Description

Technical Field

[0001] This utility model relates to the field of waterproof coating technology, and in particular to an automatic device for determining the ammonia content in water-based coatings. Background Technology

[0002] Water-based coatings, as an environmentally friendly type of coating, are widely used in construction, furniture, automobiles, and many other fields due to their advantages such as low volatile organic compound (VOC) emissions, non-toxicity, odorlessness, and ease of application. However, ammonia is a common additive introduced into water-based coatings during their production and use. Ammonia primarily functions in water-based coatings to regulate pH and prevent microbial growth, but excessive ammonia can not only harm human health, such as irritating the respiratory tract, eyes, and skin, but also have adverse environmental effects, such as participating in atmospheric photochemical reactions to form secondary pollutants. Therefore, accurately determining the ammonia content in water-based coatings is of great significance for ensuring product quality, protecting human health, and maintaining environmental safety.

[0003] The existing testing procedure typically involves weighing the sample and placing it in a beaker, dissolving it in pure water, transferring it to a distillation flask, adjusting the pH to the specified range with sodium hydroxide solution and verifying the result, then adding anti-explosion beads and distilling. The distillate is collected in a beaker containing a standard sulfuric acid solution and an indicator. The condenser is adjusted when the distillate approaches the mark, and heating is stopped once the mark is reached. Finally, the distillate is transferred to an Erlenmeyer flask, the glassware is washed, and the washings are added to the flask for acid-base titration.

[0004] However, in actual titration operations, titration can only be performed manually, relying on the naked eye of personnel to judge the color change at the endpoint. This is inefficient, and different personnel are prone to deviations in their judgment of the color change at the endpoint, resulting in inaccurate test results. Utility Model Content

[0027] The following is combined Figures 1 to 3 The present invention will provide a detailed description of an automatic device for determining the ammonia content in water-based coatings through specific embodiments and application scenarios.

[0028] In the embodiments of this utility model, such as Figure 1 As shown, an automatic device 10 for determining the ammonia content in water-based coatings includes an operating table 100, a distillation module 200, a condensation module 300, a collection module 400, and an automatic titration module 500. The distillation module 200 is mounted on the operating table 100 and is used to distill the sample to be distilled. The condensation module 300 is connected to the distillation module 200 and communicates with the steam outlet of the distillation module 200. The condensation module 300 is used to condense the steam generated by the distillation module 200. The collection module 400 is located on the operating table 100 and corresponds to the liquid outlet of the condensation module 300. The collection module 400 is used to collect the sample to be titrated after condensation by the condensation module 300. The automatic titration module 500 is located on the operating table 100 and is used to automatically titrate the sample to be titrated collected by the collection module 400 and output the titration volume.

[0029] The operating platform 100 serves as the basic support structure for the entire device, providing a platform for the installation and fixation of other modules. It ensures the stability of the relative positions and connections between the modules, facilitating sample placement, equipment debugging, and routine maintenance by operators.

[0030] The distillation module 200 is responsible for heating and distilling the water-based coating sample to be distilled. By precisely controlling the heating temperature and distillation time, the distillation module 200 can release the ammonia component in the sample in the form of vapor, providing a basis for subsequent condensation and titration determination.

[0031] The condenser module 300 is connected to the steam outlet of the distillation module 200, and its function is to condense the steam generated by the distillation module 200. By circulating cooling water or other condensing media, the condenser module 300 cools the steam into a liquid, so that the ammonia component exists in the condensate in liquid form.

[0032] The collection module 400 is mounted on the operating table 100 and is positioned corresponding to the liquid outlet of the condensation module 300. The main function of the collection module 400 is to collect the sample to be titrated after condensation by the condensation module 300.

[0033] The automatic titration module 500 is responsible for automatically titrating the sample collected by the collection module 400. Through preset programs and algorithms, the automatic titration module 500 can precisely control the amount of titrant added and the titration speed, and automatically determine the titration endpoint based on real-time monitored reaction parameters (such as pH value, potential, etc.). The application of the automatic titration module 500 not only improves… The titration method offers improved efficiency and accuracy, eliminating subjective errors and human interference that can occur during manual titration. Furthermore, it automatically outputs key data such as titration volume, facilitating subsequent data processing and analysis.

