Detailed Implementation
[0024] 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.
[0025] This utility model provides, for example Figure 1-5 The stirring device shown is for the analysis of petrochemical products based on cucurbituril, including a body 2 and a control panel 1 installed inside the body 2;
[0026] The internal structure of the body 2 contains a drive motor 9;
[0027] A stirring rod 4 is fixedly connected to the lower outer wall of the drive motor 9;
[0028] Stirring blades 5 are fixedly connected to the circular outer walls of both ends of the stirring rod 4 to drive the reagent to rotate. A heating seat 17 is provided on the lower inner wall of the machine body 2. A container 6 is provided on the upper side of the heating seat 17 to store the chemical reagent to be stirred. A drive shaft 3 is fixedly connected to the lower outer wall of the drive motor 9 to drive the stirring rod 4 to rotate. When the operator starts the device, the container 6 containing the reagent is first placed under the stirring rod 4. Then, the control panel 1 issues a command to make the drive motor 9 move down, so that the stirring blades 5 are inserted into the bottom of the container 6. Then the drive motor 9 starts to work. The rotation of the drive motor 9 is transmitted to the stirring rod 4 through the drive shaft 3, so that it starts to rotate. The stirring blades 5 rotate in the container 6, thereby generating liquid flow and promoting the full mixing of chemical reagents. The corresponding chemical reaction is carried out by cucurbituril group against xylene isomers. The heating seat 17 heats the reagent in the container 6 through heat conduction to ensure that the reaction is carried out at a suitable temperature and improve the reaction efficiency.
[0029] A discharge pipe 11 is provided on the upper side of the container 6. A guide pipe 10 is fixedly connected to the upper end of the discharge pipe 11. A feeding hopper 13 is fixedly connected to the other end of the guide pipe 10 to add additional chemical reagents. When it is necessary to add additional reaction reagents into the container 6, the prepared reagents can be added through the feeding hopper 13. The feeding hopper 13 can guide the reagents through the guide pipe 10 into the discharge pipe 11 and then add them into the container 6.
[0030] like Figure 4 and Figure 4 As shown, a groove 12 that runs through the left and right sides is provided inside the outer wall of the right end of the machine body 2. A fixed support 16 is provided on the left side of the feeding hopper 13 to limit the position of the guide tube 10. A support spring 14 is fixedly connected between the lower circular outer wall of the fixed support 16 and the lower inner wall of the groove 12 to pre-limit the position of the guide tube 10. Sliding grooves 15 are provided on the inner walls of both the front and rear ends of the groove 12.
[0031] During the addition of additional reagents, the feeding hopper 13 can be gripped and moved up and down. During this up-and-down movement, the support spring 14 will be pressed down, increasing the stability of the movement. At the same time, when the fixed support 16 is not moving up and down, the support spring 14 can also use its rebound force to press the fixed support 16 against the upper inner wall of the groove 12, thus restricting the position of the fixed support 16. Furthermore, by pulling the feeding hopper 13 laterally, the guide tube 10 can be moved laterally inside the fixed support 16 to adjust the position of the discharge tube 11 for adding reagents. Simultaneously, under the restriction of the fixed support 16, the guide tube 10 can be rotated to more flexibly adapt to containers 6 of different sizes for adding reagents at different positions.
[0032] like Figure 4 and Figure 5 As shown, the inner walls of the front and rear ends of the groove 12 are fixedly connected to the left side with heat insulation curtains 19 to reduce the temperature diffusion inside the body 2. The outer circular walls of the front and rear ends of the fixed support 16 are fixedly connected to sliders that are slidably connected inside the slide groove 15. The two heat insulation curtains 19 are in contact but not fixed. The guide tube 10 can rotate clockwise and counterclockwise inside the fixed support 16.
[0033] When the guide tube 10 moves up and down, the sliders at the front and rear ends of the fixed support 16 will move up and down under the restriction of the slide groove 15 to ensure stability during movement and avoid left and right swaying. When the guide tube 10 moves, it will push the insulation curtains 19 on the front and rear sides to the front and rear sides. After the insulation curtains 19 made of rubber material are pushed open, they will gradually return to their original position and cover the position of the groove 12 again to perform the insulation operation.
[0034] like Figure 1 and Figure 2As shown, the machine body 2 is equipped with a transmission mechanism 8 to drive the drive motor 9 to move up and down. The machine body 2 is equipped with a cabinet door 18 to cover the front opening of the machine body 2. Support legs 7 are fixedly connected to the four corners of the lower outer wall of the machine body 2.
[0035] The transmission mechanism 8 can drive the drive motor 9 to move up and down to adjust the vertical height of the stirring blade 5. When the stirring blade 5 moves up to the maximum position, it can ensure that the container 6 can be picked up and put down normally. When the stirring blade 5 descends to the maximum distance, it can fully mix and stir the reagent in the container 6. The support feet 7 can support the machine body 2 to ensure the stability of the machine body 2.
[0036] like Figure 1 and Figure 2 As shown, a handle is provided on the front outer wall of the cabinet door 18 to drive the cabinet door 18 to move up and down. The cabinet door 18 is transparent. The transmission mechanism 8 and the drive motor 9 are electrically connected to the power supply inside the body 2.
[0037] During the mixing process, the cabinet door 18 needs to be pulled down using the handle to ensure the sealing of the mixing space, thereby reducing temperature diffusion and preventing interference from external factors that could lead to errors in the chemical reaction. The transparent cabinet door 18 allows observation of the internal mixing process and material state without opening it. This facilitates real-time monitoring of the mixing effect and the progress of the chemical reaction, enabling timely adjustments. Connecting the transmission mechanism 8 and the drive motor 9 to the internal power supply of the machine body 2 allows for centralized control, simplifying design and maintenance.
[0038] The implementation principle of this embodiment is as follows: When the operator starts the device, the container 6 containing the reagent is first placed under the stirring rod 4. Then, the control panel 1 issues a command to move the drive motor 9 downward, extending the stirring blade 5 into the bottom of the container 6. Subsequently, the drive motor 9 starts working, and the rotation of the drive motor 9 is transmitted to the stirring rod 4 through the drive shaft 3, causing it to start rotating. The stirring blade 5 rotates inside the container 6, thereby generating liquid flow and promoting the full mixing of chemical reagents. The corresponding chemical reaction is carried out by the cucurbituril group against the xylene isomer. The heating seat 17 heats the reagent in the container 6 through heat conduction, ensuring that the reaction is carried out at a suitable temperature and improving the reaction efficiency. When it is necessary to add additional reaction reagents to the container 6, the prepared reagents can be added through the feeding hopper 13. The feeding hopper 13 can guide the reagents through the guide pipe 10 to the discharge pipe 11 before adding them into the container 6.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
