Device for Preparing Polymer Powder
The invention relates to the technical field of pulverizers, in particular to a preparation
device of polymer powder.
In the processing and use of polymer materials, it is often necessary to smash them before
use. Using the dispersibility and processability of polymer powders, it is possible to realize
the compounding of polymer powders with different functions, thereby designing,
researching, and manufacturing high-performance and functional new materials. At
present, as the application field of polymer powder becomes extensive, the requirements
for its particle size and particle size distribution are also increasingly higher. The current
pulverizer can smash some common polymer materials, such as plastic products based on
polypropylene (PP), polyvinyl chloride (PVC), etc. However, there are deficiencies in the
smashed products such as large particle size and wide distribution range. Besides, it cannot
meet the smashing requirements of special polymer materials such as polyphenylene
sulfide (PPS), polyimide (PI), and polyether ether ketone (PEEK). It is much more difficult
to carry out ultrafine comminution of fibers or rubber products.
In addition, the particle size of current device is usually over 100 microns, which cannot
meet the requirements of high-performance structural materials, display devices, high-end
fillers and coatings, new functional materials and other new process materials (such as 3D
printing raw materials). Therefore, it is urgent to develop a device for preparing ultrafine
polymer powder which can prepare high-quality ultrafine polymer powder with average particle size less than 50 microns or even less than 10 microns, so as to meet the needs of new functional materials and structural materials.
The purpose of the invention is to provide a device for preparing polymer powder.
The technical scheme adopted by the invention is described below.
A device for preparing ultrafine polymer powder is disclosed in the invention, which
specifically comprises a smashing chamber, two driving motors, a base, a classification
impeller, a cyclone separator, a bag filter, a blower, an induced draft fan and a plumbing
installation. The blower is connected to the bottom of the side wall of the smashing
chamber and the bottom of the smashing chamber is provided with a base. Besides, the first
driving motor is installed inside the base. A connecting shaft is arranged inside the
smashing chamber, which passes through the outer wall of the smashing chamber and is
connected with the rotating shaft of the driving motor. The connecting shaft is provided
with a pulverizing blade. On the side wall of the smashing chamber, a feed inlet is arranged.
The top of the smashing chamber is equipped with a classification impeller, which is
connected with the second driving motor below. The classification impeller is further
connected to the cyclone separator through a pipe, and the air outlet of the cyclone separator
is connected to the bag filter.
The basic principle of the invention is as follows. The principle of strong shear
comminution is adopted, and the high-speed rotating blade generates a strong shear
comminution force field, so that the polymer material is rapidly smashed and refined in the
smashing chamber. The refined sample is driven by the air flow to the classification impeller. After separation by the classification impeller, the large particle material falls back to the smashing chamber and is smashed again. The qualified fine powder enters a cyclone separator along with airflow and is separated from air, then is discharged from a discharge port as finished product.
Compared with the existing technology, the invention has following obvious advantages.
1. After being smashed, the polymer material of the invention is sorted by a classification
impeller, so that the uniformity of product granularity can be improved.
2. The airflow from the cyclone separator is dedusted by the bag filter, which improves the
product yield and reduces the dust pollution to the environment.
3. The device of the present invention is multifunctional, which can be used for ultrafine
comminution of plastic polymer materials, as well as ultrafine comminution of fiber and
rubber polymer materials.
4. The device is simple to operate and easy to realize engineering amplification.

according to the present invention.

realize the quantitative transportation of materials.
