DESCRIPTION:
BRIEF SUMMARY
This invention relates to an apparatus for the recovery and storage of waste. In particular it relates to the recovery of hazardous waste such as hospital waste. Another application comprises the provision of a recovery and storage apparatus intended to be used as a water closet.
BACKGROUND AND OBJECTS OF THE INVENTION
The recovery and storage of waste, particularly hazardous waste, such as hospital waste, is carried out most often in an empirical manner using waste cans which, because of the need to be emptied and cleaned regularly, comprise a not-insignificant source of danger.
Further, and especially in the aeronautical field, the recovery and storage of waste which comprises human excrement poses serious problems of storage, giving rise at the present time to numerous research efforts seeking to solve these problems by means of drying by microwaves . . .
The present invention seeks to overcome these disadvantages and has as its principal object to provide an apparatus solving all of the above mentioned problems inherent in the recovery and storage of waste.
Another object of the invention is to provide an apparatus conceived to be able to operate in an autonomous manner.
Another object of the invention is to provide an apparatus permitting assurance of the treatment of waste, particularly in water closet applications.
DESCRIPTION OF THE INVENTION
To this end, the invention provides a waste recovery apparatus comprising: invaginating into the interior of said receptacle through the opening, said sheath having a cross-section less than that of the receptacle and being able to expand radially, opening, transverse with respect to the case, said obstacle being arranged to be positioned on the path of said sheath in such a manner as to incurve the path thereof, downstream of the direction changing obstacle, for: upstream of said carrying away means in such a manner as to cause a closing of the sheath upon contact with the direction changing obstacle, predetermined distance, in such a manner as to cause a new portion of the sheath to enter the receptacle, means.
Because of its conception, such a device constitutes a "mechanical siphon" which permits "downstreaming" and immediately isolating waste discarded in the receptacle.
In effect, the sheath is constantly maintained under tension because of its radial elasticity and the conception of the carrying away means, is closed at right angles to the direction changing obstacle which constitutes the barrier beyond which the waste is isolated.
In addition, the portion of the sheath situated at the point of the opening of the receptacle and thus able to be placed in contact with a source of contamination, is renewed with each evacuation operation.
According to another characteristic of the invention, the receptacle has a tubular cross-section comprising an increasing cross-section, widening in the direction of the inlet opening.
This conical shape for the inlet of the receptacle permits assuring a complete radial unfolding of the sheath regardless of the manner that this sheath has been arranged around the receptacle.
Furthermore, according to a preferred embodiment, this apparatus advantageously comprises: obstacle and the sheath carrying away means, and arranged so that the sheath passes to the interior of the reel, adapted to be unrolled around the first sheath, in such a manner as to encase the first sheath and to be drawn away therewith by the means for carrying away the sheath.
This encasing of the first sheath inside a sealed sheath represents a supplemental bacteriological barrier.
In addition, according to another characteristic of the invention, the apparatus comprises a pump adapted to be controlled by actuating means and provided with an aspiration inlet connected to a reservoir containing an antiseptic product, and having a discharge outlet connected to an injector arranged in the receptacle.
The vaporization of an antiseptic product comprises an active disinfection which assures a first bacteriological barrier and especially offers the possibilit
