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 distributed test system 110 includes an irradiation device 114 and a synchronization device 115.

Luminescent particles are particles that are added to a fluid to be dispersed in actual operation or a similar fluid to form a test fluid, and are particles that emit light by themselves. Although the type of luminescent particles is not particularly limited, for example, luminescent particles that accumulate light and emit light for a predetermined period of 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 emitted 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 the 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), 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 above (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 light of the first wavelength reflected by the test container 111 or the fluid.

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 similar size, and has a shape and size that exceeds the visible light range emitted by the luminescent particles. The container is at least partially equipped with a transmitting portion that transmits light of a second wavelength. In the case of this embodiment, the test container 111 is a glass container that functions entirely as a transmission part, and the test fluid can be taken in and taken out by opening the lid, and the test fluid can be taken out by closing the lid. Do not store in an airtight container.

The test dispersion device 112 is a device that disperses the test fluid contained in the test container 111, and is the same as or similar to the dispersion device that disperses the fluid in actual operation. The method of dispersing the fluid in the test dispersion device 112 is not particularly limited, and includes a method of dispersing the test fluid by rotating an impeller in the fluid, and a method of dispersing the test fluid by rotating an impeller in the fluid, and a method of dispersing the test fluid by tilting a container equipped with fixed blades or ribs inside. For example, a method of dispersing the contained test fluid by rotating the test fluid in the same state can be exemplified. In the case of this embodiment, the test dispersion device 112 is a device that rotates the test container 111 held in a tilted state around a rotation axis 102 that intersects the tilted axis to disperse the sealed test fluid. It includes a holding means 121, a rotation driving means 122, and a rotating shaft body 123. Note that the arc-shaped arrow in FIG. 1 indicates the rotation direction of the test container 111.

The container holding means 121 is a mechanism that holds the inner bottom surface of the test container 111 in a state inclined with respect to the horizontal plane. In the case of this embodiment, since the bottom surface and the inner peripheral surface of the test container are perpendicular to each other, the inner peripheral surface is also inclined with respect to the vertical line like the bottom surface. The holding method of the container holding means 121 is not particularly limited, but in the case of the present embodiment, the container holding means 121 holds the test container 111 by sandwiching the bottom and the lid, and holds the test container 111 in a horizontal plane. The test container 111, which rotates while being tilted with respect to the rotating shaft 102 disposed in the test container 102, is held so as not to shift.

The rotation drive means 122 is a mechanism for rotating the test container 111 held together with the container holding means 121, and includes a motor as a drive source and a transmission mechanism that transmits the driving force of the motor to the rotating shaft.

The rotating shaft body 123 is a member that extends along a horizontal plane and rotates around the rotating shaft 102 included in the horizontal plane, and the rotating shaft body 123 is a member that rotates around the rotating shaft 102 that extends along a horizontal plane and is included in the horizontal plane. It is a rotating member. The inclination θ of the test container 111 with respect to the rotating shaft body 123 is one of the parameters of the operating conditions of the test dispersion device 112.

The imaging device 113 is a device that images the light emitted from the luminescent particles that passes through the transmission part of the test container 111, and includes an optical system and an imaging element that digitally acquires the image formed by the optical system. In the case of 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 setting of the imaging device 113 is not particularly limited, but it is preferably set to a resolution that allows one luminescent particle to be confirmed. In addition, the angle of view in the setting is preferably such that 100 or more luminescent particles that can be confirmed as a single particle can be imaged in one image (one frame) when the test fluid in the desired dispersed state is imaged.

The irradiation device 114 is a device that irradiates light including the first wavelength toward the entire viewing angle of the imaging device 113 in the transmitting portion of the test container 111 . It is preferable that the irradiation device 114 irradiates light that does not include the second wavelength. In the case of this embodiment, the irradiation device 114 irradiates light in a narrow wavelength range including the first wavelength, such as an LED (Light Emitting Diode).

The synchronizer 115 is a device that synchronizes the rotation of the test container 111 in the test dispersion device 112 and the imaging timing of the imaging device 113 to capture images of the test fluid in the test container 111 in the same posture. The synchronizer 115 is not particularly limited, and when the rotation drive means 122 includes a servo motor, the synchronizer 115 acquires information regarding the rotation of the motor from a servo amplifier or a servo controller, and controls the imaging device 113 based on the information. You may. In the case of this embodiment, the synchronizer 115 includes a rotating plate 116 and a photoelectric sensor 117, as shown in FIG.

