Definitions
- the invention relates to a discharge head for media, which in particular should have means for precisely controlled flow influencing of at least one medium, in order to be able to convey this medium, if necessary by hand-operated pumping, within narrow tolerances of flow rate and / or volume per unit of time.
- the discharge head should have means for merging at least two separately supplied or stored media, which may be different components of the same and / or different physical state and at the latest in the area of the discharge from an outlet opening with one another chemically or physically, for. B. interact through mixing.
- the media in particular a gaseous and a liquid medium, should preferably cooperate in such a way that foam with precisely determinable properties, for example a very stable, finely structured foam, is produced.
- a manually operable discharge device can be provided, with which air and liquid are brought together and then pressed through a porous, permeable body.
- the discharge device can e.g. be suitable for numerous applications, in particular for easy-to-foam, flowable media.
- the invention is further based on the object of creating a discharge head of the type mentioned, with which media which are relatively difficult to mix or foam can be brought together in such a way that a very precise structure of the mixing, preferably a particularly homogeneous mixing, can be achieved.
- At least one medium before, in particular immediately before the flow stabilization, e.g. subject to the fact that the flow rate is suddenly reduced.
- at least one medium can also be combined in a plurality of separate flow jets with at least one further medium, the medium expediently being exposed to the flow calming immediately before the combination as an undivided volume flow and then divided into the individual flow jets.
- the media are advantageously brought together only immediately adjacent to or on at least one permeable sheet, such as a sieve, which is made like a sponge.
- REPLACEMENT LEAF It can be wetted or soaked with the liquid medium at least on the input side in such a way that its through openings are spanned with the liquid medium in the manner of liquid films. These openings can have a width of the order of about a hundredth of a millimeter or less, for example half a hundredth of a millimeter.
- the sieves can be stamped parts from a flat sieve material made of plastic or the like. and be assembled into a multi-layer sieve pack.
- Adjacent sieve bodies can lie flat against one another and / or a small gap distance approximately in the order of their thickness of e.g. have significantly less than one millimeter from each other, which enables cross currents and, if necessary, transverse expansions of the foam that forms between the inlet side and the outlet side within the entire sieve arrangement along the sieve surface.
- their sieve openings are offset from one another in such a way that opening separations of one sieve cross openings of the other sieve.
- a gap of the order of magnitude mentioned can be provided on the input side of the screen body.
- all the inlet openings associated with the merging for at least two media lie in a common surface or plane which is approximately at right angles to the direction of flow and to which the sieve body adjoins at a constant distance or in a flat manner; the side of the screen body facing away from it forms the outlet, so that flow paths which are several times longer and approximately rectified in parallel or in alignment are formed before and after the screen body.
- the gaseous medium is expediently supplied through at least one ring of relatively small openings, which surrounds a single or a plurality of substantially larger openings for supplying the liquid medium and is very close to the outer circumference of the central opening field formed thereby.
- the chamber for merging which may have the screen body, is expediently wider.
- the junction or the sieve body is advantageously followed by an intermediate store for the liquid medium which is separate from the feed for the further medium and which has one or more relatively narrow supply openings in the region of its end remote from the sieve body, so that there is always an opening on the sieve body
- a larger quantity of liquid medium is present as a template, from which the sieve body can suck up by capillary action and from which the medium does not automatically flow back through the supply openings.
- the flow stabilization can be carried out in several stages in succession, e.g. in axially one behind the other, coaxial, same
- the annular chambers provided for the gaseous medium are connected to one another via continuously linear, parallel longitudinal channels, the width of which may be slightly larger and the number of which may be smaller than that of connecting channels which feed this medium directly to the merging or the sieve body.
- the respective channel or the respective chamber expediently has a substantially constant cross section over the entire length.
- the design according to the invention can ensure that the air enters the sieve chamber in a uniformly distributed manner with relatively low pressure and low speed. Furthermore, the pressure and the speed remain essentially constant even when the air is conveyed by a pump, such as a thrust piston pump. This enables a very fine-grained and homogeneous foam to be produced.
- the fine sieve body forms a sufficiently effective closure for the supply of liquid when not in use, since it is designed with regard to the flow properties or viscosity of the liquid medium in such a way that this medium does not flow through the sieve body under weight alone. This provides an effective leakage protection.
- Figure 1 shows a discharge head according to the invention in section.
- Fig. 2 shows a detail of Figure 1 in an enlarged view.
- Fig. 4 shows a cross section through a flow stabilization
- FIG. 5 shows a further embodiment in a representation corresponding to FIG. 2.
- the discharge head 1 is particularly suitable for use on a discharge device according to DE-OS 37 22 469, to which reference is made for further details and effects. It has a cap-shaped base body to be plugged onto the piston shaft of a fluid pump of the discharge device with a discharge nozzle 3 projecting approximately radially therefrom and forms a pressure handle with its cap end wall for pump actuation.
- the discharge nozzle 3, together with the base body 2, receives a foaming device 4 for separate feeding, intermediate storage, flow calming and subsequent merging with the formation of foam from a liquid medium and air.
