Intelligent-type air floatation device convenient for floating residue collection in sewage treatment

Abstract

The invention relates to an intelligent air flotation device for sewage treatment which is convenient for collecting scum, including a sewage tank, an air flotation machine, a filter plate, an annular plate and three moving mechanisms. The mechanism includes a floating block, a notch, an opening, a vertical bar and a limit assembly. The moving mechanism includes a translation assembly and a lifting assembly. The lifting assembly includes a first motor, a first drive shaft, a wire reel, and a suspension wire. The intelligent air flotation device, which is convenient for collecting scum, realizes through the closing mechanism that after the filter plate is separated from the liquid surface, the floating blocks block the openings and notches, so that the scum can stop on the filter plate and realize solid-liquid separation. When separating, the filter plate moves upward, so that the equipment can treat different sewage volumes. Not only that, the three moving mechanisms drive the filter plate to lift and move, and control the inclination of the filter plate, so that the scum can flow from the opening on the ring plate. It can be dropped anywhere, which is convenient for people to collect, thus improving the practicability of the device.

Description

Technical field [0001] The invention relates to the field of environmental protection and energy-saving equipment, and in particular to an intelligent air flotation device for sewage treatment that is convenient for collecting scum. Background technique [0002] In recent years, with the rapid development of industry, the discharge of various industrial waste water and sewage has increased. In order to reduce environmental pollution and facilitate the sustainable development of society, people usually need to treat various types of sewage. Among them, air floatation is A commonly used method to treat industrial wastewater. Air flotation refers to the formation of highly dispersed tiny bubbles in water, and solid or liquid particles that adhere to the hydrophobic base in the sewage to form a three-phase mixed system of water, air and particles. After the particles adhere to the bubbles, the apparent density is less than The flocs of water float up to the water surface, forming a ...

Problems solved by technology

[0003] However, in the existing air flotation device, the height and position of the scraper is usually fixed, which requires a certain amount of water flowing into the sewage tank. When the amount of sewage is too much or too little, the scraper cannot function to the scum layer on the liquid surface, thereby limiting the practicability of the existing air flotation device, not only that, the rotation of the scraper only concentrates the scum layer on the liquid surface in one place, and is located at the center of the liquid surface in the sewage pool The scum at the center, because it is far away from the pool wall, makes it difficult for people to collect the scum at the center, which increases the difficulty of sewage treatment
