Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for cleaning (dry cleaning) clothes for business use, which includes a solvent,
This low liquid level (designated liquid level) is obtained by showering a combination of a detergent with a low affinity with a processing agent with a strong affinity into the processing tank at the same time for each washing and minimum amount required for processing. )
At the first step, both agents in the treatment tank are circulated and sent only to the first filter to remove only insoluble dirt, and the second step is circulated and sent to both the first and second filters. It is characterized by gradually removing the insoluble, water-soluble and oil-soluble stains to enhance the rinsing effect, and removing all the stains at the end of cleaning and processing and returning it to the base tank as a clean solvent only. The present invention relates to a one-bath two-stage cleaning method and apparatus.

[0002]

2. Description of the Related Art A conventional cleaning apparatus for dry cleaning for business use is generally as shown in FIG. 2, and includes a processing tank 1 (having a processing drum), a base tank 2 and a processing unit. Agent tank 3, rinse tank 4, pump 5, adsorption filter 6, distiller 7, condenser 8,
It consists of a water separator 9, etc.,

To explain the cleaning operation, the amount of solvent is usually about 200 liters in the base tank 2, about 100 liters in the treatment tank 1, and about 100 liters in the adsorption filter 6 (mainly filled with activated carbon and a deoxidizing agent). The total is about 400 liters. First, about 4 as the initial charge.
About 1.2 liters of detergent to 00 liters (ratio of about 0.1
3%) in a circulating manner.

Approximately 20K of clothes per treatment tank 1
g, and while rotating the processing drum, about 8 liters of detergent (about 4% of about 200 liters of treatment tank) is injected, and set time (time varies depending on solvent, type of detergent, properties). Water is circulated and sent to the adsorption filter 6,
Cleaning is performed while adsorbing and removing oil-soluble dirt.

After cleaning for a set time, both agents in the processing tank (insoluble dirt (solid matter) remains) are returned to the base tank 2,
The processing drum is rotated at high speed to remove liquid, and the removed liquid is distilled by a distiller 7
To the condenser 8 and the water separator 9 to separate water (discard) and solvent (return to the rinse tank), and remove insoluble dirt as sludge.

Both agents in the base tank 2 are subjected to a distillation treatment after every several washings.

After the liquid is removed, the cleaning solvent is poured from the rinse tank 4 into the processing tank 1, rinsed, and again removed (to the base tank).

The dewatered clothes are sprayed with various processing agents from the processing agent tank 3 to be processed, dried, deodorized and finished.

The water repellent treatment is performed on a dried product.

Although the cleaning is performed generally as described above and other apparatuses are substantially the same, the conventional cleaning has the following problems, and its solution has been demanded.

Cleaning, deliquoring, rinsing
As in deliquoring-processing-drying, the number of steps is large and the time required for one cleaning is long, and therefore the number of cleanings per day is small and the efficiency is poor.

[0012] The amount of permanent solvent is about 400 liters, which is extremely large, and the amount of detergent consumed is a large amount such as an initial charge of about 1.2 liters and a main charge of about 8 liters. Since most of them are adsorbed by the adsorption filter centering on activated carbon, it tends to be in a state where washing is performed only with the solvent, which requires a large amount of detergent charge, which is extremely uneconomical.

Usually, dirt is classified into three types: water-soluble, oil-soluble, and insoluble (solid). However, conventional adsorption filters mainly using activated carbon mainly remove water-soluble dirt, and therefore, oil-soluble and insoluble. The stains are mainly distilled to remove the solvent as an evaporated residue.

However, the distillation treatment consumes heat and electric energy of a distiller, a condenser and the like, and the water separated by the water separator is a large amount of treatment in order to clear the pollution regulations such as removing the toxicity of the solvent. Because of the drawback of being expensive,
If possible, it is desired to reduce or eliminate the distillation treatment.

In the conventional washing, both agents in the processing tank used while circulating with the adsorption filter in the washing operation are once returned to the base tank at the end of the operation, so both agents in the base tank are not removed by the adsorption filter. Remained mixed, and the stains accumulated and accumulated at the bottom and corners of the tank, and they occasionally could not make up even if the tank was cleaned, causing a foul odor.

The ratio of the detergent in the treatment tank at the time of washing is about 4% as described above, which is a very high concentration, and therefore the amount of the detergent remaining on the clothes is large after the liquid is removed. However, there is a drawback in that the detergent once dipped in the solvent adheres to the clothes again during soaking operation, so-called reverse contamination occurs.

