Abstract
Description
La présente invention concerne le domaine du nettoyage de pompes de liquides, par exemple alimentaires, comme plus particulièrement du lait. De telles pompes sont connues de l'état de la technique, notamment par les brevets allemands DE10043668 ou DE20313360, ou encore la demande de brevet américain US2004/011647 ou le brevet anglais GB852580.The present invention relates to the field of cleaning pumps of liquids, eg food, as more especially milk. Such pumps are known to the state of the art, in particular by German patents DE10043668 or DE20313360, or the patent application US2004 / 011647 or GB852580.
L'invention a pour but de munir des pompes à liquide d'aménagements permettant d'éviter qu'elles ne tournent pendant les phases de lavage. Il est ainsi possible de ne pas avoir d'automatés ou d'installations spéciales, notamment en station de lavage, de façon à autoriser la rotation des pompes pendant le lavage.The purpose of the invention is to provide liquid pumps arrangements to prevent them from turning during the washing phases. It is thus possible to not have automation or special facilities, especially in the washing station, so as to allow the rotation of the pumps during washing.
Ce but est atteint grâce à une pompe comprenant deux gorges latérales sur les faces avant et arrière du corps de pompe avec une communication interne basse et haute entre ces deux gorges.This goal is achieved thanks to a pump comprising two side grooves on the front and back sides of the body of pump with low and high internal communication between these two throats.
Avantageusement, la communication interne basse et haute se présente sous la forme de deux gorges de communication entre lesdites gorges latérales.Advantageously, the internal communication low and high is in the form of two throats of communication between said lateral grooves.
De préférence, ladite communication interne basse et haute relie les gorges latérales avec l'entrée et la sortie de liquide.Preferably, said internal communication is low and high connects the lateral grooves with the entry and the exit of liquid.
L'invention concerne tout particulièrement des pompes centrifuges, mais l'aménagement ci-dessus peut s'appliquer à tout autre type de pompe adapté à ce type d'aménagement, comme des pompes MGM35.The invention particularly relates to pumps centrifugal, but the above arrangement may apply to any other type of pump adapted to this type of arrangement, like MGM35 pumps.
L'invention concerne aussi la fabrication des pompes ci-dessus consistant à aménager deux gorges latérales sur les faces avant et arrière du corps de pompe avec une communication interne basse et haute entre ces deux gorges. The invention also relates to the manufacture of pumps above consisting in arranging two lateral grooves on the front and rear faces of the pump body with a low and high internal communication between these two throats.
L'invention concerne encore un dispositif comprenant plusieurs pompes du type décrit ci-dessus.The invention further relates to a device comprising several pumps of the type described above.
L'invention est tout particulièrement adaptée à offrir un moyen de lavage des pompes efficace dans les laiteries, où tant les pompes que les tuyauteries et les cuves doivent être nettoyées après chaque utilisation.The invention is particularly suitable for offering effective pump washing means in dairies, where both pumps and pipes and tanks must be cleaned after each use.
D'autres avantages et caractéristiques de l'invention apparaítront des exemples ci-après où il sera fait référence aux dessins en annexe dans lesquels :
- La figure 1 représente une vue générale d'un système de pompage duplex avec ses organes de lavage.
- Les figures 2 et 3 représentent une vue en coupe d'une pompe munie de l'aménagement selon l'invention.
- Figure 1 shows a general view of a duplex pumping system with its washing members.
- Figures 2 and 3 show a sectional view of a pump provided with the arrangement according to the invention.
La figure 1 représente une vue générale d'un système de pompage duplex comprenant deux pompes (100, 200), une pompe centrifuge (100) et une pompe (200).Figure 1 represents a general view of a system duplex pump comprising two pumps (100, 200), a centrifugal pump (100) and a pump (200).
Le système comprend un premier circuit comprenant un conduit d'entrée (101) débouchant dans l'embout d'entrée (102) de la pompe centrifuge (100). La sortie de la pompe (100) débouche dans un conduit (103) communiquant avec la sortie principale (104) du système, ainsi qu'avec un conduit secondaire (201) débouchant dans l'entrée de la pompe (200).The system includes a first circuit comprising a inlet duct (101) opening into the inlet nozzle (102) of the centrifugal pump (100). The output of the pump (100) opens into a conduit (103) communicating with the main output (104) of the system, as well as with a conduit secondary (201) opening into the inlet of the pump (200).
Le circuit primaire comporte un clapet anti-retour (105).The primary circuit has a non-return valve (105).
La sortie de cette pompe (200) est reliée à la sortie du système de pompage par un conduit (202).The output of this pump (200) is connected to the output the pumping system through a conduit (202).
Le circuit secondaire comporte un clapet anti-retour (203). The secondary circuit comprises a non-return valve (203).
La sortie (103, 104) du circuit principal comprend des sorties de purge commandées par des robinets de purge (2, 4).The output (103, 104) of the main circuit comprises purge outlets controlled by purge valves (2, 4).
De même, le circuit secondaire comprend également des sorties de purge commandées par des robinets (1, 3, 5, 6).Similarly, the secondary circuit also includes purge outputs controlled by faucets (1, 3, 5, 6).
Pendant le pompage, on ferme les vannes (1, 2) ainsi que tous les robinets de purge (3, 4, 5, 6). Puis pendant le lavage, on ouvre les vannes (1, 2) de façon à permettre l'entrée et la sortie du liquide de nettoyage, par exemple constitué d'eau chaude et de soude, et on ferme tous les robinets de purges (3, 4, 5, 6). Après le lavage, on ouvre à nouveau tous les robinets de purge (3, 4, 5, 6).During pumping, the valves (1, 2) and than all purge valves (3, 4, 5, 6). Then during the washing, the valves (1, 2) are opened to allow the entry and exit of the cleaning liquid, for example consisting of hot water and soda, and we close all purge valves (3, 4, 5, 6). After washing, we open again all the purge valves (3, 4, 5, 6).
Les figures 2 et 3 représentent des vues en coupe d'une pompe centrifuge susceptible d'être mise en oeuvre dans le système de la figure 1. Cette pompe comprend deux gorges latérales (7, 8) et une communication interne basse et haute se présentant sous la forme de deux gorges de communication (9, 10) entre lesdites gorges latérales (7, 8).Figures 2 and 3 show sectional views a centrifugal pump that can be used in the system shown in Figure 1. This pump has two grooves lateral (7, 8) and low and high internal communication in the form of two communication grooves (9, 10) between said lateral grooves (7, 8).
