Description

  The present invention relates to a technique for mixing a granular material or a liquid.

  Currently, various techniques are known for mixing fluids such as granular materials and liquids. For example, as a mixer generally used for mixing powder particles, there is a so-called V-type vessel or ball mill. Or when mixing a liquid, the mixer which rotates a propeller in the liquid stored in the container is known.

  However, although this type of mixer is suitable for roughly mixing a large amount of fluid, a local mixing ratio bias cannot be avoided.

  On the other hand, for example, in Patent Document 1, in order to eliminate variations in characteristics between production lots and handling lots, the lots are once divided into several equal parts, and the lots are collected and mixed one by one. There is a description about the multi-lot partial mixing method. In FIG. 1 of Patent Document 1, there is disclosed a division / reduction unit 1, 2, 2 ′ for dividing each lot into several equal parts.

  As described above, Patent Document 2 also discloses a channel dividing mechanism that repeatedly divides a channel into two. In patent document 2, it is the structure which mixes, after dividing multiple types of fluid into a small flow.

  Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. However, the components described in the following embodiments are merely examples, and are not intended to limit the technical scope of the present invention only to them.

(Overview)
The embodiment of the present invention described below relates to a mixing apparatus for mixing a first mixture and a second mixture. This mixing apparatus has at least a first and a second divided channel, at least two mixing channels, and an aggregation channel. Among these, the first divided flow path includes a first input port for supplying the first mixture, and at least two first discharge ports for dividing and discharging the first mixture input from the first input port. And comprising. Further, the second divided flow path includes a second inlet for introducing the second mixture, at least two second outlets for dividing and discharging the second mixture introduced from the second inlet, Is provided. Further, the mixing channel is connected to one of the first outlet and one of the second outlets, and the first mixture discharged from the first outlet and the second target discharged from the second outlet. Mix with the mixture to form a mixture. On the other hand, the aggregation channel aggregates the mixture discharged from the mixing channel.
That is, the mixing apparatus according to the present embodiment is configured by three stages of flow paths, a divided flow path, a mixed flow path, and an agglomeration flow path. The mixtures are mixed in the mixing channel and aggregated.

  In this way, the mixture ratio is reduced in a small amount of the local mixture by reducing the amount of the mixture using the divided flow path, mixing the reduced amounts of the mixture to form a mixture, and aggregating the generated mixture. A mixture can be obtained while ensuring the above. In other words, the mosaic pattern of the first mixture and the second mixture is seen as a whole, and any mosaic of the first mixture and the second mixture is enlarged even if any part is enlarged. It is possible to obtain a mixture with high mixing accuracy such as a pattern. In particular, since the mixture is aggregated in the aggregation channel before being conveyed or accommodated, segregation separation after accommodation or during conveyance can be prevented.

(First embodiment)
[overall structure]
FIG. 1 is a diagram showing a schematic configuration of a mixing apparatus 1 as a first embodiment of the present invention. The mixing apparatus 1 includes a dividing board 1001 as a dividing channel for the mixture A, a dividing board 1002 as a dividing channel for the mixture B, a mixing block 1003 including a plurality of mixing channels, and a plurality of aggregations. An aggregation block 1004 including a flow path, a belt conveyor 1005 as a conveyance path, and a container 1006 as a storage unit are included.

  The dividing boards 1001 and 1002 are provided with a dividing flow path for dividing the mixture to be reduced in quantity. Here, each of the divided boards 1001 and 1002 is divided into three stages and divided into eight in total. The number of divisions by the division boards 1001 and 1002 is the same. Each of the divided boards 1001 and 1002 can change an angle. For example, it is desirable to stand up the divided boards 1001 and 1002 in the vertical direction in the figure for a mixture with a low specific gravity, and to lay the divided boards 1001 and 1002 in the horizontal direction in the figure for a mixture with a high specific gravity. . This is because a mixture having a small specific gravity is likely to be dispersed in the divided flow path due to air resistance, whereas a mixture having a large specific gravity is likely to be ubiquitous in the divided flow path. If the divided boards 1001 and 1002 are laid down, the number of times or the probability that the mixed material comes into contact with or collides with the wall surface of the divided flow path due to its own weight increases, so that the mixed material having a large specific gravity flows in an uneven manner in the divided flow path. Can be prevented. On the other hand, in the case of a mixture having a small specific gravity, if the divided boards 1001 and 1002 are laid down, the flow rate may become extremely small. Therefore, it is preferable to raise the divided boards 1001 and 1002. That is, the divided board 1001 and the divided board 1002 do not have to be symmetrically arranged. Although not shown in FIG. 1, each of the divided boards 1001 and 1002 may be provided with a lid.

