Description
Fremgangsmåde til bortsugning af pulver fra en spand og sugeagregat til udøvelse af fremgangsmåden.Process for suctioning powder from a bucket and suction unit for carrying out the process.
Opfindelsen vedrører en fremgangsmåde til bortsugning af pulver fra en spand, medens denne fyldes med pulver, idet der i nærheden af spandens rand anbringes et sugeaggregat.The invention relates to a method for extracting powder from a bucket while filling it with powder, whereby a suction unit is placed near the rim of the bucket.
En sådan fremgangsmåde anvendes fx i forbindelse med, at der skal røres pulver op med vand. Normalt kommes der først vand i en blandespand, hvorefter pulveret hældes i fx fra en pose. Uanset den foretrukne blandemetode vil pulveret slå op fra spanden, når det hældes i, og forurene luften til skade for de mennesker, som opholder sig i lokaletSuch a method is used, for example, in connection with the stirring of powder with water. Usually, water is first poured into a mixing bucket, after which the powder is poured into, for example, from a bag. Regardless of the preferred mixing method, the powder will blow up from the bucket as it is poured in and contaminate the air to the detriment of the people staying in the room
Man har forsøgt sig med at montere en simpel tragt i nærheden af spandens rand og forbinde tragten til en støvsuger. Dette er hensigtsmæssigt, fordi der i dag skal findes en støvsuger på enhver byggeplads, men de kendte tragte har ikke fungeret tilfredsstillende.Attempts have been made to mount a simple funnel near the bucket rim and connect the hopper to a vacuum cleaner. This is appropriate, because today a vacuum cleaner must be found at every construction site, but the known hoppers have not worked satisfactorily.
Alternativt har man forsøgt at tilsætte olie til pulveret for at dæmpe dets tendens til at sprede sig i lokalet, men selv om olien dæmper pulverets spredning, så vil den der står tæt på spanden nu indånde olieblandet pulver. Endvidere fordyrer det pulveret og skader miljøet.Alternatively, an attempt has been made to add oil to the powder to dampen its tendency to spread in the room, but even if the oil attenuates the spread of the powder, the one close to the bucket will now inhale oil-mixed powder. Furthermore, it impairs the powder and damages the environment.
Formålet med opfindelsen er, at angive en fremgangsmåde til at reducere spredning af pulver i lokalet i forhold til, hvad der har kunnet opnås ved den nævnte kendt teknik.The object of the invention is to provide a method for reducing the dispersion of powder in the room in relation to what has been achieved by said prior art.
Dette formål opnås ved, at sugeaggregatet anbringes således, at sugeaggregatet anbringes langs en del af spandens rand således, at der etableres en pulverfælde mellem sugeaggregatet og indersiden af spanden, og at pulveret hældes ned i spanden i retning mod den inderside af spanden, som er modstående i forhold til sugeaggregatet.This object is achieved by placing the suction assembly such that the suction assembly is positioned along a portion of the rim of the bucket such that a powder trap is established between the suction assembly and the inside of the bucket and the powder is poured into the bucket towards the inside of the bucket which is opposed to the suction unit.
