[0033] As shown in Figures 1 to 5, a temperature control device for an ultra-low temperature impact test includes a housing 1 and a feeding hopper 11, a first auxiliary hopper 12, a reaction hopper 13, and a second auxiliary hopper 14 disposed inside the housing 1 and distributed along one end of the housing 1 to the other. A transfer member 2 is slidably connected to the bottom of the housing 1, and the transfer member 2 passes through the feeding hopper 11, the first auxiliary hopper 12, the reaction hopper 13, and the second auxiliary hopper 14. The device also includes a temperature member 3 connected to the first auxiliary hopper 12, the reaction hopper 13, and the second auxiliary hopper 14 respectively, and the temperature member 3 is used to adjust the temperature of the first auxiliary hopper 12, the reaction hopper 13, and the second auxiliary hopper 14.

[0034] In this embodiment, the transfer component 2 passes through the loading hopper 11, the first auxiliary hopper 12, the reaction hopper 13, and the second auxiliary hopper 14. The temperature control component 3 is connected to the first auxiliary hopper 12, the reaction hopper 13, and the second auxiliary hopper 14 to ensure that these hoppers reach the required temperature conditions when processing materials. Thus, the transfer component 2 is used to load the object to be tested from the loading hopper 11. Then, it moves to the reaction hopper 13. When cooling is required, the temperature control component 3 first controls the first auxiliary hopper 12 and the second auxiliary hopper 14 to cool to the required temperature for the object to be tested. Then, the temperature control component 3 controls the reaction hopper 13 to cool, while simultaneously connecting the first auxiliary hopper 12 and the second auxiliary hopper 14 to the reaction hopper 13 for more precise and rapid temperature control. This solves the problem of inaccurate test data caused by the inability to effectively control the cooling temperature in existing technologies that use liquid nitrogen spraying for cooling.

[0035] In some embodiments, the housing 1 is provided with a slide groove 15, which is respectively disposed on one side of the feeding hopper 11, the first auxiliary hopper 12 and the reaction hopper 13, and also includes a partition 4, which includes a partition door 41 that is slidably connected to the slide groove 15.

[0036] In some embodiments, the partition 4 further includes a partition switch 42, which includes a lifting screw block 43 connected to the partition door 41 and a lifting screw 44 threadedly connected to the lifting screw block 43. A screw gear 45 is connected to the lifting screw 44, and a motor gear 46 is meshed with the screw gear 45. A lifting motor 47 is connected to the motor gear 46, and the lifting motor 47 is used to drive the lifting screw 44 to rotate, so as to drive the partition door 41 to rise or fall.

[0037] In this embodiment, the slide groove 15 is provided on the housing 1, located on one side of the feeding bin 11, the first auxiliary bin 12, and the reaction bin 13, respectively. The slide groove 15 provides a sliding track for the partition door 41, allowing the feeding bin 11 and the first auxiliary bin 12 to remain relatively closed; the first auxiliary bin 12 and the reaction bin 13 to remain relatively closed; and the reaction bin 13 and the second auxiliary bin 14 to remain relatively closed. Simultaneously, when the partition door 41 is open, the transfer member 2 can move between these bins. The partition door 41 is slidably connected to the slide groove 15 and can slide up and down within the slide groove. The partition door 41 is used to open or close the passage between different bins to control the movement of the object to be tested. The lifting screw block 43 is connected to the partition door 41 and moves up and down with the partition door 41. The lifting screw block 43 has internal threads and cooperates with the lifting screw 44. The lifting motor 47 is connected to the motor gear 46, providing power to the entire partition switching component. When the lifting motor 47 rotates, it drives the motor gear 46 to rotate, the motor gear 46 drives the screw gear 45 to rotate, the screw gear 45 drives the lifting screw 44 to rotate, and the lifting screw 44 drives the lifting block 43 to move up and down.

[0038] In some embodiments, the transfer member 2 includes a slide rail 21 connected to the bottom of the housing 1. The slide rail 21 is located directly below the loading bin 11, the first auxiliary bin 12, the reaction bin 13, and the second auxiliary bin 14. A transfer frame 22 is slidably connected to the slide rail 21. The transfer frame 22 is used to load the test object from the loading bin 11 and transfer it to the reaction bin 13.

[0039] In this embodiment, the slide rail 21 is connected to the bottom of the housing 1, located directly below all the compartments. The slide rail 21 provides a sliding track for the transfer frame 22, ensuring a smooth and accurate transfer process. The transfer frame 22 is slidably connected to the slide rail 21 and can move freely along the slide rail. The main function of the transfer frame 22 is to load the test object from the loading bin 11 and then move it along the slide rail to the reaction chamber 13 for further processing.

[0040] In some embodiments, the transfer member 2 further includes a transfer screw 23 threadedly connected to the transfer frame 22. One end of the transfer screw 23 is connected to a transfer motor 24, which drives the transfer screw 23 to rotate, thereby moving the transfer frame 22.

