Definitions
- the peristaltic pumps in which the hose is reset by negative pressure, are more complex in their construction, which is understandable due to the required vacuum-tight construction.
- Obtaining the negative pressure when installing the separating device depends on the vacuum-tight connection of the components moving relative to one another in the housing.
- the vacuum pump is completely filled with liquid, there is a risk that if the vacuum is too great, the ge present inside the housing of the hose pump rings amount of the required lubricant foams, so that the restoring forces re-erecting the hose can not be built up or only in a reduced size.
- the invention is therefore based on the knowledge that when the peristaltic pump is operated, air can be pressed out of the interior of the housing by squeezing this second tube together - in the same way as is done with the delivery hose, which creates a vacuum in the interior of the housing maintained or generated.
- This second hose can be very small in diameter.
- the hose available for the actual conveying does not need to be elastically deformable, but can be erected again by negative pressure, so that the advantages of a vacuum pump can be used.
- the second hose that is used to maintain or create of the vacuum inside the peristaltic pump can be arranged in the interior of the peristaltic pump in such a way that the first squeeze bodies, which serve to squeeze the delivery hose together, can also be used as the second squeeze bodies, which are present for creating or maintaining the vacuum. This brings a considerable simplification of the construction principle of such
- the hose pump according to the invention can only function fully when the required negative atmospheric pressure has built up inside. At the start-up time of such
- Hose is present within the wall of the first hose.
- the second hose is also laid at the same time. This ensures that the second hose is always in the correct position with respect to the first hose and thus to the existing squeeze bodies.
- Hose monitor for the main hose since it lies in the area at maximum risk and can therefore immediately indicate that the main hose is partially cracked and should therefore be replaced, since it is still at full capacity at the moment but it can be expected that the hose will be completely torn up in a more or less short time and will be destroyed.
- the hose can be used when conveying food the pump must be switched off before the main hose breaks, so that the pumped food cannot mix with the lubricating fluid inside the hose pump. Peristaltic pumps can now also be safely used to convey food.
- FIG. 1 shows a cross section through a peristaltic pump according to the invention
- a housing 10 of a hose pump has two nozzles, of which - in the drawing - the left nozzle as the suction nozzle 12 and - in the drawing - the right nozzle as the pressure nozzle 14.
- the direction of rotation 16 of a rotor 18 present in the housing 10 corresponds to the counterclockwise direction.
- This channel-like opening 32 of the hose 22 has an opening 44 in the area of the suction nozzle 12, which opens into the interior 46 of the housing 10, in the upper area thereof.
- the channel-like opening 32 has an airtight connection with an outlet channel 50, which exits to the atmosphere with its other end outside the housing 10, whereby it pierces the sealing ring 52.
- the pressure port 14 has at its upper end
- the channel-like opening 32 is also at these points of the tube 22 by the Squeeze body 26 fully squeezed together and thus closed. Should the hose 22 tear over time, such a crack formation will first appear on the inside in the area of the bending areas 40, 41. Since the channel-like opening 32 is also located in one of these areas, such a crack would open the channel 32 inwards, so that the channel-like opening 32 would no longer exist as such. In that state it would be
- Hose 22 but still fully functional; only the medium to be conveyed through the interior of the hose 22 would emerge from the outlet opening 50 instead of air.
- I would leak part of this soup, for example, when conveying soup from the outlet channel 50.
- the peristaltic pump could thus be switched off at a time when the
