DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for collecting floating residue or sediment of a sand basin in a sewer.

[0002]

2. Description of the Related Art Conventionally, scum contained in sewage floats in a sedimentation bag or sedimentation basin, and gravely sediment sinks to the bottom as sand.

[0003] In order to suck and discharge the residue, the scraper provided on the stand on the sand basin rakes and discharges it to the discharge gutter. Was.

When the residue floating on the water surface is suctioned by a rotary or piston pump, the air on the water surface is sucked and released to the atmosphere, so that it is difficult to suck water thereafter. Of course, it was difficult to suck up the residue.

Further, in the case of the rotary pump, overload of the pump is stopped due to solid matter (for example, a so-called 100 yen lighter or the like) scattered in the pump. There is a problem that the equipment is enlarged to solve this problem.

[0006]

DISCLOSURE OF THE INVENTION The present invention provides a simple facility that can safely and reliably return only the water to the original sedimentation basin by floating the sedimentation basin of the sewer, collecting the residue and the sediment and collecting it with a filter. The purpose is to gain.

[0007]

To achieve the above object, the present invention provides a snake pump outside a sand basin, and connects a closed supply section of the pump and a bottom of a strainer closed tank by piping. A suction hose is connected to the upper end of the tank, and a sewer sediment or sediment sampling machine formed to suck the sediment or sediment of a sand basin from the opening at the tip of the hose. A sewer sediment or sediment sampling machine according to the first aspect of the present invention, wherein the sediment is fixed and a synthetic resin net bag is arranged inside the strainer, and sediment or sediment is collected in the bag. A sewer sediment or sediment sampling machine according to the first or second aspect of the present invention, wherein a strainer through which the sediment or the sediment is passed is provided in the opening so that the hose is not clogged. Connect Subsequently, the drainage hose or the sediment collection device according to any one of the first to third aspects of the present invention is connected to a discharge hose via a riser.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A machine base 13 is provided at a ground surface outside a sand basin 1 in a sewer, and a snake pump 2 and a motor unit 3 'shown in FIG.
The supply section 3 and the bottom of the strainer sealed tank 4 are connected by a pipe 5.

As shown in FIG. 2, the strainer sealed tank 4 is sealed by tightening an upper end sealing plate 4a on an upper end flange 4 "of a cylindrical sealing tank 4 'with a bolt 14, and at this time, the flange 4" and the upper end sealing plate 4a are sealed. Upper end edge flange 1 of stainless steel inverted truncated cone (bucket type) strainer 10
0 ′ and the upper edge of a synthetic resin net bag 11 (bucket shape) hanging in the strainer 10.

An upper short pipe 15 is provided on the upper end sealing plate 4a,
The hose 6 is connected to the hose 6 via an elbow 16, the lower end of the hose 6 is opened below the water surface 1 ′ of the sand basin 1 by a manual rod 17, and a suction guide expanding cylinder 7 ′ is provided in the opening 7. A mesh strainer 12 smaller than the inner diameter of the hose 6 is provided at the inlet of 7 '.

On the other hand, a hose 6 ′ hanging down toward the water surface 1 ′ of the sand basin 1 is directly connected to the discharge port 2 ′ of the snake pump 2, or a short upright pipe 18 is connected to the discharge port 2 ′ via an elbow 16. The hanging hose 6 ′ is connected to the upper end of the upright pipe 18 via an elbow 16 to fill the water in the upright pipe 18 into the snake pump 2, and to prevent the air from entering in reverse from the discharge port 2 ′. Blocking, rubber stator S and rotor R
And the start of the snake pump 2 is performed smoothly.

When the motor unit 3 'is operated to rotate the rotor R of the snake pump 2 to one side, the tank 4 enters the independent space e between the rotor R and the rubber stator S due to the interaction between the rotor R and the rubber stator S. The space e is swung from left to right in FIG. 3 to move and is discharged to the water surface 1 'via the hose 6'.

By the operation of the snake pump 2 as described above, the pressure of the supply section 3, the pipe 5, and the strainer sealed tank 4 is reduced, and the residue 8 or the bottom portion floating on the water surface 1 'via the hose 6 and the suction guide expanding cylinder 7'. Sand 9 of the strainer 1
2 into the cylindrical sealed tank 4 ', fill the synthetic resin mesh bag 11, fill the bag 11 with the stainless steel inverted truncated cone strainer 10, and the mesh or the mesh of the strainer 10 The filtered water is discharged from the through hole 10 ″ into the tank 4 ′, and further discharged from the pipe 5 through the supply unit 3 to the water surface 1 ′ by the snake pump 2.

The outer circumference of the mesh bag 11 is designated by the reverse truncated strainer 10 made of stainless steel.
Numeral 0 is supported by the support frame 10a and filtered and sucked by the bag 11 and the strainer 10. The residue 8 and the sediment 9 remain in the mesh bag 11, and after filling, stop the snake pump 2 and open the upper end sealing plate 4a. Then, the mesh bag 11 filled with the residue 8 or the sediment 9 is lifted by a crane and discharged out of the machine. The empty mesh bag 11 is inserted into the stainless steel strainer 10 and the upper edge is formed in the flange of the tank 4. 4 "and the upper end sealing plate 4a to return to the original state, and this is repeated.

The above strainer 1 made of stainless steel (iron)
The small solid matter passing through the water and passing through the pipe 5 and the supply unit 3 enters the space e of the snake pump 2 and turns, is discharged from the discharge port 2 ', falls to the water surface 1', and is fixed to the rubber stator. S and the stator S
There is no risk of damage.

[0016]

According to the present invention, as described above, the residue and the sediment are sucked together with the water by the snake pump, and the residue and the sediment being sucked and transferred in the closed tank are filtered on the way. Not only can it be recovered, but solids that pass through the strainer in the closed tank and get into the water can safely pass through the snake pump and can be safely and securely returned to the sand basin without damaging the pump There is an effect that simple equipment can be obtained.
