Definitions
- the present invention relates to a self-cleaning pump for hygiene-sensitive applications.
- the invention further relates to a method for operating a self-cleaning pump.
- a self-cleaning pump of the type mentioned is used, for example, for hygiene-sensitive applications in the food industry, in the pharmaceutical sector, in the semiconductor field or in pure (st) raumanengineen to ensure that prescribed in an interior of the pump hygienic conditions, such as those in the food sector for A certification according to EHEDG is required.
- Self-cleaning pumps - for example, so-called CIP (Cleaning in Place) - capable pumps - are used, for example, in coffee machines.
- US 3,450,052 A describes a self-lubricating pump with an air flowed through by a pumped interior, with a conveyor channel through which the fluid is conveyed, with a suction side and a pressure side, wherein between the suction side and the pressure side a pumping device for conveying the fluid is arranged, and with a drive motor whose drive shaft is drivingly coupled to a conveying element of the pumping device, wherein on the suction side of the conveying channel a removal point is provided, through which a subset of the conveying medium for lubricating bearings of a plurality of conveying elements can be removed.
- An object of the present invention is to provide a self-cleaning pump whose interior is flushed continuously and automatically as well as efficiently and reliably during its operation.
- a self-cleaning pump with the features of claim 1 and in particular by the fact that on a suction side of the conveying channel a removal point is provided, through which a subset of the pumped medium for flushing the interior can be removed.
- a second pumping device is preferably provided by means of which it can be actively conveyed through the interior of the pump to be cleaned in order to flush the interior space.
- the second pumping means may be designed to suck the conveying medium at the removal point out of the conveying channel.
- the energy consumption of such a second pumping device is significantly less than the amount of energy that must be applied to pressurize the fluid - as known from the prior art - by a main pumping device and then a portion of the pressurized fluid for flushing the interior to use.
- the invention is based on the general idea, the subset of the pumped medium for flushing the interior not - as previously known - on the pressure side, but on the suction side, because the subset of the pumped liquid is not yet set by the high energy expenditure under pressure on the suction side , For flushing the interior of the pump thus considerably less energy is needed than is the case with previously known self-cleaning pumps.
- an outlet point is provided on the suction side of the conveying channel, through which the subset of the conveying medium used for rinsing the interior can be fed to the conveying channel.
- the supply of the pumped medium used for flushing to the outlet point can be done exclusively on the bearing gap of the rotor bearing or - additionally or alternatively - via a dedicated channel.
- a structurally particularly simple embodiment provides to form a conveying element of the main pumping device as a gear.
- the pump may be designed as an internal gear pump or preferably as an external gear pump.
- the main pumping device may alternatively be designed as a vane pump.
- the interior may include a pumping space for receiving the main pumping means and an engine compartment for receiving a rotor of the driving motor which are in fluid communication with each other and which are sealed together against the environment.
- the rotor of the drive motor can be arranged completely in the interior to be cleaned.
- the stator of the drive motor can be arranged completely outside the interior to be cleaned.
- the pump may comprise a base part, a cover plate and a containment shell, the base part and the cover plate at least substantially forming or defining the pump space and the cover plate and the containment shell at least substantially forming or defining the engine space.
- the pumping space may be formed between the base part and the cover plate
- the engine compartment may be formed between the cover plate and the containment shell.
- the second pumping device is arranged in the engine compartment, as a result, a compact design can be achieved.
- the second pumping means is drivingly coupled to the drive motor.
- the power for operating the second pumping means is provided by the drive motor of the pump.
- the drive motor may be coupled directly or indirectly with the second pumping device.
- a delivery point for dispensing the subset of the pumped medium for flushing the interior can open into the engine compartment.
- it is arranged on a side facing away from the pumping device of the rotor.
- the delivery point is preferably formed centrally on the rotor. This has the advantage that the rotor is reliably washed around.
- the second pumping means comprises a scavenging flow generator element, which is rotatably coupled to the rotor in order to promote the subset of the pumped medium through the interior of the pump to be cleaned.
- This flushing current generator element is advantageously integrally connected to the rotor, for example ultrasonically welded.
- the second pumping device can have at least one blade-preferably a plurality of blades-which are designed to generate a vacuum necessary for removing the partial quantity of the pumped medium and to distribute the medium uniformly in the interior space.
- the second pumping device can be designed as a flow pump, in particular as an axial pump.
- the purge flow generator element is arranged on a side remote from the conveyor channel side of the rotor. This ensures that the subset of the medium used for flushing the interior evenly flows around the rotor before it is passed back into the conveyor channel.
- the first conveyor element, the rotor and the purge flow generator element may be coaxial with one another and, in particular, coupled to a common shaft, whereby a direct torque transfer from the rotor to the first conveyor element and the purge flow generator element can be effected.
- the conveying element, the rotor and / or the flushing-current generator element can be coupled in a rotationally fixed manner to a hollow shaft, which is in fluid connection on the input side with the removal point and on the output side with the interior to be cleaned, in particular the engine compartment, is in fluid communication.
