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 ...

Embodiment Construction

[0025] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0026] Such as Figure 1-2 As shown, an intelligent air flotation device for collecting scum for sewage treatment includes a sewage tank 1, an air flotation machine 2, an inlet pipe 3, and a water outlet pipe 4. The air flotation machine 2 is arranged in the sewage tank 1. At the bottom of the inside, the inlet pipe 3 is set on one side of the sewage tank 1, the outlet pipe 4 is set on the other side of the sewage tank 1, and the outlet pipe 4 is provided with a valve 5, and also includes a top plate 6, a filter The plate 7, the annular plate 8, two pillars 9 and three moving mechanisms, the two pillars 9 are respectively arranged on both sides of the sewage tank 1, th...
