Description

  The invention presupposes an apparatus for mixing at least two flowable components according to the preamble of claim 1.

  Mixing devices are commonly used when two or more flowable material or component streams must be mixed as a fully or partially mixed and flowable material stream. Mixing devices are used that are discarded or washed after use and reused repeatedly.

  In the adhesive industry field, it is known to use mixing devices for mixing reactive components. Here, these apparatuses are used both for mixing the components of the multi-component adhesive substantially uniformly and for mixing them in a layered manner in order to accelerate the curing of the single-component adhesive.

  A static mixer that performs mixing by repeatedly separating material strands and a dynamic mixer in which processed components are separated or swirled in multiple times by a movable member are known.

  A static mixer that has no moving parts (see Patent Document 1) is particularly suitable for mixing materials with low viscosity.

  Therefore, in order to mix a highly viscous material, it is preferable to use a dynamic mixer having a rotor rotatably provided in a mixing chamber into which the material to be mixed is introduced. This type of mixing apparatus is described in Patent Document 2, Patent Document 3, Patent Document 4, and Patent Document 5.

  The devices described in these documents have a rotor casing, which has two material openings used for introducing the components to be mixed and a drive opening. ing. A drive shaft can be introduced in a shape-coupled state through the drive opening and into the recess of the rotor.

  Various problems have been identified for known mixing devices. In order to supply the components to be mixed and to connect the drive shaft, the rotor casing must be provided with various openings and connections, resulting in increased manufacturing costs. Especially when mixing reactive components, the mixing device must be replaced after a relatively short operating time, correspondingly to the high cost of purchasing and processing the mixing device. It will be borne on the part of the person.

  Furthermore, mixing and feeding the material through the two openings in a separated state results in a relatively high energy consumption, resulting in unwanted heating of the reactive material. Will be done.

  It is expected that further unwanted heating will occur on the mixture. The reason is that the rotor seated on the drive shaft is held in place by the rotor casing when it is configured in one-way and therefore rubs there during operation. Because it becomes.

  As long as components having various volumetric proportions are used, the known mixing devices need to be correspondingly adapted, possibly with additional costs. For this purpose, in the device described in Patent Document 4, a deceleration chamber is provided for one of a plurality of components. In order to realize this deceleration chamber, a corresponding mold is required.

Furthermore, the mixing device described above cannot adjust the material flow and material properties. Therefore, there is a need for a corresponding controllable drive or mixing device that is configured in other shapes.
International Publication No. 02/32562 pamphlet European Patent Application No. 0301201 European Patent Application No. 1106243 German Patent Application Publication No. 10112904 European Patent Application No. 1106243

  The object of the present invention is to provide an improved dynamic mixer of the type described at the beginning.

  The dynamic mixer should be simple to configure, be manufacturable at a low cost, and be easy to operate. The part of the mixing device that is to be processed after use of the mixing device should be constructed in a particularly simple and low-cost manner and should be manufacturable with less material. Furthermore, it is possible to realize a mixing chamber with a small capacity of the dynamic mixer and possibly a transfer chamber so that only a small amount of mixed material is processed or removed when the dynamic mixer is completely replaced or serviced. Should be good.

  Furthermore, it would be desirable to be able to perform the mixing process with low energy demand in order to reduce material wear and generated process heat.

  Furthermore, it would be desirable to be able to achieve various mixing ratios of the components supplied with a single device. In that case, the mixing ratio should preferably be variably adapted according to the demand of the user.

  According to the invention, the above problem is solved by the features of claim 1. Further preferred configurations of the invention emerge from the dependent claims.

  The dynamic mixer of the present invention has a rotor connected to a drive shaft, and the rotor is rotatably provided in a mixing chamber provided in a rotor casing, and the mixing chamber includes at least a first one. And a second component can be provided. The drive shaft has at least one shaft passage, and the second component can be introduced into the mixing chamber through the shaft passage.