The rotating plate 116 is a disk that extends in a direction perpendicular to the rotation axis of the rotating shaft body 123, and is attached to the rotating shaft body 123 so that its central axis coincides with the rotation axis 102 of the rotating shaft body 123. A notch 103 is provided in a part of the outer peripheral edge of the rotating plate 116. The rotary plate 116 rotates with the rotation of the rotary shaft body 123, and the notch portion 103 rotates around the rotary shaft body 123 at the same period as the rotary shaft body 123, that is, the same period as the test container 111.

The photoelectric sensor 117 is a sensor that can detect the notch portion of the rotating plate 116 based on light. In the case of this embodiment, the photoelectric sensor 117 is a reflective type photoelectric sensor 117, and outputs an ON signal when the rotary plate 116 is detected, and an ON signal when the rotary plate 116 is not detected, that is, the notch 103 is detected. When it is on, it outputs an OFF signal. Note that the photoelectric sensor 117 may be of a transmission type. The synchronizer 115 detects the notch part that the photoelectric sensor 117 rotates with the rotating shaft body 123 at a certain location, and the timing of the detection, in the case of this embodiment, acquires an OFF signal from the photoelectric sensor 117. A signal that allows the imaging device 113 to take an image is output to the imaging device 113 at a certain timing.

FIG. 4 is a block diagram showing the functional configuration of the driving condition presentation device. As shown in the figure, the operating condition presentation device 150 disperses the test fluid under a plurality of types of test operating conditions and obtains a plurality of images of fluorescent particles showing the dispersion state of the test fluid including the dispersion process. This device evaluates the dispersion state of the test fluid from images and stores test run conditions and dispersion state evaluation results as a database. The operating condition presentation device 150 is a computer equipped with a processor, and includes a distribution state acquisition section 151, a dispersion evaluation section 152, a database section 153, and an operating condition acquisition section 151, a dispersion evaluation section 152, a database section 153, and a processing section realized by causing the processor to execute a program. A presentation section 155 is provided. In the case of this embodiment, the driving condition presentation device 150 includes a test driving condition acquisition section 154.

The distribution state acquisition unit 151 acquires, for example, an image of luminescent particles as shown in FIG. 5 from the imaging device 113. FIG. 5 shows the distribution state of luminescent particles when the test container 111 shown in FIG. 2 is rotated N times around the rotating shaft body 123. The image acquired by the distribution state acquisition unit 151 includes only an image of the luminescent particles in a portion in contact with the transmission part of the test fluid sealed in the test container 111 or in a two-dimensional area in the vicinity of the transmission part. Note that each image shown in FIG. 5 shows the entire image of the test container 111, which is the entire transparent part. The inventor has discovered that the distribution of luminescent particles present in a portion of the surface layer of the test fluid reflects the state of dispersion of the entire test fluid. Based on this knowledge, the inventor has found that appropriate operating conditions can be presented by acquiring and accumulating the dispersion state of the test fluid without contacting the test fluid. In addition, since the dispersion state can be obtained without contact, it has been found that changes in the dispersion state of the test fluid over time can be sequentially obtained in short cycles, making it possible to present appropriate operating conditions with high accuracy. .

In the case of this embodiment, as shown in FIG. 6, the distribution state acquisition unit 151 cuts out a predetermined range from the image obtained from the imaging device 113, and calculates the number of independent light emitting regions from the cut out area, or The coordinates of each representative point of an independent light emitting region with respect to the cut out region are extracted as a distribution state. A luminescent region is an area in an image corresponding to one luminescent particle. The size of the region to be cut out is not particularly limited, but preferably has a size that allows 100 or more and 3000 or less light-emitting regions to be captured when the test fluid is in a desired dispersed state. Specifically, for example, any region (including squares) of 10,000 pixels or more and 1 million pixels or less can be exemplified as the region to be cut out.

In the case of this embodiment, the distribution state acquisition unit 151 cuts out a region where 100 or more light emitting regions exist when the test fluid reaches a desired dispersion state, performs image analysis, and calculates the center of gravity of each light emitting region. The coordinates are calculated using as the representative point where the luminescent particle exists. Further, the distribution state acquisition unit 151 acquires an image of the luminescent particles in the same posture of the rotating test container 111 from the imaging device 113.

The method of acquiring images of the test container 111 in the same posture is not particularly limited. For example, if the imaging device 113 is a digital video camera that acquires multiple images per second, distribution state acquisition may be used. The unit 151 may pick up and acquire only frames that image the inside of the test container 111 in a predetermined posture. In the case of this embodiment, since the imaging device 113 images the test container 111 in the same posture by the synchronization device 115, the image that the distribution state acquisition unit 151 acquires from the imaging device 113 is This corresponds to images of luminescent particles in the same posture. By acquiring images of the luminescent particles from the test container 111 in the same posture over time as shown in FIG. 5, it is possible to stably observe changes in the dispersion state of the test fluid over time. becomes. Further, by acquiring images of the inside of the test container 111 in the same posture even under different test run conditions, it becomes possible to accurately compare different test run conditions.

