A tapered shear grinding head with a floating stator

Abstract

The invention provides a conical shear grinding head with a floating stator. The shear grinding head comprises a conical rotor (1), a conical stator (2), a flexible stator sleeve (3) and a drive motor (7). The conical rotor (1) is of a conical circular truncated cone structure, the outer conical face of the conical circular truncated cone is provided with a plurality of forwards-inclined feeding slots (4) which are uniformly distributed in the circumferential direction, and the forwards-inclined direction is consistent with the rotation direction of the conical rotor (1); and the center of the conical rotor (1) is provided with a conical positioning hole (5). By means of the conical shear grinding head, simplification of the rotor and stator position fit relationship is achieved, it is guaranteed that edge lines fully intersect, and the precision requirement and the machining cost are lowered. Meanwhile, the conical shear grinding head furthermore has the advantages of being simple and reliable in structure and convenient and fast to disassemble, assemble and clean.

Description

technical field [0001] The invention relates to the technical field of shearing and crushing of a slurry processing method, in particular to a conical shearing grinding head with a floating stator. Background technique: [0002] Crushing is a general operation form, which can reduce the particle size of colloid and solid particles and increase the specific surface area of ​​materials. Dispersing colloid or solid particles in a liquid carrier for crushing can reduce the crushing energy and temperature rise of granular materials. The crushing of pulp is an important form of crushing operations. For the miniaturization of ductile particles in slurry, stator-rotor rotary shear crushing is a widely used efficient crushing method. [0003] The structure of the stator-rotor rotary shearing and crushing device mainly has two forms: cylindrical mating surface and conical mating surface. The representative model of the cylindrical mating surface structure is the homogenizer, and th...

Problems solved by technology

In practice, the rotor rotates at a high speed and the stator needs to be able to adjust the axial position, which causes problems such as complex positioning relationship between the rotor and the stator, low concentricity, and staggered edge lines. The processing cost of the rotor and stator is high, and the shearing efficiency is low.
