Summary of the Invention

Problems to be Solved by the Invention

[0005] In the conventional method of measuring the mixing state by inserting a probe into a fluid, it is necessary to once stop the operation of the mixing device and insert the probe into the fluid. With this method, it is difficult to measure the mixing state of the fluid in a short cycle, and it is difficult to detect the timing when the target mixing state is reached while sequentially measuring the mixing state and determine the optimal operating conditions.

[0006] The present invention has been made in view of the above problems, and aims to provide an operating condition presentation system, an operating condition presentation method, and a dispersion test system that can sequentially measure the dispersion state of a fluid being dispersed by a dispersion device and present the operating conditions of the dispersion device based on the measurement results of the dispersion state.

[0007] In this specification and in the claims, "dispersion" includes the meaning of mixing two or more fluids, and also includes the meaning of breaking up a solidified portion of a single type of fluid to make the fluid particle size uniform. Furthermore, "dispersion" also includes the uniformization of changes in the state of fluids when the state of the fluids changes chemically or physically, such as emulsification and gelation of multiple fluids. [Means for solving the problem]

[0008] To achieve the above objective, one of the present inventions is an operating condition presentation system that presents operating conditions for a dispersion device that disperses a fluid containing at least one of a powder and a liquid contained in a container, comprising: a test fluid which is a fluid containing luminescent particles; a test container which has at least a part of a permeable portion that transmits the luminescence of the luminescent particles; a test dispersion device which disperses the test fluid contained in the test container; an imaging device which images the luminescence of the luminescent particles that transmit through the permeable portion of the test container; and an operating condition presentation device which presents operating conditions based on the image obtained from the imaging device, wherein the operating condition presentation device comprises: a distribution state acquisition unit which acquires an image of the luminescent particles from the imaging device; a dispersion evaluation unit which evaluates the dispersion state of the test fluid based on the acquired distribution state; a database unit which constructs a database which includes the evaluation results of the dispersion evaluation unit and the trial operation conditions of the test dispersion device; and an operating condition presentation unit which presents operating conditions for dispersing a fluid equivalent to the test fluid in a container equivalent to the test container with a dispersion device equivalent to the test dispersion device based on the database.

[0009] To achieve the above objective, another method for presenting operating conditions according to the present invention is a method for presenting operating conditions for a dispersion device that disperses a fluid containing at least one of a powder and a liquid contained in a container, wherein a test fluid, which is a fluid containing luminescent particles, is contained in a test container having at least a portion of a permeable part that transmits the luminescence of the luminescent particles, the test fluid contained in the test container is dispersed by a test dispersion device, the luminescence of the luminescent particles transmitted through the permeable part of the test container is captured by an imaging device, the distribution state acquisition unit acquires an image of the luminescent particles from the imaging device and derives the distribution state of the luminescent particles, the dispersion evaluation unit evaluates the dispersion state of the test fluid based on the derived distribution state, the database unit constructs a database containing the evaluation results of the dispersion evaluation unit and the trial operation conditions of the test dispersion device, and based on the database, the operating condition presentation unit presents operating conditions for dispersing a fluid equivalent to the test fluid in a container equivalent to the test container using a dispersion device equivalent to the test dispersion device.

[0010] To achieve the above objective, another dispersion test system of the present invention comprises: luminescent particles added to a fluid to form a test fluid; a test container having at least a portion of a permeable section that transmits the light emitted from the luminescent particles; a test dispersion device for dispersing the test fluid contained in the test container; and an imaging device for imaging the light emitted from the luminescent particles that transmit through the permeable section of the test container. [Effects of the Invention]

[0011] According to the present invention, the dispersion state of a fluid can be measured sequentially and non-contact without stopping the dispersion device. Furthermore, by accumulating the measurement results, it is possible to provide operating conditions for the dispersion device that enable efficient fluid dispersion.

[Modes for carrying out the invention]

[0013] The following describes embodiments of the operating condition presentation system, operating condition presentation method, and distributed test system according to the present invention with reference to the drawings. The following embodiments are provided as examples to illustrate the present invention and are not intended to limit it. For example, the shapes, structures, materials, components, relative positional relationships, connection states, numerical values, mathematical formulas, the content of each stage in the method, and the order of each stage shown in the following embodiments are examples and may include content not described below. Geometric expressions such as parallel and orthogonal may be used, but these expressions do not indicate mathematical rigor and include substantially acceptable errors and deviations. Similarly, expressions such as simultaneous and identical also include substantially acceptable ranges.

