Abstract
Description
Technical Field
[0001] This utility model relates to a small asphalt reflux device with self-cooling, belonging to the field of experimental equipment. Background Technology
[0002] Currently, most commercially available asphalt content analyzers and their reflux devices are assembled from parts, resulting in low integration, inconvenient storage, and long-term occupation of a fume hood, which is a waste of space for laboratories with limited space.
[0003] The testing process requires tap water for cooling, which is wasteful of water resources and can delay the testing schedule in the event of a water outage. Using a water bath with a compressor for cooling is also very heavy and bulky, further reducing the operating space. Utility Model Content
[0004] This invention provides a small asphalt reflux device with self-cooling, which has a high degree of integration and effectively reduces the size of the device.
[0005] The technical solution adopted by this utility model is a small asphalt reflux device with self-cooling, including a glass extraction device. The glass extraction device has a condenser and a heating flask. The condenser is set above the heating flask and communicates with the heating flask.
[0006] The self-cooling small bituminous reflux device also includes a water cooling device, a pump body, and a heating plate; the cold water outlet of the water cooling device is connected to the condenser inlet of the glass extraction device through the pump body, and the cold water return of the water cooling device is connected to the condenser drain of the glass extraction device.
[0007] The heating plate is located below the heating flask of the glass extraction device, and the heating surface of the heating plate is in contact with the lower surface of the heating flask of the glass extraction device.
[0008] The optimized version of the above-mentioned self-cooling small bituminous reflux device is a Soxhlet extractor for glass extraction.
[0009] The optimized version of the above-mentioned self-cooling small bituminous reflux device has a diaphragm water pump body connected to a temperature-sensing control instrument, with the control output terminal of the control instrument electrically connected to the control input terminal of the pump body.
[0010] In the optimized version, the aforementioned self-cooling small bituminous reflux device uses a semiconductor cooling water-cooling module as the water-cooling device, and the control output terminal of the control instrument is electrically connected to the control input terminal of the water-cooling device.
[0011] The optimized version of the above-mentioned self-cooling small bituminous reflux device also includes a switching power supply. The power input terminal of the switching power supply is connected to a power input port, and the power output terminal of the switching power supply is electrically connected to the power input terminal of the water cooling device and the pump body.
[0012] The power input port is electrically connected to the power input terminal of the power input port.
[0013] The advantages of this application are as follows: The technical solution uses semiconductor refrigeration as the refrigeration unit, effectively reducing its size and weight. Furthermore, it eliminates the reliance on a long-term tap water source, using water circulation for cooling, eliminating the need for operation near a water source. Instruments and sensors are used to monitor and control the refrigeration unit, ensuring the water temperature remains at the set temperature. The system has high integration, is easy to store, does not occupy the space of a fume hood, and saves laboratory space. Attached Figure Description

[0015] Figure 2 This is a schematic diagram of the Soxhlet extractor of this application. Detailed Implementation
[0016] The technical features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0017] As shown in the figure, this utility model is a small asphalt reflux device with self-cooling, including a power input port 1, a switching power supply 2, a control instrument 3, a water cooling device 4, a pump body 5, a heating plate 6, and a glass extraction device 10.
[0018] In one embodiment of this application, the glass extraction device 10 may employ a glassy Soxhlet extractor. The glass extraction device 10 has a condenser and a heating flask, with the condenser positioned above and in communication with the heating flask.
[0019] In other embodiments of this application, the glass extraction device 10 may be a glass extraction device designed for easy operation and maintenance, used for the extraction and separation of specific samples. The device is seamlessly integrated with the overall system, improving experimental or production efficiency.
[0020] The glass Soxhlet extractor is the standard glass instrument for testing asphaltene, and its structure is as follows: Figure 2 As shown, the structural components of the Soxhlet extractor, from top to bottom, include a condenser, an extractor, and a ground glass conical flask. The condenser is fitted inside the thin tube at the top of the extractor, and a conical filter paper is placed inside the extractor. The lower outlet of the extractor is connected to the inside of the ground glass conical flask.