  The mixture to be divided by the division boards 1001 and 1002 is then charged into the mixing block 1003. In the mixing block 1003, the mixture A discharged from the outlet of the dividing board 1001 and the mixture B discharged from the outlet of the dividing board 1002 are mixed to generate a mixture. Since these to-be-mixed materials are reduced in volume, the to-be-mixed A and the second to-be-mixed B can be mixed little by little in the flow, and a local mixing ratio can be ensured. The mixing block 1003 has the same number of input ports as the number of division boards 1001 and 1002. One outlet of the dividing board 1001 and one outlet of the dividing board 1002 are connected to one mixing channel, and a partial mixture is generated in each mixing channel.

  The generated partial mixture is sent to the aggregation block 1004 and aggregated in each aggregation channel. The agglomeration block 1004 performs agglomeration treatment on the freshly mixed partial mixture discharged from each discharge port of the mixing block 1003 to generate a lump so that the particles of the partial mixture are not easily separated. Aggregation means that when the mixture to be mixed is a granular material, particles are adhered to each other to form a lump. When the mixture to be mixed is a fluid, it is prevented from being separated by a method such as gelling. It shows that. The partial mixture discharged from the aggregation block 1004 is placed on the belt conveyor 1005. Since the belt conveyor 1005 is driven in the direction of the arrow by a motor (not shown), the placed partial mixture is sent to the storage unit 1006 and stored. At this time, aggregation in the aggregation channel prevents segregation during conveyance.

[Configuration of divided flow path]
FIG. 2 is a perspective view showing the configuration of the divided board 1001. Since the configuration of the division board 1002 is the same as that of the division board 1001, the description thereof is omitted here. The dividing board 1001 is formed with one input port 1001a into which the mixture A is input and a groove forming a flow path. The groove has an inverted Y shape, and one upstream channel is connected to two downstream channels. Thereby, the to-be-mixed material which has flowed collides with the branch and is repeatedly divided into two. Further, at least two discharge ports 1001b through which the mixture A input from the input port 1001a is divided and discharged are provided on the most downstream side of the flow path. As described above, in the present embodiment, eight divisions 1001b are provided in order to divide the mixture to be divided into eight parts by repeating three divisions three times.

  A flow meter (for example, an impact type flow meter disclosed in Japanese Patent Application Laid-Open No. 2004-138574 proposed by the present inventor) is arranged for each discharge port 1001b of the divided flow path 1001, and each discharge amount is a desired amount. An angle adjustment mechanism that adjusts the angle in real time may be provided. Further, it is preferable that the divided flow path has high fluidity, and it is desirable to realize a high-temperature drying environment so as not to become a lump.

  The divided flow path 1001 has a shape in which the mixture is divided into eight parts by three stages of two divisions, but the present invention is not limited to this, and is divided into n-th powers of 2 in four stages or more. May be. For example, if a five-stage branch structure is used, 32 divisions are possible.

  The divided flow path may be configured by a groove and a lid formed by cutting a single plate, or may be configured by forming a flow path by attaching a plurality of partition plates to a single plate. Furthermore, a flow path formed by connecting flow pipes such as pipes may be used.