Opfindelsen er baseret på den erkendelse, at hvis man hælder pulveret ned i spanden i retning mod et område af spandens inderside, så vil pulveret vende retning i spanden og slå op langs det diametralt modsatte område af spanden. Ved at anbringe sugeagregatet langs randen af netop dette modsatte område af spanden, og således tilvejebringe en pulverfælde på dette sted, vil det pulver, som slår op, blive fanget effektivt i pulverfælden. Det bemærkes, at det kunne opfattes som et nærliggende alternativ at lade sugeaggregatet strække sig rundt langs hele spandens periferi. Det vil imidlertid have den ulempe, at sugeaggregatet vil forsøge at indsuge også det pulver, som er på vej ned i spanden, hvorved der går for meget pulver til spilde, og sugeaggregatet bliver hurtigere belagt med pulver, som skal renses af. Endvidere ville der blive dårligere plads til et piskeris, specielt af den type, som kan monteres i forhold til spanden. Det ville blive vanskeliggjort, hvis sugeaggregatet strækker sig langs hele spandens periferien.The invention is based on the realization that if one pours the powder down into the bucket towards an area of the inside of the bucket, then the powder will face the bucket and look up along the diametrically opposite area of the bucket. By positioning the suction assembly along the edge of just this opposite area of the bucket, thus providing a powder trap at this location, the powder which is blowing up will be effectively trapped in the powder trap. It should be noted that it could be seen as a nearby alternative to allow the suction unit to extend around the entire bucket periphery. However, it will have the disadvantage that the suction unit will try to suck in also the powder that is going down into the bucket, which will waste too much powder and the suction unit will be coated more quickly with powder to be cleaned. Furthermore, there would be less room for a whip, especially of the type that can be mounted in relation to the bucket. It would be difficult if the suction unit extends along the entire bucket periphery.
Ved netop kun at lade sugeaggregatet strække sig langs en del af spandens periferi og at etablere en pulverfælde opnås en optimal kombination af simpel konstruktion, effektiv bortsugning - overvejende af den del af pulveret, som slår op, og at sugeaggregatet er let og hensigtsmæssigt at arbejde med i praksis.By just allowing the suction unit to extend along a portion of the bucket's periphery and establishing a powder trap, an optimal combination of simple construction, efficient suctioning is achieved - predominantly by the part of the powder that opens up, and the suction unit is easy and convenient to work with in practice.
Spandens rand kan have en hvilken som helt form, men er typisk cirkelrund. Fortrinsvist anbringes sugeaggregatet langs i hovedsagen halvdelen af spandens periferi. Det kan være således, at det er lidt mindre end den halve periferi, således at det ikke kolliderer med et par modstående hankområder, eller således at sugeaggregatet er lidt større, hvis hankområderne findes under randen.The rim of the bucket may have any shape, but is typically circular. Preferably, the suction assembly is disposed along substantially half of the bucket periphery. It may be that it is slightly smaller than half the periphery so that it does not collide with a couple of opposite hinge areas, or so that the suction unit is slightly larger if the hinge areas are below the rim.
Udsugningen tilvejebringes på i og for sig kendt måde ved hjælp afen støvsuger, som fortrinsvis er koblet til sugeaggregatet, men som også kunne være integreret med sugeaggregatet. Udsugningen vil i det mindste findes i nærheden af pulverfælden, som vil reducere pulverets hastighed væsentligt, således at det kan fanges, selv om der ikke suges direkte fra pulverfælden. Ved den foretrukne udførelsesform vil der blive suget fra selve pulverfælden, hvorved man udnytter det vacuum, som opstår i pulverfætden, men ved en foretrukken udførelsesform suges der tillige også uden for pulverfælden for at opfange det pulver, som kan være slået op uden for pulverfælden.The suction is provided in a manner known per se by means of a vacuum cleaner, which is preferably coupled to the suction unit but which could also be integrated with the suction unit. The extraction will at least be found in the vicinity of the powder trap which will substantially reduce the speed of the powder so that it can be trapped, even if it is not sucked directly from the powder trap. In the preferred embodiment, suction will be drawn from the powder trap itself, utilizing the vacuum created in the powder sump, but in a preferred embodiment, suction outside the powder trap will also be sucked to capture the powder which may be blown up outside the powder trap.
