Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple crusher for crushing unnecessary linear fluorescent lamps in buildings such as ordinary homes, offices, and buildings.

[0002]

2. Description of the Related Art Generally, when discarding fluorescent lamps that are no longer needed in a home or a business, at present, they are discarded as they are as garbage. However, since many parts of the fluorescent lamp are made of glass, there is a danger that the bag is broken in a garbage bag, the bag is broken, and there is a risk that the fragments are damaged, and the whole is bulky and cannot be compactly packed. In addition, the mercury gas filled in the fluorescent lamp is harmful because it diffuses into the air when the fluorescent lamp is cracked, causing problems such as environmental pollution.

[0003]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a linear fluorescent lamp which is no longer required in a home or office can be easily crushed into small dusts and discarded as non-burnable refuse in a compact manner. It is another object of the present invention to provide a compact fluorescent lamp crusher capable of effectively absorbing mercury gas generated during crushing and preventing pollution to the atmosphere.

[0004]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the fluorescent lamp crusher according to the present invention, a substantially linear duct 4 having an input port 2 at an upper end and a lower end communicating with the crushing chamber 3 of the crusher main body 1 is attached to an intermediate portion of the duct 4. A mercury gas inhaler 5, a motor 7 for driving a crushing blade 6 disposed in the crushing chamber 3, an outlet 8 opened at a lower end of the crushing chamber 3, And a stay 9 for freely changing the vertical position of the
A sealable opening / closing lid 10 is provided at the charging port 2 of the first embodiment.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In practicing the present invention, the above-mentioned inlet 2 has a linear shape of 20 watts and 40 watts.
It is formed with a size such as 60 or 100 watts that can pass through a fluorescent lamp. The length of the duct 4 is preferably set to a dimension such that the fluorescent lamp can be completely accommodated in the duct when the duct 4 itself has a double tube structure that can be extended and contracted and is extended to the maximum.

Further, it is preferable that the opening / closing lid 10 is opened by the pressing force when the fluorescent lamp is turned on, and is automatically returned to the closed position when the fluorescent lamp is turned on and the pressing force disappears.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show an embodiment of a fluorescent lamp pulverizer according to the present invention, in which a lower end of a vertical duct 4 having an input port 2 at an upper end is used to pulverize the pulverizer main body 1. It is attached to the crusher main body 1 so as to communicate with the chamber 3. This duct 4 is, as shown in FIGS.
a and the outer tube 4b so as to be extendable and contractible.
Can be fixed by the tightening ring 11 in a state where is extended upward. The inner diameters of the above-mentioned inlet 2 and duct 4 are formed so as to allow the passage of linear 20 W and 40 W fluorescent lamps A. The length of the duct 4 is set to such a size that the fluorescent lamp A can be completely accommodated in the duct when the duct 4 is extended to the maximum.

An opening / closing lid 10 that can be sealed is provided at the inlet 2 of the duct 4. In this embodiment, the opening / closing lid 1 is used.
As shown in FIG. 4, 0 is always held in the closed position by the spring 12, and when the fluorescent lamp A is pushed in from above the lid, it is opened by this pressing force. It is configured to return to.

A mercury gas inhaler 5 is provided at an intermediate portion of the duct 4. Although not shown, the mercury inhaler 5 has a built-in suction blower and an exchangeable filter for absorbing mercury gas, and sucks mercury gas generated when the fluorescent lamp is crushed in the crushing chamber 3 by the suction blower. And remove it with a filter.

Further, as shown in detail in FIGS. 2 and 3, a crushing blade 6 is disposed in the crushing chamber 3, and a motor 7 for driving the crushing blade 6 is attached to the crusher main body 1. I have. Further, a discharge port 8 for discharging the crushed dust is provided at a lower end of the crushing chamber 3. Further, the crusher main body 1 is held by a stay 9 so as to be vertically movable, and is formed so that the crusher main body 1 can be moved up and down by loosening a knob 13. Reference numeral 7a denotes a drive shaft directly connected to the motor 7.

In the fluorescent lamp crusher constructed as described above, the duct 4 is extended as shown in FIG. 5 at the time of use, and then the crusher body 1 is moved to a position above the stay 9 to be fixed, and the discharge port 8 is used. A dust storage bag 14 is attached to the lower part of the case. The linear fluorescent lamp A input from the input port 2 is crushed into small pieces by the crushing blades 6 of the crushing chamber 3 sequentially from the lower end portion, and is discharged from the discharge port 8 to the dust storage bag 14.
The mercury gas generated during the crushing of the fluorescent lamp is absorbed by the mercury inhaler 5 and is not released to the atmosphere. Further, the mercury gas is not released from the inlet 2 because the inlet 2 is naturally closed after the fluorescent lamp is put into the duct 4. The motor for driving the crushing blade 6 and the mercury inhaler 5 is manually turned on. Although an OFF operation may be performed, if a fluorescent lamp is input from the input port 2, this may be automatically detected and each motor may be driven.

Although the representative embodiment of the present invention has been described above, the present invention is not necessarily limited to the above-described embodiment structure, but may be provided within the scope of providing the constituent features of the present invention and having the effect. Needless to say, the present invention can be implemented with appropriate changes.

[0013]

As described above, the present invention is constructed as described above, so that unnecessary linear fluorescent lamps can be easily crushed into small dusts and discarded compactly as non-burnable dust. Mercury gas generated during pulverization can be effectively absorbed to prevent pollution to the atmosphere, and the equipment is simple and compact, so it can be easily used anywhere and can be provided at a low price. is there.
