Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, a cold / hot water machine,
The present invention relates to a cooling tower that circulates and supplies cooling water used in heat exchangers and the like in various processes.

[0002]

2. Description of the Related Art Usually, a cooling tower is installed on the roof of a building. The water that circulates after a long period of operation is concentrated, and the equipment such as the refrigerator has an operational failure due to the adhesion of scale, the temperature rise of water, the dissolved oxygen, and the corrosion factors of the water such as the corrosion of the equipment and piping, Microorganisms, dust in the air,
This causes problems such as slime mixed with soil and sand, clogging of pipes with sludge generated from water stains, and generation of pathogenic bacteria. Therefore, inject the required amount of chemicals into the cooling tower,
Prevents the generation of scale, corrosion, slime and sludge,
In addition, it is necessary to carry out sterilization and stable operation.

[0003]

Conventionally, a chemical liquid tank for storing a chemical liquid is a vertically long vertical type, and a chemical liquid tank and a pump for injecting the chemical liquid into a cooling tower are individually installed on the rooftop separately from the cooling tower. are doing. Therefore, it is necessary to fix and support the chemical liquid tank, the pump, and the cooling tower individually on the rooftop, and they must be connected by piping.
It is very troublesome to install. Also, these rooftop cooling towers,
A large space is occupied by the chemical tank and pump,
There is little room for other uses.

[0004]

The present invention was developed in order to solve the above-mentioned problems, and a cooling tower main body is installed on a water tank having downward legs, a chemical liquid tank for water treatment, and A pump for supplying the chemical liquid in the tank to the cooling tower main body is installed on the pedestal, and is stored in the space below the water tank held by the legs. In this case, the chemical solution tank is a flat rectangular parallelepiped having a long side and a short side, one corner along one short side of the chemical solution supply port, and another corner along the short side at a right angle. Providing a cut recess,
A tank with a pump installed on the recess is installed on a stand,
It is stored in the space under the aquarium.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In each of the illustrated embodiments, 10 is a cooling tower body, 11 is a plurality of downward legs 12, and is a water tank on which the cooling tower body is installed. The length of the downward leg 12 of the water tank is usually about 50 cm. Reference numeral 13 is a chemical liquid tank, and when it is a flat type with a capacity of 100 vertical to store the chemical liquid for several days, as shown in the figure, the long side is about 1 m and the short side is about 50 c.
It can be a flat rectangular parallelepiped having a height of m and a height of about 30 cm. Further, the replenishing port for the chemical liquid which is opened and closed by the cap 14 is provided at one corner 15a along one short side 13a of the tank. Further, another corner 15b along the short side 13a is provided with a right-angled corner-cutting recess 16 and a pump 17 for liquid delivery is installed therein.

Then, the chemical liquid tank 13 is placed on a rectangular frame 18 of almost the same size. This pedestal may be a plate-like one as shown in FIG. 3 or a frame-like one as shown in FIG. 5 as long as the chemical liquid tank can be stably installed. The pedestal is provided with two long sides of the tank and a standing wall 19 along a short side 13b opposite to the short side 13a having a corner opening recessed portion 16 in which a supply port and a pump are installed. It prevents the chemical solution tank from swelling while it is in motion, and also prevents it from being moved by the wind when the chemical solution in the chemical solution tank becomes low. Further, as shown in FIG. 4, the chemical liquid tank 13 may be fixed to the pedestal 18 by using a fixing means such as a fixing belt 21. In this way, the chemical solution tank in which the pump is installed in the corner cutting recess is placed on the pedestal, and is stored in the space 20 below the water tank held by the legs 12. In this case, as shown in FIG. 2, the short side 1 of the tank
It is preferable to slightly project the 3a side out of the space 20. This is because by doing so, the cap 14 can be opened to easily supply the chemical liquid to the supply port, and the maintenance of the pump can be facilitated.

If necessary, the legs 12 may be connected to the pedestal 18 or the standing wall 19 with bolts and nuts.

[0008]

As is apparent from the above, according to the present invention, since the chemical liquid tank and the pump are stored in the space 20 under the water tank held by the legs 12, it is possible to effectively use a narrow space such as a rooftop. it can. Further, since the cooling tower main body, the chemical solution tank, and the pump are close to each other, connection by piping or the like is facilitated, and the construction period can be shortened and cost can be reduced.