  Furthermore, it is also preferable to apply vertical reciprocating vibration, horizontal reciprocating vibration, or horizontal circular vibration in the divided flow path in order to make it difficult for the granular material to adhere to the wall surface. In a vacuum environment, vibration is also effective to disperse the agglomerated particles and disperse them well. Furthermore, if the wall surface member of the fluid is made of an elastic body and vibrated, it is possible to more effectively drop the granular material attached to the wall surface. It is important to coat the surface of the flow path with a member having a small friction coefficient in order to prevent adhesion of the granular material to the inner wall of the flow path. Such a coating can also improve the wear resistance of the inner wall of the flow path. For example, it is also preferable to coat only the upper side of the wedge-shaped portion at the branch point to reduce the friction coefficient. This is because that part is the part most subject to collision by the mixture.

[Configuration of mixing channel]
A detailed configuration of the mixing block 1003 is shown in FIG. The mixing block 1003 is a tubular member provided with partition plates 1003a to 1003g according to the number of divisions in the division flow path. A configuration may be employed in which the products A and B jump into one opening, or a configuration in which the products A and B are reliably mixed in the mixing block by inserting a separate partition plate 1101. The partition plate 1101 also has a function of preventing the mixture discharged from the adjacent divided flow channels from being mixed before being introduced into the mixing flow channel. FIG. 4 shows a mixing block 1401 having a flow path shape different from that in FIG. The mixing block 1401 has a smaller discharge port than that shown in FIG. Therefore, the probability that the materials to be mixed will collide with each other is high, and the mixing effect is high. A partition plate 1101 shown in FIG. 3 may be combined with the mixing block 1401.

  FIG. 5 shows various mechanisms for promoting the mixing effect between the objects to be mixed. FIG. 5A shows a configuration in which the materials to be mixed A and B collide with each other at an angle in the mixing channel. Basically, in order to promote mixing, it is preferable that the flow paths of the materials to be mixed (flight paths in the case of powder particles) intersect. 5 (b) and 5 (c) cause the turbulent flow by causing the plates and protrusions that the mixtures A and B collide to protrude from the wall surface to promote mixing. FIG. 5D shows a configuration in which the entire mixing channel is vibrated in the direction of the channel or in a direction perpendicular to the channel so that the mixture in the channel moves in the channel and as a result mixes well. is there.

  FIG. 5E shows a case where turbulent flow is caused by feeding air into the mixing flow path to promote mixing. The gas fed here is not limited to air, and nitrogen gas, helium gas, or the like may be used in accordance with the specific gravity and properties of the mixture. For example, when the specific gravity of the mixture is light, it is desirable to ensure a flow rate by flowing helium gas having a light specific gravity. Alternatively, an inert gas such as argon may be used in the case of a granular material that reacts with air, such as a metal that easily oxidizes.

  5 (f) to 5 (h) generate a magnetic field or an electric field and apply a force to a mixture such as a granular material. For example, in FIG. 5 (f), by alternately energizing two electromagnets arranged at positions sandwiching the mixing flow path, the mixture to be magnetic can be moved in the left-right direction in the figure, and mixed. Can be promoted. Similarly, as shown in FIG. 5 (g), a minute mixture is electrophoresed in the left-right direction in the figure by alternately energizing two electrodes arranged at positions sandwiching the mixing channel. And can promote mixing. Furthermore, as shown in FIG. 5 (h), the mixture in the flow path can be accelerated or decelerated by arranging a plurality of electrodes or electromagnets along the flow path and sequentially energizing them with different phases. As a result, mixing can be promoted.

[Composition of aggregation channel]
Various configuration examples of the aggregation flow channel in the specific aggregation block 1004 are shown in FIG. In the aggregation channel of FIG. 6A, a liquid such as water or ethanol or an adhesive is sprayed so that the mixtures are aggregated so that segregation does not occur. In the aggregation flow channel of FIG. 6B, the gas between the particles is reduced by reducing the pressure in order to assist aggregation due to electrostatic force or van der Waals force. This is particularly effective when the material to be mixed is a granular material having small grains and a small specific gravity. FIG. 6C uses an electrode and a charging device that aggregate the mixture by charging. 6D and 6E, direct heating or induction heating is performed using a heating device in order to promote the aggregation of the mixtures by melting. In the aggregation channel in FIG. 6 (f), a cooling device is used to promote the aggregation of the mixtures by solidification.

