Abstract

PURPOSE:To enhance crushing efficiency and to make difficult to receive affection of the falling speed of solid substance by forming a crushing edge in the moving blade of a power mill into a plurality of vertical modes. CONSTITUTION:In a power mill for crushing solid substance falling by a moving blade 1 rotated around an axis of rotation, a plurality of crushing edges 6 are arranged side by side in the moving blade 1 so that the directions of these edges becomes the direction parallel to the axis of rotation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power mill, and more particularly to a power mill for crushing solid matter and granules (hereinafter referred to as solid matter).

[0002]

2 is a conceptual side sectional view of a conventional power mill, and FIG. 3 is an enlarged top view showing the rotary blades of FIG.

In FIG. 2, 1 is a rotary blade fixedly arranged on a rotary shaft 8 which rotates around a rotary shaft 8 by an electric motor 2, 2 is a charging port for charging a solid 2a, and 4 is a casing of a power mill Y. It is the body (case).

Further, in FIG. 3, 3 is a crushing blade,
It is arranged on the rotary blade 1, and its blade direction X1 is a single blade perpendicular to the rotary shaft 8. Two blades are arranged on one rotary blade 1 to crush the solid matter 2 (FIG. 2). It is a blade. Reference numeral 5 is a shaft hole that penetrates the rotary shaft 8 (FIG. 2) and fixes the rotary blade 1.

Next, the operation of this conventional example will be described with reference to FIGS. 2 and 3. 2 and 3, the solid matter 2a charged from the solid matter charging port 2 of the power mill 4 spontaneously falls inside the power mill 4 and is crushed by the crushing blades 3 arranged on the rotary blades 1 during this natural fall. It

[0006]

However, in the above-mentioned conventional example, as shown in FIG. 3, the crushing blades 3 arranged on the blade 1 are blades provided singly on both sides of the rotary blade 1. Since the blade direction X1 is perpendicular to the rotation axis 8, there is a very small chance of crushing (cutting) the falling solid matter 2a, and there is a problem that the crushing effect cannot be obtained so much.

Further, there is a problem that the higher the falling speed of the solid material 2a, the less the chance of cutting.

The present invention has been made to solve the above problems, and an object thereof is to increase the crushing chance and improve the crushing efficiency of a power mill.

[0009]

Therefore, according to the present invention, in a power mill having a rotary blade rotating about a rotary shaft and crushing solid matter falling by the rotary blade, the blade is provided on the rotary blade. It is an object of the present invention to achieve the above object by a power mill in which a plurality of crushing blades whose directions are parallel to the rotation axis are provided in a row.

[0010]

With the crushing blades arranged in a row on the rotary blades of the power mill of the present invention with the blade direction parallel to the rotation axis, the chance of impact between the crushing blade and the falling solid matter increases, and the crushing chance increases.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a rotary blade of a power mill according to an embodiment of the present invention. FIG. 1 (a) is a top view of the rotary blade, and FIG. 1 (b) is viewed from an arrow X direction in FIG. 1 (a). It is a figure which shows the broken crushing blade. In the figure, the same reference numerals as those of the conventional example indicate the same or corresponding portions, and the duplicated description will be omitted.

In FIG. 1, 6 is a crushing blade, and a plurality of crushing blades (in this case, 16 on both sides in this case) are formed on the rotary blade 1 in a direction parallel to the rotation axis (perpendicular to the paper surface in FIG. 1A). Sheet)
The blades are lined up.

Next, the operation of this embodiment will be described with reference to FIG. In FIG. 1, as described in the conventional example, the solid matter charged through the charging port 2 (see FIG. 2) naturally falls in the power mill. The solid matter is crushed by a plurality of crushing blades 6 arranged on the rotary blade 1 during the fall. Since the blade direction of the crushing blade 6 is formed parallel to the falling direction of the solid matter, even if the falling speed of the solid matter is increased, there is a chance of being sufficiently crushed below the crushing blade 6, and the crushing of the power mill Y is performed. The efficiency can be improved.

[0014]

As described above, according to the present invention, since the crushing blades of the rotary blades of the power mill are of a rigid type, the crushing efficiency can be improved, and the falling speed of solid matter is less likely to affect the crushing efficiency. There is also the effect.
