Description

Technical Field

[0001] The utility model relates to the technical field of laboratory waste liquid collection devices, in particular to an organic reagent waste liquid early warning device. Background Art

[0002] In physical and chemical analysis laboratories, chromatography-mass spectrometry is the main detection equipment. When using chromatography-mass spectrometry, a variety of organic reagents are used, such as acetonitrile, methanol, n-hexane, etc. These reagents will enter the pipeline through the injection system. After the injection reaction is completed, the excess liquid after the reaction is switched to the waste liquid discharge pipeline, and then discharged to the waste liquid collection container outside the instrument through the waste liquid discharge pipeline.

[0003] At present, multiple high-performance liquid chromatography-tandem mass spectrometers are commonly used in physical and chemical analysis laboratories, and each high-performance liquid chromatography-tandem mass spectrometer has a matching waste liquid collection container. Due to the different daily sample volumes, the amount of waste liquid generated is also different, and it is impossible to estimate the full point of the waste liquid collection container. The operator can only observe the liquid level from time to time and discharge and clean it in time. However, due to untimely cleaning, waste liquid often overflows, which not only pollutes the working environment, but also increases the workload.

[0004] In order to solve the above problems, the prior art has developed a waste liquid warning device, such as a waste liquid automatic collection and filtration warning safety device disclosed in CN 212541504U, which is provided with a plate body, a first support rod, a cross rod, a transmission rod, a float, a filter screen, a top rod, a first clamping block, a connecting block and a trigger mechanism. The elastic rope is contracted to drive the movable rod to fall and the driving protrusion strikes the bell, so that the bell makes a sound, thereby achieving the purpose of early warning.

[0005] However, even after the warning is issued, if the operator is not on site or cannot discharge and clean up in time due to other reasons, there is still a risk of waste liquid overflow and polluting the working environment. To this end, we propose a new type of organic reagent waste liquid warning device to provide dual guarantees for the warning of waste liquid collection and timely discharge. Utility Model Content

The buoyancy ball is located inside the waste liquid collection box, and the top of the buoyancy ball is connected to the transmission component. When the buoyancy ball rises, the transmission component activates the alarm of the early warning component.

[0012] The early warning component is located outside the waste liquid collection box and is activated by the transmission component to sound an alarm.

The button switch circuit of the early warning assembly is connected, and an alarm is sounded, which can serve as an early warning for the staff. When an early warning is issued, if the staff still fails to clean up the waste liquid in time, the amount of waste liquid inside the waste liquid collection box will continue to increase, and the liquid level will continue to move upward. When the liquid level exceeds the top of the overflow pipe, the pressure outside the waste liquid collection box is greater than the pressure inside the waste liquid collection box, so the waste liquid inside the waste liquid collection box can flow into the overflow box through the diversion cavity, which can share the waste liquid inside the waste liquid collection box and effectively prevent waste liquid from overflowing and polluting the environment.

[0024] In summary, the organic reagent waste liquid early warning device provided by the utility model provides a double guarantee for the early warning and timely discharge of organic reagent waste liquid collection in the physical and chemical analysis room. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figure 1 to Figure 6 shown.

[0036] The utility model provides an organic reagent waste liquid early warning device, comprising a waste liquid collection box 1, an overflow component, a suspension component and an early warning component; wherein:

[0037] The waste liquid collection box 1 is provided with a waste liquid inlet 24 at the top, and a cover can be provided on the waste liquid inlet 24. A first liquid discharge pipe 19 is provided at the bottom of one side of the waste liquid collection box 1, and a valve is provided on the first liquid discharge pipe 19. When it is necessary to collect waste liquid discharged from the high performance liquid chromatography tandem mass spectrometer, the waste liquid discharge pipeline is inserted into the waste liquid inlet 24. When the waste liquid collection box 1 is full or the valve on the first liquid discharge pipe 19 is opened regularly, the waste liquid in the waste liquid collection box 1 can be discharged.

[0038] The overflow assembly includes an overflow pipe 2 and an overflow box 3. The overflow pipe 2 is located inside the waste liquid collection box 1, and it longitudinally penetrates the bottom of the waste liquid collection box 1 and extends to the inside of the overflow box 3; an inverted U-shaped guide cavity 22 is opened inside the overflow pipe 2, and one end of the guide cavity 22 forms a guide port 23, and the guide port 23 is located at the bottom of the waste liquid collection box 1, and the other end of the guide cavity 22 is connected to the overflow box 3. The waste liquid inside the waste liquid collection box 1 enters the guide cavity 22 through the guide port 23 of the overflow pipe 2. When the liquid level in the waste liquid collection box 1 exceeds the top of the overflow pipe 2, since the external pressure is greater than the internal pressure of the waste liquid collection box 1, the waste liquid inside the waste liquid collection box 1 can flow into the overflow box 3 through the guide cavity 22, which can share the waste liquid inside the waste liquid collection box 1 and effectively prevent the waste liquid from overflowing.

