Detailed Description
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings illustrate, by way of example, specific embodiments in which the invention may be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments according to the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
The terms to which the present invention relates will be explained first. "metalworking fluid" refers to a fluid used in metalworking processes that may have lubricating, cooling, flushing or rust inhibiting functions and generally includes base oils and additives.
The inventor finds that the state of the metal working fluid cannot be comprehensively reflected only by measuring the single index of the metal working fluid, and pollutants in the metal working fluid interfere with the performance of detection equipment, so that the detection result has large error, the metal working fluid cannot be directly analyzed by a computer to automatically adjust the metal working fluid, and manual intervention and judgment are needed.
In view of the above problems, the present invention provides a detection apparatus configured as a fluid, by which a component separation process can be performed on the obtained fluid to remove a specified contaminant in the fluid, thereby reducing the influence of the contaminant on a subsequent detection. The detection device can also detect multiple parameters of the metal working fluid before and after the component separation treatment, determine the use state of the fluid based on the detection result, and further determine the corresponding adjustment of the metal working fluid, such as stock solution supplement, water supplement, fluid replacement, additive supplement and the like.
FIG. 1 is a block diagram of a detecting device according to an embodiment of the present invention.
The detection apparatus 100 includes a separation module 110, a detection module 120, an analysis module 130, and a control module 140. The operation of the detection device is explained below.
The separation module 110 is configured to perform a component separation operation on a fluid to remove a specified component of the fluid. For example, the separation module 110 may remove components in the fluid by filtering the fluid with different filtering precisions, such as removing solid particles by a first filtering method and removing oil by a second filtering method. It will be appreciated that the first filtering regime corresponds to a first filtering accuracy and the second filtering regime corresponds to a second filtering accuracy, wherein the first filtering accuracy is lower than the second filtering accuracy. In other embodiments, the separation module 110 may also perform centrifugation, reverse osmosis, and/or electrodialysis on the fluid to achieve component separation of the fluid.
The detection module 120 is configured to perform a specified detection on the fluid to output a detection result. For example, the detection module 120 may be used to detect a condition parameter of the fluid, such as at least one of: pH, conductivity, refractive index, specified ion concentration, viscosity, density, turbidity, absorbance, particle count, liquid surface tension, acoustic transmission (sound velocity), and the like. It is understood that the detection module 120 may also detect the fluid by XRF, infrared spectroscopy, and the like. In this embodiment, the detection module 120 outputs a first detection result and a second detection result, wherein the first detection result corresponds to the fluid without component separation, and the second detection result corresponds to the fluid with component separation.
After the analysis module 130 obtains the first and second detection results output by the detection module 120, the difference between the two results is determined to generate the operation signal. Specifically, the analysis module 130 can determine the state parameter of the fluid according to the difference between the two detection results, and then perform a targeted adjustment according to the state of the fluid.
After the control module 140 obtains the operation signal, the specified operation is performed on the fluid through the corresponding sub-module. For example, when the operation signal indicates that a specified amount of additive is to be added to the fluid, the control module 140 controls the corresponding sub-module (e.g., valve) to add the corresponding additive to the fluid based on the operation signal, thereby achieving the adjustment of the state of the fluid.
The following describes the detection method and the operation of the detection apparatus 100 according to the present invention by examples 1 and 2, respectively.
Example 1: the level of miscellaneous oil in a fluid (e.g., a cleaning agent) is detected.
During operation of the cleaning machine, various impurities may be incorporated into the cleaning agent, which may include emulsified miscellaneous oils and/or water-soluble impurities. The inventor finds out through research that the greatest influence on the cleaning effect is the content of the miscellaneous oil. In addition, due to the complex composition of water-soluble impurities, different substances have different influence degrees on the density, and the data obtained by testing the stock solution by using a densitometer only can have larger deviation.
Please refer to fig. 1 and 2, wherein fig. 2 is a flowchart illustrating a process of detecting miscellaneous oil according to an embodiment of the present invention.
Step S201: and obtaining the cleaning agent to be detected.
In this step, the cleaning agent in use may be accessed by an extraction module (not shown) as the cleaning agent to be tested. In this embodiment, the cleaning agent to be measured is the cleaning agent in use. It will be appreciated that the extraction module may be coupled to any location in the cleaning agent flow path, depending on the requirements of the application. In other embodiments, when the separating device is arranged directly in the flow path of the cleaning agent, the cleaning agent to be measured can also be directly accessed without the need for an extraction module.
Step S202: and obtaining the density of the cleaning agent to be detected.
In this step, the density of the cleaning agent to be detected is obtained by the detection module 120. For example, the detection module 120 may measure the cleaning agent to be measured directly or via a coupled density meter to determine the first density parameter D1 associated with the density of the cleaning agent to be measured.
Step S203: and (4) carrying out component separation on the cleaning agent to be detected to obtain the treated cleaning agent.
