Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing apparatus for separating and recovering a complex consisting of a solid material such as a simple body warmer or confectionery and a packaging bag for each material.

In recent years, the recycling of resources has been promoted from the viewpoint of environmental protection, and there is a demand for the reuse of waste materials even in disposable simple warmers. However, the simple body warmer is a composite body composed of a solid containing metal powder such as iron powder as a main component and a packaging bag such as a plastic bag for packaging the solid. Therefore, in order to reuse each material of the simple body warmer, it is necessary to separate the solid matter from the packaging bag and to crush the solid bag into a shape and size that can be easily collected.

[0003]

However, there is no existing device capable of crushing and separating the solid matter and the packaging bag constituting the simple warmer. For example, a gypsum board crusher can crush and separate gypsum and paper by shearing, but cannot crush a simple body warmer and separate it into solids and packaging bags. Even if crushing is attempted, a package such as a plastic bag cannot be crushed by shearing.

[0004] It is also desired in other industrial fields such as the confectionery industry to efficiently separate and collect solids and packaging bags. For example, solids such as oysters are wrapped in packaging bags. It is extremely convenient if there is a device capable of separating and recovering the solid matter and the packaging bag simply by supplying as is.

[0005] The present invention provides a composite comprising a solid and a packaging bag, which can separate and collect the solid and the packaging bag simply by supplying the solid and the packaging bag in a packaged state. It is an object of the present invention to provide a crushing device.

The material, diameter, and thickness of the high-speed crushing blade 8 are configured in the same manner as the low-speed crushing blade 4.

It is preferable that the high-speed rotating shaft 7 and the low-speed rotating shaft 3 are made of the same material and have the same diameter, since it is easy to manufacture the crushing apparatus 1, but in the present invention, different materials may be used. Different diameters are possible.

It is preferable that the high-speed crushing blade 8 and the low-speed crushing blade 4 are made of the same material and have the same diameter and thickness, because the crushing apparatus 1 can be easily manufactured. However, different materials and different diameters and thicknesses can be used in the present invention.

The shape and dimensions of the projection 9 are the same as those of the projection 5. It is preferable that the shape and the size of the convex portion 9 are the same as those of the convex portion 5 because the manufacture of the crushing device 1 is easy.

The difference between the angle α and the angle β is 0.1 to 30 degrees. When the angle α and the angle β are set in this way,
The composite can be crushed more uniformly, and in particular, the packaging bag can be finely shredded.

The provision of the crushed piece removing recess 10 within this range can prevent the crushed powder and crushed pieces of the composite from being caught between the low-speed crushing blade 4 and the high-speed crushing blade 8, so that the low-speed rotation can be prevented. The section 2 and the high-speed rotating section 9 can be smoothly rotated.

In the present invention, the gap G1 between the peripheral surface of the low-speed rotating shaft 3 and the upper end surface of the convex portion 5 of the high-speed crushing blade 8 and the gap G1 between the peripheral surface of the high-speed rotating shaft 7 and the convex portion 9 of the low-speed crushing blade 4 are formed.

May not rotate smoothly. On the other hand, the gap G1,
When G2 and G3 exceed 10 mm, the crushed powder and crushed pieces become too large, and there is a possibility that the collection process in the subsequent step cannot be performed efficiently.

In the present invention, the convex portion 9 of the high-speed crushing blade 8 is used.

When the peripheral speed of rotation at the upper end surface of the convex portion 9 of the high-speed crushing blade 8 is less than 1.3 times the peripheral speed of rotation at the upper end surface of the convex portion 5 of the low-speed crushing blade 4, efficient crushing can be achieved. It may not be possible. On the other hand, when the peripheral speed of rotation at the upper end surface of the convex portion 9 of the high-speed crushing blade 8 exceeds 10 times the peripheral speed of rotation at the upper end surface of the convex portion 5 of the low-speed crushing blade 4, the peripheral speed of rotation is high. Too much, and there is a possibility that the solid matter and especially the packaging bag may pass through without being sheared. In addition, the peripheral speed of rotation at the upper end surface of the convex portion in this specification refers to the speed at which the upper end surface of the convex portion of the crushing blade rotates.

With this configuration, the composite can be efficiently crushed by dropping the composite from above, so that the device has excellent workability.

In the present invention, as shown in FIG. 5, it is preferable that a sieve separating portion 22 for separating the crushed powder of the solid matter and the crushed pieces of the packaging bag be provided in the casing. When the sieving part 22 is provided, the crushed powder of the solid material and the crushed pieces of the packaging bag can be easily separated and collected.

The sieving part 22 is preferably of a type that vibrates the sieve up, down, left and right. Said sieve comprises a mesh,
A mesh having a mesh size of 5 to 50 mm is preferable for sieving crushed powder obtained by crushing a simple warmer and crushed pieces. However, the mesh in the present invention is not limited to the above dimensions, but is appropriately determined by the size of the crushed powder of the solid material and the size of the crushed pieces of the packaging bag.

The crushing apparatus of the present invention is particularly effective for crushing, separating and collecting a simple warmer comprising a solid material mainly composed of iron powder and a plastic film mainly composed of a plastic film.
