一种设定水深的自动溢流装置
By designing an automatic overflow device with an overflow tank and a discharge depth adjustment lever, the problem of the existing overflow pipe's inability to flexibly adjust the overflow depth is solved, achieving precise control of the liquid level and selective discharge of specific liquids. This device is suitable for separating the floating oil layer and the clarified water in oily wastewater treatment.

AI Technical Summary
Existing overflow pipe designs cannot flexibly adjust the overflow depth, nor can they selectively discharge liquids at specific depths, especially when treating oily wastewater, as they cannot effectively separate the floating oil layer from the clarified water.
An automatic overflow device was designed, comprising an overflow tank, a downstream process tank, a horizontal overflow pipe, a vertical overflow pipe, and a drain depth adjustment lever. The drain depth adjustment lever is driven by external force to move up and down within the vertical overflow pipe, thereby achieving precise control of the liquid level and flexible adjustment of the overflow depth.
It achieves precise control of the liquid level in the water tank, and can selectively discharge liquid at a specific depth as needed, avoiding surface liquid overflow, improving ease of use and flexibility, and is suitable for separating the floating oil layer and the clarified water in the process of treating oily wastewater.
