[0018] The following is combined with Figure 1-5 The specific implementation methods of the utility model are further described in detail.

[0019] Embodiment 1, the technical solution is that when the present application is in use, the acidity detection device can drive the lifting rod 9 to move vertically through the positioning motor 8 and the screw rod 7, and then the detection rod 10 together with the acidity detection probe 4 will also be lifted and lowered in the storage tank body 1, and then the acidity of the mother liquor in the storage tank body 1 can be measured at different heights, thereby ensuring the accuracy of the acidity detection, and the acidity detection probe 4 can directly measure the result with the acidity detector 3, and the detection efficiency is high. When the acidity detected in the mother liquor is too high, a proper amount of ammonia water in the ammonia water storage tank can be sent into the storage tank body 1 through the metering pump 15 and stirred through the mixing device, thereby reducing the acidity of the mother liquor, so that the acidity of the mother liquor is stabilized in the corresponding range.

[0020] Embodiment 2, based on embodiment 1, specifically, when the present application is in use, the ammonium sulfate mother liquor can be fed into the storage tank body 1 through the liquid inlet pipe 21, the magnetic float ball level gauge 2 on the storage tank body 1 can display the liquid level in the storage tank body 1, and the mother liquor in the storage tank body 1 can be discharged from the drain pipe 22 by opening the drain valve 23.

[0021] When the acidity of the mother liquid in the storage tank body 1 is measured, in order to ensure the detection accuracy, the mother liquid can be tested at different depths by the acidity detection probe 4, and multiple sets of data can be obtained for comparative calculation to ensure the detection accuracy. Specifically, the positioning motor 8 on the support plate 6 is started to rotate forward, and the positioning motor 8 will drive the screw rod 7 to rotate forward, and the screw rod 7 will drive the lifting rod 9 to move downward along the vertical tube, and then the detection rod 10 together with the acidity detection probe 4 fixed on the detection rod 10 by the clamp 11 will also move downward synchronously; correspondingly, starting the positioning motor 8 to reverse will make the detection rod 10 move upward together with the acidity detection probe 4, and stopping the positioning motor 8 can position the acidity detection probe 4 at the corresponding height in the mother liquid, and then the acidity of the mother liquid can be measured at different depths, and the acidity detection probe 4 interacts with the mother liquid and converts it into an electrical signal to be transmitted to the acidity detector 3 for acidity display.

[0022] According to the acidity measured by the acidity detector 3, when the acidity is too high, the acidity can be reduced by the acidity balancing device, specifically, the liquid supply valve 16 is opened and the metering pump 15 is started. Under the action of the metering pump 15, the ammonia water in the ammonia water storage tank 13 will enter the storage tank body 1 through the front conduit 14 and the rear conduit 17 to mix with the mother liquor, so as to reduce the acidity of the mother liquor. Furthermore, in order to improve the mixing efficiency of ammonia water and mother liquor, the stirring motor 20 can be started, and the stirring motor 20 will drive the stirring shaft 18 and the stirring rod 19 to rotate synchronously, thereby increasing the mixing efficiency.
