Floatation machine level adjusting mechanism

Abstract

This invention relates to a level adjustment unit for an air-floating machine composed of two water blocking boards and an adjustment unit including a notch nut, an open-end pin, a sealing loop, a screw rod, rubber pads and a square nut characterizing that one blocking board is fixed and the other is put closing to the fixed one with a runner moving by the adjustment unit, and the top edges of both two boards include a row of water breaches and the area of which is less than that of the closed part between adjacent water notches. Advantages: 1, strong wear ability to fluctuation of water flow, 2, practical and effective, easy to be operated especially for places with limit spaces, 3, evident result in removing dregs, 4, bright prospect for commercial development.

Description

(1) Technical field: [0001] The invention relates to a sewage treatment machine, in particular to an air flotation machine provided with a liquid level adjustment mechanism. (two) background technology: [0002] The air flotation machine is a common equipment for sewage treatment. It relies on the generation of a large number of tiny air bubbles in the water to attach to the suspended solids to make the suspended solids float to the water surface to form scum, which is then scraped off with a scraper device. Generally speaking, in the scum scraping device, there is a supporting plate with one end obliquely inserted under the scum and the other end protruding from the water surface. The height of the supporting plate and the liquid level determines the effect of scum scraping. The scum scraping device used in the air flotation machine is basically the same. , the difference lies in the way of adjusting the height of the liquid level. There are currently two ways: setting a fl...

Generally speaking, in the scum scraping device, there is a supporting plate with one end obliquely inserted under the scum and the other end protruding from the water surface. The height of the supporting plate and the liquid level determines the effect of scum scraping. The scum scraping device used in the air flotation machine is basically the same. , the difference lies in the way of adjusting the height of the liquid level. There are currently two ways: setting a flow regulating valve on the outlet pipeline, which is not suitable for promotion due to poor tolerance to influent flow fluctuations; the other is to adjust the outlet weir The height of the board is very good, but the outlet weir board must be placed in a position that is easy to adjust, which greatly limits the layout of the air flotation device design, and it is more troublesome to adjust