[Effect of this embodiment]
As described above, the mixing apparatus according to the present embodiment reduces the amount of the mixture using the divided flow path, mixes the reduced amounts of the mixture to generate a mixture, and aggregates the generated mixture. Thereby, a mixture with high mixing accuracy can be obtained as a whole while ensuring a local mixing ratio in a small amount of the mixture. Moreover, according to this mixing apparatus, the to-be-mixed materials from which quantities differ, the to-be-mixed materials from which shapes differ, the to-be-mixed materials from which magnitude | sizes differ, or the to-be-mixed materials from which weight differs can be mixed with high mixing precision. In particular, in the present embodiment, since each flow path is planarly configured, a mixing apparatus with high mixing accuracy can be provided with a simple configuration that saves space. Furthermore, after the mixing and before the conveyance, the aggregation is concentrated in the aggregation channel, so that segregation can be prevented and the final mixing accuracy can be further improved. In addition, you may utilize what is called a solidification process as an aggregation process here.

  In addition, although this embodiment demonstrated the mixing apparatus which employ | adopted the belt conveyor as a conveyance path, this invention is not limited to this. The conveyance path of another form may be arrange | positioned downstream of the aggregation flow path, or the structure which accommodates a mixture in an accommodating part directly from an aggregation flow path may be sufficient. Even in that case, since the partial mixture produced by mixing little by little is agglomerated, segregation during transportation or after storage can be prevented, and the mixing accuracy can be improved.

(Second Embodiment)
FIG. 7 is a diagram showing a schematic configuration of the mixing apparatus 2 as the second embodiment of the present invention. When compared with the mixing apparatus 1 of the first embodiment, the mixing apparatus 2 includes a conveyance flow path 2005 provided with an inclination instead of the belt conveyor 1005 as a conveyance path.
If the partial mixture is transported by this method, a drive source such as a motor is not required for transport, so that adverse effects due to energy consumption and vibration can be suppressed.

(Third embodiment)
FIG. 8 is a cross-sectional view showing a schematic configuration of the mixing apparatus 3 as the third embodiment of the present invention. The mixing apparatus 3 according to the present embodiment adds divided channels 1801 and 1802 for the mixtures C and D to the mixing apparatuses 1 and 2 of the first and second embodiments, and the mixtures A, B, C and D are mixed. Since the other configurations of the mixing apparatus are the same, the same components are denoted by the same reference numerals and description thereof is omitted. In the mixing device 3, the mixture to be mixed flows from the outlets of the four divided channels simultaneously into one inlet of the mixing channel 1003.

  According to this embodiment, it is possible to accurately mix four types of materials to be mixed with a simple and space-saving configuration.

(Other embodiments)
The following modifications can be considered with respect to the mixing apparatus shown in the first to third embodiments.

[Mixed material]
In the first to third embodiments, an object to be mixed is simply referred to as a “mixture”, but actually, the mixture includes powder, liquid, and gas. Among these, the powder includes industrial products, foods, and medicinal chemicals. The powder as an industrial product includes powders of carbon, sand, cement, glass beads, ceramics, abrasives, synthetic resins and the like. Further, the powder as food includes wheat flour, coffee, dairy products, brewer's yeast, spices, salt, sugar, starch, and other seasonings. Furthermore, powders as medicinal chemicals include granules, cosmetics, powders, feeds, detergents, powder paints, DNA, proteins and the like. Similarly, industrial products, foods, and medicinal chemicals can be considered as liquids and gases. For example, a liquid in which the above powder is melted is included.

