SUCTION DEVICE AND SUCTION VEHICLE INCLUDING THE SAME
PROBLEM TO BE SOLVED: To provide a suction device which can inhibit occurrence of noise even when a safety valve is operated during compression operation of a suction pump, and to provide a suction vehicle including the suction device.SOLUTION: A suction device 4 suctions and recovers a recovery object such as waste water and sludge to the tank 3 and includes: a suction pump 5 for decompressing or compressing the tank 3; an external communication pipe 10 for discharging air to the outside or suctioning air from the outside; an oil receiver 11 provided at a communication port communicating with the outside of the external communication pipe 10; and a safety valve 20 which opens when a pressure of an air pipeline 15 for supplying air to the tank 3 becomes higher than or equal to a setting pressure. A discharge port 20b which is opened when the safety valve 20 is opened is connected with the external communication pipe 10.SELECTED DRAWING: Figure 4
【課題】吸引ポンプの加圧動作時に安全弁が作動したとしても、騒音の発生を抑制することが可能な吸引装置およびこれを備えた吸引車を提供する。【解決手段】廃水や汚泥などの回収対象物をタンク３に吸引、回収する吸引装置４は、タンク３内を減圧または加圧するための吸引ポンプ５と、外部へエアーを排出または外部からエアーを吸引するための外部連通管１０と、外部連通管１０の外部との連通口に設けられたオイル受け１１と、タンク３内へエアーを供給するためのエアー配管１５の圧力が設定圧力以上になった場合に開弁する安全弁２０とを備え、安全弁２０の開弁時に開放される吐出ポート２０ｂが、外部連通管１０に接続されている。【選択図】図４