  By supplying the second component K2 through a passage provided in the drive shaft, the complexity of the mixing device can be greatly reduced. In order to supply the second component K2, it is not necessary to provide a separate connection in the rotor casing, so that the rotor casing can be constructed very simply and at low cost. Furthermore, the manufacture, maintenance, assembly and removal of parts to be processed after use, in particular the rotor and rotor casing, are simplified.

  The rotor has a body with rotor blades, the longitudinal axis of which is preferably oriented to be coaxial with the axis of the drive shaft, and the body has a connecting cylinder. The drive shaft can be introduced into the connecting cylinder. The drive shaft has at least a first closing member, and the driving shaft and the rotor can be connected so as not to rotate by the closing member. . Preferably, the rotor and drive shaft are connected using a screw connection or a bayonet connection so that the rotor is firmly fixed and does not risk colliding with the rotor casing. This prevents frictional heat from being generated. This frictional heat may accelerate the reaction process performed between the two components K1 and K2.

  The rotor and the drive shaft can reach at least one zone through which only the second component passes only through one or more transport passages in the rotor and the first component of the mixing chamber flows through. They are preferably connectable to each other. This provides various advantages. It is preferred if the second component K2 can be distributed in different streams impinging on the first component K1 in different zones of the mixing chamber. Thus, uniform mixing can be achieved with only a few revolutions of the rotor, i.e. with little mechanical energy and less process heat. This is particularly suitable for highly viscous materials. Accordingly, it is possible to prevent the portion of the mixture from being hardened earlier than the scheduled time in the mixing chamber, so that the usage time of the portion to be replaced after use is greatly extended.

  Furthermore, by suitably configuring the rotor, it is possible to accelerate the transfer of the first component K1 to the mixing chamber and the discharge of the mixture K1 × K2 from the mixing chamber. For example, a conveying member that preferably extends in a screw shape is provided outside the connecting cylinder, and / or an output screw is provided at the outlet end of the rotor casing.

  In a further preferred configuration, the rotor casing provided with the outlet opening has only one inlet opening. Through this inlet opening, a drive shaft that is already connected to the rotor and possibly the first component can be introduced. This allows the inlet opening and thus the entire rotor casing to be constructed very simply and manufactured at a minimum cost.

  The rotor casing can be easily constituted by a cylinder piece having an end piece provided on the front surface. The cylinder piece can be connected to the opening of the first apparatus body in a sealed state, and the drive shaft and thus the second component are guided through the opening. . A first transfer chamber is formed in the first apparatus body. The transfer chamber is connected to the first supply device, preferably the outlet opening of the first valve, and the first component K1 is passed through the outlet opening into the first transfer chamber. , And can be introduced into the mixing chamber along the drive shaft.

  The cylinder piece provided in the rotor casing has, for example, a male thread or an outer flange. This male threading can be connected to a female threaded first conveying chamber or a flange that is male threaded connected to the first conveying chamber by a nap cat. Therefore, the rotor and the rotor casing can be easily and quickly attached and detached.

  In order to introduce the second component K2 into the shaft passage, this shaft passage is connected to a second transfer chamber provided in the first or second device body, either directly or via an inlet passage. Yes. The drive shaft protrudes into the second transfer chamber, or passes through the second transfer chamber and passes through the drive shaft. The second transfer chamber is connected to the second supply device, preferably the outlet opening of the second valve, and the second component K2 passes through the outlet opening and the shaft passage. Can be introduced.

  The outlet opening of the first and / or second valve, which can be actuated mechanically, hydraulically or pneumatically, is preferably openable or closable by a needle, the needle being The elastic bearing member is supported inside the body so as to be axially displaceable. The elastic bearing member seals the outlet opening and the valve chamber that closes the inlet opening. In one preferred configuration, the resilient bearing member, preferably made of plastic or spring steel, has at least a generally plate or cylinder shape and is preferably secured in the annular groove adjacent to the valve chamber. Thereby, the treated components K1; K2 are prevented from entering between the bearing member and the wall of the valve chamber. Unlike piston-like bearing members guided along the wall of the valve chamber, the solution according to the invention does not impair the operation of the valve by the processed components. The bearing member has a diaphragm function. The diaphragm seals the valve chamber at the peripheral edge and deflects only the central portion to guide the held needle in the axial direction. The needle has at least an annular flange, for example, which is held by or embedded in a bearing member.

