Abstract

PROBLEM TO BE SOLVED: To provide a grinding method and a grinder rounding the corner parts of the ground cross section of glass ground pieces to produce glass ground pieces having the natural gloss and transparency of glass itself. SOLUTION: Glass is struck and crushed by impeller hammers 5 rotating at a high speed within a casing 3 and glass crushed pieces larger than the gaps between the impeller hammers 5 and a lower liner 20 are left in the lower liner part because the impeller hammers striking and crushing glass are inclined to escape and struck and crushed by the scceeding impeller hammers rotating at a speed and the glass crushed pieces scattered when struck and crushed are repelled and scattered by the impeller hammers rotating at a high speed to collide with the impeller hammers, upper and lower liners 15, 20 and side surface liners to be rounded by a V-shaped groove parts provided to the surfaces of the liners and repeated scattering impact action, and these glass crushed pieces become smaller than the gaps to fall from the material discharge port 12 of a lower casing 32 to be recovered in a discharge hopper 7.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a glass for disposal,
In particular, the present invention relates to a glass crushing method and a glass crusher for crushing a glass bottle such as a wine bottle.

[0002]

2. Description of the Related Art Since 2000, the Containers and Packaging Recycling Law has been enforced, and the collection and recycling of various containers has become mandatory. Among them, there are two types of glass bottles: a washing and reusing method as a return bottle, and a pulverizing and reusing method as a one-way bottle. Conventionally, in a sliding rotating device known as a method for reusing pulverized glass, the sharpness of the crushed glass piece (cullet) is excessively abraded due to the sharp corner, and the gloss of the surface of the crushed glass piece (cullet) and the inherent characteristics of glass are reduced. Certain transparency was impaired, and only the production of crushed glass pieces (cullet) of cloudy shades, such as frosted glass, was possible. In addition, when using crushed glass pieces (cullet) as a mixed mixture such as asphalt mixture, the fractured surface of the crushed glass pieces (cullet) has sharp corners. After completion, there are drawbacks such as scratching tires and the like and accelerating wear. For this reason, crushed glass pieces (cullets) have been used only for extremely limited applications.
By rounding (chamfering) the corners of the crushed cross section of the crushed glass piece (cullet), applications can be expanded.

[0003]

Therefore, it is possible to round (chamfer) the corners of the crushed cross section of the crushed glass piece (cullet), and at the same time, the glass has the natural gloss and transparency inherent to glass. An object of the present invention is to provide a glass pulverizing method and a glass pulverizer capable of producing pulverized pieces (cullet).

[0004]

On the other hand, the broken glass fragments that were scattered when hit and crushed
It is flipped off by the impeller hammer 5 that rotates at a high speed in sequence, and collides with the impeller hammer 5 or the upper liner 1
5. The glass crushed pieces are rounded by colliding with the lower liner 20 and the side liners 21 and 22 and repeating the scattering impact action with the V-shaped groove 18 on the surface of the liner, so that the glass finally becomes smaller than the gap. The crushed pieces fall from the material discharge port 12 of the lower casing 32 and are collected by the discharge hopper 7. Further, the glass crusher of the present invention includes a cylindrical casing 3 fixed on the gantry 1, a large number of impeller hammers 5 rotating via a rotary shaft 4 inside the casing 3, and a circular shape of the casing 3.

At the time of high speed rotation, as shown in FIG.

Next, when the glass bottle to be disposed of is put into the charging hopper 6, the glass bottle falls from the material inlet 11 of the upper casing 31 into the lower casing 32.
The glass bottle that has fallen is hit and crushed by the high-speed rotating impeller hammer 5 and scattered around, and the broken glass pieces larger than the gap between the impeller hammer 5 and the lower liner 20 are inclined by the hit and crushed impeller hammer 5. As a result, it is left in the lower liner 20 and then hit and crushed by the impeller hammer 5 rotating at a high speed.

In this manner, the glass bottle is crushed by the action of the impeller hammer 5 and the lower liner 20, and gradually becomes scattered and abraded by the impeller hammer 5 and the teeth 17 of the lower liner 20 to form a corner of the crushed glass piece. When the crushed glass pieces are finally rounded, and finally become crushed glass pieces, that is, crushed glass pieces (cullets), they fall from the material discharge port 12 of the lower casing 32 and are collected by the discharge hopper 7.

On the other hand, the crushed glass fragments scattered at the time of impact crushing are blown off by the impeller hammer 5 which rotates sequentially at a high speed, and collide with the impeller hammer 5 or the upper liner 15, the lower liner 20 and the lower liner 20. Side liner 2
The glass crushed pieces are rounded by colliding with the V-shaped grooves 16 on the liner surface by colliding with the crushed pieces 1, 22 or the like, so that the glass crushed pieces are finally rounded. When it becomes (cullet), it falls from the material discharge port 12 of the lower casing 32 and is collected by the discharge hopper 7. In addition, upper liner 1
5. Since the lower liner 20 is provided with the teeth 17 having the V-shaped grooves 16, there is a possibility that the crushed glass pieces (cullets) may be accumulated in the grooves 16 without being discharged, as shown in FIG. And a U-shaped groove 18 crossing the teeth 17 at an angle
The crushed glass pieces (cullet) can be discharged through the U-shaped groove 18 because they are provided in the shape.

[0021]

As described above, the glass crusher of the present invention strikes and crushes the glass bottle by the high-speed rotating impeller hammer and causes the glass bottle to scatter and collide, so that the corner of the crushed cross section of the glass crushed piece (cullet) is rounded.
