Abstract

<P>PROBLEM TO BE SOLVED: To solve problem of conventional suction ports wherein when settled sludge and slime at the bottom are sucked by vacuum, a hose is clogged therewith and suction is disabled, and a working efficiency is lowered. <P>SOLUTION: A suction force by vacuum and a force for lifting and transferring produced due to the difference between the specific gravity of a fluid flowing in the hose and the specific gravity of a fluid flow on the outside of the hose are applied to the hose. Consequently, the working efficiency is increased without stopping the suction during the operation. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、バキュームにより（沈殿汚泥・へどろ）などを引き抜き作業時に、ホース内で詰まらないように改良したものです。 The present invention has been improved to prevent clogging in the hose during vacuuming (sediment sludge, sludge) and the like.

従来は、（沈殿汚泥・へどろ）などをバキュームで吸い込み時、ホース内で詰まって吸い込みが出来なくなり、作業効率を落としていた。 In the past, when sucking (sediment sludge, sludge), etc. with a vacuum, it was clogged in the hose and could not be sucked in, reducing work efficiency.

バキュームで作業中に底にある（沈殿汚泥・へどろ）などを吸い込み時に、吸い込みが止まることや、ホース内で詰まることがよくある。これらを解決することを課題とする。 When working with vacuum (sediment sludge, sludge), etc., the suction often stops or clogs in the hose. The problem is to solve these problems.

Means to solve the problem

請求項１の発明は、［図１］のようにバキュームホースに、バキュームホース用エアーリフト式吸い込み口とエアーホースを装着して作業する。バキュームによる吸入力はエアーホースより空気を吸い込みエアー吸入管の中に入ってバキュームホース内に入る。バキュームホース内に入った空気は、ホース内液の比重を小さくすることにより、ホース外側の液体比重の差で揚送する力がバキュームの吸入力に加わる。 According to the first aspect of the present invention, as shown in FIG. 1, the vacuum hose is equipped with an air lift suction port for a vacuum hose and an air hose. The suction input by the vacuum sucks air from the air hose, enters the air suction pipe, and enters the vacuum hose. The air that has entered the vacuum hose reduces the specific gravity of the liquid in the hose, so that the force to be pumped by the difference in liquid specific gravity outside the hose is applied to the vacuum suction input.

The invention's effect

本発明は、バキューム作業中底にある（沈殿汚泥・へどろ）などを吸い込み時、ホース内で詰まって、吸い込みが出来なることがよくあり作業効率を落としていた。底の（沈殿汚泥・へどろ）などを吸い込み時でも、ホース内で詰まらないし、ホース内をスムーズに流れるようにした。 In the present invention, when suctioning (sediment sludge, sludge, etc.) at the bottom during vacuum work is sucked, it is often clogged in the hose and can be sucked in, which reduces work efficiency. Even if the bottom (sediment sludge / slot) is sucked in, it will not clog in the hose and flow smoothly through the hose.

The figure shows the air hose 4 fitted in the air suction pipe 2 of the air lift type suction port body 1 for the vacuum hose. When sludge is pulled out in the state of [FIG. 1], the air hose 4 works from the water surface. At the same time as the sludge is sucked by the suction input, air is also sucked from the air hose 4, and the specific gravity of the liquid in the hose is reduced by passing through the air suction pipe 2 through the air suction port 5 and entering the vacuum hose 3. As a result, a force to be lifted by the difference in liquid specific gravity outside the hose is added to the suction input.

本発明に係るバキュームホース用エアーリフト式吸い込み口は、工業的に量産する事が可能であるため、産業上の利用可能性を有する。 Since the air lift suction port for a vacuum hose according to the present invention can be industrially mass-produced, it has industrial applicability.
