Description

【０００９】
かかる構成のものを図２に示すようなドレントラップ等のドレン貯溜部２０に対して圧縮空気を供給するエアーポンプ２２と、該貯溜部２０のドレン出口付近に接続されたドレントラップ等のバルブ２４と前記装置のドレン入口管１６とを接続することによりタンク３にドレンを排出するシステムが完成する。
以上述べた構成において本実施例にかかる排圧開放チャンバーは、上記のような条件で構成されている関係で縦長のものであり、バルブ２４が開放されることにより貯溜部２０から供給されるドレン及び圧縮空気は、ドレン入口管１６を介して筐体１０の天井部から筐体１０の底部に向けて噴出される。この時前記入口管１６が筐体１０の２０％の深さまで挿入されている関係から噴出された空気は排気穴１８に向けて短絡することなく噴出される。噴出された圧縮空気は、排気穴の総面積ｓが入口管１６の断面積に比較して１．５倍から２倍に形成してある関係から、噴出圧力は減殺された状態で筐体１０の底部又はドレンと衝突し上昇流に切り変わる。切り変わった空気は主に筐体の側壁に沿って上昇していき、一部は入口管１６から噴出される空気と接触してさらに勢いを互いに弱めあう。
その結果ドレン入口管１６から噴出された水滴は、圧縮空気の上昇流による影響が小さいので、自重で筐体底部に落下することとなる。
さらに筐体１０の下方に溜ったドレンは、側面下方にドレン出口１２が設けられている関係から緩やかにタンク１に向けてドレンだけが流出することとなる。

【効果】
以上述べたように本発明にかかる排圧開放チャンバーは、従来のように密度の高いメッシュ等を使用しないので、目詰りが起こりにくい。また縦長の筐体においてドレン入口管を所定の深さまで挿入して底部に向けて噴出するように構成しているための従来のようにメッシュの密度が粗いために空気と共に水滴まで外気に排出されることがない。
さらに、メッシュ等の細かな部品を使用することなく効率良くエアー抜きを行うことができるので、従来のものに比較してメインテナンス作業を軽減することができる。

[Industrial application fields]
The present invention is a system in which drain discharged from a device such as a compressed air dehumidifier is once collected in a tank, and when a certain amount is accumulated, the drain is supplied to the large tank by supplying compressed air into the tank. It is related with the improvement of the apparatus for venting air.
[0002]
[Prior art]
As shown in FIG. 3, as a method and a method for venting compressed air sent to a conventional tank together with a drain, a drain inlet 2 and a drain outlet 3 are provided on the side of the tank 1 covered with six faces, and a ceiling portion is provided. In the case where the air outlet 4 is provided, the air outlet provided with air venting means 5 such as a filter, a mesh, and a hole is provided for use.
[0003]
[Problems to be solved by the invention]
In such a device, when the density of the mesh or the like is increased, there is a problem that air is difficult to escape due to filtration resistance and it is difficult to release the air because foreign matter is easily clogged. There was a problem that the removal work required time.
When the density of the mesh or the like is lowered, there is an inconvenience that water droplets are ejected together with air although there is an advantage that the air is easily removed due to the small filtration resistance.
Accordingly, the present invention has been made in view of the drawbacks of the prior art, and provides a chamber for venting air that releases only air to the atmosphere without releasing water droplets ejected into the tank together with compressed air to the atmosphere. Objective.
[0004]
[Means for Solving the Problems]
That is, the present invention is provided with a bottomed cylindrical casing and a lower side of the casing in a system in which drain is supplied from a drain storage section such as a drain trap to a tank or the like at a predetermined amount using compressed air. Consists of a drain outlet, a drain inlet pipe provided in the ceiling part of the casing, and an exhaust hole provided in the ceiling part around the drain inlet pipe, and the volume of the drain is more than twice the amount of drainage to which the casing is fed And the cross-sectional area of the casing is configured to be at least four times the cross-sectional area of the drain inlet pipe, the total area of the exhaust holes is configured to be at least 18% of the cross-sectional area of the casing, and the drain inlet A drainage pressure release chamber for draining drainage, wherein the chamber is inserted to a depth of 20% or more of the depth of the casing of the tube.
[0005]
[Action]
In the exhaust pressure release chamber according to the present invention, the drain inlet of the tank and the drain outlet of the chamber are connected, and the water supply pipe from the drain reservoir such as a drain trap and the drain inlet pipe are connected.
In a drain storage section such as a drain trap, when a predetermined amount (for example, 600 cc) of drain has accumulated in the tank, the valve is opened, and 600 cc of drain together with compressed air is sent to the chamber.
The drained water is jetted toward the bottom of the casing together with the compressed air through the inlet pipe of the apparatus, and the drain tends to accumulate at the bottom of the casing. On the other hand, the compressed air ejected together with the drain is ejected toward the bottom of the housing in a state where the pressure is reduced because the cross-sectional area in the housing is formed wider than that of the inlet pipe, and collides with the bottom or drain. After that, it flows toward the exhaust hole of the casing ceiling. At this time, it collides with the drain or the like ejected from the drain inlet pipe and is released to the outside from the exhaust hole in a state where the mutual momentum is further reduced. Since the drain inlet pipe is inserted all the way toward the bottom of the casing, there is no short circuit from the drain inlet pipe to the exhaust hole.
[0006]
【Example】
In the following, the invention will be described in detail according to the illustrated embodiment.
In FIG. 1, reference numeral 10 denotes a cylindrical bottomed casing, which is composed of a vertically long casing having a height of about 500 to 1000 mm and a cross-sectional inner diameter of 50 mm or more with a water supply amount of 600 cc per time. A drain outlet 12 is provided at the lower side of the side.
Reference numeral 14 denotes a lid connected to the upper portion of the housing 10, and a hole for connecting the drain inlet pipe 16 is formed in the center, and a plurality of exhaust holes 18 are formed around the hole. The drain inlet pipe 16 is inserted to a depth of 20% or more from the lid body 14 of the housing 10 toward the bottom of the housing.
[0007]

