Description

Technical Field

[0001] The utility model relates to the technical field of manganese carbonate preparation, in particular to a PH regulating device for manganese carbonate preparation. Background Art

[0002] Manganese carbonate, or manganous carbonate, is an inorganic compound, a carbonate of divalent manganese, with the chemical formula MnCO3. It is soluble in dilute acid, insoluble in water and ethanol. Manganese carbonate is a raw material for manufacturing soft ferrites for telecommunication equipment, synthesizing manganese dioxide and manufacturing other manganese salts. It is used as a catalyst for desulfurization, a pigment for enamels, coatings and varnishes. It is also used as a fertilizer and feed additive. It is used in medicine, welding rod auxiliary materials, etc., and as a raw material for the production of electrolytic manganese metal. During the preparation of manganese carbonate, it is necessary to ensure that the pH value of the reaction solution is between 3-7. Too high a pH value will lead to oxidation of divalent manganese, and too low a pH value will lead to decomposition of carbonates. Both will affect the preparation of manganese carbonate, so it is necessary to adjust the pH of the reaction solution for preparing manganese carbonate.

[0003] However, the existing PH regulating device for preparing manganese carbonate needs to control the acid liquid discharge port and the alkali liquid discharge port respectively through two electromagnetic valves, resulting in high cost of the PH regulating device, which is not conducive to popularization and use, and the PH value meter cannot be adjusted according to the height of the reaction liquid inside the reactor for preparing manganese carbonate, resulting in that when the content of the reaction liquid inside the reactor is reduced, the PH value meter cannot measure the PH of the reaction liquid, affecting the regulation of the PH of the reaction liquid. In view of the above problems, it is urgently necessary to carry out innovative design based on the original PH regulating device for preparing manganese carbonate. Utility Model Content

The rotating motor 18 drives the first stirring rod 19 and the second stirring rod 20 to rotate through the stirring shaft 17, so that the various raw materials for preparing manganese carbonate can be mixed together;

[0036] Then, the bolt 14 is rotated. Since the bolt 14 and the movable sleeve 12 are threadedly connected, the bolt 14 is separated from the guide rod 13. Then, the movable sleeve 12 and the pH meter 11 are moved downward. The height of the reaction liquid inside the reactor 1 is observed through the transparent glass 16. The bottom of the pH meter 11 is inserted into the reaction liquid. Then, the bolt 14 is rotated in the opposite direction so that the end of the bolt 14 is tightly fitted with the outer wall of the guide rod 13, so that the pH meter 11 is fixed.

[0037] When the pH meter 11 detects that the pH value of the reaction liquid is lower than 3, the pH meter 11 transmits a signal to the controller 27, and the controller 27 controls the servo motor 10 to rotate forward, and then the servo motor 10 drives the baffle 8 and the connecting hole 28 to rotate forward, so that the connecting hole 28 coincides with the alkali liquid discharge port 6, so that the alkali liquid inside the alkali liquid storage chamber 4 enters the reaction liquid inside the reactor 1 through the alkali liquid discharge port 6, so that the pH of the reaction liquid increases, until the pH value of the reaction liquid is between 3-7, the pH meter 11 transmits a signal to the controller 27, and the controller 27 controls the servo motor 10 to reverse 90 degrees, so that the connecting hole 28 is reset, and the baffle 8 closes the alkali liquid discharge port 6;

[0038] When the pH meter 11 detects that the pH value of the reaction liquid is higher than 7, the pH meter 11 transmits a signal to the controller 27, and the controller 27 controls the servo motor 10 to reverse, and then the servo motor 10 drives the baffle 8 and the connecting hole 28 to reverse, so that the connecting hole 28 coincides with the acid liquid discharge port 5, so that the acid liquid inside the acid liquid storage chamber 3 enters the reaction liquid inside the reactor 1 through the acid liquid discharge port 5, so that the pH of the reaction liquid is reduced. Until the pH value of the reaction liquid is between 3-7, the pH meter 11 transmits a signal to the controller 27, and the controller 27 controls the servo motor 10 to rotate forward 90 degrees, so that the connecting hole 28 is reset, and the baffle 8 closes the acid liquid discharge port 5.
