Definitions
- the invention relates to a method and a device for mixing suspensions containing solids, in which a suspension containing solids is introduced in a pressure-tight and solid container which is closed on all sides and is atomized by means of a pressure spray system from a nozzle and applied to a surface, the pressure spray system being from the outside is pressurized.
- the purpose of such inventions is to avoid sedimentation of solid matter components from suspension mixtures in the bottom region of the containers or to integrate sedimentation constituents homogeneously into the suspension again and to make them accessible to the spray system without blocking the latter.
- the object of the invention is now, while avoiding the aforementioned disadvantages, to create a reusable spray system with a safe mixing of the separated solid body components with the suspension liquid and a safe application of the suspension mixture from the spray container without further manipulations.
- This solution has the advantage that the suspension is constantly mixed during each pumping process and during the spraying process, so that a loss of function due to clogging of the spraying system is avoided, and that this spraying system is used in refillable, propellant-free spray containers.
- Another advantage is that retrofitting of spray systems of the type mentioned at the beginning is made possible by means of a separately usable part.
- Fig. 1 normal air (15) is introduced manually through holes (22) in the pump casing (2) into the pressure-tight and -proof container housing (10) via the pump piston (1). This is done by the air first penetrating into the cavity (11) formed by the union sleeve (4); spreads there in all directions and is prevented from spreading further in the upper area by the valve (8).
- the union sleeve (4) is non-positively and / or positively connected to a tulip (9) of the container housing (10), but here has slots (19) which serve to penetrate the air.
- the pump piston is locked on the lower container part (26) - not shown here - and the suspension mixture (16) is discharged via the valve (8).
- the reverse process is carried out as described above, in that the air from the upper container part (23) presses on the suspension mixture (16).
- the suspension mixture (16) now mixed by the pumping process flows through the slots (19) into the cavity (11) between the union sleeve (4) and the pump envelope (2) and further up to the sieve insert (6).
- There a metering mixing is carried out in the conically tapering outlet area (18) so that there is an absolutely uniform distribution of the solid body components (14) in front of the spray neck (7) of the valve (8).
- the air (15) escapes and entrains the suspension mixture (16).
- the suspension mixture (16) is uniformly applied and thus applied to the corresponding surface.
Abstract
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Durchmischung feststoffhaltiger Suspensionen, bei denen eine feststoffhaltige Suspension in einem allseits geschlossenen, druckdichten und -festen Behälter eingebracht ist und mittels eines Drucksprühsystems aus einer Düse zerstäubt und auf eine Oberfläche aufgebracht wird, wobei das Drucksprühsystem von außen mit Druck beaufschlagt ist, indem der den Kolben (1) umschließende Pumpenhüllraum (2) von einer im unteren Bodenbereich (3) luftdurchlässigen übwerwurfhülse (4) übergriffen wird, die in Ventilrichtung (5) einen Siebeinsatz (6) zeigt und die sich konisch verjüngend den Sprühhals (7) des Ventils (8) umgreifend erstreckt, und die eingepumpte Luft (15) von der Überwurfhülse (4) in den Bodenbereich (3) des SprühBehälters (10) gelenkt, dort die abgesetzten Feststoffkörperbestandteile (14) aufwirbelnd durchdringt und sich im Sprühbehälteroberteil (23) unter Druckaufbau sammelt, sodann die sich im Sprühbehälteroberteil (23) befindliche Luft bei Betätigung des Ventils (8) das aufgewirbelte Suspensionsgemisch (16) durch den zylinderförmigen Hohlraum (11) dem Ventil (8) zuführt, wobei durch den Siebeinsatz (6) eine gleichmäßige Suspensionszuführung in den konischen Wirkstoffmischer (17) erfolgt, so daß ein gleichmäßig verteiltes Gemisch aus der Ventildüse (18) austritt.The invention relates to a device and a method for mixing suspensions containing solids, in which a suspension containing solids is introduced in a pressure-tight and solid container which is closed on all sides and is atomized by means of a pressure spray system from a nozzle and applied to a surface, the pressure spray system being from the outside is pressurized by the pump envelope (2) enclosing the piston (1) being overlapped by a throwing sleeve (4) which is air-permeable in the lower base region (3) and which shows a strainer insert (6) in the valve direction (5) and which tapers conically extends around the spray neck (7) of the valve (8), and the pumped-in air (15) is directed from the union sleeve (4) into the bottom region (3) of the spray container (10), where it swirls through the separated solid body components (14) and penetrates itself in the upper part of the spray container (23) under pressure build-up, then in the upper part of the spray container (23) Sensitive air when the valve (8) is actuated feeds the whirled up suspension mixture (16) through the cylindrical cavity (11) to the valve (8), with a uniform suspension supply into the conical active ingredient mixer (17) through the sieve insert (6), so that an evenly distributed mixture emerges from the valve nozzle (18).
