This method is greatly affected by factors such as the fluidity and particle size of the catalyst, resulting in obvious differences in the amount of catalyst added each time, thus making the reaction effect unstable, the product quality uneven, and the defective rate high. In addition, due to the lack of an effective sealing structure, during the addition of the catalyst, good isolation cannot be achieved between the storage bin and the reaction vessel, and it is easy for the gas in the reaction vessel to enter the catalyst storage container.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Such as Figures 1-7As shown in the figure, a catalyst adding device for the production of sealed chemical products provided by the utility model includes a silo 1, on which a machine base 2 is fixedly installed. On the machine base 2, a reduction motor 3 is fixedly installed. The reduction motor 3 is electrically connected to an external main controller through a cable. A cylinder 4 is fixedly installed on the reduction motor 3. The cylinder 4 is connected to an external air pump through an air pipe. A stirring shaft 5 is fixedly installed inside the output end of the reduction motor 3. One end of the stirring shaft 5 extends into the silo 1 and is fixedly installed with a plurality of stirring blades 6. The lower end of the silo 1 is fixedly installed with a bottom pipe 7. The lower end of the bottom pipe 7 is fixedly installed with a blanking pipe 8. A rotating disk 9 is movably installed inside the blanking pipe 8. A turntable 10 is movably installed inside the blanking pipe 8 below the rotating disk 9. A bottom plate 11 is movably installed inside the blanking pipe 8 below the turntable 10.
[0025] As Figures 2-4 shown, a shaft hole 12 is opened inside the stirring shaft 5. A guiding slope panel 13 is fixedly installed inside the bottom pipe 7. A first sealing bearing 14 is fixedly installed at the middle position inside the guiding slope panel 13. A first blanking port 15 is also opened at the bottom inside the guiding slope panel 13. The bottom pipe 7 facilitates the connection between the blanking pipe 8 and the silo 1. The setting of the guiding slope panel 13 and the first blanking port 15 can realize the guiding blanking of the catalyst inside the silo 1.
[0026] As Figures 2-7As shown in the figure, a plurality of rotating grooves 16 are formed inside the blanking pipe 8. The formation of a plurality of rotating grooves 16 inside the blanking pipe 8 can provide conditions for the axial movement of the rotating tray 9. Inside the blanking pipe 8 at a position below one of the rotating grooves 16, a plurality of sliding grooves 17 are also formed. The formation of the sliding grooves 17 can provide conditions for the vertical radial movement of the bottom plate 11 inside the blanking pipe 8. A plurality of storage cavities 18 are formed inside the rotating tray 9. The storage cavities 18 are used to receive and store the catalyst conveyed by the first blanking port 15. A key groove 19 is formed in the middle of the rotating tray 9. A plurality of fixing rings 20 are fixedly installed on the outside of the rotating tray 9. The outside of the fixing rings 20 is also rotatably installed in the corresponding rotating grooves 16. On the turntable 10, a plurality of storage cylinders 21 with the same number as the storage cavities 18 are fixedly installed. In the middle position at the upper end of the turntable 10, a key shaft 22 is fixedly installed. At the upper end of the key shaft 22, a first rotating shaft 23 is fixedly installed. At the middle position at the lower end of the turntable 10, a second rotating shaft 24 is fixedly installed. The upper end of the key shaft 22 is inserted into the key groove 19. The upper end of the first rotating shaft 23 passes through the shaft hole 12 and extends to a position above the stirring shaft 5. Moreover, on the outside of the first rotating shaft 23, a key block is fixedly installed and inserted into the inside of the shaft hole 12. After the key shaft 22 is inserted into the key groove 19, it can cooperate with the stirring shaft 5 and the first rotating shaft 23 to synchronously drive the rotation of the rotating tray 9, the turntable 10, and the storage cylinders 21, so as to facilitate the storage of a fixed amount of catalyst in the cavity formed by the storage cavity 18 and the storage cylinder 21 and quantitatively add it to the reaction vessel. A plurality of sliding blocks 25 are fixedly installed on the outside of the bottom plate 11. A second blanking port 26 is formed inside the bottom plate 11. One side of the sliding blocks 25 is slidably installed in the corresponding sliding grooves 17. At the lower end of the bottom plate 11, a second sealing bearing 27 is fixedly installed. The inner ring of the second sealing bearing 27 is inserted on the second rotating shaft 24. At the upper end of the first rotating shaft 23, a linear bearing 28 is rotatably installed. One end of the piston rod of the air cylinder 4 is fixedly installed in the linear bearing 28. The cooperation of the air cylinder 4 with the linear bearing 28 and the first rotating shaft 23 can realize that while the reduction motor 3 drives the stirring shaft 5, the first rotating shaft 23, the rotating tray 9, and the turntable 10, the turntable 10 can be driven to drive a plurality of storage cylinders 21 to lift in the corresponding storage cavities 18 by lifting the first rotating shaft 23, so as to adjust the storage volume of the storage cavities 18 and the storage cylinders 21, and further quickly and synchronously adjust the single-time blanking amount of the catalyst.
[0027] It should be noted that the present utility model is a catalyst adding device for the production of sealed chemical products. After the device is started, the external main controller sends an instruction to the reduction motor 3, and the reduction motor 3 starts to drive the stirring shaft 5 to rotate by a certain angle and then stop. As a result, the stirring blades 6 installed on the stirring shaft 5 rotate accordingly to stir the catalyst in the storage bin 1, avoiding blockage during material feeding. While the reduction motor 3 drives the stirring shaft 5 to rotate, it also drives the first rotating shaft 23 to rotate through the cooperation between the shaft hole 12 and the key block on the outer side of the first rotating shaft 23. Since the key shaft 22 is inserted into the key groove 19 of the rotating tray 9, when the first rotating shaft 23 rotates, it will synchronously drive the key shaft 22, the turntable 10, and the storage cylinder 21 to rotate. During the stirring process, the catalyst in the storage bin 1 relies on its own gravity, and under the guidance of the material guiding slope panel 13 in the bottom pipe 7, it falls through the first material outlet 15 into the cavity formed by the storage cavity 18 of the rotating tray 9, the storage cylinder 21, and the bottom plate 11 for temporary storage. Then, the cavity formed by the storage cavity 18 of the rotating tray 9, the storage cylinder 21, and the bottom plate 11, which pre-stores the catalyst, rotates to the position above the second material outlet 26, so that the catalyst falls into the reaction vessel;
[0028] When adjusting the material feeding amount according to production requirements, the external air pump supplies air or exhausts air to the air cylinder 4. The piston rod of the air cylinder 4 drives the linear bearing 28 to move vertically, and then drives the first rotating shaft 23 to rise and fall. When the first rotating shaft 23 rises and falls, it drives the turntable 10 and the storage cylinder 21 to rise and fall in the storage cavity 18 through the key shaft 22, changing the volume between the storage cavity 18 and the storage cylinder 21, realizing the adjustment of the single - time material feeding amount of the catalyst. And the turntable 10 drives the bottom plate 11 to rise and fall synchronously with the turntable 10 through the cooperation of the second rotating shaft 24 at the lower end and the second sealing bearing 27, so as to seal the cavity of the storage cylinder 21 that is not above the slider 25, ensuring the quantitative storage and feeding of the catalyst.
