Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of waste liquid collecting barrels, especially relates to a laboratory waste liquid collecting barrel. BACKGROUND

[0002] In the laboratory environment, the collection and treatment of waste liquid is an indispensable part of daily work. The traditional waste liquid collection method often uses a simple container for storage, but this method has many shortcomings. For example, waste liquid directly falls into the container from a high place, which is easy to splash due to impact, not only polluting the laboratory environment, but also possibly causing safety hazards due to chemical reactions between waste liquids. In addition, the traditional waste liquid collection container lacks effective buffering and shunting mechanism, and the distribution of waste liquid in the container is uneven, which can easily cause local accumulation and backflow, causing inconvenience to the treatment and discharge of waste liquid.

[0003] There are some improved laboratory waste liquid collection devices on the market, which try to solve the problems of waste liquid splashing and uneven distribution by adding splash-proof plates, flow guide grooves and other structures. However, there are still some limitations, for example: although the splash-proof plate can reduce the splashing of waste liquid, it cannot effectively slow down the flow rate and disperse the impact force, which may still cause chemical reactions; while the flow guide groove can guide the flow direction of waste liquid, it is often complex in design, high in maintenance cost, and not suitable for all types of waste liquid.

[0004] Therefore, a more simple, practical and efficient laboratory waste liquid collection device is needed, which can not only avoid waste liquid splashing and chemical reactions, but also ensure uniform distribution of waste liquid in the container, facilitating subsequent treatment and discharge.