[0014] Furthermore, the drawings are schematic diagrams that have been appropriately emphasized, omitted, or had their proportions adjusted to illustrate the present invention, and therefore differ from the actual shape, positional relationships, and proportions. Also, the X, Y, and Z axes shown in the drawings represent orthogonal coordinates arbitrarily set for the purpose of explaining the drawings. In other words, the Z axis is not necessarily an axis along the vertical direction, and the X and Y axes are not necessarily located in the horizontal plane.

[0015] Furthermore, in the following, multiple inventions may be described comprehensively as a single embodiment. Also, some of the content described below is described as an optional component relating to the present invention.

[0016] FIG. 1 is a perspective view showing an operation condition presentation system 100. FIG. 2 is a side view showing a test dispersion device 112. Note that FIGS. 1 and 2 are drawn with each device concentrated in order to explain the operation condition presentation system 100, but the distances between the devices shown in FIGS. 1 and 2 do not reflect the actual distances. The operation condition presentation system 100 is a system for presenting operation conditions for a dispersion device that disperses a fluid in a container, and includes a dispersion test system 110 and an operation condition presentation device 150.

[0017] The fluid includes at least one of powder and liquid, and may include gas. Also, emulsified and gelled substances are included in the fluid.

[0018] The shape, structure, size, etc. of the container used in actual operation are not particularly limited. In the case of this embodiment, a bottomed cylindrical container with a lid that can enclose a fluid is assumed as the container used in actual operation, and a test container 111 having the same shape as the assumed container is selected.

[0019] As the dispersion device, a device used in actual operation is assumed. The dispersion device may be of the same type as the test dispersion device 112 described later, or some or all of the specifications may be different. The method of dispersing the fluid by the dispersion device is not particularly limited, and for example, a fluid contained in a container may be stirred and dispersed by rotating an impeller inserted from above. In the case of this embodiment, as the dispersion device, a device that rotates a tilted sealable container around an axis intersecting the tilted axis and stirs and disperses the fluid enclosed in the container is assumed. The test dispersion device 112 will be described later.

[0020] The operation conditions are the conditions until the fluid contained in the container reaches a desired dispersion state. The parameters of the operation conditions vary depending on the dispersion device and are not limited. Examples of the parameters of the operation conditions include, for example, the volume of the container, the volume of the fluid with respect to the volume of the container (filling rate), the rotation speed, the rotation time, the number of rotations, the inclination of the container, and the like.

[0021] The dispersion test system 110 is a system that can realize operations of the same type or similar to the operation of dispersing an actual fluid, and is a system for obtaining a test operation condition for presenting the operation conditions used in actual operation. In the case of this embodiment, the dispersion test system 110 includes luminescent particles, a test container 111, a test dispersion device 112, and an imaging device 113. In the case of this embodiment, the dispersion test system 110 includes an irradiation device 114 and a synchronization device 115.

[0022] The luminescent particles are particles that are added to a fluid to be dispersed in actual operation or a fluid similar thereto to form a test fluid, and are self-luminescent particles. The type of the luminescent particles is not particularly limited, and for example, phosphorescent particles that accumulate light and self-luminesce for a predetermined time can be exemplified. In the case of this embodiment, the luminescent particles are so-called fluorescent particles that absorb light of a first wavelength irradiated from the irradiation device 114 as excitation light and emit light of a second wavelength different from the first wavelength. The first wavelength and the second wavelength are not particularly limited, but the first wavelength, which is excitation light, is preferably a wavelength that cannot be imaged by the imaging device 113, for example, a wavelength in the ultraviolet region (400 nm or less), and the second wavelength is preferably a wavelength that can be imaged by the imaging device 113, for example, a wavelength in the visible light region or more (450 nm or more) (including wavelengths in the infrared region). According to this, an image of the luminescent particles can be captured by the imaging device 113 based on the light of the second wavelength without being affected by the test container 111 or the light of the first wavelength reflected by the fluid.

[0023] The test container 111 is a container having the same internal shape and the same size as the container used in actual operation, or a similar internal shape and a similar size, and is a container provided with at least a part of a transmission portion that transmits light of a second wavelength in the visible light region or more emitted by the luminescent particles. In the case of this embodiment, the test container 111 is a glass container that functions as a transmission portion as a whole, and the test fluid can be taken in and out by opening the lid, and it becomes a sealed container in which the test fluid does not leak out by closing the lid.