[Flow path]
In the first to third embodiments, the generation method and shape of the divided flow channel, the mixing flow channel, and the aggregation flow channel are not described in detail, but the flow channel is a groove formed by cutting with an NC end mill. Or it may be a groove manufactured by injection molding. Alternatively, the flow path may be formed by bonding a flow path wall to the plate-like member, or the flow path may be formed by connecting a pipe. In addition to the groove having the corner as shown in FIG. 9A, the shape of the cross section of the flow path may be a groove having a corner at the corner as shown in FIG. 9B. As shown in FIG. 9C, the bottom surface may be an arc-shaped groove. If the groove has a radius as shown in FIGS. 9B and 9C, there is an effect that the flow path can be easily cleaned.

  In the divided flow path, it is preferable to make the total cross-sectional area of the flow path constant regardless of the distance from the inlet. Thereby, the density (fluid pressure) of the mixture flowing per unit area can be made constant from the inlet to the outlet, and the behavior of the mixture can be made constant regardless of the position in the flow path.

  On the other hand, if the material to be mixed is a powder and it can be assumed that the particles move straightly, the channel length of the mixing channel is proportional to the cross-sectional diameter in order to keep the number of particles hitting the wall constant. It is desirable to set the flow path length. In other words, the larger the cross-sectional area of the mixing channel, the longer the channel for mixing. This is because the number of particles hitting the wall is inversely proportional to the cross-sectional area. Since it is better for the particles to collide with each other, the angle at which the two divided flow channels intersect at the entrance of the mixing flow channel should be large to some extent. In particular, when the specific gravity of the mixture is large, the crossing angle should be large. On the contrary, in the aggregation channel, it is better that the particles do not collide with each other. For this reason, the angle at which the channels intersect in the aggregation process is preferably small.

  On the other hand, in the divided flow channel, it is preferable that the flow channel length in each branched route is the same. That is, it is better that the length of the mixture to be in contact with the wall surface in the flow path is the same in any route passing through the flow path. If it does so, even if a to-be-mixed material is a viscous fluid, the to-be-mixed material initially divided | segmented on the way will reach an exit theoretically at the same timing, and it becomes easy to control mixing accuracy.

  About the division | segmentation flow path as described in 1st thru | or 3rd Embodiment, as shown in FIG. 10, you may provide the division | segmentation amount adjustment parts 2301-2307 which can rotate in each branch location of a division | segmentation flow path. The division amount adjusting units 2301 to 2307 adjust the division ratios at the branching locations by rotating the plate-like member having the corners to the left and right in the drawing around the axis. Basically, adjustment is performed so that the mixture to be mixed has an equal flow rate, but the division ratio may be changed intentionally. By installing a flow rate sensor at each outlet of the divided flow path and measuring the flow rate of the mixture, the rotation direction and angle of each divided amount adjusting unit can be determined.

  For example, if the discharge amounts from the respective discharge ports are D1 to D8 as shown in FIG. 10, first, the division amount adjusting units 2304 to 2307 are set such that D1 = D2, D3 = D4, D5 = D6, and D7 = D8. Determine each angle. Next, the angles of the division amount adjustment units 2302 and 2303 are determined so that D1 + D2 = D3 + D4 and D5 + D6 = D7 + D8. Further, the angle of the division amount adjusting unit 2301 is determined so that D1 + D2 + D3 + D4 = D5 + D6 + D7 + D8. In this way, by repeatedly adjusting from the downstream dividing amount adjusting unit to the upstream dividing amount adjusting unit, the discharge amount from all the discharge ports is controlled to be equal at the time of installation or in real time. be able to.

[Production method of special mixture]
On the other hand, as shown in FIG. 11, the division amount adjusting unit is controlled so that the ratio of the discharge amounts D1 to D8 from the discharge ports becomes 1: 2: 3: 4: 5: 6: 7: 8. You can also. For this purpose, first, the division amount adjusting units 2304 and 2305 are set so that the discharge amounts D1: D2 = 1: 2, D3: D4 = 3: 4, D5: D6 = 5: 6, and D7: D8 = 7: 8. 2306 and 2307 are adjusted. Next, the division amount adjustment units 2302 and 2303 are adjusted so that the discharge amounts D1 + D2: D3 + D4 = 3: 7 and D5 + D6: D7 + D8 = 11: 15. Finally, the division amount adjustment unit 2301 is adjusted so that the discharge amount D1 + D2 + D3 + D4: D5 + D6 + D7 + D8 = 10: 26.

