Description

A kind of ultrafine pulverizer

technical field

The invention relates to a material dispersing machine, in particular to an ultrafine pulverizer.

Background technique

In the chemical industry, dispersion engineering has always been an important part. Such as coatings, paints, inks, dyes, printing, pesticides, etc. must use dispersion engineering. The original various stirring pulverizers mostly use dispersion blades or The high-speed rotation of the rod pin and the grinding action of the grinding medium cause the particles in the slurry to be subjected to forces such as impact, friction, grinding and shearing, so as to realize the dispersion and grinding of the particle material. However, due to the large grinding space, the dispersing blade or The centrifugal force generated by the rotation of the bar pin is limited, so that the grinding medium is easy to deposit when it is still. The bottom of the cylinder is not easy to start, and the beads are fragile, which greatly weakens the shear force between the material and the grinding medium. At the same time, the motor drives the dispersion shaft to rotate in one direction. , resulting in insufficient dispersion of materials, resulting in low efficiency, high energy consumption, and unsatisfactory dispersion effect.

Contents of the invention

Aiming at the problems of low efficiency, high energy consumption and unsatisfactory dispersion effect of existing pulverizers, the present invention provides an ultrafine pulverizer, which can powerfully grind and disperse materials, has better grinding particle size, and can produce efficient.

There are stirring rods, rotating arms, crushing disc I, and crushing disc II. At least two of the rotating arms are evenly installed on the axial ring surface of the main shaft. The lower end of the rotating arm is equipped with a crushing medium. The medium is in the form of a ring gear, and the inner wall of the cylinder is equipped with a ring gear corresponding to the gear on the pulverized medium.

It is further characterized in that: the rotating arm is in an inverted L shape;

At least two of the stirring rods are evenly installed on the axial ring surface of the main shaft, and each of the stirring rods is equipped with round rods arranged in a staggered manner;

The outer peripheral surface of the crushing disc I is evenly equipped with crushing rods I, and at least one kidney groove is opened on the crushing disc I;

The crushing disc II is installed at the bottom end of the main shaft, and at least one crushing rod II is installed on the upper and lower end faces of the outer edge of the crushing disc II, and the crushing rods II on the upper and lower end faces are arranged correspondingly , at least one small hole is opened on the crushing disc II;

The outer wall of the cylinder is provided with a cooling cavity, and the outside of the cooling cavity is provided with a water inlet and a water outlet connected thereto; the top of the cylinder is provided with a material inlet, and the bottom of the cylinder is provided with an outlet feed port.

The beneficial effect of the present invention is that after the material is dispersed at high speed in the cylinder by the stirring rod and the round rod, it is crushed and ground by the rotating arm with the high-speed revolution of the main shaft and the ring-shaped gear-type crushing medium that can rotate by the ring gear, and the obtained Large compression force and shearing force, finally the material is crushed by the crushing disc Ⅰ and crushing disc Ⅱ, so that the material is subjected to speed difference to form a turbulent flow movement, and a strong grinding and dispersing effect is obtained, and the particles become more fine. Fine and uniform, so it has better grinding particle size and high production efficiency.

Detailed ways

As shown in Figures 1 to 5, the present invention includes a motor 1. After the motor 1 is connected to the reducer 2, it is connected to one end of the main shaft 3 extending into the cylinder 16 through a coupling, and the main shaft 3 in the cylinder 16 is installed in sequence. There are stirring rod 5, rotating arm 6, crushing disc I14, crushing disc II12, eight rotating arms 6 are evenly installed on the axial ring surface of the main shaft 3, and the rotating arms 6 are inverted L-shaped; the lower end of each rotating arm 6 The crushing medium 10 is sleeved with the bearing 11, the crushing medium 10 is in the shape of an annular gear, and the inner wall of the cylinder 16 is equipped with a ring gear 7 corresponding to the gear on the crushing medium 10, and the ring gear type crushing medium 10 can be mounted on the ring gear 7. Rolling; six stirring rods 5 are evenly installed on the axial ring surface of the main shaft 3, and each stirring rod 5 is equipped with round rods 4 arranged alternately; eight crushing rods are evenly installed on the outer ring surface of the crushing disc I14 Ⅰ15, there are four kidney grooves 20 on the crushing disc Ⅰ14 to increase the crushing shear force; Rod II13, and the crushing rods II13 on the upper and lower end faces of the outer edge of the crushing disc II12 are arranged correspondingly, or the crushing rods II13 on the upper and lower end faces can also be arranged in a staggered manner, which can be set according to the situation.

The present invention is a pulverizer whose pulverization principle and structure are totally different from the existing agitating type pulverizers. This device does not use ball or glass-like pulverization media, but uses many high-speed revolving and self-rotating ring-shaped gears. Pulverize the medium 10, and obtain a strong force (centrifugal force) that cannot be obtained by pulverizing the medium (ball, glass bead) with a traditional pulverizer, and then apply a large compressive force and shear force to the material through this force, which has the advantages of Good grinding particle size, high production efficiency; its specific working process is that the material enters the cylinder 16 from the upper feeding port 19 of the cylinder 16, and passes through 6 evenly distributed stirring rods 5 and the staggered stirring rods on each stirring rod 5.
