Liquid classifier for colloid mill

Abstract

The invention discloses a liquid classifier for a colloid mill, which comprises a classifier shell, a finished product discharge pipe and a classification mechanism, one end of the finished product discharge pipe is inserted from the bottom of the classifier shell and extends upward; the classifier The lower end of the side wall of the shell is provided with a back grinding outlet; the classification mechanism includes a speed-regulating motor and a classifier rotating piece, and the classifier rotating piece is sleeved outside the finished product discharge pipe; the upper end of the classifier rotating piece is connected to the The speed-regulating motor is connected, and the speed-regulating motor can drive the rotary plate of the classifier to rotate about the axis of the finished product discharge pipe. A liquid classifier for colloid mills of the present invention utilizes classifier rotating blades to rotate materials, so that materials of different thicknesses can be stratified at different speeds, and coarser materials flow back to the colloid from the back grinding outlet. The mill continues to grind, and the materials that meet the requirements enter into the finished product discharge pipe from the leakage hole, which is convenient and quick.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a liquid classifier for colloid mills. Background technique [0002] Colloid mill is a commonly used dispersion grinding equipment in food, chemical, pharmaceutical, building materials and other industries, especially for architectural coating manufacturers, which often use colloid mill to grind materials. [0003] The main part of the traditional colloid mill is composed of housing, stator, rotor, adjustment mechanism, cooling mechanism, motor and so on. The shell is provided with a hopper, and the bottom of the shell is provided with two passages, a material discharge port and a material return port. Usually, when grinding materials, put the materials into the colloid mill filling hopper, close the discharge port, start the motor, and the materials start to grind, and the materials are pumped from the return port to the filling funnel while grinding, and flow into the filling funnel.
