Detachable low-circulation cavitation air floatation machine

Abstract

The invention discloses a detachable low-circulation cavitation air floatation machine, comprising an air floatation tank body that includes an aeration tank, an air floatation tank and a collection tank from left to right, the bottom of the air floatation tank body is provided with support legs, one side of the aeration tank is provided with an electric control switch and a sewage inlet, an aeration cavity is arranged in the aeration tank, a submersible aerator is fixedly connected to the bottom of the aeration cavity through bolts, a mixed discharge tray is arranged below the submersible aerator, and one side of the mixed discharge tray is provided with an intake pipe. The detachable tank body is provided herein, so that the problem that a traditional air floatation machine is not good for large-scale production is solved; a device capable of decreasing flow return rate is provided, so that the problem that gas-bearing impurities flow with a return flow and are unable to float in time due to an excessive reflow is solved; a filter device and settling device capable of purifying and settling sewage further are provided, so that the problem that discharged water receives poor purification is solved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an assembleable low-circulation vortex-concave air flotation machine. Background technique [0002] Vortex concave air flotation machine is an excellent sewage treatment technology with reasonable design, convenient operation and economical operation. It generates air bubbles from the air and directly removes suspended solids, grease, jelly and other impurities from wastewater. Vortex concave aeration The machine injects "micro-bubbles" directly into the sewage without dissolving air in advance, and then distributes the "micro-bubbles" evenly in the sewage through the diffuser impeller, so the whole operation process will not be blocked. The vortex concave air flotation machine is mainly composed of a box, an aerator, and a slag scraping system, and does not require pressure dissolved air, air compressors, and circulation pumps. [0003] However, the vortex ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a low-circulation vortex air flotation machine that can be assembled to solve the traditional vortex air flotation machine proposed in the above background technology. It is not conducive to quantitative production, and the excessive backflow of sewage flowing into the air flotation chamber makes the impurities mixed with gas in the sewage unable to float up in time with the backflow flow, and the sewage treatment effect is not ideal. After sewage treatment, it enters the water storage tank without further filtration and settlement. , leading to the problem that the discharged water purification effect is not ideal
