Description

Technical Field

[0001] This utility model relates to the field of drilling fluid filtration technology, specifically to a drilling fluid sample analysis and filtration device. Background Technology

[0002] Drilling fluid, also known as drilling mud, is composed of a base liquid and various additives. When analyzing drilling fluid samples, it is necessary to separate solid particles such as drill cuttings, clay, and sand from the liquid so that the drilling fluid can be analyzed separately.

[0003] The publication number CN219539645U discloses a filtration device for drilling fluid sample analysis, including a stirring tank with an open top, a drilling fluid discharge valve connected and fixed to the bottom right side of the stirring tank, and a U-shaped seat embedded and fixed on the bottom inner wall of the stirring tank.

[0004] The aforementioned filtration device can facilitate the convenient connection and separation of drilling fluid filtration components. However, during filtration, the filtered impurities can easily clog the filter holes of the filter cover, making it inconvenient to clean. Furthermore, it is not convenient to simultaneously agitate the drilling fluid during cleaning. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Example 1

[0024] Combination Figures 1-4 A drilling fluid sample analysis and filtration device includes a tank 1, a drain valve 2 installed at the bottom of the tank 1, a filter assembly 3 installed inside the tank 1, and a positioning assembly 4 installed outside the tank 1.

[0025] See Figure 2 Furthermore, the filter assembly 3 includes a top cover 5, which is installed on the top of the tank 1. A rotating cylinder 6 is movably installed on the inner ring of the top cover 5. A filter cover 7 is fixedly installed inside the rotating cylinder 6. An adjusting bolt 8 is movably installed through the top of the filter cover 7. A guide post 9 is movably installed at the bottom of the adjusting bolt 8. A motor 10 is installed at the bottom of the tank 1. A shaft 11 is fixedly installed at the top of the output shaft of the motor 10. A transmission groove 12 is opened at the top of the shaft 11. Several stirring paddles 13 are installed on the outside of the shaft 11.

[0026] The rotating drum 6 is located on the inner ring of the top cover 5 and is movably rotating. The opening of the filter cover 7 extends through the bottom end of the rotating drum 6. The drilling fluid inside the rotating drum 6 is filtered through the filter cover 7, and the filtered drilling fluid enters the tank 1 through the bottom end of the filter cover 7.

[0027] The adjusting bolt 8 is threaded through the top of the filter cover 7. The bottom end of the adjusting bolt 8 is connected to the guide post 9 by a bearing. The guide post 9 has a rectangular cross-section. The adjusting bolt 8 drives the guide post 9 to slide downward through the thread.

[0028] The bottom end of the guide post 9 is tapered, and the guide post 9 is snapped into the transmission groove 12. The shaft 11 drives the rotating drum 6 to rotate, so that the impurities filtered by the outer wall of the filter cover 7 are separated to the inner wall of the rotating drum 6 under the action of centrifugal force.

[0029] Specifically, the drilling fluid is filtered through the filter cover 7, the guide column 9 is inserted into the transmission groove 12, and the shaft 11 drives the stirring paddle 13 to rotate to stir the drilling fluid while driving the rotating drum 6 to rotate. This causes the impurities filtered on the outer wall of the filter cover 7 to be separated to the inner wall of the rotating drum 6 under the action of centrifugal force, so as to facilitate the rapid cleaning of the outer wall of the filter cover 7.

[0030] Example 2

[0031] See Figure 3Furthermore, based on Embodiment 1, the positioning component 4 includes four locking blocks 14 and four positioning seats 17. The four positioning seats 17 are fixedly installed on the outside of the tank body 1 near the top. The four locking blocks 14 are fixedly installed on the outside of the top cover 5. A handle 15 is fixedly installed on the top of the top cover 5. Fastening bolts 16 are connected through the interior of two of the locking blocks 14. Positioning holes 18 are opened on the inner walls of the four positioning seats 17.

[0032] The four locking blocks 14 and the four positioning seats 17 are all arranged in a ring. The locking blocks 14 are located inside the positioning seats 17 and are locked together. The top cover 5 is located on the top of the tank body 1 and is positioned by locking the locking blocks 14 and the positioning seats 17.

[0033] The fastening bolt 16 is threaded through the inside of the locking block 14. The inner end of the fastening bolt 16 is engaged with the positioning hole 18. The fastening bolt 16 slides inward through the thread and engages with the positioning hole 18, thereby improving the fixation of the top cover 5.

[0034] Specifically, the locking block 14 is inserted into the positioning seat 17, and the fastening bolt 16 slides inward under the action of the thread and is locked into the corresponding positioning hole 18 for fixation, preventing the top cover 5 from rotating and detaching, so as to facilitate the disassembly and assembly of the rotating drum 6.

[0035] In actual operation, the filter cover 7 is used to filter solid particles such as clay and sand in the drilling fluid. The filtered impurities are located in the rotating drum 6, and the filtered drilling fluid is located in the tank 1. The stirring paddle 13 is used to prevent sedimentation. The drilling fluid is taken out for testing and analysis by opening the discharge valve 2.

[0036] During filtration, the rotating drum 6 is installed inside the tank 1. Drilling fluid is added into the rotating drum 6 and filtered through the filter cover 7. The filtered drilling fluid enters the tank 1 through the bottom of the filter cover 7. When there are many impurities filtered on the outer wall of the filter cover 7, the adjusting bolt 8 is rotated. The adjusting bolt 8 drives the guide column 9 downward through the thread. The guide column 9 is automatically aligned and locked into the transmission groove 12 through the cone at the bottom. The motor 10 is started and the shaft 11 drives the stirring paddle 13 to rotate to stir the drilling fluid and prevent sedimentation. At the same time, the rotating drum 6 is rotated through the guide column 9, so that the impurities filtered on the outer wall of the filter cover 7 are separated to the inner wall of the rotating drum 6 under the action of centrifugal force, so as to facilitate the quick cleaning of the outer wall of the filter cover 7. The rotating drum 6 is removed to facilitate the cleaning of impurities inside the rotating drum 6.

[0037] When positioning and fixing, the top cover 5 is installed on the top of the tank body 1, so that the four locking blocks 14 are respectively locked into the four positioning seats 17. The two fastening bolts 16 are rotated, and the fastening bolts 16 slide inward under the action of the threads and are locked into the corresponding positioning holes 18 for fixing, so as to prevent the top cover 5 from rotating and falling off, so as to facilitate the disassembly and assembly of the rotating drum 6.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
