[0002] A reaction vessel, broadly speaking, is a stainless steel container that undergoes physical or chemical reactions. The structure and parameters of the vessel are designed and configured according to different process requirements. Design conditions, processes, inspection, manufacturing, and acceptance must adhere to relevant technical standards to achieve the heating, evaporation, cooling, and low-to-high-speed mixing reaction functions required by the process.

This invention effectively enhances the mixing effect of raw materials, effectively promotes the mixing reaction between raw materials, and greatly improves the efficiency of nanomaterial preparation.

[0004] The existing technology has the following problems:

[0005] The reactor uses multiple stirring mechanisms to stir the internal materials, but the stirring components only agitate the horizontal side of the materials and do not mix the materials above and below each other, resulting in a decrease in mixing efficiency. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5As shown, a reaction vessel device for preparing nanomaterials includes a reaction vessel body 1, a vessel cover 2 fixedly connected to the upper side of the reaction vessel body 1, a support frame 3 fixedly connected to the lower side of the reaction vessel body 1 near the edge, a stirring mechanism 4 fixedly connected to the upper side of the support frame 3, and a material injection pipe 5 fixedly connected to the upper side of the vessel cover 2 near the left side.

[0027] The stirring mechanism 4 includes a movable plate 41, a stirring assembly 45 is fixedly connected to the lower side of the movable plate 41, a number of ring-shaped push rods 44 are fixedly connected to the lower side of the movable plate 41 near the edge, a number of ring-shaped inclined platforms 42 are rotatably connected to the upper side of the power assembly 43 near the edge, and the power assembly 43 is movably installed on the upper side of the lid 2 near the edge.

[0028] It should be noted that the structural design of the reactor body 1, the reactor cover 2, and the feed pipe 5 is consistent with the structural design of the components with the same function in the reference case. The power assembly 43 contains a gear assembly, which is used to drive the inclined platform 42 to rotate. When the inclined platform 42 rotates, it pushes the push rod 44 to move up and down, thereby driving the stirring assembly 45 to move up and down.

[0029] like Figure 4 , Figure 5 As shown, the stirring assembly 45 includes a first motor 451. The upper side of the first motor 451 is fixedly connected to the lower middle part of the moving plate 41. The output end of the first motor 451 is fixedly connected to a round tube 452. The lower side of the round tube 452 is fixedly connected to a rotating frame 453. Four rectangularly distributed crossbars 454 are fixedly connected to the left and right sides of the rotating frame 453 near the upper and lower sides. The outer side of the crossbars 454 is movably sleeved with a stirring frame 455, and two stirring frames 455 are distributed on the left and right sides.

[0030] It should be noted that the first motor 451 drives the round tube 452 to rotate, the round tube 452 rotates, the rotating frame 453 rotates, and the rotating frame 453 rotates, which in turn drives the stirring frame 455 to rotate.

[0031] like Figure 5 As shown, the outer sides of the four crossbars 454 near the rotating frame 453 and the side of the stirring frame 455 near the first motor 451 are all fixedly connected with the first flexible sleeve 456.

[0032] It should be noted that the first flexible sleeve 456 is used to seal the gap between the stirring frame 455 and the crossbar 454 to prevent materials from entering and being difficult to clean. The first flexible sleeve 456 can be made of high-temperature resistant rubber with a Teflon coating. The temperature inside the reactor is usually below 300 degrees Celsius, while some high-temperature resistant rubbers can withstand temperatures above 400 degrees Celsius.

[0033] like Figure 4As shown, a rotating plate 46 is rotatably connected to the outer side of the round tube 452 near the bottom, and a second flexible sleeve 47 is fixedly connected between the upper side of the rotating plate 46 and the inner top of the lid 2.

[0034] It should be noted that the second flexible sleeve 47 is used to seal the hole on the lid 2 through which the round tube 452 passes, so as to avoid air leakage due to poor sealing.

[0035] like Figure 4 As shown, several ring-shaped limiting rods 48 are fixedly connected to the upper side of the lid 2 and the inner upper surface of the lid 2. The side of the moving plate 41 and the outer side of the rotating plate 46 are movably sleeved on the outer side of the limiting rods 48.

[0036] It should be noted that the limiting rod 48 is used to limit the rotating plate 46 and the moving plate 41, so that the rotating plate 46 and the moving plate 41 can only move up and down, but cannot rotate.

[0037] like Figure 4 As shown, ball bearings are rotatably connected to the lower side of several push rods 44.

[0038] It should be noted that the ball bearings are used to reduce the friction between the ramp 42 and the push rod 44, thereby reducing wear between the components.

[0039] like Figure 5 As shown, a second motor 49 is fixedly connected to the lower middle part of the reactor body 1. A transmission rod 410 is fixedly connected to the output end of the second motor 49. Two centrally symmetrical slide rails 411 are fixedly connected to the outer middle part of the transmission rod 410. The stirring frame 455 is slidably connected to the inner side of the slide rail 411 at the middle position of the wall away from the transmission rod 410 and close to the rotating frame 453.

[0040] It should be noted that the second motor 49 is used to drive the transmission rod 410 to rotate. When the transmission rod 410 rotates, it drives the slide rail 411 to rotate. When there is a difference between the rotation speed of the slide rail 411 and the rotation speed of the stirring rack 455, the slide rail 411 will rotate relative to the stirring rack 455, thereby causing the slide rail 411 to push the stirring rack 455 closer to or away from the first motor 451.

[0041] The working principle of this utility model is as follows: First, the power assembly 43 contains a gear assembly to drive the inclined platform 42 to rotate. When the inclined platform 42 rotates, it pushes the top rod 44 to move up and down, thereby driving the stirring assembly 45 to move up and down. The first motor 451 drives the circular tube 452 to rotate. When the circular tube 452 rotates, it drives the rotating frame 453 to rotate. When the rotating frame 453 rotates, it drives the stirring frame 455 to rotate. Through the power assembly 43 driving the inclined platform 42 to rotate, the stirring assembly 45 performs up and down reciprocating motion, thereby making the stirring assembly 45 stir the material while simultaneously turning it up and down, improving the material mixing efficiency. Finally, the first motor 451 drives the circular tube 452 to rotate, and when the circular tube 452 rotates, it drives the top rod 44 to move up and down. The rotating frame 453 rotates, which in turn drives the stirring frame 455 to rotate. The second motor 49 drives the transmission rod 410 to rotate, which in turn drives the slide rail 411 to rotate. When there is a difference between the rotation speed of the slide rail 411 and the rotation speed of the stirring frame 455, the slide rail 411 will rotate relative to the stirring frame 455, thereby causing the slide rail 411 to push the stirring frame 455 closer to or away from the first motor 451. The second motor 49 drives the slide rail 411 to rotate, causing the stirring frame 455 to move closer to or away from the first motor 451. This allows the stirring frame 455 to avoid contacting the inner wall of the reactor body 1 when scraping is not required, thus reducing component wear.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