[0041] In this embodiment, the transfer screw 23 has threads on its surface, which engage with the internal threads of the transfer frame 22. When the transfer screw 23 rotates, it drives the transfer frame 22 to move along the slide rail 21. The transfer motor 24 is connected to one end of the transfer screw 23, providing power to the transfer screw. When the transfer motor 24 rotates, it drives the transfer screw 23 to rotate, thereby realizing the movement of the transfer frame 22. The transfer process is as follows: the test object is placed on the transfer frame 22 from the loading bin 11; the transfer motor 24 is started, driving the transfer screw 23 to rotate; since the transfer frame 22 and the transfer screw 23 are threadedly connected, the rotation of the transfer screw will drive the transfer frame 22 to move along the slide rail 21 from the loading bin 11 to the reaction chamber 13.

[0042] In some embodiments, the temperature element 3 includes temperature chambers 31 disposed on both sides of each of the first auxiliary chamber 12, reaction chamber 13 and second auxiliary chamber 14.

[0043] In this embodiment, to better adjust the temperature of the first auxiliary chamber 12, reaction chamber 13, and second auxiliary chamber 14, temperature chambers 31 are independently set on both sides of each of the first auxiliary chamber 12, reaction chamber 13, and second auxiliary chamber 14. By lowering the temperature chambers 31 on both sides of each of the first auxiliary chamber 12, reaction chamber 13, and second auxiliary chamber 14 to the required temperature in advance, precise temperature control can be effectively ensured.

[0044] In some embodiments, each of the temperature chambers 31 is connected to a vent valve 32, which is used to connect the temperature chambers 31 on both sides of the first auxiliary chamber 12, the reaction chamber 13, and the second auxiliary chamber 14 with the first auxiliary chamber 12, the reaction chamber 13, and the second auxiliary chamber 14.

[0045] In this embodiment, temperature chambers 31 are disposed on both sides of each first auxiliary chamber 12, reaction chamber 13, and second auxiliary chamber 14 for temperature control of these chambers. Each temperature chamber 31 is connected to a vent valve 32. The main function of the vent valve 32 is to connect the temperature chamber 31 to the adjacent first auxiliary chamber 12, reaction chamber 13, and second auxiliary chamber 14. Through the vent valve 32, gas exchange between the temperature chamber 31 and adjacent chambers can be achieved. This helps to create a more uniform temperature distribution within the chamber, improving the accuracy and response speed of temperature control. When it is necessary to adjust the temperature or pressure within the chamber, the control system sends a command to the vent valve 32 to open or close it. Opening the vent valve 32 allows gas exchange between the temperature chamber 31 and adjacent chambers, thereby achieving temperature or pressure regulation. Closing the vent valve 32 prevents gas exchange, helping to maintain a stable temperature within the chamber.

[0046] In some embodiments, the tops of the first auxiliary chamber 12, the reaction chamber 13, and the second auxiliary chamber 14 are all connected to a connecting pipe 33. The connecting pipe 33 is used to connect the temperature chambers 31 on both sides of the first auxiliary chamber 12, the reaction chamber 13, and the second auxiliary chamber 14. Each connecting pipe 33 is connected to a main pipe 34, and the main pipe 34 is connected to a nitrogen cylinder 35. Each connecting pipe 33 and the main pipe 34 are connected to a switch valve 36, which is used to control the connection or closure of the main pipe 34 and the connecting pipe 33.

[0047] In this embodiment, a connecting pipe 33 is connected to the top of each first auxiliary chamber 12, reaction chamber 13, and second auxiliary chamber 14. The main function of the connecting pipe 33 is to connect the temperature chambers 31 on both sides of the same chamber to achieve a more uniform temperature distribution. A main pipe 34 is connected to multiple connecting pipes 33, forming a centralized gas delivery channel. The function of the main pipe 34 is to deliver inert gases such as nitrogen from the nitrogen cylinder 35 to each connecting pipe 33. A switch valve 36 is connected between each connecting pipe 33 and the main pipe 34 to control the connection or closure of the main pipe 34 and the connecting pipes 33. The opening and closing of the switch valve 36 is controlled by...

[0048] In some embodiments, each of the temperature chambers 31 is connected to a temperature sensor 37.

[0049] In this embodiment, a temperature sensor 37 is connected to each temperature chamber 31 to detect the temperature inside each temperature chamber 31. This further improves the accuracy of temperature control.

[0050] In some embodiments, the temperature element 3 further includes an air extraction pipe 38 connected to both sides of each temperature chamber 31, and an air extraction fan 39 is connected to the air extraction pipe 38.

[0051] In this embodiment, each temperature chamber 31 has an exhaust pipe 38 on both sides, and an exhaust fan 39 is connected to the exhaust pipe 38. Thus, when temperature control is required, the exhaust fan 39 can extract cold air from the temperature chamber 31 to improve the precision of temperature control.
