Description

[Detailed Description of the Invention] The present invention uses a Neso conveyor to transport soiled clothes, etc. to i! L
The present invention relates to a method and apparatus for dry cleaning while transferring the same.

B. Prior Art Conventionally, when dry cleaning dirty clothes, etc., the clothes, etc. are placed in a washing drum of a cleaning device, and then a large amount of solvent solution is flowed into the washing drum to wash the clothes, etc.
When washing is completed, the solvent solution is discharged, the washed clothes are dehydrated and dried, and then the clothes are taken out from the washing drum. However, with this method, the solvent solution flows into the washing drum to wash clothes, etc.
There is a drawback that the dirt removed from the clothes contaminates the solvent solution, and therefore, by the time washing is finished, the dirt in the contaminated solvent solution re-adheres to the clothes etc. Therefore, in order to prevent the dirt in the solvent solution from re-adhering to clothes, etc., attempts have been made to remove the dirt in the solvent solution using a filter or completely remove the fluid by centrifugation. It is difficult to prevent the re-adhesion of dirt with equipment. Furthermore, the conventional apparatus has the disadvantage that unreasonable mechanical force is applied to the clothes and the like by stuffing them into the washing drum, causing them to twist and shrink, causing them to lose their shape or become deformed. Furthermore, even if clothes and the like are completely dried, the smell of the solvent remains, and there is a problem in that the residual solvent odor worsens the surrounding environment.

), the Tough I nozzle (35) is a heating heater, and (36) is a blower, which blows hot air through the duct nozzle (34). Spray onto the treated material (2) and let it dry.

The deodorizing mechanism (5) is for removing the solvent liquid remaining on the object to be treated (2) such as clothes. That is, since the object to be treated (2) is washed by being immersed in the solvent /& (9), it contains the solvent upon completion of washing. The solvent contained in the object to be treated (2) is removed by a deliquifying mechanism (3) and a drying mechanism (
4) is completely removed. However, even if the object to be treated (2) is completely dried by the drying mechanism (4), the smell of the solvent remains inside the object to be treated (2). If the object to be treated (2) with residual solvent odor is taken out as it is, the smell of the solvent will gradually come from the object to be treated (2) and deteriorate the surrounding environment. In order to prevent this, a deodorizing mechanism (5) was provided following the drying mechanism (4).

In the deodorizing mechanism (5), (37) is a duct nozzle arranged vertically opposite to each other via the processed material conveying part (32a) of the transfer net conveyor (32), and (3B) is a duct nozzle (37). ), the blowers (38) blow room-temperature air through the duct nozzle (37) onto the dried workpiece (2), and the Removes solvent odors.

Incidentally, (39) is a duct for discharging the solvent vapor caused by natural evaporation around the cleaning mechanism (1) and the dehydrating mechanism (3) together with air by a blower to maintain the working environment around the apparatus. (40) is a duct for simultaneously discharging internal solvent vapor and external air in order to prevent the highly concentrated solvent vapor in the drying mechanism (4) from directly blowing out to the outside.

The hot solvent air is then led to the solvent recovery device through the ducts (39) and (40) and treated.

Next, the procedure for dry cleaning objects to be processed such as clothes will be explained as follows.

The new solvent solution (9) is continuously supplied to the washing tank 4W (8), which is a high liquid level tank, and the solvent solution (9) is sequentially supplied to the washing tanks (7) and (6), which are low liquid level tanks. At the same time, the pump (11) is driven and each washing tank (
6) Forcibly move the solvent solution (9) in (7) and (8).

The object (2) to be treated, such as dirty clothes, is placed on the carrying-in portion (<13b) of the transfer net conveyor (13) that circulates 1#. As the transfer net container (13) moves, the object to be treated (2) is sequentially immersed in each washing tank (6), (7), and (8) in a direction opposite to the flow direction of the solvent solution (9). -) Wash at the transfer stage. That is, the object to be processed (2) is conveyed through a net conveyor (13) for transport and a net conveyor (1) for holding.