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Durchmischung feststoffhaltiger Suspensionen, bei denen eine feststoffhaltige Suspension in einem allseits geschlossenen, druckdichten und -festen Behälter eingebracht ist und mittels eines Drucksprühsystems aus einer Düse zerstäubt und auf eine Oberfläche aufgebracht wird, wobei das Drucksprühsystem von außen mit Druck beaufschlagt ist.The invention relates to a method and a device for mixing suspensions containing solids, in which a suspension containing solids is introduced in a pressure-tight and solid container which is closed on all sides and is atomized by means of a pressure spray system from a nozzle and applied to a surface, the pressure spray system being from the outside is pressurized.
Derartige Erfindungen haben den Zweck, das Absetzen von Feststoffkörperbestandteilen aus Suspensionsgemischen im Bodenbereich der Behälter zu vermeiden oder abgesetzte Bestandteile wieder homogen in die Suspension zu integrieren und dem Sprühsystem zugänglich zu machen, ohne letztere zu blockieren.The purpose of such inventions is to avoid sedimentation of solid matter components from suspension mixtures in the bottom region of the containers or to integrate sedimentation constituents homogeneously into the suspension again and to make them accessible to the spray system without blocking the latter.
So ist es bekannt, die einzelnen Bestandteile einer Suspension durch intensives Schütteln des Behälters wieder miteinander zu vermischen oder Kugeln in den Behälter einzubringen, die die abgesetzten Feststoffkörperbestandteile durch Verwirbelung der Suspension wieder zugänglich machen.It is known, for example, to mix the individual constituents of a suspension together again by shaking the container intensively or to introduce balls into the container which make the sedimented solid constituents accessible again by swirling the suspension.
Hierbei ist es nachteilig, daß bei ungenügendem Aufschütteln Verklumpungen in der Suspension verbleiben, die ein Verstopfen des gesamten Ventilsystems hervorrufen. Diese Verstopfung des Ventilsystems durch Verklumpungen von Feststoffkörperbestandteilen, die in das Ventilsystem einmal eingedrungen sind, können nachträglich nicht mehr freigesprüht werden. Hervorgerufen wird dies, indem diese Feststoffkörperbestandteile sich im bekannten Steigrohr festsetzen und damit das gesamte System blockieren. Ein weiterer Nachteil der bekannten Systeme besteht darin, daß am Behälterboden keine große Fläche vorhanden ist, um beim Aufschütteln ein möglichst schnelles Verteilen der Feststoffkörperbestandteile zu erreichen.It is disadvantageous here that, if the shaking is inadequate, lumps remain in the suspension, which cause the entire valve system to become blocked. This blockage of the valve system due to the clumping of solid body components that have once penetrated into the valve system can no longer be sprayed free. This is caused by the fact that these solid matter components get stuck in the known riser pipe and thus block the entire system. Another disadvantage of the known systems is that on The bottom of the container does not have a large area in order to distribute the solid body components as quickly as possible when shaken.
Aufgabe der Erfindung ist es nun, unter Vermeidung der vorgenannten Nachteile, ein immer wieder verwendbares Sprühsystem mit einer sicheren Vermischung der abgesetzten Feststoffkörperbestandteile mit der Suspensionsflüssigkeit und ein sicheres Ausbringen des Suspensionsgemisches aus dem Sprühbehälter ohne weitere Manipulationen zu schaffen.The object of the invention is now, while avoiding the aforementioned disadvantages, to create a reusable spray system with a safe mixing of the separated solid body components with the suspension liquid and a safe application of the suspension mixture from the spray container without further manipulations.
Diese Aufgabe wird gemäß dem kennzeichnenden Teil der Ansprüche 1 und 11 gelöst.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen dargelegt.This object is achieved in accordance with the characterizing part of
Advantageous refinements are set out in the subclaims.
Diese Lösung hat den Vorteil, daß die Suspension bei jedem Pumpvorgang und während des Sprühvorgangs ständig durchmischt wird, so das ein Funktionsverlust durch Verstopfen des Sprühsystems vermieden wird, und daß dieses Sprühsystem in nachfüllbaren, treibgaslosen Sprühbehältern Einsatz findet. Ein weiterer Vorteil liegt darin, daß das Nachrüsten von im Markt befindlichen Sprühsystemen der eingangs genannten Art mittels eines separat verwendbaren Teils ermöglicht wird.This solution has the advantage that the suspension is constantly mixed during each pumping process and during the spraying process, so that a loss of function due to clogging of the spraying system is avoided, and that this spraying system is used in refillable, propellant-free spray containers. Another advantage is that retrofitting of spray systems of the type mentioned at the beginning is made possible by means of a separately usable part.
