[01] The present invention relates to system testing based on characteristics of rock forming minerals used as a constructional material of a planetoid, whole-rock chemical composition of a basalt powder, particle size of the basalt powder and characteristics of rock forming minerals of cinnabar particles, and more particularly relates to a planetoid heating simulation device.
[02] At present, in the process of realizing simulated heating in terms of thermal metamorphism of the planetoid, when the influence of migration of mercury of the planetoid and fractionation of mercury isotopes is studied, the measured numerical values of temperature and pressure cannot reach corresponding temperature and pressure during the simulated heating experiment of the planetoid due to a thermal evolution “onion model” in the early stage of a chondrite parent body where outer matters lose heat with high efficiency and interior rocks are heated to a higher temperature but are cooled slowly, and partial residues exist during removal of mercury in the basalt powder. Therefore, the solution provides a planetoid heating simulation device to minimize the above defect.

[21] The technical solutions in embodiments of the present invention are clearly and completely described below in combination with the drawings in the embodiments of the present invention. Apparently, the embodiments described are merely some rather than all of the embodiments of the present invention. On the basis of the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts all fall within the scope of protection of the present invention.
[22] Embodiment:
[23] As shown in FIGs. 1-3, a planetoid heating simulation device, including a vacuum tank 1, where a removable cover 2 is rotatably connected to the upper end of the vacuum tank 1; a heating tube 3 is installed in the position of the center of a circle at the upper end of the removable cover 2; three 16-core aviation sealing plugs 5, an electronic pressure vacuum gauge 6 and three gas valves 7 are respectively installed at the upper end of the removable cover 2; the 16-core aviation sealing plugs 5, the electronic pressure vacuum gauge 6 and the gas valves 7 all are located on the outer side of the heating tube 3; flanges 8 are installed at the top and bottom of a powder bearing system; a tubular round hole plate 10 is fixedly connected between the top flange 8 and the bottom flange 8; a flange ring 9 is fixedly connected to the upper part of the powder bearing system; a metal strip 11 is fixedly connected to the lower end of the flange ring 9; a stainless steel filter screen 12 is fixedly connected to the outer end of the metal strip 11; and the vacuum pumps 4 are communicated through the gas valves 7.
[24] In the using process of the solution, thermal evaluation of the planetoid is simulated by way of core heating. The device mainly consists of four parts: a vacuum system, heating-temperature controlling system, a sample bearing system and a temperature measuring system. To acquire the temperature and pressure capable of being attained by the device when the simulated heating experiment of the planetoid is conducted and reasonably remove mercury in the basalt powder, in the embodiment, a pre-heating experiment is conducted on the basalt powder which simulates the constructional material of the planetoid under a vacuumized condition of -88 kpa and a barometric condition of 101 kpa.
[25] Further, the vacuum tank 1 is made from an acrylic transparent organic glass material, the vacuum tank 1 is arranged in a tubular shape, the tank wall is 2 cm thick, the outer diameter is 60 cm, the inner diameter is 56 cm, and the height is 60 cm.
[26] Further, a sealing strip is adhered to the lower end of the removable cover 2, and the sealing strip contacts the upper end of the vacuum tank 1.
[27] Further, a heat insulating layer 13 is arranged at the bottom end of the vacuum tank 1, and the heat insulating layer 13 is made from a high-temperature-resistant material.
[28] The vacuum system of the planetoid heating simulation device in the solution includes the vacuum tank 1 and the vacuum pumps 4. Moreover, the customized vacuum tank 1 is made from the acrylic transparent organic glass material. The vacuum tank is in a tubular shape, the tank wall is 2 cm thick, the outer diameter is 60 cm, the inner diameter is 56 cm, and the height is 60 cm. The removable cover 2 is 5 arranged at the top of the vacuum tank and is sealed by adhering the sealing strip. The tank cover is equipped with three 16-core aviation sealing plugs 5 for cross-tank chaining of thermal sensors in a vacuum state. Three gas valves 7 are reserved for connecting the vacuum pumps so as to achieve vacuumizing or vacuum pressure relief.
In addition, the removable cover 2 is equipped with the electronic pressure vacuum gauge 6 for monitoring the changing situation of the pressure in the tank. Meanwhile, to prevent deformation of the bottom of the tank due to overtemperature of the interior bearing system, the heat insulating layer 13 made from the high-temperature-resistant material is paved at the bottom of the tank. The extreme absolute pressure capable of being attained by the vacuum system in the embodiment is about 1.3 kpa, the relative pressure is -88 kpa, and the vacuum degree is close to 1/10 of barometric pressure.