Inner diameter of casing… R

Inside diameter of drain outlet ... r '

The exhaust pressure release chamber is created so as to satisfy the following conditions.
[0008]

[0009]
An air pump 22 for supplying compressed air to a drain reservoir 20 such as a drain trap as shown in FIG. 2 and a valve 24 such as a drain trap connected near the drain outlet of the reservoir 20 as shown in FIG. And a drain inlet pipe 16 of the apparatus are connected to complete a system for discharging the drain to the tank 3.
In the configuration described above, the exhaust pressure release chamber according to the present embodiment is vertically long because it is configured under the above conditions, and the drain supplied from the reservoir 20 when the valve 24 is opened. The compressed air is ejected from the ceiling of the casing 10 toward the bottom of the casing 10 through the drain inlet pipe 16. At this time, the air ejected from the relationship in which the inlet pipe 16 is inserted to a depth of 20% of the housing 10 is ejected toward the exhaust hole 18 without short-circuiting. The jetted compressed air has a relationship in which the total area s of the exhaust holes is formed to be 1.5 to 2 times as large as the cross-sectional area of the inlet pipe 16. It collides with the bottom of the water or drain and switches to upward flow. The changed air rises mainly along the side wall of the casing, and some of the air comes into contact with the air ejected from the inlet pipe 16 and further weakens the momentum.
As a result, since the water droplets ejected from the drain inlet pipe 16 are less affected by the upward flow of the compressed air, they fall to the bottom of the casing under their own weight.
Further, the drain that has accumulated below the housing 10 is gently drained toward the tank 1 due to the relationship that the drain outlet 12 is provided below the side surface.
[0010]
【effect】
As described above, the exhaust pressure release chamber according to the present invention does not use a high-density mesh or the like as in the prior art, so clogging hardly occurs. In addition, since the drain inlet pipe is inserted to a predetermined depth in a vertically long casing and is ejected toward the bottom, the mesh density is low as in the conventional case, so that water and water droplets are discharged to the outside air. There is nothing to do.
Furthermore, since air can be vented efficiently without using fine parts such as a mesh, maintenance work can be reduced as compared with the conventional one.