- a hollow shaft which is in fluid connection on the input side with the removal point and on the output side with the interior to be cleaned, in particular the engine compartment, is in fluid communication.
- the hollow shaft is in particular indirectly in connection with the removal point, for example via a channel.
- the shaft or hollow shaft is preferably held by the conveyor element, in particular a gear, in the axial direction for easy storage.
- the pumping means may be formed as a gear pump, which comprises a first and a second gear, wherein the first gear corresponds to the first conveying element and the second gear is arranged on a second hollow shaft, the input side in fluid communication with the removal point and on the output side with the interior, in particular the pump space, is in fluid communication.
- a gear pump which comprises a first and a second gear, wherein the first gear corresponds to the first conveying element and the second gear is arranged on a second hollow shaft, the input side in fluid communication with the removal point and on the output side with the interior, in particular the pump space, is in fluid communication.
- a third pumping device may be provided, which is assigned to the second gearwheel and which is coupled to the rotor in an effective manner, in particular via the first gearwheel. In this way, a part of the interior can be rinsed in the region of the second gear.
- a separate suction-side removal point for the subset of the pumped medium can be provided for rinsing the part of the inner space in the region of the second toothed wheel. It is also conceivable, however, that this subset is taken from the delivery channel via the removal point assigned to the second pumping device.
- the third pumping means may comprise a second flushing flow generating element, which is rotatably coupled to the second hollow shaft.
- the second purge flow generator element is preferably formed integrally with the second gear.
- a flow-conducting pin may be provided, which projects into the hollow shaft and is advantageously arranged substantially coaxially with the hollow shaft.
- the pin is preferably formed on the cover plate.
- a pressure sensor may be arranged on the pressure side of the conveying channel.
- Self-cleaning pumps on the market usually do not allow this, as the pressure-side standpipe is located at the place predestined for this purpose.
- the data collected by the pressure sensor may be used to monitor and / or regulate the pressure that the pump generates.
- the second subset of the pumped medium reaches a minimum flow rate of 1.5 m / s, preferably a minimum flow rate of 2 m / s when purging the interior in all areas of the interior.
- turbulent flow conditions prevail in the interior space in substantially all areas.
- the return of the second subset of the pumped medium in the delivery channel can be done on the suction side.
- the removal of the second subset of the pumped medium is effected by suction by means of a flushing flow generator element which - directly or indirectly - driven by a drive motor of the pump, in particular driven to a rotary motion, is.
- the second subset of the pumped medium can be sucked through a hollow shaft.
- the hollow shaft is advantageously rotated about its axis, whereby the flushing power generator element is rotated and the second subset of the conveying medium is sucked by means of the flushing power generating element.
- a conveying element used to convey the first subset of the conveying medium-the main conveying stream- is driven by the rotation of the hollow shaft.
- the flushing of the entire interior occurs during operation of the pump continuously and / or automatically.
- the pressure on the pressure side in the delivery channel can be measured.
- the figures show a self-cleaning pump 10, which is designed in the manner of an external gear pump.
- the pump 10 is particularly suitable for applications in which the entire interior 12 of the pump 10 must meet high hygiene standards, for example for certification according to EHEDG.
- the pump 10 operates on the principle that a subset of the pumped liquid is removed at a suction side 14 of a conveyor channel 16 and is conveyed through the entire interior 12 of the pump 10 in order to flush the interior 12 continuously. This avoids, among other things, that the delivery medium - for example, milk or drinking water - is left in the pump 10 for a longer period of time and can thus form germs.
- Fig. 1 shows the pump 10 in a sectional view along a conveying direction 18.
- the pump 10 comprises three housing parts which define together to be flushed interior 12: a base member 20, a cover plate 22 and a split pot 24.
- the three parts 20, 22, 24 are detachable connected to each other and each sealed to each other by means of seals 21, so that the defined by the three parts 20, 22, 24 interior 12 is sealed against an environment 26 of the pump 10.
- a drive motor 28 designed as a brushless electric motor is provided with a stator 30 arranged completely outside the gap pot 24 and a rotor 32 arranged completely within the gap pot 24.
- An inner contour of the base part 20 defines the delivery channel 16 and a - in the present example substantially centrally in the delivery channel 16 arranged pumping space 36.
- the pumping space 36 takes - as in Fig. 2 Good to see - a first gear 38 and a second gear 40, which mesh with each other and which are driven in operation by the drive motor 28 - directly or indirectly - driven.
- the base part 20 further defines a pump inlet 42 and a pump outlet 44, to each of which a clamping device 46, 48 is arranged. With the help of the clamping devices 46, 48, a hose 50 for supplying the pumped medium is attached to the pump inlet 42 and attached to the pump outlet 44 is a hose 52 for discharging the pumped medium.
- connection may be provided between the hoses 50, 52 and the pump 10 (e.g., a threaded connection).
