Hose reel and jet cleaning machine

摘要

A tank cleaning machine which comprises a nozzle manifold having one or more nozzles, that can be fed into and retracted from a tank while rotating or oscillating while cleaning fluid is supplied from a hose so that jet cleaning streams are directed to only those areas inside the tank that require cleaning. A very important feature of this device is to be able to clean very long horizontal or high vertical tanks and have the nozzles move along the tank greatly reducing the distance that the jet cleaning streams must travel after leaving the nozzles resulting in greater impact scrubbing action and reducing the breaking up of the stream to give very high efficiency. The travel feature of the nozzle manifold also permits the addition of a mechanical scrubber, or scraper with a trip arm to allow removal of sludge as the manifold is removed from the tank. Several variations of the manifold track can be made, one is telescoping it for easy removal so that the entire machine can be moved from one tank to another if desired. The unique hose reel features allow a compact design and permits automatic programming to the necessary areas only with independent automatic operation of the rotation and travel features.
