Description

Technical Field

[0001] This invention belongs to the field of space exploration, and in particular relates to a device for preparing large-scale vapor condensation ice to simulate lunar soil. Background Technology

[0002] The current process for preparing simulated lunar soil using vapor-condensed ice involves drying simulated lunar soil in an oven, placing it in an aluminum box, pre-cooling it, and then using a humidifier or a simple water vapor generator in a cold environment to adsorb ultrapure water onto the surface of the simulated lunar soil in the form of water vapor, thus preparing simulated lunar soil with the corresponding moisture content. However, this method suffers from the problem of water vapor in the cold environment being adsorbed onto simulated lunar soil particles during water vapor generation, affecting the accuracy of the corresponding moisture content. It also cannot eliminate the interference of water vapor factors in the air, resulting in a certain deviation for studying real lunar soil.

[0003] Traditional simulated lunar soil products have poor moisture uniformity. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1.

[0018] 3. The auger and auger shaft are used for rotary mixing, which is suitable for large-scale production of simulated lunar soil;

[0019] 4. The material is stirred upward by the auger and auger shaft to form a particle flow field. Water vapor is introduced from multiple directions to form a water vapor flow field. When the particle flow and the steam flow field converge, water molecules and small droplets will condense and adsorb on the surface of the low-temperature particles, and then stick to the surface of the simulated lunar soil particles. When the amount of water molecules adsorbed on the particle surface increases, an ice film will form on its surface, making the simulated lunar soil raw material contain water.

[0020] 5. By pre-cooling and emptying the glove box, the air inside the glove box can be prevented from affecting the moisture content of the simulated lunar soil product. Attached Figure Description

A separator plate 21 is slidably disposed within the inlet 20. One sidewall of the coating tank 2 is connected to the overflow bottle 22. The coating tank 2 has multiple air inlet pipes, each containing a water vapor conveying assembly 23 for controlling the water vapor flow rate. The auger and auger shaft 26... The auger and auger shaft 26 are coaxially connected within the coated tank 2. When the auger and auger shaft 26 rotate, they drive the material upwards. A liquid nitrogen passage 27 is provided on the side wall of the coated tank 2. A bottom scraper 28 is provided at the lower end of the auger and auger shaft 26.

It is a device that can maintain a certain liquid level and quickly remove excess liquid.

[0036] In this embodiment, the drive assembly includes a first sprocket 11, a servo motor 12, a second sprocket 24, and a chain 25. The upper end of the auger and auger shaft 26 is connected to the second sprocket 24. The second sprocket 24 is connected to the first sprocket 11 via the chain 25.

[0037] In this embodiment, the air intake pipeline includes an air intake pipe 231 and a bottom water vapor intake pipe 290. Four sets of air intake pipes are evenly distributed around the side wall of the membrane tank 2. Each set of air intake pipes includes multiple air intake pipes 231 arranged at intervals along the vertical direction. Three bottom water vapor intake pipes 290 are evenly distributed around the lower end face of the membrane tank 2 to ensure that the surface and sides of the simulated lunar soil particles are uniformly contacted and adsorbed with water vapor to form a water vapor flow field.

[0038] In this embodiment, the water vapor conveying assembly 23 includes a temperature sensor 230, a polyimide heat insulation tube 232, a polyimide barrier screen 233, and a spiral heating belt 234.

[0041] In this embodiment, the collection component 5 includes a funnel 50, a lunar soil receiving device 51, and a glove box 52. The inlet end of the funnel 50 is located directly below the discharge port of the coated tank 2, and the outlet end of the funnel 50 is connected to the inlet end of the lunar soil receiving device 51.

[0042] In this embodiment, the refrigerant delivery system 9 includes a first liquid nitrogen pipeline 299, a second liquid nitrogen pipeline 300, a liquid nitrogen flow sensor 301, and a nitrogen pipeline 302. The outlet end of the refrigerant generation system 3 is connected to the inlet end of the nitrogen pipeline 302.

The liquid nitrogen flow sensor 301 is electrically connected to the carrier gas flow control and temperature and humidity detection system 6.

[0043] When preparing lunar soil, a certain mass of anorthosite and basalt with a particle size of less than 1 mm are weighed out and placed in separate containers for later use.

[0044] Then, the two types of soil were placed in a mixer in a ratio of 7:3 for anorthosite and basalt, and the mixer was used to continuously mix them for 1 to 2 hours, starting slowly and then increasing the speed.

[0045] The raw materials are then dried using a vacuum microwave drying system. Microwave vibration assists in penetrating heating of the raw materials, causing the internal moisture to evaporate rapidly at a lower temperature. The vacuum environment prevents external air moisture from affecting the moisture content of the raw materials and lowers the boiling point of water, thus increasing the evaporation rate.

[0046] Then, the feeding window 15 is opened and the dried simulated lunar soil is added into the coating tank 2 through the feed inlet 20. Before adding materials into the coating tank 2, liquid nitrogen from the refrigerant generation system 3 is transported to the glove box 52 through the refrigerant conveying system 9 to pre-cool the glove box 52. After being vaporized by the liquid nitrogen, it enters the water blocking box 14 to form a waterless environment at the feed inlet 20. A portion of the liquid nitrogen enters the coating tank 2 to pre-cool the coating tank 2 and purge the air.

[0047] Then, water vapor is generated through the water vapor generation system 4, which is an evaporation box. Water is filled in the evaporation box and airflow is introduced into the water for cold evaporation. The introduction of airflow can accelerate the evaporation rate. Multiple baffles are set in the evaporation box to increase the contact area with water. Then, the water vapor is introduced into the water vapor conveying system 8 by the air compressor equipped with the water vapor generation system 4 and finally enters the film-coated tank. At the same time, the servo motor 12 is operated under the premise of maintaining a low temperature environment of -180℃ in the film-coated tank. The servo motor 12 drives the auger and auger shaft 26 to rotate. The rotation of the auger and auger shaft 26 will drive the simulated lunar soil to move upward to form a particle flow field. With the water vapor entering from multiple directions, a water vapor flow field is formed, so that the raw materials are mixed and stirred in the water vapor and low temperature environment to achieve the purpose of vapor condensation ice preparation.

[0048] Pulling the bolt 292 allows for unloading, simulating lunar soil falling into the lunar soil receiving device 51.

[0049] The carrier gas flow control and temperature and humidity detection system 6 accurately monitors the parameters of the water vapor and liquid nitrogen pipelines, and performs macroscopic control of each pipeline based on the data feedback from the data acquisition system 7.

[0050] In the above description, the water vapor generation system 4, the data acquisition system 7, the sensors used, the splitter, and the programs that may be used are existing technologies and will not be elaborated here.

[0051] The embodiments of the present invention disclosed above are merely illustrative of the invention. These embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
