One end of the third connecting rod 8 is rotatably connected to a fourth connecting rod 9. A filter screen 10 is provided at one end of the fourth connecting rod 9. The fourth connecting rod 9 is rotatably connected to the fixed box 1. The staff starts the first motor 2 to drive the first rotating shaft 3 to rotate, drives the fourth connecting rod 9 to rotate reciprocally on the fixed box 1, and drives the filter screen 10 to swing reciprocally. Open the valve 29, the fracturing fluid flows out from the liquid flow pipe 24 and passes through the filter screen 10, and flows into the collection barrel 21. The solid suspended matter and the hardly degradable substances in the fracturing fluid can be filtered out through the filter screen 10. Through the reciprocating swing of the filter screen 10, the solid suspended matter and the hardly degradable substances can effectively slide off from the filter screen 10, which greatly improves the working efficiency.

[0030] A fixing plate two 12 is fixedly connected to a fixing plate one 11. A motor two 13 is fixedly connected to the fixing plate two 12. An output end of the motor two 13 is fixedly connected to a rotating shaft three 14. A bevel gear one 15 is fixedly connected to the rotating shaft three 14. A rotating shaft four 16 is rotatably connected to the fixing plate one 11. A bevel gear two 17 is provided on the rotating shaft four 16. The bevel gear two 17 meshes with the bevel gear one 15. A circular gear 18 is fixedly connected to one end of the rotating shaft four 16. A limiting plate 22 is provided on the rotating shaft four 16. A connecting ring 20 is fixedly connected to the limiting plate 22. A collecting bucket 21 is fixedly connected to the connecting ring 20. An internal gear 19 is fixedly connected to the connecting ring 20. The internal gear 19 meshes with the circular gear 18. A liquid flow pipe 24 penetrates and is connected to a containing bucket 23. A supporting column one 25 is fixedly connected to a lower end of the containing bucket 23. A supporting column two 26 is fixedly connected to a lower end of the fixing box 1. A universal wheel 27 is fixedly connected to one end of the supporting column two 26. A valve 29 is provided on the liquid flow pipe 24. There are four groups of the supporting column one 25 and four groups of the supporting column two 26. A worm gear 5 rotates inside the fixing box 1. The circular gear 18 is arranged between the collecting bucket 21 and the limiting plate 22. A filter screen 10 is located above the collecting bucket 21. The liquid flow pipe 24 is arranged above the filter screen 10. The fixing box 1 is located on one side of the collecting bucket 21. The bevel gear one 15 is arranged below the limiting plate 22. The staff starts the motor two 13 to drive the connecting ring 20 to drive the collecting bucket 21 to rotate at a high speed. Through the high-speed rotation of the collecting bucket 21, the oil stain and the liquid in the fracturing fluid can be separated. After rotating at a high speed for a certain period of time, the motor two 13 is stopped. At this time, the oil stain will float on the surface of the fracturing fluid, and the staff can fish it out, which can improve the treatment effect of the oil stain in the fracturing fluid and also improve the work efficiency.

[0031] Working principle: First, the staff stores the fracturing fluid in the storage barrel 23. At this time, the staff moves the fixed box 1 to one side of the collection barrel 21 through the universal wheels 27 provided under the fixed box 1, and at the same time moves the filter screen 10 above the collection barrel 21 and below the liquid flow pipe 24. Then the staff starts the first motor 2 to drive the first rotating shaft 3 to rotate. Through the fifth rotating shaft 28 provided, the first rotating shaft 3 drives the worm gear 5 to rotate in the fixed box 1. Through the second rotating shaft 4 eccentrically arranged on the worm gear 5, the first connecting rod 6 is driven to make a reciprocating circular motion. The first connecting rod 6 drives the second connecting rod 7 and the third connecting rod 8 to make a reciprocating circular motion, and drives the fourth connecting rod 9 to reciprocally rotate on the fixed box 1, and drives the filter screen 10 to reciprocally swing. At this time, the staff opens the valve 29, so that the fracturing fluid in the storage barrel 23 flows out from the liquid flow pipe 24, passes through the filter screen 10, and flows into the collection barrel 21. The solid suspended matter and refractory substances in the fracturing fluid can be filtered out through the provided filter screen 10. Through the reciprocating swing of the filter screen 10, the solid suspended matter and refractory substances can effectively slide off the filter screen 10. The dropped impurities are cleaned by the staff, which greatly improves the work efficiency. When the fracturing fluid in the storage barrel 23 has flowed out, the staff closes the valve 29, and pushes the fixed box 1 through the universal wheels 27 to move the filter screen 10 out of the upper part of the collection barrel 21. At this time, there will be oil stains remaining in the fracturing fluid filtered by the filter screen 10. Then the staff starts the second motor 13 to drive the third rotating shaft 14 and the first bevel gear 15 to rotate. The first bevel gear 15 drives the second bevel gear 17 to rotate, and drives the fourth rotating shaft 16 to rotate on the first fixing plate 11. The fourth rotating shaft 16 drives the circular gear 18 to rotate. The circular gear 18 drives the internal gear 19 to rotate. The internal gear 19 drives the limiting plate 22 to rotate on the fourth rotating shaft 16, and makes the connecting ring 20 drive the collection barrel 21 to rotate at a high speed. Through the high-speed rotation of the collection barrel 21, the oil stains remaining in the fracturing fluid in the collection barrel 21 make a centrifugal separation movement with the liquid, so that the oil stains and the liquid in the fracturing fluid can be separated. When the high-speed rotation lasts for a certain period of time, the second motor 13 is stopped, and at this time the collection barrel 21 stops. At this time, the oil stains will float on the surface of the fracturing fluid and are fished by the staff, which can improve the treatment effect of the oil stains in the fracturing fluid and also improve the work efficiency.