[0034] This application achieves automated determination of ammonia content in water-based coatings by setting up a distillation module 200 to distill the sample to be distilled, a condensation module 300 to condense the steam generated by distillation, a collection module 400 to collect the condensed sample to be titrated, and an automatic titration module 500 to automatically titrate the collected sample and output the titration volume. This significantly improves the determination efficiency. At the same time, the application of the automatic titration module 500 eliminates the need for manual visual judgment of the titration endpoint, reducing human error and improving the accuracy of the test results.

[0035] Reference Figure 1 and Figure 2 According to the present invention, an automatic device 10 for determining the ammonia content in water-based coatings is provided. The device includes multiple distillation modules 200, which are arranged circumferentially along the outer periphery of the collection module 400.

[0036] Understandably, by setting up multiple distillation modules 200, the device can process multiple water-based coating samples simultaneously, achieving parallel distillation. This significantly improves detection efficiency and shortens the overall detection time.

[0037] Arranging multiple distillation modules 200 circumferentially along the outer periphery of the collection module 400 allows for full utilization of the space on the operating table 100, achieving a compact layout of the apparatus. This not only saves space but also makes the apparatus easier to operate and maintain.

[0038] Reference Figure 1 and Figure 2 According to the present invention, an automatic device 10 for determining the ammonia content in water-based coatings is provided. The collection module 400 includes a turntable 410 and multiple collection containers 420. The turntable 410 is rotatably connected to the operating table 100. The turntable 410 has multiple placement positions along its circumference. The collection containers 420 are placed on the turntable 410 through the placement positions.

[0039] Understandably, by setting up multiple collection containers 420, the device can simultaneously collect distillates from multiple distillation modules 200, with each collection container 420 corresponding to one distillation module 200, ensuring that the distillate of each sample can be collected independently and accurately.

[0040] The rotatability of the turntable 410 allows operators or the control system to easily position different collection containers 420 below the liquid outlet of the condensation module 300 to receive the corresponding distillate.

[0041] In some embodiments, the distillation module 200 is provided with a pressure sensor, which is used to detect the internal pressure of the distillation module 200 during distillation and control the start and stop of the distillation module 200 according to a preset pressure threshold.

[0042] Understandably, the pressure sensor can monitor the pressure changes inside the distillation module 200 in real time. With a preset pressure threshold, when the pressure inside the distillation module 200 exceeds the safe range, the pressure sensor will trigger the control mechanism to automatically stop the operation of the distillation module 200, thereby avoiding potential safety accidents.

[0043] Reference Figure 1 According to the present invention, an automatic device 10 for determining the ammonia content in water-based coatings also includes a photoelectric sensor 600. The photoelectric sensor 600 is located at the liquid outlet of the condensation module 300 and is positioned toward the collection container 420 of the collection module 400. The photoelectric sensor 600 is used to detect the liquid level in the collection container 420 to control the start and stop of the distillation module 200.

[0044] Understandably, the photoelectric sensor 600 can monitor the liquid level in the collection container 420 in real time, and sense changes in the liquid level by emitting and receiving light, providing accurate information for starting and stopping the distillation module 200.

[0045] When the liquid level in the collection container 420 reaches the preset height, the photoelectric sensor 600 will immediately send a signal to control the distillation module 200 to stop distillation, preventing liquid from overflowing or being collected in excess, and ensuring the accuracy and safety of the collection process.

[0046] Reference Figure 1 According to the present invention, an automatic device 10 for determining the ammonia content in water-based coatings is provided. The automatic titration module 500 includes a monitoring sensor assembly for monitoring reaction parameters during the titration process. The reaction parameters include at least one of pH value, potential, or conductivity.

[0047] Understandably, by monitoring reaction parameters (such as pH, potential, conductivity, etc.) in real time through sensor components, the endpoint is automatically determined based on preset endpoint conditions (such as jump point, fixed potential value), eliminating subjective errors in human judgment of color changes (such as indicator color change delay or visual deviation); repeatability error is usually <0.1%, far lower than the 1%~2% error of manual titration.