[0024] The test dispersion device 112 is a device for dispersing the test fluid contained in the test container 111, and is the same as or similar to the dispersion device used to disperse fluid in actual operation. The method of dispersing the fluid in the test dispersion device 112 is not particularly limited, and examples include a method of dispersing the test fluid by rotating an impeller in the fluid, or a method of dispersing the contained test fluid by rotating a container with fixed blades or ribs inside while it is tilted. In this embodiment, the test dispersion device 112 is a device for dispersing the sealed test fluid by rotating the test container 111, which is held in a tilted position, around a rotation axis 102 that intersects the tilt axis, and comprises a container holding means 121, a rotation driving means 122, and a rotation shaft body 123. The arc-shaped arrows in Figure 1 indicate the direction of rotation of the test container 111.

[0025] The container holding means 121 is a mechanism that holds the inner bottom surface of the test container 111 in an inclined state with respect to the horizontal plane. In this embodiment, since the bottom surface and the inner circumferential surface of the test container are perpendicular to each other, the inner circumferential surface is also inclined with respect to the vertical line, similar to the bottom surface. The method of holding the container with the container holding means 121 is not particularly limited, but in this embodiment, the container holding means 121 holds the bottom and lid of the test container 111 by sandwiching them, and holds the test container 111, which rotates inclined state with respect to the rotation axis 102 located in the horizontal plane, so as not to shift.

[0026] The rotational drive means 122 is a mechanism that rotates the test container 111, which is held together with the container holding means 121, and is equipped with a motor as a drive source and a transmission mechanism that transmits the driving force of the motor to the rotating shaft.

[0027] The rotating shaft 123 is a member that extends along a horizontal plane and rotates around a rotation axis 102 that is included in the horizontal plane, and rotates together with the test container 111 with the container holding means 121 attached to its tip tilted with respect to the horizontal plane. The inclination θ of the test container 111 with respect to the rotating shaft 123 is one of the parameters of the operating conditions of the test dispersion device 112.

[0028] The imaging device 113 is a device that images the light emitted by light-emitting particles passing through the transparent portion of the test container 111, and includes an optical system and an image sensor that digitally acquires the image formed by the optical system as an image. In this embodiment, the imaging device 113 is a so-called digital still camera or digital video camera that can image light of the second wavelength and output it as an image. The settings of the imaging device 113 are not particularly limited, but a setting that provides a resolution sufficient to confirm a single light-emitting particle is preferred. Furthermore, the field of view in the setting is preferably one that allows for the imaging of 100 or more light-emitting particles that can be confirmed as a single particle in one image (one frame) when imaging the test fluid in the desired dispersion state.

[0029] The irradiation device 114 is a device that irradiates light containing the first wavelength into the transparent portion of the test container 111, and towards the entire field of view of the imaging device 113. It is preferable that the irradiation device 114 irradiates light that does not contain the second wavelength. In this embodiment, the irradiation device 114 irradiates light in a narrow wavelength range that includes the first wavelength, such as from an LED (Light Emitting Diode).

[0030] The synchronization device 115 synchronizes the rotation of the test container 111 in the test dispersion device 112 with the imaging timing of the imaging device 113, thereby capturing images of the test fluid inside the test container 111 in the same orientation. The synchronization device 115 is not particularly limited, and if the rotational drive means 122 is equipped with a servo motor, it may acquire information about the motor's rotation from a servo amplifier or servo controller and control the imaging device 113 based on that information. In this embodiment, the synchronization device 115 includes a rotating plate 116 and a photoelectric sensor 117, as shown in Figure 3.

[0031] The rotating plate 116 is a disc that extends in a direction perpendicular to the axis of rotation of the rotating shaft 123, and is attached to the rotating shaft 123 such that its central axis coincides with the axis of rotation 102 of the rotating shaft 123. A notch 103 is provided in a part of the outer edge of the rotating plate 116. The rotating plate 116 rotates together with the rotation of the rotating shaft 123, and the notch 103 rotates around the rotating shaft 123 with the same period as the rotating shaft 123, that is, with the same period as the test container 111.

[0032] The photoelectric sensor 117 is a sensor that can detect the notch of the rotating plate 116 based on light. In this embodiment, the photoelectric sensor 117 is a reflective type photoelectric sensor 117, and outputs an ON signal when it detects the rotating plate 116, and an OFF signal when it does not detect the rotating plate 116, i.e., when it detects the notch 103. The photoelectric sensor 117 may also be a transmissive type. The synchronization device 115 detects the notch, which is rotating with the rotating shaft 123, at a certain location, and outputs a signal to the imaging device 113 that allows the imaging device 113 to take an image at the timing of detection, in this embodiment, the timing of obtaining an OFF signal from the photoelectric sensor 117.

