Description

Technical Field

[0001] This utility model relates to the field of waste liquid tank technology, and in particular to a leak-proof, compartmentalized waste liquid tank. Background Technology

[0002] High-performance liquid chromatography (HPLC) is a separation and analysis instrument based on the difference in distribution between a mixture and a stationary phase and a mobile phase. It uses a high-pressure liquid delivery system to drive the sample solution through a chromatographic column, achieving separation by utilizing the differences in the interactions between different components and the stationary phase, and finally, quantitative analysis by a detector. Its core components include an injection system, a liquid delivery system, a separation system, and a detection system, combined with a data processing system to complete the qualitative and quantitative analysis of complex mixtures. HPLC is characterized by high efficiency, sensitivity, and wide applicability, and is widely used in pharmaceutical research and development, environmental monitoring, food safety, and biochemistry, especially suitable for the analysis of high-boiling-point and thermally unstable compounds.

[0003] Existing waste liquid collection containers for liquid chromatographs are mostly simple plastic containers with waste liquid tubing inserted directly into them. Gaps exist at the connection between the tubing and the container, making it easy for organic reagents to leak. Constant monitoring of the waste liquid level is crucial, as spillage is easily caused. Furthermore, the single-chamber design of the waste liquid container makes it susceptible to chemical reactions (such as gas generation and heat generation) when mixed with organic solvents, buffer salts, and strong acid / alkali waste liquids, increasing safety hazards and complicating subsequent treatment. To overcome these disadvantages, this invention provides a leak-proof, multi-chamber waste liquid container. Utility Model Content

The system includes a second three-way pipe with a third three-way pipe fixedly connected to one end, a third three-way solenoid valve fixedly connected to the third three-way pipe, a spectral sensor fixedly connected to the third three-way pipe and above the third three-way solenoid valve, a connection assembly at one end of the third three-way pipe and a viewing assembly at one side of the liquid storage chamber, a liquid level sensor fixedly connected to one side of the liquid storage chamber, the liquid level sensor's detection end observing the liquid storage chamber located inside the liquid storage chamber, a drain pipe fixedly connected to the outlet on one side of the liquid storage chamber, a valve fixedly connected to the drain pipe, a leak-proof assembly on the drain pipe, and a control panel fixedly connected to one side of the liquid storage chamber.

[0006] Furthermore, the partition material is polytetrafluoroethylene.

[0007] Furthermore, the connecting assembly includes a flexible hose fixedly connected to one end of a third tee pipe, and one end of the flexible hose is fixedly connected to a threaded connector.

[0008] Furthermore, the observation component includes several observation windows opened on one side of the liquid storage chamber, and glass is fixedly connected to the observation windows.

[0009] Furthermore, the leak-proof component includes a humidity sensor fixedly connected to the drain pipe, the detection end of the humidity sensor passing through the drain pipe and located inside the drain pipe, and a sealing ring fixedly connected to the outlet of the liquid storage chamber.

[0010] Furthermore, self-locking casters are fixedly connected to the four corners of the bottom of the base plate, and a push handle is fixedly connected to one side of the base plate.

[0011] The beneficial effects of this utility model are:

A humidity sensor on the leak-proof component detects whether there is any waste liquid leakage at the outlet, preventing untimely leaks from causing potential dangers. Attached Figure Description

One end of pipe 14 is fixedly connected to a third three-way pipe 17. A third three-way solenoid valve 18 is fixedly connected to the third three-way pipe 17. A spectral sensor 19 is fixedly connected to the third three-way pipe 17 and above the third three-way solenoid valve 18. One end of the third three-way pipe 17 is fixedly connected to one end of the first three-way pipe 11. A connecting component is provided at one end of the third three-way pipe 17. An observation component is provided on one side of the liquid storage chamber 24. A liquid level sensor 8 is fixedly connected to one side of the liquid storage chamber 24. The detection end of the liquid level sensor 8 observes the liquid storage chamber 24 located inside the liquid storage chamber 24. A drain pipe 4 is fixedly connected to the outlet on one side of the liquid storage chamber 24. A valve 5 is fixedly connected to the drain pipe 4. A leak-proof component is provided on the drain pipe 4. A control panel 22 is fixedly connected to one side of the liquid storage chamber 24.

[0021] like Figure 1-3 As shown, the material of the partition 25 is polytetrafluoroethylene, which can prevent the partition 25 from being corroded by waste liquid.

[0022] like Figure 1-3 As shown, the connection assembly includes a flexible hose 20 that is fixedly connected to one end of the third tee pipe 17. One end of the flexible hose 20 is fixedly connected to a threaded connector 21 for connecting to the external wastewater discharge equipment. After being fixed by the threaded connector 21, the connector does not require support from the operator.

[0023] like Figure 1-3 As shown, the observation assembly includes several observation windows 6 opened on one side of the liquid storage chamber 24, and glass 7 is fixedly connected to the observation windows 6 to facilitate the operator to observe the waste liquid storage status in the liquid storage chamber 24.

[0024] like Figure 1-3 As shown, the leak-proof component includes a humidity sensor 23 fixedly connected to the drain pipe 4. The detection end of the humidity sensor 23 passes through the drain pipe 4 and is located inside the drain pipe 4.

[0026] Working Principle: Before use, first check if the device is intact. After checking, connect each solenoid valve and sensor via control panel 22. Then connect the device to the instrument generating waste liquid via threaded connector 21. The waste liquid enters the third three-way pipe 17 through hose 20. The spectral sensor 19 then detects the waste liquid, identifying its type in real time through characteristic absorption peaks. The waste liquid then enters either the second three-way pipe 14 or the first three-way pipe 11 through the third three-way solenoid valve 18. When it enters the second three-way pipe 14, the conductivity sensor 16 detects the waste liquid, distinguishing between organic matter and buffer salts. Then, the second three-way solenoid valve 18... 5. Start-up allows waste liquid to enter the corresponding chamber. When it enters the first three-way pipe 11, the pH sensor 13 detects the pH value of the waste liquid to distinguish whether it is a strong acid or a strong alkali. Then, the first three-way solenoid valve 12 is activated, allowing the waste liquid to enter the corresponding chamber. The operator can observe the waste liquid in the chamber through the glass 7 on the observation window 6. The liquid level sensor 8 detects the volume of waste liquid in the chamber to determine whether it needs to be discharged. When waste liquid leaks, the humidity sensor 23 on the drain pipe 4 detects the humidity on the drain pipe 4 and sends the signal to the control panel 22 to warn the operator.
