TECHNICAL FIELD The present invention relates to a crushing device for crushing an old glass bottle into fine pieces.

[0002]

2. Description of the Related Art An old glass bottle that cannot be used can be melted and recycled as a new glass product. However, the glass bottles collected for regeneration are bulky due to the large hollow sections, and thus require a large collection area. In particular, such a glass bottle for recycling needs a larger space because it needs to be sorted by color. In addition, since the glass bottle is bulky, it is difficult to handle such as transportation.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a glass bottle crushing apparatus according to the present invention is shown in FIGS. 1 to 3. This apparatus includes a crushing cylinder 1, a rotary crushing body 9 and a hopper body 13.

In the crushing cylinder 1, the upper and lower end openings of the cylinder 2 fixed to the support base 26 in an inclined position are closed by the end plates 3 and 3, and the hopper body lower fitting port 4 is formed at the upper end and A discharge port 5 for discharging the crushed glass pieces P is formed in the lower part of the side, and a fixing plate 6 whose lower end reaches the discharge port 5 is provided along the generatrix direction on the lower side of the inner surface, and a crushing gap 7 is formed. The fixing member 8 that is continuous with the fixing plate 6 is provided therebetween.

Both ends of the rotary crushing body 9 are the end plates 3 and 3.
Blades 11 are provided equiangularly and radially along the axial direction on a shaft body 10a, which is a portion of the rotating shaft 10 supported by the shaft body 10a located inside the crushing cylinder 1, and a blade plate at the lower end of the shaft body 10a. A crushing plate 12 that passes through the crushing gap 7 and crushes the glass bottle B at that time is provided between 11 and 11 radially. The rotating shaft 10 is rotatable by inserting both ends thereof into bearings 25 fixed to the end plate 3.

The lower portion of the hopper body 13 is a crushing cylinder body 1.
Has a charging port 14 through which the glass bottle B is charged, and glass fragments are scattered to the charging port 14 at a portion facing the fitting port 4 of the crushing cylinder 1. The return wall 15 for preventing the above is formed.

In this embodiment, the rotary crushing body 9 is rotated by the impact wrench 22. As a result, a shocking torque can be continuously applied to the rotary crushing body 9, so that the glass bottle B can be effectively crushed.

The glass bottle B dropped from the charging port 14 into the hopper body 13 has a space 13 between the lower edges of the hopper body 13 in the generatrix direction.
Adjacent vanes 1 centered on the shaft body 12a from between a and 13a
It falls between 1 and 11. The large bottle is pushed by the trailing blade 11 and collides with the lower edge 13b of the hopper plate, and is pressed and destroyed by the succeeding blade 11 until it reaches a size that can pass through the lower edge 13b of the hopper body. .

The glass piece P that has passed through the lower edge 13b of the hopper body moves along the fixed plate 6 in the cylinder 2 in the generatrix direction, and is sandwiched between the fixed plate upper corner 6a and the blade tip 11a to be further subdivided. It

The glass piece P sliding down in the cylinder 2 and reaching the crushing plate 12 enters the crushing gap 7 between the fixed plate 6 and the fixing member 8 and is crushed by the crushing plate tip 12a.

The finely crushed glass pieces P are discharged from the discharge port 5. In the present embodiment,
A drawer container 24 for taking out the discharged glass pieces P is provided. In addition, a dust collector 23 is provided to treat dust generated during crushing.

The glass bottle B crushed in this way becomes a fine glass piece P. Therefore, a large amount of glass pieces P can be loaded in a narrow place without being bulky. Also, handling such as transportation becomes easy.

Further, in this embodiment, the end members 9a which are both ends of the rotary crushing body 9 are separated from the central member 9b which is the central portion, and the bolt holes 17a,
17b and flanges 16a, 1 having pin holes 18 formed therein
6b is attached. And the flanges 16a, 16b
The spigots 17c are fitted together, the knock pin 21 is inserted into the pin hole 18 for positioning, the bolt 19 is inserted into the bolt hole 17, and the nut 20 is tightened to assemble the end member 9a and the central member 9b. ing.

Since the rotary crushing body 9 receives a large impact when crushing the glass bottle B, it is easily damaged in a relatively short period of time.
It costs money to replace the whole damaged rotary crushed body 9 with a new one, but in the present embodiment, the end member 9a is used as it is, and only the central portion, which is the severely damaged portion, needs to be replaced, which is economical. Excellent in.

[0019]

EFFECTS OF THE INVENTION According to the glass bottle crushing apparatus of the present invention, old glass bottles B collected for recycling can be easily crushed into fine pieces, and can be efficiently loaded in a narrow place.

Further, by making the end member 9a of the rotary crushing body 9 contactable and separable from the central member 9b, only the central portion which is easily damaged can be exchanged, which is excellent in economic efficiency.
