Description

Technical Field

[0001] This utility model belongs to the field of laboratory equipment technology, specifically relating to a laboratory water basin platform for collecting waste liquid. Background Technology

[0002] Laboratory water dispensers, as core infrastructure in scientific research fields such as chemistry, biology, and materials science, undertake crucial functions such as cleaning glassware before and after experiments and providing experimental water. During experimental operations, water dispensers are not only essential tools for ensuring the cleanliness of experimental equipment but also fundamental to maintaining the safe and orderly operation of the laboratory. Especially in chemical analysis laboratories, their cleaning function directly affects the accuracy of experimental results.

[0003] Currently, the water basins used in laboratories mainly consist of a cabinet and an operating table. The cabinet serves as a supporting structure, providing a reliable foundation for the entire setup. The operating table is installed on top of the cabinet, with a sink and faucet mounted on it. The faucet is positioned directly above the sink and connected to the laboratory's water source via a water supply pipe. The bottom of the sink is directly connected to the drain at the bottom of the cabinet via a dedicated pipe. After researchers use the faucet to clean glassware or perform other operations, the resulting cleaning water can be directly discharged through the drain.

[0004] However, during laboratory operations, residual liquids in experimental equipment often contain hazardous substances and cannot be directly discharged into the sewer system. This necessitates that researchers first transfer the waste liquid from the equipment to a specially designated waste liquid container in the laboratory before returning to the sink to wash the equipment. The resulting wastewater, containing trace amounts of hazardous components, must then be transferred back to the waste liquid container. This frequent back-and-forth movement between the sink and the waste liquid container not only significantly reduces experimental efficiency and increases operational time costs, but also carries the risk of accidental spills due to collisions or slips with other personnel, leading to contamination of the laboratory floor and equipment, and even endangering personnel safety. Utility Model Content

[0005] This invention addresses the problem that laboratory personnel need to frequently travel between the water basin and the waste liquid container when cleaning glassware, which not only reduces experimental efficiency but also poses a risk of waste liquid spillage. It provides a laboratory water basin that can collect waste liquid by integrating the waste liquid container into the water basin, without reducing experimental efficiency or posing a risk of waste liquid spillage.

[0006] To solve the above problems, the technical solution adopted by this utility model is a laboratory sink table for collecting waste liquid, including a cabinet. An operating table is installed on the top of the cabinet, and a tabletop is installed on the top of the operating table. A washbasin and a waste liquid collection tank are set on the tabletop. A faucet is installed above the washbasin and fixed to the top of the tabletop. The bottom of the washbasin is connected to the upper end of a drain pipe, and the lower end of the drain pipe is connected to a sewer at the bottom of the cabinet. The bottom of the waste liquid collection tank is connected to one end of a collection pipe, and the other end of the collection pipe is connected to a waste liquid bucket located inside the cabinet.

[0007] In this technical solution, the bottom of the waste liquid collection tank is connected to one end of a collection pipe, and the other end of the collection pipe extends into the cabinet, connecting to the waste liquid bucket placed inside. When researchers need to clean experimental equipment, they can directly obtain cleaning water from the tap and pour the original waste liquid in the equipment, as well as the waste liquid generated during the cleaning process, into the waste liquid collection tank. The waste liquid then flows through the collection pipe into the waste liquid bucket for collection. Therefore, this device integrates the waste liquid collection process into the water basin, avoiding the need for researchers to shuttle between the water basin and the waste liquid bucket, thus improving experimental efficiency and effectively avoiding the risk of waste liquid spillage.

[0008] Furthermore, the collection pipe includes a first connecting pipe and a second connecting pipe. The first connecting pipe is located above the second connecting pipe. The upper end of the first connecting pipe is connected to the bottom of the waste liquid collection tank, and the lower end of the first connecting pipe is connected to one end of the inlet valve. The other end of the inlet valve is connected to the upper end of the second connecting pipe, and the lower end of the second connecting pipe is connected to the waste liquid tank. The inlet valve provides a controllable switch for the waste liquid flow. When the waste liquid tank is full and needs to be replaced, the operator can close the inlet valve in advance, immediately cutting off the passage between the first and second connecting pipes. In this way, the residual waste liquid in the first connecting pipe is blocked by the valve and cannot continue to flow downwards, avoiding the problem of waste liquid dripping and contaminating the cabinet.

[0009] Furthermore, the waste liquid container includes a container body with an internal cavity, and a lid fixed to the top of the container body. During tilting, collision, or bumping of the waste liquid container, the lid can prevent the internal waste liquid from overflowing from the container opening, thus avoiding contamination of the laboratory floor, cabinets, and surrounding equipment.

[0010] Furthermore, a cam-locking quick connector is installed on the top of the lid. The male connector of the cam-locking quick connector connects to the lower end of the second connecting tube, and the female connector connects to the upper end of the infusion tube. The lower end of the infusion tube passes through the lid and connects to the cavity. When changing the waste liquid container, the experimenter only needs to rotate the cam handle to unlock, which quickly disconnects the connection between the second connecting tube and the waste liquid container. The entire process takes only a few seconds, significantly reducing the operation time of traditional threaded or snap-fit ​​connections. When installing a new waste liquid container, simply align the interface and rotate the handle to complete the connection. This is especially suitable for high-frequency experimental scenarios that require frequent waste liquid container changes.

