Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a wastewater treatment dosing device. Background Technology

[0002] Wastewater refers to wastewater and waste liquid generated during industrial production and daily life, including industrial wastewater, industrial sewage, and cooling water. Since industrial wastewater often contains a variety of toxic substances, it pollutes the environment and poses a great threat to human health. Therefore, it needs to be treated before it can be discharged. Wastewater treatment requires the addition of chemicals to decompose, absorb, and precipitate harmful substances in the wastewater.

[0003] A search of Chinese patents revealed publication number CN217051746U, which discloses a wastewater treatment dosing device. This utility model wastewater treatment dosing device includes a support section, a chemical storage section, a collection and discharge section, and an adjustable discharge section. The chemical storage section is positioned on the support section, and the collection and discharge section is located at the bottom of the chemical storage section to collect and discharge any leakage from it. An internal connecting pipe is located inside the chemical storage section, and this internal connecting pipe communicates with the adjustable discharge section via an external connecting pipe. The adjustable discharge section is mounted on the support section and has a horizontally movable adjustment mechanism. The outlet end of the external connecting pipe is connected to the adjustment mechanism to adjust the discharge position. This utility model wastewater treatment dosing device is easy to operate, facilitating both adjustment of the chemical discharge position and collection of any leakage.

[0004] Existing dosing devices struggle to provide uniform dosing. In general wastewater treatment, dosing devices are required to add chemicals to the treatment tank. However, these tanks are typically large, and conventional dosing devices can only add chemicals at fixed locations, necessitating multiple dosing attempts. This leads to uneven dosing, affecting treatment effectiveness, increasing workload, and reducing efficiency. Furthermore, conventional dosing devices lack a mixing function, resulting in concentrated chemicals that are difficult to disperse quickly, further reducing treatment efficiency. Additionally, some chemicals may settle at the bottom of the treatment tank, reducing effective utilization and impacting the stability of subsequent treatment processes. To address these issues, we propose a wastewater treatment dosing device. Utility Model Content