[0017]

SUMMARY OF THE INVENTION The present invention effectively solves the above-mentioned conventional problems by the following method and apparatus. That is, the present invention is a combination detergent containing a set weight of clothes in a treatment tank, rotating a treatment drum, and mixing a detergent mixture having a low affinity for clothing and a processing agent having a strong affinity for clothing. , Shower the solvent in the base tank at the same time until the specified level is reached,

When the designated water level is reached, the shower of both agents is stopped, and the treatment drum is rotated to wash and process the clothes, and as a first step, both agents in the treatment tank are circulated and fed only to the first filter (paper filter). And remove only insoluble dirt by filtration,

Subsequently, as a second step, while cleaning and processing are also performed by rotating the processing drum, both agents in the processing tank are circulated to both the first filter and the second filter (filter filled with ceramics and others). By sending it, the remaining insoluble, water-soluble, oil-soluble stains are decomposed and adsorbed and removed, the solvent is gradually cleaned, the effect of rinsing clothes is enhanced, and after the set time, only the clean solvent is used, The conventional problem is solved by the one-bath two-stage cleaning method, which is characterized in that the solvent is returned to the base tank by the liquid removal operation.

The one-bath two-stage cleaning apparatus used in the method of the present invention comprises at least a processing tank, a base tank, a first filter, a second filter, and a pump.

[0021]

EXAMPLES Next, the method of the present invention is applied to the apparatus of the present invention (see FIG. 1).
The operation and effect of the embodiment of the present invention will be described in combination with the description. The clothes of a set weight are put in the processing tank 1 and the processing drum is rotated, and a combination detergent, that is, a detergent having a low affinity to the clothes is used. A mixed detergent mixed with a processing agent having a strong affinity for clothes and a solvent in the base tank 2 are simultaneously showered until a designated liquid level is reached.

The designated liquid level means a detergent mixed with a minimum amount of detergent and a processing agent required for washing and processing clothes of a set weight in the processing tank 1, and a minimum required amount of solvent, that is, the same. Shows the liquid level when a solvent is injected to the extent that clothes can be evenly pickled by the rotation of the processing drum. It is a low liquid level when viewed from the past, and it is unique to the present invention for one-time cleaning in the present invention. The liquid level of both agents in the processing tank 1 is referred to as "designated liquid level".

The minimum required amount of detergent is, for example, the amount of detergent required only to remove 20 kg of clothes once, and the minimum required amount of processing agent is, for example, 1%. It means that the amount of processing agent becomes 0 when processing 20 kg of clothes (adhering to clothes). Then, once 20K
About 50 liters of solvent and about 15 blended detergents per g
Shower 0cc at the same time. That is, the ratio of the mixed detergent to the solvent is set to about 0.3%.

As the solvent, general perchlorethylene, petroleum-based solvent, fluorine-based solvent, trichloroethane, etc. are used, and the detergent is suitable for the solvent used, and in particular, it has a property with little affinity to clothes, that is, dirt. Mainly uses nonionic detergents (nonionic detergents, detergents that do not have an electric charge of +/-) that does not cause residue to adhere to clothes, and uses processing agents (softening agents, fluorescent agents, resin agents, antistatic agents). , Etc., except for water repellents) are mainly anionic processing agents that are compatible with the solvent used and the detergent, and that have a particularly strong affinity for clothing, that is, that they adhere well to clothing. (-Ionic processing agent) is used.

Next, the shower of both agents is stopped when the designated water level is reached, and the clothes are washed and processed by rotating the processing drum,
As a first step, both agents in the treatment tank are treated with the first filter 10
Only the (paper filter) is circulated and fed by the pump 5 to remove only insoluble dirt by filtration.

Since the first filter 10 is a paper filter, it effectively removes insoluble dirt, that is, solid matter (dust, fiber waste, etc.) by filtration, but it passes the solvent and the blended detergent as they are without adsorbing them. As a result, since the detergent was circulated in the adsorption filter at the same time as the start of washing in the related art, the detergent was adsorbed to the adsorption filter before the washing was completed and the washing effect of the detergent could not be sufficiently exerted.

Then, as a second step, when the cleaning action by the detergent is almost achieved, the two agents in the processing tank 1 are treated with the first filter 10 and the second filter while cleaning and processing are also performed by rotating the processing drum. It is circulated and sent to both filters of 11, and the remaining insoluble stains, water-soluble and oil-soluble stains, deteriorated detergents, fatty acids, pigments, moisture, etc. are adsorbed and removed, and the solvent is gradually cleaned to remove clothes. The effect of rinsing is enhanced, and after the set time, only the clean solvent is left, and the solvent is returned to the base tank by the liquid removal operation.

