On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0026] This embodiment provides an acid-base neutralization device, which is more conducive to achieving a comprehensive scraping effect on the inner wall of the shell during use. Specifically, Figure 1-6As shown, it includes a reactor shell 1, an acid solution feed port 2, an alkali solution feed port 3, a discharge port 4, a stirring unit 5, a scraping and brushing member 8 and two electric push rods 9. The bottom surface of the reactor shell 1 is provided with an inorganic salt discharge port 6, and the discharge port 4 is arranged on the surface of the inorganic salt discharge port 6 and is interconnected. The bottom of the reactor shell 1 is a conical design, and the inner wall of the reactor shell 1 is set as a smooth surface, which is more conducive to the inorganic salt particles after scraping and brushing to be discharged outward through the inorganic salt discharge port 6 to avoid remaining at the bottom of the inner wall of the reactor shell 1. The surface of the reactor shell 1 is provided with a mounting frame 7, and the stirring unit 5 includes a motor 51, a connecting rod 52 and a stirring blade 53. The surfaces of the connecting rod 52 and the stirring blade 53 are respectively provided with an empty groove 1 521 and an empty groove 2 531, and the empty groove 1 521 The scraper 8 is vertically opened on the surface of the connecting rod 52, and includes a scraper 1 81 and two scraper 2 82 arranged on the bottom surface of the scraper 1 81. The scraper 1 81 is sleeved on the outer side of the connecting rod 52, and the inner side of the scraper 1 81 is provided with a protrusion 810 protruding into the empty groove 1 521, and the top surface of the scraper 1 81 is provided with a rotating groove 811. The shape and structure of the scraper 2 82 are adapted to the bottom surface shape of the reactor shell 1. Two electric push rods 9 are both arranged on the surface of the mounting frame 7, and the output end of the electric push rod 9 is provided with a slider 91 protruding into the rotating groove 811, so that the scraper 8 can move in the reactor shell 1 under the action of the electric push rod 9 and the stirring unit 5, so as to achieve a comprehensive scraping effect on the inner wall of the reactor shell 1. The scraping process is simple and convenient, and the overall practicality is stronger.

[0027] like Figure 1-2 As shown, in this embodiment, a plurality of convex plates 812 are provided on the bottom surface of the scraper 81, and the convex plates 812 are adapted to the shape and structure of the stirring blade 53. The plurality of convex plates 812 are respectively located on the front and back sides of the stirring blade 53 and at an upper position, which can effectively scrape the surface of the stirring blade 53 and prevent some inorganic salts from agglomerating and remaining on the surface of the stirring blade 53.

[0028] like Figure 1-4 As shown, in this embodiment, two spring telescopic rods 10 are provided on the surface of the mounting frame 7, and the output ends of the spring telescopic rods 10 protrude into the reactor shell 1, and the output ends of the spring telescopic rods 10 are in contact with the surface of the scraper 81, and the output ends of the spring telescopic rods 10 are in a compressed state. The top surface of the scraper 81 is provided with two protrusions 813, and the protrusions 813 are semi-cylindrical in design. The output end of the spring telescopic rod 10 is semi-circular in design. The surfaces of the protrusions 813 and the spring telescopic rod 10 are both set as smooth surfaces, so that the scraping brush member 8 can be rotated by the drive of the motor 51. As the scraping brush member 8 rotates, the two protrusions 813 have a squeezing effect on the spring telescopic rod 10, thereby utilizing the rebound of the spring telescopic rod 10 to knock the scraping brush member 8, causing it to vibrate, thereby achieving a cleaning treatment of some inorganic salt particles that may be attached to and remain on the surface of the scraping brush member 8.

[0029] like Figure 1-5 As shown, in this embodiment, two plastic plates 11 are provided on the surface of the mounting frame 7, and a baffle 12 is provided on the surface of the plastic plate 11. The surfaces of the two baffles 12 are close to each other and are located on the outside of the connecting rod 52. The two baffles 12 are located between the mounting frame 7 and the top surface of the reactor shell 1. The plastic plate 11 is designed in a "J" shape. Two anti-slip rubber pads 13 are provided on the inner side of the plastic plate 11. The two anti-slip rubber pads 13 are in close contact with the surface of the mounting frame 7. A handle 14 is provided on the surface of the plastic plate 11, so that the staff can use the handle 14 to move the plastic plate 11 and the baffle 12 between the mounting frame 7 and the top surface of the reactor shell 1 to achieve a shielding and protective effect on the connecting rod 52, thereby preventing foreign debris from falling and being connected to the empty slot 521 opened by the connecting rod 52 and affecting use.

[0030] During the use of the above-mentioned acid-base neutralization device, if it is necessary to clean the inner wall of the reactor shell 1, the staff opens the inorganic salt discharge port 6 and starts the electric push rod 9, and uses the electric push rod 9 to drive the scraper 8 to move downward in the reactor shell 1. During the movement, the scraping and brushing effect on the inner wall can be achieved until the bottom surface of the scraper 2 82 coincides with the bottom surface of the inner wall of the reactor shell 1, and then the motor 51 of the stirring unit 5 is started. The motor 51 drives the connecting rod 52 and the stirring blade 53 to rotate simultaneously, and the scraper 1 81 sleeved on the outside of the connecting rod 52 drives the scraper 2 82 to rotate simultaneously by the protrusion 810 located in the empty groove 1 521, so that the scraper 2 82 can achieve the scraping and brushing effect on the bottom surface of the inner wall of the reactor shell 1, and the inorganic salt particles scraped and dropped by the scraper 2 82 fall downward, slide down and roll on the inclined surface of the bottom surface of the reactor shell 1, and are discharged outward through the inorganic salt discharge port 6.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
