During use, in the centrifugal process, the rotation speed of the main motor 16 is gradually increased, along with the increase of the rotation speed of the main motor 16, the centrifugal force received by the gravity ball 317 is gradually increased, then the gravity ball 317 drives the connecting rod 316 to overcome the elasticity of the spring III 318 to swing outwards, along with the rising of the gravity ball 317 driving the rotating rod, the sliding area of the gravity ball 317 is increased, finally the connecting rod 316 collides with the side surface of the stop lever 315, the stop lever 315 is impacted and then drives the turntable 312 to rotate, the protruding rod 314 slides in the inside of the arc hole 313, and the inner wall of the arc hole 313 extrudes the protruding column to the outer side of the turntable 312.
The centrifugal mechanism 3 further comprises a sliding panel 307, a squeezing plate 308, a flow hole 309, a fixing plate 310 and a rubber sheet 311, wherein the sliding panel 307 is slidably connected to the top of the inner wall of the rotating frame 301, one end of the sliding panel 307, which is far away from the main motor 16, penetrates through the inner wall of the rotating frame 301 and is fixedly connected to the side surface of the squeezing plate, the flow hole 309 is formed in the side surface of the squeezing plate 308, the fixing plate 310 is fixedly connected to one side, which is close to the sliding panel 307, of the squeezing plate 308, the rubber sheet 311 is fixedly connected to the side surface of the fixing plate 310, the rubber sheet 311 is slidably connected to the side surface of the centrifugal groove 304, and the side surface of the rubber sheet 311 is blocked at the one-way valve 306 on the side surface of the centrifugal groove 304.
In use, during the gradual lifting of the gravity ball 317, the drilling fluid in the centrifugal tank 304 is flowed into the outer side of the rotating frame 301 through the flow holes 309, because the weight of the impurity particles is large and the centrifugal force is also large, the solid particles are tightly attached to the inner side wall of the rotating frame 301, thereby realizing solid-liquid layering, after the rotating disc 312 rotates, the convex rod 314 drives the sliding panel 307 and the extrusion plate 308 to slide on the inner wall of the centrifugal tank 304, and finally the extrusion plate 308 slides to the inner wall of the centrifugal tank 304 and extrudes the impurity in the centrifugal tank 304, thereby increasing the effect of solid-liquid layering, meanwhile, before the extrusion plate 308 does not move, the rubber sheet 311 blocks the one-way valve 306, and meanwhile, the friction force is utilized to offset the pulling force of the extrusion plate 308 on the sliding panel 307 after the centrifugal force is applied, thereby preventing the extrusion plate 308 from sliding on its own, after the extrusion plate 308 slides, the rubber sheet 311 is removed, and the drilling fluid after layering flows into the water storage tank 305 through the one-way valve 306.
The drilling fluid is poured into the filter cartridge 12 from the feeding plate 14, then the drilling fluid is filtered by the filter mechanism 2 in the filter cartridge 12 and enters the centrifugal cartridge 11, after the centrifugal cartridge 11 is centrifuged, the staff takes out the separated solids through the first discharge port 13 and the second discharge port 17
With the rotation of the main motor 16, the output end of the main motor 16 drives the convex disc 205 to start rotating, after the convex disc 205 rotates, the convex disc 205 is extruded by the rugged bottom to drive the sliding plate 201 to slide, when the sliding plate 201 slides downwards, the rubber plate and the drill bit 204 move downwards simultaneously, if the drill bit 204 encounters the arch plate 210 during the movement, the rubber plate can deviate due to extrusion, so that the sliding plate 201 is prevented from moving downwards, and the drill bit 204 can drill into the filter holes of the first filter screen 208 and the second filter screen 209 along with the downward movement and clear the filter holes.
After the drilling fluid slides down the feeding plate 14 to the first filter screen 208 and then passes through the second filter screen 209, impurities and water flow in the drilling fluid can impact the first filter screen 208 and the second filter screen 209, the first filter screen 208 and the second filter screen 209 can be extruded to extrude the second spring 212, the second spring 212 starts to shake after being extruded, and vibration of the first filter screen 208 and the second filter screen 209 can be mutually transmitted through the transmission rod 213, so that the vibration amplitude is increased, in the vibration process of the first filter screen 208 and the second filter screen 209, the upper surface and the lower surface of the first filter screen 208 and the second filter screen 209 can extrude the first rotating plate 214 and the second rotating plate 215, and the first rotating plate 214 and the second rotating plate 215 are extruded to generate bending to match the vibration of the first filter screen 208 and the second filter screen 209.

In the process that the gravity ball 317 is gradually lifted, the drilling fluid in the centrifugal tank 304 is flowed into the outer side of the rotating frame 301 through the flowing hole 309, because the weight of the impurity particles is large and the centrifugal force is also large, the solid particles are tightly attached to the inner side wall of the rotating frame 301, thereby realizing solid-liquid layering, after the rotating disc 312 rotates, the convex rod 314 drives the sliding panel 307 and the pressing plate 308 to slide on the inner wall of the centrifugal tank 304, finally the pressing plate 308 is slid to the inner wall of the centrifugal tank 304 and presses the impurity in the centrifugal tank 304, thereby increasing the effect of solid-liquid layering, meanwhile, before the pressing plate 308 does not move, the rubber sheet 311 blocks the one-way valve 306, and simultaneously, the friction force is utilized to offset the pulling force of the pressing plate 308 on the sliding panel 307 after the pressing plate 308 is slid, the rubber sheet 311 is removed, and the drilling fluid after layering flows into the water storage tank 305 through the one-way valve 306.