- the discharge medium obtained emerges as a foam strand through an outlet opening 5 provided at the free end of the discharge nozzle 3.
- the base body 2 is connected to the one over the
- connection 6 Provide freely protruding, socket-shaped plug connection 6 on the inside of its cap end wall. This is surrounded in a ring by a plug connection 7, which lies within the cap jacket and projects in the same direction, for an air pump 8 (not shown in detail), the cylinder of which is formed by the cap jacket and the one on the housing of the liquid Pump fixedly arranged, penetrated by the piston skirt sealed annular piston.
- the connection 6 has an angled feed duct 9 leading to the rear end of the discharge nozzle 3.
- a supply duct 11 of the air connection 7, which surrounds the connection 6 in a ring shape, likewise leads within the base body 2 into this rear end. Between the supply ducts 9, 11 and the outlet opening 5, only straight-line or parallel or symmetrical flow paths with changing inner widths are provided.
- the discharge nozzle 3 is inserted as a self-contained assembly with its rear end in a corresponding flange area of the one-piece base body 2, at the connection 7 of which an outlet valve unit of the air pump 8 which is directly adjacent to the associated pump chamber can be fastened .
- the outlet nozzle 3 or the foaming device 4 consists of three sleeve parts inserted into one another, namely two inner sleeve parts 12, 13 and an outer sleeve 14 forming the outlet opening 5.
- the sleeve part 12 is used with a protruding over the rear end of the outer sleeve 14 and in Inside a core 15 receiving fastening end 16, which has two sections 17, 18 which are offset in diameter from one another, for plug-in or snap connection with the flange part of the base body 2.
- a subsequent, slightly expanded section 19 lies within one through the rear end of the outer sleeve
- REPLACEMENT LEAF 14 formed receiving sleeve 21, the constant inner circumference of which connects to an end channel via an annular shoulder.
- the section 19 merges over an approximately flat annular shoulder into an end section 20 which is substantially reduced in outer diameter and onto which the longer sleeve part 13 is attached.
- the sleeve part 12 and the sleeve part 13 can form an assembly module with a constant outer diameter in the region of the section 19 and the sleeve part 13 and can be inserted with tension into the receiving sleeve 21.
- longitudinal channels 22 are provided in the form of longitudinal grooves, which are distributed evenly over the circumference and extend beyond the front end of the core 15 and at the rear ends thereof the supply channel 9 via an annular gap connects.
- the interior thereof forms a continuously wide, elongated chamber 23.
- the air supply duct 11 adjoins the rear end of a chamber 24 which lies in front of the annular gap for the supply ducts 22 and surrounds this in a ring-shaped manner and which is delimited on its front end face by the rear end of the section 18 and on the inside circumference by the section 17.
- a ring of connecting channels 25 which are arranged uniformly about the central axis 10 and which extend as far as the front annular shoulder of the section 19 and are completely bore-like within the casing of the sleeve part 12.
- R SET SHEET connects a further, annular chamber 26, which in a corresponding manner is delimited on the one hand by the sections 19, 20 and on the other hand by the sleeve part 13, can be larger compared to the chamber 24 and also has approximately square cross sections.
- the front end wall of the chamber 25 is adjoined by a multiplicity of connecting channels 27, which are narrower and substantially shorter than the connecting channels 25 and arranged in a ring around the chamber 23.
- the connecting channels 27 are formed by longitudinal grooves on the inner circumference of the sleeve part 13 and delimited by the outer circumference of the end section 20 and, like the connecting channels 25, each have a constant width over their length. They extend to the bottom end wall 29 of a chamber provided as a junction 28 for the media; this end wall 29 is formed by the front end face of the sleeve part 12 and an inner ring surface lying in its plane of an enlarged inner section of the sleeve part 13.
- the described channel arrangement forms a flow calming 30 for the supplied air, which is located immediately before the junction 28 and which, like the liquid, is essentially only guided or enters and exits axially.
- the liquid is foamed with the air in such a way that the foam from the outlet 31 opposite on the face side enters an approximately constantly wide, elongated end channel 33, whose front end forms the outlet opening 5 and in which the foam can still stabilize completely.
- the slightly further end channel 33 compared to the chamber 23 is narrower than the chamber 32.
- the chamber 32 is essentially completely filled with a sieve unit 37, the fine-meshed or microporous sieves 38 of which are perpendicular to the direction of flow and to the central axis 10 in a uniform manner , stand small distances behind each other and which engage with their circumferential edges 39 tightly in the inner circumference 36 of the chamber 32.
- the inlet openings 34, 35 for liquid and air, which are located in a common plane and are formed by the ends of the chamber 23 and the connecting channels 27, are located radially apart within the inner circumference 36 directly adjacent to the end face of the first sieve 38 and essentially in the same Distances from these.
- These sieves 38 and the chamber 32 cause a further throttling and calming of the air flow, which penetrates the pores of the sieve with the entrainment of the liquid, so that foaming can begin or take place between adjacent sieves 38 and the resulting foam also due to the arising Volume increase is pressed by the other sieves 38.
