Description

Technical Field

[0001] The present invention relates to the field of production testing, and more specifically, to a quality testing method and system for measuring viscous liquid in production. Background Art

[0002] In the production of viscous liquids, such as phosphate esters and glues, accurate measurement of their physical properties is crucial for controlling the production process and ensuring product quality. However, due to their high viscosity and insufficient fluidity, these liquids are prone to problems such as insufficient mixing or insufficient reaction during the production process. In order to ensure the quality of viscous liquids, they need to be sampled and tested multiple times during the production process.

[0003] Among the many items tested, density is an important indicator of the production quality of viscous liquids. By testing the density, we can monitor the quality changes in the production process and ensure that the products meet the established standards and specifications. Existing sampling usually uses the hot water bath + hydrometer method for manual measurement. The basic steps of this method are to first place the chemical liquid in a hot water bath to make it reach a stable measurement temperature, because temperature changes will affect the density and viscosity of the liquid. Then, use a hydrometer to measure the specific gravity of the liquid, that is, the ratio of the density of the liquid to the density of a reference substance. After the measured specific gravity meets the requirements, the operator manually pours out a certain amount of solution for subsequent use or analysis.

[0004] However, the existing sampling and detection of viscous liquids has the following disadvantages:

[0005] Firstly, after sampling and testing, the samples are usually contaminated and cannot be recycled to the production line, resulting in a certain degree of waste. In order to avoid waste as much as possible, sampling is usually less, and a small sample size will affect the accuracy of the test results, especially when the liquid has a certain viscosity, a larger sample size is required to ensure the accuracy of the results.

[0006] Secondly, the existing measurement process requires precise temperature control, accurate reading of hydrometer data, and pouring out the solution at the right time, which places high demands on the operator, and the instability of human labor will also affect the test results. Summary of the invention

[0007] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide a quality testing method and system for measuring viscous liquid in production, so as to improve the accuracy of the quality testing results.

[0008] An object of the present invention is to provide a quality testing method for measuring viscous liquid in production, comprising:

[0009] S1. The liquid to be tested is transported from an external production container to a detection container;

[0010] S2. Adjust the temperature of the liquid and stir it, and continuously obtain the change data of the temperature, weight and volume of the liquid in the detection container;

[0011] S3. When the temperature is stable at the set value, the volume of the liquid to be measured is adjusted to the set value to obtain the weight data;

[0012] S4. After the collection is completed, the liquid is discharged and recovered into the production container;

[0013] S5. Obtain the production quality of the liquid through the change data and weight data.

[0014] In the technical solution, the production container is a container for storing liquid on a production line, and illustratively, it can be a reactor. The detection container is a container for storing liquid to be detected, and the liquid to be detected can be a semi-finished product or a finished product.

[0015] In step S1, the liquid to be tested is directly sampled from the production container on the production line into the detection container. Combined with step S4, after the data is collected, the liquid to be tested is directly recovered to the production line, realizing fully automatic sampling and recovery, and achieving high-efficiency detection.

[0016] In step S2, the temperature can be adjusted by heating or cooling until the set value is reached. By means of stripes and stirring, the temperature and concentration of the viscous liquid are made more uniform, the accuracy of the measurement data is improved, and the detection result is more reliable.

[0017] In step S4, after collecting data for quality inspection, the data can be further recycled into the production container, which will not cause waste and save costs. In this way, a large number of samples can be taken for quality inspection. Compared with the inspection of small samples, this solution can further improve the accuracy of the inspection results, especially when the liquid to be inspected is a semi-finished product. When unqualified is found, production can be adjusted in time to avoid cost and time waste caused by unqualified finished products.

[0018] In step S5, obtaining the production quality of the liquid through the change data can be understood as:

[0019] If the weight of the liquid to be tested changes during the temperature change process, it means that the liquid to be tested may be unqualified. The reasons may be: the reaction has not been completed in the production container, and after being transferred to the test container, the reaction continues with the temperature change, generating gas, resulting in a decrease in the mass of the liquid to be tested; or the liquid to be tested produces a new reaction in the test container, resulting in a change in mass. The staff can take measures such as replacing the sample for testing or repairing the testing equipment to improve the accuracy of the test.

[0020] The production quality of the liquid obtained by the weight data can be understood as:

[0021] When the temperature is stable at the set value, the density of the liquid to be tested is calculated by the weight data and the set volume value, so as to judge whether the liquid to be tested meets the quality requirements. If the density is too high, the step solute corresponding to the liquid to be tested is too much, otherwise it is too little.

[0022] When the liquid to be tested is phosphate ester, by measuring the density of the finished phosphate ester, the quality changes in the production process can be monitored to ensure that the product meets the established standards and specifications. Phosphates of different compositions and purities have different density values. By measuring the density of the finished phosphate ester, it is possible to preliminarily determine whether the composition and purity of the product meet the requirements. This is crucial to ensure the quality and performance of the product.

