However, manual feeding is discontinuous, and the amount and interval of each addition are different, which makes the reaction inside the reactor unstable and often accompanied by side reactions. The occurrence of side reactions will affect the main reaction inside the reactor, resulting in waste of reagents and thus affecting the output of the target product. At the same time, side reactions will produce toxic and harmful gases, which will deteriorate the working environment and affect the health of operators. Utility Model Content

[0017] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0018] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0019] Example 1:

[0020] Please see Figures 1 to 5 This utility model provides a technical solution: a protective device for the feed inlet of a reactor, installed on the reactor body 1, characterized in that it includes: The protective cover 3 is connected to the inlet 2 on the reactor body 1. The protective cover 3 is connected to the inlet 2, and a liquid material inlet 5 is connected to the protective cover 3. The liquid material inlet 5 is connected to the solid material inlet 4. A connecting pipe 7 is provided at the lower end of the solid material inlet 4, and the end of the connecting pipe 7 away from the solid material inlet 4 is connected to the liquid material inlet 5. Solid reactants and liquid reactants are fed separately through the solid material inlet 4 and the liquid material inlet 5. A cover plate 6 is rotatably connected to the upper end of the solid material inlet 4, and the upper end of the solid material inlet 4 is sealed by the cover plate 6. A cover plate 6 is installed at the upper end of the solid material inlet 4 to seal the solid material inlet 4 and prevent toxic gases inside the reactor body 1 from being discharged in large quantities through the solid material inlet 4.

[0021] A partition assembly is used to isolate the connection between the solid material inlet 4 and the liquid material inlet 5. The partition assembly includes a storage cavity 8 disposed at the connection between the solid material inlet 4 and the liquid material inlet 5. The storage cavity 8 is connected to the connecting pipe 7, and a first clearance groove 9 is provided inside the storage cavity 8. A partition 10 is slidably arranged inside the first clearance groove 9. An automatic telescopic cylinder 11 is installed on the outside of the storage cavity 8 at a position corresponding to the partition 10. The output end of the automatic telescopic cylinder 11 passes through the side wall of the storage cavity 8 and is connected to the end of the partition 10. When injecting solid reactant into the reactor body 1, first activate the automatic telescopic cylinder 11. The automatic telescopic cylinder 11 pushes the baffle 10 to block the connecting pipe 7 to prevent toxic gases from being released from the reactor body 1. Then rotate the cover plate 6 to inject material into the solid material inlet 4. After the injection is completed, the end of the solid material inlet 4 is blocked by the cover plate 6. Activate the automatic telescopic cylinder 11 to pull the baffle 10 back to its original position. At this time, the solid reactant falls into the reactor body 1.

[0022] A liquid material injection gun 14 is inserted into the upper end of the liquid material inlet 5. A threaded fixing sleeve 13 is fitted on the outside of the liquid material injection gun 14 corresponding to the upper end of the liquid material inlet 5. The threaded fixing sleeve 13 is screwed to the liquid material inlet 5. The liquid material injection gun 14 is connected to the liquid material inlet 5 by the threaded fixing sleeve 13. The liquid reaction material is discharged into the reactor body 1 through the liquid material injection gun 14. The liquid material injection gun 14 can also seal the top of the liquid material inlet 5 to prevent the leakage of toxic gas.

[0023] A dispersion component is disposed inside the reactor body 1 at the lower end corresponding to the liquid material inlet 5, and is used to disperse liquid reaction materials. The dispersion component includes a slidably disposed dispersion plate 21. The shape of the protective cover 3 is designed so as not to affect the entry of the liquid that has been dispersed by the dispersion plate 21 into the reactor. For example, the angle between the side and the top surface of the protective cover 3 can be a right angle, an acute angle or an obtuse angle.