[0011] Furthermore, handles are fixed to the outer wall of the container, and casters are installed at the bottom. The handles allow researchers to easily apply horizontal pulling force, avoiding the effort and inconvenience of directly lifting the lid or holding the container. The casters support 360° free rotation, allowing the waste liquid container to easily turn, move straight, or adjust its direction in the confined space of the laboratory. Movement can be completed by a single person, reducing labor costs and operational difficulty.

[0012] Furthermore, a transparent observation window is installed on the side wall of the tank. Through the transparent observation window, made of transparent material, the level of waste liquid inside the tank can be directly viewed without opening the lid or pouring it out for estimation, thus avoiding odor leakage or operational risks caused by opening the lid.

[0013] Furthermore, a gas adsorption unit is fixed inside the barrel, located at the top of the cavity. This unit directly adsorbs the odor emitted from the waste liquid, reducing odor leakage by intercepting gas molecules. This improves the laboratory environment without complex operations, avoiding odor pollution and safety hazards caused by the diffusion of volatile gases, and simply and efficiently enhancing the safety and comfort of waste liquid storage.

[0014] Furthermore, a drain pipe is installed on the outside of the container. One end of the drain pipe penetrates the side wall of the container and communicates with the cavity, while the other end is connected to a drain valve. When the container is full, there is no need to move or empty it. The drain valve controls the drain pipe to connect directly to the recycling equipment or processing container, avoiding the risk of waste liquid splashing or volatile gas leakage during manual handling.

[0015] Furthermore, the front side of the cabinet has two doors, both hinged to the cabinet body. The two doors correspond to the areas below the washbasin and the waste collection tank, respectively. For the waste collection tank area, the separate door prevents accidental contact with hazardous waste liquid during washbasin maintenance and facilitates separate sealing or protection of the waste liquid area, complying with laboratory safety regulations.

[0016] Furthermore, a drying board is fixed to the top of the worktable, and several drying racks are installed on the drying board. By installing several drying boards above the worktable, the planar operating space is extended to a three-dimensional space, allowing multiple experimental vessels to be dried simultaneously.

[0017] As can be seen from the above technical solution, the advantages of this utility model are as follows: In this technical solution, the bottom of the waste liquid collection tank is connected to the waste liquid bucket built into the cabinet via a collection pipe. When the experimenter cleans the glassware, they can directly use the faucet water and pour the original waste liquid from the glassware and the waste liquid generated during cleaning into the waste liquid collection tank. Under the action of gravity, the waste liquid automatically flows into the sealed waste liquid bucket through the collection pipe to complete the collection. In summary, this device, by integrating the waste liquid collection process into the design of the water basin, eliminates the need for experimenters to travel back and forth between the water basin and the waste liquid bucket, effectively improving experimental efficiency. Furthermore, the closed transmission path significantly reduces the risk of waste liquid spillage, achieving safe and efficient waste liquid management. Attached Figure Description

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] A laboratory sink table for collecting waste liquid, such as Figure 1 As shown, the system includes a cabinet 1, with an operating table 13 mounted on top of the cabinet 1. A tabletop 2 is mounted on top of the operating table 13. Two pre-reserved slots of different sizes are located in the middle of the tabletop 2. A washbasin 3 is installed in the larger slot, and a wastewater collection tank 4 is installed in the smaller slot. Both the washbasin 3 and the wastewater collection tank 4 are made of corrosion-resistant metal. A drain pipe 31 is located below the washbasin 3, inside the cabinet 1. The upper end of the drain pipe 31 connects to the bottom of the washbasin 3, and the lower end connects to the drain at the bottom of the cabinet 1. The drain pipe 31 is used to drain wastewater from the washbasin 3. A collection pipe 5 is located below the wastewater collection tank 4. One end of the collection pipe 5 connects to the bottom of the wastewater collection tank 4, and the other end connects to a wastewater container 6. The wastewater container 6 is used to store wastewater. Both the collection pipe 5 and the wastewater container 6 are located inside the cabinet 1.

[0026] In this specific embodiment, cabinet 1 adopts the following structure: cabinet 1 is generally rectangular, and a water supply pipe is installed inside cabinet 1. One end of the water supply pipe is connected to the laboratory water source, and the other end is connected to a faucet 21. The faucet 21 is fixedly installed on the top of the tabletop 2 and located above the washbasin 3. The faucet 21 is equipped with a three-way spout for easy cleaning of experimental instruments of different sizes. A vertically arranged drying board 22 is provided on the outside of the faucet 21. The bottom of the drying board 22 is fixedly connected to the top of the tabletop 2. Several drying racks 23 are installed on the surface of the drying board 22 for hanging cleaned experimental instruments for drying. Two hinged cabinet doors 11 are provided on the front side of cabinet 1. The two cabinet doors 11 correspond to the area below the washbasin 3 and the area below the waste liquid collection tank 4, respectively, and a partition is provided between these two areas. A support leg 12 is fixed at the bottom corner of the cabinet 1. The support leg 12 provides support for the cabinet 1 while leaving a gap between the bottom of the cabinet 1 and the ground, making it easy to clean the ground under the cabinet 1.