[0023] That is, this solution provides a quality reference for the liquid to be tested through the quality testing process and test results, providing double protection and improving the accuracy of liquid quality testing. At the same time, it avoids sample waste by recycling the liquid to be tested to the production line.

[0024] Furthermore, step S1 is specifically as follows:

[0025] The liquid to be tested is delivered from the production container to the test container according to the preset injection volume.

[0026] Further, the volume setting value of step S3 is less than the injection amount of step S1;

[0027] In step S3, the volume of the liquid to be measured is adjusted to a set value, specifically:

[0028] Drain excess liquid from the test container to a preset volume.

[0029] Adjusting the volume of the liquid to be tested to the set value can be done by discharging part of the liquid until the set value is reached. After the liquid to be tested is injected in step S1, the volume may change with stirring, temperature changes and other interference factors. If the injection amount in step S1 is directly used for weight detection and density calculation, it may lead to inaccurate density calculation and misjudgment, resulting in a waste of time and material costs. Therefore, in this solution, the adjusted set value is used as the parameter value of the volume, and the density is calculated based on this value, thereby improving the accuracy of the density test.

[0030] Furthermore, in step S2, the stirring is to keep at least 50% of the liquid in the detection container in motion;

[0031] After step S4, the method further includes:

[0032] S41. Obtain the residual weight of the liquid remaining in the detection container after the detection, and obtain the maintenance period of the detection container according to the residual weight.

[0033] In the present technical solution, the stirring is to keep at least 50% of the liquid in the detection container in a moving state, so as to ensure that the viscous liquid is stirred evenly, so that the temperature is evenly adjusted, and the accuracy of the measurement result is improved.

[0034] Since the liquid to be tested is viscous, it is easy to leave residue in the test container. By obtaining the residual weight, it is determined whether the test equipment needs maintenance. By maintaining the test equipment, the error caused by the residue can be reduced, thereby improving the accuracy of the test results.

[0035] Further, in step S41, the residual weight of the liquid remaining in the detection container after the detection is obtained, specifically:

[0036] S411. Inject a preset weight of cleaning agent into the detection container;

[0037] S412. After stirring and rinsing, obtain the weight change of the cleaning agent;

[0038] S413. Obtain the residual weight of the liquid through the weight change.

[0039] In the present technical solution, if the residual weight in the cleaning agent is too much, it means that there are a lot of residual substances originally remaining in the detection container, and it is possible that one cleaning cannot completely clean it. In this case, multiple cleanings or regular maintenance are required to avoid the influence of the residues in the detection container on the test results.

[0040] Another object of the present invention is to provide a quality detection system for viscous liquids, comprising: a feed pipeline and a return pipeline respectively connected to an external reaction container, and further comprising:

[0041] A controller storing any of the above density detection methods for measuring viscous liquids in production, and used for controlling the operation of the density detection system;

[0042] Testing containers;

[0043] A stirring component, connected to the detection container, for stirring the detection container;

[0044] A temperature control component, arranged on the detection container, for detecting and adjusting the temperature in the detection container;

[0045] A weighing component, arranged on one side of the detection container, connected to the detection container, and used to detect the weight of the reaction container;

[0046] A feed inlet, arranged at the upper part of the detection container and movably connected to the feed pipeline;

[0047] A discharge port is arranged at the lower part of the detection container and is connected with the return pipeline;

[0048] The controller is connected with the feed pipeline, the return pipeline, the stirring component, the temperature control component, and the weighing component.

[0049] The detection container is used to hold the viscous liquid to be tested; the movable connection is an interval connection, which can avoid the influence of the feed pipeline and the return pipeline on the weighing result and improve the accuracy of the weighing result. The detection system of this scheme obtains the volume and weight of the liquid to be tested, calculates the density, and judges whether the liquid quality is qualified; at the same time, it can be determined whether the liquid reacts in the detection container by whether the weight data of the detection process changes, and judge whether the liquid quality is qualified; and due to the setting of the return pipeline, the tested liquid can be transported back to the production line, so that large-scale sampling will not be wasted, and large-scale sampling can provide the accuracy of the detection result.

[0050] Further, the detection container at least includes a heat-conducting side wall;

[0051] The temperature control assembly comprises: a heating device and a temperature measuring device;

[0052] The temperature measuring device is connected to the side wall of the detection container;

[0053] The detection end of the temperature measuring device extends into the detection container and is close to the bottom of the detection container;

[0054] The heating plate of the heating device is arranged around the side wall of the temperature measuring container;

[0055] The heating sheet is non-closed to form an avoidance opening;

[0056] The temperature measuring device is arranged on the avoidance opening;

[0057] The stirring component avoids the detection end by partially reducing its width.