[29] Further, the metal strip 11 is arranged in a cylindrical mesh shape.
[30] Further, the inner diameter of the flange 8 is set as 35.5 cm and the outer diameter thereof is set as 56.5 cm, while the inner diameter of the flange ring 9 is set as 25.5 cm and the outer diameter thereof is set as 43.5 cm.
[31] In the using process of the solution, the sample bearing system includes the flanges 8, the flange ring 9, the cylindrical round hole plate 10, the stainless steel filter screen 12 and the metal strip 11. Because a powder sample is hardly kept spherical and heated at the center, in the embodiment, the powder sample is kept cylindrical for heating. The 800-mesh stainless steel filter screen 12 1s used for wrapping the powder sample. Moreover, to keep the filter screen loading the powder sample cylindrical, the stainless steel filter screen 12 is welded to the metal strip 11 in the cylindrical mesh shape. The stainless steel filter screen 12 can keep effective exchange of gas in interior and exterior space of the sample while wrapping the powder sample. The mesh-shaped metal strip 11 1s welded to the flange ring 9 with the inner diameter of 25.5 cm and the outer diameter of 43.5 cm at the top to further form a whole. In addition, in the solution, by customizing the cylindrical round hole plate 10, the top and the bottom of the cylindrical round hole plate are respectively welded to the flange 8 with the inner diameter of 35.5 cm and the outer diameter of 56.5 cm. The powder sample is suspended as the flanges are overlapped at the top. The stainless steel filter screen 12 loading the powder sample is placed in the cylindrical round hole plate 10, and round holes in the cylindrical round hole plate 10 can serve as channels for exchange of interior and exterior gases.
[32] The temperature measuring system: at present, industrially frequently used three temperature sensors include a thermistor, a resistance temperature detector and a thermocouple. The three temperature sensors have their own unique features. The thermistor has the most basic feature that the resistance of the thermistor changes obviously with change of temperature, and the thermistor is usually made from a ceramic or a polymer, can be used for temperature measurement in an extreme environment and can achieve temperature measurement with a high precision within a limited temperature range, usually -90-130°C; the resistance temperature detector is also known as a resistance thermometer, is made from a known material with resistance changing with temperature and is usually made from platinum, features high precision and stability, and is frequently used in environments with a temperature lower than or equal to 600°C; and the thermocouple is also known as a thermoelectric couple, a kind of passive sensors, can output electric signals by virtue of its own thermoelectric effect, is the widely applied temperature sensor, and includes S, B, K, E,
J, T and N type thermocouples. The thermocouples of different types have different applicable temperatures and thermal sensitivities. In consideration of temperature measuring requirement >300°C, economy and temperature sensitivity in the solution, temperature monitoring and control involved in the embodiment both are completed through the K type thermocouple. The K type thermocouple usually made from a nickel-chrome alloy or a nickel-aluminum alloy has a large temperature range: -200-1200°C, with the temperature sensitivity of 41uV/°C. In addition, to facilitate piercing of the K type thermocouple into the powder without deformation in the piercing process, a probe-like armored thermocouple with high mechanical strength is used in the solution. The armored thermocouple is 15 cm long with the diameter of 1.0 mm. Thermocouple signals are read by a RS20K-C RS485 temperature transmitter which can import a temperature signal into a computer and monitor and store the temperature.
[33] The heating-temperature controlling system: because a spherical heater is hard to control and 1s insufficient in heating power, to improve the heating efficiency, the single-end heating tube with the length of 20 cm and the tube diameter of 2.4 cm is customized in the embodiment. The highest temperature of the single-end heating tube can reach 900-1000°C and the heating power is 1800W and 1200W. The single-end heating tube can reach the peak temperature endured by a 6-type common chondrite completely. The heating tube 3 is equipped with the K type thermocouple which controls the temperature of the heating tube. Temperature control is completed through a customized electrical control box. The electrical control box mainly includes a PID temperature controller and a relay. If the temperature of the heating tube exceeds a predetermined temperature, the relay cuts off a main circuit to stop power supply to the heating tube 3, so as to stop temperature rise; if the temperature of the heating tube 3 is lower than the predetermined temperature, the relay closes the main circuit to supply power to the heating tube, so as to realize temperature rise.
[34] Although embodiments of the present invention have been shown and described, it will be apparent to those of ordinary skill in the art that various changes, modifications, substitutions and variations may be made thereto without departing from the principles and spirit of the present invention, the scope of the present invention is defined by the appended claims and their equivalents.
