Embodiment Construction

[0040] [40] Figures 1-3 present a schematic arrangement illustrating the concept of the present invention.

[0041] [41] Figure 1 shows a closed cavity 1 for cleaning operations, into which it has to be inserted. The device according to the invention comprises a pressure-relief device 2 connected to the chamber through a first opening, which in this embodiment is a pump, and a device for sudden pressure relief 3 connected to the enclosure through a second opening. Chamber 1, which in this embodiment is a valve-type release means, is connected to a reservoir containing a fluid 4, which in this embodiment is air at atmospheric pressure.

[0042] [42] For simplicity, the cavity is schematically represented as a rectangle. However, it may have any complex shape, especially with hard-to-reach corners.

[0043] [43] With the aid of the preceding device, the cleaning method of the present invention comprises the following main steps:

[0044] [44] Reduce the pressure in the enclos...

Abstract

The invention relates to a device for delicate treatment within a close chamber, comprising a duct, the first end of which is for connection to the inside of the chamber, further connected to a means for pressure reduction, the function of which is to generate a drop in pressure in the chamber, to an outlet duct to remove the aspirated material, to a duct connected to a device for sudden pressuredrop and to an opening in the device which permits contact of the end of the duct with the ambient air when the pressure within the chamber reaches a value below a certain threshold.

Description

technical field [0001] [01] The present invention relates to a method and apparatus for filling, purging, open-type insertion into a closed or virtually closed enclosure. The invention is particularly suitable for complex shaped and / or difficult to access cavities. It has many applications including construction, chemical or food production plants, medicine and dentistry. Background technique [0002] [02] To clean a closed enclosure, it is known practice to make two openings in the enclosure in order to circulate a fluid, gas or liquid, possibly with chemical cleaning properties, at high pressure therein. The method quickly reaches its bounds: [0003] [03] - For some complex shaped enclosures, the walls that cannot be reached by fluid and are not cleaned; [0004] [04] - Furthermore, simple cycles require relatively long cleaning times and generally exhibit mediocre effectiveness. [0005] [05] To fill an air-filled closed or semi-closed chamber with a fluid or viscous...
