Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory waste liquid treatment technology, specifically to a recycling device for hazardous laboratory waste liquid. Background Technology
[0002] Currently, laboratories often use simple collection containers to handle hazardous waste liquids, which poses a risk of leakage. Furthermore, mixing different types of waste liquids can easily lead to chemical reactions and create hazards. For example, mixing certain strong oxidizing waste liquids with reducing waste liquids may cause an explosion. Existing waste liquid recovery devices are simple in structure and lack effective separation, collection, and leak-proof measures. They cannot adequately isolate waste liquids of different properties, leading to cross-contamination, and their inadequate sealing structures can easily cause toxic waste liquids to volatilize or leak, polluting the laboratory environment and endangering personnel health. Utility Model Content
[0003] The purpose of this invention is to provide a device for recycling hazardous waste liquids in laboratories, so as to solve the problems mentioned in the background art.
[0004] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0005] A device for recycling hazardous waste liquids in laboratories includes a conveying mechanism and a collection mechanism.
[0006] Furthermore, the conveying mechanism includes a pair of fixed frames, a pair of fixed rods connected between the pair of fixed frames, and a plurality of liquid separators installed between the pair of fixed rods. The collection mechanism includes a fixed base, and a plurality of collection boxes are provided on the top surface of the fixed base. The top surface of the collection box has an opening, and a sealing element is installed in the opening. The sealing element is used to seal the opening, and a one-way valve is inserted in the sealing element. A hose is connected between the liquid separator and the one-way valve. Waste liquid flows into the hose through the liquid separator and enters the collection box through the one-way valve. Each type of waste liquid corresponds to one liquid separator, thus achieving the purpose of classifying and collecting waste liquid, thereby preventing cross-contamination of waste liquid and avoiding chemical reactions between waste liquids.
[0007] Furthermore, the sealing element includes a sealing cap and a sealing plug. The sealing plug is installed on the bottom surface of the sealing cap and seals the opening. The sealing cap covers the opening. The combined design of the sealing cap and the sealing plug enhances the sealing performance of the collection box, further reducing the possibility of waste liquid leakage and volatilization, and protecting the laboratory environment and personnel safety.
[0008] Furthermore, the sealing plug is a rubber plug, which has good elasticity and sealing properties, can fit tightly to the opening of the collection box, effectively prevents waste liquid leakage and gas evaporation, and is low in cost and easy to replace.
[0009] Furthermore, the one-way valve penetrates the sealing cover and sealing plug and extends into the interior of the collection box. Several sealing rings are installed on the outside of the one-way valve. The sealing rings on the outside of the one-way valve further enhance the sealing between the one-way valve and the sealing cover and sealing plug, preventing waste liquid from leaking from the connection between the one-way valve and the sealing element, ensuring the normal operation of the one-way valve, improving the reliability of the device, and preventing the gas generated by the waste liquid from overflowing from the opening.
[0010] Furthermore, a float-type liquid level sensor is installed on the top of the collection tank, and the detection end of the float-type liquid level sensor is located inside the collection tank. When the liquid level of the waste liquid in the collection tank rises, the float rises accordingly. The float-type liquid level sensor detects the change in liquid level and transmits a signal. The float-type liquid level sensor can be connected to an external buzzer. After the liquid level reaches the set value, the float-type liquid level sensor sends a signal to the buzzer, causing the buzzer to sound an alarm to notify the surrounding staff, so as to prevent the waste liquid from overflowing from the collection tank.
[0011] Furthermore, the top surface of the fixed base is equipped with several fixed frames, and the collection box is installed in the fixed frames. The fixed frames can fix and position the collection box to prevent it from shaking or tipping over during use.
[0012] Furthermore, the bottom surface of the fixed base is equipped with four sets of casters, and the side of the fixed base is equipped with a handle. The design of the casters and handles makes the device easy to move, allowing experimenters to flexibly adjust the position of the device according to experimental needs and improving the practicality of the device.
[0013] Furthermore, the number of collection boxes is greater than the number of separators, which can meet the different waste liquid volumes generated by different experiments, ensure that the device has sufficient collection capacity, and improve the applicability and versatility of the device.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the recycling device for hazardous waste liquid in the laboratory realizes the classified collection of hazardous waste liquid, reducing the risk of mixed reactions of different waste liquids; the perfect sealing structure and one-way valve design effectively prevent waste liquid leakage and volatilization, protecting the laboratory environment and personnel health; the liquid level sensor and multi-collection tank design improve the convenience and safety of use; the movable design makes it easy to adjust the position of the device according to experimental needs.