[0039] The overflow box 3 is located outside the waste liquid collection box 1; specifically, a leg frame 18 is fixedly connected to the lower surface of the waste liquid collection box 1, and the overflow box 3 is arranged on the leg frame 18. In a preferred embodiment, a second drain pipe 20 is arranged at the bottom of one side of the overflow box 3, and a valve is arranged on the second drain pipe 20. When the overflow box 3 is full or the valve on the second drain pipe 20 is opened regularly, the waste liquid in the overflow box 3 can be discharged.

[0040] In a preferred embodiment, in order to facilitate observation of the interior of the waste liquid collection box 1 and the overflow box 3 so as to discharge the waste liquid in time, liquid level windows 21 are provided on the front of the waste liquid collection box 1 and the overflow box 3 .

[0041] The suspension component includes a buoyancy ball 12 and a transmission component. The buoyancy ball 12 is located inside the waste liquid collection box 1, and the top of the buoyancy ball 12 is connected to the transmission component. When the buoyancy ball 12 rises, the early warning component alarm is activated through the transmission component.

[0042] Specifically, the transmission component includes a gear rod 5 , a gear 6 , a rotating shaft 7 , a connecting frame 8 and a pressure column 9 . The gear rod 5 is arranged longitudinally, and the bottom of the gear rod 5 is connected to a buoyancy ball 12 .

[0043] In a preferred embodiment, in order to facilitate the disassembly and assembly of the buoyancy ball 12, the gear rod 5 is connected to the buoyancy ball 12 by threads, the lower surface of the gear rod 5 is fixedly connected with a threaded seat 10, and the top of the buoyancy ball 12 is fixedly connected with a threaded column 11, and the threaded column 11 is threadedly connected to the inside of the threaded seat 10.

[0044] The outer surface of the gear rod 5 is meshed with a gear 6, and the middle of the gear 6 is fixedly connected with a rotating shaft 7. Specifically, the rotating shaft 7 is installed on a support frame 13 through a bearing, and the support frame 13 is fixedly connected to the upper surface of the waste liquid collection box 1, so that the gear 6 can rotate more smoothly. The two ends of the rotating shaft 7 are fixedly connected to the connecting frame 8, and the lower surface of the connecting frame 8 is fixedly connected with a pressure column 9, which is used to trigger the button switch 14 of the warning component.

[0045] When in use, as the amount of waste liquid in the waste liquid collection box 1 increases, the buoyancy ball 12 is pushed upward, and when the gear rod 5 is driven upward, the gear 6 can be rotated, and during the rotation of the gear 6, the connecting frame 8 can be driven to rotate. When the connecting frame 8 is rotated to a certain position, the connecting frame 8 just rotates to the top of the button switch 14 of the warning component, and the pressure column 9 can apply pressure to the button switch 14, thereby triggering the warning component.

[0046] In a preferred embodiment, in order to ensure the stability of the up and down movement of the gear rod 5 , the bottom of the gear rod 5 is connected to a limit ring 4 through a cross bar, and the limit ring 4 is sleeved on the outer surface of the overflow pipe 2 .

[0047] The early warning component is located outside the waste liquid collection box 1 and is activated by the transmission component to sound an alarm. The early warning component can be set to remind the staff, and the staff does not need to pay attention to the liquid level of the waste liquid all the time. In a preferred embodiment, in order to improve the early warning effect, the early warning component can use a combination of sound alarm and photoelectric alarm to sound an alarm.

[0048] Specifically, the early warning component includes a button switch 14, an alarm 15, an alarm light 16 and a battery 17. The button switch 14 is electrically connected to the alarm 15 via a wire, the alarm 15 is electrically connected to the alarm light 16 via a wire, the alarm light 16 is electrically connected to the battery 17 via a wire, and the battery 17 is electrically connected to the button switch 14 via a wire.

[0049] By applying pressure to the button switch 14 through the pressure column 9, the circuit of the button switch 14 is turned on, and the alarm 15 emits an alarm sound and the alarm light 16 lights up, which can serve as an early warning to the staff.

[0050] After the warning occurs, if the staff still fails to clean up the waste liquid in time, the amount of waste liquid inside the waste liquid collection box 1 will continue to increase, and the liquid level will continue to move upward. When the liquid level exceeds the top of the overflow pipe 2, the external pressure of the waste liquid collection box 1 is greater than the internal pressure of the waste liquid collection box 1, and the waste liquid inside the waste liquid collection box 1 can flow into the overflow box 3 through the guide cavity 22, which can share the waste liquid inside the waste liquid collection box 1 and effectively prevent the waste liquid from overflowing the environment.

[0051] In summary, the organic reagent waste liquid early warning device provided by the utility model provides a double guarantee for the early warning and timely discharge of organic reagent waste liquid collection in the physical and chemical analysis room.