- the conveying medium is conveyed through the conveying channel 16 in a known manner.
- the region in which the fluid is not yet pressurized referred to as the suction side 14 and the region in which the fluid was pressurized by the pumping device 54, referred to as the pressure side 56.
- the interior 12 to be purged of the pump 10 shown comprises, inter alia, two partial spaces: an engine compartment 12a (cf. Fig. 2 ), which extends between the rotor 32 and the split pot 24 and a space 12b in the region above the second gear 40.
- an engine compartment 12a cf. Fig. 2
- a subset of the conveying medium is conveyed to flush these subspaces 12a, 12b.
- a removal point 58 (shown in phantom) is formed.
- the removal point 58 seen in the conveying direction 18 in front of the axes of rotation of the gears 38, 40 (see. Fig. 5B ) and thus arranged on the suction side 14, begin two spaced apart and V-shaped to each other discharge channels 60, 62, which conduct a required to purge the interior 12 portion of the pumped medium to a lower end of a first hollow shaft 64 and a second hollow shaft 66 (see. Fig. 2 ).
- the lower portions of the hollow shafts 64, 66 are supported by bearings 83 arranged in depressions 65.
- the necessary for flushing the interior 12a subset of the pumped liquid is from a second pumping device 68 (see. Fig. 1 and 2 ) via the removal point 58 and sucked through a removal channel 60 and the hollow shaft 64.
- the second pumping device 68 comprises a first flushing-current generator element 70, which is connected in a material-locking manner to the rotor 32 of the drive motor 28 by means of ultrasonic welding on the end face of the rotor 32 facing away from the conveying channel 16.
- the welded connection is designed so that no pumped medium can penetrate into recesses 72 formed in the rotor 32, in which permanent magnets 74 are arranged.
- the purge generator element 70 accordingly acts as a type of hermetic lid for the recesses 72.
- the rotor 32 side facing away from the first Spülstrom Wegerelements 70, as in Fig. 6A can be seen, formed eight star-shaped blades 76.
- the blades 76 are each curved and have a rounded top.
- a receptacle 78 is formed for the first hollow shaft 64, wherein the receptacle 78 is aligned with a discharge point 80 formed in the first flushing-current generator element 70.
- the fluid flows into a recess 82 (see FIG Fig. 7A and 2 ), which at the Top of the cover plate 22 is formed.
- the recess 82 rotates about the hollow shaft 64 in about half and the depth decreases in the course in Fig. 7A from left to right. It communicates with an opening 81 which connects the hollow shaft 64 and a bearing 83 which supports the shaft 64 in the cover plate 22 (cf. Fig. 2 ).
- the channel 85 can also lead separately from the opening 81 through the cover plate 22.
- the medium flows into a at the bottom of the cover plate 22 (see Fig. 7C ) formed outlet channel 84 and then to the - as the removal point 58 - located on the suction side 14 outlet 86.
- a second Spülstrom Wegerelement 88 is formed, which takes a subset of the pumped liquid for flushing the interior 12b at the removal point 58 and sucks through the second removal channel 62 and the second hollow shaft 66 and in the subspace 12b distributed.
- the second purge flow generator element 88 (see Figs. 5A and 5B ) has blades 90 which extend in a straight line in the radial direction.
- a pressure sensor 96 is provided, which is adapted to measure the pressure of the pumped fluid at the pressure side 56.
- Figs. 8A and 8B clarify once again the flow pattern of the pumped medium used for flushing, ie the purge stream, through the interior 12 of the pump 10.
- the purge stream is divided into two partial streams.
- the removal channels 60, 62 are not spaced apart, but converging, formed in the base member 20.
- a first partial flow flows through the first removal channel 60 from below into the first hollow shaft 64 and through this up to the discharge point 80.
- the discharge point 80 distributes the first Spülstrom Wegerelement 70, which generates the medium sucking the pumping medium, the first partial flow evenly in the upper Section of the engine compartment 12a.
- the first partial flow From there flows the first partial flow - entrained by the rotation of the rotor 32 - spiral down. At the lowest point of the engine compartment 12a, the first partial flow flows via the depression 82 and the channel 85 into the first outlet channel 84, which guides the first partial flow to the outlet point 86.
- a second partial flow flows through the second withdrawal channel 62 from below into the second hollow shaft 66 and through this up to a second discharge point 80.
- the second purge stream generator element 88 distributes the second partial stream in the interior 12 b. After the second partial flow has flushed through the interior space 12b, it also flows via the second outlet channel 94 back to the outlet point 86.
- the above flushing concept ensures a reliable and - when the pump is in operation - continuous flushing of the interior while at the same time achieving high efficiency of the pump.
- the constructive implementation of the concept is very compact, in particular since the media streams used for rinsing are guided by the hollow shafts carrying the pump components and since the pump devices which serve to generate the negative pressure required for conveying said media streams are provided in the engine compartment or at the hollow shaft end.
