Definitions
- the invention relates to a device for continuously mixing a bulk material, in particular building materials or fertilizers, with a liquid and for continuously metering the mixture, with a storage and loading silos for the bulk material having an outlet opening at the bottom, with a mixing device having a mixing chamber which is below the The outlet opening of the silo is arranged and which has an inlet for the bulk material at the top and an outlet for the mixture at the bottom, the inlet being connected to the outlet opening of the silo, with a mixer shaft in the mixing device having at least one mixing tool, with a drive motor for the mixer shaft , with at least one feed device for a liquid in the area of the mixing tool and with a feed pump for the mixture connected to the outlet of the mixing device.
- Such a device is already known from DE-A-23 40 246.
- This device is arranged sloping under the storage and loading silo. Therefore, a transfer piece from the silo to the mixing device and its entry is required, which creates a cross-sectional reduction between the outlet opening of the silo and the mixing device.
- the outlet cross section of the outlet opening of the silo can therefore not be fully utilized in a disadvantageous manner.
- an inclined arrangement of the mixing device especially in the case of bulk materials which have components which tend to separate, there is a risk of separation because force components which are directed differently over the course of the inclined mixing device constantly attack the individual components of the mixture.
- bearings and the mixing tools are subjected to greater loads on one side due to the oblique arrangement, which can lead to unfavorable signs of wear.
- a comparable device for mixing is already known from DE-A-29 03 373, which is arranged essentially horizontally or - for filling containers with higher edges - rising obliquely. However, it is accepted that the bulk material first emerges vertically from the silo and must be deflected.
- a deflection of the bulk material in a horizontal or a sloping direction of conveyance is especially with poorly flowing material or with such material that tends to segregate because it consists of mixture components of different densities and / or grain size, or with bulk materials that tend to compress, unfavorable, since corresponding deviations, especially the mixing ratios, have to be expected in the resulting product. Accordingly, aggregates and above all high-quality binders have so far been mixed in a corresponding excess, so that the minimum strength of the end product is achieved even in the case of demixing and under other unfavorable mixing conditions.
- DE-C-463 559 already discloses a mixing machine, in particular for mortar, which is loaded from above. However, it is a matter of first producing the entire mixture from dry constituents and then mixing it with water. It is therefore provided in this previously known device that the individual substances to be mixed are fed from individual containers through individual hoppers to the mixing device. The individual funnels are located on the upper side of the mixing machine, so that there can be no possibility for arranging a storage and loading silo.
- the invention is based on the object of DE-A-23 40 246 to provide a device of the type mentioned, in which a risk of segregation can be largely avoided or such a risk of segregation can be counteracted, so that in particular high-quality binders in one Mixture in a reduced amount are required and damage to structures and the like can be avoided later.
- the product should be as homogeneous as possible and the wear of the individual parts of the device, in particular the associated feed pump, should be reduced to a minimum.
- the solution to this problem is that the mixer shaft is arranged vertically, that a premixing chamber for the bulk material is arranged in the mixing device above the mixing chamber, that the premixing chamber has at least one premixing tool and that the cross section of the premixing chamber corresponds to that of the outlet opening.
- the vertical arrangement eliminates one-sided loads on the mixing tools, the metering device and their bearings, so that the wear is reduced or at least evened out, so that individual parts are not worn out prematurely.
- the arrangement according to the invention allows the outlet cross section of the silo to be fully utilized because the device is arranged directly below the outlet opening and is adapted to its cross section. Gravity can make the transition from the storage and loading silo into the device provide the best possible support because the direction of conveyance is not redirected. This also at least reduces the risk of segregation, and any segregation can be counteracted with the premixing chamber and the premixing tool arranged therein. In practice, the bulk material can be mixed again in this premixer before it is then brought into contact with the mixing liquid in the mixing chamber itself.
- the premixing ensures a uniform material density, which is necessary for the subsequent, in particular volumetric, metering. It would be conceivable to arrange the drive motor coaxially to the mixer shaft, for which purpose it would then have to be guided vertically through the silo container in the device according to the invention. This would be relatively difficult, especially with large storage containers.
- the drive motor is arranged on the side of the device and is connected to the mixer shaft via drive means.
- the motor shaft can be arranged parallel to the mixer shaft and preferably connected to it via a chain drive, or the motor shaft could also be arranged transversely to the mixer shaft and connected to it by means of a bevel gear, spur gear or universal joint.