Ovenfor har forklaringen af opfindelsen koncentreret sig om at fange det pulver, som slår op i rummet, når pulveret hældes ned i spanden fra en vis højde. Det kan imidlertid ikke undgås, at der også er risiko for, at der slynges pulver op af spanden, når pulver og væske blandes, typisk med et motordrevet piskeris, som på i og for sig kendt måde midlertidigt er monteret på spanden. Derfor tilvejebringes der typisk et sugerør, som udmunder uden for pulverfælden således, at sugerøret suger i samme retning, som pulveret roterer under blandingen. Sugerørets yderste ende, som bestemmer sugeretningen er med fordel drejet en smule skråt nedad for at modvirke, at der indsuges falsk luft. Tilsvarende kan den roterende bevægelse af luft og pulver påvirkes i nedadgående retning ved hjælp afen ledeplade, som typisk anbringes i den ende af sugeaggregatet, som er modsat udmundingen af sidstnævnte sugerør.Above, the explanation of the invention has been concentrated on capturing the powder that rises in the room when the powder is poured into the bucket from a certain height. However, it cannot be avoided that there is also a risk of powder being thrown up by the bucket when the powder and liquid are mixed, typically with a motor-driven whisk which is temporarily mounted on the bucket in a manner known per se. Therefore, a suction tube is typically provided which opens outside the powder trap so that the suction tube sucks in the same direction as the powder rotates during mixing. The outermost end of the suction tube, which determines the suction direction, is advantageously turned slightly downwardly to prevent the intake of false air. Similarly, the rotary movement of air and powder can be affected in a downward direction by a baffle, which is typically positioned at the end of the suction assembly opposite to the outlet of the latter suction pipe.
Når der suges fra pulverfælden, vil dette fordelagtigt foregå ved hjælp af et sugerør, som også suger i samme retning, som pulveret roterer under opblandingen. Det indvendige tværsnitsareal for de nævnte sugerør tilpasses i afhængighed af sugerørenes længde og den ønskede fordeling af sugestyrken.Advantageously, when sucked from the powder trap, this will be done by means of a suction tube which also sucks in the same direction as the powder rotates during mixing. The internal cross-sectional area of the said suction pipes is adjusted depending on the length of the suction pipes and the desired distribution of the suction strength.
Opfindelsen vedrører også et sugeaggregat til udøvelse af fremgangsmåden ifølge opfindelsen. Sugeaggregatet er ejendommeligt ved, at det er formgivet til at modsvare en del af spandens overkant, som det er indrettet til at kunne anbringes udløseligt på, og ved, at sugeaggregatet har et skørt, som, når sugeaggregatet er anbragt i brugsstillingen, strækker sig et stykke ned mod spandens bund i afstand fra spandens inderside således, at der defineres en pulverfælde mellem skørtet og spandens inderside, og at sugeaggregatet har mindst én sugeåbning i nærheden pulverfælden.The invention also relates to a suction assembly for carrying out the method according to the invention. The suction unit is peculiar in that it is designed to correspond to a portion of the upper edge of the bucket on which it is arranged to be releasably mounted, and in that the suction unit has a skirt which, when the suction unit is placed in the operating position, extends a down towards the bottom of the bucket at a distance from the inside of the bucket such that a powder trap is defined between the skirt and the inside of the bucket and that the suction unit has at least one suction opening in the vicinity of the powder trap.
Et afgørende træk ved opfindelsen er tilvejebringelsen af mindst én pulverfælde, som både fanger pulveret, men også reducerer dets hastighed. Derfor vil der kunne opnås mange muligheder for at opfange pulveret effektivt i, omkring eller helt uden for en pulverfælde.A crucial feature of the invention is the provision of at least one powder trap which both captures the powder but also reduces its speed. Therefore, many opportunities can be obtained to capture the powder effectively in, around or completely outside a powder trap.
Ved at tilvejebringe flere skørter, kan der også defineres flere pulverfælder, fx i forbindelse med store spande, men ved en foretrukken og meget enkel udførelsesform er pulverfælden defineret mellem et enkelt skørt og spandens inderside. Et dyrere, men også mere alsidigt sugeagregat kan opnås ved hjælp af flere skørter med uens radius, således, at sugeaggregatet kan anvendes på forskellige størrelser spande.By providing multiple skirts, multiple powder traps can also be defined, for example, in connection with large buckets, but in a preferred and very simple embodiment, the powder trap is defined between a single skirt and the inside of the bucket. A more expensive, but also more versatile suction unit can be obtained by means of several skirts of different radii, so that the suction unit can be used on different sizes of buckets.
