Description

Technical Field

[0001] This utility model relates to the field of extraction technology of soluble content in asphalt waterproof membrane, and in particular to an extraction device for testing the soluble content. Background Technology

[0002] In current testing methods for the soluble content of asphalt roofing membranes, the asphalt-based coating material (soluble matter) in the sample is dissolved in a solvent, leaving the base material as the remaining insoluble matter. The soluble content is calculated by weighing the difference in mass before and after dissolution, reflecting the content of effective asphalt components in the membrane.

[0003] When determining the soluble content during extraction, the point at which the extractant becomes lighter in color is used as the endpoint. However, if the personnel do not control the endpoint properly, it may lead to continuous reflux, resulting in low efficiency and energy waste. Utility Model Content

[0006] An extraction chamber, wherein the extraction chamber is provided with an extraction cavity;

[0007] A pure boiling liquid tank is provided, wherein a pure liquid chamber is provided inside the pure boiling liquid tank, and the pure liquid chamber is connected to the extraction chamber through a first pipe. The pure boiling liquid tank is used to collect the pure extract after distillation and to transport the collected pure extract to the extraction chamber.

[0008] A temperature-controlled liquid storage tank is provided with a liquid storage chamber inside. The liquid storage chamber is connected to the pure liquid chamber through a third pipe and is connected to the extraction chamber through a second pipe. The temperature-controlled liquid storage tank is used to provide distilled pure extract to the pure liquid chamber through the third pipe and to collect the extract overflowing from the extraction chamber through the second pipe.

[0010] According to the present invention, an extraction device for testing soluble content is provided, wherein the weighing module includes a pressure sensor and an analog-to-digital converter. The pressure sensor and the analog-to-digital converter are communicatively connected. The pressure sensor is used to collect the weight change of the extraction chamber in real time to generate an analog signal and transmit the analog signal to the analog-to-digital converter. The analog-to-digital converter is used to convert the analog signal into a digital signal and generate multiple digital signals to form a weight spectrum.

[0011] According to the present invention, an extraction device for testing soluble content is provided, the extraction device for testing soluble content further includes a condenser, which is located at the top of the third pipe, and is used to condense the gas after distillation in the storage chamber and then flow it to the pure liquid chamber.

[0012] According to the extraction device for testing soluble content provided by this utility model, the top of the third pipe is provided with an exhaust port.

[0013] According to the extraction device for testing soluble content provided by this utility model, there are multiple third pipes, which are connected side by side between the pure boiling liquid tank and the temperature-controlled storage tank.

[0014] According to the present invention, an extraction device for testing soluble content is provided, wherein the extraction chamber is provided with multiple limiting grooves, and the limiting grooves are used to place the sample to be tested.

[0015] According to the present invention, an extraction device for testing soluble content is provided, wherein the extraction chamber is provided with a drying module and a ventilation module, the ventilation module is connected to the extraction chamber, and the drying module is used to heat and dry the extraction chamber.

[0017] According to the extraction device for testing soluble content provided by this utility model, a first one-way flow valve is provided on the first pipeline. The first one-way flow valve is used to control the liquid in the pure liquid chamber to flow into the extraction chamber after reaching a preset threshold.

[0018] Alternatively, a one-way valve may be provided on the second pipeline, which is used to control the unidirectional flow of liquid from the extraction chamber to the storage chamber.

[0019] According to the present invention, an extraction device for testing soluble content is provided, the extraction device for testing soluble content further includes a controller, the controller being communicatively connected to the temperature-controlled storage tank, and the controller controlling the temperature of the temperature-controlled storage tank according to a preset command.