- the drive means from the drive motor to the mixer shaft are expediently arranged in a closed drive housing which projects into the mixing device. This is possible without further ado because the mixing device can have a large passage cross-section due to its direct vertical arrangement in continuation of the outlet opening of the silo.
- the device according to the invention can also be used to process other materials or, for. B. colored by adding colored liquids.
- the processing of white lime hydrate into milk of lime is possible within a production process.
- a wide variety of substances for the production of mixtures within production or manufacturing processes could be metered and prepared with the device according to the invention.
- a screw pump can be provided as the feed pump. This can convey the mixture product mixed with liquid directly to a processing point or for further processing. Especially made-up mortar or plaster can be brought directly to the appropriate place in a building. It has been shown that larger distances can be bridged than if the dry mixture product with compressed air delivery were first conveyed to a mixing and mixing device.
- the premixing tool can preferably be arranged on the mixer shaft.
- the premixing tool can be arranged below the drive housing for the drive means and above the drive housing a preferably roof-shaped guide device can be provided, the ridge of which is directed against the outlet opening of the silo and the greatest width of which approximately corresponds to that of the drive housing.
- a preferably roof-shaped guide device can be provided, the ridge of which is directed against the outlet opening of the silo and the greatest width of which approximately corresponds to that of the drive housing.
- An embodiment of the invention of considerable importance can consist in that a drive shaft, preferably the mixer shaft, projects upward above the drive housing and that the premixing tool is arranged above the drive housing. This can ensure a good afterflow, especially in the case of goods that are difficult to flow.
- Embodiments of this premixing tool are the subject of claim 11.
- a particularly expedient embodiment can consist in the fact that the stirring blade is connected to the rotating body via a joint and can be pivoted in the joint perpendicular to the direction of rotation, the stirring blade surface being inclined to the direction of rotation, so that the stirring blade rotates through the bulk material in one movement when the rotating body rotates
- the direction of rotation can be opened automatically and in the other direction of rotation can be opened automatically, the opening preferably taking place into the funnel-shaped run-up area of the loading container.
- the inclination of the mixing paddle is therefore chosen so that when it passes through the material, a buoyancy component is created, which it opens in one direction of rotation, so that it can perform its stirring function well, while in the opposite direction the folding takes place automatically.
- the mixing device can be flanged directly to the silo, an intermediate piece is unnecessary, so that the device comes to lie correspondingly higher on the silo and this intermediate piece can be saved.
- the connecting flange or the like of the mixing device can have a plate-shaped continuation opposite to its pivoting direction, which closes the outlet opening of the silo when the mixing device is pivoted out (away from the silo opening) as a blind flange, slide or the like.
- the mixing device can be removed from the area of the silo and this can be tightly closed with a closure flap even if there is no intermediate piece.
- Embodiments of these different fastening options of the mixing device on the silo which enables the removal of the mixing device for cleaning or repair purposes, without an intermediate piece with a closure flap having to be arranged on the silo, are the subject of further claims.
- a device for measuring and / or limiting the current consumption of the drive motor is optionally provided with a cut-off control or cut-off control on the drive motor, which indicates in particular the rising of liquid in the premixing chamber and / or switches off the drive motor and in particular also the liquid supply.
- the mixing water rises within the device because, for example, the mixed mixture is not being conveyed quickly enough, it will reach the area of the pre-mixing tools and there increase the resistance for these tools. Accordingly, the current consumption of the drive motor increases. This can be used to initiate control processes that lower the liquid level or counteract the rising or switch off the device before the liquid can reach the area of the silo.
- a combination of the features and measures described above results in a device in which mixed material, which, for example, is already delivered in a loading silo or is to be removed from a storage silo, can be processed with little mechanical effort. In this case, only a single drive is required, with which the material to be mixed can get from the silo via a mixing device into a conveying or similar metering device. Accordingly, the operation is simple and the security is great.
- the plastering mortar because of the avoidance of segregation or the intended premixing, a uniform consistency and good pumpability up to a hose length of z. B. reach about 60 meters.
- excessive wear on the casing of a screw feed pump is not to be expected.
- the entire device can have a relatively low overall height, so that a sufficiently large supply can be provided in a silo, which can also be set up without foundations.
- a mixing and metering device designated as a whole by 1, hereinafter also referred to simply as a mixing device or only device 1, is used primarily for bulk goods, in particular Dosing and mixing building materials, fertilizers or the like, and in the exemplary embodiment also for further processing or conveying these bulk goods.