), followed by tertiary washing. During the first to third cleaning, the solvent solution (9) in each cleaning tank (6), (7), and (8) is forcibly moved by the pump (11), so the object to be treated (2) vibrates and its Washing efficiency is increased. In addition, the dirty workpiece (2) is transferred in the opposite direction to the flow direction of the solvent solution (9), and is washed with a new solvent solution (9) as it undergoes primary washing, secondary washing, and tertiary washing. will be done. The solvent solution (9) naturally flows down from the tertiary cleaning tank (8) to the secondary and primary cleaning tanks (7) and (6) in sequence, while the dirty workpiece (2) first flows down into the secondary and primary cleaning tanks (7) and (6). After being washed in the next washing tank (6), it is subjected to the second and third washing, so the dirty solvent solution (9) flows down each washing m4fl (8) (7) by gravity and finally The dirt overflows from the dirtiest primary washing tank (6) and is naturally discharged into the drain groove (10). Therefore, the dirt removed from the object to be treated (2) during the first to third cleanings will not re-adhere to the object to be treated (2).

In addition, each washing tank (6) (7) (8) of the above-mentioned 1st to 3rd washing d.
) A squeezing roll may be provided between the two to once squeeze the object (2) and then send it to the hot washing tank. However, it is also possible to produce a squeezing effect by using the clamping pressure of the net-con hair without particularly providing a squeezing roll.

The object to be treated (2), which has been washed in this way, is removed by the dewatering mechanism (3).
) where it is dehydrated. That is, the washed workpiece (2) is held between the discharge part (13b) of the transfer net conveyor (13) and the auxiliary net conveyor (20), and is held between the suction box (22) and the divided pressurizing port (2). 23
), and during this passage, the succidine box (
The liquid is removed by the suction force acting on 22). At this time, since each divided pressure roll (23) is individually pivotally supported for eccentric rotation, the divided pressure roll (23) rotates in accordance with the thickness of the workpiece (2) to be processed. Processed material (2)
Pressurize. Therefore, the suction [] of Zakujonhox (22) is indirectly obstructed; H, U sap is significantly improved. In addition, in areas where there is no object to be processed (2), the divided pressure roll (23) directly blocks the suction port of the suction box (22) by pulling the hair net, thereby improving the deliquing efficiency. is extremely good.

The deliquified workpiece (2) is sent from the transfer conveyor (13) to (32), which causes the drying mechanism (
4). Then, the heated air heated by the heating heater (35) is blown by the blower (36) through the duct nozzle (34) onto the object to be processed (2) being transferred. ) is dried with hot air.

The object to be treated (2) thus dried with hot air is transferred to the deodorizing mechanism (5) by the transfer net conveyor (32).

In the deodorizing mechanism (5), the rotation of the blower (38) causes room temperature air to flow through the duct nozzle (37) to the object to be treated (
2) is sprayed rapidly. By blowing this room temperature air, the solvent odor that was present inside the object to be treated (2) is completely wiped away.

FIGS. 6 and 7 show other embodiments of the cleaning mechanism (1). In this example, the washing tank (41) (41)
The liquid level of the solvent liquid (9) in (41) is the same, and the solvent liquid (9) is forcibly moved using pumps (42) (42) (42). be. .

Although three washing tanks were provided in the above embodiment, the present invention is not limited to this, and two or more washing tanks may be provided, and the number may be changed as necessary.

Effects of the Invention According to the present invention, clothes, etc. are continuously transferred using a net-con hair, and washed by being immersed in a solvent solution that naturally flows down in the direction opposite to the direction of transfer of the clothes, etc. during the transfer route. After that, L7 removes liquid, dries, and deodorizes, so it removes fihl from clothes etc.
The dirt that has been removed will not stick to the clothes again. In addition, since a net conveyor is used, there is no need for excessive mechanical force to be applied to clothes, causing them to twist or shrink, which is the case in the past, and this prevents clothes from losing their shape or deforming. I can do it. Furthermore, since the liquid is removed while applying pressure to clothes etc. using 1M divided pressure rollers that rotate according to the thickness of the clothes, the dewatering efficiency is extremely high. Further, the smell of the solvent does not remain on clothes, etc., and the surrounding environment does not deteriorate.
