Abstract

PURPOSE:To treat water with an ion-exchange resin even when the device main body is set not vertically and to reduce the setting space of the main body by forcing an ion-exchange resin and a sponge to press the resin into a columnar vessel. CONSTITUTION:The lower part of a cylinder 9 is closed by a lower cap 12, and an ion-exchange resin is packed in the cylinder to the upper part of the cylinder to constitute a simplified water treating device 3, e.g. a simplified water softening device. A columnar sponge 7 is placed on the open surface 10, the sponge 7 is covered with a presser plate 14 with its opening for water turned upward, and the upper part of the cylinder 9 is closed by an upper cap 13. Namely, the ion-exchange resin is pressed by the sponge 7, and the sponge 7 is expanded as the resin is contracted to prevent the formation of a space. Consequently, water is treated even if the device 3 is set not vertically, and the setting space is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple water treatment device which is directly connected to a water supply pipe to soften hard water or filter water.

[0002]

2. Description of the Related Art When it is necessary to remove hardness components in feed water such as in a boiler, soft water treated through a water softening device using an ion exchange resin is used. Ion exchange resin needs to pass salt water periodically to be regenerated, and the water treatment equipment is equipped with a salt water tank, control valve, drainage pipe, etc. in addition to the resin tower containing the ion exchange resin. , Is played regularly. However, in the case of small-scale equipment using soft water, it is often not possible to install a normal water softening device from the viewpoints of cost and space, so a simple water softening device simply filled with an ion exchange resin in a columnar container. Is inserted into the water supply pipe, and when the capacity of the resin decreases, the water softening device is replaced with the water softening device, or a simple water softening device is used in which only the ion exchange resin is replaced. Further, by using a device similar to the simple water softening device, it is used as a filtering device by filling the inside with a filter medium to provide a filtering function.

When a simple water treatment device is manufactured, a treatment material for softening or filtering is put up to the upper end of the cylinder, but when water is put in the water treatment device and the water is passed, the treatment material sinks, There is a space above the processor. When the water treatment equipment is installed vertically, soft water or filtered water can be obtained because the treatment material settles and a space is created in the upper part of the equipment, so that there is no bias in the treatment material layer. When the device is installed horizontally or diagonally, the treatment material settles out in the form as shown in Fig.3, and the water flows a lot to the portion of the treatment material layer with less resistance, and sufficient ion exchange or filtration cannot be performed. There is. Therefore, the installation direction of the water treatment device must be limited to the vertical direction, which has been an obstacle in reducing the size of the entire device.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to allow a simple water treatment device directly connected to a water supply pipe to be installed in a direction other than the vertical direction.

[0005]

[Means for Solving the Problems] When one end of a columnar container having a hollow inside is closed and a treatment material for softening or filtering is filled from the other end side, the treatment material is put up to the upper end of the columnar container, Further, a sponge is put on the upper part of the container, and the sponge is compressed in the lengthwise direction of the container and hermetically sealed. In addition, put a cap-shaped sponge holding plate with an opening for water passage on the upper surface over the sponge so that the opening for water passage is on top and put it in the columnar container, and compress the sponge. Seal tightly.

[0006]

Function: The sponge can be reduced in volume by being compressed, and the compressed sponge exerts a force to restore it, so that the sponge presses the treatment material. When the treatment material in the water treatment device sinks, the sponge put together with the treatment material swells by the amount of the sedimentation, so that no space is generated. Therefore, even if the water treatment device is not installed vertically, the sponge swells and the top surface of the treatment material settles while remaining parallel to the container opening surface, and there is no deviation in the thickness of the treatment material layer, allowing water to pass through. Water passes through the treatment material layer having a uniform thickness, so that soft water or filtered water can be collected. When the sponge is covered with a pressing plate and placed in a columnar container, the sponge can be easily aligned and the displacement of the sponge can be prevented.

[0007]

The present invention will be described with reference to the drawings. FIG. 1 is an exploded view of an embodiment of the present invention. Simple water softening device (3)
The lower part of the cylindrical cylinder (9) to the lower cap (1
Block with 2) and fill the cylinder with the ion exchange resin (6) to the top. Cylindrical sponge (7) on resin
The cap-shaped sponge holding plate (14) having the water passage opening (11) on its upper surface is covered with the water passage opening side up and is covered with the upper cap (13).
When closing the upper cap, the resin is filled up to the uppermost portion, so that the cylindrical sponge is compressed in the length direction of the container. The compressibility of the sponge can be adjusted by the thickness of the sponge, and the sponge may be further compressed after passing water, or a sponge that expands when water is included may be used. Even in the case of a water softening device packed with sponge, the resin settles by passing water, but the compressed sponge acts to restore it, and the sponge becomes a cylindrical shape as much as the resin settles. In order to swell, the top surface of the resin settles parallel to the cylinder opening surface (10). Since the resin portion settles in a cylindrical shape, even if the water softening device is installed in an oblique direction, the thickness of the resin layer does not deviate, and the water that is passed through is softened uniformly.

FIG. 2 shows a flow of an example of using the simple water softening device of the present invention. Simple water softening device (3),
In the water supply pipe (2) provided with the water supply tank (4) and the water supply pump (5) and connected to the boiler (1), even if the simple water softening device is installed in an oblique direction, a columnar shape is provided inside the softening device. Since the sponge is packed, the boundary of the resin portion becomes parallel to the cylinder opening surface, and the resin settles in a cylindrical shape. The raw water that has been passed from the sponge side in the softening device passes through the cylindrical resin layer, the hardness is removed, and the water becomes soft water and is supplied to the boiler.

FIG. 3 shows the state of sedimentation of the ion exchange resin when the conventional simple water softening device is installed horizontally and diagonally. The space (8) where the resin settles and the resin disappears is created from a higher place in the softening device. When installed horizontally, the space where the resin settles can be extended from the upstream side to the downstream side in the water softening device. If water is passed in that state, a large amount of water will flow into the space with low resistance, and the water flowing through the upper space will not be ion-exchanged, so water will be supplied with the hardness remaining. Even when the water softening device is installed diagonally, the upper surface of the resin is horizontal and the thickness of the resin layer varies depending on the location. In this case, too, water flows to a thin part of the resin with low resistance,
This will cause hardness leakage.

The same applies to the case where a filter medium is packed instead of the ion exchange resin, and when the filter device is installed in an oblique direction, when the sponge is packed, filtered water is obtained without biasing the filter medium, and without the sponge, the filter medium is However, the filtration becomes insufficient due to a bias.

[0011]

By implementing the present invention, the simple water treatment device can be installed in a direction other than the vertical direction, and the restrictions on the installation space are reduced. Therefore, the space can be used effectively. The water treatment device can be installed in a place where the whole device can be compacted, and the entire device can be downsized.
