Air floatation equipment with anti-blocking function for wastewater treatment

Abstract

The invention relates to air floatation equipment with an anti-blocking function for wastewater treatment. The equipment comprises a main body, an air flotation machine, a water inlet pipe, a slag discharging pipe, a moving device, a slag scraping plate, two adjusting mechanisms, two cleaning mechanisms and two connecting pipes; each adjusting mechanism comprises a lifting assembly, a transmissionassembly and a connecting assembly. The lifting assembly comprises a lifting plate, a telescopic frame, two hinge blocks and two moving units. Eachcleaning mechanism comprises a first bearing, a rotating shaft, a worm wheel, a scraping rod and a worm; according to the air floatation equipment with the anti-blocking function for wastewater treatment, the height of the slag scraping plate can be adjusted by the adjusting mechanism; the slag scraping requirements of waste water horizontal planes with different heights are met, the situation that the slag scraping plate cannot make contact with impurities and affects slag scraping work due to the fact that the waste water level is too low is prevented; the impurities adhering to the air outlet holes are scraped off through the cleaning mechanism, the air outlet hole blocking probability is reduced, and the air outlet holes are prevented from being blocked and affecting air floatation work.

Description

technical field [0001] The invention relates to the field of air flotation equipment, in particular to an air flotation equipment with anti-clogging function for wastewater treatment. Background technique [0002] Air flotation is an abbreviation of air flotation machine, and it can also be used as a proper noun, that is, the air flotation method in water treatment, which is to form highly dispersed micro-bubbles in water and adhere to solids or liquids with hydrophobic groups in wastewater. Particles form a three-phase mixed system of water, air and particles. After the particles adhere to the air bubbles, they form flocs with an apparent density lower than that of water and float to the water surface, forming a scum layer that is scraped off, thereby realizing solid-liquid or liquid-liquid separation. process. [0003] After the existing air flotation machine performs waste water treatment work for a long time, the impurities in the sewage are easy to block the air outlet...

AI Technical Summary

Problems solved by technology

[0003] After the existing air flotation machine performs waste water treatment work for a long time, the impurities in the sewage are easy to block the air outlet, thereby affecting the normal operation of the air flotation device. Not only that, the height of the slag scraper of the existing air flotation machine is fixed, It cannot be adjusted according to the liquid level of different heights, which greatly reduces the practicability of the existing air flotation machine