En anden mulighed for at kunne tilpasse sugeaggregatet til flere størrelser spande er, at gøre det deformerbart, men selv om der findes mange variationsmuligheder, så vil opfindelsen med særlig fordel kunne anvendes i forbindelse med produkter, hvor prisen skal være lav. Netop til denne anvendelse vil opfindelsen i sin mest simple udførelsesform være et væsentligt fremskridt i en standardstørrelse, hvor pulveret leveres i en blandespand, og sugeaggregatet leveres med.Another possibility of being able to adapt the suction unit to several sizes of buckets is to make it deformable, but although there are many variation options, the invention will be particularly advantageous for products where the price must be low. Precisely for this application, the invention, in its most simple embodiment, will be a significant step forward in a standard size in which the powder is supplied in a mixing bucket and the suction unit is supplied.
Ved en foretrukken udførelsesform omfatter sugeaggregatet et første og et andet sugerør, som er forbundet sammen til en koblingsstuds, der er dimensioneret til at kunne sammenkobles med en støvsugerslange. Det første sugerør udmunder i pulverfælden i nærheden af den ene ende af sugeaggregatet, medens det andet sugerør udmunder uden for pulverfælden i nærheden af den modstående ende af sugeaggregatets ender. Denne placering medfører optimal bortsugning af pulver i forbindelse med, at pulveret opblandes og roterer i en foretrukken retning, som er bestemt af et håndværktøj eller et midlertidigt anbragt piskeris.In a preferred embodiment, the suction assembly comprises a first and a second suction pipe, which are connected together to a coupling plug which is dimensioned to be coupled to a vacuum cleaner hose. The first suction tube opens in the powder trap near one end of the suction unit, while the second suction tube opens outside the powder trap near the opposite end of the suction unit ends. This location results in optimal powder extraction as the powder is mixed and rotated in a preferred direction determined by a hand tool or a temporary whisk.
Ved en udførelsesform kan der i nærheden af den ende af sugeaggregatet, hvor den første sugeåbning udmunder, være anbragt en ledeplade, som i brugsstillingen er tværstillet i forhold til en hosliggende side af spanden således, at en roterende luft/pulver bevægelse påvirkes i retning skråt nedad mod spandens bund. Denne luftbevægelse vil vende til en skråt opadgående bevægelse, og ved den foretrukne udførelsesform er det andet sugerør, som fortrinsvist er diametralt beliggende i forhold til en eventuel ledeplade, rettet skråt nedad for bedre at fange det skråt opad kommende pulver. Ved denne retning for det andet sugerør vender dette således skråt nedad mod spandens bund, hvorved det modvirkes, at der suges falsk, dvs pulverfattig luft ind.In one embodiment, near the end of the suction unit where the first suction opening opens, a baffle plate which is transversely positioned relative to an adjacent side of the bucket may be arranged so that a rotating air / powder movement is affected in an inclined direction. down towards the bottom of the bucket. This air movement will reverse an oblique upward movement, and in the preferred embodiment, the second suction tube, which is preferably diametrically positioned relative to any bias plate, is directed obliquely downward to better capture the obliquely upward powder. Thus, in this direction of the second suction pipe, this faces obliquely downwards towards the bottom of the bucket, thereby counteracting that false, ie powder-poor air is sucked in.