[0033] Figure 4 is a block diagram showing the functional configuration of the operating condition presentation device. As shown in the figure, the operating condition presentation device 150 disperses a test fluid under multiple types of test operating conditions, acquires multiple images of fluorescent particles showing the dispersion state of the test fluid including the dispersion process, evaluates the dispersion state of the test fluid from the acquired images, and stores the evaluation results of the trial operating conditions and dispersion state in a database. The operating condition presentation device 150 is a computer equipped with a processor, and the processing units realized by having the processor execute a program include a distribution state acquisition unit 151, a dispersion evaluation unit 152, a database unit 153, and an operating condition presentation unit 155. In this embodiment, the operating condition presentation device 150 includes a trial operating condition acquisition unit 154.

[0034] The distribution state acquisition unit 151 acquires images of luminescent particles from the imaging device 113, for example, as shown in Figure 5. Figure 5 shows the distribution state of luminescent particles when the test container 111 shown in Figure 2 is rotated N times around the rotating shaft 123. The images acquired by the distribution state acquisition unit 151 include only images of luminescent particles in a two-dimensional region in contact with the permeable portion of the test fluid sealed in the test container 111, or near the permeable portion. Note that each image shown in Figure 5 shows an overall image of the test container 111, which is entirely a permeable portion. The inventors have found that the distribution of luminescent particles present in a part of the surface layer of the test fluid reflects the dispersion state of the entire test fluid. Based on this finding, the inventors have discovered that appropriate operating conditions can be presented by acquiring and accumulating the dispersion state of the test fluid without contact with the test fluid. Furthermore, because the dispersion state can be acquired without contact, it is possible to sequentially acquire changes in the dispersion state of the test fluid over time in short cycles, and appropriate operating conditions can be presented with high accuracy.

[0035] In this embodiment, as shown in Figure 6, the distribution state acquisition unit 151 extracts a predetermined range from the image obtained from the imaging device 113, and extracts the number of independent light-emitting regions from the extracted region, or the coordinates of representative points of the independent light-emitting regions relative to the extracted region, as the distribution state. A light-emitting region is a region in the image corresponding to a single light-emitting particle. The size of the region to be extracted is not particularly limited, but for example, a size that captures 100 to 3000 light-emitting regions when the test fluid is in a desired dispersion state is preferred. Specifically, for example, any region (including squares) between 10,000 pixels and 1,000,000 pixels can be used as an example of the region to be extracted.

[0036] In this embodiment, the distribution state acquisition unit 151 extracts a region containing 100 or more luminescent regions when the test fluid reaches a desired dispersion state, performs image analysis, and calculates the coordinates of the centroid of each luminescent region, using it as a representative point where the luminescent particles exist. The distribution state acquisition unit 151 also acquires images of the luminescent particles from the imaging device 113 in the same orientation of the rotating test container 111.

[0037] The method for acquiring images of the test container 111 in the same orientation is not particularly limited. For example, if the imaging device 113 is a digital video camera that acquires multiple images per second, the distribution state acquisition unit 151 may pick up and acquire only frames that capture the inside of the test container 111 in a predetermined orientation. In this embodiment, since the imaging device 113 captures the test container 111 when it is in the same orientation by the synchronization device 115, the images acquired by the distribution state acquisition unit 151 from the imaging device 113 correspond to images of the luminescent particles in the same orientation. By acquiring images of luminescent particles acquired from the test container 111 in the same orientation over time, as shown in Figure 5, it becomes possible to stably observe the changes in the dispersion state of the test fluid over time. Furthermore, by acquiring images of the inside of the test container 111 in the same orientation under different trial conditions, it becomes possible to accurately compare different trial conditions.

[0038] The distribution state acquisition unit 151 calculates an evaluation value indicating the distribution state of the luminescent particles by performing spatial analysis on the coordinates representing the centroid of each luminescent region within a predetermined area. Multiple spatial analysis methods exist, and any of them may be used to calculate the evaluation value, but in this embodiment, the distribution state acquisition unit 151 calculates the evaluation value indicating the distribution state of the luminescent particles using the K-function method. Alternatively, an L-function, which has a certain relationship with the K-function, may be used.

[0039] Specifically, the K-function K(h) is calculated using Equation 1 below.

[0040]

number

[0041] In this embodiment, the distribution state acquisition unit 151 calculates a real-valued area As as an evaluation value, which is the value obtained by integrating K(h) from h=0 to h=a predetermined distance (for example, a distance of 50 pixels).

