Surrounding transmission scraper

Surrounding transmission scraperThe scraping and suction system mainly consists of a mud collection scraper and a connecting bracket, made of high-quality stainless steel plates and profiles. The sludge collection scraper collects the sludge from the bottom of the tank into the sludge tank, and uses the suction pipe installed here to press it into the pipeline collection tank and discharge it by utilizing the water level difference between it and the discharge tank.

The skim plate and articulated scraper rake are mainly made of high-quality stainless steel plates. The skimming plate is installed at the lower part of the main beam, closely attached to the central guide tube at the end of the pool center, and the gap between the other end and the skimming bucket is not more than 5mm. It is installed at a certain angle on the main beam to ensure that the floating slag in the pool is scraped from the center of the pool to the articulated scraping rake, and then scraped into the skimming bucket through the articulated scraping rake, and the scraped floating slag is discharged outside the pool.

Surrounding transmission scraperAdopting peripheral transmission, sewage flows in from the inlet pipe at the center of the pool, diffuses through the stabilizing cylinder, and flows out uniformly in a radial manner to the periphery. The suspended sludge settles at the bottom of the pool after sedimentation. The driving device drives the working bridge to rotate along the periphery and drives the scraper arm and scraper plate to rotate. The sludge is scraped from the periphery of the pool to the central mud collection tank, and then discharged from the pool through the sludge discharge pipe by the static water pressure inside the pool. The floating slag on the water surface is skimmed to the edge of the pool by the skimming device, and then scraped into the slag hopper by the scraper rake and discharged outside the pool; The supernatant overflows into the water outlet tank through a triangular weir plate and is discharged.

Main features

1. The working bridge can be of half bridge or full bridge type, and its material can be carbon steel, stainless steel, or aluminum alloy, etc;

2. The driving device adopts a shaft mounted helical gear reducer and an active roller direct transmission, with a compact structure and high mechanical efficiency;

3. The scraper collects mud in a logarithmic spiral trajectory, with good continuity and high efficiency in collecting mud;

4. When the slope of the pool bottom is 1:10, it can reduce the resistance during mud scraping;

5. Set up mechanical and electrical dual overload protection for reliable operation;

6. The equipment is easy to operate and can be directly controlled locally/remotely for its operation.

It is mainly used for mixing, stirring, and circulating in municipal and industrial wastewater treatment processes, and can also be used for the maintenance of landscape water environments. By rotating the impeller, it creates water flow, improves water quality, increases oxygen content in water, and effectively prevents the deposition of suspended solids. The process and industrial flow require a place where solid liquid two-phase or solid liquid gas three-phase media are uniformly mixed and reacted.
