Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a moisture removal device for dry cleaning, which removes moisture in a solvent by absorbing it into a water absorbent.

[Technical background of the invention and its problems]

In dry cleaning, in order to make it easier to remove water-soluble stains from the items to be washed, a drying detergent and water are added to the solvent in accordance with the respective standards, and cleaning is carried out while maintaining an appropriate solvent temperature.

However, depending on the season, the items to be washed may contain a lot of water, so if the amount of water added is not appropriate and the water content is increased more than necessary,
The solvent becomes cloudy and emulsified water separates.

Washing under such conditions will cause the items to be washed to shrink,
Problems such as stains may occur, and there is also the risk of mold and yellowing due to residual moisture on clothing.

Conventionally, a device as shown in FIG. 1 has been used to solve this problem. In Figure 1, 1 is a washing tank, 2 is a solvent tank, 3 is a solvent pump, 4 is a filter, 5 is a distiller, 6 is a cooler, and 7
is a water separator, and normally a circulation is performed in which the solvent is pumped up from a solvent tank 2 with a pump 3, passed through a filter 4, and injected into the washing tub 1 from a solvent injection nozzle 8, and then returned to the solvent tank 2. ing. And if the water content in the solvent increases,
The solvent is sent to a distiller 5 where it is vaporized and then passed to a cooler 6.
The method used was to liquefy the solvent, separate it into water and solvent in a water separator 7, and return only the solvent to the solvent tank 2. However, water separation may be insufficient and the water may return to the solvent tank 2 together. In this case, the solvent must be redistilled, which is not only time-consuming but also expensive. In addition, for devices not equipped with a water separation mechanism as described above, there is a method of adsorbing and removing excess water by washing something that easily absorbs water, such as a cotton towel basket, in the washing tub, but this method is not efficient. That wasn't a good way to do it.

[Purpose of the invention] In view of the above-mentioned problems, the present invention provides a water absorption tank that introduces solvent from a solvent tank and absorbs water, and stores a plurality of water absorption cylinders in this water absorption tank through liquid passage gaps. However, the solvent is caused to flow from the outer periphery toward the center of the water-absorbing cylinder to absorb and remove moisture in the solvent.

[Summary of the idea]

The present invention consists of a washing tub into which solvent is sprayed, a solvent tank that collects the solvent from the washing tub and sends it back to the washing tub via a filter, and a solvent tank that collects the solvent from the washing tub and sends it back to the washing tub through a filter. It consists of a water absorbing tank containing a water absorbing body that absorbs water by passing through it, and the water absorbing body is fitted with a plurality of water absorbing cylinders made of water absorbing fibers arranged concentrically with gaps between them and the outermost periphery. It consists of a bellows-shaped paper tube that absorbs moisture in the solvent.

In the water absorbing body 31, a plurality of water absorbing tubes 36 of different diameters are arranged concentrically on the outer periphery of a liquid passage pipe 35 forming a liquid passage passage 34 at the center, with a liquid passage gap 37 interposed therebetween, and a liquid passage gap is formed on the outermost periphery. A paper tube 39 formed in a bellows shape in the circumferential direction is provided via a tube 38, and the upper and lower sides are supported by a lid plate 42 and a bottom plate 43 having annular projecting edges 40 and 41, respectively, and a liquid passage tube in the center.

A wing nut 55 is screwed onto 52 to press the water absorbent body 31 onto the support plate 32.

Furthermore, a guide plate 56 is interposed between the inner wall of the moisture absorption tank 26 and the outer periphery of the water absorbing body 31, facing the opening of the liquid feeding pipe 28 opened in the peripheral wall of the moisture absorption tank 26.
The inflow liquid from the liquid sending pipe 28 is designed not to directly collide with the water absorbing body 31.

Next, the operation of the above embodiment will be explained.

During normal cleaning, open valve 13 and open valve 2.
7 is closed and the solvent is circulated through the solvent tank 2, solvent pump 8, filter 4, solvent injection nozzle 8, and washing tub 1 to perform washing.

Next, if the amount of water in the solvent increases and the solvent becomes cloudy or emulsified, or if you want to remove water periodically to suppress the increase in water, first use the solvent tank 2, solvent pump 8, distillation The solvent is circulated in the vessel 5, the cooler 6, and the water separator 7 to separate water. If water that has not been further separated remains in the solvent, the valve 27 is opened and the valve 13 is closed to circulate the solvent through the solvent tank 2, solvent pump 8, filter 4, and water absorption tank 26. At this time, water in the solvent is absorbed and removed by the water absorption layer 49 made of water absorption fibers provided in several layers during the process in which the solvent flows from the outer periphery to the inside of the water absorption body 31. 34 to the bottom of the water absorption tank 26, and returns to the solvent tank 2 through the return pipe. After the water absorption layer 49 has absorbed some water, the water absorption body 31 is taken out from the water absorption tank 26 and replaced with a new water absorption body 31. A bellows-shaped paper tube 39 is provided on the outermost periphery of the water absorbent body 31.
There is also a filter 4 in front of the water absorption tank 26.
Because it passes through the water, solvent contamination does not have a negative effect on the water absorption capacity. Since the plurality of water absorption tubes 36 are arranged concentrically with the liquid passage gaps 37 interposed therebetween, high water absorption capacity can be obtained without increasing the pressure of liquid passage.

FIG. 5 shows another embodiment without a water separation mechanism. The structure and operation of the washing mechanism and moisture absorption mechanism are the same as in the previous embodiment.

[Effects of the invention] According to the invention, a washing tub into which a solvent is sprayed;
It consists of a solvent tank that collects the solvent from the washing tub and sends it back to the washing tub, and a water absorption tank that houses a water absorbent that absorbs water by passing the solvent sent from the solvent tank from the outer periphery toward the center. , the water absorbent body is composed of a plurality of water absorbing tubes made of water absorbing fibers arranged concentrically with gaps in between and a bellows-shaped paper tube fitted on the outermost periphery, so that the solvent that has absorbed the water depth is By passing the solvent through a moisture absorbing tank, the water absorbing cylinder made of water absorbent fibers absorbs the moisture in the solvent and allows only the solvent to pass through, making it possible to easily remove the moisture in the solvent. In addition, since a bellows-shaped paper tube is inserted into the outermost periphery of the water absorbent body, the dirt in the solvent is passed through the paper tube, preventing dirt from adhering to the water absorption tube. The water absorbency of the cylinder is not impaired. Furthermore, when the water absorbing cylinder has absorbed a certain amount of water, the water absorbing body can be taken out from the water absorbing tank and replaced with a new one, thereby preventing a decrease in the water absorbing capacity. Furthermore, since the structure of the water absorbing body is simple, it is easy to manufacture and the water absorbing tube can be easily replaced.