[0042] The dispersion evaluation unit 152 evaluates the dispersion state of the test fluid based on the distribution state acquired by the distribution state acquisition unit 151. The evaluation method of the dispersion evaluation unit 152 is not particularly limited; for example, the number of luminescent regions within a predetermined area may be determined by a threshold, and if it is above the predetermined threshold, it may be evaluated that the desired dispersion state has been reached. In this embodiment, the dispersion evaluation unit 152 evaluates the dispersion state by comparing the evaluation value calculated by the distribution state acquisition unit 151 with the expected value. The expected value is expressed as E[K(h)]=πh^2 (^ represents exponentiation)...Equation 2. Specifically, the dispersion evaluation unit 152 evaluates the dispersion state of the test fluid based on the ratio of the evaluation value to the expected value area S, which is the value obtained by integrating E[K(h)] from h=0 to h=a predetermined distance (for example, a distance of 50 pixels). For example, if As / S is less than 1, it is evaluated that the desired dispersion state has been reached.

[0043] The database unit 153 constructs a database containing the evaluation results from the dispersion evaluation unit 152 and the trial operation conditions of the test dispersion device 112, and stores it in the storage device 120. For example, the trial operation conditions include the type of fluid constituting the test fluid (substance name, particle size, specific gravity, viscosity, etc.), the internal shape of the test container 111, the volume of the test fluid relative to the internal volume of the test container 111 (filling rate), the inclination angle of the test container 111 (θ shown in Figure 2), the rotation speed of the test container 111, and the number of rotations of the test container 111 (N shown in Figure 5). Some of the trial operation conditions may be acquired by the trial operation condition acquisition unit 154 from the test dispersion device 112, or the trial operation condition acquisition unit 154 may acquire trial operation conditions entered by an operator or the like via the interface 118. In addition, there may be multiple types of fluids. In this embodiment, the database unit 153 acquires evaluation results (e.g., As / S) from the dispersion evaluation unit 152 at predetermined rotation counts and constructs the database.

[0044] The operating condition presentation unit 155 acquires some of the operating conditions input by the operator via the interface 118, such as the type of fluid that makes up the fluid used in actual operation, the internal shape of the container, and the volume of the fluid relative to the internal volume of the container (filling rate). Based on the database constructed by the database unit 153, it extracts equivalent trial operation conditions as operating conditions and presents them to the operator. The presented operating conditions include, for example, the inclination angle of the container, the rotation speed of the container, the change in the evaluation value with respect to the number of rotations of the container, and the number of rotations when As / S becomes less than 1. In this embodiment, the operating conditions are presented to the operator via the display device 119.

[0045] According to the operating condition presentation system, operating condition presentation method, and dispersion test system of this embodiment, the dispersion state of a test fluid can be measured and evaluated non-contact without stopping the dispersion device. Therefore, the dispersion state can be evaluated sequentially at predetermined intervals from the initial stage of dispersion operation, and the time (number of rotations) to reach the desired dispersion state can be obtained with high accuracy (e.g., every rotation). Furthermore, by creating a database of dispersion evaluation and trial operation conditions, appropriate operating conditions for obtaining the desired dispersion state can be presented when dispersing equivalent fluids with equivalent dispersion devices.

[0046] Furthermore, the dispersion state can be evaluated non-contact. This eliminates the need to open a sealed container containing the fluid each time a measurement is taken, thus preventing fluid degradation due to oxidation, etc., and allowing for accurate and continuous evaluation of the dispersion state.

[0047] It should be noted that the present invention is not limited to the embodiments described above. For example, other embodiments of the present invention may be realized by arbitrarily combining the components described herein, or by excluding some of the components. Furthermore, modifications obtained by applying various modifications to the above embodiments that a person skilled in the art could conceive of without departing from the spirit of the present invention, that is, the meaning indicated by the wording in the claims, are also included in the present invention.

[0048] For example, the spatial analysis performed by the distribution state acquisition unit 151 may be carried out not only using the K-function method, but also using methods such as the partitioning method or the nearest neighbor distance method.

[0049] Furthermore, while we used the integral values ​​of the obtained K-function within a predetermined range for evaluation, we are not limited to this, and any appropriate evaluation based on differences in spatial analysis methods is acceptable. For example, the dispersion state can be evaluated based on the magnitude of the range of h in which the curve shown by the obtained K-function is lower than the curve showing the expected value. [Industrial applicability]
