Description

[0001] Air current type crusher [0002]

The present invention relates to an air stream type pulverizing apparatus.

In general, pulverization of grains is mainly performed by impulsive pulverization for pulverizing raw materials by directly impacting the raw materials, or freezing pulverization for pulverizing raw materials through a coolant such as liquid nitrogen and embrittling them.

However, in the impact type pulverization method, when the quality of the pulverized product deteriorates due to a large heat generated by the impact, or when the oil content is large, the pulverized product is deformed into an oil state by oil and is not pulverized.

In addition, the freeze-crushing method requires a large amount of expensive liquid nitrogen or the like, which increases the running cost and requires a large facility investment to cool the crusher itself.

Accordingly, in order to solve the above problems, a conventional air flow type milling method has been developed in which air is crushed through collision between raw materials on an air stream.

The air stream type pulverization method can suppress the heat generation due to a small impact due to the collision between the raw materials through the air stream and can efficiently pulverize the raw material having a high oil content into fine particles. There is an advantage that cost can be suppressed.

However, in the conventional air stream type pulverizing method described above, when the rotating blades provided in the casing and generating airflow are provided on both sides of the rotating shaft in the form of a single blade so that the particles are substantially unbalanced, There is a problem that the airflow that can generate sufficient impact can not be generated and the particles of the raw material can not be evenly pulverized.

Further, in the conventional air stream type pulverization method, the inclined surface formed inside the casing is positioned adjacent to the front surface of the rotary vane for classifying the pulverized particles so that the substantially pulverized pulverized material is sufficiently moved along the inner surface of the casing, Size and weight of the particles, and the particles are discharged to the outside of the casing by the airflow without discrimination according to the particle size.

That is, the guide portion 1711a may protrude outward from the upper end of the charging portion 1711. Therefore, when the raw material is charged, the charged raw material is vertically dropped into the loading portion 1711 of the hopper 171 and can be moved toward the loading portion 1711 along the inclined inner surface of the guide portion 1711a without falling. As a result, a large amount of raw material is vertically dropped instantaneously, and a tubular shape extending downward from the charging portion 1711 is formed by momentarily moving a large amount of the raw material vertically by moving a large amount of raw material sequentially toward the charging portion 1711 side along the inner surface of the guide portion 1711a. It is possible to prevent a phenomenon of clogging the discharge portion 1713 of the ink cartridge.

That is, as the rotary shaft 1751 rotates, the raw material introduced into the inlet portion 1711 through the inclined inner surface of the guide portion 1711a is guided to the mixing portion 1753 rotating around the inner surface of the inlet portion 1711 ), Or they may be mixed in an even state without being concentrated.

A large amount of the raw material mixed by the mixing portion 1753 does not flow directly into the discharge portion 1713 at one time and is indirectly discharged through the inclined surface 1755a of the overflow prevention member 1755, (1713), so that they can be introduced into the discharge portion (1713) sequentially by a certain amount.

Illustratively, the overflow preventing member 1755 is a plate-like member protruding outward from the rotating shaft 1751, and an inclined surface 1755a may be formed on the upper side.

Therefore, the raw material moves primarily along the inclined inner surface of the guide portion 1711a and does not drop vertically but stably enters the loading portion 1711, and is uniformly discharged through the rotation of the mixing portion 1753 And is indirectly introduced into the interior of the discharge portion 1713 through the inclined surface 1755a of the inflow preventing member 1755 in a final (tertiary) manner, thereby being stably transferred to the body portion 13.

Illustratively, the conveying device 1773 provided inside the induction pipe 1771 may be a conveyor-type device for conveying an object. That is, the conveying device 1773 may be a screw conveyor device having a structure similar to the conveying screw 175, or a belt conveyor device for conveying an object by rotating the belt. However, the transfer device 1773 is not limited to this, and can be replaced with a configuration that performs the same function as needed for use.

Finally, the control unit 173 can control the driving of the conveying screw 175 and the conveying unit 1773 provided inside the conveying unit 177. [

The control unit 173 includes a control module (not shown) therein so as to control the power unit 179 coupled to the rotary shaft 1751 of the conveying screw 175 and the conveying unit 1773, respectively can do. Accordingly, the user can change the supply condition of the raw material through the control unit 173 by controlling the operation time or rotation speed of the feed screw 175 and the feed screw 1773 according to the raw material of the raw material.