[0027] In this specific embodiment, the collection pipe 5 adopts the following structure: the collection pipe 5 includes a first connecting pipe 51 and a second connecting pipe 52. The first connecting pipe 51 is located above the second connecting pipe 52. The upper end of the first connecting pipe 51 is connected to the bottom of the waste liquid collection tank 4, and the lower end of the first connecting pipe 51 is connected to one end of the inlet valve 53. The other end of the inlet valve 53 is connected to the upper end of the second connecting pipe 52, and the lower end of the second connecting pipe 52 is connected to the waste liquid tank 6. In this embodiment, the inlet valve 53 is a ball valve. When the waste liquid tank 6 is full and needs to be replaced, the operator closes the ball valve in advance, which immediately cuts off the passage between the first connecting pipe 51 and the second connecting pipe 52, so that the waste liquid remaining in the first connecting pipe 51 is blocked by the ball valve and cannot continue to flow downward, thus preventing waste liquid from dripping and contaminating the cabinet 1.

[0028] like Figure 2 As shown, in this specific embodiment, the waste liquid tank 6 adopts the following structure: the waste liquid tank 6 includes a tank body 61, the tank body 61 is a cylinder with an internal cavity 66, and a tank cover 64 is fixed to the top of the tank body 61 by bolts. Figure 4 As shown, a gas adsorption unit 67 is installed at the top of the internal cavity 66 of the barrel 61. The gas adsorption unit 67 includes a screen that is snapped onto the inner wall of the barrel 61, and the screen is filled with activated carbon for adsorbing the volatile gases emitted from the waste liquid. Figure 3 As shown, a cam-locking quick connector 7 is installed above the lid 64. This cam-locking quick connector 7 is an existing device. The male connector 71 of the cam-locking quick connector 7 connects to the lower end of the second connecting pipe 52, and the female connector 72 connects to the upper end of the infusion pipe 73. The lower end of the infusion pipe 73 passes through the lid 64 and the gas adsorption unit 67 and connects to the cavity 66. A transparent observation window 62 made of transparent glass is installed on the side wall of the barrel 61, allowing observation of the waste liquid level without opening the lid 64. A handle 63 is welded to the outer wall of the barrel 61, and casters 65 supporting 360° free rotation are installed at the bottom of the barrel 61, facilitating the pulling and orientation adjustment of the waste liquid barrel 6 in confined laboratory spaces. A drain pipe 8 is installed on the outside of the barrel 61. One end of the drain pipe 8 passes through the side wall of the barrel 61 and connects to the bottom of the cavity 66. The other end is connected to the drain valve 81. The drain valve 81 is a ball valve. When it is necessary to discharge waste liquid, the ball valve can be opened to discharge the waste liquid from the drain pipe 8.

[0029] The specific usage process of this utility model is as follows: When it is necessary to clean experimental instruments, firstly, pour the original waste liquid in the experimental instruments into the waste liquid collection tank 4, then turn on the tap 21 to use the experimental instruments to rinse them, and pour the rinsed waste liquid back into the waste liquid collection tank 4. After that, hang the cleaned experimental instruments on the drying rack 23 to air dry. The waste liquid in the waste liquid collection tank 4 passes sequentially through the first connecting pipe 51, the inlet valve 53 which is in the open state, the second connecting pipe 52, the male connector 71 and female connector 72 of the cam-locking quick connector 7, and the infusion pipe 73, and is finally injected into and stored in the cavity 66 of the waste liquid tank 6. When it is observed through the transparent observation window 62 that the waste liquid in the waste liquid tank 6 is full and needs to be treated, rotate the handle of the inlet valve 53 to close the inlet valve 53, cutting off the waste liquid flow path. Then, rotate the cam handle on the female connector 72 of the cam-locking quick connector 7 to separate the female connector 72 and the male connector 71. At this time, pull the handle 63 to use the casters 65 at the bottom of the waste liquid tank 6 to pull the waste liquid tank 6 out of the cabinet 1 and move it to the special waste liquid treatment area. Then, rotate the handle of the drain valve 81 to open the drain valve 81, and the waste liquid in the waste liquid tank 6 can be discharged from the drain pipe 8. Finally, the waste liquid is centrally treated.

[0030] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: In this specific embodiment, the bottom of the waste liquid collection tank is connected to the waste liquid bucket built into the cabinet via a collection pipe. When the experimenter cleans the glassware, they can directly use the faucet water and pour the original waste liquid from the glassware and the waste liquid generated during cleaning into the waste liquid collection tank. Under the action of gravity, the waste liquid automatically flows into the sealed waste liquid bucket through the collection pipe to complete the collection. In summary, this device, by integrating the waste liquid collection process into the design of the water basin, eliminates the need for experimenters to travel back and forth between the water basin and the waste liquid bucket, effectively improving experimental efficiency. Furthermore, the closed transmission path significantly reduces the risk of waste liquid spillage, achieving safe and efficient waste liquid management.
