Description

  The present invention relates to a glass particle manufacturing apparatus that manufactures glass particles by crushing glass such as bottles that are no longer needed.

Glasses such as bottles, empty ampules and broken window glass that were no longer needed were not only bulky but also very difficult to process because they were dangerous to break.
Therefore, the present applicant firstly installed the blade mounting portion on the bottom of the container so as to be rotatable, and extended the blade radially from the blade mounting portion, and connected the blade mounting portion to the output shaft of the motor. A manufacturing apparatus was proposed (see Patent Document 1).
According to the glass grain manufacturing apparatus, by putting glass into a container and driving a motor, the glass can be crushed by rotating blades to automatically produce fine glass grains.

However, this glass manufacturing apparatus is designed to open the lid of the container and insert glass, pulverize it into glass particles, discharge from the container, and then add new glass. Therefore, when replacing the glass in the container, the apparatus must be stopped, and it has been difficult to quickly process a large amount of glass.
In addition, when glass is continuously fed into this glass grain production device and the produced glass grains are continuously discharged, only rotating radial blades are installed in the container. There is a risk that a large glass lump may be mixed into the glass particles.

  The problem to be solved by the present invention is to provide a glass grain production apparatus capable of producing high-quality glass grains continuously and efficiently.

The glass grain manufacturing apparatus of the present invention has a funnel which is provided with an inlet into which glass is continuously charged at the upper part of a bottomed cylindrical container, and is inclined so that the diameter becomes smaller toward the lower part near the lower part of the container. An inclined bottom is provided, and the inside of the container is partitioned into an upper crushing space and a lower crushing space by the inclined bottom, and a drop opening that communicates the upper crushing space and the lower crushing space is formed at the lower end of the inclined bottom And a rotating shaft is disposed along the central axis of the upper crushing space, a number of swiveling members are suspended at different positions of the rotating shaft, and the rotating blades are placed in the lower crushing space in the container. And a discharge path through which glass particles are continuously discharged from the lower crushing space to the outside of the container, and the rotating shaft and the rotating blades are driven by a motor.
The pivot member may be a chain.

According to the present invention, glass is continuously charged into the container from the inlet, and the produced glass particles are continuously discharged to the outside of the container while crushing the glass. Glass particles can be produced efficiently.
In addition, the glass is crushed by the swivel member while passing through the upper crushing space and becomes smaller. Then, when the glass reaches the lower crushing space from the drop port, it is finely crushed by the rotating blades. It is possible to obtain fine and high-quality glass particles even when the glass particles produced are continuously discharged while the produced glass particles are continuously discharged.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIG.1 and FIG.2, the glass grain manufacturing apparatus of this invention has the bottomed cylindrical container 1. As shown in FIG.
The upper end surface of the container 1 is closed with a lid 2, and a glass charging duct 4 is connected to a charging port 3 formed in the lid 2. Glasses such as an empty bottle, an empty ampule, and a broken glass plate are continuously fed into the container 1 through the glass charging duct 4 and the charging port 3.

Near the lower part of the container 1, a funnel-shaped inclined bottom 5 is provided so as to be smaller in diameter toward the lower side. The
In addition, a drop port 8 that communicates the upper crushing space 6 and the lower crushing space 7 is formed at the lower end of the inclined bottom 5 so as to be positioned on the central axis of the container 1.
Further, a discharge path 9 whose tip side is inclined downward extends from the side surface of the lower breaking space 7 toward the outside of the container 1. The lower part of the inner peripheral surface of the lower crushing space 7 is a curved surface that gradually decreases in diameter toward the lower side.

In the center of the bottom of the lower breaking space 6, a blade mounting portion 10 is rotatably installed immediately below the drop opening 8, and a plurality of rotating blades 11 project radially from the blade mounting portion 10. The rotating blade 11 is made of a metal having high wear resistance, and the outer end of the rotating blade 11 has a curved shape in which a vertical cross-sectional shape is curved outward and downward. It matches with the curved surface formed in the lower surface.
Further, an output shaft 12 of a motor (not shown) installed below the container 1 is connected to the blade mounting portion 10.
Furthermore, the lower end of the rotating shaft 13 is fixed to the blade mounting portion 10.

The rotation shaft 13 extends along the central axis of the upper crushing space 7 through the drop port 8, and the upper end portion thereof penetrates the lid 2 of the container 1.
A large number of U-shaped locking metal fittings 14 are mounted around the rotation shaft 13 at different heights, and the turning members made of chains 15 are suspended from the locking metal fittings 14 respectively.
The chain 15 has such a length that the tip thereof is slightly separated from the peripheral surface of the upper crushing space 6 when turning. That is, the chain 15 arranged inside the inclined bottom 5 is shorter as it is lower.
When the motor is driven, the blade mounting portion 10 connected to the output shaft 12 rotates, the rotating blade 11 rotates in the lower crushing space 7, and the rotating shaft 13 fixed to the blade mounting portion 10 rotates. Move.
As a result, a large number of chains 15 suspended from the rotating shaft 13 are swung at different positions in the upper crushing space 6 while projecting from the rotating shaft 13 by centrifugal force.

This glass grain manufacturing apparatus is used as follows.
The motor is driven to rotate the rotating shaft 13 and the rotating blade 11, and the glass is introduced into the upper crushing space 6 of the container 1 through the glass introduction duct 4 and the introduction port 3.
While dropping into the upper crushing space 6, the introduced glass is smashed by a large number of swirling chains 15, blown off by the chains 15, collides with the side wall of the container 1, and is crushed into small pieces.
Glasses are gradually crushed while repeatedly colliding with the chain 15 and the side wall of the container 1, guided to the inclined bottom 5, and gathered at the central outlet 8.

The small crushed glass falls through the dropping port 8 to the vicinity of the center of the lower crushing space 7, and further collides with the rotating blade 11 and is crushed.
The crushed glass particles are pushed by the rotating blades 11 and moved in the circumferential direction, and rubbed to take a sharp corner.
The sufficiently fine glass particles are pushed upward along the curved surface formed on the inner periphery of the lower crushing space 7 by centrifugal force, and the discharge path 9 provided on the side surface of the lower crushing space 7. It is continuously discharged to the outside of the container 1 through.
Note that one end of the striking rod may be hung on the rotating shaft 13 as the turning member.
