Description

Technical Field

[0001] The present invention relates to the technical field of biaxial turntable high and low temperature test chambers, and particularly to an anti-condensation device for a biaxial turntable high and low temperature test chamber. Background Technique

[0002] The biaxial turntable high and low temperature test chamber is composed of a biaxial turntable and a high and low temperature test chamber. The high and low temperature test chamber can simulate extreme temperature environments, usually from -70°C to +150°C, and can be customized with a wider range according to requirements. It is a key device for testing the performance of products or materials. The biaxial turntable is used to simulate the multi-directional dynamic changes of products in actual use. The outer ring adopts a "U"-shaped ring frame structure and rotates around the horizontal axis, and can rotate continuously; the inner ring adopts a "T"-shaped structure and rotates around the vertical axis of the outer frame axis, and can rotate continuously. In an environment with rapid changes in high and low temperatures, condensation often forms on the samples inside the chamber and the bottom rotating shaft due to large temperature differences and high humidity. This not only affects the accuracy of test data but may also cause damage to the test equipment and the samples under test.

[0028] The anti-condensation device of the double-axis turntable high and low temperature test chamber mainly consists of a double-axis turntable 3, a test chamber 6 and an anti-condensation device. The anti-condensation device is composed of a rotating shaft heating component consisting of a shaft sleeve 17 and an infrared heater 23, and a dry air purging pipeline component consisting of an air outlet pipe 7, a connecting pipe 10, a solenoid valve 27, an adsorption dryer 31, an air source filter 33, a single union 35 and a compressed air source 37. The connecting rotating shaft rod 16 on the test chamber 6 mainly has a heating component, that is, a structure composed of a shaft sleeve 17 and an infrared heater 23, which is mainly installed on the high and low temperature box body 39 and sleeved on the bottom connecting rotating shaft rod 16 to radiatively heat the connecting rotating shaft rod 16 to achieve the anti-condensation effect. The infrared heater 23 is processed from some materials such as tungsten wire, carbon fiber and quartz tube. It is a heating device that uses infrared radiation to transfer heat energy. It directly heats the surface of an object by emitting infrared rays and has the characteristics of high efficiency, energy saving and environmental protection. The infrared heater generates infrared radiation through electric energy or gas. After the infrared rays are absorbed by the object, they are converted into heat energy to realize heating. The wavelength range of the adopted infrared radiation is 3μm to 1000μm. Infrared radiation does not require a medium to transfer, has a fast heating speed and a short response time. The infrared radiation heater is installed below the rotating shaft. The intelligent control system automatically adjusts the heating power according to the temperature and humidity data in the box to ensure that the temperature of the rotating shaft and its surrounding area is appropriate to avoid condensation. The dry air purging pipeline is coordinated by each component of the air outlet pipe 7, the connecting pipe 10, the solenoid valve 27, the adsorption dryer 31, the air source filter 33, the single union 35 and the compressed air source 37. The flow rate and humidity of the dry air introduced into the high and low temperature box body 39 are adjustable, ensuring that there is no condensation in the high and low temperature box body 39.

[0029] The compressed air source 37 first enters the single unit 35, where preliminary moisture filtration and pressure regulation are carried out. The appropriate pressure can be adjusted according to the working conditions. Then the compressed air enters the air source filter 33 for further filtration, which can remove water, filter oil and impurities, making the air entering the adsorption dryer 31 cleaner. The filtered air enters the adsorption dryer 31 for drying treatment, and the on-off is controlled by the solenoid valve 27 after drying. The dry air enters the rotary joint from the inlet pipe 26, that is, inside the outer shell 12. Through the rotor 40 inside the rotary joint, the dry air is sent into the high and low temperature box 39 from the outlet pipe 7, replacing the wet air in the high and low temperature box 39 with dry air to achieve the purpose of preventing condensation. The rotary joint is composed of a SUS304 stainless steel outer shell 12, a rotor 40, bearings 14, a gasket 13 and a mounting head 25. It is a device used to transfer gases such as compressed air and inert gases between rotating parts. Through the relative rotation of the rotor 40, bearings 14 and the outer shell 12 of the gas path rotary joint, the gas is transmitted from the stationary part to the rotating part, ensuring that the dry air can be stably sent into the test chamber 6 when one end is fixed and the other end rotates, and ensuring that the gas does not leak during the rotation process. The adsorption dryer 31 is a device used to remove moisture from compressed air. It adsorbs the moisture in the air through adsorbents such as activated alumina and molecular sieves, thereby achieving the drying of compressed air. This ensures the stable operation of the compressed air system and the product quality. The adsorption dryer 31 adopts the principle of physical adsorption and uses the porous structure of the adsorbent to adsorb the moisture in the compressed air. Its working process is usually divided into two stages: 1 Adsorption stage: The wet compressed air passes through the adsorbent bed layer, and the moisture is adsorbed by the adsorbent, and the dry air is output. 2 Regeneration stage: After the adsorbent is saturated, the moisture is desorbed by heating or decompression and other methods to restore the adsorption capacity. The dried air is continuously sent into the test chamber 6 through the pipeline system to reduce the humidity level in the chamber and further inhibit the formation of condensation. The control system dynamically adjusts the working state of the dryer according to the humidity and temperature data in the test chamber 6 to ensure the anti-condensation effect. The adsorption dryer can significantly improve the test accuracy and equipment stability of the test chamber, ensuring the accuracy and reliability of the test results.

[0030] An observation door 38 is provided on the front side of the through groove 5, and a display lamp 24 is connected to the infrared heater 23. The observation door 38 can facilitate the viewing of the sleeve 17 and the infrared heater 23, and the display lamp 24 gives a prompt display when the temperature of the infrared heater 23 changes.

[0031] The wavelength range of the infrared radiation of the infrared heater 23 is 3 μm - 1000 μm. The infrared heater 23 generates infrared radiation through electric energy or gas. After the infrared rays are absorbed by an object, they are converted into heat energy, thus achieving heating. The adopted wavelength range of the infrared radiation is from 3 μm to 1000 μm. The infrared radiation does not require a medium for transmission, has a fast heating speed, and a short response time. The infrared radiation heater is installed below the rotating shaft, and the heating power is automatically adjusted by the intelligent control system according to the temperature and humidity data inside the box to ensure that the temperature of the rotating shaft and its surrounding area is moderate and avoid condensation.

[0033] In the present invention, the anti-condensation device for the high and low temperature test chamber of the double-axis turntable mainly consists of a double-axis rotating table 3, a test chamber 6 and an anti-condensation device.