- the foam is then compressed slightly in the area of the narrower outlet 31.
- the length of the chamber 32 can be less than its width, with four screens 38 being arranged one behind the other in the case shown.
- the chamber 32 can be supplied with further liquid from the chamber 23 at any time.
- the air outlet of the air pump 8 can be valve-free or via a valve that is not preloaded in the manner of a pressure relief valve with a freely movable valve body, so that the flow rate and the pressure of the conveyed air can be controlled essentially solely by the manually actuated actuating pressure .
- the air outlet of the pump can also be provided with a pressure relief valve. The same applies to
- an outlet valve of the liquid pump 23 is simultaneously used for refilling the chamber with the air feed.
- the chamber 23 also serves to calm the flow, so that both the air and the liquid are supplied to the junction 28 only at low pressure and low flow speed.
- the chambers 24a, 26a, 32a and the channels 25a, 27a are formed by two sleeve parts 12, 40 which engage with one another over the major part of their length.
- the connection channels 25a can be delimited on one long side by the outer circumference of the inner sleeve part 40 and on all other long sides by a groove in the inner circumference of the outer sleeve part 12a, as described with reference to the channels 27.
- the bottom of this groove forms the associated, radially outer boundary of the chamber 26a, the side flanks of which, like the chamber 24a, are formed by two opposing annular shoulders on the one hand of the sleeve part 40 and on the other hand of the sleeve part 12a.
- the annular shoulder of the outer sleeve part 12a lying further forward in the flow direction merges into a channel section which has approximately the same inner width as the inner circumference 36a and is constant from this annular shoulder to the outlet 31a.
- the front end of the sleeve part 40 engages in a rear part of this inner channel in such a way that only the connection
- the front end section 20a of the sleeve part 40 is reduced in outer diameter compared to the section adjoining the rear annular shoulder of the chamber 26a and is provided over the circumference with longitudinal webs 44 which engage in corresponding longitudinal grooves on the inner circumference of the inner channel by insertion.
- the longitudinal grooves 45 can end or be longer at the front end 29a of the sleeve part 40 or at the front ends of the webs 44 and thus approximately at the rear end of the chamber 32a, or can extend as far as the outlet 31a.
- the rear fastening end 16a of the sleeve part 40 but also the rear end 18a of the sleeve part 12a are each fixed in corresponding bores in the base body 2a by engagement or pressing. Only the rear fastening end 18a of the sleeve part 12a is axially secured with respect to the base body 2a by a snap connection, while the inner sleeve part 40 is secured against forward movements by the stop of its front end on the sleeve part 12a.
- the chamber 23a has a rear channel section 42 and a narrower, front channel section 43 which runs smoothly to the inlet opening 34a.
- the feed channels 22a form channel sections 41 in the area of the core 15a, which are delimited in a closed cross-section over the circumference.
- the bore receiving the core 15a extends with a constant inner width beyond the front end of the core 15a by an amount that is smaller than its width. Then this bore passes into the slightly widened section 42, which adjoins the rear end of the channel section 43 via an annular conical shoulder and is longer compared to its inner width.
- the channel section 43 which is longer in comparison, is narrower than the bore receiving the core 15a.
- the bottom surfaces of the grooves forming the channel sections 41 go continuously up to the conical annular shoulder, but the groove depth is correspondingly smaller due to the expansion of the channel section 42 in its area.
- the liquid can leave the inlet opening 34a as an enveloping stream which has been formed on the inner circumference of the channel section 43.
- the air also leaves the inlet openings 35a in a corresponding envelope stream formed from individual longitudinal streams.
- the front end 13a of the sleeve part 12a is reduced in its outer width and lies essentially without contact in a front bore section 47 of the outer sleeve 14a, which merges into the rear end of the end channel 33a via an inner annular shoulder.
- the bore section 47 merges via an annular shoulder into a slightly enlarged bore section 46, in which the further section of the sleeve part 12a engages tightly and with limited stops.
- the end channel 33 or 33a is used for the finished development and stabilization of the foam and is therefore smooth-walled and free from edges or abrupt changes in its width. 5, the end channel 33a is widened at an acute angle from the rear end to the outlet opening 5a, and its length is greater than its mean width. As a result, the foam has the possibility on the way through the end channel 33a to expand radially slightly and to assume an even finer structure. In the area of the outlet opening 5a, the front edge of the end channel 33a is convexly rounded in cross section, so that here too
- the feed channel 11a of the connection 7a is formed by a tubular connecting piece, onto which a valve housing of an outlet valve of the air pump can be snapped and can thereby be attached.
- this valve or the associated valve seat is located directly adjacent to the chamber 24a, into which the supply channel 11a opens radially.
- the sleeve parts 12a, 40 and the outer sleeve 14a can be put together in pairs or all to form pre-assembled assemblies.
- the sleeve part 40 can also be pre-assembled in front of the sleeve part 12a and the outer sleeve 14a on the base body 2a, after which the sleeve part 12a and the outer sleeve 14a can be assembled one after the other or as an assembly. This results in simple assembly.