Opfindelsen vil blive nærmere forklaret ved hjælp af den følgende beskrivelse afen udførelsesform, idet der henvises til tegningen, hvorThe invention will be explained in greater detail by means of the following description of an embodiment, with reference to the drawing, in which
Fig 1 viser en spand med en udførelsesform for sugeaggregatet ifølge opfindelsen,Fig. 1 shows a bucket with an embodiment of the suction unit according to the invention,
Fig 2 A og B viser et snit II-1I gennem det, der er vist på fig 1, medens Fig 3 perspektivisk viser sugeaggregatet fra fig 1, set nedefra.Figures 2A and B show a section II-1I through what is shown in Figure 1, while Fig. 3 is a perspective view from below of the suction assembly of Figure 1.
Fig 1 viser en spand 1, på hvilken der er anbragt en udførelsesform for sugeaggregatet 2 ifølge opfindelsen. Spanden kan typisk have tjent som emballage for et pulver fx på cementbasis, som skal opblandes med vand, før det anvendes, idet spanden så anvendes som blandespand. Da der først skal hældes vand i spanden, benytter man en tom spand, og derefter hældes pulveret i, hvorved der som tidligere beskrevet slynges pulver ud i lokalet til skade for de mennesker, som befinder sig i nærheden. Opfindelsen løser dette problem fx ved hjælp af den på fig 1 viste udførelsesform 2.Fig. 1 shows a bucket 1 on which an embodiment of the suction unit 2 according to the invention is arranged. Typically, the bucket may have served as packaging for a powder, for example, on a cement basis, which must be mixed with water before use, the bucket being then used as a mixing bucket. Since water must first be poured into the bucket, an empty bucket is used, and then the powder is poured in, which, as previously described, throws powder into the room to the detriment of the people who are nearby. The invention solves this problem, for example by means of the embodiment 2 shown in Fig. 1.
Sugeaggregatet 2 strækker sig i brugsstillingen fortrinsvist rundt langs ca. halvdelen af spandens periferi, således at det kan presses udløseligt fast på spandens rand uden at kollidere med eventuelle hankfremspring 3,4. Som vist på figuren strækker sugeaggregatet sig et lille radialt stykke ind over spandens åbning, idet det omfatter en overside 5 og et rundtgående, skråt nedadvendende skørt 6. På fig 1 ses endvidere en sugeåbning 10 og en studs 7, der er indrettet til at kunne sammenkobles med en støvsugerslange.The suction unit 2 extends in the position of use preferably around approx. half of the bucket periphery so that it can be releasably pressed firmly on the rim of the bucket without colliding with any hand projections 3.4. As shown in the figure, the suction assembly extends a small radial portion over the opening of the bucket, comprising an upper side 5 and a circumferential, inclined downward skirt 6. In Figure 1, there is also seen a suction opening 10 and a stud 7 arranged to be able to is connected to a vacuum hose.
På fig 2 A er det skematisk illustreret, hvorledes pulveret slår op af spanden, når det hældes ned i blandingen af vand og pulver. Pilen PI illustrerer pulverets vej ned i spanden, medens P2 illustrerer, hvorledes en overvejende del af det pulver, som ellers ville sprede sig i lokalet fanges afen pulverfælde ifølge opfindelsen, som er defineret mellem spandens inderside, sugeaggregatets overside 5 og skørtet 6.Figure 2A illustrates schematically how the powder beats up the bucket as it is poured into the mixture of water and powder. The arrow P1 illustrates the path of the powder into the bucket, while P2 illustrates how a predominant portion of the powder that would otherwise disperse in the room is trapped by a powder trap according to the invention defined between the inside of the bucket, the top of the suction unit 5 and the skirt 6.
