Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to an additive reaction vessel with an anti-crystallization stirring structure. Background Technology

[0002] In the production of additives in a reaction vessel, the stirring and temperature control functions of this closed container are used to allow various raw materials to be transformed into auxiliary chemicals with specific properties through chemical reactions or physical mixing. The materials are uniformly mixed by a stirrer, and then the temperature, pressure and other conditions are controlled by a jacket or coil to promote the polymerization, condensation and other reactions of the raw materials. When producing additives in a reactor, due to differences in the viscosity of the materials, insufficient stirring can cause slow material flow within the reactor, making it impossible to evenly disperse the solute in a timely manner. This can lead to a gradual increase in the solute concentration in localized areas, exceeding the solvent's dissolving capacity. Simultaneously, exothermic reactions or uneven cooling can cause localized temperature deviations. For example, if the temperature near the cooling jacket is low, the solute solubility decreases, resulting in solute molecules in supersaturated areas accumulating along the crystal nucleus and forming crystals. Utility Model Content

[0003] The purpose of this invention is to provide an additive reaction vessel with an anti-crystallization stirring structure, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An auxiliary agent reaction vessel with an anti-crystallization stirring structure includes a reaction vessel body, multiple support legs fixedly installed at the bottom of the reaction vessel body, a top cover fixedly installed at the top of the reaction vessel body, and multiple feed inlets fixedly installed at the top of the reaction vessel body, arranged circumferentially along the top cover. A base is fixedly installed at the top of the reaction vessel body near the top cover, and a motor is fixedly installed at the top of the base. A first stirring shaft is fixedly installed at the output end of the motor. One end of the first stirring shaft extends into the reaction vessel body and a second stirring shaft is fixedly installed thereon. The motor is electrically connected to an external main controller via a cable. A discharge pipe is fixedly installed at the bottom of the reaction vessel body. A guide ring is fixedly installed inside the reaction vessel body. A stirring mechanism is movably installed outside the second stirring shaft. The stirring mechanism also includes a central shaft. Stirring blades are fixedly installed outside the central shaft. Multiple clamping blocks are fixedly installed at the top and bottom of the central shaft. Multiple supporting shafts are also fixedly installed outside the stirring mechanism.

[0005] As a further preferred embodiment of this utility model, the guide ring has a ring-shaped wave structure. Setting the guide ring into a wave structure can provide a basis for the vertical reciprocating lifting and lowering of the stirring mechanism.

[0006] As a further preferred embodiment of this utility model, a connecting block is fixedly installed on the top of the second stirring shaft, and the connecting block is fixedly installed on the bottom of the first stirring shaft. The second stirring shaft and the connecting block are connected by bolts, and the connecting block and the first stirring shaft are also connected by bolts, which facilitates the assembly of the second stirring shaft and the stirring mechanism as well as subsequent maintenance.

[0007] As a further preferred embodiment of this utility model, the top and bottom of the central shaft are fixedly installed with bosses, and the central shaft is inserted into the second stirring shaft. The central shaft is inserted into the second stirring shaft with a rectangular cross section, which enables the central shaft to move vertically and radially on the second stirring shaft.

[0008] As a further preferred embodiment of this utility model, the two clamping blocks are grouped together and have a columnar structure. The bottom of the clamping block has an installation groove, and the top of the installation groove has a shaft hole. Two ball grooves are also provided on the outside of the clamping block. Balls are rotatably installed in the ball grooves. The two clamping blocks are fixedly installed on the boss at the top of the central shaft by screws. The ball in the ball grooves abuts against the outside of the second stirring shaft.

[0009] As a further preferred embodiment of this utility model, multiple L-shaped base plates are fixedly installed on the top of the clamping block. The L-shaped base plates are located above the ball groove, and a top rod is fixedly installed on one end of the L-shaped base plate. The end of the top rod away from the L-shaped base plate has a spherical groove and abuts against the outside of the ball. The clamping blocks are installed in pairs on the top or bottom of the central shaft, and the ball in the ball groove abuts against the outside of the second stirring shaft. This can reduce the frictional force of the central shaft moving vertically and radially on the second stirring shaft. In addition, the setting of the top rod can ensure the rotational stability of the ball in the ball groove, while allowing the material entering the ball groove to flow out, reducing material residue.

