Abstract

PROBLEM TO BE SOLVED: To dispense with a sedimentation tank so as to discharge water directly by filtering pumped water in a suction port. SOLUTION: By means of a bag-shaped water permeable filter 3, at least a part including a suction port 2 in a main body is covered in a submerged pump 1, or a suction port 2 at the tip of a suction hose is covered in a pumping out pump, and water is pumped up so as to be discharged while spring water is filtered by means of the water permeable filters 3 in each of these pumps. As fine sediment with a small particle diameter can be filtered off by means of the water permeable filter 3 arranged in the suction pod 2, the drain water can be discharged to the outside directly without arranging any sedimentation tank.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a submersible pump, a pumping pump, and a drainage method which are suitable for pumping out spring water mainly from excavation work in civil engineering and construction sites.

[0002]

2. Description of the Related Art In civil engineering and construction sites, when spring water is pumped out by a submersible pump or pumping pump, water containing a large amount of sediment cannot be discharged to the outside. The water is guided to the sedimentation tank to sediment the sediment, and the supernatant water is discharged to the outside. Sediment accumulated in the sedimentation tank is removed separately and treated as industrial waste.

[0003]

The conventional spring treatment described above requires a space for installing a settling tank in the site,
In addition, the sediment accumulated in the settling tank must be taken out and disposed of separately, resulting in a high cost. The present invention
By filtering the pumped water through the suction port, a sedimentation tank is not required and it can be directly discharged to the outside.

[0004]

According to the present invention, at least a portion of a main body including a suction port is covered with a bag-shaped water permeable filter, and a suction port at a tip of a suction hose has a bag-shaped water permeable filter. A pumping pump characterized by being covered with a filter, and a submersible pump or a suction hose in which a portion including a suction port is covered with a bag-shaped water permeable filter in a method of draining spring water associated with excavation work for civil engineering and construction. Is a pumping-out pump in which the suction port at the tip of is covered with a bag-shaped water permeable filter, and the spring water is sucked up and drained while being filtered by the water permeable filter.

The water permeable filter is formed by processing fibers such as non-woven fabric into a cloth, or forming a porous sheet such as an open-cell sponge into a bag shape. Generally, a cloth-like material obtained by processing fibers is superior in durability. The water-permeable filter shall be fixed by tying the mouth area to the body or hose with an appropriate fastener such as a rubber band.

[0006]

In the pump of the present invention, since the suction port is covered with the water permeable filter, the water is filtered by the water permeable filter and the water sucked by the pump is already purified.
Therefore, the water can be drained directly and no settling tank is required. Even if there is a request to further purify the water sucked up by the pump of the present invention and a sedimentation tank is provided, the amount of earth and sand accumulated in the sedimentation tank will be much smaller than before, and the removal work and disposal costs can be greatly reduced. .

Since the water-permeable filter has a bag shape,
It can be easily attached to the pump body or hose with an appropriate fastener such as a rubber band, and can be easily replaced when it becomes clogged. In addition, the water-permeable filter is a cloth or sheet processed into a bag shape, so it is flexible and can be used with pumps or suction ports of slightly different sizes or shapes, so there is no need to manufacture it for each model, There is a nature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments. FIG. 1 is an explanatory view of a submersible pump 1 of an embodiment of the present invention, FIG. 2 is an explanatory view of a submersible pump 10 of another embodiment, and FIG. 3 is a pumping pump 2 of the embodiment.
FIG. In addition, in each figure, the water permeable filter is partially cut away. Also, details such as the power cord are omitted.

The submersible pump 1 shown in FIG. 1 has a suction port 2 in the lower part of the main body and a drain port 5 in the upper part. A drain hose 6 is connected to the drain port 5 for sucking water from the suction port 2. The water is drained to the tip of the drain hose 6. The lower part of the body including the suction port of the submersible pump 1 is covered with a bag-shaped water permeable filter 3, and the mouth of the water permeable filter 3 is fixed to the body with a rubber band which is a fastener 4. The water permeable filter 3 is made of nylon non-woven fabric in a bag shape. As shown in FIG. 1, even if the submersible pump 1 is directly installed on the earth and sand 7, since the earth and sand are filtered by the water permeable filter 3 and the sucked water is filtered, the submersible pump 1 is directly connected to the drain hose 5. Wastewater can be discharged to the outside such as sewage.

The submersible pump 10 shown in FIG. 2 also has a suction port 11 at the bottom of the main body and a drain port 14 at the top.
A drain hose 15 is connected to the drain port 14, and the suction port 11
The water is sucked in from the drain and drained to the tip of the drain hose 15. The entire body including the suction port of the submersible pump 1 is covered with a bag-shaped water permeable filter 12, and the mouth of the water permeable filter 12 is fixed to a drain hose 15 with a rubber band which is a fastener 13. The water permeable filter 12 is formed by forming a water permeable open-cell sponge sheet into a bag shape. Even if the submersible pump 10 is directly installed on the earth and sand 16 as shown in FIG. 2, the earth and sand is filtered by the water permeable filter 12, and the drainage hose 15 can directly discharge the drainage to the outside such as sewage. it can.

The pumping pump 20 in FIG. 3 is installed outside, not underwater. The suction hose 21 and the drain hose 22 are connected to drain the water sucked from the suction hose tip to the drain hose tip. A strainer is connected to the tip of the suction hose, but this is a metal tube with many holes that can prevent the suction of relatively large gravel particles. It is not possible to prevent the ingestion of small sediments. The strainer, which is the suction port, is a bag-shaped water-permeable filter 24 made of nylon non-woven fabric.
The mouth of the water-permeable filter 24 is fixed to the suction hose 21 with a rubber band which is a fastener 25. FIG.
As shown in, even if the suction port is directly installed on the earth and sand 26, the earth and sand are filtered by the water permeable filter 24, and the drainage hose 22 can directly discharge the drainage to the outside such as sewage.

[0012]

EFFECTS OF THE INVENTION The pump of the present invention can filter even fine sand with a water-permeable filter provided at the suction port.
The wastewater can be discharged directly to the outside, and no settling tank is required. In addition, even if a sedimentation tank is provided due to a special request, the amount of earth and sand accumulated in the sedimentation tank will be much smaller than before, and removal work and disposal costs can be greatly reduced. The bag-shaped water permeable filter can be obtained at low cost and can be easily attached to the pump body or the hose with an appropriate fastener such as a rubber band. It is easy to replace when it becomes clogged. In the case of a submersible pump, covering the main body with a water permeable filter also has the effect of reducing noise.
