How to improve the working efficiency of hydrocyclones? It has always been a concern of everyone. The hydrocyclone in the fine sand recovery machine is also called a sediment separator. The hydrocyclone is the core component of the fine sand recovery machine. The hydrocyclone is achieved by centrifugal sedimentation. The purpose of grading sediment is that the fine sand is centrifuged, classified, and concentrated by the hydrocyclone, and then discharged into the dewatering screen through the sand settling nozzle for dehydration, so as to realize the separation of sediment. The following cyclone manufacturers introduce how to improve the working efficiency of hydrocyclones.
The production capacity of the hydrocyclone increases with the increase in inlet pressure; under the same inlet pressure, the use of a center rod can increase the production capacity of the hydrocyclone by more than 12%, and the solid content of the underflow is also significantly increased; When the center rod is inverted, the hydrocyclone is significantly improved in terms of adaptability to inlet pressure and underflow clamping.
In view of the problems of air column and underflow pinching in the operation of hydrocyclones in thermal power plants, the inverted cone center rod is designed to eliminate the air column and improve the working performance of the hydrocyclones. The experimental method was used to analyze the changes in the performance of the hydrocyclone under different inlet pressures, and the production capacity of the centerless rod, cylindrical center rod, and inverted cone center rod pair, underflow concentration, underflow solid content, and gypsum particle distribution in underflow slurry were obtained Impact. The results show that compared with the non-center rod, the use of the inverted cone center rod can increase the production capacity by 18%, increase the underflow solid content by 22%, and the classification performance has good adaptability to the inlet pressure, and can effectively relieve the underflow clamp Fine phenomenon.
Hydrocyclones are affected by many aspects in production, but the pressure is a very important factor. The pressure is mainly affected by the frequency of the pump, so more directly it should be the pump, and then the nature and concentration of the slurry Fineness, as well as the cyclone itself, dust nozzle, dust nozzle after a long time, the discharge opening becomes larger, which has a great influence on the pressure, in fact, the cyclone is very important in the beneficiation, and controls the fineness of the entire ball mill .
