Description

  The present invention relates to an agitation device used for agitating a liquid flowing in a flow path. In particular, the present invention relates to a purified water system that takes in water from a water source such as a pond and purifies the water. The present invention relates to a stirrer for agitating purified water when discharged into the water, and a water purification system using the agitator.

  As a conventional water purification system, a water purification system that performs filtration and magnetization on water taken from a water source is often used. By filtering the water taken from the water source, impurities and foreign substances are removed, and by applying a magnetic field to the water taken from the water source, metals such as iron and nickel contained in the water are removed, and water molecules Is activated, oxygen is taken up into water, and an environment in which aerobic microorganisms propagate is generated. When aerobic microorganisms propagate, biological self-cleaning works to improve the quality of the water source.

  In addition, simply returning the magnetized water to the water source does not sufficiently supply oxygen to the water. Therefore, in order to supply sufficient air to the magnetized water, There has been proposed a water purifier in which an intake pipe for introducing air into purified water to be discharged is connected to a discharge pipe for discharging water into a water source (see, for example, Patent Document 1). In this water purifier, the distal end portion of the discharge pipe is formed in a small diameter region with a narrowed diameter, and suction force is generated in the intake pipe by facing one end of the intake pipe in the small diameter region. With this suction force, air is taken in from the other end of the intake pipe, and air is introduced into the discharge pipe.

  In the water purification apparatus configured as described above, air introduced into the purified water flowing through the discharge pipe is mixed as bubbles and oxygen is introduced into the water. There is a problem that air does not mix well, the amount of oxygen taken into water is reduced, and the purification function by aeration is not fully exhibited.

  In addition, there is a method to stir the water with a submersible pump by introducing a stirrer into the water source. However, since a machine that requires a power source is required separately from the water purifier, the equipment becomes large and expensive. There is a problem of being bulky.

  The present invention has been made paying attention to the above-mentioned problems, and is a stirrer capable of sufficiently stirring and mixing bubbles and the like in purified water after magnetization treatment by a simple method that does not require a power source and the stirrer. It aims at providing the water purification system using an apparatus.

Each water passage hole of each plate member is displaced so as not to overlap with each water hole of the upstream plate member.

  According to the present invention, the liquid fed into the stirring device flows through the flow path in the cylinder, and the liquid is stirred by the stirring member provided in the middle of the flow path. The liquid flows through a plurality of water holes provided on the entire surface of the plurality of plate members constituting the stirring member, but each water hole is displaced so as not to overlap with each water hole of the upstream plate material. Therefore, every time the liquid passes through the misaligned water passage hole, the flow of the liquid is naturally changed, and thereby the liquid is stirred.

  In a preferred embodiment of the present invention, all the plate members are grouped into a plurality of sheets, and are displaced so that each water hole does not overlap with each water hole of the upstream group plate material. ing.

  According to this embodiment, when the liquid passes through the water holes of each plate member in the same group, the positions of the water holes are aligned, so that the flow proceeds straight without being changed. When the plate member of this group is reached, the water flow holes are displaced, so that the flow of the liquid is naturally changed, whereby the liquid is stirred.

  In a further preferred embodiment of the present invention, all the plate members are constituted by plate members having the same shape and position of the water passage holes, and each plate member is rotated by a predetermined angle with respect to the upstream plate member. Therefore, each water passage hole is displaced so as not to overlap with each water passage hole of the upstream plate.

  According to this embodiment, since the shape and position of the water passage holes of all the plate materials are configured in the same manner, it suffices to manufacture all the plate materials by the same processing method, and the production of the plate materials is troublesome. Therefore, parts management is also easy.

In another preferred embodiment of the present invention, the water passage hole has a different shape for each predetermined group of plate members.
According to this embodiment, every time the liquid reaches a group having a different shape of the water passage hole, the flow of the liquid is naturally changed, so that the liquid stirring effect can be enhanced.

An intake pipe for introducing air into the water is disposed, and the stirring device according to any one of the above embodiments is connected to the discharge port of the discharge pipe.

  In the above-described water purification system, the air taken in by the intake pipe is introduced into the purified water that has been subjected to the purification process such as the magnetization process flowing through the discharge pipe as bubbles. When the purified water flows through the stirring device, the purified water is stirred by the stirring member. As a result, air is sufficiently stirred and mixed into the purified water, so that the amount of oxygen taken into the water is increased, and the purification function by aeration is further promoted.

According to the present invention, the flow of the liquid is naturally changed and the liquid is agitated only by shifting the position of the water passage holes of the plate members so as not to overlap the water passage holes of the upstream plate member. Therefore, bubbles and the like can be stirred and mixed in water without using power.
