Abstract

PURPOSE:To miniaturize the whole body of an equipment and to easily attach and detach a member by constituting the title filtering purification tank of both a filter cylinder freely detachably fitted to a projected water feed port and a water permeable closed-end double cylindrical vessel which is concentrically positioned to the outer periphery thereof and incorporates activated stone therein as essential parts. CONSTITUTION:A filter cylinder 7 is formed by sticking a filter 9 made of bellowslike filter paper, etc., on the outer peripheral surface of a perforated tubular filter core 8 whose inside is used as a water channel 7a. On the other hand, a closed-end double cylindrical vessel 12 is made of plastic and stainless steel and the channel holes 13a, 14a are bored to the inner wall 13 and the outer wall 14 and also activated stone 16 is packed in the containing space 17 thereof. Both the filter cylinder 7 and the vessel 12 containing activated stone are held with a cover plate 4. Therein bathtub water sucked by a pump is passed through the water channel 7a of the center of the filter cylinder from a water feed port 5 and filtered with the filter 9 and thereafter introduced into the vessel 12 incorporating activated stone, activated and purified and then introduced into a bathtub through a discharge pipe 6 and circulated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filtration and septic tank that serves as both a filtration tank and a septic tank in an apparatus for circulating and purifying bath water.

(Prior Art) A device for circulating and purifying hot water in a bathtub is constructed by connecting a circulation pump, a filter tank, an activated stone tank for purification, an auxiliary heater, and a sterilization device in series.

The disadvantage of this conventional device is that the devices are connected in series on a plane, making the device large in size relative to its processing capacity.

Further, since the effective period of the filter tank, that is, the time to replace it and the time to clean the purifying agent (activated stone) are different, the work must be done for each device, which is inconvenient.

That is, the filter member generally has a thickness of 2 to 3 depending on the usage condition.
It needs to be replaced every month, and activated stones need to be cleaned every 3 to 6 months.

On the other hand, in the conventional apparatus, since these tanks are separate, maintenance work must be performed for each tank.

Furthermore, the filter tank and the septic tank are the largest of the devices that make up the device, and the size of the device is determined by them.

The purpose of the present invention is to make the overall size of the device extremely small, and to simplify the installation and removal of filter members and/or activated stones into and from the tank. .

(Configuration) The filtration septic tank of the present invention has a water supply port connected to a hot water circulation path protruding upward at the bottom of the tank, a discharge pipe on the side wall of the tank, and a lid plate that can be opened and closed at the top of the tank. a storage tank, a filter cylinder removably fitted into the protruding water supply port, and a bottomed double cylindrical container that is placed concentrically around the outer periphery and has water-permeable inner and outer walls and is filled and accommodated with activated stones. , upper surfaces of the filter tube and the bottomed double cylindrical container are in direct or indirect contact with the lid plate.

Furthermore, filterability 1 consisting of a filter cylinder and a bottomed double cylindrical container
A plurality of sets of cylinders are connected in parallel and housed in a common storage tank.

In addition, if necessary, it is possible to store a disinfectant in a filter cylinder or activated stone container, and it is also possible to install a disinfectant or known sterilization means in a tank for further miniaturization. It is. In addition, an auxiliary heat source can be incorporated into the tank, making the device even more compact.

(Effects) With the above configuration, the filter cylinder and activated stone storage container can be attached and removed at the same time or separately, and when multiple filtration and purification cylinders are installed in parallel, the filter area is expanded and the liquid flow resistance is increased. This has the effect of reducing the pump capacity and extending the effective life of the filter.

Furthermore, since both the filter tube and the activated stone container can be made smaller, that is, the height of the tube can be lowered, there is an advantage that cleaning, replacement, attachment and detachment of each can be carried out more easily.

(Example) (1) is the tank, (2) is the tank side wall, (3) is the bottom,
(4) is a lid plate.

(5) is a water supply port that projects upward from the bottom of the tank and has sealing means on the outer periphery, and (6) is a drain pipe.

(7) is a filter cylinder, which is formed by fixing a filter (9) made of bellows-shaped filter paper or a felt-like substance to the outer peripheral surface of a tubular porous filter core (8) whose interior serves as a passageway (7a). ing.

(10) is a soluble bactericidal agent, such as a silver ion eluting substance, which is stored as required.

(11) is a lower packing and is not necessarily required.

(12) is a bottomed double cylindrical container made of plastic or stainless steel, and its inner wall (13) and outer wall (14) are perforated with water holes (13a) and (14a). (15
) is the bottom, (16) is the activated stone, and (17) is the storage space.

The container (12) can be made of metal, wire mesh, or the like, as long as it retains its shape.

(18) is the upper packing and is not particularly necessary9.The fitting form between the water supply port and the filter core may be either male or female.

In the above device, hot water sucked in by a pump (not shown) flows from the water supply port (5) to the center of the filter tube through the water passageway (7).
a), is filtered by a filter (9), and is immediately introduced into an activated stone container (12) on the outer periphery, where organic substances are adsorbed and minerals are eluted, and active purification is carried out through a discharge pipe (6).
Go inside the bathtub.

Figure 2 shows the filter tube (7) and activated stone storage container (12).
This is another embodiment of a storage tank suitable for arranging a plurality of sets of filtration and purification cylinders (20) concentrically arranged in parallel. Tanks or common ducts (21) are installed in series, thereby eliminating piping to each water supply port (5) and reducing costs.

Furthermore, in order to easily hold the filtration purification barrel 20) in the tank and take it out, a holding barrel (22) is provided upright on the lid plate (4), and the lid member <23) is attached to the cup link pant (2).
4) makes it watertight.

When such a disaster occurs, increasing the height of the storage tank reduces the retention volume of purified hot water and increases the circulation efficiency of hot water.
