[0025] 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.

[0026] like Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: A neutralization reaction vessel includes a vessel body 1, and a rotating cylinder 12 is rotatably arranged in the middle of the vessel body 1. The bottom end of the rotating cylinder 12 rotatably penetrates the bottom surface of the vessel body 1. The bottom end of the rotating cylinder 12 is open.

[0027] The top of the vessel body 1 is equipped with a rotating assembly that drives the rotating drum 12 to rotate.

[0028] The rotating assembly includes a motor 3, which is fixedly connected to the top of the vessel body 1. A rotating shaft 9 is fixedly connected to the output end of the motor 3, and the rotating shaft 9 rotates through the top surface of the vessel body 1. The bottom end of the rotating shaft 9 is coaxially fixedly connected to the top of the rotating drum 12. The motor 3 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the rotating drum 12 to rotate.

[0029] A stirring element is provided on the outer surface of the bottom of the rotating drum 12.

[0030] Several agitators are provided, and these agitators are fixedly connected to the rotating drum 12 at intervals from bottom to top. The rotating drum 12 is arranged vertically. The rotating drum 12 drives the agitators to rotate, so that the agitators mix and stir the solution in the vessel body 1.

[0031] The agitator includes a sleeve 10, which is fixedly fitted onto the rotating drum 12. Several agitator blades 5 are uniformly fixedly connected to the outer surface of the sleeve 10, and the blades 5 are inclined. This allows the agitator blades 5 to perform agitation, and the inclined arrangement enables the fluid dynamics generated during rotation to be decomposed into axial and radial components, enhancing the upward and downward circulation of the solution.

[0032] Each stirring blade 5 has several circular holes 7 spaced apart, and the circular holes 7 on the same stirring blade 5 are arranged in a straight line. When the stirring blade 5 is stirring, the circular holes 7 can disrupt the laminar boundary layer on the surface of the stirring blade 5, induce the solution to pass through the circular holes 7, thereby forming local eddies and micro-shear zones, increasing the degree of turbulence between solutions, and accelerating the dispersion and mixing process.

[0033] Each sleeve 10 has two inclined grooves 11 on its bottom surface, and the two inclined grooves 11 are arranged in a circumferential array about the sleeve 10. The top surface of each inclined groove 11 is inclined. When the sleeve 10 drives the inclined grooves 11 to rotate, the inclined grooves 11 can push the solution to move, so as to make the solution mix evenly.

[0034] A connecting frame 8 is fixedly connected to the outer surface of the top of the rotating drum 12, and the inner cavity of the connecting frame 8 communicates with the inner cavity of the rotating drum 12. A communicating hole adapted to the inner cavity of the connecting frame 8 is provided on the rotating drum 12.

[0035] The bottom surface of the inner cavity of the connecting frame 8 is inclined, gradually sloping upwards from one end near the rotating drum 12 to the other end. This inclined design facilitates the entry of materials into the rotating drum 12.

[0036] A feed inlet is provided at the end of the connecting frame 8 away from the rotating drum 12, and a spiral conveying blade 6 is fixedly connected to the feed inlet of the connecting frame 8. The conveying blade 6 has an L-shaped cross-section and slides against the inner wall of the vessel body 1. The bottom end of the conveying blade 6 slides against the bottom surface of the inner cavity of the vessel body 1. This allows the conveying blade 6 to scrape away the salt on the inner wall of the vessel body 1 when it rotates.

[0037] There is a distance between the top surface of the top sleeve 10 and the connecting frame 8, so that the solution is prevented from entering the connecting frame 8 when the solution is stirred.

[0038] A connecting ring is fixedly sleeved on the outer surface of the bottom of the rotating drum 12, and several arc-shaped scrapers 13 are evenly fixedly connected to the outer surface of the connecting ring. The bottom surface of the scraper 13 slides in contact with the bottom surface of the inner cavity of the vessel body 1. This allows the scraper 13 to scrape off the salt adhering to the inner wall of the vessel body 1 when rotating, and to transport the salt to the side wall at the bottom of the vessel body 1.

[0039] The connecting ring also slides into the bottom surface of the inner cavity of the rotating cylinder 12, and the connection between the rotating cylinder 12 and the vessel body 1 is sealed by the connecting ring.

[0040] A discharge pipe is fixedly connected to the bottom of the vessel body 1, and a valve is installed on the discharge pipe. A first feed pipe 2 and a second feed pipe 4 are fixedly connected to the top of the vessel body 1.

[0041] Working principle:

[0042] In use, the reaction solution is introduced into the vessel body 1 through the first feed pipe 2 and the second feed pipe 4 respectively. The top surface of the solution is flush with the top surface of the topmost sleeve 10.

[0043] Start motor 3, which drives shaft 9 to rotate. Shaft 9 drives drum 12 to rotate, which in turn drives sleeve 10 and stirring blades 5 to rotate, stirring the solution and allowing it to mix and undergo a neutralization reaction. Simultaneously, it drives scraper 13, conveying blades 6, and connecting frame 8 to rotate.

[0044] The stirring blades 5 are angled, allowing the hydrodynamic force generated during rotation to be decomposed into axial and radial components, enhancing the vertical circulation of the solution. The circular holes 7 disrupt the laminar boundary layer on the surface of the stirring blades 5, inducing the solution to pass through the holes 7, thereby forming local eddies and micro-shear zones, increasing the turbulence between solutions, and accelerating the dispersion and mixing process. The inclined grooves 11 can propel the solution to facilitate uniform mixing.

[0045] The neutralization reaction produces salt. The scraper 13 scrapes the salt off the bottom surface of the vessel 1 and pushes the salt to the inner wall of the vessel 1.

[0046] The conveying blades 6 transport the salt from the bottom surface of the vessel body 1 upwards. The salt then enters the connecting frame 8, slides into the rotating drum 12, and is discharged downwards through the bottom of the rotating drum 12. This process removes some of the salt from the vessel body 1, reducing the likelihood of clogging the discharge port.

[0047] After the reaction is complete, open the valve on the discharge pipe to discharge the neutralized product through the discharge pipe.

[0048] Although the present invention 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 invention should be included within the protection scope of the present invention.
