[0002] Liquid chromatograph refers to an instrument that uses the difference in the distribution ratio of the mixture between liquid-solid or two immiscible liquids to separate the mixture first and then analyze and identify it. Most laboratories produce waste liquid. Leaving the waste liquid discharged will cause environmental pollution. Therefore, the waste liquid needs to be collected and centrally treated. Commercially available waste liquid collection barrels have built-in waste treatment systems to reduce the discharge of waste in the laboratory and reduce environmental pollution. However, there is a risk of full liquid leakage in existing collection barrels when in use, which is easy to cause pollution.

The disadvantage of this utility model is that there is no water level alarm device, and the waste liquid is easy to overflow. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art that the waste liquid collection bucket lacks a monitoring device and is prone to liquid leakage, and provides a liquid chromatograph waste liquid collection device which can give an alarm when the collection bucket is about to be full of liquid.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A liquid chromatograph waste liquid collection device comprises a storage tank, an alarm component and a liquid leakage concentration component. The upper end of the storage tank is provided with an opening, one end of the alarm component is mounted on the storage tank, the other end of the alarm component passes through the opening and is placed in the storage tank, and the liquid leakage concentration component is mounted on the side of the storage tank.

[0007] The storage tank is used to store waste liquid generated during the experiment. The waste liquid enters the storage tank from the opening for storage. When the waste liquid is stored, as the water level rises, it will be monitored by the alarm component. When it is detected that the water level has reached a certain height and is about to overflow, the alarm component will sound an alarm. If the alarm is not stopped in time after the alarm, the leaked liquid will enter the leakage collection component to prevent liquid leakage, ensure the clean environment of the laboratory, and achieve the purpose of sounding an alarm when the collection bucket is about to be full.

[0008] Preferably, a liquid inlet pipe is provided at the opening of the storage tank, the liquid inlet pipe corresponds to the opening of the storage tank and is installed on the storage tank, a collecting pipe is provided on the storage tank, one end of the collecting pipe passes through the liquid inlet pipe and is placed in the storage tank, and a handle ring is installed on the storage tank. The liquid inlet pipe is installed at the opening of the storage tank, and the storage tank can be closed by the liquid inlet pipe, which is convenient for the use of the storage tank. The inlet height can be increased by the liquid inlet pipe to prevent splashing during liquid injection. A collecting pipe is placed on the liquid inlet pipe of the storage tank to collect waste liquid, and the collecting pipe is extended into the storage tank for liquid injection to reduce splashing of the liquid in the storage tank. At the same time, a handle ring is installed on the storage tank to facilitate the movement of the storage tank. Such a design facilitates the movement of the storage tank.

[0009] Preferably, the alarm assembly includes a water level sensor, a wire and a controller. The water level sensor is placed in the storage tank. The water level sensor is electrically connected to the controller via a wire. The controller is installed on the top surface of the storage tank. An alarm is installed on the controller. The alarm is electrically connected to the controller. The water level sensor of the alarm assembly is placed in the storage tank to monitor the water level in the storage tank. After the water level sensor monitors, the data is transmitted to the controller via a wire. The controller processes the monitoring data of the water level sensor. When the water level sensor monitors that the water level in the storage tank is too high and is about to overflow, an alarm is sounded to prevent the waste liquid from overflowing. Such a design facilitates the monitoring of the water level.

[0010] Preferably, the water level sensor is provided with a fixing assembly, and the fixing assembly includes a fixing plate and a card plate. The fixing plate is placed on one side of the water level sensor and contacts the water level sensor. The lower end of the fixing plate is connected to the inner bottom surface of the storage tank. Card plates are provided on both sides of the water level sensor. One end of the card plate is connected to the water level sensor, and the other end of the card plate corresponds to the water level sensor. The water level sensor needs to be fixed in the storage tank by a fixing assembly to ensure that the water level sensor is placed vertically and improve the accuracy of water level monitoring. The water level sensor contacts the fixing plate, and the fixing plate is installed on the bottom surface of the storage tank. The water level sensor is in a vertical state by contacting the fixing plate. The two sides of the water level sensor in the vertical state are limited by the card plate. The limited water level sensor is limited by the card plate, which is convenient for installing and disassembling the water level sensor. Such a design is convenient for fixing the water level sensor.

During use, if an alarm is triggered when overflow is imminent and the storage tank is not replaced in time, a small amount of overflow will occur, and the overflowed waste liquid will cause laboratory pollution. The waste liquid overflowing after reaching the liquid inlet pipe will enter the annular groove for collection, will not be dispersed, and is easy to collect. The waste liquid in the annular groove will flow along the drainage groove to the side of the storage tank, and under the guidance of the drainage groove, it will enter the collection box installed on the side of the storage tank. The collection box collects a small amount of overflowed liquid, which is easy to handle and will not pollute the laboratory. Such a design can collect a small amount of overflowed waste liquid.