[0020] The extraction device for testing soluble content provided by this invention can accurately record weight changes during the extraction process by real-time monitoring of the extraction tank weight through a weighing module. As the asphalt-based coating material is extracted from the sample and dissolved in the extractant, the weight of the extraction tank changes. This change can be visually displayed through a weight graph. When the weight change stabilizes, it indicates that the extraction process is nearing completion, allowing for accurate determination of the extraction endpoint. This method is more accurate and reliable than traditional methods relying on visual judgment of extractant color changes, thus facilitating convenient determination of the extraction endpoint. Furthermore, through a closed-loop system, the extractant is recovered and reused during the extraction process, reducing the consumption of fresh extractant. This not only reduces the purchase cost of the extractant but also reduces waste liquid treatment expenses. In addition, accurate determination of the extraction endpoint avoids over-extraction and solvent waste, further reducing costs. Simultaneously, the recycling of the extractant reduces the waiting time for extractant distillation and cooling, making the entire extraction process more continuous and efficient. Moreover, automated extraction endpoint determination reduces human intervention and unnecessary waiting time, thereby improving extraction efficiency. Attached Figure Description

[0033] The following is combined with Figures 1 to 3 The extraction device for testing soluble content provided in this utility model will be described in detail through specific embodiments and application scenarios.

[0034] In the embodiments of this utility model, such as Figure 1 As shown, the extraction device 10 for testing soluble content includes an extraction chamber 100, a pure boiling liquid tank 200, a temperature-controlled storage tank 300, and a weighing module. The extraction chamber 100 contains an extraction chamber 110; the pure boiling liquid tank 200 contains a pure liquid chamber, which is connected to the extraction chamber 110 via a first pipe 400. The pure boiling liquid tank 200 is used to collect the distilled pure extract and transport the collected pure extract to the extraction chamber 110; the temperature-controlled storage tank 300 contains a storage chamber, which is connected to the extraction chamber 110 via a third pipe 600. Pure liquid chamber The liquid storage chamber is connected to the second pipe 500. extraction Cavity 110 The interconnected, temperature-controlled storage tank 300 is used to supply the distilled pure extract to the pure liquid chamber through the third pipe 600, and to collect the extract overflowing from the extraction chamber 110 through the second pipe 500; the weighing module is located below the extraction tank 100, and the weighing module is used to monitor the weight change of the extraction tank 100 in real time to form a weight map.

[0035] The extraction chamber 100 is equipped with an extraction cavity 110 for placing the asphalt roll sample to be tested. The extraction chamber 100 is the main place for the extraction operation. The extraction cavity 110 provides a closed space for the sample, allowing the asphalt-based coating material to be effectively extracted under the action of the solvent.

[0036] The pure boiling liquid tank 200 has a pure liquid chamber, which is connected to the extraction chamber 110 via a first pipe 400. This chamber is used to collect the pure extract after distillation and to transport the collected pure extract to the extraction chamber 110. The pure boiling liquid tank 200 is responsible for collecting and storing the pure extract after distillation. Through the connecting pipe, this pure extract can be transported back to the extraction chamber 110, realizing the recycling of the extractant.

[0037] The temperature-controlled storage tank 300 has a storage chamber, which is connected to the pure liquid chamber via a third pipe 600 and to the extraction chamber 110 via a second pipe 500. It is used to supply the distilled pure extract and collect the extract overflowing from the extraction chamber 110. The temperature-controlled storage tank 300 can regulate and maintain the solvent temperature, ensuring that the extraction process takes place at a suitable temperature. It supplies the distilled extract to the pure liquid chamber via the third pipe 600 and collects the extract overflowing during the extraction process via the second pipe 500, avoiding waste.

[0038] A weighing module is located below the extraction chamber 100 to monitor the weight changes of the extraction chamber 100 in real time, generating a weight graph. This real-time monitoring allows for precise tracking of the extraction process of the asphalt-based coating material. The weight graph provides the operator with a visual indication of the extraction progress; when the weight changes stabilize, it indicates that the extraction process is nearing completion, allowing for accurate determination of the extraction endpoint.

[0039] The extraction device 10 for testing soluble content also includes a temperature-controlled heater, which is located inside a temperature-controlled storage tank 300 and is used to heat the extract in the storage tank.

