[0024] ​The collection mechanism is equipped with a filter mechanism for filtering crude oil. The filter mechanism includes a filter cylinder 10, which is located inside the collection cylinder 5. A first connecting rod 11 is provided at the bottom of the filter cylinder 10. The end of the first connecting rod 11 away from the filter cylinder 10 is connected to the inner wall of the first bearing 6. A second connecting rod 13 is provided at the top of the filter cylinder 10. The second connecting rod 13 is hollow. The end of the second connecting rod 13 away from the filter cylinder 10 extends through the collection cylinder 5 to the inner wall of the second bearing 9. A filter hole 14 is provided on the outer wall of the filter cylinder 10 and communicates with the interior of the filter cylinder 10. A flow-damping plate 15 is provided inside the filter cylinder 10. A flow-diverting plate 16 is provided inside the filter cylinder 10 and is located above the flow-damping plate 15.

[0025] The top of the collection mechanism is equipped with a power mechanism to accelerate the filtration speed; the power mechanism includes a first belt reel 17, which is located above the collection cylinder 5 and connected to the second connecting rod 13. The top of the outer casing 3 is equipped with a mounting block 19, and the top of the mounting block 19 is equipped with a motor 20. The output end of the motor 20 is equipped with a second belt reel 21, which is engaged with the output end of the motor 20 by a limit key 22. A belt 23 is sleeved on the surface of the first belt reel 17 and connected to the second belt reel 21.

[0026] A liquid inlet mechanism for crude oil and cleaning water is provided above the power mechanism. The liquid inlet mechanism includes an oil inlet pipe 24, which is located above the first pulley 17 and extends into the interior of the second connecting rod 13. A first flange 25 is provided on the side of the oil inlet pipe 24 away from the first pulley 17. A first valve 26 is provided above the oil inlet pipe 24. A water inlet pipe 27 is provided above the first pulley 17 and extends into the interior of the second connecting rod 13. A second flange 28 is provided at the end of the water inlet pipe 27 away from the first pulley 17. A second valve 29 is provided above the water inlet pipe 27.

[0027] The bottom of the collection mechanism is equipped with an oil discharge mechanism for discharging filtered oil; the oil discharge mechanism includes an oil outlet pipe 30, which is located at the bottom of the funnel 8. A third flange 18 is provided at the end of the oil outlet pipe 30 away from the funnel 8, and a third valve 12 is provided above the oil outlet pipe 30.

[0028] In summary, its working principle can be described as follows:

[0029] The first flange 25 connects to the crude oil output pipe of the oil well. Opening the first valve 26 allows crude oil to enter the filter cylinder 10 through the inlet pipe 24. Turning on the motor 20 drives the second belt pulley 21 to rotate. The rotation of the second belt pulley 21 is transmitted to the first belt pulley 17 via the belt 23, which in turn drives the second connecting rod 13 to rotate, thus rotating the filter cylinder 10. After entering the filter cylinder 10, the crude oil is divided by the diverter plate 16. The rotation of the filter cylinder 10 utilizes centrifugal force to separate the oil and gravel. The separated crude oil flows out through the filter holes 14 into the collection cylinder 5. From the bottom of the collection cylinder 5, it flows into the funnel 8 through the through hole 7. Opening the third valve 12 allows the filtered oil to flow out through the outlet pipe 30. The third flange 18 is used to connect a metal hose, thereby transporting the filtered oil to the storage tank.

[0030] When cleaning is required, the second flange 28 is used to connect the water pipe. Open the second valve 29 to allow pure water to enter the inlet pipe 27 to flush the inside of the filter cylinder 10, causing the sand and gravel inside the filter cylinder 10 to fall to the bottom of the filter cylinder 10. Because the filter cylinder 10 is equipped with a flow-damping plate 15, due to the special structure of the flow-damping plate 15, the sand and gravel will still be at the bottom of the filter cylinder 10 during the next crude oil separation. It is only necessary to determine a time period based on the sand and gravel content of the crude oil on site, open the top of the collection cylinder 5, remove the filter cylinder 10, and flush the inside.

[0031] 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 these 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.