- the device 1 has a drive motor 2 and also includes a loading or storage silo 3 - called silo 3 for short - or is attached to such a silo 3, which in the exemplary embodiment is a silo 3 with feet 4 for it Lineup is about.
- the device 1 is fastened to the lower outlet opening 5 of this silo 3, which is particularly evident in FIGS. 2 to 11. This outlet opening 5 opens directly into the mixing device 1 and its cross section corresponds to that of a premixing chamber 8.
- a mixer shaft 6 for the mixing tool or tools 7 is arranged vertically under the outlet opening 5 of the silo 3 and that the device 1 has a premixing chamber 8 with at least one premixing tool 9 (FIG. 2), 10 (FIG. 4 ) or 11 (Fig. 6) is connected upstream.
- the drive motor 2 is arranged on the side of the device 1 and connected to the vertical mixer shaft 6 via drive or transmission means to be described.
- the motor shaft 12 is arranged parallel to the mixer shaft 6 and connected to it via a chain drive.
- the sprockets 13 can be seen in each of the exemplary embodiments, while the chain itself is not shown for the sake of clarity. However, it would also be possible to provide other drive means, for example a countershaft or the like. Furthermore, it would be possible to arrange the motor shaft 12 transversely to the mixer shaft 6 and to connect it to the latter by means of a bevel gear or spur gear or universal joint.
- the drive means 12 and 13 are arranged from the drive motor 2 to the mixer shaft 6 in a closed drive housing 14, which projects into the mixing device 1, hereinafter referred to as housing 14.
- the actual mixer with the mixing tool 7 is located coaxially below the premixing chamber 8, in the area of which at least one supply (not shown in detail) for liquid or mixing water can be provided.
- an opening 15 can be provided through which the mixing tool 7 draws air, so that the mixed mixture also contains air bubbles and air pores, which not only improves its conveyability, but later also leads, for example, to heat-insulating properties.
- a feed pump 16 preferably a screw pump, is arranged coaxially to the mixer shaft 6 and can pump the mixed mixture to its destination.
- hose 17 connected to the delivery pump 16 can have a correspondingly large length of up to approximately 60 meters, so that in the case of dressed plaster, it is also relatively high Buildings can be operated from a single location.
- Fig. 2 it is provided that for the premixing of the still dry material between the mixing chamber 18, which has the mixing tool 7 and the liquid supply, and the storage silo 3, at least one premixing tool 9 arranged in this case on the mixer shaft 6 is provided.
- a roof-shaped guide device 19 running in its longitudinal direction, the ridge 20 of which is directed against the outlet opening 5 and the greatest width of which corresponds approximately to that of the housing 14 for the drive means, which 3 can be seen. 2 this guide device 19 is also shown rotated by 90 ° in cross section to illustrate this cross section, but in reality it is arranged in the longitudinal direction of the housing 14.
- Fig. 3 shows that this guide device 19 can extend over the entire cross section of the premixing chamber 8 or only to the end of the housing 14.
- This guide device 19 halves the material stream emerging from the silo 3 in two parts, so that one-sided emptying of the silo 3 is avoided.
- the bulk material flow divided in this way can be detected and mixed by the premixing tool 9, so that any segregation that may have occurred is counteracted.
- FIGS. 4 and 6 show an embodiment in which a drive shaft, in this case the mixer shaft 6, projects upward above the housing 14 and carries at least one premixing tool 10 or 11 above this housing 14. This can improve the flow from the silo 3.
- These premixing tools 10 and 11 can be the only premixing tools, but they can also be combined with the premixing tool 9 below the housing 14 according to FIG. 2.
- FIG. 1 shows an embodiment with a fixed circumferential mixing finger 22 which, according to FIG. 1, is flat-iron-like and has a slightly oblique cross section in order to achieve a good stirring effect. It is indicated in dashed lines in FIG. 4 that this stirring finger 22 can also protrude into the region of the opening 5 and somewhat higher, in order to facilitate the subsequent flow.
- FIG. 6 shows an embodiment in which the mixing paddle 23 can protrude even higher into the silo 3 without, however, hindering the ability to assemble and disassemble the device 1.
- the mixing paddle 23 carries along with the drive tel and the housing 14 arranged rotating body or arm 21 at least one in the region of its outer circumference about a hinge 24 swivel or hinged paddle 23, which is also arranged with its cross section obliquely to the direction of rotation according to the arrow Pf 1 in Fig. 7, so that it due to the rotary movement within the material, such as a propeller or a screw, it moves automatically to the side and opens or collapses due to an opposite rotary movement.
