Definitions
- the present invention relates to a peristaltic pump with the Features of the preamble of claim 1.
- Peristaltic pumps are generally pumps with a pump housing, in which a tube is annular along the inside of a Housing wall is applied.
- a rotor is inside the pump housing provided by circumferential squeezing of the hose along the inner wall a peristaltic promotion of the Hose content causes from a suction side to a pressure side.
- This task is performed by a peristaltic pump with the features of claim 1.
- the means for generating the vacuum is one of the rotor operable and arranged in the pump chamber diaphragm pump include, the required for vacuum generation assembly include few components.
- the diaphragm pump on the Inside a side wall is arranged, it can for maintenance purposes to be taken out with the side wall. Furthermore the membrane becomes with the negative pressure in the housing acted upon, so that the restoring force and thus the Suction capacity of the diaphragm pump is increased.
- the diaphragm pump is a diaphragm and a diaphragm carried by the diaphragm Wear part, wherein the wearing part in Operation intermittently by a slider connected to the rotor a force is applied to this wear part be easily replaced without others To change components.
- the interior of the diaphragm pump is expediently on the one hand by the membrane and on the other hand limited by the side wall.
- the interior of the Diaphragm pump can be connected to the pump chamber via a suction line and be connected via a pressure line to the atmosphere.
- the suction line and the pressure line are expediently associated with the check valves.
- the check valves are convenient for easy maintenance outside of the pump chamber arranged.
- FIG 1 is a hose pump according to the invention in one Front view along the axis of rotation of the (not visible here) Rotor shown.
- the peristaltic pump includes a pedestal 1, on which a pump housing 2 is arranged.
- the pump housing 2 in turn has an approximately circular cross-section on and is frontally bounded by a removable side wall 3.
- the side wall 3 carries a suction line 4 and a Pressure line 5 for an internal diaphragm pump.
- That behind the Sidewall 3 lying annular pump housing carries on a suction nozzle 6 and a discharge nozzle 7 for connection external lines.
- the side wall 3 is gas-tight with the annular pump housing bolted and with stiffening on the outside Ribs 8 provided.
- FIG. 2 shows the peristaltic pump shown in FIG a top view. Same components bear the same reference numbers.
- the annular pump housing 2 can be seen, that on its side wall 3 opposite side surface 10 carries a gear 11 and an electric motor 12.
- a section III the housing 3 is partially cut shown.
- rotatable rotor 14 illustrates a slider 15 carries.
- the side wall 3 carries on its inner side 16 a Diaphragm pump 17.
- the diaphragm pump 17 is via a through-bore 18 with the suction line 4 and a through hole 19 connected to the pressure line 5.
- the suction line 4 and the pressure line 5 in turn each carry a check valve 20 or 21.
- the section III is shown enlarged in the figure 3.
- FIG. 4 shows the section according to FIG. 3 in a further enlarged and simplified representation.
- the diaphragm pump 17 is an approximately annular or dome-shaped membrane 30 made of a rubber-elastic Material has.
- the membrane 30 is in an annular Mounted holder 31 and bolted to the side wall 3.
- the membrane 30 defines an interior 32, which communicates with the through-holes 18 and 19 communicates.
- the membrane 30 carries a wear plate 33, the diaphragm 30 towards the here not shown rotor 14 substantially covers.
- the wear plate 33 is drawn on the circumference.
- the membrane 30 may be made of an elastomer be made.
- the rotor 14 may also be made of aluminum are manufactured while the slider 15 wear resistant should be interpreted, for example made of steel.
- a vacuum-resistant suction hose connected for the medium to be delivered.
- a hose extends from the suction nozzle 6 along the periphery of the housing 3 on the inside thereof to the Discharge port 7.
- a delivery hose connected for the medium to be delivered.
- the rotor 14 in the interior of the pump housing 3 is approximately bar-shaped trained and pushes the inside of the pump Hose to the annular inside of the housing 2, so that upon rotation of the rotor, that in the tube segment The rotor located medium pressed through the hose and is conveyed to the discharge nozzle 7. Behind the rotor 14 is during operation of the hose located inside the pump his own elasticity strives to expand again.
- the resulting at the suction nozzle 6 vacuum can first only be as great as the return force of the pump hose it allows.
- the pump described so far corresponds to the state of the technique.
- a vacuum is generated inside the pump, which is the automatic expansion of the pump hose on the Supported suction side.
- the diaphragm pump 17 is provided. This one will with each revolution of the pump rotor of the slider with applied to an outward force, if namely the slider 15 with the orbital motion of the rotor 14th moved past the diaphragm pump 17 over. At this moment meets the slider 15 on the wear plate 33 and pushes the Wear plate 33 and thus also the membrane 30 on the side wall 3 too.
- the interior 32 is reduced in size.
- the im Interior 32 contained gas can because of the check valve 20 does not escape through the suction line 4, but is in the pressure line 5 and through the check valve 21 in the Atmosphere pressed.
- the suction line 4 is now with its through hole 18th opposite end connected to the pump housing 2 in such a way that the line 4 with the interior of the hose pump in conjunction stands, in which the pump hose is located.
- each Operation of the diaphragm pump 17 thus promotes a part of in the interior of the pump housing 2 located gas to the outside into the atmosphere, so that over time a negative pressure in the Pump housing 2 is formed. This negative pressure is in turn desirable to the pump hose in its return movement support.
- the negative pressure in the pump housing 2 that is, where the diaphragm pump 17 is arranged, but not only supports the suction hose and thus the peristaltic pump itself during the suction process. Rather, the vacuum located in the pump housing 2 is also on the side facing away from the interior 32 of the membrane 30 and consequently also supports the membrane 30 in their Restoring movement.
- the return force of the diaphragm 30, the for between the intake 4 and the pressure line. 5 achievable pressure difference is essential, so by the supported arrangement described.
- Diaphragm pump becomes an internal pressure in this way achieved in the housing 2 in operation of about 100 mbar absolute pressure.
- the slider 15 opposite the wear plate 33 as a wear-resistant component is designed may be a maintenance of the diaphragm pump 17 thereon restrict, with removed side wall 3, the retaining ring 31, the diaphragm 30 and the wearing part 33 to replace.
- These components are relatively easy and inexpensive to manufacture. If necessary, it is also sufficient, only the membrane 30 and the wear part 33 to change. Maintenance work on the rotor 14 or the slider 15 are not in general required.
