Description

Technical Field

[0001] The utility model relates to an on-line dynamic titration system for pre-treatment of plating parts, belonging to the technical field of sample detection. Background Technique

[0002] Traditional detection of the plating pre-treatment bath solution usually adopts the single-point sampling method. This method cannot comprehensively reflect the state of the entire bath solution, and is prone to one-sidedness of the detection results. In addition, single-point sampling cannot monitor the composition changes at different positions in the bath solution, which is not conducive to timely discovery and handling of local abnormal conditions. The detection of the pre-treatment bath solution mainly relies on manual sampling and laboratory titration. This method has low efficiency, long time consumption, and is easily affected by human errors. Traditional detection means cannot achieve real-time monitoring. Galvanizing enterprises rely entirely on experience for production, resulting in inaccurate control of production, which in turn leads to an increase in the scrap rate of steel pipes, bringing huge economic losses and waste of energy and resources to the enterprises.

[0003] For the newly developed plating pre-treatment equipment, titration is required after sample injection. Therefore, a dynamic titration system needs to be developed accordingly. Content of the Utility Model

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] The present utility model is an on-line dynamic titration system for pre-treatment of plating parts, which is used for titration treatment of the bath solution for pre-treatment of plating parts.

[0027] The system includes a sampling unit, a liquid adding unit, a titration unit, a detection unit, a conversion unit, a data processing unit and a cleaning unit.

[0028] Among them, the sampling unit is used to quantitatively add samples to the detection unit, and the sampling unit can add the samples collected by the sampler to the detection unit.

[0029] The liquid adding unit is used to add reagents required for experiments to the detection unit. The liquid adding unit takes out the reagents required for experiments from the reagent bottles and then adds them to the detection unit.

[0030] The titration unit is used to add titrants to the detection unit. The titration unit takes out the titrants from the titrant containers and then titrates and adds them to the detection unit.

[0031] The conversion unit is responsible for collecting the sensor values in the detection unit and transmitting them to the data processing unit. The sensor is used to collect data.

[0032] The data processing unit controls the titration unit to perform titration and judge the titration end point according to the values of the sensors through a dynamic titration algorithm. The conversion unit and the data processing unit are communicatively connected to the central processor of the system.

[0033] The system is also provided with a cleaning unit, through which the pipelines and the detection unit in the entire titration system can be cleaned after the titration is completed.

[0034] The detection unit mainly includes a detector and a magnetic stirrer used in cooperation.

[0035] As Figure 1 、 Figure 2 shown, the structures of the sampling unit, the liquid adding unit and the titration unit of the titration system are the same. Specifically, as follows, they all include an installed injection pump 2 and a multi-way valve 3 that can be docked with the liquid outlet of the injection pump 2. The injection pump is installed on the injection pump bracket 1. The multi-way valve 3 is connected to each reagent bottle through pipelines and is also connected to the detector 4 through pipelines. Figure 1 There are a total of three groups of injection pumps, which respectively represent the sampling unit, the liquid adding unit and the titration unit.

[0036] Specifically, the multi-way valve 3 of the sample loading unit is connected to the sampler through a pipeline. The multi-way valve 3 of the liquid adding unit is connected to the reagent container through a pipeline. The multi-way valve 3 of the titration unit is connected to the titrant container through a pipeline. Taking the titration unit as an example, during operation, the injection pump 2 corresponding to the titration unit first sucks the titrant into the pump body. During this process, the multi-way valve 3 is connected to the titrant container. After the titrant is sucked into the injection pump 2, the multi-way valve 3 changes the passage state, and the multi-way valve 3 is connected to the detector 4. The injection pump 2 injects the titrant into the detector through the multi-way valve 3 and the pipeline.

[0037] The control system controls each unit to work in sequence. First, the sample loading unit injects the sample into the detector 4, then the liquid adding unit adds the reagent into the detector 4, and then the titration unit injects the titrant into the detector. During this process, the magnetic stirrer of the detection unit stirs the solution.

[0038] The cleaning unit of the system is used to clean the pipeline and the detector. Specifically, it usually includes a clean water container, a cleaning pump, and a cleaning valve 5. The clean water container is connected to the cleaning pump, and the cleaning pump is used to provide clean water for cleaning. The cleaning pump is also connected to the detector through the cleaning valve and the pipeline, and the cleaning pump inputs the clean water under high pressure into the pipeline and the detector for cleaning.

[0039] The utility model is applied to a hot-dip galvanizing production line. The dynamic titration system of this line can perform titration operations according to the instructions of the automatic control unit, and the real-time monitoring device monitors the potential value or other relevant parameters during the titration process, and transmits the data to the data processing unit for analysis and processing.

[0040] The utility model can perform titration operations in real time, quickly respond to changes in the bath solution composition, and timely adjust production parameters, thereby ensuring the quality stability of the pre-treatment of the plated parts.
