DETAILED DESCRIPTION
[0019] 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.
[0020] Please see Figs. 1 to 4 This utility model provides a technical solution: a multi-radiation protection mechanism for a synthetic heat chamber, including a synthetic heat chamber 1, a protection component 2 and a stable conveying component 3 inside the synthetic heat chamber 1, and a control panel 4 on one side of the synthetic heat chamber 1. The protection component 2 includes an electric push rod 21, which is fixedly installed inside the synthetic heat chamber 1. A first shielding door 22 is slidably connected to the synthetic heat chamber 1 through a sliding groove inside it. A second shielding door 24 and a third shielding door 25 are also slidably connected to the synthetic heat chamber 1 through a sliding groove inside it. Observation devices are fixedly installed inside the first shielding door 22, the second shielding door 24, and the third shielding door 25. The output shaft of an electric push rod 21 is fixedly installed on one side of the observation window 23, the first shielding door 22, the second shielding door 24 and the third shielding door 25. The stable conveying component 3 includes a motor 34, which is fixedly installed on one side of the synthesis heat chamber 1. A threaded rod 31 is fixedly installed at one end of the output shaft of the motor 34. The threaded rod 31 is rotatably connected inside the synthesis heat chamber 1. The synthesis heat chamber 1 is slidably connected to a moving frame 32 through a sliding groove provided inside it. The moving frame 32 is threadedly connected to the threaded rod 31 through a threaded hole provided inside it. A support frame 35 is fixedly installed on one side of the moving frame 32. A clamp 33 is fixedly installed on the top surface of the support frame 35. The support frame 35 is located between the first shielding door 22 and the second shielding door 24.
[0021] When materials need to be fed into the synthesis heating chamber 1, the electric push rod 21 of the first shielding door 22 is used to open the first shielding door 22 partially, thereby exposing the support frame 35. The tank carrying the material is then placed on the support frame 35, and the clamp 33 is used to clamp and limit the tank. The electric push rod 21 of the first shielding door 22 is then used to close the first shielding door 22. The electric push rod 21 of the second shielding door 24 is then used to open the second shielding door 24 partially. The motor 34 is then started to rotate the threaded rod 31, thereby moving the moving frame 32 and the support frame 35. When the support frame 35 is between the second shielding door 24 and the third shielding door 25, the electric push rod 21 of the second shielding door 24 is used to close the second shielding door 24. Simultaneously, the electric push rod 21 of the third shielding door 25 is used to open the third shielding door 25 partially. After the carrier frame 35 is fully inserted into the synthesis heat chamber 1, the third shielding door 25 is closed, thus completing the material conveying. The tank can then be removed by the robotic arm installed inside the synthesis heat chamber 1. After the material is removed, the third shielding door 25 is partially opened, and the motor 34 is started and its output shaft is reversed, causing the carrier frame 35 to move backward. The motor 34 is then turned off and the third shielding door 25 is closed when the carrier frame 35 is between the third shielding door 25 and the second shielding door 24. The radiation treatment equipment installed inside the synthesis heat chamber 1 then processes the carrier frame 35, the clamp 33, and the moving frame 32. After processing, the second shielding door 24 is partially opened, and the motor 34 is started and its output shaft is reversed, causing the carrier frame 35 to reset. The second shielding door 24 is then closed. While the carrier frame 35 is resetting, the moving frame 32 always keeps the inner wall groove of the synthesis heat chamber 1 sealed, thus preventing internal radiation leakage and reducing the risk of radiation exposure to workers.
