Description

Technical Field

[0001] This utility model relates to the field of laboratory waste treatment technology, and in particular to a device for classifying and collecting experimental waste liquid used in activated carbon research and development. Background Technology

[0002] Proper management of laboratory waste liquids is a crucial aspect of safety management in activated carbon research laboratories. The preparation and modification of activated carbon often involve processes such as acid washing, alkali leaching, chemical activation, metal loading, and solvent desorption, generating a wide variety of complex laboratory waste liquids, including strong acids, strong alkalis, heavy metal ions, and organic solvents—all hazardous wastes. Improper handling of these waste liquids can trigger violent chemical reactions, release toxic gases, and cause environmental pollution and personal injury. Therefore, timely, safe, and categorized collection of waste liquids is of paramount importance.

[0003] However, most laboratories still collect waste liquids in a decentralized and non-standardized manner, usually using ordinary plastic buckets or reagent bottles placed randomly on the lab bench or in a corner, relying solely on paper labels for differentiation. This method has obvious drawbacks: waste liquids of different properties are easily mixed, and once acids, alkalis, or oxidants come into contact with reducing agents, it may cause safety accidents such as splashing or explosion. At the same time, paper labels are easily affected by moisture, corrosion, or fall off, resulting in the loss of classification information.

[0004] Therefore, it is necessary to design a device for classifying and collecting experimental waste liquid used in activated carbon research and development in order to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of existing laboratories that use plastic buckets or reagent bottles to store waste liquids haphazardly, relying solely on paper labels for differentiation, which can easily lead to mixed storage and safety accidents, and whose labels are prone to moisture damage and falling off, resulting in information loss, this utility model provides a waste liquid classification and collection device for activated carbon research and development.

[0006] The technical implementation scheme of this utility model is as follows: a waste liquid classification and collection device for activated carbon research and development, including a main box, a door panel, a first handle, a pusher, a tray, waste liquid bottles, a sealing cap, an L-shaped limiting rod, and a transparent label. The front of the main box is connected to the door panel by a hinge. The first handle is installed on the right side of the front of the door panel. The pusher is installed on the left side of the top of the main box. The inside of the main box is provided with three layers of trays from top to bottom. Multiple waste liquid bottles are equidistantly connected to each tray. The top of each waste liquid bottle is threaded with a sealing cap. An L-shaped limiting rod is provided at the rear of each waste liquid bottle. The vertical section of the L-shaped limiting rod is slidably connected to the tray. A transparent label is provided at the front of each tray corresponding to the position of each waste liquid bottle.

[0007] More preferably, it also includes an activated carbon filter layer, a cover plate, and a second handle. A ventilation hole is provided on the front side of the top center of the main body, and an activated carbon filter layer is provided inside the ventilation hole. A cover plate is rotatably connected to the front side of the top center of the main body via a hinge. The cover plate covers the ventilation hole, and a second handle is installed on the front side of the top center of the cover plate.

[0008] More preferably, it also includes a toolbox and a third handle. The toolbox is symmetrically slidably connected to the lower side of the main body, and a third handle is provided at the front of both toolboxes.

[0009] More preferably, it also includes LED lighting, with LED lights installed on the top of the main housing and at the bottom of the upper and middle trays.

[0010] More preferably, it also includes casters, with casters symmetrically installed on the left and right sides of the bottom of the main body.

[0014] 2. This utility model achieves the effects of effectively adsorbing volatile harmful gases, improving the operator's field of vision, improving the accuracy of waste liquid dumping and the safety of the working environment by setting ventilation holes with activated carbon filter layers and opening cover plates on the top of the main body, and LED lights that automatically light up when the door is opened. At the same time, it is convenient for regular maintenance.

[0015] 3.

[0022] Example: A device for classifying and collecting experimental waste liquid used in activated carbon research and development, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a main body 1, a door panel 2, a first handle 3, a push handle 4, a tray 5, waste liquid bottles 6, a sealing cap 7, an L-shaped limiting rod 8, and a transparent label 9. The front of the main body 1 is hinged to the door panel 2. The first handle 3 is installed on the right side of the front of the door panel 2. The push handle 4 is installed on the top left side of the main body 1. Inside the main body 1, there are three layers of trays 5 from top to bottom. Multiple waste liquid bottles 6 are equidistantly connected to each tray 5. Each waste liquid bottle 6 has a sealing cap 7 threaded to its top. Each waste liquid bottle 6 has an L-shaped limiting rod 8 at its rear. The vertical section of the L-shaped limiting rod 8 is slidably connected to the tray 5. A transparent label 9 is provided on the front of each tray 5 corresponding to the position of each waste liquid bottle 6.

