BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating carbon in a dry cleaning machine.

[0002]

2. Description of the Related Art In a dry cleaning machine in which a solvent is supplied into a basket for accommodating an object to be cleaned and the solvent is contaminated with impurities such as dirt and dust, the cleaning ability is reduced. It is necessary to remove them constantly to purify the solvent. At the time of the purification, the solvent is inserted through a cartridge filter provided in a solvent circulation path to remove impurities such as dust, the solvent is supplied into a carbon tank, and carbon (activated carbon) provided in the tank is supplied. Thus, impurities such as fatty acids, dyes or moisture in clothes dissolved in the solvent are removed.

[0003] By the way, the above-mentioned carbon, when used for a long time, causes impurities to adhere to the carbon surface and deteriorates the purifying action. Therefore, it is necessary to periodically replace the carbon. Conventionally, at the time of replacement, the solvent in the carbon tank is removed by its own weight to the distiller, and then the carbon is taken out from the inspection port provided in the tank and processed.

[0004]

[Problems to be Solved by the Invention] However, the carbon taken out of the tank has a problem that the working environment is deteriorated because the solvent is volatilized because the solvent remains attached, and the solvent is volatilized. There is also a problem that the loss of the solvent is large.

Therefore, an object of the present invention is to provide a carbon treatment apparatus capable of treating carbon without deteriorating the working environment and losing the solvent.

[0006]

To solve the above problems BRIEF SUMMARY OF THE INVENTION This invention is in the circulation path of solvent for connecting the basket and the solvent tank, the solvent in the solvent tank to the basket
Pump to discharge and solvent on the discharge side of the pump
Cartridge filter to remove dust inside
Fat contained in the solvent filtered by the cartridge filter
Set up a carbon tank to remove acids, dyes, etc.
An on-off valve in the passage that leads the solvent in the carbon tank to the still
Provided, the solvent was distilled above distiller, the dry cleaning machine was returned to the solvent tank, the port
Between the pump discharge side and the carbon tank outlet side.
And connect the above carbon tank and the distiller
The passage has a size that allows carbon to flow therethrough .

[0007]

In the above construction, the opening / closing valve of the passage is opened and the solvent tank is opened .
When the solvent in the tank is supplied into the carbon tank through the solvent supply passage, the carbon in the tank is discharged into the distiller through the passage together with the solvent. After the discharge is completed, the on-off valve is closed and distillation is performed to remove the solvent from the carbon, and the remaining carbon is removed from the still. Thereby, carbon can be treated without deteriorating the working environment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a solvent tank, 2 is a basket, 3 is a pump, 4 is a cartridge filter, 5 is a carbon tank, 6 is a button trap, and the solvent pumped from the solvent tank 1 by the pump 3 is: It is supplied into the basket 2 through the solvent supply passage 7. The supplied solvent is circulated through a circulation path 8 that connects the basket 2 → the button trap 6 → the pump 3 → the cartridge filter 4 → the carbon tank 5 → the basket 2; dust passing through the cartridge filter 4 is removed; When passing through the inside, impurities such as fatty acids and dyes are removed.

In the circulation path 8, the discharge side of the pump 3 and the outlet side of the carbon tank 5 communicate with each other through a solvent supply passage 7, and a passage 10 connecting the supply passage 7 and the still 9 is connected in the middle of the passage. An on-off valve 11 is provided in the passage 10.

The still 9 has a steam supply nozzle 12a for direct heating inside, and a heating device 12b at the bottom to heat and distill the supplied solvent. A solvent vapor passage 13 for communicating the still 9 with the solvent tank 1
Is connected to a condenser 14 and a water separator 15.

The still 9 and the carbon tank 5 are connected by a carbon discharge passage 16. Passage 16
Has a size that allows carbon (activated carbon) filled in the carbon tank 5 to flow therethrough, and is opened and closed by an on-off valve 17.

This embodiment is configured as described above.
The solvent used for washing in the basket 2 is sent to the cartridge filter 4 and the carbon tank 5 by the pump 3 for purification, and the purified solvent is sent to the basket 2.

When the above-mentioned purifying operation is repeated and the purifying action of the carbon in the carbon tank 5 is reduced, it is necessary to replace the carbon. At the time of replacement, the carbon discharge passage 16 connecting the carbon tank 5 and the distiller 9 is used.
After the on-off valve 17 provided in the tank is opened, the solvent in the solvent tank 1 is supplied from the solvent supply passage 7 into the carbon tank 5 by operating the pump 3. The supplied solvent passes through the carbon discharge passage 16 together with the carbon in the tank 5 and passes through the still 9
Is discharged into

After the discharge is completed, the on-off valve 17 is closed and the still 9
The carbon and the solvent are heated by the steam supply nozzle 12a and the heating device 12b provided in the above, and the solvent is vaporized. As a result, the solvent is removed from the carbon, and the vaporized solvent enters the condenser 14 via the solvent vapor passage 13 and is liquefied therein. Thereafter, the specific gravity of the solvent and water is separated by the water separator 15, and the solvent is recovered in the solvent tank 1.

In this way, the solvent can be completely removed from the carbon, and after the distillation is completed, the dried carbon can be taken out from the still 9 and discarded.

[0017]

As described above, according to the present invention, the carbon tank and the distiller are connected by a passage through which the carbon can flow, and an opening / closing valve is provided in the passage. And can be distilled out. Therefore, the solvent can be completely removed from the carbon, and after the distillation is completed, the carbon can be taken out from the distiller and discarded, so that air pollution and deterioration of the working environment can be reduced.

Further, since the removed solvent is collected in the solvent tank, the carbon can be treated without losing the solvent. In addition, the solvent supplied into the carbon tank
Forcibly through the solvent supply passage.
And use the solvent to remove the carbon in the carbon tank
Flow smoothly into the wastewater
Rate up can be measured.