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 indicating the center of gravity of each luminescent region within a predetermined region. There are multiple spatial analysis methods, and any of them may be used to calculate the evaluation value, but in the case of this embodiment, the distribution state acquisition unit 151 indicates the distribution state of luminescent particles using the K-function method. Calculate the evaluation value. Note that an L function having a certain relationship with the K-function may be used.

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

h: Distance from the representative point n: Total number of representative points within a given area λ: n/a
a: Area of the predetermined region.

In the case of the present embodiment, the distribution state acquisition unit 151 uses the real value area As, which is the value obtained by integrating K(h) from h=0 to h=predetermined distance (for example, a distance of 50 pixels), as the evaluation value. calculate.

The dispersion evaluation section 152 evaluates the dispersion state of the test fluid based on the distribution state acquired by the distribution state acquisition section 151. The evaluation method of the dispersion evaluation unit 152 is not particularly limited. For example, the number of light-emitting regions within a predetermined region is determined by a threshold value, and if the number is equal to or greater than the predetermined threshold value, it is evaluated that a desired dispersion state has been reached. Good too. In the case of 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 by E[K(h)]=πh^2 (^ represents a power)...Equation 2. Specifically, the variance evaluation unit calculates the variance evaluation unit 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). 152 evaluates the dispersion state of the test fluid. For example, if As/S becomes less than 1, it is evaluated that a desired dispersion state has been reached.

The database unit 153 constructs a database including the evaluation results of the distribution evaluation unit 152 and the trial run conditions of the test distribution device 112, and stores it in the storage device 120. For example, the test run 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 ratio), These include the inclination angle of the test container 111 (θ shown in FIG. 2), the rotation speed of the test container 111, the number of rotations of the test container 111 (N shown in FIG. 5), etc. Some of the test run conditions may be acquired by the test run condition acquisition unit 154 from the test distribution device 112, or the test run condition acquisition unit 154 may acquire test run conditions input by an operator or the like via the interface 118. I don't mind. Furthermore, there may be multiple types of fluid. In the case of this embodiment, the database unit 153 acquires evaluation results (for example, As/S) from the dispersion evaluation unit 152 every predetermined number of rotations, and constructs a database.

The operating condition presentation unit 155 displays some of the operating conditions input by an operator or the like via the interface 118, such as the type of fluid constituting the fluid used in the actual operation, the internal shape of the container, and the ratio of the fluid to the internal volume of the container. The volume (filling rate) is acquired, and based on the database constructed by the database unit 153, equivalent test run conditions are extracted as operating conditions and presented to the operator. The operating conditions presented include, for example, the tilt angle of the container, the rotation speed of the container, the change in evaluation value with respect to the number of rotations of the container, the number of rotations when As/S becomes less than 1, and the like. In the case of this embodiment, the operating conditions are presented to the operator etc. via the display device 119.

According to the operating condition presentation system, operating condition presentation method, and dispersion test system according to the present embodiment, the dispersion state of the test fluid can be measured and evaluated in a non-contact manner without stopping the dispersion device. Therefore, the dispersion state can be sequentially evaluated at predetermined intervals from the initial stage of the dispersion operation, and the time (number of rotations) at which the desired dispersion state is reached can be obtained with high precision (for example, every rotation). Furthermore, by creating a database of dispersion evaluation and test run conditions, it is possible to present appropriate operating conditions to obtain a desired dispersion state when dispersing the same fluid using the same dispersion device.

Furthermore, the dispersion state can be evaluated without contact. As a result, it is not necessary to open the closed container containing the fluid every time a measurement is performed, so the fluid does not deteriorate due to oxidation or the like, and accurate evaluation of the dispersion state can be carried out intermittently.

Note that the present invention is not limited to the above embodiments. For example, the embodiments of the present invention may be realized by arbitrarily combining the components described in this specification or by excluding some of the components. The present invention also includes modifications obtained by making various modifications to the above-described embodiments that a person skilled in the art can conceive without departing from the gist of the present invention, that is, the meaning of the words written in the claims. It will be done.

For example, the spatial analysis performed by the distribution state acquisition unit 151 may be performed using not only the K-function method but also the partition method, nearest neighbor distance method, or the like.

Further, although the integral value of the obtained K-function in a predetermined range was used for evaluation, the evaluation is not limited to this, and may be appropriately evaluated based on the difference in the spatial analysis method. For example, the dispersion state may be evaluated based on the size of the range of h in which the curve represented by the obtained K-function is lower than the curve representing the expected value.
