[0029] Working principle:

[0030] Auxiliary operations for neutralization of calcium nitrate:

[0031] The heating block 14 is started, and the heating block 14 heats the interior of the box body 1 to accelerate the neutralization reaction of calcium nitrate. The operator pours calcium carbonate and dilute nitric acid into the interior of the box body 1 through the first feeding pipe 7 and the second feeding pipe 8, respectively, and connects the external power supply of the second motor 501, starts the second motor 501, and the output shaft of the second motor 501 rotates to drive the stirring rod 502 to rotate (as shown in FIG. Figure 3 ), the rotation of the stirring rod 502 breaks the material stratification, increases the contact opportunity of the reactants, and improves the neutralization speed of the materials. The rotation of the stirring rod 502 drives the first bevel gear 503 to rotate, and the rotation of the first bevel gear 503 drives the second bevel gear 504 to rotate. The rotation of the second bevel gear 504 drives the third bevel gear 505 to rotate. The rotation of the third bevel gear 505 drives the cylinder 506 to rotate.

The scraper 507 rotates and keeps scraping against the inner wall of the box body 1 to reduce the residual material on the inner wall, so that the box body 1 maintains good heat transfer performance.

[0032] When the second motor 501 is started, the first motor 301 is started at the same time. The output shaft of the first motor 301 rotates to drive the connecting rod 302 to rotate. The connecting rod 302 rotates to drive the slider 303 to slide upward in the second housing 304. Figure 5 ) At the same time, the second shell 304 moves to the right, and the movement of the second shell 304 drives the convex plate 306 to slide to the right on the sliding rod 307. The movement of the convex plate 306 drives the box body 6 to move. It is further understood that the convex plate 306 is stably fixed to the box body 6 by bolts. When the connecting rod 304 is in a vertical state, the continued rotation of the connecting rod 304 causes the spring 305 to rebound, thereby quickly moving to the right, thereby driving the box body 6 to move quickly to the right. When the box body 6 moves to the right limit position, the output shaft of the first motor 301 is reversed. The first motor 301 causes the box body 6 to move quickly to the left in the above manner, thereby causing the box body 6 to reciprocate rapidly, which can strongly disturb the materials in the box body 6, so that the reactants are more fully contacted, thereby improving the neutralization reaction rate and efficiency, and accelerating the formation of calcium nitrate. It is further understood that the lower end of the concave block 12 at the lower end of the box body 6 is equipped with multiple pulleys.

Close the solenoid valve, and the work flow of the neutralization auxiliary device for calcium nitrate production is completed.