  Furthermore, the solution according to the invention makes it possible to adjust the amount and flow rate of the components K1, K2 to be conveyed with a simple procedure. For this purpose, the drive shaft is provided with a corresponding metering member, for example a metering ring, which stops the material flow in the flow areas of both components K1, K2. Since the capacity in the first transfer chamber can be further reduced by the metering ring, the deceleration time can be adjusted. After this deceleration time, the first component K1 enters the mixing chamber. Patent Document 4 describes that it may be more desirable to use a deceleration chamber. Therefore, by using the corresponding metering ring, the transfer chamber can be expanded to a deceleration chamber with variable capacity and deceleration time.

  Therefore, it can be seen that the dynamic mixer according to the present invention is very excellent for mixing components having various capacitance characteristics. By taking the device parts, in particular the drive shaft or metering element, to the corresponding dimensions, the device can be optimized in a simple manner for the desired volume ratio.

  Ingredients can be introduced into the transport chamber via supply lines or from locally mounted cartridges. At that time, the dynamic mixer according to the present invention can be preferably realized without a valve, particularly when the inertia of the components used is low. Of course, it is of course possible to simply connect two or more supply lines or valves that carry components guided into the mixing chamber inside or outside the drive shaft, for example in a further shaft passage.

  Embodiments of the present invention will be described below in detail with reference to the drawings. The same members are denoted by the same reference numerals in different drawings. The direction of media flow is indicated by arrows.

  Only those important components that are directly relevant to the understanding of the present invention are shown. For example, the drive unit 9 required for the operation of the dynamic mixer is not fully shown.

  FIG. 1 is a sectional view of a dynamic mixer according to the present invention. The dynamic mixer generally consists of a rotor housing 1 which is preferably rotationally symmetric and thus easy to manufacture. A mixing chamber 15 is provided inside the rotor housing, and at least the first and second components K1 and K2 can be mixed in the mixing chamber. In the mixing chamber 15, the rotor 2 having the body 21 provided with the blades 211 is rotatably held by the drive shaft 3. The drive shaft has a shaft passage 31 through which the second component K2 can be introduced into the mixing chamber 15.

  In the configuration shown, the rotor housing 1 has an outlet opening 152 used to discharge the mixture K1 × K2, and a single inlet opening 151. The components K1 and K2 to be mixed and the drive shaft 3 can be introduced into the rotor housing 1 through this inlet opening. The back surface portion of the rotor housing 1 is constituted by a cylinder piece 11. The front side of the cylinder piece is closed by an end piece 13 provided with an outlet opening 152.

  The drive shaft 3 passes through two device bodies 41 and 51 that are adjacent to each other. Through these device bodies, the components K1 and K2 to be mixed are introduced into the mixing chamber 15. For this purpose, the device bodies 41, 51 are provided with valves 4, 5. These valves have a valve chamber 42; 52 having an inlet opening 421; 521 and an outlet opening 422; 522 that can be closed or opened by a pneumatically or hydraulically operated needle valve 43; 53. ing. First and second transfer chambers 49 and 59 are formed between the openings 411 and 511 penetrating both the apparatus bodies 41 and 51 and the wall of the drive shaft 3 provided therein. The components K1 and K2 guided through the exit openings 422 and 522 enter into these transfer chambers. As shown in FIG. 3, the first component K <b> 1 passes through the first transfer chamber 49 along the outside of the drive shaft 3 and is supplied to the mixing chamber 15. The second component K2 is introduced from the second transfer chamber 59 through the inlet passage 32 provided in the drive shaft 3 into the shaft passage 31, and further guided to the mixing chamber 15.

