Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of powder depolymerization, and particularly relates to a spiral powder depolymerization machine. BACKGROUND

[0002] Micron powder with a particle size of 1-100 mu m will appear agglomeration and other phenomena under the action of van der Waals force after drying or long-term storage, which seriously affects its use function. Therefore, special equipment is needed to depolymerize it to restore it to its original particle morphology.

[0003] The traditional particle depolymerization method is mostly dry knocking depolymerization method, which is easy to cause over-pulverization of particles, resulting in poor operation effect and waste of a large amount of materials. The existing depolymerization machine on the market adopts the principle of centrifugal impact pulverization, but its volume is relatively large, the equipment cost is high, and due to the classification principle, the depolymerization efficiency is low and the precision is poor, which affects the overall equipment efficiency and energy consumption, and is easy to cause dust pollution. Therefore, the existing technology cannot meet the requirements of high quality, high efficiency and pollution-free depolymerization operation of agglomerated powder. SUMMARY

By designing multiple gas-solid pipelines and cross-shaped cutters installed at different angles, the agglomerated powder can be uniformly depolymerized, and the depolymerized powder is collected by the powder collection bag through the discharge port. The working environment of the depolymerization pipeline is a closed environment, which greatly avoids dust pollution caused by dust raising. In terms of driving, high-speed airflow generated by the air compressor provides power, energy loss is small, depolymerization efficiency is high, and the gas-solid pipeline is connected by the connecting mechanism, which is easy to disassemble and convenient for later maintenance and maintenance.
