Description

Technical Field

[0001] This utility model relates to the technical field of stirring devices for reaction vessels, specifically a stirring device for a chemical reaction vessel. Background Technology

[0002] A chemical reactor stirring device typically consists of a stirrer, a motor, a transmission mechanism, and a support structure. The stirrer is the core component; its rotation creates a stirring effect, promoting the mixing and reaction of reactants. The motor provides power, driving the stirrer to rotate and mix the chemical raw materials for the reaction.

[0003] Existing technology typically uses bolts and other parts to fix the top cover and body of the reactor together. The internal condition of the reactor is then observed through a window on the reactor body, which is necessary to observe the internal condition of the reactor body except during the initial use. Although the small window has a sealing function, the size of the window limits the range of observation of the inner wall of the reactor body, making it difficult to observe. Furthermore, when it is necessary to inspect and observe the internal condition of the reactor body after use, it is necessary to disassemble bolts and other fasteners, which is a cumbersome and inconvenient process.

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. Example 1

[0021] Please see Figures 1-2 This utility model discloses a stirring device for a chemical reaction vessel, comprising a support frame 1, a lower vessel body 2 installed in the middle of the support frame 1, a connecting frame 3 installed on the outer surface of the lower vessel body 2, a lifting assembly 4 installed on the top surface of the support frame 1, the lifting assembly 4 including cylinders 5, the cylinders 5 being equidistantly installed on the top surface of the support frame 1, an extension plate 6 installed on the top surface of the cylinders 5, an upper cover 7 corresponding to the lower vessel body 2 installed on the inner wall of the extension plate 6, a closing ring 8 installed on the outer surface of the upper cover 7, an input pipe 9 connected to the inner wall of the upper cover 7, a motor 10 installed on the upper part of the upper cover 7, a transmission rod 11 installed at the bottom end of the motor 10, a stirring rod 12 installed at the lower part of the transmission rod 11, a limiting ring 13 installed on the outer surface of the stirring rod 12, and a limiting plate 14 installed in the middle of the limiting ring 13.

[0022] The inner wall of the middle part of the support frame 1 is fixedly connected to the outer surface of the lower vessel body 2. The connecting frame 3 consists of four rectangular arrays that are equidistantly fixed on the outer surface of the lower vessel body 2. The cylinder 5 consists of four rectangular arrays that are equidistantly fixed on the top surface of the support frame 1.

[0023] The output end of cylinder 5 is fixedly connected to the bottom surface of extension plate 6, and the inner wall of extension plate 6 is fixedly connected to the outer surface of top cover 7.

[0024] All parts of the stirring device of the chemical reactor are securely installed, especially the fixed connection between the support frame 1 and the lower reactor body 2, and the equidistant installation of the cylinder 5 on the top surface of the support frame 1. Simultaneously, check whether the closing rings 8 are engaged to ensure the seal between the upper cover 7 and the lower reactor body 2. Start the cylinder 5; the output end of the cylinder 5 drives the extension plate 6 and the upper cover 7 downwards until the upper cover 7 completely covers the opening of the lower reactor body 2. At this point, the two closing rings 8 are fully engaged, forming a sealed environment. Example 2

[0025] Based on the above embodiment 1, please refer to Figures 3-5 There are two closed rings 8, which mesh with each other. The top surface of one closed ring 8 is fixedly connected to the bottom surface of the upper cover 7, and the bottom surface of the other closed ring 8 is fixedly connected to the top surface of the lower vessel 2.

[0026] The inner wall of the input pipe 9 is connected to the inner wall of the upper cover 7, the bottom surface of the motor 10 is fixedly connected to the top surface of the upper cover 7, and the output end of the motor 10 is fixedly connected to the top end of the transmission rod 11.

[0027] The outer surfaces of the transmission rod 11 are rotatably connected to each other. The transmission rod 11 is in a regular cross shape. The outer surface of the transmission rod 11 meshes with the inner wall of the stirring rod 12. The outer surface of the stirring rod 12 is fixedly connected to the inner wall of the limiting ring 13.

[0028] The outer surface of the limiting ring 13 is rotatably connected to the inner wall of the limiting plate 14, and the outer surface of the limiting plate 14 is fixedly connected to the inner wall of the lower vessel 2.

[0029] The reactants are added into the vessel through the inlet pipe 9. Since the inlet pipe 9 is connected to the inner wall of the upper cover 7, the reactants can smoothly enter the lower vessel 2. The motor 10 is started, and its output drives the transmission rod 11 to rotate. Because the transmission rod 11 is in a regular cross shape and meshes with the inner wall of the stirring rod 12, the rotation of the transmission rod 11 drives the stirring rod 12 to stir within the lower vessel 2. Simultaneously, the limiting ring 13 and the limiting plate 14 ensure the stability of the stirring rod 12 during the stirring process.

[0030] The working principle and usage process of this utility model are as follows: First, ensure that all parts of the stirring device of the chemical reaction vessel are securely installed, especially the fixed connection between the support frame 1 and the lower vessel body 2, and the equidistant installation of the cylinder 5 on the top surface of the support frame 1. Simultaneously, check whether the closing ring 8 is in an engaged state to ensure the sealing between the upper cover 7 and the lower vessel body 2.

[0031] Lowering and sealing stage: Activate cylinder 5. The output end of cylinder 5 drives the extension plate 6 and the upper cover 7 to move downwards until the upper cover 7 completely covers the opening of the lower vessel 2. At this time, the two closing rings 8 are fully engaged, forming a sealed environment.

[0032] Material input: The reactants are added into the reactor body through the input pipe 9. Since the input pipe 9 is connected to the inner wall of the upper cover 7, the materials can smoothly enter the lower reactor body 2.

[0033] Stirring stage: Start motor 10, and the output of motor 10 drives the transmission rod 11 to rotate. Since the transmission rod 11 is in a regular cross shape and meshes with the inner wall of the stirring rod 12, the rotation of the transmission rod 11 will drive the stirring rod 12 to stir within the lower vessel 2. At the same time, the limiting ring 13 and the limiting plate 14 ensure the stability of the stirring rod 12 during the stirring process.

[0034] Reaction complete: Once the chemical reaction is complete, turn off motor 10 and lift the top cover 7 using cylinder 5 to remove the reaction products.
