Compressed-air-operative complex vacuum cleaner

Abstract

Provided is a compressed-air-operative complex vacuum cleaner. The vacuum cleaner includes a storage tank for storing each variety of foreign materials; a lid positioned at a bottom of the storage tank, and being of an open / close structure; air cylinders provided at both sides of the lid, and fixed to the lid at ends of rods thereof; an ejector provided at an upper part of the storage tank; a compressed-air hose installed at the ejector, and supplying an external compressed air under the control of a control system; and a unit provided at the control system, and detecting contents provided within the storage tank.

Description

technical field [0001] The present invention relates to a vacuum cleaner, in particular to a compressed air operated vacuum cleaner which discharges various foreign matter from a storage box immediately. Background technique [0002] Traditional vacuum cleaners in the prior art are structured to drive a fan connected to the drive motor shaft placed in the sealed box of the electric cleaner, thereby reducing the internal pressure of the box to a lower pressure than the outside , while using the reduced internal pressure of the tank to filter the waste sucked in from the outside through the filter set in the tank. [0003] However, conventional vacuum cleaners are not sufficiently commercialized because they frequently break down and generate a lot of noise when used for a long period of time. In rainy weather, it is likely to cause electric shock when used as dewatering of shipbuilding blocks (parts of the hull) stacked at the shipyard, and the failure rate is high at high t...

Problems solved by technology

[0005] However, the conventional vacuum cleaner must stop the cleaning operation and tilt the storage box at an angle of 90° or more to discharge the collected foreign matter from the storage box, because a discharge member for discharging various foreign substances is provided at the upper part of the storage box

Therefore, the disadvantage of the conventional vacuum cleaner is that, due to the low discharge speed, the discharge process brings troubles to workers and delays the cleaning work, and various foreign objects cannot be completely discharged from the storage box.