[0010] As a further preferred embodiment of this utility model, a rotating shaft is fixedly installed at the end of the supporting shaft away from the stirring blade, and a roller is fixedly installed on the outside of the rotating shaft. The outside of the roller is tumblingly connected to the guide ring. The stirring blade, together with the holding block, the supporting shaft and the roller, can reciprocate vertically when moving axially inside the reactor, thereby increasing the turbulence of the material inside the reactor and reducing the probability of material crystallization.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a second stirring shaft with a rectangular cross-section is provided at one end of the first stirring shaft, and a central shaft is inserted and installed on the outside of the second stirring shaft. A stirring blade is provided on the outside of the central shaft, and a support shaft is provided on the outside of the stirring blade. Two retaining blocks are also provided at the top and bottom of the central shaft, and ball bearings are provided inside the retaining blocks. Thus, with the cooperation of the guide ring inside the reactor body, the stirring blade can move axially and reciprocate vertically at the same time. The increased stirring turbulence can make the material mix more evenly, avoid local oversaturation, and destroy the formation of crystal nuclei, making it difficult for the solute to aggregate, thereby reducing the probability of crystallization.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1-5As shown, the present invention provides an auxiliary agent reaction vessel with an anti-crystallization stirring structure, comprising a reaction vessel body 1, multiple support legs 2 fixedly installed at the bottom of the reaction vessel body 1, a top cover 3 fixedly installed at the top of the reaction vessel body 1, multiple feed inlets 4 fixedly installed at the top of the reaction vessel body 1, and the multiple feed inlets 4 arranged circumferentially along the top cover 3, a base 5 fixedly installed at the top of the reaction vessel body 1 near the top cover 3, a motor 6 fixedly installed at the top of the base 5, and a first stirring shaft 7 fixedly installed at the output end of the motor 6, one end of the first stirring shaft 7 extending... A second stirring shaft 10 is fixedly installed inside the reactor body 1, and a motor 6 is electrically connected to an external main controller via a cable. A discharge pipe 8 is fixedly installed at the bottom of the reactor body 1, and a guide ring 9 is fixedly installed inside the reactor body 1. A stirring mechanism 11 is movably installed on the outside of the second stirring shaft 10. The stirring mechanism 11 also includes a central shaft 12. A stirring blade 13 is fixedly installed on the outside of the central shaft 12. Multiple clamping blocks 14 are fixedly installed at the top and bottom of the central shaft 12. Multiple supporting shafts 15 are also fixedly installed on the outside of the stirring mechanism 11.

[0016] like Figure 2 As shown, the guide ring 9 has a ring-shaped wave structure. Setting the guide ring 9 into a wave structure can provide a basis for the vertical reciprocating lifting and lowering of the stirring mechanism 11.

[0017] like Figure 3 As shown, a connecting block 16 is fixedly installed on the top of the second stirring shaft 10, and the connecting block 16 is fixedly installed on the bottom of the first stirring shaft 7. The second stirring shaft 10 and the connecting block 16 are connected by bolts, and the connecting block 16 and the first stirring shaft 7 are also connected by bolts, which facilitates the assembly of the second stirring shaft 10 and the stirring mechanism 11 and subsequent maintenance. The top and bottom of the central shaft 12 are both fixedly installed with bosses, and the central shaft 12 is inserted into the second stirring shaft 10. The central shaft 12 is inserted into the second stirring shaft 10 with a rectangular cross section, which allows the central shaft 12 to move vertically and radially on the second stirring shaft 10.

[0018] like Figures 3-5As shown, the clamping blocks 14 are arranged in pairs and have a columnar structure. A mounting groove 17 is provided at the bottom of each clamping block 14, and a shaft hole 18 is provided at the top of the mounting groove 17. Two ball grooves 19 are also provided on the outer side of each clamping block 14, with balls rotatably mounted within them. The two clamping blocks 14 are fixedly mounted on the boss at the top of the central shaft 12 by screws. The balls in the ball grooves 19 abut against the outer side of the second stirring shaft 10. Multiple L-shaped base plates 20 are fixedly mounted on the top of each clamping block 14, positioned above the ball grooves 19. A push rod 21 is fixedly mounted on one end of each L-shaped base plate 20. The end of the push rod 21 away from the L-shaped base plate 20 has a spherical groove and abuts against the outer side of the balls. The clamping blocks 14 are then mounted in pairs on the top or bottom of the central shaft 12. The ball bearings in the ball groove 19 abut against the outside of the second stirring shaft 10, which reduces the friction of the central shaft 12 moving vertically and radially on the second stirring shaft 10. The top rod 21 ensures the stability of the ball bearing rotation in the ball groove 19 while allowing the material entering the ball groove 19 to flow out, reducing material residue. A rotating shaft 22 is fixedly installed at the end of the support shaft 15 away from the stirring blade 13. A roller 23 is fixedly installed on the outside of the rotating shaft 22. The outside of the roller 23 is rolledly connected to the guide ring 9. The stirring blade 13, together with the holding block 14, the support shaft 15 and the roller 23, can reciprocate vertically when moving axially in the reactor body 1, thereby increasing the turbulence of the material in the reactor body 1 and reducing the probability of material crystallization.

[0019] It should be noted that this utility model is an auxiliary reaction vessel with an anti-crystallization stirring structure. After the material is fed into the reaction vessel 1 through the feed port 4 at the top of the reaction vessel 1, the motor 6 can be started by an external main controller. Then, the output end of the motor 6 drives the first stirring shaft 7 to rotate through the coupling. The first stirring shaft 7 drives the second stirring shaft 10 to rotate inside the reaction vessel 1 through the connecting block 16. The central shaft 12 is inserted and installed on the second stirring shaft 10. The stirring blades 13 on the outside of the central shaft 12 rotate accordingly. At the same time, the roller 23 at the end of the support shaft 15 rolls along the wave-shaped structure of the guide ring 9, so that the stirring mechanism 11 moves vertically back and forth during axial movement. The ball bearings in the holding block 14 abut against the outside of the second stirring shaft 10, reducing the moving friction of the central shaft 12. Its top rod 21 ensures the stability of the ball bearings and prevents material residue. This compound motion enhances the turbulence of the material in the vessel, makes the material mix more evenly, avoids local oversaturation, destroys the formation of crystal nuclei, and reduces the probability of crystallization.
