Hydrocyclone

Fluid cyclone is a common separation and classification equipment, and the principle of centrifugal sedimentation is commonly used. When the two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent flow occurs. Due to the size difference between coarse particles and fine particles, they are subject to centrifugal force, centripetal buoyancy, fluid drag, etc., and are subject to centrifugal sedimentation. Most of the coarse particles are discharged through the bottom flow port of the cyclone, while most of the fine particles are discharged by The overflow pipe is discharged to achieve the purpose of separation and classification.

Hydrocyclone operation method

1. Before starting the test run, make sure that all the connection points of the cyclone unit are tightened, and remove all kinds of residues in the pipes and the unit box to avoid leakage and blockage after start-up. Make sure the cyclone valve is fully open when it is put into operation.
2. The valve may be fully open (e.g. operating cyclone) or fully closed (e.g. standby cyclone), but must never be left half-open (i.e. the valve must never be used to control flow).
3. If possible, test the car with clean water first. The feed to the cyclone can be provided by pump or high-level tank. If the pump is matched to the cyclone throughput, the pressure gauge will show a constant reading. Make sure that the pressure gauge reading does not fluctuate. If there is significant fluctuation, check the cause. The equipment is required to work at a pressure no higher than 0.3MPa.
4． When the equipment is running smoothly under normal pressure, check the amount of leakage at the connection points and take remedial measures if necessary.
5. Check for clogging caused by debris entering the cyclone. The blockage of the cyclone feed port will reduce the overflow and sand settling flow, and the blockage of the cyclone sand settling port will reduce the sand settling flow or even cut off the flow, and sometimes violent vibrations will occur. If blockage occurs, the cyclone feeding valve should be closed promptly and the blockage should be cleared. In order to prevent clogging, facilities (such as chip removal screens) can be added to the feed tank of the hydrocyclone group to prevent coarse materials and debris. At the same time, the feed tank should be emptied in time when parking to avoid sedimentation and debris when starting the machine again. Excessive concentration may cause clogging accidents.
6. When the equipment is proven to be running well by the clean water test, it can be fed with slurry for operation.
