Definitions

  • the invention relates to an apparatus for cleaning tubular elements.
  • the invention is usefully applied for cleaning and decontaminating rigid or flexible pipes which are part of machines or plants mainly used in the pharmaceutical, chemical and/or food industries which, at the end of a production spell have to be decontaminated (therefore carefully washed, dried and in some cases sterilised or at least left in a very hygienic state).
  • Prevalently modern plants and machines are provided with systems for cleaning in place, which enable cleaning to be done without having necessarily to dismantle the plants or machinery.
  • the plants or machinery are normally provided with a series of auxiliary apparatus, constituted in particular by flexible or rigid pipes which are predisposed for connecting various plants or apparatus up to one another for transporting raw materials, semi-finished materials or indeed finished products, and must obviously be well cleaned and decontaminated.
  • the main aim of the present invention is obviate the limits and drawbacks inherent in the prior art, providing space saving for carrying out the cleaning operations, a considerable energy saving, and a saving of liquid used for washing, and offers greater utilisation of the plants together with a corresponding saving in terms of work hours of personnel.
  • An advantage of the invention is the possibility of carrying out a decontamination operation directly in the place where the pipes are used.
  • a further advantage of the invention is to enable a drastic reduction in the consumption of washing water and clean water for rinsing.
  • a still further advantage consists in using a contained and isolated space for the cleaning operations (a closed chamber) in which the operative personnel does not require special protection devices. The leads to considerable saving of space, energy and working hours, and the personnel does not need to don special individual protection devices.
  • figure 1 is a schematic frontal view in partially-sectioned vertical elevation
  • figure 2 is a schematic plan view from above of figure 1.
  • 1 denotes a chamber which is conformed in order to receive a tubular element 2 arranged at a lie which is identified by a predetermined arrangement of its axis with respect to a longitudinal axis x-x of the chamber 1, which is elongate in shape in the direction of the longitudinal axis x-x.
  • the chamber 1 is equipped with a plurality of washing nozzles 14 and with at least one nozzle 10 which is located in a central position and which is mobile at least in a parallel direction to the longitudinal axis x-x of the chamber 1.
  • the chamber 1 is closed and comprises: a first outlet 11 for draining off the washing liquids; a second outlet 12 for enabling evacuation of the humid air; an inlet 13 for enabling introduction of a gas for drying.
  • the chamber 1 is further provided with an opening, normally closed by a hatch, through which one or more tubular elements 2 can be introduced in the chamber 1.
  • the hatch is constituted by a conical cover 25, and the inlet 13 is predisposed in the cover 25 itself.
  • the chamber 1 has a telescopic structure, which enables a length thereof to be varied in a direction of the axis x-x. This enables an adjustment of the length of the chamber 1 to the length of the tubular elements to be received.
  • the chamber 1 rests on the ground in the following way: it is inferiorly hinged by a horizontal pivot 20 to a support 21 and also rests on a height-adjustable support 22 having a function of arranging the chamber 1 at a desired inclination about the pivot 20.
  • the support 21 and the adjustable support 22 can be fixed to an underlying frame 23 which can be simply rested on the ground or can be mounted on wheels so as to enable easy transport of the whole chamber 1.
  • the nozzles 14 of the plurality of nozzles 14 are distributed peripherally around at least a part of the lateral walls of the chamber 1.
  • the mobile nozzle 10 inserts coaxially internally of a tubular element 2 housed internally of the chamber 1 , and is provided with a plurality of holes for wasliing liquid to exit therefrom (the washing liquid is usually water).
  • the holes are orientated in order that the reactions of the jets support the mobile nozzle 10 when it is inside the tubular element 2.
  • the mobile nozzle 10 is directly mounted at an end of a flexible tube 15 through which it is supplied with pressurised liquid.
  • This flexible tube 15 is mounted on a winding reel 16 by means of which the two-way movements of the mobile nozzle 10 can be controlled, parallel to the axis of the tubular element 2 internally of which the mobile nozzle 10 is inserted.
  • the reel 16 is located externally of the chamber 1.
  • the flexible tube 15 runs slidably and sealedly through an aperture 17.
  • the aperture 17 is arranged coaxially to the longitudinal axis x-x of the chamber 1 in a position which is diametrically opposite the position of the second outlet 12 for evacuation of humid air.
  • the unwinding and rewinding of the flexible tube 15 on the reel 16 determine the axial displacement of the nozzle 10 along the axis of the tubular element 2, and therefore also determine the internal washing action.
  • the winding and unwinding are controlled electronically and can be set automatically on the basis of the pre-set washing programme for the tubular element 2 which is to be washed.
  • the washing of the external surfaces of the tubular element 2 is done by means of the external nozzles 14, which are normally in fixed positions. Discharge of the waters or liquids used for washing and rinsing is achieved through the outlet 11 towards which the liquids are sent by inclining the chamber 1 which is located in a diametrically opposite position to a position at which the outlet 12 for the evacuation of the humid air is located.
  • a self-priming pump 24 extracts the liquids.
  • Immediately downstream of the outlet 11 there are devices for qualitative and quantitative measurement of the contaminating agents present in the liquid used for the washing operation which, in the illustrated embodiment, can be constituted by conductivity and resistivity measurement devices which enable continuous monitoring of the discharged liquids.
  • a drying gas is introduced through the inlet 13, which is located in a diametrically opposite position to the outlet 12 for evacuating the humid air.
  • the gas is produced by a fixed or mobile generator of hot and/or cold and/or gas- sterilised filtered air, according to needs.
  • the invention enables washing, drying and sterilising of tubular elements without having to move them, and further enables execution of these operations in non- specialist environments - while nonetheless avoiding pollution.
  • the invention is provided with adequate instrumentation for reading and transmitting all of the process parameters to remote data processing systems (e.g. PLC or PC), thus guaranteeing the best possible guarantee that the parameters read are reproducible and the final reports fully reliable. Furthermore, the whole system is mobile and telescopic and enables one positioning only of the tubular element to be internally washed, externally washed, made hygienic and/or sterile.

Abstract

L'invention concerne une chambre (1) conçue pour recevoir un élément tubulaire (2) disposé dans une position qui correspond à un arrangement prédéterminé d'un axe dudit élément tubulaire par rapport à un axe longitudinal de la chambre (1). La chambre (1) est munie d'une pluralité de buses de nettoyage dont au moins une (10) est située dans une position centrale et peut se déplacer au moins dans une direction parallèle à l'axe longitudinal de la chambre (1), de façon à pouvoir être insérée coaxialement à l'intérieur d'un élément tubulaire (2). La chambre (1) est fermée et comprend : une première sortie (11) servant à drainer les liquides utilisés pour le nettoyage ; une entrée (13) permettant d'introduire un gaz de séchage et/ou de stérilisation ; une seconde sortie (12) permettant d'évacuer l'air humide. L'appareil selon l'invention est équipé d'instruments qui peuvent lire et transmettre tous les paramètres relatifs aux liquides sortants à des systèmes de traitement de données tels que des ordinateurs personnels ou des automates programmables.