Each type of waste liquid corresponds to one liquid separator 1003, so the purpose of classifying and collecting waste liquid can be achieved, thereby preventing cross-contamination of waste liquid and avoiding chemical reactions between waste liquids.
[0024] As an embodiment of this utility model, the sealing element further includes a sealing cap 2008 and a sealing plug. The sealing plug is installed on the bottom surface of the sealing cap 2008 and seals the opening. The sealing cap 2008 covers the opening.

[0025] As one embodiment of this utility model, the sealing plug is further made of rubber.

[0026] As an embodiment of this utility model, the one-way valve 2009 further penetrates the sealing cover 2008 and the sealing plug, and extends into the interior of the collection box 2005. Several sealing rings are installed on the outside of the one-way valve 2009. The sealing rings on the outside of the one-way valve 2009 further enhance the sealing performance between the one-way valve and the sealing cover 2008 and the sealing plug, prevent waste liquid from leaking from the connection between the one-way valve 2009 and the sealing element, ensure the normal operation of the one-way valve 2009, improve the reliability of the device, and prevent the gas generated by the waste liquid from overflowing from the opening.
[0027] As an embodiment of this utility model, a float-type liquid level sensor 2006 is further installed on the top of the collection tank 2005, and the detection end of the float-type liquid level sensor 2006 is located inside the collection tank 2005. When the waste liquid level in the collection tank 2005 rises, the float rises accordingly. The float-type liquid level sensor 2006 detects the liquid level change and transmits a signal. The float-type liquid level sensor 2006 can be connected to an external buzzer. After the liquid level reaches the set value, the float-type liquid level sensor 2006 sends a signal to the buzzer, causing the buzzer to sound an alarm to notify the surrounding staff, so as to prevent the waste liquid from overflowing from the collection tank 2005.
[0028] As an embodiment of this utility model, further, a plurality of fixing frames 2004 are installed on the top surface of the fixing base 2001, and the collection box 2005 is installed in the fixing frame 2004.

[0030] As one embodiment of this utility model, the number of collection boxes 2005 is greater than the number of separators 1003, which can meet the differences in the amount of waste liquid generated by different experiments, ensure that the device has sufficient collection capacity, and improve the applicability and versatility of the device.
[0031] Specifically, the working principle of this laboratory hazardous waste liquid recovery device is as follows: During use, the mounting bracket 1001 is first vertically installed inside the fume hood, ensuring it is positioned above the water tank. The experimental apparatus that generates hazardous waste liquid is then placed above the separator 1003. During the experiment, the waste liquid flows naturally into the separator 1003 due to gravity. Since each type of waste liquid corresponds to a separator 1003, preliminary sorting is achieved. The sorted waste liquid flows along the hose 2007 to the one-way valve 2009 under gravity. The waste liquid passes through the one-way valve 2009... The waste liquid then enters the collection tank 2005. As the waste liquid in the collection tank 2005 increases, the liquid level gradually rises. The float of the float-type liquid level sensor 2006 will rise accordingly. When the liquid level reaches the set warning value, the float-type liquid level sensor 2006 detects the liquid level change and transmits the signal to the external buzzer. The buzzer sounds an alarm to remind the experimenters to deal with the situation in time and avoid the waste liquid from overflowing. After collection is completed, the fixed base 2001 is pushed to send the collection tank 2005 to the hazardous waste storage. Finally, the waste liquid in the collection tank 2005 is treated.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control circuits of the buzzer and float-type liquid level sensor can be implemented by those skilled in the art through simple design and are common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
