[0019] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0020] Embodiment 1, a dosing device for lithium carbonate production, comprising a mixing box 1, characterized in that: The mixing box 1 is provided with a liquid inlet pipe 2 at the top and a liquid outlet pipe 3 at the bottom, and both the liquid inlet pipe 2 and the liquid outlet pipe 3 are provided with a first valve; The mixing box 1 is provided with a medicine feeding pipeline 4, a medicine feeding hopper 5 and a carrying box 6. The medicine feeding hopper 5 is located above the medicine feeding pipeline 4. The medicine feeding pipeline 4 is fixedly connected with the carrying box 6. A retractable pipeline 7 is provided between the carrying box 6 and the medicine feeding hopper 5. The mixing box 1 is provided with a sliding groove 8. The medicine feeding pipeline 4 and the sliding groove 8 are slidably matched. Two groups of fixed plates 9 are fixedly connected to the mixing box 1. The two groups of fixed plates 9 are fixedly connected to the medicine feeding hopper 5. The medicine feeding pipeline 4 and the medicine feeding hopper 5 are provided with a second valve 10. The mixing box 1 is fixedly connected with two groups of gravity sensors 11 that cooperate with the carrying box 6 .

[0021] As an optional solution of Example 1, a stirring paddle 12 is rotatably connected in the mixing box 1, a motor 13 is provided at the bottom of the mixing box 1, the stirring paddle 12 is driven by the motor 13, and the motor 13 is electrically connected to the controller.

[0022] As an optional solution of Example 1, the carrying box 6 is provided with a drainage hopper 18, which is conical in shape and has openings at the top and bottom, wherein the end with a larger opening corresponds to the retractable pipe 7, and the end with a smaller opening corresponds to the drug feed pipe 4.

[0023] As an optional solution of Example 1, a shock-absorbing base 19 is provided at the bottom of the mixing box 1.

[0024] As an optional solution of Embodiment 1, a sampling pipe 14 is provided on the side wall of the mixing box 1, and a third valve is provided on the sampling pipe 14.

[0025] When in use, lime is put into the medicine feeding hopper 5, and the amount of lime powder fed is controlled by driving the second valve 10, which can be a solenoid valve or a handle valve. The lime powder passes through the discharge pipe of the medicine feeding hopper 5 and the retractable pipe 7, and finally enters the carrying box 6. The second valve 10 arranged on the medicine feeding pipe 4 is in a closed state at this time, and the lime powder entering the carrying box 6 becomes heavier and heavier, and the carrying box 6 descends under the action of gravity. Since the mixing box 1 is provided with a gravity sensor 11, wherein the gravity sensor 11 is used in conjunction with the carrying box 6, the weight of the lime powder inside the carrying box 6 can be detected under the action of the gravity sensor 11, and the weight of the lime powder can be accurately controlled through control; As the weight of the carrying box 6 increases, the medicine feeding pipe 4 is inserted deeper into the mixing box 1 along the sliding groove 8; The mixing box 1 is filled with lithium carbonate mother liquor, and the acidic solution is introduced into the mixing box 1 through the liquid inlet pipe 2. The motor 13 is driven to drive the stirring paddle 12 to rotate. After the mixing is completed, the sample is taken through the sampling pipe 14 to detect the pH value of the mixed solution and obtain the required amount of lime; The amount of lime powder added to the carrying box 6 is determined by controlling the second valve 10 provided on the medicine feeding hopper 5. Under the action of the gravity sensor 11, the weight of the carrying box 6, that is, the weight of the lime powder, can be observed in real time. The gravity sensor 11 cooperates with the controller, and the weight is displayed on the display screen, which is convenient for the operator to observe. Finally, the lime powder in the carrying box 6 is introduced into the mixing box 1 by driving the second valve 10 provided on the drug inlet pipe 4, and the motor 13 is continuously driven to rotate the stirring paddle 12 to stir the internal liquid evenly, and then sampling and testing are performed through the sampling pipe 14 to ensure that the internal pH value reaches the production index.
