[0016] 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.

[0017] Please see Figures 1-4 An embodiment of this utility model provides an apparatus for preparing nanomaterials by liquid phase method, comprising a vessel body 1, a mixing mechanism 6 provided on the top of the vessel body 1, a control box 7 fixedly installed on the top of the vessel body 1, the mixing mechanism 6 comprising a mixing barrel 61, a mixing chamber 62, a first partition 63, a collar 64, mixing blades 65 and a first connecting hole 66, the mixing barrel 61 fixedly installed on the upper end of the vessel body 1, a first servo motor 2 installed on the upper end of the mixing barrel 61, a stirring rod 3 fixedly connected to the lower end of the first servo motor 2, two sets of feed inlets 4 opened on the upper side of the mixing barrel 61, a discharge port 5 fixedly installed on the bottom of the vessel body 1, a mixing chamber 62 opened inside the mixing barrel 61, a first partition 63 provided on the inner wall of the mixing chamber 62, a collar 64 provided on the outer side of the stirring rod 3, two sets of mixing blades 65 provided on the front and rear sides of the collar 64, and a first connecting hole 66 equidistantly opened on the surface of the first partition 63; This device, through the design of the mixing mechanism 6, solves the problem that directly pouring raw materials into the device without sufficient mixing can easily lead to the aggregation of nanoparticles, resulting in a slow reaction process.

[0018] Furthermore, the control box 7 is internally equipped with a linkage mechanism 8, which includes a second servo motor 81, a movable slot 82, a first bevel gear 83, a second bevel gear 84, a second partition 85, and a second connecting hole 86. The second servo motor 81 is fixedly installed inside the control box 7. The movable slot 82 is opened inside the mixing tank 61. The output end of the second servo motor 81 is fixedly connected to the first bevel gear 83. The second bevel gear 84 is rotatably connected to the bottom of the first partition 63 inside the mixing tank 61. The second bevel gear 84 meshes with the first bevel gear 83. The inner wall of the second bevel gear 84 is fixedly connected to the second partition 85. The second partition 85 has second connecting holes 86 equidistantly opened inside, with the diameters of the second connecting holes 86 and the first connecting holes 66 being the same, and their initial positions being staggered. Figure 4 As shown, this structure is used to drive the first bevel gear 83 to rotate by starting the second servo motor 81. The first bevel gear 83 meshes with the second bevel gear 84, driving the second bevel gear 84 and the second partition 85 to rotate. This causes the second connecting hole 86 at the second partition 85 to overlap with the first connecting hole 66 at the first partition 63, allowing the material inside the mixing chamber 62 to enter the reactor body 1 through the first connecting hole 66 and the second connecting hole 86 for subsequent processing.

[0019] Furthermore, the feed inlet 4 is connected to the interior of the mixing chamber 62, the outer surface of the first partition 63 is fixedly connected to the inner wall of the mixing chamber 62, the collar 64 is located on the inner wall of the surface of the first partition 63 and is fixedly connected to the stirring rod 3, and the inner ends of the two sets of mixing blades 65 are fixedly connected to the collar 64. Figure 2 As shown, this structure is used to pour raw materials into the mixing chamber 62 from two sets of feed ports 4 respectively. After pouring, the first servo motor 2 is started to drive the two sets of mixing blades 65 at the collar 64 to rotate, so that the raw materials inside are fully mixed.

[0020] Furthermore, scrapers 67 are fixedly connected to the bottom of the two sets of mixing blades 65. The cross-sections of the two sets of scrapers 67 are triangular, and they face opposite directions. Figure 2 As shown, this structure is used to clean the raw material on the surface of the first partition 63 by means of the scraper 67 at the mixing blade 65, which drives the scraper 67 at the bottom when the mixing blade 65 rotates.

[0021] Furthermore, a limiting ring 87 is fixedly connected to the outer surface of the second bevel gear 84, and a slide rail adapted to the limiting ring 87 is provided inside the mixing barrel 61. Figure 4 As shown, this structure is used to enable the second bevel gear 84 to drive the second partition 85 to rotate stably within the mixing tank 61 via the limiting ring 87, thereby improving the stability of the device.

[0022] Furthermore, heating wires 9 are installed inside the mixing tank 61, and the heating wires 9 are arranged in a spiral shape. For example... Figure 3 As shown, this structure is used to preheat the interior of the mixing chamber 62 via the heating wire 9, thereby improving reaction efficiency.

[0023] Furthermore, a control panel 10 is fixedly mounted on the outer surface of the control box 7. The control panel 10 is electrically connected to the heating wire 9 and the second servo motor 81. For example... Figure 3 As shown, this structure is used to control the temperature of the heating wire 9 via the control panel 10, and to control the start and stop of the second servo motor 81.

[0024] Working principle: When using, such as Figure 1 and Figure 2 As shown, the raw materials are poured into the mixing chamber 62 from the two sets of feed inlets 4. After pouring, the first servo motor 2 is started, driving the two sets of mixing blades 65 at the collar 64 to rotate, so that the raw materials inside are fully mixed. Figure 3 As shown, the temperature of the heating wire 9 is simultaneously controlled via the control panel 10 to preheat the interior of the mixing chamber 62. Figure 2 and Figure 4 As shown, after thorough mixing, the second servo motor 81 is started to drive the first bevel gear 83 to rotate. The first bevel gear 83 meshes with the second bevel gear 84, driving the second bevel gear 84 and the second partition 85 to rotate. This causes the second connecting hole 86 at the second partition 85 to overlap with the first connecting hole 66 at the first partition 63. When the mixing blade 65 rotates, it drives the scraper 67 at the bottom. The scraper 67 pushes the raw material on the surface of the first partition 63, allowing the material inside the mixing chamber 62 to enter the reactor body 1 through the first connecting hole 66 and the second connecting hole 86 for subsequent processing. The above is the complete working principle of this utility model.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