[0021] The invention employs a standard glass extractor and cooling circulation system, resulting in a high degree of overall system integration. Compared to compressor-based refrigeration systems, semiconductor refrigeration systems are only half the size or even smaller. The refrigeration and heating reflux equipment can be integrated into a 40cm x 40cm (0.16 square meter) area, and its lightweight design (less than 3 kg) makes it easy to carry and transport. In contrast, compressor-based refrigeration systems require at least 0.5 square meters of space and weigh over 30 kg. The main advantages of this invention are its small size, light weight, ease of movement, suitability for temporary experimental sites without water, and greater suitability for laboratories with limited space. It is easy to store, can be taken out for use, and can be stored back in the experimental setup afterward, freeing up space for other tests.
[0022] In this application, the specific connections between the water circuit, the heating device, and the glass extraction device 10 are as follows.
[0023] The cold water outlet of the water-cooling device 4 is connected to the condenser inlet of the glass extraction device 10 via the pump body 5, and the cold water return of the water-cooling device 4 is connected to the condenser drain of the glass extraction device 10. The heating plate 6 is located below the heating flask of the glass extraction device 10, and the heating surface of the heating plate 6 is in contact with the lower surface of the heating flask of the glass extraction device 10.
[0024] In one embodiment of this application, the heating plate 6 is designed with a uniform heating surface, which can quickly and stably increase the fluid temperature. The heating plate employs temperature control technology to prevent overheating.
[0025] In this application, the heating plate 6 can be selected from existing commonly used electric heating equipment, such as the BY1515 heating table of Bangyuan and the GJR-1515 heating table of Gongjiangren.
[0026] In one embodiment of this application, all other equipment except the glass extraction device 10 can be integrated into a single housing. The heating surface of the heating plate 6 is placed on the surface of the housing, the button panel of the control instrument 3 is placed on the surface of the housing, and the power input port 1 is placed outside the housing, thus completing the system integration.
[0027] In one embodiment of this application, the pump body 5 can be a corrosion-resistant and wear-resistant diaphragm pump to ensure stable operation when handling high-temperature or highly corrosive fluids. The pump body 5 can be controlled using variable frequency control technology to achieve precise regulation of flow rate and pressure.
[0028] In this application, the pump body 5 can be a relatively mature pump body such as the 385 type general-purpose water pump or the 545 type DC micro diaphragm pump. Its pure copper motor is corrosion resistant, and its engineering plastic pump head is corrosion resistant and wear resistant. It has a wide operating temperature range, and can work normally in the temperature range of -20 to 100℃.

[0030] In one embodiment of this application, the control instrument 3 can be an existing STC-1000 intelligent digital display temperature controller.
[0031] In this application, the control output terminal of the control instrument 3 is electrically connected to the control input terminal of the water cooling device 4. In one embodiment of this application, the water cooling device 4 can be a semiconductor cooling water cooling module, employing high-efficiency semiconductor cooling technology combined with an optimized water cooling circulation system to achieve rapid cooling and heat dissipation. The module has a compact design, facilitating integration and maintenance.
[0032] In one embodiment of this application, the water-cooling device 4 can employ an LBS-12706 type electronic semiconductor thermoelectric cooler. To enhance the heat dissipation of the water-cooling device 4, four 40mm fans can be added to the aluminum heat sink fins of the electronic semiconductor thermoelectric cooler. The cooling surface of the electronic semiconductor thermoelectric cooler, combined with a 41*160mm water block and a diaphragm water pump, cools the circulating water. The LBS-12706 type electronic semiconductor thermoelectric cooler used in this embodiment is small in size and has stable power.
[0033] The power input terminal of the switching power supply 2 is connected to power input port 1, and the power output terminal of the switching power supply 2 is electrically connected to the power input terminals of the water cooling device 4 and the pump body 5.
