The liquid additive tank 510 is positioned above the weighing tank 520, and the liquid additive tank 510 and the weighing tank 520 are connected by a connection pipe 514. The liquid additive tank 510 is used to store a liquid additive. Preferably, the volume of the liquid additive tank 510 is slightly larger than the volume of the weighing tank 520. A valve 515 is arranged on a pipeline between the liquid additive tank 510 and the weighing tank 520, and when the valve 515 is opened, the liquid in the liquid additive tank 510 can automatically flow to the weighing tank 520 under the action of gravity; the valve 515 is closed when the weight of the liquid in the weigh tank 520 reaches a set value, stopping the delivery of liquid to the weigh tank 520.
The liquid adding device further comprises a controller 560, a first liquid level switch 511 and a second liquid level switch 512, wherein the controller 560 is respectively connected with the first liquid level switch 511, the second liquid level switch 512 and the valve 515. The first level switch 511 is provided at the top of the liquid additive tank 510, and the second level switch 512 is provided at the bottom of the liquid additive tank 510. The first and second level switches 511 and 512 are preferably float switches. The top of the liquid additive tank 510 is further provided with a filling hole 516, and the filling hole 516 is connected with a liquid supply device (not shown), which may be a water pump, for example. The liquid supply device is used to replenish the liquid additive tank 510 with liquid. The controller 560 is connected to the liquid supply device, and the controller 560 is configured to control the liquid supply device to stop supplying liquid to the liquid filling hole 516 when the first liquid level switch 511 detects a liquid level change, and to start supplying liquid to the liquid filling hole 516 when the second liquid level switch 512 detects a liquid level change.