Specifically, in this step, the miscellaneous oil in the cleaning agent to be measured is filtered out (for example, by a filter membrane) by the separation module 110 to obtain a solution substantially not containing emulsified miscellaneous oil. It will be appreciated that by performing a filtered treatment, the amount of miscella in the solution may be below a specified threshold.
Step S204: the density of the treated cleaning agent is obtained.
In this step, the density D2 of the treated cleaning agent is obtained by the detection module 120. For example, the detection module 120 may measure the treated cleaning agent directly or may measure the treated cleaning agent via a coupled density meter to determine a second density parameter associated with the density of the treated cleaning agent.
Step S205: determining the content of the miscellaneous oil based on the first and second density parameters.
In this step, the analysis module 130 determines the content of the miscellaneous oil in the liquid to be measured according to the density parameters measured twice. Specifically, the corresponding content of the miscellaneous oil can be determined through a pre-calibrated working curve based on the difference D1-D2 between the first and second density parameters.
Step S206: and determining the adjustment operation of the cleaning agent based on the content of the miscellaneous oil.
In this step, the analysis module 130 may determine an adjustment operation signal for the cleaning agent being used based on the content of the miscellaneous oil. The control module 140 performs a specified operation on the fluid through the corresponding sub-module based on the adjustment operation signal. For example, when the adjustment signal indicates that the cleaning agent is to be replenished, the control module 140 controls the valve/pump/switch to replenish the cleaning agent currently being used, thereby adjusting the condition of the cleaning agent in the cleaning machine.
It will be appreciated that the order of execution of the steps described above may be varied as desired. For example, after step S201 is executed, step S203 may be directly executed without waiting for the execution result of step S202.
The method can effectively eliminate the influence of different water-soluble impurities on the densimeter. The difference in density is only related to the amount of miscellaneous oils in the cleaning agent.
Example 2: and detecting the content of solid particles and emulsified oil in the fluid.
The solid particles have the characteristics of large size and solid state, and the emulsified oil has the characteristic of microscopic liquid state and insolubility in water. Therefore, in the present embodiment, the solid particles are filtered with the first filtering precision, thereby reducing the number of the solid particles in the fluid; and filtering the emulsified oil with the second filtering precision, thereby reducing the content of the emulsified oil in the fluid. Due to the difference of the characteristics of the solid particles and the emulsified oil, when the solid particles and the emulsified oil exist in the stock solution at the same time, the solid particles need to be removed first, and then the emulsified oil needs to be removed.
FIG. 3a is a diagram of a detecting device according to another embodiment.
The detection apparatus 300 includes separation modules 310a and 310b, a detection module 320, an analysis module 330, and a control module 340. How the detecting device 300 works will be explained below.
The separation module 310a is configured to perform a component separation operation on the fluid to remove a specified component of the fluid. For example, the separation modules 310a and 310b may remove components in the fluid by filtering the fluid with different filtering precisions, such as removing solid particles in the fluid F1 by a first filtering manner to obtain the fluid F2, and removing oil in the fluid F2 by a second filtering manner to obtain the fluid F3. It will be appreciated that the first filtering regime corresponds to a first filtering accuracy and the second filtering regime corresponds to a second filtering accuracy, wherein the first filtering accuracy is lower than the second filtering accuracy. In other embodiments, the separation module may also perform centrifugation, reverse osmosis, and/or electrodialysis on the fluid to achieve component separation of the fluid.
The detection module 320 is configured to perform a specified detection on the fluid to output a detection result. For example, the detection module 320 may be configured to detect a status parameter of the fluids F1, F2, and F3, such as at least one of: pH, conductivity, refractive index, specified ion concentration, viscosity, density, turbidity, absorbance, particle count, liquid surface tension, acoustic transmission (sound velocity), and the like. It is understood that the detection module 320 may also detect the fluid by way of XRF, infrared light, etc. In the present embodiment, the detecting module 320 outputs first to fourth detection results, wherein the first and second detection results correspond to the first component, and the third and fourth detection results correspond to the second component.
After the analysis module 330 obtains the detection result output by the detection module 320, it will generate a corresponding operation signal according to the difference between the first and second detection results and the difference between the third and fourth detection results. For example, the analysis module 330 can determine the state parameter of the fluid according to the difference between the first and second detection results, and then perform a targeted adjustment according to the state of the fluid.
After the control module 340 obtains the operation signal, it will perform the specified operation on the fluid through the corresponding sub-module. For example, when the operation signal indicates that a specified amount of additive is to be added to the fluid, the control module 340 controls the corresponding sub-module (e.g., valve) to add the corresponding additive to the fluid based on the operation signal, thereby adjusting the state of the fluid.
FIG. 3b is a flow chart of fluid detection according to another embodiment of the present invention.
Step S301: and acquiring the fluid to be measured.
In this step, the fluid in use may be acquired by the extraction module as the fluid to be measured. It will be appreciated that the extraction module may be arranged at any location in the fluid flow path, depending on the requirements of the application. In other embodiments, when the separation modules 310a, 310b are arranged directly in the flow path of the cleaning agent, the cleaning agent to be tested can also be directly accessed without the need for an extraction module.