  One side of the first transfer chamber 49 is separated from the bearing member 36 by a first sealing portion 351. The drive shaft 3 is rotatably held inside the device bodies 41 and 51 by this support member. The other side of the first transfer chamber 49 is open to the mixing chamber 15. Since both sides of the second transfer chamber 59 are closed by the second and third sealing portions 352 and 353, the supplied second component K2 passes only through the inlet passage 32 and the shaft passage 31. Thus, it is possible to escape from the drive shaft 3.

  The connection between the rotor 2 and the shaft 3 in this preferred configuration is shown enlarged in FIG. The rotor 2 has a connecting cylinder 22 formed integrally with the rotor body 21 on the inlet side. An end piece of the drive shaft 3 is fixed inside the connecting cylinder. The end piece is provided with an outlet opening of the shaft passage 31. For this purpose, the connecting cylinder 22 is preferably integrated with a metal connecting sleeve 7. The connection sleeve has at least one connection passage 71. Since the connecting member 33 connected to the drive shaft 3 can be introduced through the connecting passage and restrained there, a plug-in connection is established as a result. Since the inner wall of the connecting sleeve 7 is closely adjacent to the drive shaft 3, the second component K2 coming out of it passes only through the conveying passages 72, 212 in the connecting sleeve 7 and the connecting cylinder 22, The zone of the mixing chamber 15 through which the first component K1 flows can be reached. Naturally, it is preferred that a sealing member such as an O-ring can be placed on the drive shaft 3 in order to separate and seal the individual zones and chambers from each other. One or a plurality of transport passages 212 pass through the rotor 2. The second component K <b> 2 is distributed to a plurality of flows passing through arbitrary portions in the mixing chamber 15 through the conveyance path. Therefore, in this preferred configuration, mixing the components K1, K2 is not performed solely by the rotor 2, but is preferably performed by distributing and supplying the second component K2 as intended. Thus, the complete mixing of the required components K1, K2 can be achieved with only a few revolutions of the rotor 2. Therefore, only a little heat is supplied to the mixture K1 × K2. This heat can accelerate the reaction process performed therein in an undesirable manner. Further, by stably attaching the rotor 2, the rotor may slide forward or tilt to the side and rub against the inner wall of the rotor casing 1 to supply disturbing frictional heat to the mixture K1 × K2. Is prevented. Therefore, in the dynamic mixer according to the present invention, the substantial variable that affects the mixing process and affects the reaction process of the components K1 and K2 is significantly reduced.

  Furthermore, it can be seen from FIG. 2 that the threading is applied to the outside of the connecting cylinder 22, which functions as an input screw 221 that accelerates or decelerates the first component K 1 and conveys it into the mixing chamber 15. By appropriately selecting the threading or rotation direction and the lead in the region of the connecting cylinder 22, the chamber 16 having an appropriate deceleration or acceleration can be constructed, but at this time, the rotor casing 1 is more costly. There is no need to configure. The generated mixture K1 × K2 is conveyed toward the outlet opening 152 of the rotor casing 1 by the output screw 23 formed integrally with the rotor body 21 on the outside.

  Although the plurality of functions are realized in this way, the rotor casing 1 can be configured very easily. Since both the components K1, K2 and the drive shaft 3 can be introduced through only the opening 151, only the cylinder piece 11 having a simple configuration can be provided on the inlet side. This cylinder piece is introduced into a correspondingly adapted opening 411 of the first device body 41. In order to fix the rotor casing 1, the cylinder piece 11 has an outer flange 12. The outer flange is drawn by the cap nut 6 toward the flange 48 that is formed integrally with the first device body 41 and is male threaded. Therefore, the rotor casing 1 can be easily attached and detached. By supplying the components K1 and K2 in a separated state up to the inside of the mixing chamber 15, the connection and connection members 3, 7 or 6, 22, 48 are prevented from sticking. Therefore, the device parts 1, 2, 3, 4 can be separated and cleaned without any problem.

