The present application provides a chemical compounding system that includes a plurality of compounding units 100 that are capable of independently compounding. Each dosing unit 100 includes a compounding tank 110, a concentration meter 130, and a circulation pump 120. The feed inlet and the discharge outlet of the circulation pump 120 are both communicated with the mixing tank 110 to form a circulation pipeline, and the solution in the mixing tank 110 enters the circulation pipeline under the action of the circulation pump 120 and returns to the mixing tank 110 from the circulation pipeline. The concentration meter 130 is provided to the circulation line so that the concentration of the solute in the solution can be measured by the concentration meter 130 during the passage of the solution through the circulation line.

Further, the mixing tank 110 includes a discharge port and a return port, the discharge port of the mixing tank 110 is provided with a second valve 111, and the return port of the mixing tank 110 is provided with a third valve 112. The feed inlet of the circulation pump 120 is communicated with the discharge outlet of the mixing tank 110 through a first pipeline 141, and the discharge outlet of the circulation pump 120 is communicated with the feed back outlet of the mixing tank 110 through a second pipeline 142, wherein the pipeline formed by the first pipeline 141, the second pipeline 142 and the circulation pump 120 is a circulation pipeline.

Under the condition that the second valve 111 and the third valve 112 are both opened, the solution in the mixing tank 110 can enter a circulation pipeline from the second valve 111 under the action of the circulation pump 120, and then returns to the mixing tank 110 from the third valve 112, so that the solution can be mixed in the process, the solute can be uniformly distributed, and whether the concentration of the solute in the solution reaches the requirement can be detected through the concentration meter 130 in the circulation process.

In some preferred embodiments of the present application, the circulation line between each dosing unit 100 is also in communication through a first valve 150 that can be opened and closed. With the first valve 150 open, the solution may move from the first valve 150 to the other circulation line during movement along the circulation line in one of the dosing units 100 due to the circulation pump 120, and the concentration of the solute in the solution may be measured by the concentration meter 130 in the other circulation line. In the chemical mixing system provided in the above embodiment, since the two mixing units 100 are further communicated through the first valve 150, in the case that the concentration meter 130 in one mixing unit 100 fails, the concentration meter 130 in the other mixing unit 100 can be used for detection, without waiting for the concentration meter 130 to fail and then mixing, or transferring the solution in the mixing tank 110 to the other mixing unit 100 as a whole for mixing, so that the influence of the concentration meter 130 failure on the mixing efficiency is reduced, and the mixing efficiency is ensured.

That is, the chemical compounding system provided in the above embodiment of the present application can not only achieve the simultaneous use of a plurality of the compounding units 100 for compounding to improve the compounding efficiency, but also avoid affecting the compounding efficiency due to the malfunction of the concentration meter 130. It should be understood by those skilled in the art that a plurality of feed inlets are also provided on the compounding tank 110, and different kinds of materials are added into the tank body through the feed inlets on the compounding tank to carry out compounding.

When the operator detects the concentration of the solute in the solution in the second dosing unit using the concentration meter 130 in the first dosing unit, the second valve 111 and the third valve 112 in the first dosing unit may be closed to prevent the solution in the first dosing unit from entering the dosing tank 110 in the second dosing unit.

When the compounding tanks 110 provided in the present application are used to prepare solutions with a large demand, the solute and the target concentration of the solutions prepared in each compounding tank 110 are the same, and thus the concentration meters 130 in different compounding units 100 can be used with each other.

In this application, the number relationship between the supply pump 170 and the feed port is not particularly limited, and in other embodiments, one supply pump 170 may be disposed corresponding to the mixing tank 110 in each mixing unit 100.
