[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-6 The utility model provides a technical solution: a germanium chlorination distillation kettle with a pre-oxidation reaction, comprising a shell 1, a support leg 2, a feed port 3, a motor 4, a rotating shaft 5, a rotating cylinder 601, an annular material plate 602, a valve 603, a temperature sensor 604, an exhaust ring 605, a fixed plate 606, a rotating plate 607, a heating wire 7, a connecting rod 801, a swirl fan 802, a push rod 803, an arc rod 804, a scraper 805, and a stirring fan 9.

[0036] Example 1

[0037] The germanium chlorination distillation kettle with pre-oxidation reaction is provided with a pre-oxidation structure, which enables the material to be pre-oxidized through the annular material plate 602 in the upper part of the shell 1, specifically:

[0038] The lower surface of the shell 1 is provided with a supporting leg 2, and also includes a feed port 3, which is installed at the upper end of the shell 1, and a motor 4 is installed at the upper end of the shell 1, and the motor 4 is connected to a rotating shaft 5, and a pre-oxidation structure is installed inside the shell 1, and the pre-oxidation structure can make the material pre-oxidized in the upper part of the inner part of the shell 1 through a rotating plate 607, and the pre-oxidation structure includes a rotating cylinder 601, and the rotating cylinder 601 is rotatably connected to the rotating shaft 5, and an annular material plate 602 is fixedly installed on the outer surface of the rotating cylinder 601, and an exhaust ring 605 is correspondingly arranged above the annular material plate 602, and a valve 603 is connected to the lower end of the exhaust ring 605, and the valve 603 is controlled by a temperature sensor 604, and the temperature sensor 604 is fixedly installed on the upper surface of the inner wall of the shell 1, and the outer surface of the annular material plate 602 is fixedly connected to the inner wall surface of the shell 1, and the outer surface of the rotating shaft 5 is fixedly connected to a rotating plate 607, and a fixed plate 606 is correspondingly installed below the rotating plate 607, and the fixed plate 606 is fixedly installed on the inner wall surface of the shell 1;

[0039] The germanium chlorination distillation kettle with pre-oxidation reaction is used as follows: Figure 1 As shown, the support legs 2 installed on the lower surface of the housing 1 are placed in a suitable position, and then materials are added to the interior of the housing 1 through the feed port 3 installed on the upper surface of the housing 1. When the materials enter the interior, they will first reach the upper surface of the annular material plate 602, as shown in FIG. Figure 2 As shown, the heating wire 7 installed in the inner wall interlayer of the shell 1 is turned on, so that the internal temperature rises. The material will be evenly heated while slowly sliding downward on the annular material plate 602, so that the germanium material can be pre-oxidized, which is convenient for improving the distillation efficiency later. At this time, the material is heated and oxidized, and gas will be generated while the internal temperature rises. At this time, the temperature sensor 604 installed on the lower surface of the inner wall of the shell 1 detects the internal temperature change and controls the valve 603 connected to the lower end of the exhaust ring 605 to open, so that the airflow generated inside will be discharged outward through the exhaust ring 605. When the pre-oxidation is completed, the material continues to move downward. At this time, the motor 4 is turned on, and the motor 4 will rotate the shaft 5, and the shaft 5 will drive the rotating plate 607 to rotate. Since the lower surface of the rotating plate 607 is in contact with the upper surface of the fixed plate 606, and the rotating plate 607 and the fixed plate 606 are both provided with openings, the material slowly moves downward through the opening while the rotating plate 607 rotates and enters the lower half of the shell 1, which is convenient for subsequent distillation.

[0040] Example 2

[0041] The germanium chlorination distillation kettle with pre-oxidation reaction is also provided with a scraping structure, which can prevent the material from hanging on the wall through the scraping bar 805, specifically:

[0042] The rotating shaft 5 is also connected to a scraper structure, which can prevent the material from adhering to the inner wall surface of the shell 1 through a scraper bar 805 while stirring. The scraper structure includes a connecting rod 801, which is fixedly installed on the outer surface of the rotating shaft 5, and push rods 803 are slidably connected at both ends of the connecting rod 801. A swirl fan 802 is installed on the outer surface of the push rod 803, and an arc rod 804 is fixedly installed on the other end of the push rod 803, and a scraper bar 805 is installed on the side surface of the arc rod 804. A heating wire 7 is installed in the inner wall interlayer of the lower half of the shell 1, and a stirring fan 9 is fixedly installed on the outer surface of the rotating shaft 5. The scraper bar 805 is set to a conical structure;

[0043] When the material enters the lower part of the shell 1, the heating wire 7 makes the material distilled, and at the same time the shaft 5 drives the stirring fan 9 to rotate, making the distillation reaction more uniform. When the material is distilled, the inner wall temperature is high, which makes it easy for the material distillation residue to adhere to the inner wall of the shell 1, affecting the efficiency of the distillation. Figure 6 As shown, the connecting rod 801 fixedly installed on the outer surface of the rotating shaft 5 is driven to rotate, so that the swirl fan 802 installed on the outer surface of the push rod 803 generates an opposite impact force with the material during stirring, so that the swirl fan 802 drives the push rod 803 to expand outward, so that the push rod 803 pushes the arc rod 804 close to the inner wall of the outer shell 1, so that the scraper bar 805 fits with the inner wall of the outer shell 1, and the scraper bar 805 scrapes the inner wall of the outer shell 1 while rotating to prevent the material from adhering to the inner wall and affecting the distillation effect.

[0044] Working principle: When using the germanium chlorination distillation kettle with pre-oxidation reaction, a pre-oxidation structure is provided, which can slowly heat the material on the annular material plate 602 and exhaust the gas through the exhaust ring 605. A scraping structure is also provided, which can prevent the material from adhering to the inner wall surface of the outer shell 1 through the scraper bar 805 while stirring, thereby increasing the overall practicality.
