Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high and low temperature cycle equipment, in particular to a corrosion-resistant and explosion-proof high and low temperature cycle device. BACKGROUND

[0002] The high and low temperature cycle box is also known as a high and low temperature alternating test box, which is a necessary test equipment in the fields of aviation, automobile, household appliances, scientific research, etc., and is used for testing and determining the parameters and performance of electrical, electronic and other products and materials after temperature environment changes of high temperature, low temperature or constant test. At present, for some test scenes with potential explosion risk or contact with corrosive substances, ordinary high and low temperature test boxes are difficult to meet the safety and durability requirements, and corrosion-resistant and explosion-proof high and low temperature cycle boxes are usually used for high and low temperature cycle test of the articles.

[0003] In the related art, the traditional corrosion-resistant and explosion-proof high and low temperature cycle box usually only has one test chamber, and the heating component and the refrigeration component are arranged in the test chamber at the same time. During the high and low temperature cycle test of the articles in the test chamber, when the high temperature test of the articles is completed by first heating the test chamber, the time required for decreasing from high temperature to low temperature increases, and the energy consumption also increases. Conversely, when the low temperature test of the articles is completed by first cooling the test chamber, the time required for increasing from low temperature to high temperature also increases, and the energy consumption also increases, and the energy saving effect is poor. Some corrosion-resistant and explosion-proof high and low temperature cycle devices have two chambers of high temperature test chamber and low temperature test chamber. If the high and low temperature environment switching test of the articles is required, the articles usually need to be manually transferred from the high temperature test chamber to the low temperature test chamber or from the low temperature test chamber to the high temperature test chamber. This operation mode is not only low in efficiency, time-consuming and laborious, but also the articles are easily disturbed by external environmental factors during the transfer process, which greatly reduces the accuracy of the test results.

[0034] Through the above structure, the working principle of the corrosion-resistant and explosion-proof high-low temperature circulating device provided by the application is as follows:

[0035] Before opening the seal door 4 of the high-temperature test cavity 2 front side, the article is placed in the placing groove on the placing seat 21, and then the seal door 4 is closed. When the high-temperature test is performed on the article, first, the electric push rod one 6 is controlled to retract and reset, so that the output shaft of the electric push rod one 6 drives the vertical plate one 7, the bearing plate 8 and the vertical plate two 9 to move horizontally and leftward in a straight line. The article on the placing seat 21 moves leftward. When the vertical plate one 7 is in contact with the limiting block 20 in the high-temperature test cavity 2, the operation of the electric push rod one 6 is stopped. At this time, the vertical plate two 9 is located in the passage opening 5. Then, the two electric push rod twos 11 are controlled to extend and operate, and the two electric push rod threes 14 are controlled to extend and operate. The output shaft end of the two electric push rod twos 11 pushes the corresponding horizontal baffle 12 to move close to each other until the top surface and the bottom surface of the vertical plate two 9 are in contact. The output shaft end of the two electric push rod threes 14 pushes the corresponding vertical baffle 15 to move close to each other until the front surface and the rear surface of the vertical plate two 9 are in contact. At this time, the gap between the vertical plate two 9 and the passage opening 5 is fully and effectively sealed. Then, the multiple electric heating pipes 16 are opened to operate to heat the high-temperature test cavity 2. The object is in a high-temperature state, and the test can be performed on the object. During the test process, the temperature of the high-temperature space can be monitored in real time by using the temperature sensor 18 in the high-temperature test cavity 2.

[0036] When the low-temperature test is performed on the article, the electric push rod two 11 and the two electric push rod threes 14 are retracted and reset, so that the two horizontal baffles 12 move away from each other, and the two vertical baffles 15 move away from each other, thereby releasing the seal of the gap between the vertical plate two 9 and the passage opening 5. Then, the electric push rod one 6 is controlled to extend and operate, so that the output shaft of the electric push rod one 6 drives the vertical plate one 7, the bearing plate 8 and the vertical plate two 9 to move horizontally and rightward in a straight line. The article on the placing seat 21 moves rightward and enters the low-temperature test cavity 3. When the vertical plate two 9 is in contact with the limiting block 20 in the low-temperature test cavity 3, the operation of the electric push rod one 6 is stopped. At this time, the vertical plate one 7 is located in the passage opening 5. Then, the two electric push rod twos 11 are controlled to extend and operate, and the two electric push rod threes 14 are controlled to extend and operate, so that the two horizontal baffles 12 move close to each other until the top surface and the bottom surface of the vertical plate one 7 are in contact, and the two vertical baffles 15 move close to each other until the front surface and the rear surface of the vertical plate one 7 are in contact. At this time, the gap between the vertical plate one 7 and the passage opening 5 is fully and effectively sealed. Then, the refrigerator 17 is opened to operate to cool and refrigerate the low-temperature test cavity 3. The object is in a low-temperature state, and the test can be performed on the object. During the test process, the temperature of the low-temperature space can be monitored in real time by using the temperature sensor 18 in the low-temperature test cavity 3.

[0037] Further, by controlling the extension or contraction of the electric push rod 6, the article can be conveniently transferred between the high-temperature test chamber 2 and the low-temperature test chamber 3, so as to facilitate the test of the article in the high-temperature environment and the low-temperature environment respectively, reduce the labor intensity, avoid the interference of the article by the external environment, and by using the sealing assembly, when the vertical plate two 9 is located in the passage opening 5, the gap between the vertical plate two 9 and the passage opening 5 can be fully sealed from the top, the bottom, the front side and the rear side respectively, when the vertical plate one 7 is located in the passage opening 5, the gap between the vertical plate one 7 and the passage opening 5 can be fully sealed from the top, the bottom, the front side and the rear side respectively, after the transfer of the object between the high-temperature test chamber 2 and the low-temperature test chamber 3 is completed, the temperature crosstalk of the high-temperature test chamber 2 and the low-temperature test chamber 3 can be effectively prevented, the accuracy of the test environment is ensured, the energy-saving effect is achieved, and the convenient high-low temperature cycle test operation is realized.
