Air flotation tank scraperWorking principle explanation:

After entering the air flotation tank, the sewage first passes through the reaction zone, where small suspended particles are aggregated into larger particles through drug administration. Then it enters the contact zone with dissolved air and water, where fine bubbles in the dissolved air attach to the surface of the suspended particles, forming flocs with a specific gravity lower than that of water. In the separation zone, they float to the surface and form waste residue. The scraper is located above the isolation zone and periodically scrapes the waste residue into the slag discharge tank through reciprocating motion to achieve sewage purification. The equipment mainly consists of a driving device, a transmission chain, a sprocket, a traction chain, a sprocket, a scraper, a guide wheel, a tensioning device, a guide rail bracket, etc. By driving the chain through the driving device, the scraper is driven by the chain to make continuous rotary motion in the pool, thereby pulling the scraper on the chain to move. During operation, the sludge at the bottom of the pool is scraped into the mud collection tank, and the floating oil or floating slag on the pool surface can be scraped off to collect the sediment settled at the bottom into the mud collection tank. Reasonable structure, strong practicality, long service life, and easy installation and maintenance.

The air flotation tank scraper is specifically designed to remove grease, gel like substances, and suspended solids from industrial and urban wastewater. Especially suitable for scraping off floating slag generated in flocculation treatment processes. It applies the principle of chain transmission and can be installed according to different civil engineering requirements of users. According to the quality of the treated wastewater and the added chemicals, the scraping speed can be adjusted to achieve scraping tasks with low power consumption.

The air flotation tank scraper has the following advantages in structure:

1. Adopting a truss structure, the design considers the stability of the scraper operation and is easy to maintain and manage;

2. The driving mechanism adopts a long axis centralized form with two output shafts at both ends, with two sets of wheels, one set as the driving wheel and the other set as the driven wheel.

3. Independent flipping mechanism, using push rod flipping;

4. The operation of the slag scraper in the air flotation tank and the flipping of the scraper adopt two independent driving mechanisms, which are electrically controlled to switch and alternate between each other;

5. Compared with similar equipment, the air flotation tank scraper has a wide range of applications and is not limited by the large particles or high specific gravity contained in the water.