På fig 2B ses snittet mere detaljeret, hvor der kan ses et første sugerør 8 og i snit et andet sugerør 9. Pulverfælden er ved den viste udførelsesform lukket opadtil overvejende af sugerøret 9, som strækker sig over det meste af sugeaggregatets perifere længde, men er til dels også lukket af oversiden 5. Det væsentlige for opfindelsen er etableringen af pulverfælden, som ved den viste udførelseform defineres af skørtet 6. Sugerøret 8 udmunder i nærheden af sugeaggregatets første ende, hvor studsen 7, som det er forbundet med, findes. Dette betyder, at det pulver, som er fanget i pulverfælden, bortsuges i nærheden af aggregatets nævnte, første ende, hvilket har relation selve blandeprocessen.In Fig. 2B, the section is seen in more detail, where a first suction tube 8 and in section a second suction tube 9 can be seen. In the illustrated embodiment, the powder trap is closed upwardly predominantly by the suction tube 9, which extends over most of the peripheral length of the suction unit, but is partly closed by the upper side 5. Essential to the invention is the establishment of the powder trap, which in the illustrated embodiment is defined by the skirt 6. The suction pipe 8 opens in the vicinity of the first end of the suction unit, where the plug 7 with which it is connected is found. This means that the powder trapped in the powder trap is aspirated near the first end of the assembly, which relates to the mixing process itself.
Pulveret blandes typisk vha af et eldrevet piskeris, således at der opstår en relativt kraftig rotation af luft/pulver blanding, som også vil søge op og ud af spanden. Derfor suges der fra den ende af pulverfælden, hvor pulveret har opholdt sig i længst tid. Pulverfælden reducerer hastigheden af luft/pulver blandingen, og sugerøret 8 medfører et vacuum i pulverfælden.The powder is typically blended using an electric whisk, resulting in a relatively strong rotation of air / powder mixture, which will also seek up and out of the bucket. Therefore, it is sucked from the end of the powder trap where the powder has stayed for the longest time. The powder trap reduces the speed of the air / powder mixture and the suction tube 8 causes a vacuum in the powder trap.
Ifølge opfindelsen er det hverken nødvendigt eller hensigtsmæssigt, at sugeaggregatet strækker sig rundt langs hele spandens periferi med de ulemper, som blev nævnt indledningsvist, til følge. Til gengæld er det hensigtsmæssigt, at sugeaggregatet også har en sugeåbning 10 uden for pulverfælden. Dette vil fremgå nærmere af den følgende forklaring nedenfor affig3.According to the invention, it is neither necessary nor appropriate for the suction unit to extend around the entire periphery of the bucket, with the disadvantages mentioned at the outset. On the other hand, it is desirable that the suction unit also has a suction opening 10 outside the powder trap. This will be further explained in the following explanation below affig3.
På fig 3 ses den foretrukne udførelsesform perspektivisk nedefra. Der er vist en rundtgående flange 11 [se også fig 2B), der er indrettet til at ligge an mod spandens yderste rand, idet sugeaggregatet er fasthodt udløseligt mellem en afstandsflange 12 og eftergivelige fremspring 13 - 16, som strækker sig ind under spandens rand.In Figure 3, the preferred embodiment is shown from below in perspective. There is shown a circumferential flange 11 [see also Fig. 2B) arranged to abut against the outer edge of the bucket, the suction assembly being fixed releasably between a spacer flange 12 and resilient projections 13-16 extending into the rim of the bucket.
Fig 3 viser også sugerøret 9, som i den ene ende er forbundet med sugerøret 8 og med studsen 7, som er skjult på fig 3. Det bemærkes, at sugerøret 9 slår et knæk (ved 17], hvorved sugeretningen bliver skråt nedefra. Dette betyder, at der suges mindre falsk luft ind ved spandens rand. På denne måde kan en stor del af det pulver, som ellers ville rotere uden for pulverfælden, også blive fanget af sugeaggregatet ifølge opfindelse.Fig. 3 also shows the suction tube 9, which is connected at one end to the suction tube 8 and to the plug 7, which is hidden in Fig. 3. It is noted that the suction tube 9 beats (at 17], thereby causing the suction direction to be inclined from below. This means that less false air is sucked in at the rim of the bucket, so that a large part of the powder that would otherwise rotate outside the powder trap can also be trapped by the suction unit according to the invention.
