticky and causing blockages during filtration.

[0027] Example 1

[0028] A high-efficiency drilling mud filtration device, such as Figures 1 to 3 As shown, the system includes a filter box 1, a dilution cylinder 2 on the top of the filter box 1, and a connection between the filter box 1 and the dilution cylinder 2 via a solenoid valve. Inside the filter box 1, a filter plate 3 is fixed by a connecting assembly. The filter plate 3 slides against the inner wall of the filter box 1. A vibration motor is installed on the bottom outer wall of the filter plate 3. The filter box 1 has a discharge port. The end of the filter plate 3 near the discharge port is inclined towards the ground. A telescopic rod 8 is installed on the top outer wall of the filter box 1. The telescopic end of the telescopic rod 8 is fixedly connected to a sealing plate 6 via a fixing rod 7. The sealing plate 6 is sealed against the inner wall of the discharge port. A guide hopper 5 is fixed to the side wall of the discharge port.

[0029] The top outer wall of the dilution cylinder 2 is provided with a feeding pipe and a water injection pipe. A drive motor 12 is installed on the top outer wall of the dilution cylinder 2. A stirring rod 11 is rotatably connected to the inner wall of the dilution cylinder 2. The output shaft of the dilution cylinder 2 is connected to the rotating shaft of the stirring rod 11. A scraper 13 is fixedly connected to the side wall of the rotating shaft of the stirring rod 11 through a fixing component. The scraper 13 is in contact with the inner wall of the dilution cylinder 2. A discharge port 10 is provided at the bottom of the filter box 1.

[0030] The connecting assembly includes multiple connecting rods 4 and a spring 9. The multiple connecting rods 4 are fixed at both ends of the top of the filter plate 3. The outer wall of the connecting rod 4 is vertically slidingly engaged with the filter box 1. The top of the connecting rod 4 is provided with a threaded hole 14. The inner wall of the threaded hole 14 is threadedly connected to a limit block 15. The spring 9 is sleeved on the outer wall of the connecting rod 4. The two ends of the spring 9 are respectively connected to the limit block 15 and the filter box 1.

[0031] All electrical components in this solution are electrically connected to the controller, which can be a conventional known device such as a computer. All electrical components are powered by an external circuit.

[0032] In use, the slurry is injected into the dilution cylinder 2 through the feeding pipe, and water is injected into the dilution cylinder 2 through the water injection pipe. The drive motor 12 drives the stirring rod 11 to rotate, diluting the slurry. Then, the solenoid valve opens, and the diluted slurry enters the filter box 1 and falls onto the filter plate 3. The scraper 13 rotates with the stirring rod 11, scraping off the slurry adhering to the inner wall of the dilution cylinder 2. The vibration motor drives the filter plate 3 to vibrate, and the connecting rod 4 and spring 9 provide guidance for the vibration of the filter plate 3. The slurry is filtered through the filter plate 3. After filtration, the telescopic rod 8 pushes and fixes the filter plate 3. When rod 7 moves, the sealing plate 6 disengages from the discharge port. The stones and other materials filtered out on the filter plate 3 are discharged from the discharge port, guided by the guide bucket 5, and fall into the collection box placed below the guide bucket 5. At the same time, the slurry is diluted in the dilution cylinder 2. When spring 9 has problems such as elasticity decay and needs to be replaced, the limiting block 15 can be rotated and unscrewed. At this time, spring 9 can be pulled upwards, and then the new spring 9 can be put on the connecting rod 4. Then the limiting block 15 is connected to the threaded hole 14 to complete the replacement of spring 9.

[0033] With the help of a guide hopper 5, a sealing plate 6, a fixing rod 7 and a telescopic rod 8, the stones and other particles filtered out on the filter plate 3 can be automatically discharged from the outlet after filtration, without the need for manual cleaning.

[0034] With the threaded hole 14 and the limiting block 15, the spring 9 can be quickly replaced when problems such as elasticity decay occur, making the operation convenient.

[0035] Example 2

[0036] A high-efficiency drilling mud filtration device is provided in this embodiment, which is based on Embodiment 1 and makes the following improvements, such as... Figure 4 As shown, the fixing assembly includes a connecting cylinder 16 and a compensating rod 17. The connecting cylinder 16 is fixed to the side wall of the rotating shaft of the stirring rod 11. The compensating rod 17 is laterally slidably fitted to the inner wall of the connecting cylinder 16. One end of the compensating rod 17 is provided with an annular protrusion. A second spring 18 is sleeved on the outer wall of the compensating rod 17. One end of the second spring 18 is connected to the inner wall of the connecting cylinder 16, and the other end is connected to the annular protrusion.

[0037] When filter plate 3 wears out after long-term use, spring 2 18 drives compensation rod 17 to move relative to connecting cylinder 16. Compensation rod 17 pushes scraper 13 to fit against the inner wall of dilution cylinder 2 to compensate for the wear of filter plate 3.

[0038] By setting a fixing component, when the filter plate 3 wears out after long-term use, the scraper 13 is pushed to fit against the inner wall of the dilution cylinder 2 to compensate for the wear of the filter plate 3 and ensure the cleaning effect of the filter plate 3 on the inner wall of the dilution cylinder 2.

[0039] Working principle: During use, slurry is injected into dilution cylinder 2 through the feeding pipe, and water is injected into dilution cylinder 2 through the water injection pipe. The drive motor 12 drives the stirring rod 11 to rotate, diluting the slurry. Then, the solenoid valve opens, and the diluted slurry enters the filter box 1 and falls onto the filter plate 3. The scraper 13 rotates with the stirring rod 11, scraping off the slurry adhering to the inner wall of the dilution cylinder 2. The vibration motor drives the filter plate 3 to vibrate. The connecting rod 4 and spring 9 provide guidance for the vibration of the filter plate 3. The slurry is filtered through the filter plate 3. After filtration, the telescopic rod 8 pushes the fixed rod 7 to move, and the sealing plate 6 disengages from the discharge port. The stones and other particles filtered out on the filter plate 3 are discharged from the discharge port. After being guided by the guide bucket 5, the mud falls into the collection box placed below the guide bucket 5, while the mud is diluted in the dilution cylinder 2. When the spring 9 needs to be replaced due to problems such as elasticity decay, the limit block 15 can be rotated and unscrewed. At this time, the spring 9 can be pulled upward, and then the new spring 9 can be put on the connecting rod 4. Then the limit block 15 is connected to the threaded hole 14 to complete the replacement of the spring 9. When the filter plate 3 wears out after long-term use, the spring 18 drives the compensation rod 17 to move relative to the connecting cylinder 16. The compensation rod 17 pushes the scraper 13 to fit against the inner wall of the dilution cylinder 2 to compensate for the wear of the filter plate 3.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
