Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a temporary drug adding device for a closed system without a water tank. Background Art

[0002] The tankless closed system is a modern hot water supply technology. Unlike the traditional hot water tank system, it achieves hot water supply by instantly heating the cold water flowing through the pipes, without the need for large water tanks. This system not only saves space, but also provides instant hot water quickly, reducing energy waste. It is widely used in sewage treatment and air purification.

[0003] At present, closed systems without water tanks usually adopt a systematic design for dosing devices, including batching, mixing and stirring, which take a certain amount of time to complete. However, in the fields of sewage treatment and air purification, temporary dosing is often required to deal with specific situations, such as dealing with sudden water quality problems or air pollution incidents. When using the above-mentioned systematic dosing devices, the required liquid medicine is often not replenished in time, which will prolong the entire workflow and affect the efficiency and speed of responding to emergencies.