Die Erfindung wird nachstehend beschrieben und soll durch die Zeichnungen verdeutlicht werden.The invention is described below and is intended to be illustrated by the drawings.
Es zeigen:
- Fig. 1: einen Drucksprühbehälter im Schnitt, bei dem mittels einer Luftpumpe ein Druckmedium eingebracht wird,
- Fig. 2: einen DrucksprühBehälter im Schnitt, bei dem über ein Sprühventil das Suspensionsgemisch ausgebracht wird.
- 1: a pressure spray container in section, in which a pressure medium is introduced by means of an air pump,
- Fig. 2: a pressure spray container in section, in which the suspension mixture via a spray valve is applied.
Nach Fig. 1 wird über den Pumpenkolben (1) manuell normale Luft (15) durch Löcher (22) im Pumpenhüllraum (2) in das druckdichte und -feste Behältergehäuse (10) eingebracht. Dies geschieht, indem die Luft zunächst in den von der Überwurfhülse (4) gebildeten Hohlraum (11) dringt; sich dort in alle Richtungen ausbreitet und im oberen Bereich vom Ventil (8) an seiner weiteren Ausbreitung gehindert wird. Im unteren Bodenbereich (3) ist die Überwurfhülse (4) kraft- und/oder formschlüssig mit einer Auftulpung (9) des Behältergehäuses (10) verbunden, weist jedoch hier Schlitze (19) auf, die dem Durchdringen der Luft dienen.According to Fig. 1, normal air (15) is introduced manually through holes (22) in the pump casing (2) into the pressure-tight and -proof container housing (10) via the pump piston (1). This is done by the air first penetrating into the cavity (11) formed by the union sleeve (4); spreads there in all directions and is prevented from spreading further in the upper area by the valve (8). In the lower floor area (3), the union sleeve (4) is non-positively and / or positively connected to a tulip (9) of the container housing (10), but here has slots (19) which serve to penetrate the air.
Die Luft durchströmt die Schlitze (19) und verwirbelt beim Aufsteigen in das Behälteroberteil (23) die Ablagerungen (24) der Feststoffkörperbestandteile (14) aus dem Suspensionsgemisch (16) und verteilt diese Feststoffkörperbestandteile (14) gleichmäßig auf das gesamte Suspensionsvolumen. Letzteres geschieht solange, wie der Pumpvorgang vorhält und wird mit jedem Aufpumpen wiederholt.The air flows through the slots (19) and swirls the deposits (24) of the solid body components (14) from the suspension mixture (16) when it rises into the upper container part (23) and distributes these solid body components (14) evenly over the entire suspension volume. The latter happens as long as the pumping process continues and is repeated with each inflation.
Ist der entsprechende Druck im Behältergehäuse (10) aufgebaut, so wird der Pumpenkolben am Behälterunterteil (26) verriegelt - hier nicht dargestellt - und das Suspensionsgemisch (16) über das Ventil (8) ausgebracht.If the corresponding pressure is built up in the container housing (10), the pump piston is locked on the lower container part (26) - not shown here - and the suspension mixture (16) is discharged via the valve (8).
In Fig. 2 ist der folgende Ablauf dargestellt.The following sequence is shown in FIG. 2.
Hierbei erfolgt der umgekehrte Weg wie vorbeschrieben, indem die Luft aus dem Behälteroberteil (23) auf das Suspensionsgemisch (16) drückt.
Das nunmehr durch den Pumpvorgang durchmischte Suspensionsgemisch (16) strömt durch die Schlitze (19) in den Hohlraum (11) zwischen der Überwurfhülse (4) und dem Pumpenhüllraum (2) und weiter bis zum Siebeinsatz (6). Dort wird eine dosierende Vermischung in den konisch sich verjüngenden Auslaßbereich (18) vorgenommen, so daß eine absolut gleichmäßige Verteilung der Feststoffkörperbestandteile (14) vor dem Sprühhals (7) des Ventils (8) vorliegt. Durch Drücken des Ventils (8) entweicht die Luft (15) und reißt das Suspensionsgemisch (16) mit. Es erfolgt ein gleichmäßiges Ausbringen und damit Aufbringen des Suspensionsgemisches (16) auf die entsprechende Oberfläche.The reverse process is carried out as described above, in that the air from the upper container part (23) presses on the suspension mixture (16).
The suspension mixture (16) now mixed by the pumping process flows through the slots (19) into the cavity (11) between the union sleeve (4) and the pump envelope (2) and further up to the sieve insert (6). There a metering mixing is carried out in the conically tapering outlet area (18) so that there is an absolutely uniform distribution of the solid body components (14) in front of the spray neck (7) of the valve (8). By pressing the valve (8), the air (15) escapes and entrains the suspension mixture (16). The suspension mixture (16) is uniformly applied and thus applied to the corresponding surface.
