when the device works, quartz sand tailings flow into the receiving hopper (12) through the feed hopper (11), water flow sprayed from the water spray nozzle (16) washes soil adhered to the quartz sand, the washed soil, the quartz sand and water form turbid liquid, when the turbid liquid flows through the bottom of the U-shaped pipe (1), circulating water in the washing pipe (2) flows through the water through hole (14), the turbid liquid is continuously diluted, and then mud containing soil is taken away, so that the soil and the quartz sand are well separated; when the quartz sand wrapped with the iron oxide in the suspension flows through the grinding chamber (3), the quartz sand is crushed after being extruded and ground by the grinding chamber (3) and the grinding gear (31), and the quartz sand and the iron oxide wrapped on the quartz sand are ground and separated, so that the subsequent iron oxide separation work is smoothly carried out; under the impact of water flow of the water spray opening (16), the quartz sand particles which are heavy and contain iron oxide flow to the bottom of the U-shaped pipe (1) along with the water flow due to the heavy weight, and the iron oxide is separated by extrusion grinding of the grinding chamber (3) and the grinding gear (31); the fine quartz sand particles without iron oxide are lighter in weight, fall down along with the impact of water flow to the high position of the receiving hopper (12), and flow into one end of the U-shaped pipe (1) far away from the receiving hopper (12) through the separation holes (41), the separation cavity (42) and the communicating pipe (43) due to the obstruction of the separation barrel (4) positioned at the upper part of the connecting part of the separation barrel (4) and the receiving hopper (12), so that the workload of the grinding gear (31) is reduced, the service life of the grinding gear (31) is prolonged, the power consumption of a motor for driving the grinding gear (31) is reduced, and energy is saved; the quartz sand mixed iron oxide which is subjected to mud removal through the water passing holes (14) and is crushed by the grinding gear (31) continuously flows in the U-shaped pipe (1) to push the water wheel (5) to rotate, the water wheel (5) drives a driving wheel through a belt to further drive the conveying belt (51) to rotate, the rotating conveying belt (51) drives the permanent magnet (52) to adsorb the iron oxide on the upper part of the inner wall of the transverse pipe (17), the iron oxide is driven by water flow to flow out of the upper part of the partition plate (18) in the transverse pipe (17) and then is collected, the remaining quartz sand flows out of the transverse pipe (17) below the partition plate (18), and water is filtered and then is recycled; the water wheel (5) rotates to stir the quartz sand and the ferric oxide, so that the suspension state of the quartz sand and the ferric oxide in water is kept, and the separation efficiency of the ferric oxide is further increased; the quartz sand particles extruded by the rotation of the grinding gear (31) are impacted on the air bag (32) and then rebound to the grinding gear (31) to be ground and crushed again, so that the grinding efficiency of the quartz sand particles is increased, the separation effect of the quartz sand and the ferric oxide is further enhanced, the flow rate of suspension at the bottom of the U-shaped pipe (1) can be further increased by the rotating grinding gear (31), and the washing separation speed of slurry in the suspension is further increased; meanwhile, the air bag (32) is impacted and extruded to generate compressed gas, the compressed gas is sprayed out through the pipeline and the air spraying holes (54), rising bubbles are formed in water, quartz sand and iron oxide in the water are further stirred, the suspension state of the quartz sand and the iron oxide in the water is kept, and the separation efficiency of the iron oxide is further increased; water flow sprayed from the water spray nozzle (16) continuously impacts the floating ball (6), the floating ball (6) floating up and down drives the ratchet wheel (55) to rotate through the connecting rope (61), and the ratchet wheel (55) is matched with the pawl (56) to further accelerate the rotating speed of the water wheel (5), so that the suspension state of crushed quartz sand and ferric oxide is further maintained, and the separation efficiency of the ferric oxide is increased.
