Five distributors 11 are provided in the overflow chamber 4, and the five distributors 11 are evenly spaced from front to back. The distributors 11 are used to evenly transport the slurry to the discharge port 7 and the sampling chamber 9. The cyclone When the ore pulp transported by the pipeline enters the feed chamber 3 from the feed port 5, the ore pulp impacts the baffle 2, and the baffle 2 slows down the impact force of the ore pulp. Subsequently, the ore pulp in the feed chamber 3 flows from the gap between the baffle 2 and the bottom of the main body 1 to the overflow chamber 4. At this time, the ore pulp in the overflow chamber 4 is located on the left side of the overflow slope 6. As the ore pulp in the overflow chamber 4 increases, the ore pulp overflows from the top of the overflow slope 6 to the left side of the overflow slope 6, and a part of the ore pulp on the left side of the overflow slope 6 is evenly introduced into the discharge port 7 through the distributor 11, and another part of the ore pulp on the left side of the overflow slope 6 is evenly introduced into the sampling chamber 9 through the distributor 11, and the sampling The slurry in the sample chamber 9 is then discharged from the return port 10 for recovery.
