Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a pool water filtration device and a filtration system, and in particular, to a pool water filtration device and a filtration system, in particular, a tank for storing a filter medium or a filter device is divided vertically, and can be divided in normal times. When using a lower tank to improve filtration performance or when adopting a new filtration system, an upper tank can also be used.

BACKGROUND OF THE INVENTION With the recent fitness boom, swimming has become popular as a full-body exercise most suitable for improving health and relieving stress, and is enjoyed by a wide range of people from infants to the elderly. Accordingly, the number of swimming pools is increasing from public ones to private ones such as sports clubs. Along with this, there is a growing interest in the sanitary conditions of swimming pools, especially the purification equipment that determines the water quality. This is particularly the case in warm water pools, where the pool water is contaminated by bacteria propagated or mixed with human sweat, tongue, spittle, hair, etc., resulting in a deterioration of the water quality. Therefore, a pool water filtration device is used as equipment for purifying pool water, but generally a method combining sand filtration and chlorine sterilization is used. Recently, ultraviolet sterilization methods, ozone treatment methods, methods using ceramic filters, and activated carbon filter media have been used, and efficient filtration has also been achieved by appropriately combining these methods. .

Problems to be Solved by the Invention However, immediately changing the filtration system currently used in an existing pool to a completely new filtration system as described above is a huge economic burden, and it is difficult to manage the sports club. It will be threatening.

Therefore, the present invention provides a pool water filtration device and a filtration system that allow easy introduction of another filtration system into the filtration system currently in use.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention consists of a lower tank and an upper tank that are vertically divisible and each has a water supply pipe and a drain pipe separately installed. The drain pipe of the tank can be connected to the water pipe of the lower tank, and both tanks can be divided vertically with a pool water filtration device that houses filter media or filters that have a pool water filtration function independently. It consists of a lower tank and an upper tank, each with a separate water supply pipe and drain pipe.The lower tank houses a filter medium or filter and is used for pool water filtration during normal times. When increasing water filtration performance, or when using a new filter medium or filter, store the filter medium or filter in the upper tank and connect the drain pipe of the upper tank to the water pipe of the lower tank. The pool water filtration system is configured so that the upper tank is used in combination with the lower tank.

Function Under normal conditions, pool water is sent into the lower tank from the water pipe, and the pool water is filtered by the filter material in the lower tank, purified, and returned to the pool. If you want to improve the filtration function of pool water or need to use a new filter medium or filter, store the same filter medium or filter in the upper tank as the lower tank, or install a new filter medium or filter. After storing the upper tank, connect the drain pipe of the upper tank to the water pipe of the lower tank, and send the pool water to the water pipe of the upper tank, so that the pool water is filtered by the filter medium or filter in the upper tank. After that, the water is sent into the lower tank, where it is cleaned again by the filtering action of the filter medium or filter housed in the lower tank, and then returned to the pool.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Figure 1, pool water filtration device 1
consists of a lower tank 2 and an upper tank 3 that are connected in a vertically separable manner.The lower tank 2 is connected to a water pipe 5 and a drain pipe 7, and the upper tank 3 is connected to a water pipe 4 and a drain pipe 6. is connected. A filter medium 8 such as sand or activated carbon is stored in the lower tank 2 so that the pool water introduced from the water pipe 5 passes through the filter medium 8 and returns to the pool via the communication hole 9 and the drain pipe 7. It's summery. The upper tank 3 has a portion 1 that constitutes the lid of the lower tank 2.
0, a portion 12 connected to the portion 10 via the joint portion 11, and the portion 12 and the joint portion 13.
and a portion 16 that is connected to the portion 14 via a joint portion 15. The portion 16 constitutes the lid portion of the tank 3. A water pipe 4 is connected to the portion 12, a drain pipe 6 is connected to the portion 10, and a plurality of filters 17 such as ceramic filters are connected to the water pipe 4. That is, in the lower tank 2 and the upper tank 3, filter media or filters each having a pool water filtration function are housed independently. The operation of this pool water filtration device 1 will be explained below. First, during normal times, only the lower tank 2 is used to filter pool water. In this case, operate the water pump not shown in the diagram.
By sending the pool water into the lower tank 2 from the water supply pipe 5, the pool water is purified by the filtration action of the filter medium 8, and is returned to the pool via the communication hole 9 and the drain pipe 7. At this time, the upper tank 3 is not used at all.

Next, if you want to increase the filtration function of the pool water or use a new filter, store the new filter 17 in the upper tank 3 and connect the drain pipe 6 of the upper tank 3 to the lower part. Water pipe 5 of tank 2
A water pump (not shown) is operated to send pool water to the water pipe 4 of the upper tank 3. Then, the pool water is filtered by the plurality of filters 17 in the upper tank 3, and then sent into the lower tank 2 from the drain pipe 6 via the water pipe 5, and stored in the lower tank 2. The water is cleaned again by the filtration action of the filter medium 8, and is returned to the pool via the communication hole 9 and the drain pipe 7. New filters refer to sand filters, which will be described later, and filter media that will be developed in the future.

Therefore, a new filter medium or filter can be installed in the upper tank 3 while using the existing lower tank 2. Furthermore, the filtering action can be performed independently by the upper tank 3 without using the lower tank 2. Furthermore, when replacing the filter medium or filter in one tank, it is also possible to carry out the necessary replacement work while performing the filtration action only in the other tank.

When replacing the filter medium 8 in the lower tank 2, the upper tank 3 is removed and the replacement work is performed. In addition, when replacing the filter 17 in the upper tank 3 with another new one, the upper tank 3
Remove the part 16 that constitutes the lid of the filter 1.
7 replacement work will be carried out.

In FIG. 2, a sand filter 18 is used instead of the filter 17 disposed in the upper tank 3, and
An example is shown in which a filter material is stored under the sand filter 18.

Effects of the Invention According to the present invention described above, pool water can be filtered using only the lower tank in normal times, and when the pool water filtration function is increased or a new filter is used. In this case, you can use the pool water from both the upper tank and the lower tank by storing a new filter medium or filter in the upper tank and then connecting the drain pipe of the upper tank to the water supply pipe of the lower tank. can be filtered. Therefore, the ability to purify pool water can be increased as needed, and the filter medium or filter in one tank can be replaced while the other tank is in use, increasing work efficiency. It has the effect of being measured.

In addition, since the lower tank and the upper tank are arranged so that they can be divided vertically, the floor area occupied by the filtration device itself is extremely small due to the fact that they are consolidated on a flat surface, which is advantageous in terms of equipment layout. .

Furthermore, it is possible to filter pool water in stages or to install a new pool filtration system at regular intervals, making it especially economical since there is no need to dismantle existing equipment when adopting a new filtration system. It has great advantages in terms of aspects, and can contribute to streamlining the management of sports clubs.