  If this concept is applied, the ratio of the mixture discharged from each outlet of the divided flow path can be freely changed. If it does so, it will become possible to change the mixing ratio of to-be-mixed A and B discharged | emitted from two division flow paths for every mixing flow path. For example, the mixing channel A: B can be changed from 1: 8 to 8: 1. If the mixtures having different mixing ratios are sequentially conveyed and stored, a mixture 2701 having gradation as shown in FIG. 12 can be obtained.

  The gradation mixture 2701 in FIG. 12 can be manufactured by changing the ratio of the mixture to be added to the mixing apparatus according to any one of the first to third embodiments. If the input amount of the mixture is gradually changed from the state of the mixture A 100% mixture B 0% to the state of the mixture A 0% mixture B 100%, a gradation mixing column 2701 in which the mixing ratio continuously changes is generated. Can do.

  Furthermore, as shown in FIG. 13, in the production | generation apparatus 2801 for producing | generating a columnar member from the mixture discharged | emitted from the mixing apparatus, since it has the structure attracted | sucked from the wall surface, the mixture discharged | emitted previously is The mixture is placed so as to stick to the wall surface and gradually fill the interior. 11 and 12, if the mixing ratio of the mixture discharged from the mixing device is changed with time and the gradation mixture is fed into the generating device 2801, the mixing of the mixture from the center toward the outer periphery is performed. A gradation mixed column 2802 in which the ratio gradually changes can be generated.

  Thus, the generation of the gradation mixture makes it possible to bond dissimilar materials. For example, the bonding of metal and ceramic is considered to be very difficult, but as described above, if a gradation mixed column is produced by mixing metal powder and ceramic powder, it is a single rod-shaped member, An object whose material continuously changes from one end to the other can be created.

[atmosphere]
In the first to third embodiments, the atmosphere of the mixing device is not described in detail, but the above-described mixing device can also perform the mixing process in a reduced pressure or vacuum environment exhausted by a vacuum pump. Alternatively, a desired gas may be introduced from a cylinder and the entire mixing apparatus may be placed in a gas atmosphere to perform the mixing process. Here, as the gas, nitrogen, argon, water vapor or the like may be selected according to the object.

  When the specific gravity of the mixture is very small, the air resistance is excessively received, and the flow velocity under its own weight may be very small. In this case, it is desirable to suppress the air resistance by putting the entire apparatus in a vacuum or a reduced pressure environment. Although the phenomenon of particles becoming agglomerated under vacuum or reduced pressure may occur, in the divided flow path of the first to third embodiments, the agglomerated particle group collides with a branching point and is forcibly divided. As a result, the amount of the mixture can be reduced even in a reduced pressure environment.

[Addition of linear motor mechanism]
The linear motor mechanism for accelerating or decelerating the mixture in the flow path as shown in FIG. 5 (h) is effective not only for the mixing flow path but also for the divided flow path and the conveyance path. A plurality of electrodes or electromagnets are arranged at predetermined intervals on one or both sides of the flow path, and each electrode or electromagnet is driven out of phase to generate a moving electric field or a moving magnetic field, which is mixed by electrophoresis or magnetic force. Accelerate or decelerate.

  For example, this function can also be realized by using a three-phase alternating current whose phase is shifted by 120 degrees. With such a configuration, it is possible to flow a mixture or mixture that is easily subjected to fluid resistance and is difficult to flow at a desired speed, and it is possible to realize highly accurate mixing between the mixtures in a short time. Such a configuration of the linear motor may be added to each of the divided flow path, the mixing flow path, and the aggregation flow path. For example, the linear motor is accelerated in the divided flow path, decelerated in the mixing flow path, and further, the aggregation flow path. By accelerating, it is possible to speed up the overall mixing process while maintaining the mixing accuracy.
