Referring to fig. 2, a first sensor 112 is disposed at the lowest liquid level of the seal bin 200 for detecting whether the liquid level of the liquid to be discharged in the seal bin 200 reaches the lowest liquid level, a second sensor 114 is disposed at the liquid discharge liquid level of the seal bin 200 for detecting whether the liquid level of the liquid to be discharged in the seal bin 200 reaches the liquid discharge liquid level, and a third sensor is disposed at the highest liquid level of the seal bin 200 for detecting whether the liquid level of the liquid to be discharged in the seal bin 200 reaches the highest liquid level. Wherein, the heights of the lowest liquid level, the liquid discharge level and the highest liquid level are increased in sequence. The controller 120 is connected to the first sensor 112, the second sensor 114 and the third sensor 116 to receive the detection results of the first sensor 112, the second sensor 114 and the third sensor 116, so as to determine the liquid level of the liquid to be discharged in the seal bin. In other embodiments, other liquid levels and sensors can be arranged to realize more precise judgment of the liquid level of the liquid to be discharged.
The controller 120 is also connected to a drain 130. The controller 120 controls the drain 130 to drain based on the detection signals of the first sensor 112 and the second sensor 114. In this embodiment, the controller 120 controls the draining device 130 to drain the liquid after the liquid level of the liquid to be drained reaches the draining liquid level until the liquid level of the liquid to be drained reaches the lowest liquid level, and controls the draining device 130 to stop draining the liquid after a preset time delay.
Specifically, when the second sensor 114 detects that the liquid level of the liquid to be drained reaches the drainage liquid level, the second sensor 114 outputs the detection result to the controller 120, which is equivalent to an instruction for the controller 120 to start drainage, so that the controller 120 controls the drainage device 130 to start drainage until the liquid level reaches the minimum liquid level, the first sensor 112 feeds back the detection result to the controller 120, which is equivalent to an instruction for stopping the controller 120 from draining, and after delaying for 5 seconds to 10 seconds, the controller 120 controls the drainage device 130 to stop drainage. The size of the preset time can be set according to the size of the sealed bin, the height of the lowest liquid level, the liquid discharge rate of the liquid discharge device and the like, so that the size of the liquid discharge amount is ensured to discharge the liquid to be discharged of the container as far as possible, and the liquid discharge device 130 is prevented from still discharging the liquid after the liquid to be discharged is discharged. In other embodiments, the controller 120 controls the draining device 130 to stop draining when the liquid level of the liquid to be drained reaches the minimum liquid level.
In this embodiment, the controller 120 is further configured to control the drain to stop after the third sensor 116 detects that the liquid level of the liquid to be drained in the sealed bin reaches the maximum liquid level, i.e., the maximum liquid level is also the stop water level.
