Description

Technical Field

[0001] The utility model relates to the field of reaction equipment, in particular to a hot water spraying and stirring device for ammoniation reaction of quaternary ammonium salt of lanolinic acid. Background Art

[0002] In the ammoniumization reaction of quaternary ammonium salts of lanolate, ensuring efficient mixing of reactants and precise temperature control are key factors in improving reaction efficiency and optimizing product quality. Traditionally, this process relies on the synergistic effect of a stirring device within the reactor and a hot water spray system overhead. While this combination facilitates reactant mixing and heating to a certain extent, it still faces numerous challenges in practical application.

[0003] Specifically, when hot water is injected directly into the mixed liquid in the reactor via a spray device, the density of water is generally lower than that of the reactants. Furthermore, due to the physical properties of hot solutions naturally rising and cold solutions naturally sinking, the hot water has difficulty quickly and evenly penetrating all layers of the reactants, thus limiting heating efficiency. Furthermore, this uneven heating pattern can cause localized overheating or overcooling, affecting the uniformity of the reactant mixing and, in turn, the reaction speed and effectiveness between the reactants.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1:

[0021] refer to Figure 1 A hot water spray stirring device for ammoniumization reaction of quaternary ammonium salt of lanolinic acid comprises a reactor 1, which is a reaction vessel and is provided with a stirring device 2 and a spraying device 3.

[0022] The stirring device 2 includes a stirring motor 21, which is fixed to the top of the reactor 1. A stirring rod 22 is provided on the output shaft of the stirring motor 21, and the stirring rod 22 extends into the reactor 1. A stirring paddle 23 is provided at the bottom of the stirring rod 22. The stirring paddle 23 is driven by the stirring motor 21 to rotate, which drives the rotation of the reactants in the reactor 1, thereby improving the mixing uniformity of the reactants in the reactor 1 and improving the reaction speed and effect.

[0023] The spray device 3 includes at least one spray unit, and the spray unit includes at least one spray part. The spray part includes a fixed plate 31. The fixed plate 31 is provided on the inner wall of the reactor 1 and can be fixed by welding or by a bolt assembly. The fixed plate 31 can be embedded in the inner wall of the reactor 1 to prevent the fixed plate 31 from protruding and affecting the flow of the reactants in the reactor 1; the bottom of the fixed plate 31 can be flush with the stirring paddle 23, and a plurality of spray nozzles 32 are provided on the fixed plate 31. The spray nozzles 32 can be circular tubes. The spray nozzles 32 are connected to a hot water delivery device, and the hot water delivery device sprays hot water into the reactants in the reactor 1 through the spray nozzles 32.

[0024] Specifically, the stirring paddle 23 rotates, driving the reactants to rotate in the reactor 1, forming a rotating vortex of the reactants, and hot water is sprayed out from the spray nozzle 32 and flows into the vortex of the reactants. Since the temperature of the hot water is lower than the temperature of the reactants and the density of the hot water is smaller than the density of the reactants, the hot water has a tendency to flow upward. At the same time, the vortex drives the hot water to rotate, so that after the hot water enters the vortex of the reactants, it diffuses in multiple directions along the vortex trajectory, thereby accelerating the uniform mixing of the hot water and the reactants, and then increasing the heating speed of the reactants by the hot water. After the reactants are heated, their activity is enhanced, which accelerates the mixing between the reactants, thereby achieving efficient mixing and uniform heating of the reactants, promoting sufficient contact and reaction between the reactants, and improving the reaction efficiency and product quality.

[0025] In some embodiments, at least four partition plates 11 are provided on the inner wall of the reactor 1. The four partition plates 11 are distributed in a ring shape on the inner wall of the reactor 1, and can form multiple interconnected spaced areas in the reactor 1, thereby guiding the flow of reactants and improving mixing efficiency.

[0026] In some embodiments, the cross-section of the separator 11 is a right-angled trapezoid, and the inclined surface of the separator 11 faces away from the rotation direction of the stirring paddle 23, that is, the vortex formed by the reactants driven by the stirring paddle 23 collides with the inclined surface of the separator 11, causing the reactants to flow toward the middle along the inclined surface, thereby promoting the circulation of the reactants during the stirring process.

[0027] In some embodiments, the bottom of the separator 11 is flush with the center axis of the stirring paddle 23 , so that the reactants in the reactor 1 form two different flow spaces at the stirring paddle 23 , further promoting the circulation of the reactants during the stirring process.

[0028] In some embodiments, there are two spray members, which are located in the liquid of the reactor 1 and are staggered in height to achieve a wider spray coverage area of ​​the spray nozzle 32 in the reactants, thereby improving the heating uniformity of the reactants.

[0029] The specific working principle is as follows:

[0030] During operation, the stirring motor 21 rotates the stirring rod 22 and the stirring paddle 23, stirring and mixing the reactants in the reactor 1. Simultaneously, the hot water delivery device delivers hot water to the spray nozzle 32, where it is evenly sprayed onto the surface of the reactants, heating them. This dual action of stirring and spraying achieves efficient mixing and uniform heating of the reactants, improving the efficiency of the ammonium salt ammoniumization reaction and product quality.

[0031] Example 2:

[0032] refer to Figure 2-3 This embodiment is different from the embodiment in the structure of the spray nozzle 32.

[0033] Specifically, a check member 4 is provided in the spray nozzle 32 to prevent the reactants from flowing back into the spray nozzle 32 .

[0034] The check member 4 includes a diverter plate 41, which is fixed in the spray nozzle 32. A fixed shaft 42 is provided in the spray nozzle 32. The fixed shaft 42 is provided on the side of the spray nozzle 32 close to the stirring paddle 23 and is arranged parallel to the diverter plate 41. Two semicircular plates 43 are sleeved on the fixed shaft 42. The semicircular plates 43 can rotate on the fixed shaft 42. The two semicircular plates 43 are symmetrically arranged and can block the spray nozzle 32. A torsion spring 44 is provided between the semicircular plate 43 and the fixed shaft 42 to realize the automatic opening and closing function and prevent the reactants from backflowing.

[0035] Specifically, when hot water is being transported, the hot water will impact the semicircular plate 43, and the semicircular plate 43 will rotate to a horizontal state, causing the torsion spring 44 to elastically deform, opening the spray nozzle 32, and hot water will flow out of the spray nozzle 32. When the hot water is stopped, the torsion spring 44 will restore the elastic deformation, and the semicircular plate 43 will rotate to a vertical state following the torsion spring 44. The two semicircular plates 43 will jointly block the spray nozzle 32. At the same time, the liquid in the reactor 1 will flow toward the spray nozzle 32, applying a force to the semicircular plate 43 to enhance the blocking performance of the semicircular plate 43.

[0036] In some embodiments, the non-return member 4 also includes an auxiliary ring 45, which is coaxially arranged on the side of the spray nozzle 32 close to the stirring paddle 23. A diverter plate 41 is fixed to the middle of the auxiliary ring 45. The auxiliary ring 45 fits with the semicircular plate 43 to prevent the semicircular plate 43 from rotating toward the side away from the stirring paddle 23 under the action of the liquid in the reactor 1, thereby causing the semicircular plate 43 to fail to seal the spray nozzle 32, thereby ensuring the non-return effect.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