[0040] This application utilizes a weighing module to monitor the weight of the extraction chamber 100 in real time, accurately recording weight changes during the extraction process. As the asphalt-based coating material is extracted from the sample and dissolved in the extractant, the weight of the extraction chamber 100 changes, which can be visually displayed through a weight graph. When the weight change stabilizes, it indicates that the extraction process is nearing completion, allowing for accurate determination of the extraction endpoint. This method is more accurate and reliable than traditional methods relying on visual judgment of extractant color changes, thus facilitating convenient endpoint determination. Furthermore, through a closed-loop system, the extractant is recovered and reused during the extraction process, reducing the consumption of fresh extractant. This not only lowers the purchase cost of the extractant but also reduces waste liquid treatment expenses. In addition, accurate endpoint determination avoids over-extraction and solvent waste, further reducing costs. Simultaneously, the recycling of the extractant reduces the waiting time for extractant distillation and cooling, making the entire extraction process more continuous and efficient. Moreover, automated endpoint determination reduces human intervention and unnecessary waiting time, thereby improving extraction efficiency.

[0041] In one embodiment, the weighing module includes a pressure sensor and an analog-to-digital converter (ADC). The pressure sensor and the ADC are communicatively connected. The pressure sensor is used to collect the weight change of the extraction chamber 100 in real time to generate an analog signal and transmit the analog signal to the ADC. The ADC is used to convert the analog signal into a digital signal and generate multiple digital signals to form a weight spectrum.

[0042] Understandably, the pressure sensor is used to collect the weight changes of the extraction chamber 100 in real time and generate an analog signal. The analog-to-digital converter is connected to the pressure sensor to convert the analog signal into a digital signal. By generating multiple digital signals, a weight spectrum is formed. By analyzing the weight spectrum, it is possible to accurately determine whether the extraction process is complete. That is, when the weight change tends to stabilize, it indicates that the extraction has approached or reached its endpoint.

[0043] The weighing module in this embodiment achieves accurate monitoring and recording of weight changes in the extraction chamber 100 through the coordinated operation of a pressure sensor and an analog-to-digital converter. This provides the operator with a reliable method to determine the extraction endpoint, thereby improving the automation, efficiency, and accuracy of the entire extraction device.

[0044] Reference Figure 1 and Figure 2 According to the present invention, an extraction device 10 for testing soluble content is provided. The extraction device 10 for testing soluble content also includes a condenser 900. The condenser 900 is located at the top of the third pipe 600. The condenser 900 is used to condense the gas after distillation in the storage chamber and then flow it to the pure liquid chamber.

[0045] Understandably, the condenser 900 is located at the top of the third pipe 600. The condenser 900 is used to condense the gas produced after distillation in the storage chamber before it flows into the pure liquid chamber. The main function of the condenser 900 is to convert the gas (mainly solvent vapor) produced after distillation in the storage chamber into a liquid state through cooling; this process is called condensation. Through condensation, the solvent that evaporates during distillation can be recovered, reducing solvent loss and improving the solvent recycling rate.

[0046] Reference Figure 1 and Figure 2 According to the present invention, an extraction device 10 for testing soluble content is provided, wherein the top of the third pipe 600 is provided with an exhaust port 610.

[0047] Understandably, during the extraction process, the solvent in the storage chamber is heated and distilled, generating vapor. Most of this vapor is condensed into liquid solvent as it passes through condenser 900, but some non-condensable gases (such as non-solvent components in air and water vapor) may remain. The function of vent 610 is to release these non-condensable gases, preventing their accumulation in the system and affecting condensation efficiency and extraction results. Simultaneously, vent 610 also prevents impurities and contaminants in the system from re-entering the solvent circulation, maintaining solvent purity and thus ensuring the accuracy of the extraction results.

[0048] Reference Figure 1 According to the extraction device 10 for testing soluble content provided by this utility model, there are multiple third pipes 600, which are connected side by side between the pure boiling liquid tank 200 and the temperature-controlled storage tank.

[0049] Understandably, the design of multiple third pipes 600 connected in parallel in the extraction device 10 for soluble content testing plays a role in increasing flow rate, dispersing pressure, improving safety, optimizing heat exchange, increasing flexibility, and maintaining fluid flow uniformity, thereby improving the performance and efficiency of the entire extraction system.

[0050] Reference Figure 3 According to the present invention, an extraction device 10 for testing soluble content is provided, wherein the extraction chamber 110 is provided with a plurality of limiting grooves 120, which are used to place the sample to be tested.