  The use of the drive shaft 3 for conveying the components K1, K2 on its inside and outside also makes it possible to easily stop the material flow. For this purpose, a first metering ring 81 can be mounted on the drive shaft 3 as shown in FIG. This first metering ring partially fills the first transfer chamber 49 and reduces the cross section of the first transfer chamber. Therefore, the flow rate of the material K1 conveyed through the first transfer chamber 49 can be increased, and at the same time, the flow rate can be decreased because the resistance is increased. The second metering ring 82 can reduce the diameter of the outlet opening of the shaft passage 31. The metering rings 81 and 82 are, for example, internally threaded, and the drive shaft 3 is correspondingly threaded. Further, an insertion portion provided with a hole therein can be inserted into the shaft passage 31. This hole is reduced in diameter. Furthermore, a cover provided with an outlet opening can be placed on the drive shaft 3.

  As can be seen from FIG. 1, the rotor casing 1, the rotor 2, and the drive shaft 3 that can be connected to the drive device 9 by the connecting member 91 are oriented coaxially with the axis x. Instead of the valve bodies 41, 51 shown in FIG. 1, a single device body can be used. Supply lines for components K1 and K2 can be connected to the apparatus body. Therefore, the dynamic mixer can be configured to be extremely thin and can be easily operated.

  As can be seen from FIGS. 1, 4 and 5, it is preferable to integrate the valves 4 and 5 into the dynamic mixer. It is preferable to use separate valves 4 and 5 having dedicated valve bodies 41 and 51 for each component K1; K2 to be supplied. The valve body has through holes or holes 411 and 511 for allowing the drive shaft 3 to pass therethrough. As described above, the valve body has a valve chamber 42; 52 having an inlet opening 421; 521 and an outlet opening 422; 522. These openings can be closed or opened by a pneumatically or hydraulically actuated needle valve 43; 53, whereby the first or second component K1, K2 is transferred to the associated transfer chamber 49, Operate to 59 and carry. The needle valve 43; 53 is supported by the bearing member 44; 54 so as to be displaceable in the axial direction, and is held by the piston 46; This piston is movably carried inside the pressure chambers 45 and 55. A pneumatic medium or a hydraulic medium can be supplied to the pressure chamber via pressure passages 451 and 551. The upper part of the pressure chamber 45; 55 is closed by a cover 452; 552, in which a spring 47; 57 is held. This spring always presses the pistons 46; 56 and thus the needle valves 43; 53 downward, so that the outlet openings 422; 522 are open when the medium is not being pumped into the pressure chambers 45; 55. Always closed.

  Accordingly, the needle valve 43; 53 in contact with the supplied component K1; K2 on one side is displaced axially within the bearing member 44; 55 or with the bearing member 44; 54. The In this case, the corresponding components K1; K2 can penetrate into the region between the bearing member 44; 54 and the needle valve 43; 53 or into the region between the bearing member 44; 54 and the outer wall, thereby The bearing function may be damaged.

  This problem is solved in the case of the valve 4 ′ shown in FIGS. 6 a and 6 b by using an elastic bearing member 440 instead of the inelastic bearing member 44. The elastic bearing member is held in the annular groove 414 adjacent to the valve chamber 42, for example, at the peripheral portion, and is connected to the needle valve 43 at the center. As can be seen, the needle valve 43 may be surrounded by an annular flange 432. The annular flange is embedded in a bearing member 440 made of plastic, for example. The bearing member 440 may be adjacent to the annular flange 432 on both sides. During the operation of the valve 4 ', the bearing member 440 held at the periphery is deflected like a diaphragm by the needle valve 43 as shown in FIG. The outlet opening 422 of the chamber 42 is made available. The needle valve 43 can again be operated mechanically, pneumatically or hydraulically.

  Therefore, in this device, it is preferred that the bearing member 440 safely closes the valve chamber 42, thereby ensuring that the operation of the valve 4 'is maintenance-free. Furthermore, the restoring force required for the operation of the valve 4 ′ is generated completely or at least partly by the bearing member 440, so that the restoring spring 47 can possibly be omitted. Is preferred.

