Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to an air exhaust silencer.

(Prior art) A known technique is to form an inflow chamber and an outflow chamber by providing a vertical partition plate inside a vertical cylindrical container, the lower end of which is connected to the bottom plate, and the upper end of which reaches a position below the horizontal partition plate. Then, an inflow tube is attached to the lower side of the inflow chamber,
An outflow tube is provided at the bottom of the outflow chamber, a small diameter concentric through hole is formed in the center of the horizontal partition plate, and a vertical automatic air venting device tube is provided in the center of the top plate of the cylindrical container. The vertical partition plates were flat.

(Problems to be Solved by the Invention) Therefore, there was a problem in that the air bubbles rising in the inflow chamber did not escape into the air chamber and flowed into the outflow chamber with excess force.

(Means for solving the problem) In order to prevent this, it is preferable to give a horizontal rotation to the flow of water in the inlet chamber. Therefore, the present invention has been devised by providing inside a vertical cylindrical container 1 a vertical vertical partition plate 10 whose lower end 11 is connected to the bottom plate 2 and whose upper end 12 reaches a position below the horizontal partition plate 5.
3 and an outflow chamber 14, an inflow pipe 15 is attached to the lower side of the inflow chamber 13, an outflow pipe 16 is provided to the lower side of the outflow chamber 14, and a small diameter pipe is installed in the center of the horizontal partition plate 5. A concentric through-hole 9 is formed in the cylindrical container 1.
A vertical automatic air venting device tube 8 is provided in the center of the ceiling plate 4, and the portion of the vertical partition plate 10 facing the inlet tube 15 has a mountain-shaped cross section. The body 17 is an air exhaust silencer.

One embodiment of the present invention will be explained with reference to the drawings.
2 is a vertical container, 2 is a horizontal bottom plate, 3 is a cylindrical part with the same diameter from beginning to end, 4 is a dome-shaped ceiling plate formed on the top of the cylindrical part 3, and 5 is a horizontal partition plate provided from the top of the inside. The upper part of the horizontal partition plate 5 is formed into an air chamber 6. At the center of the ceiling plate 4, a mounting tube 8 for an automatic air venting and silencer 7 is provided. The lower end of the mounting tube 8 is opened at the center of the air chamber 6. A through hole 9 with a diameter of about 1/2 is opened in the center of the horizontal partition plate 5. Reference numeral 10 denotes a vertical partition plate whose lower end 11 is connected to the bottom plate 2 and whose upper end 12 faces slightly below the through hole 9. By providing the vertical partition plate 10, the interior of the cylindrical portion 3 of the container 1 can be separated from one side. one is formed in the inflow chamber 13 and the other is formed in the outflow chamber 14. Inflow chamber 1
A horizontal inflow tube 15 is provided from the bottom of 3,
A horizontal outflow cylinder 16 is provided below the outflow chamber 14. The water flowing in from the inflow pipe 15 passes through the vertical partition plate 1
A mountain-like body 17 is formed on the surface of the vertical partition plate 10 facing the inflow tube 15, which collides with the water at a right angle to zero, but distributes the water to the left and right sides and causes it to swirl horizontally.

The mountain-shaped body 17 is provided over the entire length of the vertical partition plate 10 in the vertical direction. Therefore, both 18 and 19 become swirl chambers.

(effect) Next, we will discuss the effect.

The water flowing in from the inlet pipe 15 is distributed to the left and right sides by the mountain-shaped body 17, and turns into swirling currents in opposite directions in the swirl chambers 18 and 19, respectively, and rises. Therefore,
The separation of air bubbles is more active than that of the conventional one, and the separated air bubbles rise directly to the through hole 9.
The air bubbles enter into the air chamber 6 and are discharged from the automatic air vent silencing device 7 through the mounting tube 8, thereby preventing some of the air bubbles from flowing into the outflow chamber 14. Water containing air bubbles is removed from the upper end 12 of the vertical partition plate 10.
The air rises to a point where the air is evacuated and flows into the outflow chamber 14.
Since an outflow tube 16 is formed in the lower part of the outflow chamber 14, the evacuated water is discharged from the outflow tube 16.

(Effects) The present invention provides a vertical partition plate 10 whose lower end 11 is connected to the bottom plate 2 and whose upper end 12 reaches the lower position of the horizontal partition plate 5 inside the vertical cylindrical container 1 to form an inflow chamber 13. An outflow chamber 14 is formed, an inflow cylinder 15 is attached to the lower side of the inflow chamber 13, an outflow cylinder 16 is installed to the lower side of the outflow chamber 14, and a small diameter concentric pipe is installed in the center of the horizontal partition plate 5. In the case where a through hole 9 is formed and a vertical automatic air venting device cylinder 8 is provided in the center of the top plate 4 of the cylindrical container 1, the vertical partition plate 1
Since the air exhaust silencing device has a mountain-like body 17 having a mountain-shaped cross section formed on the portion facing the inflow tube 15 of the air vent, air bubbles will not flow out into the outflow chamber 14 as in conventionally known devices. It has the feature of being able to completely remove air without any problems.
