Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of Chinese medicinal material processing and relates to an airflow superfine pulverizer for Chinese medicinal materials. Background Art
[0002] The airflow ultrafine pulverizer uses airflow to impact materials, causing them to collide with each other at high speed and be crushed and refined. At present, most airflow ultrafine pulverizers are equipped with multiple air nozzles at the entrance of the material to make the materials refined, collide and move upward. After rising to the position of the sorting wheel, some of the refined materials are discharged, and the materials that cannot be discharged are returned to the air nozzle attachment for further refinement. This method has high requirements on the particle size of the Chinese medicinal materials fed into the feed. Materials with larger particles will remain at the bottom of the crushing chamber because they cannot be refined in time or lifted. The accumulated large particles interfere with the airflow and the mutual collision of other materials. Utility Model Content
[0003] The purpose of the utility model is to provide a Chinese medicinal material airflow superfine pulverizer in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the material pulverizing efficiency.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a Chinese medicinal material airflow ultrafine pulverizer, characterized in that it includes a pulverizing chamber, a feeding screw located at the bottom of the pulverizing chamber, a first air intake manifold and a second air intake manifold, the first air intake manifold is connected in parallel with a plurality of first air nozzles, the second air intake manifold is connected in parallel with a plurality of second air nozzles, the bottom of the pulverizing chamber has a conical material guide head, the large diameter end of the material guide head faces downward, the second air nozzle is located above the first air nozzle, the air outlet of the second air nozzle is tilted downward, and the airflows of the first air nozzle and the second air nozzle both act on the material guide head.
[0005] Furthermore, a sorting wheel and a discharge pipe are arranged on the top of the crushing chamber.
[0006] The material enters the grinding chamber through the feed screw, and the first air nozzle and the second air nozzle form a more chaotic airflow outside the guide head. Moreover, the second air nozzle can impact the material downward to make the large particles at the bottom rise, thus avoiding the problem of some large particles sinking to the bottom. In addition, the airflow path of this method is more diverse, and the airflow grinding efficiency is higher. The existence of the guide head can make the rising materials collide with each other, and can also make the falling materials return to the bottom of the grinding chamber close to the air nozzles.

[0011] The material enters the pulverizing chamber 1 through the feed screw 2, and the first air nozzle 5 and the second air nozzle 6 form a more chaotic airflow outside the guide head 7. Moreover, the second air nozzle 6 can impact the material downward to make the large particles of the material at the bottom rise, thereby avoiding the problem of some large particles of material sinking to the bottom and accumulating. In addition, the airflow path of this method is more diverse, and the airflow pulverizing efficiency is higher. The existence of the guide head 7 can make the rising materials collide with each other, and can also make the falling materials return to the bottom of the pulverizing chamber 1 close to the air nozzles.
[0012] In addition, the presence of the material guide head 7 can improve the heat dissipation in the material crushing area, thereby preventing the Chinese medicinal materials from gelatinizing and agglomerating during the crushing process.
