Apparatus for cleaning an air pump silencer

U.S. Patent Number: 5678581

Abstract: A cleaning apparatus for cleaning an air pump silencer is disclosed. The cleaning apparatus comprises a closed housing. In the closed housing, at least one rotary part, each including a fixing plate and a support base for fixing the silencer is provided. Water from a water tank is injected into the silencer by first and second pipe sets. The first pipe set includes a straight pipe and a bent pipe mounted on the fixing plate. The second pipe set includes a straight pipe and a bent pipe mounted on the support base. During cleaning, these pipes enter the silencer and inject water to clean the inner walls of the silencer. A driving portion including a motor for driving the rotary parts is provided in the closed housing and is driven by a control circuit. When the rotary parts rotate, all the inner walls of the silencer can be completely cleaned by the pipes. Wash water is collected in an acid tank in the lower portion of the closed housing to isolate hazardous materials cleaned from the silencer.
