Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1: As Figures 1 - 4 shown, the present utility model provides a technical solution: a medicine shortage alarm device applicable to the comprehensive treatment of laboratory sewage, including a placement table 1. A medicine storage cylinder 2 is arranged on the top of the placement table 1. One side top and bottom of the medicine storage cylinder 2 are symmetrically provided with stop valves 3. One end of the stop valve 3 is connected to a connecting pipe 4. One end of the connecting pipe 4 is connected to a monitoring component. A high-level alarm component is arranged outside the monitoring component. A low-level alarm component is arranged below the high-level alarm component. One end of both the high-level alarm component and the low-level alarm component is connected to a first connecting cable 5. One end of the first connecting cable 5 is connected to a PLC controller 6. The top of the PLC controller 6 is connected to a second connecting cable 7. One end of the second connecting cable 7 is connected to a display screen 8. One end of the top of the PLC controller 6 is connected to a third connecting cable 9. One end of the third connecting cable 9 is connected to an acoustic-optic module 10. A warning light 11 is arranged on one side of the acoustic-optic module 10. A buzzer 12 is arranged below the warning light 11.

[0023] In this embodiment, the remaining amount of medicine in the medicine storage cylinder 2 is monitored by the monitoring component. When the amount of medicine in the medicine storage cylinder 2 is too high or too low, the corresponding high-level alarm component or low-level alarm component will be triggered. The alarm information is transmitted to the PLC controller 6 through the first connecting cable 5. The PLC controller 6 controls the display screen 8 to display the alarm information through the second connecting cable 7 and the third connecting cable 9 respectively. At the same time, the warning light 11 flashes and the buzzer 12 emits a buzzer alarm, so as to realize the medicine shortage alarm in multiple ways, enabling the operator to quickly and timely receive the medicine shortage notice, and then carry out the medicine replenishment work, so as to maintain the stable operation of the entire laboratory sewage comprehensive treatment system and meet the actual use requirements. Among them, the PLC controller 6 is a known prior art to those skilled in the art. This solution is a related technical improvement to it, so its specific working principle will not be elaborated in detail in this article.

[0024] Embodiment 2: As Figures 1 - 4As shown in the figure, a control connection line 13 is connected to the top of the PLC controller 6. One end of the control connection line 13 is connected to a solenoid valve 14. The solenoid valve 14 is arranged at the top of the medicine storage cylinder 2. A medicine adding pipe 15 is arranged at the top of the solenoid valve 14. The monitoring component includes a monitoring cylinder 16. A buoy 17 is arranged inside the monitoring cylinder 16. The high-level alarm component includes a high-level alarm 18. One end of the high-level alarm 18 is connected to a first float switch 19. The first float switch 19 is arranged inside the monitoring cylinder 16. The low-level alarm component includes a low-level alarm 20. One end of the low-level alarm 20 is connected to a second float switch 21. The second float switch 21 is arranged inside the monitoring cylinder 16. A control valve 22 is arranged on one side of the medicine storage cylinder 2. One end of the control valve 22 is connected to a medicine outlet pipe 23. Four corners of the bottom of the placing table 1 are respectively provided with a footrest 24. The bottom of the footrest 24 is connected with an anti-slip pad 25.

[0025] In this embodiment, through the control connection line 13, the alarm information of the low-level alarm component can be used to control the opening of the solenoid valve 14, so that the supplementary medicine is added into the medicine storage cylinder 2 from the medicine adding pipe 15. At the same time, the alarm information of the high-level alarm component is used to control the closing of the solenoid valve 14, thus ending the medicine replenishment work. In this way, the automatic replenishment of the medicine storage cylinder 2 is realized according to the change of the alarm information, reducing the operation difficulty of manual medicine replenishment and saving labor and time costs. Through the connecting pipe 4, part of the medicine in the medicine storage cylinder 2 flows into the monitoring cylinder 16. When the liquid level of the liquid medicine drops, the buoy 17 drops with the liquid medicine and triggers the second float switch 21 to make the low-level alarm 20 send out a medicine shortage alarm. When the liquid level of the liquid medicine rises, the buoy 17 rises with the liquid medicine and triggers the first float switch 19 to make the high-level alarm 18 send out an alarm that the liquid level of the liquid medicine is too high. By opening the control valve 22, the liquid medicine in the medicine storage cylinder 2 can flow from the medicine outlet pipe 23 to the laboratory sewage comprehensive treatment system. The footrest 24 can provide effective support for the placing table 1, and at the same time, the anti-slip pad 25 is used to increase the friction with the ground, effectively preventing the placing table 1 from shaking.

[0026] Working principle of this embodiment: When in use, first, when the liquid medicine enters the medicine storage cylinder 2, part of the liquid medicine will flow into the monitoring cylinder 16 through the connecting pipe 4. Then, when the sewage comprehensive treatment system continuously consumes the liquid medicine, the liquid level of the liquid medicine gradually drops. At this time, the buoy 17 follows the drop of the liquid level of the liquid medicine, thereby triggering the second float switch 21, causing the low-level alarm 20 to send out a medicine shortage alarm. The medicine shortage information is transmitted to the PLC controller 6 through the first connecting cable 5. The PLC controller 6 controls the display screen 8 to display the medicine shortage alarm notification. At the same time, the warning light 11 flashes and the buzzer 12 emits a beeping sound to send the alarm notification to the operator. Then, the PLC controller 6 controls the solenoid valve 14 to open through the control wire 13, so that the replenished liquid medicine flows into the placement table 1 from the medicine adding pipe 15. Finally, when the liquid level of the liquid medicine in the medicine storage cylinder 2 gradually rises, the buoy 17 rises synchronously with the liquid level of the liquid medicine until the first float switch 19 is triggered by the buoy 17. The high-level alarm 18 transmits the alarm of too high liquid level of the liquid medicine to the PLC controller 6 through the first connecting cable 5. Then, the PLC controller 6 controls the solenoid valve 14 to close, cutting off the work of replenishing the liquid medicine, thus completing the use of the medicine shortage alarm device applicable to the comprehensive treatment of laboratory sewage.
