The liquid level sensor 2 detects the liquid level in the cavity 1 and sends liquid level data to the comparator, the comparator compares the liquid level data with a preset reference value (the comparator is connected with the input module, the reference value can be set and adjusted according to the requirement through the input module), when the liquid level data is larger than the reference value (namely, the condensed water is required to be discharged), a signal is output to the driving circuit of the first electromagnetic valve 3, and the driving circuit controls the first electromagnetic valve 3 to be opened, so that the condensed water is discharged through the automatic discharge port 1-2.

In this embodiment, the second solenoid valve 4 is a solenoid valve with time control, and it is understood that the opening interval of the second solenoid valve 4 and the time length of each opening may be set, and specifically, a timer and a comparator may be set. When the second electromagnetic valve 4 is closed, the timer is triggered to start counting down, the output end of the timer is connected with the input end of the comparator, the output end of the comparator is connected with the driving circuit of the second electromagnetic valve 4, and after the time length reaches the preset value of the timer, the comparator outputs an electric signal, so that the second electromagnetic valve 4 can be set to be opened at regular time, and the forced discharge is started once every fixed time period. The second electromagnetic valve 4 may use an electromagnetic valve with an opening time control, or may further add a timer and a comparator to control the opening time (e.g. 5 s) of the second electromagnetic valve 4, which will be understood by those skilled in the art and will not be described herein. To reduce the loss of compressed air during the condensed water discharge, the opening interval and the opening duration of the second solenoid valve 4 should be reasonably set. The opening interval and the opening time length of the second electromagnetic valve 4 can be distributed according to different use scenes, the use is flexible, impurities in the system can be timely discharged, and the waste of the compressed air of the system caused by forced discharge can be reduced.

The controller 6 further includes a first input module I1 and a second input module I2, where the first input module I1 is connected to the first comparator C1 and is used to set a reference value of the first comparator C1, and the second input module I2 is connected to the second comparator C2 and is used to set a reference value of the second comparator C2. In this embodiment, the working mechanism of the first electromagnetic valve 3 is the same as that of embodiment 1, and the working is triggered according to the liquid level data in the cavity 1. The difference is that the linkage between the first electromagnetic valve 3 and the second electromagnetic valve 4 is added in the present embodiment, and when the automatic drain port 1-2 is blocked or the first electromagnetic valve 3 fails to cause the automatic drain port 1-2 to drain condensed water, the second electromagnetic valve 4 is triggered to operate. The working mechanism is as follows: after the liquid level data is greater than the reference value (namely, the condensed water is required to be discharged), on the one hand, a signal is sent to trigger the first electromagnetic valve 3 to be opened, on the other hand, the timer T starts to count the time, if the duration time of the liquid level data greater than the reference value reaches the reference value of the second comparator C2, the automatic discharging port 1-2 can not discharge the condensed water, the second comparator C2 outputs a signal to the driving circuit of the second electromagnetic valve 4, and the second electromagnetic valve 4 is triggered to work, so that the condensed water is discharged. The timer T triggers to count under the output of the first comparator C1, and when the liquid level data is not greater than the reference value, the timer T is cleared.

The second electromagnetic valve 4 may be the same electromagnetic valve as the first electromagnetic valve 3, that is, the second electromagnetic valve 4 only works when the automatic discharging port 1-2 is abnormal, or may be a time-controlled electromagnetic valve, that is, the second electromagnetic valve 4 can perform timing discharging, or works when the automatic discharging port 1-2 is abnormal.

In this embodiment, the condensed water drain device further includes an alarm 7, the controller 6 further includes a third comparator C3, an input end of the third comparator C3 is connected to an output end of the timer T, and an output end of the third comparator C3 is connected to the alarm 7. The controller 6 further comprises a third input module I3, the third input module I3 being connected to the third comparator C3. The main purpose of this arrangement is to give an alarm when the second solenoid valve 4 is also unable to drain condensate, the mechanism of which is: after the liquid level data is greater than the reference value (i.e. the condensed water is required to be discharged), on one hand, a signal is sent to trigger the first electromagnetic valve 3 to be opened, on the other hand, the timer T starts to count time at the same time, if the duration of the liquid level data greater than the reference value reaches the reference value of the third comparator C3 (the reference value of the third comparator C3 should be greater than the reference value of the second comparator C2), the first electromagnetic valve 3 and the second electromagnetic valve 4 both receive the trigger signal, but the liquid level data does not drop to the normal value, thereby triggering an alarm and notifying the staff to check.

In this embodiment, the condensed water drain device further includes a prompting device 8, the controller 6 may further include a counter D and a fourth comparator C4, the output end of the second comparator C2 is connected to the counting input end of the counter D, the input end of the fourth comparator C4 is connected to the output end of the counter D, and the output end of the fourth comparator C4 is connected to the prompting device 8. The controller 6 further comprises a fourth input module I4, the fourth input module I4 being connected to the fourth comparator C4. The automatic discharge port 1-2 is arranged in such a way that the number of times of working of the second electromagnetic valve 4 caused by the abnormality of the automatic discharge port 1-2 is recorded, and a prompt is sent out through the prompt device 8 after a certain number of times is reached, so that workers are informed of the fault of the automatic discharge port 1-2, and hidden danger is eliminated conveniently. The counter D triggers counting (i.e., the second solenoid valve 4 works) under the output of the second comparator C2, and is cleared after the prompt is sent out by the prompt device 8 or manually cleared by a worker.

The input module may be a key or a touch screen, so that a reference value of the comparator may be input. The alarm 7 and the prompting device 8 can be a local audible and visual alarm and an audible and visual prompting device, and can also be added with a communication module, so that alarm information and prompting information are sent to a terminal of a worker. The controller 6 can be realized by a singlechip + comparison circuit, a timing circuit and the like, and can also be realized by a microprocessor, such as an AT89c51 chip and the like.