[0048] The automatic titration module 500 automates and automates the titration process by monitoring sensor components, reducing errors and uncertainties that may be caused by manual operation and improving the accuracy and reliability of the measurement results.

[0049] In some embodiments, the distillation module 200 further includes a cooling system for cooling the distillation module 200.

[0050] Understandably, a large amount of heat is generated inside the distillation module 200 during the distillation process. If the temperature is too high, it may cause equipment damage, sample decomposition, or safety accidents. The cooling system removes heat in a timely manner, ensuring that the distillation module 200 operates within a safe temperature range and preventing overheating.

[0051] Reference Figures 1 to 3 According to the present invention, an automatic device 10 for determining the ammonia content in water-based coatings further includes a three-axis moving clamping module 700. The three-axis moving clamping module 700 is disposed on the operating table 100 and is located between the collection module 400 and the self-titration module or at one end of the two in the parallel direction. The three-axis moving clamping module 700 is used to transfer the sample to be titrated from the collection module 400 to the automatic titration module 500.

[0052] Understandably, the three-axis moving gripping module 700 (typically referring to a robotic arm with gripping or suction functions, capable of moving in the X, Y, and Z directions) can automatically complete the sample transfer process from the collection module 400 to the automatic titration module 500. It can precisely position itself on the collection container 420 (located on the turntable 410 of the collection module 400) and the sample inlet of the automatic titration module 500, automatically gripping or suctioning the collected sample to be titrated and transporting it to the automatic titration module 500. This fully automates the entire process from sample distillation and collection to titration, requiring no manual intervention and greatly improving the overall operational efficiency.

[0053] Reference Figures 1 to 3 According to the present invention, an automatic device 10 for determining the ammonia content in water-based coatings includes a three-axis moving clamping module 700 comprising an X-axis moving component 710, a Y-axis moving component 720, a Z-axis moving component 730, and a clamping component 740. The X-axis moving component 710 is disposed on the operating table 100 along a first direction. The Y-axis moving component 720 is laterally connected to the X-axis moving component 710. The Z-axis moving component 730 is connected to the Y-axis moving component 720. The clamping component 740 is connected to the Z-axis moving component 730.

[0054] Understandably, the X-axis moving component 710 is positioned along the first direction (typically the length of the operating table 100) and is responsible for controlling the forward and backward movement of the gripping component 740 on the horizontal plane, achieving precise positioning of the sample in the first direction. The Y-axis moving component 720 is laterally connected to the X-axis moving component 710 and is responsible for controlling the left and right movement of the gripping component 740 on the horizontal plane. Working together with the X-axis moving component 710, it enables the sample to be positioned at any location on the horizontal plane. The Z-axis moving component 730 is connected to the Y-axis moving component 720 and is responsible for controlling the up and down movement of the gripping component 740 in the vertical direction, enabling precise gripping and placement of the sample at different heights.

[0055] Thus, through the combined movement in the three directions of X-axis, Y-axis and Z-axis, the three-axis moving gripping module 700 can realize the adjustment of the gripping component 740 in any position and posture in three-dimensional space, thereby adapting to sample containers of different shapes, sizes and positions.

[0056] The gripping component 740 is connected to the Z-axis moving component 730, which can precisely control the gripping force and position in the vertical direction, ensuring that the sample is not damaged during the gripping process and can be accurately placed into the automatic titration module 500.

[0057] In this embodiment, the automated operation of the three-axis moving gripping module 700 reduces manual intervention and improves the automation level and efficiency of the entire measurement process.

[0058] In some embodiments, an automatic device 10 for determining the ammonia content in water-based coatings further includes an intelligent heating system, which is embedded in the operating table 100 or set independently on the operating table 100, and is used to heat the distillation module 200.

[0059] Understandably, the intelligent heating system provides the distillation module 200 with an efficient, uniform, precise, and energy-saving heating method. It not only optimizes the distillation process itself, improving the efficiency and consistency of sample processing, but also directly enhances the accuracy of ammonia content determination results through precise temperature control. Simultaneously, its intelligent features also strengthen the equipment's safety and long-term operational reliability.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