The second filter 12 is filled with various porous ceramics, activated carbon, deoxidizer, etc.,
It decomposes and removes water-soluble stains, oil-soluble stains, deteriorated detergents, etc. generated by washing. Therefore, the second
By circulating both agents through the first and second filters at the same time in the stage, all the stains are gradually removed from both agents (note that the processing agent is attached to the clothing and consumed by the processing action).
Since it becomes progressively cleaner solvent only, that is to say it has an effective rinsing action, thus eliminating the rinsing step, which was conventionally a separate step.

Further, as described above, since the non-ionic detergent having a low affinity is used as the detergent, the stains on the clothes can be removed efficiently, but the detergent does not adhere to the clothes and, on the contrary, Since the processing agent used is an anionic processing agent having a strong affinity, it effectively adheres to soiled clothes, and here, one-bath cleaning can be completely achieved.

After the liquid is removed, a drying treatment is carried out and, if necessary, a water repellent agent is sprayed to carry out a water repellent treatment. That is, unlike the prior art, it can be performed without a rinsing step.

In addition to the above, the present invention has the following outstanding advantages over the prior art. 1 bath (only the first two injections)
Since the number of steps is smaller than before, such as two-step (first and second steps) cleaning, processing-dewatering-drying-water repellent processing, the cleaning time per operation is reduced to about 1/2 of the conventional method. obtain.

Since no initial charge is required, the amount of detergent can be saved. Further, since the detergent concentration is as low as about 0.3%, the detergent charge amount for each washing can be significantly reduced. Also, there is no risk of reverse contamination.

Due to the short contact time between clothes and detergent,
Less likely to damage the texture of clothing.

Since a detergent having a low affinity is used, the residual detergent for the clothes is extremely small, and the detergent having a strong affinity is used for the good processing, the new feeling of the clothes can be maintained.

Except for the case of special cleaning, the distillation treatment could be dispensed with in the ordinary cleaning, so that the scraping of the residue and the control of waste water pollution of the separated water became almost unnecessary.

As in the prior art, since the solvent (which also contains dirt) once used for cleaning is not returned to the base tank, dirt is settled in the base tank to give off a bad odor, and the cleaning is performed. There is no such thing.

The one-bath two-stage cleaning apparatus used in the method of the present invention comprises at least a processing tank, a base tank, a first filter, a second filter, and a pump.

[0016]

EXAMPLES Next, the method of the present invention is applied to the apparatus of the present invention (see FIG. 1).
The operation and effect of the embodiment of the present invention will be described in combination with the description. The clothes of a set weight are put in the processing tank 1 and the processing drum is rotated, and a combination detergent, that is, a detergent having a low affinity to the clothes is used. A mixed detergent mixed with a processing agent having a strong affinity for clothes and a solvent in the base tank 2 are simultaneously showered until a designated liquid level is reached.

The designated liquid level means a detergent mixed with a minimum amount of detergent and a processing agent required for washing and processing clothes of a set weight in the treatment tank 1, and a minimum required amount of solvent. Shows the liquid level when a solvent is injected to the extent that clothes can be evenly pickled by the rotation of the processing drum. It is a low liquid level when viewed from the past, and it is unique to the present invention for one-time cleaning in the present invention. The liquid level of both agents in the processing tank 1 is referred to as "designated liquid level".

[0018] Incidentally, the required minimal metric detergents, for example, a detergent amount as necessary to take the dirt once portion of the garment (set weight), also with the required minimum metric of the processing agent, ,
Also for example, in the processing of one portion of the garment (attached to clothing) is that amount of processing agent becomes zero.

As the solvent, general perchlorethylene, petroleum-based solvent, fluorine-based solvent, trichloroethane, etc. are used, and the detergent is suitable for the solvent used, and in particular, it has a property with little affinity to clothes, that is, dirt. Knock but using detergent properties that do not adhere remaining garment, processing agents (softeners,
Various processing agents such as fluorescent agents, resin agents, antistatic agents, but excluding water repellents. ) Is used with those adapted for use solvents and detergents, especially strong nature affinity for clothing, i.e. the pressurized Engineering agent property of adhering well to the garment.

Next, when the designated water level is reached, the shower of both agents is stopped, and the treatment drum is rotated to wash and process the clothes,
As a first step, both agents in the treatment tank are treated with the first filter 10

Since it becomes progressively cleaner solvent only, that is to say it has an effective rinsing action, thus eliminating the rinsing step, which was conventionally a separate step.

Further, as described above, since the detergent uses a detergent having a property of low affinity, it can effectively remove stains on clothes, but the detergent does not adhere to the clothes and, conversely, is processed. As the agent uses a processing agent with a strong affinity, it will efficiently adhere to dirty clothes,
Here, one-bath cleaning can be completely achieved.
