Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is used in the field of crushing glass tubes for fluorescent lamps and the like discarded from households.

(b) Prior Art Generally, glass tubes such as fluorescent lamps discharged from households are crushed and used for reuse or landfill.

However, when crushing glass tubes, there is a risk of the glass tube fragments flying around and injuring workers, and if the glass tubes are not crushed enough,
There is a problem in that efficiency decreases when transporting to factories or landfill sites for reuse.

(c) Problems to be Solved by the Invention The present invention solves the above-mentioned problems by providing a first crusher for coarse crushing and a second crusher for finely crushing the glass in the upper and lower parts of the casing. This allows the pipe to be shredded into small pieces without scattering the pieces.

(d) Means for solving the problem The present invention has a cylindrical elongated chute that is inclined forward and downward facing the upper part of the casing, and a rough elongated chute that faces the elongated chute at the upper part of the inside of the casing. A first crusher for crushing is provided, a second crusher for fine crushing is provided below the first crusher, a discharge port is provided in the lower part of the casing, and the first crusher has a long tip. The second crusher has a crushing blade swingably provided so as to come into contact with a cradle provided on an extension of the shaku chute, and the second crusher has a pair of rollers facing each other and rotating in opposite directions. The present invention relates to crushing equipment such as the following.

(e) Example The following example will be explained using drawings. 1 is a trolley 2
A casing provided above. A cylindrical elongated chute 3 inclined forward downward is provided at the upper part of the casing 1, and the elongated chute 3 guides a fluorescent lamp 4 to be crushed into the casing 1.

A discharge port 5 is formed in the lower part of the casing 1,
The crushed glass pieces are transferred from the discharge port 5 to a drum can 6, which will be described later.

Inside the casing 1, a first crusher 7 for coarse crushing is provided in the upper part, and a second crusher 8 for finely crushing is provided in the lower part.

The first crusher 7 includes a motor 1 that pivotally supports a crushing blade 9 in a swingable manner at a position facing the extension chute 3, and a portion of the crushing blade 9 is provided outside the casing 1.
0 is connected by an arm 13 and a link 12 that passes through a slit 11 in the casing 1, and as the arm 13 rotates, the crushing blade 9 swings, and the tip of the crushing blade 9 is provided on an extension of the elongated chute 3. It is adapted to come into contact with the pedestal 14 that is placed.

The second crusher 8 includes a pair of rollers 15 and 16.
are provided in parallel, and a plurality of protrusions 17 are provided on the surfaces of both rollers 15 and 16 to improve the biting of glass pieces.
... is provided, and this protrusion 17 ... faces the roller 1
5 and 16.

Further, one roller 15 is rotated by a motor 18 outside the casing 1 to the opposite roller 16 side,
The other roller 16 is rotated toward the opposing roller 15 due to the frictional force with the one roller 15 . The other roller 16 is supported by a long hole 19, and is normally pressed against the one roller 15 side by a spring 20. If a hard object such as metal is inserted between the pair of rollers 15 and 16, the other roller 16 is supported by a long hole 19. The roller 16 slides on the elongated hole 19 to widen the gap between the rollers 15 and 16 so that the rollers 15 and 16 are not damaged.

Reference numeral 21 denotes an opening/closing device provided on the elongated chute 3, in which a front cover 22 and a rear cover 23 are swingably provided at the front and rear of the elongated chute 3 with a distance longer than the fluorescent lamp 4, and both the lids 22, Each arm 24, 25 attached to 23
are connected by a rod 26 so that when one is opened, the other is always closed, and the arms 2
5 is provided with a spring 27 so as to always bias the rear lid 23 in the closing direction.

A transfer pipe 28 is connected to the discharge port 5, and the end of the transfer pipe 28 is connected to a cover 29, which is provided above the drum 6 placed on a handcart 30.

A blower 31 is attached to the cover 29, and this blower 31 sucks the air in the drum 6 and supplies this air through an air pipe 32 to a location opposite to the outlet 5 of the casing 1.
This air is used to forcefully feed the glass pieces.

33 is a guide for guiding the glass pieces crushed by the first crusher 7 to the second crusher 8. 34 is a vibrator provided on the long chute 3.

35 is a filter provided in the blower 31.

The present invention has the above-mentioned structure, and the operation thereof will be explained next. First, the motors 10 and 18 are started to swing and rotate the crushing blade 9 and the rollers 15 and 16 in the direction of the arrow.

When the fluorescent lamp 4 is inserted into the long chute 3 in this state, the rear cover 23 is pushed open and the fluorescent lamp 4 is inserted.

When the fluorescent lamp 4 enters the front of the rear lid 23 as shown in the figure, the rear lid 23 is closed by the spring 27, and the front lid 22, which had been closed until then, is opened, and the fluorescent lamp 4 is inserted into the base of the crushing blade 9. It slides due to its own weight and the vibration of the vibrator 34 until it hits the .

The fluorescent lamp 4 that has entered the casing 1 is successively crushed by being sandwiched between the crushing blade 9 and the pedestal 14 by the swinging of the crushing blade 9.

The coarsely crushed glass pieces are guided between a pair of rollers 15 and 16 by a guide 33, and are guided between a pair of rollers 1
It is finely crushed by the protrusions 17 of 5, 16.

At that time, there is metal at both ends of the fluorescent lamp 4, and when the metal comes between the pair of rollers 15 and 16, the other roller 16 slides and the metal is moved between the rollers 15 and 16.
5 and 16 can be passed through without stopping or damaging them. The finely crushed glass pieces are transported from the discharge port 5 through the transfer pipe 28 to the drum can 6 using air supplied by the blower 31.
will be transferred to.

The air is further sucked in by a blower 31 and recycled.

When the drum 6 is full, the cover 29 is removed, the cover 29 is attached to the empty drum 6, and the crushing process is restarted.

(f) Effects of the invention As described above, in the present invention, the crusher is housed in the casing, so there is no fear of glass fragments scattering and injuring workers.
After the crusher coarsely crushes the glass, the second crusher finely crushes it, so even if the diameter of the pair of rollers in the second crusher is made smaller, the glass pieces are still able to penetrate into the glass pieces, making the entire device more compact. It can be done.
