Abstract:At present, the intelligent control strategy for the separation process of the heavy-medium cyclone and the parameterization method of the pole group crushing and separation hydrocyclone are limited to single parameter optimization, and it is difficult to control the small size deformation. Based on this problem, a fluent-based cyclone is designed. Controller hierarchical control system. Use switch-type AC stabilized power supply to provide reliable power for the system. Use Q941F electric control ball valve to perform corresponding interval actions. Use BST6800 series pressure transmitter to realize underflow flow control. The top-mounted pneumatic valve switch structure is adopted to enhance the reliability of the valve. Through the man-machine interaction module, display the execution tasks. According to the principle of fluent-based numerical simulation, the diameter of the particles entering the cyclone is calculated. Combining the Gambit model and the meshing method, simulate and analyze the distribution of tangential velocity, lateral velocity and radial velocity in three directions. Two sets of control output are used to adjust the feed speed of the cyclone to obtain the best classification size and ensure the stability of the cyclone classification process. It can be seen from the experimental results that the highest classification efficiency of the system is 98%, and the lowest is 90%, which has a highly efficient classification effect.