[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes an activated carbon filter layer 10, a cover plate 11, and a second handle 12. A ventilation hole is provided on the front side of the top center of the main box 1, and an activated carbon filter layer 10 is provided inside the ventilation hole. The cover plate 11 is rotatably connected to the front side of the top center of the main box 1 by a hinge. The cover plate 11 covers the ventilation hole, and the second handle 12 is installed on the front side of the top center of the cover plate 11.

[0024] like Figure 2 and Figure 5As shown, it also includes a toolbox 13 and a third handle 14. The toolbox 13 is symmetrically slidably connected to the lower side of the main body 1. The front of both toolboxes 13 is provided with a third handle 14.

[0025] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it also includes LED lights 15, casters 16, shelves 17 and absorbent cotton 18. LED lights 15 are installed on the top of the main body 1 and the bottom of the upper and middle trays 5. Casters 16 are symmetrically installed on the left and right sides of the bottom of the main body 1. Shelves 17 are installed on the left outer wall of the main body 1. Absorbent cotton 18 is placed on each waste liquid bottle 6 on the three trays 5. The waste liquid bottle 6 is placed on the absorbent cotton 18.

[0026] When this device is needed, the operator first holds the push handle 4 and uses the casters 16 to move the device smoothly to the designated work area in the laboratory. The device is then secured by the braking function of the casters 16, ensuring that the device is stable and reliable during operation and preventing displacement or tipping due to external forces, thus improving the flexibility and safety of the equipment.

[0027] Then, grasp the first handle 3 and turn to open the door panel 2 connected by the hinge, so that the interior space of the main box 1 is fully exposed, which facilitates the collection of waste liquid. When collecting waste liquid by category, the operator selects the corresponding waste liquid bottle 6 according to the chemical properties of the waste liquid, such as strong acid, strong alkali, containing organic solvents or heavy metals. Each tray 5 has a transparent label 9 at the front corresponding to each waste liquid bottle 6. The label clearly indicates the collection category of the corresponding waste liquid bottle 6, ensuring accurate classification of waste liquid and avoiding violent reactions or the generation of toxic gases caused by mixing waste liquids of different properties.

[0028] Next, remove the sealing cap 7 of the waste liquid bottle 6 by rotating it counterclockwise. Slowly pour the waste liquid generated in the experiment into the waste liquid bottle 6 through a funnel. After pouring, immediately tighten the sealing cap 7 clockwise to achieve effective sealing, reduce the volatilization of harmful gases, and ensure operational safety. Each waste liquid bottle 6 is equipped with an L-shaped limiting rod 8 at the rear. The vertical section of the L-shaped limiting rod 8 is slidably connected to the support plate 5, which effectively limits the movement range of the waste liquid bottle 6 on the support plate 5, preventing it from tipping over or slipping during operation or accidental collision, and ensuring the stability and safety of the storage process.

[0029] If volatile organic compounds or irritating gases are present during waste liquid storage, they can be discharged to the outside through the ventilation holes. The ventilation holes are equipped with activated carbon filter layers 10, which can effectively adsorb harmful components in the waste gas and reduce pollution to the laboratory air. When it is necessary to replace the activated carbon filter layer 10, the second handle 12 can be held and the cover plate 11 connected by the hinge can be turned to open, so as to easily remove the old filter layer and replace it with new activated carbon material. After the cover plate 11 is closed, it can prevent dust from entering and keep the filtration system clean.

[0030] LED lights 15 are installed on the top of the main body 1 and at the bottom of the upper and middle trays 5. When the door panel 2 is opened, the LED lights 15 will automatically turn on to provide sufficient light for the operator, ensuring that the contents of the transparent label 9 can be clearly identified and the waste liquid can be accurately poured even in low light conditions, thus avoiding mis-disposal. The shelf 17 installed on the outer wall of the left side of the main body 1 can be used to temporarily place notebooks, pens or small experimental consumables, improving the convenience of operation.

[0031] In addition, toolboxes 13 are symmetrically slidably connected to the lower side of the main body 1. Each toolbox 13 has a third handle 14 at the front, which can be pulled out for use. The toolboxes can store commonly used tools such as funnels, gloves, and tweezers, enabling centralized management and quick access to tools. Each waste liquid bottle 6 is placed on the three-layer tray 5 with absorbent cotton 18. The waste liquid bottle 6 is placed on the absorbent cotton 18. In the event of bottle breakage or leakage due to poor sealing, the absorbent cotton 18 can quickly absorb the overflowing liquid, preventing it from spreading on the tray 5, effectively controlling the pollution range and improving the safety protection capability of the device.
