Description

Technical Field

[0001] The utility model relates to the technical field of automatic cleaning by adding medicine, in particular to a descaling device for adding medicine for a cooling tower. Background Art

[0002] The portable dosing descaling device is a device used for cleaning and maintenance of cooling towers. It usually consists of a dosing device and a mixing device. The dosing device is used to add an appropriate amount of detergent or disinfectant tablets to the cooling tower inlet pipe to keep the water quality safe and hygienic. The mixing device is used to fully blend the detergent and automatically send it into the cooling tower inlet water, and ensure that the disinfectant does not exceed a certain limit at one time. The use of the portable dosing descaling device can greatly simplify the maintenance of the cooling tower and improve the cleaning and sanitation effect. It reduces the need for manual operation and saves time and labor costs.

[0003] At present, cooling towers are usually used outdoors. Due to water quality problems, scale is easily formed and even algae may grow in the tower. Most cooling towers are cleaned by pouring disinfectants into the cooling tower. Although this method can play the role of adding medicine to clean, the cooling tower is large in size, and it is time-consuming and laborious for the workers to pour disinfectant tablets, and the operation is inconvenient. At the same time, pouring disposable disinfectant tablets into the cooling tower may cause excessive concentration, exceeding the safety limit, and causing harm to human health. In order to solve the above problems, a convenient dosing and descaling device for cooling towers is proposed. Utility Model Content