[0024] A mounting plate 20 is installed at the top of the reactor body 1, corresponding to the lower end of the liquid material inlet 5. The dispersing plate 21 is slidably disposed inside the mounting plate 20, and a second return spring 22 is provided between the inner wall of the mounting plate 20 and the end of the dispersing plate 21. The dispersion plate 21 is equipped with multiple sets of nozzles, which are spread out at a certain angle so that the droplets / fine liquid streams can be dispersed and sprayed, which helps to increase the contact area. When the liquid reactant is injected, the slidingly set dispersion plate 21 extends to disperse the liquid reactant, increasing the contact area between the liquid reactant and the solid reactant. On the one hand, this allows the reagent to be more evenly mixed with the material, and on the other hand, it can increase the reaction rate. A control component is provided on the liquid material inlet 5 to control the extension and retraction of the dispersing plate 21.

[0025] The control component includes a limiting groove 15 opened on the outer surface of the liquid material inlet 5 at a position corresponding to the lower end of the threaded fixing sleeve 13, and a limiting block 16 is slidably arranged inside the limiting groove 15; A first reset spring 17 is provided between the upper end of the limiting block 16 and the top end of the limiting groove 15; A through hole 18 is provided between the interior of the limiting groove 15 and the interior of the mounting plate 20. A pull rope 19 is provided inside the through hole 18. The two ends of the pull rope 19 are respectively connected to the end of the dispersing plate 21 and the lower end of the limiting block 16. The elastic force of the first return spring 17 is greater than the elastic force of the second return spring 22; The liquid material injection gun 14 is installed onto the liquid material inlet 5 via the threaded fixing sleeve 13. During installation, the liquid material injection gun 14 can block the upper end of the liquid material inlet 5. When the threaded fixing sleeve 13 abuts against the limiting block 16, the limiting block 16 moves down. At this time, the elastically set dispersion plate 21 is no longer pulled by the pull rope 19. The dispersion plate 21 is ejected to the lower end of the liquid material inlet 5 by the force of the second reset spring 22, and disperses the liquid reaction material discharged from the liquid material injection gun 14.

[0026] The upper end of the protective cover 3 is provided with multiple sets of spaced toxic gas exhaust components 12, each of which is connected to the interior of the protective cover 3; the other end of the toxic gas exhaust component 12 is connected to the alkaline solution.

[0027] The protective cover 3 is made of transparent material, and a lighting device is provided at the top of the interior of the protective cover 3; The transparent material and lighting device allow direct observation of the material reaction inside the reactor body 1 through the protective cover 3.

[0028] The specific method is as follows: Solid reactant material is injected into the reactor body 1 through the cooperation of solid material inlet 4 and connecting pipe 7. Before injection, the automatic telescopic cylinder 11 is activated, which pushes the baffle 10 to extend. When the baffle 10 extends to the other end of the first clearance groove 9, the baffle 10 blocks the connecting pipe 7. After the connecting pipe 7 is cut off, the toxic gas inside the reactor body 1 cannot be discharged. Then, the cover plate 6 is rotated to inject material into the solid material inlet 4. After injection, the end of the solid material inlet 4 is blocked by the cover plate 6. Then, the automatic telescopic cylinder 11 is activated, which pulls the baffle 10 to reset. At this time, the connecting pipe 7 is restored to unobstructed flow, and the solid reactant material falls into the reactor body 1 through the connecting pipe 7. Since the end of the solid material inlet 4 is blocked by the cover plate 6, the gas inside the reactor body 1 cannot be discharged.

[0029] When injecting liquid reaction materials, first install the liquid material injection gun 14 onto the liquid material inlet 5 through the threaded fixing sleeve 13. At the same time, the liquid material injection gun 14 can block the upper end of the liquid material inlet 5. In the initial state, the first return spring 17 pulls the limiting block 16 to stop at the upper end of the limiting groove 15. The elastic dispersion plate 21 is housed inside the mounting plate 20 under the force of the pull rope 19. At this time, the second return spring 22 is in a compressed state. When the threaded fixing sleeve 13 is screwed in, the threaded fixing sleeve 13 gradually presses down against the limiting block 16. At this time, the limiting block 16 moves down along the limiting groove 15. When it moves down, the elastically set dispersion plate 21 is gradually no longer pulled by the pull rope 19. Through the force of the second return spring 22, the dispersion plate 21 pops out to the lower end of the liquid material inlet 5 to disperse the liquid reaction material discharged from the liquid material injection gun 14.
