Description
L'invention concerne une pompe à vide rotative à palettes convenant particulièrement à des utilisations dans l'industrie dans laquelle il est nécessaire de respecter certaines règles d'hygiène tant lors du fonctionnement de la pompe qu'en ce qui concerne les services de nettoyage.The invention relates to a rotary vane vacuum pump which is particularly suitable for use in industry in which it is necessary to comply with certain rules of hygiene both during the operation of the pump and with regard to cleaning services.
Les pompes à vide rotatives à palettes existent depuis longtemps. Dans de telles pompes, le rotor est muni de plusieurs lames (dénommées « palettes ») qui coulissent radialement et qui assurent le transfert de l'air pompé.Rotary vane vacuum pumps have been around for a long time. In such pumps, the rotor is provided with several blades (called "vanes") which slide radially and which ensure the transfer of the pumped air.
Dans la demande de brevet européen publiée sous le numéro
En effet, des liquides ou solides peuvent se déposer et stagner dans lesdites zones de rétention sur la surface de la pompe et donner ainsi lieu à des développements d'organismes pathogènes (champignons, bactéries, etc.) ce qui induit des risques de contamination.In fact, liquids or solids can be deposited and stagnate in said retention zones on the surface of the pump and thus give rise to the development of pathogenic organisms (fungi, bacteria, etc.) which induces risks of contamination.
Le document
Le but majeur de l'invention est donc de proposer une pompe à vide rotative à palettes qui ne présente pas les inconvénients susmentionnés et qui est notamment apte à être utilisée dans les environnements soumis à des normes strictes d'hygiène.The major aim of the invention is therefore to provide a rotary vane vacuum pump which does not have the aforementioned drawbacks and which is particularly suitable for use in environments subject to strict hygiene standards.
Ce but est atteint au moyen d'une pompe à vide rotative à palettes telle que définie par les termes de la première revendication. La pompe a comme particularité que toutes les surfaces de la pompe visibles depuis le haut sont agencées de manière à ce qu'elles soient dépourvues d'éléments susceptibles de retenir des liquides ou des solides. En particulier, cette pompe peut, au moins sur une partie, être munie de moyens de protection dépourvus de surfaces ou creux susceptibles de retenir des liquides ou des solides.This object is achieved by means of a rotary vane vacuum pump as defined by the terms of the first claim. The pump has the peculiarity that all the surfaces of the pump visible from the top are arranged so that they are devoid of elements liable to retain liquids or solids. In particular, this pump may, at least in part, be provided with protection means devoid of surfaces or hollows capable of retaining liquids or solids.
Une telle pompe a en outre l'avantage d'être facile à nettoyer. Elle convient ainsi tout à fait à des utilisations dans des industries dans lesquelles il est nécessaire de respecter certaines règles d'hygiène.Such a pump also has the advantage of being easy to clean. It is thus perfectly suitable for use in industries in which it is necessary to comply with certain hygiene rules.

Comme déjà mentionné, la pompe à vide rotative à palettes selon l'invention est caractérisée en ce que toutes ses surfaces visibles depuis le haut sont agencées de manière à ce qu'elles soient dépourvues d'éléments susceptibles de retenir des liquides ou des solides. De telles surfaces, qui sont nécessairement extérieures, peuvent être formées par des ailettes de refroidissement et elles sont situées sur la moitié supérieure de la pompe à vide, étant donné que les surfaces situées sur la moitié inférieure de la pompe à vide ne peuvent, en raison de la gravité, retenir un liquide ou un solide. A cet endroit, il semble important de préciser que les adjectifs « supérieur » et « inférieur » utilisés dans le présent texte (et ceci tant dans la description que dans les revendications) se réfèrent à la position normale de la pompe lorsqu'elle est en fonctionnement ou prête à fonctionner.As already mentioned, the rotary vane vacuum pump according to the invention is characterized in that all of its surfaces visible from the top are arranged so that they are devoid of elements capable of retaining liquids or solids. Such surfaces, which are necessarily exterior, can be formed by cooling fins and they are located on the upper half of the vacuum pump, since the surfaces located on the lower half of the vacuum pump cannot, in Due to gravity, retain a liquid or a solid. At this point, it seems important to specify that the adjectives “upper” and “lower” used in the present text (and this both in the description and in the claims) refer to the normal position of the pump when it is in operation. operating or ready to operate.
Pour réaliser les surfaces supérieures dépourvues d'éléments susceptibles de retenir des liquides ou des solides, il est notamment possible de façonner la partie supérieure des surfaces d'une manière lisse. Ceci peut se faire lors de la production des parties constituantes de la pompe, donc p.ex. lors de l'usinage des parois extérieures de la chambre de pompage.In order to achieve the upper surfaces devoid of elements liable to retain liquids or solids, it is in particular possible to shape the upper part of the surfaces in a smooth manner. This can be done during the production of the component parts of the pump, so for example during the machining of the outer walls of the pumping chamber.
Alternativement, la pompe peut aussi, au moins sur une partie, être munie de moyens de protection de la surface supérieure. Ces moyens de protection doivent également être dépourvus de creux, par exemple des rainures, situés sur la moitié supérieure de la pompe à vide et à l'intérieur desquels des liquides ou des solides pourraient stagner.Alternatively, the pump can also, at least in part, be provided with means for protecting the upper surface. These protection means must also be devoid of hollows, for example grooves, located on the upper half of the vacuum pump and inside which liquids or solids could stagnate.
Pour prendre connaissance d'un premier mode de réalisation de l'invention, on peut commencer par se reporter à la
Cette pompe comporte notamment un moteur d'entraînement, en l'occurence un moteur asynchrone qui est refroidi à l'air. Bien entendu, il serait possible d'utiliser un autre type de moteur, y compris un moteur refroidi à l'eau, suivant le modèle. Ce moteur est couplé à une chambre de pompage 2, en vue d'entraîner le rotor de cette dernière en rotation, afin que la pompe puisse remplir sa fonction de pompage. Un cylindre intermédiaire V2 connecte le moteur d'entraînement à la chambre de pompage 2 et il contient normalement les éléments de connexion entre le moteur d'entraînement et la chambre de pompage 2.This pump comprises in particular a drive motor, in this case an asynchronous motor which is air-cooled. Of course, it would be possible to use another type of engine, including a water-cooled engine, depending on the model. This motor is coupled to a
