[0022] The second embodiment: the method of applying the equipment of the first embodiment to break the wall of pine pollen, including the following steps:

[0023] S1. Adjustment and start-up of the initial state of the equipment: close the cleaning valve 5, the air inlet valve 10 and the charging valve 12, open the circulation stop valve 6, start the fan I1, fan II2, and fan III3, and open the air intake valve 10 after the fan is started. The opening degree of the regulating valve 9 is between 5-40%, so that the inside of the grading device 7 and the grading device 8 are in a positive pressure state of 100 Pa to 1000 Pa;

[0024] S2. Feeding: Open the feeding valve 12 to add pine pollen with a moisture content of less than 10%. The amount of pine pollen added is 20% of the volume of the circulation channel. The pine pollen enters the circulation channel under the action of gravity and the negative pressure of the fan, and is Under the action, a fluidized state is formed, and the ...

Abstract

The invention discloses airflow grinding equipment and a wall breaking method with the same for pollen pini. The airflow grinding equipment is characterized in that a circulating channel is formed by a fan (1), a circulating pipeline I (4), a circulating stop valve (6), a grading device (7), a grading device (8), an adjusting valve (9), an air inlet three-way part (11) and a circulating pipeline II (13). The airflow grinding equipment and the wall breaking method disclosed by the invention have the advantages that materials form fluidized state and flows circularly at high speed in the circulating channel, the fluidized materials are ground under the action of a fan impeller, a pipe wall and mutual collision; the equipment is simple in structure, high in grinding efficiency, low in energy consumption and large in yield.

Description

Technical field [0001] The invention relates to a circulating air current crushing device and a method for breaking the wall of pine pollen. Background technique [0002] The working principle of the existing jet mill is that compressed air is sprayed into the crushing cavity pre-loaded with materials at high speed through nozzles, and the materials are repeatedly collided, rubbed, and sheared at the intersection of multiple high-pressure air streams. The crushed materials Under the action of the fan suction, it moves with the upward airflow to the classification device to separate the coarse and fine materials. The fine particles that meet the particle size requirements enter the collection device through the classification device and are collected, and the coarse particles descend to the crushing zone to continue to be crushed. The existing jet mill has a complicated structure and needs to consume a large amount of compressed air. The current pine pollen wall breaking method u...
