Quartz sand steady flow type hydraulic classifier

The utility model discloses a quartz sand steady flow type hydraulic classifier which comprises a cylinder body and a thickness classification chamber which are communicated up and down, a feed port is arranged at the center of the top end of the cylinder body, an overflow groove is arranged on the side face of the top of the cylinder body, and an ore discharge port is arranged at the bottom end of the thickness classification chamber. The water inlet turbulence pipe is arranged at the bottom of the thickness grading chamber and horizontally arranged, and a set of water spray nozzles are arranged on the water inlet turbulence pipe. The quartz sand steady-flow type hydraulic classifier is reasonable in structural design, after an original turbulent flow plate is replaced with the turbulent flow pipe, a uniform and stable laminar flow fluidized bed in the horizontal direction and a uniform and stable settling layer with coarse particles in the vertical direction are formed in the coarse and fine classification