- This is indicated by the double arrow Pf 2 in FIG. It can also be seen in Fig.
- the hinged agitator blade 23 forms an obtuse angle with its rotating body 21 in the working position and is approximately parallel to the funnel-shaped outlet area 25 of the silo 3, so that no bulk material can stick to it, but also for subsequent flow these marginal areas is taken care of. Nevertheless, the stirrer blade 23 does not protrude into the silo area in the rest position, so that disassembly or a lateral pivoting of the device 1 to be described later, from the area of the outlet opening 5 of the silo 3, is not hindered by this in the working position in the silo projecting mixing tools. It should be mentioned that, as a premixing tool, two opposing, in particular hinged, stirring blades 23 can optionally also be attached to the rotary arm 21.
- the motor shaft 12 also has two output gears, sprockets 26 or the like. one of which is connected to the corresponding sprocket 13 of the mixer shaft 6 via a corresponding drive means, a chain (not shown) in the exemplary embodiment, and the other of which is connected to a third drive wheel 27 for the premixing tool 11 arranged above the housing 14. It can clearly be seen that the mixer shaft 6 and a stub shaft 28 for the premixing tool 11 can be rotated independently of one another.
- the premixing tool 11 can preferably have a lower speed than the mixer shaft 6. This is particularly advantageous if the agitator blades 23 open up to a considerably larger circumference and if the rotational speed remains the same, the circumferential speed would be too high.
- the peripheral speed can thus be adapted to the material in the silo 3 by reducing the speed.
- FIGS. 2, 4, 6, 9 and 11 show how the silo 3 can nevertheless be closed when the device 1 is to be moved out of the area of its outlet opening 5. It can be seen in these figures that the mixing device 1 can be pivoted away parallel to itself, that is to say horizontally, from the region of the outlet opening 5 via a rotary connection 29 arranged to the side of the silo 3 and its outlet opening 5. This can be seen above all from the dashed representation in FIG. 8.
- the connecting flange 30 of the mixing device 1 has a plate-shaped extension 31 against its pivoting direction, which closes the outlet opening 5 of the silo 3 when the mixing device 1 is pivoted out as a blind flange, slide or the like and has a corresponding size.
- the somewhat curved shape of this plate-shaped continuation 31 can be seen well from the figure and it is clear from the dashed illustration that this bulged plate 31 has a circular section on its outer contour, the center of which is the axis of rotation 29.
- the adjoining contour with a narrower radius of curvature corresponds approximately to the circumferential circle of the connecting flange 30 and can thus reliably close the outlet opening 5 in the position shown in broken lines.
- a separate slide 32 can be seen between the outlet opening 5 of the silo 3 and the entry into the mixing device 1 and the mixing device 1 can be folded down about a horizontal axis 33 from the outlet opening 5 of the silo 3.
- the slide 32 can be pivoted about an eccentric vertical axis of rotation 34 according to the double arrow in FIG. 10 under the outlet opening 5 or away from it. If it is in the position indicated by the broken line under the outlet opening 5, the device 1 can be folded down about its pivot axis 33 and cleaned or repaired in this position.
- the edge 35 facing the outlet opening 5 can either be rounded or even sharpened on the blind flange 31 connected to the mixing device 1 or the swivel slide 32. As a result, these parts can then more easily cut through the material column initially protruding through the outlet opening 5 into the mixer 1 during the pivoting movement described for carrying out the closure.
- the mixing device 1 in the area of the liquid supply under a partition 36 arranged between the premixing chamber 8 and the actual mixing chamber 18 on a turntable 37 has both upwards and downwards directed mixing tools 7, the diameter the mixing chamber 18 significantly exceeds that of its outlet 38.
- the end face 39 of the mixing chamber 18 is rounded at the transition to the outlet 38 and in particular to the feed pump 16 connected to it in a funnel shape or also partially beveled, and the adjacent mixing tools 7 have a corresponding bevel in this area.
- liquid should rise from the mixing chamber 18 in the event of any malfunctions, it reaches the premixing chamber 8 and increases the resistance of the premixing tools, in particular a premixing tool 9.
- a device for measuring this motor 2 and / or limiting the current consumption can be provided, which can also shut down the liquid supply, but above all the drive motor 2, via a switch-off control or switch-off control, in order to switch off the entire mixing device 1 and to prevent the liquid from penetrating into the silo 3.
