Description

Technical Field

[0001] The utility model relates to the technical field of powder classifiers, in particular to a high-efficiency powder classifier. Background Art

[0002] Powder classifiers are widely used in coal mills, raw material drying mills and cement mill systems in new dry process cement production lines. There are many types of powder classifiers, and different types are suitable for different materials. Different models are also made according to customers' requirements for material fineness. Common powder classifiers include cyclone powder classifiers, three-separation powder classifiers, centrifugal powder classifiers, coal mill special powder classifiers, calcium powder special powder classifiers, etc. Later, many high-efficiency powder classifiers and high-efficiency three-separation powder classifiers were developed.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN213349748U discloses a high-efficiency powder selection machine. The utility model includes a chassis, a dispersion component and a screening component. Two symmetrical feed hoppers are arranged on the top of the chassis, a fine powder discharge pipe is arranged in the middle of the chassis, a coarse powder discharge pipe is arranged at the bottom of the chassis, and a main shaft is arranged inside the chassis, and the bottom end of the main shaft is rotatably connected to the first bearing seat. The utility model is provided with a first dispersion disc, a second dispersion disc, a third dispersion disc, a stepped baffle and dispersion teeth, and the three-stage scattering can thoroughly disperse the materials, thereby improving the subsequent classification efficiency. By providing a first screening blade, a second screening blade and four side screening blades, a composite screening blade is adopted, so that the materials can be stirred more evenly, and the powder selection effect is improved, which solves the problems of the existing powder selection machine with insufficient powder selection efficiency, insufficient material dispersion and unsatisfactory screening effect.

[0004] Although the existing high-efficiency powder classifier improves the powder selection effect, the powder classifier pours cement production materials into the chassis during operation. Therefore, when the cement material feeding flow is not controlled, the materials are poured into the chassis uniformly, which easily increases the energy consumption of the high-efficiency powder classifier and increases the use cost of the high-efficiency powder classifier. At the same time, the cement raw materials are processed in the chassis, and hard materials such as stones in the cement raw materials are easy to cause friction damage to the chassis, reducing the service life of the high-efficiency screening machine structure and reducing the practicality of the high-efficiency screening machine.
