Description

Technical Field

[0001] This utility model relates to the field of waste liquid recycling technology, and in particular to a waste liquid tank for laboratory use. Background Technology

[0002] Chemical laboratories inevitably generate hazardous substances during testing and research: flammable, explosive, toxic, corrosive, and environmentally harmful waste and waste liquids. Some of these, including wastewater containing heavy metals such as lead, cadmium, and chromium, as well as strong acid and alkali waste liquids and organic waste liquids, can pollute the surrounding environment, reduce water and soil quality, and even accumulate in the human body through the food chain, causing neurological and organ diseases. Therefore, virtually all chemical laboratories are considered significant sources of pollution and are subject to supervision by environmental and safety departments, with the treatment of hazardous waste liquids generated during experiments being of paramount importance. Generally, before being legally transferred, waste liquids need to be stored in safe containers in a separate space; commonly used storage containers are corrosion-resistant, acid and alkali-resistant, and airtight.

[0003] However, existing waste liquid containers still have some shortcomings and areas for improvement in practical use. When using existing waste liquid containers, the waste liquid often contains some solid waste. However, these solid wastes need to be stored separately from the liquid during recycling. However, existing waste liquid containers do not have the effect of solid-liquid separation. Furthermore, due to the container structure, waste liquid residue is easily left inside when emptying the recycled waste liquid. In addition, the overall corrosion resistance of existing waste liquid containers needs further improvement. Therefore, those skilled in the art have provided a laboratory waste liquid container to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laboratory waste liquid container. Through a discharge structure with an arc-shaped inner wall, the waste liquid can flow more effectively, reducing residue during pouring. The waste liquid is collected in a collection trough, and can then be discharged by removing the sealing plug from the discharge port. A filtration structure separates solids from liquids, allowing external measurement of the amount of solid waste. Furthermore, the container body is constructed from multiple layers of materials, improving overall performance and lifespan.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laboratory waste liquid container, comprising a container body, a top cover at the upper end of the container body, a discharge port at the center of the upper surface of the top cover, the lower end of the discharge port penetrating through the upper surface of the top cover and extending to the lower end, a sealing cap threadedly connected to the upper end of the discharge port, a filter structure at the center of the upper surface of both sides of the container body, a discharge structure at the center of the lower inner wall of the container body, the discharge structure including a collection trough at the center of the lower inner wall of the container body, a discharge hole at the lower end of the center of the front side wall of the container body in front of the collection trough, the discharge hole penetrating through the front side wall of the container body and extending to the interior of the collection trough, a sealing plug at the front side of the interior of the discharge hole, and sound-absorbing pads glued to the four opposite corners of the center of the lower surface of the container body.

[0006] Through the above technical solution, by setting the discharge structure and making the inner sidewall of the tank arc-shaped, the waste liquid can flow better, reducing the residue of waste liquid when poured. The waste liquid is collected in the inside of the collection tank, and then the waste liquid inside can be discharged by pulling out the sealing plug from the inside of the discharge hole. The filter structure can separate solids and liquids, and the amount of solid waste inside can be judged from the outside. At the same time, the tank body is made of multi-layer material mixture, which can improve the overall performance and service life.

[0007] Furthermore, the filter structure includes a filter screen, with connecting plates fixedly connected to both ends of the filter screen. An insert plate is provided on one side of each of the two connecting plates, and a movable hole is provided at the center of one side wall of each of the two insert plates. The other ends of the two connecting plates pass through the two movable holes and lead to the other side, and a limiting plate is connected to each end. A slot is provided at the center of the upper surface of both sides of the barrel, and the side walls of the two insert plates are slidably connected to the inside of the two slots.

[0008] With the above technical solution, when solid and liquid fall onto the filter screen at the same time, the solid remains at the top and the liquid continues to fall. As the amount of solid increases, the connecting plates at both ends will converge towards the middle. The amount of solid waste inside can be judged by observing the size of the movement of the two connecting plates into the tank. Then, the filter screen can be replaced after the two insert plates are slid out of the two slots and the two connecting plates and the two limiting plates are disassembled.

[0009] Furthermore, a reinforcing layer is provided inside the side wall of the barrel, and a protective layer and a corrosion-resistant layer are respectively provided on both sides of the reinforcing layer;

[0010] The above technical solution utilizes multiple materials to improve overall performance.

[0011] Furthermore, identification plates are fixedly connected to the center of the front and rear side walls of the barrel.

[0012] The above technical solutions effectively enhance brand recognition and improve identification.

[0013] Furthermore, handles are respectively provided at the upper center of the two side walls of the barrel;

[0014] The above technical solution facilitates its handling and processing.

[0015] Furthermore, a groove is provided on the upper surface of the filter screen, and the filter screen is made of corrosion-resistant resin;

[0016] The above technical solution can effectively contain solid waste, and the corrosion-resistant resin can improve the overall service life.

[0017] Furthermore, the two limiting plates are detachably connected to the two connecting plates;

[0018] The above technical solution facilitates disassembly and replacement.

[0019] Furthermore, the protective layer, the reinforcing layer, and the corrosion-resistant layer are made of glass fiber, ceramic, and polytetrafluoroethylene, respectively.

[0020] Through the above technical solutions, glass fiber has excellent strength, rigidity and corrosion resistance when used on the surface, ceramics can insulate against some high temperatures, and polytetrafluoroethylene has excellent chemical resistance. The combined use of these technologies improves the overall performance.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the barrel body is made of a mixture of multiple materials, which improves the overall performance and service life.

[0023] 2. In this utility model, by setting a filter structure, when solid and liquid fall onto the filter screen at the same time, the solid remains at the top and the liquid continues to fall. As the amount of solid increases, the connecting plates at both ends will converge towards the middle. From the outside, the amount of solid waste inside can be judged by observing the size of the movement of the two connecting plates into the barrel. Then, by sliding the two insert plates out of the two slots, the two connecting plates and the two limiting plates can be disassembled and the filter screen can be replaced.

[0024] 3. In this utility model, by setting a discharge structure and making the inner side wall of the barrel into an arc shape, the waste liquid can flow better, and the residue of waste liquid can be reduced when it is poured. The waste liquid is collected in the inside of the collection tank, and then the waste liquid inside can be discharged by pulling the sealing plug out from the inside of the discharge hole.
