[0024] In this embodiment, a sealing ring 22 is provided inside the opening 2 and at the junction of the second liquid outlet pipe 17 and the top cover 3 .

[0025] In this embodiment, the filter cartridge 10 includes a cartridge body 10-1, the bottom of the cartridge body 10-1 is a conical structure, the liquid outlet pipe 11 is arranged at the bottom of the cartridge body 10-1, the top of the cartridge body 10-1 is detachably provided with a cartridge cover 10-2, the liquid inlet pipe 12 is arranged at the top of the cartridge cover 10-2, a partition 10-3 is arranged in the middle of the cartridge body 10-1, a docking sleeve 10-4 is arranged in the middle of the partition 10-3, the bottom end of the filter cartridge 10 is threadedly connected with the docking sleeve 10-4, an annular mounting groove 10-5 is arranged on the bottom surface of the cartridge cover 10-2 at a position corresponding to the filter element 13, a sealing ring 22 is arranged in the annular mounting groove 10-5, a plurality of liquid leakage holes 10-6 are penetrated on the partition 10-3, and the filter element 13 is a hollow structure.

[0027] The working principle and beneficial effects of the above technical solution are: When in use, the oil enters the cyclone desander 14 from the feed pipe 15, and the flow meter constantly detects the flow rate of the oil and transmits the flow rate data to the control processor in real time. In this embodiment, when the flow rate of the oil is lower than 8 m / s, the control processor first controls the electric control valve 15 to close, and opens the electric control valve 29, and then controls the telescopic rod 120-1 to extend, so that the rotating section 14-2 and the conical section 14-3 are separated, and the oil flows directly from the rotating section 14-2 through the discharge pipe 28 into the filter cartridge 10, and the oil passes through the filter element 13. The oil is filtered and flows out from the outlet pipe 11. During maintenance, the filter element 13 is removed for cleaning or replacement to ensure the filtering effect. When the flow rate of the oil is lower than 8m / s, the control processor first controls the electric control valve 15 to open and closes the electric control valve 29, and then controls the telescopic rod 120-1 to contract, so that the rotating section 14-2 and the conical section 14-3 are combined, and the solid particles in the oil follow the oil at a certain speed from the feed pipe 15 into the cyclone desander, forming a strong rotation movement in the tank body and generating centrifugal force. Since the density of the solid particles is greater than the density of the oil, under the action of centrifugal force, the solid particles are quickly thrown to the inner wall of the cyclone desander and move downward in a spiral with the oil near the wall. As the water flows into the conical section 14-3, the rotation radius gradually decreases and the centrifugal force further increases, so that the sand particles adhere more closely to the tank wall and accelerate to move to the bottom. When the solid particles accumulate to a certain extent on the inner wall of the cyclone desander, they automatically fall out from the sand outlet 18 due to the action of gravity and are discharged through the sand outlet 7 provided at the lower end of the sand storage tube 6. While the solid particles are separated and discharged, the purified oil forms an inner vortex, gradually converges to the central area of ​​the cyclone desander, and flows out through the central liquid outlet pipe 17.

[0028] Compared with the prior art, the present invention provides a filter cartridge 1 and a detachable rotating section 14-2 and a conical section 14-3, so that when the oil flow rate is low, it is filtered through the filter element of the filter cartridge 1. When the flow rate reaches the use condition, the cyclone desander is used to remove sand, thereby ensuring the sand removal effect. The solid particles filtered out by the present invention can be discharged by replacing or cleaning the filter cartridge 1 and discharged from the sand discharge port 7 respectively, and will not remain in the machine body, does not require complicated disassembly and maintenance, and is easy to use. Embodiment 2

[0029] like Figure 5-6As shown, in the present embodiment, a filter cartridge 23 is further arranged above the separation cartridge 1, the filter cartridge 23 comprises a cylinder body 23-1, a filter element 23-2 is arranged in the middle of the cylinder body 23-1, the filter element 23-2 is a cylinder structure with a lower end opening 2, the lower end of the filter element 23-2 is detachably connected to the liquid outlet pipe 2 17, the outer wall of the cylinder body 23-1 is connected to an air pipe 1 23-3, the other end of the air pipe 1 23-3 is connected to the air supply device, a barometer is arranged on the cylinder body 23-1 for detecting the air pressure value in the cylinder body 23-1, the liquid outlet pipe 2 17 is located in the cylinder body 23-1 and an air pipe 25 is arranged below the filter element 23-2, an electric control valve 4 26 is arranged on the air pipe 25, a liquid outlet pipe 3 23-6 is arranged on the top of the cylinder body 23-1, and an electric control valve 5 23-5 is arranged on the liquid outlet pipe 3 23-6.

[0030] In this embodiment, an annular material receiving groove 23 - 4 is provided at the inner bottom of the second filter element 23 - 2 .

[0031] The working principle and beneficial effects of the above technical solution are: During use, after the oil after sand removal flows out from the second outlet pipe 17, it enters the second filter cylinder 23, is filtered twice through the second filter element 23-2, and flows out from the third outlet pipe 23-6, thereby further reducing the content of solid particles in the oil. After a period of use, when the filter element 2 needs to be maintained, first close the electric control valve 3 16, close the electric control valve 2 9, close the electric control valve 1 5, close the electric control valve 5 23-5, open the electric control valve 4 26, and then supply air to the cylinder body 23-1 through the air supply device, and observe in real time through the barometer. When the air pressure reaches the preset value, close the electric control valve 4 26, and open the electric control valve 1 5. As the air pressure in the filter element 2 drops sharply, under the action of the internal and external pressure difference, the solid particles attached to the filter element 2 23-2 fall off and are finally discharged from the sand discharge port 7. The filter element 2 of the present invention can be maintained without disassembly, and the operation is simple and convenient, thereby improving the use efficiency. Embodiment 3

[0033] In this embodiment, the area of ​​the central hole of the annular baffle 31 is larger than the area of ​​the sand outlet 18 provided at the bottom of the cyclone desander 14 .

[0034] The working principle and beneficial effects of the above technical solution are: In this embodiment, the opening and closing of the flap 28 is controlled by controlling the extension and retraction of the telescopic rod 29, thereby controlling the opening and closing of the bottom of the separation cylinder 1. Compared with using a valve, in this embodiment, the top surface of the flap 28 can be flush with the bottom of the separation cylinder 1, thereby reducing the accumulation of oil at the bottom of the separation cylinder 1, thereby making the oil filtration more thorough and avoiding losses.
