Abstract

The invention relates to the technical field of emulsifying equipment, and concretely relates to an impeller and a low-noise emulsifying pump. The impeller comprises a stator and a rotor coupled withthe stator, and at least one shear blade of the rotor and / or at least one tooth blade of the stator are / is provided with a pressure reduction channel. When a fluid is homogenized, sheared and emulsified by the stator and the rotor which are coupled with each other, the shear blade of the rotor passes through the inner and outer layers of the tooth blade of the stator, the pressure reduction channel communicates the fluid on the two sides of the shear blade and / or the fluid on the two sides of the tooth blade, the pressure difference of the fluid on the two sides of the shear blade and / or the tooth blade is reduced, squeal generated during homogenizing, shearing and emulsifying is eliminated, and friction of the material with the rotor and the stator is reduced, so sound generated when thehomogenizing and shearing emulsifying pump works is reduced.

Description

technical field [0001] The invention relates to the technical field of emulsification equipment, in particular to an impeller and a low-noise emulsification pump. Background technique [0002] The emulsification pump is a precise combination of rotor and stator, which generates strong shearing force in high-speed rotation to achieve mixing, homogenization, dispersion, and crushing. The emulsification pump can be used for continuous emulsification or dispersion of multi-phase liquid media, and at the same time, it can transport low-viscosity liquid media. It can also realize continuous mixing of powder and liquid in proportion. Widely used in daily chemical, food, medicine, chemical industry, petroleum, paint, nanomaterials and other fields. The emulsification pump includes a stator and a rotor. When the fluid is homogenized, sheared, and emulsified through the coupled rotor and stator, the friction and impact of the material with the rotor and stator are relatively loud, t...