Step S302: the amount of solid particles in the fluid is obtained.
In this step, the amount of solid particles in the fluid may be reduced by the filtering action of the separation module 310a (e.g., the first filter). When the fluid F1 passes through the separation module 310a, the detection module 120 can obtain the pressure value P1 near the inlet and the pressure value P2 near the outlet of the separation module 310a, and further obtain the pressure difference between the inlet and the outlet of the separation module 310a as follows:
ΔP＝P1-P2
wherein Δ P will gradually increase as the solid particles are enriched in the separation module 310 a. The value of change in Δ P is related to the number of solid particles per unit volume in the fluid to be measured over a specified time period T.
Step S303: and determining to perform a first adjustment operation on the fluid to be measured based on the number of the solid particles.
Specifically, if Δ P is below a specified threshold for a time period T, it is considered stable and no operation is performed on the fluid; if the change in Δ P is greater than the specified threshold over the time period T, indicating that the number of solid particles per unit volume in the fluid is greater, a first adjustment operation needs to be performed on the fluid. In this embodiment, this means that the filtration system of the machine using the fluid is malfunctioning (failing to adequately filter the fluid).
Step S304: obtaining the content of emulsified oil in fluid
After the fluid F2 flowing out of the separation module 310a passes through the separation module 310b with higher filtering precision, the fluid F3 with lower/zero emulsified oil content can be obtained. The density ρ 1 of the fluid that has not yet flowed into the separation module 310b and the density ρ 2 of the fluid F3 flowing out of the separation module 310b can be obtained by the detection module 120, with the difference between the densities:
Δρ＝ρ1-ρ2
the absolute value of Δ ρ is related to the content of emulsified oil in the stock solution at the same temperature, and as the oil content increases, the absolute value of Δ ρ increases.
S305: and determining to perform a second adjustment operation on the fluid to be measured.
In this embodiment, when the absolute value of Δ ρ is within the specified range, it is considered that the content of emulsified oil is normal, and it is not necessary to adjust the content of emulsified oil in the fluid. When the absolute value of Δ ρ is outside the specified range (i.e., above the upper boundary value), additional chemicals and water are required to dilute the oil content; when the absolute value of Δ ρ is below the specified range, then the oil content needs to be increased by adding an oiliness additive.
It is understood that in another embodiment, the adjustment operation may be performed after the contents of the solid particles and the emulsified oil are obtained separately. In other words, the timing for performing the adjustment operation may be determined according to a specific application, that is, the fluid may be adjusted after obtaining one detection result (the flow in fig. 3 b), or the operation for adjusting the fluid may be determined by obtaining a plurality of detection results and considering the relationship between the components in the fluid to be measured or the influence between the detection operations. For example, when the amount of particulate matter detected is above a specified threshold, the alarm system or the filter system may be immediately notified to make an adjustment without waiting for further detection. For emulsified oils, the corresponding measure for excess oil content is dilution with water, but at the same time the concentration of other components will also decrease. Therefore, the method of diluting with water and then replenishing other components cannot be used here, because many chemicals are not added as raw liquids, but are replenished after being diluted with water, which leads to further reduction of the emulsified oil content, even below the lower limit value. As can be seen from the above, in this case, it is necessary to wait for the amounts of the other components to be measured before calculating the amount to be supplemented, i.e., the adjustment operation is performed after obtaining a plurality of measurement results.
In other embodiments, the detection module 320 may also obtain parameters of pH, conductivity, refractive index, specified ion concentration, viscosity, turbidity, absorbance, particle count, liquid surface tension, acoustic transmission (sound velocity), and the like of the fluid.
In practical application, emulsified oil components in the stock solution have a certain pollution effect on probes of devices such as a pH meter, a conductivity meter and the like (or multiple parameters), and if the stock solution is directly tested by the pH meter and the conductivity meter, the obtained data can have fluctuation and deviation in different degrees. The filtrate after passing through the ultrafiltration component does not contain emulsified oil components, the data measured by the pH meter and the conductivity meter can be more stable and accurate, and the system can give an accurate alarm signal according to the tiny abnormal fluctuation of the pH value and the conductivity value.
The above-described embodiments reduce the cost of testing for the company, i.e., do not require laboratory personnel to go to the site to take a sample before performing an off-line test. The embodiment reduces the feedback time of the detection result, reduces the detection frequency, can carry out multi-parameter detection on the metal working fluid, and can comprehensively reflect the state of the metal working fluid. Through the embodiment, after the components of the sample are separated, detection and analysis are carried out, the interference of pollutants on the detection result can be greatly reduced, the service life of the sensor is prolonged, the relevant parameters of the sample are calculated through the data difference, and the influence of the test environment or other factors on the detection result can also be reduced.
Thus, while the present invention has been described with reference to specific examples, which are intended to be illustrative only and not to be limiting of the invention, it will be apparent to those of ordinary skill in the art that changes, additions or deletions may be made to the disclosed embodiments without departing from the spirit and scope of the invention.
