Description

DETAILED DESCRIPTION OF THE INVENTION The present invention-1 relates to a rotary glass crusher with an eccentric circular rotor in a conical hopper.

Traditionally, empty bottles and other glass products were cleaned, melted, and remolded to reuse them. In this process, these glass containers are crushed and washed with water in order to remove impurities from the metal caps of bottles, paper labels, etc., and to separate and remove any adhering dirt, sand, or residual liquid. There is. The crusher conventionally used in the process of crushing glass products uses a device that rotates a hammer-shaped object at high speed inside a strong container to shatter the glass products that are thrown into it. In the case of this type of device, the impact of the hammer often caused the glass products to shatter into pieces. However, as mentioned above, in the next cleaning step, impurities are removed from the glass fragments by washing with water, but if the glass fragments are too small, they will be washed away along with the sludge-like impurities and will not be reused. On the other hand, in order to prevent it from becoming too detailed, if the rotational speed of the hammer is increased to
There are drawbacks such as insufficient force resulting in failure to crush.

There is also a crusher that uses several gear-shaped rotors or cams facing each other at a certain distance, and crushes the glass products by biting them between the rotors or cams. Although it is possible to select the size of the pieces by adjusting the size of the pieces, the disadvantage is that when the glassware is being caught between the rotors, it can slip and escape, making it difficult to be caught properly.

Press-type compression crushers are also known, but t1! −
Input process of glass products, which are shredded products, crushing process, and discharge of fragments after crushing.2 [The process is an intermittent process, resulting in poor efficiency.]
Secondly, it is difficult to select the appropriate size of the pieces.

1iL, the purpose of the present invention is to maintain the size of the broken glass fragments at a reasonable size and at the same time do not leave them fragmented (4+

4] A. To serve.

The eccentric cylindrical rotary rotary glass crusher in a conical hopper according to the present invention has a vertical conical hopper with a narrow lower part, and a rotating machine that rotates with the conical center #jl of this hopper as the center line of rotation. M, is provided in the hopper, and is composed of an eccentric cylinder integral with the central rotating shaft 111. The center of the circular lower surface of the rotor is on the center line of the hopper, and there is a gap between it and the inner wall of the hopper in the circumferential direction, and the center of the circular upper surface of the rotor is located off the center line of the hopper. It is configured. With this configuration, the material to be crushed is bitten between the hopper and the eccentric rotor by its own heavy tail, and is compressed and crushed between the hopper and the rotor due to the center motion of the rotor, and continuously rotates downward from the top of the hopper. It is crushed while moving in a spiral trajectory. Finally, it is crushed to a size that can pass through the minimum gap between the hopper and the rotor, passes through this minimum gap, and is discharged below the hopper.

In addition, the minimum gap between the rotor and hopper mentioned above can be adjusted as desired.
1j made it possible to arbitrarily select the size of the fragments after crushing. The above objectives of the invention have been fully achieved.

The present invention will be explained in more detail below using the drawings.

FIG. 1 is a side view showing an actual example of a glass crusher according to the present invention. In the figure, 1 is a conical hopper that receives objects to be crushed. For ease of understanding, only one position in the vertical plane containing the hopper centerline A-A is shown.

The popper 1 is fixed to a frame 4 together with a hopper upper plate 2 and a hopper lower plate 3 via brackets 3ai. Inside the hopper 1, there is an eccentric cylindrical rotor 5, and the center point Q of the lower surface of the rotor 5 is pivotally supported by a rotor center 6 via the hopper lower plate 3 on the hopper center line A-A.

The center point P of one plane of the eccentric cylindrical rotor 5 is the hopper center line A

9 I'm upset.

The material to be crushed that is introduced from the upper part of the hopper 1 is rotated on the A-A axis of the eccentric rotor 5, that is, the radius of the inner surface of the hopper 1 and the outer surface of the rotor 5 is caused by the eccentric rotation movement of the rotor 5 in the hopper 1. The gap in this direction continuously repeats contraction and expansion at all points within the same horizontal plane of the hopper, and the object to be crushed caught during this time is bitten and compressed and crushed. As the fragments become finer, they descend in the hopper 1 in a four-turn motion, rotating and descending.

The lower part of hopper 1 and rotor 5? The fragments crushed to a size smaller than the gap f in the dropping part pass through the gap f'z and fall downward.

Although not shown, a blowing rifling projection is provided on the outer periphery of the eccentric rotor 5, and functions as a screw that forcibly sends out the material to be crushed downward through a rotating motion. This screw effect prevents debris larger than the gap f in item 11 from clogging the gap 1fAt and blocking this gap.

The vertical position of the rotor 5 with respect to the hopper 1 can be arbitrarily changed by adjusting the adjustment screw portion 6a of the rotor center 6. By this operation, the size of the fragments of the object to be crushed can be selected by arbitrarily changing the size of the minimum empty Wf of the rotor 5 and hopper 1.

Book 1/i: In the experiments conducted by the inventor, the most effective rotation speed of the eccentric rotor 5 is 17 to 30 times per minute.
If the speed was slower than this, the efficiency would be poor, and if it was too fast, collisions between the objects to be crushed or between the rotor 5 and the hopper 1 would result in too many cracks. The above-mentioned good-+L.

In order to obtain a high speed and at the same time sufficient crushing compression force, the glass crusher according to the present invention has a speed ratio of 15T.
/20T bevel gearbox 9 and stepless variable converter 12
(S type reduction rock) is used as the power source for the rotor.
W, the rotation speed of the VT motor 10 of AC 200V is increased to 1. In addition, FIG. 2 shows the hopper ff1sj two-sided 1si1 of the glass crusher shown in FIG. 1, and FIG. 3 is a bottom view of a part of the hopper.

The above-mentioned L-rifled screw provided on the rotor 5 may be wound on the inner surface of the hopper 1, or may be wound on both the outer circumference of the rotor and the inner surface of the hopper.

The bevel gearbox 9 and the S-type reducer 2 may be a chain reducer, a worm or other gear reducer, a V-belt and pulley reducer, or other reducer device Pf. It is also possible to replace the electric motor 10jd with a drive device such as a hydraulic motor.

As mentioned above, the present invention will be explained with reference to an actual example.
The scope of the present invention is not limited thereto, but extends to the entire scope of the claims, including various modifications.
