BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing foreign matter in a water conduit such as agricultural water, industrial water, and water supply.

[0002]

2. Description of the Related Art A large amount of foreign matter is mixed in a pipeline through which raw water flows, such as a water pipe for agricultural water, industrial water, and water supply, and the foreign matter may bite into a seat portion of a valve to cause malfunction. . In particular, since the discharge valve at the end of the conduit adjusts the discharge flow rate and has an intermediate opening degree (restricted state), foreign substances are more easily bitten. If a strainer is inserted to remove the foreign matter, the foreign matter can be removed.

Further, in order to remove foreign matter in the middle of a pipe,
Drainage equipment as shown in FIG. 4 is provided. In this drainage facility, a drainage pipe 2 is inserted into the bottom of a concrete drainage chamber 1, a valve 3 is attached to the tip of the drainage pipe 2, and a discharge pipe 4 is provided at the top of the drainage chamber 1. The drainage flowing into the drainage chamber 1 from the drainage pipe 2 flows out from the discharge pipe 4. Drainage temporarily stops in the drainage chamber 1, foreign matter heavier than water accumulates at the bottom of the drainage chamber 1, and foreign matter in the drainage is removed.

[0004]

When the strainer is inserted into the water conduit to remove the foreign matter as in the former case, the foreign matter can be removed, but the accumulated foreign matter is removed outside the pipeline. However, there is a problem that it takes time.
Further, in the case of the latter drainage equipment, the efficiency of removing foreign substances in the drainage is not very good.

The present invention has been made in order to solve the above-mentioned problems, and it is easy to remove foreign matter in a pipeline.
It is another object of the present invention to provide an apparatus for removing foreign matter in a pipeline which can be performed quickly.

[0006]

According to the present invention, there is provided an apparatus for removing foreign matter in a pipeline, comprising a main body for removing foreign matter, an inflow portion into which a fluid flows, and an end portion which is disposed on an extension of the inflow portion and which is opened and closed by a drain valve. And a discharge section that is disposed between the inflow section and the storage section and that discharges a fluid. One reducer is provided, a second reducer narrowed in the direction of the inflow portion is provided on the stagnation portion side, and a small hole is formed in the second reducer for filtering foreign matter.

[0007]

In the apparatus for removing foreign matter in a pipe constructed as described above, the fluid flows into the inflow portion, is squeezed by the first reducer, and is discharged to the second reducer. The fluid and foreign matter ride on the flow and are further inside the second reducer. Is pushed into the stagnation area. The fluid having nowhere to go is back-flowed, passes through the small hole of the second reducer, and is discharged through the discharge section. The foreign matter is filtered by the small holes of the second reducer, stays in the staying portion for a certain period, and is discharged from the staying portion. In this way, foreign matter in the pipeline can be easily and quickly removed.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a used state of the apparatus for removing foreign matter in a pipe. In this figure, reference numeral 10 denotes a concrete water tank, and a foreign matter removing apparatus 11 in a pipe is provided at the bottom of the water tank 10. .

The foreign matter removing device body 12 of this embodiment uses a T-shaped tube, and has an inflow portion 13 into which water flows, and an inflow portion 13.
Staying part 14 which is arranged on the extension of
And the discharge section 15 which intersects the storage section 14 at right angles. However, the foreign matter removing device main body 12 does not need to be exactly T-shaped, and may be slightly deformed.

[0010] The inflow portion 13 of the T-shaped pipe is connected to a water pipe 17 through a control valve 16, a drain valve 18 is attached to an end of the stagnation portion 14, and a discharge valve is connected to an end of the discharge portion 15. Valve 19 is mounted. These valves 18,19 are controlled by controllers 20,21. Note that the discharge valve 19 may be any of a control valve, a water level control valve, and a float valve.

With the discharge section 19 as a boundary, the inflow section 13 in the T-shaped pipe
The first reducer 22 is arranged on the side, and the second reducer 22 is
Reducer 23 is provided. The first reducer 22 is narrower in the direction of the stagnant portion 14 and the second reducer 23 is narrower in the direction of the inflow portion 13 and connected to each other. Since the second reducer 23 is made of a punching board, many small holes 24 are opened. In addition, this small hole
The size of 24 is selected according to the state of the foreign matter and the size of the foreign matter to be removed.

Next, the operation of the above configuration will be described. Water conduit
The water in 17 flows into the inflow section 13 and is squeezed by the first reducer 22, and has the highest flow velocity at the tip of the first reducer 22,
Foreign substances are released to the second reducer 23 along the flow. The foreign matter is inerted by the second reducer according to the flow velocity.
It is pushed into the staying part 14 further inside of 23.

The water that has been squeezed by the first reducer 22 and has a high flow velocity pushes the foreign matter into the stagnation portion 14 and, at the same time, has no place to go and flows backward, and the small hole 24 and the discharge portion 15 of the second reducer 23
Through the discharge valve 19 into the water tank.

The removal of foreign matter staying in the staying portion 14 for a certain period can be easily performed by setting the control valve 16 to a small opening, closing the discharge valve 19 and fully opening the drain valve 18. Next, another embodiment of the apparatus for removing foreign matter in a pipeline will be described.

FIG. 2 is a plan view when the foreign matter removing device in a pipeline is used for drainage equipment, and FIG. 3 is a longitudinal sectional view when the foreign matter removing device in a pipeline is used for drainage equipment. Since the foreign matter removing device 11 in a pipeline has the same configuration as that of the above-described embodiment, details of the configuration are omitted with the same reference numerals.

In the drainage system of this embodiment, a stagnant portion 14 is inserted into the bottom of a concrete drainage chamber 30, and a discharge pipe 31 is provided above the drainage chamber 30. In the drainage device 11 for removing foreign matter in the pipe of the drainage system, the wastewater in the drainage pipe 32 enters the inflow portion 13 and is squeezed by the first reducer 22 as in the second embodiment.
Released to reducer 23. The drainage and foreign matter are pushed into the stagnation portion 14 further inside the second reducer 23 along with the flow, but flow backward, pass through the small holes 24 of the second reducer 23, pass through the discharge portion 15, and are discharged from the discharge valve 19. You.

The foreign matter staying in the staying portion 14 for a certain period of time makes the control valve 16 a small opening, the discharge valve 19 is fully closed, and the drain valve 18
Is fully opened, and is discharged from the retaining section 14 to the drainage chamber 30. Stagnation section
The drainage flowing into the drainage chamber 30 from 14 temporarily stops in the drainage chamber 30, foreign matter heavier than water accumulates at the bottom of the drainage chamber 30, and the wastewater from which the foreign matter has been removed flows out of the discharge pipe 31.

In the drainage system of this embodiment, the foreign matter in the wastewater is quickly removed by the foreign matter removing device 11 in the pipeline, so that the drainage treatment capacity is much larger than that of the conventional drainage system.

[0019]

As described above, according to the present invention, the above configuration makes it possible to easily and quickly remove foreign matter in a pipeline. Therefore, there is no inconvenience that foreign matter bites into the valve seat of the discharge valve at the end of the pipeline.