[0058] The heating plate of the heating device is arranged around the side wall of the temperature measuring container, which can improve the uniformity of heating the liquid inside the detection container. The detection end of the temperature measuring device extends into the detection container and can directly contact the liquid to be measured to measure the temperature, thereby improving the accuracy of temperature measurement. It is arranged at the bottom of the detection container, so that even if the amount of liquid to be measured is small, it can measure the temperature, so it is not affected by the amount of liquid to be measured, and improves the applicability of the system.

[0059] Furthermore, the detection container includes a material drop zone, a temperature control zone, and a stirring zone arranged in the temperature control zone in sequence from top to bottom;

[0060] The stirring assembly includes: a stirring blade and a driving device, and the driving device drives the stirring blade to rotate. The driving device is connected to the detection device;

[0061] The stirring blade is centrally symmetrical, is arranged in the stirring zone, and has a height matching that of the stirring zone; and the width of the stirring blade gradually decreases from top to bottom.

[0062] In the present technical solution, the temperature control zone is the part that contacts the temperature control component. The blanking zone is arranged on the temperature control zone. Compared with the setting with only one temperature control zone, the detection container of the present solution provides more flow space for the liquid to be tested, ensuring that the liquid is fully stirred and mixed, so that the temperature is uniform and the detection result is accurate. The width of the stirring plate gradually decreases from top to bottom, thereby avoiding the detection end of the temperature measuring device, while the upper part still maintains a large width to ensure the uniformity of stirring; avoiding the detection end at the lower part can avoid the temperature rise due to the partial contact of the stirring plate with the detection end, which causes the heat transfer of the stirring plate to make the temperature in the liquid uneven, thereby affecting the detection result. In addition, it can also avoid the mutual interference between the component structures and affect the normal operation.

[0063] Furthermore, it also includes: a support frame, and a receiving platform arranged on the support frame; the weighing assembly is connected to the receiving platform; the weighing assembly includes: a weighing body and a supporting structure; the weighing body is arranged below the detection container; the weighing position of the weighing body is connected to the middle of the bottom of the detection container through the supporting structure;

[0064] The feed inlet is arranged on the top surface of the detection container; the feed pipeline comprises: a feed pipe provided with a first control valve, the feed pipe extending into the material drop area; the feed inlet is larger than the feed pipe, so that a gap is left between the feed pipe and the detection container, thereby forming a movable connection between the feed pipeline and the detection container; the controller is connected to the first control valve;

[0065] And / or, the discharge port is arranged on the bottom surface of the detection container; the discharge port is also provided with a discharge pipe with a second control valve; the receiving platform is provided with a return liquid pool, and the return liquid pool is directly opposite to the discharge port, so that when the discharge port is opened, the liquid is received by the return liquid chamber, thereby forming a movable connection between the discharge pipeline and the detection container; the return liquid pool is provided with a drainage port, and the drainage port is connected to the return pipeline.

[0066] In the present technical solution, the feed port is larger than the feed pipe, so that the end of the feed pipe does not contact the feed port; the liquid return pool is opposite to the discharge port, which can be understood as the lower end of the discharge pipe is opposite to the liquid return pool, and the two do not contact; through the above arrangement, the weight measurement of the detection container is not affected, thereby improving the accuracy of the weight data.

[0067] Furthermore, it also includes a flushing pipeline; the flushing pipeline includes an input section and a discharge section, one end of the input section is used to connect to an external cleaning agent, and the other end is connected to the feed pipe; one end of the discharge section is used to connect to an external drain outlet, and the other end is connected to the drain outlet.

[0068] In the present technical solution, the outlet of the input end is connected to the detection container for inputting a cleaning agent to clean the detection container, thereby ensuring the cleanliness of the interior, preventing impurities or residues from affecting the detection results, and improving the accuracy of the detection results.

[0069] Compared with the prior art, the present invention has the following beneficial effects:

[0070] (1) The present invention provides a quality reference for the liquid to be tested through the quality detection process and the detection results, which provides double protection and improves the accuracy of liquid quality detection. At the same time, by recycling the liquid to be tested to the production line, sample waste is avoided, thus saving costs.

[0071] (2) The testing method and system of the present invention improve the accuracy of detection by realizing large-scale sampling; the testing method and system of the present invention are very simple to operate for testing liquid weight and volume, and human errors are greatly reduced, thereby further improving the accuracy and reliability of the test results.

[0072] (3) The testing method of the present invention is connected to the production line and the sampling recovery is fully automatic, which greatly improves the detection efficiency, increases the measurement frequency, improves the quality, and greatly reduces the contamination of the liquid.

[0073] (4) The testing method of the present invention obtains density by detecting weight and volume data, has a high degree of automation, and is simple to operate. Compared with traditional quality testing methods, the method and system of the present invention lower the operating threshold. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] S1. The liquid to be tested is transported from an external production container to a detection container;

[0084] S2. Adjust the temperature of the liquid and stir it, and continuously obtain the change data of the temperature, weight and volume of the liquid in the detection container;
