Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a vacuum drying equipment, including a frame 1 and a control frame 6 disposed on one side of the frame 1. A door 2 is provided on one side of the frame 1. A detachable trolley mechanism 3 is provided inside the frame 1. The trolley mechanism 3 is used to independently place multiple sets of DC fans in layers. The trolley mechanism 3 includes a frame 31. Multiple sets of support frames 34 are provided on both sides inside the frame 31. Each support frame 34 is provided with a detachable fan mounting frame 32 for mounting multiple sets of DC fans. A circulating fan 8 is also provided inside the frame 1. A resistance heating wire 11 is also provided inside the frame 1 below the circulating fan 8. The resistance heating wire 11 and the circulating fan 8 are both connected to a control host 4. The control host 4 is located in the middle of the control frame 6. Specifically, a temperature control switch is provided on the control host 4. The temperature control switch and the resistance heating wire are connected to the control host 6. The heating wire 11 is electrically connected, which can control the heating temperature of the resistance heating wire 11. At the same time, the control host 4 also transmits data to the display screen 5, which displays temperature and other information. The bottom of the control frame 6 is equipped with an installation chamber 10, which contains a vacuum pump. The vacuum pump is connected to the exhaust pipe 7, and one end of the exhaust pipe 7 is connected to the test chamber in the frame 1. The vacuum pump can be controlled to run, creating a vacuum test environment in the test chamber. The frame 1 on one side of the circulating fan 8 is equipped with an exhaust fan 9, which is connected to the control host 4 and can exhaust the humid air in the test chamber. The bottom of the frame 31 is equipped with high-temperature casters 33, which correspond to the guide groove 14. The guide groove 14 is set on the base frame 12, which is set at the bottom of the test chamber, making it easy to move the frame 31 into or out of the test chamber.

[0019] First, the DC fans are installed on the fan mounting brackets 32. Then, the fan mounting brackets 32 are placed on the corresponding layers of the support frame 34 and positioned. Next, the frame 31 is pushed and moved by the high-temperature casters 33, which are then moved into the test chamber through the guide groove 14. Then, the DC fans of each layer are mechanically connected in series with the ports on the frame 31. The ports on the frame 31 are then connected to the data connection cable. The control host 4 synchronously controls the operation of multiple DC fans. Then, the resistance heating wire 11 and the circulating fan 8 are operated. The circulating fan 8 delivers airflow. When the airflow passes through the resistance heating wire 11, it forms a hot airflow and is delivered into the test chamber, thereby simulating a high-temperature drying environment and allowing the DC fans to undergo a durability test under a high-temperature drying environment.

[0020] After the test is completed, the vacuum pump can be run to discharge the air in the test chamber through the exhaust pipe 7, so that the test chamber is in a vacuum state, and then the durability of the DC fan in the vacuum state can be tested.

[0021] Furthermore, an insulation board 13 is installed in the middle of the base frame 12 to keep the heat in the test chamber warm and prevent the heat from being lost too quickly.

[0022] Please see Figure 5 as well as Figure 6 The fan mounting bracket 32 ​​includes an outer frame 323 and a base plate 321. The base plate 321 is located at the bottom of the outer frame 323 and has positioning mounting ports 322 arranged in an array, which can position and install multiple DC fans. The outer frame 323 is connected to the frame 31 through a locking structure. The two ends of the fixing pin 327 are respectively movably disposed in the guide sleeve 326 and the storage sleeve 324. The guide sleeve 326 and the storage sleeve 324 are respectively disposed on one side surface of the outer frame 323. One end of the fixing pin 327 abuts against the positioning buckle 328, which is disposed on the inner side surface of the frame 31. This can lock and fix the multi-layer fan mounting bracket 32 ​​to the frame 31, thereby improving the stability during DC fan testing. Specifically, the fixing pin 327 is also provided with an adjustment part 325, which can control the movement and positioning of the fixing pin 327. At the same time, the fixing buckle can be inserted into the gap of the limiting part, which is located between the guide sleeve 326 and the storage sleeve 324.

[0023] First, the DC fans are sequentially arrayed and installed in the positioning mounting port 322. Then, the outer frame 323 is moved to the support frame 34 on the frame 31. Next, the fixing pin 327 is moved horizontally within the storage sleeve 324 and the guide sleeve 326 by the adjusting part 325. When the fixing pin 327 abuts against the positioning buckle 328, the fixing pin 327 is pushed down to insert the adjusting part 325 into the gap between the limiting part and the guide sleeve 326. The adjusting part 325 positions the fixing pin 327, and then the fan mounting bracket 32 ​​is fixed in the frame 31.

[0024] When it is necessary to disassemble the fan mounting bracket 32, simply push the fixing pin 327 to separate the fixing pin 327 from the positioning buckle 328.