  FIG. 7a shows a further preferred configuration of the first valve 4 ″ according to FIG. 6a. In this configuration, a compressible bearing member 440 ′ is provided instead of the elastic bearing member 440. The compressible bearing member holds the needle 43 and carries the needle in a vertically displaceable manner.The bearing member 440 'is a flexible compressible material, for example very Made of soft elastic elastomer.

  Particularly suitable in this configuration is that the needle 43 is guided correctly in this solution, but does not deflect and only the bearing member 440 'is locally compressed, so that the valve 4 " This means that there is little or no material being pushed when closing or when the needle 43 is retracted, as long as the annular flange 432 is held inside the compressible bearing member 440 '. The material segments are only compressed as shown in FIG. 7b, so that there is virtually no deformation outside the bearing member 440 ′. Therefore, there is an extra in opening and closing the valve 4 ″ The change in pressure makes the coating pattern uncontrollable, but this is prevented by the compressible member 440 '.

  In order to prevent the bearing member 440 'from being compressed but deflected, a closing plate 414A is provided outside the bearing member. This closure plate has an opening used to pass the needle 43 and, in a preferred configuration, a male thread. By this male threading, the closure plate is screwed to the inner flange 414C, which defines an annular groove 414 on one side.

  Fig. 7b shows the valve 4 "of Fig. 7a with the upwardly deflected needle 43 and the outlet opening 412 opened thereby. Further, the appearance of the bearing member 440 'is not significantly deformed. It is schematically shown that the material of the bearing member 440 ′ between the annular flange 432 and the closing plate 414 A is compressed at this position of the needle 43.

  Even in this configuration, the bearing member 440 ′ reliably seals the valve chamber 42, so that the operation of the valve 4 ″ is guaranteed to be maintenance-free.

  Fig. 7c shows the valve 4 "of Fig. 7a with a compressible bearing member 40 'supported on both sides by closing plates 414A, 414B. With this arrangement, the appearance of the bearing member 440' is Since the deformation and deflection in both directions are prevented, the valve function is further optimized.

  The dynamic mixer according to the present invention has been described and illustrated in a preferred configuration. Based on the principle according to the invention, the person skilled in the art can easily realize further configurations. In particular, the device bodies 41 and 51 carry the drive shaft 3 therein and are connected to the rotor casing 1 on the front side. The device bodies are configured in various forms, thereby It can be adapted to the demands of the user each time. The device bodies 41 and 51 can be composed of one or a plurality of members connected to each other. The valve can be provided on or in the device body 41, 51 or adjacent to an external pressure generator. This pressure generator is connected to the dynamic mixer via a supply line. The connection between the rotor casing 1 and the device bodies 41 and 51 and the connection between the rotor 2 and the drive shaft 3 may be performed by other methods. Further, a plurality of shaft passages 31 may be provided in the drive shaft 3. It is preferable to convey the component K1 having a small capacity characteristic through the drive shaft 3. However, the capacity characteristics can be freely selected by selecting or adjusting according to the corresponding device parameters or metering elements.

  Furthermore, the simple structure of the apparatus makes it possible to realize the mixing chamber 15, the deceleration chamber 16 provided in some cases, and the transfer chambers 49 and 59 with a minimum capacity. When the mixer is completely removed or serviced, only a small amount of mixed material needs to be removed or removed.

  Although the connection of the drive shaft 3 to the rotor 2 has been shown in a preferred configuration, it is naturally possible to use a gear such as an angle gear, for example.

It is longitudinal direction sectional drawing of the dynamic mixer which concerns on this invention. This dynamic mixer has a rotor 2 provided in the casing 1 on the front side. This rotor is connected to the drive shaft 3. The drive shaft can be connected to the drive device by a connecting piece 91 and passes through two transfer chambers 49 and 59 that are spaced apart from each other. These transfer chambers are provided in the bodies of the two valves 4 and 5. These valves are used to control the supply of the components K1, K2 to be mixed. FIG. 2 is a detailed view of FIG. 1 showing the connection between the rotor 2 and the drive shaft 3.
