Problems solved by technology

[0003] The existing powder classifier has low efficiency and high energy consumption, and because the rotor is in a state of high-speed operation for a long time, the rotor blades on it are in contact with the powder, which is easy to be eroded and worn, which greatly limits its service life and needs to be improved urgently

Abstract

The invention relates to the technical field of mechanical equipment, in particular to a high-efficiency low-energy-consumption powder concentrator. A middle shell is arranged on the lower portion of an upper shell, a discharging shell is arranged on the lower portion of the middle shell, and a finished product discharging pipe is arranged on the lower portion of the discharging shell. The upper shell is provided with a feed inlet and a motor, the motor is connected with a rotor through a spindle, stators are arranged outside the rotor, and the rotor and the stators are both arranged in the middle shell. A coarse material receiving hopper is arranged in the discharging shell, and the bottom of the coarse material receiving hopper is connected with a coarse material discharging pipe. A stator blade is connected to the inner wall of each stator through a stator shaft; twenty-four rotor blades are connected to the rotor; the motor is a variable frequency motor; the surface of each rotor blade is subjected to wear-resistant treatment through wear-resisting solder wires, and the included angle alpha between each stator blade and the tangent line of the inner circle of the corresponding stator ranges from 125 degrees to 135 degrees. Powder concentrating efficiency is high, energy consumption is low, and the service life of the powder concentrator is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a powder separator with high efficiency and low energy consumption. Background technique [0002] The powder separator is widely used in coal mills, raw meal unloading drying mills and cement mill systems in cement production lines. It can be divided into three categories: three-separation separator, centrifugal separator and cyclone separator. There are many types of powder separators, and different types are suitable for different materials. Different models are also made according to the customer's requirements for material fineness. Commonly used powder separators include cyclone separator, three-separation separator, centrifugal separator, special separator for coal mill, special separator for calcium powder, etc. Later, many high-efficiency powder concentrators and high-efficiency three-separation powder concentrators were developed. They are new-generation v...
