Abstract
Description
本発明は、金属表面をブラスト研磨する砂をキャプを設けた上部投入口より密閉タンク内に入れ上部より空気加圧して密閉タンク下部よりパイプで砂を混合器に圧送し高圧空気と砂を混合器の混合室で混合して混合器の先端に接続したノズルより安定的に噴出ブラストするものである。 In the present invention, sand for blasting a metal surface is put into a sealed tank from an upper charging port provided with a cap, air is pressurized from the upper part, and the sand is pumped from a lower part of the sealed tank to a mixer to mix high-pressure air and sand. The mixture is mixed in the mixing chamber of the mixer and ejected and blasted stably from the nozzle connected to the tip of the mixer.
従来サンドブラストはタンクに砂を入れ高圧空気を混合器のノズルから噴出して負圧を混合室に発生させ負圧の力でタンク下部からパイプで砂を導き高圧空気と混合して吐出ノズルよりブラストする方法が取られている。 In conventional sandblasting, sand is put in a tank and high pressure air is ejected from the nozzle of the mixer to generate negative pressure in the mixing chamber. The way to do is taken.
これには次のような欠点があった。
(イ)ブラストする空気の圧力が低かったり吐出ノズルの口径を小さくすると混合室の負圧が弱くなる為にタンクから混合器えの砂の導きが出来なくなりブラストが出来なくなる。
本発明はこれらの欠点を解決するためになされたものである。This has the following drawbacks.
(B) If the pressure of the air to be blasted is low or the diameter of the discharge nozzle is reduced, the negative pressure in the mixing chamber will be weakened, so that the sand of the mixer can not be guided from the tank, and blasting will not be possible.
The present invention has been made to solve these drawbacks.
高圧空気圧源から砂のブラスト圧力を調整する減圧弁にパイプで接続する。減圧弁からパイプでフートスィチで電源をON,OFFする電磁弁に接続する。電磁弁からでたパイプは分岐し密閉タンクを加圧する減圧弁に又は空気量を調整するニードルバルブに接続する。減圧弁又はニードルバルブから出たパイプは密閉タンク上部に接続する。密閉タンクの上部にキャプを設けた砂投入口を接続する。密閉タンク下部にパイプを接続しパイプを混合器の混合室に接続する。電磁弁から出て分岐した別のパイプを混合器の混合室に接続する。混合器の先端に砂が混合された高圧空気が噴出されるノズルが接続されたサンドブラスト装置。 A pipe is connected to a pressure reducing valve that adjusts the sand blast pressure from a high pressure air pressure source. Connect from the pressure reducing valve to the solenoid valve that turns the power on and off with a foot switch. The pipe from the solenoid valve is branched and connected to a pressure reducing valve that pressurizes the sealed tank or a needle valve that adjusts the amount of air. The pipe from the pressure reducing valve or needle valve is connected to the upper part of the closed tank. Connect a sand inlet with a cap at the top of the closed tank. Connect a pipe to the bottom of the closed tank and connect the pipe to the mixing chamber of the mixer. Connect another pipe branched from the solenoid valve to the mixing chamber of the mixer. A sandblasting device in which a high-pressure air in which sand is mixed is jetted to the tip of the mixer.
密閉タンク上部を加圧することにより加圧空気が砂の隙間を抜け下部パイプから混合器の混合室えと流れる為砂が混合器の混合室に圧送される。効率よく混合室で加圧空気と砂が混合して吐出ノズルより砂を安定的に高圧で勢いよくブラストすることが出来る。また加圧空気を調整する減圧弁又は空気量を調整するニードルバルブを設けたことによりブラストする砂の量を調整することが出来るようになった。 By pressurizing the upper part of the closed tank, the pressurized air passes through the gap between the sand and flows from the lower pipe to the mixing chamber of the mixer, so that the sand is pumped to the mixing chamber of the mixer. The pressurized air and sand can be mixed efficiently in the mixing chamber, and the sand can be blasted vigorously at a high pressure from the discharge nozzle. In addition, the amount of sand to be blasted can be adjusted by providing a pressure reducing valve for adjusting pressurized air or a needle valve for adjusting the amount of air.
以下、本発明の実施の形態について説明する。
(イ)高圧空気圧源(1)から出た高圧空気はパイプ(2)でブラスト圧力を調整する減圧弁(3)に接続する。
(ロ)減圧弁(3)で約0.6MPa減圧されフートスィチ(4)でON,OFFされる電磁弁(5)にパイプ(6)で接続する。
(ハ)電磁弁(5)を出たパイプ(7)は2方行に分岐する。
(ニ)分岐されたパイプ(7)はタンク加圧を調整する減圧弁(8)に接続する。
(ホ)減圧弁(8)を出たパイプ(9)を密閉タンク(10)の上部に接続する。
(ヘ)密閉タンク(10)にキャプ(11)を設けた砂投入口(12)接続する。
(ト)密閉タンク(10)の下部に接続されたパイプ(13)は砂と高圧空気を混合する混合器(14)の混合室(15)に接続する。
(チ)電磁弁(5)を出て分岐されたパイプ(16)は混合器(14)の混合室(15)に接続する。
(リ)混合器(14)の先端に砂が混合された高圧空気をブラストする吐出ノズル(17)を接続する。

(ヲ)(19)は電磁弁を働かす電源である。
(ヤ)(20)は密閉タンクに送る空気を調整するニードルバルブである。
本発明は以上のような構成でこれを使用するときは、混合器(14)を持ち吐出ノズル(17)をブラスト物に向ける。フートスィチ(4)を足で踏み電磁弁(5)を働かすと高圧空気圧源(1)からパイプ(2)、減圧弁(3)、電磁弁(5)、パイプ(16)、混合器(14)の混合室(15)と高圧空気が流れ吐出ノズル(17)から高圧空気が出てくる。電磁弁(5)より分岐されたパイプ(7)を高圧空気は通り、減圧弁(8)で約0.3MPaに減圧され上部より密閉タンク(10)の上部に注入する。注入された加圧空気は砂(18)の隙間を抜け密閉タンク(10)の下部に接続されたパイプ(13)を通り混合器(14)の混合室(15)に流れる為密閉タンク(10)の砂(18)は混合器(14)の混合室(15)に圧送される。高圧空気と混合された砂(18)は混合室の先端に接続された吐出ノズル(17)より勢いよく噴出され能率良く金属の表面等を砂でブラストできる。減圧弁(3)で砂が混合された高圧空気のノズルから噴出するブラスト圧力を調整することができる。減圧弁(8)で密閉タンク(10)に加圧する空気圧を調整することにより砂(18)のブラスト量を調整できる。Embodiments of the present invention will be described below.