[0051] Understandably, the limiting groove 120 provides a fixed position for the sample to be tested, ensuring that the sample does not move or float during the extraction process, thereby maintaining sample stability. At the same time, the design of the limiting groove 120 ensures that the sample is uniformly exposed to the solvent, and each sample can independently contact the solvent, which helps to achieve a uniform extraction effect and reduce cross-contamination between samples.

[0052] Multiple limiting slots 120 allow for the simultaneous placement of multiple samples, which improves the processing capacity of the extraction device, enabling the extraction of multiple samples at the same time and increasing the efficiency of the laboratory.

[0053] In some embodiments, the extraction chamber 100 is provided with a drying module and a ventilation module. The ventilation module is connected to the extraction chamber 110, and the drying module is used to heat and dry the extraction chamber 110.

[0054] Understandably, some extractant may remain in the sample after extraction. The drying module effectively evaporates and removes this residual solvent by heating the extraction chamber 110, ensuring the sample is completely dry. The ventilation module, directly connected to the extraction chamber 110, effectively removes harmful gases generated during the extraction process. The drying and ventilation modules not only ensure complete sample drying and testing accuracy but also protect the safety of laboratory personnel and optimize the efficiency and stability of the entire testing process.

[0055] In one specific embodiment, after the extraction process is completed and the extractant has flowed out, the extraction chamber 100 is ventilated for 30 minutes, then heated to 105 degrees Celsius and dried for 2 hours before the process ends.

[0056] Reference Figure 1 and Figure 2 According to the present invention, an extraction device 10 for testing soluble content is provided. The extraction device 10 for testing soluble content further includes a fourth pipe 700, which is connected between the pure liquid chamber and the storage chamber. The fourth pipe 700 is used to return the pure extract to the storage chamber when the pure liquid chamber reaches a preset threshold.

[0057] Understandably, the primary function of the fourth pipe 700 is to control the liquid level in the purified liquid chamber. When the liquid level in the purified liquid chamber reaches a preset threshold, the fourth pipe 700 can return excess purified extract to the storage chamber. This prevents liquid overflow from the purified liquid chamber and maintains stable system operation.

[0058] In one embodiment, a second one-way flow valve 710 is provided on the fourth pipe 700 to control the flow of extract from the pure liquid chamber to the storage chamber when there is too much extract.

[0059] Reference Figure 1 and Figure 2 According to the extraction device 10 for testing soluble content provided by this utility model, a first one-way flow valve 410 is provided on the first pipe 400. The first one-way flow valve 410 is used to control the liquid in the pure liquid chamber to flow into the extraction chamber 110 after reaching a preset threshold; or, a one-way valve 510 is provided on the second pipe 500. The one-way valve 510 is used to control the liquid in the extraction chamber 110 to flow unidirectionally into the storage chamber.

[0060] Understandably, the first one-way flow valve 410 ensures that the liquid flows only in one direction, from the pure liquid chamber to the extraction chamber 110. This prevents backflow and maintains the directionality of fluid flow. When the liquid level in the pure liquid chamber reaches a preset threshold, the first one-way flow valve 410 opens, allowing the liquid to flow into the extraction chamber 110. This helps control the extraction process, ensuring that liquid transfer only occurs when necessary.

[0061] The one-way valve 510 ensures that the liquid can only flow from the extraction chamber 110 to the storage chamber, and cannot flow in the opposite direction. This ensures the effectiveness of the extraction process and prevents the extracted liquid from being remixed.

[0062] Reference Figure 1 According to the present invention, an extraction device 10 for testing soluble content is provided. The extraction device 10 for testing soluble content also includes a controller 800. The controller 800 is communicatively connected to a temperature-controlled liquid storage tank 300. The controller 800 controls the temperature of the temperature-controlled liquid storage tank 300 according to a preset command.

[0063] Understandably, the controller 800 can monitor the temperature inside the temperature-controlled storage tank 300 in real time and adjust it based on the difference between the actual temperature and the set value. This ensures that the temperature inside the storage chamber remains within the optimal range throughout the extraction process. Furthermore, the controller 800 can automatically start, stop, or adjust the temperature of the temperature-controlled storage tank 300 according to preset instructions or programs. This reduces manual intervention and improves work efficiency.

[0064] In some embodiments, the controller 800 may further include a display module for displaying the generated weight map.

[0065] 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.
